Description

Technical Field

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

[0002] Due to height restrictions in road transport and the need for easy hoisting of prefabricated modules during use, the top cover of certain types of prefabricated modules is often made movable. This reduces transportation costs and facilitates on-site operations. When a project uses a large number of top covers, a structure needs to be considered for transporting them, ensuring that transportation does not damage the quality of the top covers while also reducing transportation costs.

[0003] Currently, there are two types of roof transport structures, one of which is as follows: Figure 1 As shown, the top covers 2 are stacked one on top of the other on the transport vehicle platform 1, with the top covers 2 in contact with each other. If the top covers have the same width, temporary parts 3 are welded together along the width direction of the top covers 2 to connect the upper and lower top covers 2; if the top covers 2 have the same length, temporary parts are welded together along the length direction of the top covers 2 to connect the upper and lower top covers 2; another method is as follows... Figure 2 As shown, the top cover 2 is erected and placed on the transport vehicle platform 1, and placed side by side in the width direction of the vehicle body; the top covers 2 are fixed together with temporary parts 3, and the top covers 2 have lifting points 4;

[0004] However, the first transportation method has the following disadvantages: 1) Temporary parts 3 will damage the top cover 2; 2) Contact between top covers 2 will damage the top cover 2; 3) If the width or length of the top covers 2 is inconsistent, there will be requirements for temporary parts 3, and they cannot be transported together; 4) If the transportation conditions are bad, the top cover 2 may detach from the transport vehicle platform 1; 5) It cannot be transported as a whole. However, the second transportation method has the following disadvantages: 1) Temporary parts 3 will damage the top cover 2; 2) The lifting points 4 of the top cover 2 cannot be used, which poses a risk of unsafe lifting; 3) If the transportation conditions are bad, the top cover 2 may detach from the transport vehicle platform 1; 4) It cannot be transported as a whole.

[0005] To address the shortcomings of existing technologies, this utility model provides a transport structure for prefabricated cabin roofs, with a roof support space to fix the distance between roofs; facilitating the loading and unloading of roofs within the movable support space of this transport structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A transport structure with a prefabricated cabin roof, comprising,

[0008] Two end frames are symmetrically arranged; and the end frames have a height direction, a width direction and a length direction.

[0009] Two tie rod assemblies are symmetrically fixedly installed between the two end frames;

[0010] The two end frames and two tie rod assemblies form a top cover bearing space, which extends vertically and is open, and the top cover is placed within the top cover bearing space.

[0011] Preferably, the end frame includes,

[0012] Frame beams, which extend along the width direction.

[0013] A fixed support beam extends along its width.

[0014] Two frame columns, both of which extend along the height direction, and form a "U"-shaped structure with the frame beam and fixed support beam through tie rod connectors;

[0015] Several support beam legs are fixed to the frame columns at equal intervals along the height direction, and the support beam legs on two frame columns correspond to each other. Movable support beams are provided on the support beam legs.

[0016] Two limiting posts, one end of which is fixed to the fixed support beam and extends along the height direction until the other end is fixed to the frame beam.

[0017] Preferably, the tie rod connector includes,

[0018] The tie rod has a connector at one end fixed to the frame beam and extending along the length direction, and is fixed to the top of the frame column;

[0019] The lower connector of the tie rod is fixed at one end to the fixed support beam and extends along the length direction, and is connected to the bottom of the frame column.

[0020] Preferably, one end of the upper connector of the tie rod is fixed to the frame beam, and one end of the lower connector of the tie rod is fixed to the fixed support beam, so that the frame beam and the fixed support beam are respectively in two vertical planes, that is, the frame beam and the fixed support beam are misaligned.

[0021] Preferably, the inner clearance between the corresponding support beam legs on the two frame columns is greater than the width of the top cover, the length of the movable support beam is less than the horizontal inner clearance between the frame columns, and the length of the movable support beam is greater than the inner clearance between the corresponding support beam legs on the two frame columns.

[0022] Preferably, the end frame further includes,

[0023] Two reinforcing ribs, which are in the shape of an "X" and fixed to both ends of the frame beam and the two tie rod lower connectors;

[0024] Two reinforcing ribs are fixed together to the fixed support beam, and each of the two reinforcing ribs extends along the length direction.

[0025] Preferably, each of the tie rod assemblies includes two front tie rods, two rear tie rods, and a front and rear tie rod connecting plate.

[0026] Furthermore, both front tie rods and both rear tie rods are detachably and fixedly connected to the front and rear tie rod connecting plates to form an "X" shaped tie rod structure.

[0027] One end of one of the front pull rods is detachably and fixedly connected to the upper connector of the pull rod, and one end of the other front pull rod is detachably and fixedly connected to the lower connector of the pull rod;

[0028] One end of one of the rear pull rods is detachably and fixedly connected to the upper connector of the pull rod on the other end frame, and one end of the other rear pull rod is detachably and fixedly connected to the lower connector of the pull rod on the other end frame.

[0029] Preferably, each of the tie rod assemblies includes a front tie rod and a rear tie rod.

[0031] Preferably, an anti-jumping pressure plate is installed on both of the limiting posts. The anti-jumping pressure plate extends along the width direction and is located above the top cover, with a gap between them.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] 1. Because the top cover bearing space in this utility model is fixed by the distance between the top covers, that is, the inner clear distance between the corresponding support beam legs on the two frame columns is greater than the width of the top cover, the length of the movable support beam is less than the horizontal inner clear distance of the frame columns, the length of the movable support beam is greater than the inner clear distance between the corresponding support beam legs on the two frame columns, and the distance between the two opposing limiting blocks located on the same movable support beam is greater than the width of the top cover; thus, it is convenient to load and unload the top cover in the movable bearing space of the transport structure.

[0034] 2. Because the contact between the transport structure and the top cover in this utility model is non-fixed, the transport structure will not damage the top cover during transport or hoisting.

[0035] 3. Because this utility model can be used for mixed transport of top covers of different widths using the same tooling, it is only necessary to ensure that top covers of different widths can be installed in the bearing space of the top cover.

[0036] 4. Because the transport structure and the top cover are an integral unit in this utility model, they can be hoisted as a whole and transferred on different transport vehicles.

[0037] 5. Because the lifting points of the top cover itself can be used for hoisting in this utility model, the hoisting safety is guaranteed; and when the top cover is hoisted into or away from the transport structure, the operation is convenient and safe, and there is no risk of the top cover and the transport structure tipping over; the transport structure can be adjusted according to the length of the top cover and can be reused.

[0051] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0052] like Figure 1-11 As shown, a transport structure for a prefabricated cabin roof includes,

[0053] Transport vehicle pallet 1,

[0054] Two end frames 11 are symmetrically fixedly installed at both ends of the upper surface of the transport vehicle platform 1. Each end frame 11 has dimensions in the height, width, and length directions (e.g., [missing information]). Figure 2 (as shown)

[0055] Two tie rod assemblies are symmetrically fixed between the two end frames 11;

[0056] The transport vehicle platform 1, the two end frames 11 and the two tie rod assemblies form a top cover bearing space, and the top cover bearing space extends vertically and is open, with the top cover 2 placed inside the top cover bearing space.

[0057] End frame 11 includes,

[0058] Frame beam 115 extends along its width.

[0059] Fixed support beam 111 extends along the width direction.

[0060] Two frame columns 116, both of which extend along the height direction, and form a "U"-shaped structure with the frame beam 115 and the fixed support beam 111 through tie rod connectors 114;

[0061] Several support beam legs 112 are fixed at equal intervals along the height direction on the frame column 116, and the support beam legs 112 on two frame columns 116 correspond to each other. Movable support beams 13 (mainly sleeved) are provided on the support beam legs 112.

[0062] Two limiting posts 113, one end of which is fixed to the fixed support beam 111 and extends along the height direction until the other end is fixed to the frame beam 115;

[0063] Two reinforcing ribs 118 are fixed together to the fixed support beam 111, and each reinforcing rib 118 extends along the length direction.

[0064] The internal clear distance between the corresponding support beam legs 112 on the two frame columns 116 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 of the frame columns 116. The length of the movable support beam 13 is greater than the internal clear distance between the corresponding support beam legs 112 on the two frame columns 116.

[0065] In addition, when the top cover 2 is placed on the transport structure, a limiting block 16 is fixed on each support beam leg 112, and the limiting block 16 extends along the length direction, and the distance between two opposing limiting blocks 16 on the same movable support beam 13 is greater than the width of the top cover 2; when the top cover 2 is hoisted, step S1. First, the first top cover 2 is hoisted from top to bottom along the height direction and placed on the fixed support beam 111, located in the installation bearing cavity, and between two opposing limiting blocks 16 on the same movable support beam 13; S2. An anti-jump pressure plate 12 is installed on the limiting post 113, the anti-jump pressure plate 12 is at the upper edge of the top cover 2, and there is a certain distance between the two; then, following the above steps S1-S2, the second, third...nth top covers are hoisted; after all the top covers are installed, the whole is hoisted onto the transport vehicle 1, and the transport structure and the transport vehicle 1 are fixed.

[0066] Before the top cover 2 is hoisted in, the transport vehicle platform 1 has already completed partial connections, and the connection relationship is as follows: the tie rod assembly 114 includes,

[0067] The tie rod has a connector 1142, one end of which is fixed to the frame beam 115 and extends along the length direction, and is fixed to the top of the frame column 116.

[0068] The tie rod lower connector 1141 is fixed at one end to the fixed support beam 111 and extends along the length direction, and is connected to the bottom of the frame column 116.

[0069] In addition, the end frame 11 also includes two reinforcing ribs 117, which are "x" shaped and fixed to both ends of the frame beam 115 and the two tie rod lower connectors 1141.

[0070] One end of the upper connector 1142 of the tie rod is fixed to the frame beam 115, and one end of the lower connector 1141 of the tie rod is fixed to the fixed support beam 111, so that the frame beam 115 and the fixed support beam 111 are respectively in two vertical planes, that is, the frame beam 115 and the fixed support beam 111 are misaligned.

[0071] Each tie rod assembly includes two front tie rods 141, two rear tie rods 142, and a front and rear tie rod connecting plate 15.

[0072] Furthermore, both front tie rods 141 and both rear tie rods 142 are detachably and fixedly connected (specifically, bolted) to the front and rear tie rod connecting plates 15, forming an "X"-shaped tie rod structure.

[0073] One end of one of the front pull rods 141 is detachably and fixedly connected to the upper connector 1142 of the pull rod (specifically, a bolt connection), and one end of the other front pull rod is detachably and fixedly connected to the lower connector 1141 of the pull rod (specifically, a bolt connection).

[0074] One end of one of the rear pull rods 142 is detachably and fixedly connected (specifically, by bolt) to the upper pull rod connector 1142 on the other end frame 11, and one end of the other rear pull rod 142 is detachably and fixedly connected (specifically, by bolt) to the lower pull rod connector 1141 on the other end frame 11.

[0075] Two limit posts 113 are equipped with anti-jump pressure plates 12 (mainly bolted connections). The anti-jump pressure plates 12 extend along the width direction and are located above the movable top cover 2, with a gap between them.

[0076] When using the above-mentioned transport structure, the transport structure can be hoisted onto the transport vehicle platform 1 first (after hoisting, the transport structure is fixed to the transport vehicle platform by straps or by welding), or the top cover 2 can be filled first and then hoisted onto the transport vehicle platform 1. This embodiment mainly adopts the latter.

[0077] During disassembly, first loosen the bolts between the upper front tie rod 141 and the upper rear tie rod 142 and the front and rear tie rod connecting plate 15, thus connecting the front tie rod 141 and the rear tie rod 142 to the front and rear tie rod connecting plate 15 respectively. Place one end of the upper front tie rod 141 and the upper rear tie rod 142 on the ground. Then loosen the bolts between the lower front tie rod 141 and the lower rear tie rod 142 and the front and rear tie rod connecting plate 15, as well as the bolts between them and the lower connecting piece of tie rod 1141. Next, loosen the bolts between one end of the lower front tie rod 141 and the lower rear tie rod 142 and the lower connecting piece of tie rod 1141, placing the other end on the ground. This prevents the end frame 11 from tipping over during disassembly. Additionally, the bolts between the front tie rod 141 and the rear tie rod 142 and the end frame 11 allow the front tie rod 141 and the rear tie rod 142 to serve as a support structure during installation or disassembly.

[0078] In this application, by adjusting the height of the movable support beam 13 (mainly by adjusting the height of the support beam legs 112), top covers 2 of different heights can be installed within the top cover bearing space.

[0079] By adjusting the distance between two opposing limiting blocks 16 on the same movable support beam 13 (mainly for installing top covers of different widths, and the limiting blocks also play an auxiliary limiting role for top covers of different widths), top covers 2 of different widths can be installed within the top cover bearing space.

[0080] By adjusting the lengths of the front tie rod 141 and the rear tie rod 142 (mainly by replacing tie rods of different lengths or by pre-setting different detachable fixing connection points (i.e. bolt holes) on the same front tie rod 141 and the rear tie rod 142, and installing them on the front and rear tie rod connecting plates through the detachable fixing connection points (i.e. bolt holes) at different positions, the lengths of the front tie rod 141 and the rear tie rod 142 can be changed), top covers 2 of different lengths can be installed within the top cover bearing space.

[0081] In addition, the cross-sections at both ends of the movable support beam 13 are inverted U-shaped and are not fixedly connected to the end frame 11 (the movable support beam 13 is placed directly on the support beam leg 112 or the movable support beam 13 is fixed to the support beam leg 112 by bolts), which facilitates the installation or removal of the top cover 2.

[0082] Furthermore, in this transportation structure, it is assumed that the number of transport top covers 2 is n; the number of end frames is 2; the number of anti-jump pressure plates is 2n; the number of movable support beams 13 is 2n-2; 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; the number of limiting blocks 16 on the same movable support beam 13 and the number of limiting blocks 16 on the fixed support beam 111 is 2n in total; 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 is 2 each.

[0083] In addition, there is another embodiment, namely as follows: Figure 12 As shown, it is basically the same as the above embodiment, except that the front and rear tie rod connecting plates 15 are not set in this embodiment. Instead, the front tie rod 141 and the rear tie rod 142 are both treated as a single piece. Both the front tie rod 141 and the rear tie rod 142 are directly fixed to the end frame 1, and the front tie rod 141 and the rear tie rod 142 form an X shape. The purpose is to address the issue that when the front tie rod 141 and the rear tie rod 142 are cut during the unloading of the top cover on site, they may suddenly break apart due to stress, which could easily injure people. In addition, the end frame is prone to tipping over when the top cover is unloaded on site without support. Therefore, the front tie rod 141 and the rear tie rod 142 are directly replaced with bolt connections, which is both safe and convenient for on-site operation.

[0084] 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 within the scope of the appended claims without creative effort are still within the scope of protection of this patent.
