Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a wind and sand protection support. Background Art

[0002] Bridge bearings are key components of bridge structures, connecting the beams and piers. They stably transfer the load and deformation of the upper beam to the pier structure, ensuring the upper structure can deform freely under load and temperature changes. The bridge bearings primarily function in the friction pair composed of stainless steel plates and wear-resistant plates, which are also the core components of the bridge bearings. Once dust and impurities accumulate in the friction pair, causing the friction pair to lose its function, the bridge bearings also lose their basic function, which directly affects the safety and durability of the bridge structure and poses a safety hazard to traffic on the line.

[0003] To protect bridge bearings from corrosion during long-term use, exposed metal surfaces must generally be coated with an anti-corrosion coating. Paint is the most commonly used coating method, and a complete paint coating provides excellent corrosion protection. However, once the coating is damaged, even small holes can cause cracking and flake-off, leading to corrosion failure and shortening the bearing lifespan.

[0004] In addition, when installing bridge bearings, a layer of rubber or polyurethane panels will be installed around the bearings to prevent dust. However, rubber and polyurethane materials are relatively soft in texture and are affected by their own properties. They are easily torn and damaged when exposed to outdoor environments for a long time, and they have no protective effect.

[0005] The applicant has discovered that the prior art suffers from at least the following technical issues: When bridge bearings are used in areas with harsh climates and severe sandstorms, the anti-corrosion coating on the bearing surface is easily eroded by the wind and sand, shortening the bearing's lifespan. Over time, small amounts of dust accumulation can enter the bearing's sliding pair, severely impacting its proper sliding and rotational properties. This leads to a sharp increase in the friction coefficient and wear on the sliding plate, severely adversely affecting bearing performance. Furthermore, dust accumulation can hinder subsequent bearing care, maintenance, and replacement. Utility Model Content

[0006] The purpose of this utility model is to provide a wind-sandproof bearing to address the existing technical problems of bridge bearings in service in areas with high wind and sand activity. Wind-sand erosion not only damages the bearing's anti-corrosion coating, shortening the bearing's service life, but also affects the friction pair if wind-sand enters the bearing, affecting the proper function of the bridge bearing and the safety of the overall structure. Furthermore, accumulation of wind-sand affects the bearing's maintenance. The various technical effects produced by the preferred technical solution among the various technical solutions provided by this utility model are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A wind and sand proof bearing comprises an upper bearing plate, a spherical crown lining plate and a lower bearing plate connected in sequence from top to bottom, and a surrounding plate connected to the side of the upper bearing plate, and also comprises an upper sand-proof plate and a lower sand-discharging plate. The upper sand-proof plate is connected to the outer side of the surrounding plate, the upper sand-proof plate is vertically arranged and a first hanging ear connection portion is provided at the bottom thereof, the lower sand-discharging plate is inclined and a second hanging ear connection portion is provided at the top thereof, the second hanging ear connection portion can be hung on the first hanging ear connection portion so that the upper sand-proof plate and the lower sand-discharging plate can be detachably connected.

[0009] Preferably, it also includes a dust-proof brush, the fixed end of which is connected to the top surface of the lower support plate, the brush end of which is in contact with the bottom surface of the upper support plate, and the dust-proof brush is located on the outside of the spherical crown lining.

[0010] Preferably, a sealing rubber piece is further included, and the sealing rubber piece is connected to the lower end of the lower sand discharge plate to fill the gap between the lower sand discharge plate and the support pad stone of the pier.

[0011] Preferably, the upper support plate has four side surfaces, each of the side surfaces is connected to a panel, each of the panel surfaces is connected to an upper sand-proof plate, and each of the upper sand-proof plates is connected to a lower sand-discharge plate.

[0012] Preferably, the upper sand-proof plate is bolted to the upper support plate after a plurality of first connecting bolts pass through the corresponding enclosure plate.

[0013] Preferably, the side ends of the upper sand-proof plates are provided with cut corners so that the side ends of two adjacent upper sand-proof plates can be closely butted against each other.

[0014] Preferably, the two adjacent lower sand discharge plates are detachably connected together at the connection point.

[0015] Preferably, a connecting plate is provided at the side end of the lower sand discharge plate, and the two connecting plates at the connection point of two adjacent lower sand discharge plates are bolted together by a second connecting bolt.

[0016] The beneficial effects of the utility model are as follows: the upper sand-proof plate and the lower sand-discharging plate are designed with a hook-type structure, which is convenient for disassembly and assembly, and can also meet the requirements of the normal rotation angle of the support. The lower sand-discharging plate adopts an inclined slope design. When the sand and dust accumulate to a certain extent, it can automatically fall off from the lower sand-discharging plate, thereby reducing the number of manual sand removal maintenance times and achieving excellent sand-discharging performance.

[0017] The upper sand-proof plate and the lower sand-discharging plate can cooperate with each other and serve as the first-level protection of the wind-proof sand bearing. They can not only block the wind and sand from damaging the anti-corrosion coating of the bearing, but also prevent the wind and sand from entering the interior of the bearing, ensuring the stable realization of the bearing function. At the same time, they can prevent excessive accumulation of sand and dust, facilitating the later maintenance of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0033] Reference Figures 1 to 3 The utility model provides a wind and sand support, comprising an upper support plate 1, a spherical crown lining plate 2 and a lower support plate 3 connected in sequence from top to bottom, and a panel 4 connected to the side of the upper support plate 1. The upper support plate 1 corresponding to this embodiment has four side surfaces, so that each side surface is connected to a panel 4;

[0034] The wind and sand support further includes an upper sand-proof plate 5 and a lower sand-discharging plate 6. The upper sand-proof plate 5 is connected to the outer side of the enclosure plate 4. Each enclosure plate 4 is connected to an upper sand-proof plate 5, so that the four upper sand-proof plates 5 can enclose the upper support plate 1. The upper sand-proof plate 5 is vertically arranged and has a first hanging ear connection portion 51 at its bottom.

[0035] The lower sand-discharging plate 6 is arranged at an angle and a second hanging ear connection portion 61 is provided on the top thereof. The second hanging ear connection portion 61 can be hung on the first hanging ear connection portion 51, so that the upper sand-proof plate 5 and the lower sand-discharging plate 6 can form a detachable connection. Each upper sand-proof plate 5 is connected to a lower sand-discharging plate 6.

[0036] The upper sand-proof plate 5 and the lower sand-discharging plate 6 are designed with a hook-type structure, which is convenient for disassembly and assembly, and can also meet the requirements of the normal rotation angle of the support. The lower sand-discharging plate 6 adopts an inclined slope design. When the sand and dust accumulate to a certain extent, it can automatically fall off from the lower sand-discharging plate 6, thereby reducing the number of manual sand removal maintenance times and achieving excellent sand-discharging performance.

[0037] The upper sand-proof plate 5 and the lower sand-discharging plate 6 can cooperate with each other and serve as the first-level protection of the wind-proof sand bearing. They can not only block the wind and sand from damaging the anti-corrosion coating of the bearing, but also prevent the wind and sand from entering the interior of the bearing, ensuring the stable realization of the bearing function. At the same time, they can prevent excessive accumulation of sand and dust, which is convenient for the later maintenance of the bearing.

[0038] As an optional embodiment, it further includes a dust-proof brush 7, the fixed end of the dust-proof brush 7 is connected to the top surface of the lower support plate 3, the brush end of the dust-proof brush 7 is in contact with the bottom surface of the upper support plate 1, preferably in contact with the stainless steel plate on the bottom surface of the upper support plate 1, and the dust-proof brush 7 is located on the outer side of the spherical crown lining plate 2;

[0039] The dust-proof brush 7 not only plays a role in sealing and dust prevention, but also can cause relative displacement with the stainless steel plate on the bottom surface of the upper support plate 1 when the support slides and rotates, so that the support has a self-cleaning function. Therefore, on the basis of the upper sand-proof plate 5 and the lower sand-discharging plate 6, the dust-proof brush 7 can form a second level of protection for the anti-sand support, ensuring the cleanliness of the plane and spherical friction surfaces and the friction coefficient of the friction pair;

[0040] In this embodiment, the overall shape of the dust-proof brush 7 is not specifically limited, but it is necessary to form an encircling effect in the circumferential direction of the spherical cap lining 2 to ensure complete coverage in the circumferential direction. Therefore, the dust-proof brush 7 can be further preferably an annular structure.

[0041] As an optional embodiment, a sealing rubber member 8 is further included. The sealing rubber member 8 is connected to the lower end of the lower sand discharge plate 6. The sealing rubber member 8 can fill the gap between the lower sand discharge plate 6 and the support pad stone of the bridge pier, thereby playing a sealing role between the lower sand discharge plate 6 and the support pad stone of the bridge pier, and preventing sand and dust from entering the interior of the support through the bottom gap of the lower sand discharge plate 6;

[0042] On the basis of the upper sand-proof plate 5, the lower sand-discharging plate 6 and the dust-proof brush 7, the sealing rubber part 8 can form the third level of protection as the wind and sand proof bearing. Through the above three levels of protection, multiple protections can be added to the bearing, which can not only ensure that the surface of the bearing is corrosion-resistant and not eroded, but also prevent sand and dust from entering the interior of the bearing. It can not only ensure the stable realization of the bearing function, but also prevent excessive accumulation of sand and dust, which is convenient for the later maintenance of the bearing.

[0043] As an optional embodiment, the upper sand-proof plate 5 is bolted to the upper support plate 1 by passing through the corresponding coaming plate 4 through a plurality of first connecting bolts 52. At the same time, the side ends of the upper sand-proof plate 5 are provided with bevels to ensure that the side ends of two adjacent upper sand-proof plates 5 are tightly butted together.

[0044] With such arrangement, the four upper sand-proof plates 5 can form a whole after being bolted to the upper support plate 1 , and the overall rigidity is higher and the ability to prevent wind and sand is stronger.

[0045] As an optional embodiment, two adjacent lower sand discharge plates 6 can be detachably connected together at the connection point. Such an arrangement enables all the lower sand discharge plates 6 to form a whole when connected, thereby improving the overall rigidity, increasing safety, and making it easier to disassemble and assemble.

[0046] As an optional embodiment, a connecting plate 62 is provided at the side end of the lower sand discharge plate 6, and the two connecting plates 62 at the connection of two adjacent lower sand discharge plates 6 are bolted together by a second connecting bolt 63;

[0047] In actual operation, since the four lower sand discharge plates 6 all have inclined surfaces, the connecting plate 62 of one of the two adjacent lower sand discharge plates 6 can be parallel to the plane of the lower sand discharge plate 6, and the other connecting plate 62 needs to form a bending angle with the lower sand discharge plate 6, so that the two adjacent connecting plates 62 can fit each other at the connection, making it easy to connect the second connecting bolt 63.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
