Description

Technical Field

[0001] This application relates to the technical field of coal mine engineering equipment, and in particular to a hole-peeping device for underground drilling in coal mines. Background Technology

[0002] After drilling a tunnel in a coal mine, the tunnel needs to be cleaned. Then, an endoscope is inserted into the borehole via a push rod to observe the rock strata at different locations and analyze the degree of delamination fracture development.

[0003] Because of the depth of the borehole, the viewing device is typically inserted to the corresponding depth by assembling multiple push rods. After the push rods are connected, the viewing device's cable is usually located on one side of the push rod. During the insertion of the viewing device into the borehole, the cable will come into contact with the borehole wall, causing wear. When pulling the viewing device out, the cable may also become congested inside the borehole, requiring the cable to be pulled downwards, reducing the efficiency of both insertion and removal. Another type of push rod involves wrapping the cable inside after installation. While this reduces the cable's impact, it requires additional cable wrapping during installation, resulting in lower installation efficiency. Utility Model Content

[0004] The purpose of this utility model application is to improve the low installation and propulsion efficiency of existing borehole inspection instruments. This application provides a borehole inspection instrument pushing device for underground drilling in coal mines.

[0005] The technical solution provided in this application for a borehole inspection instrument pushing device for underground coal mine drilling adopts the following:

[0006] A device for pushing an endoscope for drilling in coal mines, comprising:

[0007] The support frame is a tripod with a push-in frame mounted on top.

[0008] The main pole has a viewing device installed at the top. The cable extends from the bottom of the main pole and is wound on a cable drum. It slides vertically to the push frame. The two opposite outer walls at the bottom have slots.

[0009] The sub-rod has a U-shaped cross-section. The slot is also located at the bottom of the sub-rod. The two inner sidewalls at the top of the sub-rod are provided with locking blocks. The locking blocks can be locked in the slot with an interference fit, and the cable can be located inside the sub-rod.

[0010] The clamping wheels are mounted on the push frame. There are two of them, both driven by a motor. The two clamping wheels are located on both sides of the main rod and can clamp the opposite side walls of the main rod or the auxiliary rod. The circumferential outer wall is made of rubber.

[0011] The inner pressure plate is installed on the push frame, located below the clamping wheel, and is rotatably connected to the inner pressure wheel at its end. The inner pressure wheel can press the cable into the auxiliary rod. The inner pressure wheel is made of rubber.

[0012] Optionally, the inner pressure plate is inclined downward and rotatably connected to the push frame. The rotating shaft of the inner pressure plate is equipped with a torsion spring, so that the inner pressure wheel can press the cable against the inner wall of the auxiliary rod.

[0013] Optionally, an anti-detachment layer is fixed to the end of the side wall at the opening of the sub-rod. The anti-detachment layer is made of a soft material that can be elastically deformed. When the cable enters the sub-rod, it will come into contact with the anti-detachment layer.

[0014] Optionally, the anti-detachment layer is an adhesive sponge.

[0015] Optionally, a rubber strip is attached to the inner wall of the side of the auxiliary rod facing its own opening.

[0016] Optionally, the support frame is provided with a placement frame for accommodating multiple auxiliary rods.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By inserting the auxiliary rod into the slot of the main rod, the connection between the main rod and the auxiliary rod can be completed. The auxiliary rod can also be extended in the same way. Then, the endoscope can be easily sent into the borehole through the clamping wheel via the auxiliary rod. At the same time, through the clamping relationship between the inner pressure wheel and the cable, the cable can be automatically pressed into the auxiliary rod, reducing the probability of the cable being squeezed and blocked in the borehole, thereby improving the efficiency of endoscope push rod installation and push.

[0019] 2. The anti-detachment layer effectively reduces the probability of the cable coming off the sub-rod. The rubber strip, in conjunction with the inner pressure roller, increases the friction on the cable, reducing displacement relative to the sub-rod, thus ensuring the stability of the cable position during the process of the endoscope being withdrawn from the borehole.

Detailed Implementation

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] This application discloses a hole-peeping device for use in underground coal mine drilling.

[0027] refer to Figure 1 and Figure 2 The borehole inspection device for underground coal mine drilling includes a support frame 1, a propulsion frame 11, a main rod 2, a secondary rod 3, and clamping wheels 4. The support frame 1 is a tripod, erected below the borehole. The propulsion frame 11 is mounted on top of the support frame 1. The main rod 2 is vertically slidably connected to the propulsion frame, and the inspection device is mounted at the top of the main rod 2. The inspection device's cable extends from the bottom of the main rod 2 and is wound on a cable reel. The two opposite outer walls at the bottom of the main rod 2 have slots 21.

[0028] refer to Figure 2 and Figure 3 The secondary rod 3 has a U-shaped cross-section and is injection molded from plastic in this embodiment. The slot 21 is also located at the bottom of the secondary rod 3. Two opposing inner sidewalls at the top of the secondary rod 3 have locking blocks 31, which can be locked into the slot 21 with an interference fit, allowing the cable to reside within the secondary rod 3. Two clamping wheels 4 are mounted rotatably on top of the push frame 11, and their outer circumferential walls are made of rubber. Both clamping wheels 4 are driven by a motor and are located on both sides of the main rod 2, capable of clamping the opposing sidewalls of the main rod 2 or the secondary rod 3.

[0029] The main rod 2 and the auxiliary rod 3 can be connected by inserting the locking block 31 into the locking slot 21. This method also allows for the connection between the auxiliary rods 3, extending their length. The clamping wheel 4 can move the main rod 2 and the auxiliary rod 3 into the borehole, enabling the automatic pushing of the inspection instrument within the borehole.

[0030] refer to Figure 2 and Figure 3An anti-detachment layer 32 is fixed to the end of the side wall at the opening of the secondary rod 3. The anti-detachment layer 32 is an adhesive sponge. The anti-detachment layer 32 is a soft material that can elastically deform. When the cable enters the secondary rod 3, it will abut against the anti-detachment layer 32. A rubber strip 33 is attached to the inner side wall of the secondary rod 3 facing its own opening. An inner pressure plate 111 is rotatably connected to the push frame 11 below the clamping wheel 4. The inner pressure plate 111 is inclined downward and the bottom end is rotatably connected to an inner pressure wheel 1111. The inner pressure wheel 1111 is made of rubber. A torsion spring is provided on the rotation shaft of the inner pressure plate 111, so that the inner pressure wheel 1111 can squeeze the cable into the inner rod and press it against the rubber strip 33.

[0031] This method allows the inner pressure roller 1111 to automatically squeeze the cable into the secondary rod 3 during the upward movement of the main rod 2. The tight compression between the cable and the rubber strip 33 effectively reduces relative movement between the cable and the secondary rod 3, improving the cable's stability within the secondary rod 3 and thus increasing the efficiency of the probe's advance mechanism. The protective layer effectively reduces the probability of the cable detaching from the secondary rod 3 after entering the borehole, and also protects the cable when it enters the secondary rod 3.

[0032] refer to Figure 1 and Figure 4 The support frame 1 has placement frames 12 on both sides for holding multiple auxiliary rods 3. After the auxiliary rods 3 are removed, they can be placed in the placement frames 12 for unified storage, which also makes it easy to retrieve the auxiliary rods 3. When the auxiliary rods 3 are located in the placement frames 12, their side walls are located inside the adjacent auxiliary rods 3, thus allowing them to be stacked and improving the storage efficiency of the space within the placement frames 12.

[0033] The implementation principle of the borehole inspection device pushing device for underground coal mine drilling according to an embodiment of this application is as follows: After the support frame 1 is set up below the borehole, the auxiliary rod 3 is installed on the main rod 2, and the clamping wheel 4 driven by the motor moves the main rod 2 and the auxiliary rod 3 upward, sending the inspection device into the borehole. The main rod 2 and the auxiliary rod 3, and the auxiliary rod 3 and the auxiliary rod 3 are all installed by sliding and snapping, which improves the efficiency of the inspection device pushing rod installation. During the process of the main rod 2 and the auxiliary rod 3 moving upward together by the clamping wheel 4, the inner pressure wheel 1111 will press the cable into the auxiliary rod 3, thereby automatically realizing the combination of the cable and the auxiliary rod 3, improving the efficiency of the inspection device pushing.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
