DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 5 , an engine transmission powertrain hoisting equipment, including a hanging plate 1, a rectangular opening is horizontally opened on the upper surface of the hanging plate 1, a first threaded rod 2 is horizontally rotatably installed in the rectangular opening, a slider 3 is threadedly sleeved on the first threaded rod 2, two mounting blocks 4 are arranged on the lower surface of the hanging plate 1, a mounting groove is horizontally opened on the lower surface of the mounting block 4, a second threaded rod 5 with opposite thread directions at left and right ends is horizontally rotatably installed in the mounting groove, a slide seat 6 is symmetrically threadedly sleeved on the second threaded rod 5, L-shaped clamping plates 7 are fixedly installed on the lower surfaces of the two slide seats 6, one of the clamping plates 7 is larger than the other clamping plate 7, and a socket 8 for inserting the end of the other clamping plate 7 is horizontally opened on the bottom surface.

[0026] One of the mounting blocks 4 is fixedly mounted on the lower surface of the hanging plate 1, and the other mounting block 4 is fixedly mounted on the lower surface of the slider 3. One end of the two second threaded rods 5 pass through the mounting block 4 and are fixedly mounted with an adjusting wheel 9. The side wall of the hanging plate 1 is fixedly mounted with a driving motor 10, and the output shaft of the driving motor 10 is fixedly connected to the first threaded rod 2.

[0027] Before the power assembly needs to be hoisted, first determine the length of the power assembly, then start the drive motor 10, control the first threaded rod 2 to rotate, so that the slider 3 threadedly sleeved on the first threaded rod 2 moves with one of the mounting blocks 4 until the distance between the two mounting blocks 4 meets the hoisting power assembly. At this time, place the power assembly between the multiple clamping plates 7, and then control the multiple clamping plates 7 to move by rotating the second threaded rod 5 until the multiple clamping plates 7 are tightly against the power assembly. The clamping and fixing of the power assembly can be completed, and the hoisting of power assemblies of different sizes and lengths can be completed quickly, which is convenient and fast, and improves the practicality of the device.

[0028] A through-hole is provided on the surface of the adjusting wheel 9, and an adsorption component is provided in the through-hole. The adsorption component is used to limit the rotation of the adjusting wheel 9. The adsorption component includes a hollow rod 11 with one end designed to be closed and horizontally slidably configured in the through-hole, and a suction cup 12 fixedly installed at the open end of the hollow rod 11. The two suction cups 12 correspond to the positions of the two mounting blocks 4 respectively. A sealing opening is provided at the closed end of the hollow rod 11, and a rotating shaft 13 is sealed and rotatably installed in the sealing opening. An arc-shaped opening 15 is provided on the surface of the hollow rod 11. An arc-shaped plate 14 for covering the arc-shaped opening 15 is fixedly installed at one end of the rotating shaft 13 located in the hollow rod 11 through a connecting rod. A torsion spring 16 is sleeved on the rotating shaft 13, and a disc 17 is fixedly installed at one end of the rotating shaft 13 located outside, and the two ends of the torsion spring 16 are fixedly connected to the disc 17 and the hollow rod 11 respectively.

[0029] The second threaded rod 5 can be controlled to rotate by turning the adjusting wheel 9, and when the second threaded rod 5 is turned to control the clamping plate 7 to move to a suitable position, the hollow rod 11 can be controlled to move in a direction close to the mounting block 4 until the suction cup 12 is tightly against the mounting block 4. At this time, the gas in the suction cup 12 will slip out from the gap between the suction cup 12 and the contact surface with the mounting block 4, thereby completing the adsorption, and then limiting the rotation of the adjusting wheel 9 and the second threaded rod 5, preventing the second threaded rod 5 from rotating due to the influence of external forces during the lifting process, thereby causing the clamping plate 7 to lose its clamping and fixation of the power assembly.

[0030] When it is necessary to release the adsorption of the suction cup 12, the arc plate 14 is controlled to no longer cover the arc opening 15 by rotating the rotating shaft 13. At this time, the gas in the outside will enter the hollow rod 11 through the arc opening 15, thereby releasing the adsorption of the suction cup 12 and the mounting block 4. It is convenient and quick. When the rotating shaft 13 is released, the rotating shaft 13 and the arc plate 14 will quickly rotate and reset under the elastic potential energy of the torsion spring 16, and the arc plate 14 will cover the arc opening 15 again, making it in a closed state.

[0031] The diameters of the disc 17 and the suction cup 12 are both larger than the diameter of the through-hole, which can prevent the hollow rod 11 from moving out of the through-hole.

[0032] A mounting plate is fixedly installed on the side wall of the hanging plate 1 away from the driving motor 10, and a third threaded rod 18 is rotatably installed on the surface of the mounting plate. A sliding seat is threadedly sleeved on the third threaded rod 18, and a semi-annular material receiving plate 20 is fixedly installed on the lower surface of the sliding seat through a connecting rod 19. A protective layer is bonded to the inner wall of the material receiving plate 20, and the material of the protective layer is rubber.

[0033] After the power assembly is fixed, the third threaded rod 18 can be rotated to control the sliding seat threadedly sleeved on the third threaded rod 18 to move the receiving plate 20 laterally until the receiving plate 20 moves to the bottom of the power assembly and then hoisted.

[0034] The receiving plate 20 below the power assembly can prevent the power assembly from falling directly to the ground even after the multiple clamping plates 7 fail to fix the power assembly, but will fall into the receiving plate 20 below, eliminating the safety hazard of the power assembly falling directly.

[0035] In the utility model, before the power assembly needs to be hoisted, the length of the power assembly is first determined, and then the driving motor 10 is started to control the rotation of the first threaded rod 2, so that the slider 3 threadedly sleeved on the first threaded rod 2 moves with one of the mounting blocks 4 until the distance between the two mounting blocks 4 meets the hoisting power assembly. At this time, the power assembly is placed between the multiple clamping plates 7, and then the multiple clamping plates 7 are controlled to move by rotating the second threaded rod 5 until the multiple clamping plates 7 are tightly against the power assembly. The clamping and fixing of the power assembly can be completed, and the hoisting of power assemblies of different sizes and lengths can be completed quickly, which is convenient and fast, and improves the practicality of the device.

[0036] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
