Description
Technical field
The utility model relates to a kind of platform single armed cantilever beam, belongs to the ocean engineering mechanical field.
Background technology
Design-calculated platform cantilever beam was generally twin beams (also claiming both arms) structure in the past, and its cantilever beam platform overlap joint is between two cantilever beams, and cantilever beam lower end and track form bearing fit.The cantilever Liangqi track of this twin-spar construction mainly satisfies level and gets final product with sliding to spacing; Simplicity of design; And have good stability, but have following problem at the cantilever beam of the last twin-spar construction of platform (area is limited): the one, it is big, big with steel liquid to account for area, accounts for the platform area more than 60% than the single armed cantilever beam at least more; Thereby cause the flat-bed usable floor area to increase, and the structural area of whole flat strengthen; The 2nd, the cantilever beam of employing twin-spar construction, it uses steel more than 40% than the single armed cantilever beam at least; Thereby cause flat-bed to strengthen, drawbacks such as fabrication cost height with steel material.But simply make twin beams overarm arm into the single-beam cantilever beam, because in platform uses, the effective combination and stability, safety issue that need overcome load is big, the platform swing causes overarm arm and guide rail.
Summary of the invention
The purpose of the utility model is exactly the problem that exists to prior art, proposes that a kind of floor area is little, consumptive material is few, and has the platform single armed cantilever beam of good stable property and safety.
Its technical scheme comprises: the slide rail of cantilever beam and cantilever beam bearing fit, wherein cantilever beam is to be fixed with the cantilever beam deck at the top of vertical mainboard.Be " protruding " shape structure behind the vertical mainboard bottom level cantilever mounted beam seat plate of cantilever beam, vertical mainboard be by about two parallel riser upper and lower sides captive joint with the cantilever beam seat board with the cantilever beam deck respectively and constitute; Slide rail is to be captiveed joint with base plate by the baffle plate bottom of the left and right sides, and constitutes " protruding " connected in star structure that cooperates with overarm arm bottom behind the fixed guide piece respectively on the top of baffle plate.
Left and right end portions at the cantilever beam seat board upwards is fixed with slide block respectively, and the orienting lug on slide block and top forms bearing fit.
Base plate bottom at slide rail is fixed with stay bearing plate, is fixed with baffle plate bracket and orienting lug bracket respectively in the baffle plate and the orienting lug outside of both sides.
Fixed interval has strut member between the vertical plates on both sides of cantilever beam and cantilever beam deck, is fixed with the riser bracket respectively in the riser outside of cantilever beam.
The beneficial effect of the utility model is: be improved to the cantilever beam of single-spar construction by the cantilever beam of original twin-spar construction, realized taking that the platform area is little, in light weight, cost is low, practical; Improvement through to the combination of cantilever beam and slide rail has realized the spacing cooperation of upper and lower, left and right, has improved the stability and the safety of operation before and after the overarm arm; Increased several left and right cantilever beam strut members,, saved the steel use amount, also under equal conditions reduced the fabrication cost of cantilever beam, reduced the investment that whole flat is built guaranteeing to carry under the prerequisite of intensity.
