Abstract
A hanging cable pulley overhauling device of a large bridge crane comprises a hanging beam, a jackscrew is arranged on the hanging beam, limiting holes are formed in the two ends of the hanging beam respectively, hanging arms are installed in the limiting holes, a plurality of regulating holes are formed in the upper end of each hanging arm, the lower ends of the hanging arms bend inward to be in the shape of a hook, two clamping and locating plates are symmetrically arranged in the middle of the lower surface of the hanging beam, and the two clamping and locating plates are matched with locating grooves formed in the lower surface of the hanging beam. Due to the fact that the limiting holes are formed in the hanging beam and the regulating holes are formed in the hanging arms, the left-and-right positions and the vertical positions of the hanging arms can be flexibly regulated, and thus the hanging arm length requirements of brackets with different sizes can be met. Meanwhile, the hanging cable pulley overhauling device of the large bridge crane has the advantages of being easy to install and steady to use.
Description
Technical field
The utility model relates to field of iron and steel smelting, refers to particularly a kind of large bridge crane lashed cable coaster maintenance device.
Background technology
On crane in bridge type, the power cable on dolly and the moving part of actuating cable generally are called lashed cable.During carriage walking, lashed cable is suspended on the I-beam section crossbeam by carriage, hangs and relies on the coaster at carriage top to be connected with the I-beam section crossbeam.In the routine use process, the pulley of coaster also there will be wheel wear, and bearing is damaged, and the problems such as coaster sideslip must be adjusted coaster or change pulley.the small-scale bridge hoisting crane due to the lashed cable holder and carriage little, lightweight, process these problems and there is no much difficulty, but for the large bridge crane as more than 100t, the weight of dolly lashed cable and carriage is up to the hundreds of kilogram, adjust coaster or change the pulley difficulty very large, general use and maintenance hoist ceiling crane or guide chain are sling lashed cable and carriage, make pulley break away from the I-beam section crossbeam, could adjust coaster or change pulley, do like this restriction that is subject to the condition of overhauling, such as whether parking stall has the maintenance hoist ceiling crane, the suspension of guide chain needs the factory building top that girder steel etc. is arranged, maintenance is inconvenience very.Therefore, need a kind of maintenance device of special use badly, be used for the lashed cable of large bridge crane is raised together with carriage, make the pulley of coaster break away from the I-beam section crossbeam.
Summary of the invention
The purpose of this utility model will provide a kind of safe, easy large bridge crane lashed cable coaster maintenance device exactly, the repair and maintenance that is used for large bridge crane lashed cable coaster, solve in the process of maintenance lashed cable coaster on large bridge crane and cause the inconvenience that coaster can't dismounting, while adjusting, use and maintenance hoist ceiling crane or guide chain are brought because the weight of lashed cable and carriage is excessive, make maintenance not be subjected to the restriction of site environment.
For achieving the above object, a kind of large bridge crane lashed cable coaster maintenance device that the utility model is designed, comprise hanging beam, be provided with jackscrew above described hanging beam, its special character is, the two ends of described hanging beam are respectively equipped with spacing hole, in described spacing hole, upper arm is installed, the upper end of described upper arm is provided with a plurality of adjustment holes, the lower end of described upper arm bends inwards and is hook-shaped, the following centre of described hanging beam is arranged with two blocks of clamping position plates, and described two blocks of clamping position plates match with the positioning groove that hanging beam arranges below.
As preferred version, described clamping position plate is bolted on below hanging beam.
Further, described upper arm is bolted on hanging beam.
Further, the quantity of described adjustment hole is 3 ~ 8.
The utility model has the advantage of: by spacing hole being set and in the upper arm upper end, adjustment hole being set on hanging beam, realize the left and right of upper arm, the flexible of upper-lower position, thereby meet the requirement of different large Small brackets to upper arm length, the utility model also has advantages of that installation is simple, it is firm to use simultaneously.
Description of drawings
Fig. 1 is a kind of structural representation of large bridge crane lashed cable coaster maintenance device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of large bridge crane lashed cable coaster maintenance device that the utility model is designed, comprise hanging beam 1, be provided with jackscrew 2 above hanging beam 1, the two ends of hanging beam 1 are respectively equipped with spacing hole 6, and upper arm 4 is installed in spacing hole 6, the upper end of upper arm 4 is provided with a plurality of adjustment holes 5, the lower end of upper arm 4 bends inwards and is hook-shaped, and the following centre of hanging beam 1 is arranged with 3, two blocks of clamping position plates 3 of two blocks of clamping position plates and matches with the positioning groove 7 that hanging beam arranges below.In addition, clamping position plate 3 is bolted on below hanging beam 1, and upper arm 4 is bolted on hanging beam 1, and the quantity of adjustment hole 5 is 3 ~ 8.
During use, according to the position of institute's maintenance coaster, the installation and repairing device; Fixedly hanging beam 1, and hanging beam 1 is fixing by clamping position plate 3 location perpendicular to the I-beam section crossbeam; Upper arm 4 is installed, and upper arm 4 lower ends will tangle the carriage both side ends, and upper arm 4 tops are connected with hanging beam,, according to the size of on-the-spot carriage, regulate the length of upper arm 4 by regulating adjustment hole 5 positions; Lift carriage, the jackscrew 2 by in the middle of rotation hanging beam 1, lift carriage, and the coaster wheel is in unsettled situation and gets final product; Implement maintenance, after the coaster wheel is unsettled, can overhauls and change; After having overhauled, remove the maintenance device; Aforesaid operations two maintenance workers can complete.
Apply 17 above crane in bridge type of 100t of Wuhan Iron and Steel Plant steel-making head factory three subsidiary factory of the present utility model, comprising 7 450t: before using the utility model, when maintenance lashed cable coaster fault, crane in bridge type must be parked in fixing maintenance zone, use hoist ceiling crane or guide chain, with the interference that often makes a difference of other overhauling project, on across other crane in bridge type and on-the-spot normal production, bringing impact.After using the utility model, above problem is resolved, can not be subject to the restriction of the condition of overhauling when maintenance lashed cable coaster fault, can not have influence on the normal operation of other overhauling project and other crane in bridge type yet, simultaneously, the efficiency of maintenance also is improved, and the repair time shortens 30%, reduces service personnel 1-2 people.
