[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] Reference Figure 1-5, a collision prevention protection device for electromechanical equipment in underground coal mines, including a support frame 1, with legs fixedly installed at the four corners of the bottom of the support frame 1, which can provide support for the support frame 1, and a limit assembly 1 for fixing the electromechanical equipment in the support frame 1 is provided on the support frame 1, and the limit assembly 1 includes multiple screw rods 11, multiple abutment plates 12 and multiple adjusting wheels. Multiple screw rods 11 are threadedly installed on the support frame 1, and abutment plates 12 are rotatably installed on the multiple screw rods 11. One end of the screw rod 11 away from the abutment plate 12 extends to the outside of the support frame 1 and is fixedly sleeved with an adjusting wheel. Rotating the adjusting wheel can drive the screw rod 11 to move horizontally on the support frame 1, thereby driving the abutment plate 12 to move and abut against the electromechanical equipment to achieve fixation and limitation of the electromechanical equipment.

[0024] Both sides of the top of the support frame 1 are provided with side anti-collision plates 2 installed in a hinged state, and the top side of the side anti-collision plate 2 is connected to the top anti-collision plate 21 in a hinged manner. The side anti-collision plates 2 and the top anti-collision plate 21 cooperate with each other to protect the left and right sides and top of the electromechanical equipment. The top side of the top anti-collision plate 21 is provided with a strip plate 24 for providing support for the two support plates 23, and the bottom side of the strip plate 24 is provided with a transmission assembly. The transmission assembly includes a gear 25 fixedly sleeved on the corresponding rotating shaft 22 and arranged in a mutually meshing state. The side of the two side anti-collision plates 2 close to each other is fixedly installed with a rotating shaft 22 that is rotatably connected to the two support plates 23. A limiting assembly 2 is provided on the rotating shaft 22 on the left side. The limiting assembly 2 includes a limiting slide bar 32, a limiting wheel 3 and a plurality of support blocks 31. The strip plate 24 The four corners of the bottom side are fixedly installed with support blocks 31, and a damping slide bar 32 is installed on the support block 31 located on the left front for damping sliding. The front end of the rotating shaft 22 located on the left side is fixedly sleeved with a limiting wheel 3, and a plurality of limiting grooves are provided on the outer peripheral surface of the limiting wheel 3, and the limiting slide bar 32 is adapted to the limiting groove. When one of the side anti-collision plates 2 is collided, under the action of the transmission component, the two side anti-collision plates 2 can be rotated in opposite directions respectively, so that the other side anti-collision plate 2 and the collided side anti-collision plate 2 move in opposite directions and achieve better buffering, effectively improving the protection effect. At the same time, the limiting component 2 set up can limit the rotating shaft 22 as needed, so that the anti-collision protection device can be adjusted to hard protection and soft protection states as needed, so that it can adapt to different usage scenarios.

[0025] A collision buffer assembly is also provided on the bottom side of the strip plate 24, and the collision buffer assembly includes a semi-rigid support plate 4, multiple damping springs 41 and multiple damping rods 42. The same semi-rigid support plate 4 is fixedly installed on the side where the two side anti-collision plates 2 are close to each other. The semi-rigid support plate 4 is made of a steel plate with a certain toughness, so that it can provide support while being able to elastically deform with the deflection of the side anti-collision plate 2. The top side of the semi-rigid support plate 4 is fixedly installed with multiple damping springs 41 and multiple damping rods 42. The top ends of the multiple damping rods 42 are respectively fixedly connected to the corresponding support plates 23, and the top ends of the multiple damping springs 41 are all fixedly connected to the bottom side of the strip plate 24, which can provide effective buffering when the side anti-collision plates 2 are collided, thereby avoiding the collision force directly acting on the electromechanical equipment that needs protection.

[0026] The side anti-collision plate 2 is provided with a plurality of strip-shaped openings, in which an L-shaped baffle 5 is installed in a damping sliding manner, and a handle is fixedly installed on the L-shaped baffle 5, which is convenient for disassembly and assembly of the L-shaped baffle 5. The L-shaped baffle 5 can also provide shielding protection for the front and rear sides of the electromechanical equipment and achieve anti-collision effect. At the same time, it is also convenient for quick disassembly and assembly of the L-shaped baffle 5, and it is convenient for the side anti-collision plate 2 to have a certain ventilation function after the L-shaped baffle 5 is removed without affecting the anti-collision effect of the two side anti-collision plates 2, thereby improving the practicality of the anti-collision protection device.

[0027] In this embodiment, legs are fixedly mounted at the four corners of the bottom of the support frame 1 to provide support for the support frame 1 .

[0028] In this embodiment, a handle is fixedly mounted on the L-shaped baffle 5 for facilitating the assembly and disassembly operations of the L-shaped baffle 5 .

[0029] Working principle: When in use, first place the electromechanical equipment in the support frame 1, and by rotating the adjusting wheel, the screw rod 11 drives the abutment plate 12 to move and abut against the electromechanical equipment, thereby achieving the fixation and limitation of the electromechanical equipment. Then, the L-shaped baffle 5 is inserted into the strip-shaped opening, so that it can provide shielding protection for the front and rear sides of the electromechanical equipment without affecting the deflection of the two side anti-collision plates 2. When one of the side anti-collision plates 2 is collided, the two side anti-collision plates 2 are deflected in opposite directions under the action of the two gears 25 and the two rotating shafts 22. At the same time, the top anti-collision plate 21 will also follow the deflection of the side anti-collision plate 2 to achieve corresponding deflection, thereby achieving all-round protection of the electromechanical equipment. At this time, the damping spring 41 and the damping rod 42 in the collision buffer assembly and the semi-rigid support plate 4 can provide effective buffering to reduce the impact of the collision on the electromechanical equipment. In addition, through the cooperation of the set limit slide 32 and the limit wheel 3 and the multiple limit slots opened on the limit wheel 3, the anti-collision protection device can be adjusted to the hard protection and soft protection states as needed to adapt to different usage scenarios.

[0030] The above is a detailed introduction to the anti-collision protection device for electromechanical equipment in underground coal mines provided by the present invention. Specific embodiments are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
