Description

Technical Field

[0001] This utility model relates to the field of lifting devices and switch cabinets, and in particular to a lifting device and switch cabinet for switch cabinets. Background Technology

[0002] Lifting devices for switchgear and switchgear refer to auxiliary equipment specifically designed for lifting and moving switchgear, as well as electrical complete sets of switchgear used in power systems to realize functions such as power distribution, control, protection and monitoring. Among them, the lifting device is usually composed of components such as hook, load-bearing structure, and drive mechanism. Through reasonable mechanical design, it can safely and stably lift the switchgear to the designated position, which is convenient for installation, maintenance or replacement.

[0003] However, existing lifting devices and switchgear for switchgear have the following disadvantages:

[0004] (1) When the switchgear needs internal inspection, replacement of parts or overall maintenance, the inconvenience of lifting the switchgear may make it difficult to move it from its fixed position or to perform necessary flipping or lifting operations, thereby increasing the difficulty and time cost of the inspection and maintenance, and affecting the efficiency and quality of the maintenance work.

[0005] (2) During the lifting process, when it is inconvenient to clamp and fix the switch cabinet, lifting by relying on a single point or a few contact points is easy to cause a large-scale shaking due to the shift of the center of gravity. This shaking may not only collide with surrounding personnel and equipment, causing personal injury and property damage, but may also cause wear and breakage of lifting ropes or chains and other components, thus causing the switch cabinet to fall.

[0006] Therefore, this utility model provides a lifting device for switch cabinets and a switch cabinet. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a lifting device for switch cabinets and a switch cabinet, including a base 1. The base 1 has a first cavity inside, and an adjustment component 2 is arranged inside the first cavity. The adjustment component 2 includes a motor 21 fixedly connected to the inner wall of the cavity. The output end of the motor 21 is splinedly connected to a transmission rod. One end of the transmission rod is fixedly connected to a worm gear 22. A worm wheel 23 is meshed on the surface of the worm gear 22. A first threaded rod 24 is fixedly inserted into the center of the worm wheel 23. A first threaded slider 25 is threadedly sleeved on the surface of the first threaded rod 24. A connecting rod 26 is fixedly connected to one side of the first threaded slider 25. A connecting rod 26 is fixedly connected to one side of the connecting rod 26. The device includes a connecting block 27, with a sliding block fixedly connected to one side of the connecting block 27. A clamping block 28 is installed inside the connecting block 27, and a clamping assembly 3 is provided on the surface of the connecting block 27. The device can flexibly adjust the position of the clamping block 28 by adjusting the assembly 2, so that when the switch cabinet body 4 needs internal inspection, component replacement or overall maintenance, the switch cabinet body 4 can be quickly lifted and moved from a fixed position, facilitating necessary flipping, lifting and other operations. Compared with traditional switch cabinets that are inconvenient to lift, this device greatly reduces the difficulty of maintenance, saves maintenance time, significantly improves the efficiency and quality of maintenance work, and reduces the downtime of the power system caused by equipment maintenance.

[0028] The clamping assembly 3 includes a rotating rod 31 movably inserted into the surface of the connecting block 27. One end of the rotating rod 31 is fixedly connected to a turntable 32, and one side of the turntable 32 is fixedly connected to a handle 33. An anti-slip sleeve 34 is fixedly fitted onto the surface of the handle 33. A limit ring 35 is fixedly fitted onto the surface of the rotating rod 31. The other end of the rotating rod 31 is fixedly connected to a second threaded rod 36. A second threaded slider 37 is threadedly fitted onto the surface of the second threaded rod 36. A clamping block 28 is fixedly connected to one side of the second threaded slider 37. The clamping assembly 3 can connect to the second threaded block 28 via the second threaded rod 36. The engagement of the threaded slider 37 drives the clamping block 28 to embed into the groove of the switch cabinet body 4, achieving multi-point stable clamping of the switch cabinet body 4. Compared with the traditional method of lifting by relying on a single point or a few contact points, it effectively avoids large-scale swaying caused by the shift of the center of gravity during the lifting process. This not only reduces the risk of personal injury and property damage caused by collision with surrounding personnel and equipment, but also reduces the wear and breakage of lifting ropes or chains caused by swaying, greatly improving the safety of the lifting process and reducing the possibility of the switch cabinet body 4 falling.

[0029] A switch cabinet body 4 is provided on one side of the clamping block 28. The surface of the switch cabinet body 4 is provided with an embedding groove, which is compatible with the clamping block 28. This design can ensure that the clamping block 28 is accurately embedded in the embedding groove. During the lifting process, the two work closely together to form a stable mechanical connection, which greatly enhances the connection strength between the lifting device and the switch cabinet body 4, and further improves the safety and stability of the lifting.

[0030] A cabinet door is installed on one side of the switch cabinet body 4, and a handle 5 is provided on the surface of the cabinet door. The handle 5 makes it convenient to open and close the cabinet door.

[0031] A bracket 6 is fixedly connected to one side of the base 1. The surface of the bracket 6 is provided with a sliding groove, which is compatible with the sliding block. This structural design provides precise guidance and stable support for the movement of the connecting block 27 and the sliding block.

[0032] The inner wall of the cavity is provided with a rotating groove, which is adapted to the worm 22. When the adjustment component 2 is working, the rotating groove restricts the radial displacement of the worm 22 during the rotation process, so that it can rotate precisely around its own axis, ensuring the meshing accuracy and transmission efficiency between the worm 22 and the worm wheel 23.

[0033] The surface of the connecting block 27 is provided with a sliding groove, which is adapted to the second threaded slider 37. When the throttle 33 is turned to drive the second threaded rod 36 to rotate, and the second threaded slider 37 moves under the threaded transmission, the sliding groove ensures that the second threaded slider 37 moves smoothly along the predetermined direction.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: When it is necessary to lift the switch cabinet body 4, the staff first starts the motor 21 in the adjustment component 2. Then the output end of the motor 21 drives the spline-connected transmission rod to rotate, and the transmission rod drives the worm 22 to rotate. Since the worm 22 meshes with the worm wheel 23, the rotation of the worm 22 will drive the worm wheel 23 to rotate. The first threaded rod 24 fixedly inserted at the center of the worm wheel 23 will also rotate. The first threaded slider 25 threaded on the surface of the first threaded rod 24 moves along the axial direction of the first threaded rod 24 under its rotation. The connecting rod 26 fixedly connected to one side of the first threaded slider 25 will also move synchronously, thereby driving the connecting block 27 and the sliding block on the connecting block 27 to slide along the groove on the surface of the bracket 6, so as to realize the horizontal adjustment of the position of the connecting block 27.

[0036] The second step: Rotate the handle 33 to drive the turntable 32 and the rotating rod 31 to rotate. Then, the second threaded rod 36 at the other end of the rotating rod 31 rotates accordingly. The second threaded slider 37, which is threaded on the surface of the second threaded rod 36, moves along the axial direction of the second threaded rod 36 under its rotation. The clamping block 28, which is fixedly connected to one side of the second threaded slider 37, will gradually approach the embedded groove on the surface of the switch cabinet body 4 until the clamping block 28 is embedded in the embedded groove, thus achieving a firm clamping of the switch cabinet body 4. After the clamping is completed, the switch cabinet body 4 can be safely lifted and moved by the lifting device.
