Description

Technical Field

[0001] The utility model belongs to the technical field of anti-collision piers, and in particular relates to an anti-collision pier for highway construction. Background Art

[0002] When a highway is being built or maintained, it is necessary to place some crash barriers around the construction site. On the one hand, they can prevent cars from accidentally entering the construction site, and on the other hand, they can isolate pedestrians and vehicles. Crash barriers can facilitate the normal progress of highway construction.

[0003] In the Chinese patent with publication number CN211690089U, a crash pier for highway construction is mentioned, which is provided with a buffer device and a buffer rubber pad. The inner side plate on the buffer device is fixedly installed on both sides of the plastic pier body by bolts, which can protect the plastic pier body and prevent the two sides of the plastic pier body from being damaged by friction or collision. Then the buffer spring and buffer rubber pad on the buffer device cooperate with the plastic pier body to buffer the impact force to the maximum extent and minimize the damage caused by the vehicle collision. However, the crash pier only relies on the buffer spring to deal with the impact force for shock absorption and buffering, and its effect is not ideal. This single shock absorption method is often difficult to achieve the expected buffering effect when facing a strong impact force, and the repeated rebound phenomenon of the buffer spring will also weaken the protective efficiency of the crash pier to a certain extent, affecting its overall anti-collision effect.

[0004] In addition, the isolation piers currently on the market, whether they are made of concrete or sand-filled crash barrels, all have a significant shortcoming, which is that they are not easy to move on site. When they need to be quickly adjusted or moved to meet different traffic or safety needs, these isolation piers are often bulky and difficult to operate, which undoubtedly increases the labor intensity of the staff and reduces work efficiency.

[0005] The utility model aims to provide a crash pier for highway construction to solve the problems raised in the above-mentioned background technology.

Furthermore, the anti-collision effect of the anti-collision pier can be strengthened, and the repeated rebound phenomenon of the buffer spring can be inhibited to enhance the protection efficiency of the anti-collision pier.

The movable plate is pushed downward by extending the electric telescopic rod, and the movable wheels can be extended from the storage groove to support the anti-collision pier.

DETAILED DESCRIPTION

[0023] 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.

[0024] Embodiment 1:

[0025] See also Figure 1 - Figure 4 As shown, a crash pier for highway construction includes:

[0026] A crash pier body 1, a plurality of buffer mechanisms 2 are fixedly connected to the outer wall of the crash pier body 1, a receiving groove 4 is provided in the middle of the lower end of the crash pier body 1, and a moving mechanism 5 is provided inside the receiving groove 4;

[0027] The buffer mechanism 2 includes a mounting plate 21, a buffer groove 22, a limiting groove 23, a buffer frame 24 and a damper 25. The mounting plate 21, the buffer groove 22 and the damper 25 are each provided with two, the buffer groove 22 is opened on the outer wall of the mounting plate 21, the limiting groove 23 is opened on the groove wall of the buffer groove 22, the buffer frame 24 is arranged between the two buffer grooves 22, and the damper 25 is fixedly installed between the two mounting plates 21.

[0028] Depend on Figure 1 and Figure 2 It can be known that the buffer frame 24 includes a buffer rod 241, a buffer slider 242, a buffer spring 243 and a limiting protrusion 244. There are two buffer rods 241, and there are four buffer sliders 242 and four buffer springs 243. The buffer slider 242 is movably connected to the outer sides of the two buffer rods 241 through a movable axis. The buffer spring 243 is fixedly connected to the outer side of the buffer slider 242, and the limiting protrusion 244 is arranged at the top and bottom ends of the buffer slider 242.

[0029] As can be seen from the above, first, when the anti-collision pad 3 is impacted, the impact force pushes the outer mounting plate 21 to move toward the anti-collision pier body 1, and then the buffer slider 242 slides in the buffer groove 22, and the limiting protrusion 244 slides and limits in the limiting groove 23, so that the X-shaped frame formed by the two buffer rods 241 is closed to perform preliminary buffering of the impact force, and then the elasticity of the buffer spring 243 can be used for buffering again, thereby effectively buffering and shock absorbing the impact force, which can enhance the anti-collision effect of the anti-collision pier, and finally, in combination with the damping characteristics of the damper 25, the repeated rebound phenomenon of the buffer spring 243 can be suppressed, which can enhance the protective effectiveness of the anti-collision pier body 1.

[0030] Specifically, refer to Figure 2 and Figure 3 As shown, the middle parts of the opposite surfaces of the two buffer rods 241 are movably connected to form an X-shaped movable frame through a movable shaft, and the limiting protrusion 244 is slidably connected to the limiting groove 23.

[0031] As can be seen from the above, the X-shaped movable frame composed of the two buffer rods 241 can effectively buffer the external impact force, which can further enhance the anti-collision effect. The limiting protrusion 244 slides in the limiting groove 23 to limit the position of the buffer slider 242.

[0032] Embodiment 2:

[0033] refer to Figure 1 and Figure 4As shown in the figure, anti-collision pads 3 are fixedly connected between the outer sides of several front buffer mechanisms 2 and between the outer sides of several rear buffer mechanisms 2. An avoidance groove 6 is formed on the outer side of the anti-collision pier body 1 away from the buffer mechanism 2, and a control button 7 is fixedly connected to the inner groove wall of the avoidance groove 6; The moving mechanism 5 includes an electric telescopic rod 51, a moving plate 52, a limiting rod 53, a limiting frame 54 and moving wheels 55. There are two electric telescopic rods 51, and the upper ends of the two electric telescopic rods 51 are fixedly connected to the upper groove wall of the storage groove 4 in an inserted manner. The moving plate 52 is fixedly connected to the top end of the electric telescopic rod 51. The limiting rod 53 is inserted and movably connected to the top end of the moving plate 52. The limiting frame 54 is fixedly connected to the bottom end of the limiting rod 53. The moving wheels 55 are fixedly connected to the bottom end of the moving plate 52.

[0034] As can be seen from the above, when it is necessary to move the position of the anti-collision pier body 1, the electric telescopic rod 51 can be controlled to start through the control button 7, so that the electric telescopic rod 51 extends to push the moving plate 52 downward, and the moving plate 52 is guided and limited by the storage groove 4 and the limiting rod 53, so that the moving plate 52 drives the moving wheels 55 to move downward and extend out of the storage groove 4, so that the moving wheels 55 contact the ground and support the anti-collision pier body 1. Then, the position of the entire anti-collision pier can be quickly adjusted or moved through the extended moving wheels 55, which is convenient for operating these heavy isolation piers, and can thus meet different traffic or safety requirements, reduce the labor intensity of the staff, and improve work efficiency.

[0035] Specifically, referring to Figure 4 As shown in the figure, the electric telescopic rod 51 is set as a multi-stage telescopic structure, and the electric telescopic rod 51 is electrically connected to the control button 7. The limiting frame 54 is set as a "Feng" character structure, and the bottom end surface of the limiting frame 54 is flush with the bottom end surface of the anti-collision pier body 1.

[0036] As can be seen from the above, the multi-stage electric telescopic rod 51 has a large telescopic range, and it is convenient to flexibly control the telescopic of the electric telescopic rod 51 through the control button 7, so that the limiting frame 54 can contact the ground together with the anti-collision pier body 1 for support and play a limiting role on the moving plate 52.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
