Description

Technical Field

[0001] This application relates to the technical field of guardrail maintenance devices, and in particular to a cast-in-place concrete guardrail maintenance device. Background Technology

[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden and gain strength normally or at an accelerated pace. The gradual hardening and strength gain of concrete is a result of cement hydration, which requires specific temperature and humidity conditions.

[0003] The published patent application CN220741611U discloses a concrete guardrail curing device, relating to the technical field of guardrail curing devices. It includes a main curing plate and a side curing plate rotatably connected to the main curing plate. The main curing plate is connected to a clamping mechanism for restricting the rotation of the side curing plates. The clamping mechanism includes a base plate and an abutment plate slidably connected to the base plate. The abutment plate is connected to a pushing member for pushing the abutment plate towards the base plate. In this application, concrete is placed between the main curing plate and the side curing plates. One side of the base plate abuts against the side curing plate. The pushing member slides towards the abutment plate, abutting against the abutment plate and pushing the abutment plate towards the main curing plate until the abutment plate abuts against the main curing plate. The main curing plate and the side curing plates are clamped by the abutment plate and the base plate, thereby restricting the rotation between the main curing plate and the side curing plates. This ensures that the main curing plate and the side curing plates are tightly fitted to the concrete, improving the performance of the bridge concrete crash barrier.

[0004] When the above devices are implemented, the main curing plate and the side curing plate contact the surface of the guardrail to protect it. However, the existing cast-in-place concrete guardrail curing device cannot adjust the distance between the main curing plate and the side curing plate, which means that the main curing plate and the side curing plate need to be replaced when protecting guardrails of different widths.

A moisture retention board is fixedly connected to the side of the heat preservation board away from the curing board. The moisture retention board is made of polystyrene, and the heat preservation board is made of rock wool.

[0010] By adopting the above technical solution, the insulation of the maintenance board is enhanced by the insulation board, and the moisture retention of the maintenance board is enhanced by the moisture retention board, thus improving the insulation and moisture retention of the maintenance board.

[0011] In a preferred embodiment, the maintenance mechanism includes a water tank, which is fixedly connected to a fixed plate. A water supply pipe is fixedly connected to the bottom of the water tank, and a water distribution pipe is fixedly connected to the bottom of the water supply pipe. A plurality of nozzles are fixedly connected to the surface of the water distribution pipe, and the plurality of nozzles are evenly distributed on the surface of the water distribution pipe.

[0012] By adopting the above technical solution, water is poured into the water tank, then the water in the tank is transported to the distribution pipe through the water supply pipe, and then the water is sprayed onto the surface of the guardrail by the nozzles on the surface of the distribution pipe to maintain the guardrail. This method can better maintain the guardrail.

[0013] In a preferred embodiment, the interior of the water tank is funnel-shaped.

[0014] By adopting the above technical solution, the funnel-shaped interior of the water tank can better deliver water to the inside of the water pipe.

[0015] In a preferred embodiment, a wear-resistant layer is fixedly connected to the side of the maintenance board away from the guardrail, and the wear-resistant layer is made of alumina ceramic.

[0016] By adopting the above technical solution, a wear-resistant layer is fixedly connected to the side of the maintenance board away from the guardrail, and the wear-resistant layer protects the maintenance board, which can better extend the service life of the maintenance board.

[0017] The beneficial effects of this application are:

[0018] 1. This cast-in-place concrete guardrail curing device, by setting up curing plates, a handwheel, a first threaded rod, and a second threaded rod, rotates the handwheel to drive the first and second threaded rods to rotate, which in turn drives the two curing plates to move, and the curing plates then contact the surface of the guardrail to protect it. This avoids the problem of existing cast-in-place concrete guardrail curing devices that cannot adjust the distance between the main curing plate and the side curing plates, thus improving practicality.

[0019] 2. This cast-in-place concrete guardrail curing device, by setting up an insulation board and a moisture-retaining board, enhances the heat insulation of the curing board through the insulation board and enhances the moisture retention of the curing board through the moisture-retaining board. This avoids the problem of existing cast-in-place concrete guardrail curing devices being unable to insulate and retain moisture during winter curing, thus improving practicality.

Curing plates 21 are threadedly connected to the outside of both the first threaded rod 23 and the second threaded rod 24. The curing plates 21 are slidably connected to the fixed plate 1. A groove 6 is provided on the surface of the fixed plate 1, and the groove 6 is adapted to the curing plates 21. By providing a groove 6 on the surface of the fixed plate 1 and limiting the curing plates 21, the curing plates 21 can be moved more effectively on the surface of the fixed plate 1.
