Description

Technical Field

[0001] The utility model relates to the technical field of refueling vehicles, in particular to a movable hanging 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 underground well hoses. During operation, the operator holds the refueling connector at the front end of the underground well hose and drags it to the underground well nozzle for docking. During the whole process, the underground well hose will be damaged by friction and dragging on the ground, posing a safety hazard of oil leakage. Moreover, after the underground well hose is filled with oil, it is difficult to move, which is not convenient for the hose collection operation after the operation is completed. Content of the Utility Model

[0003] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a movable hanging rack for the underground well hose of a pipeline refueling vehicle, which can realize the convenient movement of the underground well hose and provide effective protection for the surface of the underground well hose during the movement process.

[0004] The technical solution of the utility model is as follows: A movable hanging rack for the underground well hose of a pipeline refueling vehicle, including a pipe clamp, a hook, a caster and a fastening bolt. The pipe clamp is formed by docking an upper clamping plate and a lower clamping plate. The hook is installed on the top of the upper clamping plate, and the caster is installed on the bottom of the lower clamping plate. Semi-circular holes are provided on the docking surface of the upper clamping plate and the lower clamping plate, and the semi-circular holes can be docked to form a through hole for the underground well hose to pass through. The fastening bolt sequentially passes through the upper clamping plate and the lower clamping plate and is connected to a fastening nut. The underground well hose is clamped and protected by the upper and lower clamping plates. During the docking and hose collection operations, the caster at the bottom of the lower clamping plate can reduce the resistance during the movement process. At the same time, the hook on the top of the upper clamping plate provides a detachable connection between the underground well hose and the refueling vehicle chassis, which is flexible and convenient to use and effectively protects the underground well hose.

[0005] The upper clamping plate and the lower clamping plate are made of rubber material. The rubber material clamping plates generate less radial and axial forces on the underground well hose made of the same rubber material, preventing the surface of the underground well hose from being damaged due to pressing.

[0006] The hook is connected to the upper clamping plate through an upper mounting plate, and the caster is connected to the lower clamping plate through a lower mounting plate.

[0007] The upper mounting plate is bent into a U-shaped structure with wings extending along the length direction at both ends. The wings are fixedly connected to the upper clamping plate through fastening bolts. The lower end of the hook has a threaded portion, and the threaded portion is disposed through the horizontal section of the U-shaped structure of the upper mounting plate. Fixing nuts and adjusting nuts are respectively threadedly connected to the threaded portions on both sides of the upper mounting plate. The height of the hook extending out of the upper mounting plate can be adjusted by the fixing bolt and the adjusting bolt, and it can be adapted to the chassis at different heights on different models of refueling vehicles.

[0008] An internal thread groove for mating connection with the threaded portion is provided at the top of the upper clamping plate. The setting of the internal thread groove enables the threaded portion of the hook to form two-point fixation between the upper clamping plate and the upper mounting plate, ensuring the stability of the mobile hanging rack.

[0009] The length of the lower mounting plate is greater than that of the lower clamping plate. The lower mounting plate is fixedly connected to the lower clamping plate through fastening bolts. There are two casters, symmetrically distributed below the lower mounting plate on both sides of the lower clamping plate along the length direction. The casters are connected to caster nuts through the screw rod portions penetrating the lower mounting plate.

[0010] The end of the wing plate extends outward and is bent twice to form an outer side plate and an inner clamping plate in sequence. The inner clamping plate is connected to the lower mounting plate through the screw rod portion of the caster. The wing plate of the upper mounting plate is bent and then connected to the lower mounting plate, improving the lateral stability and strength of the entire mobile hanging rack.

[0011] Both sides of the lower mounting plate in the width direction are bent upward to form side plates, and the lower clamping plate is located between the two side plates. The bending of the side plates on both sides of the lower mounting plate can further improve the support strength of the lower mounting plate.

[0012] A lifting rod is provided on the hook, and the lifting rod is fixed on one side of the hook opposite to the hook portion.

[0013] The beneficial effects of the present utility model are as follows: In this solution, the upper and lower clamping plates are used to clamp and protect the underground well rubber hose. During the docking and pipe-receiving operations, the casters at the bottom of the lower clamping plate can reduce the resistance during the moving process. At the same time, the hook at the top of the upper clamping plate provides a detachable connection between the underground well rubber hose and the refueling vehicle chassis, which is flexible and convenient to use and effectively protects the underground well rubber hose.

Detailed implementation manners

[0019] To enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 3 shown, the present invention provides a mobile hanger for an underground well hose of a pipeline refueling vehicle, including a pipe clamp 1, a hook 6, a caster 7 and a fastening bolt 4. The pipe clamp 1 is formed by docking an upper clamping plate 101 and a lower clamping plate 102. The hook 6 is connected to the top of the upper clamping plate 101 through an upper mounting plate 2 for hanging and connecting with the chassis 11 of the refueling vehicle. The caster 7 is connected to the bottom of the lower clamping plate 102 through a lower mounting plate 3. Semi-circular holes 103 capable of docking to form a through hole for the underground well hose 12 to pass through are provided on the docking surface of the upper clamping plate 101 and the lower clamping plate 102. The fastening bolt 4 sequentially passes through the upper clamping plate 101 and the lower clamping plate 102 and then is connected to a fastening nut 5. Specifically, there are two fastening bolts 4, symmetrically distributed on both sides of the semi-circular hole 103; As Figure 1 shown, a plurality of such mobile hangers are arranged along the length direction of the underground well hose 12. After the upper clamping plates 101 and the lower clamping plates 102 of each mobile hanger are docked, they are fixed on the underground well hose 12 through the fastening bolts 4, so as to realize the clamping and protection of the underground well hose 12. Further preferably, the upper clamping plate 101 and the lower clamping plate 102 are made of rubber. When the clamping plates made of rubber material clamp the underground well hose 12 made of the same rubber material, compared with the metal material, the radial and axial acting forces generated by them are smaller, which can effectively prevent the surface of the underground well hose 12 from being damaged due to pressing.

[0021] As Figure 2 shown, during the docking and pipe receiving operations, due to the presence of the casters 7 at the bottom of the lower clamping plate 102, the resistance of the operator to move the underground well hose 12 can be reduced, and the setting of the hook 6 at the top of the upper clamping plate 101 realizes the detachable connection between the underground well hose 12 and the chassis 11 of the refueling vehicle, making the operation flexible and convenient.

[0022] As Figure 2 and Figure 3As shown, a lifting rod 10 is provided on the hook 6. The lifting rod 10 is fixed on one side of the back of the hook 6 facing away from the hook 6. With the assistance of the lifting rod 10, an operator can perform the suspension or detachment operation of the hook 6 and the chassis 11.

[0023] As Figure 3 and Figure 4 shown, the upper mounting plate 2 is bent to form a U-shaped structure 201 with wing plates 202 extending along the length direction at both ends. The wing plates 202 are fixedly connected to the upper clamping plate 101 through fastening bolts 4. The lower end of the hook 6 has a threaded portion, and the threaded portion penetrates through the horizontal section of the U-shaped structure 201 of the upper mounting plate 2. Fixing nuts 8 and adjusting nuts 9 are respectively threadedly connected to the threaded portions on both sides of the upper mounting plate 2. By adjusting the height of the hook 6 protruding from the upper mounting plate 2 through the fixing bolts and adjusting bolts, it can be adapted to the chassis 11 at different heights on different types of refueling vehicles, improving the practicability of this mobile hanging rack.

[0024] As Figure 3 shown, further, an internal thread groove 104 for mating connection with the threaded portion is provided at the top of the upper clamping plate 101. After the threaded portion of the hook 6 is connected to the internal thread groove 104, at this time, two-point fixation is formed between the lower end of the hook 6 and the upper clamping plate 101 and the upper mounting plate 2, effectively improving the connection stability between the hook 6 and the upper mounting plate 2.

[0025] The length of the lower mounting plate 3 is greater than the length of the lower clamping plate 102. The lower mounting plate 3 is fixedly connected to the lower clamping plate 102 through fastening bolts 4. There are two casters 7, which are symmetrically distributed below the lower mounting plate 3 on both sides of the lower clamping plate 102 along the length direction. The casters 7 are connected to the caster nuts through the screw portions penetrating the lower mounting plate 3. Each caster 7 can rotate and roll 360 degrees horizontally, realizing the towing movement and turning of the wellhead hose 12 during deployment and retraction.

[0026] To improve the lateral stability and strength of the entire mobile hanging rack, as Figure 3 and Figure 4 shown, the end of the wing plate 202 extends outward and is bent twice in sequence to form an outer side plate 203 and an inner clamping plate 204. The inner clamping plate 204 is connected to the lower mounting plate 3 through the screw portion of the caster 7.

[0027] To improve the vertical support strength of the entire mobile hanging rack, both sides of the lower mounting plate 3 along the width direction are bent upward to form side plates, and the lower clamping plate 102 is located between the two side plates.

[0028] When implementing this technical solution, this mobile hanging rack is installed at equal intervals along the length direction of the ground well rubber hose 12. The pipe clamp 1 made of rubber provides protection for the outer side of the ground well rubber hose 12. At the same time, the bending structures of the upper mounting plate 2 and the lower mounting plate 3 wrap around the outer side of the pipe clamp 1, making this mobile hanging rack have the characteristics of high strength and high stability. It is quickly detachably connected to the chassis 11 through the hook 6, and with the help of the movable and steering performance of the casters 7, the operator can stably and quickly deploy and recover the ground well rubber hose 12, greatly reducing the labor intensity of the operator.
