Translational composite beam bearing mechanism

Abstract

The invention discloses a translational composite beam bearing mechanism, and belongs to the technical field of mine lifting protection devices. Two oppositely disposed driving lead screws are mountedon a base, and driving mechanisms are connected to one ends of the driving lead screws; the two ends of a retaining beam and a synchronous retaining beam are correspondingly connected to the two driving lead screws by threads, and bosses and rabbets which are correspondingly arranged on the inner side faces, opposite to each other, of the retaining beam and the synchronous retaining beam in a machine mode; and a catching device is further installed in the retaining beam in an embedded mode, and a plug corresponding and opposite to the catching device is fixed to the inner side of the synchronous retaining beam. The translational composite beam bearing mechanism has simple structure and high feasibility, and avoids the situation that a supporting structure needs to be arranged additionallywhen a single bearing beam or two beams existing in existing equipment are stressed; and in the case of rope sliding and car sliding, a composite beam can quickly and accurately place a steel wire rope in the catching device through the driving lead screws, no mechanical malfunction occurs, the effect of stress is good under the larger lifting load, and the reliability is high.

Description

technical field [0001] The invention relates to a mining hoisting rope arresting, rope adjusting, and rope clamping device, in particular to a translational composite beam receiving mechanism, which belongs to the technical field of mine hoisting protection devices. Background technique [0002] In vertical shaft hoisting operations, accidents of sliding ropes and cars often occur. Once the consequences are very serious, sliding ropes and cars have become major accident hazards that restrict mine production and affect safety. At present, the sliding rope and car sliding protection device for the friction lifting system are basically a single beam or a pair of beams, with a rope clamping mechanism, and a separate support structure is adopted at the bottom of the beam to carry out the arrest action. The strength requirements are high, and during the catching action, it is easy for the steel wire rope to enter the rope mouth slowly, the catching action is delayed, the force of ...

[0002] In vertical shaft hoisting operations, accidents of sliding ropes and vehicles often occur. Once they occur, the consequences are very serious. Sliding ropes and vehicles have become major accident hazards that restrict mine production and affect safety.

At present, the sliding rope and car sliding protection device for the friction lifting system are basically a single beam or a pair of beams, with a rope clamping mechanism, and a separate support structure is adopted at the bottom of the beam to carry out the arrest action. The strength requirements are high, and during the capture action, it is easy to cause the steel wire rope to enter the rope slowly, the capture action is delayed, the force of the beam is unstable, and the reliability is low.
