Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 and figure 2 As shown, an advanced hydraulic support that can automatically walk in a straight line includes a supporting top beam 1;
[0027] The first extension device 11 and the second extension device 13 that are telescopic to the support top beam 1 are respectively provided on both sides of the support top beam 1; wherein the ends of the first extension device 11 and the second extension device 13 are hinged respectively A side guard board 12 and a second side board 14; the first extension device 11 and the first side board 12 and the first side board 12 and the second side board 14 are respectively connected with several telescopic cylinders 15 Hinged at both ends. Specifically, the first extension device 11 and the second extension device 13 and the supporting top beam 1 are respectively equipped wit...

The invention discloses a forepoling hydraulic support capable of automatically linearly walking. The forepoling hydraulic support capable of automatically linearly walking comprises a supporting topbeam. The two sides of the supporting top beam are provided with a first extension device and a second extension device correspondingly. The end of the first extension device and the end of the secondextension device are hinged to a first face guard and a second face guard correspondingly. The bottom of the support top beam is provided with a plurality of groups of support hydraulic stand columns. The bottoms of each group of support hydraulic stand columns are fixed to the top of a base. The bottoms of the bases are provided with U-shaped grooves containing guide rails. The two side edges ofeach guide rail and the two inner side walls of the corresponding U-shaped groove are symmetrically provided with a plurality of groups of first magnetic poles and second magnetic poles, wherein thefirst magnetic poles and the second magnetic poles are in a mutual suspension state after electrifying. The first magnetic poles are electrically connected with a first controller. The second magneticpoles are electrically connected with a second controller. The forepoling hydraulic support capable of automatically linearly walking has the beneficial effects that the magnetic suspension technology can effectively solve the difficulty of manual dragging, and in the manner of adopting linear motion of a mechanical structure to replace manual dragging to keep linear, it can be more efficiently guaranteed that motion of the bases and the support top beam is always linear.
Description
technical field [0001] The invention relates to the field of mining machinery, in particular to an advanced hydraulic support capable of automatic linear walking. 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 straightened...
