Description

Technical Field

[0001] The utility model relates to the technical field of elevator load-bearing detection, in particular to a load-bearing detection device for elevator detection. Background Art

[0002] In the ever-changing modern life, high-rise buildings are rising from the ground, and elevators are widely used. The safety of elevators is very important. In the elevator structure, the load-bearing beam and the traction machine are the two main components of the elevator, and the traction machine load-bearing beam is an important component that supports this main component. Due to the structural characteristics of the elevator, the load-bearing beam not only supports the traction machine, but also the entire elevator. Including the car, load, counterweight, cable, wire rope, etc. are all hung on the load-bearing beam through the traction machine, so the load-bearing detection of the load-bearing beam is related to people's life safety. If the load-bearing beam is not inspected and maintained for a long time, it will affect the service life of the elevator and affect the normal operation of the equipment.

[0003] In the authorization announcement number CN220362483U, an elevator load-bearing detection device is disclosed, which includes a base, a support frame fixedly connected to the top of the base, a movable plate arranged on the top of the base, two symmetrical adjustment slots arranged on the top of the movable plate, a detection block fixedly connected to the top of the movable plate, a second threaded rod rotatably connected to the inside of the movable plate, both ends of the second threaded rod rotate through the inside of the movable plate and extend to the inside of the adjustment slot, and a positioning plate is slidably connected to the inside of the two adjustment slots. The elevator load-bearing detection device reduces the occurrence of deviations in the detection of the load-bearing beam due to the displacement of the placement of the load-bearing beam during the load-bearing detection, and allows the staff to use the device more conveniently;

[0004] However, the above patent still has the following problems: when the load-bearing beam is clamped and fixed by the positioning plate, there is friction between the positioning plate and the load-bearing beam. When the load-bearing beam is pressed downward, it will be subject to the upward friction of the positioning plate, thereby affecting the detection result of the load-bearing beam and causing inaccurate detection. Moreover, since the height of the rotating shaft is lower than the height of the detection block, there will also be friction between the load-bearing beam and the detection block when the load-bearing beam moves on the rotating shaft, causing the load-bearing beam to be inconvenient to move. Therefore, in view of the above problems, a load-bearing detection device for elevator detection is proposed. Utility Model Content
