Description

The invention relates to roadheaders, and in particular to the executive body of the arrow-shaped type roadheader, designed to destroy the massif during the preparatory workings by the combine method.

The aim of the invention is to simplify the design and increase the reliability and safety of work.

Figure 1 shows a roadheader, side view; : in figure 2 is the same, a top view; in Fig.Z - section aa in Fig.2; figure 4 is a section bB in figure 1; figure 5 - ball joint; figure 6 is a view In figure 5.

A roadheader includes a housing 1 and an actuator 2, containing a telescopic boom 3, mounted on the housing 1, using a ball joint 4 having a movable part 5 and a fixed part 6. The boom consists of a frame 7, a breaker bit '8 with a drive 9. On the boom and the frame are pivotally fixed to the cylinder 10 for supplying the crown to the bottom, and between the body 1 and boom 3 there are mounted hydraulic cylinders 11 for lifting, pivotally connected to the boom and to the body. An arcuate support 12, rollers 13 with the possibility of rotation and a rotation cylinder 14 are fixed on the housing 1. On the rods of the lifting hydraulic jacks 11, sliders 15 are mounted movably mounted on the arc-shaped support 12. Between the ball joint 4 and the rotation cylinder 14, flexible rods 16 are installed, which are in contact with the rollers 13 and mounted on the movable part 5 of the ball joint 4 and the rotation cylinder 14. The drive is made in the form of a hydraulic motor.

In the proposed tunneling machine, the ball joint for turning the body in horizontal and vertical planes is made in two versions: the movable part 5 is made in the form of a ball (see Figs. 1-3) and the fixed part 6 is made in the form of a ball (see Fig. 5).

The executive body of a roadheader works as follows.

The working fluid under pressure from the oil station of the combine is fed into the hydraulic motor, hydraulic cylinders 10,11,14, through high pressure hoses through fittings. The breaker crown 8 on the boom using the hydraulic cylinder 10 is fed to the bottom when rotating it with a hydraulic motor

9. After introducing the breaker crown into the array to the required depth, the actuator is rotated in the vertical plane with the help of hydraulic cylinders 11 and in the horizontal plane with the help of hydraulic cylinder 14 connected to the movable part 5 by flexible rods 16 around the center of the ball joint. After processing the face, the broken rock mass is removed by the combine’s loading unit or by gravity along the chute and estrus built into the combine body, the combine is fed to the face, and the cycle repeats.

The control of the hydraulic motor 9, hydraulic cylinders 11 lift, 14 rotation, 10 feed crowns, connected hydraulically to the hydraulic system of the combine through the fittings and high pressure hoses, is carried out from the control panel of the tunneling machine.
