Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a demoulding device for a precast concrete cover plate. Background Art

[0002] In recent years, with the country's massive investment in infrastructure, a new round of high-speed railway construction is being launched in China. At present, a large number of covers are used in the construction of high-speed railways. Therefore, the intrinsic quality and external appearance quality of concrete covers directly or indirectly affect the quality of our high-speed railways. In the construction of traditional precast concrete covers, one side of the mold is usually manually lifted to make the other side hit the ground, and a thrust is applied to flip the mold over to hit the precast concrete cover for demoulding. The demoulding process is time-consuming and laborious. In addition, when the mold falls under its own weight during the mold flipping process, the precast concrete cover itself is heavy and is easily damaged after falling and hitting the ground, resulting in the precast concrete cover often missing edges and corners, which not only affects the intrinsic quality of the precast concrete cover but also affects the appearance quality, which not only reduces the service life of the cover but also affects the overall appearance. Summary of the invention

DETAILED DESCRIPTION

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] refer to Figure 1 to Figure 2 As shown, a precast concrete cover demoulding device comprises:

[0023] A demoulding assembly, wherein the demoulding assembly is used to engage with the edge of the external mold, and after engagement, when the demoulding assembly is driven by an external force to flip the external mold to one side for demoulding, the external mold is prevented from being separated from the demoulding assembly. The demoulding assembly comprises a frame 21, a hollow portion 22 provided on the frame 21, and a template slot 23 provided on one end surface of the frame 21 for engaging with the edge of the external mold 11. The hollow portion 22 is used to facilitate the removal of the precast concrete cover plate 12 in the external mold 11 when the demoulding assembly drives the external mold 11 to flip to one side;

[0024] A movable arc rail, the number of which is at least two, which is arranged on the demoulding assembly, and is used to reduce resistance when the demoulding assembly is driven by an external force to flip the external mold to one side for demoulding, and the movable arc rail includes a movable arc rail body 31 and a limit rod 32 arranged on one side of the movable arc rail body 31;

[0025] A flip handrail 41, which is rotatably mounted on the demoulding assembly via a movable bolt 42, and is used for workers to hold so that the workers can push the demoulding assembly after the demoulding assembly is engaged with the edge of the external mold, so that the demoulding assembly drives the external mold to flip to one side for demoulding;

[0026] The impact reduction assembly includes a buffer foot assembly and a deceleration assembly. The buffer foot assembly is arranged on the demoulding assembly and is located at the end surface away from the external mold. The buffer foot assembly is used to contact the ground first to cushion the demoulding assembly when the demoulding assembly drives the external mold to flip to one side for demoulding. The deceleration assembly is arranged between the demoulding assembly and the flipping handrail. The deceleration assembly is used to decelerate the falling speed of the external mold when the demoulding assembly drives the external mold to flip to one side and the external mold falls due to its own weight.

[0027] The deceleration assembly includes a spring deceleration member disposed between the frame 21 and the flip armrest 41, two legs 51 disposed on the frame 21 and respectively located on both sides of the frame 21, and a limit stopper 52 extending outwardly from each leg 51, wherein the limit stopper 52 is used to limit the position of the demoulding assembly by abutting against the flip armrest when the spring deceleration member drives the demoulding assembly to reset;

[0028] The spring decelerator comprises a decelerator plate 53 and a tension spring 54. The decelerator plate 53 is arranged on the frame 21. One end of the tension spring 54 is rotatably connected to the decelerator plate 53 and the other end is rotatably connected to the flip armrest 41. There are two spring decelerators.

[0029] The buffer foot assembly includes two buffer feet, each of the two legs 51 is provided with a buffer foot, and the buffer foot includes a connecting plate 61 arranged on the leg 51, a compression spring 62 arranged on the connecting plate 61, and a silicone pad 63 arranged on the compression spring 62.

[0030] When the utility model is in use, the worker moves from one side of the external mold along the edge to the other side through the template slot 23, completes the engagement with the edge of the external mold and fixes the frame 21 on the external mold, and the worker pushes the frame 21 by holding the flip handrail 41 to make the movable arc rail body 31 hit the ground, and then continues to apply thrust to the frame 21 to drive the external mold to flip to one side along the movable arc rail body 31 and fall to the ground, so as to realize the flipping of the external mold. At this time, the precast concrete cover plate falls from the hollow part 22 on the frame 21 to complete demoulding. After demoulding, the worker pulls back the external mold along the movable arc rail body 31 through the flip handrail 41 to flip and reset it. In subsequent use, repeating the above step 1 can continuously complete the demoulding of the precast concrete cover plate.

[0031] When the demoulding assembly drives the external mold to flip to one side and the external mold falls due to its own weight, the tension spring 54 provides a certain pulling force to the falling frame 21, so as to reduce the speed of the external mold falling. And when the demoulding assembly drives the external mold to flip and contact the ground, the falling demoulding assembly is buffered by the buffer foot before contacting the ground. The utility model reduces the frame during the flipping and demoulding process by setting a shock-reducing assembly, and buffers when the frame contacts the ground, reducing the damage caused by the precast concrete cover plate hitting the ground during demoulding, ensuring the internal quality and appearance quality of the precast concrete cover plate, and improving the service life and overall aesthetics of the precast concrete cover plate.
