Description

Technical Field

[0001] The present application relates to the technical field of functional vehicles, and in particular to a multifunctional vehicle for installing a high-voltage cabinet transformer. Background Art

[0002] High-voltage cabinet transformers are mainly used to convert high voltage into low voltage or high current into low current, which is convenient for measurement, protection and use. This conversion isolates secondary equipment such as measuring instruments and relays from high voltage, thus ensuring personal safety.

[0003] At present, the transformer is mainly installed in the cabinet by manual lifting. However, due to the large weight of the transformer, multiple people are usually required to work. However, due to the limited installation space inside the cabinet, not only the construction is restricted, but also time-consuming and labor-intensive. The existing installation auxiliary tool in the same field is an electric robotic arm, but because the robotic arm needs to be fixed on the foundation as a support point, its construction range is fixed. Therefore, the high-voltage cabinet can only be frequently transported to realize the transformer installation operation, which not only limits the improvement of installation efficiency, but also makes it very easy for the cabinet to be bumped during transportation, causing its internal distribution components to loosen. Utility Model Content

[0004] The problem to be solved by the present application is that the existing mutual inductors have a large deadweight. When a fixedly arranged mechanical arm is used to replace manual lifting for installation, the high-voltage cabinet needs to be frequently transported due to its fixed construction range.

[0005] In order to solve the above-mentioned technical problems, the present application provides a multi-functional vehicle for installing a high-voltage cabinet transformer, including a frame for serving as a basic support, casters for walking are arranged at the bottom of the frame, a table arranged horizontally with the frame and capable of being raised and lowered in a vertical direction is arranged directly above the frame, a lifting assembly capable of driving the table to be raised and lowered is arranged between the frame and the table, a flippable frame rod for fixing the transformer is arranged on one side of the table, and a support arm assembly is provided at the bottom of the table that can both support the frame rod and be folded and stored.

[0006] Since the multi-functional vehicle of the present application is designed with a lifting assembly, a rack and an arm assembly, the vertical lifting operation of the transformer can be realized through the lifting assembly, the horizontal movement operation of the transformer can be realized through the arm assembly, and the spatial flipping operation of the transformer can be realized through the rack. At the same time, the casters can also facilitate the spatial movement of the multi-functional vehicle, thereby solving the problem that the transformer in the prior art has a large dead weight and when a fixedly arranged mechanical arm is used instead of manual lifting for installation operation, the high-voltage cabinet needs to be frequently transported due to its fixed construction range.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0019] The present application relates to a multifunctional vehicle for installing a high-voltage cabinet transformer, such as Figure 1-11As shown, the functional vehicle includes a frame 5 for supporting the foundation, casters 4 for walking are arranged at the bottom of the frame 5, a table 6 is arranged horizontally with the frame 5 and can be raised and lowered in the vertical direction, and a lifting component 3 capable of driving the table 6 to rise and fall is arranged between the frame 5 and the table 6. In order to facilitate the installation operation deep inside the high-voltage cabinet, a flippable rack 9 for fixing the transformer 8 is arranged on one side of the table 6. Due to the different types of transformers 8, the installation depths inside the cabinet are also different. Therefore, a support arm component 7 is added to the lower part of the table 6, which can both support the rack 9 and be folded for storage.

[0020] The lifting assembly 3 includes a telescopic motor 11 and a support plate 10. The number of the support plates 10 is at least one group, and each group of support plates 10 has two support plates 10, which are symmetrically cross-arranged. The support plates 10 are hinged to each other at the center points. The bottom end of one of the support plates 10 can slide back and forth in the horizontal direction of the frame 5, and the top end of the other support plate 10 can slide back and forth in the horizontal direction of the table 6, so that a stable parallelogram can be formed between the four end points of the two support plates 10, thereby realizing the stable lifting operation of the table 6. A telescopic motor 11 for providing driving force is also arranged on the upper part of the support plate 10, so that the support plate 10 can drive the table 6 to perform a stable vertical lifting operation with the help of a point-dynamic telescopic operation.

[0021] The support arm assembly 7 includes an arm rod 12, and there are multiple arm rods 12, which are connected to each other by a damping shaft. The arm rod 12 at one end is fixedly connected to the table plate 6, and the arm rod 12 at the other end is connected to the frame rod 9 by a damping shaft. The extendable arm rod 12 is used to extend the depth of the frame rod 9 into the cabinet to meet the installation requirements of the transformer 8. In order to achieve effective storage of the arm rod 12, the lengths of the arm rods 12 are not equal. The length ratio of the arm rods 12 from short to long is 1:1.59:5.05:12.49, so that the arm rod 12 can not only achieve the expansion of the installation depth, but also be completely stored under the table plate 6.

[0022] A control box 2 is also arranged at one end of the upper part of the frame 5. In order to prevent the center of gravity of the frame 5 from overturning due to a large change after the support arm assembly 7 carrying the mutual inductor 8 is unfolded, a counterweight block 15 is added at the lower part of the interior of the control box 2 to stabilize the center of gravity of the frame 5, and a plurality of battery packs 14 electrically connected to the telescopic motor 11 are arranged on the upper part of the counterweight block 15. In addition, a motor controller 13 for controlling the telescopic motor 11 is added to the interior of the control box 2. In order to facilitate the operation of the telescopic motor 11, a main switch 16 and a charging port 17 are arranged on the upper part of the side wall of the control box 2, and a power display 18 and an emergency stop switch 19 are arranged on the top of the control box 2. An armrest 1 is also arranged on one side of the control box 2.

[0023] Due to the difference in the two installation positions of the cabinet, namely, hoisting and rear installation, the orientation angle of the transformer 8 is different. At this time, the frame rod 9 needs to be rotated around the arm rod 12 with the help of the damping shaft, so as to switch between the horizontal or vertical states. In order to keep the frame rod 9 relatively stable in the vertical state to avoid accidental falling due to the gravity of the transformer 8, a detachable limit connecting piece 20 is added between the frame rod 9 and the arm rod 12, and a pin shaft 21 adapted thereto is formed on the upper part of the frame rod 9 and the arm rod 12, so that the frame rod 9 is limited from rotating circumferentially around the arm rod 12 by means of the limit connecting piece 20 and the pin shaft 21 being sleeved together.

[0024] Since the distance between the two pins 21 will change before and after the rack rod 9 is flipped, three holes are formed on the upper part of the limiting connecting piece 20, one of which is used to be socketed with the pin 21 of the rack rod 9, and the other two holes are used to be socketed with the pin 21 of the arm rod 12 in different states.

[0025] When in use, first select the direction of the rack rod 9 according to the installation form of the mutual inductor 8. When the mutual inductor 8 is hoisted, the rack rod 9 is arranged horizontally. When the mutual inductor 8 is installed laterally, the rack rod 9 is arranged vertically. Then, the telescopic motor 11 drives the support plate 10 to drive the table 6 to rise. When the telescopic motor 11 is extended, the motor will be locked. Only by controlling the motor reversal can the motor be shortened to prevent the table 6 from falling suddenly when the battery is insufficient. Then, manually pull out the arm 12 and adjust the direction of the rack rod 9. Install the limit connecting piece 20 to achieve the circumferential limit between the rack rod 9 and the arm 12, and then the mutual inductor can be 8 is pre-installed on the upper part of the frame rod 9, and then the frame 5 can be moved in space with the help of casters 4. After moving to the front of the cabinet, the numerical height of the table plate 6 is adjusted according to the installation position. The horizontal direction is adjusted by adjusting the extension angle of the arm rod 12 so that the mutual inductor 8 can be aligned with the screw hole position, and then the bolt tightening operation of the mutual inductor 8 can be performed manually, thereby using a movable multi-functional vehicle to replace manual lifting and fixed mechanical arms, which can not only reduce the intensity of manual labor, but also avoid the transportation collision of the cabinet, especially when the cabinet is installed in batches, the installation efficiency is more significantly improved.
