[0021] Reference Figures 1 to 10 In an embodiment of the present application, a hoisting device with adjusting function comprises: a support 100, a base 110 connected to the lower end of the support 100; a working part 200, comprising a rotating seat 210 and a working arm 220 connected to the rotating seat 210, the rotating seat 210 being rotationally arranged on the upper end of the support 100, the working arm 220 having a downward tendency of 1 to 5 degrees in the direction away from the rotating seat 210; A motor 300 is coaxially installed in the rotating seat 210, and has a rotating shaft, the upper end of which is connected to a wire wheel 310, and a working switch is arranged corresponding to the motor 300. The sliding seat part 400 includes a roller part 410, a hanging plate 420, a cable hanging part 430 and a linear drive 440. The roller part 410 is fixedly and slidably arranged along the length direction of the working arm 220. The hanging plate 420 is connected to the roller part 410 and extends downward. The linear drive 440 is fixed to the hanging plate 420. The cable hanging part 430 includes a fixed shaft 431 and a first brake plate 432 connected to one end of the fixed shaft 431 along the length direction. The other end of the fixed shaft 431 is connected to the output end of the linear drive 440. The hanging part includes a hanging cable 510 and a hanging part 520. One end of the hanging cable 510 is wound around the wire wheel 310. The other end of the hanging cable 510 extends downward after passing around the fixed shaft 431 and is connected to the hanging part 520. When the linear drive 440 is driven to extend or retract, the first brake plate 432 clamps and releases the hanging cable 510 together with the hanging plate 420.

[0022] In the prior art, the sliding of the working platform on the working arm and the rotation of the working arm on the base are generally realized manually or matched with separate driving mechanisms. Manual sliding and rotation are inconvenient in some cases, and the increase of separate driving mechanisms increases the overall complexity and reduces the hoisting range.

[0023] The lifting device with adjustment function provided by the application has a support 100 as a foundation. The lower end of the support 100 is connected to a base 110. The base 110 can be provided with universal wheels or other devices facilitating transfer.

[0024] The working part 200 includes a rotating seat 210 and a working arm 220 connected to the rotating seat 210. The working arm 220 can be welded or bolted to the rotating seat 210. The rotating seat 210 is rotatably arranged on the upper end of the support 100. A bearing can be arranged between the rotating seat 210 and the support 100 to reduce the resistance of the rotating seat 210. The working arm 220 has a downward inclination of 1 to 5 degrees in the direction away from the rotating seat 210.

[0025] The rotating seat 210 is provided with a mounting cavity, and the motor 300 is coaxially mounted in the mounting cavity of the rotating seat 210. In one structure, the rotating seat 210 is a combined structure in the circumferential direction, so that the rotating seat 210 is convenient to mount on the support column 100, and the mounting of the motor 300 is also smoothly performed. The motor 300 outputs a rotating shaft. The upper end of the rotating shaft penetrates the rotating seat 210 and is connected with the wire wheel 310. A working switch is arranged corresponding to the motor 300, and the working switch is operated to realize the forward rotation, reverse rotation and stop of the motor 300. The communication mode between the working switch and the motor 300 can be wired or wireless.

[0026] The sliding seat part 400 includes a roller part 410, a hanging plate 420, a hanging cable part 430 and a linear drive 440. The roller part 410 is fixedly and slidably arranged in the length direction of the working arm 220. For example, the working arm 220 is provided with a track, and the roller part 410 is hung on the track and can slide on the track. In a free state, the sliding seat part 400 is self-weighted down through the slope of the working arm 220. The hanging plate 420 is connected to the roller part 410 and extends downward. The linear drive 440 is fixed to the hanging plate 420. The linear drive 440 can be pneumatic, hydraulic or motor driven. The hanging cable part 430 includes a fixed shaft 431 and a first brake plate 432 connected to one end of the fixed shaft 431 in the length direction. For example, the first brake plate 432 is in the form of a disc coaxial with the fixed shaft 431. The other end of the fixed shaft 431 is connected to the output end of the linear drive 440. The extension and retraction of the linear drive 440 can drive the hanging cable part 430 to move.

[0027] The hanging part includes a hanging cable 510 and a hanging part 520. One end of the hanging cable 510 is wound around the wire wheel 310. The other end of the hanging cable 510 extends downward after passing around the fixed shaft 431 and connects the hanging part 520.

[0028] When the linear drive 440 is extended and retracted, the first brake plate 432 clamps and releases the hanging cable 510 with the hanging plate 420. When the hanging cable 510 is clamped, the hanging cable 510 downstream of the hanging cable part 430 is not affected, and at this time the motor 300 is pulled to pull the sliding seat part 400; when the hanging cable 510 is released, at this time the motor 300 is pulled to pull the hanging part 520.

[0029] In the working process, in the horizontal movement, the control linear drive 440 clamps the hoisting cable 510 between the first brake plate 432 and the hanging plate 420, controls the motor 300 to work, and moves the sliding seat part 400 to the appropriate position. The sliding of the sliding seat part 400 away from the support column 100 is realized by the slope of the working arm 220 descending. In the vertical movement, the control linear drive 440 releases the hoisting cable 510 between the first brake plate 432 and the hanging plate 420, controls the motor 300 to work, and lifts the hanging part 520 to the appropriate position. In the rotating movement, the working part 200 is manually operated to rotate the support column 100.

[0030] In summary, the rotating seat 210 is arranged at the upper end of the support column 100, the working arm 220 has a downward tendency of 1 to 5 degrees away from the rotating seat 210; the motor 300 is coaxially arranged in the mounting cavity of the rotating seat 210, the upper end of the rotating shaft penetrates the rotating seat 210 and is connected with the wire wheel 310; when the hoisting cable 510 is clamped, the hoisting cable 510 downstream of the hanging cable part 430 will not be affected, at this time the action of the motor 300 will pull the sliding seat part 400 to realize the horizontal movement; when the hoisting cable 510 is released, at this time the action of the motor 300 will pull the hanging part 520 to realize the vertical movement; through the cooperation of the motor 300, the hanging cable part 430 and the linear drive 440, the horizontal movement and the vertical movement are realized, which is low in cost, simple in structure, and provides a basis for improving the hoisting work range.

[0031] Reference Figures 1 to 10 In one embodiment, the linear drive 440 is a double-rod gas / liquid cylinder type, the linear drive 440 includes two output ends and has a middle working position and two end working positions, the output end of the linear drive 440 connected with the fixed shaft 431 is connected with the second brake plate 450, wherein the linear drive 440 is in the middle working position, the first brake plate 432 and the second brake plate 450 are in the free state; the linear drive 440 is in the two end working positions, respectively clamps the first brake plate 432 and the hanging plate 420 and clamps the second brake plate 450 and the working arm 220.

[0032] In the embodiment, the output end of the linear drive 440 is a sliding rod, and the two ends of the sliding rod are output ends. The two ends of the sliding rod are respectively the first brake plate 432 and the second brake plate 450. The sliding rod has a middle working position and two end working positions, so as to realize double effects. In one end position, the first brake plate 432 clamps the hanging plate 420 to fix the hanging cable 510. At this time, the working of the motor 300 can pull the sliding seat part 400 to approach the position of the support column 100, and the sliding of the sliding seat part 400 away from the support column 100 is realized by the slope of the downward working arm 220. In the other end position, the second brake plate 450 clamps the working arm 220 to be fixed. At this time, the sliding seat part 400 cannot slide on the working arm 220, and the working of the motor 300 can lift or lower the hanging part 520. The linear drive is a double-rod pneumatic / hydraulic cylinder type, and a pneumatic source or a hydraulic source is provided according to the requirement. The middle working position of the linear drive 440 has no special working significance, and is only self-provided by the double-rod pneumatic / hydraulic cylinder. By limiting the linear drive 440, the sliding seat part 400 can be fixed in a certain state, so as to provide a basis for the stable lifting of the hanging part 520.

[0033] In one embodiment, the output end of the linear drive 440 is a fixed structure in the circumferential direction.

[0034] In the embodiment, the output end of the linear drive 440 is a sliding rod, and the sliding rod is limited in the circumferential direction, so as to reduce the possibility of structural damage of the linear drive 440 and improve the working effect.

[0035] In one embodiment, the working arm 220 is provided with a first tooth structure in the length direction on one side corresponding to the second brake plate 450, and the second brake plate 450 is provided with a second tooth structure corresponding to the first tooth structure.

[0036] In the embodiment, the combination strength between the working arm 220 and the second brake plate 450 is improved through the interaction of the first tooth structure provided with the second tooth structure. Specifically, the structure forms of the first tooth structure and the second tooth structure are not the focus, and the meshing is the key.

[0037] In one embodiment, a pressure source is provided corresponding to the linear drive 440.

[0038] In the embodiment, the pressure source is provided to eliminate the requirement of an external pressure source. When the linear drive 440 is a double-rod pneumatic cylinder type, the pressure source is a high-pressure gas source; and when the linear drive 440 is a double-rod hydraulic cylinder type, the pressure source is a high-pressure hydraulic oil source.

[0039] Reference Figures 1 to 3In one embodiment, the top of the support column 100 is provided with a mounting slot, and an electromagnet 600 is arranged in the mounting slot. The lower end of the rotating shaft of the motor 300 is connected with a rotating disc 320 which interacts with the electromagnet 600.

[0040] In the present embodiment, the electromagnet 600 is arranged on the support column 100, and the lower end of the rotating shaft of the motor 300 outputs a rotating disc 320. When the electromagnet 600 is powered, a magnetic field is generated to interact with the rotating disc 320 of the motor 300. At this time, the rotation of the motor 300 can drive the working part 200 to rotate. The type of the electromagnet 600 is not the focus, and the magnetic interaction is sufficient. The material of the rotating disc 320 can be ferromagnetic or paramagnetic material, so that the electromagnet 600 and the rotating disc 320 can interact with each other. It should be noted that since the motor 300 interacts with the hoisting cable 510 at the same time, during the rotation of the working part 200, the sliding seat part 400 will slide or the height of the hanging part 520 will change in a small range, which does not interfere with the overall work of the lifting device. Even in some cases, the rotation of the working part 200 and the synchronous work of the sliding seat part 400 are positive, which improves the work efficiency.

[0041] In one embodiment, the switch of the electromagnet 600 is arranged on the working switch.

[0042] In the present embodiment, the switch of the electromagnet 600 is also arranged on the working switch of the motor 300, so as to improve the use efficiency and flexibility. The communication mode between the electromagnet 600 and the working switch can be wireless or wired.

[0043] In one embodiment, the hanging cable part 430 is rotatably arranged on the output end of the linear drive 440.

[0044] In the present embodiment, the hanging cable part 430 is rotatably arranged, so that the hoisting cable 510 can rotate during the work, thereby reducing the work smoothness and the wear of the related components.

[0045] In one embodiment, the support column 100 is telescopic.

[0046] In the present embodiment, the telescopic support column 100 can adjust the working height. For example, if the lifting device is used at a lower height, the telescopic support column 100 can be lowered to adapt to the working height. If the lifting device is used at a higher height, the telescopic support column 100 can be raised to adapt to the working height. The telescopic support column 100 can be in the form of a hydraulic telescopic rod.

[0047] In one embodiment, the working arm 220 is connected to the top of the rotating seat 210 in the height direction.

[0048] In the embodiment, the position of the working arm 220 is lifted, the working height of the lifting device is raised, and the setting angle of the sling cable 510 can approach 90 degrees, so that the lateral force provided by the sling cable 510 on the sliding seat part 400 is weakened, and the braking force required by the second brake plate 450 is reduced.

[0049] The application further provides a method applied to the lifting device with the adjusting function. S1, the electromagnet 600 is controlled to be inoperable, the linear drive 440 is controlled to clamp the first brake plate 432 and the hanging plate 420, and the motor 300 is controlled to work to move the sliding seat part 400. S2, the electromagnet 600 is controlled to be inoperable, the linear drive 440 is controlled to clamp the second brake plate 450 and the working arm 220, and the motor 300 is controlled to work to move the hanging part 520. S3, the electromagnet 600 is controlled to work, and the motor 300 is controlled to work to rotate the working part 200.

[0050] In the step S1, the electromagnet 600 is controlled to be inoperable, so that the working of the motor 300 does not rotate the working part 200. The linear drive 440 is controlled to clamp the first brake plate 432 and the hanging plate 420 (the sling cable 510 is clamped at the position), and the motor 300 is controlled to work to move the sliding seat part 400.

[0051] In the step S2, the electromagnet 600 is controlled to be inoperable, so that the working of the motor 300 does not rotate the working part 200. The linear drive 440 is controlled to clamp the second brake plate 450 and the working arm 220, so that the sliding seat part 400 is fixed, and the motor 300 is controlled to work to move the hanging part 520 to a suitable position.

[0052] In the step S3, the electromagnet 600 is controlled to work, and the motor 300 is controlled to work, so that the working part 200 is rotated to a suitable angle.

[0053] In summary, the hoisting device with adjusting function and the method thereof provided by the application, the rotating seat 210 is rotationally arranged on the upper end of the support column 100, the working arm 220 has a downward tendency of 1-5 degrees in the direction away from the rotating seat 210; the motor 300 is coaxially arranged in the mounting cavity of the rotating seat 210, the upper end of the rotating shaft penetrates through the rotating seat 210 and is connected with the wire wheel 310; when the hoisting cable 510 is clamped, the hoisting cable 510 downstream of the cable hanging part 430 is not acted on, at this time, the action of the motor 300 pulls the sliding seat part 400 to realize the horizontal transfer; when the hoisting cable 510 is released, at this time, the action of the motor 300 pulls the hanging part 520 to realize the vertical transfer; through the cooperation of the motor 300, the cable hanging part 430 and the linear drive 440, the horizontal transfer and the vertical transfer are realized, the cost is low, the structure is simple, and the hoisting work range is improved.
