[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As attached Figure 1 and attached Figure 7 As shown, a truss beam installation structure of an embodiment of the present invention includes several hole support channel steel rails 7, a forklift mechanism, a horizontal dragging mechanism and a vertical lifting mechanism. The forklift mechanism includes a forklift 10 and a flatbed truck 9. The upper ends of the two forks of the forklift 10 are each provided with a channel steel rail 8 arranged along the direction of the forks. The lower end of the flatbed truck 9 is slidably arranged in the channel steel rail 8. The upper end of the flatbed truck 9 is used to place the truss beam 11 to be installed. Several hole support channel steel rails 7 are installed in parallel above the reserved hole 13. There are at least two hole opening support channel steel rails 7 in each hole opening support channel steel rail 7, and the spacing between them is consistent with the spacing between the channel steel rails 8 on the two forks. The forklift mechanism is placed on one side of the hole opening support channel steel rail 7, and is used to connect the channel steel rail 8 with the corresponding hole opening support channel steel rail 7. The other side of the hole opening support channel steel rail 7 is provided with a horizontal towing mechanism for towing the flatbed truck 9 along the channel steel rail 8 and the hole opening support channel steel rail 7. The vertical lifting mechanism is installed on the roof, and is used to lift the truss beam 11 to be installed below.

[0021] The present invention uses several hole support channel steel rails 7 installed above the reserved hole 13 in parallel to each other, which not only serve as installation protection for the reserved hole 13, but also use at least two of the hole support channel steel rails 7 with the same spacing as the channel steel rails 8 on the two forks as a sliding structure for a flatbed truck 9 to carry the truss beam 11 to be installed along the channel steel rails 8 and the hole support channel steel rails 7 to move to a designated location to be installed; the coordinated arrangement of the forklift 10, the channel steel rails 8 and the flatbed truck 9 facilitates the movement of the truss beam 11 to be installed, and at the same time, The setting of the hole-opening supporting channel steel rail 7 makes it easy to move the truss beam 11 to be installed along the channel steel rail 8 and the hole-opening supporting channel steel rail 7 to the designated installation position along the flatbed truck 9; the truss beam 11 to be installed is driven to move along the channel steel rail 8 and the hole-opening supporting channel steel rail 7 by a horizontal dragging mechanism, and the truss beam 11 to be installed is lifted by a vertical lifting mechanism to complete convenient movement and installation; in this way, the problem that the conventional roof-mounted fall chain is set to lift the truss beam vertically is not convenient for installing the truss beam at the hole-opening position.

[0022] In this solution, the forklift mechanism can be provided with several holes as needed, and the hole support channel steel rails 7 are provided with a corresponding array of hole support channel steel rails 7 with the same spacing as the channel steel rails 8, and the two hole support channel steel rails 7 in each group are used to correspond to the two channel steel rails 8 on a forklift mechanism. Among them, the channel steel rails 8 can be set to allow the flatbed truck 9 to pass only on the side of the hole support channel steel rails 7.

[0023] In this solution, the opening supporting channel rail 7 can be made of I-beam.

In this way, the two sides of the truss beam 11 to be installed on the flatbed vehicle 9 are clamped and limited by the fixed baffles 5, thereby avoiding the risk of the truss beam 11 to be installed slipping off.

[0025] Among them, in a further specific embodiment based on the above, a stiffening rib is provided between the fixed baffle 5 and the flatbed vehicle 9. In this way, the stability and reliability of the support and limit of the fixed baffle 5 are guaranteed.

[0026] In another specific embodiment based on the above, the forklift 10 is a manual forklift that can be raised and lowered. In this way, the forklift 10 can be raised and lowered according to the height of the notch of the hole support channel steel rail 7, so as to ensure that the channel steel rail 8 is connected to the corresponding hole support channel steel rail 7.

[0027] In another specific embodiment based on the above, several hole support channel steel rails 7 are connected and fixed by connecting steel pipes 6. In this way, the stability and reliability of the connection structure between several hole support channel steel rails 7 can be increased by connecting steel pipes 6.

[0028] In another specific embodiment based on the above, the horizontal dragging mechanism includes two electric horizontal fall chains 3, which are arranged on the sides of the opening supporting channel steel rail 7, and are respectively used to hook on the two ends of the truss beam 11 to be installed and drag the truss beam 11 to be installed and the flatbed truck 9 along the channel steel rail 8 and the opening supporting channel steel rail 7.
