Among the figure, 1 is that wedge shape launching cradle, 2 is the hydraulic pressure ship dolly of rear end for connecting panel, 9 for sliding plate, 10 for beam saves stop, 7 for the hydraulic pressure ship dolly, 8 of front end for sliding rail, 6 for carrier, 5 for beam joint, 4 for electric winch, 3.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail:
Shown in Fig. 1 ~ 3, the shipment method of steel case beam joint of the present invention adopts to have under the wedge shape of track
Waterwheel 1 is captiveed joint with carrier 4, at carrier 4 slide device and trailer coupling are set, trailer coupling drives by electric winch, slide device comprises parallel sliding rail 5, a plurality of slide block and sliding plate 9, wherein sliding rail 5 is arranged in parallel on the carrier 4, be provided with the slide block that can slide along sliding rail on the sliding rail 5, be fixedly connected with sliding plate 9 between corresponding two slide blocks on two sliding rails 5, sliding plate 9 is mobile at sliding rail 5 by slide block.
Sliding plate 9 upper surfaces are provided with rubber plate, and rubber plate is captiveed joint with 9 of sliding plates, and the thickness of rubber plate is that 40mm is thick in the present embodiment, fixes with viscose glue between rubber plate and sliding plate; The slide block of sliding plate 9 lower ends is polytetrafluoroethylene, fixes with positioning baffle and bolt between sliding plate 9 and slide block.When goods was positioned on the sliding plate, because the friction force between goods and the rubber plate is large, and the friction force between polytetrafluoroethylene and the sliding rail was little, and when mobile cargo, slide block drives goods and slides at sliding rail.The end of sliding rail 9 is provided with beam joint stop 6, is used 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 that adopts is this area structure commonly used, structure is the wedge structure with a platform and the formation of inclined-plane entry frame, be provided with support pier on the platform of wedge shape launching cradle 1, be used for supporting goods, place according to the goods of required shipment the position of support pier, here take the beam joint as example, the support pier position that arranges can guarantee behind the carrier location and the wedge shape launching cradle can link together the support pier of sliding rail 5 with wedge shape launching cradle 1 by connecting panel, carrier 4 with should eliminate boats and ships trim and heel by adjusting ballast before wedge shape launching cradle 1 is connected, what adjust that ballast adopts is general adjustment technology.
The instrument that goods to be installed is transported on the slide device of carrier adopts hydraulic pressure berth bogie, and the hydraulic technique that hydraulic pressure ship dolly adopts is regulated the lifting of dolly, by in the goods bottom with arranging that hydraulic pressure ship dolly regulates goods apart from the height of sliding plate.Hydraulic pressure ship dolly moves at the track of wedge shape launching cradle, realizes advanced in unison or retreats by control system.
Trailer coupling is installed on the carrier among the present invention; owing to being that conventional technology does not mark in the accompanying drawings; link to each other with goods by pull line; pull line is driven by electric winch; at the wedge shape launching cradle reverse drag device is installed, 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:
At first before trave lling girder joint 3 is gone on board, beam joint 3 is transported:
The internal field utilizes the large flat transport trolley to carry out the transportation of beam joint, be transported to dropping place behind the building berth, flat bed transport vehicle withdraws from, and hydraulic pressure berth bogie sails the correct position jack-up beam joint under the beam joint into and transports to wedge shape launching cradle 1 assigned address, beam is saved 3 exactlies put off on the steel pier on the launching cradle.
Slide device and trailer coupling are set on the carrier 4;
View when as shown in Figure 1, being positioned on the wedge shape launching cradle for the beam joint; After laying beam joint on the berth on the wedge shape launching cradle 1, carrier 4 is located and is captiveed joint with wedge shape launching cradle 1; The supporting pier that makes sliding rail 5 and beam joint 3 on the carrier 4 be connected and fixed by connecting panel 8.Before being connected with wedge shape launching cradle 1, carrier 4 eliminates boats and ships trim and heel by adjusting ballast.
Sliding plate 9 is placed on the binding site of supporting pier and slippage guide rail during beginning.
Being positioned at beam on the 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 the end, front and back the left and right sides respectively cloth a hydraulic ship dolly is set, the hydraulic pressure ship dolly 7 that guarantees front end apart from the distance of beam joint front end greater than the distance of support pier rear end to slide device.Hydraulic pressure ship dolly synchronous lifting beam joint in front and back is transported to beam joint fore-end and moves on the sliding plate, and the hydraulic pressure ship dolly 7 that is positioned at simultaneously 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 front end drop on the sliding plate and support pier that is positioned at the front row.
As shown in Figure 2, be for the first time operation, the part of beam joint is positioned on the sliding plate, the constitution diagram when the 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 withdraws from; The synchronous jack-up beam joint of hydraulic pressure ship dolly drives the beam joint and travels forward at sliding rail 5, and hydraulic pressure ship dolly supports again to the 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 withdraws from, and state as shown in Figure 3.Sliding plate 5 is cross wall or the midfeather position of beam joint with the contact site of beam joint 3.
After the beam joint all dropped on the slide device, the draw gear and the reverse drag device that start simultaneously on the carrier were pulled to the position that needs with the beam joint.When be drawn to subscribe the position after, thereby in order to prevent that the beam joint from continuing the forward slippage sliding rail that jumps out and stoping the beams joint to move on by beam joint stop 6.Reverse drag device draw beam joint has slided the reverse protection effect by slide plate at slippage guide rail 5.
Beam joint 3 is after slippage guide rail 5 slides into desired location on the carrier, and the steel pier of carrier bar joint is placed on the desired location in advance on the carrier 4; The hydraulic jack that jacking is used is placed on the proper site of slippage guide rail.Hydraulic jack is upwards jacking simultaneously, makes the whole slide plate that breaks away from of beam joint, is encased inside sleeper at beam joint load steel pier, and sleeper is placed and fixedly simultaneously landing downwards of rear jack top, and the beam joint is dropped on the load steel pier, finishes the process of shipment.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
