Abstract
The utility model discloses a working platform suitable for mounting an LNG (Liquefied Natural Gas) ship cargo hold containment system. The working platform comprises a ten-layer main structure composed of a plurality of columns, a plurality of cross beams and a plurality of longitudinal beams; supporting legs with different structures are connected to the end parts each layer of the main structure; and rectangular tube-shaped telescopic girders are mounted at the end parts of the cross beams or the longitudinal beams of each layer of the main structure. The end parts of the layers of the main structure except for the top surface have scalability, so that proper distance between the working platform and a bulkhead as well as proper distance among the working platform and two heat insulation layers are always kept, and operating staff can safely and conveniently mount the containment system on the working platform, and the working platform is not removed until the mounting operation is completely finished.
Description
Technical field
The utility model relates to LNG shipload cabin containment system, particularly relates to the workplatform that a kind of LNG of being applicable to shipload cabin containment system is installed.
Background technology
The LNG ship is a kind of special boat that is used for conveying liquified natural gas, and the temperature of liquefied natural gas is-163 ℃, cannot the direct contact hull plate, so on the inner steel plate of cargo hold, fill the fully enclosed heat-barrier coating, and Here it is cargo hold containment system.Thermal insulation layer is made up of 2 layers of insulated case and 2 layers of invar film, and insulated case plays heat-blocking action, and invar plays airtight leakage-preventing effect.Generally there are 10 faces in LNG shipload cabin, and each face all need be installed thermal insulation layer, carries out erection work thereby need a workplatform, Here it is containment system erecting stage.
In the ship building process, for carrying out in the high-altitude that the enterprising luggage of bulkhead is joined or work such as electric welding, we adopt the mode of conventional steel pipe scaffold as workplatform of setting up usually.Because each face (comprising the bottom surface) all will be installed 2 layers of thermal insulation layer in the LNG shipload cabin, that is before and after installing, and the distance of bulkhead will certainly change in each face end of workplatform and the cargo hold; And in the normal mounting process, need be with the equipment of differing heights on thermal insulation layer, the distance of bulkhead also will change in each face end of that workplatform and the cargo hold.If as workplatform, that will realize the variable in distance of each face end to bulkhead, just must remove former scaffold, sets up again according to new location again with conventional steel pipe scaffold.Do like this, following weak point arranged: 1) in the thermal insulation layer installation process, scaffold must dismounting several times, prolonged the duration; 2) increase a lot of labor costs; 3) because the invar film of installing has only 0.7mm thick, a little less than being highly brittle, repeated disassembled and assembled will certainly increase the probability that destroys the invar film.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, the workplatform that provides a kind of LNG of being applicable to shipload cabin containment system to install, and each face of this flat-bed is reconciled height through supporting leg.
The utility model technical matters solution is following:
A kind of workplatform that is applicable to that LNG shipload cabin containment system is installed; Be characterised in that its formation comprises: 10 aspect main structures forming by many root posts, many crossbeams and Duo Gen longeron; Between whenever two-layer highly is 2.5m to 2.8m; The 3rd layer and the 10th layer is full shop layer, and other each layer is just having shop layer structure near the bulkhead place, and the shape of whole workplatform and described cargo hold adapts; The head end face of workplatform and breech face are vertical surface; The ground floor of larboard or starboard and the side of the second layer are lower inclined plane; The 3rd layer of side to layer 7 is vertical surface; The 8th layer to the tenth layer side is a ramp; Below many root posts of the periphery of said ground floor, be arranged with vertical support leg, be connected with the diagonal ligament leg in the end of many crossbeams of described lower inclined plane, the end horizontal of many crossbeams of said vertical surface be provided with the horizontal support leg; The flexible fine strain of millet of rectangular tubular is installed in the end of the crossbeam of each aspect of described workplatform or longeron, below the crossbeam of the lower inclined plane end of the side of the ground floor of larboard or starboard and the second layer, is provided with the track that has a plurality of pin-and-holes.
Described vertical support leg, diagonal ligament leg and horizontal support leg constitute by inner sleeve that has a plurality of pin-and-holes and base; There is double-screw bolt the below of this inner sleeve; Be with nut on this double-screw bolt; The outer chamfering of one circle arc is arranged at the bottom of this nut, and in the groove that embeds chamfering in the circle arc on the said base, this nut is installed with handle outward.
The inner sleeve of described diagonal ligament leg also is with the diagonal ligament leg outer tube that vertically has a plurality of pin-and-holes outward, and the top horizontal direction of this diagonal ligament leg outer tube is provided with at least 2 pin-and-holes.
The inner sleeve of described horizontal support leg also is with the horizontal support leg outer tube that vertically has a plurality of pin-and-holes outward.
The described scope that means 2 to 4 root posts of nearly bulkhead near bulkhead place or described periphery.
Be provided with the two groups of symmetrical U templates in front and back at the crossbeam of said each aspect of workplatform or the end of longeron, have circular hole on this U template, and be provided with two thru-bolts up and down, the telescopic girder of described square-section slides in said 4 thru-bolts.
Compared with prior art, the beneficial effect of the utility model is following:
(1) because the inner sleeve of vertical support leg, diagonal ligament leg and horizontal support leg all offers a plurality of pin-and-holes; Can pass through the relative position of the inner sleeve of change column, crossbeam or longeron and supporting leg; Realize the coarse adjustment function of supporting leg; The base of supporting leg both can have been supportted on interior bulkhead, also can support on inferior thermal insulation layer and main thermal insulation layer.When there is erection work the supporting leg below, liftable part supporting leg, installation can be placed on the thermal insulation layer of differing heights after finishing.
(2) because nut is installed with handle outward, can pass through turning handle, the double-screw bolt on the change supporting leg and the relative position of nut, the fine adjustment function of realization supporting leg makes base and interior bulkhead or thermal insulation layer closed contact.
(3) because the top horizontal direction of diagonal ligament leg outer tube is provided with at least 2 pin-and-holes; Can be through changing the relative position with the top horizontal direction pin-and-hole of track and diagonal ligament leg outer tube below the crossbeam of the lower inclined plane end of the side of the ground floor of larboard or starboard and the second layer, base and the interior bulkhead or the thermal insulation layer closed contact of realization diagonal ligament leg.Play supplemental support and rock-steady structure effect simultaneously.
(4) make the whole erection platform under situation about need not remove, can accomplish the erection work of 2 layers of thermal insulation layer in the cargo hold in the above.
