Abstract
The utility model relates to a tool for lifting a transmission line tower, in particular to a device for lifting a guyed tower in an integrally assembled mode. The device comprises two I-steel beams which are parallelly arranged and buckled with each other, wherein welding plates are welded between the two I-steel beams in a clamping mode; the two ends of each welding plate stretch out of the I-steel beams; and shackles are fixedly arranged at the two ends of each welding plate and connected with steel wire ropes. The two parallel I-steel beams are welded together through a plurality of welding plates which are arranged at intervals, so that the stress points of a balance pulley for lifting can be moved to two sides during lifting, the axial pressure of a cross arm during lifting is reduced, the risk that the cross arm is broken during integral lifting is reduced, balance in the integral lifting process is fully ensured, and lifting safety is ensured.
Description
Technical field
The utility model relates to the Work tool of electric power line pole tower lifting usefulness, is specifically related to crane integral assembly Guywire tower lifting appliance.
Background technology
LV40 tower overall height 43.5m ~ 49.5m, full tower net weight 25.4t ~ 26.9t belongs to high large-scale heavy tower, and conventional method is to adopt herringbone holding pole or the vertical mode of minute system of solutions to construct in the vertical process of group.Because Work tool is stressed very large, there is potential safety hazard in whole group tower scheme; Adopt minute system of solutions vertical, because the double tower body, whole stability is more difficult guaranteed.
Summary of the invention
The purpose of this utility model is to solve the technical matters of above-mentioned existence, and a kind of balance that improves whole lifting in the lifting process is provided, and guarantees the crane integral assembly Guywire tower lifting appliance of the safety of lifting.
To achieve these goals, the crane integral assembly Guywire tower lifting appliance that the utility model provides, comprise two steel I-beams that be arranged in parallel and mutually fasten, the interval is welded with welded plate between described two steel I-beams, steel I-beam is all stretched out at the two ends of described welded plate, the two ends of welded plate are fixed with respectively shackle, described unload to buckle be connected with steel rope.
The end that described welded plate stretches out two steel I-beams is respectively equipped with perforate, and bearing pin is installed in the perforate, and described shackle is welded on the bearing pin two ends.
The utility model welds two parallel steel I-beams together by the welded plate that a plurality of intervals arrange, can be with the stress point of balanced pulley of lifting usefulness more to two side shiftings during lifting, the longitudinal pressure of the cross-arm when reducing to lift by crane, the risk that cross-arm fractures when reducing integral lifting, guarantee fully the balance of whole lifting in the lifting process, guaranteed the safety of lifting.
Show by test, the utility model adopts two parallel steel I-beams, in LV40 type hoisting tower pole process, the situation that does not occur tilting and significantly rock, the situation of also being rolled over without the LV40 cross-arm, guaranteed the quality of LV40 type tower, strengthened the safety in the whole work progress, guaranteed to construct and carry out smoothly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to view;
Among the figure: the 1-steel I-beam; The 2-welded plate; The 3-shackle; The 4-bearing pin; The 5-steel rope.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
As depicted in figs. 1 and 2, crane integral assembly Guywire tower lifting appliance comprises two steel I-beams 1 that be arranged in parallel and mutually fasten, the interval is welded with welded plate 2 between two steel I-beams 1, steel I-beam 1 is all stretched out at the two ends of welded plate 2, the two ends of welded plate 2 are fixed with respectively shackle 3, are connected with steel rope 5 in the shackle 3.
The end that welded plate 2 stretches out two steel I-beams 1 is respectively equipped with perforate, and bearing pin 4 is installed in the perforate, and shackle 3 is welded on bearing pin 4 two ends.
During use, crane is arranged in steel tower tower head direction, suspension hook naturally droops directly over the face of steel tower backguy hanging point place, and the suspension hook below is some rope system.Just crane principal arm and the arm width of cloth remain unchanged immediately, cross the suspension hook that hoisting cable 5 connects, and steel tower is slowly detached ground.At tower leg special-purpose pin holder is set, column foot and ground are isolated, both protected the tower material, prevent that also ground from being hauled out groove by column foot, protection of the environment.After tower leg is liftoff, reduce the arm width of cloth by the principal arm brachium that shortens crane, move to iron tower horizontal directly over the basis after, slowly descend hook to be about to steel tower in place to the basis, install again four steel tower backguys of steel tower, namely finish the group tower.Adopt lifting appliance of the present utility model, the required arm width of cloth of crane is minimum, uses the crane of less tonnage just can satisfy construction requirement, has controlled the lease expenses of crane.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Can be another sidewall of casing 1 such as baffle plate 1.2, this type of is revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, and then the utility model also is intended to comprise these changes and modification interior.
The content that is not described in detail in this specification sheets belongs to the known prior art of this area professional and technical personnel.
