Description

Technical Field

[0001] This invention belongs to the field of track adjustment technology, and in particular relates to a track adjuster for the construction of embedded track systems in urban rail transit. Background Technology

[0002] A track adjuster is a device used in urban rail transit construction to adjust the spacing of embedded tracks to achieve a suitable distance. It assists in the pre-laying of embedded tracks. Traditional track adjusters include a crossbeam with rail-oriented supports at both ends and elevation screws near the ends. Two sliding blocks are mounted on the crossbeam, and adjusting rods are positioned between the sliding blocks and the crossbeam. Each adjusting rod has two adjusting screws with opposite rotation directions at both ends. Flat plates or wedges are provided between the sliding blocks and the top and bottom of the crossbeam. While these devices are simple in structure, easy to use, and offer high adjustment accuracy, they are inconvenient for determining the track spacing for precise positioning during installation and adjustment. Furthermore, the connection point with the track is often located in a pre-embedded groove after installation, affecting the secure connection of the track. Summary of the Invention

Movable seats 8 are inserted into both the left and right sides of the rear of the sliding seat 1. Operating clamping and fixing seat structures 9 are supported on both the left and right sides inside the sliding seat 1. A measuring movable display seat structure 10 is supported at the upper end of the sliding seat 1.

[0021] As attached Figure 2 As shown in the above embodiment, specifically, the operating clamping and fixing seat structure 9 includes a hanging seat 91, with a movable seat 8 bolted to the rear end of the hanging seat 91; rotating gears 92 are axially connected to the left and right sides of the inner side of the hanging seat 91; a clamping head 96 is welded to the lower end of the rotating gear 92; a support screw 93 is threaded to the front end of the hanging seat 91, and an operating end 94 is welded to the front end of the support screw 93; an operating connection bracket structure 95 is supported at the upper end of the hanging seat 91.

[0022] As attached Figure 3 As shown in the above embodiment, specifically, the operation connection bracket structure 95 includes a rotating shaft 951, with an anti-slip disc 952 bolted to the upper end of the rotating shaft 951; a worm gear 953 is welded to the lower end of the rotating shaft 951; turning the anti-slip disc 952 causes the rotating shaft 951 and the worm gear 953 to rotate, thereby cooperating with the rotating gear 92 to clamp and fix the track with the clamping head 96.

[0023] As attached Figure 4 As shown in the above embodiment, specifically, the measurement display seat structure 10 includes a gantry frame 101, with a level 102 bolted to the upper end of the gantry frame 101; a long ruler plate 103 is bolted to the upper part of the inner wall of the gantry frame 101; movable measuring seats 104 are sleeved on both the left and right sides of the outer side of the long ruler plate 103; the bolts inside the rear support plate 5 are turned according to the scale of the long ruler plate 103 to drive the movable seat 8, the hanging seat 91 and the movable measuring seat 104 to move, and the track spacing is precisely adjusted by the scale.

[0024] In the above embodiments, specifically, the rotating shaft 951 is embedded in the middle part inside the hanging base 91 by a bearing.

[0025] In the above embodiment, specifically, the worm gear 953 on the outer side of the rotating shaft 951 meshes with the rotating gear 92. When the rotating shaft 951 is manually rotated, it drives the rotating gear 92 and the clamping head 96 to rotate to clamp and fix the rail.

[0028] Working principle

[0029] The working principle of this invention is as follows: During the construction of urban rail transit, when adjusting the embedded track, the sliding seat 1 is first supported at the designated position by the supporting screw 6 and the installation cone 7. At the same time, the level 102 is used to keep it stable. Then, the secondary telescopic rod 3 on the inner side of the first support 2 is moved and connected to the ground nail with the second support 4 to realize the support and fixation of the sliding seat 1. At the same time as the initial installation, the hanging seat 91 and clamping head 96 on the lower side of the sliding seat 1 are in the embedded pit. Then, the anti-slip plate 952 is turned to rotate the rotating shaft 951 and the worm gear 953, which in turn cooperates with the rotating gear 92 to clamp and fix the track with the clamping head 96. After clamping, the bolts inside the rear support plate 5 are turned according to the scale of the long ruler 103 to drive the movable seat 8, the hanging seat 91 and the movable seat 104 to move and the track spacing is precisely adjusted according to the scale.
