Technical Field
[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hoisting equipment for coal mine electromechanical transportation. Background Art
[0002] During the coal mining process, it is often necessary to transport, install and remove coal mine electromechanical equipment underground, and almost all of these need to be completed with the help of hoisting equipment. However, the height of the underground roadway is relatively low, and large hoisting equipment cannot be used. Therefore, people usually use the crossbeam on the roadway or special hoisting bolts as the rooting points. Whether using the crossbeam or the bolts, a large amount of time is required to prepare the hoisting area in advance, resulting in low efficiency.
[0003] Moreover, the boom structure of small hoisting machines in the prior art is simple and lacks corresponding support, so the stability during hoisting operations is relatively poor. It often causes the electromechanical equipment to collide with the inner wall of the coal mine during transportation. Moreover, after a long period of continuous hoisting operations, the boom is likely to bend, and the safety cannot be guaranteed. Summary of the Utility Model

During the hoisting process of coal mine electromechanical equipment, the triangular support mechanism will assist in supporting the boom of the workpiece hoisting mechanism, which can not only prevent the boom from being bent, but also improve the safety of hoisting operations. The workpiece hoisting mechanism includes an inclined boom movably installed on the installation turntable, a hoisting assembly and a rope-pressing rotating shaft are arranged on the inclined boom, a guiding roller is movably installed at the top of the inclined boom, and a driving motor for changing the pitching angle of the inclined boom is fixedly installed on the installation turntable. When the driving motor is energized and operates, it will cause the inclined boom to rotate upward or downward, thereby adjusting the pitching angle of the inclined boom. The triangular support mechanism includes a fixed convex block fixedly installed on the side of the inclined boom, a sliding bracket is movably installed on the inclined boom, a rectangular chute and a circular through-hole are formed through the side of the sliding bracket. Initially, the fixed convex block is located inside the rectangular chute. When the staff pushes the sliding bracket upward, the fixed convex block will move into the circular through-hole.
[0006] Preferably, the lifting assembly includes a winding drum movably installed on the inclined boom. A steel wire rope is fixedly connected to the winding drum. A lifting motor for driving the winding drum is fixedly installed on the inclined boom. When the lifting motor is powered on, it will drive the winding drum to rotate, thereby completing the winding and releasing of the steel wire rope.
[0007] Preferably, one end of the steel wire rope is fixedly connected to the winding drum, and the other end of the steel wire rope passes through the lower end of the rope pressing rotating shaft and bypasses the guiding roller. A workpiece hanging basket is fixedly installed at the end of the steel wire rope. During the process of the winding drum winding the steel wire rope, the workpiece hanging basket will move vertically upward.
[0008] Preferably, the circular through groove communicates with the rectangular sliding groove, and the inner diameter of the circular through groove matches the size of the fixed convex block.

[0010] Preferably, the side wall of the sliding bracket is extensible. When the height of the inclined boom is relatively high, the staff can stretch the sliding bracket to make it contact the ground.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] In the prior art, the lifting arm structure of the lifting equipment is simple, and the stability during the lifting operation is relatively poor, often resulting in the collision between the electromechanical equipment and the inner wall of the coal mine shaft during transportation. To solve this technical defect in the prior art, as Figures 1-4 shown, this embodiment proposes a lifting equipment for coal mine electromechanical transportation, which can automatically perform triangular support on the inclined lifting arm 301 during the lifting process, which can not only effectively prevent the inclined lifting arm 301 from being bent by heavy objects, but also significantly improve the stability of the equipment during the lifting operation. An installation turntable 2 with adjustable angle is provided on the mine flatbed truck 1, a workpiece lifting mechanism 3 for lifting coal mine electromechanical is provided on the installation turntable 2, and a triangular support mechanism 4 for supporting the lifting arm to improve the lifting stability is provided on the workpiece lifting mechanism 3. During the lifting process of the coal mine electromechanical, the triangular support mechanism 4 will assist in supporting the lifting arm of the workpiece lifting mechanism 3, which can not only avoid the lifting arm from being bent, but also improve the safety of the lifting operation.
[0023] In order to improve the adaptability of the device in various environments, a workpiece lifting mechanism 3 is provided in this embodiment. Specifically, the workpiece lifting mechanism 3 includes an inclined boom 301 movably installed on the mounting turntable 2. An lifting assembly 302 and a rope pressing rotating shaft 303 are arranged on the inclined boom 301. A guiding roller 304 is movably installed at the top end of the inclined boom 301. A driving motor 306 for changing the pitching angle of the inclined boom 301 is fixedly installed on the mounting turntable 2. When the driving motor 306 is energized and operates, it will cause the inclined boom 301 to rotate upward or downward, thereby adjusting the pitching angle of the inclined boom 301. The lifting assembly 302 includes a winding drum movably installed on the inclined boom 301. A steel wire rope is fixedly connected to the winding drum. A lifting motor 307 for driving the winding drum is fixedly installed on the inclined boom 301. When the lifting motor 307 is energized, it will drive the winding drum to rotate, thereby completing the winding and release of the steel wire rope. One end of the steel wire rope is fixedly connected to the winding drum, and the other end of the steel wire rope passes through the lower end of the rope pressing rotating shaft 303 and bypasses the guiding roller 304. A workpiece hanging basket 305 is fixedly installed at the end of the steel wire rope. During the process of the winding drum winding the steel wire rope, the workpiece hanging basket 305 will move vertically upward.
[0024] In order to prevent the inclined boom 301 from being bent and improve the stability during hoisting operations, a triangular support mechanism 4 is provided in this embodiment. Specifically, the triangular support mechanism 4 includes a fixed convex block 401 fixedly installed on the side surface of the inclined boom 301. A sliding bracket 402 is movably installed on the inclined boom 301. The side wall of the sliding bracket 402 can be extended. When the height of the inclined boom 301 is relatively high, the staff can stretch the sliding bracket 402 to make it contact the ground. A rectangular sliding groove 403 and a circular through groove 404 are formed through the side surface of the sliding bracket 402. Initially, the fixed convex block 401 is located inside the rectangular sliding groove 403. When the staff pushes the sliding bracket 402 upward, it will cause the fixed convex block 401 to move into the circular through groove 404. The circular through groove 404 is communicated with the rectangular sliding groove 403. The inner diameter of the circular through groove 404 matches the size of the fixed convex block 401. After the fixed convex block 401 enters the circular through groove 404, the sliding bracket 402 can rotate freely. An anti-slip rubber block 405 is detachably installed on the sliding bracket 402. When the sliding bracket 402 rotates downward, the anti-slip rubber block 405 will contact the ground, thereby increasing the friction between the sliding bracket 402 and the ground and improving the stability.
[0025] In this embodiment, when the staff uses this hoisting device to hoist coal mine electromechanical equipment, they will first use the mounting turntable 2 to adjust the position of the inclined boom 301, and then use the driving motor 306 to adjust the pitching angle of the inclined boom 301 until the workpiece hanging basket 305 is located above the mine shaft.
[0026] Next, the staff will hold a long rod and push the sliding bracket 402 obliquely upward from the side of the inclined boom 301. When the fixed bump 401 moves from the rectangular chute 403 to the inside of the circular through-hole 404, the sliding bracket 402 will rotate downward under the action of gravity. Subsequently, the anti-slip rubber block 405 on the sliding bracket 402 will contact the ground, as Figure 3 shown, so as to assist in supporting the inclined boom 301.
[0027] Subsequently, the staff will use the lifting assembly 302 and the workpiece hanging basket 305 to transport and install the coal mine electromechanical equipment. After the hoisting is completed, the staff will use the long rod to make the sliding bracket 402 rotate upward until the fixed bump 401 is parallel to the rectangular chute 403. Next, the sliding bracket 402 will slide downward along the fixed bump 401 to reset.
[0028] In this embodiment, by setting up the workpiece lifting mechanism 3 and using the mutual cooperation between the lifting assembly 302 and the installation turntable 2, the position and pitching angle of the inclined boom 301 can be automatically adjusted, greatly improving the applicability of the hoisting equipment. Moreover, by using the pressing rope rotating shaft 303 to limit and press the steel wire rope, the steel wire rope is parallel to the inclined boom 301, which can effectively prevent the derailment between the steel wire rope and the guiding roller 304. In addition, in this embodiment, by setting up the triangular support mechanism 4 and using the mutual cooperation between the sliding bracket 402 and the fixed bump 401, the inclined boom 301 can be automatically supported in a triangular shape during the hoisting process, which can not only effectively prevent the inclined boom 301 from being bent by heavy objects, but also significantly improve the stability of the equipment during the hoisting operation, thus ensuring the safety of the hoisting operation.

The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model mainly aims to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
