Description

Technical Field

[0001] The utility model relates to the technical field of electric lifting equipment, in particular to an electric equipment lifting device. Background Art

[0002] Power equipment hoisting refers to the process of using lifting equipment to lift and transport power equipment from one location to another. During hoisting, the equipment must be moved safely, stably, and efficiently to minimize damage and operational risks. Therefore, the stability of the clamping mechanism is particularly important.

[0003] The existing technology has the following deficiencies: The prior art, "A lifting device for electric power equipment" with publication number CN112010173A, "comprises a base, a limiting mechanism, a lifting mechanism, and a fixing mechanism, wherein the limiting mechanism comprises a transverse plate and a limiting assembly, the lifting mechanism comprises a drive box, a pull rope, and a storage box, and the fixing mechanism comprises a fixing block and a fixing assembly."

[0004] The above structure realizes the lifting of power equipment through the cooperation of the limiting mechanism, the lifting mechanism and the fixing mechanism, but the structure does not make any improvement to the clamping steps during lifting. During the lifting operation of power equipment, the equipment with a tubular structure is difficult to ensure its lifting stability due to its smooth curved surface on the outside, and the current lifting clamping structure cannot self-adjust according to the size of the lifting equipment, and has poor applicability. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a lifting device for electric equipment, which solves the current problems of poor applicability and difficulty in lifting smooth curved surfaces.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lifting device for electric power equipment, comprising a centering shaft, a threaded column, and a handle, wherein the threaded column is arranged on the upper end surface of the centering shaft, and the handle is arranged on the upper end of the threaded column;

[0007] A displacement support plate is provided on the periphery of the centering shaft, and a connecting rod is provided on the side end of the displacement support plate;

[0008] The position-changing support plate further comprises an axle seat and an adjusting rod. The axle seat is fixedly mounted on the inner wall end surface of the position-changing support plate, and the adjusting rod is movably connected to the outer side of the axle seat.

[0009] As an optimal technical solution of the present invention, the centering shaft also includes a movable end connecting ring and a fixed end connecting ring. The movable end connecting ring is movably connected to the outer end face of the threaded column, and the fixed end connecting ring is fixedly installed at the end of the centering shaft close to the threaded column.

[0010] As a preferred technical solution of the present invention, the displacement support plate is configured as a petal structure, a single body of which adopts an outward-expanding arc surface structure and is specifically made of plastic material.

[0011] As a preferred technical solution of the present invention, four groups of shaft seats are provided on the periphery of the movable end connecting ring, and four groups of adjustment rods connected to the displacement support plates are provided at the outer ends of the shaft seats at this position.

[0012] As a preferred technical solution of the present invention, the displacement support plate is designed with four petals in a group, and there are two groups in total, which are respectively distributed near the upper and lower ends of the centering shaft.

[0013] As a preferred technical solution of the present invention, the bottom end of the threaded column is welded to the top end of the centering shaft, and the handle is welded to the top outer end surface of the threaded column.

[0014] As a preferred technical solution of the present invention, both ends of the adjusting rod are provided with shaft structures passing through them, and a rotational connection relationship is established between them.

[0015] Compared with the prior art, the present invention provides a lifting device for electric equipment:

[0016] The electric power equipment lifting device is provided with a centering shaft, an adjusting rod, a connecting rod, a threaded column and a displacement support plate. When the device is in use, the operator installs the structure on the lower end of the suspension device to be used as a clamping mechanism. When the tubular electric power equipment needs to be lifted, the operator inserts the centering shaft of the external suspension equipment into the middle of the tubular equipment, and then twists the handle to move the movable end connecting ring downward on the outer end of the threaded column. As the movable end connecting ring continues to move, the shaft seat provided at its outer end applies pressure to the adjusting rod. At the same time, the shaft seat on the outer periphery of the fixed end connecting ring also applies pressure to the adjusting rod connected to the outer end. The simultaneous pressure from the upper and lower ends causes the adjusting rod to support the displacement support plate outward. As the displacement support plate expands, the connecting rod drives the displacement support plate on the outer periphery of the bottom end of the centering shaft to expand outward synchronously until the displacement support plate is tightly attached to the inside of the tubular electric power equipment. At this time, the external suspension structure can be started to complete the lifting.

[0017] The above settings and processes can make the device have the following beneficial effects:

[0018] Through the cooperation of the centering shaft, threaded column, adjusting rod and variable position support plate, the distance between the variable position support plate and the centering shaft in the equipment can be adjusted at will, thereby improving the applicability of the structure for lifting power equipment. Compared with the traditional lifting and clamping method, this solution supports the tubular structure from the inside to the outside, increases friction, and greatly improves the clamping stability.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In this embodiment: a lifting device for electric power equipment includes a centering shaft 1, a threaded column 2, and a handle 3, wherein the threaded column 2 is arranged on the upper end surface of the centering shaft 1, and the handle 3 is arranged on the upper end of the threaded column 2;

[0026] A displacement support plate 4 is provided on the periphery of the centering shaft 1, and a connecting rod 5 is provided on the side end of the displacement support plate 4;

[0027] The displacement support plate 4 further includes an axle seat 401 and an adjusting rod 402 . The axle seat 401 is fixedly mounted on the inner wall end surface of the displacement support plate 4 , and the adjusting rod 402 is movably connected to the outer side of the axle seat 401 .

[0028] In this embodiment, the centering shaft 1 further includes a movable end connecting ring 101 and a fixed end connecting ring 102. The movable end connecting ring 101 is movably connected to the outer end surface of the threaded column 2, and the fixed end connecting ring 102 is fixedly installed at the end of the centering shaft 1 near the threaded column 2. The displacement support plate 4 is configured as a petal structure, and its single body adopts an outwardly expanding arc surface structure and is specifically made of plastic material.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the displacement support plate 4 made of plastic material can increase the friction force during clamping, and the displacement support plate 4 with a petal structure enables the power equipment to be evenly pressured during the lifting process;

[0030] In this embodiment, four sets of shaft seats 401 are provided on the periphery of the movable end connecting ring 101, and four sets of adjustment rods 402 connected to the position-shifting support plate 4 are provided at the outer ends of the shaft seats 401 at this position; the position-shifting support plate 4 adopts a design of four petals per group, and a total of two sets are provided, respectively distributed near the upper and lower ends of the centering shaft 1;

[0031] Specifically, such as Figure 2 and Figure 3 As shown, by providing two sets of displacement support plates 4, the upper and lower ends of the centering shaft 1 can be expanded evenly, so that the expansion pressure is more evenly distributed;

[0032] In this embodiment, the bottom end of the threaded column 2 is welded to the top of the centering shaft 1, and the handle 3 is welded to the top outer end surface of the threaded column 2; the ends of both sides of the adjusting rod 402 are provided with an axis structure passing through them, and a rotational connection relationship is established between them.

[0033] The working principle and usage process of the present invention are as follows: when the equipment is in use, the operator installs the structure on the lower end of the suspension device as a clamping mechanism. When the tubular power equipment needs to be lifted, the operator inserts the centering shaft 1 of the external suspension equipment into the middle of the tubular equipment, and then twists the handle 3 to move the movable end connecting ring 101 downward on the outer end of the threaded column 2. As the movable end connecting ring 101 continues to move, the shaft seat 401 set at its outer end applies pressure to the adjusting rod 402. At the same time, the shaft seat 401 outside the fixed end connecting ring 102 also applies pressure to the adjusting rod 402 connected to the outer end. The simultaneous pressure from the upper and lower ends causes the adjusting rod 402 to support the displacement support plate 4 outward. As the displacement support plate 4 expands, the connecting rod 5 drives the displacement support plate 4 outside the bottom end of the centering shaft 1 to expand outward synchronously until the displacement support plate 4 is close to the inside of the tubular power equipment. At this time, the external suspension structure can be started to complete the lifting.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
