Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a fall-prevention building construction support. Background Technology

[0002] When plastering or decorating the exterior walls of a building, workers can work directly on the ground for lower sections of the exterior wall, while for higher sections, scaffolding is generally required.

[0003] like Figure 7 As shown, existing support frames generally include a panel and four support legs. The contact area between the support legs and the ground is small. In addition, the four support legs are detachably connected. Therefore, the support frame will sway during use. Although some support frames are equipped with stabilizing structures such as diagonal braces, it is still impossible to completely avoid the swaying of the support frame during use. There is a risk that workers may fall from the support frame.

[0004] The common safety measure is to use a safety belt for protection. However, the requirement for using a safety belt is that it should be suspended high and used low. The existing support frame does not have a suspension position for the safety belt. Furthermore, in order to ensure the flexibility of the workers during operation, the safety belt rope is generally in a slack state. The safety belt can only be effective after the worker falls a certain distance and tightens the rope. Therefore, the protective effect of the safety belt is not good. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this utility model provides a fall-prevention building construction support frame, aiming to improve the safety of the support frame in use.

[0006] The aforementioned fall-prevention construction support includes a support frame, on which a protective frame in the shape of an "8" is provided. There are two protective frames, which are detachably installed at both ends of the support frame. A guard rod is rotatably mounted on each of the two support frames, and a reel is slidably mounted on the guard rod. A safety belt rope is wound around the reel. One end of the protective rod is equipped with a winding device, and the other end is equipped with a locking mechanism.

[0007] In some embodiments, the rewinder includes a take-up shell and a spiral spring; The winding shell is fixedly installed on the protective frame, and the winding shell has a mounting cavity, in which a spiral spring is installed. The end of the protective rod extends into the mounting cavity and is fixedly connected to one end of the spiral spring, while the other end of the spiral spring is fixedly connected to the winding shell.

[0008] In some embodiments, the locking mechanism includes an outer cover, a mounting block, a gate block, and a centrifugal spring; The outer cover has a circular friction cavity inside, and a mounting block is rotatably mounted inside the friction cavity. A gate block is hinged to the mounting block, and three gate blocks are arranged around the rotation axis of the mounting block. The gate block has an arc-shaped portion and a connecting portion. The end of the connecting portion is hinged to the mounting block. The arc-shaped portion is hinged to one end of the centrifugal spring, and the other end of the centrifugal spring is hinged to the mounting block. The end of the protective rod extends into the friction cavity and is fixedly connected to the mounting block.

[0009] In some designs, the outer circumferential surface of the arc-shaped portion is provided with a first tooth pattern; The inner wall of the friction cavity is provided with a second tooth pattern.

[0010] In some designs, the protective rod has a square cross-section, and the center of the reel has a mounting hole that matches the shape of the protective rod, through which the protective rod passes.

[0011] In some embodiments, the support frame is provided with a connecting pipe, and the connecting pipe is provided with a first connecting hole extending radially therefrom; The lower end of the protective frame is provided with a connecting rod, and the connecting rod is provided with a second connecting hole extending radially therefrom; The connecting tube is inserted into the connecting rod, thereby detachably mounting the protective frame onto the support frame.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0018] like Figure 1 As shown, this application provides a fall-prevention construction support frame, including a support frame 1. The support frame 1 is equipped with a protective frame 2 in a figure-eight shape. There are two protective frames 2, detachably installed at both ends of the support frame 1. Specifically, the support frame 1 has four connecting pipes 11, and the lower end of the protective frame 2 has a connecting rod 21. During installation, the protective frame 2 is placed on the support frame 1, and the connecting rod 21 is inserted into the connecting pipe 11. During disassembly, the protective frame 2 is lifted upwards to separate the connecting pipe 11 from the connecting rod 21. In some specific embodiments, such as... Figure 6As shown, the connecting pipe 11 is provided with a first connecting hole 12 extending radially therefrom; the connecting rod 21 is provided with a second connecting hole 22 extending radially therefrom; when the connecting pipe 11 is inserted into the connecting rod 21, a locking rod 8 is used to pass through the first connecting hole 12 and the second connecting hole 22, so that the connecting pipe 11 and the connecting rod 21 form a fixed connection, effectively preventing the protective frame 2 from accidentally falling off and improving the installation firmness of the protective frame 2.

[0019] The top of the protective frame 2 is provided with a bearing seat, and the protective rod 3 is mounted on the bearing seat through a bearing, thereby rotatably mounting the protective rod 3 on the two support frames 1. A roller 4 is slidably mounted on the protective rod 3, specifically, as shown in... Figure 5 As shown, the protective rod 3 has a square cross-section. The winding wheel 4 has a mounting hole 41 in the middle that matches the shape of the protective rod 3. The protective rod 3 passes through the mounting hole 41, so that the winding wheel 4 can slide on the protective rod 3 but cannot rotate. In other words, when the winding wheel 4 rotates, it will drive the protective rod 3 to rotate. It is conceivable that lubricating oil can be applied to the surface of the protective rod 3 and the surface of the protective rod 3 and the inner wall of the mounting hole 41 can be polished smooth to ensure that the winding wheel 4 can slide smoothly on the protective rod 3.

[0020] The pull rope of the safety belt 5 is wound on the reel 4; one end of the guard rod 3 is equipped with a rewinder 6. When the pull rope of the safety belt 5 is pulled out, the reel 4 and the guard rod 3 rotate counterclockwise. After the pull rope of the safety belt 5 is released, the rewinder 6 can drive the guard rod 3 to rotate clockwise, thereby driving the reel 4 to rotate clockwise, and then rewinding the pull rope of the safety belt 5 back onto the reel 4; the other end of the guard rod 3 is equipped with a locking mechanism 7. When the pull rope of the safety belt 5 is pulled out quickly, the locking mechanism 7 is activated, thereby locking the guard rod 3. When the pull rope of the safety belt 5 is pulled out slowly, the locking mechanism 7 does not activate.

[0021] When workers are working on support frame 1, they fasten safety belts 5 around their bodies. The rope of safety belt 5 is pulled out from reel 4. As the distance between the worker and reel 4 decreases, the rope of safety belt 5 is wound back onto reel 4 under the drive of rewinder 6, thus keeping the rope of safety belt 5 in a relatively taut state. When workers move left or right, the safety belt 5 drives reel 4 to slide left and right along guardrail 3, keeping reel 4 basically above the worker. When workers bend over or lean forward on support frame 1, the rope of safety belt 5 is pulled out from reel 4 at a slower speed, allowing workers to work flexibly on support frame 1. If a worker falls, the speed at which the rope of safety belt 5 is pulled out from reel 4 increases dramatically, locking mechanism 7 activates, locking guardrail 3, and the rope of safety belt 5 can no longer be pulled out, thus holding the worker back and effectively preventing a fall, thus significantly improving the safety of workers working on support frame 1.

[0022] In this embodiment, as Figure 2 As shown, the winding device 6 includes a winding shell 61 and a spiral spring 62; the winding shell 61 is fixedly installed on the protective frame 2, and the winding shell 61 has a mounting cavity 611 inside, and the spiral spring 62 is installed inside the mounting cavity 611; the end of the protective rod 3 extends into the mounting cavity 611 and is fixedly connected to one end of the spiral spring 62, and the other end of the spiral spring 62 is fixedly connected to the winding shell 61.

[0023] Thus, when the safety belt 5 is pulled off the reel 4, the guard bar 3 rotates counterclockwise, the spiral spring 62 is tightened, and the safety belt 5 is taut under the elastic force of the spiral spring 62. When the distance between the worker and the reel 4 decreases, the guard bar 3 is driven to rotate clockwise under the action of the spiral spring 62, thereby rewinding the safety belt 5 back onto the reel 4.

[0024] In this embodiment, as Figure 3 As shown, the locking mechanism 7 includes an outer cover 71, a mounting block 72, a gate block 73, and a centrifugal spring 74; The outer cover 71 has a circular friction cavity 711 inside, and a mounting block 72 is rotatably mounted inside the friction cavity 711. The mounting block 72 is approximately equilateral triangle, and a gate block 73 is hinged to the mounting block 72. Three gate blocks 73 are arranged around the rotation axis of the mounting block 72. The gate block 73 is roughly 7-shaped, with an arc-shaped part 731 and a connecting part 732. The end of the connecting part 732 is hinged to the mounting block 72. The arc-shaped part 731 is hinged to one end of the centrifugal spring 74, and the other end of the centrifugal spring 74 is hinged to the mounting block 72. The end of the protective rod 3 extends into the friction cavity 711 and is fixedly connected to the mounting block 72.

[0025] When the guard rod 3 rotates slowly or not at all, under the action of the centrifugal spring 74, the free end of the arc-shaped part 731 is positioned close to the mounting block 72. The outer circumferential surface of the arc-shaped part 731 does not contact the inner wall of the friction cavity 711, and the mounting block 72 can rotate freely, meaning that the pull rope of the safety belt 5 can be pulled out from the reel 4. When the guard rod 3 rotates quickly, meaning that the pull rope of the safety belt 5 is pulled out quickly from the reel 4, under centrifugal force, the arc-shaped part 731 of the brake block 73 is thrown outward and contacts the inner wall of the friction cavity 711, thereby locking the mounting block 72 and locking the guard rod 3, meaning that the pull rope of the safety belt 5 can no longer be pulled out. In this embodiment, the extension direction of the arc-shaped part 731 is the same as the rotation direction of the protective rod 3 when the rope is pulled out. Thus, when the free end of the arc-shaped part 731 contacts the inner wall of the friction cavity 711, if the protective rod 3 continues to rotate, it will press the arc-shaped part 731 against the inner wall of the friction cavity 711. That is, when the locking mechanism 7 is triggered, as long as the tension on the rope does not loosen, the locking mechanism 7 will always be in the state of locking the protective rod 3.

[0026] In this embodiment, as Figure 4 As shown, the outer circumferential surface of the arc-shaped part 731 is provided with a first tooth 733; the inner sidewall of the friction cavity 711 is provided with a second tooth 712. When the locking mechanism 7 is triggered, the first tooth 733 is engaged with the second tooth 712, effectively ensuring that after the locking mechanism 7 is triggered, as long as the tension on the pull rope does not loosen, the locking mechanism 7 will always be in the state of locking the protective rod 3.
