Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a safety protection net assembly for a construction site. Background Technique

[0002] During construction at a building construction site, holes are often reserved or foundation pits are excavated due to construction requirements. To avoid potential safety hazards left at the construction site, the surrounding of the construction usually needs to be enclosed with a safety protection net.

[0003] In the existing safety protection net technology, although it can play a role in isolation and protection to avoid the hidden danger of personnel accidentally entering and getting injured, there are still deficiencies in its actual use. For example, the device lacks a disassembly and assembly mechanism. As a result, after the net panel assembly is corroded by external influences or accidentally collides and breaks, it is inconvenient to disassemble from the frame, leading to the problem that the entire device is scrapped, causing a large loss of equipment. To avoid such problems, a safety protection net assembly for a construction site is proposed to solve the existing problems. Summary of the Utility Model

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A safety protection net assembly for a construction site includes a frame and a net panel. The net panel is slidably arranged inside the frame. A pull plate is slidably arranged at the rear side of the frame. On both sides of the front side of the pull plate, limit pins are fixedly connected and used in cooperation with the net panel. One end of the limit pin slidably extends into the frame. Through grooves used in cooperation with the limit pins are respectively opened on both sides of the rear side of the frame. Card slots used in cooperation with the limit pins are respectively opened on both sides of the front side of the inner cavity of the frame. A lifting and supporting mechanism is arranged between the pull plate and the frame.

[0006] Preferably, the lifting and supporting mechanism includes sliding grooves. There are two sliding grooves, and the two sliding grooves are respectively opened on both sides of the rear side of the frame. A slider used in cooperation with the pull plate is slidably connected inside the sliding groove. A connecting rod bracket is fixedly connected to the rear side of the slider, and one end of the connecting rod bracket extends into the frame. A support plate used in cooperation with the net panel is fixedly connected to the surfaces of the two connecting rod brackets inside the frame. On both sides of the rear side of the frame, a sleeve used in cooperation with the limit pin is fixedly connected.

[0007] Preferably, sleeves are fixedly connected to both sides of the front side of the pulling plate. A telescopic rod is slidably connected inside the sleeve, and the front side of the telescopic rod is fixedly connected to the rear side of the slider. A return spring is fixedly connected between the adjacent telescopic rod and the sleeve.

[0008] Preferably, driving long grooves are provided on both sides of the rear side of the frame and are used in cooperation with the connecting rod brackets.

[0009] Preferably, a warning sticker is provided on the front side of the frame.

[0010] Beneficial effects

[0011] The utility model provides a safety protection net assembly for a construction site. Compared with the prior art, the following beneficial effects are achieved: by sliding the mesh panel inside the frame and arranging a pulling plate and a limit pin between the mesh panel and the frame, the mesh panel and the frame are easy to disassemble and assemble, avoiding the problem that the device is easily scrapped as a whole after the mesh panel is damaged. Secondly, a lifting and supporting mechanism is arranged between the pulling plate and the frame, so that when the mesh panel and the frame are disengaged from the limit fit through the pulling plate and the limit pin, the mesh panel can also be lifted and temporarily supported by the pulling plate and the limit pin, achieving the effect of facilitating the taking of the mesh panel.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figures 1-8 , the present invention provides a technical solution: a safety protection net assembly at the construction site, including a border 1 and a mesh panel 2. The mesh panel 2 is slidably arranged inside the border 1, and a warning sticker 12 is arranged on the front side of the border 1.

[0023] Furthermore, for the convenience of disassembling and assembling the mesh panel 2 and the border 1, a pull plate 3 is slidably arranged on the rear side of the border 1. Both sides of the front side of the pull plate 3 are fixedly connected with limit pins 4 that are used in cooperation with the mesh panel 2, and one end of the limit pin 4 slidably extends into the inside of the border 1. Through slots 5 that are used in cooperation with the limit pins 4 are respectively opened on both sides of the rear side of the border 1, and card slots 6 that are used in cooperation with the limit pins 4 are respectively opened on both sides of the front side of the inner cavity of the border 1. A lifting and supporting mechanism 7 is arranged between the pull plate 3 and the border 1. The lifting and supporting mechanism 7 includes chutes 71. There are two chutes 71, and the two chutes 71 are respectively opened on both sides of the rear side of the border 1. Sliders 72 that are used in cooperation with the pull plate 3 are slidably connected inside the chutes 71. Both sides of the front side of the pull plate 3 are fixedly connected with sleeves 8. Telescopic rods 9 are slidably connected inside the sleeves 8, and the front sides of the telescopic rods 9 are fixedly connected with the rear sides of the sliders 72. A return spring 10 is fixedly connected between adjacent telescopic rods 9 and sleeves 8;

[0024] Furthermore, for the convenience of supporting the top of the mesh panel 2, the rear side of the slider 72 is fixedly connected with a connecting rod bracket 73, and one end of the connecting rod bracket 73 extends into the inside of the border 1. A support plate 74 that is used in cooperation with the mesh panel 2 is jointly fixedly connected on the surfaces of the two connecting rod brackets 73 and inside the border 1. Bushings 75 that are used in cooperation with the limit pins 4 are respectively fixedly connected on both sides of the rear side of the border 1, and driving long slots 11 that are used in cooperation with the connecting rod brackets 73 are respectively opened on both sides of the rear side of the border 1.

[0025] When it is necessary to disassemble and replace the damaged mesh panel 2, the operator first pulls the pull plate 3 backward, causing the pull plate 3 to drag the limit pin 4 to the rear side of the border 1, causing the limit pin 4 to be disengaged from the limit cooperation with the mesh panel 2. Then, the pull plate 3 and the limit pin 4 are dragged upward until the limit pin 4 rises to the position of the bushing 75. Then, the limit pin 4 is inserted into the inside of the bushing 75 for temporary limit fixation;

[0026] While the pull plate 3 drags the limit pin 4 to rise, the pull plate 3 simultaneously drives the slider 72 to rise by means of the sleeve 8, the telescopic rod 9 and the return spring 10. The slider 72 drives the connecting rod bracket 73 and the support plate 74 to rise. The rise of the support plate 74 lifts the mesh panel 2 from the inner top of the frame 1.
