Problems solved by technology

[0004] Using picks of different specifications can avoid the damage and rapid wear of small picks to a certain extent, but large picks still suffer from the same hard rock resistance, and the wear of large picks will also increase to a certain extent, and the service life will decrease
This method does not fundamentally solve the problem

Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, the present embodiment provides a cutting section of a roadheader, which mainly includes a support frame 4, a cutting head cutting group 7 and a diamond saw blade cutting group 8, and the four corners of the support frame 4 are provided with fixing devices. One side of the support frame 4 is provided with a horizontal movement mechanism, and the cutting head cutting group 7 and the diamond saw blade cutting group 8 are arranged on the horizontal movement mechanism.

[0035] In this embodiment, in order to improve the stability of the entire cutting part during operation, four fixing devices 5 are installed at the four corners of the support frame 4 . Specifically, each fixing device 5 includes an angle adjustment oil cylinder 13, a telescopic oil cylinder 14, a guide slider 15, a first hydraulic motor 16, a guide rail 17 and an auger rod 18, and the cylinder barrel of the angle adjustment oil cylinder 13 and the side of the suppor...

Embodiment 2

[0042] Such as figure 1 As shown, this embodiment provides a roadheader, including a rotary platform 22, a rotary cylinder 1, a height adjustment cylinder 2, a first mechanical arm 19, a posture adjustment cylinder 3, a second mechanical arm 20, and a third mechanical arm 21. It also includes the cutting part of the roadheader mentioned above; the tail end of the first mechanical arm 19 is hinged on the rotary platform 22, one end of the rotary cylinder 1 is fixed, the other end is hinged to the rotary platform 22, and the two ends of the height-adjusting cylinder 2 are connected to the rotary platform 22 respectively. 1. The first mechanical arm 19 is hinged, the second mechanical arm 20 is sleeved on the front end of the first mechanical arm 19 and the front end of the second mechanical arm 20 is fixedly connected to the third mechanical arm 21 through a flange, and the third mechanical arm 21 The front end is connected with the support frame 4, and the posture adjustment oi...

Embodiment 3

[0044] A kind of working method of boring machine as described in embodiment 2, comprises the following steps:

[0045] (1) After the roadheader advances to a predetermined position, adjust the left and right positions of the cutting section through the telescopic adjustment of the rotating cylinder 1, adjust the up and down position of the cutting section through the telescopic adjustment of the heightening cylinder 2, and adjust the vertical position of the cutting section through the telescopic adjustment of the second mechanical arm 20. The front and rear positions of the cutting part are adjusted parallel to the working surface through the telescopic adjustment of the posture adjustment cylinder 3;

[0046] (2) Then the first hydraulic motor 16 starts to drive the auger rod 18 to rotate, and the telescopic oil cylinder 14 pushes the guide slider 15 to advance along the guide rail 17, so that the auger rod 18 rotates and drills into the rock wall, thereby fixing the entire ...

Abstract

The invention relates to a heading machine cutting part and application thereof. The heading machine cutting part includes a supporting frame, cutting head cutting groups and diamond saw blade cuttinggroups, the four corners of the supporting frame are provided with fixing devices, one side of the supporting frame is provided with a horizontal moving mechanism, and the cutting head cutting groupsand the diamond saw blade cutting groups are arranged on the horizontal moving mechanism. According to the heading machine cutting part and application thereof, combination of the two groups of the diamond saw blade cutting groups and the two groups of the cutting head cutting groups is used for combined rock breaking, can be carried out synchronously, and the efficiency of rock breaking is effectively improved; and the fixing devices are introduced, a spiral drill pipe is used for drilling into the rock wall, the entire cutting part is fixed, stability in the working process of the cutting part is improved, and the fact that vibration of the cutting part caused by acting force of cutting and rock breaking by cutting heads, and consequently diamond saw blades are damaged can be effectively avoided.

Description

technical field [0001] The invention relates to a boring machine, in particular to a cutting part of the boring machine. Background technique [0002] Now the cutting of hard rock is mainly broken by the cutting head, but the efficiency of the cutting head is low in hard rock crushing, and the wear of the pick is serious. Although there are studies on the tooth arrangement of the cutting head of the roadheader, the arrangement and distribution of the cutting teeth can be improved. After the improvement, the load fluctuation of the cutting head can be significantly reduced, the load torque fluctuation can be reduced, and the cutting head can be improved to a certain extent. Work efficiency, but only relying on changing the distribution and arrangement of picks cannot fundamentally improve the efficiency of coal and rock crushing. [0003] Chinese patent document CN207960608U discloses a cutting device for a graded propulsion type high-efficiency coal shearer. The cutting dev...
