Description

Technical Field

[0001] The present application relates to the technical field of railway bridge construction, and in particular to a cap protection device for railway bridge construction. Background Art

[0002] The cap refers to a reinforced concrete platform connected to the top of each pile, which is set on the top of the pile foundation to bear and distribute the load transmitted by the pier body. The cap is the connecting part between the pile and the column or pier. The cap connects several or even more than a dozen piles to form a pile foundation. The cap is divided into high pile cap and low pile cap.

[0003] In the process of railway bridge construction, it is necessary to build pedestals in some special terrains, and the pedestals built inside the river channel will be hit by the running ships in the river channel, which will cause damage to the pedestals. Therefore, we proposed a pedestal protection equipment for railway bridge construction. Utility Model Content

[0027] Figure 1 The overall structure diagram provided for the embodiment of the present application;

[0028] Figure 2 A cross-sectional structural diagram provided for an embodiment of the present application;

[0029] Figure 3 This is an overall structural diagram of the buffer column provided in an embodiment of the present application.

[0030] like Figure 1-3 As shown, the embodiment of the present application provides a cap protection device for railway bridge construction, including:

[0031] A support body 1, the outer side of the support body 1 is sleeved with a protective tube 2, the outer side of the protective tube 2 is movably sleeved with a sleeve 4, and the outer side of the sleeve 4 is sleeved with an elastic buffer layer 5, and the outer side of the elastic buffer layer 5 is sleeved with a protective outer tube 3;

[0032] Buffer columns 6, which are placed in a circular array and rotated in a limited manner inside a placement groove 7 opened on the outside of the protective outer tube 3;

[0033] The end of the buffer column 6 close to the bottom end of the support platform body 1 is fixedly connected with a floating block 8.

[0034] Specifically: the overall structure consisting of the protective tube 2, the protective outer tube 3, the sleeve 4 and the elastic buffer layer 5 can also be divided into two parts, namely two halves, so as to facilitate the replacement or installation of the equipment;

[0035] The buffer column 6 is embedded in the placement groove 7 and will not fall out of the placement groove 7;

[0036] The shape of the support body 1 can be any shape, and the inner shape of the protection tube 2 and the outer shape of the support body 1 are mutually engaged or matched.

[0037] like Figure 3 As shown, a plurality of floating bars 10 are fixedly embedded in the inner and outer sides of the buffer column 6 in a circular array.

[0038] Specifically, the floating bar 10 can increase the buoyancy of the buffer column 6 .

[0039] like Figure 2 As shown: the inner side wall of the placement groove 7 is evenly inlaid with a plurality of balls 9.

[0040] Specifically, the ball 9 can make the buffer column 6 move up and down more smoothly.

[0041] like Figure 1 As shown in FIG. 1 , the length of the placement groove 7 is greater than the sum of the lengths of the buffer column 6 and the floating block 8 .

[0042] Specifically, the length limitation enables the buffer column 6 and the floating block 8 to move up and down inside the placement groove 7 as a whole, thereby meeting the water level of the river in different seasons.

[0043] like Figure 1 As shown: the outer cross-section of the protective outer tube 3 is circular.

[0044] Specifically: The circle can effectively buffer external impact forces.

[0045] like Figure 1 and Figure 2As shown: the inner side of the protection tube 2 is provided with four corresponding bayonet holes in a circular array, and the bayonet holes are correspondingly connected to the four outer corners of the support body 1.

[0046] Specifically, the bayonet can ensure stable installation of the protection tube 2 .

[0047] like Figure 1 As shown in FIG. 1 , the outer diameter of the floating block 8 is smaller than the outer diameter of the buffer column 6 .

[0048] Specifically, the limitation of the outer diameter can protect the buoy 8 , thereby preventing the buoy 8 from being damaged by collision with a ship.

[0049] The present application is applicable to the protection of the platform body 1 located inside the river channel, so as to protect the platform body 1 from being damaged by ships traveling in the river channel, that is, the overall structure composed of the protection pipe 2, the protection outer pipe 3, the sleeve 4 and the elastic buffer layer 5 is sleeved on the outer side of the platform body 1 to form a protective layer for the outer side of the platform body 1;

[0050] And the whole formed by the buffer column 6 and the floating block 8 is located inside the placement groove 7. Through the limitation of the placement groove 7, the buffer column 6 and the floating block 8 can float up and down with the water level, so that the buffer column 6 and the floating block 8 are always located on the water surface. In this way, when the ship collides with the protective outer tube 3, the arc on the surface of the platform body 1 will cause the ship's running direction to deviate toward the outside of the platform body 1, and the buffer column 6 can be rotated to further accelerate the deviation of the ship's running direction toward the outside of the platform body 1, which can efficiently buffer and unload the impact force of the ship and effectively protect the platform body 1.

[0051] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
