Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pier technology, and in particular relates to a high-impact and abrasion-resistant composite concrete pier. Background Technology
[0002] Piers are the load-bearing structures in civil engineering that support the superstructure. Pier cross-sections are mostly circular, but elliptical, square, curved, parabolic, and other irregular shapes also exist. They are an important component in highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, and pedestrian bridges.
[0003] Because some of the piers of the viaduct are located in the middle of the intersection, and the turning maneuvers of vehicles at the intersection are relatively complicated, they are prone to accidentally hitting the piers. The load-bearing parts of the conventional piers are difficult to repair, resulting in the problem that conventional concrete piers have relatively low impact and abrasion resistance.
[0004] To address these issues, we propose a high-impact-abrasion-resistant concrete composite pier. Utility Model Content
[0005] The purpose of this invention is to solve the problem of low impact and abrasion resistance of conventional concrete piers, and to propose a composite concrete pier with high impact and abrasion resistance.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A highly impact- and abrasion-resistant concrete composite pier includes a concrete pier body. A metal sleeve is fixedly connected to the lower part of the concrete pier body. A rotating sleeve is rotatably mounted on the outside of the metal sleeve. A rubber plate is snapped onto the outside of the rotating sleeve. A dust-blocking ring is movably sealed on the upper part of the rotating sleeve, and the dust-blocking ring is fixedly mounted on the upper part of the metal sleeve. Using a syringe, lubricating oil is injected between the rotating sleeve and the dust-blocking ring, allowing the lubricating oil to penetrate between the metal sleeve and the rotating sleeve, reducing the rotational resistance between them. When a vehicle accidentally scrapes the device, the rubber plate preferentially contacts the offending vehicle. The rubber plate acts on the rotating sleeve, causing it to rotate along the metal sleeve, changing the direction of travel of the offending vehicle and preventing all the kinetic energy of the offending vehicle from being transferred to the concrete pier body, thus improving impact resistance. The rubber plate replaces abrasion, improving wear resistance.
[0008] Preferably, the concrete pier body includes a concrete column and a reinforcing ring, the reinforcing ring being fixedly connected to the lower part of the concrete column; the metal sleeve is fixedly connected between the concrete pier body and the reinforcing ring. The reinforcing ring increases the stability of the lower structure of the concrete column, expands the connection range between the concrete pier body and the embedded parts, and raises the position of the metal sleeve, reducing the erosion rate of the metal sleeve by road surface water.
[0009] Preferably, the metal sleeve includes a fixing sleeve and a washer ring. The lower end of the fixing sleeve is fixedly connected to the upper end of the washer ring, and the fixing sleeve and the washer ring are an integral structure. The washer ring is placed on the reinforcing ring, and the fixing sleeve is fixedly fitted onto the concrete column. The washer ring, placed on the reinforcing ring, prevents friction between the rotating sleeve and the reinforcing ring. The fixing sleeve, placed between the rotating sleeve and the concrete column, also prevents friction between them, thus facilitating the protection of the concrete pier column body.
[0010] Preferably, the fixed sleeve has a guide groove on its exterior. When particles enter between the metal sleeve and the rotating sleeve, the guide groove accommodates the particles, while the rotating sleeve guides the particles to flow downwards, facilitating wastewater discharge.
[0011] Preferably, the rotating sleeve includes a rotating sleeve body, the outer side of which has a slot; the rubber plate is secured in the slot, the rotating sleeve body is rotatably sleeved on the outside of the fixed sleeve, and the lower end of the rotating sleeve body is in movable contact with the washer ring. When the rubber plate is severely worn, it can be pulled out of the slot and a new rubber plate can be inserted. When the rubber plate is subjected to a force not directly opposite the center of the rotating sleeve body, the rotating sleeve body is rotated by the rubber plate to change the direction of the force source, which facilitates the replacement of the rubber plate and also facilitates changing the direction of the impacting vehicle.
[0012] Preferably, the upper part of the slot has a guide opening. The guide opening is used to guide the rubber plate into the slot, facilitating the installation of the rubber plate.
[0013] Preferably, the dust-blocking ring includes a fixing ring and a retaining ring. The lower end of the fixing ring is fixedly connected to the inner end of the retaining ring. The fixing ring is fixedly connected to the upper part of the fixing sleeve, and the retaining ring seals and presses against the upper end of the rotating sleeve body. The syringe needle is passed through the gap between the retaining ring and the rotating sleeve body to inject lubricating oil into the groove on the upper part of the rotating sleeve body. Then, the rotating sleeve is rotated to evenly distribute the oil between the metal sleeve and the rotating sleeve. The retaining ring blocks the upper opening of the rotating sleeve, preventing dust from entering.
[0014] Preferably, the rubber sheet includes an insert plate and a baffle plate, the insert plate and the baffle plate being fixedly connected as a single unit; the insert plate is inserted into a slot, and the baffle plate is positioned outside the slot. The baffle plate, positioned outside the rotating sleeve, prevents impact vehicles from directly impacting the rotating sleeve, thus protecting it.
[0015] In summary, the technical effects and advantages of this utility model are as follows:
[0016] 1. Using a syringe, lubricating oil is injected between the rotating sleeve and the dust-blocking ring, allowing the lubricating oil to penetrate between the metal sleeve and the rotating sleeve, reducing the rotational resistance between them. When a vehicle accidentally scrapes the device, the rubber plate makes priority contact with the offending vehicle. The rubber plate acts on the rotating sleeve, causing it to rotate along the metal sleeve, changing the direction of the offending vehicle's travel. This prevents the kinetic energy of the offending vehicle from being entirely applied to the concrete pier body, improving impact resistance. The rubber plate replaces the wear material, improving wear resistance and facilitating the protection of piers in easily impacted areas.
[0017] 2. The reinforcement ring increases the stability of the lower structure of the concrete column. At the same time, the reinforcement ring increases the connection range between the concrete pier and the embedded parts. The reinforcement ring also raises the position of the metal sleeve, reducing the erosion rate of the metal sleeve by road surface water.
[0018] 3. Use a washer ring to block the reinforcing ring to prevent friction between the rotating sleeve and the reinforcing ring. Use a fixed sleeve to block between the rotating sleeve and the concrete column to prevent friction between the rotating sleeve and the concrete column, thus protecting the concrete pier column body.
[0019] 4. When particles enter between the metal sleeve and the rotating sleeve, the guide groove accommodates the particles, and the rotating guide oil guides the particles to flow downwards, facilitating auxiliary sewage discharge.
[0020] 5. When the rubber plate is severely worn, pull the rubber plate upward from the slot and insert a new rubber plate. When the rubber plate is subjected to a force that is not directly opposite the center of the rotating sleeve body, the rubber plate drives the rotating sleeve body to rotate, changing the direction of the force source. This makes it easier to replace the rubber plate and also makes it easier to change the direction of the impacting vehicle.
[0021] 6. Use the guide port to guide the rubber plate into the slot for easy installation.
[0022] 7. Pass the syringe needle through the gap between the retaining ring and the rotating sleeve body, inject lubricating oil into the groove on the upper part of the rotating sleeve body, and then rotate the rotating sleeve to evenly distribute the oil between the metal sleeve and the rotating sleeve. Use the retaining ring to block the upper opening of the rotating sleeve to prevent dust from entering. Attached Figure Description
