[0002] A cylindrical pier is a columnar structure with a circular cross section. It is a common type of pier used in bridges. It is usually used to support the foundation or pier body of buildings such as bridges and pipelines. It mainly bears the gravity of the bridge itself and transmits it to the foundation through the foundation. In addition, the cylindrical pier also bears the horizontal and vertical forces on the bridge, making the entire bridge more stable. When choosing a cylindrical pier, it is necessary to make a reasonable choice based on factors such as the span, flow rate, and flow velocity of the bridge.

[0003] Cylindrical piers are an important part of bridge maintenance and safety. They are usually built with materials such as reinforced concrete or prestressed concrete. When the cylindrical piers are in use, they are generally set directly under the bridge to support the bridge. Since the cylindrical piers cannot be well protected during use, when the vehicles under the bridge collide with the cylindrical piers during driving, they will directly impact the surface of the cylindrical piers, which may easily cause wear on the surface of the cylindrical piers, or cause the corners of the cylindrical piers to break due to collision, resulting in cement splashing, which cannot well reduce the damage to the vehicles and the cylindrical piers, and is not conducive to extending the service life of the cylindrical piers. Therefore, in order to solve the above problems, a cylindrical pier protective layer is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a protective layer for cylindrical piers to solve the problem mentioned in the above background technology that the cylindrical piers cannot be well protected during use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] The cylindrical pier protective layer includes a pier body, the pier body includes a pier column 1, and the pier column 1 can be used to support the foundation or pier body of buildings such as bridges and pipelines, and is transferred to the foundation through the foundation;

[0024] A protection mechanism is provided on the surface of the pier column 1, and the protection mechanism includes a protection cover 2, which is sleeved on the surface of the pier column 1, and a fixing rod 21 is fixedly connected to the surface of the protection cover 2, and a sleeve rod 22 is movably connected to the surface of the fixing rod 21, and a protective plate 23 is fixedly connected to the surface of the sleeve rod 22, and a first spring 24 is fixedly connected to the end of the sleeve rod 22 away from the protective plate 23, and a rubber block 27 is fixedly connected to the inner surface of the protection cover 2. Through the arrangement of the protection cover 2 and the protective plate 23, the pier column 1 can be wrapped, and the direct impact of the vehicle on the pier column 1 can be avoided, thereby reducing the damage to the pier column 1, and the protection of the pier column 1 can be achieved, which is beneficial to extending the service life of the pier column 1.

[0025] Furthermore, the protection mechanism also includes a connecting rod 25, which is fixedly connected to the inner wall of the sleeve rod 22. A first movable groove 26 is provided on the inner side of the fixed rod 21. The connecting rod 25 moves on the inner side of the first movable groove 26. By setting the connecting rod 25 and the first movable groove 26, when the sleeve rod 22 is squeezed, the connecting rod 25 can move on the inner side of the first movable groove 26, and then the sleeve rod 22 can stably move on the surface of the fixed rod 21, so that the sleeve rod 22 is not easy to break.

[0026] Furthermore, the protective cover 2 is sleeved on the surface of the pier 1 in two groups, one end of the first spring 24 is fixedly connected to the protective cover 2, and the other end of the first spring 24 is fixedly connected to the sleeve rod 22. Through the setting of the first spring 24, when the vehicle collides with the protective plate 23, the impact caused by the collision can be absorbed to a certain extent, thereby reducing the transmission of the impact to the protective cover 2 and the pier 1, and better protecting the pier 1.

[0027] Furthermore, the fixing rods 21 are evenly distributed on the surface of the protective cover 2 in a circular array, and the rubber blocks 27 are evenly distributed on the inner surface of the protective cover 2 in a circular array. The provision of the rubber blocks 27 can further reduce the squeezing of the pier 1 by the protective cover 2 during collision, thereby providing a better protection effect on the pier 1. At the same time, direct contact between the protective cover 2 and the pier 1 can be avoided, and wear of the surface of the pier 1 by the protective cover 2 can be avoided.

[0028] Furthermore, a replacement mechanism is provided on the surface of the protective cover 2, and the replacement mechanism includes a connecting block 3, which is fixedly connected to the surface of the protective cover 2, a first plug rod 31 is fixedly connected to the surface of the connecting block 3, a second movable groove 32 is provided on the inner side of the connecting block 3, a second plug rod 33 is movably connected to the inner side of the second movable groove 32, a slot 34 is provided on the surface of the first plug rod 31, a second spring 35 is fixedly connected to the surface of the second plug rod 33, and a pull plate 36 is fixedly connected to the surface of the second plug rod 33. Through the setting of the pull plate 36, by pulling the pull plate 36, the second plug rod 33 will move under the action of the pull plate 36 and separate from the slot 34, so that it is convenient to remove the protective cover 2 from the pier 1 for replacement, which can ensure the protective effect of the protective cover 2 on the pier 1.

[0029] Furthermore, one end of the second spring 35 is fixedly connected to the second movable groove 32, and the other end of the second spring 35 is fixedly connected to the second plug rod 33. The three groups of second plug rods 33 and pull plates 36 are correspondingly connected. Through the setting of the second spring 35, the second plug rod 33 can be reset, and then the second plug rod 33 can be reset and engaged with the slot 34, so that the first plug rod 31 can be limited, which is convenient for the protective cover 2 to be sleeved on the pier 1 for protection.

[0030] Working principle: When in use, the protective cover 2 is sleeved on the surface of the pier column 1 to protect the surface of the pier column 1, so that when a collision occurs, the vehicle will not directly collide with the surface of the pier column 1, and the collision will first act on the protective plate 23. Under the action of the collision, the protective plate 23 will make the sleeve rod 22 move on the surface of the fixed rod 21, and at the same time, the connecting rod 25 moves inside the first movable groove 26. At this time, the first spring 24 is deformed, and the first spring 24 can alleviate the impact force during the collision to a certain extent, thereby reducing the impact on the protective cover 2 and the pier column 1, so that the protection effect is better. The setting of the rubber block 27 can further reduce the extrusion of the protective cover 2 on the pier column 1, thereby achieving a better protection effect;

[0031] By pulling the pull plate 36, the second rod 33 will move on the inner side of the second movable groove 32 under the action of the pull plate 36, and then the second rod 33 and the slot 34 will be separated, releasing the limit on the first rod 31. At this time, the second spring 35 is in a contracted state, and the first rod 31 can be pulled out from the connecting block 3, and the protective cover 2 can be removed from the surface of the pier 1 and replaced; when the replaced protective cover 2 needs to be used, the protective cover 2 is put on the surface of the pier 1, and the first rod 31 is inserted into the connecting block 3, and then the pull plate 36 is released, the second rod 33 will be reset under the rebound action of the second spring 35, and then the second rod 33 and the slot 34 are inserted into the first rod 31 to limit the position, so that the protective cover 2 can be fixed and replaced.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above.
