Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, specifically to a stacked beam telescopic structure for a construction hoist. Background Technology

[0002] With the acceleration of urbanization and the increasing number of high-rise and super high-rise buildings, construction hoists (also known as construction elevators) have become indispensable vertical transportation equipment on construction sites, undertaking the task of efficiently transporting personnel and materials. Construction hoists are usually installed in the elevator shaft or attached to the outside of the wall of a building, and their frame (guide rail frame) needs to be continuously heightened as the building rises. The superimposed beam (top beam), as a key load-bearing structure at the top of the hoist, not only bears the load of the cage, counterweight, and transmission system, but also relates to the stability and safety of the entire machine.

[0003] Traditional construction hoist truss beams are mostly fixed-length, one-piece structures, which have the following prominent problems: Transportation and hoisting are difficult: the fixed-length beams take up a lot of space during transportation and are inconvenient to load and unload; during on-site installation, they often need to be hoisted at an angle to the reserved opening, which is complicated and poses a high safety risk.

[0004] Poor adaptability: The shaft dimensions and wall spacing vary between different building projects, and the fixed-length stacked beams are difficult to adapt flexibly, resulting in frequent on-site cutting, welding or padding adjustments, which is time-consuming, labor-intensive, and prone to safety hazards.

[0005] Low installation efficiency: When the elevator needs to be upgraded with the increase of floors, the disassembly and adjustment process of traditional stacked beams is cumbersome, which seriously affects the construction progress. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a telescopic beam structure for a construction hoist, characterized by high structural strength and convenient telescopic adjustment. It enables rapid and reliable adjustment of the beam length to adapt to different construction scenarios while ensuring structural safety and stability.

[0007] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A telescopic structure for a construction hoist includes a pair of long beams, with several supporting angle steels between the two long beams. Supporting ear plates are provided at both ends of the supporting angle steels and the long beams. Short beams that are inserted into the long beams are provided on both sides of the long beams. Several pins are provided between the short beams and the long beams to limit the telescopic movement of the short beams. Connecting angle steels are provided on one or both sides of the short beams. Connecting plates that are welded and fixed to the short beams are provided between the connecting angle steels and the short beams.

[0008] Preferably, both the short beams and the long beams are made of "C" shaped steel.

[0009] Preferably, the short beam is provided with several telescopic limiting plates II that are inserted into the pin shaft at its side end, and the long beam is provided with several telescopic limiting plates I that are inserted into the pin shaft at its side end.

[0010] Preferably, the sides of the supporting ear plates are provided with inner connecting ear plates that are staggered with the supporting ear plates and welded and fixed to the long beam.

[0011] Preferably, the outer end of the long beam is provided with a pair of mirror-symmetrically distributed outer connecting lugs that are welded and fixed to the long beam.

[0012] Preferably, the supporting ear plate is welded and fixed to the long beam, and the supporting ear plate is connected and fixed to the supporting angle steel by bolt and nut structure.

[0013] Preferably, the connecting angle steel and the connecting plate are connected and fixed by bolts and nuts.

[0014] This invention can achieve the following effects: This invention provides a telescopic structure for a stacked beam of a construction hoist, which, compared with existing technologies, features high structural strength and convenient telescopic adjustment. It enables rapid and reliable adjustment of the stacked beam length to adapt to different construction scenarios while ensuring the safety and stability of the structure.

[0015] By combining a long beam with short beams, the overall length of the beams can be adjusted. The long beam serves as the main body, while the short beams are inserted into it like drawers and fixed in different positions by pins, thus changing the total length of the entire stacked beam. This makes the equipment easier to transport and allows for adjustments based on the actual spacing of the guide frames, improving the equipment's versatility and adaptability.

[0016] Convenient transportation and storage: The shrinkage greatly reduces the need for transport vehicles and storage space, thus lowering logistics costs.

[0017] High adaptability: The length of the stacked beams can be flexibly adjusted according to the guide frame spacing of different construction sites and different models of hoists, which improves the versatility of the product.

[0018] Stable structure: The design of C-shaped steel nesting, multi-point locking of pin shafts, and various reinforcing ear plates ensures the structural strength and stability after expansion and contraction.

[0019] Modularization and standardization: Each component (such as ear plate and angle steel) adopts a standardized design, which facilitates mass production and rapid on-site assembly. Attached Figure Description

[0027] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0028] Example: Figure 1-6 As shown, a telescopic structure of a construction hoist's stacked beam includes a pair of long beams 5. The outer ends of the long beams 5 are provided with a pair of mirror-symmetrically distributed outer connecting lugs 6 welded and fixed to the long beams 5. Several supporting angle steels 3 are provided between the two long beams 5. Supporting lugs 7 are provided at both ends of the supporting angle steels 3 and between them and the long beams 5. The supporting lugs 7 are bolted and fixed to the supporting angle steels 3, and welded and fixed to the long beams 5. On the sides of each supporting lug 7 are inner connecting lugs 8, staggered and welded and fixed to the long beams 5. Short beams 1 are provided on both sides of the long beams 5, interlocking with them. Both the short beams 1 and the long beams 5 are made of "C"-shaped steel. Two pins 4 are provided between the short beams 1 and the long beams 5 to limit the telescopic movement of the short beams 1. Two telescopic limiting plates II 11 are provided on the side ends of the short beams 1, interlocking with the pins 4. Two telescopic limiting plates I 9 are provided on the side ends of the long beams 5, interlocking with the pins 4. One or both short beams 1 are provided with connecting angle steel 2. A connecting plate 10 is provided between the connecting angle steel 2 and the short beam 1 and is welded and fixed to the short beam 1. The connecting angle steel 2 and the connecting plate 10 are connected and fixed by bolt and nut structure.

[0029] Shrinkage state (transportation / storage): Short beam 1 is completely shrunken inside long beam 5. At this time, the length of the entire stacked beam is the shortest, which facilitates transportation and storage.

[0030] Length adjustment (on-site installation): According to the actual spacing of the construction hoist guide frame, pull the short beam 1 on one or both sides out from the long beam 5.

[0031] When the hole of the telescopic limiting plate II 11 on the short beam aligns with a hole of the telescopic limiting plate I 9 on the long beam, the stretching stops.

[0032] Position locking: Insert pins 4 simultaneously into the aligned holes of telescopic limiting plates I and II. As described, two pins 4 are provided on each side for locking, ensuring reliable connection and torsional resistance, and preventing loosening or slippage during use.

[0033] Device connection: Fixed end: The entire stacked beam assembly is bolted to the fixed structure of the elevator by connecting the outermost ear plate 6 at the outermost end of the long beam.

[0034] Moving end: The stacked beam is fixed to the guide frame of the elevator or the moving part that needs to be connected by bolts through the connecting angle steel 2 at the end of the short beam.

[0035] In summary, the telescopic beam structure of this construction hoist features high structural strength and convenient telescopic adjustment. It enables rapid and reliable adjustment of the telescopic beam length to adapt to different construction scenarios while ensuring structural safety and stability.

[0036] C-shaped steel nested expansion: Utilizing the natural nesting characteristics of "C"-shaped steel, the beam can be smoothly expanded and contracted, balancing strength and lightweight.

[0037] Double pin multi-point locking: Through the telescopic limit plate and double pin design, the beam can be stably locked at any adjusted length, avoiding shaking or sliding during use.

[0038] Modular connection: A hybrid connection method of welding and bolts is widely used, which not only ensures the strength of key parts, but also facilitates rapid on-site assembly and subsequent maintenance.
