Abstract
The invention relates to a cylindrical resilient clamper. A hydraulic type clamper which is used for an existing drilling rig mostly relays on a spring to tightly clamp oil pressure and loosen the oil pressure and a clamping device is in transversal arrangement with a feeding machine body. According to the structure, the axial size of the clamper is longer. The condition that holes are drilled in multiple dig angles is limited under the limitation of width of the drilling rig on site. According to the cylindrical resilient clamper, the clamper utilizes a cylindrical box body structure. The clamper comprises a slip bowl, a slip, a cylinder body outer shell, a support base, a central pipe and a disc spring. The central pipe is installed in the slip bowl in a penetrating mode. A box body is arranged on the support base. A blocking ring is arranged at the inner front end of the outer shell of the clamper cylinder body. The cylinder outer shell, the slip bowl and the blocking ring form a reinforcement oil cylinder cavity. A main oil cylinder cavity is arranged at the back end of the cavity body. A reinforcement oil cylinder is added on the clamper so as to achieve reinforcement clamping. Clamping reliability of a drilling rod is effectively guaranteed.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
referring to Fig. 1, Fig. 2, a kind of cylindric multiple power clamper, its clamper adopts cylindric body structure, comprise slip spider 7, slips 8, cylinder body shell 6, bearing 14, central tube 15, dish spring 9, cylinder body shell 6 consists of master cylinder with slip spider 7, central tube 15 is arranged in slip spider 7, casing is arranged on bearing 14, the Inner Front End of clamper cylinder body shell 6 is provided with baffle ring 16, cylinder body shell 6, slip spider 7 and baffle ring 16 consist of boosting oil cylinder, cylinder body shell 6 consists of master cylinder with slip spider 7, the front end cavity that cylinder body shell 6 and slip spider 7 surround is boosting oil cylinder chamber 17, the rear end cavity is master cylinder chamber 18, boosting oil cylinder chamber 17 is connected with boosting oil cylinder fuel inlet neck 4, master cylinder chamber 18 is connected with master cylinder fuel inlet neck 5.
Cylindric body structure is made of front apron 3, cylinder body shell 6, backboard 10, and cylinder body shell 6 is connected with backboard with front apron 3 by screw and is connected.
The front end of clamper is provided with righting board 1, and its material is high-abrasive material.
Be respectively arranged with front nut 2 and back nut 12 before and after the casing of clamper, front nut 2 is connected with the front and back of central tube 15 with the mode that back nut is connected to be threaded, and adjusts back nut 12 and be threaded into the pretightning force that the degree of depth can change dish spring 9 on central tube 15.
Operating principle of the present invention is:
(1) clamp the drilling rod operation
The present invention is the normally closed type clamper.Under nature, master cylinder chamber 18 and boosting oil cylinder chamber 17 all do not have the hydraulic oil effect, and dish spring 9 passes to slips 8 by slip spider 7 with chucking power under the effect of pretightning force, and slips 8 moves to the direction near the central tube center, with drill-rod clamping.When the larger clamping force of needs, enter hydraulic oil by boosting oil cylinder fuel inlet neck 4 in boosting oil cylinder chamber 17, master cylinder this moment chamber 18 is fuel feeding not, hydraulic oil acts on baffle ring 16, baffle ring 16 with force transmission to slip spider 7 and slips 8.The active force that boosting oil cylinder chamber 17 produces is consistent with the clamping force direction that dish spring 9 produces.Therefore, the chucking power that this moment, drilling rod was subject to is the active force sum of dish spring 9 and boosting oil cylinder chamber 18 generations.
(2) unclamp the drilling rod operation
Enter hydraulic oil by master cylinder fuel inlet neck 5 in master cylinder chamber 18, boosting oil cylinder chamber 17 interior fuel cut-offs, the thrust that the hydraulic oils in master cylinder chamber 18 produce promotes slip spider 7 counter motions.Slip spider 7 drives slips 8 and moves towards the direction away from drilling rod, unclamps drilling rod.
