[0002] With the gradual popularization of new formwork systems such as combined aluminum alloy formwork and aluminum frame wood formwork, its advantages have gradually been recognized by the market. The formwork is light in weight, high in strength, can be dismantled early, and has good comprehensive economic benefits. In residential construction, one layer of formwork and three layers of support are generally configured. According to the construction progress, the operator transports the material upward layer by layer through the material transfer port. The material transfer port needs to be used continuously during the construction of these three layers and cannot be closed. It is necessary to wait until all the support parts are transported to the working layer before the edge of the material transfer port can be blocked, and finally concrete is used for unified blocking. By observing the traditional practice, during the construction of these three layers, the material transfer port is generally temporarily covered with wooden boards, which cannot be effectively fixed and are easy to lose. It is often necessary to process the cover plate multiple times, which is a waste of materials and has poor protection effect.

[0025] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The lifting protection device for automatically opening the aluminum mold material transfer port according to the embodiment of the present invention is as follows: Figure 1-3 As shown, it includes a support frame 3 detachably installed at the material transfer port 1 and a cover plate 5 hinged on the support frame 3, an elastic hinge 4 for automatically popping open the cover plate 5 is fixed on the support frame 3, an elastic plug rod 7 is movably installed along the lower surface of the cover plate 5 through a connecting piece, a slot 15 component is provided on the support frame 3 for the second end of the elastic plug rod 7 to be inserted when it pops out, and a hook 8 is connected to the elastic plug rod 7.

[0028] Based on the above embodiment, the connecting member can be a connecting tube 10 whose outer tube wall is fixed to the lower surface of the cover plate 5, and the elastic insertion rod 7 is inserted and movably connected in the connecting tube 10, such as Figure 3 As shown, the first end of the elastic rod 7 is provided with an elastic member 6, and the second end of the elastic rod 7 passes through the end of the connecting tube 10. In one embodiment, one end of the connecting tube 10 can be closed, and the two ends of the elastic member 6 are respectively welded to the closed end of the connecting tube 10 and the first end of the elastic rod 7. An opening is provided in the middle of the connecting tube 10, and the part of the elastic rod 7 located in the opening is connected to the hook 8.

[0029] Based on the above embodiment, the elastic hinge 4 can be a stainless steel spring hinge, also known as a spring hinge, through which the cover plate 5 can be automatically opened without any other external force, thereby achieving the effect of automatically opening the material transfer port 1. Fig. 9 , shows a schematic structural diagram of a stainless steel spring hinge in an embodiment.

[0030] In actual application, when the cover 5 is closed and locked with the support frame 3, a heavy object is hung on the hook 8, and the heavy object pulls the elastic rod 7 to move downward and deform. The length of the elastic rod 7 at the opening in the middle of the connecting tube 10 increases, thereby pulling the elastic component 6 to deform, wherein the elastic component 6 can be a spring or a tension spring. At this time, the first end of the elastic rod 7 pulls the spring to stretch and deform, and the second end of the elastic rod 7 moves away from the slot 15 component due to the deformation and contraction of the elastic rod 7, thereby unlocking the cover 5. At this time, under the action of the elastic hinge 4, the cover 5 automatically opens and drives the heavy object hanging on the hook 8 to move upward and be lifted; when the heavy object is removed, the elastic rod 7 returns to its original state under the action of its own elasticity and returns to its original position under the action of the elastic component 6. Among them, it should be explained that the elasticity of the elastic component 6 is average. When a heavy object is hung on the hook 8, the middle of the elastic rod 7 is pulled down by the gravity of the heavy object, resulting in vertical deformation, and the elastic rod 7 placed in the connecting tube 10 contracts in the horizontal direction. Since the elastic component 6 is pulled on the left side, the horizontal contraction of the left side of the elastic rod 7 is smaller than that of the right side. Since the elasticity of the elastic component 6 is average, it can not only ensure the balance of the suspended heavy object basically located in the middle of the elastic rod 7, but also ensure that the elastic rod 7 can be restored to its original position.

[0031] Furthermore, the slot 15 component includes a slot 15 arranged on the support frame 3, for the second end of the elastic rod 7 to be inserted and the upper end is open. The upper end opening of the slot 15 is covered with a spring sheet 11. When the heavy object is removed, the elastic rod 7 returns to its original position under the action of the elastic component 6, so that the second end of the elastic rod 7 pops out of the connecting tube 10 and can be connected to the slot 15. The first side of the spring sheet 11 is fixedly connected to the support frame 3, and the second side opposite to the first side of the spring sheet 11 is deformed as the second end of the elastic rod 7 is pressed into the slot 15, and the deformation is restored after the second end of the elastic rod 7 is completely pressed into the slot 15. The restored spring sheet 11 limits the second end of the elastic rod 7 in the slot 15, so that the cover plate 5 is locked on the support frame 3 to close the material transfer port 1, and it is also convenient for the next heavy object lifting.

[0032] An implementation scheme based on the above embodiment is as follows: Figure 4 , 5 As shown, the number of the spring pieces 11 is two, and the first sides of the two spring pieces 11 are respectively fixed on the two side walls opposite to the upper opening of the slot 15, and the second sides of the two spring pieces 11 are mutually overlapped, and the second end of the elastic rod 7 enters the slot 15 from the side where the two spring pieces 11 are mutually overlapped. In practical applications, the two spring pieces 11 can be two arc-shaped spring pieces 11 arranged opposite to each other, so that it is more convenient to press the elastic rod 7 into the slot 15, and at the same time, the locking effect of the elastic rod 7 is better, and the elastic rod 7 is not easy to pop out by itself. Figure 4 FIG. 1 is a schematic diagram of the structure before the elastic rod 7 is inserted into the slot 15. Figure 5 The figure is a schematic diagram of the structure after the elastic rod 7 is inserted into the slot 15 , and two spring pieces 11 are sealed at the upper end of the elastic rod 7 to lock the elastic rod 7 , thereby preventing the cover plate 5 from automatically popping open under the action of the elastic hinge 4 .

[0033] More preferably, the portion of the elastic rod 7 at the opening is arc-shaped, protruding downward at the opening and connected to the hook 8. The arc-shaped protruding portion facilitates the connection with the hook 8 and is more conducive to the deformation of the elastic rod 7 when hanging heavy objects.

[0034] like Figure 6 As shown, the lower end surfaces of the opposite side edges of the support frame 3 are respectively connected to the clamping devices 2 through fasteners, and the clamping device 2 includes a vertical rod 204, and the upper end of the vertical rod 204 is fixedly connected to the horizontal plate 201, and a limiting plate 202 is also provided on the vertical rod 204. The horizontal plate 201 and the limiting plate 202 form a jaw for clamping on the edge of the material transfer port 1. During installation, the clamping device 2 can be installed on the material transfer port 1 first, and then the clamping device 2 is connected to the support frame 3 through fasteners, so that the support frame 3 and the cover plate 5 and other structures are installed at the material transfer port 1.

[0035] Better, such as Figure 8 As shown, one end of the limit plate 202 is fixedly connected to a circular ring 14, which is sleeved and slidably connected to the vertical rod 204. A hole is opened on the circular ring 14 and a bolt is threaded in the hole. The tail end of the bolt passes through the circular ring 14 and rests on the vertical rod 204. The limit plate 202 can be adjustably installed on the vertical rod 204 through the bolt, circular ring and other structures, so as to facilitate the installation of plates of different thicknesses matching the material transfer port 1.

[0036] Preferably, the vertical rod 204 is provided with an anti-drop component 203 located below the limiting plate 202, which can prevent the limiting plate 202 from detaching from the vertical rod 204 and falling off. The anti-drop component 203 can be a mounting rod installed at the bottom end of the vertical rod 204.

[0037] Better, such as Figure 7 As shown, a strip-shaped empty groove 13 is provided in the middle of the transverse plate 201 along the length direction of the transverse plate 201, and the fastener is a bolt 12 which is slidably connected in the empty groove 13 and connected to the support frame 3. By providing the strip-shaped empty groove 13 on the transverse plate 201, the support frame 3 can be installed at different positions of the clamping device 2 through the fastener, so that the width of the clamping device 2 on the opposite sides can be adjusted, thereby achieving the purpose of matching the material transfer ports 1 of different sizes for use.

[0038] A handle 9 is provided on the upper surface of the cover plate 5, and the handle 9 is fixedly installed at one end of the cover plate 5 relative to the elastic hinge 4. The handle 9 is more convenient for manual operation, and the installation position of the handle 9 is at the end of the cover plate 5 relative to the elastic hinge 4, which saves more effort for closing the cover plate 5 when applying force.

[0039] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.
