Description

弯管机 Bender

技术领域 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 technical field of power line construction machinery, in particular to a pipe bending machine.

背景技术 Background technique

[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 the construction of power lines often encounter difficult or even impossible in case of disorder of movement of the building, then a need for a carrier by means of a curved tube as a guide line, whereby the bending machine the long straight pipe bend.

[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 can be seen in China have been disclosed in the patent literature, such as CN2923087Y recommend the "vertical bending machine", which, although having a bending machine specification page 2, lines 8-9 the referred advantages, but there is a lack: First, since its power source is a hydraulic cylinder, and therefore be equipped with hydraulic station, so as to bring trouble to the operation; Second, a high probability of failure, since the hydraulic hose connected to the hydraulic cylinder equipped spliced ​​area prone to leakage, easy to aging and hydraulic tubing, replacement and maintenance inconvenience; Third, since the blank will bend flattened blank during molding to bend the bending i.e. produce off collapse phenomenon, it is necessary to bend the blank i.e. the filler is filled within the lumen of sand (specification page 3, line 19), and the need to clear the lumen was filled after bending, thereby resulting in low efficiency, 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。 In view of the lack of these, so that the patent can not be used in a power scheme 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 with a "vertical bending machine", which patent CN2923087Y lack of presence of the same program.

[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] Further, Publication No. CN1626294A discloses a bending machine and Announcement Publication No. CN100581674C benders defects due to a complicated structure as to facilitate power without accompanying mechanical construction works.

[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 disclosed the "bender", which patent program uses the wheel pipe and with a movable arm reciprocation of the rod (swing), by a ratchet mechanism articulated arm lever (ratchet pawl configuration) so that the principle of leverage using the lever arm pivot and the hinge shaft through the ratchet pawl acting on the control wheel is rotated to an elbow shaped tube. 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 patent is to ensure that the program does not fall off the elbow, and in that the bending process is lengthy insufficient, and only suitable for small diameter and the wall thickness is 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。 Further, the interpretation of the text of the patent specification, since it is one kind of manual operation of the bending machine, and therefore not suitable for use as a power bender construction machine.

[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。 Premise [0006] In view of the above prior art, it is necessary to be improved, made a positive and beneficial to the applicant designed for this, and has taken strict security measures in the applicant for the plant provided by the power sector drawing a tube bending test, the results proved to be feasible, as will be described aspect in this context is generated.
