Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, and in particular to a safety protection device for elevator car top maintenance. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for transporting people or goods in multi-story buildings. Modern elevators mainly consist of a traction machine (winch), guide rails, counterweight, safety devices (such as speed governors, safety brakes, and buffers), signal control system, car, and landing doors. These components are installed in the building's shaft and machine room, respectively. They typically use friction drive with steel wire ropes. The steel wire ropes pass around the traction sheave, with both ends connected to the car and the counterweight, respectively. The electric motor drives the traction sheave to raise and lower the car. During maintenance or repair, the elevator car top needs to be supported and secured to ensure the safety of maintenance personnel. Current safety devices are susceptible to severe compression during elevator swaying, leading to significant damage. Furthermore, the current integrated structure of these devices is inconvenient to move, thus requiring improvement. Utility Model Content

[0040] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an elevator car top inspection and safety protection device.

[0041] An elevator car top maintenance safety protection device includes a base 1, and further includes: a mounting column 2, which is disposed on the base 1 and fixedly connected to the base 1; a lifting cylinder 3, which is disposed inside the mounting column 2 and fixedly connected to the mounting column 2; a connector 4, which is disposed on the lifting cylinder 3 and fixedly connected to the lifting cylinder 3; a first threaded hole 5, which is disposed on the connector 4 for connecting components; and an anti-pinch mechanism, which is disposed on the connector 4 for mitigating the pinch damage caused to the device by elevator swaying.

[0042] refer to Figure 1 and Figure 2 In a preferred embodiment, the anti-pinch mechanism includes: a connecting part disposed on the connector 4 for mounting the swaying mechanism; and a rotating part disposed on the connecting part for mitigating the damage caused to the device by elevator swaying.

[0043] refer to Figure 4 and Figure 5 In a preferred embodiment, the connecting part includes: a connector 6 disposed on the connector 4 for fixing the connecting component in conjunction with the connector 4; a second threaded hole 7 disposed on the connector 6 for connecting the component; and a fixing bolt 8 disposed in the first threaded hole 5 and the second threaded hole 7, and threadedly connected to the first threaded hole 5 and the second threaded hole 7.

[0044] refer to Figure 3 and Figure 5 In a preferred embodiment, the rotating part includes: a mounting plate 9, disposed on and fixedly connected to the connector 6; two mounting members 10, disposed on and fixedly connected to the mounting plate 9; a rotating member 11, disposed on and rotatably connected to the mounting member 10; a top plate 12, disposed on and fixedly connected to the rotating member 11; and multiple buffer springs 13, disposed between the top plate 12 and the mounting members 10 and fixedly connected to the top plate 12, and the buffer springs 13 are fixedly connected to the mounting members 10.

[0045] The top plate 12 is made of steel, which has high strength. The position where the top plate 12 connects to the buffer spring 13 is set as an inclined surface, so that the inclined placement of the buffer spring 13 can better adapt to the movement trajectory of the top plate 12 when it rotates. The connector 4 and the connector 6 are both made of steel, which has high strength. The connector 4 and the connector 6 can cooperate with each other, and the connector 6 can be inserted into the connector 4. Then, the connector 4 and the connector 6 are fixed by the fixing bolt 8. The top plate 12 and the rotating part 11 can keep the top plate 12 in contact with the elevator car top when the elevator shakes during operation, preventing uneven force on the top plate 12 and causing squeezing damage, thus ensuring the safety of this device.

[0046] This device incorporates a safety protection mechanism for elevator car top maintenance. It provides support during elevator car top maintenance, ensuring the safety of maintenance personnel. Furthermore, the device is easy to disassemble, carry, and use. By incorporating an anti-pinch mechanism, the device maintains constant contact with the elevator car top during operation, preventing damage from pressure on one side of the device during elevator swaying and extending its service life.

[0047] When using this device, place the base 1 of the device in the required position, then insert the connector 6 into the connector 4, and then use the fixing bolt 8 to fix the connector 6 and the connector 4 together through the first threaded hole 5 and the second threaded hole 7. Then, start the lifting cylinder 3 to bring the top plate 12 into contact with the top of the elevator car, so that the device can play a supporting role. When facing the swaying of the elevator during operation, the top plate 12 will rotate around the mounting part 10 through the rotating part 11, so that the top plate 12 is always in contact with the top of the car to prevent uneven force on the top plate 12 and damage caused by squeezing. At the same time, the top plate 12 will squeeze the buffer spring 13 to reduce the force, thereby protecting the device and reducing the damage to the device caused by the swaying of the elevator.

[0048] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
