Description

Technical Field

[0001] This utility model relates to the field of support template technology, specifically a support template for repairing damage to concrete crash barriers. Background Technology

[0002] In highway bridge engineering, NJ-type reinforced concrete wall-type guardrails (commonly known as crash barriers) are a common safety protection structure. Crash barriers not only need to meet impact resistance requirements but also need to ensure a straight and smooth appearance to guarantee driving safety and aesthetics. However, during construction or subsequent maintenance, crash barriers may experience damage, cracks, or partial collapse, requiring repair.

[0003] Existing support templates for repairing damaged concrete crash barriers are not convenient for providing reflective warnings to passersby and vehicles during nighttime repairs, nor are they convenient for positioning and reinforcing the damaged areas during the repair support process. Therefore, this utility model provides a support template for repairing damaged concrete crash barriers. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a support template for repairing damaged concrete crash barriers, thus solving the problems mentioned in the background section.

The bottom of the first support base is rotatably connected to a second support base via a pivot. A limiting moving frame is fixedly connected to the upper surface of both the first and second support bases. A servo motor is fixedly connected to the outer wall of the limiting moving frame. A one-way screw is fixedly connected to the output end of the servo motor. A limiting moving block is threaded onto the surface of the one-way screw. A support rod is hinged to the top of the limiting moving block. The top of the support rod is hinged to the first and second support templates. Repair and leveling plates are fixedly connected to the inner walls of both the first and second support templates. Ground-piercing cones are threaded onto the outer side of the limiting moving frame on the upper surface of both the first and second support bases.

[0008] Preferably, auxiliary moving frames are fixedly connected to both the left and right sides of the limiting moving frame, and auxiliary limiting slide rods are fixedly connected to the inner sidewalls of the auxiliary moving frames. An auxiliary moving block is sleeved on the surface of the auxiliary limiting slide rod, and an auxiliary support rod is hinged to the top of the auxiliary moving block. The top end of the auxiliary support rod is hinged to the first support template and the second support template.

[0009] Preferably, reflective warning tapes are fixedly connected to the outer top ends of both the first support template and the second support template.

[0010] Preferably, there are two servo motors, which are started synchronously by a PLC linkage controller, and the two servo motors are IP67 waterproof servo motors.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a support template for repairing damaged concrete crash barriers, which has the following beneficial effects:

During use, personnel use a PLC linkage controller to simultaneously start two servo motors, driving the one-way screw to rotate left and right. This causes the limiting moving block to drive the threaded limiter of the support rod, which moves left and right according to the required support angle for repairing the damaged concrete crash barrier, thus moving the first and second support templates. The rotation adjustment repairs the support angle, and then the limiting screw is sequentially threaded to the first connecting plate, the second connecting plate, and the fixing nut for locking, until the surface of the repair flat plate and the U-shaped waterstop are attached to the damaged surface of the concrete crash barrier for repair and support. This serves to repair and support damaged areas of concrete crash barriers of different thicknesses. The reflective warning tape serves to reflect light to warn passing personnel and vehicles to avoid the damaged areas of the concrete crash barrier during nighttime repairs. The ground cones serve to position and reinforce the damaged areas of the concrete crash barrier during the repair and support process. Attached Figure Description
