[0030] [First embodiment]

[0031] Reference Figure 1-6 The first embodiment provided by the present embodiment is shown, and the embodiment provides a steel frame bridge crash pier, including a pier body 1, and a protective device 2 is provided on the arc surface of the pier body 1. By providing the protective device, the airbags provided on the protective device can effectively protect the pier body, reduce the damage to the pier caused by the collision of ships and unexpected debris with the pier, and thus improve the strength and service life of the pier; an auxiliary device 3 is provided on the top of the protective device 2. By providing the auxiliary device, the reflective strips provided on the auxiliary device can remind ships and crew members in the river to pay enough attention, thereby reducing the possibility of ships colliding with the pier.

[0032] Reference Figure 3-4 As shown, the protective device 2 includes four fixing hooks 21, and the four fixing hooks 21 are fixedly connected to the arc surface of the pier body 1. The four fixing hooks 21 are distributed in a circle, and a dovetail groove 22 is provided on the surface of the fixing hook 21. An elastic member 23 is fixedly connected inside the fixing hook 21. The elastic member 23 can select a compression spring commonly used in the mechanical field to withstand axial pressure when the fixing buckle 26 is inserted into the dovetail groove 22. One end of the elastic member 23 is fixedly connected to a limiting plate 24. The fixing hook 21 is provided with a fixing buckle 26 by sliding through the dovetail groove 22. One side of the fixing buckle 26 is fixedly connected to an airbag 27. An inflation port is provided on the upper surface of the airbag 27. A rubber plug 28 is threadedly inserted into the airbag 27 by means of the inflation port. Opening the rubber plug 28 can realize inflation into the airbag 27 or discharge of the inflation inside the airbag 27. When in use, first move the airbag 27 to the fixed hook 21, insert the fixed buckle 26 of the airbag 27 into the dovetail groove 22 of the fixed hook 21, and then the fixed buckle 26 squeezes the limit plate 24, and the elastic member 23 on the limit plate 24 contracts. After the fixed buckle 26 moves past the limit plate 24, under the action of the resetting elastic force of the elastic member 23, the limit plate 24 clamps the fixed buckle 26, thereby achieving the effect of fixing the fixed buckle 26 and the airbag 27. Finally, inflate the airbag 27 through the air-inflation port, rotate the rubber plug 28, and the rubber plug 28 blocks the air-inflation port of the airbag 27. Preferably, a drawstring 29 is fixedly connected to one side of the rubber plug 28, and one end of the drawstring 29 is fixedly connected to the airbag 27. By setting the drawstring 29, the maximum displacement of the rubber plug 28 is limited, thereby preventing the rubber plug 28 from falling when not in use. The airbag 27 provided by the protective device 2 achieves the effect of protecting the pier body 1, reducing the damage to the pier caused by the collision of ships and unexpected debris, thereby improving the strength and service life of the pier.

[0033] Reference Figure 3-4As shown, two symmetrical telescopic rods 25 are fixedly connected to one side of the limit plate 24 close to the elastic member 23, and one end of the telescopic rod 25 is fixedly connected to the inner wall of the fixing hook 21. The moving direction of the limit plate 24 is limited by the telescopic rod 25, so as to prevent the limit plate 24 from moving in an unexpected track, thereby improving the stability of the movement of the limit plate 24.

[0034] Reference Figure 2 and Figure 4 As shown, two symmetrical slides 210 are fixedly connected to one side of the airbag 27, and a slide rail 211 is fixedly connected to the pier body 1 corresponding to the slide 210. The inner wall size of the slide rail 211 is adapted to the size of the slide rail 210. The slide 210 moves in the inner wall of the slide rail 211, and the installation position of the airbag 27 is restricted by the slide 210, so that the staff can install and position the airbag 27 conveniently.

[0035] Reference Figure 5-6 As shown, the auxiliary device 3 includes two symmetrical guide tubes 31, one end of the guide tube 31 is fixedly connected to the upper surface of the airbag 27, and a guide rod 32 is slidably provided at the end of the guide tube 31 away from the airbag 27. A reserved hole 34 is opened on the arc surface of the guide rod 32, and a bolt 33 is threadedly inserted at the guide tube 31 corresponding to the reserved hole 34. The size of the bolt 33 is adapted to the size of the reserved hole 34. The ends of the two guide rods 32 away from the guide tube 31 are fixedly connected to the same fixing plate 35, and a plurality of reflective strips 36 are fixedly connected to the surface of the fixing plate 35. First, move the fixing plate 35, and insert the two guide rods 32 at one end of the fixing plate 35 into the guide tube 31. When the reserved hole 34 of the guide rod 32 moves to the position of the bolt 33, turn the bolt 33, and the bolt 33 passes through the guide tube 31 and is inserted into the reserved hole 34 of the guide rod 32, thereby fixing the fixing plate 35 and the guide rod 32. The reflective strips provided on the auxiliary device can remind ships and crew members in the river to pay enough attention, thereby reducing the possibility of ships colliding with bridge piers.

[0036] Reference Figure 5-6 As shown, as a further preference, a handle 37 is fixedly connected to the upper surface of the fixing plate 35, and the surface of the handle 37 is provided with anti-slip grooves. The handle 37 is provided to facilitate the staff to move the fixing plate 35; and the end of the guide rod 32 close to the guide tube 31 is fixedly connected to a pointed protrusion 38, and the tip of the pointed protrusion 38 is away from the guide rod 32. The pointed protrusion 38 is provided to facilitate the staff to insert the guide rod 32 into the guide tube 31; in addition, one end of the bolt 33 is fixedly connected to two control blocks 39, and the two control blocks 39 are centrally symmetrical. The control block 39 is provided to increase the contact area between the staff's hand and the bolt 33, thereby facilitating the staff to hold the bolt 33 for rotation and locking, thereby facilitating operation.

[0037] The working process of this embodiment is:

[0038] The use process of the protective device is as follows: first, the airbag 27 is moved, the slide plate 210 on the airbag 27 is aligned with the slide rail 211, the slide plate 210 is inserted into the slide rail 211, and the fixing buckle 26 of the airbag 27 is moved to the fixing hook 21, and the fixing buckle 26 is inserted into the dovetail groove 22 of the fixing hook 21. At this time, the fixing buckle 26 squeezes the limit plate 24, and the elastic member 23 and the telescopic rod 25 on the limit plate 24 are contracted. When the fixing buckle 26 moves over the limit plate 24, under the action of the resetting elastic force of the elastic member 23, the limit plate 24 will be fixed. The fixing buckle 26 is stuck, which achieves the effect of fixing the fixing buckle 26 and the airbag 27. Finally, the airbag 27 is inflated through the inflation port, and the rubber plug 28 is rotated. The rubber plug 28 blocks the inflation port of the airbag 27, and the pull rope 29 on the rubber plug 28 achieves the effect of limiting the maximum displacement of the rubber plug 28. By providing a protective device, the airbag arranged on the protective device can achieve effective protection of the pier body, reduce the damage to the pier caused by the collision of ships and unexpected debris with the pier, and thus improve the strength and service life of the pier.

[0039] The use process of the auxiliary device is as follows: the staff first holds the handle 37 to move the fixing plate 35, and inserts the two guide rods 32 at one end of the fixing plate 35 into the guide tube 31 with the help of the pointed protrusion 38. When the reserved hole 34 of the guide rod 32 moves to the position of the bolt 33, the control block 39 is rotated, and the control block 39 carries the bolt 33 through the guide tube 31 and is inserted into the reserved hole 34 of the guide rod 32 to fix the fixing plate 35 and the guide rod 32. By providing the auxiliary device, the reflective strips provided on the auxiliary device can remind ships and crew members in the river to pay enough attention, thereby reducing the possibility of ships colliding with bridge piers.
