[0026] The embodiment of the utility model provides a concrete demoulding device for road and bridge construction.

[0027] See also Figure 1 , including a demoulding operation box 1, a flat conveyor belt 10 is fixedly installed inside the demoulding operation box 1, and a controller 11 is fixedly installed on the outer surface of the demoulding operation box 1. The flat conveyor belt 10 and the controller 11 are both existing technologies and will not be described in detail in this application. The flat conveyor belt 10 can drive the setting mold 6 to move inside the demoulding operation box 1, thereby realizing the automatic demoulding operation of concrete, reducing the demand for manpower, and reducing the cost of concrete demoulding. The controller 11 can control the operation of various components of the device.

[0028] See also Figure 1 and Figure 2 The inner top wall of the demoulding operation box 1 is fixedly connected with an electric push rod 2. The electric push rod 2 is a prior art and will not be described in detail in this application. The electric push rod 2 can automatically rise and fall inside the demoulding operation box 1 according to the parameters set on the solidification mold 6. The lifting of the electric push rod 2 can drive the positioning mechanism 3 to rise and fall, thereby adjusting the height of the positioning mechanism 3, so that the device can automatically perform the demoulding operation.

[0029] A setting mold 6 is provided on the top surface of the flat conveyor belt 10. A receiving plate 7 corresponding to the setting mold 6 is fixedly connected to the top surface of the flat conveyor belt 10. The setting mold 6 can hold concrete and allow it to set into blocks after standing. The height of the receiving plate 7 is consistent with the wall thickness of the setting mold 6. When the concrete block detaches from the setting mold 6, the receiving plate 7 can just hold the concrete block to prevent the concrete block from colliding with other objects and causing damage to the device or the concrete block.

[0030] See also Figure 4 The inner wall of the solidification mold 6 is provided with a slot 8, and the inner wall of the slot 8 is hinged with a hinged baffle 9 through a pin. Through the arrangement of the slot 8 and the hinged baffle 9, when the solidification mold 6 is opened upward, the hinged baffle 9 will automatically close with the slot 8. At this time, the concrete liquid is poured into the solidification mold 6. The hinged baffle 9 can prevent the liquid from flowing from the slot 8 to the outside of the solidification mold 6. After the concrete liquid solidifies, when the positioning mechanism 3 demoulds the concrete block, a large amount of air will flow into the interior of the solidification mold 6 through the slot 8. Under the push of air pressure, the concrete block will slowly move from the inside of the solidification mold 6 to the outside, and finally complete the demoulding operation. At this time, the hinged baffle 9 will not hinder the entry of air.

[0031] Please refer again Figure 1 and Figure 2 Two guide plates 12 are fixedly connected to the inner wall of the demolding operation box 1. Each guide plate 12 is slidably connected to the solidification mold 6. The guide plates 12 can gather the solidification mold 6 placed on the flat conveyor belt 10 to the middle of the demolding operation box 1, thereby facilitating the positioning of the positioning mechanism 3 and avoiding deviation in the position of the solidification mold 6 and affecting the demolding operation of the device.

[0032] See also Figure 1 、 Figure 2 and Figure 3 An air compressor 4 is fixedly installed on the top surface of the demoulding operation box 1, and an air duct 5 is fixedly connected to the outside of the air compressor 4. The air duct 5 is fixedly connected to the hollow tube 302. The air duct 5 is a plastic hose. The air compressor 4 is a prior art and will not be described in detail in this application. When the air compressor 4 is running, a large amount of air can be transported to the inside of the air duct 5. The air duct 5 transports the air to the setting mold 6 through the hollow tube 302, thereby using the pressure difference to push the concrete block inside the setting mold 6 to separate from the setting mold 6, reducing the damage to the mold and the concrete block during the demoulding process.

[0033] A positioning mechanism 3 is provided below the electric push rod 2. The positioning mechanism 3 includes a connecting sleeve 301. The outer surface of the connecting sleeve 301 is fixedly connected to a connecting rod 305. The connecting rod 305 is fixedly connected to the bottom end of the electric push rod 2. When the electric push rod 2 is raised or lowered inside the demolding operation box 1, the connecting sleeve 301 can be driven to rise or fall through the connecting rod 305, thereby changing the height of the connecting sleeve 301, so that the positioning mechanism 3 can adjust the air inlet position of the air guide pipe 5 according to the position of the solidification mold 6.

[0034] The interior of the connecting sleeve 301 is fixedly connected to a hollow tube 302, and one end of the hollow tube 302 is slidably connected to a positioning tube 303. The end of the positioning tube 303 has a certain inclined surface. When the electric push rod 2 descends, the positioning tube 303 will contact the condensation mold 6 and be squeezed, thereby retracting into the interior of the hollow tube 302. When the electric push rod 2 descends to a suitable position, the positioning tube 303 contacts the cavity opened in the condensation mold 6. At this time, the positioning tube 303 will rebound and reset, thereby plugging into the cavity on the condensation mold 6, thereby improving the stability of air transmission by the hollow tube 302.

[0035] The interior of the hollow tube 302 is slidably connected with a buffer ring 304, and the two ends of the buffer ring 304 are fixedly connected to the hollow tube 302 and the positioning tube 303 respectively. The buffer ring 304 is made of rubber and has good elasticity and toughness. It can provide space for the retraction of the positioning tube 303 and provide power for the rebound of the positioning tube 303. The positioning tube 303 can also improve the sealing between the positioning tubes 303 and the positioning tubes 303, thereby preventing air from flowing out through the gap between the hollow tube 302 and the positioning tube 303 and affecting the efficiency of the device demolding.

[0036] Working principle: When the staff wants to demould the concrete module that has been placed in a static state, they first place the setting mold 6 on the flat conveyor belt 10 and make the opening of the setting mold 6 face the demoulding operation box 1, and then start the device. When the setting mold 6 moves to the appropriate position inside the demoulding operation box 1, the flat conveyor belt 10 stops moving. At this time, the electric push rod 2 begins to extend downward, and the electric push rod 2 drives the hollow tube 302 to descend. When the positioning tube 303 contacts the setting mold 6, the positioning tube 303 will squeeze the buffer collar 304 and thus retract to the inside of the hollow tube 302. When the positioning tube 303 drops to contact the hollow on the setting mold 6, the buffer collar 304 pushes the positioning tube 303 to rebound, thereby clamping the positioning tube 303 with the hollow. At this time, the air compressor 4 is started, and the air compressor 4 compresses the air and transports the compressed gas to the setting mold 6 through the air guide pipe 5 and the hollow tube 302. The compressed gas can push the concrete block inside the setting mold 6 to move, thereby realizing the demoulding operation of the concrete.
