Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a scaffold with a safety protection structure. Background Art

[0002] In aerial work such as construction, maintenance and decoration, the scaffolding is a working platform for workers to operate and move, and provides stable support and balance, which helps to improve the safety level of the overall construction site. (Publication No. CN214034645U rotates by holding the handle, and then the second bevel gear rotates under force, thereby driving the first bevel gear to rotate, so that the screw rotates, and then the movable plate on the screw through the threaded movable sleeve moves downward in the first cavity, thereby driving the cone head plate to move downward. When it moves to a certain position, the cone head plate is inserted into the soil, thereby increasing the contact area between the device and the soil) The particularly clear directionality exposes at least the following defects in use:

[0003] 1. When the scaffolding is erected on the exterior wall, the workers may forget their tools on the lower level. It may be inconvenient to move directly to the lower level to retrieve the tools due to space limitations, and walking up the stairs may take a lot of time. Therefore, a scaffolding that can be quickly moved to the lower level is needed.

[0004] 2. In order to ensure the safety of workers, handrails, railings, safety nets and other facilities are usually provided, but most safety protection structures may be inconvenient to operate or easy to loosen. Therefore, a scaffolding with an easy-to-operate safety protection structure is needed.

[0005] 3. In the past, scaffolding was placed on the soil to improve the stability of the device by turning the handle to drive the cone head plate to be inserted into the ground. However, if multiple legs need to be adjusted one by one, the efficiency may be low due to the large workload. Therefore, a scaffolding that can be quickly connected to the ground is needed.

[0037] Beneficial effects:

[0038] 1. By setting up a flap and a limit rod, when the staff needs to go to the lower scaffolding to get tools, they can unscrew the limit rod. After taking out the limit rod, the flap rotates downward due to its own gravity. The staff can pass through the space vacated by the flap and move up and down by climbing the ladder, so as to quickly get the tools forgotten on the lower level, improve work efficiency, and then go upstairs by climbing the ladder. The user drives the flap to rotate upward through the pull rod and fixes the flap again through the limit plate to avoid accidents caused by people stepping on empty space.

[0039] 2. By setting guardrails, protective nets and fixing pins, the protective nets are usually set on both sides below the top plate. When the workers need guardrails as protective measures during construction, the fixing pins can be moved inward, and the workers pull the guardrails upward. When the limit plate at the bottom of the protective net moves to the bottom of the top plate, the workers push the fixing pins into the positioning holes to fix the protective net. This solution is simple and convenient, the structure is relatively stable, and the safety of the scaffolding is improved.

[0040] 3. By setting the connecting block and the connecting rod, when it is necessary to improve the connectivity between the scaffolding and the ground, the staff will align the slots at both ends of the connecting rod with the connecting block, fit it with it, rotate the limit sleeve, and through the limit sleeve closed loop, the staff rotates the connecting rod to drive the connecting block and the active bevel gear to rotate, thereby driving the driven bevel gear and the screw to rotate, and then driving the threaded sleeve and the ground cone to rotate downward, thereby quickly strengthening the connectivity between the scaffolding and the ground and improving work efficiency.

DETAILED DESCRIPTION

[0047] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0048] Example: Figure 1 As shown, a scaffold with a safety protection structure includes two support frames 1 with a reinforcing rod 2 between them to improve stability, a ladder 101 is arranged on the inner side of the support frame 1 for the convenience of workers to go up and down, a top plate 3 is arranged on the top of the support frame 1 for workers to walk and work, and guardrails 6 and protective nets 601 are arranged on both sides of the top plate 3 to prevent objects from falling, provide stable support, and protect the safety of workers.

[0049] like Figure 2 As shown, it includes: movable grooves 302 are symmetrically opened inside the top plate 3 to allow the protective net 601 to move up and down, and a fixing pin 303 is inserted into the positioning hole 603 in the middle of the protective net 601 for limiting the position, and the flap 4 is rotatably connected to the top plate 3, and the limiting rod 5 passes through the first connecting block 301 at the top of the top plate 3, and is finally screwed into the second connecting block 401 at the top of the flap 4, thereby combining the flap 4 and the top plate 3 into one, and a pull rod 402 is provided at the top of the second connecting block 401, which is convenient for the staff to drive the flap 4 to rotate through the pull rod 402.

[0050] like Figure 3As shown, it includes: the protective net 601 is adapted to the movable groove 302, and the size of the guardrail 6 and the limiting plate 602 is larger than the movable groove 302, which can limit the movable range of the protective net 601 to ensure stability. A positioning hole 603 is opened in the middle of the protective net 601 to facilitate the staff to limit the protective net 601 through the fixed positioning pin 303.

[0051] like Figure 4 As shown, it includes: the staff places the connecting block 701 in the slots 1001 at both ends of the connecting rod 10, and rotates the limit sleeve 1003 to prevent the connecting rod 10 from falling off. The staff rotates the connecting rod 10 to drive the active bevel gear 7 to rotate, and then drives the screw 801 at the bottom end of the driven bevel gear 8 to rotate, so that the threaded sleeve 9 drives the ground cone 901 to rotate downward and insert into the ground, thereby improving the connectivity between the scaffolding and the ground. This solution can drive two adjacent ground cones 901 to dive through the connecting rod 10, which is more effective than the previous adjustment through the handle alone.

[0052] In this implementation scheme: the working principle of the limit rod, the flap and the driven bevel gear are existing technologies and belong to common knowledge in the field. They are only used without modification, so they will not be described in detail.

[0053] Working principle: the staff forms a scaffold through the support frame 1, the reinforcing rod 2 and the top plate 3, places the connecting block 701 in the slots 1001 at both ends of the connecting rod 10, and rotates the limiting sleeve 1003 to prevent the connecting rod 10 from falling off. The staff rotates the connecting rod 10 to drive the active bevel gear 7 to rotate, and then drives the screw 801 at the bottom end of the driven bevel gear 8 to rotate, so that the threaded sleeve 9 drives the ground cone 901 to rotate downward and insert into the ground, thereby improving the connectivity between the scaffold and the ground. The staff can climb with the help of the ladder 101 and pull the fixing pin 303 to cancel the limit on the protective net 601. The staff pulls the guardrail 6 upward. When the limiting plate 602 at the bottom of the protective net 601 moves to the bottom of the top plate 3, the staff The worker pushes the fixing pin 303 and inserts it into the positioning hole 603 to fix the protective net 601. The protective net 601 prevents objects from falling and provides stable support to protect the safety of workers. When the worker needs to go to the lower scaffolding to get tools, the limit rod 5 can be unscrewed. After taking out the limit rod 5, the flap 4 rotates downward under its own gravity. The worker can pass through the space vacated by the flap 4 and move up and down through the ladder 101, so as to quickly get the tools forgotten in the lower layer and improve work efficiency. Then, the worker can go upstairs by climbing the ladder. The user drives the flap 4 to rotate upward through the pull rod 402, and fixes the flap 4 again through the limit rod 5 to avoid accidents caused by people stepping on air.
