Description

Technical Field

[0001] This utility model relates to the field of concrete guardrail production, and in particular to an opening and closing device for a concrete guardrail casting mold. Background Technology

[0002] Concrete guardrails are building components commonly used in traffic management, road isolation, and safety protection. They are mainly composed of cement, sand, aggregates, and other materials. They are characterized by high strength, durability, and good wind resistance, effectively resisting impacts and severe weather conditions, ensuring their service life. Concrete guardrails are widely used in highways, urban roads, bridges, and residential areas, serving to prevent traffic accidents, separate lanes, beautify the environment, and enhance safety.

[0003] Depending on the design requirements, concrete guardrails can have different appearances, including standard, wave-shaped, and patterned types, to meet the visual needs of different locations. In addition to basic safety protection functions, some guardrails also incorporate reflective markings, warning signs, and other elements to improve visibility at night or in inclement weather and enhance safety.

[0004] Precast concrete railings are produced by applying a release agent to the inner surface of the mold, placing a reinforcing cage inside, pouring concrete, and then demolding after it has solidified. However, the traditional demolding method involves manually removing the concrete railing from the mold and then using hoisting equipment to remove it. This demolding method is time-consuming, labor-intensive, and inefficient. Therefore, an opening and closing device for concrete railing casting molds is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an opening and closing device for concrete guardrail casting molds, which aims to improve the traditional demolding method, which involves manually removing the concrete guardrail from the mold and then using hoisting equipment to remove it. This demolding method is time-consuming, labor-intensive, and inefficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an opening and closing device for a concrete guardrail casting mold, comprising a bracket, two connecting rods rotatably connected to the inner side of the bracket, a mold opening component installed on the inner side of the bracket, and a dust collection component installed on the rear side of the bracket;

[0007] The mold opening assembly includes a mold and four hydraulic cylinders. The bottom of the mold is slidably connected to the inside of the bracket. A fixed shell with springs is fixedly connected to the left, right, and rear sides of the mold. Multiple springs are fixedly connected to the inner wall of the fixed shell. A locking block is fixedly connected to the outside of the springs. The four hydraulic cylinders are rotatably connected to the inside of the connecting rod and the rear side of the bracket, respectively. A rotating plate is rotatably connected to the output end of the hydraulic cylinder. A cylinder is fixedly connected to the outside of the rotating plate. A push plate is fixedly connected to the output end of the cylinder.

A collection frame is slidably connected inside the housing, and a fan is fixedly connected to the right side of the collection frame. An outer shell is fixedly connected to the rear side of the housing, and an insert rod is slidably connected inside the outer shell. A sliding plate is fixedly connected to the outside of the insert rod, and a second spring is fixedly connected to the left side of the sliding plate. A baffle is slidably connected inside the outer shell, and a limit plate is fixedly connected to the top of the outer shell.

[0010] As a further description of the above technical solution:

[0011] The bottom of the rotating plates on the left and right sides is rotatably connected to the inside of the connecting rod, and the bottom of the two rotating plates on the rear side is rotatably connected to the rear of the bracket.

[0012] As a further description of the above technical solution:

[0013] The fixed shell is externally slidably connected to the inner side of the rotating plate, and the locking block is externally rotatably connected to the inner wall of the fixed shell.

[0020] As a further description of the above technical solution:

[0021] The right side of the baffle abuts against the left end of the insert rod, and the bottom of the baffle abuts against the top of the slide plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the hydraulic cylinder drives the rotating plate to approach the mold, and at the same time the hydraulic cylinder squeezes the clamping block to compress the spring. When the rotating plate is completely in contact with the mold, the spring pushes the clamping block to pop out and block the rotating plate. The hydraulic cylinder drives the rotating plate to flip and unfold, thereby opening the left and right sides and the rear side of the mold, thus realizing demolding, saving time and effort, and reducing the fatigue of workers.

[0024] 2. In this utility model, when the high-pressure air duct blows air to remove impurities from the guardrail, the air intake is drawn in by the fan, and all the dust, sand and other debris blown up are sucked into the collection box for collection. At the same time, the spring pushes the sliding plate to insert the rod into the collection box, which avoids the debris flying around and affecting the working environment. The collection box can also be quickly removed for easy disposal of the debris collected in the collection box. Attached Figure Description

[0037] Working Principle: When using this device to open the concrete guardrail mold, the mold 2 moves between the two connecting rods 6 through the support and limiting of the bracket 1. Then, the connecting rods 6 are controlled to descend, blocking the left and right sides of the mold 2. Next, the four hydraulic cylinders 7 are controlled to work, causing the rotating plate 8 to flip and approach the mold 2. Initially, the rotating plate 8 squeezes the locking block 5 and compresses the spring 4, sliding outside the fixed shell 3. When the rotating plate 8 is completely in contact with the mold 2, the spring 4 will immediately push the locking block 5, causing the locking block 5 to pop out and block the outside of the rotating plate 8. Then, the hydraulic cylinders 7 are controlled to drive the rotating plate 8 to flip and unfold, opening the left, right, and rear side plates of the mold 2, thus opening the mold. Then, high-pressure air is used to blow air onto the surface of the guardrail to blow away impurities. At the same time, the blower 15 is controlled to work, causing the air intake 11 to generate suction, sucking away the blown impurities and collecting them in the collection frame 14 along the air pipe 12 to prevent impurities from affecting the working environment. Finally, the production is completed by transporting the guardrail away (vacuum suction cups or hoisting structures can be installed on the top). (According to existing technology), then the hydraulic cylinder 7 is used to align the rotating plate 8 and merge the side plates of the mold 2. Then, the cylinder 9 is controlled to push the push plate 10, pushing the locking block 5 into the fixed shell 3. The hydraulic cylinder 7 is controlled again to flip the rotating plate 8, causing the rotating plate 8 to separate from the mold 2. The connecting rod 6 is then controlled to lift, allowing the mold 2 to be moved away so that the next mold can be opened. After a period of use, the impurities inside the collection frame 14 need to be cleaned. By pulling the insertion rod 17, the sliding plate 18 is driven to compress the spring 19, so that the insertion rod 17... The tube is retracted into the housing 16 and detached from the collection frame 14. At the same time, the baffle 20 automatically falls into the housing 16, blocking the outlet of the insertion rod 17. Then, the collection frame 14 is pulled out from the housing 13 and the impurities inside are removed. It is then reinserted into the housing 13. Next, under the limit of the limiting plate 21, the baffle 20 is pulled. At this time, the spring 2 19 will immediately push the slide plate 18 to reset, driving the insertion rod 17 to insert into the collection frame 14, thus fixing the collection frame 14. It can then be used again. The operation is convenient and labor-saving.
