Description

113

The invention relates to a lifting and construction machinery industry and can be used for loading components in concrete mixers.

The aim of the invention is to increase the efficiency of use of the hoist by eliminating special loading means.

Fig. 1 shows a skip hoist at the time of opening, section A-A; figure 2 - skip in the lower position, the node I; on fig.Z - closed skip in the upper position.

The lift consists of a skip made of a fixed and movable sections 1 and 2, an additional curvilinear guide 3, rigidly connected to the fixed section 1, a disclosure mechanism in the form of a bracket 4 fixed on the lower guides 5, the upper guide 6, additional rollers 7 mounted on section 2.

Section I and 2 are connected at the top of the levers 8.

The skip can be equipped with a locking mechanism for closing the sections of an unloaded skip. Clamps 9 are provided for fixing section .2 to guide 3.

The lift works as follows.

After the skip is immersed in the bulk material with the help of a traction rope 10, the skip closes and simultaneously sets the material. In order not to lift the unloaded skip, the blocking is performed, for example, in the form of two axcentric 11s mounted on the axis, which under the action of the spring are pressed to the guide 6. The eccentrics 1 1 move away from the guide 6 only when the ski7 is completely closed

na by pressing the stops of section 2 on the reverse end of the eccentric 1I. For a straight line, so that 7 can be freely sewn up along the upper edge of the bracket 4, use hinged half-turn sections 12,

which are turned when the rollers 7 are pressed from below. After the skip passes, the areas 12 under the action of their own weight are lowered onto the stops. The rear rollers 13 of the skip pass direction 6 up and then roll along the top shelf of the guide 5, along which the front rollers 14 roll.

Claims (2)

1. A lift, including a skip with front and rear rollers, upper and lower guides, characterized in that, in order to increase the efficiency of use by eliminating special loading means, the skip is performed from the movable and stationary sections and is equipped with a mechanism for opening them in the form of a bracket mounted on the lower guides, an additional curvilinear guide and additional rollers, while the front and rear rollers are mounted on the fixed skip section and the additional rollers on its movable section, and the additional curvilinear guide is rigidly connected to the fixed section of the skip, and the movable section of the skip is mounted for movement along the additional curvilinear guide and along the upper edge of the mechanism for opening the sections when interacting with additional rollers. 2. A lift according to Clause I., of tl and - due to the fact that it is equipped locking mechanism for closing sections of an unloaded skip.
