Problems solved by technology
[0004] 1. The self-weight of the guide rail is relatively large, and the connection of multiple upper and lower guide rails has a greater self-weight, so reliable upper and lower fixing devices are required;
[0005] 2. The upper steel structure of the guide rail protrudes, which affects the lifting of the guide rail
[0006] 3. The positioning accuracy of the guide rail in the horizontal direction is controlled at ±5mm, and the positioning accuracy in the vertical direction is controlled at ±1mm. After the guide rail is connected, it is easy to swing, and it is difficult to adjust the accuracy

Embodiment Construction
[0035] Below in conjunction with specific embodiment, the technical scheme of the present invention is further described:
[0036] A guide rail installation and positioning method, such as Figure 1-6 As shown, the guide rail 1 includes a base plate 2 and two L-shaped folded plates 3, the two L-shaped folded plates 3 are respectively vertically fixed on both sides of the base plate 2, and the bent portions of the two L-shaped folded plates 3 are opposite. The positioning tool is installed by means of the guide rail, and the tool mainly includes a spreader 4, a gantry 5, and a connecting plate assembly.
[0037] Specifically, the hanger 4 is in the shape of a right-angled triangle, and a slot 7 is provided on a right-angle side of the hanger 4. The slot 7 is clamped on one side of the bottom plate 2, and the side wall of the slot 7 is provided with a fastener. The hanger 4 is installed on both sides of the bottom plate 2 through fasteners; the other right-angled side of the ha...

The invention relates to a guide rail installation and positioning tool and method. The method comprises the following steps of (1) welding and fixing retaining washers onto a ship structure; (2) connecting guide rails end to end through connecting plate components, and lifting the guide rails as a whole through a lifting appliance; (3) welding portal frames on the ship structure, enabling the guide rails to penetrate through the portal frames on which bolts are movably arranged; (4) rotating the bolts to adjust the positions of the guide rails relative to the portal frames; (5) measuring thedistances between bottom plate faces of the guide rails and the retaining washers, manufacturing adjusting washers, leaving a certain amount of fitting allowance for each adjusting washer during manufacturing, and fitting the adjusting washers; (6) connecting and fixing the guide rails, the adjusting washers, the retaining washers and the ship structure; and (7) disassembling the lifting appliance, the connecting plate components and the portal frames. Through the technical scheme provided by the invention, the guide rails can be accurately installed, the guide rail installation and positioning tool is simple in structure, easy to manufacture and convenient to use and operate, and the convenience and the safety in construction can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of ship construction, in particular to a guide rail installation and positioning tool and method. Background technique [0002] The ship is equipped with lifting equipment, so it is necessary to install guide rails. Generally, there are 2 or 4 groups of guide rails, and each group has several guide rails. The guide rails are installed on the hull structure and fixedly connected with fixing bolts. The installation accuracy does not meet the requirements, and the normal use of the lifting equipment cannot be guaranteed. [0003] During the installation of the rail, there are the following problems: [0004] 1. The self-weight of the guide rail is relatively large, and the connection of multiple upper and lower guide rails has a larger self-weight, and a reliable upper and lower fixing device is required; [0005] 2. The upper steel structure of the guide rail extends out, which affects the hoisting of the gu...
