Description

Technical Field

[0001] The utility model belongs to the technical field of construction operation equipment, and in particular relates to an attached lifting scaffolding flap safety prevention device. Background Art

[0002] The attached lifting scaffolding, also known as the climbing frame, is a scaffolding that is erected at a certain height and attached to the engineering structure. It relies on its own lifting equipment and devices to climb or descend layer by layer with the engineering structure. It has the advantages of anti-overturning and anti-falling. It is mainly composed of a frame structure, attached supports, protection system, lifting system and control device.

[0003] The construction protection system is composed of a perforated steel plate protection net, a rigid walkway plate, and a steel protective flap. When the lifting scaffold is attached for lifting, the flap is generally flipped inward (away from the wall). However, if the scaffold shakes during lifting or the manual operation is not standardized, the flap may flip outward and cause an accident, which poses a serious safety risk. Utility Model Content

[0004] In order to solve the above problems, the utility model discloses an attached lifting scaffold flap safety prevention device, which utilizes a spring hook to pull the flap and the auxiliary plate together to achieve an effective opening state of the flap, thereby reducing the occurrence of safety accidents.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A safety precaution device for an attached lifting scaffold flap comprises a flap, a sub-plate, a spring hook and a lower fixing piece, wherein the flap and the sub-plate are connected via a hinge, the lower fixing piece is fixed on the surface of the sub-plate, a circular ring is provided on the lower fixing piece, one end of the spring hook is a free end and the other end is a curved hook, the free end of the spring hook is fixed on the lower side of the flap surface, and the curved hook hooks the circular ring.

[0007] As an improvement of the utility model, a U-shaped ring is fixed on the upper side of the flap surface.

[0008] As an improvement of the utility model, the distance from the free end of the spring hook to the U-shaped ring is smaller than the distance from the free end of the spring hook to the circular ring.

[0009] As an improvement of the utility model, the lower fixing member includes a bottom plate and a circular ring, the bottom plate is fixed on the surface of the auxiliary plate, and the circular ring is fixed above the bottom plate.

[0010] As an improvement of the utility model, the number of the circular rings is two, and the two circular rings and the free end of the spring hook are in a straight line.

[0011] As an improvement of the utility model, a rubber pad is provided above the back side of the flap.

[0012] The beneficial effects of the utility model are:

[0013] (1) By using a spring hook to hook the ring of the lower fixing part, the flap can be effectively reversed when the attached lifting scaffold is lifted, avoiding the risk of the flap turning outward due to shaking during lifting or improper manual operation, thereby reducing the occurrence of safety accidents.

[0014] (2) A rubber pad is installed on the upper back of the flap to solve the problem of wear and damage caused by partial closure and repeated opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] As shown in the figure, the utility model is an attached lifting scaffold flap safety precaution device, comprising a flap 1, a sub-plate 2, a spring hook 3, and a lower fixing member 4, wherein the flap 1 and the sub-plate 2 are connected by a hinge 5, the flap 1 is tilted and placed on the wall 13 side, the sub-plate 2 is connected to the scaffolding board 12, the lower fixing member 4 is fixed to the surface of the sub-plate 2, a circular ring 6 is provided on the lower fixing member 4, one end of the spring hook is a free end 7, and the other end is a curved hook 8, the free end 7 of the spring hook is fixed to the lower side of the flap 1 surface, a U-shaped ring 9 is fixed to the upper side of the flap 1 surface, the distance from the free end 7 of the spring hook to the U-shaped ring 9 is smaller than the distance from the free end 7 of the spring hook to the circular ring 6, before the attached lifting scaffold is lifted, the circular ring 6 is hooked with the curved hook 8 (the spring is stretched at this time), so that the flap 1 is away from the wall 13 side, as shown in FIG. Figure 1 As shown, the flap is effectively reversed (the tilt angle is pulled from the original 30° to 80°), avoiding the risk of the flap turning outward when shaking during lifting or improper manual operation, and reducing the occurrence of safety accidents. When the attached lifting scaffold is lifted to the right position, the hook 8 is removed from the ring 6, so that the flap 1 is tilted again and placed on the side of the wall 13, as shown in FIG. Figure 2 As shown, the hook 8 hooks the U-shaped ring 9 upwards (the spring is in a relaxed state at this time), which will not affect the workers' walking.

[0024] When the hook 8 of the utility model hooks the U-shaped ring 9 upward, the spring is not subjected to force, and its function is only to prevent the spring from swinging around; when the hook 8 hooks the ring 6 downward, there is a large pulling force, which can make the flap 1 away from the wall 13 side.

[0025] The lower fixing member of the utility model comprises a bottom plate 10 and a ring 6. Figure 4 As shown, the bottom plate 10 is welded to the surface of the auxiliary plate 2, and the circular ring 6 is fixed above the bottom plate 10; the number of the circular ring 6 can be more than one, and several circular rings 6 are in a straight line with the free end 7 of the spring hook, and the hook 8 hooks different circular rings 6, and its pulling force is also different.

[0026] The utility model is provided with a rubber pad 11 above the back side of the flap 1 to solve the problem of wear and damage caused by partial loose closing and repeated opening.

[0027] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
