Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to an anchor drilling machine and an anchor digging machine. Background Art

[0002] At present, the support frame of the anchor drilling rig is used to support the clamp and guide the movement of the clamp. The anchor drilling box is carried on the extension frame, which is basically driven by a biased single cylinder and guided by a cylindrical guide rail.

[0034] like Figure 1 and Figure 2 As shown, the anchor drilling rig provided by the embodiment of the utility model includes a frame 100, a support assembly 200, an extension assembly 300, an anchor drilling box 400 and a first driving member 500, the support assembly 200 includes a first guide rod 210 and a support plate 220, the first guide rod 210 is slidably connected to the frame 100, and the support plate 220 is arranged at the end of the first guide rod 210; the extension assembly 300 includes a second guide rod 310 and an end plate 320, the second guide rod 310 is axially parallel to the first guide rod 210, the end plate 320 is arranged on the second guide rod 310 close to the end of the support plate 220, and the end plate 320 is slidably connected to the first guide rod 210; the anchor drilling box 400 is arranged on the second guide rod 310; the first driving member 500 is connected to the end plate 320 to drive the end plate 320 to move along the first guide rod 210.

[0035] In the anchor drilling rig of the present utility model embodiment, the frame 100 serves as the main supporting structure of the anchor drilling rig, and is used to provide support for the first guide rod 210 and the second guide rod 310. The first guide rod 210 and the second guide rod 310 are arranged in parallel, and the front end of the first guide rod 210 is connected to the support plate 220, and the front end of the second guide rod 310 is connected to the end plate 320. When the anchor drilling rig is in working state, the first guide rod 210 and the support plate 220 move forward along the axial direction of the first guide rod 210 on the frame 100 until the support plate 220 abuts against the rock wall, and the first driving member 500 drives the end plate 320 to move forward along the axial direction of the first guide rod 210, and the anchor drilling box 400 is arranged on the second guide rod 310, so that when the end plate 320 moves, the anchor drilling box 400 can be driven by the second guide rod 310 to move closer to the support plate 220.

[0036] Since the end plate 320 is slidably connected to the first guide rod 210, the first guide rod 210 guides and stably supports the end plate 320 during the movement of the end plate 320, which is equivalent to stably supporting the movement of the second guide rod 310 and the anchor drill box 400 thereon. Through the sliding connection between the end plate 320 and the first guide rod 210, the anchor drill box 400 is further supported during the movement operation, avoiding the anchor drill box 400 and the extension assembly 300 being in a suspended operation state. The end plate 320 has both a guiding function and a guiding correction function, reducing the eccentric load effect of the first drive member 500 and improving the guiding stability. The end plate 320 at the front end of the extension assembly 300 is extended to the first guide rod 210 of the support assembly 200 to form a guiding support, so as to achieve the effect of using the existing structure for improvement without increasing the additional structural space. The problem of the shaking of the anchor drill box 400 during the operation of the anchor drill and the aggravated eccentric load wear of the first drive member 500 due to the long telescopic stroke distance is solved.

[0037] In this embodiment, the second guide rod 310 may be disposed above the first guide rod 210, and the end plate 320 extends downward to the first guide rod 210 to form a sliding connection with the first guide rod 210. The first driving member 500 may be a telescopic cylinder.

[0038] According to an embodiment provided by the utility model, the anchor drill further includes a second driving member 600, which is disposed on the frame 100 and connected to the support plate 220 to drive the support plate 220 and the first guide rod 210 to move. In this embodiment, the frame 100 supports and fixes the second driving member 600, and the second driving member 600 can directly drive the support plate 220 to move. During the movement of the support plate 220, the first guide rod 210 is driven to slide on the frame 100, providing guidance and support stability for the movement of the support plate 220.

[0039] In this embodiment, when the anchor drilling machine is in working state, the second driving member 600 first drives the support plate 220 to move forward along the axial direction of the first guide rod 210 until the support plate 220 abuts against the rock wall, and the first driving member 500 then drives the end plate 320 to move forward along the axial direction of the first guide rod 210, thereby driving the anchor drilling box 400 to approach the rock wall. When the anchor drilling machine ends working state, the first driving member 500 first drives the end plate 320 to move backward along the axial direction of the first guide rod 210, thereby driving the anchor drilling box 400 away from the rock wall, and the second driving member 600 then drives the support plate 220 to move backward along the axial direction of the first guide rod 210 until the support plate 220 retreats to the standby position. The second driving member 600 can be a telescopic cylinder.

[0040] According to an embodiment provided by the utility model, the extension assembly 300 further includes a third guide rod 330, the third guide rod 330 is slidably connected to the frame body 100, and the third guide rod 330 is connected to the second guide rod 310 through the end plate 320. In this embodiment, the third guide rod 330 and the second guide rod 310 are arranged parallel to each other, and the front end of the third guide rod 330 is also connected to the end plate 320, that is, the second guide rod 310 and the third guide rod 330 of the extension assembly 300 are connected as a whole through the end plate 320, and the third guide rod 330 forms a sliding connection relationship with the frame body 100. In the process of the first driving member 500 driving the end plate 320 to move, the third guide rod 330 can provide guiding stability for the driving of the first driving member 500, and further provide support for the anchor drill box 400, while improving the guiding and deviation correction effect of the end plate 320.

[0041] In this embodiment, the third guide rod 330 is arranged below the second guide rod 310, that is, the second guide rod 310, the third guide rod 330 and the first guide rod 210 are arranged in sequence from top to bottom. The rear end of the third guide rod 330 is connected to the rear end of the second guide rod 310 through a connecting plate, so that the third guide rod 330, the second guide rod 310, the end plate 320 and the connecting plate form an integral structure.

[0042] According to an embodiment provided by the utility model, the support plate 220 is provided with a first side surface and a second side surface opposite to each other, the first side surface is connected to the first guide rod 210, and the second side surface is provided with a tooth 221, and the tooth 221 is suitable for inserting into the rock wall. In this embodiment, the support plate 220 is provided with a tooth 221 on the side abutting against the rock wall, and the tooth 221 is a sawtooth shape distributed in a strip shape. When the support plate 220 abuts against the rock wall, the tooth 221 can be inserted into the rock wall, thereby enhancing the supporting force of the support plate 220 on the rock wall, facilitating the positioning and fixing of the support plate 220 and the first guide rod 210, and further improving the supporting effect of the support assembly 200 on the anchor drill box 400 through the end plate 320 when the anchor drill box 400 is operating.

[0043] In this embodiment, two inserting teeth 221 are disposed on the support plate 220 , and the two inserting teeth 221 are disposed opposite to each other and in parallel in the vertical direction.

[0044] According to an embodiment provided by the utility model, the end plate 320 is provided with a through hole, and the first guide rod 210 is passed through the through hole and connected to the support plate 220. In this embodiment, the end plate 320 extends toward the first guide rod 210, and a through hole is provided on the end plate 320, and the first guide rod 210 passes through the through hole and is connected to the support plate 220. The end plate 320 is slidably connected to the first guide rod 210 through the through hole, which simplifies the structural composition of the connection between the end plate 320 and the first guide rod 210, and saves the space occupied by the structure.

[0045] In other embodiments, the end plate 320 may also form a sliding connection with the first guide rod 210 through other structures, such as a sleeve or a sliding block that matches the shape of the first guide rod 210 .

[0046] According to an embodiment provided by the utility model, the extension assembly 300 includes at least two second guide rods 310, the axial directions of all the second guide rods 310 are parallel to each other in the same horizontal plane, and the third guide rods 330 are arranged one by one with the second guide rods 310. In this embodiment, the extension assembly 300 is provided with two second guide rods 310 and two third guide rods 330, the two second guide rods 310 are arranged in parallel on the horizontal plane, and the third guide rods 330 are also arranged in parallel on the horizontal plane below the second guide rods 310, and the two second guide rods 310 are jointly equipped with the anchor drill box 400, and the two third guide rods 330 are both slidably connected with the frame 100. Multiple second guide rods 310 can make the anchor drill box 400 stable and dispersed and balanced in loading force, and multiple third guide rods 330 can make the movement and guidance of the end plate 320, the second guide rods 310 and the anchor drill box 400 more stable.

[0047] In this embodiment, the two third guide rods 330 are respectively located outside the two second guide rods 310, so as to further improve the stability of the guidance and disperse the supporting force of the extension assembly 300 on the anchor drill box 400.

[0048] According to an embodiment provided by the utility model, the first driving member 500 is disposed on the frame 100, and the first driving member 500 is located on the left or right side of the plurality of second guide rods 310. In this embodiment, a single first driving member 500 is used to drive the end plate 320, and there is no need to consider the synchronization when the plurality of first driving members 500 are driven, so as to avoid the eccentric load on the second guide rod 310 caused by the use of the plurality of first driving members 500. When the anchor drilling machine is in working state, only one telescopic oil cylinder is extended to form a single-side drive on the end plate 320, which can minimize the eccentric load wear.

[0049] In this embodiment, the telescopic cylinder serves as the first driving member 500, the cylinder body is fixed on the frame 100, the piston rod is connected to the end plate 320, and the left and right sides of the second guide rod 310 refer to the two sides perpendicular to the axial direction of the second guide rod 310, and are located in the same horizontal plane as the second guide rod 310 as much as possible.

[0050] According to an embodiment provided by the utility model, the extension assembly 300 includes at least two first guide rods 210, the axial directions of all the first guide rods 210 are parallel to each other in the same horizontal plane, and the second driving member 600 is located on the left or right side of the plurality of first guide rods 210. In this embodiment, the support assembly 200 is provided with two first guide rods 210, the two first guide rods 210 are arranged in parallel on the horizontal plane, the two first guide rods 210 are connected to the support plate 220, and the two first guide rods 210 are slidably connected to the frame 100. The plurality of first guide rods 210 can make the movement and guidance of the support plate 220 more stable, and disperse and balance the support force of the end plate 320.

[0051] In this embodiment, a single second driving member 600 is used to drive the support plate 220. There is no need to consider the synchronization of multiple second driving members 600 when driving, thereby avoiding the off-center load on the first guide rod 210 caused by the use of multiple second driving members 600. When the anchor drilling rig is in working condition, only one telescopic cylinder is extended to form a single-sided drive on the support plate 220, which can minimize the off-center load wear.

[0052] In this embodiment, the telescopic cylinder serves as the second driving member 600, the cylinder body is fixed on the frame 100, the piston rod is connected to the support plate 220, and the left and right sides of the first guide rod 210 refer to the two sides perpendicular to the axial direction of the first guide rod 210, and are located in the same horizontal plane as the first guide rod 210 as much as possible.

[0053] According to an embodiment provided by the utility model, the anchor drilling rig also includes a clamp 700 and a third driving member, the clamp 700 is arranged on the support plate 220, and the clamp 700 is arranged opposite to the anchor drilling box 400; the third driving member is arranged on the frame 100, and the third driving member is connected to the anchor drilling box 400 to drive the anchor drilling box 400 to move along the second guide rod 310.

[0054] In this embodiment, a clamp 700 is disposed on the upper portion of the support plate 220, and the anchor drill box 400 is disposed opposite to the clamp 700. The clamp 700 clamps and fixes the anchor installed on the anchor drill box 400. The third driving member can drive the anchor drill box 400 to move on the second guide rod 310, thereby changing the distance between the anchor drill box 400 and the clamp 700. Since the end plate 320 adds support between the first guide rod 210 and the second guide rod 310, compared with the cantilever operation in which only the first guide rod 210 is connected to the clamp 700, the bending resistance of the clamp 700 can be greatly improved.

[0055] When the anchor drilling rig is in working state, the second driving member 600 first drives the support plate 220 to move forward along the axial direction of the first guide rod 210 until the support plate 220 abuts against the rock wall, and the first driving member 500 then drives the end plate 320 to move forward along the axial direction of the first guide rod 210, thereby driving the anchor drill box 400 to approach the rock wall, and finally the third driving member drives the anchor drill box 400 to move forward along the axial direction of the second guide rod 310, and the anchor moves forward to the set position on the clamp 700. When the anchor drill machine ends its working state, the third driving member can first drive the anchor drill box 400 to move backward along the axial direction of the second guide rod, and the anchor rod retreats on the clamp 700. The first driving member 500 then drives the end plate 320 to move backward along the axial direction of the first guide rod 210, thereby driving the anchor drill box 400 away from the rock wall. Finally, the second driving member 600 drives the support plate 220 to move backward along the axial direction of the first guide rod 210 until the support plate 220 retreats to the standby position. The third driving member can be a telescopic cylinder.
