Description

The invention relates to construction and can be used for the development of strong soils, including frozen soils, as well as for the destruction of asphalt concrete pavements.

The purpose of the invention is to reduce the dynamic loads on the base machine and increase the efficiency of the installation in operation by reducing the energy consumption of soil development and increasing productivity.

In FIG. 1 illustrates a hoist for excavation, general view; figure 2 is a section aa in figure 1; Fig. 3 illustrates a process for introducing pointy supports; figure 4 - the process of cleavage of the soil; figure 5 - the process of separation of soil from the border of the face.

Installation of a lifting-impact action for excavation includes a hydraulic base machine 1 with an arrow 2 having a control hydraulic cylinder 3, and by means of a hinge assembly 4 is connected to a guide post 5, which has the possibility of vertical movement with respect to the hinge assembly 4 and is provided with pointed parts in the lower part supports 6. On the guide post 5 there is a lifting mechanism 7 connected to the working body 8 and consisting of hydraulic cylinders 9, a cable-block system 10, a lifting drive for the working body 11 and the carriage with Okami 12 connected with rods of hydraulic cylinders 9, embodied on their hulls guide post 5, and its cables are passed through the blocks 12 of the carriage.

Installation of lifting and impact action for excavation works as follows.

By means of the boom 2 of its control hydraulic cylinder 3 of the hydraulic base machine 1 and the hinge unit 4, the guide post 5 is mounted with the pointed supports 6 in a vertical position on the edge of the face. Then, the hydraulic cylinders 9 of the lifting mechanism 7 are turned on and the working element 8 is lifted through the cable-block system 10 and the lifting drive 11. The force from the masses of the working body 8, the guide rack 5 and the lifting mechanism 7 is due to the vertical movement of the guide rack 5 relative to the hinge node 4 is transmitted to the pointed supports 6, which are embedded with into the surface of the soil.

After that, by means of the hydraulic system of the base machine 1, the working fluid from the hydraulic cylinders 9 is removed and the working member 8 is discharged. Thus, the soil is cleaved.

Subsequently, several such successive cycles are performed. In this case, with increasing cycles, the introduction of the pointed supports 6 into the soil by increasing the jamming of the working body 8 is carried out with great effort and contributes to the development of spalling cracks / thereby reducing the duration of the introduction of the working body into the soil.

Then, with the raised working body 8, the control hydraulic cylinder 3 is turned on and the guide post 5 and the correspondingly pointed supports 6 are tilted through the hinge unit 4 .. then a piece of soil is torn off from the general array towards the open face. This can be done depending on the layer being developed and soil density both after several cycles and at the end of the development process.
