Description

Docking pipe measurement standard line take-up device

Technical field

The invention belongs to aid, specifically a kind of before large-scale pipe is docked, as the take-up device of measurement standard lines during two interface centerings.

Background technology

In the manufacturing process of large-scale steel structure machinery, many components adopt pipe docking to form, and especially resembles the strut of the harbour heavy mechanical equipment such as overhead crane, rail mounted crane, and its docking length reaches more than 30 meter.The interface of two pipes must being aligned before pipe docking, welding again when determining that the linearity of two pipe docking meets the requirements.At present, the linearity measuring two pipes is generally adopt the mode of drawing standard lines, namely two people are with pulling fine rule rope two ends, stride across the tension of docking pipe two external end head as standard lines, observation along the line is from standard lines to the distance of docking pipe outer tube wall, if distance error in allowed limits, namely represent that the linearity of two pipes is qualified.Because the length of pipe docking is longer, employment pulls the flexible general line of band, draws not tight measuring error large, easily breaks again when La get Tai is tight; Make standard lines with iron wire, staff directly draws also cannot be strained, and measuring error is still very large.

Summary of the invention

Technical matters to be solved by this invention is, overcomes the standard lines that linearity is measured in the docking of prior art two pipe, is not easy tension, the shortcoming that measuring error is large with staff direct cable, provides a kind of docking pipe measurement standard line take-up device.

In order to solve the problems referred to above that prior art exists, the present invention be adopt following technical proposals realize: can be clamped in the U-shaped on pipe one end pipe wall folder outside be fixed with support, the center line of line roller is vertical with pipe, be supported on support rotationally, the iron wire that line roller is wound around is adjacent on described U-shaped presss from both sides, and may extend across two docking pipes, guide into can be clamped on the pipe external end head tube wall of opposite, size another U-shaped identical of pressing from both sides with above-mentioned U-shaped is adjacent to fixing above pressing from both sides.

The present invention also has following technical characteristic:

On the U-shaped upper wall of described two U-shapeds folder, be separately installed with and iron wire is pressed in U-shaped folder line pressing bolt above;

Be provided with ratchet on the bracket, described ratchet coordinates with the hard-wired ratchet in line roller one termination, forms the ratchet device of defence line roller reversion.

During use, first will two pipe ends of docking be needed relative, then being clamped by fixing standoff U-shaped is clipped on the external end head tube wall of a pipe, the U-shaped of not belt supporting frame is clamped on the external end head tube wall being clipped in docking pipe, be supported on the iron wire that the line roller on support is wound around, above the U-shaped folder of belt supporting frame, guide another U-shaped folder be installed on another pipe end tube wall into and above fix.Rotational line roller makes iron wire strain, and by the distance of ruler multimetering iron wire to circular tube external wall, if distance error in allowed limits, just can weld; If distance error over range, of will adjust in docking pipe ensures the linearity of two pipes.

Advantage of the present invention and good effect are, due to pipe docking measure linearity time with tight wire as standard lines, one end of iron wire is fixed on above unsupported U-shaped folder and is adjacent to, and the other end is adjacent to above the U-shaped of the size identical belt supporting frame pressed from both sides with above-mentioned U-shaped press from both sides, then fixes around to line roller, rotational line roller tension iron wire is as measurement standard line, replace people's finger-tight with machinery, tension is easily, fast, easy to use, measuring error is little, accurately and reliably.Said apparatus structure is simple, when adjust a pair pipe docking fixing after, unload said apparatus and refill to clip on next docking pipe and use, can Reusability, easy accessibility.

Accompanying drawing explanation

Fig. 1 is perspective view of the present invention;

Fig. 2 is the U-shaped clamping structure enlarged drawing in A portion in Fig. 1.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

In Fig. 1, on the right end tube wall of the U-shaped open card pipe 4 on the right of U-shaped folder 6, hold out against with the trip bolt 6.1 be screwed on the upper wall 6.2 of U-shaped folder 6; On the left end head tube wall of left side pipe 4, with trip bolt 1.1 be screwed in U-shaped folder 1 upper wall 1.2 on hold out against.The right side leaving pipe 4 of U-shaped folder 6 is fixed with frame set 10, and the center line of line roller 7 and the central axis of pipe 4, two ends bearings is on the wall of support 10.The iron wire 3 that line roller 7 is wound around through described U-shaped folder 6 upper wall 6.2 above and be adjacent to, stride across two, left and right docking pipes 4, guide into press from both sides with U-shaped above upper wall 1.2 that the identical U-shaped of 6 size presss from both sides 1 and be adjacent to (see Fig. 2).

Because described U-shaped folder 1 is identical with the size of U-shaped folder 6, the thickness consistent size of upper wall 6.2 thickness and described upper wall 1.2, the height of U-shaped opening 1.3 too, and be fixed on the two ends of butt tube equally, tight wire 3 is attached to again above described upper wall 6.2 and upper wall 1.2, like this, only when the distance that the iron wire 3 as measurement standard line arrives left and right two butt tube is all consistent, the linearity of butt tube just meets the requirements.

In order to make measurement more accurate, must make iron wire 3 and U-shaped press from both sides 1 and U-shaped press from both sides 6 fit tight above, on described upper wall 1.2 and upper wall 6.2, be separately installed with the line pressing bolt 2 at compression iron wire 3 two ends.

During use, first will two pipe 4 terminations of docking be needed relative, by the weld seam 5 roughly centering between pipe, then the U-shaped being fixed with support 10 is pressed from both sides 6 clampings on pipe 4 right end tube wall, U-shaped is pressed from both sides 1 clamping on the left end head tube wall of left side docking pipe 4, support the iron wire 3 that line roller 7 is over the mount 10 wound around, above U-shaped folder 6, guide in the line pressing bolt 2 above the U-shaped folder 1 on the left of being installed on pipe 4 left end head tube wall and be fixed, rotational line roller 7 makes iron wire 3 strain, and the same line pressing bolt 2 of right-hand member is pressed abd fixed on above U-shaped folder 6.By the distance of ruler multimetering iron wire 3 to pipe 4 outer wall, if distance error in allowed limits, just can weld.This ensures that there the linearity of two pipes.In order to rotational line roller 7 convenience, one end of online roller 7 is provided with the hole 7.1 of slotting rocking bar 7.2.

In order to prevent the reversion of straining line roller 7 when iron wire 3 adjusts at rotational line roller 7, described support 10 is provided with ratchet 9, the ratchet 8 that described ratchet 9 is fixed with line roller 7 one termination coordinates, and forms the ratchet device that lock-in line roller 7 can only rotate to a direction.
