Description

A kind of manpower transport's car

Technical field

The utility model relates to a kind of transportation means, specifically is meant a kind of transport trolley.

Background technology

At present, rise the also proper special tool of neither one of a dead lift of oil drum and mechanical handing for 100-200, existing carrying force method township adopts a dead lift or carries with hand barrow, all there are many shortcoming and defect in these two kinds of methods, be in particular in: because the oil drum volume is bigger, weight is big, a dead lift is wasted time and energy, labour intensity is big: with traditional hand barrow carrying, because the body gravity height, oil drum mostly is cylindrical shape in addition, instability during the oil drum carrying, be easy to roll, cause oil plant to reveal even oil plant collide in handling process and rolls and seriously safety misadventure such as combustion explosion takes place.In addition, load onto hand barrow with standing in oil drum on the ground, put down gently on the hand barrow if need to adopt oil drum to lift again, waste time and energy, labour intensity is big, and need many people to cooperate, efficient is low, if the oil drum cant that will stand is poured the enterprising luggage fortune of hand barrow into, then the process that reduces gradually in the oil drum center of gravity needs the workman supporting oil drum with hand always, prevent that it is tiltedly too fast, and with hand barrow generation sharp impacts, labour intensity is big, and efficient is low, in addition, when pouring the oil drum cant into hand barrow, often occur moving behind the hand barrow, make shipping work etc. carry out again, waste time and energy, equally, waste time and energy equally when the oil drum on the hand barrow is unloaded, labour intensity is big, therefore, existing this hand barrow handling and loading oil drum is relatively required great effort and is bothered.In addition, the wheel of existing hand barrow can not lift adjustment, is difficult to adapt to different road conditions and actual needs, make troubles to the user,

The utility model content

The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of laborsaving light, and manpower transport's car of wheel height-adjustable.

For achieving the above object, the technical solution of the utility model be include vehicle frame and about two wheels, two wheel erecting frames that are symmetrically set about described vehicle frame includes, be set with strut bar respectively on these two wheel erecting frames, also include the goods spare that is arranged on the vehicle frame and accommodate mechanism and wheel height adjustment mechanism.By this setting, can carry out height adjustment to wheel neatly, on rugged road surface, wheel position suitably can be heightened, and smooth road surface can suitably be turned down wheel position, make that the hand barrow center of gravity is low, move stable, and laborsaving.

Further be provided with is that described wheel erecting frame is to be parallel to each other to erect two pivot shafts that fixedly install, be set with across plate between these two pivot shafts, two two wheel lifting mount pads that wheel is installed about described wheel height adjustment mechanism supplies, two slippage covers that this wheel lifting mount pad includes axis of wheel rotation and is fixedly set in two ends, the axis of wheel rotation left and right sides and joins with described pivot shaft slippage cover, described wheel lifting mount pad is arranged between two pivot shafts with respect to the below across plate, and this wheel lifting mount pad and across being connected with threaded column between the plate, the lower end of this threaded column and wheel lifting mount pad are fixedly connected, and its upper end is passed across plate and its and is provided with setting nut.By this setting, can carry out height adjustment to wheel neatly, on rugged road surface, wheel position suitably can be heightened, and smooth road surface can suitably be turned down wheel position, make that the hand barrow center of gravity is low, move stable, and laborsaving.

Further being provided with is also to comprise in stockit is available loading and unloading servomechanism, and this goods spare loading and unloading servomechanism is the arc stay bearing plate that two and every two ends are individually fixed in the lower end of the head end of strut bar and wheel erecting frame.This setting is by the arc stay bearing plate, and the ingenious lever principle of having utilized makes cargo handing lightly convenient, laborsaving, the efficient height.

Further be provided with is that described goods spare accommodates mechanism and includes the outer skid plate that sticks up of the head end that is arranged at strut bar and the upper limit mechanism that is arranged at the strut bar rear end.By this setting, when barrel handling, only need the utility model is stood on the limit of erectting the oil drum of placing, skid plate is inserted into oil drum, block the top of oil drum spacing by upper limit mechanism then, oil drum is positioned on the strut bar, then toward drop-down strut bar, at this moment, oil drum just can be along with strut bar falls down, the downdraw process of strut bar is to be support with the arc stay bearing plate, and therefore whole process is very mild and because lever principle and very laborsaving, in addition, relative displacement does not take place in whole process oil drum and barrel handling carrier described in the utility model, therefore, sharp impacts can not take place in oil drum and transport trolley, has solved the potential safety hazard of bringing because of collision in traditional oil drum handling process.The utility model not only can be used for oil drum, also is applicable to the carrying of all other similar articles certainly, only need load onto hopper on strut bar and get final product.

Further being provided with is that described arc stay bearing plate is 1/4 circular base slab.This setting can be so that the toppling process of oil drum be milder.

The head end that further setting is described two arc stay bearing plates is provided with the head end support beam.This setting not only can be strengthened the position of two arc stay bearing plates, and this head end support beam can cooperate skid plate that the bottom of oil drum is better supported, and makes oil drum be fixed on better on the barrel handling carrier described in the utility model in handling process.

Further being provided with is that described upper limit mechanism includes the movable sleeve pipe that is sheathed on the strut bar, is arranged at the positioning pawl of sleeve pipe front end, and this positioning pawl integral body is inverted "L" shaped.Because the upper end of the oil drum of standard is provided with and is protruding periphery setting, so this positioning pawl can directly be stuck on the protruding periphery, and the upper end of oil drum is fixed, and whole position fixing process is simple and convenient.Further being provided with is that indent is provided with the spring mounting hole that is used to install retracing spring on the described internal surface of sleeve pipe, and described strut bar fixedly installs the outer end spring perch with respect to the open end of the spring mounting hole of sleeve pipe.Because oil drum part plurality of specifications, this be provided with can be the utility model adapt to different size oil drum and with the upper end positioning and fixing of oil drum.

Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
