Description

Technical Field

[0001] This application relates to the field of elevator inspection technology, specifically a protective device for elevator inspection. Background Technology

[0002] Elevator inspection is a process of systematically checking, testing, and evaluating elevator equipment and its operating environment, aiming to ensure the safe operation of elevators, prevent accidents, and protect the safety of passengers and maintenance personnel.

[0003] Maintenance personnel need to stop the elevator for each inspection, meaning the car must be out of service. They must stand on top of the car, which needs to be stopped in the shaft to be inspected, or it can be hoisted directly into the shaft from the elevator entrance. However, whether standing on top of the car or suspended in the shaft, there are dangers. First, there is no protection against falling objects from above, and second, there is no protection against the car falling uncontrollably, especially during elevator malfunction repairs. Personnel protection relies solely on safety clothing and helmets; other measures must ensure the slings are secure and the car is stable.

[0004] Therefore, this application provides a protective device for elevator inspection to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a protective device for elevator inspection, which aims to solve the problem that existing elevator inspection and protection devices have safety hazards as mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a protective device for elevator inspection, comprising a car track, on which a working platform detachable from the top of the car is provided. Each of the four corners of the working platform has an electric suction cup for attaching to the top of the car. Track drive components for driving the working platform to move on the car track are fixedly installed on the sides of the working platform. The working platform has a guardrail along its edge, and a hanging net is fixedly installed on the guardrail. In this way, the combination of the electric suction cups and the track drive components allows the platform to operate independently of the car. Even if the car becomes uncontrollable, the platform can still remain stable via the track, preventing personnel from falling with the car. Simultaneously, the hanging net covers the work area, effectively intercepting falling objects such as tools and screws, reducing the risk of head injuries.

[0007] Preferably, the track drive assembly includes a pair of friction wheels rotatably mounted on the side of the work platform and respectively in contact with both sides of the car track, a motor fixedly mounted on the work platform and whose output shaft is connected to one of the friction wheels, a pair of brake arms hinged on the work platform at positions corresponding to both sides of the car track and moving closer or further away from each other, and a double-headed push rod disposed between the brake arms and with its two ends respectively hinged to the two brake arms. The movable ends of the brake arms each have rubber pads for contacting the car track to brake.

[0008] Preferably, auxiliary stabilizing wheels are rotatably installed on the working platform at positions corresponding to both sides of the car track.

[0009] Preferably, the guardrail includes fixed posts fixedly connected to the four corners of the top of the work platform, guardrail crossbars fixedly connected between two adjacent fixed posts, and uprights fixedly connected to the top of the fixed posts, the top of the uprights having hooks for attaching the hanging net.

[0010] Preferably, each of the fixing columns has a plug bar on its side.

[0011] Preferably, a cluster light is fixedly installed at the top of each of the fixed columns via a flexible metal tube.

[0012] Preferably, a rubber buffer pad is fixedly installed at the center of the bottom of the work platform.

[0013] The elevator inspection safety device combines an electric suction cup with a track drive assembly, allowing the platform to operate independently of the car. Even if the car goes out of control, the platform can still remain stable via the track, preventing personnel from falling with the car. At the same time, the hanging net covers the work area above, effectively intercepting falling objects such as tools and screws, reducing the risk of head injuries.

[0014] The elevator inspection safety device allows the platform to move quickly along the track to different inspection points, reducing the number of repeated climbing or hoisting operations and shortening the inspection time. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment provides a protective device for elevator inspection, such as... Figures 1-5 As shown, the elevator inspection protective device includes a car track 1, a working platform 2 that can be detached from the top of the car is provided on the car track 1, the four corners of the bottom of the working platform 2 are provided with electric suction cups 23 for adhering to the top of the car, the sides of the working platform 2 are fixedly installed with track drive components 3 for driving the working platform 2 to move on the car track 1, the edge of the working platform 2 is provided with a guardrail 21, and a hanging net 22 is fixedly installed on the guardrail 21.

[0027] In use, the electric suction cups 23 at the four corners of the bottom of the work platform 2 adhere tightly to the top surface of the car using vacuum adsorption technology. When the inspection personnel activate the adsorption function, the vacuum pump inside the electric suction cup 23 works to expel the air between the suction cup and the top of the car, creating a negative pressure environment that firmly connects the work platform 2 to the top of the car, preventing the platform from falling off due to accidental movement or fall of the car. The track drive assembly 3 works in conjunction with the car track 1, driving the work platform 2 to move laterally or longitudinally along the track via electricity. The inspection personnel can adjust the movement speed and direction via remote control or control panel to achieve precise positioning to different inspection areas within the shaft. The guardrail 21 is set around the edge of the work platform 2 to prevent personnel from falling. The hanging net 22 is fixed to the top of the guardrail 21 to form a flexible safety net that can catch tools or debris falling from above, preventing injury to personnel below.

[0028] Specifically, the track drive assembly 3 includes a pair of friction wheels 31 rotatably mounted on the side of the work platform 2 and respectively in contact with both sides of the car track 1; a motor 32 fixedly mounted on the work platform 2 with its output shaft connected to one of the friction wheels 31; a pair of brake arms 34 hinged on the work platform 2 at positions corresponding to both sides of the car track 1 and moving closer or further away from each other; and a double-headed push rod 35 disposed between the brake arms 34 and hinged at both ends to the two brake arms 34 respectively. The movable ends of the brake arms 34 each have rubber pads 341 for contacting the car track 1 to brake. The work platform 2 at positions corresponding to both sides of the car track 1 rotates... An auxiliary stabilizing wheel 33 is installed; a motor 32 drives one of the friction wheels 31 to rotate via gear or belt transmission. The surface of the friction wheel is made of high-friction coefficient rubber, which generates static friction when it contacts both sides of the car track 1, pushing the working platform 2 to move laterally or longitudinally along the track; a double-headed push rod 35 pushes the brake arms 34 on both sides through a hinge structure, so that the rubber pad 341 clamps the car track 1. The elastic deformation of the rubber pad can increase the contact area and improve the braking force; the auxiliary stabilizing wheel 33 and the friction wheel 31 form a double-point positioning to prevent the platform from shifting due to uneven track during movement, distribute the pressure of the platform weight on the friction wheel, and extend the life of the drive components.

[0029] Specifically, the guardrail 21 includes fixed posts 211 fixedly connected to the four corners of the top of the work platform 2, guardrail crossbars 212 fixedly connected between two adjacent fixed posts 211, and uprights 221 fixedly connected to the top of the fixed posts 211. The top of the uprights 221 has hooks 2211 for hanging the hanging net 22. The four fixed posts 211 are fixed to the four corners of the work platform 2 with bolts, and the guardrail crossbars 212 are welded between adjacent fixed posts to form a rigid frame. The hooks 2211 at the top of the uprights 221 are used to hang the hanging net 22.

[0030] Furthermore, each side of the fixing post 211 has a power strip 214; inspectors can directly connect power tools, avoiding the risk of dragging external cables.

[0031] Furthermore, each of the fixed columns 211 has a cluster light 2131 fixedly installed at its top via a metal flexible tube 213; the metal flexible tube can adjust the direction of the light to cover dark areas such as the top of the shaft and gaps in the car.

[0032] Furthermore, a rubber buffer pad 24 is fixedly installed at the center of the bottom of the work platform 2; when the platform falls accidentally, the buffer pad absorbs the impact energy through compression and deformation.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
