DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a hydraulic self-supporting two-speed multi-purpose winch embodiment.

[0024] A hydraulic self-supporting two-speed multi-purpose winch comprises a two-speed winch 1. A hydraulic support mechanism 2 is arranged on the two-speed winch 1. The hydraulic support mechanism 2 comprises a plurality of mounting frames 3 symmetrically and fixedly mounted on both sides of the two-speed winch 1. A support frame 4 is mounted on the mounting frame 3. A first leg 5 is fixedly mounted on the support frame 4. A second leg 6 is slidably mounted inside the first leg 5. A hydraulic cylinder 7 is movably mounted on the bottom of the support frame 4. One end of the hydraulic cylinder 7 is movably connected to the second leg 6. By setting the hydraulic support mechanism 2, the two-speed winch 1 can be stably placed on the coal mining working surface. When the two-speed winch 1 is placed on the coal mining working surface and tilted, the hydraulic cylinder 7 in the tilted position is started to extend its output end to push the second leg 6, so that the second leg 6 extends from the first leg 5 to extend the support height to lift the tilted part of the two-speed winch 1 so that it no longer tilts. The second legs 6 around the two-speed winch 1 are adjusted by the hydraulic cylinder 7 to keep the two-speed winch 1 able to be placed on the coal mining working surface in a balanced and stable manner to prevent affecting the normal use of the two-speed winch 1.

[0025] A plurality of fixed anchor rods 8 are installed on the second leg 6, and the bottom of the fixed anchor rods 8 is set to be conical, and a plurality of reinforcing ribs 9 are fixedly installed inside the support frame 4, and the plurality of reinforcing ribs 9 are cross-distributed, and the mounting frame 3 and the support frame 4 are movably connected, and a fixed frame 10 is installed above the mounting frame 3, and a screw rod 11 is movably installed inside the fixed frame 10, and a motor 12 connected to the screw rod 11 is fixedly installed on one side of the fixed frame 10, and a moving block 13 connected by a thread is arranged on the screw rod 11, and a telescopic rod 14 is installed at one end of the moving block 13, and a bearing 15 movably connected to the telescopic rod 14 is installed on the top of the support frame 4. By setting a plurality of fixed anchor rods 8 and setting their bottoms to be conical, the second leg 6 can drill and insert the plurality of fixed anchor rods 8 into the ground when contacting the ground for support, so that the contact between the second leg 6 and the ground is more stable, avoiding movement during use. The structural strength of the support frame 4 is improved by setting the reinforcing ribs 9. By setting the fixed frame 10, the screw rod 11, the motor 12, the moving block 13, the telescopic rod 14 and the bearing 15, the motor 12 is started to drive the screw rod 11 to rotate. The rotation of the screw 11 pulls the telescopic rod 14 through the moving block 13, so that the telescopic rod 14 pulls the support frame 4 through the bearing 15, thereby playing the function of adjusting the support angle of the support frame 4, so that it can better adapt to the terrain of the coal mining working face for support.

[0026] A fixed box 16 is provided on the driving machine of the two-speed winch 1, a heat dissipation fan 17 is provided on the top of the fixed box 16, a heat dissipation port 18 is provided on one side of the fixed box 16, and the heat dissipation fan 17 is fixedly connected to the fixed box 16 by a plurality of bolts 19. By setting the fixed box 16, the heat dissipation fan 17 and the heat dissipation port 18, starting the heat dissipation fan 17 to supply air to the motor on the two-speed winch 1 can speed up the heat dissipation rate of the motor, making it run more stably, and the heat can be discharged outward through the heat dissipation port 18, and bolts 19 are used to install the heat dissipation fan 17 on the fixed box 16, so that the heat dissipation fan 17 can be removed from the fixed box 16, which is convenient for replacement when it is damaged.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a hydraulic self-supporting dual-speed multi-purpose winch provided in this embodiment is as follows:

[0028] When the two-speed winch 1 is placed on the coal mining working surface and tilted, the hydraulic cylinder 7 in the tilted position is started to extend its output end to push the second leg 6, so that the second leg 6 extends from the first leg 5 to extend the support height to lift the tilted part of the two-speed winch 1 so that it no longer tilts. The second legs 6 around the two-speed winch 1 are adjusted by the hydraulic cylinder 7 to keep the two-speed winch 1 able to be placed on the coal mining working surface in a balanced and stable manner. The motor 12 is started to drive the screw 11 to rotate. The rotation of the screw 11 pulls the telescopic rod 14 through the moving block 13, so that the telescopic rod 14 pulls the support frame 4 through the bearing 15, thereby adjusting the support angle of the support frame 4 so that it can better adapt to the terrain of the coal mining working surface for support. Starting the cooling fan 17 to supply air to the motor on the two-speed winch 1 can accelerate the heat dissipation rate of the motor, make it run more stably, and the heat can be discharged outward through the heat dissipation port 18.

[0029] In summary, in this embodiment, according to a hydraulic self-supporting dual-speed multi-purpose winch of this embodiment, by setting a plurality of fixed anchor rods 8 and setting the bottom thereof to a cone, the second leg 6 drills and inserts the plurality of fixed anchor rods 8 into the ground when supporting in contact with the ground, so that the contact between the second leg 6 and the ground is more stable, and movement during use is avoided. The structural strength of the support frame 4 is improved by setting the reinforcing ribs 9. By setting the fixed frame 10, the screw rod 11, the motor 12, the moving block 13, the telescopic rod 14 and the bearing 15, the motor 12 is started to drive the screw rod 11 to rotate, and the rotation of the screw rod 11 is then adjusted by the moving block 13. The telescopic rod 14 is pulled, so that the telescopic rod 14 pulls the support frame 4 through the bearing 15, thereby adjusting the support angle of the support frame 4 so that it can better adapt to the terrain of the coal mining face for support. By setting the fixed box 16, the cooling fan 17 and the cooling port 18, starting the cooling fan 17 to supply air to the motor on the dual-speed winch 1 can speed up the heat dissipation rate of the motor and make it run more stably. The heat can be discharged to the outside through the cooling port 18, and the cooling fan 17 is installed on the fixed box 16 by bolts 19, so that the cooling fan 17 can be removed from the fixed box 16, which is convenient for replacement when it is damaged.

[0030] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
