Description

Technical Field

[0001] The utility model relates to the technical field of highway construction equipment, in particular to a buffer and anti-collision barrel for highway construction. Background Art

[0002] Traffic safety is always a crucial issue in highway construction and daily operations. In order to reduce the incidence of traffic accidents and mitigate the damage caused by accidents, various traffic facilities such as crash barrels are widely used in areas prone to collisions, such as road turns, toll booths, elevated road entrances and exits, parking lots, etc. However, most existing crash barrels are hollow shell structures, which often have many deficiencies when facing vehicle collisions and are difficult to achieve ideal buffering effects.

[0003] Most of the existing crash barrels adopt a hollow shell design. After encountering a vehicle collision, they are easily severely deformed or even shrunken due to the impact force, and cannot maintain their original shape and protection capabilities. At the same time, due to structural limitations, these crash barrels are difficult to form an effective protective layer between the impact object and the wall, and cannot fully disperse and absorb the impact force generated by the collision, causing the impact object to directly act on the wall or other fixed facilities, aggravating the degree of damage. In addition, when the crash barrel with a hollow shell structure is hit, it is unable to offset and disperse the impact force well, so that most of the energy generated by the impact is directly transmitted to the impacted object, resulting in a significant reduction in the buffering effect of the crash barrel. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a buffer crash bucket for highway construction. Through this design, the problem that the existing crash bucket is easily deflated after being hit, resulting in poor buffering effect and impact resistance of the crash bucket is effectively solved.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1

[0020] Please refer to the attached Figure 1-4 The present embodiment is a buffer and anti-collision barrel for highway construction: it includes a fixed seat 1, to which a hollow outer barrel body 2 is fixedly connected, an identification strip 3 and a card slot 4 are arranged on the outside of the outer barrel body 2, a buffer sleeve 5 is sleeved in the card slot 4, a barrel mouth 6 is opened at the upper end of the outer barrel body 2, a barrel cover is arranged at the barrel mouth 6, a fixed column 8 is arranged below the barrel mouth 6, the bottom of the fixed column 8 is fixedly connected to the fixed seat 1, and a hollow buffer pad 9 is arranged between the fixed column 8 and the outer barrel body 2.

[0021] The diameter of the fixing seat 1 is larger than the diameter of the outer barrel body 2. The bottom of the fixing seat 1 is a rough horizontal surface. The outer barrel body 2 is made of rubber. There are two card slots 4 on the outer barrel body 2. The identification strip 3 is located on the outer barrel body 2 between the two card slots 4. The identification strip 3 is made of reflective material. The identification strip 3 serves as a reflective warning. Fillers can be added to the outer barrel body 2 from the barrel mouth 6 to increase the overall weight of the device and increase the stability of the device when placed. The barrel mouth 6 is tightly connected to the barrel cover 7, and the seal of the barrel cover 7 prevents the gas in the outer barrel body 2 from overflowing. In the event of a collision, the internal pressure of the outer barrel body 2 increases after being squeezed and deformed, which can have a good buffering effect on the impact. At the same time, the outer barrel body 2 and the buffer sleeve 5 are columnar structures as a whole. In the event of a collision, the arc-shaped contact surface can decompose the acting force to achieve a better unloading effect. The buffer sleeve 5 is clamped on the card slot 4, and the buffer sleeve 5 can be disassembled and replaced later to facilitate subsequent maintenance of the device.

[0022] A semi-cylindrical buffer strip 10 is fixedly connected to the outside of the buffer sleeve 5, and cavities are provided in the buffer strip 10 and the buffer sleeve 5; the buffer sleeve 5 is an inflatable structure, and the buffer strip 10 is a semi-cylindrical structure protruding outward. The buffer strip 10 protrudes outward relative to the outer barrel body 2, and in the event of a collision, it first collides with the buffer strip 10 and the buffer sleeve 5, and the buffer strip 10 and the buffer sleeve 5 play a role of pre-buffering.

[0023] A fixing groove 11 is provided at the upper end of the outer barrel body 2, and a warning block is slidably connected in the fixing groove 11. A warning light 12 is installed on the warning block, and a handle 13 is fixedly connected to the upper end of the outer barrel body 2; four grooves are provided at the upper end of the outer barrel body 2, and fixing grooves 11 are provided in two grooves on the front and rear sides, and the fixing grooves 11 are used to fix the warning block, the solar panel is on the rear side of the warning block, and the warning light 12 is on the front side of the warning block. When needed, the warning block can be stuck in the fixing groove 11, and the bright light of the warning light 12 can serve as a warning to pedestrians and vehicles when the visibility conditions are poor.

[0024] The buffer pad 9 is a vortex structure, the inner side of the buffer pad 9 is fixedly connected to the fixing column 8, and the outer side of the buffer pad 9 is fixedly connected to the inner wall of the outer barrel body 2; the buffer pad 9 can be a vortex structure, the outer side of the buffer pad 9 has an outward elastic force on the outer barrel body 2, the inner side of the buffer pad 9 is connected to the fixing, and the vortex-shaped buffer pad 9 has a filling and supporting effect on the interior of the outer barrel body 2. During a collision, the vortex-shaped buffer pad 9 can squeeze the gap in the middle to avoid the overall rigidity of the device being too strong. At the same time, compared with a hollow crash bucket, the addition of the buffer pad 9 can enable the crash bucket to offset a greater impact force under the same deformation amount, thereby preventing the crash bucket from being easily crushed.

[0025] The buffer pad 9 includes a plurality of support rods 14, which are equiangularly distributed around the fixed column 8, and a reinforcement sleeve 15 is fixedly connected to the support rod 14; the buffer pad 9 can also be composed of the support rod 14 and the reinforcement sleeve 15, and the support rod 14 is supported twice by the reinforcement sleeve 15. At the same time, leakage holes are set between the intermittently distributed support rods 14 and the reinforcement sleeve 15, which do not affect the addition of fillers such as water or sand into the outer barrel body 2. At the same time, the support effect on the outer barrel body 2 is increased without increasing the filler, thereby improving the impact force that the outer barrel body 2 can withstand. Example 2

[0026] The structure is the same as the above embodiment. Figure 5 As shown, the specific difference of this embodiment is that the barrel cover 7 is threadedly connected to the barrel mouth 6, a piston rod 16 is fixedly connected to the bottom of the barrel cover 7, a piston cavity 17 cooperating with the piston rod 16 is provided in the fixed column 8, and an air outlet 18 connected to the piston cavity 17 is provided at the bottom of the fixed column 8.

[0027] The fixing column 8 is a hollow structure, and the barrel cover 7 is fixedly connected to the barrel mouth 6. When the barrel cover 7 is fixed, the piston rod 16 at the lower end of the barrel cover 7 will penetrate into the piston chamber 17. As the piston rod 16 and the barrel cover 7 fall, the air in the piston chamber 17 enters the barrel body from the air outlet 18 at the lower end, so that the air pressure of the outer barrel body is improved to a certain extent. When an impact is received, the higher air bag inside the outer barrel body 2 can have a better cushioning effect on the impact, thereby improving the cushioning effect of the device on the impact.

[0028] 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.
