Description
Technical field
The invention belongs to elevator machinery, relate to a kind of rough terrain wheeled crane.
Background technology
Rough terrain wheeled crane mainly is used in narrow and small construction sites, building ground such as airport, oil field, harbour, harbour, warehouse.It is mobile convenient reliable to require hoisting crane to handle, and turn radius is little, from heavy and light, and good off-road capability, good lifting performance and higher intensity and rigidity.But, the structure keystone configuration of rough terrain wheeled crane is characterized as in the market: 1, car load travels and adopts mechanical drive mode to drive, power is passed to by transmission shaft on the drive axle of front and back through tor-con, change speed gear box, auxiliary gear box from driving engine again, power is passed on the wheel reduction gear by semiaxis through main reduction gear again, finish the car load driving of travelling.Make chassis structure become complicated, the car load deadweight increases, and energy consumption increases.2, linear crane arm often needs to stretch crane arm longer at the harbour, when harbour, warehouse and other special operation condition operation, or adjusts job position repeatedly, to satisfy the operation needs, has reduced operating efficiency.3, oleo-pneumatic suspension system or steel spring cooperate suspension with the locking hydraulic ram, need to increase separately pilot piping and respective valve group, increased and controlled complexity, hydraulic ram locking the time is subjected to that the influence of each steel spring self rigidity is difficult to realize that locking is balanced, and it is relatively poor that band carries when travelling whole vehicle stability.4, " H " shape telescopic outrigger, at the harbour, narrow and small construction site, building ground such as harbour, warehouse, performance of operating condition is relatively poor.
Summary of the invention
The objective of the invention is the deficiency that exists at above-mentioned existing structure and provide a kind of rational in infrastructure, manipulation, operation convenient and reliable, energy-conservation, be suitable for the rough terrain wheeled crane of narrow and small construction site operation.
Rough terrain wheeled crane everything of the present invention all adopts full hydraulic drive.
The present invention includes the lifting partial sum of the getting on the bus chassis of travelling of getting off.The lifting of getting on the bus partly comprises the arc crane arm, has control cabin, amplitude oil cylinder, turntable, the lifting mechanism of operator's compartment function and is positioned at crane arm in-to-in telescoping mechanism; The get off chassis of travelling comprises and whole box-shaped enclosed construction underframe and " X " shape telescopic outrigger also comprises the intelligent electrohydraulic control system of being made up of low speed high torque hydraulic motor and multi-joint Hydraulic Pump.Multi-joint Hydraulic Pump is the low speed high torque hydraulic motor that media drive is installed on forward and backward drive axle end with hydraulic oil, thereby realizes travelling of car load.
Crane arm of the present invention is the arc crane arm, this crane arm is made up of the mutual socket of a plurality of single-units, each single-unit comprises left side plate and cover plate up and down, left side plate is at the short transverse camber, cover plate is at the thickness direction camber up and down, left side plate and up and down cover plate along edges of boards along to be welded together to form the cross section be rectangle, profile is the tubular structure of arc.The arc crane arm is stressed good when operation, under the special operation condition, can make full use of the space, and operating turnaround is shortened, and operating efficiency is higher.
Control cabin of the present invention is fixed on the left side of turntable with the function of operator's compartment, makes the operator's compartment broad view.Establish instrument desk, steering handwheel, electric control handle, adjustable seat, heating and fridge equipment etc. in it, handle comfortable generous, safe and efficient.
Underframe of the present invention is whole box-type enclosed construction, whole box-shaped enclosed construction underframe guarantee hoisting crane uneven road conditions travel and any operation operating mode under have good intensity and rigidity.
Four telescopic outriggers of the present invention are respectively with its axis and the underframe axis is angled is fixed on the underframe, overlook direction and be " X " shape layout, wherein two are fixed on the bottom of underframe and lay respectively at the underframe both ends, in addition two are stretched into underframe middle part, its axis and the angled underframe two ends that are fixed on of preceding two axis from side, underframe two ends.The two telescopic outrigger axis that promptly are fixed on two ends, underframe bottom are parallel to each other, and the two telescopic outrigger axis that stretch into the underframe middle part from side, underframe two ends are parallel to each other.The movable supporting legs case is flexible realizes that by built-in supporting leg telescopic oil cylinder its stroke is decided by different operating modes, and is convenient and swift when making operation, stressed good, has good performance of operating condition.
There are three kinds of type of drive on the chassis of travelling of the present invention: front-wheel, trailing wheel and four wheel drive, the switching of three kinds of type of drive is by the valve group control that is installed between multi-joint Hydraulic Pump and the low speed high torque hydraulic motor.When on the smooth-riding surface, travelling, switch to two-wheel drive, switch to four wheel drive when injustice, abominable road traveling.Give full play to engine power performance and improved fuel economy, saved the energy.
Wheel steering of the present invention has four kinds of modes: front-wheel steering, rear-axle steering, crab row turn to, four-wheel steering, and the mutual switching of four kinds of steering modes is by the steering hydraulic oil cylinder and the control of the valve group between the multi-joint Hydraulic Pump that are installed on the forward and backward drive axle housing.The working space is narrow and small or changeablely when the operation of gradient place make hoisting crane operating mode comformability stronger for four-wheel steering or crab row turns to, and when giving full play to engine power performance, and has improved fuel economy, has saved the energy.
Forward and backward drive axle of the present invention makes hoisting crane car load when load is travelled have higher stability and reliability by special carrier and described underframe direct connection together.
Advantage of the present invention is: everything adopts full hydraulic drive, can realize stepless changes and velocity-stabilization according to different operating modes, impacts for a short time, and the chassis arranges that simply complete vehicle weight is light, handles convenient safe and reliable.Have and to realize electrohydraulic control system that multiple type of drive and steering mode switch mutually and driving, steering hardware fast, make turn radius little, can give full play to engine power performance and improve fuel economy, energy savings.Adopt dedicated integral box-shaped enclosed construction underframe, independently rigid suspended, the arc crane arm, " X " shape telescopic outrigger makes car load travel, have during operation good off-road capability, mechanical property, the adaptability for working condition energy, easy to maintenance, be particularly suitable for narrow and small construction sites, building ground such as airport, oil field, harbour, harbour, warehouse.
