Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a safety monitoring system for a coal mine machine repair center. Background Art

[0002] In modern coal mine production, production safety has become a vital issue. As the core area for mine machinery maintenance and repair, the coal mine machine repair center has a complex and changeable operating environment, which not only involves the frequent operation of a large number of heavy machinery, but also includes the intensive use of various maintenance tools and materials, coupled with potential harmful gases and dust, making this area a key focus of coal mine safety management. In order to effectively monitor the behavioral norms of operators and ensure the compliance and safety of the work site, it is particularly important to implement scientific and reasonable monitoring measures.

[0003] Traditional monitoring systems are often limited to fixed installation locations and are difficult to fully cover all operating areas, especially in machine repair centers with open spaces and complex structures. The problem of blind spots in monitoring is particularly prominent, and manual inspections and static monitoring alone can no longer meet regulatory needs. How to innovatively utilize existing facilities and combine advanced monitoring technology to achieve full-scale monitoring of coal mine machine repair centers has become an urgent problem to be solved.

[0004] The existing patent authorization number is CN206927485U, which is a double-beam electric hoist trolley, including a chassis, a travel gear, a rotating shaft, a travel motor, a mounting frame, a high-definition camera, a trolley body, a reel, a high-power rotating motor, a wire rope, a hook, a pressure sensor, a power supply, a display, a relay, a red light, a yellow light, and a green light. Travel gears are installed on the left and right sides of the chassis respectively. Two high-definition cameras are installed on the chassis of the double-beam electric hoist trolley, which can monitor the electric hoist trolley in real time while it is traveling.

[0005] The applicant has found that the prior art mainly focuses on the operation monitoring of the crane itself, while neglecting the real-time monitoring of the surrounding operating environment by utilizing the characteristics of the existing reciprocating movement of the crane. Utility Model Content

[0006] The utility model aims to provide a safety monitoring system for a coal mine machine repair center to solve the technical problem of poor static monitoring effect existing in the prior art.

[0007] In order to solve the above problems, a coal mine machine repair center safety monitoring system involved in the utility model adopts the following technical solutions:

[0008] The utility model provides a safety monitoring system for a coal mine machine repair center, which includes a crane, a frame and a camera.

The column is arranged between the crossbeam and the longitudinal beam seat. The column is vertically matched and connected to the crossbeam, the column is vertically matched and connected to the longitudinal beam seat, the crossbeam is connected to the bottom of the crane, and the camera is installed at the bottom of the longitudinal beam seat.

[0009] Preferably, the cross beam is perpendicular to the longitudinal beam seat, and the vertical projections of the cameras are all located on the longitudinal beam seat.

[0016] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The utility model provides a safety monitoring system for a coal mine machine repair center, comprising a crane 1, a frame 6 and a camera 5. The crane 1 is an existing device used to move along a track and has an electric hoist thereon for transporting the device within the site. The frame 6 provides a hanging platform for the camera 5. The device installs the camera 5 under the crane 1 through the frame 6. Due to its height and mobility, the crane 1 can provide the camera 5 with a high-angle and wide-range monitoring field of view, covering the entire or most of the indoor operating area, and can observe the operator's behavior and operation more comprehensively and without blind spots than the camera 5 fixed on the ground. In addition, the characteristic of the crane 1 moving with the track enables the monitoring range of the camera 5 to change with the movement of the crane 1, dynamically adjust the monitoring key area or follow the specific operation process for monitoring, and at the same time utilize the existing resources to improve the flexibility and practicality of the monitoring system.

[0018] The frame 6 includes a crossbeam 2, a longitudinal beam seat 3, and a column 4. The column 4 is arranged between the crossbeam 2 and the longitudinal beam seat 3. The column 4 is vertically matched and connected to the crossbeam 2. The column 4 is vertically matched and connected to the longitudinal beam seat 3. The crossbeam 2 is connected to the bottom of the vehicle 1. The camera 5 is installed at the bottom of the longitudinal beam seat 3. The crossbeam 2 is perpendicular to the longitudinal beam seat 3. The vertical projection of the camera 5 is located on the longitudinal beam seat 3. The device adopts a crossbeam and longitudinal double beam structure, which can significantly improve the torsional rigidity and vibration absorption capacity of the structure, thereby reducing resonance, attenuating the vibration transmitted to the camera 5 when the vehicle 1 moves, reducing picture jitter, and ensuring the quality of the monitoring video.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
