The invention aims to solve the defects in the prior art and provides a telescopic device for a track beam.
In order to achieve the purpose, the invention adopts the following technical scheme:
a telescoping device for a track beam, characterized by: including two supports that correspond the setting, every support all includes the mounting panel, mounting panel top symmetry is equipped with two fixing bases, every fixing base upside all is equipped with the spout of vertical setting, all be equipped with the stand in every spout, every stand homoenergetic slides from top to bottom in rather than relative spout, two stand upsides on same support jointly and connect the fixed block, all be equipped with the through-hole in every fixed block one side, sliding fit connects the sliding column in every through-hole, every sliding column all hangs through a set of gallows and connects at the connecting plate downside, still be equipped with the cushion in connecting plate top one side, the cushion sets up in the expansion joint of track roof beam.
Preferably, each sliding groove is a square groove.
Preferably, each upright column is a square column, and the square column and the square groove are correspondingly arranged.
Preferably, each mounting plate is provided with a mounting hole.
Preferably, a group of installation through grooves are uniformly formed in the upper side of the connecting plate.
Preferably, a hanging hole is formed in one side of the hanging frame, and the hanging frame is fixedly sleeved on the outer side of the sliding column through the hanging hole.
The invention has the advantages that: the telescopic device for the track beam is installed and positioned in a vertically split manner, can realize horizontal and vertical telescopic adjustment, relieves moment deformation when a train passes through an expansion joint, and has the advantage of convenience in replacement.

Fig. 1 is a schematic structural view of a telescopic device for a track beam provided by the invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the present invention provides a telescopic device for a track beam, which is characterized in that: including two supports that correspond the setting, two support parallel arrangement, every support all includes mounting panel 1, every all be equipped with four mounting holes 1.1 on the mounting panel 1. Two fixing bases 2 are symmetrically welded and fixed above the mounting plate 1, the upper side of each fixing base 2 is provided with a sliding groove which is vertically arranged, each sliding groove is a square groove, each sliding groove is provided with a stand column 3, each stand column 3 is a square column, and each square column corresponds to the corresponding square groove. Every stand 3 all can slide from top to bottom rather than relative spout, and 3 upsides of two stands on the same support jointly and connect fixed block 4, and fixed block 4 is square piece, all is equipped with the through-hole in 4 one sides of every fixed block, sliding fit connects sliding column 5.3 in every through-hole, and sliding column 5.3 is circular post, and every sliding column 5.3 all hangs through the gallows 5.2 at both ends and connects at connecting plate 5.1 downside, and gallows 5.2 one side is equipped with the lewis hole, gallows 5.2 cup joints through the lewis hole and fixes in the sliding column 5.3 outside. One side above the connecting plate 5.1 is also provided with a cushion block 5.4, and the cushion block 5.4 is arranged in the expansion joint of the track beam. Two installation through grooves 5.5 are uniformly arranged on the upper side of the connecting plate 5.1.
When the expansion joint is used, the connecting plates 5.1 are fixedly arranged on the track beam at the positions of the two through grooves 5.5 through mounting screws, and the cushion blocks 5.4 are arranged in the expansion joint of the track beam. And the mounting plate 1 is fixedly mounted on a base plate below the track beam through mounting screws at the four mounting holes 1.1. When the train passes through the expansion joint, can produce vertical decurrent pressure and forward thrust to the track roof beam, vertical decurrent pressure reciprocates along the spout through stand 3 and alleviates, and forward thrust is alleviated along the through-hole reciprocating sliding of fixed block 4 through sliding column 5.3.
