Description

Technical Field

[0001] The utility model belongs to the technical field of elevator inspection and testing protection, and particularly relates to a safety protection device for elevator inspection and testing. Background Art

[0002] During the installation and use of an elevator, it is necessary for workers to go above the elevator for maintenance. In order to ensure the safety of maintenance workers during maintenance, it is necessary to set up a protection device outside the elevator to block and remind external personnel, thereby protecting the workers during the maintenance process.

[0003] Most of the existing safety protection devices for elevator inspection and testing directly use simple warning signs or fences placed at the elevator entrance for protection. However, this kind of protection device is easily moved by mistake, and the blocking effect on personnel is very small. When people cannot be seen inside the elevator, it is still possible to enter the elevator for use, which will bring certain safety risks to both users and workers. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that most of the existing safety protection devices for elevator inspection and testing directly use simple warning signs or fences placed at the elevator entrance for protection. However, this kind of protection device is easily moved by mistake, and the blocking effect on personnel is very small, which will bring certain safety risks to both users and workers.

[0005] To solve the above technical problem, the technical solution provided by the utility model is a safety protection device for elevator inspection and testing, including two protection plates. The two protection plates are connected by a rotating shaft. Guide chutes are arranged at the upper and lower ends inside the protection plates. A moving rod is slidably connected inside the guide chute. One end of the moving rod close to the edge of the protection plate passes through one side of the guide chute. The upper and lower moving rods are connected by a support rod. And a fixing plate is commonly connected to the outside of the upper and lower moving rods at the end close to the edge of the protection plate. A rubber pad is arranged on the outside of the fixing plate. A positioning rod is arranged in the middle of the support rod inside the protection plate. Multiple external threads are arranged on the positioning rod, and one side of the support rod is connected with the external threads through a positioning sleeve.

[0006] Preferably, the rotating shaft is vertically arranged with one end of the protection plate. The distance between the rotating shaft and the protection plate is greater than the width of the guide chute. And a buffer pad is arranged outside the guide chute. The sum of the thicknesses of the guide chute and the buffer pad is the same as the distance between one side of the rotating shaft and the protection plate.

[0007] Through the above technical solution, during the process of moving and folding the safety protection device, the buffer pads prevent collisions between the inner structures, thereby ensuring that the inner side of the protection plate will not be damaged during moving, folding and storage.

[0008] Preferably, a prompt sign is provided on the outer side of the protection plate.

[0009] Through the above technical solution, it can effectively remind people not to use the elevator externally.

[0010] Preferably, a handle is provided at the middle position above one side of the guiding chute.

[0011] Through the above technical solution, it is convenient to move the protection device, and the fixed height can be determined through the handle.

[0012] Preferably, the shape of the moving rod matches the shape inside the guiding chute, and an "open" structure is formed among the two moving rods, the fixing plate and the supporting rod on both sides. The widths of the two moving rods, the fixing plate and the supporting rod on both sides are all smaller than the width of the guiding chute.

[0013] Through the above technical solution, there will be no contact on both sides during folding, and there is enough space to move the supporting rod.

[0014] Preferably, a plurality of anti-slip grooves are provided on the outer surface of the rubber pad, and the directions of the plurality of anti-slip grooves are perpendicular to the protection plate.

[0015] Through the above technical solution, it prevents the protection plate from sliding down during the fixing process.

[0016] Preferably, a corresponding movable opening is provided at the position of the supporting rod where the positioning rod is located, and the inner diameter of the movable opening is larger than the diameter of the external thread on the positioning rod.

[0017] Preferably, one end of the positioning sleeve is rotatably connected to the side of the supporting rod away from the fixing plate, and the inner part of the positioning sleeve is in threaded connection with the external thread on the positioning rod through internal threads.

[0018] Preferably, both ends of the positioning rod are fixedly connected to the protection plate through mounting seats, and multiple sections of the external threads are respectively located at one end of the positioning rod away from the fixing plate and at the middle part close to the fixing plate.

[0019] Through the above technical solution, the fixing of the protection plate in the storage state and the state of supporting and fixing both sides of the elevator is realized respectively.

[0020] The advantages of the present utility model compared with the prior art are as follows:

[0021] This safety protection device directly extends through the fixed plates on both sides and is fixed to both sides of the elevator door, thus blocking the passage into the elevator. Moreover, the positions of fixation and release are on the inner side of the protection plate, which is not easily adjustable from the outside. It can effectively prevent people from moving the protection plate and entering the interior of the elevator, thereby providing a strong protection effect for the interior, preventing dangers during the maintenance process of the staff, and effectively protecting the safety of the staff.

And the directions of the plurality of anti-slip grooves 14 are perpendicular to the protection plate 1.

[0033] In the present utility model, a positioning rod 8 is arranged at the middle of the protection plate 1 inside the support rod 5. Multiple sections of external threads 9 are arranged on the positioning rod 8.
