Description

Technical Field

[0001] This utility model relates to the technical field of refueling pipes, specifically to a refueling pipe surface anti-wear device. Background Technology

[0002] Fueling hoses are crucial equipment in the petroleum and chemical industries for transporting fluid media such as oil and natural gas. They are typically made of materials like steel pipes, wire ropes, and rubber, and are characterized by high pressure resistance, corrosion resistance, and wear resistance. The wear and tear of fueling hoses has always been a focus of industry attention, as it not only affects their service life but can also potentially lead to safety accidents.

[0003] Currently, commonly used anti-wear devices for refueling hoses are mostly integral sheaths or simple wrapping materials, typically using fixed rubber or metal sheaths directly covering the outer surface of the refueling hose. For refueling hoses that are frequently moved or dragged, these devices have the following drawbacks: the sheath and the refueling hose are in fixed contact, and when the refueling hose is dragged on the ground, the sheath rubs directly against the ground, leading to severe wear and frequent replacement after long-term use; simultaneously, due to the lack of cushioning and rolling structures, the dragging resistance is high, easily causing refueling hose deformation or loosening of joints; some sheaths use a split design, but installation is cumbersome and the sealing is poor, easily allowing sand and other impurities to enter, accelerating wear, increasing maintenance costs, and shortening the service life of the refueling hose. Therefore, a refueling hose surface anti-wear device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a wear-resistant device for the surface of a refueling hose, in order to solve the problems mentioned in the background art, where the sleeve and the refueling hose are in fixed contact, and the sleeve rubs directly against the ground when the refueling hose is dragged on the ground. After long-term use, the sleeve wears out severely and needs to be replaced frequently. At the same time, due to the lack of a buffer and rolling structure, the resistance is large when dragging, which can easily cause the refueling hose to deform or the joint to loosen. Some sleeves adopt a split design, but the installation is cumbersome and the sealing performance is poor, which can easily allow sand and other impurities to enter, aggravating wear, increasing maintenance costs, and shortening the service life of the refueling hose.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant device for a refueling pipe surface, comprising a first semi-circular clamp, a second semi-circular clamp, a wear-resistant component, a mounting component, and a refueling pipe, wherein the first semi-circular clamp and the second semi-circular clamp are symmetrically arranged and connected and fastened by the mounting component; The wear-resistant component includes a semi-circular outer shell and two arc-shaped retainers. A rubber connecting strip connects the two retainers. Ball bearings are movably embedded inside the retainers. Several through holes adapted to the ball bearings are evenly opened on the surface of the semi-circular outer shell. The mounting assembly includes two arc-shaped inserts. The first semi-circular clamp has two arc-shaped grooves on one side, and the arc-shaped inserts are slidably connected in the arc-shaped grooves. The second semi-circular clamp has two slots on the opposite side that are adapted to the arc-shaped inserts. A through groove is provided on one side of the arc-shaped groove, and a pull ring that passes through the through groove is fixedly connected to one side of the arc-shaped insert.

[0006] Preferably, a semi-circular rubber lip seal is provided between the semi-circular outer shell and the retainer, and the inner side of the semi-circular rubber lip seal is in contact with the outer side of the ball.

[0007] Preferably, the outer sides of the first and second semicircular clamps are provided with two sets of arc-shaped grooves that are adapted to the ball bearings, and the lower part of the ball bearings moves along the arc-shaped grooves.

[0008] Preferably, the second semi-circular clamp has two positioning holes on one side, and one end of the arc-shaped insert is inserted into the slot and then fixed by bolts. The slot has a tapered notch at the inlet.

[0009] Preferably, two arc-shaped baffles are fixedly connected to one side of the first semi-circular clamp, and the two arc-shaped baffles are respectively located near the two through slots.

[0010] Preferably, one end of the arc-shaped insert is fixedly connected to a first magnetic sheet, and the inner wall of the slot is fixedly connected to a second magnetic sheet, wherein the magnetic poles of the first magnetic sheet and the second magnetic sheet are opposite on opposite sides.

[0011] Preferably, the first and second semi-circular clamps are closed on the outside of the refueling pipe to form an annular clamping structure that fits against the outer wall of the refueling pipe.

[0012] Preferably, the inner walls of both the first and second semicircular clamps are provided with elastic pads.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: This invention utilizes a ball bearing structure in the anti-wear component, allowing the refueling hose to roll against the ground when dragged, significantly reducing frictional resistance and sheath wear, and substantially extending its service life. The arc-shaped retainer, combined with the buffer design of the rubber connecting strip, effectively absorbs the impact force during dragging, preventing refueling hose deformation and joint loosening. The use of a split clamp structure with a magnetic installation component enables quick assembly and disassembly while ensuring sealing, preventing sand and gravel from entering, and guaranteeing overall stability. This device has a simple and reliable structure, reducing maintenance costs while effectively protecting the refueling hose. Attached Figure Description

Example 1

[0019] In existing technologies, the sheath and the refueling hose are in fixed contact. When the refueling hose is dragged on the ground, the sheath rubs directly against the ground. After long-term use, the sheath wears out severely and needs to be replaced frequently. At the same time, due to the lack of a buffer and rolling structure, the resistance is large when dragging, which can easily cause the refueling hose to deform or the joint to loosen. Some sheaths adopt a split design, but the installation is cumbersome and the sealing is poor, which can easily allow sand and other impurities to enter, aggravating wear, increasing maintenance costs, and shortening the service life of the refueling hose.

[0020] Please see Figure 1-7 This utility model provides a technical solution: a wear-resistant device for the surface of a refueling pipe, comprising a first semi-circular clamp 1, a second semi-circular clamp 2, a wear-resistant component 3, a mounting component 4, and a refueling pipe 6. The first semi-circular clamp 1 and the second semi-circular clamp 2 are symmetrically arranged and connected and fastened by the mounting component 4. The inner walls of the first semi-circular clamp 1 and the second semi-circular clamp 2 are provided with elastic pads 5, which increases the friction between them and the refueling pipe 6. The first semi-circular clamp 1 and the second semi-circular clamp 2 are clamped together on the outside of the refueling pipe 6 to form an annular clamping structure that fits against the outer wall of the refueling pipe 6, thereby protecting the refueling pipe 6 from wear.

[0021] The wear-resistant component 3 includes a semi-circular housing 31 and two arc-shaped retainers 33. A rubber connecting strip 34 connects the two retainers 33. A ball bearing 35 is movably embedded inside the retainer 33. A semi-circular rubber lip seal 36 is provided between the semi-circular housing 31 and the retainers 33. The inner side of the semi-circular rubber lip seal 36 fits against the outer side of the ball bearing 35. The semi-circular rubber lip seal 36 is designed to prevent dust from entering the semi-circular housing 31 through the through hole 37 during the movement of the ball bearing 35, thus preventing it from affecting the normal movement of the ball bearing 35. The semi-circular rubber lip seal 36 is made of fluororubber, and its lip is designed with a 15° tilt angle to meet the ball bearing 35. An interference fit (compression 0.2-0.5mm) is formed. The outer sides of the first semi-circular clamp 1 and the second semi-circular clamp 2 are provided with two sets of arc-shaped grooves 32 that are adapted to the ball 35. The lower part of the ball 35 moves along the arc-shaped grooves 32. The arc-shaped grooves 32 guide the ball 35 and prevent the ball 35 from derailing during movement. The surface of the semi-circular outer shell 31 is evenly provided with several through holes 37 that are adapted to the ball 35. The lower part of the ball 35 and the arc-shaped grooves 32 adopt a clearance fit with a tolerance of H7 / g6 to ensure smooth rolling. The elastic modulus of the rubber connecting strip 34 is adapted to the impact force range of Shore hardness 50-60A.

[0022] Working principle or structural principle: When the refueling pipe 6 is pulled by external force or slides on the ground, the ball bearings 35 of the anti-wear component 3 roll along the outer side of the first semi-circular clamp 1 and the second semi-circular clamp 2 through the arc-shaped sliding groove 32, so that the ball bearings 35 slide in contact with the ground, replacing the direct friction of the refueling pipe 6 against the ground. When the ball bearings 35 move, the semi-circular rubber lip seal 36 prevents dust from entering the interior of the semi-circular outer shell 31 through the through hole 37. The arc-shaped retainer 33 is linked and buffered by the rubber connecting strip 34, so that the impact force of the ball bearings 35 is dispersed and absorbed by the elastic deformation of the arc-shaped retainer 33 and the rubber connecting strip 34. The elastic pad 5 increases the friction between the clamp and the refueling pipe 6. The mounting component 4 ensures the stability of the overall structure, and finally achieves anti-wear protection for the refueling pipe 6. Example 2

[0023] The mounting assembly 4 includes two arc-shaped inserts 41. Two arc-shaped grooves 42 are formed on one side of the first semi-circular clamp 1, and the arc-shaped inserts 41 are slidably connected within the arc-shaped grooves 42. Two slots 43, adapted to the arc-shaped inserts 41, are formed on the opposite side of the second semi-circular clamp 2. A first magnetic piece 46 is fixedly connected to one end of the arc-shaped insert 41, and a second magnetic piece 47 is fixedly connected to the inner wall of the slot 43. The magnetic poles of the first magnetic piece 46 and the second magnetic piece 47 are opposite on opposite sides. When the arc-shaped insert 41 is inserted into the slot 43, it is attracted by the opposite magnetic poles and quickly inserts into the deepest part of the slot 43. A through groove 44 is formed on one side of the arc-shaped groove 42. Two arc-shaped baffles 410 are fixedly connected to one side of the circular clamp 1. The two arc-shaped baffles 410 are located near the two through slots 44 respectively. The arc-shaped baffles 410 are to prevent dust or gravel on the ground from entering the through slots 44. A pull ring 45 that passes through the through slot 44 is fixedly connected to one side of the arc-shaped insert 41. Two positioning holes 49 are opened on one side of the second semi-circular clamp 2. After one end of the arc-shaped insert 41 is inserted into the slot 43, it is fixedly connected by bolts. The bolts pass through the positioning holes 49 to fix the arc-shaped insert 41 in the slot 43. A conical notch 48 is provided at the entrance of the slot 43 to facilitate the quick insertion of the arc-shaped insert 41 into the slot 43.

[0024] The working principle or structural principle is as follows: During installation, the first semi-circular clamp 1 and the second semi-circular clamp 2 are aligned so that the arc-shaped insert 41 is aligned with the slot 43. The pull ring 45 is pushed to insert the arc-shaped insert 41 into the slot 43. During the sliding insertion of the arc-shaped insert 41, the first magnetic piece 46 and the second magnetic piece 47 are accelerated to align due to magnetic attraction until they are fully inserted into the deepest part of the slot 43. Then, the arc-shaped insert 41 is fixed with a bolt through the positioning hole 49 to complete the clamp locking. The first magnetic piece 46 and the second magnetic piece 47 are made of neodymium iron boron material (N35 grade) with nickel plating for corrosion protection. The magnetic attraction force must be ≥10N to ensure alignment stability.

[0025] In summary, this utility model utilizes the rolling of the ball bearing 35 along the arc-shaped groove 32, so that when the refueling pipe 6 is pulled or slid, the ball bearing 35 replaces the contact with the ground, reducing direct friction. The impact force of the ball bearing 35 is buffered and abrasion-reduced by the arc-shaped retainer 33 through the rubber connecting strip 34, and the semi-circular rubber lip seal 36 prevents dust from entering. During installation, the arc-shaped insert 41 is quickly inserted into the slot 43 with the help of the magnetic attraction of the first magnetic piece 46 and the second magnetic piece 47, and the bolt is locked through the positioning hole 49. The elastic pad 5 enhances the friction between the clamp and the refueling pipe 6, ensuring overall stability and anti-wear effect.
