Description

Technical Field

[0001] The utility model relates to the technical field of elevator inspection, in particular to an elevator inspection auxiliary device. Background Art

[0002] An elevator is a transportation device serving building floors. With the continuous construction of high-rise buildings in cities, elevators have gradually become necessities of life. After an elevator has been used for a period of time, it is necessary for staff to conduct regular inspections on the elevator to ensure its normal use. In the prior art, when inspecting an elevator, staff need to climb onto the top of the elevator box using a ladder for inspection.

[0003] For example, the authorized announcement number "CN221318813U" is an elevator inspection auxiliary device. By adjusting the baffle provided by the device to abut against the inner wall of the elevator body, the effect of limiting the moving direction of the ladder is achieved, avoiding the situation where the ladder slides to one side when the staff climbs the ladder, thus preventing the staff from falling. However, for the existing elevator inspection auxiliary device, since a relatively large base is used to obliquely support the ladder inside the elevator car to be inspected, due to the narrow space in the elevator car, after the relatively large base is fixed on one side of the bottom end of the elevator car, the space inside the elevator for people to stand and move becomes even smaller. At the same time, the operator must pass above the baffle controlled by the screw before climbing onto the ladder, and it is easy to trip when moving up and down, affecting the use effect of the elevator inspection auxiliary device.

[0004] At the same time, for the existing elevator inspection auxiliary device, since the elevator inspection auxiliary device needs to be carried by the operator into the built elevator and assembled temporarily after opening the elevator top plate, but the volume of the elevator inspection auxiliary device itself is relatively large, and the space of the left and right sliding doors of the elevator is limited, so it is difficult for an operator to complete the process of carrying, placing into the car and assembling it alone, and multiple staff members are needed to assist to achieve quick use, resulting in a relatively high use cost of the elevator inspection auxiliary device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of poor use effect and too high use cost of the existing elevator inspection auxiliary device, and to propose an elevator inspection auxiliary device.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Design an elevator inspection auxiliary device, including an elevator main body, an elevator inspection hole and a ladder. The elevator inspection hole is fixedly opened at the top of the elevator main body. The ladder is movably placed inside the elevator main body. A plurality of cross beams are fixedly installed inside the ladder. The bottom end of the ladder is provided with a support structure with reserved upper and lower spaces on both sides. The two sides of the ladder are provided with a ladder folding structure to reduce the occupied space.

[0008] Preferably, the support structure with reserved upper and lower spaces includes a support seat and a fixed sleeve. The support seat is fixedly installed at the bottom end of the ladder. Two rotating shafts are rotatably connected to both sides of the outer wall of the support seat. Two fixed sleeves are fixedly sleeved on the outer sides of the two rotating shafts. Two movable rods are slidably connected to the inner sides of the two fixed sleeves. A plurality of through holes are fixedly opened on the outer sides of the two movable rods. Two bolts are movably connected to the outer sides of the two fixed sleeves. The inner sides of the two bolts are movably connected to the inner sides of the through holes. The other ends of the two movable rods are fixedly installed with two gaskets.

[0009] Preferably, the bottom end of the support seat is movably connected to the inner wall bottom end of the elevator main body. The outer walls of the two gaskets are movably connected to the inner wall of the elevator main body. The two fixed sleeves are arranged parallel to each other relatively.

[0010] Preferably, the ladder folding structure to reduce the occupied space includes a storage groove and a connecting block. The two storage grooves are fixedly connected to both sides of the outer wall of the ladder. The lower ends of the two storage grooves are fixedly connected with two connecting blocks. The ends of the two connecting blocks are fixedly connected with straps. The ends of the multiple straps are fixedly connected with Velcro. The outer side of the Velcro is movably connected to the outer wall of the strap.

[0011] Preferably, the inner side of the storage groove is movably connected to the outer wall of the fixed sleeve. The inner sides of the two straps are movably connected to the outer wall of the fixed sleeve.

[0012] Preferably, an anti - detachment block is fixedly connected to the top end of the ladder. The top end of the ladder is movably connected to the inside of the elevator inspection hole. The end of the anti - detachment block is movably connected to the top end of the elevator main body.

[0013] The beneficial effect of the elevator inspection auxiliary device proposed by the present utility model is as follows: When it is necessary to fix the ladder, the operator manually flips the two fixed sleeves and rotates counterclockwise by 90 degrees along the support seat, so that the gaskets at the ends of the two movable rods are tightly attached to the inner wall of the elevator main body. The bolt fixes the movable rod inside the fixed sleeve, and one side of the support seat is tightly attached to the inside of the elevator main body to form a support. In this way, a certain space will be reserved for the staff to move up and down between the two fixed sleeves, which is not easy to trip the operator and improves the use effect of the elevator inspection auxiliary device.

[0014] The storage groove enables the fixed sleeve to be flush with both sides of the ladder, facilitating storage. The strap is made of a leather material with good toughness and is not easily broken. The strap is wound around the outside of the fixed sleeve in the storage groove, and finally the end of the tied strap is adhered to the outside of the strap itself with Velcro. In this way, the fixed sleeve and the ladder can be folded up, reducing the space for handling and making it more convenient, and reducing the use cost of the elevator inspection auxiliary device.
