Description

A mobile support device for coal mine equipment maintenance Technical Field

[0001] This utility model relates to the field of coal mine equipment maintenance technology, and in particular to a mobile support device for coal mine equipment maintenance. Background Technology

[0002] During the maintenance of coal mine equipment, it is necessary to move the equipment from its original location and support it securely to facilitate detailed inspection of its various parts, troubleshooting, and replacement of parts. The underground surface conditions of coal mines are extremely complex, with a large number of uneven, pitted, and protruding areas caused by mining activities, as well as varying degrees of slope changes.

[0003] Existing movable support devices, such as some simple brackets, may cause the equipment to sway after being lifted from a certain height above the ground due to uneven ground or bumps and vibrations during transportation. This swaying will further aggravate the instability of the center of gravity, especially for some irregularly shaped coal mining equipment with a high center of gravity, which is more likely to tip over during the swaying process.

[0004] Based on the above situation, it is necessary to design a mobile support device for coal mine equipment maintenance to solve the above problems. Summary of the Invention

[0005] This invention provides a mobile support device for the maintenance of coal mine equipment, in order to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A mobile support device for coal mine equipment maintenance includes a mobile vehicle. A support member is movably connected to the mobile vehicle via a hinged frame. A support plate for supporting the coal mine equipment is slidably connected to the support member. A first lifting member for driving the support member to move the coal mine equipment up and down is connected between the bottom of the support plate and the support member. The mobile vehicle is equipped with a flipping mechanism for flipping the support member between a horizontal and a vertical state. When the support member is in a vertical state, the first lifting member can drive the support plate to move upward, thereby lifting the coal mine equipment. When the support member is flipped to a horizontal state by the flipping mechanism, the lifted coal mine equipment is placed in a horizontal position, so that the center of gravity of the equipment is lowered compared to the vertical state.

[0008] Preferably, the flipping mechanism includes a second lifting member, the fixed end of which is hinged to the moving vehicle, and the telescopic end of which is hinged to the supporting member.

[0009] Preferably, the support member has two opposing clamping plates slidably connected via a sliding cavity. A bidirectional screw is rotatably connected inside the sliding cavity. The bidirectional screw passes through the two clamping plates and is threadedly connected to the two clamping plates. A drive motor with its output end connected to one end of the bidirectional screw is provided on one side of the support member.

[0010] Preferably, the clamping plate is connected to an auxiliary clamping member via a first telescopic member.

[0011] Preferably, the end of the mobile vehicle away from the support is provided with a counterweight.

[0012] Preferably, the counterweight is provided with a second telescopic component, and the movable end of the second telescopic component is connected to a push plate.

[0013] The beneficial effects of this utility model are as follows: when the support is in a vertical position, the up-and-down movement of the first lifting member can cause the support plate to move the coal mining equipment up and down, so that the equipment can be removed from the installation position. Then, the flipping mechanism drives the support and the coal mining equipment supported on the support to flip to a horizontal position, thereby lowering the center of gravity of the equipment and improving the stability of the equipment during the movement process when the mobile vehicle moves and transports the coal mining equipment.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Referring to Figures 1-4, a mobile support device for coal mine equipment maintenance includes a mobile vehicle 1. The bottom of the mobile vehicle 1 may be equipped with wheels or the like to facilitate its movement. A support member 3 is movably connected to the mobile vehicle 1 via a hinge frame 2. A support plate 4 for supporting the coal mine equipment is slidably connected to the support member 3. A first lifting member 5 for driving the support member 3 to move the coal mine equipment up and down is connected between the bottom of the support plate 4 and the support member 3. The mobile vehicle 1 is provided with a flipping mechanism for flipping the support member 3 between a horizontal and a vertical state. When the support member 3 is in a vertical state, the first lifting member 5 can drive the support plate 4 to move upward, thereby lifting the coal mine equipment. When the support member 3 is flipped to a horizontal state by the flipping mechanism, the lifted coal mine equipment is placed in a horizontal position, which lowers the center of gravity of the equipment compared to the vertical state.

[0022] Specifically, during use, when the tilting mechanism causes the support member 3 to be in a vertical position, the moving cart 1 moves the support plate 4 close to the bottom of the equipment installed at a certain height, allowing the end of the support plate 4 to be inserted into the bottom of the equipment. When the support member 3 contacts the side wall of the equipment, the first lifting member 5 moves the support plate 4 upwards to lift the equipment. Then, the moving cart 1 can move backwards, and the first lifting member 5 moves the support plate 4 downwards, lowering the height of the lifted equipment. Then, under the action of the tilting mechanism, the support member 3 slowly tilts in the opposite direction until it is tilted to a horizontal position. At this point, the center of gravity of the equipment is lowered to its lowest point, resulting in better stability when the moving cart 1 moves the equipment for transport.

[0023] The flipping mechanism includes a second lifting member 6. The fixed end of the second lifting member 6 is hinged to the mobile vehicle 1, and the telescopic end of the second lifting member 6 is hinged to the support member 3. When the second lifting member 6 performs telescopic movements, it changes the connection length and angle relationship between itself, the support member 3, and the mobile vehicle 1. Since the support member 3 is movably connected to the mobile vehicle 1 through the hinge frame 2, this change in length and angle will generate a torque that causes the support member 3 to rotate around the hinge frame 2, thereby driving the support member 3 to flip between the horizontal and vertical states. When the second lifting member 6 extends, its telescopic end pushes the support member 3. Because the support member 3 and the moving vehicle 1 are connected by the articulated frame 2 to form a rotating pair, under the thrust of the second lifting member 6, the support member 3 will rotate upward around the articulated frame 2, gradually changing from a horizontal state to a vertical state. When the second lifting member 6 retracts, the telescopic end pulls the support member 3, causing the support member 3 to rotate downward around the articulated frame 2, returning from a vertical state to a horizontal state. Both the second lifting member 6 and the first lifting member 5 can be driven by hydraulic cylinders or other devices that can provide a large torque.

[0024] Referring to Figure 4, furthermore, to improve the stability of the equipment when supporting it on the support plate 4, two opposing clamping plates 8 are slidably connected to the support member 3 via a sliding cavity 7. A bidirectional screw 9 is rotatably connected inside the sliding cavity 7, passing through the two clamping plates 8 and threadedly connected to them. A drive motor 10 with its output end connected to one end of the bidirectional screw 9 is provided on one side of the support member 3. The drive motor 10 drives the bidirectional screw 9 to rotate, and under the limiting sliding action of the sliding cavity 7 on the clamping plates 8, the two clamping plates 8 move in opposite or relative directions, thereby achieving the clamping or releasing of the equipment on the support plate 4.

[0025] Among them, the clamping plate 8 is connected to the auxiliary clamping member 12 through the first telescopic member 11. When the distance between the two clamping plates 8 is the smallest, the first telescopic member 11 drives the movement of the auxiliary clamping member 12 to clamp the equipment, so as to clamp and limit some small equipment. In addition, multiple sets of bidirectional screws can be provided on the support member 3 along the length extension direction of the support member 3 to clamp the equipment from different height positions, and the limiting effect is better.

[0026] Referring to Figure 1, furthermore, a counterweight 13 is provided at the end of the mobile vehicle 1 away from the support member 3. When the support member 3 lifts the coal mining equipment, the weight of the equipment will cause the front end of the mobile vehicle 1 to bear a large pressure. If it is not balanced, the mobile vehicle 1 may tend to tilt forward, especially when the ground is uneven or when the equipment is being overturned. This risk of tilting forward will be further increased. By setting a counterweight 13 at the end of the mobile vehicle 1 away from the support member 3, a reverse torque can be generated to balance the tilting torque brought about by supporting the equipment, so that the mobile vehicle 1 remains stable during the process of carrying the equipment and reduces the possibility of overturning due to imbalance of the center of gravity.

[0027] Referring to Figure 1, the counterweight 13 is further provided with a second telescopic member 14. The movable end of the second telescopic member 14 is connected to a push plate 15. Both the second telescopic member 14 and the first telescopic member 11 can be devices capable of reciprocating linear motion, such as electric telescopic rods or electric push rods. When the support member 3 is in a horizontal state and drives the center of gravity of the equipment to be lowered, the second telescopic member 14 drives the push plate 15 to abut against the end of the equipment, thereby cooperating with the support plate 4 and the clamping plate 8 to clamp the equipment on multiple sides, thereby fixing the equipment. The stability effect is better when the mobile vehicle 1 drives the equipment to move.
