Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-7, the large-span steel structure factory building roof panel transport trolley comprises a trolley frame 1, wherein two groups of track wheels 2 are arranged below the trolley frame 1, and the distance between the two groups of track wheels 2 is the same as the distance between purlines on the upper part of a factory building roof; fixed channel-section steel of 1 upper portion rigid coupling of frame, fixed channel-section steel back-off weld in 1 surface of frame, fixed mounting gyro wheel 4 on the fixed channel-section steel web, gyro wheel 4 sets up two sets at least, and every group gyro wheel upper portion is equipped with bears slide 3, bears 3 one ends of slide and passes through rope form thing 9 and link to each other with frame 1.

The frame 1 includes two horizontal poles that are parallel to each other and is located two parallel horizontal pole both ends and the middle five parallel vertical poles, and the vertical pole all welds between two horizontal poles to form rectangular frame with the horizontal pole. Because the frame is formed by connecting rod pieces, the bicycle frame has the characteristics of simple structure, high rigidity, convenience in processing and low cost.

The purlines on the upper portion of the factory building roof are generally C-shaped steel or Z-shaped steel, the track wheels 2 of the transport trolley are groove-shaped track wheels, and the track wheels are arranged according to the intervals of the C-shaped steel or the Z-shaped steel on the roof. The rail wheels of the transport trolley are required to be arranged on two symmetrical sides by taking the central line of the cross rod as a reference in the same direction and in the same straight line. The periphery of the track wheel is provided with an annular groove. When the transport trolley runs on the C-shaped or Z-shaped steel on the roof, the transverse turned edges of the C-shaped or Z-shaped steel can be sleeved in the grooves on the two sides of the track wheels, so that the transport trolley has a good guiding effect when running, the phenomenon of derailment of the transport trolley is effectively avoided, and the running stability and safety of the transport trolley are improved. In addition, in order to avoid damage to the purlin rail surface and reduce vibration when the transport trolley runs, rubber or nylon materials are inlaid on the outer periphery of the rail wheels.

Because the span of the factory building roof is large, the distance between purlines inevitably has a little error during installation, in order to enable the track wheels to adapt to the installation error and keep the track running, as shown in figure 3, each track wheel 2 of the transport trolley is installed between two limiting plates 6, the distance between the two limiting plates 6 is greater than the width of the track wheel 2 by 5-8cm, the upper parts of the limiting plates 6 are fixedly connected with the frame 1, the lower parts of the limiting plates are provided with shaft levers 7 capable of axially moving, and the wheel shafts of the track wheels 2 are connected with the shaft levers 7. The movable shaft rod structure of the structural design can provide certain swinging amount for the track wheel, and the track wheel can adjust the distance according to purlin installation errors.

As shown in figure 4, the bearing slide way 3 of the transport trolley is provided with a pin hole, a fixed rod 5 is arranged in the pin hole, and the fixed rod 5 passes through the pin hole to be fixedly connected with the frame 1. The fixing rod 5 is kept stable when the transport trolley bears the roof panel to move, and accidental tipping in the moving process is prevented. Specifically, the fixing rod 5 can be a screw rod, a nut is welded on the frame under the C-shaped bearing slide, the screw rod or a steel bar is inserted into the pin hole and screwed with the nut, the bearing slide is fixed, and the pinch plate is prevented from being separated in the roof panel transportation process. Of course, a threaded hole can be directly formed in the frame, or other more convenient disassembly modes can be adopted to realize temporary locking of the bearing slide way.

Referring to fig. 6 and 7, two parallel fixed channel steels are symmetrically welded on the upper portion of a frame cross rod of the frame 1 according to the length of a roof panel 8, three supporting rollers 4 are evenly welded on the upper portion of each fixed channel steel, and the distance between each supporting roller and the two sides of each fixed channel steel is preferably about 2 cm. C shaped steel bearing slide 3 is placed on the upper portion of roller 4, and two apertures with the diameter of 2cm are punched on one side of bearing slide 3, one of the apertures is used for installing a rope or a chain to connect bearing slide 3 with frame 1, and the other aperture is used for inserting fixing rod 5 to fixedly connect bearing slide 3 with frame 1, thereby locking bearing slide. When the other side of the bearing slideway 3 is required to slide to the ground, the rope is in a completely stretched state, so that the pinch plate is prevented from being separated from the transport trolley.

The transportation trolley can finish the transportation work of two 300kg roof panels by only 2 persons at a time. Greatly saving the transportation cost.

The construction method for mounting the roof panel by adopting the roof panel transport trolley comprises the following specific steps:

firstly, the trolley is hoisted to the roof by a crane, grooves on two sides of rail wheels of the trolley are required to be sleeved on original purlins of the roof, the purlins are generally C-shaped or Z-shaped steel, and the rail wheels are placed on transverse curled edges of the C-shaped or Z-shaped steel. Before the roof panel is placed on the transport trolley, the fixing rod is ensured to be inserted, so that the bearing slideway is fixed with the frame, and the bearing slideway is prevented from sliding.

And secondly, hoisting 1-2 orderly stacked roof boards to the upper surface of the transport trolley by using a crane (with a hoisting frame) to ensure that the central lines of the roof boards and the transport trolley are positioned on the same straight line as much as possible so as to prevent the roof boards from toppling over.

And thirdly, two persons push the transport trolley to the installation point at the same time, the track wheels of the transport trolley are provided with grooves, derailment is not easy to occur, the advancing speeds of the two persons push the trolley to be consistent as much as possible, and the observation of whether the roof panel sideslips or not is carried out in the transportation process.

And fourthly, after the roof panel is pushed to a mounting point, the fixed rod is pulled out, two persons push forward the bearing slide way at the same time, because of the lower part of the bearing slide way, the operator can easily push the bearing slide way, the bearing slide way inclines towards the front of the frame, the roof panel slides downwards towards the front of the frame along with the bearing slide way, and the rope connected with the frame and the buckle plate at the moment are in a stretched state (the buckle plate is prevented from sliding down). The falling point of the downward sliding of the roof plate can be directly used as the mounting point according to calculation.

And fifthly, pulling the transport trolley backwards by two persons simultaneously and pulling the rope to withdraw the bearing slideway, and then the roof panel is easily and completely dismounted.

Finally, according to the operation, the transportation work of all roof panels can be completed, and finally the transportation trolley is lifted off the roof by a crane.

The method can well solve the problems of inconvenient transportation, influence on installation quality and potential safety hazard in the transportation of the existing roof panel with the installed steel structure, and can effectively reduce the transportation cost and the construction period.
