Embodiment Construction
[0010] The core of the present invention is a method for rolling and moving hydraulic supports. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0011] A method for rolling and moving a hydraulic support mainly uses a rolling system fixed on the top beam of the hydraulic support to realize direct moving by changing the contact mode between the top beam and the top plate. Wherein the rolling system is the bright spot of the present invention, and it is the guarantee that this method is carried out smoothly. In this method, the rolling system is fixed on the support top beam through the bolt holes (11) on the fixing plate (6), forming a new supporting whole and playing a supporting role.
[0012] In the method, the upper wheel shaft (7) and the lower wheel shaft (8) of the rolling system are placed in the groove (10). The groove has a certain curvature and can be in close contact with the wheel shaft ...

The invention relates to the field of supporting and protecting in a coal mine roadway and discloses a rolling moving method of a hydraulic bracket. The method is completed by a rolling system in fit with the hydraulic bracket; the rolling system is fixed on a top beam of the hydraulic bracket, sliding friction between the top beam and a top plate is changed to be rolling friction, and the direct moving of the bracket is achieved by rolling effect. According to the method, column lifting and falling steps of the hydraulic bracket are omitted in a bracket moving process, the bracket moving process is simplified, meanwhile adverse effect caused by the longitudinal instability factor of the top plate can be effectively reduced, the supporting and protecting intensity of the hydraulic bracket is improved, the advance speed of a working face is accelerated, and achievement of high yield and high efficiency is facilitated.
Description
technical field [0001] The invention relates to the field of coal mine roadway support and is used for improving the frame moving mode of hydraulic supports. Background technique [0002] With the increase of mine mining depth, the degree of mechanization and automation of mining continues to increase, and the level of comprehensive mechanized mining technology continues to improve. During the mining process of the working face, every time the hydraulic support is moved, the column needs to be lowered and raised frequently. The process is cumbersome, the amount of manual labor increases, and the potential safety hazards increase. In order to give full play to the supporting performance of the support, reduce the process of moving the frame, increase the contact area between the top beam and the roof, and improve the efficiency of the frame moving, it is necessary to improve the moving method of the hydraulic support. Contents of the invention [0003] The invention provid...
