Technical Field
[0001] The utility model relates to the technical field of rail transit construction, and in particular to a rail transit line support frame. Background Art
[0002] Rail transit usually refers to the subway transportation system, which is a common mode of transportation for people's daily travel. During the construction of the subway, a concrete foundation is laid at the bottom of the tunnel, and the rails are fixed to the concrete foundation through special support frames.
[0003] However, there are certain problems in the process of laying rails. During the laying process, adjacent rails need to be aligned so that the first positions of adjacent rails are aligned. In this way, some fine-tuning is inevitably required after the rails are fixed on the mounting base. However, in order to prevent the rails from loosening, the rails are fixed directly through special mounting bases, and the mounting bases are fixed to the concrete base with bolts to ensure that they will not loosen under the vibration of the subway car. In this way, the rails need to be released from the new mounting bases and installed again after fine-tuning. This will form a huge workload in actual use, increase the labor intensity of the staff, and multiple installation and disassembly of the mounting bases will also reduce their service life.
[0004] Therefore, it is necessary to provide a new rail transit line support frame to solve the above technical problems. Utility Model Content

The four limit rods are divided into a rectangular array, and the bottom ends of the four limit rods respectively pass through the two partitions and are slidably connected with them.
[0008] Preferably, a bidirectional screw is rotatably installed on the inner walls on both sides of the control box, and two transverse plates are slidably installed in the control box.

The rail transit line support frame includes: a support base 1 and a control box 2 fixedly installed on the top of the support base 1. As shown in Figure 1 , four bolts are movably installed on the support base 1. During actual use, the support base 1 is fixedly installed on the ground through the four bolts. A lifting plate 3 is movably installed above the control box 2, and a clamping bin 4 is movably installed on the top of the lifting plate 3. The top of the control box 2 is provided with an opening.

[0023] The tops of the two transverse plates 8 are fixedly installed with a first hinge seat 9, and the two transverse plates 8 are respectively located on the two sections of the bidirectional screw 7 with opposite rotation directions. The bottom of the lifting plate 3 is fixedly installed with two second hinge seats 10, and the two second hinge seats 10 are both close to the middle of the lifting plate 3.

The two embedded blocks 13 are slidably connected to the inner walls of the two limit grooves 12 respectively. In order to prevent the clamping bin 4 from separating from the lifting plate 3 and provide stable limit sliding adjustment, the limit grooves 12 and the embedded blocks 13 are both designed as "T"-shaped embedded blocks. Figure 3 As shown, the top of the lifting plate 3 is rotatably mounted with a threaded rod 15, and the bottom of the clamping bin 4 is fixedly mounted with a transmission block 16, and the threaded rod 15 is threadedly connected to the transmission block 16.

[0027] The working principle of the rail transit line support frame provided by the utility model is as follows:
[0028] During the laying of rail transit lines, workers can first install multiple support seats 1 on the concrete foundation surface before locking the rails through the mounting seats. The installation trajectory is the same as the rail trajectory, and the rails are first placed in multiple clamping compartments 4, and the clamping plate 17 is adjusted by rotating the adjusting rod 18. When the adjusting rod 18 rotates, the clamping plate 17 and the adjusting rod 18 are kept in rotation by the rotating bearing 21. At the same time, under the effect of limiting, the adjusting rod 18 will drive the clamping plate 17 to move horizontally after rotation, thereby fixing the rails in the clamping compartment 4.
[0029] When fine adjustment is required between adjacent rails, the staff can do it by rotating the bidirectional screw rod 7 and the threaded rod 15.
[0030] When the height of the rail needs to be adjusted, the staff can rotate the two-way screw rod 7. The rotation of the two-way screw rod 7 will drive the two transverse plates 8 to move closer to or away from each other. When the two transverse plates 8 move closer to each other, the two first hinge seats 9 will move closer to each other, thereby bringing the bottom ends of the two hinged plates 11 closer. At this time, since the lifting plate 3 is limited by the four limit rods 6, the two hinged plates 11 will gradually tend to be vertical, thereby gradually raising the lifting plate 3. Conversely, when the two-way screw rod 7 is rotated in the opposite direction to move the two transverse plates 8 away from each other, the lifting plate 3 will be driven to move gradually downward, thereby adjusting the height of the rail.
[0031] When the rail needs to be fine-tuned in the horizontal direction, the staff only needs to rotate the threaded rod 15. The forward and reverse rotation of the threaded rod 15 will drive the transmission block 16 to move left and right, thereby driving the clamping chamber 4 to move left and right, thereby adjusting the horizontal direction of the rail.
[0032] After completing the level and height adjustment, the multiple support seats 1 supporting the rails are adjusted accordingly to keep the rails at the same height, and then the rails are released from the clamping compartment 4, and the mounting seats are locked, and then the support seats 1 can be removed.
[0033] Compared with related technologies, the rail transit line support frame provided by the present invention has the following beneficial effects:
[0034] The utility model provides a rail transit line support frame. When laying rails in rail transit, the adjusting rod 18 is first rotated to drive the clamping plate 17 to move horizontally, so that the rails can be clamped quickly. At the same time, after the rails are clamped, the horizontal direction and height of the rails can be adjusted by rotating the bidirectional screw rod 7 and the threaded rod 15. After the adjustment is completed, the rails are locked by the mounting seat. The whole process is simple to operate, and the process of repeatedly disassembling the mounting seat is reduced, thereby improving the efficiency of line laying and reducing the labor intensity of the staff.
