The clamping plate 82 can be clamped and fixed by the arrangement of the plug rod 84 and the slot 83, so as to facilitate the installation and disassembly of the rock drill body 7.

[0028] Support plates 851 are provided at both ends of the opposite side of the translation plate 85, and the bottom of the support plate 851 is fixedly mounted on the outer wall of the mounting plate 81. The support plate 851 and the translation plate 85 are elastically connected by a first telescopic spring 852 respectively. The position of the translation plate 85 can be adjusted and restored by the setting of the first telescopic spring 852.

[0029] The fastening assembly 9 includes an extrusion block 91 arranged at the bottom of the second electric slider 6 and a threaded rod 92 movably installed on one side of the extrusion block 91, and the two sides of the extrusion block 91 are respectively fitted with the opposite side of the trapezoidal block 87, a straight plate 93 is arranged on one side of the extrusion block 91, and the bottom of the straight plate 93 is fixedly mounted on the outer wall of the outer side of the mounting plate 81, and the end of the threaded rod 92 away from the extrusion block 91 is threadedly extended to the outside of the straight plate 93, and the end of the threaded rod 92 away from the extrusion block 91 is fixedly mounted with a knob 94, and the position of the extrusion block 91 can be adjusted by setting the threaded rod 92, so as to facilitate the development of the clamping work.

[0030] A limiting telescopic rod 911 is fixedly installed on the other side of the extrusion block 91, and a vertical plate 912 is fixedly installed at the output end of the limiting telescopic rod 911. The bottom of the vertical plate 912 is fixedly installed on the outer wall of the mounting plate 81. The setting of the limiting telescopic rod 911 can play a guiding and limiting role in the movement of the extrusion block 91.

[0031] A plurality of blind holes 941 are provided at equal intervals on the outside of the knob 94, and a positioning rod 942 is inserted into the inner cavity of one of the blind holes 941, a pulling plate 943 is fixedly installed on the end of the positioning rod 942 away from the knob 94, a side plate 944 is provided on the side of the pulling plate 943 away from the knob 94, and the pulling plate 943 and the side plate 944 are elastically connected by a second telescopic spring 945. The positioning rod 942 and the blind hole 941 can be provided to limit the knob 94, and the second telescopic spring 945 can be provided to adjust and restore the position of the positioning rod 942.

[0032] Specifically, when in use, the gantry 1 can be placed at the position where rock drilling is required. After the placement is completed, the vertical direction of the rock drill body 7 can be adjusted by setting the first electric slide rail 2 and the first electric slider 3, and the horizontal direction of the rock drill body 7 can be adjusted by setting the second electric slide rail 5 and the second electric slider 6. Then, the rock drilling work can be carried out by the operation of the rock drill body 7. The rock drill body 7 can be disassembled and replaced when it is damaged due to long-term use, and the pulling plate 943 is pulled. When the pulling plate 943 moves, it squeezes the second telescopic spring 945, and at this time, it also drives the positioning rod 942 away from the inner cavity of the blind hole 941, and then Turning the knob 94 drives the threaded rod 92 to rotate. When the threaded rod 92 rotates, it drives the extrusion block 91 to move forward under the action of the limiting telescopic rod 911. When the extrusion block 91 moves forward, it squeezes the trapezoidal blocks 87 on both sides. At this time, the trapezoidal blocks 87 will move in the opposite direction and squeeze the first telescopic spring 852. When the trapezoidal blocks 87 move in the opposite direction, they will drive the translation plate 85 to move in the opposite direction through the fixing rod 86. At this time, the insertion rod 84 can be driven to move in the opposite direction to keep it away from the inner cavity of the slot 83. Then, the rock drill body 7 is moved downward to drive the clamping plate 82 away from the mounting plate 81, thereby completing the disassembly of the rock drill body 7. Otherwise, it can be re-clamped and fixed. Example

[0033] See also Figure 1 - Figure 2 Fixed plates 11 are fixedly installed on both sides of the bottom of the gantry 1. The setting of the fixed plates 11 can adjust the grounding area of ​​the gantry 1 when it is placed.

[0034] An L-shaped bearing plate 61 is fixedly installed at the bottom of the second electric slider 6, and the rear side of the inner side of the L-shaped bearing plate 61 is fixedly installed on the outer wall of one side of the mounting plate 81. The setting of the L-shaped bearing plate 61 can support and fix the mounting plate 81.

[0035] Specifically, the setting of the fixed plate 11 can support and place the gantry 1, and the setting of the L-shaped bearing plate 61 can support and fix the mounting plate 81. When the second electric slide rail 5 and the second electric slider 6 are in operation, the mounting plate 81 can be driven to move left and right by the L-shaped bearing plate 61, thereby facilitating the adjustment of the horizontal position of the rock drill body 7.

[0036] In summary: when in use, the gantry 1 can be placed at the position where rock drilling is required. After placement, the vertical direction of the rock drill body 7 can be adjusted by setting the first electric slide rail 2 and the first electric slider 3, and the horizontal direction of the rock drill body 7 can be adjusted by setting the second electric slide rail 5 and the second electric slider 6. Then, the rock drilling work can be carried out by the operation of the rock drill body 7. The rock drill body 7 can be disassembled and replaced when it is damaged due to long-term use, and the pulling plate 943 is pulled. When the pulling plate 943 moves, it squeezes the second telescopic spring 945, and at this time, it also drives the positioning rod 942 away from the inner cavity of the blind hole 941, and then The rotatable knob 94 drives the threaded rod 92 to rotate. When the threaded rod 92 rotates, it drives the extrusion block 91 to move forward under the action of the limiting telescopic rod 911. When the extrusion block 91 moves forward, it squeezes the trapezoidal blocks 87 on both sides. At this time, the trapezoidal blocks 87 will move in the opposite direction and squeeze the first telescopic spring 852. When the trapezoidal blocks 87 move in the opposite direction, they will drive the translation plate 85 to move in the opposite direction through the fixed rod 86. At this time, the insertion rod 84 can be driven to move in the opposite direction to move it away from the inner cavity of the slot 83. Then, the rock drill body 7 is moved downward to drive the clamping plate 82 away from the mounting plate 81, thereby completing the disassembly of the rock drill body 7. Otherwise, it can be re-clamped and fixed.
