Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to a transport vehicle suitable for a composite roof of a corrugated metal plate. Background Art

[0002] At present, more and more factories are using corrugated metal sheet composite roof structure. This roof structure includes roofing strips, a bottom layer of corrugated steel sheets sequentially arranged on the roofing strips, lining supports, lining, vapor barrier, thermal insulation layer, waterproof layer, high-strength aluminum bracket, and upper corrugated metal sheet.

[0003] During the construction of a factory building, when a truck crane is used to lift roofing materials, there may be restrictions on the lifting position, and materials need to be transported from the roofing material stacking area to the roofing construction area by manpower. Since manual transportation is inefficient and affects the progress of roofing construction, roofing transportation devices are generally used to replace manual transportation.

[0004] Previous factory building panel transportation devices, such as "CN111874064A metal roof panel horizontal transportation movable bracket", "CN210530178U a roof panel reverse transportation equipment", and "CN218520363U material transportation device for steel structure roofs" can only be used for transportation on roof purlins. After the bottom layer of corrugated steel sheets is laid, the device cannot be used anymore. Therefore, this type of transportation device is only suitable for roofs with only a single layer of corrugated steel sheets laid on the upper part of the roof purlins. In the corrugated metal sheet composite roof structure, because the span of the factory building is large, up to 100 meters, and the half span can reach 50 meters, after the bottom layer of corrugated steel sheets is laid, the subsequent vapor barrier layer, thermal insulation layer, waterproof layer, and upper corrugated metal sheet and other materials are difficult to transport. Therefore, a transportation device is needed that can continue to transport on the roof after the bottom layer of corrugated steel sheets is laid. Utility Model Content

[0028] Based on the above-mentioned corrugated metal sheet composite roof structure, the utility model provides a corrugated metal sheet composite roof transport vehicle, such as Figure 1 The transport vehicle mainly comprises a vehicle frame 1, rollers 2, a wheel base 3, a limiting wheel assembly 4, a running wheel assembly 5, and a handrail 6.

[0029] The structure and connection method of each component will be described in detail below.

[0030] In the present invention, the vehicle frame 1 is a square frame structure, mainly including two long sides and two short sides, and the upper part of the vehicle frame 1 is used to place the transported materials. Rollers 2 are respectively arranged at the bottom of the two long sides of the vehicle frame 1, and the axial directions of the two rollers 2 are parallel to the long side direction. In actual use, the two rollers 2 are placed on the top surface of the roof purlin, and can realize the movement along the top surface of the roof purlin 701.

[0031] As a preferred embodiment of the present invention, the vehicle frame 1 can be welded together by a plurality of channel steels and angle steels to form a vehicle frame structure. As shown in FIG2 (a) and (c), the long side of the vehicle frame 1 should be consistent with the length of the roller 2, and the lengths of both should be greater than the sum of the spacing between two adjacent roof purlins 701 and the width of three roof purlins 701, and less than three times the spacing between adjacent roof purlins 701, to ensure that the roller 2 can be placed across three roof purlins in actual use.

[0032] Specifically, both sides of the roller 2 can be fixed to the vehicle frame 1 by welding or by a connection method such as a seat bearing.

[0033] In the present invention, wheel bases 3 are respectively arranged at the four corners of the bottom of the vehicle frame 1, and the wheel bases 3 are used to install the limiting wheel assembly 4 or the running wheel assembly 5. Among them, the limiting wheel 401 of the limiting wheel assembly 4 can rotate horizontally along the vertical wheel shaft to realize the lateral limiting of the vehicle frame 1. The track wheel 501 of the running wheel assembly 5 can rotate vertically along the horizontal wheel shaft to realize the movement on the top of the purlin 704.

[0034] As a preferred embodiment of the present invention, as shown in FIG. 2( b) and FIG. 3( b), the wheel base 3 includes two base plates arranged vertically and parallel to each other. The tops of the two base plates are fixed to the vehicle frame 1 by welding or bolting, and the side walls of the two base plates are also provided with holes for installing the limiting wheel assembly 4 or the running wheel assembly 5. The two cases will be described in detail below.

[0035] As shown in FIG2 , the limiting wheel assembly 4 mainly includes a limiting wheel 401, a limiting wheel seat 402, and a connecting bolt 403. The limiting wheel seat 402 is a U-shaped structure, including two opposite side plates and a bottom plate. The limiting wheel 401 is installed on the two opposite side plates through the wheel axle, and the bottom plate is installed on the wheel base 3 through the connecting bolt 403.

[0036] As shown in FIG3 , the running wheel assembly 5 mainly includes a track wheel 501 and a track shaft 502. The track wheel 501 is mounted on the wheel base 3 through the track shaft 502 with the track shaft 502 as the rotation axis. The distance between two track wheels 501 on the same short side should be the distance between adjacent purlins 704, and the width of the track wheel 501 is slightly larger than the width of the purlin 704. The cross section of the purlin 704 should be a "X"-shaped purlin structure, so that the track wheel 501 can move along the upper protrusion thereof.

Place the transport vehicle on the roof purlin 701 to ensure that the roller 2 is placed across three roof purlins. Since the roof purlin has a certain inclination, when the inclination is large, the limiting wheel 401 on one side can be pressed against the side of the roof purlin 701 to prevent the transport vehicle from shifting and overturning during the movement. Place the roofing material on the upper part of the vehicle frame 1, and push the transport vehicle to move by manpower to complete the reverse transportation of the bottom corrugated steel sheet and the lining purlin support, the lining purlin, and part of the roof interlayer material. When reversing large-span corrugated steel sheets, multiple transport vehicles can be set in parallel along the transportation direction, and the large-span corrugated steel sheets can be reversed by pushing multiple transport vehicles at the same time.

[0041] In actual use, when it is necessary to transport materials on the lining purlin by the transport vehicle of the utility model, the specific operation is as follows:

[0042] Install the lining purlin support 703 on the bottom corrugated steel plate 702, and install the lining purlin 704 on the lining purlin support 703. First remove the limiting wheel assembly, and then install the walking wheel assembly 5 on the wheel base 3. Install the handrail 6 in the short side direction of the vehicle frame 1 and set it on the side of human push. Place the transport vehicle on the lining purlin 704, and the track wheel 501 fits with the lining purlin 704. Place the roofing material on the vehicle frame 1, and transport the material along the length direction of the lining purlin to complete the transportation of the remaining roofing sandwich material and the upper corrugated metal plate.

[0043] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
