Description

Technical Field

[0001] The utility model relates to the technical field of rail clamps, in particular to a track adjustable lateral force resisting rail clamp. Background Art

[0002] The rail clamp is also called a welded rail clamp, a welded rail fixing device, a steel beam rail clamp, and a welded pressure plate. Its function is to clamp and fix the rails. It is usually welded to an I-beam and sometimes used on a steel plate pre-embedded in concrete. By compacting the track, the rail clamp can improve the stability and smoothness of the railway line, thereby ensuring the safety and efficiency of railway transportation. As people pay more and more attention to track safety, the rail clamp not only needs to be able to resist the pressure from the vertical direction, but also needs to resist the lateral pressure of the rails.

[0003] The prior art discloses a track adjustable anti-lateral force rail clamp with publication number: CN217323080U. It includes a track foundation, in which a fixing bolt is pre-set at the position corresponding to both sides of the track; a pressure plate is sleeved on the fixing bolt; a sleeve matching the fixing bolt is screwed on the pressure plate; a pressure rod is arranged on the outer surface of the sleeve matching the fixing bolt; a thread is arranged on the free end of the pressure rod; and a sleeve matching the pressure rod is screwed on the free end of the pressure rod. The utility model solves the problem of lateral slippage of the track subjected to lateral force, and allows the track position to be adjusted, and solves the problem of track deformation due to certain reasons that requires track adjustment, and has the characteristics of simple structure, convenient construction, high construction efficiency, low cost, and easy maintenance and replacement of the track.

[0004] When the utility model is in use, the track is pressed and tightened in the vertical direction by the provided pressure plate, and then the side web of the track is pressed and tightened by the pressure rod and the threaded sleeve. The two are independent of each other, and the contact area between the pressure plate, the threaded sleeve and the track is relatively narrow. Therefore, when they are subjected to vertical force and lateral force from the track, the pressure per unit area of ​​the two components is relatively large, which makes it easy to bend, deform and damage. In addition, an elliptical hole is provided on the pressure plate, and when the pressure plate is subjected to lateral force, a certain degree of lateral sliding is prone to occur, thereby reducing the reliability of the use of an adjustable track anti-lateral force rail clamp.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an adjustable track anti-lateral force rail clamp, which has the following beneficial effects:

[0016] (1) The utility model is provided with a pressure plate, a tightening plate, a first anti-loosening wedge block and a second anti-loosening wedge block. The top surface of the track foundation is provided with a secondary casting layer, and a steel rail is installed in the center of the top surface of the secondary casting layer. The track foundation and the secondary casting layer are symmetrically embedded with fixing bolts. During installation, the worker can correspondingly sleeve the mounting blocks symmetrically welded on one side of the mounting plate on the fixing bolts, and install and fix them through gaskets and fastening nuts. At this time, the limit block fixedly installed on the bottom surface of the mounting plate is inserted into the secondary casting layer. The fixing installation of the mounting plate can be completed in the limit card slot opened on the layer. The mounting plate is provided with a guide slot, and a pressure plate is embedded in the guide slot. The pressure plate is pushed to move along the guide slot until one end of the bottom surface of the pressure plate abuts against the top surface of the lower edge of the rail, and at the same time, the side pressure block welded on the bottom surface of the mounting plate abuts against the side wall of the lower edge of the rail. Finally, the worker can rotate the tightening screw sleeved in the threaded sleeve, because one end of the tightening screw is connected to the first anti-loosening wedge block, and one side of the first anti-loosening wedge block is fixedly installed. The first anti-loosening wedge block and the second anti-loosening wedge block are fixedly mounted on the top surface of the pressure plate, and the first anti-loosening wedge block and the second anti-loosening wedge block are fixedly mounted on the top surface of the pressure plate, so that the first anti-loosening wedge block and the anti-loosening wedge block can be pushed to move along the guide sliding rod direction with the rotation of the tightening screw until the anti-skid rubber pad fixedly mounted on one side of the anti-loosening plate abuts against the side wall of the web of the rail. At the same time, the lower inclined surface of the first anti-loosening wedge block abuts against the upper inclined surface of the second anti-loosening wedge block fixedly mounted on the top surface of the pressure plate. The mutual abutment and limiting effect of the blocks can enable the pressure plate to resist the force in the vertical direction and the abutment plate and the side pressure block to resist the force in the lateral direction. Since the contact area between the pressure plate, the abutment plate and the side pressure block and the rail is larger, and a buffer spring is connected and installed between the first anti-loosening wedge block and the mounting plate, it can be more stable when subjected to the impact force from the rail and is not prone to deformation and damage. At the same time, the pressure plate is not prone to side sliding, so it is safer, more reliable and more practical to use.

[0017] (2) The utility model is provided with a trigger block and a pressure sensor. The trigger block is symmetrically welded on the top surface of the pressure plate, and the side wall of the mounting plate is installed with the pressure sensor. When the pressure plate fails and becomes loose after long-term use, the pressure plate slides outward along the guide groove to drive the trigger block to move, thereby causing the trigger block to press the pressure sensor. By connecting the pressure sensor to the background alarm device, an alarm can be promptly sent to the background when the adjustable anti-lateral force rail clamp fails, thereby reminding the staff to rush to the scene in time for processing, thereby ensuring the normal and safe use of the rails, and being more practical.
