Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation, in particular to an anti-fall elevator installation construction platform. Background Art

[0002] When installing an elevator, it is usually necessary to set up a construction platform inside the elevator shaft to provide support for the workers. During the construction process, the motor for winding the suspension wire is often damaged, causing the entire construction platform to fall. In order to avoid this situation, it is usually necessary to use an anti-fall structure to prevent the construction platform from falling.

[0003] Chinese Patent Publication No.: CN220395146U discloses a "Lock Rail Trigger Mechanism for Preventing an Elevator Installation Construction Platform from Falling", which includes a main body and a resistance mechanism. A mounting plate is clamped on the top of the main body, support rods are welded on both sides of the main body, and a U-shaped groove is welded on the bottom end of the support rod. A resistance mechanism is provided inside the main body, and an inertial sensor is clamped inside the main body. The inertial sensor will transmit the sudden inertial information to the processor, and the processor will transmit the start instruction to the hydraulic controller via the instruction transmitter. The hydraulic controller starts the hydraulic press, and the oil in the oil tank passes through the oil outlet pipe to the hydraulic cylinder to push the hydraulic rod out, so that the prevention plate contacts the surface of the slide rail, increases friction and reduces the falling speed until it stops. The device prevents the construction platform from falling by increasing resistance, effectively preventing the construction platform from falling and ensuring the safety of construction workers.

[0004] In the prior art, when in use, the anti-fall device installed on the existing elevator installation construction platform needs to use sensing to determine whether the elevator has fallen. When the sensing fails, it is difficult to directly perform anti-fall processing, which poses certain hidden dangers. Utility Model Content

[0005] The purpose of the present utility model is to provide an anti-fall elevator installation and construction platform to solve the problem that the anti-fall device installed on the existing elevator installation and construction platform in the above-mentioned background technology needs to judge whether the elevator has fallen by sensing. When the sensing fails, it is difficult to directly perform anti-fall treatment, which poses certain hidden dangers.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an anti-fall elevator installation construction platform, comprising two sets of mounting plates, two sets of anti-fall components movably provided on the inner sides of the mounting plates, and the anti-fall components are used to prevent the platform from falling, and pull-out storage components are installed on the inner sides of both ends of the anti-fall components, and the pull-out storage components are used to store items to avoid affecting construction;

The grip will be adjusted by pulling the movable block at the end through the wire rope. The movable block will drive the pushing block and the wire rope at the end to retract through the connecting column. Only after retraction can it be adjusted downward.

The simple anti-fall structure can effectively avoid the problem of falling due to loss of tension caused by the top motor.

[0028] Through the above technical solution, a limiting frame 201 is set to provide an installation position for the inner structure, and the height can be adjusted by using the pull-out tool box 5. After adjustment, the flip plate 506 can be lifted and opened, and the internal tools can be taken out after flipping and unfolding.

[0029] Specifically, four groups of limit plates 101 are installed on the inner side of the mounting plate 1, and the limit plates 101 are located on the outside of the limit frame 201. Two rows of several groups of positioning grooves 102 are opened on one side of the mounting plate 1, and the positioning grooves 102 are located on the inner sides of the two groups of limit plates 101.

[0038] Through the above technical solution, the mounting bracket 501 cooperates with the fixing bolts 502 to connect the fixing frame 503 to the mounting platform 2.

[0039] Specifically, a limiting sliding groove 504 is provided on the inner side of the fixed frame 503 , and the limiting sliding groove 504 is located on the outer side of the sliding block.

[0040] Through the above technical solution, the limiting sliding groove 504 can limit the inner sliding block and increase the stability of the sliding adjustment.

[0041] When in use, the device is first installed. When performing lifting and adjustment, it is necessary to use the external suspension motor to pull the suspension wire 402 to drive the installation platform 2 to lift slightly. After lifting, the staff drives the internal wire rope 402 to move by grasping the auxiliary handle 401. During the movement, the internal movable block 404 and the pushing block 406 are controlled to move and retract. After retraction, the positioning block 4 is separated from the positioning groove 102. After separation, the height can be adjusted, and then the strong spring 407 will squeeze the pushing block 406 and the positioning block 4 outward and insert it into the inner side of the positioning groove 102 to achieve a limiting effect. When installing, you can grasp the groove on the top of the tool box 5 and pull it out. After pulling it out, control the flip plate 506 to flip along the limit sleeve 505 to open and take out the internal tools.
