Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] Such as figure 1 with figure 2 As shown, a method for automatic straight-line walking of an advanced hydraulic support includes a supporting roof beam 1; on both sides of the supporting roof beam 1, a first extension device 11 and a second extension device 13 that are telescopic to the supporting roof beam 1 are respectively provided ; Wherein the ends of the first extension device 11 and the second extension device 13 are respectively hinged to the first side protection board 12 and the second side protection board 14; between the first extension device 11 and the first side protection board 12 Several telescopic cylinders 15 are respectively hinged between the second extension device 13 and the second side guard 14 . Specifically, the first extension device 11 and the second extension device 13 and the supporting top beam ...

The invention discloses a method for leading an advanced hydraulic support to automatically walk in a straight line. The advanced hydraulic support comprises a supporting top beam; the two sides ofthe supporting top beam are provided with a first extension device and a second extension device respectively; the end parts of the first extension device and the second extension device are hinged with a first face guard plate and a second face guard plate; the bottom of the supporting top beam is provided with a plurality of groups of supporting hydraulic columns, and the bottom of each group ofsupporting hydraulic columns is fixed on the top of a base; a U-shaped groove for accommodating a guide rail is formed in the bottom of the base; a plurality of groups of first magnetic poles and second magnetic poles which keep mutually suspended after being electrified are correspondingly and symmetrically arranged from the two side edges of the guide rail to the two inner side walls of the U-shaped groove; and the first magnetic poles are electrically connected with a first controller, and the second magnetic poles are electrically connected with a second controller. The magnetic levitation technology effectively solves the difficulty of manual dragging, and meanwhile, a linear motion of a mechanical structure is adopted to replace the way of manual dragging to maintain a straight line, so that the motion of the base and the supporting top beam can be guaranteed to be a straight line all the time more efficiently.
Description
technical field [0001] The invention relates to the field of mining machinery, in particular to a method for automatic straight-line walking of an advanced hydraulic support. Background technique [0002] With the rapid improvement of mechanical automation in fully mechanized mining faces, ventilation, transportation, and mining processes have increasingly large requirements for the size of the two cross-sections. Operability and safety are no longer suitable for the requirements of advanced support for safe and efficient fully mechanized mining work. [0003] In particular, there are two major problems in the current advanced hydraulic support: [0004] 1. The advanced hydraulic support needs manual dragging to move forward, which greatly increases the labor intensity and working time of workers and reduces work efficiency. [0005] 2. Whether it is manually dragged or the existing self-moving advanced hydraulic support, there is a problem that it cannot be automatically ...
