Description

Technical Field

[0001] This utility model belongs to the field of railway maintenance technology, specifically relating to a railway sleeper bolt oiling device. Background Technology

[0002] Railway sleeper bolts are the core connecting components between sleepers and rails in the track structure system, and their connection strength directly determines the overall stability of the track and the safety of train operation. These bolts are exposed to the complex outdoor environment for extended periods, continuously subjected to wind and rain erosion, freeze-thaw cycles, salt and alkali corrosion, and high-frequency vibrations generated by train operation. This makes them highly susceptible to thread corrosion, bolt jamming, and even breakage. This not only significantly increases the difficulty of subsequent bolt disassembly and replacement but also creates safety hazards such as track structure loosening and track deformation. Therefore, regularly applying oil to the sleeper bolts for rust prevention is a crucial procedure in railway daily operation and maintenance.

[0003] Traditional lubrication of railway sleeper bolts is mostly done manually, typically using a brush to apply lubricant or a simple oil can for spraying. This method is inefficient. Given the long length of railway lines and the large number of sleeper bolts, manual lubrication is insufficient to meet the requirements of large-scale, high-efficiency maintenance, especially during the concentrated maintenance phase of mainline railways, which can easily lead to a backlog of maintenance tasks. Utility Model Content

[0004] The purpose of this invention is to provide a railway sleeper bolt oiling device to solve the problems mentioned in the background art, such as the low efficiency of manual bolt oiling and the increased labor intensity of workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a railway sleeper bolt oiling device, comprising a base and a protective plate installed on the surface of the base, wherein two connecting seats are fixed on both outer walls of the base, a positioning frame is fixed on one outer wall of the connecting seat, and a fixing plate is fixed on both outer walls of the positioning frame, a drive motor is installed on the outer wall of one of the fixing plates, and a drive roller rotatably connected to the positioning frame is fixed at the output end of the drive motor;

[0006] A liquid storage tank is installed on the surface of the protective plate. A self-priming pump is installed inside the liquid storage tank. A guide pipe is installed at the outlet of the self-priming pump, and a guide plate is fixed at the bottom of the guide pipe. An oiling pipe is movably connected to the outside of the guide pipe.

[0007] In a further embodiment, a cylinder is installed on one outer wall of the fixing plate, and a mounting bracket is installed on the drive end of the cylinder, with a limit wheel rotatably connected inside the mounting bracket.

[0008] In a further embodiment, two cylinders are symmetrically installed at the bottom of the liquid storage tank, and a connecting plate is installed at the drive end of the cylinder.

[0009] In a further embodiment, a rotary motor is installed on the bottom wall of the connecting plate, a drive gear is fixed to the outside of the output shaft of the rotary motor, and a driven gear that meshes with the drive gear is fixed to the outer wall of the oiling pipe.

[0010] In a further embodiment, the connecting plate has a limiting hole, and a limiting post fixedly connected to the liquid storage tank is movably connected in the limiting hole of the connecting plate. The connecting plate also has a rotating hole for the oiling pipe to rotate.

[0011] In a further embodiment, a storage battery is installed inside the base, and two handles are fixed to one outer wall of the liquid storage tank.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This railway sleeper bolt oiling device uses a self-priming pump to stably deliver lubricating oil from the storage tank to the guide pipe. The lubricating oil is initially and evenly sprayed through multiple guide holes in the guide plate. Then, a rotary motor drives the active and driven gears to rotate the oiling pipe. The wear-resistant oiling cloth on its inner wall can coat the bolts 360°, covering dead corners that are difficult for manual access, such as thread grooves and the connection between the nut and the bolt. This achieves no dead corners on the bolt surface, forming a uniform and dense anti-rust oil film, which greatly improves the actual effect of oiling and maintenance, increases work efficiency, and reduces the labor intensity of workers.

[0014] Through the linkage design of the drive motor and drive roller, it can roll forward autonomously along the rail. Compared with the traditional manual handling equipment, it greatly reduces the physical effort required to move the device. With the limit wheel driven by the cylinder, it can quickly lock and fix the device to the rail, effectively avoiding slippage and deviation during movement. At the same time, the rotating structure of the connecting seat can be adapted to track turning scenarios, ensuring that the device moves stably along the rail throughout the entire process, improving its applicability under different line conditions.

[0015] The second cylinder can precisely drive the lifting and lowering of the connecting plate and the oiling pipe. With the guide structure of the limiting hole of the connecting plate and the limiting post of the liquid storage tank, it can ensure that the oiling pipe is vertically aligned and fitted into the bolt, avoiding oil waste or uneven coating caused by device tilting. At the same time, the self-priming pump can realize the quantitative delivery of lubricating oil, effectively controlling the amount of oil applied to a single bolt. This not only eliminates the problem of missed coating, but also avoids track bed contamination caused by excessive coating, achieving efficient utilization of oil. This railway sleeper bolt oiling device is not only easier to move, but also can perform comprehensive oiling operations on the bolts, improving the oiling effect. Attached Figure Description
