Description

Concrete handcart for building site
Technical Field
The invention relates to the field of building construction, in particular to a concrete trolley for a building site.
Background
Building site, yue language building ground, construction ground, for short ground, is a place where building projects are being developed to carry out civil engineering, and often the scope thereof is closed by coamings, wire netting or enclosing walls, and the access of personnel, materials, machinery and vehicles is limited.
Concrete, referred to as "concrete (t you ng)": the concrete is a general term for engineering composite materials formed by cementing aggregate into a whole by cementing materials, and the term of concrete generally refers to that cement is used as the cementing materials, and sand and stone are used as the aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water (which may contain additives and admixtures) according to a certain proportion and stirring, and is widely applied to civil engineering.
The handcart is a transport vehicle pushed and pulled by human power, which is the ancestor of all vehicles, although the technology of transporting materials of the handcart is continuously developed, the handcart is still used as an indispensable transport tool, and the handcart is widely applied in production and life because of low cost, simple maintenance, convenient operation and light dead weight, can work in places where motor vehicles are inconvenient to use, and is very convenient for transporting lighter objects in short distance.
When concrete is transported in domestic construction sites at present, the concrete is usually transported by a trolley, and due to the fact that manual transportation is conducted by manpower, the road surface of the construction site is uneven, and meanwhile the concrete is filled with fluid, the concrete is often spilled out of the trolley and falls on the ground when constructors transport the concrete by the trolley, the concrete falling on the ground cannot be normally used after being polluted, resources are wasted, and meanwhile, much inconvenience is brought to later-stage cleaning work; in addition, in the process of transporting concrete by the traditional handcart, due to the bumping of the road surface, gravels with higher density in the concrete move to the bottom of the handcart under the action of self gravity, so that the gravels and cement in the concrete are unevenly distributed; even a small number of handcart is inside to be provided with rabbling mechanism simultaneously, but adopt the motor to drive the puddler usually or drive the puddler through rotating the wheel and rotate, but both have great drawbacks, it needs the circular telegram to drive the puddler through the motor, all bring more inconvenience for constructor through battery powered or external power source during no matter, if use when rotating the wheel and driving the puddler rotation, because the concrete density is great, need make the puddler rotate and need constructor consume huge strength usually and move, the operating personnel of being not convenient for uses.

in the transportation process, due to the uneven ground of the construction site, a downhill road section and an uphill road section often occur, when the trolley is bumped, two ends of the balance plate 203 move along with the bumping, when the trolley encounters a downhill road section, the concrete inside the hopper 1 moves towards the outside of the hopper 1 due to the influence of the gradient, due to the granular solid matter contained inside the balance plate 203, the front end of the balance plate 203 moves downwards by taking the connecting block 214 as the center, so as to drive the fixture block 204 to move, the fixture block 204 moves to drive the first chain 205 to move, the first chain 205 moves to drive the first rotating rod 207 to rotate, so as to drive the second chain 208 to move, the second chain 208 moves to drive the first bevel gear 209 to rotate, so as to drive the second bevel gear 210 to rotate, the second bevel gear 210 rotates to drive the second rotating rod 211 to rotate, so as to cause the screw rod 212 to rotate, and the connecting hole drives the screw rod 604 to move upwards, the connecting sleeve 603 is driven to move upwards, the connecting sleeve 603 moves upwards to drive the first baffle 601 to move upwards, the first baffle 601 moves upwards to stop the concrete poured outwards from the hopper 1 back to the hopper, the loss of constructors to the concrete in the transportation engineering is reduced, and the difficulty of later-stage cleaning work is reduced;
when constructor transported the concrete to assigned position department through the handcart, constructor promoted the movable block 4 with the foot and moves to fixed cover 3 inside, after movable block 4 and kicking block 5 contacted mutually, movable block 4 drove kicking block 5 rebound, when movable block 4 removed when unable removal, the top of kicking block 5 was the vertical form with the bottom of balance plate 203, can empty the inside concrete of hopper through push rod 7, kicking block 5 carries on spacingly effectively to balance plate 203 and prevents when empting the concrete, elevating system 6 hinders the normal of concrete and emptys.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
