Description
Technical Field
[0001] This utility model relates to the field of building construction equipment technology, specifically a green building high-altitude construction protection device. Background Technology
[0002] Green building refers to buildings that maximize resource conservation, environmental protection, and pollution reduction throughout their entire life cycle, providing people with healthy, suitable, and efficient living spaces, and coexisting harmoniously with nature. When performing high-altitude operations in green buildings, protective devices are needed to ensure the personal safety of operators. However, the existing high-altitude construction protective devices for green buildings do not have high safety performance and cannot withstand large impact forces when falling from heights.
[0003] As disclosed in announcement number CN221461894U, a green building high-altitude construction safety device includes multiple fixed components, each with an intercepting protective net. Each fixed component includes a fixed column, and a fixing ring is fixedly connected to the outer wall of one end of each column. Each column has a through-hole movable cavity in its inner wall. The fixed column can be installed in a suitable position using fixing bolts and fixing rings. The extension length of the telescopic column can then be adjusted by adjusting bolts. Finally, the first and second limiting bolts connect and limit the intercepting protective net, completing the installation of the net. This provides high-altitude protection during green building construction. The device itself is lightweight, reducing the weight burden on the green building while protecting it from safety hazards during high-altitude construction. However, the safety performance of the intercepting protective net within this green building high-altitude construction safety device is not high; it cannot withstand significant impact forces during a fall from a height. Utility Model Content
[0004] The purpose of this utility model is to provide a green building high-altitude construction protection device to solve the problem that the existing green building high-altitude construction protection devices are not very safe to use and cannot withstand large impact forces when falling from a height.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a green building high-altitude construction safety device, comprising: a hoisting safety plate, a middle limit roller passing through one outer end of the hoisting safety plate, an upper limit roller passing through the inner part of the upper part of the outer hoisting safety plate, a hoisting steel cable passing through the inner part of the lower part of the hoisting safety plate, a fall arrestor shell fixedly fitted at one lower end of the hoisting steel cable, a slider adjustment frame fixedly installed on the inner side of the fall arrestor shell, an adjustment rotating sleeve rotatably connected to one upper end of the inner part of the fall arrestor shell, a middle rotating shaft rotatably connected inside the slider adjustment frame, and a double ratchet coiled rope roller rotatably connected to one outer end of the middle rotating shaft via a coil spring.
[0006] As a further embodiment of this utility model: the hoisting protective plate includes a Z-shaped protective plate body, a middle roller insertion hole is provided through the middle of the Z-shaped protective plate body, an upper roller through hole is provided through the upper part of the Z-shaped protective plate body, and a hoisting through hole is provided through the lower part of the Z-shaped protective plate body.
[0007] As a further embodiment of this utility model: the middle limiting roller includes a middle roller plate, a middle roller limiting rod is fixedly provided on one side below the middle roller plate, the middle limiting roller body is movably sleeved on one end of the outer side of the middle roller limiting rod, and a through hole is provided in the upper part of the middle roller plate.
[0008] As a further embodiment of this utility model: the upper limit rotating roller includes an upper roller shaft, an upper limit rotating roller body is movably sleeved at the middle of one end of the upper roller shaft, and a limit nut is screwed to the side of one end of the upper roller shaft.
[0009] As a further embodiment of this utility model: the fall arrestor shell includes a fall arrestor housing, a hoisting hole seat is fixedly provided on the upper outer side of the fall arrestor housing, a rotating sleeve limiting groove is opened through the upper interior of the fall arrestor housing, a ratchet triangular locking block is fixedly provided on one side of the interior of the fall arrestor housing, and a rope threading hole is opened through the middle of the lower part of the fall arrestor housing.
[0010] As a further embodiment of this utility model: the slider adjustment frame includes an adjustment frame limiting frame, an adjustment screw is screwed through the upper part of the adjustment frame limiting frame, a hexagonal extension rod is fixedly provided at one end of the upper part of the adjustment screw, a slider is slidably limited and slidably provided on the upper inner side of the adjustment frame limiting frame, a shaft adapter groove is provided through the slider, and a spring-loaded elastic element is fixedly provided between the lower inner side of the adjustment frame limiting frame and the lower part of the slider.
[0011] As a further embodiment of this utility model: the adjusting rotating sleeve includes a rotating sleeve body, a hexagonal shallow groove is formed through the upper part of the rotating sleeve body, a transition limiting ring is fixedly provided on the upper outer side of the rotating sleeve body, and a hexagonal deep groove is formed inside the lower part of the rotating sleeve body.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, the upper limit roller body is placed above the I-beam, and two sets of middle limit roller bodies are placed on both sides of the middle of the I-beam. Then, the two sets of hoisting protective plates are aligned on both sides of the upper limit roller body and the middle limit roller body. The upper roller shaft is then passed through the upper roller through hole, the middle roller plate through hole, and the upper limit roller body. Next, the middle roller limit insert rods at one end of the two sets of middle roller plates are aligned with the middle roller insert holes and the inside of the middle limit roller body, and the middle roller plate through hole is fitted on the outside of the upper roller shaft. Finally, the limit nuts are screwed on both sides of the upper roller shaft to complete the installation of the hoisting protective components. In this way, the hoisting rope can be passed through the hoisting through hole to achieve the effect of upper limit hoisting protection.
[0014] In this invention, by adding a fall arrestor between ropes, or by using a separate hoisting protection mechanism to suspend the fall arrestor, the fall arrestor will not lock under slow pulling conditions. When falling, the rope will quickly pull down the double ratchet winding rope roller and the slider through the central rotating shaft, causing the double ratchet winding rope roller to be locked by the ratchet triangular block. This achieves the fall arrest effect. Furthermore, by alternately rotating two sets of adjusting rotating sleeves, the hexagonal extension rod sliding inside the hexagonal deep groove drives the adjusting screw to rotate. This allows the adjustment of the length of the adjusting screw to be screwed in, thereby restricting its position. This allows for quick adjustment of the distance between the double ratchet winding rope roller and the ratchet triangular block, thus quickly adjusting the fall arrestor trigger stroke.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0027] Reference Figures 1 to 3 In this embodiment of the utility model, a green building high-altitude construction protection device includes: a hoisting protective plate 1, a middle limit roller 2 passing through one outer end of the hoisting protective plate 1, an upper limit roller 3 passing through the inner part of the upper part of the outer hoisting protective plate 1, a hoisting steel cable 4 passing through the inner part of the lower part of the hoisting protective plate 1, a fall arrestor shell 5 being fixedly sleeved at one lower end of the hoisting steel cable 4, a slider adjustment frame 6 being fixedly installed on the side inside the fall arrestor shell 5, an adjustment rotating sleeve 7 being rotatably connected to one upper end inside the fall arrestor shell 5, an intermediate rotating shaft 8 being rotatably connected inside the slider adjustment frame 6, and a double ratchet coiled rope roller 9 being rotatably connected to one outer end of the intermediate rotating shaft 8 via a coil spring.
[0028] Reference Figure 4 The hoisting protective plate 1 includes a Z-shaped protective plate body 10, with a middle roller insertion hole 11 through the middle of the Z-shaped protective plate body 10, an upper roller through hole 12 through the upper part of the Z-shaped protective plate body 10, and a hoisting through hole 13 through the lower part of the Z-shaped protective plate body 10.
[0029] Reference Figure 5 The middle limiting roller 2 includes a middle roller plate 20. A middle roller limiting rod 21 is fixedly installed on one side below the middle roller plate 20. A middle limiting roller body 22 is movably sleeved on one side of the middle roller limiting rod 21. A through hole 23 is opened in the upper part of the middle roller plate 20.
[0030] Reference Figure 6The upper limit roller 3 includes an upper roller shaft 30, with an upper limit roller body 31 movably sleeved at the middle of one end of the upper roller shaft 30, and a limit nut 32 screwed to the side of one end of the upper roller shaft 30.
[0031] The above solution involves erecting an I-beam hoisting frame or directly using I-beams fixed in the green building. During hoisting, the open end of the I-beam must be bolted through and locked. During hoisting, the upper limit roller 31 is placed above the I-beam, and the two sets of middle limit rollers 22 are placed on both sides of the middle of the I-beam. At this time, the two sets of hoisting protective plates 1 are aligned on both sides of the upper limit roller 31 and the middle limit roller 22. The upper roller shaft 30 is then passed through the upper roller through hole 12, the middle roller plate through hole 23, and the upper limit roller 31. Next, the middle roller limit insert 21 at one end of the two sets of middle roller plates 20 is aligned with the middle roller insert 11 and the middle limit roller 22, and the middle roller plate through hole 23 is fitted on the outside of the upper roller shaft 30. Finally, the limit nuts 32 are screwed on both sides of the upper roller shaft 30 to complete the installation of the hoisting protective components. In this way, the hoisting rope is passed through the hoisting through hole 13 to achieve the effect of upper limit hoisting protection.
[0032] Reference Figure 7 The fall arrestor housing 5 includes a fall arrestor housing 50. A hoisting hole seat 51 is fixedly installed on the upper outer side of the fall arrestor housing 50. A rotating sleeve limiting groove 52 is opened through the upper interior of the fall arrestor housing 50. A ratchet triangular block 53 is fixedly installed on one side inside the fall arrestor housing 50. A rope threading hole 54 is opened through the middle of the lower part of the fall arrestor housing 50.
[0033] Reference Figure 8 The slider adjustment frame 6 includes an adjustment frame limiting frame 60. An adjustment screw 61 is threaded through the upper part of the adjustment frame limiting frame 60. A hexagonal extension rod 62 is fixedly installed at one end of the upper part of the adjustment screw 61. A slider 63 is slidably limited and slidably installed on the upper inner side of the adjustment frame limiting frame 60. A shaft adapter groove 64 is opened through the slider 63. A spring-loaded elastic element 65 is fixedly installed between the lower inner side of the adjustment frame limiting frame 60 and the lower part of the slider 63.
[0034] The above solution involves adding a fall arrestor between the ropes, or using a separate hoisting protection mechanism to suspend the fall arrestor. Under slow pulling conditions, the fall arrestor will not lock. When falling, the rope will quickly pull down the double ratchet winding rope roller 9 and the slider 63 via the intermediate rotating shaft 8, causing the double ratchet winding rope roller 9 to be locked by the ratchet triangular locking block 53. This achieves the fall arrest effect. Furthermore, by alternately rotating the two sets of adjusting rotating sleeves 7, the hexagonal extension rod 62, which slides inside the hexagonal deep groove 73, drives the adjusting screw 61 to rotate. This allows adjustment of the length of the adjusting screw 61 screwed into the adjusting frame limit frame 60, thereby squeezing the slider 63 to restrict its position. This allows for rapid adjustment of the distance between the double ratchet winding rope roller 9 and the ratchet triangular locking block 53, thus quickly adjusting the fall arrest trigger stroke.
[0035] Reference Figure 9 The adjusting rotating sleeve 7 includes a rotating sleeve body 70. A hexagonal shallow groove 71 is opened through the upper part of the rotating sleeve body 70. A transition limiting ring 72 is fixedly installed on the upper outer side of the rotating sleeve body 70. A hexagonal deep groove 73 is opened inside the lower part of the rotating sleeve body 70.
[0036] The working principle of this utility model is as follows: During use, an I-beam hoisting frame is erected, or I-beams fixed in green buildings are directly used. During hoisting, the open end of the I-beam must be bolted through and locked. The upper limit roller 31 is placed above the I-beam, and two sets of middle limit rollers 22 are placed on either side of the middle of the I-beam. The two sets of hoisting protective plates 1 are aligned with the upper limit roller 31 and the middle limit roller 22. The upper roller shaft 30 passes through the upper roller through hole 12, the middle roller plate through hole 23, and the upper limit roller 31. Then, the middle roller limit insert 21 at one end of the two sets of middle roller plates 20 is aligned with the middle roller insert hole 11 and the inside of the middle limit roller 22, and the middle roller plate through hole 23 is fitted onto the outside of the upper roller shaft 30. Finally, the limit nuts 32 are screwed onto both sides of the upper roller shaft 30 to complete the installation of the hoisting protective components. This completes the installation of the hoisting protective components. The upper limit of the lifting protection can be achieved by using a hoisting rope that runs through the 13-section rope. At the same time, by adding a fall arrestor between the ropes, or by using a separate set of hoisting protection mechanisms to install the fall arrestor, the fall arrestor will not lock under slow pulling conditions. When falling, the rope will quickly pull down the double ratchet winding rope roller 9 and the slider 63 through the intermediate rotating shaft 8, so that the double ratchet winding rope roller 9 is locked by the ratchet triangular block 53. This achieves the fall protection effect. By alternately rotating the two sets of adjusting rotating sleeves 7, the hexagonal extension rod 62, which slides inside the hexagonal deep groove 73, drives the adjusting screw 61 to rotate. This allows the length of the adjusting screw 61 screwed into the adjusting frame limit frame 60 to compress the slider 63 and restrict its position. This allows the distance between the double ratchet winding rope roller 9 and the ratchet triangular block 53 to be adjusted quickly, thus quickly adjusting the fall protection trigger stroke.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
