[0031] Example

[0032] See also Figure 1 and Figure 2 The present embodiment provides an anchor drilling vehicle 100 for performing anchor construction operations in coal mine tunnels. The anchor drilling vehicle 100 can be used not only for top anchor construction operations but also for auxiliary anchor construction operations.

[0033] The anchor drilling vehicle 100 provided in this embodiment includes a traveling mechanism 110, a drilling mechanism 130, a telescopic arm 150, a temporary support mechanism 170 and a lifting platform 190. The lifting platform 190 is movably arranged on the traveling mechanism 110 and can move up and down relative to the traveling mechanism 110. One end of the telescopic arm 150 is hinged to the front end of the lifting platform 190 and can rotate relative to the lifting platform 190. The other end of the telescopic arm 150 is connected to the drilling mechanism 130, and is used to drive the drilling mechanism 130 to approach or move away from the lifting platform 190. The temporary support mechanism 170 is arranged on the upper part of the lifting platform 190 and extends upward.

[0034] It should be noted that the drilling mechanism 130 is used to implement bolting operations. The bolting drilling vehicle 100 provided in this embodiment is a double-arm hydraulic bolting cable drilling vehicle, wherein there are two drilling mechanisms 130, which are respectively arranged on both sides of the front end of the lifting platform 190, so as to be conveniently extended toward the left front and the right front, so that bolting operations can be performed from both sides. Of course, the number of drilling mechanisms 130 is not limited here, and under the premise of ensuring balance, the number of drilling mechanisms 130 can also be three or four.

[0035] In this embodiment, the traveling mechanism 110 is provided with a plurality of lifting driving members 111, which are transmission-connected to the lifting platform 190 and are used to lift the lifting platform 190. Specifically, the lifting driving members 111 are main lifting cylinders, and there are four main lifting cylinders. The four lifting driving members 111 are respectively arranged around the lifting platform 190, and the lifting of the lifting platform 190 is realized by the synchronous action of the four main lifting cylinders.

[0036] In this embodiment, a connecting rod mechanism 113 is also provided on the walking mechanism 110. The connecting rod mechanism 113 is connected upward to the bottom of the lifting platform 190, and the connecting rod mechanism 113 is foldable. It can be folded or stretched as the lifting platform 190 moves up and down, and is used to cooperate with the main lifting cylinder to realize the lifting of the lifting platform 190.

[0037] It should be noted that the rear end of the traveling mechanism 110 is also provided with a hydraulic system 115 and an electric control system 117. The hydraulic system 115 includes an oil tank, a hydraulic oil pump, a motor, a hydraulic oil cylinder, a balance valve, a joint, a hydraulic pipeline, a cooler, and a control valve located on the hydraulic pipeline. The hydraulic pipeline includes a pipeline connecting the oil tank outlet with the hydraulic oil pump and connecting the hydraulic oil pump outlet with the traveling mechanism 110, the bolter 135, the temporary support mechanism 170, the left drilling part, the right drilling machine part, etc. The bolt drilling vehicle 100 obtains power from the hydraulic oil pump, and then transmits the power to each actuator through the hydraulic pipeline, and the control valve corresponding to each actuator cooperates to complete the actions of walking, drilling, temporary support, etc. The electrical system includes a mining explosion-proof electric meter, a light rubber-sheathed soft cable for coal mines, an explosion-proof junction box, a reversing alarm, a mining voice and light signal device, a mining explosion-proof and intrinsically safe vacuum electromagnetic starter, and a mining lighting lamp, etc., to provide electrical energy for each actuator of the bolt drilling vehicle 100. Here, the hydraulic system 115 and the electronic control system 117 are both prior art.

[0038] In this embodiment, the traveling mechanism 110 is a crawler-type vehicle body and has an installation platform. The hydraulic system 115 and the electric control system 117 are arranged at the rear of the installation platform, and the lifting platform 190 is arranged at the front of the installation platform.

[0039] See also Figure 3 The temporary support mechanism 170 includes a support frame 171, a support cylinder 173, a first support driving member 175 and a second support driving member 177. One end of the support cylinder 173 is connected to the lifting platform 190, and the support frame 171 is connected to the other end of the support cylinder 173. The two ends of the support cylinder 173 are rotatably connected to the lifting platform 190 and the support frame 171 respectively. One end of the first support driving member 175 is connected to the lower part of the support cylinder 173, and the other end of the first support driving member 175 is connected to the support frame 171, which is used to drive the support frame 171 to rotate relative to the support cylinder 173. One end of the second support driving member 177 is connected to the lifting platform 190, and the other end is connected to the support cylinder 173, which is used to drive the support cylinder 173 to rotate relative to the lifting platform 190.

[0040] It should be noted that the first support driving member 175 and the second support driving member 177 are support cylinders, and the lifting and folding of the support frame body 171 are achieved through the support cylinders.

[0041] In this embodiment, there are two support cylinders 173, first support drive member 175 and second support drive member 177. The two support cylinders 173 are respectively connected to the two ends of the lifting platform 190. The support frame 171 is arranged on the top of the two support cylinders 173, and the support cylinders 173 and the lifting platform 190 are both rotatably connected, so that the temporary support mechanism 170 can be retracted and folded above the lifting platform 190 in the non-working state, and unfolded and raised by the action of the oil cylinder when working. By setting up two support cylinders 173, the overall rigidity of the temporary support mechanism 170 is good, and the support area is larger, so the safety of the support operation can be significantly improved. In addition, the temporary support mechanism 170 temporarily supports the top plate of the tunnel, which can improve the stability and safety of the whole vehicle during the support operation.

[0042] See also Figure 4 and Figure 5 The telescopic arm 150 includes a telescopic outer cylinder 151, a telescopic inner cylinder 153 and a telescopic driving member 155. The telescopic outer cylinder 151 is hinged at the front end of the lifting platform 190. One end of the telescopic inner cylinder 153 slides into the telescopic outer cylinder 151. The other end of the telescopic inner cylinder 153 is movably connected to the drilling mechanism 130. The telescopic driving member 155 is arranged in the telescopic outer cylinder 151 and is transmission-connected to the telescopic inner cylinder 153, so as to drive the telescopic inner cylinder 153 to slide along the extension direction of the telescopic outer cylinder 151.

[0043] Specifically, the telescopic drive member 155 is a telescopic oil cylinder, the cylinder body of the oil cylinder is connected to the inner wall of the telescopic outer cylinder 151, and the piston rod of the oil cylinder is connected to the telescopic inner cylinder 153, thereby driving the telescopic inner cylinder 153 to slide in the telescopic outer cylinder 151, and then driving the drilling mechanism 130 to approach or move away from the lifting platform 190. The telescopic drive member 155 drives the telescopic inner cylinder 153 to achieve a telescopic action, which is used to compensate for the front and rear changes in the center position caused by the left and right swings of the drilling mechanism 130, ensuring that each support anchor is in the same plane, and facilitating the anchor support operation.

[0044] In this embodiment, a swing drive member 157 is further provided on one side of the telescopic outer cylinder 151, and the swing drive member 157 is connected to the lifting platform 190, and is used to drive the telescopic outer cylinder 151 to rotate relative to the lifting platform 190. Specifically, a swing lug is provided on one side of the telescopic outer cylinder 151, and the swing lug is connected to one end of the swing drive member 157, and the other end of the swing drive member 157 is connected to the lifting platform 190. Here, the swing drive member 157 is a swing oil cylinder, and the movement of the telescopic outer cylinder 151 is controlled by the swing lug. The cylinder body of the swing oil cylinder is rotatably connected to the lifting platform 190, and the piston rod is rotatably connected to the swing lug, thereby achieving the purpose of driving the telescopic outer cylinder 151 to rotate relative to the lifting platform 190.

[0045] In this embodiment, the end of the telescopic outer cylinder 151 is cylindrical, and a rotating shaft is provided at the front end of the lifting platform 190. The end of the telescopic outer cylinder 151 is rotatably connected to the rotating shaft and is driven by a swing cylinder to realize rotation.

[0046] In this embodiment, a first lifting drive member 159 is provided at one end of the telescopic inner cylinder 153 away from the telescopic outer cylinder 151, and the first lifting drive member 159 is in transmission connection with the drilling mechanism 130, and is used to drive the drilling mechanism 130 to move up and down relative to the telescopic inner cylinder 153. Specifically, a slide groove is provided at one end of the telescopic inner cylinder 153 away from the telescopic outer cylinder 151, and the slide groove is arranged in the vertical direction. A slider is provided on the drilling mechanism 130, and the slider is slidably arranged in the slide groove and can move along the slide groove. The first lifting drive member 159 is a lifting cylinder, and the cylinder body of the cylinder is arranged on the telescopic inner cylinder 153. The piston rod of the cylinder is connected to the drilling mechanism 130, and is used to drive the drilling mechanism 130 to move up and down along the slide groove.

[0047] The drilling mechanism 130 includes a lifting frame 131, a standing pedal 133 and an anchor machine 135. The lifting frame 131 is movably connected to an end of the telescopic arm 150 away from the lifting platform 190. The standing pedal 133 is rotatably set at the bottom of the lifting frame 131. The anchor machine 135 is set on one side of the lifting frame 131 and can move up and down relative to the lifting frame 131.

[0048] In this embodiment, a folding drive component is further provided between the standing pedal 133 and the lifting frame 131. Specifically, the folding drive component is a folding cylinder, and both ends of the folding cylinder are respectively connected to the lifting frame 131 and the standing pedal 133, so as to fold the standing pedal 133 on the lifting frame 131 or unfold it.

[0049] In this embodiment, the lifting frame 131 is further provided with a second lifting drive 137, which is in transmission connection with the anchor bolter 135, and is used to drive the anchor bolter 135 to move up and down relative to the lifting frame 131. Specifically, the second lifting drive 137 is a lifting cylinder and is arranged inside the lifting frame 131, and a transmission chain is also arranged inside the lifting frame 131, and the transmission chain is respectively connected to the lifting cylinder and the anchor bolter 135, so that the lifting cylinder is in transmission connection with the anchor bolter 135 through the transmission chain.

[0050] It should be noted that in the present embodiment, there are two transmission chains, which are arranged relative to each other. The second lifting drive member 137 is provided with a sprocket, which drives the transmission chain to move. When the second lifting drive member 137 moves one unit length, the anchor bolt machine 135 moves two unit lengths, and can play a lifting role through the two transmission sprockets.

[0051] Of course, in other preferred embodiments of the present invention, the second lifting drive member 137 is directly connected to the anchor bolt machine 135, and the anchor bolt machine 135 is directly driven up and down by the second lifting drive member 137. The specific connection method is not described in detail here.

[0052] In this embodiment, the bolter 135 includes a bolter body 1351, a lifting plate 1353 and a swing driving member 1355. The lifting plate 1353 is arranged at the bottom of the bolter body 1351. The lifting plate 1353 is provided with a swing driving member 1355. The swing driving member 1355 is connected to the bolter body 1351 in a transmission connection and is used to drive the bolter body 1351 to rotate relative to the lifting plate 1353. The lifting plate 1353 is connected to the second lifting driving member 137 in a transmission connection. It should be noted that the specific structure of the bolter body 1351 is consistent with the existing bolting device, and no further description is given here.

[0053] In this embodiment, the swing drive member 1355 includes two swing cylinders arranged perpendicular to each other. The two swing cylinders can realize the left and right swing and the front and back swing of the anchor bolt machine body 1351, so that the anchor bolt machine body 1351 can be accurately moved to a predetermined position.

[0054] It should be noted that the anchor drilling rig provided in this embodiment is powered by the hydraulic system 115, and the driving parts mentioned are all hydraulic cylinders. Of course, it is not limited to this. The driving parts in this embodiment can also be other forms of driving structures such as electric push rods or cylinders, which are not specifically limited here.

[0055] It is worth noting that in the present embodiment, the lifting drive member 111 drives the lifting platform 190 to move up and down, realizing the first-level lifting action of the anchor machine 135, and the first lifting drive member 159 between the telescopic inner tube 153 and the lifting frame 131 drives the lifting frame 131 to move up and down, realizing the second-level lifting action of the anchor machine 135. The second lifting drive member 137 on the lifting frame 131 drives the anchor machine 135 to move up and down, realizing the third-level lifting action of the anchor machine 135. The three-level lifting action cooperates with the construction operation of the anchor machine 135 on the side wall of the tunnel. Since the three-level lifting action is a linear motion or a nearly linear motion, the operator only needs to control one action in the height direction, and does not need to make additional adjustment actions to realize the construction operation of the entire side wall, which significantly improves the efficiency of the anchor support operation.

[0056] In addition, the operator moves synchronously with the lifting frame 131 on the standing pedal 133, and there is no need to adjust the position of the standing pedal 133 separately to adapt to the position of the anchor machine 135; there will be no problem that when the tunnel is too high, although the top anchor operation can be carried out, the anchor agent cannot be installed; there will be no problem that the operator moves a large range between the anchor machine 135 and the control handle; because the position of the operator and the anchor machine 135 is synchronized, the efficiency of the top anchor support operation is significantly improved.

[0057] In actual work, when the anchor drilling vehicle 100 reaches the working position, it first performs the top anchor support operation, and then performs the side anchor support operation. When performing the top anchor support operation, the operator opens the standing pedal 133 and stands on the standing pedal 133 to work, and after adjusting the height of the lifting platform 190 according to the height of the tunnel, unfolds and raises the temporary support mechanism 170 to temporarily support the tunnel roof. The temporary support of the tunnel roof can improve the safety during the support operation and the stability of the vehicle. One of the drilling mechanisms 130 starts with the anchor in the middle of the tunnel, and then completes the operation of the anchor near the side wall; while the top anchor operation sequence of the other drilling mechanism 130 is the opposite. The drilling operation position of the anchor bolt machine body 1351 is adjusted by controlling the two swing cylinders of the anchor bolt machine body 1351 and the swing cylinder of the drilling mechanism 130. When performing top anchor bolt operations close to the side wall, the telescopic inner cylinder 153 needs to be extended to compensate for the position of the drilling anchor bolt machine 135.

[0058] After the top anchor support operation is completed, the auxiliary anchor support construction operation is carried out. The auxiliary anchor support is carried out from high to low positions in sequence. First, the two swing cylinders are operated to adjust the anchor machine body 1351 to the auxiliary anchor support operation state; the transmission chain cooperates with the lifting cylinder to raise the anchor machine body 1351 to the highest position, and after adjusting the lifting frame 131 to the appropriate height, the uppermost auxiliary anchor is operated, and the corresponding cylinders that adjust the three-level lifting action are used to perform the anchor drilling operation in sequence.

[0059] In summary, the present embodiment provides an anchor drilling vehicle 100. When performing anchor operations, the lifting platform 190 can move up and down relative to the walking mechanism 110, so that the drilling mechanism 130 can move in the up and down directions. The telescopic arm 150 can rotate relative to the lifting platform 190, so as to drive the drilling mechanism 130 to swing and realize the movement in the left and right directions. The telescopic arm 150 can approach or move away from the lifting platform 190, so as to drive the drilling mechanism 130 to move forward and backward, and realize the three-dimensional movement of the drilling mechanism 130. It is used in tunnels under various working conditions, and at the same time, the operation of auxiliary anchors and top anchors can be realized through the drilling mechanism 130. At the same time, due to the support function of the temporary support mechanism 170, support can be obtained when performing top anchor operations, ensuring the safety of top anchor operations. In addition, the present invention has a compact structure, reasonable layout, convenient operation, can realize the anchor and cable support construction of the entire section of the tunnel, has a high safety factor, is suitable for working in harsh environments, and is an ideal underground mining safety support equipment.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
