Description

Technical Field

[0001] The present application relates to the field of building construction technology tools, and in particular to a hanging basket for the construction of a large-span special-shaped curved steel structure roof. Background Art

[0002] When constructing the exterior wall of a curved building through a hanging basket, considering the complex curvature and irregularity of the facade of the curved building, a flexible hanging method is required to ensure that the hanging basket can fit the surface of the exterior wall. Specifically, the height and position of the hanging basket can be changed by adjusting the hanging angle of the hanging basket, using adjustable slings or hydraulic systems to adapt to the different concave and convex changes of the curved wall. This ensures that the hanging basket remains stable during construction and minimizes the gap with the exterior wall, so that construction workers can more easily access the wall and perform delicate construction operations such as painting, cleaning or repair.

[0003] The existing Chinese patent application with application number 201710087617.5 discloses a hanging basket for the construction of bidirectional curved building exteriors. The device uses a lifting mechanism to pull the hanging basket to move up and down along the vertical skeleton of the steel structure, so that the hanging basket is attached to the curved wall surface, which is convenient for workers to construct. However, in this device, when the hanging basket is attached to the surface of the curved wall and tilts, since the tilt angle of the hanging basket is related to the curvature of the wall surface, the workers standing in the hanging basket will change their posture as the hanging basket tilts, causing them to be unable to maintain a normal standing state. At this time, the workers need to constantly adjust their body balance and may feel uncomfortable or tired, which affects the stability and safety of their work. In addition, the workers cannot maintain the best working posture in the tilted hanging basket, which not only increases the difficulty of operation, but also may affect the accuracy and efficiency of construction. Summary of the invention

[0004] The present application proposes a hanging basket for the construction of a large-span special-shaped curved steel structure roof, which allows the operator to maintain a normal standing position inside the inclined hanging basket body, reduces the instability and fatigue caused by the tilt, enhances the safety and stability of the entire operation process, reduces the occurrence of errors, and improves construction efficiency. It is used to solve the problem of reduced construction safety, stability and construction efficiency due to the inability of workers to stand normally when the hanging basket is attached to the curved building wall during the construction process.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a hanging basket for the construction of a large-span special-shaped curved steel structure roof, comprising a hanging basket body, and also comprising two protective plates symmetrically fixedly installed at both ends of the hanging basket body, a support shaft being rotatably connected between the two protective plates, a bottom plate being fixedly installed on the outside of the support shaft, two connecting columns being symmetrically fixedly installed at both ends of the bottom plate, an installation cavity being provided inside the protective plate, a cylinder body being slidably installed inside the installation cavity, an end of the connecting column away from the bottom plate being fixedly connected to the cylinder body, a piston being slidably installed inside the cylinder body, a piston rod being fixedly installed on one end of the piston, an end of the piston rod away from the piston air-tightly passing through the cylinder body, an adjusting rod being slidably connected inside the piston rod, a plurality of first through holes being provided on the outside of an end of the piston rod close to the piston, a second through hole being provided at the axis center of the piston, the first through hole and the second through hole being used to provide a flow channel for the hydraulic medium inside the cylinder body.

[0006] Furthermore, a connecting groove is provided on one side of the protective plate close to the bottom plate, which is slidably connected to the connecting column. The cylinder body, piston rod and adjusting rod are all arc-shaped, and the axis of the arc axis of the cylinder body, piston rod and adjusting rod coincides with the axis of the support shaft.

[0007] Furthermore, an adjustment groove connected to the installation cavity is opened inside the protective plate, a fixing ring is fixedly installed on the inner bottom end of the adjustment groove, the end of the piston rod away from the piston is fixedly connected to the fixing ring, a spring is fixedly installed on the top of the fixing ring, the end of the adjustment rod away from the piston slides through the fixing ring and the spring and is fixedly connected to the fixing plate, and the top of the spring is fixedly connected to the bottom wall of the fixing plate.

[0008] Furthermore, a limit plate is slidably installed on the inner top of the adjustment groove, and an adjustment column is rotatably installed on the top of the limit plate. The top of the adjustment column passes through the protective plate and is threadedly connected to the protective plate. An adjustment handle is fixedly installed on the top of the adjustment column, which is used for the operator to drive the adjustment column to rotate by turning the adjustment handle.

[0009] Furthermore, a mounting groove is opened inside one of the protective plates, and the end of the support shaft close to the mounting groove slides through the side wall of the protective plate and is fixedly connected to a worm gear. A worm that meshes with the worm gear is also rotatably installed inside the mounting groove, a rotating shaft is fixedly installed at one end of the worm, and a rotating handle is fixedly installed at the end of the rotating shaft away from the worm.

[0010] Furthermore, a movable groove is provided at the top of the protective plate to provide a running space for the turning handle, a clamping block is slidably connected to the top of the protective plate, two limit sliding blocks are symmetrically fixedly installed at the bottom of the clamping block, and two limit sliding grooves are provided at the top of the protective plate that are respectively connected to the limit sliding blocks in a limit sliding manner.

[0011] Furthermore, two groups of support rods are symmetrically fixedly installed on one side of the hanging basket body close to the adjustment column, and a guide wheel is rotatably installed on one end of the support rod away from the hanging basket body.

[0012] The beneficial effects of the present invention are as follows:

[0013] The present application provides a hanging basket for the construction of a large-span special-shaped curved steel structure roof. The flow rate of the hydraulic oil is controlled by controlling the position of the adjusting rod inside the piston rod, and then the rotation speed of the base plate is controlled when the operator drives the worm, worm wheel and base plate to rotate through the turning handle, so as to avoid large swings due to the large number of people bearing the weight on the surface of the base plate, so that the operator can adjust his or her standing state more stably and slowly, and reduce the physical burden caused by the sharp swing of the base plate. By adjusting the base plate, the operator can still maintain a normal standing state inside the tilted hanging basket body, thereby ensuring that the operator will not cause discomfort due to body imbalance during the operation, reducing the instability and fatigue caused by the tilt, and achieving the effect of enhancing the safety and stability of the entire operation process. The stable standing posture also enables the operator to operate more accurately, reduce the occurrence of errors, and improve construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For example, see Figures 1 to 6 A hanging basket for construction of a large-span special-shaped curved steel structure roof comprises a hanging basket body 1, two sets of support rods 27 are symmetrically fixedly installed on one side of the hanging basket body 1, and a guide wheel 28 is rotatably installed on one end of the support rod 27 away from the hanging basket body 1. When it is necessary to construct the outer wall of the curved building, the guide wheel 28 is made to lean against the vertical skeleton of the building steel structure through the hanging device to realize the rail-based lifting of the hanging basket body 1. It also comprises two protective plates 2 symmetrically fixedly installed at both ends of the hanging basket body 1, a support shaft 3 is rotatably connected between the two protective plates 2, a bottom plate 4 is fixedly installed on the outside of the support shaft 3, and two connecting columns 5 are symmetrically fixedly installed on both ends of the bottom plate 4, an installation cavity 6 is opened inside the protective plate 2, a cylinder body 7 is slidably installed inside the installation cavity 6, and a hydraulic medium is filled inside the cylinder body 7. In this embodiment, the hydraulic medium adopts hydraulic oil.

[0024] The end of the connecting column 5 away from the bottom plate 4 is fixedly connected to the cylinder body 7, and a connecting groove 51 slidably connected to the connecting column 5 is provided on the side of the protective plate 2 close to the bottom plate 4. The connecting groove 51 is a sliding passage space for the connecting column 5. A piston 8 is slidably installed inside the cylinder body 7, and a piston rod 9 is fixedly installed at one end of the piston 8. The end of the piston rod 9 away from the piston 8 airtightly passes through the cylinder body 7, and an adjusting rod 10 is slidably connected inside the piston rod 9. The cylinder body 7, the piston rod 9 and the adjusting rod 10 are all arranged in an arc shape, and the axis of the arc axis of the cylinder body 7, the piston rod 9 and the adjusting rod 10 coincides with the axis of the support shaft 3. A plurality of groups of first through holes 11 are provided on the outer side of the end of the piston rod 9 close to the piston 8, and the adjusting rod 10 is used to block each group of first through holes 11. A second through hole 12 is provided at the axis center of the piston 8. The operator needs to rotate the bottom plate 4 according to the inclination angle of the hanging basket body 1 to adjust the adjustment rod 10. When adjusting the standing state, first adjust the position of the control adjusting rod 10 inside the piston rod 9 to release the blockage of the first through hole 11 by the adjusting rod 10, and then partially connect the first through hole 11 with the second through hole 12. The hydraulic oil can flow inside the cylinder body 7 through the first through hole 11 and the second through hole 12, so that when the base plate 4 rotates, the cylinder body 7 can be driven to slide toward the piston rod 9 through the connecting column 5. Among them, the operator can adjust the position of the adjusting rod 10 according to the load-bearing condition of the surface of the base plate 4. When the surface of the base plate 4 bears a large number of people, the adjusting rod 10 is closer to the piston 8, and the first through hole 11 that can be connected to the second through hole 12 is relatively small, and the flow rate of the hydraulic oil is slower, avoiding the situation where a large swing occurs due to the large number of people bearing the surface of the base plate 4, so that the operator can adjust his own standing state more stably and slowly, with higher safety and stability.

[0025] For example 2, please refer to Figures 3 to 6On the basis of the first embodiment, the protective plate 2 is provided with an adjusting groove 13 connected with the mounting cavity 6, a fixing ring 14 is fixedly installed at the inner bottom end of the adjusting groove 13, the end of the piston rod 9 away from the piston 8 is fixedly connected with the fixing ring 14, a spring 15 is fixedly installed on the top of the fixing ring 14, the end of the adjusting rod 10 away from the piston 8 slides through the fixing ring 14 and the spring 15 and is fixedly connected with a fixing plate 16, the top of the spring 15 is fixedly connected with the bottom wall of the fixing plate 16, the elastic force of the spring 15 enables the fixing plate 16 to drive the adjusting rod 10 to slide upward, the inner top of the adjusting groove 13 is slidably installed with a limiting plate 17, and the top of the limiting plate 17 is rotatably installed There is an adjusting column 18, the top end of the adjusting column 18 passes through the protective plate 2 and is threadedly connected to the protective plate 2, and an adjusting handle 19 is fixedly installed on the top end of the adjusting column 18. When it is necessary to release the blockage of part of the first through hole 11 by sliding the adjusting rod 10, the operator can drive the adjusting column 18 to rotate by turning the adjusting handle 19, and when the adjusting column 18 rotates, it drives the limit plate 17 to move upward. After the limit of the limit plate 17 on the fixed plate 16 is released, under the action of the elastic force of the spring 15, the adjusting rod 10 can slide upward, thereby releasing the blockage of part of the first through hole 11 by the adjusting rod 10, so that the first through hole 11 can be connected with the second through hole 12 to provide flow space for the hydraulic oil.

[0026] For example 3, please refer to Figure 2 and Figure 3 On the basis of the first embodiment, a mounting groove 20 is provided inside one of the protective plates 2, and one end of the support shaft 3 close to the mounting groove 20 slides through the side wall of the protective plate 2 and is fixedly connected with a worm gear 21, and a worm 22 meshing with the worm gear 21 is also rotatably installed inside the mounting groove 20, and a rotating shaft 23 is fixedly installed at one end of the worm 22, and a rotating handle 24 is fixedly installed at the end of the rotating shaft 23 away from the worm 22, and a movable groove is provided on the top of the protective plate 2 to provide a running space for the rotating handle 24. When the operator needs to rotate the bottom plate 4 to adjust his own standing state, the operator can drive the worm 22 and When the rotating shaft 23 rotates and the worm 22 rotates, the worm wheel 21 is driven to rotate through the meshing transmission, and the worm wheel 21 drives the base plate 4 to rotate through the supporting shaft 3, thereby completing the adjustment of the base plate 4, and the top of the protective plate 2 is slidably connected with a clamping block 25, and two limit sliders are symmetrically fixedly installed on the bottom of the clamping block 25. The top of the protective plate 2 is provided with two limit sliding grooves 26 which are respectively connected to the limit sliding blocks for limit sliding. After the adjustment of the base plate 4 is completed by rotating the turning handle 24, the sliding clamping block 25 is used to limit the turning handle 24, thereby preventing the base plate 4 from shaking due to gravity, and further improving the safety and stability of the base plate 4.

[0027] Working principle:

[0028] When it is necessary to construct the outer wall of a curved building, the guide wheel 28 is placed against the vertical frame of the building's steel structure through the suspension device to achieve rail-based lifting of the hanging basket body 1. When the operator needs to adjust his standing state according to the inclination angle of the hanging basket body 1, the operator can rotate the adjusting handle 19 to drive the adjusting column 18 to rotate. When the adjusting column 18 rotates, it drives the limit plate 17 to move upward. After the limit plate 17 is released from the limit position of the fixed plate 16, the adjusting rod 10 can be adjusted under the action of the elastic force of the spring 15. The adjusting rod 10 slides upward to release the blockage of the first through hole 11, so that the first through hole 11 can be connected with the second through hole 12 to provide flow space for the hydraulic oil, and then the limit of the rotating handle 24 is released by the sliding block 25. The operator rotates the rotating handle 24 to drive the worm 22 and the rotating shaft 23 to rotate. When the worm 22 rotates, the worm wheel 21 rotates through the meshing transmission. The worm wheel 21 then drives the bottom plate 4 to rotate through the support shaft 3. When the bottom plate 4 rotates, it can drive the cylinder body 7 toward the active part through the connecting column 5. The piston rod 9 slides in the direction of the piston rod 9. At this time, the hydraulic oil inside the cylinder body 7 flows through the first through hole 11 and the second through hole 12. The flow rate of the hydraulic oil is controlled by controlling the position of the adjusting rod 10 inside the piston rod 9. The flow rate of the hydraulic oil determines the sliding speed of the cylinder body 7 in the hydraulic system, and then provides a buffering effect on the rotation of the base plate 4, which can effectively slow down the rotation speed of the base plate 4 and avoid the situation where the base plate 4 has a large number of surface load-bearing people and swings sharply, so that the operator can adjust his standing state more stably and slowly, and reduce the physical burden caused by the sharp swing of the base plate 4. By adjusting the base plate 4, the operator can still maintain a normal standing state inside the tilted hanging basket body 1, thereby ensuring that the operator will not cause discomfort due to body imbalance during the operation, reducing the instability and fatigue caused by the tilt, and enhancing the safety and stability of the entire operation process. The stable standing posture also enables the operator to operate more accurately, reduce the occurrence of errors, and improve construction efficiency.
