弯管机 Bender

技术领域 Technical Field

[0001] 本发明属于电力线路施工机械技术领域,具体涉及一种弯管机。 [0001] The present invention belongs to the field of power line construction machinery and technology, in particular to a bender.

背景技术 Background

[0002] 如业界所知,在电力线路施工中通常会遇到难以甚至根本不可能移动的建筑物的障碍的情形,于是需要借助于弯曲的管子作为导引线路的载体,从而由弯管机将直长的管子弯曲。 [0002] As known in the industry, in power line construction in difficult situations commonly encountered obstacles even impossible to move the building, then need the help of a curved tube as a guide line carrier so the bending machine The straight length of pipe bending.

[0003] 关于弯管机的技术信息可在已公开的中国专利文献中见诸,如CN2923087Y推荐有“立式弯管机”,这种弯管机虽然具有说明书第2页第8-9行著称之长处,但是存在以下欠缺:其一,由于其动力源为液压缸,因而需配备液压站,从而给操作带来麻烦;其二,故障几率高,因为与液压缸连接的液压油管在配接部位容易出现泄漏,并且液压油管易老化,更换与维护不便;其三,由于弯管上模压向弯管坯时会将弯管坯压瘪即产生塌折现象,因此需要向弯管坯的管腔内填入填充物即细沙(说明书第3页第19行),并且在弯曲成形后又需将填充物清出管腔,由此而造成工作效率低下,电力施工作业人员劳动强度大。 [0003] technical information about the bending machine disclosed in the patent literature seen in China, such as CN2923087Y recommend the "vertical bending machine," which bender while having instructions page 2, lines 8-9 the commonly known strengths, but the lack of presence of the following: First, because of its power source for the hydraulic cylinders, and thus be equipped with hydraulic stations, and thus to operate trouble; secondly, the failure probability is high, because the hydraulic hose connected to the hydraulic cylinder equipped the spots prone to leakage and hydraulic tubing easy to aging, replacement and maintenance of inconvenience; Third, since the blank will bend flattened blank during molding to bend the elbow which produce collapse fold and, therefore, need to bend blank That filled lumen filler sand (instructions on page 3, line 19), and then bending the filler need to clear the lumen, thus resulting in inefficiency, large power construction workers labor intensity . 鉴于这些欠缺,使该专利方案不能在电力施工现场使用。 Given the lack of programs so that the patent can not be used in power construction site. CN200995238Y提供有“立式弯管机”,该专利方案同样存在CN2923087Y的欠缺。 CN200995238Y provided "vertical bender", the program also exists CN2923087Y patent lack.

[0004] 又,公开号CN1626294A公开的弯管机以及公告号CN100581674C公告的弯管机由于存在结构复杂的缺憾而不便于作为电力施工作业中的随行机械。 [0004] Also, Publication No. CN1626294A disclosed benders and Announcement Notice No. CN100581674C benders because of the complex structure of defects and not easy to work in construction as the power accompanying machinery.

[0005] 及,CN2827577Y披露有“弯管机”,该专利方案采用可移动的管轮体并且利用力臂杆的往复运动(摆动),通过与力臂杆铰接的棘轮机构(棘轮与棘爪构成)利用杠杆原理使力臂杆利用铰轴支点并通过棘爪作用于棘轮,控制管轮转动至弯管成型。 [0005] and, CN2827577Y disclose "bender", which patent program uses a movable tubular body and the use of the wheel arm lever reciprocates (swings), the lever arm with the articulated ratchet mechanism (ratchet and pawl constitute) the use of leverage to make use of the lever arm pivot hinge and by acting on the ratchet pawl control tube to bend wheel rotation molding. 该专利方案的长处在于保证弯管不塌折,而不足在于弯管过程冗长,并且只能适合于小口径的并且壁厚相对较薄的水暖管子。 Advantage of this program is to ensure that the patent does not fall off the elbow, but not enough that the elbow lengthy process, and only suitable for small diameter and wall thickness of the relatively thin plumbing pipe. 此外,通过该专利的说明书全文的解读,由于其是一种手工操作的弯管机,因此并不适宜作为电力施工机械的弯管机使用。 In addition, through the interpretation of the specification of the patent, because it is a manually operated bender, therefore, not suitable as a power construction machinery bender use.

[0006] 鉴于上述已有技术,有必要加以改进,为此本申请人作了积极而有益的设计,并且在采取了严格的保密措施的前提下,在本申请人厂区对由电力部门提供的管件图纸进行了弯折试验,结果证明是切实可行的,下面将要介绍的技术方案便是在这种背景下产生的。 Under the [0006] In view of the above prior art, it is necessary to be improved, for which the applicant made a positive and useful design, and the strict security measures taken under the premise of the present applicant supplied by the plant to the electricity sector Drawing for a tube bending test, the results proved to be practical, technical solutions will be introduced in this context is generated.
