Remote-control air-pressure braking cable crane roadster

Abstract

The invention discloses a remote-control air-pressure braking cable crane roadster. The remote-control air-pressure braking cable crane roadster comprises a vehicle body, as well as a traveling pulley, a hoisting pulley and a hoisting rope guide pulley which are fixedly mounted in the vehicle body, wherein a remote-control interlocking air-pressure brake and a working power supply are also mounted in the vehicle body; the remote-control interlocking air-pressure brake comprises a pneumatic control system, a bearing rope brake and a hoisting rope brake; the pneumatic control system comprises an air supply device, an overflow valve, a pressure-reducing valve, a two-position four-way pneumatic control reversing valve, a speed-adjusting valve, an electromagnetic wave remote-control switch and a two-position three-way electromagnetic valve; the air supply device comprises an inflation system and/or a pressure air tank; the inflation system comprises an air compressor, an air filter, an air dryer and an oil sprayer; the bearing rope brake adopts horizontal transverse clamping brake on a bearing rope. By the remote-control air-pressure braking cable crane roadster, interlocking brake of the bearing rope and the hoisting rope can be realized; the bearing rope is braked by a cylinder overhead double-connecting-rod reinforcement horizontal transverse clamping mechanism, so that the roadster has a function of passing a bearing rope middle bracket.

Description

technical field [0001] The invention belongs to the technical field of cable cranes, and in particular relates to a cable crane racing car with remote control air pressure braking. Background technique [0002] Cable cranes are widely used in cargo handling operations in mines, docks, freight yards, etc., and are also used in logging operations in forestry logging areas. The sports car is an important equipment used by the cable crane for lifting and transporting materials, and its function determines the mobility and work efficiency of the cable crane. At present, the sports cars used in general cable cranes are non-intelligent sports cars, that is, the sports cars do not have the function of autonomous braking of the load-bearing cables and hoisting cables. Therefore, most of the general cable cranes use a three-cable cable system with separate load cables, hoisting cables, and traction cables, which not only complicates the power winch system and cable system of the cabl...

AI Technical Summary

Problems solved by technology

Therefore, most of the general cable cranes use a three-cable cable system with separate load cables, hoisting cables, and traction cables, which not only complicates the power winch system and cable system of the cable crane, but also adds trouble to the installation of the cables. , especially for the logging operations of forest skidding cable cranes that have to frequently transfer the operation area, which restricts the application of cable cranes in forest harvesting production to a certain extent
