Road protective fence

Abstract

The invention discloses a road protective fence. The road protective fence comprises a base, a transverse rod, a fastening mechanism and a buffering mechanism. The base has a preset height in the vertical direction. The cross bar extends in the transverse direction. The fastening mechanism enables the cross rod to be installed on the base and enables the cross rod to move longitudinally. The buffering mechanism is installed on the transverse rod and elastically deforms when the transverse rod moves in the longitudinal direction. By the adoption of the road protective fence, after a foreign object collides with the transverse rods in the longitudinal direction, the transverse rods move longitudinally under the action of impact force and drive the buffering mechanisms to elastically deform for buffering, and therefore impact damage is reduced.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] In view of the problems existing in the prior art, it is urgent to develop a highway guardrail with good buffering performance, higher protection performance, convenient disassembly, easy replacement of damaged parts, and resource saving, so as to overcome the shortcomings in current practical applications and meet current needs. Figure 1-6 An embodiment of the present invention provides a highway guardrail, including a base 1, a crossbar 2, a fastening mechanism 3 and a buffer mechanism 4.

[0025] The bottom of the base 1 is set on the ground, and the base 1 has a preset height in the vertical direction, and is used to support the crossbar 2 above the ground. The number of the bases 1 can be two, and the two bases 1 are arranged at a distance in the horizontal direction, and are respectively set at the two ends of the crossbar 2. The base 1 can be made of galvanized steel pipe, so that it has good strength and a certain anti-rust function.

[0026] The bottom of the base 1 may have a fixing hole 101, the center line of which extends in the vertical direction for a bolt to pass through so as to fix the base 1 on the ground. The number of the fixing holes 101 may be multiple, such as four. The fixing holes 101 may be arranged at a preset distance around the bottom center of the base 1. The base 1 may have an installation cavity 102, the center line of which extends in the horizontal direction for the crossbar 2 to be inserted. The base 1 may include a square bottom plate 103 and a concave frame 104, and both ends of the concave frame 104 are fixed to the bottom plate.

[0027] The crossbar 2 extends in the lateral direction. Both ends of the crossbar 2 can be respectively inserted into the mounting cavities 102 of the two bases 1. The number of crossbars 2 is multiple, such as three. Each crossbar 2 can be arranged at a preset distance in the vertical direction. The crossbar 2 can be made of galvanized steel pipe, so that it has good strength and a certain anti-rust function.

[0028] The fastening mechanism 3 mounts the crossbar 2 on the base 1 and allows the crossbar 2 to move longitudinally.

[0029] The fastening mechanism 3 may include a connecting rod, which extends in the longitudinal direction and passes through the cross bar 2. The two ends of the connecting rod are respectively mounted on the first side wall and the second side wall of the mounting cavity 102 in the longitudinal direction, so that the cross bar 2 can slide longitudinally on the connecting rod. The connecting rod may include a latch 301 and a threaded rod 302. The first end of the latch 301 may have a stopper 3011, the second end of the latch 301 may have a threaded connection hole 3012, the stopper 3011 may be clamped on the first side of the base 1 in the longitudinal direction, and the second end of the latch 301 may pass through the first side wall and the cross bar 2. The first end of the threaded rod 302 may have a knob 3021, the knob 3021 may be clamped on the second side of the base 1 in the longitudinal direction, and the second end of the threaded rod 302 may pass through the second side wall and be screwed into the threaded connection hole 3012, so that the connecting rod can be detachably mounted on the base 1. Under the above conditions, the cross bar 2 is provided with a socket 201 for inserting the connecting rod.

[0030] The buffer mechanism 4 is mounted on the cross bar 2 and undergoes elastic deformation when the cross bar 2 moves longitudinally.

[0031] The buffer mechanism 4 may include a connecting column 101 and an elastic telescopic body. The connecting column 101 is arranged in the installation cavity 102 and is connected to the cross bar 2. The connecting column 101 may extend in the vertical direction. The connecting column 101 is arranged between two adjacent cross bars 2 and is connected to two adjacent cross bars 2. The elastic telescopic body is installed on both sides of the connecting column 101 in the longitudinal direction and contacts the first side wall and the second side wall. The number of elastic telescopic bodies may be multiple, such as five. Each elastic telescopic body may be arranged at a preset distance in the vertical direction. The elastic telescopic body may include a buffer rubber column 402 and / or a buffer spring 403. When the number of the elastic telescopic body is multiple and the elastic telescopic body includes a buffer rubber column 402 and a buffer spring 403, the buffer rubber column 402 and the buffer spring 403 are alternately arranged in the vertical direction.

[0032] The buffer mechanism 4 may further include a screw 404, which connects the connecting column 101 to the cross bar 2 so that the connecting column 101 is detachably connected to the cross bar 2. The screw 404 may be disposed on both sides of the top and bottom of the connecting column 101 in the lateral direction. Under the above conditions, the cross bar 2 is provided with a threaded mounting hole 202 for mounting the screw 404.

[0033] With the highway guardrail of the present invention, when a foreign object hits the crossbar 2, the crossbar 2 slides on the latch 301 under the impact force, and the sliding of the crossbar 2 drives the connecting column 101 to move. When the connecting column 101 moves in the base 1, it will squeeze the buffer rubber column 402 and the buffer spring 403 on one side, and the buffer rubber column 402 and the buffer spring 403 will deform to buffer, thereby reducing the impact damage; in addition, when it is damaged by the impact, the threaded rod 302 can be taken out of the threaded hole, and then the crossbar 2 is separated from the base 1, and then the screw 404 is unscrewed to separate the connecting column 101 from the crossbar 2, and then the damaged part is replaced, and the remaining intact parts continue to be installed and used. In summary, the present invention has good buffering performance and higher protection performance; it is easy to disassemble, and it is convenient to replace damaged parts separately, saving resources.
