Description

Technical Field

[0001] This utility model belongs to the field of coal mine gas drainage pipeline installation technology, and specifically relates to an auxiliary bracket for the installation of coal mine gas drainage pipelines. Background Technology

[0002] Auxiliary brackets are needed during the installation of coal mine gas drainage pipelines.

[0003] Existing auxiliary brackets for installing coal mine gas drainage pipelines, while meeting the basic requirements for supporting and fixing the pipelines, typically use a spliced ​​fixing structure. These spliced ​​structures can only move vertically relative to each other, meaning the pipeline can only be placed and removed after the entire fixing structure is disassembled. This not only increases the user's workload but also reduces the overall efficiency of pipeline installation and disassembly. Furthermore, the process of completely separating the spliced ​​fixing structure increases the risk of it falling from a height during disassembly and assembly. Therefore, it fails to fully meet the user's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing an auxiliary support bracket for the installation of coal mine gas drainage pipelines. It not only meets the basic requirements for supporting the installation of gas drainage pipelines, but also allows users to disassemble and install the drainage pipelines without completely dismantling the fixed structure, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an auxiliary bracket for the installation of a coal mine gas drainage pipeline, including an installation plate set on the side wall of the coal mine, a horizontal plate that can be vertically lifted and lowered on the installation plate, a lifting groove on the horizontal plate, a vertical rod located at the side end of the lower lifting groove on the horizontal plate, a pressure groove that can slide vertically and rotate on the vertical rod, and a fixing bolt for fixing the lifting groove is screwed onto the pressure groove.

[0006] As a further improvement of this utility model, the mounting plate is provided with a mounting groove, an adjusting screw is rotatably mounted in the mounting groove, a handle for driving the adjusting screw to rotate is provided on the mounting groove, a mounting block is screwed onto the adjusting screw and slidably connected to the mounting groove, and the mounting block is connected to the horizontal plate.

[0007] As a further improvement of this utility model, a first reinforcing plate is provided between the bottom of the mounting block and the horizontal plate, and a second reinforcing plate is provided between the top of the mounting block and the horizontal plate.

[0008] As a further improvement of this utility model, a sliding connecting plate is provided between the upper and lower ends of the mounting groove, a connecting sliding hole is provided on the mounting block to slide and connect with the sliding connecting plate, and a locking bolt is screwed onto the mounting block to abut against the outer wall of the sliding connecting plate to fix the connection between the mounting block and the sliding connecting plate.

[0009] As a further improvement of this utility model, the side end of the pressure groove is provided with a vertical cylinder that is slidably and rotatably connected to the vertical rod.

[0010] As a further improvement of this utility model, the top side of the lifting groove is also provided with a snap-fit ​​groove, and the bottom side of the pressing groove is also provided with a snap-fit ​​protrusion that snaps into the snap-fit ​​groove.

[0011] As a further improvement of this utility model, the sliding connecting plate is also provided with a receiving groove that is misaligned with the locking bolt, and the sliding connecting plate is provided with a scale line located in the receiving groove.

[0012] As a further improvement of this utility model, the mounting plate is fixedly installed on the side wall of the coal mine by anchor bolts, with the anchor bolts penetrating at least 150mm into the rock layer of the coal mine side wall. The mounting plate is provided with mounting holes for installing the anchor bolts, and shock-absorbing pads are also provided on the inner side wall of the mounting plate. The installation plate is equipped with shock-absorbing pads on the inner side and is fixed by anchor bolts penetrating at least 150mm into the rock layer. This not only enhances the impact resistance of the device but also effectively reduces the transmission of vibration in the underground environment, extending the service life of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, by setting up a vertically sliding and rotating pressure groove, which is used in conjunction with the support groove, when installing or disassembling the gas extraction pipeline, it is not necessary to completely disassemble the entire fixed structure. Simply adjust the vertical position of the pressure groove and rotate it to quickly install or remove the extraction pipeline, which significantly improves maintenance and replacement efficiency.

[0015] Secondly, the horizontal plate can be raised and lowered vertically via an adjusting screw and driven by a handle, making operation simple and adjustment precise. Combined with the scale lines on the sliding connecting plate, users can intuitively grasp the raising and lowering position of the horizontal plate, meeting the needs of different installation heights and adapting to complex tunnel environments.

[0016] Third, the connection strength between the mounting block and the horizontal plate is enhanced by using a first and a second reinforcing plate; at the same time, the mounting block is fixed to the sliding connecting plate by locking bolts, which effectively prevents loosening caused by vibration during operation and improves the stability and safety of the overall structure.

[0017] Fourth, the bottom of the pressure groove is equipped with a snap-fit ​​protrusion, which cooperates with the snap-fit ​​groove on the lifting groove to achieve precise positioning; then, it is locked by fixing bolts to ensure that the pipeline will not be displaced or fall off in the working state, thus ensuring the continuous and stable operation of the gas extraction system.

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 As shown, an auxiliary bracket for installing a coal mine gas drainage pipeline includes an installation plate 101 installed on the side wall of the coal mine. The installation plate 101 is provided with a horizontal plate 102 that can be vertically raised and lowered. The horizontal plate 102 is provided with a lifting groove 103. The horizontal plate 102 is also provided with a vertical rod 104 located at the side end of the lower lifting groove 103. The vertical rod 104 is provided with a pressure groove 105 that can slide vertically and rotate. The pressure groove 105 is also screwed with a fixing bolt 106 for fixing the lifting groove 103.

[0023] like Figure 1 As shown, the mounting plate 101 is provided with a mounting groove 107, an adjusting screw 108 is rotatably disposed in the mounting groove 107, and a handle 109 is provided on the mounting groove 107 for driving the adjusting screw 108 to rotate. A mounting block 110 is screwed onto the adjusting screw 108 and slidably connected to the mounting groove 107. The mounting block 110 is connected to the horizontal plate 102.

[0024] like Figure 2 As shown, a first reinforcing plate 201 is provided between the bottom of the mounting block 110 and the horizontal plate 102, and a second reinforcing plate 202 is provided between the top of the mounting block 110 and the horizontal plate 102.

[0025] like Figure 1 As shown, a sliding connecting plate 203 is also provided between the upper and lower ends of the mounting groove 107. The mounting block 110 is provided with a connecting sliding hole 204 that is slidably connected to the sliding connecting plate 203. The mounting block 110 is also screwed with a locking bolt 205 that can abut against the outer wall of the sliding connecting plate 203 to fix the connection between the mounting block 110 and the sliding connecting plate 203.

[0026] like Figure 1 , 2 As shown in Figure 3, the side end of the pressure groove 105 is provided with a vertical cylinder 111 that is slidably and rotatably connected to the vertical rod 104.

[0027] like Figure 2 , 3 As shown, the top side of the lifting groove 103 is also provided with a snap-fit ​​groove 112, and the bottom side of the pressing groove 105 is also provided with a snap-fit ​​protrusion 113 that snaps into the snap-fit ​​groove 112.

[0028] like Figure 1 As shown, the mounting plate 101 is fixedly installed on the sidewall of the coal mine by anchor bolts. The anchor bolts penetrate at least 150mm into the rock layer of the coal mine sidewall. The mounting plate 101 is provided with mounting holes 114 for installing the anchor bolts, and shock-absorbing pads are also provided on the inner sidewall of the mounting plate 101. The installation plate 101 is equipped with shock-absorbing pads on its inner side and is fixed by anchor bolts penetrating at least 150mm into the rock layer. This not only enhances the impact resistance of the device but also effectively reduces the transmission of vibration in the underground environment, extending the service life of the equipment.

[0029] First, the mounting plate 101 is fixed to the side wall of the coal mine roadway using anchor bolts, ensuring that the anchor bolts penetrate at least 150mm into the rock layer to guarantee the stability of the structure. The inner side of the mounting plate 101 is equipped with shock-absorbing pads, which can effectively absorb vibrations in the underground environment, improving the durability and safety of the device.

[0030] According to the actual installation requirements, the operator turns the crank handle, which drives the adjusting screw 108 to rotate, thereby driving the mounting block 110 to move up and down along the sliding connecting plate 203. Since the mounting block 110 is connected to the horizontal plate 102 through the first reinforcing plate 201 and the second reinforcing plate 202, the horizontal plate 102 can achieve precise vertical raising and lowering. When the target height is reached, the mounting block 110 can be fixed to the sliding connecting plate 203 by locking bolts 205 to prevent positional displacement due to vibration.

[0031] Next, the gas extraction pipeline is placed in the support groove 103 on the horizontal plate 102. At this time, the clamping groove 105 is located on the vertical rod 104 and can slide and rotate along the vertical rod 104 through the vertical cylinder 111 structure. During operation, the clamping groove 105 is first slid upward a certain distance so that the locking protrusion 113 at its bottom disengages from the locking groove 112 on the support groove 103, providing space for the pipeline to be inserted. After the pipeline is in place, the clamping groove 105 is slid down to the corresponding position and rotated so that the locking protrusion 113 is accurately embedded into the locking groove 112 of the support groove 103, completing the initial positioning.

[0032] After adjustment, tighten the fixing bolts 106 to firmly connect the pressure groove 105 and the support groove 103, thereby firmly fixing the gas extraction pipeline on the bracket to prevent it from loosening or falling off during operation and ensuring the safe and stable operation of the system.

[0033] When pipeline needs to be inspected or replaced, simply reverse the operation: loosen the fixing bolt 106, slide upward and rotate the clamping groove 105 to make the locking protrusion 113 exit the locking groove 112, and the pipeline can be easily removed without dismantling the entire bracket structure, which greatly improves maintenance efficiency.

[0034] The entire system ensures stability through multiple reinforcement measures: including the first reinforcement plate 201 and the second reinforcement plate 202 to enhance the connection strength between the horizontal plate 102 and the mounting block 110; the locking bolt 205 to further fix the relative position between the mounting block 110 and the sliding connecting plate 203; at the same time, the snap-fit ​​cooperation between the pressure groove 105 and the support groove 103 and the bolt locking mechanism work together to improve the overall vibration resistance and load-bearing capacity.

[0035] According to another embodiment of the present invention, as shown in the figure, the sliding connecting plate 203 is also provided with a receiving groove 301 that is misaligned with the locking bolt 205, and the sliding connecting plate 203 is provided with a scale line 302 located in the receiving groove 301.

[0036] The scale lines 302 on the sliding connecting plate 203 help the operator visually read the current height position of the horizontal plate 102, ensuring that the installation requirements are met under different tunnel spaces. The receiving groove 301 can prevent the scale lines 302 from being easily worn by the mounting block 110.

[0037] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
