Description

Technical Field

[0001] The utility model relates to a demoulding core device for the production of concrete guardrails, belonging to the field of auxiliary equipment for the production of concrete guardrails. Background Art

[0002] Guardrails are an important facility in road engineering. In some special places, such as steep mountain roads, bridges, etc., in order to ensure the stability of guardrail installation, it is usually necessary to install the guardrail on a step. Therefore, when curing the concrete guardrail, positioning holes need to be formed at the bottom of the guardrail, which requires embedding a mould core during concrete pouring.

[0003] In the prior art, after the concrete is poured, the embedded mould core is usually pulled out manually. On the one hand, it wastes manpower; on the other hand, since the operator's hand is prone to shaking, when manually pulling out the mould core, the formed positioning hole is likely to be deformed, thus reducing the forming quality of the positioning hole. Summary of the Utility Model

[0004] According to the deficiencies in the above prior art, the technical problem to be solved by the utility model is: to provide a demoulding core device for the production of concrete guardrails that can save manpower and improve the forming quality of positioning holes.

[0005] The demoulding core device for the production of concrete guardrails described in the utility model includes a bracket. A moving frame is connected to the bracket through a first linear guiding component. A displacement driving component for driving the displacement of the moving frame is connected to the bracket. One end of the moving frame extends out of the bracket and is provided with a positioning frame. A demoulding frame is connected to the moving frame through a second linear guiding component. A demoulding driving component for driving the displacement of the demoulding frame is connected to the moving frame. One end of the demoulding frame close to the positioning frame is fixedly connected with a mounting sleeve. A rotating shaft is rotatably connected in the mounting sleeve. A clamping sleeve is arranged on the rotating shaft. Two L-shaped clamping openings that are centrosymmetric are arranged on the clamping sleeve. The rotating shaft is connected with a rotation driving component.

[0006] Further, the displacement driving component includes a first ear plate fixedly connected to the bracket and a second ear plate fixedly connected to the moving frame. A displacement cylinder is connected between the first ear plate and the second ear plate.

[0007] Further, the demoulding driving component includes a third ear plate fixedly connected to the moving frame and a fourth ear plate fixedly connected to the demoulding frame. A demoulding oil cylinder is connected between the third ear plate and the fourth ear plate.

[0008] Further, the rotation driving component includes a support plate fixedly connected to the side wall of the demoulding frame and a swing plate fixedly connected to the rotating shaft. An unlocking cylinder is hinged between the support plate and the swing plate.

[0009] Further, the second linear guiding component includes a guide sleeve disposed on the moving frame and a guide rod disposed on the mold stripping frame, and the guide rod is slidably connected to the guide sleeve.

[0010] Further, the first linear guiding component includes a linear guide rail disposed on the longitudinal beam of the bracket and a guide wheel rotatably disposed on the guide sleeve, and the guide wheel rolls on the linear guide rail.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] For the mold core device for stripping of concrete guardrail of the present utility model, the moving frame and the mold stripping frame are driven to move by the displacement driving component, so that the clamping sleeve can be stuck on the locking pin of the mold core. By driving the clamping sleeve to rotate through the rotation driving component, unlocking of the mold core can be realized. By driving the mold stripping frame to move through the mold stripping driving component, the mold core can be vertically pulled out from the concrete guardrail, thus eliminating the need for manual mold stripping by workers, saving manpower and improving the forming quality of the positioning holes.
