[0002] The high-altitude auxiliary drilling device is a device that sends the down-the-hole drill to the construction area that needs to be high and performs drilling operations at high altitudes. This is especially true for large-section tunnel drilling and expansion construction projects. Large-section tunnels generally use the drilling and expansion method (splitting rod). Since the location of the hole to be drilled is relatively high, it is difficult for the down-the-hole drill to enter the required height, which causes certain inconveniences in construction. At this time, it is necessary to use the high-altitude auxiliary drilling device to assist the down-the-hole drill to achieve the drilling needs.

[0016] The lifting and adjusting structure 2 includes a telescopic cylinder 201 fixed to the inner bottom wall of the high-position drilling platform 1, and the inner bottom wall of the high-position drilling platform 1 is rotatably connected with a bidirectional lead screw 202, and the bidirectional lead screw 202 drives the first mounting block 203 to move toward or away from each other. The external thread of the bidirectional lead screw 202 is connected with the first mounting block 203, and the top of the first mounting block 203 of the bidirectional lead screw 202 is hinged with a lifting frame 204, and the lifting frame 204 is hingedly composed of multiple hinged rods, and the inner top wall of the high-position drilling platform 1 is fixedly connected with a first sliding lead screw 205, and the external sliding lead screw 205 is connected with a second mounting block 206.

[0017] The slope adjustment structure 6 includes a second sliding screw rod 601 fixed inside the moving frame, the second sliding screw rod 601 is externally slidably connected to a translation seat 602, the top of the translation seat 602 is hinged with two support rods 603, and a second hydraulic cylinder 604 is fixedly installed on the top of the moving frame. The second hydraulic cylinder 604 pushes the translation seat 602, and the translation seat 602 drives the support rod 603 to swing and support the slope panel to tilt and swing.

[0018] When implementing, follow these steps: 1) First, the down-the-hole drill is fixedly installed on the top plate 102 of the high-position drilling platform 1, and the screw motor 4 is started according to the required drilling height; 2) Then the symmetrical threaded rings of the bidirectional lead screw 202 drive the first mounting block 203 to move relative to or away from each other, thereby driving the lifting frame 204 to deform, so that the top plate 102 can be raised; 3) According to the height of the top plate 102, the second hydraulic cylinder 604 is activated, and the translation seat 602 is pushed to move to the left, so that the support rod 603 swings at an angle; 4) Finally, after the slope plate of the inclined platform 5 is horizontally aligned with the top plate 102, the high-position drilling platform 1 and the inclined platform 5 are locked and assembled through the sleeve, connecting column and fixing bolt structure. At this time, the first hydraulic cylinder 3 controls the four-legged support to move downward and stand stably on the ground.

[0019] according to Figure 1 and Figure 2 As shown, the high-position drilling platform 1 is composed of a base 101 and a top plate 102. The down-the-hole drill is pushed from the inclined platform 5 to the top of the top plate 102 and fixed to the top plate 102. The top of the top plate 102 is designed with a friction convex layer, which can increase the friction between the installed down-the-hole drill and the installed down-the-hole drill. A hook ring is provided on the left side of the front of the base 101 to facilitate the connection with an excavator and other traction machinery, so that the high-position drilling platform 1 can be moved by walking wheels, and the first hydraulic cylinder 3 is pushed downward to move the four-legged support, so that the high-position drilling platform 1 can stand stably on the ground.

[0020] according to Figure 2 and Figure 2 As shown, the screw motor 4 drives the sprocket to make the two bidirectional screws 202 located on the inner front wall and the inner rear wall of the base 101 rotate synchronously, thereby driving two of the first mounting blocks 203 to move in opposite directions with the other two first mounting blocks 203.

[0021] according to Figure 1 and Figure 3As shown, the second hydraulic cylinder 604 is started to push the translation seat 602 to slide to the left. At this time, the translation seat 602 drives the support rod 603 to tilt and swing, thereby supporting the slope panel to rise until it is horizontally aligned with the top plate 102. The connecting column on the left side of the mobile frame is clamped with the sleeve on the right side of the base 101 in a transverse sliding manner. At this time, the sleeve and the connecting column are fixed with fixing bolts to connect and reinforce the high-position drilling platform 1 and the inclined platform 5.

[0022] To sum up, the high-altitude auxiliary drilling device starts the screw motor 4 to drive the two bidirectional screws 202, and the symmetrical threaded ring layers of the bidirectional screws 202 drive the four first mounting blocks 203 to move relative to or away from each other. At this time, the lifting frame 204 is deformed, and the support top plate 102 changes in height. At this time, the second hydraulic cylinder 604 is controlled, and the second hydraulic cylinder 604 pushes the translation seat 602 to move to the left, and the translation seat 602 drives the support rod 603 to change its angle, and then the inclined platform 5 is lifted through the support rod 603, so that the inclined platform 5 is flush with the top right side of the high-position drilling platform 1, thereby ensuring the driving safety of the down-the-hole drill when the high-position drilling platform 1 is raised and lowered, and the problem that the high-altitude drilling auxiliary device in the above-mentioned background technology requires manual hand-held operation to achieve high-position drilling and is not convenient for automatic adjustment is solved.
