[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0031] Reference Figure 1 The utility model provides an embodiment: a shock absorbing component of a steel structure overpass, including an overpass body 1, a bridge pier 2 is fixedly connected to the bottom of the overpass body 1, and the bridge pier 2 is symmetrically distributed in two groups, and the bridge pier 2 plays a stable support and fixing effect on the overpass body 1, and a buffer component 3 is arranged on the bridge pier 2, and the impact force on the bridge pier 2 is reduced by the buffer component 3, thereby improving the buffer effect of the overpass, and an installation component 4 is arranged on the buffer component 3, and the installation component 4 facilitates the installation and disassembly of the buffer plate 31, thereby achieving the effect of facilitating the replacement of the buffer plate 31.

[0032] Reference Figure 2-Figure 4The buffer assembly 3 includes a buffer plate 31, and the buffer plates 31 are symmetrically distributed in two groups. The impact force received by the bridge pier 2 is transmitted to the hinged rod 37, the damping strip 32 and the movable column 35 through the buffer plate 31. The back of the buffer plate 31 is hinged with a hinged rod 37, and the impact force received is transmitted to the elastic telescopic rod 33 through the hinged rod 37. The rear end of the hinged rod 37 is hinged with the elastic telescopic rod 33. The elastic telescopic rod 33 is formed by two sets of sleeve rods sleeved together, which has the effect of contraction and extension, and the two sets of sleeve rods are provided with a composite A spring is arranged in position, and part of the impact force is reduced by an elastic telescopic rod 33. A damping strip 32 is fixedly connected to the front inner wall of the pier 2. The damping strip 32 slows down the movement speed of the buffer plate 31 when it is impacted, thereby reducing the impact force on the buffer plate 31. A groove 38 is opened on the front inner wall of the sleeve rod pier 2. The inner wall of the groove 38 is elastically connected to a movable column 35 through a spring 36. Through the elastic force of the spring 36, the movable column 35 always keeps sliding in the direction close to the buffer plate 31 without being affected by external force.

[0033] Reference Figure 2 and Figure 5 The mounting assembly 4 includes a clamping block 41, and the outer wall of the clamping block 41 is elastically connected to the inner wall of the movable column 35 through a limit spring 42. Through the elastic force of the limit spring 42, the clamping block 41 always maintains the clamping effect with the clamping groove 44 when not affected by external force, and the ring 43 is limited so that the buffer plate 31 remains fixedly installed on the movable column 35. The front side of the buffer plate 31 is fixedly connected with the ring 43. The fixing effect of the ring 43 prevents the ring 43 from falling off, and the outer wall of the ring 43 is provided with a clamping groove 44.

[0034] Reference Figure 1 and Figure 3 The outer periphery of the buffer plate 31 is slidably connected to the front inner wall of the pier 2. When the buffer plate 31 is impacted, a sliding effect is generated to transmit the impact force. The right side of the elastic telescopic rod 33 is fixedly connected with a fixing block 34. The back side of the fixing block 34 is fixedly connected to the front inner wall of the pier 2. The fixing effect of the fixing block 34 keeps the elastic telescopic rod 33 fixed to prevent it from falling off.

[0035] Reference Figure 3 One end of the spring 36 is fixedly connected to the inner wall of the groove 38, and the other end of the spring 36 is fixedly connected to the back of the movable column 35. Through the fixing effect of the spring 36, the spring 36 remains fixed to prevent the spring 36 from deflecting when it is squeezed.

[0036] Reference Figure 5The outer wall of the movable column 35 is plugged into the inner wall of the ring 43. Through the plug-in effect of the movable column 35 and the ring 43, the buffer plate 31 is fixedly installed on the movable column 35. One end of the limit spring 42 is fixedly connected to the inner wall of the movable column 35, and the other end of the limit spring 42 is fixedly connected to the outer wall of the block 41. Through the fixing effect of the limit spring 42, the block 41 is kept fixed to prevent the block 41 from falling off.

[0037] Reference Figure 1 The outer periphery of the movable column 35 is slidably connected to the inner wall of the buffer plate 31, and the outer periphery of the movable column 35 is slidably connected to the inner wall of the groove 38. Through the sliding effect of the movable column 35, the impact force is transmitted to the spring 36, so that the spring 36 reduces part of the impact force on the buffer plate 31.

[0038] Reference Figure 5 The outer wall of the block 41 is slidably connected to the inner wall of the movable column 35. Through the sliding effect of the block 41, the block 41 and the slot 44 are engaged or released. The outer wall of the block 41 is engaged with the inner wall of the slot 44. Through the engagement effect of the block 41 and the slot 44, the movable column 35 limits the ring 43.

[0039] Working principle: When vehicles or objects passing by the overpass hit the two sides of the pier 2, the impact force is transmitted to the hinged rod 37 through the buffer plate 31, and the impact force is transmitted to the elastic telescopic rod 33 through the hinged rod 37. The elastic force of the elastic telescopic rod 33 reduces part of the impact force on the buffer plate 31.

[0040] The impact force is transmitted to the damping strip 32 and the movable column 35 via the buffer plate 31. The damping strip 32 slows down the movement speed of the buffer plate 31 when it is impacted, thereby reducing a portion of the impact force received by the buffer plate 31. The impact force is transmitted to the spring 36 via the movable column 35. The elastic force of the spring 36 further reduces a portion of the impact load received by the buffer plate 31, thereby reducing the impact load received by the bridge pier 2 and improving the buffering effect of the overpass body 1.

[0041] When the buffer plate 31 is damaged by impact, the staff presses the block 41 to release the clamping effect with the slot 44, and at the same time releases the limiting effect on the ring 43, and releases the plug-in effect of the ring 43 and the movable column 35, so that the buffer plate 31 is disassembled, and the staff plugs the ring 43 set on the replaced buffer plate 31 into the movable column 35, so that the block 41 is clamped with the slot 44 under the elastic force of the limiting spring 42, and the ring 43 is limited, so that the replaced buffer plate 31 is fixedly installed on the movable column 35.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
