Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a convenient fixing device for recording video during pressure relief drilling. Background Technology

[0002] In mines with high impact risks, stress relief drilling is necessary to reduce the stress in the surrounding rock in order to achieve safe production. According to standardized requirements, stress relief drilling must strictly implement the "one hole, one file" system and record the entire construction process. During construction, a suitable area must first be selected for drilling operations. Then, based on the drilling location, a suitable installation position for the explosion-proof camera is determined on the tunnel wall to ensure that the explosion-proof camera can accurately and clearly record the drilling process. After the installation position of the explosion-proof camera is selected, a hole is drilled in the tunnel wall, and then the mounting bracket is fixed to the tunnel wall with expansion bolts. The explosion-proof camera is then fixed with the mounting bracket, and its angle is adjusted so that the lens of the explosion-proof camera is accurately facing the drilling position. Only then can drilling operations be carried out at the designated drilling position.

[0009] Preferably, the top of the buffer wheel and the two positioning wheels are provided with limiting parts, and the bottom of the buffer wheel and the two positioning wheels are provided with protrusions. The opposite surfaces of the limiting parts and the protrusions are respectively attached to the top and bottom of the wire.

[0010] Preferably, the diameter of the limiting portion is smaller than the diameter of the protrusion.

[0011] Preferably, a guide rail is fixed to the bottom of the inner wall of the base body, the inner wall of the guide rail is slidably connected to the side of the guide sleeve, a cavity is opened inside the guide sleeve, a U-shaped retaining strip is slidably connected to the inner wall of the cavity, two slots are opened at the bottom of the inner wall of the guide rail, the end of the U-shaped retaining strip moves through the guide sleeve and is inserted into the slot, a movable block and a tension spring are fixed to the top of the U-shaped retaining strip respectively, the top of the movable block moves through the guide sleeve and fits against the bottom of the guide rod, the tension spring is sleeved on the surface of the movable block, and the top of the tension spring is fixedly connected to the top of the inner wall of the cavity, a notch is opened at the bottom of the guide rod, the notch is located between the guide sleeve and the connecting seat, the inner wall of the notch is provided with a slope on the side away from the connecting seat, a lever is fixed to the top of the guide sleeve, a transparent viewing window is inlaid on the top of the top cover, a long groove is opened on the top of the transparent viewing window, and the top of the lever passes through the inside of the long groove and extends to the top of the transparent viewing window.

[0012] Preferably, a limiting block is fixed at one end of the guide rail near the buffer wheel, and the side of the limiting block fits against the end of the guide sleeve near the buffer wheel.

[0013] Preferably, a handle is fixed to the top of the transparent viewing window, and the handle covers the top of the lever.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, the explosion-proof pan-tilt unit is installed on top of the telescopic pole and the explosion-proof camera is mounted on the pan-tilt unit. The base, telescopic pole, and explosion-proof pan-tilt unit together constitute the bracket for the explosion-proof camera. This bracket can be placed directly on the tunnel floor for use, eliminating the need for cumbersome installation on the tunnel wall. The explosion-proof pan-tilt unit can easily and automatically adjust the angle of the explosion-proof camera to ensure that the lens is accurately pointed at the drilling position, achieving efficient video recording. When video recording is required in other locations, only the bracket needs to be moved, avoiding the trouble of repeatedly installing and fixing the explosion-proof camera, greatly improving ease of use.

[0016] With the help of buffer wheels and springs, the wires are laid along the ground to power the explosion-proof pan-tilt unit and explosion-proof camera and transmit data. During the recording process, when a staff member trips on the wires, the wires will be pulled. Once the wires are pulled and move, the wires will squeeze the buffer wheels, causing the buffer wheels to move and compress the springs. The compression deformation of the springs can effectively relieve the force acting on the bracket when the wires are pulled, preventing the brackets from moving due to the wires being pulled, thereby maintaining the stability of the explosion-proof camera's captured images.

[0017] With the protrusion and limiting part set, the protrusion fits against the bottom of the wire, and the limiting part fits against the top of the wire. When the wire is pulled and the positioning wheel and buffer wheel rotate, the protrusion can provide stable support for the movement of the wire, and the limiting part can realize stable limiting of the movement of the wire. The two work together to effectively prevent the wire from separating from the buffer wheel and positioning wheel during the movement, and ensure that the buffer wheel and positioning wheel can continue to play a stable role.

[0018] By using the locking mechanism and notch design, when the buffer wheel moves and compresses the spring, and the wire pull is large, the buffer wheel moves significantly, causing the spring to compress and deform considerably. During this process, the guide rod moves along the inner wall of the guide sleeve. When the notch on the guide rod aligns with the position of the movable block, the movable block moves upward under the tension of the spring, simultaneously causing the U-shaped locking strip to separate from the slot, releasing the positioning of the guide sleeve. At this point, the guide sleeve can move along the inner wall of the guide rail with the help of the spring force when the buffer wheel moves. As the degree of spring compression and deformation increases, its elasticity increases, and the resistance to the buffer wheel moving when the wire is pulled also increases. The movement of the guide sleeve can reduce the resistance of the spring to the movement of the buffer wheel, further preventing the support from moving due to the wire pull, effectively ensuring the stability and reliability of the explosion-proof camera's captured images.

[0027] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0028] The present invention provides a convenient pressure-relief drilling video recording fixing device in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0029] like Figures 1-5As shown, this embodiment of the present invention provides a convenient fixing device for pressure relief drilling video recording, including a telescopic rod 1, an explosion-proof pan-tilt unit 4 installed on the top of the telescopic rod 1, an explosion-proof camera 5 installed on the rotating end of the explosion-proof pan-tilt unit 4, a wire 25 installed on the side of the explosion-proof pan-tilt unit 4, and a buffer base 6 installed at the bottom of the telescopic rod 1. The above structure forms a bracket to realize the installation and fixing of the explosion-proof camera 5. The telescopic rod 1 can be flexibly adjusted in height to adapt to the shooting needs of different drilling positions. The explosion-proof pan-tilt unit 4 is installed on the top of the telescopic rod 1 and can automatically and accurately adjust the angle of the explosion-proof camera 5 so that the lens is always aimed at the drilling position, realizing efficient and stable video recording. The buffer base 6 provides stable support for the entire device. At the same time, the entire device can be placed directly on the tunnel floor without complicated installation on the tunnel wall, which significantly improves the convenience of use and avoids the tedious operation of repeatedly installing and fixing the camera and adjusting the angle at different tunnel wall positions.

[0030] like Figure 1 As shown, in this embodiment, the telescopic rod 1 includes a rod sleeve fixed to the top of the base body 7. A rod body is slidably connected to the inner wall of the rod sleeve, and a bolt is threadedly connected to the side of the rod sleeve. The bolt is used to fix the height of the rod body. The explosion-proof gimbal 4 is fixed to the top of the rod body. The design of the sliding fit between the rod sleeve and the rod body of the telescopic rod 1 allows for flexible adjustment of the height according to actual shooting needs, meeting the shooting requirements of different drilling operation heights. By loosening the bolts connected by the side threads, the rod body can be moved up or down, thereby raising or lowering the height of the explosion-proof camera 5. After adjusting to a suitable height, the bolts are tightened so that the end of the bolt abuts against the rod body.

[0031] like Figure 3 and Figure 4As shown, in this embodiment, the buffer base 6 includes a base body 7. The bottom of the telescopic rod 1 is fixedly connected to the top of the base body 7. A notch is provided on the top of the base body 7. A top cover 3 is installed at the notch on the top of the base body 7. A guide sleeve 16 is provided inside the base body 7. A guide rod 14 is slidably connected to the inner wall of the guide sleeve 16. A connecting seat 13 is fixed to the end of the guide rod 14. A spring 15 is fixed between the connecting seat 13 and the guide sleeve 16. The spring 15 is sleeved on the guide rod 14. A round shaft surface fixedly connected to the inner wall of the connecting seat 13 rotates. A buffer wheel 10 is connected to the base body 7. A rotating shaft 9 is fixed to the bottom of the inner wall of the base body 7. Two positioning wheels 8 are rotatably connected to the top of the rotating shaft 9. The buffer wheel 10 is located between the two positioning wheels 8. The end of the wire 25 away from the explosion-proof gimbal 4 passes through the top of the base body 7, passes around the positioning wheels 8 and the buffer wheel 10, and then passes out from the side of the base body 7. A fixing seat is fixed inside the base body 7. The fixing seat is used to fix the wire 25 near the telescopic rod 1. The wire 25 first passes through the top of the base body 7, then passes through the fixing seat, passes around the left positioning wheel 8, and then passes around... After the buffer wheel 10 bends and passes through the right positioning wheel 8, it exits from the right side of the base body 7. Then, the connector at the end of the wire 25 is connected to the cable installed in the tunnel. When a worker accidentally trips over the wire 25, causing it to move, the wire 25, under the influence of the right positioning wheel 8, will squeeze the buffer wheel 10, causing it to rotate and move. This, in turn, compresses the spring 15 through the connecting seat 13, causing the spring 15 to deform. The deformation of the spring 15 effectively counteracts the force exerted on the support when the wire 25 is pulled, preventing… The bracket shifts due to the pulling of the wire 25, maintaining the stability of the image captured by the explosion-proof camera 5. The positioning wheel 8 guides the wire 25, ensuring that the movement path of the wire 25 is relatively stable during the pulling process. The notch at the top of the base body 7 and the design of the top cover 3 facilitate the insertion of the wire 25 during installation and subsequent maintenance. The fixing seat fixes the wire 25 near the telescopic rod 1, preventing the wire 25 located above the base body 7 from moving when it is pulled, thereby further reducing the possibility of the bracket moving when the wire 25 moves due to the pulling.

[0032] like Figure 4 and Figure 5As shown, in this embodiment, the top of the buffer wheel 10 and the two positioning wheels 8 are provided with limiting parts 11, and the bottom of the buffer wheel 10 and the two positioning wheels 8 are provided with protrusions 12. The opposite surfaces of the limiting parts 11 and the protrusions 12 are respectively attached to the top and bottom of the wire 25. When the wire 25 is pulled, causing the positioning wheels 8 and the buffer wheel 10 to rotate, the protrusions 12 are attached to the bottom of the wire 25, providing stable support for the movement of the wire 25. The limiting parts 11 are attached to the top of the wire 25, achieving stable limiting of the movement of the wire 25 and preventing the wire 25 from separating from the buffer wheel 10 and the positioning wheels 8. This ensures that the buffer wheel 10 and the positioning wheels 8 continue to stably play a buffering and guiding role for the wire 25, further ensuring that the device can effectively buffer and maintain the stability of the captured image when the wire 25 is pulled.

[0033] like Figure 5 As shown, in this embodiment, the diameter of the limiting part 11 is smaller than the diameter of the protrusion 12. The design that the diameter of the limiting part 11 is smaller than the diameter of the protrusion 12 ensures the limiting and supporting effect on the wire 25, while making it simpler and more convenient for the wire 25 to pass through the buffer wheel 10 and the positioning wheel 8.

[0034] like Figure 3 and Figure 4As shown, in this embodiment, a guide rail 23 is fixed to the bottom of the inner wall of the base body 7. The inner wall of the guide rail 23 is slidably connected to the side of the guide sleeve 16. A cavity is opened inside the guide sleeve 16, and a U-shaped retaining strip 18 is slidably connected to the inner wall of the cavity. Two retaining slots 19 are opened at the bottom of the inner wall of the guide rail 23. The end of the U-shaped retaining strip 18 moves through the guide sleeve 16 and is inserted into the inside of the retaining slot 19. A movable block 17 and a tension spring 22 are fixed to the top of the U-shaped retaining strip 18 respectively. The top of the movable block 17 moves through the guide sleeve 16 and fits against the bottom of the guide rod 14. The tension spring 22 is sleeved... The top of the tension spring 22 is fixedly connected to the top of the inner wall of the cavity, and a notch 20 is provided at the bottom of the guide rod 14. The notch 20 is located between the guide sleeve 16 and the connecting seat 13. An inclined surface 21 is provided on the inner wall of the notch 20 away from the connecting seat 13. A lever 24 is fixed to the top of the guide sleeve 16. A transparent viewing window is embedded in the top of the upper cover 3. A long groove is provided on the top of the transparent viewing window. The top of the lever 24 passes through the long groove and extends to the top of the transparent viewing window. When the buffer wheel 10 moves significantly under the pulling force of the wire 25, the spring... When the spring 15 undergoes significant compression deformation, the guide rod 14 moves along the inner wall of the guide sleeve 16 until the notch 20 at the bottom of the guide rod 14 corresponds to the position of the movable block 17. At this time, the movable block 17 moves upward under the tension of the tension spring 22 and inserts into the notch 20. When the movable block 17 moves upward, it causes the U-shaped retaining strip 18 to separate from the retaining groove 19, releasing the positioning of the guide sleeve 16. At this time, the guide sleeve 16 can move along the inner wall of the guide rail 23 with the help of the elastic force of the spring 15 when the buffer wheel 10 moves. As the degree of compression deformation of the spring 15 increases, its elastic force increases, and when the wire 25 is pulled and moved... The resistance to moving the buffer wheel 10 also increases, while the movement of the guide sleeve 16 can reduce the resistance of the spring 15 to the movement of the buffer wheel 10, further preventing the support from moving due to the pulling of the wire 25, which effectively ensures the stability and reliability of the image captured by the explosion-proof camera 5. At the same time, the transparent window design allows the operator to observe the situation inside the transparent window from outside the device. The toggle block 24 can be used to easily reset the guide sleeve 16 and the buffer wheel 10. After the guide sleeve 16 is reset, the buffer wheel 10 can be automatically reset. The operation is simple and convenient.

[0035] like Figure 4 As shown, in this embodiment, a limiting block is fixed at one end of the guide rail 23 near the buffer wheel 10. The side of the limiting block is in contact with the end of the guide sleeve 16 near the buffer wheel 10. The setting of the limiting block restricts the movement of the guide sleeve 16, ensuring that when the guide sleeve 16 is in contact with the limiting block, the U-shaped card strip 18 and the card slot 19 are in corresponding positions.

[0036] like Figure 1As shown in this embodiment, a handle 2 is fixed to the top of the transparent viewing window. The handle 2 covers the top of the lever 24. The handle 2 is designed to facilitate the removal and placement of the top cover 3 when disassembling it. At the same time, the handle 2 covers the top of the lever 24, which can provide a certain degree of protection for the lever 24 and prevent accidental contact with the lever 24.

[0037] Working principle: The support consists of a telescopic rod 1, an explosion-proof pan-tilt head 4, an explosion-proof camera 5, and a buffer base 6, which is used to fix the explosion-proof camera 5. The explosion-proof pan-tilt head 4 is installed on the top of the rod, and the explosion-proof camera 5 is mounted on its rotating end. The base body 7 and the telescopic rod 1 together support the entire device. This design allows the support to be placed directly on the tunnel floor without complicated installation on the tunnel wall. During operation, the explosion-proof pan-tilt head 4 can automatically and accurately adjust the angle of the explosion-proof camera 5 so that its lens is aligned with the drilling position. When it is necessary to change the working area, only the entire support needs to be moved, avoiding the tedious operation of repeatedly installing, fixing and adjusting the camera at different tunnel wall positions, which significantly improves the ease of use.

[0038] The wire 25 is laid along the ground and serves to provide power and data transmission for the explosion-proof pan-tilt unit 4 and the explosion-proof camera 5. The buffer wheel 10, positioning wheel 8 and spring 15 in the buffer base 6 work together to ensure image stability. When a staff member accidentally trips over the wire 25 and it is pulled and moved, the wire 25 will squeeze the buffer wheel 10 due to the influence of the positioning wheel 8 on the right side during the movement. This causes the buffer wheel 10 to rotate and move, which in turn squeezes the spring 15 through the connecting seat 13, causing the spring 15 to compress and deform. At the same time, the connecting seat 13 drives the guide rod 14 to move along the inner wall of the guide sleeve 16. The compression deformation of the spring 15 can effectively counteract the force applied to the bracket when the wire 25 is pulled, preventing the bracket from shifting due to the pulling of the wire 25 and maintaining the stability of the image captured by the explosion-proof camera 5.

[0039] The buffer wheel 10 and the positioning wheel 8 are provided with a limiting part 11 at the top and a protrusion 12 at the bottom. When the wire 25 is pulled, causing the positioning wheel 8 and the buffer wheel 10 to rotate, the protrusion 12 fits against the bottom of the wire 25, providing stable support for the movement of the wire 25. The limiting part 11 fits against the top of the wire 25, achieving stable limiting of the movement of the wire 25. The two work together to effectively prevent the wire 25 from separating from the buffer wheel 10 and the positioning wheel 8 during movement, ensuring that the buffer wheel 10 and the positioning wheel 8 continuously and stably perform their buffering and guiding functions for the wire 25.

[0040] Inside the base body 7, the guide rail 23 cooperates with the guide sleeve 16 to guide the movement of the guide sleeve 16. The U-shaped retaining strip 18 inside the guide sleeve 16 is inserted into the slot 19 on the guide rail 23 to achieve the positioning of the guide sleeve 16. When the buffer wheel 10 moves significantly under the pulling force of the wire 25, causing the spring 15 to be compressed and deformed significantly, the guide rod 14 moves along the inner wall of the guide sleeve 16 until the notch 20 at the bottom of the guide rod 14 corresponds to the position of the movable block 17. After the correspondence, the movable block 17 moves upward under the pulling force of the tension spring 22 and inserts into the notch 20. When the 7th movement moves upward, it causes the U-shaped clip 18 to separate from the slot 19, releasing the positioning of the guide sleeve 16. At this time, the guide sleeve 16 can move along the inner wall of the guide rail 23 with the help of the spring force of the spring 15 when the buffer wheel 10 moves. As the compression deformation of the spring 15 increases, its elastic force increases, and the resistance of the buffer wheel 10 moving when the wire 25 is pulled also increases. The movement of the guide sleeve 16 can reduce the resistance of the spring 15 to the movement of the buffer wheel 10, further preventing the support from moving due to the pulling of the wire 25, and effectively ensuring the stability and reliability of the image captured by the explosion-proof camera 5.

[0041] When the pull of the guide wire 25 on the buffer wheel 10 disappears and the guide sleeve 16 needs to be reset after movement, simply move the lever 24 so that the lever 24 drives the guide sleeve 16 to move in the opposite direction along the inner wall of the guide rail 23. The guide sleeve 16 drives the U-shaped retaining strip 18 to move in the opposite direction until the guide sleeve 16 is in contact with the side of the limiting block. After contact, the guide sleeve 16 stops moving. At this time, the position of the U-shaped retaining strip 18 corresponds to the position of the retaining groove 19. Under the elastic force of the spring 15, the connecting seat 13 drives the guide rod 14 to move in the opposite direction along the inner wall of the guide sleeve 16. The inclined surface 21 of the inner wall of the notch 20 on the guide rod 14 Squeezing the movable block 17 causes it to move downwards. The movable block 17 drives the U-shaped retaining strip 18 downwards and puts the tension spring 22 in a stretched state. After the U-shaped retaining strip 18 moves downwards, it inserts into the retaining groove 19 to reposition the guide sleeve 16. At the same time, when the connecting seat 13 moves in the opposite direction under the elastic force of the spring 15, the connecting seat 13 drives the buffer wheel 10 to move in the opposite direction. During the reverse movement of the buffer wheel 10, the wire 25 is pulled in the opposite direction, thereby realizing the reset of the wire 25. The reset status of the buffer wheel 10 and the guide can be directly observed through the transparent window, making it more convenient to use.
