Traction device for manual operator of crane

Abstract

The invention discloses a traction device for a manual operator of a crane, and belongs to the technical field of explosion-proof cranes. The traction device comprises the manual operator, a cable, ahorizontal moving component, a horizontal wiring component and a vertical load-bearing component; the horizontal moving component is used for realizing horizontal movement of the traction device; thehorizontal wiring component is connected with the horizontal moving component and is used for mounting the horizontal part of the cable; and the vertical load-bearing component bears the gravity of the manual operator in the vertical direction and is arranged between the horizontal wiring component and the manual operator. The cable is complete and is free of breaking points from horizontal wiringto vertical wiring, so that explosion-proof connectors, explosion-proof junction boxes, explosion-proof gland heads and the like are omitted, the cable is easy to mount, and the cost is reduced effectively; the vertical load-bearing component has the load bearing effect while the cable is mounted, so that the service life of the cable is effectively prolonged; and the device is simple in structure and high in reliability.

Description

technical field [0001] The invention relates to the technical field of explosion-proof cranes, in particular to a traction device for a crane hand operator. Background technique [0002] In the bridge gantry crane industry, the crane hand operator is an important part of the equipment. Since the bridge gantry crane and electric hoist and other equipment are mobile, the operator needs to operate the equipment through the hand operator on the ground, requiring manual operation. The device can not only move with the equipment, but also move along the sliding rails on the equipment under the manual traction of the operator. Under normal circumstances, a cable connector is installed on the traction device of the handheld operator, which allows the cable to have a break point. The flat cable that moves horizontally is converted into a vertical round cable with good load-bearing capacity through the cable connector. The bottom end of the round cable Connect with the handheld. How...

AI Technical Summary

Problems solved by technology

However, in an explosion-proof environment, the cable joint is not allowed to directly expose the breakpoint, and special processes are required, such as using explosion-proof connectors, explosion-proof junction boxes or explosion-proof glands, etc., which are large in size and expensive, resulting in a large traction device. , the cost is high, and it is not easy to install. At the same time, the weight of the explosion-proof handheld operator in the explosion-proof environment is about 10 times that of the ordinary handheld operator. , causing the cable to bear a large load in the vertical direction and easy to be damaged, which greatly reduces the service life of the cable
