Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a novel highway guardrail that is easy to maintain. Background Art

[0002] Expressways are high-grade roads that are designed specifically for cars to travel at high speeds in separate lanes and with full access control. Guardrails are indispensable in the construction of expressways. The installation of guardrails can absorb energy when high-speed vehicles collide with them, making them less likely to be destroyed, and at the same time provide good protection for vehicles and drivers and passengers.

[0003] However, most of the existing highway guardrails are fixed by bolts during installation. When the guardrail needs to be repaired or replaced, the disassembly and assembly of the guardrail fixed by bolts is cumbersome, time-consuming and labor-intensive, and the maintenance time is long, which causes the lane to narrow, affects the normal operation of the road, and causes road congestion. Secondly, when the guardrail is installed only by bolts, the bolts fixing the guardrail are prone to loosening over time, resulting in poor stability of the guardrail and reducing the safety of highway driving. In view of the above problems, the inventor proposes a new type of easy-to-maintain highway guardrail to solve the above problems. Utility Model Content

[0004] In order to solve the problem that most of the existing highway guardrails are fixed by bolts during installation, and when the guardrails need to be repaired or replaced, the guardrails fixed by bolts are complicated to disassemble and assemble, time-consuming and labor-intensive, and the maintenance time is long; the purpose of the utility model is to provide a new type of highway guardrail that is easy to maintain.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a new type of highway guardrail that is easy to maintain, including fixed rods, the number of fixed rods is two, the top ends of the two fixed rods are fixedly installed with support seats, the top ends of the two support seats are fixedly installed with connecting seats, the number of connecting seats is two, a guardrail is detachably installed between the two connecting seats, both ends of the guardrail are fixedly installed with fixing parts, both ends of the guardrail are symmetrically provided with card slots, the fixing parts are slidably carded in the card slots, the top surface of the fixing parts is detachably installed with a fixing cover, a positioning assembly is installed in the middle of one end of the connecting seat, the positioning assembly includes a reset spring, both ends of the reset spring are fixedly installed with sliders, the number of sliders is two, one end of the two sliders is fixedly installed with a limit pin, the limit pin is slidably inserted into one side of the fixed cover through the reset spring and the slider, and the fixed cover and the positioning assembly cooperate with each other;

[0006] The installation limit of the guardrail is completed by two connecting seats installed on the top of two adjacent fixing rods in cooperation with the fixing parts installed on both sides of the guardrail. After the limit is completed, the guardrail is fixed by the fixing cover in cooperation with the positioning assembly. When the guardrail needs to be disassembled, the limit pin is pulled out from the fixing cover of the corresponding guardrail with the cooperation of the reset spring and the slider, and the fixing cover is removed from the fixing part to complete the disassembly of the guardrail. The cooperation between the fixing cover and the positioning assembly makes it easy to disassemble, assemble and replace the guardrail without the need to install and fix it by bolts, thus saving time and effort.

[0007] Preferably, a positioning pin is fixedly installed on the bottom surface of the slot, and the fixing piece is slidably inserted on the surface of the positioning pin, the positioning pin and the fixing piece cooperate with each other, and a damping strip is symmetrically installed on the bottom surface of the fixing cover, and a damping groove is symmetrically opened on the top surface of the fixing piece, and the damping strip is dampingly inserted in the damping groove, and the damping strip and the damping groove cooperate with each other. When the fixing pieces installed at both ends of the guardrail are clamped in the slots corresponding to the connecting seat, the positioning pin is used to complete the limited fixation of the fixing piece in the slot. When the fixing piece is fixed by the fixing cover, the two damping strips installed on the bottom surface of the fixing cover cooperate with the two damping grooves opened on the top surface of the fixing piece to increase the firmness of the fixing piece after the fixing cover is fixed. Through the above operation, the stability of the guardrail after installation is increased, which solves the problem that the existing guardrail is prone to loosening over time when it is installed only by bolts, resulting in poor stability of the guardrail and reduced driving safety on the highway.

[0008] Preferably, a positioning strip is fixedly installed on one side of the fixed cover, and a positioning slot is provided on one end of the card slot. The positioning strip is slidably inserted in the positioning slot, and the positioning strip and the positioning slot cooperate with each other. When the corresponding fixing piece is fixed by the fixed cover, when the positioning strip installed on one end of the fixed cover is completely inserted into the positioning slot, the fixed cover is installed. With the cooperation of the positioning strip and the positioning slot, the stability of the fixed cover after installation is increased. A connecting buckle is fixedly installed on one side of the surface of the two sliders, and a push-pull buckle is fixedly installed on one side of the two connecting buckles. One side of the two push-pull buckles slide relatively on the surface of one side of the connecting seat, and the connection and fixation of the two sliders and the two push-pull buckles are respectively completed by the two connecting buckles. With the cooperation of the push-pull buckle and the connecting buckle, the two sliders are controlled to drive the two limit pins to be plugged in and out of one side of the fixed cover, thereby completing the fixing and separation of the fixed cover.

[0011] 1. In the utility model, the installation limit of the guardrail is completed by two connecting seats installed at the top of two adjacent fixing rods and the fixing pieces installed on both sides of the guardrail. After the limit is completed, the guardrail is fixed by the fixing cover and the positioning assembly. When the guardrail needs to be disassembled, the limit pin is pulled out from the fixing cover of the corresponding guardrail under the cooperation of the reset spring and the slider, and the fixing cover is removed from the fixing piece to complete the disassembly of the guardrail. The cooperation between the fixing cover and the positioning assembly facilitates the disassembly and replacement of the guardrail, and there is no need to install and fix it by bolts, which saves time and effort.

[0023] The two connecting seats 2 installed at the top of the two adjacent fixing rods 1 cooperate with the fixing parts 31 installed on both sides of the guardrail 3 to complete the installation limit of the guardrail 3. After the limit is completed, the fixing cover 4 cooperates with the positioning assembly 5 to complete the fixation of the guardrail 3. When the guardrail 3 needs to be disassembled, with the cooperation of the reset spring 51 and the slider 52, the limit pin 53 is pulled out from the corresponding fixing cover 4 of the guardrail 3, and the fixing cover 4 is removed from the fixing part 31 to complete the disassembly of the guardrail 3. The cooperation between the fixing cover 4 and the positioning assembly 5 makes it easy to disassemble and replace the guardrail 3 without the need to install and fix it by bolts, saving time and effort.
