Description

Technical Field

[0001] This utility model relates to the field of safety protection, and in particular to a safety protection device for construction scaffolding. Background Technology

[0002] As an indispensable temporary support structure in construction, scaffolding is mainly used to provide a high-altitude working platform for construction workers and facilitate the transfer of materials. In actual construction, the safety protection performance of scaffolding is directly related to the personal safety of construction workers and the continuity of the construction process. In particular, it needs to meet core requirements such as rain protection, protection of the work area, and convenient climbing for personnel.

[0003] Existing safety protection devices for construction scaffolding are mostly temporary rain shelters with fixed heights for rainy weather construction. These are not only cumbersome to assemble and disassemble and inefficient, but their height cannot be flexibly adjusted according to the working height of the scaffolding, resulting in poor adaptability and difficulty in meeting the rain protection needs of different construction stages. Therefore, those skilled in the art have provided a safety protection device for construction scaffolding to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety protection device for construction scaffolding. Through the transmission structure of the screw rod and the moving column, the height of the lifting plate can be flexibly adjusted to adapt to scaffolding operations at different heights, solving the problem of poor adaptability of traditional fixed-height rain shelters. At the same time, when the rain shelter is unfolded, it can quickly form a closed rain shelter area, preventing rainwater from directly washing over the working surface, protecting the safety of construction workers and materials from moisture, and ensuring the continuity of construction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for building scaffolding, comprising a base plate, four pillars arranged in a rectangular pattern on the lower end face of the base plate, a protective plate provided on the upper end face of the base plate, a rainproof device provided at the front center of the upper end face of the protective plate, and a protective structure provided at the rear center side of the protective plate.

[0006] The rainproof device includes a device slot located at the rear center of the upper surface of the protective plate. Rotating columns are rotatably connected to both sides of the center of the front inner wall of the protective plate. Both rotating columns penetrate the front inner wall of the protective plate and extend into the device slot. A transmission belt is fitted around the outer sides of the two rotating columns. Lead screws are provided at both sides of the center of the lower inner wall of the device slot. First umbrella wheels are fitted around the rear center of the outer sides of the two rotating columns. Second umbrella wheels are fitted around the lower center of the outer sides of the two lead screws. Moving columns are fitted around the upper center of the outer sides of the two lead screws. Lifting plates are fitted around the outer sides of the two moving columns. Telescopic rods are provided at both sides of the rear end face of the lifting plate. A cylinder is provided at the rear center of the side of the two telescopic rods that are close to each other. A rainproof cloth is fitted around the outer side of the cylinder. The rainproof cloth is fixedly connected to the output end side of the two telescopic rods at the rear center of both sides.

[0007] With the above technical solution, when the rainproof function needs to be deployed, one of the rotating columns is manually rotated. This rotation, via a transmission belt on the outer side, drives both rotating columns to rotate synchronously. The first umbrella wheels on the two rotating columns rotate with them. Because the first umbrella wheels mesh with the second umbrella wheels on the lead screw, this drives the two lead screws to rotate synchronously. When the lead screws rotate, the movable column on the outer side moves up and down along the lead screw axis, causing the connected lifting plate to rise and fall synchronously. This adjusts the height of the rainproof cloth. After the lifting plate reaches the designated height, the rainproof cloth can be manually pulled. The fabric allows the two telescopic rods to extend synchronously, and their output ends drive the rainproof cloth to stretch backward on both sides, causing the rainproof cloth rolled around the outside of the cylinder to unfold and form a rainproof barrier covering the work area. When retracting, the telescopic rods retract, the rainproof cloth rolls back into the cylinder, and then the lifting plate descends into the device slot to complete the storage. Through the rainproof device and the transmission structure of the screw and the moving column, the height of the lifting plate can be flexibly adjusted to adapt to scaffolding operations of different heights, solving the problem of poor adaptability of traditional fixed-height rainproof canopies. At the same time, when the rainproof cloth unfolds, it can quickly form a closed rainproof area, preventing rainwater from directly washing over the work surface, protecting the safety of construction personnel and materials from moisture, and ensuring the continuity of construction.

[0008] Furthermore, the protective structure includes a rectangular groove located at the front of one side of the upper surface of the protective plate. Three springs are arranged vertically on the inner wall of the front of the rectangular groove. A sliding groove is provided at the rear of one side of the center of the upper surface of the bottom plate. The other ends of the three springs are fixedly connected to a protective railing, which is slidably connected inside the sliding groove. Fixed posts are provided at the rear of the upper center of both sides of the protective railing. Limit sleeves are rotatably sleeved on the outside of the two fixed posts. The limit sleeves are slidably sleeved on the outside of the electric push rod on one side.

[0009] With the above technical solution, when the protective function needs to be activated, the guardrail is pulled to move. As the guardrail moves, it slides backward along the sliding groove. At this time, the three springs in the rectangular groove are stretched, generating elastic tension to assist the guardrail in sliding smoothly. Finally, the guardrail is unfolded to the designated position. Then, the limiting sleeve is put on the outside of the electric push rod to limit the guardrail. When the use is over, simply remove the limiting sleeve from the outside of the electric push rod. The three springs retract and drive the guardrail to return to its original position. The protective structure provides buffering force through the three springs when the guardrail is unfolded and retracted, avoiding structural deformation caused by hard impacts during unfolding and retracting. If construction workers accidentally collide with the guardrail, the springs can absorb part of the impact force, reducing the risk of personnel injury and improving protective safety. At the same time, the design of the limiting sleeve ensures that the guardrail is always in the retracted state when there are no workers on the scaffold. Workers can easily climb the scaffold using the sliding groove, avoiding inconvenience in climbing due to forgetting to retract the guardrail or causing safety hazards due to forgetting to unfold the guardrail, thus improving the automation and reliability of the protective device.

[0010] Furthermore, the device has movable grooves at the upper center of the inner wall of the groove on both sides, and movable blocks at the rear center of the outer side of the two movable columns. The two movable blocks are slidably connected inside the two movable grooves respectively.

[0011] The above technical solution, through the setting of the moving block and the moving groove, prevents the moving column from falling off due to excessive rotation of the lead screw, thereby improving the safety of the device.

[0012] Furthermore, a circular sleeve is provided at the rear center of the lower end face of the output end of both telescopic rods, and an electric push rod is provided at the rear center of both sides of the upper end face of the protective plate.

[0013] The above technical solution involves activating an electric push rod and then placing a circular sleeve on the electric push rod to provide support for the rainproof cloth.

[0014] Furthermore, a fork bracket is provided at the upper center of the side between the two front pillars and the two rear pillars that are close to each other.

[0015] The above technical solution improves the structural stability between the four pillars by using a fork frame.

[0016] Furthermore, multiple rectangular plates are arranged vertically between the two pillars on one side that are close to each other;

[0017] Using the above technical solution, workers can climb onto the scaffolding using multiple rectangular plates arranged vertically.

[0018] Furthermore, the two first parachute wheels are respectively engaged with the two second parachute wheels;

[0019] The above technical solution ensures that the first parachute wheel can drive the second parachute wheel to rotate when the first parachute wheel rotates by meshing with the two second parachute wheels respectively.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the safety protection device for building scaffolding uses a rain-proof device and a transmission structure of screw rod and moving column. The lifting plate can be flexibly adjusted in height to adapt to scaffolding operations of different floor heights, solving the problem of poor adaptability of traditional fixed-height rain shelters. At the same time, when the rain-proof cloth is unfolded, it can quickly form a closed rain-proof area to prevent rainwater from directly washing the working surface, protecting the safety of construction personnel and materials from moisture, and ensuring the continuity of construction.

[0022] 2. In this utility model, the protective structure provides buffering force when the guardrail is unfolded and retracted through three springs, avoiding structural deformation caused by hard impacts during unfolding and retracting. If construction workers accidentally collide with the guardrail, the springs can absorb part of the impact force, reducing the risk of injury and improving safety. At the same time, the design of the limiting sleeve ensures that the guardrail is always in the retracted state when there are no workers on the scaffold. Workers can easily climb the scaffold using the sliding groove, avoiding inconvenience in climbing due to forgetting to retract the guardrail or causing safety hazards due to forgetting to unfold the guardrail, thus improving the automation and reliability of the protective device.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 An embodiment of this utility model is provided: a safety protection device for building scaffolding, including a base plate 1, four pillars 2 arranged in a rectangle on the lower end face of the base plate 1, a protective plate 3 provided on the upper end face of the base plate 1, a rainproof device 4 provided at the front of the center of the upper end face of the protective plate 3, and a protective structure 5 provided at the rear of one side of the center of the protective plate 3.

[0031] like Figure 2 , 3As shown in Figure 4, the rainproof device 4 includes a device groove 401, which is located at the rear center of the upper end face of the protective plate 3. Rotating columns 402 are rotatably connected to both sides of the center of the front inner wall of the protective plate 3. Both rotating columns 402 penetrate the front inner wall of the protective plate 3 and extend into the device groove 401. A transmission belt 403 is fitted onto the outer side of the two rotating columns 402. Lead screws 404 are provided at both sides of the center of the lower inner wall of the device groove 401. First umbrella wheels 405 are fitted onto the rear center of the outer side of each of the two rotating columns 402. Second umbrella wheels 406 are fitted onto the lower center of the outer side of each of the two lead screws 404. A second umbrella wheel 406 is fitted onto the upper center of the outer side of each of the two lead screws 404. The movable columns 407 are connected to two lifting plates 410 on their outer sides. Telescopic rods 411 are located on both sides of the rear center of the lifting plates 410. A cylinder 412 is located on the rear side of the two telescopic rods 411 that are close to each other. A rainproof cloth 413 is connected to the outer side of the cylinder 412. The rainproof cloth 413 is fixedly connected to the output end side of the two telescopic rods 411 on both sides of its rear side. When the rainproof function needs to be activated, one of the rotating columns 402 is manually rotated. This rotation is caused by a transmission belt 403 on the outer side, which drives both rotating columns 402 to rotate synchronously. The first umbrella wheels 405 on the two rotating columns 402 rotate accordingly. The first umbrella wheel 405 meshes with the second umbrella wheel 406 on the lead screw 404, thereby driving the two lead screws 404 to rotate synchronously. When the lead screw 404 rotates, the movable column 407 sleeved on the outer side moves up and down along the axial direction of the lead screw 404, driving the lifting plate 410 connected to it to rise and fall synchronously. This achieves the adjustment of the height of the rainproof cloth 413. After the lifting plate 410 is raised to the specified height, the rainproof cloth 413 can be manually pulled to extend the two telescopic rods 411 synchronously. Their output ends drive the two sides of the rainproof cloth 413 to stretch backward. The rainproof cloth 413, which is rolled up on the outside of the cylinder 412, is unfolded to form a rainproof barrier covering the work area. When it is retracted, the telescopic rod 411 retracts, the rainproof cloth 413 rolls back into the cylinder 412, and then the lifting plate 410 descends into the device slot 401 to complete the storage. Through the transmission structure of the rainproof device 4 with the lead screw 404 and the moving column 407, the lifting plate 410 can be flexibly adjusted in height to adapt to scaffolding operations of different heights, solving the problem of poor adaptability of traditional fixed-height rainproof canopies. At the same time, when the rainproof cloth 413 is unfolded, it can quickly form a closed rainproof area to prevent rainwater from directly washing the work surface, protecting the safety of construction personnel and materials from moisture, and ensuring the continuity of construction.

[0032] like Figure 1 and 3As shown, the protective structure 5 includes a rectangular groove 501 located on one side of the upper end face of the protective plate 3, near the front. Three springs 502 are arranged vertically on the inner front wall of the rectangular groove 501. A sliding groove 503 is located on one side of the center of the upper end face of the base plate 1, near the rear. A protective railing 504 is fixedly connected to the other end of each of the three springs 502. The protective railing 504 is slidably connected inside the sliding groove 503. Fixed posts 505 are located on both sides of the upper rear center of the protective railing 504. Limit sleeves 506 are rotatably connected to the outer sides of the two fixed posts 505. The limit sleeves 506 are slidably connected to the outer side of an electric push rod 415 on one side. When the protective function needs to be activated, the protective railing 504 is pulled to move. As the protective railing 504 moves, it slides backward along the sliding groove 503. At this time, the three springs 502 inside the rectangular groove 501 are stretched, generating elastic tension to assist the protective railing 504 in sliding smoothly. Finally, the protective railing 504 unfolds to the designated position. Next, the limiting sleeve 506 is fitted onto the outside of the electric push rod 415 to limit the guardrail 504. When the use is finished, simply remove the limiting sleeve 506 from the outside of the electric push rod 415. The three springs 502 will retract and drive the guardrail 504 to reset. The protective structure 5 provides buffering force when the guardrail 504 is unfolded and retracted through the three springs 502, avoiding structural deformation caused by hard impacts during unfolding and retraction. If construction personnel accidentally collide with the guardrail 504, the springs 502 can absorb part of the impact force, reducing the risk of personnel injury and improving safety. At the same time, the design of the limiting sleeve 506 ensures that the guardrail 504 is always in the retracted state when there are no workers on the scaffold. Workers can easily climb the scaffold using the sliding groove 503, avoiding inconvenience in climbing due to forgetting to retract the guardrail 504 or causing safety hazards due to forgetting to unfold the guardrail 504, thus improving the automation and reliability of the protective structure 5.

[0033] The device groove 401 has a movable groove 408 at the upper center of the inner wall on both sides, and a movable block 409 at the rear center of the outer side of the two movable columns 407. The two movable blocks 409 are slidably connected inside the two movable grooves 408. The movable blocks 409 and the movable grooves 408 are designed to prevent the movable columns 407 from falling off due to excessive rotation of the lead screw 404, thereby improving the safety of the device.

[0034] Both telescopic rods 411 have a circular sleeve 414 at the rear center of the lower end face of their output ends. Both sides of the upper end face of the protective plate 3 have an electric push rod 415 at the rear center of their upper end faces. By activating the electric push rod 415, the circular sleeve 414 is then placed on the electric push rod 415 to provide support for the rain cover 413.

[0035] A fork frame 6 is provided at the center of the upper part between the two front pillars 2 and the two rear pillars 2 that are close to each other. The fork frame 6 improves the structural stability between the four pillars 2.

[0036] On one side, there are multiple rectangular panels 7 arranged vertically between two pillars 2 that are close to each other. Workers can climb onto the scaffolding by using the multiple rectangular panels 7 arranged vertically.

[0037] The two first parachute wheels 405 are respectively engaged with the two second parachute wheels 406. Through the mutual engagement of the two first parachute wheels 405 and the two second parachute wheels 406, it is ensured that the rotation of the first parachute wheel 405 can drive the rotation of the second parachute wheel 406.

[0038] Working principle: When using the device, the worker first climbs onto the scaffolding using multiple rectangular plates 7 arranged vertically. Then, the worker pulls the guardrail 504 to move it. As the guardrail 504 moves, it slides backward along the sliding groove 503. At this time, the three springs 502 in the rectangular groove 501 are stretched, generating elastic tension, which helps the guardrail 504 to slide smoothly. Finally, the guardrail 504 unfolds to the designated position, and then the limiting sleeve 506 is put on the outside of the electric push rod 415 to limit the guardrail 504.

[0039] When finished using the device, simply remove the limiting sleeve 506 from the outside of the electric push rod 415. The three springs 502 will retract and reset the guardrail 504. The protective structure 5 provides buffering force through the three springs 502 when the guardrail 504 is unfolded and retracted, avoiding structural deformation caused by hard impacts during unfolding and retraction. If construction workers accidentally collide with the guardrail 504, the springs 502 can absorb part of the impact force, reducing the risk of injury and improving safety. At the same time, the design of the limiting sleeve 506 ensures that the guardrail 504 is always in the retracted state when there are no workers on the scaffold. Workers can easily climb the scaffold using the sliding groove 503, avoiding inconvenience in climbing due to forgetting to retract the guardrail 504 or causing safety hazards due to forgetting to unfold the guardrail 504, thus improving the automation and reliability of the protective structure 5.

[0040] When the rainproof function is needed, one of the rotating columns 402 is manually rotated. This rotation drives both rotating columns 402 to rotate synchronously via the transmission belt 403 on the outer side. The first umbrella wheel 405 on the two rotating columns 402 rotates with them. Because the first umbrella wheel 405 meshes with the second umbrella wheel 406 on the lead screw 404, it drives the two lead screws 404 to rotate synchronously. When the lead screws 404 rotate, the movable column 407 on the outer side moves up and down along the axial direction of the lead screw 404, driving the lifting plate connected to it. 410 synchronous lifting: When the lead screw 404 rotates, the movable column 407 sleeved on the outside moves up and down along the axis of the lead screw 404, driving the lifting plate 410 connected to it to lift up and down synchronously, realizing the adjustment of the height of the rainproof cloth 413. After the lifting plate 410 is raised to the specified height, the rainproof cloth 413 is manually pulled to make the two telescopic rods 411 extend synchronously. Their output ends drive the two sides of the rainproof cloth 413 to stretch backward, so that the rainproof cloth 413 wrapped around the outside of the cylinder 412 unfolds to form a rainproof barrier covering the work area.

[0041] When retracted, the telescopic rod 411 retracts, the rainproof cloth 413 rolls back into the cylinder 412, and then the lifting plate 410 descends into the device slot 401 to complete the storage. Through the transmission structure of the rainproof device 4 with the lead screw 404 and the moving column 407, the lifting plate 410 can be flexibly adjusted in height to adapt to scaffolding operations of different floor heights, solving the problem of poor adaptability of traditional fixed-height rainproof canopies. At the same time, when the rainproof cloth 413 is unfolded, it can quickly form a closed rainproof area to prevent rainwater from directly washing the working surface, protecting the safety of construction personnel and materials from moisture, and ensuring the continuity of construction.

[0042] The equipment includes a control panel, which enables the equipment to be started and controlled through a human-machine interface and an electrical control system. Input signal processing converts the operator's instructions into electrical signals, and output signal transmission transmits control signals to various actuators to achieve equipment control. This is a commonly used technical solution in existing control systems and will not be elaborated on further here.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
