Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, and in particular to a mother-daughter type bearing platform. Background Technology

[0002] The high-voltage withstand voltage tester consists of an operating platform and a transformer, which are two separate units that require a cable connection for use. Since the operating platform and transformer themselves cannot be moved, they need to be transported using a cart or pallet, but this still requires manual handling. Currently, the operating platform, transformer, and all other testing equipment are moved together on a wheeled trailer. Upon arrival at the testing area, they are unloaded one by one and placed in their respective positions. The transformer is heavy and difficult to move, especially when transporting it between different workstations and locations.

[0003] The existing transportation methods have the following problems: it is inconvenient to move transformers within a small area, and they can only be moved manually; the transportation between different work stations and sites requires frequent bending over to place and load transformers, which can cause labor injuries to operators. This method of loading and unloading is not convenient enough. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model discloses a mother-and-child type support platform, comprising a track base plate 1, a loading / unloading tail plate 2, and a brake tray 3. The track base plate 1 and the loading / unloading tail plate 2 are mounted on the brake tray 3. The loading / unloading tail plate 2 includes a base plate 4, with two side plates 5 in the middle of the base plate 4. A clamping plate 6, a pull ring 7, and a connecting plate 8 are provided between the two side plates 5. Two pins 10 are provided between the clamping plate 6 and the connecting plate 8, and springs 9 are fitted on the pins 10. The track base plate 1 has a locking hole 13. The track base plate 1 also has a back reinforcing rib 14. The brake tray 3 includes a tray base plate 11 and brake casters 12. There are four brake casters 12, located at the four corners of the bottom of the tray base plate 11. The track base plate 1 is fixedly connected to an external carrier. The loading / unloading tail plate 2 has triangular folded edges on both sides.

[0023] During use, for the withstand voltage test, move the carrier to the product under test; the transformer is located in the mother-type support platform and needs to be unloaded from the carrier; pull the pull ring 7 on the loading and unloading tail plate 2 upwards, the pin 10 disengages from the pin locking hole 13 of the track base plate 1, and lay the loading and unloading tail plate 2 flat; push the transformer along the track to the ground to complete the unloading action. Figure 7 After the withstand voltage test is completed, repeat the above steps to return the transformer to its original position on the vehicle.

[0024] Example:

[0025] This embodiment addresses the difficulties encountered during the transport of transformers for withstand voltage testing instruments, such as the challenges of loading and unloading, and the labor-intensive handling required. Considering the large weight of the transformer and the need for movement within a limited area, a mother-daughter type support platform is constructed. This platform is positioned at the bottom of the carrier, with a sunken design 25mm above the ground. This prevents the carrier from hitting the ground during movement while ensuring sufficient effort for loading and unloading the transformer. The mother-daughter type support platform consists of a track base plate, a loading / unloading tail plate, and a braking tray, allowing for both combined and separated configurations of the transformer and carrier (e.g., ...). Figure 1 , 2 Typically, when the transformer is being transported or parked and not in use, it is mounted on the vehicle and combined with the carrier. When a withstand voltage test is being performed, the transformer is removed from the vehicle and separated from the carrier.

[0026] The mother-daughter type support platform is located on the bottom of the workstation and is fixed to the vehicle frame by welding and bolting. It is lower than the vehicle's base plate but slightly higher than the ground (approximately 25mm), ensuring the workstation's mobility during movement and preventing it from hitting the ground. The track base plate is formed by bending a 4mm steel plate into an "arch" shape, with reinforcing ribs welded to the back to ensure load-bearing strength (e.g., ...). Figure 3 The loading / unloading tailgate is fixed to the carrier by welding. The bottom plate is formed by bending a 4mm steel plate, with triangular edges, and serves as a support leg when the loading / unloading tailgate is laid flat on the ground (e.g., ...). Figure 5The brake tray is specially designed for the shape of the transformer and is used in conjunction with the track base plate and loading / unloading tail plate. It is a carrier for transporting transformers. The tray base plate is made of 4mm steel plate bent into shape and is equipped with 4 brake casters (e.g., Figure 6 The transformer is bolted to the base plate of the pallet, allowing for easy loading and unloading, flexible turning, and stopping at any position. The transformer always rests on the brake tray, and its movement relies entirely on the four casters of the brake tray. When the loading / unloading tailplate is lowered, it forms an angle of approximately 5° with the ground, creating a small ramp between the vehicle and the ground (25mm height difference), allowing the transformer to be easily pushed up and down. This is the working principle of the mother-daughter type load-bearing platform, enabling the transformer to easily load and unload. A spring-loaded locking mechanism is installed on the loading / unloading tailplate. Its function is to lock the tailplate when it is retracted, firmly securing it to the vehicle, and simultaneously preventing the transformer from slipping off the track base plate during vehicle movement. (The spring-loaded locking mechanism is shown in the image.) Figure 5 The device consists of left and right side plates, a clamping plate, a pull ring, a connecting plate, a pin, and a spring. The left and right side plates and clamping plate are welded and fixed to the loading and unloading tail plate. The pull ring, connecting plate, pin, and spring are bolted into the slots of the clamping plate. To ensure smooth up and down sliding, grease can be applied to the moving parts. To unlock, pull up the pull ring; the pin disengages from the lock hole, and the loading and unloading tail plate can be laid down. To retract, pull up the pull ring and stand the loading and unloading tail plate upright, release the pull ring, the pin inserts into the lock hole, and the tail plate is fixed and reset (e.g., ...). Figure 7 ).

[0027] This invention facilitates the movement of the transformer in a withstand voltage tester within a small range, making its movement more flexible and efficient; it also makes loading and unloading easier and less strenuous; and it facilitates securing the transformer during transport, preventing it from shaking and falling. This invention features a stable and reliable structure with strong load-bearing capacity; it significantly reduces labor intensity, is highly convenient to use, and saves effort; it prevents falls, making transformer transport safer; and it saves operating time and improves work efficiency.
