Abstract

The present invention discloses a multi-layer reinforcement protection device, including a counterweight box, in which a driving motor is arranged, and the driving motor is connected to a supporting cantilever through a gear transmission. The application adopts a multi-layer height design, which can play a buffering and insurance role for people in three times. The first layer is a dense mesh protection net, which is closer to the upper floor, and the horizontal cantilever is relatively short. When the worker steps on the air, it can quickly play a supporting role, and at the same time, it can play a role in receiving the small parts that roll down; the extension distance of the second layer of horizontal cantilever is greater than the extension distance of the first layer, and it can play a role in receiving when the worker steps on the air and flips back. The second layer adopts a large-aperture protection net, which mainly plays a role in buffering the human body, connecting the joints such as the feet, and increasing the probability of people grabbing the second layer of protection net. The third layer of protection net is closest to the support layer of the bottom layer, can withstand the maximum torque, and extends the farthest outside the floor, which is used to receive heavy objects and workers who are knocked over by the second layer.

Description

Technical Field

[0001] The present invention relates to the technical field of building safety protection. Specifically, it relates to a multi-layer reinforcement protection device. Background Art

[0002] Building construction refers to the production activities in the implementation stage of project construction, which includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. During the construction process, a protective net is required outside the floor to ensure production safety. Currently, a protective net is supported by a scaffolding outside the floor, and the protective net is erected from the bottom, with low load-bearing capacity and poor protection quality. Workers need to manually lap the protective net at a high altitude outside the floor, which instead poses a risk of falling. Summary of the Invention

[0003] In view of the above technical problems in the related art, the present invention provides a multi-layer reinforcement protection device that can solve the above problems.

[0004] To achieve the above technical objectives, the technical solution of the present invention is realized as follows:

[0005] A multi-layer reinforcement protection device includes a counterweight box. A drive motor is provided inside the counterweight box. The drive motor is connected to a support cantilever through a gear transmission. The support cantilever is sequentially provided with a first lifting assembly, a second lifting assembly, and a third lifting assembly from top to bottom. A first horizontal cantilever, a second horizontal cantilever, and a third horizontal cantilever are respectively connected to the first lifting assembly, the second lifting assembly, and the third lifting assembly. Protective nets are connected to the sides of the first horizontal cantilever, the second horizontal cantilever, and the third horizontal cantilever.

[0006] Further, the output shaft of the drive motor is connected to a first bevel gear, and a second bevel gear is provided on the support cantilever. The first bevel gear and the second bevel gear are meshed and connected.

[0007] Further, the support cantilever is a lead screw structure, and the first lifting assembly, the second lifting assembly, the third lifting assembly and the support cantilever are all ball screw structures.

[0008] Further, reinforcing rods are connected to the first horizontal cantilever, the second horizontal cantilever, and the third horizontal cantilever.

[0009] Further, the upper and lower ends of the support cantilever are respectively rotatably connected to an upper base and a lower base.

[0010] Further, the protective net connected to the first horizontal cantilever is a fine-mesh protective net, and the protective net connected to the second horizontal cantilever is a large-aperture protective net.

[0011] Furthermore, the length of the third horizontal cantilever is greater than the length of the second horizontal cantilever; and the length of the second horizontal cantilever is greater than the length of the first horizontal cantilever.

[0012] The beneficial effects of the present invention are as follows: the application adopts a multi-layer height design which can provide buffering and insurance for people in three times. The first layer is a dense-mesh protective net, which is closer to the upper floor and has a shorter horizontal cantilever. When a worker steps on empty space, it can quickly provide support and at the same time, it can receive small parts that roll down. The second layer has a horizontal cantilever with a greater extension distance than the first layer. When a worker steps on empty space and flips over, it can receive the parts. The second layer adopts a large-aperture protective net, which mainly serves to buffer the human body, connect the feet and other joints, and increase the probability of a person grabbing the second layer of protective net. The third layer of protective net is closest to the bottom support layer and can withstand the maximum torque. At the same time, it extends the farthest outside the floor to receive heavy objects and workers who are knocked over by the second layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0020] like Figure 1-2 As shown, a multi-layer reinforced protective net according to an embodiment of the present invention includes a counterweight box 1, a drive motor 2 is provided in the counterweight box 1, and the drive motor 2 is connected to the support cantilever 3 through a gear transmission. The support cantilever 3 is provided with a first lifting component 4, a second lifting component 5 and a third lifting component 6 from top to bottom, and the first lifting component 4, the second lifting component 5 and the third lifting component 6 are respectively connected to the first horizontal cantilever 7-1, the second horizontal cantilever 7-2, and the third horizontal cantilever 7-3, and the sides of the first horizontal cantilever 7-1, the second horizontal cantilever 7-2 and the third horizontal cantilever 7-3 are all connected to a protective net 14.

[0021] In one embodiment of the present invention, the driving motor 2 drives the first bevel gear 8 to rotate, driving the second bevel gear 9 to rotate, thereby driving the supporting cantilever 3 to rotate. The first lifting assembly 4, the second lifting assembly 5, the third lifting assembly 6 and the supporting cantilever 3 are all ball screw structures. The supporting cantilever 3 rotates to drive the first lifting assembly 4, the second lifting assembly 5, and the third lifting assembly 6 to rise to a suitable position. Furthermore, electric locking parts are provided on the first lifting assembly 4, the second lifting assembly 5, and the third lifting assembly 6, which can be driven respectively to adjust to a suitable height relative to each other.

[0022] In one embodiment of the present invention, the first layer is a dense mesh layer, which is closer to the upper floor and has a shorter cantilever. When a worker steps on empty space, it can quickly provide support and at the same time receive small parts that roll down. The second layer uses a larger hollow protective net, which mainly serves to cushion the human body and connect joints such as the feet to facilitate people to grasp. Because the second layer is located in the middle, and the middle section has a larger torque on the supporting cantilever 3, the larger hollow protective net can reduce the weight.

[0023] In one embodiment of the present invention, the reinforcing rod 10, the horizontal cantilever and the supporting cantilever 3 form a triangular stable structure, making the horizontal cantilever more stable.

[0024] In one embodiment of the present invention, two protective devices of the present application are symmetrically arranged at the opening of the floor 13 in the floor, the upper base 11 and the lower base 12 are against the floor 13, the length of the third horizontal cantilever 7-3 is greater than the length of the second horizontal cantilever 7-2; the length of the second horizontal cantilever 7-2 is greater than the length of the first horizontal cantilever 7-1, the distance a between the first horizontal cantilever 7-1 and the second horizontal cantilever 7-2 is less than the distance b from the second horizontal cantilever 7-2 to the second horizontal cantilever 7-2, and less than the distance c from the third horizontal cantilever 7-3 to the counterweight box 1, a protective net is set between the symmetrical horizontal cantilevers, and the horizontal cantilever is opened to the outside of the floor opening to prevent workers from falling and being injured by the horizontal cantilever.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
