Description

Technical Field

[0001] This utility model relates to the field of railway equipment technology, specifically a combined nylon baffle seat. Background Technology

[0002] Nylon baffle seats are fixed to both sides of the concrete sleepers on both sides of the rails, playing an important role in securing the rails and maintaining and adjusting the distance between the two rails.

[0003] A search revealed a patent document CN201721401813.7 that discloses "a trapezoidal nylon baffle seat for railway use," comprising two trapezoidal seats connected together by an extendable and retractable connecting plate at the bottom. The upper end of the connecting plate is used to install the rail. Compared with ordinary nylon baffle seats, it increases the force-bearing area with the concrete sleeper, reduces the impact force of the lateral force generated when the train passes on the rail bearing groove shoulder of the concrete sleeper, and helps to improve the service life of the concrete sleeper and driving safety.

[0004] The current patent uses a simple fixing structure for fixing steel rails, which is not conducive to stable fixing and has low fixing strength. After long-term use, it is easy to loosen and affect normal use. To address this, we propose a combined nylon baffle seat to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to provide a modular nylon baffle seat to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined nylon baffle seat, comprising a concrete sleeper seat and a rail body, wherein a shock-absorbing plate is fixed to the bottom of the rail body, the shock-absorbing plate is disposed on the top of the concrete sleeper seat, and fixing plates are installed on both sides of the top of the concrete sleeper seat corresponding to the rail body by first bolts, and a nylon baffle seat body is installed on one side of the top of the fixing plate by second bolts; a driving mechanism is fixedly installed on the top of the fixing plate and on the side corresponding to the nylon baffle seat body; a locking mechanism for fixing the nylon baffle seat body is fixedly installed on the moving end of the driving mechanism.

[0007] Furthermore, the driving mechanism includes a vertical plate, which is fixedly installed on the top of the fixed plate. Guide rails are symmetrically installed on the right side of the vertical plate. A screw is provided on the left side of the vertical plate. The right end of the screw extends through the outside of the vertical plate and is fixedly connected to a rotating block. A cover sleeve is movably connected to the outside of the rotating block. The outside of the cover sleeve is slidably connected to two guide rails through two guide sliders.

[0008] Furthermore, a rotating handle is fixedly connected to the left end of the screw, and the screw is threadedly connected to the vertical plate.

[0009] Furthermore, the locking mechanism includes a plug-in shell, which is fixedly connected to the right side of the cover sleeve. A vertical rod is fixedly connected between the top and bottom of the inner wall of the plug-in shell. A lifting plate is slidably connected to the vertical rod along the axial direction. A locking plug rod is fixedly connected to the top of the lifting plate. A thrust spring is sleeved on the surface of the vertical rod and below the lifting plate.

[0010] Furthermore, the outer side of the nylon baffle seat body is provided with a slot that is compatible with the plug shell, and the top of the nylon baffle seat body is provided with a locking channel that communicates with the slot at the position corresponding to the locking rod.

[0011] Furthermore, a sealing cover is inserted into the top of the nylon baffle seat body at the position corresponding to the locking channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model utilizes a first bolt to position the fixing plate on the concrete sleeper seat, and a second bolt to initially fix the nylon baffle seat body. Workers can rotate the screw, and through the threaded connection with the vertical plate, the rotating block can be moved towards the side of the rail body. Under the limit of the guide rail and guide slider, the covering sleeve drives the locking mechanism to move inward. After pressing the locking rod downward until the insertion shell is inserted into the slot, the thrust spring pushes the lifting plate upward under the connection of the vertical rod, allowing the locking rod to be inserted into the locking channel for secondary fixing, thus completing the installation. Similarly, during removal, simply press the locking rod down from the top of the locking channel and rotate the screw in the opposite direction to disengage the locking mechanism from the slot. This combined nylon baffle seat has a reasonable structural design and is easy to use. The bolt-fitting installation method greatly improves the installation stability of the nylon baffle seat, and it is not prone to loosening after long-term use, ensuring the normal use of the nylon baffle seat.

A covering sleeve 85 is movably connected to the outside of the rotating block 84. The outside of the covering sleeve 85 is slidably connected to two guide rails 82 via two guide sliders 86. When the screw 83 is rotated, it is threadedly connected to the vertical plate 81, which can drive the rotating block 84 to rotate and move inward. Through the limiting of the guide sliders 86 and the guide rails 82, the rotating block 84 can drive the covering sleeve 85 to translate inward.

[0023] A locking mechanism 9 for fixing the nylon baffle seat body 7 is fixedly installed on the moving end of the drive mechanism 8. The locking mechanism 9 includes a plug shell 91, which is fixedly connected to the right side of the cover sleeve 85. A vertical rod 92 is fixedly connected between the top and bottom of the inner wall of the plug shell 91. A lifting plate 93 is slidably connected to the vertical rod 92 along the axial direction. A locking plug rod 94 is fixedly connected to the top of the lifting plate 93. A thrust spring 95 is sleeved on the surface of the vertical rod 92 and below the lifting plate 93.

[0024] The outer side of the nylon baffle seat body 7 is provided with a slot 10 that is compatible with the plug shell 91.
