Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and in particular to a dustproof enclosure structure for bridge bearings. Background Technology

[0002] Bridge bearings are an important component of bridge structures, and their quality directly affects the service life and structural safety of the bridge. After installation, if bridge bearings are not properly protected, dust or water can corrode and contaminate them, directly impacting their normal use and service life.

[0003] Existing technologies, such as utility model patent CN212714558U, disclose a dustproof enclosure structure for bridge bearings used in highway construction. It includes a bridge bearing, a dustproof enclosure assembly for vibration damping and dust prevention, and a fixing assembly for fixing one end of the dustproof enclosure assembly to the bottom surface of the beam and the other end to the pier. The dustproof enclosure assembly includes a front panel, a rear panel, a left panel, and a right panel. Each of the front, rear, left, and right panels includes a shell, a first annular sound-absorbing and vibration-damping layer disposed within the shell, and a second annular sound-absorbing and vibration-damping layer disposed within the first annular sound-absorbing and vibration-damping layer. A rubber layer is disposed between the shell and the first annular sound-absorbing and vibration-damping layer. This utility model has a simple structure, reasonable design, convenient installation, saves time and labor, has good vibration damping effect, and high construction efficiency, making it worthy of widespread promotion and use.

[0004] In existing technologies, dustproof enclosures for bridge bearings are often fixed-size structures. When faced with bridge bearings of different sizes, the size of the enclosures cannot be flexibly adjusted to achieve a tight fit, leading to numerous inconveniences during installation and hindering their effective dustproof function. Furthermore, existing dustproof enclosure structures are insufficiently designed for vibration damping. When the bridge is subjected to vibration or impact, they cannot provide adequate shock absorption protection for the bridge bearings and beams. Long-term use can easily cause damage to bridge structural components, affecting the bridge's service life and safety. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of poor adaptability to bridge bearings of different sizes and poor shock absorption effect in the existing technology, and to propose a dustproof enclosure structure for bridge bearings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof enclosure structure for a bridge bearing, comprising a pier, a bridge bearing body fixedly connected to the top of the pier, a beam fixedly connected to the top of the bridge bearing body, a lower protective plate provided on the outer side of the bridge bearing body, the bottom of the lower protective plate fixedly connected to the top of the pier, an upper protective plate fixedly connected to the top of the lower protective plate, the top of the upper protective plate fixedly connected to the bottom of the beam, a shock-absorbing component fixedly connected to the bottom of the beam, the lower protective plate comprising a first semi-circular plate and a second semi-circular plate, both the first and second semi-circular plates fixedly connected to the top of the pier, the first and second semi-circular plates fixedly connected by bolts, an adjusting buffer device fixedly connected to the inner wall of both the first and second semi-circular plates, and a fixing ring fixedly connected to the end of the adjusting buffer device away from the first semi-circular plate.

[0007] Furthermore, the adjusting buffer device includes a first connecting plate, which is fixedly connected to the inner wall of the first semi-arc plate.

[0009] Furthermore, the end of the electric actuator away from the first connecting plate is fixedly connected to a second connecting plate, and the second connecting plate is fixedly connected to the second fixing block.

[0010] Furthermore, the upper protective plate includes a first sleeve ring and a second sleeve ring.

The position of the fixed ring can be flexibly adjusted according to the actual size of the bridge bearing, so that the enclosure can closely fit bridge bearings of different sizes, greatly improving the adaptability to bridge bearings of different sizes.

[0015] 2. In this utility model, by setting a damping component consisting of a damping rod and a shock-absorbing spring at the bottom of the beam, and setting a buffer component with a buffer spring on the inner wall of the lower protective plate, the beam provides stable shock absorption protection for the bridge when it vibrates due to factors such as vehicle traffic and wind.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a dustproof enclosure structure for a bridge bearing, including a pier 1, a bridge bearing body 2 fixedly connected to the top of the pier 1, a beam 3 fixedly connected to the top of the bridge bearing body 2, a lower protective plate 4 provided on the outer side of the bridge bearing body 2, the bottom of the lower protective plate 4 fixedly connected to the top of the pier 1, an upper protective plate 5 fixedly connected to the top of the lower protective plate 4, the top of the upper protective plate 5 fixedly connected to the bottom of the beam 3, and a shock-absorbing component 6 fixedly connected to the bottom of the beam 3.

[0024] The following section will explain the specific setup and function of the lower protective plate 4 and the shock absorption component 6.

[0025] In this embodiment: the lower protective plate 4 includes a first semi-arc plate 41 and a second semi-arc plate 42. The first semi-arc plate 41 and the second semi-arc plate 42 are both fixedly connected to the top of the pier 1. The first semi-arc plate 41 and the second semi-arc plate 42 are fixedly connected by bolts. The inner walls of the first semi-arc plate 41 and the second semi-arc plate 42 are both fixedly connected to an adjusting buffer device 43. The end of the adjusting buffer device 43 away from the first semi-arc plate 41 is fixedly connected to a fixing ring 44.

[0026] The aforementioned components achieve the following effects: the first semi-circular plate 41 and the second semi-circular plate 42 are connected by bolts, facilitating installation and disassembly, and allowing for flexible assembly according to on-site construction conditions. The adjusting buffer device 43, in conjunction with the fixing ring 44, provides an adjustable fastening and buffering protection base for bridge bearings of different sizes.

[0027] Specifically, the adjusting buffer device 43 includes a first connecting plate 431, which is fixedly connected to the inner wall of the first semi-arc plate 41. The upper and lower ends of the surface of the first connecting plate 431 away from the first semi-arc plate 41 are fixedly connected to electric push rods 432, and a plurality of buffer components 433 are arranged between the electric push rods 432.

[0028] The effect achieved by the above components is as follows: the first connecting plate 431 serves to stabilize the electric push rod 432, and the electric push rod 432 can accurately adjust the extension or retraction length. According to the outer diameter of the bridge bearing, it drives the buffer assembly 433 and the fixing ring 44 to move, thereby achieving a close fit to bridge bearings of different sizes and greatly improving the versatility of the enclosure.

[0029] Specifically, the buffer assembly 433 includes a first fixing block 4331, which is fixedly connected to the inner wall of the first semi-arc plate 41. A buffer spring 4332 is fixedly connected to the surface of the first fixing block 4331, and a second fixing block 4333 is fixedly connected to the end of the buffer spring 4332 away from the first fixing block 4331.

[0030] The effect achieved by the above components is that when the bridge is subjected to vibration, the buffer spring 4332 can be effectively compressed and rebounded, converting the impact force generated by the vibration into the elastic potential energy of the spring. Through the transmission and buffering of the first fixed block 4331 and the second fixed block 4333, the direct effect of vibration on the bridge support is reduced, and the bridge support is protected from vibration damage.

[0031] Specifically, the end of the electric actuator 432 away from the first connecting plate 431 is fixedly connected to the second connecting plate 434, and the second connecting plate 434 is fixedly connected to the second fixing block 4333.

[0032] The effect achieved by the above components is that the second connecting plate 434 ensures that the power of the electric push rod 432 can be stably transmitted to the buffer assembly 433, so that when the electric push rod 432 is adjusted, it can drive the buffer assembly 433 and the fixing ring 44 to move synchronously, thus ensuring the stability and coordination of the entire adjusting buffer device 43 during operation.

[0033] Specifically, the upper protective plate 5 includes a first connecting ring 51 and a second connecting ring 52. The first connecting ring 51 is fixedly connected to the top of the first semi-arc plate 41, and the second connecting ring 52 is fixedly connected to the top of the second semi-arc plate 42. The first connecting ring 51 and the second connecting ring 52 are fixedly connected by bolts.

[0034] The effect achieved by the above components is as follows: the structural design of the upper protective plate 5 makes it easy to install, and it fits tightly with the lower protective plate 4 to form a complete dust cover structure, which can effectively block dust, debris and other objects from entering the bridge bearing, reduce wear and failure caused by dust accumulation, and extend the service life of the bridge bearing.

[0035] In this implementation scheme: the damping component 6 includes a damping rod 61, which is fixedly connected to the bottom of the beam 3. A damping spring 62 is fixedly connected to the outer surface of the damping rod 61. Several damping components 6 are arranged at the bottom of the beam 3.

[0036] The aforementioned components achieve the following effect: multiple damping components 6 work together. When the beam 3 vibrates due to factors such as vehicle movement and wind, the damping spring 62 first acts as a preliminary buffer, converting some of the vibration energy into elastic potential energy. The damping rod 61, through its own damping characteristics, consumes the remaining vibration energy, suppresses excessive spring rebound, and rapidly attenuates the vibration of the beam 3, providing stable vibration protection for the bridge.

[0037] Specifically, a support block is fixedly connected to the outer surface of the lower protective plate 4, and the bottom end of the support block is fixedly connected to the top of the pier 1 by bolts.

[0038] The effect achieved by the above components is that the support block enhances the structural stability of the lower protective plate 4, so that it can maintain a stable installation state even when subjected to external impacts or vibrations during long-term use.

[0039] Working principle: When installing the dustproof enclosure of this bridge bearing, firstly, according to the dimensions of the bridge bearing body 2, start the electric actuator 432. The electric actuator 432 drives the buffer assembly 433 and the fixing ring 44 to move through the second connecting plate 434, adjusting the fixing ring 44 to a suitable position so that it can fit tightly against the outer side of the bridge bearing body 2.

[0040] Then, the first semi-circular plate 41 and the second semi-circular plate 42 are placed on top of the pier 1 and fixed together with bolts to complete the installation of the lower protective plate 4. Next, the first connecting ring 51 and the second connecting ring 52 are fixed to the top of the first semi-circular plate 41 and the second semi-circular plate 42 respectively, and connected with bolts to install the upper protective plate 5. During the use of the bridge, when the beam 3 vibrates, the damping spring 62 and the damping rod 61 in the damping assembly 6 work together to absorb and dissipate vibration energy, reducing the vibration transmitted from the beam 3 to the bridge bearing body 2. At the same time, the buffer assembly 433 on the inner wall of the lower protective plate 4 will also provide secondary buffering for the vibration transmitted from the bridge bearing body 2, protecting the bridge bearing body 2. The support block outside the lower protective plate 4 always provides stable support for the lower protective plate 4, ensuring that the entire structure can operate stably under various working conditions and exert good dustproof and vibration reduction effects.
