Description

This invention relates to vehicles for the transport of cylindrical loads.

Closest to the present invention is a handcart for transporting barrels, containing a frame mounted on wheels, equipped in the front part with clamps for the bottom of the transported drum on the swiveling axles, and an arched hook cap for tipping the transported barrel to the frame of the trolley 1.

However, such a cart makes it difficult to handle barrels with a capacity of 100–200 l in storage facilities and does not ensure their secure fixation during transportation.

The purpose of the invention is to improve the working conditions with the cart and increase its reliability.

This goal is achieved by the fact that in the handcart for transporting barrels containing a frame mounted on wheels, equipped in the front part with grips for the bottom of the transported drum on the swiveling axles, and an arbor-type closure cap for tipping the transported barrel into the trolley frame, the arcuate gripping is located perpendicular to the longitudinal axis of the carriage and connected to the frame by means of hangers, and the pivot axes of the claws under the bottom are connected to the frame by means of pivoting brackets equipped with glasses with lateral spiral slots, rotary axes are installed in the indicated glasses and equipped with pins entering the specified slots.

FIG. 1 - trolley shown, general view; in fig. 2 - capture under the bottom of the barrel; in fig. 3 - trolley in the initial position; in fig. 4 - the phase of the capture of the barrel; in fig. 5 — drum tipping phase; in fig. 6 - transport position of the cart with a barrel; in fig. 7 - the phase of capturing the barrel of a smaller size.

The cart is a welded frame 1 of pipes, mounted obliquely to the horizontal on three rubber wheels with rolling bearings.

The front two wheels are mounted on the same axis rigidly connected to the frame. The rear wheel rotates freely about the vertical axis on the support plates, the casing of which is also connected to the frame by means of a bracket.

The welded frame 1 is a lever for tipping and lifting the barrel and a supporting base for moving it; ...

The extension frame 2 is hinged to the welded frame 1 on the suspensions 3, the circular arcuate grip 4 is hinged on the fixed suspensions 5, the grips 6 are hinged on the swivel arms 7. The clamp 6 is a kinematic chain of composite links: cup 8 with a spiral slot, pivot axis 9. A pin 10 is mounted into the axis 9 through a slot. A bearing element 11, made of a strip metal along a broken broken curve line (like a screw one) and fixed by a cone 12, is mounted on the 39point of the axis 9. but directly at the barrel (Fig. 4, 7). With this, the axes 9 of the grips 6, abutted with the tips of the cones 12 on the floor (or the platform), rotate with the elements 11 in opposite directions. The ends of the elements 11 are moved apart by a distance corresponding to the size of the barrel. The grip 4 is thrown onto the barrel (Fig. 4). Then, using the frame of the cart, as a lever, the barrel is mounted on the "edge.

At this moment, the axles 9 lose their support points and, lowering under the action of the force of gravity, each turn in the opposite direction, oppositely. At the same time, the ends of the elements 11 come closer together, but already under the bottom of the barrel, by a distance significantly smaller than its diameter. This is how the barrel is seized from below (Fig. 5).

When the upper end of frame 1 is subsequently lowered relative to the support points of the front pair of wheels, the barrel rises and, in an inclined position, is placed on the support of the third wheel (Fig. 6). Then, a horizontal displacement thereof is effected. Lowering the barrel and installing it on the “butt end is the reverse process of lifting.

To lift and move the barrel with a capacity of 100 liters, the grippers on the turn brackets 7 are displaced in size and fixed. The suspenders 5 of the gripper 4 are lowered and also fixed (Fig. 7).
