[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0035] like Figures 1-5As shown, a lifting device for easy fixing during the maintenance of electromechanical equipment in open-pit coal mines includes a lifting device body consisting of a base 1, fixed columns 2, a top seat 3, and an electric hoist 4. There are two bases 1 and two fixed columns 2, each vertically mounted on the top of one base 1. The tops of the two fixed columns 2 are connected to the two sides of the bottom of the top seat 3. The electric hoist 4 is located in the middle of the bottom of the top seat 3. The bottom of the base 1 is equipped with casters 5. A mounting base 6 is provided on each fixed column 2. A first motor 7 is installed inside the mounting base 6. The first motor 7 is connected to a first screw 10 via a coupling. The first screw 10 is located in a lifting chamber 8. A lifting seat 11 is provided on the first screw 10, and the lifting seat 11 is connected to a first connecting... The connecting rod 12 is connected to the fixed base 13. Several ground nails 14 are installed at the bottom of the fixed base 13 to be embedded in the soil and improve the stability of the device when stationary. A second motor 15 is installed inside the top seat 3, and the output end of the second motor 15 is connected to the second screw 18 via a coupling. A movable seat 19 is installed on the second screw 18, and the movable seat 19 is connected to the clamping seat 21 via a second connecting rod 20 for clamping and fixing the coal mine electromechanical equipment. This invention not only fixes the position of the hoisting device body in a stationary state after the ground nails 14 are inserted into the soil, improving the stability during use, but also, the clamping plates can clamp and fix the coal mine electromechanical equipment after the hoisting operation is completed, effectively preventing it from easily collapsing due to inertia. This causes shaking, affecting equipment stability and posing a potential safety threat to operators. The base 1 has casters 5 at both the front and rear ends, each with a brake block. The casters 5 facilitate the displacement of the lifting device body, while the brake blocks restrict movement after reaching the designated location, thus completing the initial positioning of the lifting device body. The mounting base 6 is vertically located outside the lower end of the fixed column 2. The mounting base 6 is inverted T-shaped, with a lifting cavity 8 at its upper interior. The first screw 10 is vertically located within the lifting cavity 8, and its outer thread matches the inner thread of the lifting base 11. The first motor 7... When the first screw 10 is started and rotated, the lifting seat 11 rotates along with the first screw 10, moving up and down within the lifting chamber 8. The lower end of the mounting seat 6 is a receiving groove 9 for accommodating the fixed seat 13 and the ground nail 14. The top end of the first connecting rod 12 is connected to the bottom end of the lifting seat 11, and the bottom end of the first connecting rod 12 passes through the lifting chamber 8 and is connected to the top end of the fixed seat 13. When the lifting seat 11 moves up and down, the fixed seat 13 and the ground nail 14 can be driven to move up and down synchronously via the first connecting rod 12. When the fixed seat 13 rises into the receiving groove 9, it can accommodate the ground nail 14. Conversely, when the fixed seat 13 descends to the ground, the ground nail 14 is submerged in the soil. This further limits the position of the lifting device body and increases its stability during use.The top seat 3 has a movable cavity 16 inside, and movable grooves 17 are formed on both sides of its bottom end, and the movable grooves 17 are connected to the movable cavity 16. The second screw 18 is horizontally located in the movable cavity 16. When the second motor 15 is started, it can drive the second screw 18 to rotate. The second screw 18 is a screw with both positive and negative threads. Movable seats 19 are provided on both sides of the second screw 18, and the inner threads of the two movable seats 19 are respectively adapted to the outer threads of the two sides of the second screw 18. Because the second screw 18 is a screw with both positive and negative threads, when the second screw 18 rotates, the two movable seats 19 can rotate with the second screw 18, moving close to or opposite to each other in the movable cavity 16. The top end of the second connecting rod 20 passes through the movable groove 17 and the bottom of the movable seat 19. The first end is connected to the second connecting rod 20, while the bottom end of the second connecting rod 20 is connected to the outside of the clamp 21. When the two moving seats 19 move close together or in opposite directions, they can drive the clamps 21 on both sides to move synchronously via the second connecting rod 20 connected to them. When the two clamps 21 move relative to each other, they can clamp and fix the coal mine electromechanical equipment; conversely, they can release the clamping and fixing state of the coal mine electromechanical equipment. The inner side of the clamp 21 is provided with an anti-slip rubber pad 22. Through the establishment of the anti-slip rubber pad 22 on the inner side of the clamp 21, during the clamping and fixing process of the coal mine electromechanical equipment, the anti-slip rubber pad 22 is in close contact with the outer wall of the coal mine electromechanical equipment, which can not only increase the friction coefficient and enhance the stability of clamping and fixing, but also protect the outer wall of the coal mine electromechanical equipment and prevent wear.
[0036] The working principle of this utility model is as follows: After the lifting device body is moved to the designated location via the moving wheels 5, the movement ability of the moving wheels 5 is restricted by the brake blocks to initially fix the device. Then, the first motor 7 is started to drive the first screw 10 to rotate, causing the lifting seat 11 to rotate along with the first screw 10. The first connecting rod 12 drives the fixing seat 13, on which the ground nail 14 is installed, to move downwards, so that the ground nail 14 is embedded in the soil, thereby further fixing the device and effectively improving the stability during use. When the electric hoist 4 lifts the coal mine electromechanical equipment, only the second motor 15 needs to be started, and the second motor 15 can drive the second screw 18 to rotate. Since the second screw 18 is a positive and negative thread screw... When the second screw 18 rotates, the movable seats 19 on both sides can rotate with the second screw 18 and move close to or opposite to each other in the movable cavity 16. When the movable seats 19 on both sides move close to or opposite to each other, they can drive the clamping seats 21 on both sides to move synchronously through the second connecting rod 20 connected to them. After the clamping seats 21 on both sides move relative to each other, they clamp and fix the coal mine electromechanical equipment. Through the establishment of the anti-slip rubber pad 22 on the inner side of the clamping seat 21, during the clamping and fixing process of the coal mine electromechanical equipment, the anti-slip rubber pad 22 is in close contact with the outer wall of the coal mine electromechanical equipment, which can increase the friction coefficient, enhance the stability of clamping and fixing, and protect the outer wall of the coal mine electromechanical equipment to prevent wear.
