Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical construction technology, and in particular to an electrical construction hoisting frame. Background Technology
[0002] During electrical installation work, electrical cabinets and other electrical equipment are often large and heavy. Therefore, these heavy electrical devices usually need to be lifted and moved during construction. Currently, the common practice is to install lifting rings on the top of electrical cabinets and other equipment to facilitate hoisting. However, this method often leads to deformation of the top plate of the electrical cabinet or even disengagement of the lifting rings, which can cause the equipment to fall and be damaged. In severe cases, it can even cause personal injury or death. Therefore, a hoisting frame is necessary.
[0003] For example, an electrical construction hoisting frame with the publication (announcement) number CN208471367U includes a hoisting frame sleeve with a "U" shaped cross section. Several lifting rings are symmetrically arranged on the top of the hoisting frame sleeve. Threaded tubes are vertically arranged on both sides of the hoisting frame sleeve. Threaded rods are threadedly connected to the two threaded tubes. A pressure plate is vertically arranged at one end of each threaded rod located inside the hoisting frame sleeve. A suction cup is arranged on the side of the pressure plate away from the threaded rod. A handle is vertically arranged at one end of each threaded rod located outside the hoisting frame sleeve.
[0004] In summary, the existing technology has the following technical problems: Although the existing technology can achieve the hoisting of electrical cabinets, the hoisting frame is U-shaped and has no protection on both sides, which poses certain risks during the hoisting process. Therefore, we propose an electrical construction hoisting frame. Utility Model Content

[0032] Example 2
[0033] Further optimizations to Example 1, specifically, such as... Figure 5-6 As shown, one of the L-shaped protective frames 2 is equipped with an opening and closing mechanism on its inner side, which is used to open and close one end of the hoisting frame 1.

An L-shaped mounting bracket 17 is fixed to the inner side of one of the L-shaped protective frames 2, and a battery 18 is fixed to the inner side of the L-shaped mounting bracket 17. A self-locking motor 19, an RV030-80 worm gear motor, is fixed to one end of the L-shaped mounting bracket 17. The self-locking motor 19 is electrically connected to the battery 18 via wires. A double-headed rod 20 is fixed to the output end of the self-locking motor 19, and auxiliary components are assembled at both ends of the double-headed rod 20. When the self-locking motor 19 is started, its output end drives the double-headed rod 20 to rotate forward, causing the double-headed rod 20 to pull the transmission rod 21 to move. Simultaneously, two limiting posts are provided on the L-shaped protective frame 2 near the double-headed rod 20, which limit the angle of the double-headed rod 20, allowing the two protective doors 24 to open or close.
[0035] The auxiliary components include a transmission rod 21, a folding rod 22, a guide rod 23, and a protective door 24.

[0036] The L-shaped protective frame 2 has guide slope recesses 25 on both sides inside. The guide slope recesses 25 are slidably connected to the protective door 24. The guide slope recesses 25 can guide and limit the movement of the protective door 24.
[0037] In summary:
[0038] This utility model addresses the technical problem that, while existing technologies can achieve the hoisting of electrical cabinets, the hoisting frame is U-shaped with no protection on both sides, posing a certain risk during the hoisting process. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:
[0039] During use, the self-locking motor 19 is first started. The output end of the self-locking motor 19 drives the double-headed rod 20 to rotate in the forward direction, causing the double-headed rod 20 to pull the transmission rod 21 to move. Because the transmission rod 21 is rotatably connected to the folding rod 22, the folding rod 22 is rotatably connected to the L-shaped protective frame 2, and the folding rod 22 is rotatably connected to the protective door 24, and the protective door 24 is rotatably connected to the guide rod 23, the folding rod 22 can pull the protective door 24 to move. Under the limiting guidance of the guide rod 23, the protective door 24 moves along the guide slope notch 25, realizing that the two protective doors 24 move in a direction away from each other, so that the L-shaped protective frame 2 is opened, and then the lifting frame 1 is opened. Then, the handle 6 is pulled down, and the handle 6 is in the position of Figure 2 In the state of being in the middle, the electrical cabinet is then placed into the hoisting frame 1. Then, the output end of the self-locking motor 19 is controlled to drive the double-headed rod 20 to rotate in the opposite direction, so that the protective door 24 is closed.
[0040] Finally, pull the handle 6 upwards, causing the handle 6 to drive the rotating rod 5 to rotate. The rotating rod 5 drives the first connecting rod 7 to rotate, which in turn causes the first connecting rod 7 to push the guide shaft 9 to slide along the arc groove 10 through the second connecting rod 8. When the guide shaft 9 enters the vertical groove 11, the guide shaft 9 and the slider 12 are simultaneously in the vertical groove 11, forming a rotation dead point. Without external force, it cannot be pushed back by the elastic force of the compression spring 15. At the same time, the T-shaped foot 13 continues to press down on the inclined panel 14 until the cover plate 16 presses on the electrical cabinet, forming a comprehensive protection for the electrical cabinet in cooperation with the hoisting frame 1.
[0041] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:
[0042] 1. Through the structural design of the protective mechanism, this utility model makes it easy for the device to cooperate with the hoisting frame 1 to provide comprehensive protection for the electrical cabinet placed in the hoisting frame 1, prevent the risk of falling during hoisting, and improve the safety of the device.
[0043] 2. Through the opening and closing mechanism and the structural design of the L-shaped protective frame 2, this utility model allows one side of the L-shaped protective frame 2 to be opened, making it convenient for users to put the electrical cabinet into the hoisting frame 1 from the side, thus increasing the ease of use.
