Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figures 1 to 3, the shipment method of steel case beam joint of the present invention, adopts and has under the wedge shape of track
Waterwheel 1 is fixedly connected with carrier 4, slide device and trailer coupling are set on carrier 4, trailer coupling drives by electric winch, slide device comprises parallel sliding rail 5, multiple slide block and sliding plate 9, wherein sliding rail 5 is arranged in parallel on carrier 4, on sliding rail 5, be provided with the slide block that can slide along sliding rail, on two sliding rails 5, be fixedly connected with sliding plate 9 between corresponding two slide blocks, sliding plate 9 moves on sliding rail 5 by slide block.
Sliding plate 9 upper surfaces are provided with rubber plate, between rubber plate and sliding plate 9, are fixedly connected with, and in the present embodiment, the thickness of rubber plate is that 40mm is thick, between rubber plate and sliding plate, fixes with viscose glue; The slide block of sliding plate 9 lower ends is polytetrafluoroethylene, between sliding plate 9 and slide block, fixes with positioning baffle and bolt.In the time that goods is positioned on sliding plate, because the friction force between goods and rubber plate is large, and friction force between polytetrafluoroethylene and sliding rail is little, and in the time of mobile cargo, slide block drives goods to slide on sliding rail.The end of sliding rail 9 is provided with beam joint stop 6, for preventing that goods from jumping out.
The present invention adopts wedge shape launching cradle 1 and carrier 4 to integrate with, as the harbour equipment of transition bearing goods on the bank, the structure of the wedge shape launching cradle adopting is the conventional structure in this area, structure is to have a platform and inclined-plane to enter the wedge structure that water frame forms, on the platform of wedge shape launching cradle 1, be provided with support pier, for supporting goods, place according to the goods of required shipment the position of support pier, here taking beam joint as example, the support pier position arranging can ensure carrier location afterwards and wedge shape launching cradle can link together sliding rail 5 and the support pier of wedge shape launching cradle 1 by connecting panel, before being connected with wedge shape launching cradle 1, carrier 4 should eliminate boats and ships trim and heel by adjusting ballast, what adjust ballast employing is general adjustment technology.
Goods to be installed is adopted to hydraulic pressure berth bogie toward the instrument transporting on the slide device of carrier, and the hydraulic technique that hydraulic pressure ship dolly adopts regulates the lifting of dolly, by goods bottom with arranging that hydraulic pressure ship dolly regulates the height of goods apart from sliding plate.Hydraulic pressure ship dolly moves on the track of wedge shape launching cradle, is realized advanced in unison or is retreated by control system.
Trailer coupling is installed on carrier in the present invention; owing to being that conventional technology does not mark in the accompanying drawings; be connected with goods by pull line; pull line is driven by electric winch; reverse drag device is installed on wedge shape launching cradle, and the reverse protection rope of reverse drag device drives by electric winch 2.
The inventive method Mobile steel case beam joint carries out according to following step:
First before trave lling girder joint 3 is gone on board, beam joint 3 is transported:
Internal field utilizes large flat transport trolley to carry out the transport of beam joint, be transported to dropping place after building berth, flat bed transport vehicle exits, and the correct position jack-up beam that hydraulic pressure berth bogie sails under beam joint saves and transport to wedge shape launching cradle 1 assigned address, beam is saved to 3 exactlies and put off on the steel pier on launching cradle.
Slide device and trailer coupling are set on carrier 4;
As shown in Figure 1, the view while being positioned on wedge shape launching cradle for beam joint; After laying beam joint on the berth on wedge shape launching cradle 1, carrier 4 is located and is fixedly connected with wedge shape launching cradle 1; Make the sliding rail 5 on carrier 4 save 3 supporting pier and be connected and fixed by connecting panel 8 with beam.Before being connected with wedge shape launching cradle 1, carrier 4 eliminates boats and ships trim and heel by adjusting ballast.
When beginning, sliding plate 9 is placed on the binding site of supporting pier and slippage guide rail.
Being positioned at beam on wedge shape launching cradle 1 saves 3 front and back and arranges respectively hydraulic pressure ship dolly, be specially beam save 3 centers of gravity end, front and back the left and right sides respectively cloth a hydraulic ship dolly is set, ensure that the hydraulic pressure ship dolly 7 of front end is greater than the distance of support pier rear end to slide device apart from the distance of beam joint front end.The synchronous lifting beam joint of front and back hydraulic pressure ship dolly, is transported to beam joint fore-end and moves on sliding plate, and the hydraulic pressure ship dolly 7 that is simultaneously positioned at front end halts to the supporting pier to wedge shape launching cradle 1;
Hydraulic pressure ship dolly reduces height to the height of sliding plate, beam is saved to front end and drop on and be positioned on front-seat sliding plate and support pier.
As shown in Figure 2, be operation for the first time, a part for beam joint is positioned on sliding plate, the constitution diagram when hydraulic pressure ship dolly of front end retreats to the hydraulic pressure ship dolly of rear end;
The hydraulic pressure ship dolly 7 of front end retreats to hydraulic pressure ship dolly 10 places of rear end, and the hydraulic pressure ship dolly 10 of rear end exits; The synchronous jack-up beam joint of hydraulic pressure ship dolly, drives beam joint to travel forward on sliding rail 5, and hydraulic pressure ship dolly supports again to support pier place, reduce height, the rear end of beam joint 3 is dropped on the sliding plate that is positioned at sliding rail 5 rear rows, and hydraulic pressure ship dolly exits, and state as shown in Figure 3.Sliding plate 9 is cross wall or the midfeather position of beam joint with the contact site of beam joint 3.
After beam joint all drops on slide device, beam joint is pulled to the position needing by the draw gear and the reverse drag device that start on carrier simultaneously.Subscribe behind position when being drawn to, thereby in order to prevent that beam joint from continuing the sliding rail that jumps out of slippage forward and save stop 6 by beam and stop beam to save to move on.Reverse drag device draw beam joint has slided reverse protection effect on slippage guide rail 5 by slide plate.
Beam joint 3 slides into behind the desired location on carrier on slippage guide rail 5, and on carrier 4, the steel pier of carrier bar joint is placed on desired location in advance; The hydraulic jack that jacking is used is placed on the proper site of slippage guide rail.Hydraulic jack upwards jacking simultaneously, makes beam joint entirety depart from slide plate, on beam joint load steel pier, is encased inside sleeper, and sleeper is placed and fixed the landing downwards simultaneously of rear jack top, and beam joint is dropped on load steel pier, completes the process of shipment.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
