Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, and in particular to a distribution switch transport test assembly vehicle with insulation performance and a use method thereof. Background Art

[0002] With the popularization of electricity, electricity has become an indispensable part of people's lives. Correspondingly, the transportation of power equipment has become more common. However, power equipment is generally large in size and is energized. Generally, large equipment is transported by large forklifts. However, large forklifts are heavy and large in size, which are inconvenient to store and transport. Moreover, they are not insulated, which poses a safety hazard when transporting power equipment. In addition, power tests cannot be performed during transportation, and the condition of the equipment cannot be confirmed. At the same time, different types of forklifts are expensive and have poor applicability. When transporting, the forklift has a small contact surface with the items, and small items cannot be transported by the forklift. Another method is to use forklift pallets for transportation, which require the pallets to be loaded and unloaded. Fixed on a forklift, the transportation area is expanded, the cost is low, and the applicability is high, but it also does not have insulation and poses a safety hazard. It is impossible to conduct electrical tests during transportation, and the condition of the equipment cannot be confirmed before placement. Moreover, equipment that is too heavy on the pallet for transportation is prone to breakage, and has low practicality. It requires manpower to lift and move it to a forklift, which is inconvenient to take, and the load-bearing surface is limited. Different types of large equipment are not easy to place well due to different spacings. Moreover, both transportation methods are prone to large shaking when placing and transporting equipment, and the equipment is prone to falling off and shaking. The anti-sway performance is poor, the stability of the equipment during transportation is poor, and it is dangerous, and the safety of the staff is poor. Summary of the invention

[0016] Step 3: Connect with the forklift through the forklift connection device, and the forklift pushes the transport vehicle and the large equipment on it;

The connection rod contacts the decompression platform to form a strong impact force. The impact force causes the decompression platform to drive the decompression rod and the decompression sheet to move, and then the decompression sheet continuously presses the material of the ACF material box during the movement. The ACF material is forced to move to the gap of the box under the impact force. At this time, the connection device performs preliminary decompression and vibration reduction work. When the pressure relief plate cannot move further downward in the ACF material box, the pressure relief platform stops moving downward. When the connecting rod still has a downward impact force, the connecting rod will drive the portal frame to move. At this time, the pressure relief walls on both sides of the portal frame drive the traction bar to move. During the movement, the pressure relief walls and the fixing parts squeeze the second spiral steel in the middle. The second spiral rod therefore generates an upward reaction force to resist deformation. The device can reduce the pressure of a larger impact force and also reduce the pressure and correct the lateral deviation of the device to prevent lateral movement. At the same time, the lower part of the portal frame will squeeze the first spiral rod, which will also generate an upward reaction force to resist deformation. The elastic structure of the lower part of the portal frame can also alleviate the impact force to ensure the safety of equipment and staff. In addition, the device is provided with a first connecting device and a second connecting device. When the pressure relief effect of the second connecting device on the impact force reaches the limit, the first connecting device will perform secondary pressure relief and vibration reduction to achieve a comprehensive and sufficient pressure relief effect to ensure the stability of the transportation process and the safety of the staff.

The lower end surface of the pressure relief platform 12.5 is fixedly connected to two pressure relief rods 12.6. The pressure relief rods 12.6 pass through the upper part of the ACF material box 12.8 and enter the storage box. The bottom end of the pressure relief rod 12.6 is connected to the pressure relief sheet 12.7. The pressure relief sheet 12.7 is arranged inside the ACF material box 12.8. At the same time, the ACF material in the ACF material box 12.8 does not reach the top of the box body, leaving a large gap.

[0032] The lower part of the shell 12.2 of the first connection device 12 is fixedly connected to the first support plate 4, the upper part of the shell 12.2 is connected to the insulator 7, and the connection rod 12.4 is connected to the bottom of the insulator 7.

[0033] The shell 12.2 of the second connection device 13 is fixedly connected to the insulator 7 at the bottom, and is fixedly connected to the placement plate 8 at the top. The connection rod 12.4 is connected to the bottom of the placement plate 8.

[0034] A specific embodiment, when the lifted large equipment is completely placed on the transport vehicle, the placement plate 8 is squeezed instantly, thereby driving the connecting rod 12.4 to move downward, and the connecting rod 12.4 contacts the decompression platform 12.5 to form a strong downward impact force, and then the impact force causes the decompression platform 12.5 to drive the two decompression rods 12.6 to move, and the decompression sheet 12.7 connected to the decompression rod 12.6 also continuously compresses the material of the ACF material box 12.8 during the movement. The ACF material is forced to move to the gap of the box under the impact force. At this time, the connecting device completes the initial decompression and vibration reduction work.

[0035] The upper end edges of both sides of the door-shaped frame 12.10 are fixedly connected to the pressure relief wall 12.11, and the lower surfaces of the pressure relief walls 12.11 on both sides are fixedly connected to the traction strip 12.14, and a fixing piece 12.15 fixedly connected to the inner wall of the shell is provided below the pressure relief wall 12.11, and the traction strip 12.14 is movably connected to the fixing piece 12.15 through an opening on the fixing piece 12.15, and a fastener 12.16 is arranged at the lower position of the fixing piece 12.15, and the fastener 12.16 passes through the traction strip 12.14 for fastening the traction strip, and a second spiral steel 12.17 is arranged on the outer wall of the traction strip 12.14, and the upper end of the second spiral steel 12.17 is connected to the pressure relief wall 12.11, and the lower end is connected to the fixing piece 12.15.

[0037] In another specific embodiment, when the pressure relief sheet 12.7 cannot move further downward in the ACF material box 12.8, the pressure relief platform 12.5 stops moving downward, and the connecting rod 12.4 thereon still has a downward impact force. At this time, the connecting rod 12.4 drives the door frame 12.10 to move. At this time, the pressure relief walls 12.11 on both sides of the door frame 12.10 drive the traction bar 12.14 to move. During the movement, the pressure relief walls 12.11 and the fixing member 12.15 squeeze the second spiral steel 12.17 in the middle, and the second spiral rod 12.17 thus produces an upward reaction. The force can resist deformation, so the device can reduce pressure on greater impact forces, and at the same time, the lateral deviation of the device can also be reduced and corrected to prevent lateral displacement. At the same time, the lower part of the door-type frame 12.10 will also squeeze the first screw rod 12.12, and the first screw rod 12.12 will also produce an upward reaction force to resist deformation.
