A traction wire rope protection device for air rides

Abstract

The invention discloses a traction wire rope protection device for air vehicles. The traction wire rope passes through the passage of the traction wire rope. The traction wire rope is provided with several air vehicles along the direction of transporting personnel. Each air vehicle passes through the positioning bracket and the traction The wire ropes are connected, and the traction wire rope protection device includes a broken rope catching mechanism, a traction protection mechanism, a programmable logic controller PLC and a central control machine, and the programmable logic controller PLC communicates with the central control machine through industrial Ethernet, and the broken rope catching mechanism includes a tension The sensor and the gripping device arranged on one side of the traction wire rope channel, the tension sensor is connected with the traction wire rope, the tension sensor is connected with the programmable controller PLC, the traction protection mechanism includes a protective shell and a driving motor, the protective shell is connected with the gripping device, and the driving The motor is connected with the grip device through a linkage assembly. The invention can not only capture the broken steel wire rope in time, but also form secondary protection for the steel wire rope, avoiding the occurrence of secondary accidents.

Description

technical field [0001] The invention relates to a wire rope protection device, in particular to a traction wire rope protection device for aerial vehicles. Background technique [0002] The air ride device is used alone or in conjunction with other auxiliary transportation equipment, and is widely used in coal mine production. The aerial ride-on device is mainly used for transporting coal miners up and down, reducing the physical exertion of the workers and improving the work efficiency of the workers. Accidents of broken ropes of aerial vehicles have occurred frequently in recent years, and even casualties have occurred. [0003] At present, the existing air passenger protection devices mainly have the following problems: first, the broken rope catcher malfunctions. During normal operation, often due to some mechanical reasons, the broken rope catcher makes a wrong action, or even malfunctions. In the case of frequent movements, this has a serious impact on the normal pro...

Problems solved by technology

[0003] At present, the existing air passenger protection devices mainly have the following problems: first, the broken rope catcher malfunctions. During normal operation, often due to some mechanical reasons, the broken rope catcher makes a wrong action, or even malfunctions. In the case of frequent movements, this has a serious impact on the normal production process; secondly, because the catching action of the broken rope catcher is completed in an instant, when this action is completed, an instant momentum will be generated, which will damage the injured. The steel wire rope causes secondary damage, which leads to secondary accidents; finally, only one capture with the broken rope catcher cannot guarantee the effect of the 100% care-taking action, and after the accident, it is impossible to accurately determine the location near the broken wire rope. The specific location of the staff cannot provide effective information for rescue, which is not conducive to rescue
