Description

The invention relates to manually driven vehicles, in particular to uniaxial hand trucks, and is intended mainly for snow removal, and can also be used for cleaning garbage and other bulk cargoes.

Known hand truck containing a horizontal axis with wheels, a body mounted on it and a handle (a.s. RU No. 1736800, B62B 1/12, publ. 05/30/1992), as well as known hand-held snow carts containing running wheels, a trolley body mounted on them and a U-shaped handle (CN patent No. 2773165, E01H 5/02, 09/13/2004; US patent No. 6735887, E01H 5/02, 05/18/2004).

All of these designs have several disadvantages. The weight of the transported cargo should be compensated by the weight of the working person, which leads to a decrease in the volume of transported cargo and to a decrease in labor productivity. The placement of the hands of the worker on the handle does not allow the maximum use of the applied physical effort due to the inconvenience of their location. When unloading cargo, it is necessary to lift the trolley, i.e. apply a lot of physical effort.

An object of the invention is to increase operational characteristics and increase productivity when working with a hand truck.

The technical result of the use of a manual truck-tipper is to increase usability, reducing the applied physical effort.

The specified technical result is achieved due to the fact that the hand truck-dump truck contains running wheels, the body of the truck and the U-shaped handle, moreover, two box-shaped guides are installed on the bottom of the body, having through holes in the lower part for hinging the handle, and in the upper part connected by a cross-member, which together form a frame that gives rigidity to the underbody of the truck. A rectangular boss with a through hole is fixed on the top of each rail. In the guides installed, with the possibility of movement, a U-shaped handle. The upper part of the handle has an arcuate shape and is bent towards the body of the trolley. This shape of the handle allows you to conveniently position the hands of a working person, as a result of which the applied force is used to the maximum. The lower part of the handle is a two frame structure of a triangular shape. At one of the vertices of each triangle there is a cylindrical boss with a through hole, each of which is installed in the corresponding body guide, with the possibility of interaction of the boss hole with the holes of the lower part of the guide through the axis. The second vertices of the triangles are interconnected by an axis on which the running wheels are mounted. In the middle part of the handle, at the place of its exit from the guides, with the possibility of movement, a latch is installed, made in the form of two cylindrical parts, worn on the vertical parts of the handle and connected by a transverse crossbar, and on each cylindrical part a fixing element is fixed in the form of a pin with a cone end. The conical ends of the pins have the ability to interact with the corresponding holes of the rectangular bosses mounted on the rails, and to fix the position of the body of the trolley relative to the handle. Two stops with inclined surfaces are also installed on the cross member of the body frame, designed to shift the latch up when the trolley returns to its original position. Running wheels, if necessary, can be replaced by runners.

Figure 1 shows a tipper truck, side view; in Fig 2 - truck tipper, rear view; in Fig 3 - the lower part of the handle; in Fig 4 - the lower part of the guides of the truck; figure 5 - handle lock; figure 6 is an embodiment of a trolley with runners, side view; Fig.7 is an embodiment of a trolley with runners, rear view.

The tipper truck consists of a body 1, on which two box-shaped guides 2 are connected, connected by a cross-beam 3. There is a through hole 4 in the lower part of each guide, and rectangular bosses 5 with holes 6 are installed on the upper part of each guide. In the guides 2, with the ability to move, a U-shaped handle 7 is installed with an arcuately bent upper part. The lower part of the handle 7 is made in the form of two frame triangular structures 8. In one of the vertices of each there is a cylindrical boss 9 with an opening, which are installed in the guides 2 and interact with the holes 4 through the axis 10. The second vertices of the triangles 8 are connected by an axis 11 on which are mounted running wheels 12. In the middle part of the handle 7, with the possibility of movement, a latch 13 is installed, made in the form of two cylindrical parts 14, worn on the vertical parts of the handle 7 and connected by a transverse switch Dina 15. Each cylindrical member 14 is fixed retaining element 16 in the form of a pin with a conical end. The conical ends of the pins 16 are able to interact with the corresponding holes 6 of the rectangular bosses 5 mounted on the guides 2. On the cross member 3 of the body frame are two stops 17 with inclined surfaces 18. The driving wheels 12, if necessary, can be replaced by skids 19. The front wall of the body 1 trolley is made at a slight angle to the horizontal surface.

Dump truck works as follows.

In the initial position, the latch 13 is in the closed position, i.e. the cylindrical parts 14 are closely adjacent to the guides 2 and the locking elements 16 are inserted into the holes 6 of the rectangular bosses 5, thereby fixing the position of the trolley body 1 relative to the handle 7. Moving the trolley forward by the handle 7, the body 1 is filled with snow. A truck filled with snow is lifted to the required level and transported to the place of unloading, while the shape of the handle 7 allows you to economically use the physical effort of a person. To unload snow from the body 1, lower the trolley to the loading position, move the latch 13 upward along the vertical parts of the handle 7. In this case, the locking elements 16 come out of the holes 6 of the rectangular bosses 5 and release the guides 2 from engagement. Then lower the handle 7 down. Under the influence of gravity of snow, the truck body rotates on the axes 10, dropping snow. Then the body 1 lowers to its original position and is fixed by the latch 13. To displace the latch 13 when returning to its original position, stops 17 are provided, the inclined surfaces 18 of which, due to their interaction with the crossbar 15, allow the handle 7 to be smoothly installed in the guides 2. When working on snow instead of the running wheels 12 can be installed runners 19.
