Description

Technical Field

[0001] The present application relates to the technical field of elevator equipment, and in particular to a device for inspecting the breakage of a magnetic strip of a steel belt. Background Art

[0002] Elevator leveling refers to the action of making the elevator car sill and the floor door sill reach the same plane when the elevator car approaches the stop station. Elevator operation control requires that the elevator is in a level position when it stops, that is, the floor of the car is level with the floor of the stop floor to facilitate entry and exit.

[0003] At present, various steel belt magnetic strips are used for connection in elevator equipment systems. The floor is usually determined by detecting the magnetic strips. In order to ensure accurate detection, the magnetic strips need to be tightened and checked in real time to see if they are broken. The traditional method of directly hanging heavy objects is prone to falling when the magnetic strips break. By using a tension spring that is always in a stretched state, this can easily lead to elastic failure. Utility Model Content

[0033] The limiting plate 120 is provided with a slide groove 121 , and the connecting plate 130 slides through the slide groove 121 . The slide groove 121 is provided to pass through the connecting plate 130 and guide the connecting plate 130 to move.

[0034] Among them, the locking part 150 includes a locking nut 151, a locking bolt 152 and a locking plate 153. The locking bolt 152 passes through the locking plate 153 and the connecting plate 130. The locking nut 151 is threadedly connected to the locking bolt 152. The end of the magnetic strip body 140 is pressed between the locking plate 153 and the connecting plate 130. By setting the locking nut 151, the locking bolt 152 and the locking plate 153, the locking nut 151 and the locking bolt 152 are tightened, so that the locking plate 153 presses and fixes the magnetic strip body 140 to connect, which is convenient for repeated installation and connection during maintenance.

[0035] In a specific implementation scheme, the counterweight 160 includes a hanging frame 161 and a weight block 162. The hanging frame 161 is installed at the bottom end of the connecting plate 130, and the weight block 162 is arranged in the hanging frame 161. By setting the hanging frame 161 and the weight block 162, and adopting the method of hanging the hanging frame 161 to hang the weight block 162, it is convenient to replace different weight blocks 162 according to needs.

[0037] It should be noted that an extension plate 111 is vertically arranged at the end of the mounting plate 110, and both the mounting plate 110 and the extension plate 111 are provided with mounting holes. By setting the vertical extension plate 111 and providing mounting holes, adaptive installation in different positions can be performed according to the actual installation environment, which has higher applicability.

[0041] The working principle of the inspection device for the broken magnetic strip of steel strip is as follows: during use, when the magnetic strip body 140 breaks, the weight block 162 drives the hanging frame 161 to fall, the hanging frame 161 drives the connecting plate 130 to fall, the connecting plate 130 slides down along the slide groove 121 of the limit plate 120, the connecting plate 130 drives the magnetic strip body 140 and the locking member 150 to slide down, the connecting plate 130 drives the inspection inclined plate 210 to contact the trigger head of the low-voltage inspection switch 220, so that the car stops moving, and the locking member 1 50 moves down and abuts against the top of the limit plate 120, so that the connecting plate 130 and the counterweight 160 do not continue to fall, thereby effectively preventing the counterweight 160 from falling and hitting other objects when the magnetic strip body 140 breaks. Tighten the locking nut 151 and the locking bolt 152, so that the locking plate 153 presses and fixes the magnetic strip body 140 to connect, which is convenient for repeated installation and connection during maintenance. The method of using the hanging frame 161 to hang the weight block 162 is convenient for replacing different weight blocks 162 as needed.
