Description

Technical Field

[0001] This utility model belongs to the field of prefabricated cabins, specifically relating to a transportation device for a prefabricated cabin roof. Background Technology

[0002] Existing top cover transport fixtures, such as Figure 1-3 As shown, it includes two end frames 11, a front tie rod 141, a rear tie rod 142, support beams (including a fixed support beam 111 and a movable support beam 13), and an anti-jump pressure plate 12. The top cover 2 is always in a horizontal state during transportation and static placement, which makes the hoisting of the tooling and the assembly / disassembly of the top cover 2 relatively simple. The support beams of the top cover 2 are at both ends of the top cover 2, and the spacing between the support points of each top cover 2 depends on the length of the top cover 2. The transportation width depends on the width of the top cover 2 and the dimensions of the tooling structure, and the transportation height depends on the number of top covers 2; wherein: the transportation tooling includes a first transportation platform 1, a top cover 2, end frames 11, an anti-jump pressure plate 12, a movable support beam 13, a tie rod assembly 14, a front tie rod 141, a rear tie rod 142, a front and rear tie rod connecting plate 15, and left and right limiting blocks 16; all the above structures are symmetrically arranged in the direction of vehicle movement; it is assumed that the number of top covers 2 transported by this structure is n. The number of end frames 11 is 2, the number of anti-jump pressure plates 12 is n, the number of movable support beams 13 is n-1, the number of front tie rods 141 and rear tie rods 142 is 4 each, the number of front and rear tie rod connecting plates 15 is 2, and the number of left and right limiting blocks 16 is 2n. The end frames 11 are symmetrical from left to right and include the following parts: fixed support beam 111, support beam legs 112, limiting posts 113, tie rod lower connector 114, tie rod lower connector 1141, tie rod upper connector 114B, frame beam 115, frame post 116, reinforcing rib one 1117, and reinforcing rib two 118. (The rest of the text is missing.) Figure 3 As shown. The number of support beam legs 112 is 2n-2, and the number of lower tie rod connectors 1141 and upper tie rod connectors 1142 are both 2. The internal clear distance between the left and right support beam legs 112 in the same horizontal plane is greater than the width of the top cover 2; the length of the movable support beam 13 is less than the horizontal internal clear distance between the two frame columns 116, and the length of the movable support beam 13 is greater than the internal clear distance between the left and right support beam legs 112.

[0003] For the above structure, the transport width of the tooling is the sum of the width of the top cover 2 and the structural dimensions of the tooling, with the width of the top cover 2 depending on the widest one. To increase adaptability, the tooling will be manufactured according to the widest top cover 2, resulting in increased transportation costs.

[0004] In existing transport fixtures, the top cover support points are all located on the end frames. The longer the top cover, the higher the requirements for the end frames, leading to increased manufacturing costs. The transport height in existing technologies can be adjusted according to the number and height of the top covers; these factors limit the use of the fixtures. Utility Model Content

The intermediate limiting frame 3 structure includes a bottom frame having two long sides; two vertical frames 31, which are respectively fixed to the two long sides and extend vertically, and the two vertical frames 31 are arranged parallel to each other in the vertical direction (each vertical frame 31 includes a top beam 313, a bottom beam 315, and two frame columns 312 fixed in a "U" structure; each bottom frame includes several bottom beams 311, the two ends of each bottom beam 311 being fixed to the bottom bottom beams 315 on the two vertical frames 31, and the bottom beams 315 being the long sides of the bottom frame; a reinforcing connecting column 314 is fixedly installed at the middle position of the vertical surface of each vertical frame 31, and the reinforcing connecting column 314 extends vertically). Extending in the direction, its bottom is fixed to the bottom beam 315, the top of the reinforcing connecting column is fixed to the top beam 313, and the end of the intermediate limiting column 34 is detachably fixed to the reinforcing connecting column 314; diagonal braces 323 are fixedly connected between the top beam 313 and the frame column 312, between the bottom beam 315 and the frame column 312, and between the bottom beam 315 and the bottom beam 313; there are two reinforcing connecting columns 314, with a gap between the two reinforcing connecting columns 314, and a reinforcing stop is fixedly connected between the gap; each top cover 2 has two intermediate limiting columns 34, and each end of the two intermediate limiting columns 34 is fixedly installed on the reinforcing connecting column 314 by bolts; two vertical frames 3 1. A top opening is formed at the top of the intermediate limiting frame 3, and a side wall opening is formed on the side wall of the intermediate limiting frame 3. The top opening and the side wall opening are connected. The top cover is placed horizontally on the bottom of the bottom frame through the top opening. Several intermediate limiting rods 34 are arranged in parallel in the vertical direction. The top cover 2 is located between two adjacent intermediate limiting rods 34 on the vertical surface of the vertical frame 31, and also below two adjacent intermediate limiting rods 34 on the horizontal surface of the vertical frame 31. Several end limiting rods 33 are divided into two corresponding groups, with each group containing [number missing]. Two end limiting rods 33 are vertically arranged and located at the bottom and top of the area between the two vertical frames. In addition, multiple support legs 35 are installed on the side wall of each vertical frame. The support legs 35 on the two vertical frames on the same horizontal plane are parallel. The lower surface of the top cover 2 rests on the top of the two or four support legs 35 located on the same horizontal plane. Each pair of corresponding end limiting rods 33 and their adjacent intermediate limiting rods 34 form a limiting mechanism. That is, the two corresponding end limiting rods 33 are used to limit the two ends of the top cover 2. The purpose of using the intermediate limiting rods 34 and the end limiting rods 33 is to limit the top cover 2 on the one hand, and to strengthen the structure of the entire transport device on the other hand.In addition, to prevent damage to the top cover 2 between the two intermediate limiting rods 34 and the two end limiting rods 33 in the vertical direction, protective sleeves (which can be made of sponge, rubber, cotton cloth, etc.) are installed on each intermediate limiting rod 34 and end limiting rod 33, or protective sleeves (such as sponge, rubber, cotton cloth, etc.) are placed directly on the top cover corresponding to the intermediate limiting sleeves 34 and end limiting rods 33.

[0028] The top frame 32 is used to cover the intermediate limiting frame, making the intermediate limiting frame complete; specifically, the top frame 32 has two continuous beams 322 and several connecting beams 321, wherein the two continuous beams 322 are parallel to the bottom beam 315 respectively, the two ends of each connecting beam 321 are fixed to the two continuous beams 322 respectively, and the several connecting beams 321 are arranged in parallel between the two continuous beams 322, and the continuous beams 322 and the connecting beams 321 located at the edge are fixedly connected by diagonal braces 323.

[0029] When the number of top covers 2 is n, and when the legs are two independent individuals (i.e., as shown in the example) Figure 6 As shown, there are two legs on the same plane on the two vertical frames. At this time, there is one support frame 31, one top frame 32, four end limiting rods 33, two intermediate limiting rods 34, four legs 35, and two corner protectors. The total number of end limiting rods 33 and intermediate limiting rods 34 is 2n, and the number of each component is an even number.

[0030] In another embodiment, when the number of top covers 2 is n, and when the support legs are whole units (not shown in the figure), the number of support frames 31 is 1, the number of top frames 32 is 1, the number of end limiting rods 33 is 4, the number of middle limiting rods 34 is 2n-4, the number of support legs 35 is 2n-2, and the number of corner protectors is 2; wherein, the total number of end limiting rods 33 and middle limiting rods 34 is 2n, and the number of each component is an even number.

[0031] This application is installed according to the following steps: as follows Figure 7 As shown, the direction of bottom beam 311 is the width direction of top cover 2, the direction of bottom beam 315 is the length direction of top cover 2, and the direction of frame column 312 is the height direction of top cover 2; the length of bottom beam 315 is less than the length of top cover 2; the top frame 32 is centrally symmetrical. First, arrange the support frame according to Figure 7 Place the top cover 2 as shown, with the top opening facing upwards, and lower it from top to bottom or from front to back onto the bottom beam 311. The flat portion of the top cover 2 should contact the bottom beam 311 (e.g., Figure 11 (as shown) Then, the four support legs 35 are fixed to the frame column 312 using a detachable fixing connection method (mainly bolts), as follows. Figure 12 As shown; the distance between the support leg 35 and the bottom beam 311 should be greater than the height of the top cover 2; the four support legs 35 should be on the same horizontal plane; then, following the order of placing the top cover 2 and installing the support legs 35, hoist the second top cover 2 from top to bottom or from front to back and place it on the support legs 35 until it is full, as shown below. Figure 13 As shown. The distance between legs 3-5 should be greater than the height of the top cover 2; Next, the top frame 32 is hoisted in, and the connecting beam 322 is connected to the top beam 313 using a detachable fixing method (mainly bolts), as follows: Figure 14 As shown.

[0032] The end limiting rod 33 and the intermediate limiting rod 34 are installed sequentially. The two ends of the end limiting rod 33 are detachably fixed to two frame columns 312 (mainly with bolts). The two ends of the intermediate limiting rod 34 are detachably fixed to two reinforcing connecting columns 314, as follows: Figure 13 As shown; this step can be carried out in stages when installing each layer of top cover 2, and it must be ensured that there are 2 intermediate limit rods 34 above each layer of top cover; at this point, the installation process of top cover 2 is completed.

[0033] II. Top Cover Transportation Status Will Figure 12 The structure shown is slowly rotated 90° along its long side, so that the top cover 2 is in a vertical position, as follows: Figure 17 As shown.

[0034] Two corner brackets 36 (mainly bolts) are detachably fixed to the second transport vehicle plate 4. The front-to-back spacing of the two corner brackets 36 meets the length requirements of the top cover 2, as follows. Figure 18 As shown; hoisting Figure 17 The structure allows each top cover 2 to be secured within the limiting space (i.e., the gap) of the corner 36, so that the top cover 2 contacts the corner top beam 363, the pad rod 362, and the limiting rod 364, as follows: Figure 4 As shown.

[0035] In this invention, during loading, the middle position of the top cover is fixed by the intermediate limiting frame structure. Then, the top cover and the intermediate limiting frame structure are rotated 90 degrees, that is, the top cover is rotated from a horizontal position to a vertical position. The end of the vertically placed top cover is then fixed by the corner bracket to achieve stable transportation of the top cover. During transportation, the top cover can be placed sideways in the transportation device. The control factors for the transportation width are adjusted to the height and quantity of the top cover, which can reduce the transportation width and thus reduce transportation costs.

[0036] 2. Because this utility model reduces the spacing between the top cover support points (i.e., from...) Figure 1 L1 in the middle is changed to Figure 4 In L2, with the same length as top cover 2, the spacing between the support points of the new tooling is shorter, and with the same strength, less material is used, which can reduce the manufacturing cost of the tooling.

[0037] 3. Because the transport height in this utility model depends on the width of the top cover and the dimensions of the tooling structure, but it is no longer a key factor in transport costs.

[0038] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
