Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a shearing device for safety ropes and cables. Background Technology

[0002] An electric suspended platform is a type of suspended high-altitude work equipment that is erected on the upper part of a building, suspended along the building facade by steel wire ropes, and driven by a motor to move the suspended platform up and down. Before entering the suspended platform, construction workers must wear safety ropes and fix the safety ropes to the safety buckles on the top of the building to ensure construction safety.

[0003] Currently, when using electric suspended platforms, flexible hoses are usually installed at the corners of the parapet wall to allow safety ropes and cables to be run through, thus serving as a protection measure against shearing of the wiring.

[0004] However, as construction progresses in different locations, the positions of safety ropes and cables need to be adjusted. Therefore, the positions of flexible hoses need to be changed and reinstalled, which takes a long time and is quite complicated, affecting the construction progress and needs to be improved. Utility Model Content

[0015] In a preferred embodiment, the present invention can be further configured such that baffles are provided on both sides of the fixed angle steel.

[0016] In a preferred embodiment, the present invention can be further configured such that: a pressure bar for pressing the safety rope and cable is horizontally arranged above the fixed angle steel, and each of the pair of baffles is provided with a through hole for the pressure bar to pass through.

[0017] In a preferred embodiment, the present invention can be further configured such that: one end of the pressure rod is provided with a handle, and the other end is provided with a retaining ring.

[0021] 2. By setting a rotating positioning rod, the anti-shear device can be folded and stored, making it easy to carry and transport. At the same time, the angle between the fixed angle steel and the movable angle steel can be adjusted according to the shape of the parapet wall, so as to stably clamp and fix it to the parapet wall and increase the stability during use.

[0022] 3. By setting baffles to limit the safety rope and cable, and using pressure bars to fix them, the stability of the safety rope and cable is increased, preventing the safety rope and cable from falling off or shifting, and reducing the safety hazards of wear and tear on the safety rope and cable.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, a shearing device for safety ropes and cables includes a fixed angle steel 1, a movable angle steel 2, a positioning rod 3, a positioning tube 4, and a wing bolt 5.

[0028] like Figure 1 , Figure 2 As shown, fixed angle steel 1 is fastened at the outer corner of the parapet wall, and movable angle steel 2 is fastened at the inner corner of the parapet wall. Fixed angle steel 1 and movable angle steel 2 are used for the safety rope and cable to cross, so as to avoid the safety rope and cable directly contacting the cement surface and reduce wear.

[0029] like Figure 1 , Figure 2 As shown, the corner of the fixed angle steel 1 is set in an arc shape, so that the safety rope and cable can smoothly cross the fixed angle steel 1, reducing the pressure on the safety rope and cable, and further reducing the wear of the safety rope and cable.

[0030] like Figure 1 , Figure 2 As shown, the positioning rod 3 is horizontally set on the fixed angle steel 1, the positioning tube 4 is horizontally set on the movable angle steel 2 and is for the positioning rod 3 to pass through, and the wing bolt 5 is threaded to the positioning tube 4 and is used to press the outer wall of the positioning rod 3 to fix the movable angle steel 2.

[0031] Therefore, by installing easily detachable anti-shear devices at the corners of the parapet wall, safety ropes and cables can cross over the anti-shear devices. The anti-shear devices support the safety ropes and cables, preventing wear and tear. At the same time, the anti-shear devices can be quickly relocated according to the position of the safety ropes and cables, meeting the practical needs of the safety ropes and cables and ensuring the construction progress.

[0032] like Figure 1 , Figure 2 As shown, the lower end face of the positioning rod 3 is provided with a row of forward-facing teeth 31, and the inner wall of the positioning tube 4 is provided with a row of reverse-facing teeth 41. The forward-facing teeth 31 and the reverse-facing teeth 41 are inclined in opposite directions and are used to mesh with each other.

[0033] Therefore, after the positioning rod 3 and the positioning tube 4 slide relative to each other, the mutual meshing of the forward locking teeth 31 and the reverse locking teeth 41 can limit the positioning rod 3 and the positioning tube 4, increase the stability of the connection position between the two, prevent the movable angle steel 2 from loosening, and ensure the stability of the entire device during use.

[0034] like Figure 1 , Figure 2 As shown, a sleeve 11 is rotatably connected to the fixed angle steel 1, the positioning rod 3 passes through the sleeve 11, and an end cap 32 that abuts against the sleeve 11 is provided at the end position to realize the rotational adjustment of the positioning rod 3, thereby enabling the anti-shear device to be folded and stored, making it convenient to carry and transport the anti-shear device.

[0035] At the same time, the angle between the fixed angle steel 1 and the movable angle steel 2 can be adjusted according to the shape of the parapet wall, so that the fixed angle steel 1 and the movable angle steel 2 can be stably attached to both sides of the parapet wall, thereby stably clamping and fixing them to the parapet wall and increasing the stability during use.

[0036] like Figure 1 , Figure 2 As shown, baffles 12 are provided on both sides of the fixed angle steel 1 to limit the safety rope and cable, preventing them from falling off or shifting. A pressure bar 13 is horizontally provided above the fixed angle steel 1 to press the safety rope and cable. Each pair of baffles 12 has a through hole 14 for the pressure bar 13 to pass through, so as to press and fix the safety rope and cable, further preventing them from falling off or shifting.

[0037] like Figure 1 , Figure 2 As shown, a handle 15 is provided at one end of the pressure rod 13, and a retaining ring 16 is provided at the other end, to fix the pressure rod 13 and increase its stability during use. A pull rope 17 is provided between the handle 15 and the baffle 12 to fix the pressure rod 13 and prevent it from being lost during transportation.

[0038] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
