Problems solved by technology

[0002] In the existing technology, when the roadheader works in a large-slope underground roadway, it needs to use external force to climb and descend the slope, and the efficiency is low and the safety factor is small
There must be a special person to control the remote winch, the independent performance of the roadheader is poor, and the efficiency is low. In addition, the traction device must be installed separately on the roadheader, which is poor in operability

Embodiment Construction

[0023] With reference to the accompanying drawings, it is an embodiment of the present invention. The EBZ160 roadheader is selected. On the console of the roadheader 1, the control valve group 2 of the auxiliary traction mechanism 3 of the hydraulic winch is connected by riveting and bolts. Bolts are connected to the connecting bottom plate 5 of the traction mechanism, the base 6 of the winch is installed on the connecting bottom plate 5, the hydraulic winch 7 is connected to the base 6 through bolts, and one end of the fixing frame 8 is connected to the roadheader 4 and the fixing frame 8 by riveting and bolting. The other end is connected on the connection bottom plate 5 of the traction mechanism by riveting and bolts. One end of the hydraulic winch wire rope 9 is fixed on the side of the underground roadway.

[0024] The hydraulic source of the hydraulic winch auxiliary traction device is connected with the roadheader 1 .

Abstract

The invention relates to an excavator provided with an auxiliary traction device of a hydraulic winch. A console of the excavator is connected with a control valve group of an auxiliary traction mechanism of the hydraulic winch; the rear part of the excavator is connected with a connecting bottom plate of the traction mechanism; a bottom seat of the winch is arranged on the connecting bottom plate; the hydraulic winch is connected onto the bottom seat; one end of a fixed frame is connected with a conveyor of the excavator and the other end thereof is connected with the connecting bottom plateof the traction mechanism; and one end of a steel wire rope of the hydraulic winch is fixed on the side wall of an underground tunnel or the bottom plate. The excavator can realize independent operation in large-gradient laneway, reduce labor intensity, improve working efficiency and improve excavating speed.

Description

technical field [0001] The invention relates to a roadheader, in particular to a roadheader equipped with a hydraulic winch auxiliary traction device. Background technique [0002] In the prior art, when the roadheader works in a large-slope underground roadway, it needs external force to realize climbing and descending, and the efficiency is low and the safety factor is small. There must be a special person to control the remote winch, the independent performance of the roadheader is poor, and the efficiency is low. In addition, the traction device must be installed separately on the roadheader, which is poor in operability. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a roadheader equipped with a hydraulic winch auxiliary traction device, which can realize the autonomous operation of the roadheader in a roadway with a large slope, reduce labor intensity, improve work efficiency, and increase tu...
