The invention adopts the technical scheme that the single pipe lifting appliance device comprises a telescoping mechanism, a girder structure and a carrier roller assembly, wherein the girder structure is respectively connected with the telescoping mechanism and the carrier roller assembly.
Description
Technical field
The present invention relates to the pipe laying deck crane, relate in particular to the single tube hoisting device at freight container handling exploitation.
Background technology
Suspender refers to hang the device of getting weight in the elevator machinery, is widely used in the hoisting and hanging industry.Commonly used in the suspender is chain type suspender such as suspension hook.Hoisting suction cup, clamp and pallet fork etc. can use as special hanger on hoisting crane for a long time, also can be used as removable auxiliary suspender and hang over use temporarily on the suspension hook, are usually used in many goods kind warehouse and stockyard, to improve operating efficiency.The suspender that grasps bulk material is generally jaw grab bucket to be opened/closed, and also available magnetic chuck is drawn as magnet conductivity materials such as boringss.Hang the suspender of getting flowable materials commonly used the bucket of Sheng and cage are arranged, generally by canting or take out mode such as bottom plug and draw off molten steel or chemical solution, draw off flowable materials such as cement concrete by opening the cage bottom door.
Suspender mainly contains chain type suspender, forcipated sling, hoisting suction cup etc.The chain type suspender is made up of annexes such as chain sling and suspension ring, suspension hook, suspender belts, is a kind of metal Current Collector Sleave, is divided into 60 grades of suspenders by load-carrying capacity, 80 grades of suspenders, 100 grades of suspenders and 120 grades of suspenders etc.Rank is more high, and the chain load-carrying capacity of same specification is more high.Its advantage: load-carrying capacity height; Safety is good, disrumpent feelings stretch ratio 〉=20%; Array configuration is various, and commonality, interchangeability are strong; Length is adjustable, be easy to deposit; Long service life; The serviceability temperature scope is big; Be easy to detect, convenient and swift.Its shortcoming: price is higher than suspender belt, steel rope; It is bigger than normal to conduct oneself with dignity.
Forcipated sling typically refers to clamp, is used for clamping, and is fastening, or the instrument of lifting.Hoisting suction cup is to utilize magnetic force or air pressure difference to draw the suspender of weight, is divided into two kinds of magnetic chuck and vacuum cups.
Container spreader is the special tool of loading and unloading container, and common and handling equipment such as shore container crane, tyred container door type crane, rail-mounted gantry container crane, freight container straddle type transport trolley and span winch are used.It has the structure that adapts with container body, is connected the effect of lifting by twist lock with the case corner fittings of casing.At present, be applied to the R﹠D and production of suspender of harbour running mainly at the freight container handling, by with the supporting handling that realizes freight container of various land handling appliances, but do seldom for the suspender in other field, the suspender field of application is single, has restricted the exploitation in market.Such as, suspender can also be applied in the welding production, weld assembly will come and go handling between station, also to carry out parts upset, in place, disperse or operation such as concentrate, adopt dress weldering suspender to increase productivity, save man-hour, alleviate bundle and hang operation intensity and safety in production.Such as, mechanical suspender is mainly used in the suspender of sheet material level lifting, and suspender uses in pairs, and whole suspender is formed by hanging pawl, pressing plate, bearing pin and hanger.The magnetic suspender then is divided into magneto, and (magnetic weakens gradually, discharging is slower, burst accident can not take place), (magnetic force is strong, discharging convenient for electromagnetic type, burst accident takes place easily during outage) and permanent magnetism-electromagnetic type suspender (safe and reliable, need not to worry because having a power failure and other apparatus failures workpiece takes place fall and cause the personal injury equipment breakdown, power saving, current"on"time is short, consumption of current is few, is a kind of energy-saving safe suspender).And the vacuum suspender time is to rely on the vacuum pump absorption workpiece that is evacuated in sucker in work, because suction is limited, is mainly used in handling surfacing, the little thin plate of weight.Except above-mentioned suspender, requisite some weight-hauling equipmenies in addition of welded structure workshop are as ground means of transportation, elevator machinery class, conveyer etc.
Summary of the invention
The objective of the invention is to address the above problem, a kind of single tube hoisting device be provided, can for hoist, steel tube place's usefulness on the mobile pipelaying vessel, promote the pipelaying vessel operating efficiency to greatest extent.
Technical scheme of the present invention is: the present invention has disclosed a kind of single tube hoisting device, comprises telescoping mechanism, main beam structure and idler assembly, and wherein main beam structure links to each other with idler assembly with telescoping mechanism respectively.
According to an embodiment of single tube hoisting device of the present invention, described telescoping mechanism comprises telescopic girder structure, telescopic oil cylinder, barrel bolt axle and ejector pin spare.
Embodiment according to single tube hoisting device of the present invention, the barrel bolt axle is installed in above the telescopic girder structure, rely on the driving of telescopic oil cylinder to carry out the movement of horizontal direction, touch ejector pin spare up to the steel pipe end face, and ejector pin spare top is flat, the limit switch in the ejector pin spare sends flexible danger signal so that expanding-contracting action stops at this moment.
According to an embodiment of single tube hoisting device of the present invention, idler assembly comprises carrying roller and carrier roller frame.
Embodiment according to single tube hoisting device of the present invention, carrying roller is installed on the carrier roller frame, carrier roller frame is connected with main beam structure and the middle gap of reserving, when suspender is fallen on the steel pipe, thereby carrying roller touches the gap between steel pipe change carrier roller frame and the main beam structure, and the inhibiting device on the main beam structure is sensed signal so that suspender stops to descend.
According to an embodiment of single tube hoisting device of the present invention, main beam structure is welding structural element.
The present invention contrasts prior art following beneficial effect: the solution of the present invention is that the single tube hoisting device is made of telescoping mechanism, main beam structure and idler assembly, and wherein main beam structure links to each other with idler assembly with telescoping mechanism respectively.Compared to conventional art, suspender of the present invention can enlarge market scope, can march maritime works market from machine market, port, has realized the diversification of the field of application of suspender, has improved the competitiveness of product in market.
