The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] In the description of this application, "multiple" means two or more.

[0035] In the description of this application, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them.

[0037] The following is for reference. Figures 1-9 This application describes a movable mechanism frame 100 and an assembly according to embodiments thereof.

[0038] The mobile support frame 100 according to an embodiment of this application includes a base 110, a support platform 120, and a truss 130 connecting the base 110 and the support platform 120. The truss 130 includes a horizontal truss 131 and a vertical truss 132 that are relatively perpendicular. The horizontal truss 131 and the vertical truss 132 can be assembled into a whole truss 130, for example, based on bolt ball joints 140. A support wheel 111 is provided below the base 110, allowing the entire mobile support frame 100 to move and change its position to correspond to different construction areas. The support platform 120 is quickly connected via supports 1311, and the truss 130 is a prefabricated structure. The support platform 120 is mounted on the horizontal truss 131, and the horizontal trusses 131 are spliced ​​to form a rectangle to define the support surface for mounting the support platform 120. Of course, the horizontal truss 131 can also be assembled into other shapes.

[0039] Understandably, the truss 130 comprises multiple interconnected members. During construction, trusses 130 of varying heights can be used to adapt to different construction conditions, thereby enabling the support platform 120 to support workers on top for construction. The assembly of the trusses 130 is cost-effective and allows for rapid manufacturing. Furthermore, the support platform 120 is positioned on a support surface. On one hand, the area of ​​the support surface formed by the multiple transverse trusses 131 is larger than that of a construction vehicle's operating platform. On the other hand, the truss 130 provides better support, allowing for a larger support platform 120 to accommodate more workers simultaneously.

[0040] Further reference Figures 1-7 We can understand the exemplary structure.

[0041] like Figure 1As shown, the mobile support frame 100 has supporting wheels 111 located under its base 110 at the four corners to drive the entire mobile support frame 100 to move. Specifically, the base 110 is a 4m x 6m frame beam welded from hot-rolled H-beams, for example, using 400x400 H-beams made of Q235B steel as the four beams of the frame beam. Of course, other profiles can also be used for welding and assembly of the frame beam, as long as they meet the various parameter requirements. The supporting wheels 111 are connected to the base 110 through a rotating mechanism to allow for 360-degree rotation, thereby ensuring that the mobile support frame 100 can move flexibly.

[0042] Hydraulic cylinders 112 are installed at the four corners of the base 110 on the side away from the supporting rudder wheel 111. One end of the hydraulic cylinder 112 is connected to the base 110, and the other end engages with the end of the longitudinal truss 132. The hydraulic cylinder 112 is located at the center of the end of the longitudinal truss 132. In this way, after the base 110 and the longitudinal truss 132 are assembled, the overall height of the movable support frame 100 can be adjusted by driving the hydraulic cylinders 112, thereby adapting to different construction conditions.

[0043] In detail, during the construction process, for some high-altitude construction areas, such as when constructing a space frame, the construction is often within a certain height range. After roughly determining the height by the overall height of the longitudinal truss 132, the platform at the upper end of the longitudinal truss 132 can move within the corresponding construction range by driving the hydraulic cylinder 112.

[0044] For example, refer to Figure 2 As shown, the longitudinal truss 132 includes truss cross members 1321 and truss diagonal members 1322. Here, the inclined members are uniformly defined as truss diagonal members 1322, and the non-inclined members are uniformly defined as truss cross members 1321 for ease of description. In detail, the twelve truss cross members 1321 are spliced ​​together to form a cubic frame. The two ends of each truss diagonal member 1322 are located at the connection points of two truss cross members 1321 located at any two opposite corners of the cubic frame, thus forming a stable frame structure.

[0045] For example, truss cross members 1321 and truss diagonal members 1322 of fixed length are prefabricated from circular tubes according to a 1m*1m cube specification. The assembly height can then be determined based on the specific needs of different projects. The truss cross members 1321 and truss diagonal members 1322 can be connected using bolted ball joints 140. The truss cross members 1321 and truss diagonal members 1322 can be made from circular tubes of ⌀76X3.5 mm, made of Q235B material.

[0046] At the top of longitudinal truss 132, refer to Figure 3As illustrated in the structural diagram, a top frame is provided at the top of the longitudinal truss 132, and the top frame includes four transverse trusses 131 connected to the top of the longitudinal truss 132. Specifically, in this example, the ends of the transverse trusses 131 and the ends of the longitudinal trusses 132 share a cubic frame, although multiple cubes are also possible. Thus, by integrating the end nodes of the longitudinal trusses 132 and the transverse trusses 131 into the same cubic frame, material is saved; furthermore, the twelve edges of the cubic frame form six orthogonal force transmission channels. When the longitudinal truss 132 bears construction loads, the loads can be directly transferred to the transverse trusses 131 through the four edges of the top surface of the cubic frame, forming the force-bearing mechanism of the space truss 130.

[0047] refer to Figure 4 As shown, on the side of the top frame away from the longitudinal truss 132, supports 1311 are provided at the welded joints of multiple truss cross members 1321 and truss diagonal members 1322; specifically, supports 1311 are provided at the four corners of the top frame, and when the transverse truss 131 exceeds the length of four cubic frames, one or more supports 1311 are provided in its middle section, for example... Figure 4 Four supports 1311 are provided. In this way, the bearing plane can be placed on the supports 1311, thereby stably supporting the plane to ensure the stability and load-bearing capacity of the platform.

[0048] The installed support platform 120, as shown Figure 5 As shown; the supporting platform 120 is surrounded by a prefabricated guardrail 123 with a height of not less than 1.1m as a safety enclosure. The supporting platform 120 adopts a structure fully covered with patterned steel plates 121, and angle steel 122 is set below the patterned steel plates 121. The angle steel 122 is welded to the patterned steel plates 121, and the angle steel 122 can be arranged crosswise below the patterned steel plates 121, thereby improving the structural strength of the supporting platform 120. The top platform beam can be made of rectangular tubing with a diameter of 120X120X5.

[0049] Reference structure of base 110 of the assembled mobile support frame 100 Figures 6-7 As shown; after assembly, the preferred structure meets the following design load standard values: bearing platform 120 dead load 1.0 kN / m 2 The platform has a live load capacity of 120 kN / m. 2 Basic wind pressure 0.4 kN / m 2 The horizontal load at the top of guardrail 123 is 1.0 kN / m, and the vertical load is 1.2 kN / m.

[0050] When greater operational flexibility is required, a multi-platform splicing method along the short or long direction can be chosen.

[0051] Therefore, according to some embodiments of the mobile measure frame assembly of this application, reference is made to... Figure 9 As shown, multiple movable support frames 100 described in the above embodiments are assembled along the width direction, or along the length direction; or simultaneously in the width and thickness directions, to form a movable support frame assembly with a larger load-bearing platform 120. In some examples, the longitudinal truss 132 and the transverse truss 131 of each movable support frame 100 can be assembled before the load-bearing platform 120 is installed.
