Technical Field
[0001] The utility model relates to the technical field of subway maintenance, and particularly relates to a lifting tool for the maintenance of subway platform doors. Background Technique
[0002] With the acceleration of the urbanization process, the subway, as an important part of urban public transportation, has been widely used in modern big cities due to its advantages of rapidity, convenience, environmental protection, etc. The subway platform door, as a key facility to ensure the safety of passengers and improve the operation efficiency, its normal operation is crucial for the safety of the entire subway system. However, due to long-term operation and use, various faults will inevitably occur in the platform door, and it needs to be repaired regularly or emergently. For example, when overhauling the guide rail of the platform door, it is necessary to disassemble the platform door and replace the new guide rail, and then reinstall the platform door after the guide rail replacement is completed. In the prior art, when disassembling the platform door for maintenance, multiple maintenance personnel cooperate manually to carry the platform door, which is not only laborious, but also time-consuming for carrying, and it is also necessary to fix the unloaded platform door separately, there are safety risks. For example, if the carrying operation is incorrect or careless, it may cause injury to the maintenance personnel. Manual carrying is also difficult to ensure the smoothness of the carrying process of the platform door, which may cause secondary damage to the door body and affect the maintenance quality.

[0003] The purpose of the utility model is to provide a lifting tool for the maintenance of subway platform doors aiming at the deficiencies in the above-mentioned prior art, so as to improve the convenience and safety of subway platform door maintenance.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A lifting tool for the maintenance of subway platform doors includes a claw jack, a suction cup mounting frame and a glass suction cup. The suction cup mounting frame is arranged on the lifting part of the claw jack, and a glass suction cup facing forward is arranged on the upper part of the suction cup mounting frame.
[0006] Preferably, the lifting part includes a top support and a bottom support. The suction cup mounting frame is arranged at the rear of the bottom support and is fixedly attached to the front of the vertical plate connecting the top support and the bottom support.
[0007] Preferably, a rubber pad is arranged on the upper surface of the bottom support, which can play a role in shock absorption and anti-slip.
[0008] Preferably, the glass suction cup is a single-claw glass suction cup.
[0009] Preferably, the glass suction cup is a three-claw glass suction cup, which further enhances the stability of adsorption. A suction cup release wrench is provided at the rear of the glass suction cup. When an object needs to be adsorbed, the wrench will be pressed to activate the adsorption mechanism of the glass suction cup; while when the object needs to be released, the wrench will be used to disconnect the adsorption force of the glass suction cup, so that the object can be safely removed from the glass suction cup.
[0010] Preferably, the glass suction cup is an electric suction cup, and the electric suction cup is electrically controlled, making the adsorption and release processes simpler and faster.
[0011] Preferably, a pulley is provided below the base of the claw jack.
[0012] Preferably, the pulley is provided with a locking mechanism. The design of the pulley and the locking mechanism facilitates the movement and fixation during the handling of the platform door.
[0013] Compared with the prior art, the present utility model has the following beneficial effects:
[0014] By setting the claw jack, the suction cup mounting bracket and the glass suction cup, the present utility model realizes the fixation and lifting of the platform door. While the bottom support of the claw jack holds the bottom of the platform door, the glass suction cup sucks the platform door, enabling the stable fixation of the platform door. Then, by using the lifting function of the claw jack, maintenance personnel can easily control the lifting height of the platform door, improving the convenience and safety of the maintenance of the subway platform door, reducing the possibility of door body damage, and lowering the maintenance cost.

[0019] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will describe the present utility model in detail with reference to the drawings and specific embodiments.
[0020] As Figure 1 shown, a lifting tool for the maintenance of subway platform doors includes a claw jack 1, a suction cup mounting bracket 2, and a glass suction cup 3. The suction cup mounting bracket 2 is arranged on the lifting part of the claw jack 1, and the upper part of the suction cup mounting bracket 2 is provided with a glass suction cup 3 facing forward. The lifting part includes a top support 1-5 and a bottom support 1-6. The suction cup mounting bracket 2 is arranged at the rear of the bottom support 1-6 and is fixedly attached to the front of the vertical plate connecting the top support 1-5 and the bottom support 1-6.
[0021] The upper surface of the bottom support 1-6 is provided with a rubber pad, which can play a role in shock absorption and anti-slip.
[0022] The glass suction cup 3 is a single-claw glass suction cup.
[0023] The glass suction cup 3 can also be a three-claw glass suction cup to further enhance the adsorption stability. A suction cup release wrench is provided at the rear of the glass suction cup 3. When an object needs to be adsorbed, the wrench will be pressed to activate the adsorption mechanism of the glass suction cup 3; while when the object needs to be released, the wrench will be used to disconnect the adsorption force of the glass suction cup 3 so that the object can be safely removed from the glass suction cup 3.
[0024] The glass suction cup 3 can also be an electric suction cup. The electric suction cup is controlled electrically, making the adsorption and release processes simpler and faster.
[0025] A pulley is provided below the base 1-1 of the claw jack 1. The pulley is provided with a locking mechanism. The design of the pulley and the locking mechanism facilitates the movement and fixation during the handling of the platform door.
[0026] The working principle of the present utility model:
[0027] When performing the maintenance of the subway platform door, first open the hydraulic valve of the oil cylinder 1-4 of the claw jack 1. The lifting part of the claw jack 1 falls back to the lowest position under the elastic force of the spring 1-2, and the bottom support 1-6 drops to the lowest point. Insert the bottom support 1-6 into the gap under the bottom of the platform door and make the glass suction cup 3 contact the outer surface of the platform door. Then operate the lever 1-3 to raise the oil cylinder 1-4 and drive the bottom support 1-6 to rise until the bottom support 1-6 contacts the bottom of the platform door. At this time, use the glass suction cup 3 to suck the platform door, and then disassemble other components. If the platform door needs to be moved away, the platform door and this device can be moved away together. After the repair is completed, move it back and complete the installation of the platform door.
