Technical field
The invention belongs to transporting heavy things equipment technical field, relate to a kind of load transport vehicle, particularly a kind of transporting heavy things go-cart, described weight refers to that length or volume are comparatively large, and heavier weight, can be such as the metal cylinder such as oxygen bottle.
Background technology
The assembling processing of steel tower all be unable to do without the welding of angle steel; and welding technique will use some protection gas, metal cylinder, as the major storage device of protection gas, just transports because welding the change in place unavoidably; but metal cylinder weight is comparatively large, carrying want two even three people could complete.
A lot of industrial and mining enterprises often adopt go-cart to carry metal cylinder at present, and these go-carts need manpower to complete following two basic operations usually:
The first, go-cart is pushed into metal cylinder lay down location, then metal cylinder is removed in go-cart;
The second, rotate go-cart, keep go-cart to balance and promote go-cart advancing.
Although metal cylinder transports essentially by go-cart, most of manpower can be avoided to move the situation of metal cylinder, but these two basic operation processes need to move metal cylinder equally, and except promoting go-cart advance, also need the extra power that maintenance go-cart balance is provided, therefore still waste time and energy on the whole.
Summary of the invention
As described in the background section, common weight go-cart still inevitably needs first to be removed by weight in go-cart, and from the design of current various go-cart, for maintaining the stationarity that go-cart is carried out, be in go-cart foremost be not often weight receiving structure in go-cart, therefore, even if by go-cart near weight, still there is certain distance with weight.Step in go-cart is moved in order to exempt weight, save labour power, the present invention advises that the stop portions of part obstructs between weight and weight receiving structure (being often in go-cart foremost) is removed or bending by go-cart when weight, make weight receiving structure more near weight, but in stop portions bending or after removing (obviously with bending, there is the effect of similar change go-cart center of gravity), the center of gravity of whole go-cart probably shifts, and weight receiving structure can meet accident because of crank when receiving weight.
A technical problem underlying to be solved by this invention is exactly after go-cart stop portions bends or removes, and go-cart weight receiving structure receives the problem that can meet accident because mass centre changing is unstable during weight.

Detailed description of the invention
This detailed description of the invention is supplementing and describing in detail summary of the invention part.
A kind of load transport vehicle of summary of the invention introduction, this load transport vehicle comprises frame body and bearing base, to realize the rotation of bearing base in frame body and at least to make bearing base and frame body geo-stationary by clutch part when needed, on this basis, the present invention optimizes further further by three aspects.
One, the optimization that manpower is paid is saved further
For metal cylinder, blue gas in bottle number can affect the center of gravity of metal cylinder, therefore, for the metal cylinder of different center of gravity, loaded and transported on bearing base, to go to the manpower paid of carrying position completely different from connecing object location for bearing base, need to adjust the turning cylinder of bearing base relative frame body, the technical scheme that the present invention provides makes described rotating element comprise the tumbler being rotationally connected frame body and bearing base, be fixed on the moving member that tumbler also at least slides on bearing base and the slide control parts regulating moving member sliding distance on bearing base.
Moving member moving relative to bearing base, can have two kinds of situations: the first, bearing base is fixed, and moving member moves; The second, moving member is fixed, and bearing base moves.When moving member moves relative to bearing base, only moving member is moved, the present invention has set up the slip position of sliding for moving member in described frame body, thus moving member can slide on slip position, in addition, described rotating element also comprises the positioning element be positioned at by moving member respectively in bearing base and frame body, and when positioning element is unclamped, moving member slides on bearing base and frame body; During positioning element location, moving member is fixed in bearing base and frame body.When those skilled in the art need to change the position of tumbler, unclamp positioning element, and rotate bearing base, bearing base and frame body are maintained an equal level, thus moving member can be made to slide on bearing base and frame body simultaneously, mix up the position of moving member, and then with positioning element, moving member is located, moving member is fixed in bearing base and frame body.
When bearing base relative movable parts moves, only bearing base is moved, to I haven't seen you for ages, the extensible member in clutch part and abutment are separated from each other like this, clutch part is made to lose clutch function to bearing base and frame body, for this reason, rotating element of the present invention also comprise fixing on the clutch partner and the clutch part moving member at least slided in frame body.Clutch part moving member along with bearing base synchronizing moving, and can adopt the registration device identical or similar with described positioning element to position clutch part moving member.
