Description

Technical Field

[0001] This utility model relates to the field of bridge bearing replacement technology, and in particular to an auxiliary device for bridge bearing replacement. Background Technology

[0002] Bridge bearing replacement is a complex project requiring precision and safety. To ensure a smooth replacement process, various auxiliary equipment is needed, with jacks being a common choice. Jacks are used to temporarily lift the bridge, unload the load from the existing bearings, and maintain the bridge's stability for bearing replacement. Common hydraulic jacks have high load capacities.

[0003] Most traditional hydraulic jacks lack an automatic lubrication system. Therefore, when a hydraulic jack needs lubrication to ensure proper operation, operators typically need to manually inject lubricant using external equipment. This not only increases operational complexity but can also lead to delays and human error. Furthermore, the lubrication process for traditional hydraulic jacks usually requires regular checks and manual maintenance to ensure long-term stability and efficiency. This manual intervention in lubrication can easily result in uneven lubrication, insufficient quantity, or improper use, affecting the jack's performance and potentially causing damage or shortening its lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary device for replacing bridge bearings, which aims to improve the problem that most hydraulic jacks in traditional technology are not equipped with an automatic lubrication mechanism, resulting in reduced stability and reduced service life of the jacks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bridge bearing replacement auxiliary device, comprising a base, a hydraulic cylinder fixedly connected to the top of the base, a hydraulic rod fixedly connected to the output end of the hydraulic cylinder, an oil suction device fixedly connected to the outside of the hydraulic cylinder, an oil injection mechanism provided outside the hydraulic cylinder for injecting lubricating oil into the oil suction device, an installer fixedly connected to the bottom of the hydraulic cylinder, a connector slidably connected inside the installer, a connecting wire fixedly connected to the side of the connector away from the installer, a slot provided outside the connector, and a locking mechanism provided inside the installer for more stable installation of the connecting wire;

[0006] The oil injection mechanism includes a mounting plate, which is fixedly connected to the outside of the hydraulic cylinder. A mounting shell is fixedly connected to the side of the mounting plate away from the hydraulic cylinder. A compression spring is fixedly connected inside the mounting shell. A piston is fixedly connected to the bottom of the compression spring. A push rod is fixedly connected inside the piston.

[0007] As a further description of the above technical solution:

[0008] A push handle is fixedly connected to the top of the push rod, the push rod is slidably connected inside the mounting housing, and the piston is slidably connected inside the mounting housing.

[0009] As a further description of the above technical solution:

[0010] An oil delivery pipe is fixedly connected to the outside of the mounting housing, and one end of the oil delivery pipe away from the mounting housing is fixedly connected to the top of the oil suction device.

[0011] As a further description of the above technical solution:

[0012] A one-way valve is installed at the top of the oil pipeline, and a two-way valve is installed at the bottom of the oil pipeline.

[0013] As a further description of the above technical solution:

[0014] The engaging mechanism includes a slide rod slidably connected inside the installer. A slider is fixedly connected to the bottom of the slide rod, and a return spring is fixedly connected to the bottom of the slider. Connecting rods are slidably connected to both sides of the slider. U-shaped brackets are fixedly connected to the bottom of both connecting rods. Locking rods are fixedly connected to the bottom of both U-shaped brackets. Clamps are fixedly connected to the opposite sides of both locking rods, and both clamps engage with the locking groove.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] The bottom of the return spring is fixedly connected inside the mounter.

[0019] As a further description of the above technical solution:

[0020] A handle is fixedly connected to the top of the slide bar.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when lubricating oil needs to be injected into the hydraulic cylinder, the push handle pulls up the push rod, causing the piston to move upward and compress the compression spring. The compression spring rebounds under force and pushes the piston downward. This process is repeated to force the lubricating oil inside the mounting housing into the oil suction device through the oil delivery pipe. One-way valve one and one-way valve two simultaneously prevent the lubricating oil from flowing back, thus achieving the effect of injecting lubricating oil into the hydraulic cylinder through the oil injection mechanism, improving the stability of the device operation and extending the service life of the device.

[0023] 2. In this utility model, when installing the connecting wire, pushing the slider downwards with the handle causes the slider to move downwards and compress the return spring. When the slider moves downwards, the connecting rods on both sides cause the two U-shaped brackets to drive the two clamping rods, causing the two clamps to separate relative to each other. At this time, the connecting wire and connector can be slid into the interior of the installer. Releasing the handle causes the return spring to push the slider upwards, causing the two clamps to come together and engage with the slot for fixation. This achieves the effect of enhancing the stability of the connecting wire installation through the engaging mechanism, improving the stability of the device in complex environments, and enhancing the practicality of the device.

A locking mechanism is provided inside the installer 14 to more stably install the connecting wire 16.

[0032] The oil injection mechanism includes a mounting plate 5, which connects to the mounting shell 6. The mounting plate 5 is fixedly connected to the outside of the hydraulic cylinder 2. The mounting shell 6 is fixedly connected to the side of the mounting plate 5 away from the hydraulic cylinder 2. The mounting shell 6 fixes the internal structure. A compression spring 7 is fixedly connected inside the mounting shell 6. The compression spring 7 provides elastic force to push the piston 8. The piston 8 is fixedly connected to the bottom of the compression spring 7. A push rod 9 is fixedly connected inside the piston 8. The push rod 9 connects to the piston 8. A push handle 10 is fixedly connected to the top of the push rod 9. The push rod 9 is slidably connected inside the mounting shell 6. The piston 8 is slidably connected inside the mounting shell 6. An oil supply pipe 11 is fixedly connected to the outside of the mounting shell 6. The end of the oil supply pipe 11 away from the mounting shell 6 is fixedly connected to the top of the oil suction device 4. A one-way valve 12 is provided at the top of the oil supply pipe 11, and a two-way valve 13 is provided at the bottom of the oil supply pipe 11.

[0033] Specifically, when injecting lubricating oil, the piston 8 is driven to reciprocate by the push rod 9 to inject the lubricating oil in the mounting shell 6 into the oil suction device 4.

[0034] Reference Figure 1 and Figures 3-4The engaging mechanism includes a slide rod 18, which connects to a slider 19. The slide rod 18 is slidably connected inside the installer 14. The bottom of the slide rod 18 is fixedly connected to the slider 19, which connects to a return spring 20. The bottom of the slider 19 is fixedly connected to the return spring 20, which provides elastic force to push the slider 19. Both sides of the slider 19 are slidably connected to connecting rods 21, which connect to U-shaped frames 22. The bottom of both connecting rods 21 is fixedly connected to U-shaped frames 22, which connect to locking rods 23. The bottom of both U-shaped frames 22 is fixedly connected to locking rods 23, which connect to clamps 24. The opposite sides of both locking rods 23 are fixedly connected to clamps 24, which engage with the slots 17.

[0035] Specifically, the reset spring 20 pushes the slider 19, causing the lever 23 to drive the two clamps 24 to clamp the connector 15 and prevent it from falling off.

[0036] Working principle: When performing the operation, multiple of these devices are set up next to the bridge supports. The hydraulic cylinder 2 is activated at the same time to lift the bridge deck through the hydraulic rod 3 until the support can be removed. After replacing the support with a new one, the hydraulic rod 3 is lowered until the bridge deck is completely supported on the support, and then the device can be removed.

[0037] When lubricating oil needs to be injected into the hydraulic cylinder 2, the push rod 9 is pulled up by the push handle 10, causing the piston 8 to move upward and compress the compression spring 7. The compression spring 7 rebounds under force and pushes the piston 8 downward. This process is repeated to force the lubricating oil inside the mounting shell 6 into the oil suction device 4 through the oil supply pipe 11. The one-way valve 12 and the one-way valve 2 13 simultaneously prevent the lubricating oil from flowing back.

[0038] When installing the connecting cable 16, push the slide bar 18 downward by the handle 25 to move the slider 19 downward and compress the return spring 20. When the slider 19 moves downward, the connecting rods 21 on both sides cause the two U-shaped brackets 22 to drive the two clamps 23 to separate the two clamps 24. At this time, the connecting cable 16 and the connector 15 can be slid into the interior of the installer 14. Release the handle 25 and the return force of the return spring 20 pushes the slider 19 upward, so that the two clamps 24 come together and engage with the slot 17 to fix them.
