Description

Technical Field

[0001] The present application relates to the technical field of sleeper maintenance, and in particular to a maintenance device and a maintenance method for concrete sleepers. Background Art

[0002] At present, railway is an important means of transportation for people to travel, so railway safety is very important. In order to ensure the safe operation of railway, it is necessary to maintain the railway, so railway maintenance is a very important matter for the railway department. Since the sleeper bolts are key parts connected and fixed to the rails, they play an important role in ensuring the safe operation of railways. However, due to the influence of the external environment, the bolts are prone to corrosion and rust, which may lead to bolt breakage, thus causing safety hazards in railway operation. Therefore, the bolts need to be oiled and maintained to prevent the bolts and nuts from decaying and rusting, thereby extending the service life of the bolts.

[0003] Bolt oiling maintenance is a routine maintenance task, which is very labor-intensive and important. The commonly used oiling maintenance method is to use a nozzle to spray anti-rust oil on the fastener connection on each sleeper, thereby extending the service life of the fastener. The spraying oiling method can generally apply anti-rust oil to part of the surface of the bolts and spring bars, but the effect of oiling the hidden gaps on the bolts and spring bars is poor. Summary of the invention

[0004] In order to facilitate the maintenance of bolts on sleepers, the present application provides a maintenance device and a maintenance method for concrete sleepers.

[0005] In the first aspect, the present application provides a maintenance device for concrete sleepers, which adopts the following technical solution: A maintenance device for concrete sleepers comprises a vehicle body and an oil barrel mounted on the vehicle body, the vehicle body being provided with an oiling barrel, the oiling barrel being connected to the oiling barrel by an oil delivery pipe, the bottom of the oiling barrel being provided with an oiling port which matches with a bolt, a baffle being provided in the oiling barrel on the side close to the oiling port, a plurality of annular oil outlets being provided on the baffle plate, the oiling barrel being provided with a piston plate located on the side close to the oiling port of the baffle plate, a first oil outlet channel being provided in the middle position of the piston plate, a second oil outlet channel being left between the outer wall of the piston plate and the inner wall of the oiling barrel, a piston rod being provided on the piston plate and passing through the oil outlet, and a sealing plate capable of sealing the oil outlet being provided on the end of the piston rod away from the piston plate.

[0006] By adopting the above technical scheme, the oiling cylinder is placed above the bolt, the end of the bolt is placed in the oiling port of the oiling cylinder, the oiling cylinder is moved downward, the bolt pushes the piston plate upward, the piston plate moves the sealing plate upward through the piston rod, and the anti-rust oil in the oil barrel enters the oiling cylinder through the oil pipe, the anti-rust oil in the oiling cylinder flows downward through the space between the sealing plate and the blocking plate, the anti-rust oil meets the piston plate after passing through the oil outlet, and flows out from the first oil outlet channel in the middle of the piston plate and the second oil outlet channel on the outside, so that the anti-rust oil can better enter the hidden gaps on the bolts and spring bars, so as to facilitate the maintenance of the bolts on the sleepers.

[0007] Optionally, a reset plate located above the blocking plate is provided in the oil cylinder, and a passage for oil to pass through is opened on the reset plate. A reset spring is provided between the reset plate and the sealing plate, and both ends of the reset spring are fixedly connected to the reset plate and the blocking plate. When the reset spring is in a natural state, the sealing plate abuts against the blocking plate.

[0008] By adopting the above technical solution, when the sealing plate moves upward, the return spring is compressed. During the oiling process, the return spring always applies a downward thrust to the sealing plate. After the oiling is moved upward and the piston plate is separated from the bolt, the compressed return spring is reset to push the sealing plate downward until the sealing plate blocks the oil outlet of the blocking plate, thereby preventing the anti-rust oil in the oiling cylinder from dripping.

[0009] Optionally, a limiting rod is provided below the reset plate, a limiting tube is provided above the blocking plate, the limiting rod is inserted into the limiting tube, and the reset spring is sleeved outside the limiting rod and the limiting tube.

[0010] By adopting the above technical solution, when the blocking plate moves up and down in the oiling cylinder, the limit rod moves inside the limit rod, ensuring the stability of the blocking plate moving straight up and down in the oiling cylinder, and at the same time protecting the return spring to prevent the return spring from bending.

[0011] Optionally, when the blocking plate abuts against the blocking plate, the distance between the end of the limiting rod and the bottom of the limiting tube is smaller than the distance between the piston plate and the blocking plate.

[0012] By adopting the above technical solution, when the oiling cylinder is moved downward and the piston plate abuts against the end of the bolt, the position of the limiting rod in the limiting tube limits the movement of the piston plate, preventing the piston plate from moving upward and abutting against the blocking plate, thereby ensuring that the anti-rust oil can flow downward from the space between the piston plate and the blocking plate.

[0013] Optionally, a connecting plate is provided on the vehicle body, a thrust cylinder is provided on the connecting plate, and the end of the thrust cylinder piston rod is fixedly connected to the top of the oiling cylinder.

[0014] By adopting the above technical solution, the oiling cylinder is moved downward by the thrust cylinder.

[0015] Optionally, a bidirectional lead screw is rotatably connected to the vehicle body, two groups of oil cylinders are provided, a connecting rod is provided on one side of the connecting plate, a connecting block is provided at the end of the connecting rod away from the connecting plate, and two connecting blocks are located on both sides of the bidirectional lead screw and are threadedly connected to the bidirectional lead screw.

[0016] By adopting the above technical solution, the bolts on the rails are generally arranged symmetrically, and then the car body is moved along the rails, and the bidirectional screw is rotated to make the connecting blocks on the bidirectional screw approach or move away from each other. The position of the connecting block is adjusted according to the position of the bolts, which facilitates the adjustment of the position of the oiling cylinder.

[0017] Optionally, a clamp is provided on the connecting rod, and the oil pipeline is connected to the clamp.

[0018] By adopting the above technical solution, the position of the oil pipeline is limited by the clamp, so as to avoid wear and tear caused by the oil pipeline contacting with the rail ground, thereby protecting the oil pipeline.

[0019] On the second aspect, the present application provides a method for maintaining concrete sleepers, which is applied to the above-mentioned equipment for maintaining concrete sleepers, and includes the following steps: placing an oiling cylinder above the bolt, placing the end of the bolt into the oiling port of the oiling cylinder, moving the oiling cylinder downward, the bolt pushes the piston plate upward, the piston plate moves the sealing plate upward through the piston rod, and the anti-rust oil in the oil barrel enters the oiling cylinder through the oil pipe. The anti-rust oil in the oiling cylinder flows downward through the space between the sealing plate and the blocking plate. After passing through the oil outlet, the anti-rust oil encounters the piston plate, and flows out from the first oil outlet channel in the middle of the piston plate and the second oil outlet channel on the outside, and the anti-rust oil enters the hidden gaps on the bolts and the spring bars.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: Place the oiling cylinder above the bolt, put the end of the bolt into the oiling port of the oiling cylinder, move the oiling cylinder downward, the bolt pushes the piston plate upward, the piston plate moves the blocking plate upward through the piston rod, and the anti-rust oil in the oil barrel enters the oiling cylinder through the oil pipe. The anti-rust oil in the oiling cylinder flows downward through the space between the blocking plate and the blocking plate. After passing through the oil outlet, the anti-rust oil meets the piston plate and flows out from the first oil outlet channel in the middle of the piston plate and the second oil outlet channel on the outside, so that the anti-rust oil can better enter the hidden gaps on the bolts and spring bars, which is convenient for the maintenance of the bolts on the sleepers; When the blocking plate moves upward, the return spring is compressed. During the oiling process, the return spring always applies a downward thrust to the blocking plate. After the oiling is moved upward and the piston plate is separated from the bolt, the compressed return spring is reset to push the blocking plate downward until the blocking plate blocks the oil outlet of the blocking plate, thereby preventing the anti-rust oil in the oiling cylinder from dripping.
