Description
Technical field
The present invention relates to the suspender of pipe laying deck crane, particularly relate to the Double-pipe hanger of pipe laying deck crane.
Background technology
Suspender refers in elevator machinery the device hanging and get weight, is widely used in hoisting and hanging industry.What commonly use in suspender is the Chained lifting appliances such as suspension hook.Hoisting suction cup, clamp and pallet fork etc. can use for a long time as special hanger on hoisting crane, also can be used as removable auxiliary lifting appliance and hang over Interim use on suspension hook, be usually used in many cargo types warehouse and stockyard, to improve operating efficiency.The suspender capturing bulk material is generally jaw grab bucket to be opened/closed, and also electromagnetic sucker is drawn as magnet conductivity materials such as boringss.Hang conventional the having of suspender of getting flowable materials to contain bucket and cage, generally by canting or take out the modes such as bottom plug and draw off molten steel or chemical solution, drawing off the flowable materials such as cement concrete by opening cage bottom door.
Suspender mainly contains Chained lifting appliance, forcipated sling, hoisting suction cup etc.Chained lifting appliance is made up of annexes such as chain sling and suspension ring, suspension hook, suspender belts, is a kind of metallic ropes tool, 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 higher, and the chain load-carrying capacity of same specification is higher.Its advantage: load-carrying capacity is high; 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; Serviceability temperature scope is large; Be easy to detect, convenient and swift.Its shortcoming: price is higher compared with suspender belt, steel rope; Conduct oneself with dignity bigger than normal.
Forcipated sling typically refers to clamp, for clamping, fastening, or the instrument of lifting.Hoisting suction cup is the suspender utilizing magnetic force or air pressure difference to draw weight, is divided into magnetic chuck and vacuum cup two kinds.
Suspender can also be applied in welding production, weld assembly will come and go handling between station, the operation such as also will carry out the upset of parts, in place, dispersion or concentrate, adopts welding equipment suspender to boost productivity, saves man-hour, alleviates 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 integrated sling forms by hanging pawl, pressing plate, bearing pin and hanger.Magnetic hoist is then divided into magneto, and (magnetic weakens gradually, discharging is slower, can not burst accident be there is), (magnetic force is comparatively strong, discharging convenient for electromagnetic type, easily there is burst accident during power-off) and permanent magnetism-electromagnetic type suspender (safe and reliable, without the need to worrying that current"on"time is short because having a power failure and other apparatus failures and workpiece occurs fall and cause personal injury equipment breakdown, power saving, consumption of current is few, is a kind of energy-saving safe suspender).And vacuum lifting tool is operationally rely on vacuum pump will to be evacuated in sucker absorption workpiece, because suction is limited, be mainly used in the thin plate that handling surfacing, weight are little.Except above-mentioned suspender, welded structure workshop is requisite also has some weight-hauling equipmenies, as ground means of transportation, elevator machinery class, conveyer etc.
Container spreader is the special tool of loading and unloading container, usually and the handling equipment such as shore container crane, tyred container door type crane, rail-mounted gantry container crane, freight container straddle type transportation vehicle and span winch with the use of.It has the structure adapted with container body, to be connected to carry out lifting effect by twist lock with the case corner fittings of casing.
Traditional pipelaying vessel steel pipe lifting tool single can only lift by crane a steel pipe, and efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of Double-pipe hanger, single can lift by crane two steel pipes, can greatly promote pipe laying efficiency.

According to an embodiment of Double-pipe hanger of the present invention, telescoping mechanism comprises: telescopic girder structure, telescopic oil cylinder, bassoon bearing pin, tubule bearing pin, ejector pin device.
According to an embodiment of Double-pipe hanger of the present invention, bassoon bearing pin, tubule bearing pin are arranged on telescopic girder structure, the movement of horizontal direction is carried out in driving by telescopic oil cylinder, until Steel pipe end surface touches ejector pin device, and ejector pin device top is put down, limit switch now in ejector pin device sends flexible danger signal, and expanding-contracting action stops.
According to an embodiment of Double-pipe hanger of the present invention, main beam structure is welding structural element.
According to an embodiment of Double-pipe hanger of the present invention, middle lifting-point device comprises: ring gear hook, HM Hydraulic Motor, driven wheel, ring gear hook mechanism, oil cylinder; Ring gear hook is arranged in ring gear hook mechanism, is connected with HM Hydraulic Motor, by the rotation of fluid motor-driven ring gear hook; Oil cylinder is connected with ring gear hook structure, controls the lifting action of whole ring gear hook mechanism.
According to an embodiment of Double-pipe hanger of the present invention, support roller device comprises: carrying roller and carrier roller frame.
According to an embodiment of Double-pipe hanger of the present invention, carrying roller is contained on carrier roller frame, carrier roller frame is connected with main beam structure, middle reserved certain interval, when suspender is fallen on steel pipe, carrying roller touches steel pipe, can change the gap between carrier roller frame and main beam structure, inhibiting device on main beam structure senses signal, and suspender just stops declining.
The present invention contrasts prior art following beneficial effect: the Double-pipe hanger that the solution of the present invention is made up of telescoping mechanism, main beam structure, middle lifting-point device and support roller device, the outer wall of opposite side steel pipe is fixed by middle lifting-point device, thus lifting two steel pipes, solve the problem that conventional steel suspender can only lift by crane a steel pipe.
