Description

Technical Field

[0001] This utility model relates to the field of elevator shaft protection technology, and in particular to a working face elevator shaft protection device. Background Technology

[0002] Elevator shafts are among the most accident-prone areas during building construction, especially during the structural construction phase. If the elevator shaft openings are not properly protected, falls from heights are highly likely. Therefore, elevator shafts need to be protected.

[0003] For example, a reusable elevator shaft horizontal protection device for working surfaces, disclosed in CN222066232U, includes a support frame, an elevator shaft located below the support frame, a protective net fixedly connected to the support frame, and connecting plates fixedly connected to the bottom of the support frame. The beneficial effect of this utility model is that the support frame is welded from 1.2cm round steel, and the protective net is welded and fixed to the support frame from 0.8cm round steel. By placing the device on the elevator shaft and rotating the handle to drive the threaded rod, the bearing seat and pressure plate can be moved. With the cooperation of multiple fixing mechanisms below the support frame, the device can be fixed on the elevator shaft, preventing construction workers from falling into the elevator shaft. This device is highly practical, and its principle is simple and easy to understand. It provides protection for the horizontal opening of the elevator shaft, ensuring the safety of construction personnel. However, because the support frame of this elevator shaft horizontal protection device is welded from round steel, the overall structure is fixed, resulting in a large volume and inconvenience for transport during turnover.

[0004] Therefore, a protective device for elevator shafts in work areas has now been developed that can be folded and stored for easy turnover. Utility Model Content

[0005] In order to overcome the shortcomings of existing horizontal protection devices for elevator shafts in the work area, which have a fixed structure with a support frame made of round steel, are large in size and inconvenient to carry when moving around, this utility model provides a work area elevator shaft protection device that can be folded and stored for convenient turnover.

[0006] The technical solution is as follows: A protective device for elevator shafts in working areas includes a hook, a hanging plate, a rotating rod, a left folding plate, a right folding plate, a left folding rod, a right folding rod, a mesh cover, a reinforcing component, and a fixing component. A hanging plate is connected to the lower side of the hook. Multiple rotating rods are rotatably connected to the lower side of the hanging plate. Multiple left folding plates and multiple right folding plates are rotatably connected to each rotating rod. Adjacent left and right folding plates on the same horizontal plane are rotatably connected. A left folding rod and a right folding rod are rotatably connected to the lower side of each rotating rod. Left and right folding rods on the same horizontal plane are rotatably connected. A mesh cover connects the rotating rods. Both the left and right folding rods are connected to the mesh cover. Both the left and right folding plates are also connected to the mesh cover. A reinforcing component to enhance stability is provided between the left and right folding rods. A fixing component to fix the left folding rod is provided on the right folding rod.

[0007] Preferably, it also includes lighting, with lighting connected to the underside of the hanging plate.

[0008] Preferably, the reinforcing component includes a hinge fixing plate, bolts, hinge links, and a connecting seat. The left and right folding rods are each detachably connected to the hinge fixing plate by multiple bolts. The hinge fixing plate is rotatably connected to multiple hinge links, and a connecting seat is rotatably connected between two adjacent hinge links.

[0009] Preferably, each bolt is equipped with a knob.

[0010] Preferably, the fixing component includes a pin and a fixing block. Each right folding rod is connected to a fixing block, and each fixing block is engaged with a pin. Each pin engages with the adjacent left folding rod.

[0011] As a preferred option, each pin is equipped with a lever.

[0012] The beneficial effects of this utility model are as follows: By disengaging the pin from the left folding rod and then rotating the rotating rod inward to retract it, the left and right folding plates and the left and right folding rods are folded together, achieving the effect of folding and storing for convenient reuse.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] A protective device for elevator shafts at work sites, such as Figures 1-4 As shown, the assembly includes a hook 1, a hanging plate 2, a rotating rod 3, a left folding plate 4, a right folding plate 5, a left folding rod 6, a right folding rod 7, a mesh cover 8, a lighting lamp 9, reinforcing components, and fixing components. The hook 1 is connected to the hanging plate 2 at its lower side. Four rotating rods 3 are rotatably connected to the lower side of the hanging plate 2. Four left folding plates 4 and four right folding plates 5 are rotatably connected to each rotating rod 3. Adjacent left folding plates 4 and right folding plates 5 on the same horizontal plane are rotatably connected. The lower side of each moving rod 3 is rotatably connected to a left folding rod 6, and the lower side of each rotating rod 3 is rotatably connected to a right folding rod 7. The left folding rod 6 and the right folding rod 7 on the same horizontal plane are rotatably connected. A mesh cover 8 is connected between the rotating rods 3. The left folding rod 6 and the right folding rod 7 are both connected to the mesh cover 8. The left folding plate 4 and the right folding plate 5 are also connected to the mesh cover 8. A lighting lamp 9 is connected to the lower side of the hanging plate 2. A reinforcing component is provided between the left folding rod 6 and the right folding rod 7. A fixing component is provided on the right folding rod 7.

[0020] like Figures 1-4 As shown, the reinforcing assembly includes a hinge fixing plate 10, bolts 11, hinge links 12, and connecting seats 13. The hinge fixing plate 10 is detachably connected to the left folding rod 6 and the right folding rod 7 by four bolts 11. Each bolt 11 is equipped with a knob for easy rotation. Three hinge links 12 are rotatably connected to the hinge fixing plate 10. Connecting seats 13 are rotatably connected between two adjacent hinge links 12.

[0021] like Figure 2 and Figure 4 As shown, the fixing assembly includes a pin 14 and a fixing block 15. The right folding rod 7 is connected to a fixing block 15, and the fixing block 15 is snapped with a pin 14. The pin 14 is equipped with a lever for easy to move. The pin 14 is engaged with the adjacent left folding rod 6.

[0022] When using this utility model, first place the device on the elevator shaft using the hook 1 and the hanging plate 2, so that the rotating rod 3 rotates outward and opens, causing the left folding plate 4 and the right folding plate 5 to rotate into the same plane, and the left folding rod 6 and the right folding rod 7 to rotate into the same plane, so that the net cover 8 unfolds to protect the elevator shaft. When working inside the elevator shaft, the lighting lamp 9 can be turned on to illuminate the elevator shaft. The hinge fixing plate 10 is installed on the left folding rod 6 and the right folding rod 7 using the bolt 11. When the left folding rod 6 and the right folding rod 7 rotate into the same plane, the hinge connecting rod 12 is driven to rotate into the same plane, which strengthens the stability between the left folding rod 6 and the right folding rod 7. Then rotate the pin 14 to push the pin 14 into the left folding rod 6, fixing the left folding rod 6 and the right folding rod 7 into the same plane.

[0023] When the device needs to be moved, the pin 14 can be disengaged from the left folding rod 6, and the rotating rod 3 can be rotated inward to fold up the device, so that the left folding plate 4 and the right folding plate 5 are folded up, and the left folding rod 6 and the right folding rod 7 are folded up, thus enabling the device to be folded and stored for convenient reuse.

[0024] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
