Description

Belt fracture detects and anti-falling device

Technical Field

The utility model belongs to the technical field of bearing protection and specifically relates to a belt fracture detects and anti-falling device.

Background

In laser cutting machine's operational scene, the work piece is mostly the hardware plate spare that has certain thickness, gas weight is great, and there is the ascending transportation demand of going up and down of vertical direction to hardware plate spare in the course of working, this horizontal transportation demand generally adopts as drive mechanism with driving belt driven ball screw, the roller that drives a plurality of parallels through drive mechanism by motor drive is the horizontal motion as drive arrangement to drive the hardware plate spare of placing on the plane that a plurality of rollers are constituteed, because ball screw is a perpendicular lead screw drive shaft for the transmission, if driving belt takes place the fracture in the course of working, the perpendicular lead screw drive shaft can take place to fall, equipment damage and personal injury accident can take place.

To avoid this situation, a protection device for the vertical screw driving shaft is needed, which can automatically detect the broken state of the belt and immediately trigger the vertical screw driving shaft clamping mechanism after the broken signal is triggered, so as to lock the position of the shaft and prevent the shaft from falling down.

Chinese patent with publication number CN208762098U discloses a belt vertical transmission self-locking mechanism, which comprises: the device comprises a conductive device embedded in a transmission belt, a self-locking device arranged on a vertical load mounting seat and a mounting bottom plate. In this way, the utility model discloses perpendicular transmission self-locking mechanism of belt, driving belt through the inside certain width that contains a plurality of bundles of wire cores, the stop round pin, plug-type electro-magnet, the closed circuit that power electric connection formed realizes the self-locking structure, driving belt in case drops, the fracture, it takes place the situation can lead to the circuit disconnection in the twinkling of an eye promptly, electro-magnet and round pin post can be in the twinkling of an eye response, it blocks it in the twinkling of an eye in the load whereabouts, and do the connection that floats between electro-magnet and the round pin post, the round pin post is arranged in the guiding hole, the round pin post that the load whereabouts leads to will not influence electro-magnet itself with the striking of bayonet socket, mechanism overall stability, good safety, electric conductivity is stable. The belt vertical transmission self-locking mechanism with the structure can play a role in locking the vertical screw rod driving shaft to a certain extent, but the electromagnet is in floating connection with the pin column which is arranged in the guide hole, and the vertical screw rod driving shaft can generate rigid collision in the vertical direction when falling, so that the load is limited by the strength of materials, the weight loaded by the laser cutting machine is large, and the belt vertical transmission self-locking mechanism with the structure is difficult to apply.
