Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting devices, and in particular, it is a hoisting device for installing electromechanical equipment. Background Technology

[0002] Electromechanical equipment generally refers to mechanical, electrical, and electrical automation equipment. In construction, it often refers to a general term for mechanical and piping equipment other than earthwork, carpentry, steel reinforcement, and masonry. When installing electromechanical equipment, hoisting devices are required for auxiliary installation. Currently, most hoisting devices use wire ropes and hooks to lift electromechanical equipment. However, most devices lack protective components. Because the wire ropes are prone to swaying after lifting the electromechanical equipment, the lifted electromechanical equipment will also sway. This swaying electromechanical equipment is not only prone to collisions, but also to injuring workers, reducing the safety of workers during hoisting.

[0003] A Chinese patent (authorization announcement number CN218261685U) discloses a hoisting mechanism for processing electromechanical equipment, which "comprising: a base plate, wherein a braking mechanism is installed at each of the four corners of the bottom of the base plate, the braking mechanism comprising a base frame, rollers, a mounting frame and positioning bolts, a handle welded to the upper left side of the base plate, and a counterweight provided on the upper left side of the base plate."

[0004] It is evident that the cited patent document contains a problem where suspended electromechanical equipment is prone to swaying. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for installing electromechanical equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for installing electromechanical equipment, comprising a hoisting frame, a first drive motor mounted on one side of the hoisting frame, the output end of the first drive motor passing through the hoisting frame and connected to a first bidirectional threaded rod, two moving blocks being threadedly fitted around the periphery of the first bidirectional threaded rod, and hinge plates being hinged to the bottom surfaces of the two moving blocks, a lifting frame being provided in the inner cavity of the hoisting frame, and two bases being symmetrically welded to the top surface of the lifting frame and respectively hinged to the free ends of the two hinge plates, a second bidirectional threaded rod being rotatably provided on the inner side wall of the lifting frame, and two limiting plates for restricting the sides of the electromechanical equipment being threadedly fitted around the periphery of the second bidirectional threaded rod, and a base plate for restricting the bottom surface of the electromechanical equipment being provided on the bottom surface of the two limiting plates.

[0007] Preferably, a second drive motor is installed on one inner wall of the lifting frame, and the output end of the second drive motor is connected and fixed to one end of the second bidirectional threaded rod.

[0008] Preferably, the top surface of the hoisting frame has two upright plates symmetrically welded on, and a rotary motor is installed on one side of one of the upright plates.

[0009] Preferably, the output end of the rotary motor is connected to a take-up roller through the vertical plate, and the free end of the take-up roller is rotatably connected to one side of another vertical plate.

[0010] Preferably, the winding roller has a steel wire rope wound around its periphery, and the free end of the steel wire rope extends into the inner cavity of the lifting frame and is connected to a hook for lifting the electromechanical equipment.

[0011] Preferably, a limiting rod is welded to the inner wall of the hoisting frame and to one side of the first bidirectional threaded rod, and both of the moving blocks are slidably sleeved on the periphery of the limiting rod.

[0012] Preferably, the inner wall of the lifting frame is welded with a sliding rod, and both limiting plates are slidably sleeved on the periphery of the sliding rod.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The hoisting device for installing electromechanical equipment shown includes a hoisting frame 1. Two upright plates 12 are symmetrically welded to the top surface of the hoisting frame 1. A rotary motor 13 is installed on one side of one of the upright plates 12. The output end of the rotary motor 13 passes through the upright plate 12 and is connected to a take-up roller 14. The free end of the take-up roller 14 is rotatably connected to one side of the other upright plate 12. A steel wire rope 15 is wound around the periphery of the take-up roller 14. The free end of the steel wire rope 15 passes through the inner cavity of the hoisting frame 1 and is connected to a hook 16 for hoisting the electromechanical equipment. By turning on the rotary motor 13, the take-up roller 14 can be rotated, thereby loosening the steel wire rope 15 and allowing the hook 16 to move downward, thus suspending the electromechanical equipment. After suspending the electromechanical equipment, turning on the rotary motor 13 again can drive the take-up roller 14 to rotate in the opposite direction, allowing the take-up roller 14 to wind up the steel wire rope 15, thereby driving the hook 16 to move upward, thus hoisting the electromechanical equipment.

[0028] A first drive motor 2 is installed on one side of the hoisting frame 1. The output end of the first drive motor 2 passes through the hoisting frame 1 and is connected to a first bidirectional threaded rod 3. Two moving blocks 4 are threaded around the periphery of the first bidirectional threaded rod 3. By turning on the first drive motor 2, the first bidirectional threaded rod 3 can be rotated, thereby driving the two moving blocks 4 to move in relative or opposite directions.

[0029] The bottom surfaces of the two moving blocks 4 are hinged with hinge plates 5. The inner cavity of the hoisting frame 1 is equipped with a lifting frame 6. The top surface of the lifting frame 6 has a through hole for the steel wire rope 15 to pass through. The top surface of the lifting frame 6 is symmetrically welded with two bases 7 that are respectively hinged to the free ends of the two hinge plates 5. The two hinge plates 5 are initially tilted. Therefore, when the two moving blocks 4 move in opposite directions, they will respectively drive the two hinge plates 5 to move in opposite directions at the ends that are hinged to the moving blocks 4, so that the two hinge plates 5 gradually become vertical, thereby driving the lifting frame 6 to move downward. Conversely, when the two moving blocks 4 move in opposite directions, they will respectively drive the two hinge plates 5 to move in opposite directions at the ends that are hinged to the moving blocks 4, so that the two hinge plates 5 gradually become tilted, thereby driving the lifting frame 6 to move upward.

[0030] The inner wall of the lifting frame 6 is rotatably provided with a second bidirectional threaded rod 8. The periphery of the second bidirectional threaded rod 8 is threaded with two limiting plates 9 for restricting the sides of the electromechanical equipment. The bottom surface of each of the two limiting plates 9 is provided with a base plate 10 for restricting the bottom surface of the electromechanical equipment. A second drive motor 11 is installed on one side of the inner wall of the lifting frame 6. The output end of the second drive motor 11 is connected and fixed to one end of the second bidirectional threaded rod 8. When the electromechanical equipment is lifted, so that the bottom surface of the electromechanical equipment is higher than the two base plates 10, the second drive motor 11 can drive the second bidirectional threaded rod 8 to rotate, thereby driving the two limiting plates 9 to move in opposite directions, so that the two limiting plates 9 abut against the electromechanical equipment, protecting and limiting the sides of the electromechanical equipment.

[0031] When the limiting plate 9 is against the electromechanical equipment, the two base plates 10 will be below the electromechanical equipment. When the first drive motor 2 is turned on, the lifting frame 6 will be moved upward through the first bidirectional threaded rod 3, the two moving blocks 4, the two hinge plates 5 and the two bases 7, so that the two base plates 10 can be against the bottom surface of the electromechanical equipment, which can lift the electromechanical equipment and protect and limit the bottom surface of the electromechanical equipment. This reduces the shaking of the electromechanical equipment after it is lifted, reduces the possibility of collisions and injuries to workers caused by the shaking of the electromechanical equipment, and improves the safety of workers during hoisting.

[0032] A limiting rod 17 is welded to the inner wall of the hoisting frame 1 and to one side of the first bidirectional threaded rod 3. Both moving blocks 4 are slidably sleeved on the periphery of the limiting rod 17. When the two moving blocks 4 move, they will move on the periphery of the limiting rod 17, thus limiting the movement trajectory of the two moving blocks 4.

[0033] The inner wall of the lifting frame 6 is welded with a sliding rod 18. Two limiting plates 9 are slidably sleeved on the periphery of the sliding rod 18. When the two limiting plates 9 move, they will reciprocate on the periphery of the sliding rod 18, which can limit the movement trajectory and prevent deviation.

[0034] Working principle:

[0035] The hoisting device for installing the electromechanical equipment moves the hoisting frame 1 to the location of the electromechanical equipment, then hangs the equipment on the hook 16. The rotary motor 13 is then turned on, which drives the winding roller 14 to rotate, thereby winding the wire rope 15 and lifting the electromechanical equipment. When the equipment is lifted and its bottom surface is higher than the two base plates 10, the second drive motor 11 is turned on. This drives the two limiting plates 9 to move in opposite directions via the second bidirectional threaded rod 8, causing the two limiting plates 9 to abut against the electromechanical equipment, protecting and limiting the sides of the equipment. When the two limiting plates 9 abut against... When hoisting the electromechanical equipment, the two base plates 10 will be positioned below the equipment. Then, the first drive motor 2 is turned on, which drives the two moving blocks 4 to move in opposite directions via the first bidirectional threaded rod 3. In turn, the two hinge plates 5 drive the lifting frame 6 to move upward, allowing the two base plates 10 to abut against the bottom surface of the electromechanical equipment. This supports the equipment and protects and limits its bottom surface, reducing the swaying of the equipment after hoisting. This reduces the risk of collisions and injuries to workers caused by the swaying of the equipment, thus improving the safety of workers during hoisting.
