Description

Technical Field

[0001] This utility model belongs to the field of opening protection technology, and in particular relates to a horizontal opening protection device. Background Technology

[0002] During construction, numerous horizontal openings, such as reserved openings and equipment hoisting openings, are created on construction sites. Due to a lack of safety protection or inadequate safety measures, accidents are easily caused. Traditional methods of protecting horizontal openings typically involve placing protective covers directly over the openings. However, these covers are poorly secured, easily moved, and prone to falling. Furthermore, the multiple hooks used for hoisting in traditional covers are usually located at the top and around the perimeter of the cover, above the ground, posing a tripping hazard to workers. Therefore, it is necessary to design a horizontal opening protection device to address these technical problems. Utility Model Content

[0003] The main objective of this invention is to propose a horizontal opening protection device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A horizontal opening protection device includes a cover plate with a recessed groove in the center. A hook is fixed in the groove. Four sets of telescopic components are fixed around the bottom of the cover plate. Each telescopic component includes a fixed plate, which is fixed to the bottom of the cover plate by several rods. The fixed plate is hollow and has a movable plate embedded inside. The fixed plate and the movable plate have several pairs of through holes and are connected by bolts to adjust the telescopic length of the movable plate.

[0006] Preferably, a top plate is fixed to one end of the outer side of the movable plate.

[0007] Preferably, the four sets of telescopic components are arranged circumferentially at 90-degree intervals.

[0008] Preferably, the groove is provided with a drainage hole.

[0009] Preferably, the upper surface of the cover plate is provided with a warning sign, which is a reflective coating or raised texture.

[0010] Preferably, the lifting rod is made of angle steel.

[0011] Preferably, the fixed plate is a square tube and the movable plate is a square steel.

[0012] This utility model provides a horizontal opening protection device, which has the following beneficial effects:

[0013] 1. When using this device, the cover plate is hoisted and placed on the horizontal opening, while the four telescopic components are located inside the horizontal opening. With the support and limitation of the four moving plates on the inner wall of the horizontal opening, the cover plate will not move easily, thereby avoiding a falling accident.

[0014] 2. The fixed plate and the movable plate of this device are provided with several pairs of through holes and connected by bolts, which can adjust the extension length of the movable plate, so as to be suitable for horizontal openings of different sizes. In addition, the cover plate of this device has a groove in the middle, and the hook is fixed in the groove, so that the workers are not easily tripped when passing through, thus improving safety.

[0023] Example

[0024] Reference Figure 1-2 A horizontal opening protection device includes a cover plate 1, with a recessed groove 101 in the center of the cover plate 1. A hook 2 is fixed in the groove 101. Four sets of telescopic components 3 are fixed around the bottom of the cover plate 1. Each telescopic component 3 includes a fixed plate 31. The fixed plate 31 is fixed to the bottom of the cover plate 1 by several hanging rods 32. The fixed plate 31 has a hollow structure and a movable plate 33 is embedded inside. The fixed plate 31 and the movable plate 33 are provided with several through holes and connected by bolts 34, which can adjust the telescopic length of the movable plate 33.

[0025] In this embodiment, the cover plate 1 is made of high-quality patterned steel plate to ensure that the cover plate 1 has sufficient load-bearing capacity. Taking the dimensions of the cover plate 1 (length × width × thickness) as an example (1200mm × 1000mm × 8mm), it can adapt to horizontal openings of various sizes with a short side length of less than 1000mm. The adjustment range of the telescopic length of the movable plate 33 is 0-500mm.

[0026] When using this device, first adjust the telescopic length of the movable plate 33 in the four sets of telescopic components 3 according to the size of the horizontal opening 100. That is, select appropriate through holes on the fixed plate 31 and the movable plate 33, and fix them with bolts 34. Of course, the through holes can also be long strips, so that the bolts 34 can slide in the through holes to achieve stepless adjustment. Then, the cover plate 1 is hoisted and placed on the horizontal opening 100 by the hook 2. The four telescopic components 3 are located inside the horizontal opening 100. With the support and limit of the four movable plates 33 on the inner wall of the horizontal opening 100, the cover plate 1 will not move easily, thereby avoiding a falling accident.

[0027] The device has several through holes on the fixed plate 31 and the movable plate 33, which are connected by bolts 34. The telescopic length of the movable plate 33 can be adjusted so that it can be used for horizontal openings of different sizes. The cover plate 1 of the device has a recessed groove 101 in the middle, and the hook 2 is fixed in the groove 101. This makes it less likely for workers to trip when passing through, thus improving safety.

[0028] In one specific implementation, a top plate 35 is fixed to one end of the outer side of the movable plate 33, providing a larger support area for the inner wall of the horizontal opening and a better support and limiting effect.

[0029] In one specific implementation, the four sets of telescopic components 3 are arranged circumferentially at 90-degree intervals.

[0030] In one specific implementation, the groove 101 is provided with a drainage hole for draining accumulated water.

[0031] In one specific implementation, the upper surface of the cover plate 1 is provided with a warning sign, which is a reflective coating or raised texture, to remind construction personnel to pay attention to the safety of the opening.

[0032] In one specific implementation, the boom 32 is an angle steel.

[0033] In one specific implementation, the fixed plate 31 is a square tube and the movable plate 33 is square steel. The materials used in this device are all commonly used materials on construction sites and are easy to obtain.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
