The left parts of the two groups of threaded rods 105 are both provided with a second nut seat 111 through a threaded sleeve, and the right parts of the two groups of threaded rods 105 are both provided with a first nut seat 106 through a threaded sleeve.

[0027] During implementation, by rotating the two sets of adjustment handles 102 separately and utilizing the rotation of the threads, the two sets of main mounting frames 201 and the two sets of auxiliary mounting frames 202 can be driven to move, thereby achieving the effect of fixing and installing the two sets of rails at the same time, ensuring that the two sets of rails can be laid and fixed in parallel, and the efficiency of laying and fixing is improved without the need for personnel proofreading and adjustment.

[0028] Example 2:

[0029] like Figure 1-4 As shown, based on the first embodiment, the present invention provides a technical solution for a track laying and fixing device for an urban rail: the outer ends of the two groups of second nut seats 111 are respectively fixedly connected to the inner ends of the two groups of adjustment plates 205, and the outer ends of the adjustment plates 205 are provided with multiple groups of adjustment holes 206, and the outer ends of the two groups of connecting plates 207 are provided with fastening bolts 208 through threads.

[0030] like Figure 1-4 As shown, both sets of fastening bolts 208 can be threadedly connected to the multiple sets of adjustment holes 206 , the top end of the front connecting plate 207 is fixedly connected to the left auxiliary mounting frame 202 , and the top end of the rear connecting plate 207 is fixedly connected to the rear main mounting frame 201 .

[0031] like Figure 1-4 As shown, the two sets of adjustment plates 205 are fixedly connected with clips 110 on the left and right sides at both ends, and the left sides at both ends of the front and back ends of the base 101 are provided with clips 109 on the upper and lower sides of the sliding groove 104, and the clips 110 are slidably connected in the clips 109.

[0032] like Figure 1-4 As shown, two groups of limiting grooves 107 are opened at the top of the base 101 , and two groups of limiting blocks 108 are fixedly connected to the bottom ends of the two groups of main mounting frames 201 and the auxiliary mounting frames 202 , and the limiting blocks 108 are all located in the limiting grooves 107 .

[0033] During implementation, by setting up the fixing component 1 and the adjusting component 2, and utilizing the cooperation of the fastening bolts 208 and the adjusting holes 206, the spacing between the rails can be conveniently adjusted according to specific laying requirements. The overall structure is simple, stable, and highly modularized, which can greatly improve the efficiency of urban rail laying and fixing work.

[0034] The advantages of this technical solution in practical applications include but are not limited to the following:

[0035] 1. By rotating the two sets of adjustment handles 102 respectively, the two sets of main mounting frames 201 and the two sets of auxiliary mounting frames 202 are driven to move, thereby achieving the effect of fixing and installing the two sets of tracks at the same time, ensuring that the two sets of tracks can be laid and fixed in parallel, without the need for personnel proofreading and adjustment, and improving the efficiency of laying and fixing.

[0036] 2. By cooperating with the fastening bolts 208 and the adjustment holes 206, the spacing between the rails can be conveniently adjusted according to specific laying requirements. The overall structure is simple, stable and highly modularized, which can greatly improve the efficiency of urban rail laying and fixing work.

[0037] This technical solution installs the base 101 through two sets of fixing plates 103. First, rotate the left adjustment handle 102 to drive the rear threaded rod 105 to rotate. The threaded rod 105 simultaneously drives the second nut seat 111 on the left and the first nut seat 106 on the right to move. At this time, the second nut seat 111 drives the rear adjustment plate 205 to move, and the adjustment plate 205 drives the connecting plate 207 to drive the auxiliary mounting frame 202 on the left to move. At the same time, the first nut seat 106 drives the driven rod 204 to drive the main mounting frame 201 on the right to move, completing the adjustment of the track laying position. Then, the two sets of rails are placed on the left auxiliary mounting frame 202 and the right main mounting frame 20 1, at this time, rotating the right adjustment handle 102 drives the front threaded rod 105 to rotate. Similarly to the rear side, the rotation of the front threaded rod 105 will drive the left main mounting frame 201 and the right auxiliary mounting frame 202 to move to the left. At this time, the two sets of main mounting frames 201 and the two sets of auxiliary mounting frames 202 are in contact with each other to clamp the two sets of rails, and further fixed and installed using the mounting holes 203. If it is necessary to adjust the spacing between the rails, the fastening bolts 208 at the front and rear ends of the left side can be rotated respectively to separate them from the adjustment holes 206, so that the positions of the left main mounting frame 201 and the auxiliary mounting frame 202 can be adjusted to the same distance, greatly improving the efficiency of track laying and fixing.
