Description

Technical Field

[0001] This utility model relates to the field of urban rail technology, specifically to a hydraulic switch machine for urban rail. Background Technology

[0002] Currently, most hydraulic switch machines rely on hydraulic power to drive the main and auxiliary turnouts. The connecting oil pipes between the main and auxiliary turnouts in the hydraulic transmission system are the main components of the transmission system. The hydraulic switch machine fixes the upper surface of the concrete sleeper by installing a support plate. However, due to the settlement of the concrete sleeper over a long period of use, the height of the road to the concrete sleeper will be uneven, making it difficult to adjust the level of the hydraulic switch machine after installation, which affects the installation and use of the hydraulic switch machine. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a hydraulic switch machine for urban rail transit, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic switch machine for urban rail transit, comprising a switch machine, with second fixed blocks fixedly connected to both sides of the switch machine, a first fixed block placed at the bottom of each of the second fixed blocks, a telescopic column fixedly connected to the bottom of each of the first fixed blocks, a guide block fixedly connected to the bottom end of each telescopic column, a fixed box movably fitted on the outer side of each guide block, several slots opened on the surface of each telescopic column, a first bolt inserted into one side of each fixed box, one end of each first bolt passing through a corresponding slot and extending to the outer side of each fixed box, and a first nut threadedly connected to the outer side of one end of each first bolt; the switch machine is model ZYJ7.

[0005] Preferably, mounting bases are placed on both sides of the switch machine, and the bottom of the fixed box is fixedly connected to the top of the corresponding mounting base.

[0006] Preferably, mounting components are fixedly connected to both the front and rear ends of the mounting base.

[0007] Preferably, a second bolt is inserted inside each of the second fixing blocks.

[0008] Preferably, the bottom end of the second bolt passes through the second fixing block and the first fixing block and extends to the bottom of the first fixing block.

[0009] Preferably, a second nut is threaded onto the outer side of the bottom end of the second bolt.

[0010] This utility model provides a hydraulic switch machine for urban rail transit, which has the following advantages:

[0011] 1. This urban rail hydraulic switch machine, equipped with a fixed box, mounting base, and mounting components, involves unscrewing the first nut from the outside of the first bolt, then moving the first bolt out of the slot and fixed box, lowering the fixed box, adjusting the position of the mounting base, and then, after adjusting the position of the mounting base, passing one end of the first bolt through the slot and out to the outside of the fixed box. The first nut is then screwed onto the outside of the first bolt to fix the positions of the telescopic column, the fixed box, the mounting base, and the mounting components, thereby adjusting the height of the mounting base and ultimately adjusting the level of the switch machine.

[0012] 2. This urban rail hydraulic switch machine, by setting a second fixed block, a first fixed block and a second bolt, places the mounting base below the second fixed block, so that the first fixed block is below the second fixed block. Then, the bottom end of the second bolt passes through the second fixed block and the first fixed block and extends to the bottom of the first fixed block. Then, the second nut is screwed to the outside of the second bolt to limit and fix the position of the second fixed block and the first fixed block, and connects the switch machine to the fixed box and the mounting base.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1

[0019] Please see Figures 1 to 3This utility model provides a technical solution: a hydraulic switch machine for urban rail transit, including a switch machine 1. Second fixing blocks 11 are fixedly connected to both sides of the switch machine 1. First fixing blocks 10 are placed at the bottom of each of the second fixing blocks 11. Telescopic columns 6 are fixedly connected to the bottom of each of the first fixing blocks 10. Guide blocks 14 are fixedly connected to the bottom ends of each telescopic column 6. A fixed box 5 is movably fitted onto the outer side of each guide block 14. Several slots 9 are opened on the surface of each telescopic column 6. First bolts 7 are inserted into one side of each fixed box 5. One end of each first bolt 7 passes through a corresponding slot 9 and extends to the outer side of the fixed box 5. A first nut 8 is threaded onto the outer side of one end of each first bolt 7.

[0020] Mounting bases 4 are placed on both sides of the switch machine 1. The bottom of the fixing box 5 is fixedly connected to the top of the corresponding mounting base 4, and the height of the mounting base 4 is adjusted by the fixing box 5.
