Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically a tunnel borehole correction device. Background Technology

[0002] In the drilling and blasting process of traditional underground engineering construction, drilling operations largely rely on manual labor. Workers need to hold pneumatic drills and rely on experience to locate and drill holes on the working face. This method not only consumes a lot of manpower and time, but is also affected by human factors. It is difficult to guarantee the accuracy of the drilling position, angle, and depth. The low positioning accuracy of the drilling can easily lead to drilling deviations, affecting the blasting effect and project quality. Utility Model Content

[0003] The purpose of this utility model is to provide a tunnel drilling correction device to solve the problem mentioned in the background art that the traditional handheld pneumatic drill has low drilling positioning accuracy and is prone to drilling deviation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tunnel drilling correction device, comprising a support plate, a rotating plate movably connected inside the support plate, a first connector fixedly connected to one side of the rotating plate, a second connector fixedly connected to the other side of the rotating plate, an insert rod penetrating through the surface of the support plate, a hammer plate fixedly connected to the surface of the insert rod, an adjustment groove formed on the surface of the insert rod, an adjustment frame slidably connected inside the adjustment groove, a threaded sleeve connected to the surface of the adjustment frame, a screw connected to the surface of the adjustment frame, a contact plate connected to the adjustment frame via the screw, a connecting screw ring fixedly connected to the surface of the support plate, a pressure block fixedly connected to the surface of the connecting screw ring, and an adjustment element threadedly sleeved onto the outer surface of the connecting screw ring.

[0005] Preferably, a circular groove is formed in the middle of the support plate, and an annular groove is formed on the inner side of the circular groove. The rotating plate is in the shape of a disc, and a circular ring is fixedly connected to the outer surface of the rotating plate. The rotating plate is rotatably connected to the support plate through the circular ring and the annular groove.

[0006] Preferably, the insertion rods are arranged in four groups that penetrate the surface of the support plate, the end of the insertion rod away from the hammer plate is conical, and the cross-section of the adjustment groove is cross-shaped.

[0007] Preferably, the adjusting frame is in the shape of a cross, the screw sleeve is connected to the opposite ends of the adjusting frame, and the contact plate is connected to the adjacent ends of the adjusting frame and the screw sleeve by a screw.

[0008] Preferably, the contact plate is rotatably connected to the adjusting frame via a screw, and a nut is attached to the surface of the screw. The contact plate abuts against the adjusting frame via the nut and the screw.

[0009] Preferably, a rubber block is fixedly connected to the inner surface of the pressure block, and the adjusting member consists of two parts. One part of the adjusting member is hexagonal in shape and is threadedly connected to the connecting screw ring, and the other part of the adjusting member is cylindrical in shape. The adjusting member abuts against the outer surface of the pressure block through the connecting screw ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The connection between the support plate and the rotating plate, along with the connection between the first and second connecting heads, enables the connection of the drill rod and the drill bit. The connection between the hammer plate and the insertion rod, combined with the use of a spirit level, allows the insertion rod to be inserted into the working face, ensuring the horizontal state of the support plate during use. The connection between the rotating plate and the first connecting head enables the horizontal rotation of the drill rod, ensuring the borehole is horizontal and without deviation. Furthermore, the connection between the adjusting groove and the adjusting frame, through the action of the contact plate, increases the contact area with the working face, improving the stable support performance of the insertion rod on the support plate during insertion.

[0012] 2. By connecting the connecting screw ring and the pressure block, and with the pressure block and the adjusting component connected, the abutting contact between the adjusting component and the pressure block achieves the supporting and limiting effect on the position of the insertion rod on the support plate. This prevents the position of the support plate on the insertion rod from changing during the insertion operation, which would affect the observation of the level of the support plate and thus cause drilling deviation. The abutting contact between the pressure block and the insertion rod fixes the connection position between the insertion rod and the support plate. The support plate moves with the position of the insertion rod, improving the accuracy of the level control of the support plate. Attached Figure Description

[0020] Please see Figure 1-6 One embodiment provided by this utility model:

[0021] A tunnel drilling correction device includes a support plate 1, a rotating plate 2 movably connected inside the support plate 1, a first connector 21 fixedly connected to one side of the rotating plate 2, a second connector 22 fixedly connected to the other side of the rotating plate 2, an insert rod 31 penetrating through the surface of the support plate 1, a hammer plate 3 fixedly connected to the surface of the insert rod 31, an adjustment groove 4 formed on the surface of the insert rod 31, an adjustment frame 5 slidably connected inside the adjustment groove 4, a threaded sleeve 51 connected to the surface of the adjustment frame 5, a screw 52 connected to the surface of the adjustment frame 5, a contact plate 53 connected to the adjustment frame 5 via the screw 52, ​​a connecting ring 6 fixedly connected to the surface of the support plate 1, a pressure block 61 fixedly connected to the surface of the connecting ring 6, and an adjustment element 62 threadedly fitted onto the outer surface of the connecting ring 6. Through the connection between the support plate 1 and the rotating plate 2, and under the action of the first connector 21 and the second connector 22, the connection support and rotation control of the drill rod are achieved. Through the connection between the insert rod 31 and the support plate 1, the support plate 1 is supported and controlled on the tunnel face.

[0022] Furthermore, a circular groove is provided in the middle of the support plate 1, and an annular groove is provided on the inner side of the circular groove. The rotating plate 2 is in the shape of a disc, and a circular ring is fixedly connected to the outer surface of the rotating plate 2. The rotating plate 2 is rotatably connected to the support plate 1 through the circular ring and the annular groove. Through the connection between the rotating plate 2 and the support plate 1, a rotating bead is provided on the inner wall of the circular groove on the support plate 1. The rotating bead and the outer surface of the rotating plate 2 are abutted and rotatably connected, which improves the stability of the rotating plate 2 on the support plate 1.

[0023] Furthermore, the insertion rods 31 are arranged in four groups that penetrate the surface of the support plate 1. The end of the insertion rod 31 away from the hammer plate 3 is conical in shape, and the cross section of the adjustment groove 4 is cross-shaped. Through the connection between the hammer plate 3 and the insertion rods 31, the support position and angle of the support plate 1 can be adjusted by inserting the insertion rods 31 into the working face.

[0024] Furthermore, the adjusting frame 5 is in the shape of a cross, and the screw sleeve 51 is connected to the opposite ends of the adjusting frame 5. The contact plate 53 is connected to the adjacent ends of the adjusting frame 5 and the screw sleeve 51 by the screw 52. Through the connection of the adjusting groove 4 and the adjusting frame 5, the position of the adjusting frame 5 on the insertion rod 31 can be adjusted under the action of the adjusting groove 4. Under the connection of the screw sleeve 51 and the adjusting frame 5, the supporting control effect of the position of the adjusting frame 5 on the insertion rod 31 is realized.

[0025] Furthermore, the contact plate 53 is rotatably connected to the adjusting frame 5 via the screw 52. A nut is attached to the surface of the screw 52. The contact plate 53 abuts against the adjusting frame 5 via the nut and the screw 52. Through the connection between the adjusting frame 5 and the screw 52, ​​the connection angle of the contact plate 53 on the adjusting frame 5 is controlled by the action of the screw 52 and the nut. Through the action of the contact plate 53, its contact area is increased, thereby improving the support stability of the insertion rod 31 on the working face.

[0026] Furthermore, a rubber block is fixedly connected to the inner surface of the pressure block 61. The adjusting component 62 consists of two parts: one part is hexagonal and threadedly connected to the connecting screw ring 6, and the other part is cylindrical. The adjusting component 62 abuts against the outer surface of the pressure block 61 through the connecting screw ring 6. Under the connection of the connecting screw ring 6 and the pressure block 61, the pressure block 61 presses against the insertion rod 31 through the abutting contact between the adjusting component 62 and the outer surface of the pressure block 61. This achieves the supporting effect of the insertion rod 31 at the connection position on the support plate 1, so that the support plate 1 and the insertion rod 31 move synchronously. This prevents the position of the support plate 1 on the insertion rod 31 from changing when the insertion rod 31 is in contact with the working face, which would affect the adjustment of the level of the support plate 1 and cause drilling deviation.

[0027] Working principle: During drilling operations at the tunnel face, a tool is used to insert the insertion rod 31 into the face. Using a spirit level, the levelness of the support plate 1 is observed. Once adjusted, the screw sleeve 51 is rotated, causing the adjusting frame 5 to slide within the adjusting groove 4. The nut on the screw rod 52 is rotated, causing the contact plate 53 to unfold, increasing the contact area. After the contact plate 53 slides to the corresponding position, the screw sleeve 51 is rotated in the opposite direction to complete the fixed support of the adjusting frame 5 within the adjusting groove 4. The function of the first connector 21... The drill bit can be connected to the second connector 22, which in turn connects the drill rod. After the support plate 1 is installed, the adjusting component 62 is rotated to separate the adjusting component 62 from the pressure block 61. At this time, the pressure block 61 and the insertion rod 31 are separated. The drilling machine is then turned on, causing the drill bit to drive the rotating plate 2 to rotate. The second connector 22 drives the drill rod to rotate, completing the drilling operation on the working face. With the sliding connection between the support plate 1 and the insertion rod 31, the limiting and guiding effect is achieved, avoiding deviation in drilling and thus achieving the correction effect.
