The first corrugated guardrail plate and the second corrugated guardrail plate are fixedly arranged on the anti-blocking block unit; the anti-blocking block unit includes a first anti-blocking block and a second anti-blocking block. The columns, guardrail plates, anti-blocking blocks, column caps, bolts and other components of the combined three-wave corrugated guardrail of this application are highly versatile, easy to process, and convenient for large-scale production and construction. At the same time, they can be used for upgrading, renovating and improving the existing old-style two-wave anti-collision guardrails on expressways and other grades of roads to enhance the protection capability. The above guardrails have construction protection but cannot be combined, so that the connection between guardrails is limited during large-scale construction, and the guardrails cannot be moved, making it inconvenient to move and requiring manual transportation. Therefore, a combined guardrail for highway construction is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a combined guardrail for highway construction, aiming to improve the existing technology that the guardrail can be combined through a connecting mechanism, so that the guardrails can be connected to each other during construction over a larger range, thereby facilitating the protection of the construction range, and the guardrail can be moved through a moving mechanism, so that it does not require manual handling during movement, and the burden on construction personnel can be reduced.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined guardrail for highway construction, including a guardrail, a driving assembly is arranged at the lower part of the guardrail, a moving assembly is arranged at the lower part of the guardrail, a connecting head is fixedly connected to the middle part of the left side of the guardrail, a fixing cylinder is fixedly connected to the middle part of the right side of the guardrail, a fixing block is fixedly connected to the upper inner part of the fixing cylinder, a screw is slidably connected inside the fixing block, a spring 1 is fixedly connected to the bottom left side of the fixing block, a moving block is fixedly connected to the bottom of the spring 1, and a base is fixedly connected to the bottom of the guardrail.

[0006] Furthermore, the driving assembly includes a motor, which is fixedly connected to the right side of the base, and the motor driving end is fixedly connected to a bidirectional threaded rod, and both sides of the bidirectional threaded rod are threadedly connected to sliders, and the sliders are slidably connected to connecting rods on the opposite sides.

[0007] Furthermore, the moving assembly includes a rotating shaft, which is fixedly connected to both sides of the base, the bottom of the rotating shaft is rotatably connected to a support rod, the bottom of the support rod is rotatably connected to a movable shaft, and both ends of the movable shaft are rotatably connected to pulleys.

[0008] Furthermore, two sleeves are fixedly connected to the top of the guardrail.

[0009] Furthermore, two insert rods are slidably connected inside the two sleeves.

[0010] Furthermore, light warning signs are fixedly connected to the tops of the two insertion rods.

[0011] Furthermore, a second spring is fixedly connected inside the insertion rod.

[0012] Furthermore, a push rod is fixedly connected to the right side of the second spring.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the screw rod is rotated in the fixed block and the movable block by using a twisting tool to make the thread on the screw rod disengage from the movable block. At this time, the movable block that is no longer fixed is bounced open by the elastic force of a spring, and the guardrail is inserted into the fixed cylinder on the other guardrail through the connecting head, and then aligned with the groove on the fixed block, and then the screw rod is twisted again to twist the movable block into the fixed cylinder until the groove on the movable block fixes the connecting head. Through the above, it is realized that the guardrail can be combined, so that the guardrails can be connected when a large-scale construction is carried out, which is convenient for protecting the construction range.

[0015] 2. In the utility model, when the guardrail needs to be moved, the motor is started to drive the bidirectional threaded rod to rotate, and the sliders on both sides of the bidirectional threaded rod move outward, thereby driving the connecting rod and the movable shaft. At this time, the support rod moves accordingly until the pulley is extended until it touches the ground. When the guardrail is fixed without moving, the motor is driven in reverse to retract the pulley into the base, and the base is fixed to the ground. The above method realizes that the guardrail can be moved, so that it does not need manual handling when moving, and the construction personnel can be reduced in burden.
