[0030] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.
[0031] Example:
[0032] like Figure 1-Figure 5 As shown, a bridge pier anti-collision buffer device includes a main body 100 and an anti-collision plate 200;
[0033] The main body 100 includes an inner cage 101, an outer cage 102 and a plurality of connecting rods 103. The inner cage 101 and the outer cage 102 are coaxial and spaced apart. The inner cage 101 and the outer cage 102 are connected by the connecting rods 103. The inner cage 101 is fixedly connected to the bridge pier. An installation gap for installing the anti-collision plate 200 is formed between the inner cage 101 and the outer cage 102.
[0034] A plurality of anti-collision plates 200 are provided and inserted into the installation gap, and an elastic member is provided in each anti-collision plate 200 .
[0035] The bridge pier anti-collision buffer device forms an additional installation space on the bridge pier by installing the main body 100 on the bridge pier, so as to facilitate the installation of the anti-collision plate 200. The anti-collision plate 200 includes an elastic member. When a ship, floating objects on the water surface, etc. hit the anti-collision plate 200, due to the buffering effect of the elastic member, the anti-collision plate 200 absorbs the impact energy while bearing the impact, which can greatly reduce the impact force of the ship, floating objects on the water surface, etc. on the bridge pier. At the same time, the design of the anti-collision plate 200 can also prevent ships, floating objects on the water surface, etc. from directly hitting the hard part of the bridge pier, further protecting the bridge pier.
[0036] During operation, the staff first fixes the inner cage 101 on the bridge pier, and then connects the outer cage 102 through the connecting rod 103 to form the main body 100. Then insert the anti-collision plate 200 into the installation gap; at this point, the staff's installation work is completed. In the subsequent use process, the staff can perform maintenance on the bridge pier anti-collision buffer device.
[0037] Specifically, the collision will cause the bridge pier anti-collision buffer device to deform. If the impact force is small, generally, the outer cage 102 and / or the anti-collision plate 200 will be deformed, and the staff can repair the deformed parts. If the impact force is large, the deformation is large and even difficult to repair. At this time, the staff should replace it in time.
[0038] In this embodiment, the inner cage 101 includes a plurality of first annular bars and a plurality of first connecting rods. The plurality of first annular bars are coaxial and arranged at equal intervals along the axis. Each first annular bar is provided with a plurality of fixing parts for connecting to the piers. The first connecting rods are used to connect adjacent first annular bars to form a cage-like structure.
[0039] Based on the above design, the cage structure is a hollow structure, which reduces the weight and material usage of the inner cage 101, which helps to reduce the use cost, and is also convenient for step-by-step installation, which reduces the difficulty of subsequent replacement operations. The fixing parts can be any suitable commercially available equipment, including but not limited to steel hoops, with a wide range of choices and good practicality.
[0040] In this embodiment, the outer cage 102 includes a plurality of second annular bars and a plurality of second connecting rods, the plurality of second annular bars are coaxial and arranged at equal intervals along the axis, and the second connecting rods are used to connect adjacent second annular bars to form a cage-like structure. It is easy to understand that the structure of the outer cage 102 is the same as that of the inner cage 101, and the difference between the two is that the diameters are different. Based on this, the use cost is reduced.
[0041] Furthermore, in order to reduce the difficulty of the replacement operation, the first annular bar and the second annular bar can be made of steel bars bent into rings, and the two ends of the steel bars are abutted and welded, so as to form an annular bar through the steel bars.
[0042] In a possible implementation, the inner cage 101 includes a plurality of first annular bars that are coaxial and equally spaced along the axis, and the spacing between adjacent first annular bars is 30-50 cm.
[0043] In a possible implementation, the outer cage 102 includes a plurality of coaxial second annular bars arranged at equal intervals along the axis, and the spacing between adjacent second annular bars is 30-50 cm.
[0044] Based on the above design, according to actual work needs, the staff can arbitrarily adjust the spacing between adjacent first annular strips. Similarly, the staff can also arbitrarily adjust the spacing between adjacent second annular strips.
[0045] In this embodiment, the main body 100 forms a double-layer cage structure through an inner cage 101 and an outer cage 102. The double-layer cage structure is sleeved on the bridge pier, and the lower end of the double-layer cage structure is located 40-60 cm below the design water level, and the upper end of the double-layer cage structure is abutted against the cap beam of the bridge body.
[0046] Based on the above design, the main body 100 forms a double-layer cage structure, which is convenient for forming an installation gap to install the anti-collision plate 200, and also helps to improve the structural strength of the main body 100 and improve the anti-collision performance. After the main body 100 is installed, its stability is checked. After it meets the requirements, the anti-collision plate 200 is installed. And the design water level is the liquid level of the river, then the main body 100 extends from underwater to the bridge body, and the main body 100 fully covers the part of the bridge pier located on the water surface, leaving sufficient space for the installation of the anti-collision plate 200.
[0047] In this embodiment, the height of the anti-collision plate 200 is 50 cm, the width is 30-50 cm, and the thickness is 10-15 cm. Based on the above design, the width and thickness can be selected according to the anti-collision requirements, and the specifications of the anti-collision plate 200 are increased to facilitate the selection of the staff.
[0048] In this embodiment, the anti-collision plate 200 includes an inner plate 201, an outer plate 202 and a plurality of springs 203. The inner plate 201 and the outer plate 202 are arranged opposite to each other. The plurality of springs 203 are located between the inner plate 201 and the outer plate 202 and are used to connect the inner plate 201 and the outer plate 202. Accordingly, the plurality of springs 203 are configured as the elastic member. Based on the above design, the elastic force of the spring 203 is used to achieve buffering and impact absorption, thereby protecting the bridge pier. The inner plate 201 and the outer plate 202 are selected from any suitable existing plates to reduce the use cost.
[0049] It is easy to understand that the spring 203 has an extended state and a compressed state;
[0050] Accordingly, when the spring 203 is in the extended state, the anti-collision plate 200 is stretched open;
[0051] When the spring 203 is in a compressed state, the anti-collision plate 200 also includes a clamping strip 300 and a triangular buckle 400. The clamping strip 300 is used to connect the inner plate 201 and the outer plate 202. The triangular buckle 400 connects the inner plate 201 and the outer plate 202, and the triangular buckle 400 has a buckled state and a separated state. When the triangular buckle 400 is in the buckled state, the triangular buckle 400 cooperates with the clamping strip 300 to make the spring 203 in a compressed state. When the triangular buckle 400 is in the separated state, the spring 203 stretches and causes the anti-collision plate 200 to be stretched open.
[0052] Based on the above design, when the spring 203 is in an extended state, the anti-collision plate 200 is stretched open. When a ship, floating objects on the water surface, etc., hit the anti-collision plate 200, the spring 203 is compressed and deformed, thereby achieving buffering and impact absorption. When the spring 203 is in a compressed state, the anti-collision plate 200 overcomes the elastic force of the spring 203 through the clip strip 300 and the triangular buckle 400, thereby achieving connection and fixation, and also keeping the spring 203 in a compressed state. When a ship, floating objects on the water surface, etc. hit the anti-collision plate 200, the impact of the collision causes the anti-collision plate 200 to deform, so that the triangular buckle 400 changes from a buckled state to a separated state. The elastic force of the spring 203 is greater than the force of the clip strip 300, the spring 203 stretches, and the anti-collision plate 200 is stretched open, playing a role of buffering and shock absorption, thereby protecting the bridge pier from impact damage.
[0053] Accordingly, a plurality of clips 300 are provided, and the clips 300 located at the bottom are located 20-40 cm below the design water level. Optionally, during the installation of the bridge pier anti-collision buffer device, after calculating the positions of each anti-collision plate 200, the clips 300 can also be fixed to the outer cage 102 in advance, and the anti-collision plate 200 can be inserted into the installation gap before connecting the clips 300.
[0054] like Figure 5As shown, the triangular buckle 400 includes a ring body 401 and a hook 402. The ring body 401 is triangular and is provided with a notch 403. The hook 402 has two opposite ends, one end of which is rotatably connected to one end of the notch 403, and the other end is provided with a hook for connecting the ring body 401. Accordingly, the notch 403 is provided with a clamping column 404 adapted for the hook and a sliding groove 405 for the hook to slide.
[0055] Based on the above design, when the triangular buckle 400 is in the buckled state, the hook of the hook 402 is sleeved and abutted against the clamping column 404, thereby offsetting the elastic force of the spring 203. When a ship, floating objects on the water surface, etc. hit the anti-collision plate 200, the ring body 401 is deformed, the hook can slide along the slide groove 405 and separate from the clamping column 404, and the triangular buckle 400 is in a separated state; at this time, only the clamping strip 300 plays a connecting role, the elastic force of the spring 203 is greater than the force of the clamping strip 300, the spring 203 stretches, and the anti-collision plate 200 is stretched.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
