Description

Technical Field

[0001] This utility model relates to the field of construction equipment, and in particular to a climbing scaffolding mechanism with safety protection and temporary avoidance functions. Background Technology

[0002] Climbing scaffolds are widely used for construction protection in various types of high-rise and super high-rise buildings, as well as tall buildings with uniform shapes. They are particularly suitable for construction of complex shapes such as cast-in-place shear walls, frames, curved balconies, and cantilever slabs. During use, multiple floors are erected at once, and the scaffold can be raised one floor at a time as construction progresses, greatly improving construction efficiency. Multiple attachments to the building's exterior walls and multiple levels of protection ensure that workers are always within the scaffold's protective range, effectively preventing falling objects and falls. However, the construction process requires a large number of workers to stand on the scaffold, and a significant amount of building materials and tools are placed on the scaffold platforms, greatly increasing the scaffold's weight. There is also the risk of rapid descent, placing high demands on the safety of the support and lifting mechanisms. Furthermore, tower cranes are usually installed on the outside of the climbing scaffold for material transport, and the horizontal supports of these cranes need to be fixedly connected to the building structure. During the lifting or lowering of the scaffold, it may be obstructed by these horizontal supports, requiring disassembly and reassembly of the obstructing parts, making the operation process relatively complicated. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a climbing frame mechanism with safety protection and temporary avoidance functions.

[0004] The technical solution of this utility model is: a climbing scaffold mechanism with safety protection and temporary avoidance functions, comprising several outer bearing plates arranged horizontally on the upper and lower layers of the column frame, a right-angle bracket provided on the outer side of the building, a seat plate provided on the short right-angle side of the right-angle bracket, the seat plate being fixedly connected to the building wall, a slide rail provided on the inner side of the column frame, the slide rail being slidably connected to the outer end of the right-angle bracket, and a lifting assembly provided between the upper part of the building and the column frame; the inner side of the slide rail is provided with equal spacing along its length. There are several baffles, which are welded and fixed to the surface of the slide rail. A gear is rotatably connected to the outer end of the right-angle bracket via a horizontal shaft. The gear is close to the inner side of the slide rail. The gear includes circumferentially distributed limiting teeth, counterweight teeth, and shifting teeth. The end face of the shifting teeth is provided with a hook that can bend upwards and correspond to the position of the baffle. The hook is similar to the function of a ratchet. The bottom surface of the hook is a pressing slope. A limiting plate corresponding to the position of the counterweight teeth is provided between the outer ends of the two rods of the right-angle bracket. The limiting plate can block the upward rotating counterweight teeth.

[0005] Preferably, the outer support plate is formed by connecting several modular plates, wherein two adjacent modular plates are connected to the outer support plate by a hinge, and these two modular plates can be flipped upwards, and a locking component is provided between the two adjacent modular plates.

[0006] Preferably, the locking component includes a sleeve provided on the edge of the module plate, and a pin is inserted between the corresponding sleeves on the two module plates. When the corresponding sleeves on both sides are in a horizontal state, they are coaxially corresponding.

[0007] Preferably, one end of the pin is provided with a limiting head, and the other end is connected to a limiting nut by a thread. Both the limiting head and the limiting nut are provided with a certain distance from the surface of the outer bearing plate.

[0008] Preferably, several protective mesh panels are modularly connected between the outer surfaces of the outer bearing plate, and the edges of the protective mesh panels are square frame supports, which facilitates the fixed connection between them.

[0009] Preferably, the lifting component includes a chain winch connected to the building body via a tripod body. The tripod body has several support rods densely arranged inside, forming several triangular support structures. The lower end of the chain of the chain winch is hooked to the lower part of the column frame via a hook.

A hook is attached to the hanging plate, and a load-bearing sensor is provided on the hook to monitor the change of the self-weight of the climbing frame.

[0011] Preferably, the outer end of the right-angle bracket is symmetrically provided with two L-shaped seats, the L-shaped seats are fixedly connected to the outer end face of the right-angle bracket, and the inner side of the L-shaped seats slides against the side of the slide rail.

[0012] The beneficial technical effects of this utility model are:

[0013] (1) This utility model installs a limiting plate and a shift gear inside the right-angle bracket. The limiting plate and the shift gear are combined with the baffle in the slide rail of the climbing frame to form a safety protection mechanism. When the climbing frame is lifted or slowly descended, it can pass through the shift gear normally. When the climbing frame descends rapidly, the shift gear cannot be reset and is locked between the baffle and the limiting plate, thus achieving safety protection for the climbing frame and avoiding a safety accident of rapid fall.

[0014] (2) The two module plates in the bearing plate of this utility model can be lifted up to allow the horizontal support of the tower crane to pass, and can be locked in a horizontal bearing state by sleeve and pin, which is convenient to operate and simplifies the operation process.

[0023] Example 1, see appendix Figure 1-6A climbing scaffold mechanism with safety protection and temporary avoidance functions includes several outer bearing plates 02 arranged on the upper and lower layers of a column frame 01. A right-angle bracket 03 is provided on the outer side of the building body 91, and a slide rail 11 is provided on the inner side of the column frame 01. Two support rollers are symmetrically provided at the outer ends of the right-angle bracket 03. The slide rail is slidably connected to the support rollers on the right-angle bracket. A lifting assembly is provided between the upper part of the building body 91 and the column frame 01. Several baffles 12 are evenly spaced along the length of the inner side of the slide rail 11. These baffles are connected to the slide rail... The inner side of the rail is vertically welded and fixed. A shift gear 04 is rotatably connected to the outer end of the right-angle bracket 03 via a horizontal shaft 33. The shift gear includes a circumferentially distributed limiting tooth 41, a counterweight tooth 42, and a shift tooth 43. The outer end of the limiting tooth is provided with a support plane. When the support plane is in a horizontal state, it can support the bottom surface of the baffle 12. The end face of the shift tooth 43 is provided with a hook 44 that can bend upwards and correspond to the position of the baffle 12. The bottom surface of the hook is a top-pressing slope. A limiting plate 31 corresponding to the position of the counterweight tooth 42 is provided between the outer ends of the two rods of the right-angle bracket 03.

[0024] Several protective mesh panels 61 are modularly connected between the outer surfaces of the outer bearing plate 02. The protective mesh panels improve the safety of workers working on the outer bearing plate 02 and can avoid the safety risks of building materials or tools falling.

[0025] The lifting assembly includes a chain winch 72 connected to the building body 91 via a tripod 71. The lower end of the chain 74 of the chain winch is hooked to the lower part of the column frame 01 via a hook 73. The winch lifts or lowers the climbing frame body via the chain 74. The upper tripod 71 provides sturdy support for the winch. The lower part of the column frame 01 is provided with a reinforcing plate 81. A mounting plate 82 is hinged to the middle of the outer side of the reinforcing plate 81. The hook 73 is hooked to the mounting plate 82. The hinged mounting plate 82 has a certain amount of room for movement, which can form a certain amount of assembly redundancy and prevent mismatch in assembly position or jamming.

[0026] Two L-shaped seats 32 are symmetrically arranged at the outer end of the right-angle bracket 03. The inner side of the L-shaped seats slides against the side of the slide rail 11. The two L-shaped seats 32 play an auxiliary support role and improve the stability of the slide rail.

[0027] The working process and principle of this embodiment are as follows:

[0028] When the lifting component drives the climbing frame mechanism to lift upward, the baffle 12 on the inner side of the slide rail 11 contacts the top pressing inclined surface of the hook 44 on the end face of the tooth 43. The tooth 43 is pushed open by the top pressing inclined surface, and the tooth 04 will not affect the normal lifting of the climbing frame mechanism.

[0029] When the lifting component drives the climbing frame mechanism to descend slowly, the baffle 12 on the inner side of the slide rail 11 contacts the upper surface of the hook 44 on the end face of the pawl 43. The pawl 43 is slowly pushed open, and after the upper limiting tooth 41 rotates inward at a certain angle, it will automatically rotate outward to reset under the action of the counterweight tooth 42. The pawl 04 will not affect the normal slow descent of the climbing frame mechanism.

[0030] When the climbing frame mechanism descends rapidly due to an accident, the baffle 12 on the inner side of the slide rail 11 rapidly presses against the hook 44 on the end face of the pawl 43, and the pawl 43 is quickly pushed open. The upper limiting tooth 41 rotates rapidly inward and is pressed by the baffle 12 when it cannot be reset by the counterweight tooth 42. At the same time, the counterweight tooth 42 rotates upward and supports the bottom surface of the limiting plate 31. At this time, the pawl gear 04 is locked between the slide rail 11 and the right-angle bracket 03, and is in a locked state, which can realize the safety protection of the climbing frame and prevent the safety accident of rapid fall.

[0031] Example 2, see appendix Figure 3 This embodiment is basically the same as Embodiment 1, except that: the outer support plate 02 is formed by connecting several modular plates 21. Two adjacent modular plates are connected to the outer support plate by hinge. Both of these modular plates 21 can be flipped up to form a vertically penetrating space on the outer support plate 02. A locking component is provided between two adjacent modular plates 21. The locking component includes a sleeve 51 provided on the edge of the modular plate. A pin 52 is inserted between the corresponding sleeves on the two modular plates 21. After the pin 52 is inserted between the sleeves 51 on the two modular plates, the two are locked in a horizontal support state. One end of the pin is provided with a limiting head 53, and the other end is connected to a limiting nut 54 by a thread. The limiting head and the limiting nut 54 are combined to form an axial limiting structure to prevent the pin 52 from axially moving and slipping due to the vibration of the climbing frame.

[0032] When the climbing scaffold ascends or descends over the horizontal support of the tower crane, the pin 52 between the two module plates is pulled out to release the locking of the two module plates. Then, the two module plates 21 are lifted up to form a passage space. The protective net at this passage space can be left uninstalled or removed. At this time, the climbing scaffold passes smoothly over the horizontal support. Then, the sleeve 51 and the pin 52 are used to relock the two to a horizontal load-bearing state, completing the operation process.
