Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an adjustable heavy-load guide rail roller device and an assembled building. Background Art

[0002] With the development of prefabricated buildings, in order to expand the space of the box and meet the requirements of transportation conditions, a telescopic box is often provided on the fixed box, and the telescopic box is slidably connected to the fixed box through the structure of a guide rail slider.

[0003] In the prior art, guide rails and sliders are often installed and matched through rollers. A group of relative rollers clamp the guide rails to achieve the sliding and limiting of the slider. However, the position of the rollers cannot be adjusted after installation, and the spacing between the relatively arranged rollers is fixed, which is adapted to guide rails of specific sizes, thereby requiring high precision in the overall installation and manufacturing of the box. When the weight of the telescopic box is large and a larger guide rail needs to be replaced, the slider needs to be replaced simultaneously. In addition, when the guide rails or rollers are worn, the telescopic box is prone to displacement under the action of the load, affecting the sliding of the telescopic box and the stability of the overall structure.

[0038] like Figure 2-5 As shown, the adjustable heavy-duty guide rail roller device includes a square tube guide rail 3 and a plurality of roller mechanisms 4 arranged at intervals along the length direction of the square tube guide rail 3. The square tube guide rail 3 is installed on the telescopic box 2 for hanging and supporting the telescopic box 2. The roller mechanism 4 includes a fixed seat 42, a first roller assembly 43 and a second roller assembly 44 arranged opposite to each other, and an adjustment assembly. The fixed seat 42 is connected to the fixed box 1, and the first roller assembly 43, the second roller assembly 44 and the adjustment assembly are all arranged on the fixed seat 42. The square tube guide rail 3 is clamped between multiple groups of first roller assemblies 43 and second roller assemblies 44, as a cantilevered roller 431 guide rail module of the telescopic box 2. The first roller assembly 43 and the second roller assembly 44 are both connected to the adjustment assembly, and the spacing between the first roller assembly 43 and the second roller assembly 44 is adjusted by the adjustment assembly to match square tube guide rails 3 of different sizes. Furthermore, the horizontal heights of the first roller assembly 43 and the second roller assembly 44 can be synchronously adjusted by adjusting the assembly, so that the floor of the telescopic box 2 and the floor of the fixed box 1 are at the same horizontal height by driving the square tube guide rail 3 to adjust the horizontal height of the telescopic box 2. When the roller assembly or the square tube guide rail 3 is worn, the spacing between the first roller assembly 43 and the second roller assembly 44 can be fine-tuned so that the two roller assemblies are always effectively in contact with the square tube guide rail 3 and provide a certain clamping force to prevent the telescopic box 2 from being displaced downward due to the force of the load, and to prevent the telescopic box 2 from tilting downward after being extended.

[0039] like Figure 5As shown, the first roller assembly 43 and the second roller assembly 44 each include a bracket fixing plate 435, a roller 431 and a square bracket 432. The roller 431 is rotatably connected to the square bracket 432 through a rotating shaft 434, and a portion of the roller 431 is located inside the square bracket 432, and a portion of the roller 431 located outside the square is used to abut against the square tube guide rail 3. The square bracket 432 is slidably connected to the fixing seat 42 through the bracket fixing plate 435, so as to facilitate the position adjustment of the square bracket 432. The adjustment component is connected to the square bracket 432, and the position of the square bracket 432 is adjusted by the adjustment component, thereby adjusting the spacing between the rollers 431 of the first roller assembly 43 and the second roller assembly 44. Furthermore, a strip hole is provided on the bracket fixing plate 435, and the bracket fixing plate 435 is connected to the fixing seat 42 through a plurality of bolts sleeved in the strip hole. When installing the bracket fixing plate 435, first use the fixing bolts 45 to initially position the bracket fixing plate 435 on the fixing seat 42, insert the square tube guide rail 3 between the rollers 431 of the first roller assembly 43 and the second roller assembly 44, and adjust the spacing between the first roller assembly 43 and the second roller assembly 44 through the adjustment assembly until the upper and lower surfaces of the square tube guide rail 3 are tangent to the roller 431 surfaces of the first roller assembly 43 and the second roller assembly 44, and then tighten all the fixing bolts 45. When it is necessary to fine-tune the spacing between the first roller assembly 43 and the second roller assembly 44, first loosen the fixing bolts 45 on the roller assembly that needs to be adjusted, and then tighten the fixing bolts 45 after adjusting the spacing between the first roller assembly 43 and the second roller assembly 44 through the adjustment assembly.

The plurality of first adjustment bolts 411 are all threadedly connected to the first mounting plate, and the plurality of first adjustment bolts 411 are all abutted against the square bracket 432 of the first roller assembly 43; similarly, the plurality of second adjustment bolts 412 are all threadedly connected to the second mounting plate, and the plurality of second adjustment bolts 412 are all abutted against the square bracket 432 of the second roller assembly 44. By adjusting the plurality of first adjustment bolts 411 and the plurality of second adjustment bolts 412, the square bracket 432 is driven to move, thereby adjusting the distance between the two rollers 431, which has a simple structure and convenient adjustment. In addition, by synchronously adjusting the plurality of first adjusting bolts 411 and the plurality of second adjusting bolts 412, the square bracket 432 of the first roller assembly 43 and the second roller assembly 44 can be driven to synchronously move upward or downward, and the square tube guide rail 3 can synchronously move upward or downward with the square bracket 432 of the first roller assembly 43 and the second roller assembly 44, thereby realizing the overall upward or downward movement of the telescopic box, and adjusting the horizontal height of the telescopic box so that the floor of the telescopic box 2 and the floor of the fixed box 1 are at the same horizontal height.
