Abstract

Usage: in construction, in particular when loading containers for evacuating soil from the production zone during the construction of underground structures by the method of lowering wells. SUMMARY OF THE INVENTION: the device comprises a support frame and a loading hopper mounted thereon. The hopper is mounted on the frame with the possibility of rotation around a horizontal axis, which is located below the center of gravity and offset relative to it towards the front wall of the hopper. Due to this, the hopper has the ability to automatically tip over and unload into the tank when passing the latter to the load. 1 ill.

Description

The invention relates to hoisting and transport machinery and can be used in construction, in particular, when loading containers, mainly skips, for evacuating soil from the production zone during the construction of underground structures by lowering wells.

A device for loading a skip is known, which comprises a loading hopper equipped with a shutter with a drive mechanism, as well as a tray mounted movably on the side surface of the shaft of the shaft and having a sector stop cooperating with a lever connected to the return mechanism.

A disadvantage of this device is the need for a controlled shutter and a pivotally mounted tray to prevent spillage of bulk cargo when loading the skip from the loading hopper.

The presence of these elements, including a spring, which tends to press the lever against the stop, complicates the design of the loading unit as a whole, and also reduces the reliability of its operation, which is an obstacle to the use of these devices in the construction of underground structures by the method of lowering wells.

The closest in technical essence and the achieved result is a self-unloading container adopted by the authors as a prototype.

The device comprises a housing, on the trunnions of which the load-bearing suspensions are pivotally mounted, and they themselves are installed between the levels of finding the centers of gravity of the empty and filled containers, and a latch mounted on one of the suspensions to hold the housing in a vertical position.

A cable is connected to the latch, the free end of which is brought out to a place accessible for servicing. When unloading the container, the worker pulls on the cable and frees the container from engaging with the suspension suspension.

Such container unloading technology is inconvenient for solving the task, namely, loading the skip to evacuate the soil from the production zone during the construction of underground structures. In addition, the presence of a person at the loading site is undesirable from the point of view of labor safety.

The purpose of the invention is to increase ease of use by self-tipping the loading container under the influence of a skip passing to the loading point.

In this case, the latch is released by pressing the bottom of the skip on its lever. In this case, there is no need for the presence of a person in the place where the skip is loaded.

To achieve this goal, there is provided a device for loading a container, preferably a skip, which comprises a support element, a loading container mounted on the support element to rotate about a horizontal axis located below the center of gravity of the loaded container, and a latch for securing the container when loading it.

The proposed technical solution differs from the prototype in that the latch of the loading container is adapted to interact with the skip, and the rear wall of the container is provided with a guide in the form of two brackets to return it to its original position when lifting the loaded skip.

Fig. 1 shows a device for loading a skip, general view: in Fig. 2 - view A in Fig. 1.

The device contains a support element

1 in the form of a welded frame, mounted on the wall of the lowering well.

On the support element 1 with the possibility of rotation around a horizontal axis of rotation 2, a loading container is installed

3. The axis of rotation 2 is located below the center of gravity of the loaded container 3 and is shifted relative to it towards the front wall of the container 3. In addition, a latch 4 s is installed on the supporting element 1

a counterweight 5 and a lever b for securing the container 3 when loading it. The rear wall of the container 3 is provided with a guide 7 in the form of two brackets, the ends of which extend beyond the upper edge of the rear wall

container 3 to return to its original position when lifting the loaded skip 8.

For raising the loaded skip 8 from the bottom of the lowering well, there are guides 9.
