[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figures 1 to 10 The present invention provides a guardrail reinforcement device for construction, including: a guardrail body 1, a base 2, a support block 3, a placement slot 4, a support foot 5, a guardrail frame 6, a rotating part, a moving part and a connecting part.

[0043] In this embodiment, the movement of the rotating parts can provide a certain self-locking property for the moving parts and the connecting parts, which helps to ensure excellent stability after the parts are in operation. The rotating parts drive the moving parts to operate, thereby forming a cone-shaped shape in the middle of the guardrail body 1, and having a buffering form and self-locking ability. When not in use, such as during transportation and storage, this method can be folded to reduce the occupied space, which is convenient for transportation and storage. The change in its cone-shaped shape can divert and cut the wind force, as well as guide the wind by tilting, thereby reducing the direct impact of the wind force on the guardrail body 1, reducing the risk of shaking, and achieving the purpose of reinforcement. This method also has the purpose of elastic sliding and telescoping, so that the angle between the two guardrail frames 6 is constantly changing, further buffering the wind force, so that the angle of the two guardrail frames 6 changes to disperse the wind pressure, and improves the stability of the guardrail body 1.

[0044] The rotating component synchronously drives the connecting component to operate, so as to drive the two support blocks 3 to extend, so as to further increase the contact area between the base 2 and the ground. The extended support blocks 3 serve the purpose of bicycle training wheels, further improving the anti-sway and stability capabilities of the base 2, so as to further enhance the stability of the guardrail body 1. When not in use, the two support blocks 3 are retracted into the base 2, which serves the purpose of storage and reduces the large area occupied during transfer and transportation. In addition, since this method uses threaded rotation to extend and retract the support blocks 3, it also has a certain degree of self-locking.

[0045] The guardrail reinforcement device for building construction also includes a locking component.

[0046] In this embodiment: through the operation of the locking component, the guardrail body 1 can be stably locked on the device. The device can implement all-round locking of the guardrail body 1. By horizontally locking the support legs 5 and vertically pressing the guardrail body 1, a firm fixation is achieved to avoid movement and shaking. Compared with the method of only locking the support legs, this multi-directional locking design enhances the stability of the guardrail and can adapt to guardrail right angles of various heights and specifications, thereby improving practicality. After locking, the device can enhance the protection and windproof capabilities of the guardrail body 1, and has an excellent reinforcement effect. The overall operation is convenient and the guardrail body 1 can be excellently locked without multiple complicated operations.

[0047] See also Figure 1-Figure 7 In this embodiment, the rotating component includes:

[0048] The rotary drive unit 40 is fixedly connected to the mounting shell 7 on the upper surface of the base 2, and the rotary drive unit 40 is arranged on the mounting shell 7. The output portion of the rotary drive unit 40 on the lower surface is fixedly connected to the rotating shaft 8, and the outer surface of the rotating shaft 8 is fixedly connected to the worm 9. The inner wall of the mounting shell 7 is fixedly connected to the screw 10, and the outer surface of the screw 10 is fixedly connected to the worm wheel 11, and the worm wheel 11 is meshed with the worm 9.

[0049] In this embodiment: the rotary drive unit 40 can be installed on the top of the mounting shell 7 in the form of a motor, or it can be manually twisted. The rotation of the rotary drive unit 40 drives the rotating shaft 8 and the worm 9 to rotate, and under the meshing transmission, drives the worm wheel 11 to rotate, thereby causing the screw 10 to rotate. Since the transmission between the worm 9 and the worm wheel 11 is self-locking, the operation of the rotary drive unit 40 can provide a certain self-locking force for subsequent mechanisms or components, thereby having an excellent reinforcement effect.

[0050] See also Figure 1-Figure 4 and Figure 7 In this embodiment, the moving parts include:

[0051] The limiting member 13 has a lower surface fixedly connected to the upper surface of the base 2. The threaded portion of the screw 10 is threadedly connected to the moving block 12. The outer surface of the moving block 12 is slidably connected to the inner side of the limiting member 13. The end of the moving block 12 is slidably sleeved with a sleeve block 35. The opposite sides of the inner walls of the moving block 12 and the sleeve block 35 are fixedly connected to a spring 1.

[0052] The two guard net frames 6 are rotatably connected via the connecting shaft 14. An opening is provided at the end of the sleeve block 35 for the connecting shaft 14 to pass through and be rotatably connected thereto. An insertion rod 15 is fixedly connected to the lower surface of the guard net frame 6. A slide groove 16 is provided on the upper surface of the base 2 for the insertion rod 15 to extend into and for the insertion rod 15 to slide. The slide groove 16 is opened along the length direction of the base 2.

[0053] In this embodiment: through the rotation of the screw 10, under the thread transmission and the sliding restriction of the limit member 13, the moving block 12 and the sleeve block 35 are driven to move in the direction away from the worm gear 11, so that the connecting shaft 14 moves synchronously, and because of the connection of the connecting shaft 14, the two guard net frames 6 have the characteristics of hinged connection. When the hinge point moves, the two guard net frames 6 will be arched forward to form a shape similar to a triangle and a cone, and the rod 15 slides in the slide groove 16 to adapt to the deflection of the guard net frame 6, and finally the two guard net frames 6 are connected. Figure 1 In the initial state, the two guard net frames 6 are moved to be arched, thereby achieving a change in the angle between the two guard net frames 6;

[0054] This method has the purpose of folding. When not in use and transported, it can reduce the occupied area, which is convenient for transportation and storage. This method can achieve excellent reinforcement. Through this cone shape, it can reduce the direct effect of wind on the guardrail body 1 to a certain extent, and the wind is diverted and cut through the cone and multiple mesh holes on the guardrail frame 6. From the overall point of view, it can guide the wind blowing horizontally on the guardrail body 1, which helps to reduce the force of the wind directly acting on the guardrail body 1, thereby reducing the shaking and instability of the guardrail body 1 due to the action of wind, thereby achieving the purpose of reinforcement. Moreover, since the guardrail itself The body 1 is mostly hollow or open in design for the purpose of ventilation and drainage. In order to avoid obstruction, a guardrail frame 6 is used to guide and divert the wind to avoid affecting the performance of the guardrail body 1 itself. This method can also serve the purpose of buffering due to the elastic sliding between the sleeve block 35 and the movable block 12. It serves the purpose of diverting and guiding the wind through the cone shape, and can further serve the purpose of wind buffering through elastic sliding, so that when the wind acts on the two guardrail frames 6, the angle between the two guardrail frames 6 can be continuously changed to further buffer this part of the wind, so as to further improve the stability of the guardrail body 1.

[0055] See also Figure 1-Figure 7 In this embodiment, the connecting component includes:

[0056] The first coupling shaft 17 and the swivel shaft 8 penetrate into the interior of the base 2 and are connected to the base 2 in a fixed rotational manner. The lower end of the swivel shaft 8 is connected to the outer surface of the first coupling shaft 17 via a bevel gear transmission mechanism 18. The inner wall of the base 2 is connected to the second coupling shaft 36 in a fixed rotational manner via a support. The outer surface of the second coupling shaft 36 is connected to the outer surface of the first coupling shaft 17 via a pulley transmission mechanism 19.

[0057] Two brackets 20, the lower surface of the bracket 20 is fixedly connected to the inner wall of the base 2, the upper end of the bracket 20 is fixedly connected to a screw rod 21, the opposite sides of the two screw rods 21 are fixedly connected to a bevel gear 1 22, the outer surface of the connecting shaft 2 36 is fixedly connected to a bevel gear 23, the tooth grooves of the two bevel gears 1 22 are meshed with the tooth grooves of the bevel gear 23, and the side of the support block 3 is provided with an internal thread groove for the screw rod 21 to penetrate and be threadedly connected thereto.

[0058] In this embodiment, the rotation of the rotating shaft 8 drives the connecting shaft 17 to rotate under the transmission of the bevel gear transmission mechanism 18, and drives the connecting shaft 2 36 and the bevel gear 2 23 under the transmission of the pulley transmission mechanism 19, so that the bevel gear 1 22 and the screw 2 21 rotate. Due to the sliding restriction of the base 2 on the support block 3 and the thread transmission, the two support blocks 3 are synchronously moved in opposite tilt directions, so that the two support blocks 3 are extended, thereby further increasing the contact area between the base 2 and the ground, and the extended support blocks 3 serve the purpose of the bicycle training wheel, further improving the anti-sway and stability ability of the base 2, thereby further improving the stability of the guardrail body 1, and when not in use, the two support blocks 3 are retracted into the base 2, thereby achieving the purpose of storage, so as to reduce the large occupied area during transfer and transportation, and this method also has a certain self-locking property because the support blocks 3 are extended and retracted by thread rotation.

[0059] See also Figure 1-Figure 4 、 Figure 8 and Figure 10 ,In this embodiment, the locking component includes a vertical component and a horizontal component;

[0060] The vertical components include:

[0061] Two elastic telescopic members 24, the lower end of the elastic telescopic member 24 and the base 2

[0062] The upper surface of the elastic member 24 is fixedly connected, the upper end of the elastic member 24 is L-shaped, and the upper end of the elastic member 24 is slidably connected to the pressure block 25;

[0063] A screw rod 37 is slidably connected to the upper surface of the pressing block 25, and a handle portion 38 is fixedly connected to the upper end of the screw rod 37. An annular groove is provided inside the pressing block 25, and a ring block 33 is fixedly connected to the outer surface of the screw rod 37. The ring block 33 is located in the annular groove. A plurality of threaded sleeves 34 are provided on the inner wall of the elastic telescopic member 24, and the threaded sleeves 34 are provided along the horizontal direction of the L-shaped end of the elastic telescopic member 24.

[0064] The transverse components include:

[0065] Two elastic telescopic members 26, the lower surface of the elastic telescopic member 26 is fixedly connected to the inner wall of the base 2, and the telescopic portion of the upper end of the elastic telescopic member 26 is fixedly connected to the support block 27, the support block 27 is located in the placement groove 4, and the placement groove 4 has a notch for the support block 27 to slide, and the upper surface of the support block 27 is used to contact the support leg 5;

[0066] There are two groups of clamping blocks 28, and the clamping blocks 28 correspond to the support feet 5 at the placement slots 4. There are two clamping blocks 28 in each group, which are located on both sides of the support feet 5. The inner wall of the base 2 is provided with two openings for the clamping blocks 28 to pass through and be slidably connected thereto. The clamping blocks 28 and the opposite sides of the inner wall of the base 2 are jointly fixedly connected with elastic telescopic parts three 29. Two groups of rotating rods 30 are connected to the inner wall of the base 2 with fixed axes. There are two rotating rods 30 in each group. A pressure plate 31 is fixedly connected to the outer surface of the rotating rod 30. The pressure plate 31 and the opposite sides of the inner wall of the base 2 are jointly fixedly connected with a torsion spring 32. The torsion spring 32 is sleeved on the rotating rod 30. The lower end of the pressure plate 31 is used to press against the lower surface of the support block 27, and the upper end of the pressure plate 31 is used to press against the side of the clamping block 28.

[0067] In this embodiment, the guardrail body 1 is first placed on the placement groove 4. At this time, the upper end of the elastic telescopic member 1 24 is pulled to drive the elastic telescopic member 1 24 to move vertically to adapt to guardrail bodies 1 of different heights. Then, the handle 38 is used to drive the pressing block 25 to extend. As a result, the extended pressing block 25 is elastically extended by the elastic telescopic member 1 24, so that the lower surface of the pressing block 25 abuts against the upper surface of the guardrail body 1, thereby applying vertical pressure to the guardrail body 1.

[0068] When the pressing block 25 needs to be moved out, it is only necessary to lift the handle portion 38 and drive the handle portion 38 to move outward, thereby driving the pressing block 25 to continue to extend. When it is extended to a sufficient length, the handle portion 38 is pressed downward, so that the screw rod 37 is inserted downward into the threaded sleeve 34, and the handle portion 38 is twisted to rotate the screw rod 37 to screw into the threaded sleeve 34. A scale or other prompt method can be set at the upper end of the elastic telescopic member 24 to indicate whether the screw rod 37 is facing the threaded sleeve 34. This method only requires driving the handle portion 38 to achieve the height change of the vertical component and the extension of the vertical component and to place it on the guardrail body 1. It has excellent convenience and does not require multiple operations. The overall operation can be achieved by one person. It also has an excellent locking effect through thread locking, which is more practical.

[0069] As the guardrail body 1 is exerted with a downward force, the support leg 5 of the guardrail body 1 will move downward, thereby pressing the support block 27 to move downward and pressing the elastic telescopic member 2 26. However, the elastic force of the elastic telescopic member 26 is not enough to offset the gravity of the guardrail body 1 and the pressure exerted on the guardrail body 1 by the elastic telescopic member 1 24, thereby causing the elastic telescopic member 26 to contract. The downwardly moving support block 27 will press against the lower end of the pressure plate 31, thereby causing the pressure plate 31 to deflect with the rotating rod 30 as the center of the circle, thereby causing the upper end of the pressure plate 31 to deflect accordingly, thereby causing the upper end of the pressure plate 31 to press against the clamping block 28 to move toward the support leg 5, and finally causing the two clamping blocks 28 to synchronously clamp the support leg 5 inwardly.

[0070] This method can achieve the purpose of all-round locking of the guardrail body 1, so that the guardrail body 1 is locked on this device, so as to reinforce the guardrail body 1 under the action of this device, and can provide the guardrail body 1 with a lateral locking force of the support legs 5 and a vertical pressing force to achieve an all-round locking and stable effect. Different from the method of only locking the support legs 5, this multi-directional locking method helps to stabilize the guardrail body 1 on this device, and is not prone to unstable situations such as movement and shaking, and can adapt to guardrails of various heights to a certain extent. Since a larger horizontal component is provided, it can adapt to the locking use of guardrail support legs 5 of various specifications to a certain extent, so as to improve the practicality of this device. After the guardrail body 1 is locked on this device, the protection and windproof capabilities of the guardrail body 1 can be improved based on this device, and unstable situations such as shaking and moving of the guardrail body 1 can be avoided, which has an excellent reinforcement effect.

[0071] See also Figures 1-6 In this embodiment, the base 2 is arranged in a trapezoidal shape, and anti-slip lines are provided on the lower surface of the base 2.

[0072] In this embodiment: first, the base 2 is set to a trapezoidal shape with a larger bottom and a smaller top. After the base 2 is connected to the guardrail body 1, the contact area between the guardrail body 1 and the ground can be directionally increased, which can prevent the guardrail body 1 from tipping over after being affected by external forces during use, thereby improving the reinforcement and stability of the guardrail body 1. The trapezoidal shape with a larger bottom and a smaller top can have a certain wind-guiding effect to a certain extent through the inclined form of the trapezoid, which can improve the wind resistance of the entire guardrail, so as to enhance the reinforcement and stability of the device, thereby further improving the reinforcement stability of the guardrail, and the design of the anti-slip pattern can increase the contact friction between the base 2 and the ground to improve the contact stability, and avoid the guardrail body 1 from easily moving under the action of external forces, so as to enhance the reinforcement capability.
