Description

(54) EXECUTIVE BODY OF THE PASSAGE BOARD

one

The invention relates to the construction of tunnels and can be used for complex mechanization of work in the area under the Shieldov Prokhotsk.

The shield is known with a bucket body installed on a support - a longitudinal beam suspended under the top shield jacks. The actuator is swept along the longitudinal axis of the shaft and, in addition, it has the ability to pivot in a vertical transverse plane at an angle relative to the support beam l3.

A fixed-length longitudinal beam does not allow KOBiua to rotate around the vertical axis, necessitating the use of equipment to transfer the rock mass, for example, an intermediate conveyor or container from which the rock mass is subsequently sent to the trolleys.

Known working body to the device for the excavation of underground workings, made in the form of reversible shovel mounted pivotally on the horizontal axis 2.

In the specified device, the back shovel is mounted on the housing with the possibility of reciprocating dislocation. Such an operating member is closest to the invention in its technical essence and the achieved result.

However, the range of action of the backhoe is limited by turning the bucket in the scooping plane to 8 ° around the horizontal axis and by longitudinal movement of the bucket with developed soil by the stroke of the working cylinder piston.

To increase the maneuverability of the executive body of the tunnel shield, it is equipped with a rotary column hinged to the housing, a hand and controlled hydraulic cylinders, while the rotatable KQ barrel has a central shaft with a rotary drive around the longitudinal axis,
