Description

Technical Field

[0001] The present invention belongs to the technical field of mining equipment, and relates to a fixing bracket device for a monitoring camera in a coal mine underground tunnel. The present invention also relates to an implementation method of the above device. Background Art

[0002] With the popularity of surveillance cameras in underground mine tunnels, "no video, no work" has become a prerequisite for safe production. Therefore, it is necessary to install cameras at various locations in the underground tunnels to monitor the work situation and upload it to the ground dispatching and command center. Due to the change of work location, the underground tunnel surveillance cameras need to be frequently disassembled and moved. Most of the existing coal mine underground tunnel surveillance cameras fix the camera on the exposed screw of the roof anchor (anchor cable) and lock it with screws. Every time the work location is advanced or changed, it is necessary to disassemble and move, go up and down the ladder, and suspend the camera at high altitude. The installation is difficult, and there are great safety hazards in high-altitude operations.

[0003] The invention patent with application number 202322383837.6 discloses a quick-release monitoring bracket for mining. The key points of its technical solution include a U-shaped support frame and a video surveillance camera. The problem of needing screw fixation is solved by setting a quick-release wrench. Since the top of the quick-release wrench is fixedly connected to the rotating block, the insert rod passes through the fixed block and extends to the inside of the rotating block, so the quick-release wrench can be rotated. When the quick-release wrench is rotated upward, the quick-release buckles fixed on both sides of the quick-release wrench also move accordingly. Since the quick-release buckles are installed on both sides of the connecting rod, the connecting rod and the rotating sleeve are connected, and the rotating sleeve is arranged on the surface of the rotating rod, the quick-release wrench can be rotated with the quick-release buckle without getting stuck, which is convenient for use.

[0004] The quick-release wrench in this invention has a complex structure, many parts, and high cost. It is easily damaged when frequently disassembled, and the disassembly is time-consuming and labor-intensive. It cannot effectively guarantee the safety of the operator during operation, and the rotation of the camera is only a rotation in one plane, which cannot fully cover the required monitoring positions.

[0015] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Figure 1 The first embodiment of the fixing bracket device of the underground coal mine tunnel monitoring camera of the present invention is shown, which is in a vertical direction when in use, and includes a locking assembly 100, and the locking assembly 100 and the horizontal fixing base 202 are connected by a universal adjustment mechanism 300. The camera device is detachably mounted on the horizontal fixing base 202.

[0017] like Figure 2 The specific structural diagram of the device of the present invention is shown, the locking assembly 100 includes a vertical conduit 101 and a vertical guide rod 108, the upper end of the vertical guide rod 108 extends into the lower part of the vertical conduit 101, and can move up and down inside the vertical conduit 101, and a through groove along the length of the vertical conduit 101 is opened in the middle of the wall of the vertical conduit 101, and a clamping mechanism is installed at the through groove to clamp the anchor rod or anchor cable extending into the vertical conduit 101. A locking adjustment mechanism is installed on the upper part of the vertical guide rod 108 to adjust the tightness of the clamping mechanism.

[0018] Furthermore, the clamping mechanism has two groups of clamping assemblies symmetrically arranged along the central axis of the vertical conduit 101. The clamping assembly includes two groups of connecting rods 110 at the lower part of the through slot, and the two groups of connecting rods are symmetrical to the side wall of the conduit 101. The connecting rod 110 is hinged to one end of the clamping jaw 102, and the clamping part of the other end of the clamping jaw 102 extends into the through slot. The upper end of the vertical guide rod 108 is hinged to one end of the locking link 103, and the other end of the locking link 103 passes through the through slot and is hinged to the middle part of the clamping jaw 102.

[0019] Furthermore, the locking and adjusting mechanism includes a locking nut 107, which is threadedly connected to the middle part of the vertical guide rod 108, and a locking spring 106 is arranged on the middle part of the vertical guide rod 108. A limit screw 104 is passed through the lower end of the vertical guide tube 101, and the locking spring 106 is located between the limit screw 104 and the locking nut 107. By adjusting the position of the locking nut 107, the elastic force of the locking spring 106 on the vertical guide rod 108 can be controlled.

[0020] The lower end of the vertical conduit 101 is fixedly connected to an external shield 105 , and the external shield 105 covers the locking spring 106 to prevent the locking mechanism from being exposed to rain and thus reducing its service life.

[0021] like Figure 3 As shown, the universal adjustment mechanism 300 includes a ball head 109 and a ball head cover 203 that are matched and connected. The ball head 109 is fixedly installed on the lower end of the vertical guide rod 108, and the ball head cover 203 is fixedly installed on the horizontal fixed base 202.

[0022] The outer wall of the ball head cover 203 has a threaded through hole that leads into the inner cavity of the ball head cover. The adjusting screw 201 is installed in the threaded through hole. The tail of the adjusting screw 201 is a flat head. The flat head abuts against the ball head 109 to generate mutual friction with the ball head 109. The tightness and rotation of the universal adjustment mechanism are controlled by controlling the position of the adjusting screw 201. The horizontal fixed base 202 has multiple threaded mounting holes to facilitate the fixed installation of camera equipment, and can be suitable for the installation of various camera equipment.

[0023] The present invention also provides an implementation method of the device in the above embodiment, which is implemented specifically according to the following steps: Step 1: Fix the camera device on the horizontal fixed base 202; Step 2, put the vertical guide tube 101 on the anchor rod or anchor cable, and push the vertical guide rod 108 upward at the same time, the vertical guide rod 108 drives the clamping claw 102 in the clamping mechanism to open outward, and adjust the position of the device of the present invention clamped on the anchor rod or anchor cable; Step 3, after the device of the present invention is installed in place, release the driving force on the vertical guide rod 108, the gravity of the camera and the horizontal fixed base 202, and the elastic force of the locking spring 106 in the locking adjustment structure, so that the vertical guide rod 108 moves downward, driving the clamping claw 102 of the clamping mechanism to clamp the anchor rod or anchor cable; Step 4: Loosen the adjustment screw 201 of the universal adjustment mechanism, adjust the camera to the required direction, and then tighten the adjustment screw 201 to fix the direction; Step 5: When the device of the present invention needs to be moved, the vertical guide rod 108 is pushed to drive the clamping claws 102 in the clamping mechanism to open and then the device can be removed.

[0024] The second embodiment of the present invention includes a locking assembly 100, which is connected to a horizontal fixed base 202 via a universal adjustment mechanism 300. The camera device can be detachably mounted on the horizontal fixed base 202. The horizontal fixed base 202 is configured as a regular hexahedron, and a plurality of mounting holes are evenly arranged on the outer surface of the regular hexahedron, so that the camera device can be installed on different surfaces at the same time.

[0025] The locking assembly 100 includes a vertical conduit 101 and a vertical guide rod 108. The upper end of the vertical guide rod 108 extends into the lower part of the vertical conduit 101 and can move up and down inside the vertical conduit 101. A through groove along the length of the vertical conduit 101 is opened in the middle of the wall of the vertical conduit 101. A clamping mechanism is installed at the through groove to clamp the anchor rod or anchor cable extending into the vertical conduit 101. A locking adjustment mechanism is installed on the upper part of the vertical guide rod 108 to adjust the tightness of the clamping mechanism.

[0026] The difference between this embodiment and the first embodiment is that the horizontal fixed base 202 is set as a regular hexahedron. The structure of the regular hexahedron is simple to process and easy to install the camera. In combination with the universal adjustment mechanism, the camera monitoring range can be covered more widely.

[0027] The implementation method of the device in the second embodiment is specifically implemented according to the following steps: Step 1: Install camera devices on different surfaces of the horizontal fixed base 202; Step 2, put the vertical guide tube 101 on the anchor rod or anchor cable, and push the vertical guide rod 108 upward at the same time, the vertical guide rod 108 drives the clamping claw 102 in the clamping mechanism to open outward, and adjust the position of the device of the present invention clamped on the anchor rod or anchor cable; Step 3, after the device of the present invention is installed in place, release the driving force on the vertical guide rod 108, the gravity of the camera and the horizontal fixed base 202, and the elastic force of the locking spring 106 in the locking adjustment structure, so that the vertical guide rod 108 moves downward, driving the clamping claw 102 of the clamping mechanism to clamp the anchor rod or anchor cable; Step 4: Loosen the adjustment screw 201 of the universal adjustment mechanism, adjust the camera to the required direction, and then tighten the adjustment screw 201 to fix the direction; Step 5: When the device of the present invention needs to be moved, the vertical guide rod 108 is pushed to drive the clamping claw 102 in the clamping mechanism to open, and the device of the present invention and the camera device installed on its horizontal fixed base can be removed.

[0028] The third embodiment of the present invention includes a locking assembly 100 . The locking assembly 100 and the horizontal fixed base 202 are connected via a universal adjustment mechanism 300 . The camera device is detachably mounted on the horizontal fixed base 202 .

[0029] The locking assembly 100 includes a vertical conduit 101 and a vertical guide rod 108. The upper end of the vertical guide rod 108 extends into the lower part of the vertical conduit 101 and can move up and down inside the vertical conduit 101. A through groove along the length of the vertical conduit 101 is opened in the middle of the wall of the vertical conduit 101. A clamping mechanism is installed at the through groove, which can clamp the anchor rod or anchor cable extended into the vertical conduit 101.

[0030] A locking adjustment mechanism is installed on the upper part of the vertical guide rod 108 to adjust the tightness of the clamping mechanism. The clamping mechanism has two groups of clamping components that are symmetrical left and right along the central axis of the vertical conduit 101. The clamping components include a connecting rod 110 symmetrical to the side wall of the conduit 101 at the lower part of the through-groove. The connecting rod 110 is hinged to one end of the clamping jaw 102, and the clamping part of the other end of the clamping jaw 102 extends into the through-groove. The upper end of the vertical guide rod 108 is hinged to one end of the locking link 103, and the other end of the locking link 103 passes through the through-groove and is hinged to the middle of the clamping jaw 102. The reduction of the connecting rod 110 reduces the difficulty of processing, saves labor and cost, but the stability during use is slightly lower than that of the first embodiment.

[0031] The implementation steps of this embodiment are the same as those of the first embodiment described above, and will not be repeated here.
