Description

Technical Field

[0001] This utility model belongs to the field of refueling technology for acid fracturing trucks, and in particular relates to an automatic refueling device for acid fracturing trucks. Background Technology

[0002] Acid fracturing trucks are specialized vehicles used to inject high-pressure, high-volume fracturing fluid into wells to break up formations and force proppant into fractures. Current fracturing operations involve long construction cycles and high fuel consumption, necessitating refueling of acid fracturing trucks. A search revealed patent application number 202120758476.7, which discloses an automatic refueling device for acid fracturing trucks, comprising a support assembly and a refueling assembly. The support assembly includes a base and a frame, with the frame mounted on top of the base, and the refueling assembly mounted on top of the base. The refueling assembly includes an oil tank, a housing, an oil pump, a baffle plate, a flow meter, an integrated unit, a second solenoid valve, and an oil delivery pipe. The oil tank is located on top of the base.

[0003] However, during actual use, the applicant found that the automatic refueling device only has one oil tank. When the oil in the tank is depleted, the entire automatic refueling device needs to be transferred to a gas station for refueling, which is inconvenient. Furthermore, during this process, it is impossible to continue supplying oil to the acid fracturing truck. Therefore, we propose an automatic refueling device for acid fracturing trucks. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an automatic refueling device for an acid fracturing truck, comprising a base, on which oil tanks are fixedly placed side-by-side on the top. Symmetrical fork slots are provided on the oil tanks. An oil outlet branch pipe is fixedly installed on the lower side wall of the oil tank, and a hand valve is sleeved and fixedly installed on the oil outlet branch pipe. A housing is fixedly connected to the top of the base on the front side of the oil tank. An oil pump is fixedly installed on the lower part of the housing, and a flow meter is fixedly installed on the upper part of the housing. A T-shaped oil pipe is fixedly connected to the rear side of the housing. The two inlet ends of the T-shaped oil pipe are connected to the oil outlet branch pipes on the two oil tanks respectively via connecting oil pipes. The oil outlet end of the T-shaped oil pipe is connected to the oil inlet end of the oil pump. The two outlet ends of the T-shaped oil pipe are each fitted with a solenoid valve one. An integrated part is fixed on the top of the housing by a support column. A refueling branch pipe is fixed on the peripheral wall of the integrated part. A solenoid valve two is fitted on the refueling branch pipe. The integrated part is connected to the outlet end of the flow meter through a connecting pipe. The inlet end of the flow meter is connected to the outlet end of the oil pump through a connecting pipe. Limiting rings are symmetrically fixed to the top of the base on both sides of the oil tank. Limiting slides are symmetrically and elastically connected inside the oil tank by springs. The upper end of the limiting slide extends into the fork slot and is provided with an inclined part. The lower end of the limiting slide is inserted into the limiting ring.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses an automatic refueling device for acid fracturing trucks. With two fuel tanks, it can supply fuel from one tank when the other runs out. The empty tank can be moved separately to a gas station for refueling using a forklift, eliminating the need to move the entire refueling device there, making it more convenient. A limiting slide is installed at the bottom of the fuel tank, and a limiting ring is fixed to the top of the base. When the forks are inserted into the fork slots, the tilting mechanism moves the limiting slide inward, compressing the spring and causing its lower end to move out of the limiting ring. This allows the fuel tank to be lifted and moved smoothly. Alternatively, by placing the fuel tank in the placement groove and removing the forks from the fork slots, the spring force moves the limiting slide outward, automatically inserting its lower end into the limiting ring, thus achieving automatic limiting and locking of the fuel tank for better performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] An automatic refueling device for an acid fracturing truck includes a base 1. Two oil tanks 2 are fixedly placed side-by-side on the top of the base 1. Each oil tank 2 has symmetrically arranged forklift slots 21. By using the two oil tanks, when the oil in one tank is depleted, the other tank can continue supplying oil to the acid fracturing truck. Furthermore, the empty oil tank can be moved separately to a refueling station using a forklift for refueling, eliminating the need to move the entire refueling device to a refueling station for added convenience. An oil outlet branch pipe 22 is fixedly installed on the lower side wall of the oil tank 2, and a hand valve 10 is sleeved and fixedly installed on the oil outlet branch pipe 22. A housing 7 is fixedly connected to the top of the base 1 on the front side of the oil tank 2. An oil pump 71 is fixedly installed at the lower part of the housing 7, and a flow meter 72 is fixedly installed at the upper part of the housing 7. A T-shaped oil pipe 6 is fixedly connected to the rear side of the housing 7. The two oil inlet ends of the T-shaped oil pipe 6 are connected to the oil outlet branch pipes 22 on the two oil tanks 2 respectively through connecting oil pipes 4. The oil outlet end of the T-shaped oil pipe 6 is connected to the oil inlet end of the oil pump 71. A solenoid valve 5 is fixedly fitted on both oil outlet ends of the T-shaped oil pipe 6. An integrated part 9 is fixedly installed on the upper part of the housing 7 through a support column 8. The lower end of the support column 8 is fixedly connected to the top of the housing 7, and the upper end of the support column 8 is fixedly connected to the bottom of the integrated part 9. A refueling branch pipe 91 is fixedly installed on the peripheral wall of the integrated part 9. 1. Three refueling branch pipes 91 are provided, with a solenoid valve 92 fixedly fitted onto each. The integration unit 9 is connected to the oil outlet of the flow meter 72 via a connecting pipe. The oil inlet of the flow meter 72 is connected to the oil outlet of the oil pump 71 via a connecting pipe. In use, the three refueling branch pipes 91 can be connected to the oil tanks of three acid fracturing trucks respectively via oil pipes. By driving the oil pump 71 to rotate, the oil in the oil tank 2 is transported to the flow meter 72 through the oil outlet branch pipe 22, the connecting oil pipe 4, and the T-shaped oil pipe 6, and then transported to the integration unit 9 via the connecting pipe. Finally, the solenoid valve 92 on the required refueling branch pipe 91 is opened by the external controller to refuel the acid fracturing truck. After the oil in tank 2 is depleted, the corresponding solenoid valve 5 on the T-shaped oil pipe 6 connected to it can be closed, and the solenoid valve 5 on the T-shaped oil pipe 6 corresponding to the other oil tank 2 can be opened to continue supplying oil. At this time, the personnel can manually close the hand valve 10 on the oil tank 2 after the oil supply is depleted, and insert the forklift forks into the fork slot 21 on the oil tank 2 to replenish the oil at the mobile oil station. Then, the oil tank 2 after replenishment is transferred back to the base 1 by the forklift, and the oil outlet branch pipe 22 on the oil tank 2 is reconnected to the oil inlet end of the T-shaped oil pipe 6 through the connecting oil pipe 4. Finally, the hand valve 10 on the oil outlet branch pipe 22 is opened to complete the individual replenishment of oil tank 2.

[0023] The top of the base 1 has a placement groove 11, and the oil tank 2 is placed in the placement groove 11. Limiting rings 3 are symmetrically fixedly connected to the top of the base 1 on both sides of the oil tank 2. The inside of the oil tank 2 is symmetrically elastically connected to the limiting slide 12 by springs 14. The lower part of the oil tank 2 is fixedly connected to a guide rod 13. The two ends of the guide rod 13 are respectively movably inserted into the two limiting slides 12 in the oil tank 2. The spring 14 is movably sleeved on the guide rod 13. One end of the spring 14 abuts against the oil tank 2, and the other end of the spring 14 abuts against the base 1. The upper end of the limiting slide 12 extends into the fork slot 21 and is provided with an inclined part 121. When the fork is inserted into the fork slot 21, the limiting slide 12 can be driven to move inward under the action of the inclined part 121, compressing the spring 14 and causing the lower end of the limiting slide 12 to move out of the limiting ring 3. The limiting slide 12 has a rounded corner 122 at the lower corner of the limiting slide 12. The limiting slide 12 slides along the guide groove opened inside the oil tank 2. By setting the limiting slide 12 at the lower part of the oil tank 2 and fixing the limiting ring 3 at the top of the base 1, the limiting slide 12 can be driven to move inward under the action of the inclined part 121 during the process of inserting the forks into the fork slot 21. This causes the limiting slide 12 to compress the spring 14 and move the lower end of the limiting slide 12 out of the limiting ring 3, thereby enabling the oil tank 2 to be lifted and transferred smoothly. By placing the oil tank 2 in the placement groove 11 and moving the forks out of the fork slot 21, the limiting slide 12 can be driven to move outward under the elastic force of the spring 14, so that the lower end of the limiting slide 12 automatically inserts into the limiting ring 3. This achieves automatic limiting and locking of the oil tank 2, resulting in better performance.

[0024] Working Principle: During use, three refueling branch pipes 91 can be connected to the oil tanks of three acid fracturing trucks via oil pipes. The oil pump 71 drives the oil in tank 2 to be transported through the outlet branch pipe 22, connecting oil pipe 4, and T-shaped oil pipe 6 to the flow meter 72, and then through the connecting pipe to the integration unit 9 for integration. Finally, the solenoid valve 92 on the required refueling branch pipe 91 is opened via an external controller to refuel the acid fracturing truck. After the oil in one tank 2 is depleted, the corresponding solenoid valve 5 on the connected T-shaped oil pipe 6 can be closed, and the solenoid valve 5 on the T-shaped oil pipe 6 corresponding to another tank 2 can be opened to continue refueling. At this time, personnel can manually close the hand valve 10 on the depleted tank 2 and insert the forklift forks into the fork slot 21 on the tank 2 to refuel the tank 2 at the mobile refueling station. During the process of inserting the forks into the fork slots 21, the inclined part 121 can drive the limiting slide 12 to move inward, so that the limiting slide 12 compresses the spring 14 and moves the lower end of the limiting slide 12 out of the limiting ring 3, thereby smoothly lifting and transferring the oil tank 2. Then, the oil tank 2 after replenishment is transferred back to the base 1 by the forklift. By placing the oil tank 2 in the placement groove 11 and moving the forks out of the fork slots 21, the limiting slide 12 can be driven to move outward under the elastic force of the spring 14, so that the lower end of the limiting slide 12 automatically inserts into the limiting ring 3, realizing automatic limiting and locking of the oil tank 2. Then, the oil outlet branch pipe 22 on the oil tank 2 is reconnected to the oil inlet end of the T-shaped oil pipe 6 through the connecting oil pipe 4. Finally, the hand valve 10 on the oil outlet branch pipe 22 is opened to complete the individual replenishment of the oil tank 2.
