Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, and more specifically, to a fixed support for a camera suitable for underground roadways in coal mines. Background Technology

[0002] Mining areas are high-risk environments, and some dangers and accidents are inevitable. Especially in underground mining operations, it is difficult to detect and control hidden hazards in a timely manner, which brings certain risks to the production and operation of mining areas. Therefore, the installation of monitoring cameras in mining areas is beneficial to reducing the risks of mining production.

[0003] Existing cameras are mostly supported and fixed by traditional mounting brackets during installation. However, due to the special installation environment in the tunnels, it is difficult for the cameras to achieve the required installation state, resulting in the problem of monitoring image deviation and affecting the safety monitoring effect in the mine tunnels.

[0004] Based on this, a camera mounting bracket suitable for underground coal mine roadways is proposed. Summary of the Invention

[0006] To achieve the above objectives, this utility model provides a camera mounting bracket suitable for underground coal mine roadways, including a mounting base. An L-shaped first hinge frame is fixedly installed on the middle of both sides of the outer surface of the mounting base. An adjusting screw is spirally inserted into the middle of the upper surface of the mounting base. A hinge shaft is movably embedded at the output end of the adjusting screw. A second hinge frame is movably mounted on both ends of the outer surface of the hinge shaft. The other end of the second hinge frame is movably connected to the outer surface of the vertical end of the first hinge frame.

[0007] A connecting plate is movably mounted on the lower surface of the fixed base. A connecting seat is fixedly mounted on the middle of the lower surface of the connecting plate.

[0027] Please see Figures 1-5As shown, a camera mounting bracket suitable for underground coal mine roadways includes a mounting base 1. An "L"-shaped first hinge frame 101 is fixedly installed on the middle of both sides of the outer surface of the mounting base 1. An "L"-shaped fixing ear 102 is fixedly installed on the upper surface of the vertical end of the first hinge frame 101. The vertical and horizontal ends of the first hinge frame 101 and the fixing ear 102 are connected by a movable structure.

[0028] An adjusting screw 2 is spirally inserted into the middle of the upper surface of the fixed base 1. A hinge shaft 201 is movably embedded in the output end of the adjusting screw 2. A second hinge frame 202 is movably sleeved on both ends of the outer surface of the hinge shaft 201. The other end of the second hinge frame 202 is movably connected to the outer surface of the vertical end of the first hinge frame 101.

[0029] A connecting plate 3 is movably installed on the lower surface of the fixed base 1. The lower surface of the fixed base 1 is concave in the middle. A groove is opened in the middle of the inner ring surface of the concave part of the fixed base 1. A rubber ring 301 is fixedly installed on the upper surface of the connecting plate 3. The rubber ring 301 is movably embedded in the groove. An assembly screw 302 is opened through the middle of the lower surface of the connecting plate 3.

[0030] A connecting seat 4 is fixedly installed in the middle of the lower surface of the connecting plate 3. An assembly screw block 401 is fixedly installed in the middle of the upper surface of the connecting seat 4. The assembly screw block 401 is screwed into the assembly screw hole 302. A connecting ear 402 is fixedly installed in the middle of the lower surface of the connecting seat 4. A scissor-type adjustment frame 5 is movably installed on the inner ring surface of the connecting ear 402. The scissor-type adjustment frame 5 consists of four sets of connecting frames hinged together. A locking screw ring 501 is fixedly installed at the hinge of each of the four sets of connecting frames.

[0031] The other end of the scissor-type adjustment frame 5 is movably fitted with an assembly seat 6. The rear end of the outer surface of the assembly seat 6 is provided with a mating groove 601 on both sides, and the four sides of the lower surface of the assembly seat 6 are provided with assembly screw holes 602.

[0032] In use, this utility model can first control the adjusting screw 2 to rotate clockwise and counterclockwise according to the installation position in the coal mine roadway, thereby driving the second hinge frame 202 to unfold and close. During the unfolding and closing of the second hinge frame 202, since it is in a movable hinged state with the first hinge frame 101, the unfolding and closing of the second hinge frame 202 pushes the first hinge frame 101 to unfold and close, thereby achieving the effect of adjusting the installation position of the fixing ear 102, so that the fixing ear 102 fits more closely with the installation environment of the coal mine roadway wall. When the fixing ear 102 is adjusted to a suitable installation position, since the fixing ear 102 is in a movable and adjustable state, the unfolded state of the fixing ear 102 is adjusted to fit with the coal mine roadway wall, and the fixing component fixes the fixing ear 102 to the coal mine roadway wall.

[0033] Once the fixing lug 102 is fixedly connected to the coal mine roadway wall, it indicates that the fixing seat 1 is installed and fixed. At this time, the mounting seat 6 can be flipped open from the folded state, and the camera can be fixedly connected to the mounting seat 6 by passing through the mounting screw hole 602 with the fixing component. When the camera needs to adjust the installation height and angle, the locking screw ring 501 set at the movable hinge of the scissor-type adjustment frame 5 can be loosened. At this time, the extension and retraction of the scissor-type adjustment frame 5 can be controlled. When the scissor-type adjustment frame 5 retracts, it can move the mounting seat 6 closer to the coal mine roadway wall, raising the monitoring height of the camera. When the scissor-type adjustment frame 5 unfolds, it can move the mounting seat 6 away from the coal mine roadway wall, lowering the monitoring height of the camera. At the same time, when the locking screw ring 501 at the movable hinge of the mounting seat 6 and the scissor-type adjustment frame 5 is in the loose state, the angle of the mounting seat 6 can be adjusted to achieve the effect of adjusting the monitoring angle of the camera. When the camera is adjusted to a suitable monitoring angle, the locking screw ring 501 can be tightened again to lock and fix the scissor-type adjustment frame 5, ensuring the stability of its adjustment state.

[0034] Secondly, when the monitoring direction of the camera needs to be adjusted, the connecting plate 3 can be manually rotated to control the scissor-type adjustment frame 5 to rotate and drive the camera to adjust the monitoring direction. Since the connecting plate 3 and the fixed base 1 are connected by a rubber ring 301, the expansion characteristics of the rubber ring 301 facilitate the movement of the connecting plate 3 while ensuring the stability of the connection between it and the fixed base 1.

[0035] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
