Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety scaffolds for building construction, and more specifically, to a safety scaffold for building construction. Background Art
[0002] The construction site is a complex and ever-changing environment, with various construction operations being carried out in parallel, and there are many safety hazards. Among them, aerial work is one of the links most prone to safety accidents, and scaffolding is an indispensable temporary working platform for aerial work. The safety of scaffolding is directly related to the life safety of construction workers and the quality of the project, so it has always attracted much attention. Traditional scaffolding is mostly built with materials such as steel pipes and fasteners, and is connected and fixed by manual assembly. Among them, the most common fixing method is to use fixed sleeves and follower sleeves to connect the scaffolding's vertical poles, crossbars, diagonal braces and other components. The fixed sleeve is usually welded on the vertical pole, which plays a role in positioning and supporting; the follower sleeve is set on the crossbar or diagonal brace, which can slide along the vertical pole and be locked with the fixed sleeve by bolts or pins, so as to realize the assembly and disassembly of the scaffolding. Although this fixing method is simple and easy, it has some inherent defects. Since the weight and load of the entire scaffolding are concentrated on the fixed sleeve and the follower sleeve, which are the weak links in the scaffolding structure, it is easy to produce stress concentration and local deformation. Especially under the action of external forces, such as wind loads, collision loads, etc., the fixed sleeve and the follower sleeve often become the first "victims", and their connection strength and stability are greatly reduced, and in severe cases, they may even cause the scaffolding to collapse. At the same time, since the height of the scaffolding often reaches tens of meters or even hundreds of meters, the coordination and force transmission between the components have become more complicated. It is obviously not enough to rely solely on the fixed sleeve and the follower sleeve to undertake all the connection tasks. More connection points are needed to share the load and maintain stability. Utility Model Content

[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a safety scaffold for construction, which has the following beneficial effects:
[0016] 1. The wire clamping mechanism realizes the reliable fixation and uniform force of the scaffolding through the cooperation of the fixed sleeve, the follower sleeve, the rotating shaft, the wire rope, the wire clamping tube, the slide, the slider, the retaining spring and the insertion rod. When the wire clamping tube retracts backward, the wire rope drives the slider to slide along the slide through the retaining spring, so that the sliders are close to each other, increasing the clamping force between the retaining spring and the wire rope, thereby ensuring the stability of the fixation. At the same time, the wire rope can evenly apply tension to the follower sleeve and the fixed sleeve, avoiding local stress concentration and improving the safety of the scaffolding.

The fixed sleeve 2 is installed on the fixed plate 1, the rotating shaft 4 is rotatably connected to the follower sleeve 3 and the fixed sleeve 2, the wire rope 5 is attached to the follower sleeve 3 and the fixed sleeve 2, the receiving mechanism is cooperatively connected to the follower sleeve 3 and the wire clamping tube 6, a plurality of slides 7 are provided, and the plurality of slides 7 are respectively installed on the inner walls of the wire clamping tube 6, each slide 7 is slidably connected to the slider 8, the slider 8 is provided with an insertion hole 10, and both ends of the retaining spring 9 Insert rods 101 are installed respectively, and the two insert rods 101 are inserted into the two insertion holes 10 respectively. The retaining spring 9 abuts against the wire rope 5. The follower mechanism is installed on the wire clamping tube 6. The receiving mechanism includes a limit block 11 and a threaded tube 12. A groove 13 is provided on the follower sleeve 3. The limit block 11 is stuck in the groove 13. The threaded tube 12 is threadedly connected to the limit block 11. A hexagonal section 14 is provided on the threaded tube 12. The wire rope 5 is slidably connected in the follower block and the threaded tube 12. A pull block 15 is provided on the wire rope 5, and the pull block 15 abuts against the fixed sleeve 2. The wire clamping tube 6 is rotatably connected in the hexagonal section 14. A fixed disk 16 is provided on the wire clamping tube 6. A thrust bearing 17 is fitted on the fixed disk 16, and the thrust bearing 17 abuts against the hexagonal section 14.
[0029] When the cam 12 is in the state of being moved outward, the locking cam 12 and the locking cam 13 are in the state of being moved outward, so that the locking cam 12 and the locking cam 13 are in the state of being moved outward, and the locking cam 12 and the locking cam 13 are in the state of being moved outward.
[0030] See also Figures 2 to 4As an implementation method of a safety scaffold for construction of a follow-up mechanism: the follow-up mechanism includes a tension spring 18 and a push block 19, a plurality of tension springs 18 are provided, and the plurality of tension springs 18 are respectively installed on a plurality of sliders 8, a push block 19 is installed on the tension spring 18, a rotating sleeve 20 is threadedly provided on the wire clamping tube 6, a push plate 21 is provided on the rotating sleeve 20, the push block 19 abuts against the push plate 21, a resistance rod 22 is provided on the slider 8, the resistance rod 22 is pressed against the wire rope 5, a plurality of resistance rods 22 are provided, and the plurality of resistance rods 22 are respectively installed on the plurality of sliders 8.
[0031] More specifically, since the limit block 11 is stuck in the slot 13, the block and the follower sleeve 3 are limited accordingly, the threaded tube 12 is threadedly connected to the limit block 11, and the rotation of the hexagonal section 14 can drive the threaded tube 12 to rotate in the limit block 11, so that the threaded tube 12 and the limit block 11 are displaced. Since the thrust bearing 17 on the block tube can convert the rotational thrust into a vertical thrust, the stability of the clamping is guaranteed.
[0032] In summary, when the overall equipment is in use or in operation: when fixing, first the wire rope 5 is clamped on the follower sleeve 3 and the fixed sleeve 2, and then the expansion and contraction between the threaded tube 12 and the limit block 11 can drive the wire clamping tube 6 to retract backward. Since multiple clamping blocks are respectively in contact with the wire rope 5, when the wire clamping tube 6 moves outward, the clamping force of the clamping spring 9 and the wire rope 5 can drive the slider 8 to slide along the slide 7, so that multiple sliders 8 retract along the slide 7. When the slider 8 retracts along the slide 7, the clamping of the clamping spring 9 and the wire rope 5 is more stable, so the stability of the clamping can be effectively guaranteed. The wire rope 5 can evenly exert force on the follower sleeve 3 and the fixed sleeve 2, thereby ensuring uniform force at multiple positions, thereby improving the safety of use and avoiding damage. When the clamping spring 9 is still on the wire rope 5 after being untied, the movement of the push block 19 can be driven by the rotation of the rotating sleeve 20, and then the slider 8 is driven to move backward by the tension spring 18, thereby releasing the connection.
[0033] Because the limit block 11 is stuck in the slot 13, the block and the follower sleeve 3 are limited accordingly, and the threaded tube 12 is threadedly connected to the limit block 11. The rotation of the hexagonal section 14 can drive the threaded tube 12 to rotate in the limit block 11, so that the threaded tube 12 and the limit block 11 are displaced. Since the thrust bearing 17 on the block tube can convert the rotational thrust into a vertical thrust, the stability of the clamping is guaranteed.
