Description

Technical Field

[0001] This utility model relates to the field of installation auxiliary technology for high and low voltage switchgear, and in particular to an installation auxiliary device for high and low voltage switchgear. Background Technology

[0002] In the field of modern power engineering, high and low voltage switchgear (referred to as "switchgear") is the core equipment for power distribution and control. It is huge in size, and a single cabinet often weighs 300-1000 kilograms. The traditional cabinet transportation and placement process is one of the most time-consuming, risky, and labor-intensive parts of the entire installation process.

[0003] For a long time, the transfer and initial placement of switchgear after unloading from warehouses or transport vehicles has mainly relied on two types of tools: ordinary forklifts or manual hoisting with simple handling trays. However, both methods have the following shortcomings: the fork spacing of ordinary forklifts is usually between 500mm and 1200mm, while the fork slots of different switchgear models are between 500-700mm, making existing simple handling trays unusable. The spacing of existing handling tools is not adjustable, and most handling tools are of fixed size, unable to flexibly adapt to the fork slot spacing requirements of different cabinets. Fixed-size handling tools cannot be adjusted according to the fork slot position of a specific switchgear, resulting in time-consuming and labor-intensive handling, high manual labor intensity, poor cabinet stability, and potential personal safety hazards, especially when handling large medium-voltage switchgear or extra-heavy low-voltage switchgear.

[0004] Therefore, this application provides an installation auxiliary device for high and low voltage switchgear to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide an installation auxiliary device for high and low voltage switchgear, which solves the problems of existing handling tools being unable to be adjusted according to the fork slot position of a specific switchgear, resulting in time-consuming and labor-intensive handling of the switchgear, high manual labor intensity, poor stability of the switchgear, and potential personal safety hazards.

[0006] To solve the above-mentioned technical problems, this utility model provides an installation auxiliary device for high and low voltage switchgear, including a frame, with a support plate A and a support plate B adapted and slidably mounted on the upper surface of the frame. Forklift slots A and B are longitudinally connected on both support plates A and B. Support plates A and B can be independently adjusted horizontally and drive the forklift slots A and B to move, thereby adjusting the distance between the forklift slots A and B.

[0007] A further improvement of this utility model is that two longitudinal groove beams are arranged longitudinally and symmetrically at both ends of the lower surface of the frame body, and two gravity wheels are symmetrically arranged on each longitudinal groove beam.

[0008] A further improvement of this utility model is that two transverse groove beams are arranged laterally and symmetrically on the lower surface of the frame body, with both ends of the transverse groove beam abutting against the inner side of the longitudinal groove beam body.

[0009] A further improvement of this utility model is that: the transverse groove beam body is located inside the gravity wheel, and an adjusting screw is adapted and arranged laterally inside the transverse groove beam, with one end of the adjusting screw body adapted to extend through the longitudinal groove beam to the outside of the frame.

[0010] A further improvement of this utility model is that the other end of the adjusting screw body is movably fixed inside the transverse groove beam by a screw limiting block.

[0011] A further improvement of this utility model is that: several nuts are appropriately fitted on the adjusting screw body, and the nuts are respectively fixed on the support plate A and the support plate B.

[0012] A further improvement of this utility model is that: one end of the adjusting screw body extends to the outside of the frame and an adjusting ring is provided, and the user drives the nut to generate displacement by rotating the adjusting ring.

[0013] A further improvement of this utility model is that the inner diameter of both forklift slot A and forklift slot B is larger than the outer diameter of the forklift forks.

[0014] A further improvement of this utility model is that several fixing rings are symmetrically arranged on both sides of the frame body, and the fixing rings are used to fix the high and low voltage switchgear by pull ropes.

[0015] A further improvement of this utility model is that two protective corners are symmetrically arranged on the outer edges of the tray A and tray B, and the protective corners on tray A and tray B together limit the high and low voltage switchgear.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides an installation auxiliary device for high and low voltage switchgear, which adopts an adjusting screw design. Several nuts are appropriately installed on the adjusting screw, and the nuts are fixed on the support plate A and support plate B respectively. By rotating the adjusting screw, the nuts drive the forklift slots A and B on support plate A and support plate B to adjust the horizontal spacing. It can be adjusted according to the position of the forklift slots of the switchgear, which facilitates forklift handling and transfer, improves handling efficiency, reduces manual labor intensity, and improves the stability of switchgear handling.

[0018] 2. This utility model provides an installation auxiliary device for high and low voltage switchgear. This device allows for easy adjustment of the distance between forklift slot A and forklift slot B, enabling precise matching between the forks and the width of the switchgear slots.

[0030] The present invention will be further explained below with reference to specific embodiments.

[0031] like Figures 1-5 As shown, this embodiment provides an installation auxiliary device for high and low voltage switchgear, including a frame 3. A support plate A1 and a support plate B2 are fitted and slidably mounted on the upper surface of the frame 3. Forklift slots A6 and B7 are longitudinally connected on both support plates A1 and B2. Both support plates A1 and B2 can be independently adjusted horizontally, causing the forklift slots A6 and B7 to shift, thus adjusting the distance between them. This auxiliary structure facilitates the adjustment of the distance between forklift slots A and B, ensuring precise matching between the forks and the width of the switchgear's fork slots. This greatly enhances the stability of the cabinet's load-bearing support points, eliminates "distance conflict" and "center of gravity misalignment" problems between the forks and the cabinet's fork slots, and ensures stability during handling.

[0032] In this embodiment, two longitudinal groove beams 12 are arranged longitudinally and symmetrically at both ends of the lower surface of the frame 3 body, and two gravity wheels 4 are symmetrically arranged on each longitudinal groove beam 12. By setting two symmetrical longitudinal groove beams 12 at the bottom of the frame 3, the load-bearing capacity of the entire frame 3 is increased. Two gravity wheels 4 are symmetrically installed on each longitudinal groove beam 12, and the gravity wheels 4 are located at the four corners of the frame 3 to increase the balance and stability of the frame 3.

[0033] In this embodiment, two transverse channel beams 11 are arranged laterally and symmetrically on the lower surface of the frame 3 body, with both ends of the transverse channel beam 11 abutting against the inner side of the longitudinal channel beam 12 body. The transverse channel beam 11 body abutting against the inner side of the longitudinal channel beam 12 body forms a right angle structure with the longitudinal channel beam 12 and the transverse channel beam 11, further enhancing the load-bearing capacity, balance, and stability of the frame 3.

[0034] In this embodiment, the transverse groove beam 11 is located inside the gravity wheel 4. An adjusting screw 9 is fitted and transversely arranged inside the transverse groove beam 11. One end of the adjusting screw 9 is fitted through the longitudinal groove beam 12 and extends to the outside of the frame 3. The transverse groove beam 11 is located inside the gravity wheel 4, which facilitates the installation of the adjusting screw 9 inside the transverse groove beam 11. One end of the adjusting screw 9 is fitted through the longitudinal groove beam 12 and extends to the outside of the frame 3 and is fixed by an adjusting ring 10. The adjusting ring 10 and the adjusting screw 9 are fixed together. The user grasps the adjusting ring 10 and rotates it to drive the adjusting screw 9 to rotate.

[0035] Furthermore, the other end of the adjusting screw 9 is movably fixed within the transverse groove beam 11 via a screw limiting block 13. Several nuts 14 are appropriately fitted onto the adjusting screw 9, and the nuts 14 are respectively fixed to the support plate A1 and support plate B2. The other end of the adjusting screw 9, located within the transverse groove beam 11, is movably fixed within the transverse groove beam 11 via a screw limiting block 13. In this case, the adjusting screw 9 can only rotate forward or backward without displacement. Several nuts 14 are appropriately fitted onto the adjusting screw 9, and the nuts 14 are respectively fixed to the bottom surfaces of support plate A1 and support plate B2. The rotation of the adjusting screw 9 drives the nuts 14 to generate horizontal displacement, thereby achieving horizontal displacement of support plate A1 and support plate B2. This structure is simple, easy to operate, and has low cost.

[0036] In this embodiment, one end of the adjusting screw 9 extends to the outside of the frame 3 and an adjusting ring 10 is provided. The user drives the nut 14 to produce displacement by rotating the adjusting ring 10, and the adjusting ring 10 can be used to fix the switch cabinet with a pull rope.

[0037] In this embodiment, the inner diameters of both forklift slots A6 and B7 are larger than the outer diameter of the forklift forks. This facilitates compatibility with different forklift models and also makes it easier for the forks to enter and exit the forklift.

[0038] In this embodiment, several fixing rings 8 are symmetrically arranged on both sides of the frame 3 body. The fixing rings 8 are used to fix the high and low voltage switchgear. The design of the fixing rings 8 makes it convenient for users to fix medium and large cabinets or for long-distance transportation, thus enhancing the stability of the cabinet during handling.

[0039] In this embodiment, two protective corners 5 are symmetrically arranged on the outer edges of the tray A1 and tray B2, respectively. The protective corners 5 on tray A1 and tray B2 together limit the high and low voltage switchgear. The protective corners in this structure enhance the cabinet's limiting function, prevent the cabinet from sliding during transportation, thus avoiding personal safety hazards and enhancing the cabinet's stability.

[0040] This utility model also provides the operating principle of an installation auxiliary device for high and low voltage switchgear: First, the user adjusts the fork spacing of the fork in the forklift according to the distance between the two cabinet fork slots of the switchgear body. Then, the user adjusts the distance between forklift slots A6 and B7 in the auxiliary device. The user adjusts the distance between forklift slots A6 and B7 by rotating the adjusting ring 10 on the frame 3. The adjusting ring 10 drives the adjusting screw 9 to rotate in either the forward or reverse direction. The rotation of the adjusting screw 9 causes the nut 14 to produce a horizontal displacement, thus fixing the nut 14. Forklift slots A6 and B7 are respectively formed through the lower surfaces of pallet A1 and pallet B2. Pallet A1 is integrally formed with forklift slot A6, and pallet B2 is integrally formed with forklift slot B7. At least one adjusting screw 9 is provided on the lower surface of pallet A1 and pallet B2. Users can rotate the adjusting ring 10 to achieve horizontal displacement of pallet A1 and pallet B2. This improves the handling efficiency of the switchgear, reduces the intensity of manual labor, and improves the stability of the switchgear during handling. Protective corners 5 are symmetrically set on the outer edges of the upper surfaces of pallet A1 and pallet B2. The protective corners 5 are used to limit the sliding of the switchgear, enhance the cabinet's limiting function, and prevent the cabinet from sliding during handling, thus preventing personal safety hazards. At the same time, multiple fixing rings 8 are set on the frame 3, which can be used to fix the cabinet to the pallet by wrapping with ropes, enhancing the stability of the cabinet.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
