Description

Technical Field

[0001] This invention relates to the field of coal mining, and more specifically, to a propulsion device for an impact drill. Background Technology

[0002] Impact drills are mainly used for impact drilling into concrete floors, concrete walls, and some stone materials. In construction projects in spacious areas and renovation projects in tall buildings, it is necessary to impact drill into ceilings and wall panels to fix suspended ceilings and install light fixtures.

[0003] In related technologies, drilling is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] In related technologies, the method of impact drilling involves construction workers climbing onto high working platforms such as A-frame ladders or scaffolding to hold an impact drill. It is difficult to use the correct force to press the impact drill, resulting in high physical exertion, low drilling efficiency, and the risk of falling from a height. The reason for these disadvantages and problems is that drilling requires pressing the impact drill with force, which is not suitable for exerting force while standing on an A-frame ladder or scaffolding. Thus, when drilling deeper holes, the operator needs to press the impact drill for a long time, resulting in excessive physical exertion and reduced drilling efficiency.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of the present invention provide a propulsion device for an impact drill that facilitates drilling and reduces the labor intensity of construction workers.

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] The propulsion device of an impact drill according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] like Figure 1-8 As shown, the propulsion device 100 of the impact drill according to an embodiment of the present invention includes a transport vehicle 1, a support assembly 2, a rotating assembly 3, a first mounting base 4, and a drilling assembly 5.

[0037] Support assembly 2 is mounted on transport vehicle 1 so that transport vehicle 1 can move support assembly 2. Support assembly 2 can move relative to transport vehicle 1 in the width direction of transport vehicle 1 (e.g., ...). Figure 1 (As shown in the front-back direction) can rotate. Specifically, as... Figure 1-2 As shown, the right end of the support component 2 is mounted on the transport vehicle 1 and can rotate in the front-to-back direction. Thus, the support component 2 is moved by the transport vehicle 1 and rotates on the transport vehicle 1.

[0038] The rotating component 3 is located at the end of the support component 2 away from the transport vehicle 1, and the rotating component 3 can rotate relative to the support component 2 around the length direction of the transport vehicle 1 (e.g., Figure 1 (As shown in the left and right directions) It can rotate. Specifically, as... Figure 1-2 As shown, the rotating component 3 is located at the left end of the support component 2, thereby allowing the rotating component 3 to be rotatably mounted on the transport vehicle 1 in the left and right directions via the support component 2.

[0039] The first mounting base 4 is located at the end of the rotating assembly away from the support component 2 and is connected to the rotating assembly 3, so that the rotating assembly 3 can drive the first mounting base 4 to rotate around the length of the transport vehicle 1. Specifically, as shown in the figure... Figure 1-2As shown, the first mounting base 4 can extend horizontally, and the first mounting base 4 is located at the left end of the rotating component 3 and is detachably connected to the rotating component 3 (e.g., fastener connection), so that the first mounting base 4 can be rotated in the left and right directions by the rotating component 3.

[0040] Drilling assembly 5 is mounted on the first mounting base 4 and is positioned relative to the length direction of the first mounting base 4 (e.g., ...). Figure 1 The drill assembly 5 (shown in the left-right direction) is movable and used for drilling. Specifically, as shown... Figure 1-2 As shown, the drilling component 5 can perform drilling. The drilling component 5 is located on the left side of the first mounting base 4, and the drilling component 5 can move along the extension direction of the first mounting base 4, so that the drilling component can perform drilling. By rotating the component 3, the first mounting base 4 can be rotated in the left and right directions, thereby adjusting the drilling angle.

[0041] The impact drill propulsion device 100 of this embodiment includes a transport vehicle 1, a support component 2, a rotating component 3, a first mounting base 4, and a drilling component 5. The transport vehicle 1 serves as the fulcrum for propulsion of the drilling component 5, and the base of the transport vehicle 1 is stable. Through the cooperation of the support component 2 and the rotating component 3, the drilling direction of the drilling component 5 can be adjusted, thereby improving the drilling efficiency. It eliminates the need for construction personnel to perform impact drill 53 drilling operations on a high working platform, reducing the workload of construction personnel.

[0042] In some embodiments, the rotating assembly 3 includes a second mounting base 31, a first motor 32, a turntable 33, a first mounting plate 34, and a second mounting plate 35.

[0043] One end of the second mounting base 31 is connected to the support assembly 2, and the second mounting base 31 is rotatable relative to the support assembly 2 about the width of the transport vehicle 1. Specifically, as shown... Figure 3-5 As shown, the second mounting base 31 includes a first vertical plate 311, a second vertical plate 312, and a third vertical plate 313. The first vertical plate 311 and the second vertical plate 312 extend in the left-right direction and are arranged in parallel at intervals in the front-back direction. The third vertical plate 313 is a circular plate and is fixed to one end of the first vertical plate 311 and the second vertical plate 312. The first vertical plate 311 and the second vertical plate 312 are both hinged to the other end of the support assembly 2, thereby allowing the second mounting base 31 to rotate around the front-back direction at the left end of the support assembly 2.

[0044] The first motor 32 is housed within the second mounting base 31. A turntable 33 is located at the end of the second mounting base 31 furthest from the support assembly 2, and the first motor 32 passes through the mounting base and is connected to the turntable 33. A first mounting base 4 is located on the side of the turntable 33 furthest from the second mounting base 31 and is mounted on the turntable 33, so that the first motor 32 drives the first mounting base 4 to rotate via the turntable 33. Specifically, as... Figure 3-5As shown, the base of the first motor 32 is fixedly installed between the first vertical plate 311 and the second vertical plate 312. The turntable 33 is rotatably disposed at one end of the second mounting base 31 (i.e., the end of the third vertical plate 313 facing away from the first motor 32). The drive end of the first motor 32 passes through the third vertical plate 313 and is connected to the turntable 33. Thus, the first motor 32 drives the turntable 33 to rotate in the left and right directions, thereby enabling the first motor 32 to provide power to the turntable 33.

[0045] The first mounting plate 34 and the second mounting plate 35 are both located on the side of the turntable 33 adjacent to the first motor 32 and are both connected to the turntable 33. One end of the second mounting bracket is located inside the first cavity and the second cavity, so that the turntable 33, the first mounting plate 34, and the second mounting plate 35 are rotatably mounted on the support assembly 2 via the second mounting base 31. Specifically, as shown... Figure 3-5 As shown, both the first mounting plate 34 and the second mounting plate 35 are semi-circular annular plates located to the left of the turntable 33. Stepped holes are provided on the right end faces of both the first mounting plate 34 and the second mounting plate 35, located on their inner circumferential surfaces. The stepped holes of the first mounting plate 34 and the turntable 33 define a first cavity, and the stepped holes of the second mounting plate 35 define a second cavity. The front half of the third vertical plate 313 is located within the first cavity, and the rear half of the third vertical plate 313 is located within the second cavity, thereby enabling… The third vertical plate 313 is disposed between the first mounting plate 34 and the turntable 33, and between the second mounting plate 35 and the turntable 33. The outer peripheral surface of the third vertical plate 313 can be spaced apart from the inner peripheral surfaces of the first cavity and the second cavity (in other words, there is a gap between the third vertical plate 313 and the first cavity and the second cavity, which allows the first mounting plate 34, the second mounting plate 35 and the turntable 33 to rotate relative to the third vertical plate 313 in the left and right directions). Thus, the turntable 33 can be mounted on the second mounting base 31 through the first mounting plate 34 and the second mounting plate 35.

[0046] In some embodiments, the rotating assembly 3 further includes a first clamping plate 36 and a second clamping plate 37, which are disposed on the side of the turntable 33 away from the first motor 32. The first clamping plate 36 and the second clamping plate 37 are arranged in parallel at intervals to form a clamping cavity, and the side of the first mounting base 4 away from the drilling assembly 5 is disposed within the clamping cavity. Specifically, as shown... Figure 3-6 As shown, the first clamping plate 36 and the second clamping plate 37 are fixed (e.g., welded) to the right side of the turntable 33. The first clamping plate 36 and the second clamping plate 37 are both horizontal plates and are arranged opposite each other in the vertical direction to form a clamping cavity. The left side of the first mounting base 4 is provided with a protrusion extending in the front-back direction. The protrusion can pass through the clamping cavity and is sequentially passed through the first clamping plate 36, the protrusion and the second clamping plate 37 by fasteners, so that the first mounting base 4 can be detachably installed on the first clamping plate 36 and the second clamping plate 37.

[0047] In some embodiments, the first clamping plate 36 includes a first segment 371 and a second segment 362 connected to each other, and the second clamping plate 37 includes a third segment 371 and a fourth segment 372 connected to each other, the first segment 371 and the third segment 371 being radially connected to the turntable 33 (e.g., ...). Figure 1 Extending in the forward and backward direction (as shown), the second segment 362 and the fourth segment 372 extend along the axial direction of the turntable 33 (as shown). Figure 1 Extending in the left-right direction (as shown), the first segment 371 and the third segment 371 are arranged in parallel with intervals to form a first clamping sub-cavity, and the second segment 362 and the fourth segment 372 are arranged in parallel with intervals to form a second clamping sub-cavity. The first mounting base 4 can be disposed in one of the first clamping sub-cavity and the second clamping sub-cavity. Specifically, as shown... Figure 3 and Figure 6 As shown, the first segment 371 and the third segment 371 extend in the front-to-back direction and are fixed to the right side of the turntable 33. The third segment 371 and the fourth segment extend in the left-to-right direction and are fixed to the side of the first vertical plate 311 of the first mounting base 4, such that the extension direction of the first segment 371 intersects the extension direction of the second segment 362 at a 90° angle. In other words, the first clamping plate 36 and the second clamping plate 37 are both L-shaped. The first segment 371 and the third segment 371 are spaced apart in the vertical direction to form the first clamping cavity. The second segment 362 and the fourth segment 372 are on the upper... The first clamping cavity is formed by spacing the first clamping cavity and the second clamping cavity are connected. The extension directions of the first clamping cavity and the extension directions of the second clamping cavity intersect at 90°. When it is necessary to drill holes in the top or bottom plate of the tunnel, the first mounting base 4 can be installed in the first clamping cavity. When drilling holes in a spacious rock wall, the first mounting base 4 can be installed in the second clamping cavity. Thus, the propulsion device 100 of the impact drill can be used to drill holes in the top or bottom plate and rock wall of the tunnel, thereby improving the applicability of the propulsion device 100 of the impact drill.

[0048] In some embodiments, the rotating assembly 3 further includes a connecting plate 38, which is connected to the first clamping plate 36 and the second clamping plate 37 respectively. Specifically, as Figure 6 As shown, the connecting plate 38 is a vertical plate that extends in the left and right direction. The connecting plate 38 is fixed to the end faces of the second section 362 and the fourth section 372, thereby forming the first clamping plate 36 and the second clamping plate 37 into a whole through the connecting plate 38. The connecting plate 38 also improves the strength and service life of the first clamping plate 36 and the second clamping plate 37 and prevents the first clamping plate 36 and the second clamping plate 37 from deforming.

[0049] In some embodiments, the support assembly 2 includes a first support portion 21, a second support portion 22, and a third support portion 23 connected in sequence. The first support portion 21 is disposed on the transport vehicle 1 and is rotatable relative to the transport vehicle 1 about its width direction. The first support portion 21 and the second support portion 22 are connected, and the extending directions of the first support portion 21 and the second support portion 22 intersect at an angle. The third support portion 23 is disposed at the free end of the second support portion 22 and is rotatable relative to the second support portion 22 about its width direction. A rotating assembly 3 is disposed at the free end of the third support portion 23. Specifically, as shown... Figure 1-2 As shown, the first support part 21, the second support part 22, and the third support part 23 are all support frames. The first support part 21 extends in the vertical direction, and the lower end of the first support part 21 is rotatably mounted on the transport vehicle 1 in the front-back direction. The second support part 22 extends from right to left and is inclined upward. The upper end of the first support part 21 is fixedly connected to the lower right end of the second support part 22 (in other words, the first support part 21 and the second support part 22 are roughly L-shaped), so that the first support part 21 drives the second support part 22 to rotate. The upper left section of the second support part 22 is rotatably connected to the right end of the third support part 23. The third support part 23 can rotate in the front-back direction in the upper left section of the second support part 22. The rotating component 3 is located at the left end of the third support part 23. Thus, the movement of the first support part 21, the second support part 22, and the third support part 23 drives the rotating component 3 to move in the vertical direction, thereby driving the drilling component 5 to move in the vertical direction to adjust the drilling position.

[0050] In some embodiments, the support component 2 further includes a first drive element 24, a second drive element 25, and a third drive element 26.

[0051] The base of the first driving member 24 is rotatably mounted on the transport vehicle 1, and the driving end of the first driving member 24 is rotatably mounted at the connection between the first support portion 21 and the second support portion 22, so that the first driving member 24 drives the first support portion 21 to rotate. Specifically, as shown... Figure 1-2 As shown, the first driving member 24 is an electric telescopic rod or a hydraulic rod. The driving end of the first driving member 24 and the base of the first driving member 24 are respectively located at the upper and lower ends of the first driving member 24. The first driving member 24 extends in the vertical direction and is located on the left side of the first support part 21 and the lower side of the second support part 22. The base of the first driving member 24 is hinged to the transport vehicle 1. The driving end of the first driving member 24 is hinged to the connection between the first support part 21 and the second support part 22, so that the first driving member 24 can perform telescopic movement to drive the first support part 21 to rotate in the front-back direction.

[0052] The base of the second driving member 25 is rotatably disposed at one end of the second support portion 22 adjacent to the first support portion 21, and the driving end of the second driving member 25 is rotatably connected to the third support portion 23 so that the second driving member 25 drives the third support portion 23 to rotate. Specifically, as shown... Figure 1-2 As shown, the second driving member 25 is an electric telescopic rod or a hydraulic rod. The driving end of the second driving member 25 and the base of the second driving member 25 are respectively located at the left and right ends of the second driving member 25. The second driving member 25 extends in the left and right direction and is located on the upper side of the second support part 22. The base of the second driving part is hinged to the right end of the second support part 22, and the driving end of the second driving part is hinged to the right end of the third support part 23. Thus, the telescopic movement of the second driving part drives the third support part 23 to rotate around the front and back direction at the left end of the second support part 22.

[0053] The base of the third driving member 26 is rotatably disposed at one end of the third support portion 23 adjacent to the second support portion 22. The driving end of the third driving member 26 is rotatably connected to the rotating assembly 3, so that the third driving member 26 drives the rotating assembly 3 to rotate about the width direction of the driving vehicle. Specifically, as Figure 1-2 As shown, the third driving member 26 is an electric telescopic rod or a hydraulic rod. The driving end and the base of the third driving member 26 are respectively located at the left and right ends of the third driving member 26. The third driving member 26 extends in the left and right direction and is located on the upper side of the third support part 23. The base of the third driving member 26 is hinged to the right end of the third support part 23, and the driving end of the third driving member 26 is hinged to the second mounting seat 31. Thus, the second mounting seat 31 can be rotated in the front and back direction by the telescopic movement of the third driving member 26. Therefore, when it is necessary to adjust the drilling height, the first driving member 24 and the second driving member 25 can be activated to telescopically move and adjust the height of the drilling assembly 5. The third driving member 26 is activated to adjust the second mounting seat 31 so that the mounting seat is always in a horizontal state, ensuring the quality of drilling.

[0054] In some embodiments, such as Figure 1-2 As shown, the support component 2 also includes a first connecting part 27 and a second connecting part 28.

[0055] The first connecting part 27 is fixed to the right end of the third support part 23 and located on the upper side of the third support part 23. The first connecting part 27 is located between the base of the third drive member 26 and the drive end of the second drive member 25, and the left and right sides of the first connecting part 27 are respectively hinged to the base of the third drive member 26 and the drive end of the second drive member 25. Thus, the first connecting part 27 provides a mounting base for the base of the third drive member 26 and the drive end of the second drive member 25.

[0056] The second connecting part 28 includes an arc plate 281 and a connecting rod 282. One end of the arc plate is hinged to the left end of the third driving part, and the arc plate is bent towards the left end of the third driving part. One end of the connecting rod 282 is hinged to the other end of the arc plate, and the other end of the connecting rod 282 is hinged to the first vertical plate 311 and the second vertical plate 312 of the second mounting base 31. The driving end of the third driving member 26 is located at the hinge between the arc plate 281 and the connecting rod 282. Thus, the third driving member 26 drives the second mounting base 31 to rotate through the second connecting part 28.

[0057] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the drilling assembly 5 includes a third mounting base 51, a fourth drive unit 52, and an impact drill 53.

[0058] The third mounting base 51 is disposed on the first mounting base 4 and is movable along the length direction of the first mounting base 4. The fourth driving member 52 is connected to the third mounting base 51 so that the fourth driving member 52 drives the third mounting base 51 to move along the length direction of the first mounting base 4. The third mounting base 51 is disposed at the left end of the first mounting base 4, and the fourth driving member 52 is disposed on the first mounting base 4 and the driving end of the fourth driving member 52 is connected to the third mounting base 51, so that the fourth driving member 52 can drive the third mounting base 51 to move along the front-back direction of the first mounting base 4.

[0059] The impact drill 53 is mounted on the third mounting base 51 so that the third mounting base 51 can drive the impact drill 53 to move on the first mounting base 4. Thus, the impact drill 53 can be mounted on the third mounting base 51 by fasteners, and the drill bit of the impact drill 53 extends in the front-to-back direction. The impact drill 53 can drive the drill bit to rotate on the third mounting base 51, and the third mounting base 51 drives the impact drill 53 to move in the front-to-back direction, thereby drilling a hole through the cooperation of the impact drill 53 and the third mounting base 51.

[0060] In some embodiments, one of the first mounting base 4 and the third mounting base 51 is provided with a sliding groove, and the other of the first mounting base 4 and the third mounting base 51 is provided with a slider 41 that slides in cooperation with the sliding groove, and the sliding groove and the sliding groove slide in cooperation. Specifically, as Figure 7 As shown, the slide groove and slider 41 (slider 41 can be a dovetail guide) can be set according to the actual situation. For example, the left side of the first mounting base 4 is provided with a slide groove extending in the front-back direction, and the right side of the third mounting base 51 is provided with a slider 41 that slides in cooperation with the slide groove. Alternatively, the left side of the first mounting base 4 is provided with a slider 41 extending in the front-back direction, and the right side of the third mounting base 51 is provided with a slide groove that slides in cooperation with the slide groove. Thus, through the cooperation of the slide groove and slider 41, the third mounting base 51 moves in a preset direction, making the propulsion device 100 of the impact drill more reasonably set.

[0061] In some embodiments, the fourth driving member 52 includes a lead screw 521 and a second motor 522. The lead screw 521 is rotatably mounted on the first mounting base 4 and extends along the length direction of the first mounting base 4. The third mounting base 51 has a threaded hole that passes through the third mounting base 51 along the length direction of the first mounting base 4. The threaded hole engages with the lead screw 521 to allow the lead screw 521 to rotate. The motor is mounted on the first mounting base 4 and connected to the lead screw 521 so that the motor drives the lead screw 521 to rotate, thereby driving the third mounting base 51 to move along the length direction of the first mounting base 4. Specifically, as shown... Figure 1 , Figure 2 and Figure 7 As shown, the lead screw 521 extends in the front-to-back direction and is rotatably mounted on the left side of the first mounting base 4 via a rubber sealed bearing. The third mounting base 51 is provided with a threaded hole that cooperates with the lead screw 521 and passes through the third mounting base 51 in the front-to-back direction. The second motor 522 is located on the front side of the first mounting base 4 and is connected to the lead screw 521, thereby driving the third mounting base 51 to move by rotating the lead screw 521, and then driving the impact drill 53 to perform feed motion.

[0062] The working principle of the impact drill propulsion device 100 in this embodiment of the invention is as follows: The first drive member 24, the second drive member 25, the third drive member 26, and the first motor 32 are activated, causing the various structural components (first support 21, second support 22, third support 23, and second mounting base 31) to move in coordination, pushing the drill rod of the impact drill 53 to the designated drilling position. The first mounting base 4 is located in the first clamping sub-cavity. The impact drill 53 is activated, causing the drill rod of the impact drill 53 to rotate. The second motor 522 is activated to drive the lead screw 521 to rotate, driving the third mounting base 51 to advance in a direction away from the second motor 522, drilling a hole of a specified depth. When drilling on the roof or floor of a tunnel, the first motor 32 is rotated, sequentially driving the turntable 33 and the first mounting base 4 to rotate, adjusting the drill rod to the specified angle, and drilling can then be performed. When drilling on a spacious rock wall, the first mounting base 4 is installed in the second clamping sub-cavity, and the drilling assembly 5 is rotated 90 degrees, allowing holes to be drilled on the rock wall or wall surface.

[0063] The beneficial effects of the impact drill propulsion device 100 of this embodiment of the invention are as follows:

[0064] 1) The base is stable and the movement is quick. The present invention uses the transport vehicle 1 and the support component 2 as the support base for the propulsion of the impact drill 53. Its supporting force far exceeds the reaction force of the impact drill 53 during the propulsion process. The risk of the transport vehicle 1 and the support component 2 tipping over is relatively low, and the change of working position is convenient and quick.

[0065] 2) The impact drill 53 is easy to adjust in direction; the first motor 32 is connected to the drilling assembly 5 through the turntable 33. The rotation of the first motor 32 can drive the first mounting base 4 and the impact drill 53 to rotate arbitrarily within a 360-degree range. In this way, when drilling in the tunnel, the first motor 32 can rotate the impact drill 53 to the upward drilling position in the direction of the roof, the downward drilling position in the direction of the bottom, and the horizontal or inclined drilling position on both sides of the tunnel. When drilling on a spacious rock wall or wall, the first mounting base 4 can be set in the second clamping cavity to rotate the drilling direction by 90 degrees and point the impact drill 53 in front of the excavator for drilling operations, which is convenient for adjusting the direction of the impact drill 53.

[0066] 3) High drilling efficiency; the impact drill 53 is driven to reciprocate through the cooperation of the lead screw 521, the third mounting base 51, and the second motor 522 to drill holes in concrete, brick walls, or rock walls. This feeding mechanism provides a large thrust to the impact drill 53 and has a stable feed speed. Furthermore, the feed speed of the impact drill 53 can be changed by altering the rotation speed of the second motor 522, allowing the speed of the impact drill 53 to be set arbitrarily, thereby improving the drilling efficiency.

[0067] 4) Reduce the difficulty of drilling at higher positions; construction workers do not need to climb onto high working platforms such as A-frame ladders or scaffolding to drill holes with hand-held impact drills, which reduces the difficulty of drilling at higher positions.

[0068] 5) Reduce the workload of operators; when drilling in hard rock walls or concrete, operators need to press the impact drill 53 for a long time to drill a hole of a specified depth, which consumes a lot of physical energy. Using this invention to drill in hard rock walls can effectively reduce the workload of operators.
