Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and more specifically to a highway anti-collision guardrail inspection and repair and false seam cutting platform. Background Art

[0002] Currently, with the development of my country's national economy, bridge projects are constantly being updated, placing higher demands on project quality and safety, and on the inspection and maintenance of bridge projects. Highway guardrails are generally SA-type reinforced concrete anti-collision guardrails. After construction, guardrail slits must be promptly cut and inspected. Since slits can reduce irregular cracks in the guardrail, their quality directly affects the integrity of the guardrail. Furthermore, guardrail inspections often involve high-altitude work. Traditional false seam cutting uses a manual handheld angle grinder to cut along the ink line, resulting in a low quality assurance rate for the seam depth and width. False seam cutting on the outer side of the guardrail uses a custom-made hanger, which is less safe and inefficient. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the present invention provides a highway guardrail inspection and repair and false seam cutting platform. This platform solves the safety issues of high-altitude operations on highway guardrails and improves the false seam cutting quality of highway guardrails.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A highway anti-collision guardrail inspection and false seam cutting platform, which is hung on the highway anti-collision guardrail and includes a walking work platform, a cutting track, a cutting device and a dust reduction device. The walking work platform is set on the anti-collision guardrail, the cutting track is set at one end of the walking work platform, the cutting device is movably set on the cutting track, the dust reduction device is set on the walking work platform, and the dust reduction device is connected to the cutting device.

[0006] The walking work platform includes a platform frame, which is mounted on the anti-collision guardrail with a concave structure. A waist frame is provided on the side of the platform frame close to the road surface, and contact walking wheels are provided on the inner side and waist frame of the platform frame.

[0007] The top and both sides of the inner side of the platform frame are provided with contact running wheels.

[0008] A protective net is provided on both side surfaces of the platform frame and the outer side surface away from the road surface. The protective net is a wire mesh with a grid spacing of 5 cm.

[0009] The top of the platform frame and the side close to the road surface are open structures, and a climbing rod is provided on the inner side of the platform frame.

[0010] The cutting track includes a positioning and fixing steel plate and a precision slide rail. The positioning and fixing steel plate is arranged along one end of the platform frame, and the precision slide rail is fixed to the positioning and fixing steel plate by bolts.

[0011] The cutting equipment includes a track slider, a rocker base, a rocker and a cutter fixed base. The track slider is slidably set on the precision slide rail. Four sets of conical pulleys are set on the track slider. The track slider is slidably set on the precision slide rail through the conical pulleys. The rocker base is fixedly set on the track slider. The two ends of the rocker are respectively connected to the rocker base and the cutter fixed base through bearings. A handheld angle grinder is set on the cutter fixed base.

[0012] The rocker adopts a Z-shaped rod.

[0013] The dust reduction equipment includes a water tank, a water pump, a soft water pipe and a cooling and dust-proof nozzle. The water tank and the water pump are arranged on the road surface. The water pump is connected to the water tank. The two ends of the soft water pipe are respectively connected to the water pump and the cooling and dust-proof nozzle. The cooling and dust-proof nozzle is arranged on the fixed base of the cutting machine.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The platform frame provides the device's construction platform framework, which slides over the guardrail to facilitate construction operations. The contact wheels facilitate the mobile working platform's movement over the guardrail. The protective net enhances the platform's safety, and the ladder rails ensure easy access for construction workers. The cutting equipment slides on precision rails, enabling seamless access to the guardrail. The rocker rotates 360 degrees, enabling variable-amplitude cutting to accommodate irregular linear cuts. The dust suppression device simultaneously reduces dust during cutting, ensuring environmentally friendly construction. This device addresses the safety concerns of high-altitude operations on highway guardrails while improving the quality of false seam cutting. It's easy to operate and saves labor.
