Description

Loading and unloading mechanism of transport vehicle

The utility model relates to a kind of transport vehicle and carries handing device, and it can be installed on truck body, semi-trailer or the special towed vehicle, load such as freight container, crate, hopper, machine, motor type equal-volume more greatly, heavier article.

Usually, when on lorry, semi-trailer or similar vehicle, loading above-mentioned large article, need special hoisting crane to load and unload, increased cost of transportation to the scene, and very not convenient.

The handing device that provides a kind of vehicle to carry is provided goal of the invention of the present utility model, it can be installed on the vehicle, so that the article loading that freight container is so bigger is to vehicles such as towed vehicle, and can unload from it, need not use any other handling equipment.

Goal of the invention of the present utility model is achieved in that installs one group of lifting and swinging device that is positioned at freight container or goods both sides on the vehicle body of transport vehicle or towed vehicle, its upper end has hanging apparatus, be used to lift freight container, its lower end connects with the fixed bearing axle, can swing around fixed bearing.Crossbeam place at chassis has the bearing cross beam device, in case body inclination in the hoisting process.When loading and unloading, the bearing cross beam device is supported on the ground of loading and unloading one side, and hanging apparatus is good with container fixing, then, the lifting of lifting and swinging device is with container lifting, swing to the position that to place again, freight container is placed, can finish the handling labor of freight container.

Below with reference to accompanying drawing the utility model is done and to be described in further detail.

Fig. 1 is the vehicle rear handing device scheme drawing of the utility model embodiment;

Fig. 2 and Fig. 3 are put into ground process scheme drawing for above-mentioned handing device unloads freight container;

Fig. 4 has provided freight container and has transferred to scheme drawing on another vehicle;

Fig. 5 is the view of above-mentioned handing device in transportation.

Referring to accompanying drawing 1.Freight container (2) is placed on the towed vehicle, and one group carries handing device and is arranged on the chassis (1) of freight container front and back end.The structure of front and back handing device is identical.The bearing cross beam device of this handing device is made up of fixed cross beam (6), flexible crossbeam (7), hydraulic ram supporting leg (8) and telescopic oil cylinder (15).The cross-sectional plane of fixed cross beam (6) is " mouth " font, by a pair of fixing in its lower section and can be supported on trailer along the roller (13) that track rolls longitudinally on the girder track.Flexible crossbeam (7) also is " mouth " shape structure, and it is sleeved in the fixed cross beam (6), forms " returning " font structure.Telescopic oil cylinder (15) is a single-piston, floating-caliper brake rod-type structure, and cylinder body end is captiveed joint with the rear end of fixed cross beam (6), and the front end and the yoke plate (14) of rod end and flexible crossbeam (7) are connected in parallel.The piston rod of telescopic oil cylinder (15) is flexible, and the push-and-pull crossbeam (7) that stretch stretches in fixed cross beam (6).Hydraulic ram supporting leg (8) is connected with the front end axle of flexible crossbeam (7) with yoke plate, and yoke plate (14) can move in the groove (19) of flexible crossbeam (7).When telescopic oil cylinder (15) promotes flexible crossbeam (7) when stretching out, promote yoke plate (14) and in groove, move, hydraulic ram supporting leg (8) rotates downwards thereupon.This supporting leg also is the single-piston, floating-caliper brake cylinder structure, and piston rod stretches out and can be supported on the ground; The piston rod withdrawal then spurs yoke plate (14), and drives oil cylinder supporting leg (8) rotation upwards, is state shown in Figure 5.

The lifting and swinging device is formed by having led arm (4), lifting arm (3) and master cylinder (5).The transversal surface of having led arm (4) is " mouth " font, on the bearing (12) that the bottom of its bottom and the master cylinder (5) of single-piston, floating-caliper brake rod-type structure is connected in pivot (11) hinge and the bottom surface of fixed cross beam (6) is welded as a whole.The rod end of master cylinder (5) with led arm (4) and be connected with hinge (16).When the piston rod of master cylinder (5) stretches out, make the master of accumbency play arm (4) and swing rise left around fixed bearing pivot (11); When piston rod was withdrawn, then right pendulum fell, and is horizontal.The lifting arm (3) that transversal surface is " mouth " font is sleeved on have been led in the arm (4), and its upper end is a lifting dish (9), and the chain sling (10) that two ends have suspension hook passes the lifting dish, and this suspension hook can insert in the lifting hole(eyelet) (17) under the freight container.Hoist cylinder (18) is a single-piston, floating-caliper brake rod-type oil cylinder, and cylinder body is connected with the bottom of having led arm (4), and rod end then is connected with lifting arm (3).The piston rod of hoist cylinder (18) and master cylinder (5) stretches out respectively, makes the lifting dish (9) on the lifting arm (3) be positioned at the container top center, and freight container is sling, and is state shown in Figure 2; The two shrinkage fit, freight container is placed into (see figure 3) on the desired position, ground the most at last.Otherwise, also ground container crane can be installed on the towed vehicle.

In addition, the utility model can also be realized freight container hung oneself from towed vehicle and transport on another and neat towed vehicle or platform, also the container crane on another car or the platform can be transported on this towed vehicle.In this case, flexible crossbeam (7) directly reaches on another towed vehicle flat board or on the platform table top, the hydraulic ram supporting leg pins, and still remains on vertical state, can handle by above-mentioned step.

This handing device that carries only needs one man operation, and another people assists to carry out the loading and unloading of freight container.Hydraulic efficiency power unit can drive Hydraulic Pump on request by the combustion engine of the driving engine of tractor truck or a small-sized separation or electrical motor and provide.

The handing device that carries of the present utility model, simple and reasonable for structure, vehicle is easy to carry, does not influence to load other strip shape goods, as timber, steel, cement pole etc.
