[0028] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] As Figure 1 , Figure 2 shown, this embodiment is a parallel transport device for the steel truss roof panels of an industrial building. Its structure mainly includes a transport rack 1 and a connecting rack 2. There are several transport racks 1, and adjacent two transport racks 1 are connected to each other through the connecting rack 2. The number of transport racks 1 and the length of the connecting rack 2 can be determined according to needs.

[0031] The connecting rack 2 and the transport rack 1 are connected by bolts.

[0032] The body of the transport rack 1 is a plate-like structure. A plate fixing mechanism 3 is arranged on the upper part of the transport rack 1, and a travel mechanism 4 is arranged on the lower part of the transport rack 1. The transport rack 1 is installed on the purlin 7 of the steel truss of the industrial building through the travel mechanism 4. The roof panel to be transported is installed on the transport rack 1 through the plate fixing mechanism 3, so as to realize the movement and transportation of the transport rack 1 carrying the roof panel along the purlin 7.

[0033] As Figure 2 shown, among them, the travel mechanism 4 specifically includes a support roller 4-5, a fixed frame 4-1, a telescopic frame 4-2, a wheel frame 4-3 and a roller 4-4, etc.

[0034] The support roller 4-5 is installed on the lower surface of the transport rack 1 through a rotating shaft. The rotating shaft of the support roller 4-5 is parallel to the lower surface of the transport rack 1, and the axial direction of the support roller 4-5 is consistent with the width direction of the transport rack 1. When installed on the purlin 7, the support roller 4-5 contacts the top surface of the purlin 7, so as to support the entire transport rack 1, and the friction between the transport rack 1 and the top surface of the purlin 7 is reduced by the rotation of the support roller 4-5.

[0035] At the same time, the travel mechanism 4 includes two groups of rollers 4-4. The rollers 4-4 are installed on the wheel frame 4-3. The two wheel frames 4-3 are arranged oppositely. The rollers 4-4 are located inside the wheel frame 4-3. The web of the purlin 7 is clamped by the two groups of rollers 4-4, so as to limit the transport rack 1 to only move along the purlin 7. On the arc-shaped or inclined steel truss of the industrial building, the transport rack 1 will not break away from the purlin 7, and the purlin 7 serves as the track of the transport rack 1.

[0036] To facilitate the installation and removal of the transport rack 1 and enable the wheel rack 4-3 to move horizontally, two opposite fixed racks 4-1 are provided on the lower surface of the transport rack 1. A telescopic rack 4-2 is inserted through the fixed rack 4-1, and the wheel rack 4-3 is connected to the telescopic rack 4-2. The horizontal movement of the wheel rack 4-3 is achieved through the telescopic rack 4-2, thereby realizing the mutual approach or separation of the two groups of rollers 4-4. After the two groups of rollers 4-4 are separated from each other, the transport rack 1 can be conveniently placed on the purlin 7 or removed from the purlin 7. After the transport rack 1 is placed on the purlin 7, the two groups of rollers 4-4 are made to approach each other and clamp the web of the purlin 7, thereby stably installing the transport rack 1 on the purlin 7.

[0037] Furthermore, an elastic member 4-6 is provided between the wheel rack 4-3 and the fixed rack 4-1. The elastic member 4-6 is generally a spring, and the elastic member 4-6 can make the two wheel racks 4-3 automatically approach each other to achieve automatic clamping.

[0038] Specifically, the telescopic rack 4-2 includes two rack bars. The rack bars pass through the fixed rack 4-1, the inner ends of the rack bars are connected to the wheel rack 4-3, and the spring is sleeved on the rack bars.

[0039] Furthermore, the outer ends of the two rack bars pass through the outer surface of the fixed rack 4-1 and are connected to each other by a cross bar. The cross bar and the two rack bars are connected to form a U-shaped handle. Through the handle, the telescopic rack 4-2 can be quickly pulled to drive the wheel rack 4-3 and the rollers 4-4 to move, realizing the quick operation of installing or removing the transport rack 1.

[0040] As Figure 3 shown, the sheet fixing mechanism includes a pressing plate 3-1. The pressing plate 3-1 is hinged to the transport rack 1. An elastic mechanism 3-2 is provided between the pressing plate 3-1 and the transport rack. The elastic mechanism 3-2 is used to drive the end of the pressing plate 3-1 to approach the transport rack 1. In this embodiment, the elastic mechanism 3-2 is a spring. The spring is in a compressed state and is located outside the hinge shaft. Through the elastic force of the spring, the pressing plate 3-1 on the inner side of the hinge shaft is pressed against the upper surface of the transport rack 1. A handle is provided on the pressing plate 3-1, and through the handle, the pressing plate 3-1 can be opened to facilitate the placement or removal of the roof panel.

[0041] A towing rope 5 is connected to the transport rack 1. The towing rope 5 is detachably connected to the transport rack 1 through a hook or the like. The transport rack 1 is towed along the purlin 7 through the towing rope 5.

[0042] The parallel transportation device for the steel truss roof panels of the industrial building of the present utility model can be installed on the purlin 7 of the steel truss of the industrial building, and use the purlin 7 as a track to move along the purlin 7. The roof panel to be transported is fixed on the transport rack 1 and moves along the purlin 7 together with the transport rack 1, which can greatly improve the conveying speed and efficiency of the roof panel on the steel truss of the industrial building, and there is no need for manual transportation, reducing the danger of construction workers during construction.

[0043] Embodiment 2

[0044] This embodiment is a parallel transportation construction method for the steel truss roof panels of the industrial building, which is realized based on the above-mentioned parallel transportation device for the steel truss roof panels of the industrial building. The steel truss roof of the existing large-scale factory building includes several steel trusses, and purlins 7 are arranged between adjacent steel trusses. The purlins 7 are fixedly installed on the top surface of the upper chord 6 of the steel truss. The length direction of the purlins 7 is consistent with the length direction of the factory building, and the purlins 7 are connected end to end in sequence to form a straight line in the length direction of the factory building. The roof panels are laid on the purlins 7. This structure of the existing steel truss roof of the factory building provides a structural basis for the realization of the present utility model.

[0045] The parallel transportation construction method for the steel truss roof panels of the industrial building specifically includes the following steps.

[0046] a. Two traction devices are arranged on the roof of the industrial building. One end of the factory building is used as the hoisting area for the roof panels, and one of the traction devices is located at this position. The above-mentioned parallel transportation device for the steel truss roof panels of the industrial building is arranged at the end of the roof. Several transport racks 1 are connected into a whole through connecting parts, and the traveling mechanism 4 is installed on the purlin 7. The traction device is connected to the transport rack 1 through a traction rope 5.

[0047] Use two traction devices to traction the transportation device from both ends to realize the rapid movement of the transportation device between the two traction devices. Generally, the two traction devices are respectively located at both ends of the length direction of the factory building. One end of the factory building is used as the hoisting area, and the roof panels are conveyed from this end along the purlin 7 to the other end of the factory building. If the length of the factory building is relatively long, the transportation efficiency of the roof panels will be reduced. It can be selected to set one traction device at the end of the factory building and the other traction device in the middle of the length direction of the factory building. First, install the roof panels on one half of the factory building, and then use the same method to convey and install the roof panels on the other half.

[0048] b. Hoist the roof panel to the end of the roof through the ground auxiliary hoisting equipment, place the roof panel on the transport rack 1, and use the plate fixing mechanism 3 to fix the roof panel on the transport rack 1.

[0049] Pre - transport the roof panels to the ground at the end of the factory building in advance, and then use a crane or other lifting device to lift the roof panels on the ground to the roof, and place and fix the roof panels on the transport device manually. The specific operation is as follows: Place the roof panel removed from the lifting equipment on the upper surface of the transport rack 1, then lift the pressure plate 3 - 1 upward, move the roof panel under the pressure plate 3 - 1, and release the pressure plate 3 - 1 so that the pressure plate 3 - 1 presses the roof panel tightly on the transport rack 1.

[0050] c. Start the traction device to pull the parallel transport device for the steel truss roof panels of the industrial factory building to move along the purlin 7 to the required position.

[0051] d. Release the sheet - fixing mechanism and remove the roof panel for the installation construction of the roof panel.

[0052] The specific operation is as follows: Lift the pressure plate 3 - 1 upward, then remove the roof panel from the transport rack 1, release the pressure plate 3 - 1, and the pressure plate 3 - 1 automatically resets under the elastic force of the spring.

[0053] e. Start the traction device to pull the parallel transport device for the steel truss roof panels of the industrial factory building to move along the purlin 7 in the reverse direction to the original position.

[0054] f. Repeat steps b - e until a row of roof panels is laid.

[0055] g. After each row of roof panels is laid, move the positions of the traction device and the parallel transport device for the steel truss roof panels of the industrial factory building so that they correspond to another row of roof panels until all the roof panels are laid.

[0056] Among them, when installing or disassembling the parallel transport device for the steel truss roof panels of the industrial factory building, pull the two telescopic frames 4 - 2 to separate the two groups of rollers 4 - 4, so that the purlin 7 enters between the two groups of rollers 4 - 4 or moves out from between the two groups of rollers 4 - 4, and then release the two telescopic frames 4 - 2 to make the two groups of rollers 4 - 4 return to the original position.

[0057] When installing the transport device, determine the width of the connecting frame 2 according to the spacing of the steel truss purlins 7, and at the same time determine the number of transport racks 1 in combination with the width of the roof panel.

[0058] For the roof panels with a shorter length, when installing the parallel transport device for the steel truss roof panels of the industrial factory building, the sheet - fixing mechanism is located at the rear side in the forward direction. Since the length of the roof panel is shorter, after being fixed on the transport rack 1, the length of its front end extending out of the transport rack 1 is shorter and there will be no obvious bending deformation. During transportation, the front end of the roof panel will not contact the purlin 7, so it can be transported forward smoothly. After reaching the position, after releasing the pressure plate 3 - 1, the transport device retreats a certain distance and then the roof panel can be directly unloaded at the predetermined position. Disconnect the traction rope 5 at the front end of the pressure plate 3 - 1, bypass it above the roof panel and reconnect it to the transport rack 1.

[0059] For a relatively long roof panel, when installing the parallel transportation device for the steel truss roof panel in an industrial building, it is necessary to place the plate fixing mechanism on the front side in the forward direction. When the front end of the roof panel is fixed on the transportation device, its rear end may come into contact with the purlin 7 due to deformation caused by gravity or other reasons. However, since it is located at the rear end in the forward direction, after taking measures such as wrapping and protection, it can prevent the purlin 7 from wearing the roof panel. After transportation in place, it is necessary to carry the plate to the front of the transportation device, or remove the transportation device from the purlin 7, move it to the rear of the plate, and then reinstall it on the purlin 7.

[0060] The utility model can quickly transport the roof panel to the corresponding position of the steel truss in the industrial building, so as to facilitate the subsequent installation construction of the roof panel. The transportation device can be adjusted to adapt to different purlin 7 spacings and roof panel widths, and is suitable for the transportation and installation construction of most steel truss roof panels in industrial buildings.
