Technical Field
[0001] The utility model relates to the technical field of refueling vehicles, in particular to a lifting pipe rack for the underground well hose of a pipeline refueling vehicle. Background Technique
[0002] Pipeline refueling vehicles are mainly used in large airports with underground refueling pipelines to refuel large, medium and small aircraft. The refueling vehicle chassis is equipped with an underground well hose. During operation, the operator takes out the underground well hose from the hose support on the chassis, holds the refueling connector at the front end of the underground well hose by hand, and drags the underground well hose to the underground well socket for docking. After the operation is completed, the hose is retracted, and the underground well hose is lifted onto the hose support and fixed.
[0003] Manually fixing the underground well hose on the hose support or removing the underground well hose from the hose support is time-consuming and laborious, very inconvenient to operate, and has low work efficiency. And generally, the existing hose support is formed by bending a round pipe and then fixed around the outside of the whole vehicle. After fixing the underground well hose, the length of the whole vehicle is very long, and the departure angle of the rear wheels of the vehicle body is very small, resulting in poor downhill passability of the refueling vehicle. Content of the Utility Model
[0004] To solve the above-mentioned deficiencies of the prior art, the utility model provides a lifting pipe rack for the underground well hose of a pipeline refueling vehicle, which does not additionally increase the length of the whole vehicle and realizes the automatic retraction and extension of the underground well hose on the pipe rack, improving the operation efficiency.
[0005] The technical solution of the utility model is: a lifting pipe rack for the underground well hose of a pipeline refueling vehicle, including a main frame body. The main frame body is composed of a first support and a second support located on both sides of the bottom of the vehicle body. A plurality of movable hanging racks for fixing the underground well hose are arranged on the first support and the second support along the length direction. The top of the movable hanging rack is connected to the first support / second support through a hook, and a caster is installed at the bottom of the movable hanging rack. The first support and the second support are connected to the vehicle body through a lifting mechanism. The main frame body has a first state in which the casters of the movable hanging rack move to a certain height above the ground under the drive of the lifting mechanism, and a second state in which the hook of the movable hanging rack disengages from the first support / second support. A limit sensor for detecting the main frame body in the first state and the second state is arranged on the lifting mechanism. By installing the main frame body in a split manner on both sides of the bottom of the vehicle body, the main frame body will not increase the length of the whole vehicle in the length direction of the vehicle body, and thus the departure angle of the rear wheels of the vehicle body will not decrease, ensuring the downhill passability of the refueling vehicle. At the same time, the main frame body moves to the first state and the second state respectively under the cooperation of the lifting mechanism and the limit sensor, completing the lifting and disengaging operations of the movable hanging rack. The operator can directly drag the underground well hose in the direction close to or away from the main frame body to complete the retraction and extension operations of the underground well hose, effectively reducing the labor intensity and improving the operation efficiency.
[0006] There are at least two lifting mechanisms on the first bracket / second bracket, which are respectively located inside both ends of the first bracket / second bracket.
[0007] The lifting mechanism is a lifting cylinder. The end of the cylinder body of the lifting cylinder is fixedly installed at the bottom of the vehicle body. The output end of the lifting cylinder is arranged vertically and is fixedly connected to the corresponding first bracket and second bracket through a connecting frame.
[0008] The first bracket is located on the side of the vehicle body bottom away from the oil pipeline, and the second bracket is located on the side of the vehicle body bottom close to the oil pipeline. A joint bracket for placing the front end of the underground well hose, i.e., the fuel filling joint, is fixed at one end of the first bracket close to the vehicle head.
[0009] The limit sensor includes an upper proximity switch and a lower proximity switch that are vertically distributed and move together with the output end of the lifting cylinder. The upper proximity switch is disengaged from the outer wall of the cylinder body of the lifting cylinder to form a detection signal when the main frame body is in the second state. The lower proximity switch cooperates with the outer wall of the cylinder body of the lifting cylinder to form a detection signal when the main frame body is in the first state.
[0010] The connecting frames at the ends of the first bracket and the second bracket away from the vehicle head are connected by a transverse connecting rod.
[0011] Both the first bracket and the second bracket are pipes with a rectangular cross-section, and the first bracket and the second bracket are divided into a straight pipe section and an arc section along the direction away from the vehicle head.
[0012] The first bracket and the second bracket are formed by bending rectangular pipes, which can ensure the overall stiffness and strength of the main frame body.
[0013] The beneficial effects of the present utility model are as follows: In this solution, the main frame body is installed on both sides of the vehicle body bottom in a split manner, and the main frame body will not increase the overall length of the vehicle in the vehicle body length direction. Furthermore, the departure angle of the rear wheels of the vehicle body will not decrease, ensuring the downhill passability of the fuel tanker. At the same time, under the cooperation of the lifting mechanism and the limit sensor, the main frame body moves to the first state and the second state respectively to complete the lifting and disengagement operations of the mobile hanging rack. The operator can directly drag the underground well hose along the direction close to or away from the main frame body to complete the retraction and extension operations of the underground well hose, effectively reducing the labor intensity and improving the operation efficiency.

Detailed implementation manners
[0020] To enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1-4 shown, the present utility model provides a lifting pipe rack for the underground well hose of a pipeline refueling vehicle, which includes a main frame body. The main frame body is composed of a first bracket 1 and a second bracket 2 located on both sides of the vehicle body bottom. In this embodiment, the first bracket 1 is located on the side of the vehicle body bottom far from the oil pipeline 10, and the second bracket 2 is located on the side of the vehicle body bottom close to the oil pipeline 10. By installing the main frame body in a split manner on both sides of the vehicle body bottom, it will not cause an increase in the overall vehicle length in the vehicle body length direction, and thus the departure angle of the rear wheels of the vehicle body will not decrease, ensuring the downhill passing performance of the refueling vehicle; to ensure that the main frame body has sufficient strength and stiffness, both the first bracket 1 and the second bracket 2 are pipes with a rectangular cross-section. Further preferably, in order to make the first bracket 1 and the second bracket 2 fit the vehicle body structure, the first bracket 1 and the second bracket 2 are divided into a straight pipe section and an arc section along the direction away from the vehicle head.
[0022] A plurality of movable hanging brackets 3 for fixing the underground well hose 8 are provided on the first bracket 1 and the second bracket 2 along the length direction. The top of the movable hanging bracket 3 is connected to the first bracket 1 / second bracket 2 through a hook 301, and a caster 302 is installed at the bottom of the movable hanging bracket 3. Specifically in this embodiment, as Figure 5As shown in the figure, the movable hanger 3 is composed of pipe clamps and fastening bolts 305. The pipe clamps include an upper clamping plate 303 and a lower clamping plate 304 which are butt-jointed. Semi-circular holes are provided on the butting surfaces of the upper clamping plate 303 and the lower clamping plate 304. The two semi-circular holes are butted to form a through hole for fixing the well pipe 8. There are two fastening bolts 305, which are symmetrically distributed on both sides of the semi-circular hole. They sequentially penetrate through the upper clamping plate 303 and the lower clamping plate 304 and are connected to nuts to realize the butt-joint fixation of the upper clamping plate 303 and the lower clamping plate 304. The hook 301 and the caster 302 are respectively fixedly installed at the top of the upper clamping plate 303 and the bottom of the lower clamping plate 304.
[0023] The first bracket 1 and the second bracket 2 are connected to the vehicle body through a lifting mechanism. The main frame body has a first state in which it moves to a certain height above the ground with the caster 302 of the movable hanger 3 off the ground under the drive of the lifting mechanism, and a second state in which it moves to the hook 301 of the movable hanger 3 off the first bracket 1 / second bracket 2. The lifting mechanism is provided with limit sensors for detecting the main frame body in the first state and the second state. With the cooperation of the lifting mechanism and the limit sensors, the main frame body moves to the first state and the second state respectively, corresponding to the completion of the lifting and detachment operations of the movable hanger 3. The operator can directly drag the well pipe 8 in the direction close to or away from the main frame body to complete the winding and unwinding operations of the well pipe 8, effectively reducing the labor intensity and improving the operation efficiency.
[0024] To ensure that the well pipe 8 is stably suspended on the main frame body, a joint bracket 4 for placing the front end of the well pipe 8, namely the fuel filling joint 9, is fixed at one end of the first bracket 1 close to the oil pipeline 10. Preferably, the joint bracket 4 has a support frame that matches the fuel filling joint 9, and the outside of the support frame is welded and fixed to the first bracket 1 through a connecting plate.
[0025] Further preferably, to ensure the stability of the main frame body during the lifting process, there are at least two lifting mechanisms on the first bracket 1 / second bracket 2, which are respectively located inside both ends of the first bracket 1 / second bracket 2. For example, Figure 1 in this embodiment, the number of lifting mechanisms is two. If there are more than two, they can be arranged at the middle position of the first bracket 1 / second bracket 2.
[0026] The lifting mechanism is a lifting cylinder 5. In this embodiment, the lifting cylinder 5 uses hydraulic lifting. In other embodiments, the lifting cylinder 5 can also use electric lifting. The end of the cylinder body of the lifting cylinder 5 is fixedly installed at the bottom of the vehicle body. The output end of the lifting cylinder 5 is arranged vertically and is fixedly connected to the corresponding first bracket 1 and second bracket 2 through a connecting frame 6. Specifically, the connecting frame 6 is an L-shaped bracket. The end face of the horizontal section of the connecting frame 6 is welded to the inside of the first bracket 1 / second bracket 2. A connecting ear plate is welded to the end face of the vertical section of the connecting frame 6, and the connecting ear plate is fixed to the output end of the lifting cylinder 5 through bolts.
[0027] As Figure 5 shown, the limit sensor includes an upper proximity switch 12 and a lower proximity switch 13 that are vertically distributed and move together with the output end of the lifting cylinder 5. The upper proximity switch 12 is disengaged from the outer wall of the cylinder body of the lifting cylinder 5 to form a detection signal when the main frame is in the second state. The lower proximity switch 13 cooperates with the outer wall of the cylinder body of the lifting cylinder 5 to form a detection signal when the main frame is in the first state. In this embodiment, the limit sensor is located inside the arc section of the first bracket 1 (i.e., the end far from the vehicle head). Specifically, a mounting plate is welded to the vertical section of the connecting frame 6 at this position. The upper proximity switch 12 and the lower proximity switch 13 are respectively fixedly installed at the upper and lower ends of the mounting plate 11, so as to move synchronously with the output end of the lifting cylinder 5. As Figure 3 shown, as the output end of the lifting cylinder 5 descends, it drives the connecting frame 6 and the mounting plate 11 to move downward together. When the upper proximity switch 12 is disengaged from the outer side of the cylinder body of the lifting cylinder 5, the lifting cylinder 5 is controlled to stop descending. At this time, the main frame is in the second state. As Figure 1 shown, as the output end of the lifting cylinder 5 ascends, it drives the connecting frame 6 and the mounting plate 11 to move upward together. When the lower proximity switch 13 forms an induction with the outer side of the cylinder body of the lifting cylinder 5, the lifting cylinder 5 is controlled to stop ascending. At this time, the main frame is in the first state.
[0028] To enhance the stability of the entire main frame and reduce the shaking of the main frame during the driving of the refueling vehicle, the connecting frames 6 (i.e., the connecting frames 6 located at the arc section) at the ends of the first bracket 1 and the second bracket 2 far from the vehicle head are connected by a transverse link 7. In this embodiment, the two ends of the transverse link 7 are respectively welded and fixed to the surfaces of the vertical sections of the corresponding two connecting frames 6.
[0029] When implementing this technical solution, 6 moving hanging brackets 3 are installed at intervals along the length direction of the underground well hose 8. One end of the underground well hose 8 is connected to the oil delivery pipe 10 on the refueling vehicle body. For the first pipe receiving operation of the underground well hose 8, control the lifting cylinder 5 to descend until the upper proximity switch 12 is disengaged from the outer side of the cylinder body of the lifting cylinder 5. At this time, the first bracket 1 and the second bracket 2 are in the second state. Wind the underground well hose 8 around the outer sides of the first bracket 1 and the second bracket 2. Place the refueling connector 9 on the connector bracket 4, and keep the hooks 301 of the respective moving hanging brackets 3 facing the corresponding first bracket 1 / second bracket 2. Control the lifting cylinder 5 to ascend. During the ascending process of the first bracket 1 and the second bracket 2, they cooperate with the hooks 301 and drive the moving hanging brackets 3 and the underground well hose 8 connected thereto to move upward. When the lower proximity switch 13 forms an induction with the outer side of the cylinder body of the lifting cylinder 5, the first bracket 1 and the second bracket 2 are in the first state. As Figure 2As shown, the ground well hose 8 is suspended on the main frame at this time; during refueling operations, the operator performs an operation to release the hose for the ground well hose 8, controls the lowering of the lifting cylinder 5 until the upper proximity switch 12 is disengaged from the outer side of the cylinder body of the lifting cylinder 5. At this time, the first support 1 and the second support 2 are in the second state. During this process, the casters 302 of the 6 moving brackets 3 on the ground well hose 8 touch the ground, and the hooks 301 of the moving brackets 3 are automatically disengaged from the upper surfaces of the corresponding first support 1 and second support 2, as Figure 4 shown. The operator only needs to pull out the refueling connector 9 from the connector bracket 4 and drag it outwards to easily and quickly deploy the entire ground well hose 8 from the bottom of the vehicle; the entire operation of retracting and deploying the ground well hose 8 is convenient and fast, effectively reducing the labor intensity and improving the operation efficiency. At the same time, the split main frame structure composed of the first support 1 and the second support 2 does not increase the vehicle body length additionally, ensuring the downhill passing performance of the refueling vehicle.
