Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, and in particular to an adjustment mechanism for load-bearing beams. Background Technology

[0002] As a core piece of equipment for the vertical transportation of materials and personnel in high-rise building construction, the installation efficiency of traction construction hoists directly affects project progress and construction costs. The load-bearing beam is the core load-bearing component supporting the traction machine, counterweight, and cage; its fixing must ensure structural strength and stability. After installation, the load-bearing beam needs to be adjusted for levelness and verticality of the components mounted above it to prevent uneven stress and equipment vibration caused by tilting. The position of the load-bearing beam within the hoistway needs to be adjusted according to construction requirements to ensure positional accuracy with the guide rails, counterweight, and other components.

[0003] In some existing construction projects, load-bearing beams are hoisted using hoists or winches. This requires dismantling the upper components of the load-bearing beams first, then hoisting them to the target positions, and finally reinstalling them after hoisting. Afterward, the positioning accuracy and levelness of the load-bearing beams are adjusted manually, which consumes a lot of time, and the frequent disassembly and reassembly affect the operating accuracy of the equipment. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an adjustment mechanism for load-bearing beams. When the load-bearing beam is used in conjunction with an automatically lifting climbing frame, the position of the load-bearing beam can be adjusted to prevent it from tipping over.

[0005] Therefore, the technical solution of this utility model is: an adjustment mechanism for a load-bearing beam, comprising two sets of adjustment components fixed below the same load-bearing beam, the two sets of adjustment components having a 180° phase difference in the vertical direction and a 90° phase difference in the horizontal direction; the adjustment components include a first base, a second base, and an adjustment wheel set, the adjustment wheel set being located between the first base and the second base; the first base and the second base are provided with mutually perpendicular slide tracks, the adjustment wheel set including a mounting plate, a set of rollers mounted on each side of the mounting plate, the rollers on both sides being mutually perpendicular and slidably mounted in the slide tracks on both sides; the first base is provided with a limiting baffle on its side, the limiting baffle is provided with a limiting groove parallel to the slide track, and limiting protrusions extend from the two opposite sides of the mounting plate and are placed in the limiting groove.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: a first mounting seat is provided on one side of the mounting plate, a first rotating shaft is rotatably mounted on the first mounting seat, and first rollers are fixed at both ends of the first rotating shaft; a second mounting seat is provided on the other side of the mounting plate, a second rotating shaft is rotatably mounted on the second mounting seat, and second rollers are fixed at both ends of the second rotating shaft, and the second rotating shaft is perpendicular to the first rotating shaft.

The first base of the first adjustment component is arranged along the X-axis and fixed under the load-bearing beams distributed along the X-axis. The second base of the first adjustment component is arranged along the Y-axis. The second base of the second adjustment component is arranged along the X-axis and fixed under the load-bearing beams distributed along the X-axis. The first base of the second adjustment component is arranged along the Y-axis.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the load-bearing beam is installed on two support beams through a first adjustment component and a second adjustment component, and the load-bearing beam moves relative to the support beams on the X-axis and Y-axis through the adjustment components.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting groove of the upper limit baffle of the first adjustment component and the second adjustment component, and the slide rails on the first base and the second base, limit the movement of the load-bearing beam on the X-axis and Y-axis.

[0010] This utility model is used in conjunction with a climbing frame with an automatic lifting function. The climbing frame climbs within the shaft based on the climbing formwork principle. The load-bearing beams are mounted on the support beams of the climbing frame via adjustment components and are moved upwards by the climbing frame. The two load-bearing beams and two support beams are arranged in a grid pattern, with an adjustment component at each intersection point to facilitate movement of the load-bearing beams in the X and Y axis directions.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the load-bearing beam is installed on the support beam through adjustment components in different positions, and the position of the load-bearing beam on the X and Y axes can be adjusted by rollers and slides in different orientations, thereby ensuring the positional accuracy of the load-bearing beam, the force is balanced, and the overturning problem is avoided during the lifting process.

[0022] See attached diagram. This embodiment uses an adjustment mechanism for a load-bearing beam, including an adjustment assembly 1.

A first rotating shaft 133 is rotatably mounted on the first mounting seat 132. First rollers 134 are fixed at both ends of the first rotating shaft 133 and roll within the first slide rail 14. A second mounting seat 135 is provided on the other side of the mounting plate 131. A second rotating shaft 136 is rotatably mounted on the second mounting seat 135 and is perpendicular to the first rotating shaft 133. Second rollers 137 are fixed at both ends of the second rotating shaft 136 and roll within the second slide rail 15.

[0023] The first base 11 has a limiting baffle 16 on its side, and a limiting groove 161 parallel to the slide is provided on the limiting baffle 16. The two opposite sides of the mounting plate 131 extend into limiting protrusions 138, which are placed in the limiting groove 161.

[0024] Two sets of adjusting components 1, namely a first adjusting component 2 and a second adjusting component 3, are fixed below the same load-bearing beam 4. The first adjusting component 2 and the second adjusting component 3 have a 180° phase difference in the vertical direction and a 90° phase difference in the horizontal direction. Specifically, the first base of the first adjusting component 2 is positioned along the X-axis and fixed below the load-bearing beam 4, which is distributed along the X-axis; the second base of the first adjusting component 2 is positioned along the Y-axis and fixedly connected to the support beam.
