Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a building climbing frame. Background Art

[0002] At present, building climbing scaffolding is a kind of construction external scaffolding, which is mainly used in high-rise and multi-story civil and industrial buildings. The use of building climbing scaffolding can significantly improve construction efficiency, reduce the labor intensity of workers, reduce material consumption and reduce construction costs. When using building climbing scaffolding, it is necessary to install and operate it in accordance with regulations to ensure its stability and safety.

[0003] The prior art has a patent publication number of CN214364858U, which discloses a building climbing frame for construction, including a bracket, a lifting frame, a rack, a lifting chamber, a lifting ring, an anti-falling device, a pulley 1, a pulley 2, and a pulley 3. The lifting chamber can be easily raised and lowered by driving a steel wire rope around the pulley through a motor. The patent can prevent the lifting chamber from falling and protect the safety of construction workers.

[0004] However, the patent uses a steel wire rope to achieve the lifting of the lifting chamber. It is difficult to make the lifting chamber more stable only by pulling the steel wire rope, and the stability is poor.

[0005] The prior art discloses a building climbing frame with the authorization announcement number of CN219773534U. The patent relates to the field of building technology, specifically a building climbing frame for construction, including a base, a lifting device and a climbing basket.

A damping slide and a damping slide bar are arranged in the base, wherein the inflatable cushion is adapted to the bottom wall of the base and is provided with anti-slip silica to prevent slipping. A switch door is arranged on the front side of the climbing basket to facilitate workers to enter, and a safety lock is provided to prevent falling.

[0006] However, this patent realizes the lifting and lowering of the climbing frame by two threaded rods, and the single lifting method makes the lifting and lowering of the climbing frame relatively unstable. Utility Model Content

Through the arrangement of the lifting screw 51, the cable 14 and other structures, the cable 14 pulls the fixed frame 4 to move, so as to realize the lifting and lowering of the climbing frame 3, and the movement of the sliding block 50 is driven by the lifting screw 51 to synchronously realize the lifting and lowering of the climbing frame 3. The synchronous driving of the cable 14 and the lifting screw 51 makes the climbing frame 3 more stably lifted and lowered, thereby ensuring the stability of the lifting and lowering of the device.

[0032] like Figure 1-Figure 3 As shown, two slide grooves are provided on the support frame 2, and the sliding block 50 is slidably connected inside the slide grooves.

[0033] like Figure 1-Figure 3 As shown, a circular hole is opened on the support frame 2, and the rotating shaft 6 is rotatably installed inside the circular hole, and the driving bevel gear 54 and the driven bevel gear 53 are meshed.

Through the sliding of the telescopic block 9 and the shock absorption of the buffer spring 10, the climbing frame 3 drives the fixed plate 18 to fall more flexibly and stably, thereby avoiding damage to the climbing frame 3 caused by a large impact force and increasing the service life of the components.

[0041] like Figure 1-Figure 5 As shown, a buffer groove is provided on the fixed block 8, a part of the telescopic block 9 is slidably connected inside the buffer groove, and a buffer spring 10 is fixedly connected to the bottom of the buffer plate 11 and the top of the base 1.

[0042] The specific implementation principle of this embodiment is as follows: when the climbing frame 3 descends, the climbing frame 3 falls on the buffer plate 11, and the buffer plate 11 is squeezed to drive the telescopic block 9 to slide inside the buffer groove. Through the cooperation of the buffer spring 10, the impact force of the climbing frame 3 descending is weakened, thereby avoiding damage to the climbing frame 3 or personal injury caused by a large impact force.
