Description

Technical Field

[0001] The invention belongs to the technical field of rock crushing, and in particular relates to a rock seam forming and crushing device and method. Background Art

[0002] In various operations such as mining, tunneling, and roadway construction, we often face a whole surface of rock. Since we need to hollow out the inside of the mountain, there is no free surface relative to the crushing direction, which causes great difficulties in construction. Construction methods such as explosives and hammer rock drilling have various disadvantages. Therefore, the existing technology often adopts the process of milling and drilling first and then squeezing and crushing to achieve rock seam crushing to overcome the above problems. However, the equipment currently required to achieve the above rock seam crushing includes drilling devices, cutting machines, extrusion crushers, etc. Various equipment needs to be used alternately to achieve seam crushing, which has the problems of cumbersome equipment replacement, inconvenient operation, and low processing efficiency.

[0029] The mechanical arm 2 includes a boom 21, a boom swing cylinder 22, a combined arm 23, and a combined arm swing cylinder 24. One end of the boom 21 is connected to the body of the wheeled excavator 1 through an articulated seat, and both ends of the boom swing cylinder 22 are respectively articulated to the body of the wheeled excavator 1 and the boom 21. One end of the combined arm 23 is connected to the boom 21 through an articulated seat, and both ends of the combined arm swing cylinder 24 are respectively articulated to the boom 21 and the combined arm 23. When the mechanical arm 2 is in use, it can drive the double track 5 and the structures above it to move up, down, left, and right to facilitate the seam making and crushing work.

[0030] The transverse mechanism 3 and the lifting mechanism 4 are both provided in two and are respectively provided in the embedded grooves at both ends of the combined arm 23. The lifting mechanism 4 drives the transverse mechanism 3 to move up and down through the bracket, and the transverse mechanism 3 drives the double track 5 to move horizontally. The transverse mechanism 3 and the lifting mechanism 4 are both movable cylinders.

[0031] The double track 5 includes two H-shaped steel tracks arranged side by side, and the bottom of one end of the two H-shaped steel tracks is fixedly connected to the transverse movement mechanism 3 through a bracket.

[0032] The No. 1 driving mechanism 6 includes a No. 1 walking trolley 61, a driving wheel 62 and a driving motor 63. The driving wheel 62 is installed on the No. 1 walking trolley 61. The output shaft of the driving motor 63 is connected to the driving wheel 62. The driving wheel 62 is driven to rotate to drive the No. 1 walking trolley 61 to move on the upper surface of the H-shaped steel track. The water jet gun 7 is fixed to the No. 1 walking trolley 61 through a clamp. The water jet gun 7 is connected to the water jet supercharger 10 through a pipeline. The water jet supercharger 10 is installed on the wheeled excavator 1.

[0033] When the No. 1 driving mechanism 6 is in use, the driving motor 63 drives the No. 1 walking trolley 61 to move through the driving wheel 62, and then drives the water jet gun 7 on the No. 1 walking trolley 61 to move horizontally, the transverse mechanism 3 drives the water jet gun 7 to move horizontally forward and backward, and the lifting mechanism 4 drives the water jet gun 7 to move up and down. The No. 1 driving mechanism 6, the transverse mechanism 3 and the lifting mechanism 4 cooperate to achieve the adjustment of the position of the water jet gun 7 in the drill hole, that is, to achieve all-round cutting work of the water jet gun 7.

[0034] The No. 2 driving mechanism 8 includes a No. 2 traveling trolley 81 and a multi-stage cylinder 82. One end of the multi-stage cylinder 82 is fixedly mounted on the H-shaped steel track, and the other end is fixedly connected to the No. 2 traveling trolley 81. The extrusion crusher 9 is fixed to the No. 2 traveling trolley 81 by a clamp.

[0035] When the No. 2 driving mechanism 8 is in use, the multi-stage cylinder 82 drives the extrusion crusher 9 to move horizontally through the No. 2 walking trolley 81, the transverse movement mechanism 3 drives the extrusion crusher 9 to move horizontally forward and backward, and the lifting mechanism 4 drives the extrusion crusher 9 to move up and down. The No. 2 driving mechanism 8, the transverse movement mechanism 3 and the lifting mechanism 4 cooperate to achieve the adjustment of the position of the extrusion crusher 9 in the drill hole, that is, to achieve the all-round air surface excavation work of the extrusion crusher 9.

[0037] The arrangement of the No. 1 traveling trolley 61 and the No. 2 traveling trolley 81 not only serves as the drive for the water jet gun 7 and the extrusion crusher 9, but also enables the two to move stably on the double track 5. The rollers fit with the upper surface of the H-shaped steel track and the upper groove wall of the track groove to ensure that the water jet gun 7 and the extrusion crusher 9 move smoothly, and the side walls of the frame 11 are clamped on the side surfaces of the H-shaped steel track, so that the water jet gun 7 and the extrusion crusher 9 will not shake, thereby ensuring the quality of the inclined groove and the air surface.

[0038] The present invention also provides a rock cracking and crushing method, comprising the following steps:

[0039] S1. After the rock drilling trolley drills the rock, the wheeled excavator 1 is used to drive the water knife gun 7 to move to the drilling station. The traverse mechanism 3, the lifting mechanism 4 and the first drive mechanism 6 cooperate to drive the water knife gun 7 to move three-dimensionally and omnidirectionally to cut an oblique groove between adjacent drill holes.

[0040] S2. The wheeled excavator 1 is used to drive the crushing and squeezing gun to move to the bevel cutting station. The transverse movement mechanism 3, the lifting mechanism 4 and the second driving mechanism 8 cooperate to drive the crushing and squeezing gun to move in three dimensions and in all directions, and an open face is opened at the bevel cutting location. Subsequently, a special crusher equipment is used to squeeze the rock and open the heading face.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
