Description

Technical Field

[0001] This utility model belongs to the field of gas cylinder transportation technology, specifically relating to a gas cylinder handling vehicle. Background Technology

[0002] Standardized gas replenishment operations for primary equipment insulated with sulfur hexafluoride (SF6) gas require the gas cylinder to be located close to the primary equipment and the pipeline to be flushed and replenished. Because SF6 cylinders are heavy—the commonly used 50-liter cylinder weighs 60 kilograms—at least four people are generally required to complete the loading, unloading, and handling. Improper coordination can lead to cylinders falling and injuring personnel, and the process is time-consuming, labor-intensive, and poses safety risks. Utility Model Content

[0003] The purpose of this utility model is to provide a gas cylinder transport vehicle to solve the problem of inconvenient gas cylinder transport, reduce the labor intensity of workers, and reduce safety hazards.

[0004] This utility model is implemented by the following technical solution:

[0005] A gas cylinder transport vehicle includes a frame body; a support plate is vertically mounted on the bottom end of the main support rod of the frame body, and a limit plate is mounted on the front side of the support plate; a reinforcing rod is mounted on the back of the center of the load-bearing frame of the frame body, and the bottom end of the reinforcing rod is connected to the support plate; a telescopic rod is mounted on the reinforcing rod, the bottom end of the telescopic rod is mounted on the support plate, a universal joint is fixed to the top end of the telescopic rod, a steel plate is fixed to the end of the universal joint away from the telescopic rod, and a clamp is mounted on the steel plate, the size of the clamp being adapted to the gas cylinder. The displacement of the clamp can be achieved by extending and retracting the telescopic rod, facilitating the movement of the gas cylinder along the length of the telescopic rod after it is clamped by the clamp. During loading and unloading, the worker only needs to gently push the gas cylinder, which causes the clamp and the steel plate to rotate, and the universal joint to rotate accordingly until the desired angle is reached. The weighing fulcrum of the gas cylinder is on the steel plate, i.e., supported by the telescopic rod, so the worker does not need to exert too much force to flip the gas cylinder. During transportation, the clamp and the limiting plate work together to fix the gas cylinder.

[0006] Furthermore, a cushioning pad is provided inside the pallet. This cushions the gas cylinders and prevents them from bumping into each other during loading, unloading, and handling.

[0007] Furthermore, the main body of the vehicle frame includes two parallel main support rods, and at least two load-bearing frames are arranged parallel between the two main support rods. The two ends of the load-bearing frames are respectively fixed to the two main support rods, and the curvature of the load-bearing frames is adapted to the gas cylinder. A front wheel is provided at the lower part of the main support rods. A rear wheel support frame is hinged to the upper part of the main support rods, and a rear wheel is provided at the bottom end of the rear wheel support frame. An adjustment bracket is provided between the rear wheel support frame and the main support rods.

[0008] Furthermore, a heating plate is provided on the support frame. The heating plate is an arc-shaped plate, and its size is adapted to the gas cylinder. The liquefaction temperature of SF6 gas is approximately -25℃ at a pressure of 0.5MPa and approximately 0℃ at a pressure of 1.0MPa. Therefore, to prevent SF6 liquefaction from failing to replenish properly in extremely cold weather, a heating plate is provided on the support frame. This allows the heating plate to transfer heat to the gas cylinder during transportation, keeping the cylinder temperature above the liquefaction temperature.

[0009] Furthermore, a handle is provided at the top of the main support rod.

[0010] Beneficial effects:

[0011] This utility model provides a gas cylinder transport vehicle. By using a telescopic rod in conjunction with accessories such as universal joints and clamps, gas cylinders can be lifted, fixed, and flipped, facilitating the loading, unloading, and transportation of gas cylinders. Using the transport vehicle during transportation reduces the number of personnel, saves time and costs, and avoids personnel injuries caused by improper loading, unloading, and transportation of gas cylinders, thus improving the safety of personnel.

[0028] A type of gas cylinder transport vehicle, such as Figure 1-6As shown, it includes a frame body 10, which includes two parallel main support rods 11, each with a handle 12 at its top. Three support frames 13 are arranged parallel to each other between the two main support rods 11, with both ends of each support frame 13 fixed to the two main support rods 11, and the curvature of the support frame 13 is adapted to the gas cylinder 40. A front wheel 16 is located at the lower part of the main support rods 11. A rear wheel support frame 17 is hinged to the upper part of the main support rods 11, and a rear wheel 18 is located at the bottom of the rear wheel support frame 17. In this embodiment, the rear wheel... 18 is a universal caster with brakes. An adjustable bracket 19 is provided between the rear wheel support frame 17 and the main support rod. The adjustable bracket 19 includes two steel rods that are hinged to each other. The ends of the two steel rods that are away from each other are respectively hinged to the main support rod 11 and the rear wheel support frame 17. When the two steel rods are on the same straight line, the length of the adjustable bracket 19 is the farthest distance that the main support rod 11 and the rear wheel support frame 17 can be extended. This can prevent them from being extended too far or even splitting apart. The adjustable bracket 19, the main support rod 11, and the rear wheel support frame 17 form a stable triangular structure.

[0029] A support plate 20 is vertically installed at the bottom of the main support rod 11. The width of the support plate 20 is greater than the diameter of the gas cylinder 40. A limit plate 21 is installed on the front side of the support plate 20, and a buffer pad 22 is installed inside the support plate 20. A reinforcing rod 15 is welded to the back of the center of multiple support frames 13, and the bottom end of the reinforcing rod 15 is welded to the support plate 20. A telescopic rod 30 is provided on the reinforcing rod 15. The telescopic rod 30 is an electro-hydraulic telescopic rod and also includes a remote control that is signal-connected to the telescopic rod 30. The telescopic rod 30 can be welded to the side wall of the reinforcing rod 15 or tied to the reinforcing rod 15. The bottom end of the telescopic rod 15 is set on the support plate 20. A universal joint 31 is fixed to the top end of the telescopic rod 30. A steel plate 32 is fixed to the end of the universal joint 31 away from the telescopic rod 30. A clamp 33 is provided on the steel plate 32. In this embodiment, the clamp 33 is a clamp for accumulators. The mounting base of the clamp 33 is fixed to the steel plate 32 by bolt structure. The body of the clamp 33 is located between the two main support rods 11. The size of the clamp 33 is adapted to the gas cylinder 40.

[0030] A heating plate 14 is mounted on the support frame 13. The heating plate 14 is an arc-shaped plate, the size of which is adapted to the gas cylinder. The heating plate is made of aluminum alloy and contains multiple heating wires (nickel-chromium alloy resistance wires) covered with mica sheets. A storage bracket 113 is mounted on one of the main support rods. The storage bracket 113 is equipped with a temperature controller 114 and a power supply 115. The temperature controller 114 can adjust the temperature of the heating plate 14 and has a display screen to display the temperature data. The power supply 115 supplies power to the heating plate 14 and the telescopic rod 30. The relevant wiring diagram is not shown.

[0031] Before replenishing SF6, the moisture content in cylinder 40 needs to be tested. Replenishment can only proceed if the moisture content is within acceptable limits. Currently, purchased cylinders are typically stored and tested every six months. Therefore, this application also includes a pressure gauge 111 and an SF6 density micro-moisture sensor 112 on the main support rod 11. The SF6 density micro-moisture sensor 112 is connected to a signal display screen to show micro-moisture data. This allows the cylinder 40 to be placed on a transport vehicle to test the moisture content. Once the moisture content is within acceptable limits, it can be pushed to the replenishment area. In addition, to avoid the safety risk of increased pressure, the pressure gauge 111 can also be used to test the pressure before pushing the cylinder to the replenishment area. A bracket can be installed on the top of one of the main support rods 11, and a three-way valve is placed on the bracket. When testing is required, remove the safety cap of the gas cylinder 40, connect one end of the three-way valve to the valve of the gas cylinder 40, connect the other end to the pressure gauge 111 or the SF6 density micro-moisture sensor 112, and seal the third end to start testing. After testing, disconnect the connection and put the safety cap back on. When gas replenishment is required, connect one end of the three-way valve to the valve of the gas cylinder 40, seal the other end, and connect the third end to the gas replenishment pipe to replenish gas.

[0032] When using, first place the pallet truck next to the gas cylinder to be transported, and tilt the pallet truck so that the pallet 20 contacts the ground. Figure 6 Move the gas cylinder to be transported onto the buffer pad 22 of the pallet 20, adjust the clamp 33 to tightly clamp the gas cylinder 40, so that the gas cylinder 40 is fixed on the transport vehicle under the action of the clamp 33 and the limiting plate 21, then tilt the transport vehicle and unfold the adjusting bracket 19 so that the main support rod 11 and the rear wheel support frame 17 remain relatively stationary, at which time the front wheel 16 and the rear wheel 18 are both in contact with the ground. Figure 7 The staff pushes the transport vehicle to the refueling area. Upon arrival, the rear wheels 18 are braked to begin refueling. When loading and unloading the gas cylinder 40 onto the transport vehicle, since the vehicle's cargo bed is much higher than the ground (at least 30 cm above the ground), the telescopic rod 30 is controlled by a remote control to raise the clamp 33. Due to the high friction on the inner side of the clamp 33, it can lift the gas cylinder 40 along with it until the height of the clamp 33 is slightly higher than the height of the cargo bed and the bottom of the gas cylinder 40 is higher than the limit plate 21. Figure 8 Then, two workers work together to manually rotate the gas cylinder 40, causing it to flip over with the support of the telescopic rod 30, universal joint 31, and steel plate 32, until the bottom of the gas cylinder 40 is slightly higher than the height of the truck bed. Figure 9 Lift the gas cylinder 40 onto the truck bed and then loosen the clamp 33. Additionally, when no work is required, the adjusting bracket 19 can be folded up to allow the transport vehicle to be stored and carried easily.

[0033] The successful development of the portable air replenishment transport vehicle has the following benefits:

[0034] 1) Reduced costs: Before the application, at least four people were needed for loading and unloading gas cylinders and multi-interval gas replenishment operations in substations. After the application, only two people are needed, which frees up labor and saves labor costs.

[0035] 2) Time efficiency: After application, it effectively solved the problem of difficult loading, unloading and transportation of gas cylinders during gas replenishment operations, reduced the labor intensity of maintenance personnel and reduced the time of gas replenishment operations.

[0036] 3) Safety benefits: It avoids personnel injuries caused by improper loading, unloading and handling of gas cylinders, and improves the safety of staff.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
