Embodiment Construction

[0019] See attached Figure 1-2 , which describes a preferred embodiment of the coal mine filling hydraulic double-track hoisting locomotive according to the present invention. The hydraulic double-track hoisting locomotive for filling underground coal mines includes two I-steel rails, a mine car suspended on the rails and a PLC controller; The two ends of the cross-shaped steel track are respectively provided with a first fixed end and an end fixed end to prevent the mine car from falling out. A mine car is suspended on each I-shaped steel track, and the mine car is suspended on the I-shaped steel track by a carrying trolley. The carrying trolley includes walking rollers and guide rollers, and the traveling rollers are arranged symmetrically along the track, preferably 8, each There are 4 sides, and the walking rollers are respectively set at the upper and lower ends of the edge of the I-shaped steel track, which are used to carry the mine car and make the mine car move alon...

Abstract

The invention provides an underground coal mine hydraulic filling double track lifting locomotive, which comprises two I-steel tracks, a mine car hanged on the track and a PLC controller; The two I-steel tracks are arranged paralleled and are suspended on the top board by an anchor pole, and each I-steel track is suspended with the mine car, and the mine car is suspended on the I-steel track by a bearing dolly; the mine car is connected with a wire rope by a traction mechanism, and one end of the wire rope is connected to the mine car, and the other end is connected to a hydraulic station by a directive wheel and a friction wheel, and the friction wheel is driven by a low speed large torque motor; the hydraulic station is an enclosed system comprising a variable pump and a quantitative motor for realizing constant power speed regulation, and the quantitative motor is provided with a speed sensor for detecting the rotating speed of the quantitative motor, and the PLC controller is used for controlling the operation of the mine car by the rotating speed which is detected by the speed sensor.

Description

technical field [0001] The invention relates to a coal mine filling hydraulic double-track hoisting locomotive and a control system for hydraulically controlling the hoisting locomotive. Background technique [0002] Underground coal mine filling is to backfill coal mine gangue into the goaf to reduce surface subsidence and realize green coal mining. This is the development direction of coal mining in the future. [0003] The existing filling method is to lay tracks on the floor, and use mine cars or other vehicles to transport coal gangue. The cost of laying tracks is high, and it takes up underground space, so it cannot be implemented in many narrow working faces. More importantly, ground rails cannot be laid near the goaf. Therefore, after the coal gangue is transported underground, it is necessary to use other means of transportation, and even use manual lifting to fill the goaf. Not only the filling efficiency is low, but also safety accidents are prone to occur, serio...
