[0026] Most of the existing anti-fall sheds adopt a fixed structure. The anti-fall shed is directly set up on the construction ground. This type of anti-fall shed occupies a large area, which affects the ground construction. If the anti-fall shed is set up on a building, it will affect the vertical transportation of the building when lifting materials above the building.
[0027] The utility model proposes a cantilever folding construction protection device, including a support plate 10, a drum 20, a curved arm 30, a protection net 40 and a driving mechanism 50. The number of the support plates 10 is two, and the two support plates 10 are arranged at intervals. Each support plate 10 is connected to a building 80, and each support plate 10 extends in a direction away from the building 80; the drum 20 is rotatably connected between the two support plates 10; one end of the curved arm 30 is connected to a support plate 10, and the other end of the curved arm 30 is connected to the shed. The beam 60, the shed beam 60 and the drum 20 are arranged side by side and at intervals, the curved arm 30 can be folded or unfolded in a direction close to or away from the building 80, and an elastic member 31 is provided on the curved arm 30, the elastic member 31 is in a compressed state and can drive the curved arm 30 to unfold; the protective net 40 is connected between the curved arm 30 and the shed beam 60; the driving mechanism 50 is connected to the drum 20, and the driving mechanism 50 is used to drive the drum 20 to rotate so as to wind the protective net 40 around the drum 20 or to open the protective net 40 from the drum 20.
[0028] See also Figure 1 and Figure 2The reel 20 extends in the left-right direction, and the left and right ends of the reel 20 are respectively connected to the two support plates 10. The canopy beam 60 extends in the left-right direction, and the canopy beam 60 and the reel 20 are spaced apart in the front-back direction. The reel 20 and the canopy beam 60 are respectively connected to the two ends of the protection net 40. When the driving mechanism 50 drives the reel 20 to rotate forward, the reel 20 winds the protection net 40 on the reel 20, and the protection net 40 drives the canopy beam 60 to move in the direction close to the reel 20, and drives the crank arm 30 to fold, so as to retract the protection net 40; when the driving mechanism 50 drives the reel 20 to rotate reversely, the protection net 40 wound on the reel 20 is separated from the reel 20, and the crank arm 30 is unfolded under the restoring force of the elastic member 31, and drives the canopy beam 60 to move in the direction away from the reel 20, so as to open the protection net 40.
[0029] The cantilever folding construction protection device proposed by the utility model is configured to install a support plate 10 on a building 80, install a drum 20 and a curved arm 30 on the support plate 10, support the shed beam 60 through the curved arm 30, so that the shed beam 60 and the drum 20 cooperate with each other to open or retract the protection net 40, and the curved arm 30 extends out of the building 80 to form a cantilever structure, so that the cantilever folding construction protection device can be directly installed on the lower building 80 without occupying space; by setting a driving structure to drive the drum 20 to rotate so as to wind the protection net 40 around the drum 20, the control is convenient, and when the protection net 40 is retracted, it can drive the shed beam 60 to move close to the drum 20, and the shed beam 60 drives the curved arm 30 to fold, thereby realizing the folding of the cantilever folding construction protection device, effectively reducing the occupied space of the cantilever folding construction protection device, and not affecting the vertical transportation of the building 80 when lifting materials.
[0030] In one embodiment, the driving mechanism 50 includes a tubular motor 51 and a reduction assembly 52, the reduction assembly 52 includes a worm and a worm wheel, the output shaft of the tubular motor 51 is connected to the worm, the worm and the worm wheel are meshed with each other, and the worm wheel is connected to the reel 20, and the tubular motor 51 is used to drive the worm to rotate, so as to drive the reel 20 to rotate through the worm wheel.
[0031] It can be understood that the tubular motor 51 has a compact tubular structure. The tubular motor 51 is installed close to the building 80, which can effectively reduce the space occupied by the cantilever folding construction protection device. The tubular motor 51 is used to drive the worm to rotate, and the rotation of the worm is transmitted to the worm wheel through meshing, and finally the reel 20 is driven to rotate through the worm wheel. By setting the reduction assembly 52 to reduce the output shaft of the tubular motor 51, the drive mechanism 50 has a larger torque, ensuring that the drive structure has sufficient driving force to drive the reel 20 to rotate, and drive the curved arm 30 to overcome the elastic force of the elastic member 31 through the protective net 40 and the shed beam 60 to fold.
[0032] In one embodiment, the tubular motor 51 is a manual tubular motor 51, which includes a handle, a drive shaft, a motor movement and an output shaft. The motor movement is connected to the output shaft, and the handle is connected to the output shaft through the drive shaft.
[0033] It can be explained that the motor movement can drive the output shaft to rotate when the power is on, and when the motor movement is powered off, the drive shaft is driven to rotate by manually rotating the handle to drive the output shaft to rotate, so that the protective net 40 can be controlled to be folded and opened in the power-off state, effectively improving the applicability of the cantilever folding construction protection device.
[0034] In one embodiment, the worm wheel is connected to the drum 20 via a spline. Further, the worm wheel is connected to the drum 20 via a four-plane spline structure, so that the torque on the worm wheel can be smoothly transmitted to the drum 20, ensuring that the driving structure effectively drives the drum 20 to rotate.
[0035] In one embodiment, there are two curved arms 30 , and the two curved arms 30 are connected to the two support plates 10 in a one-to-one correspondence, and the two curved arms 30 can be folded toward each other.
[0036] See also Figure 1 and Figure 2 The two curved arms 30 are arranged at intervals along the left-right direction and are respectively connected to the left and right sides of the canopy beam 60. The two curved arms 30 can be folded or unfolded synchronously, so that the two curved arms 30 provide a stable support for the canopy beam 60, and the folding and unfolding process of the protective net 40 is synchronous and stable. The two curved arms 30 can be folded toward each other when folded, so that the two curved arms 30 occupy a smaller space when folded.
[0037] In one embodiment, the cantilever folding construction protection device also includes a tie rod assembly 70, the tie rod assembly 70 includes a tie rod 71, a hinge seat 72 and an adjusting turnbuckle 73, the hinge seat 72 is installed on the building 80, and the hinge seat 72 is located above the support plate 10, the tie rod 71 is connected between the adjusting turnbuckle 73 and the shed beam 60, one end of the adjusting turnbuckle 73 is connected to the tie rod 71, and the other end of the adjusting turnbuckle 73 is hinged to the hinge seat 72.
[0038] See also Figure 3, the hinge seat 72 is located above the support plate 10, the adjustment turnbuckle 73 is hinged on the hinge seat 72, and the pull rod 71 is obliquely connected between the adjustment turnbuckle 73 and the shed beam 60. The pull rod 71 provides tension to the shed beam 60 to ensure that the protection net 40 has sufficient stability. When the protection net 40 is folded, the pull rod 71 and the adjustment turnbuckle 73 can rotate relative to the hinge seat 72, and the distance between the pull rod 71 and the hinge seat 72 can be adjusted by adjusting the length of the adjustment turnbuckle 73, ensuring that the pull rod assembly 70 is connected between the shed beam 60 and the building 80, ensuring that the cantilever folding construction protection device is folded smoothly. It can be explained that the hinge seat 72 of the pull rod assembly 70 is anchored and connected to the building 80.
[0039] In one embodiment, there are two tie rod assemblies 70 , the two hinge seats 72 of the two tie rod assemblies 70 are respectively located directly above the two support plates 10 , and the two tie rods 71 of the two tie rod assemblies 70 are respectively connected to the two ends of the canopy beam 60 .
[0040] It can be understood that the two tie rod assemblies 70 are respectively arranged corresponding to the two support plates 10, and the two hinged seats 72 in the two tie rod assemblies 70 are respectively arranged opposite to the two support plates 10. The two tie rod assemblies 70 provide effective support for the shed beam 60, ensuring that the left and right sides of the shed beam 60 are balanced in force, thereby further improving the stability of the protective net 40.
[0041] In one embodiment, the crank arm 30 is arranged to be tilted upward from the support plate 10 to the canopy beam 60. Figure 3 The curved arm 30 is tilted upward from the back to the front, which can prevent the protective objects on the protective net 40 from sliding outward. In one embodiment, the tilt angle of the curved arm 30 is 5°.
[0042] In one embodiment, each support plate 10 is connected to the building 80 via a base, and each base is anchored to the building 80 via an anchor bolt buried in the building 80 .
[0043] It can be understood that the base is arranged close to the building 80, and each base is provided with two anchor bolts, each anchor bolt is buried in the building 80 to firmly connect the base to the surface of the building 80. The support plate 10 is connected to the base by bolts, ensuring that the support plate 10 is firmly arranged outside the building 80 and facilitating the loading and unloading of the support plate 10. The reel 20 arranged between the two support plates 10 is arranged close to the building 80, so that the cantilever folding construction protection device occupies less space in the folded state.
[0044] In one embodiment, the protective net 40 includes a stainless steel rope net and a PVDF membrane fixed on the stainless steel rope net.
[0045] It can be understood that the stainless steel rope net has good corrosion resistance, weather resistance and high tensile strength, which provides the necessary strength and durability for the protective net 40. The PVDF membrane has good weather resistance, chemical resistance and UV resistance. The stainless steel rope net and the PVDF membrane cooperate with each other to make the protective net 40 have good structural strength and durability, ensuring that the protective net 40 can intercept the protective objects falling from the building and ensure the safety of the personnel and equipment under the protective net 40.
