Background technology

During bridge construction, need to make the box beam of bridge fabrication machine move by travelling bridge, and hanger adds box beam Weight usually all weigh hundreds of tons, need larger driving force to be driven, existing solution be using oil cylinder to hanging Frame is pushed, but oil cylinder once can only push hanger to move a small distance, is required for manually going to take out after pushing each time Bolt is pushed next time again after so that oil cylinder is moved forward, and this mode for pushing hanger is time-consuming and laborious, has seriously affected and has made The efficiency of bridge engineering.

Utility model content

The purpose of this utility model is to provide a kind of mechanisms of driving hanger movement, to solve the above problems.

The utility model provides a kind of mechanism of driving hanger movement, including hydraulic cylinder, piston shoes and guide rail, the hydraulic pressure One end of oil cylinder connects the hanger, and the other end connects the piston shoes, and the guide rail is located on bridge floor, the hydraulic cylinder, cunning Boots and hanger are arranged on the guide rail, and the guide rail offers multiple limiting slots at equal intervals, is equipped with and uses in the piston shoes It is inserted into the limiting slot in one end of the gag lever post of limitation piston shoes movement, the gag lever post, the both sides of the other end are respectively equipped with One limit hole is inserted with bolt in one of them described limit hole.

Optionally, the more plate muscles for increasing piston shoes intensity are equipped in the piston shoes.

Optionally, the gag lever post is the gag lever post of bottle shape, and the mouth cylindrical part of the gag lever post is inserted into the limiting slot.

Optionally, the guide rail is the guide rail that more piece track is spliced,

The mechanism of driving hanger movement provided by the utility model, is cooperated using gag lever post, limiting slot and bolt, energy Enough Continuous Drive hangers advance without manually going to plug bolt repeatedly, not only save manpower, but also improve the advance of hanger Speed improves the efficiency of bridging engineering.

Specific implementation mode

Below in conjunction with the drawings and specific embodiments to the utility model proposes driving hanger movement mechanism make it is further It is described in detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that Attached drawing is all made of very simplified form and uses non-accurate ratio, only to it is convenient, lucidly aid in illustrating this practicality The purpose of new embodiment.

As described in Figure 1, the mechanism of the driving hanger movement includes：Hydraulic cylinder 2, piston shoes 3 and guide rail 4, the guide rail 4 It is arranged on bridge floor, the hydraulic cylinder 2 and piston shoes 3 are arranged on the guide rail 4, one end connection of the hydraulic cylinder 2 The hanger 1, the other end connect the piston shoes 3, multiple limiting slots 41, the piston shoes 3 are offered at equal intervals on the guide rail 4 Interior to be equipped with gag lever post 31, one end of the gag lever post 31 is inserted into the limiting slot 41, and the both sides of the other end are respectively equipped with one Limit hole is referred to as the first limit hole 32 and the second limit hole 33, it is assumed that hanger 1 is along arrow institute in Fig. 1 for convenience of distinguishing The direction of finger moves, then is inserted into bolt in the first limit hole 32；If hanger 1 is moved along the opposite direction of arrow meaning, Then bolt is inserted into the second limit hole 33.

Referring to FIG. 2, the gag lever post 31 is bottle shape, including mouth cylindrical part 311 and body portion 312, the gag lever post 31 It is inserted into the limiting slot 41, is inserted in limiting slot 41 similar to a bottle, i.e., the mouth cylindrical part 311 of the gag lever post 31 is inserted Enter in limiting slot 41, the diameter in the body portion 312 needs the width more than the limiting slot 41, makes the body portion 312 It can not be inserted into limiting slot 41.

It is now assumed that hanger 1 needs to advance along the direction of arrow meaning, hydraulic cylinder 2 pushes hanger 1 to move forward, at this time Due to reaction force, piston shoes 3 can be rotated by the thrust from hydraulic cylinder 2, gag lever post 31, body portion 312 and be inserted in first Bolt contact in limit hole 32, mouth cylindrical part 311 and the edge of limiting slot 41 are inconsistent, prevent piston shoes 3 from sliding backward, wait for hanger After the completion of 1 movement, hydraulic cylinder 2 is shunk, and piston shoes 3 can be rotated by the pulling force from hydraulic cylinder 2, gag lever post 31, mouth cylindrical part 311 produce limiting slot 41, and gag lever post 31 becomes horizontality, and piston shoes 3 move forward a distance, until gag lever post 31 is inserted into Stop after in next limiting slot 41.Then hydraulic cylinder 2 pushes hanger 1 again, repeats the above steps later, until hanger 1 It is moved to designated position.

The guide rail 4 is spliced by more piece track, and the hydraulic cylinder 2 drives one section of the movement of the hanger 1 every time, so After remove this section track, the track continued access in itself and front is got up, shorter guide rail can be utilized in this way to realize long range Movement.

More plate muscles 34 are additionally provided in the piston shoes 3, the plate muscle 34 can increase the intensity of the piston shoes 3, reduce and slide The risk that boots 3 rupture.

Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belong to right and want Seek the protection domain of book.
