Description

A kind of based on slip the self-contained complete-loading-unloading vehicle with the car hoisting device
Technical field
The present invention relates to a kind of special transportation vehicle that integrates lifting, handling, transportation function, be specially a kind of based on slip the self-contained complete-loading-unloading vehicle with the car hoisting device.
Background technology
Current whole self-loading and unloading vehicle has two series products:
The chief component of first kind product and function as shown in Figure 1, can realize the bulk handling operation of Standard pallet freight container, meet the requirement of special transportation vehicle Self-loading & self-unloading function, also can carry out hoisting operation in afterbody subrange class; Yet hoisting weight and the scope of work of the Self-loading-unloading mechanism 3 of first kind product are smaller, can't meet loose unpacked material and be lifted into Standard pallet from ground, or be lifted into the job requirements on ground from Standard pallet.
The chief component of Equations of The Second Kind product and function are as shown in Figure 2, on the whole self-loading and unloading vehicle of an above-mentioned class, reequip, increase a fixed type with car hoisting device 7, possess two cover equipment specials (with car hoisting device 7 and Self-loading-unloading mechanism 3), can realize lifting, handling, transportation function.Yet, the fixed type of Equations of The Second Kind product is with car hoisting device 7+ Self-loading-unloading mechanism 3 integrated modes, adopt fixed type with car hoisting device 7, be arranged in the front portion of vehicle, hoisting moment with the car hoisting device is larger, and mechanism's redundancy, cause the transport trolley deadweight larger, affected the carrying capacity of transport vehicle; Cost of product is relatively high, less economical.
Summary of the invention
In order to overcome existing self-contained complete-loading-unloading vehicle, exist the loading and unloading operation scope little, the deficiency that car load carrying capacity is not high, the present invention aim to provide a kind of based on slip the self-contained complete-loading-unloading vehicle with the car hoisting device, this self-contained complete-loading-unloading vehicle will be designed to slideable structure with the car hoisting device, can effectively enlarge the loading and unloading operation scope of self-contained complete-loading-unloading vehicle, improve delivery power.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of based on slip the self-contained complete-loading-unloading vehicle with the car hoisting device, comprise chassis, subframe, be contained on subframe with the car hoisting device, and pallet; Its constructional feature is that described subframe is provided with guide rail along its length, is positioned at the described of subframe front portion and can moves back and forth along guide rail under the driving of an actuating device with the car hoisting device.
Be below the technical scheme of further improvement of the present invention:
As a kind of concrete version, the described slipping base be contained on described guide rail that comprises with the car hoisting device, the revolution be contained on this slipping base is supported, and is contained in the horizontally rotated bearing that this revolution is supported; Be hinged with bracing frame on described bearing, on this bracing frame, be hinged with folding arm, on this folding arm, telescopic boom is housed, suspension hook is equipped with in the outer end of described telescopic boom; Described folding arm and telescopic boom form Collapsible structure; Between described bearing and bracing frame, between bracing frame and folding arm and be equipped with the driving telescopic oil cylinder between folding arm and telescopic boom.
Described oil cylinder is preferably scalable oil cylinder, particularly, between bearing and bracing frame, is support cylinder, between bracing frame and folding arm, is the folding arm oil cylinder, between folding arm and telescopic boom, is telescopic oil cylinder.
In order to provide support when self-contained whole the unloading more easily, the afterbody of described subframe is provided with horizontal support legs, and the end of this horizontal support legs is provided with telescopic vertical leg.Further, described horizontal support legs is telescopic loop bar.
As a concrete drive form, described actuating device comprises CD-ROM drive motor, and this CD-ROM drive motor is by sprocket wheel and chain drive is described with the car hoisting device, moves back and forth.
Certainly, the feasible drive form as another kind, described actuating device comprises hydraulic ram, the cylinder barrel of this hydraulic ram is connected with the car hoisting device with described; The latch stay bearing plate is housed on described subframe, the latch driven with the car hoisting device is housed on stay bearing plate.
For convenient, with the car hoisting device, with actuating device, be connected, described slipping base bottom is provided with the driving Connection Block be connected with actuating device, between this slipping base and guide rail, is provided with slider roller, can reduce the resistance of taxing with the car hoisting device.
In order to improve the rigidity of structure of subframe, described subframe is box-structure or channel-section steel unitized construction.
In order easily pallet to be drawn to subframe, on described subframe, track adjusting wheel is housed, described tray bottom is provided with guide frame, plays position-limiting action simultaneously.
As a kind of concrete version, at least 25% of described telescopic boom length is overlapped on described folding arm.
Compared with prior art, the invention has the beneficial effects as follows:
1. the present invention takes into account hoisting function and self-loading and self-unloading functions, and expands hoisting function.Existing product can Self-loading-unloading, but can only be in limited scope lifting operation, inconvenient to Standard pallet lifting loose unpacked material, the present invention can Self-loading-unloading with the car hoisting device by slippage, can also conveniently realize to the operation of Standard pallet lifting loose unpacked material;
The present invention little with hoisting moment with the car hoisting device replace hoisting moment large with the car hoisting device, car load is from heavy and light.Existing product adopts increases a set of large fixed random car hoisting device, and hoisting moment is large, and Heavy Weight causes car load large from weight, and transport capacity is little; The present invention utilizes slippage with the car hoisting device, can with little tonnage realize the hoisting operation of the large ton of fixed type with the car hoisting device with the car hoisting device, complete vehicle weight is light, transport capacity can improve greatly.
3. cost is low, good economy performance.The relatively current existing Equations of The Second Kind product of the present invention, replace two covering devices (fixed type is with car hoisting device+Self-loading-unloading device) with a covering device (slippage is with the car hoisting device), possesses very large cost advantage, and economic benefit is obvious.
