Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment, specifically a heavy-duty lifting module for electrical systems. Background Technology
[0002] Ball bearing slides place steel balls on a high-precision track surface, transforming the sliding friction between the guide surfaces into rolling friction, achieving high-precision and stable linear motion. With the increasing application of slide rail technology in the market, customers require slide rails with lifting functions, allowing for a more compact electrical enclosure structure. Existing lifting slide rail technologies all use sheet metal and spring modules added to the slide rail structure, but their load and lifting capacity are all below 50kg, unable to meet the heavy load requirements of 150kg in industrial applications. Furthermore, if the application scenario is an electrical environment, a corresponding power interface cannot be provided; this device needs to achieve the lifting and sliding functions of a 150kg module under manual operation only. Conventional hydraulic lifting and electric cylinder lifting require external energy input, thus failing to achieve this purely mechanical operation. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned defects and propose a load-bearing lifting module with high precision, smooth movement, large load capacity, and adjustable stroke.
[0004] To achieve the above objectives, this utility model is implemented as follows:
[0005] A heavy-duty lifting module for an electrical system includes a base frame, vertical guide rail modules, electrical module fixing brackets, and a lifting module. The base frame includes two symmetrically arranged side plates, with vertical guide rail modules symmetrically arranged at both ends of the inner side of the two side plates. The electrical module fixing brackets also have two pairs, each connected to the vertical guide rail modules on the two side plates. The lifting module is connected to both the electrical module fixing brackets and the side plates. The vertical guide rail modules of the electrical module fixing brackets move up and down under the action of the lifting module.
[0006] The aforementioned heavy-duty lifting module for electrical systems also includes a handle, the two ends of which are connected to the side plates on both sides, forming an integral base frame.
[0007] The heavy-duty lifting module for the electrical system also includes a base frame slide rail, which is horizontally arranged on the outside of the two side plates, and the base frame is connected and fixed to the outside through the base frame slide rail.
[0008] The lifting module proposed in this utility model adopts a design scheme of horizontal movement of an integral slide rail supplemented by vertical lifting of the lifting module, realizing the horizontal extension and retraction of the electrical module fixing bracket and the vertical lifting and lowering. The integral slide rail features high precision, smooth movement, large load capacity, and adjustable stroke during extension and retraction. The combination structure of the lifting module and the vertical guide rail offers convenient and quick lifting, simple operation, smooth movement, and adjustable lifting stroke. This mechanism is suitable for working environments with limited space, large loads, and where automated equipment requiring external energy input, such as hydraulic or electric cylinders, cannot be used and can only be operated manually.
[0009] The aforementioned structural design enables the module, after being equipped with the electrical module, to achieve smooth lifting, pulling out, and pushing in movements, all achievable through the detachable external handle. The entire mechanism boasts advantages such as high mechanical strength, high safety, stable movement, compact overall dimensions, simple and convenient operation, and adjustable stroke.
[0010] The aforementioned heavy-duty lifting module for electrical systems includes a scissor arm, a gas spring for driving the scissor arm, and a horizontal guide rail for limiting the movement trajectory of the scissor arm. The scissor arm is connected to a side plate and an electrical module mounting bracket, respectively. The pivot point of the scissor arm is also connected to the horizontal guide rail and the gas spring, respectively. The gas spring and the horizontal guide rail are also connected to the side plate. The scissor arm performs longitudinal compression or extension under the push of the gas spring. Since the pivot point of the scissor arm is also connected to the horizontal guide rail, during the movement of the scissor arm, its pivot point slides back and forth in the horizontal guide rail, realizing the guiding function of the scissor arm.
[0011] The heavy-duty lifting module for the electrical system has the same connection point between one end of the gas spring and the horizontal guide rail and the side plate.
[0012] The lifting module employs a classic compressible and extendable scissor arm mechanism, supplemented by guide rails in both the horizontal and vertical directions, resulting in smoother movement and higher structural strength. Under normal operating conditions, the scissor arm is extended due to the weight of the electrical module and mechanism itself. When a certain height needs to be raised, the detachable handle at the front allows for manual lifting, compressing the scissor arm and raising the entire mechanism. To balance the module's weight, multiple gas springs are connected to the upper end of the scissor arm, allowing for easy lifting by a single person. A mechanical locking device is added at the appropriate position, enabling self-locking at a certain height without requiring prolonged manual support. Sliding guide rails are installed in both the vertical and horizontal directions, resulting in smoother, more stable movement with less resistance. The compact overall structure achieves simple operation and smooth lifting motion. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the operation process of the heavy-duty lifting module shown in this example. Detailed Implementation
[0015] The present invention will be further illustrated by specific embodiments below.
[0016] like Figure 1 , Figure 2 As shown, a heavy-duty lifting module for an electrical system includes a base frame 1, a vertical guide rail module 2, an electrical module fixing bracket 3, and a lifting module 4. The base frame 1 includes two symmetrically arranged side plates 11, with vertical guide rail modules 2 symmetrically arranged at both ends of the inner side of the two side plates 11. The electrical module fixing bracket 3 also has two pairs, each connected to the vertical guide rail modules 2 on the two side plates 11. The lifting module 4 is connected to the electrical module fixing bracket 3 and the side plates 11 respectively. The vertical guide rail modules 2 of the electrical module fixing bracket 3 move up and down under the action of the lifting module 4.
[0017] The aforementioned heavy-duty lifting module for electrical systems also includes a handle 5, the two ends of which are connected to the side plates 11 on both sides, forming an integral base frame 1.
[0018] The heavy-duty lifting module for the electrical system also includes a base frame slide rail 6, which is horizontally arranged on the outside of the two side plates 11, and the base frame 1 is connected and fixed to the outside through the base frame slide rail 6.
[0019] The aforementioned heavy-duty lifting module for electrical systems includes a lifting module 4 comprising a scissor arm 41, a gas spring 42 for driving the scissor arm 41, and a horizontal guide rail 43 for limiting the movement trajectory of the scissor arm 41. The scissor arm 41 is connected to the side plate 11 and the electrical module fixing bracket 3, respectively. The pivot point of the scissor arm 41 is also connected to the horizontal guide rail 43 and the gas spring 42, respectively. The gas spring 42 and the horizontal guide rail 43 are also connected to the side plate 11. The scissor arm 41 performs longitudinal compression or extension under the push of the gas spring 42. Since the pivot point of the scissor arm 41 is also connected to the horizontal guide rail 43, during the movement of the scissor arm 41, its pivot point slides back and forth in the horizontal guide rail 43, thereby achieving the guiding function of the scissor arm 41.
[0020] In the heavy-duty lifting module for the electrical system, one end of the gas spring 42 and the horizontal guide rail 43 are connected to the same point as the side plate 11.
[0021] The lifting module shown in this embodiment can realize the lifting and pulling action of electrical modules with large loads. It adopts a slide rail and scissor arm design, which has the advantages of high mechanical strength, high safety and smooth movement. Furthermore, this mechanism can be used in working environments with narrow space where it is not possible to use automated equipment that requires external energy input, such as hydraulic or electric cylinders. It has the advantages of compact overall structure, simple operation and convenient and quick operation. Moreover, the stroke of this mechanism can be adjusted to the required position according to the actual working conditions, realizing the advantage of adjustable stroke.
