Problems solved by technology

[0003] In order to solve the problem that the existing roadheader cannot effectively process the side wall of the tunnel during the tunneling process, the present invention proposes a mechanical arm for the roadheader and a roadheader. The mechanical arm can be combined and installed on any type of roadheader. The mechanical arm of the present invention can be turned sideways, that is, it can be rotated left and right along the axis of the mechanical arm, so that the side wall surface of the tunnel can be effectively treated. The overall mechanical arm is small and flexible, with various functions, and is suitable for various working conditions homework

Embodiment 1

[0026] An embodiment of the present invention is, as figure 1 As shown, the base of the mechanical arm 1 is hinged with the flip connection seat 3 through the first hinge point 16, and the other end of the flip connection seat 3 is provided with a driving device 6, and the flip connection seat 3 can be positioned relative to the The base 1 of the mechanical arm is turned sideways.

[0027] A first rotating base 2 is connected between the base 1 of the mechanical arm and the flipping connecting seat 3, and the first rotating base 2 is connected with the base 1 of the mechanical arm through a first rotating shaft 17. The first rotating base 2 The other end of the first hinge point 16 is hinged with the flip connection seat 3, and the first hinge point 16 is arranged on the long axis of the mechanical arm, so that the excavation device 6 can be turned left and right; the mechanical arm base 1 and the second The first telescopic oil cylinder 7 is connected between the first rotat...

Embodiment 2

[0031] Such as Figure 2-3 As shown, it is another embodiment of the present invention. On the basis of Embodiment 1, this embodiment adds the forward and backward movement function of the driving device 6, that is, the driving device 6 can be moved relative to the mechanical arm base 1 Moving back and forth, in this embodiment, the tunneling device 6 can move back and forth 0.5m in the direction of tunneling, so as to improve the strength and efficiency of tunneling.

[0032]Specifically, a mobile base 4 is provided between the turning connection base 3 and the tunneling device 6, and one end of the moving base 4 is connected to the turning connection base 3 through a second rotating shaft 19, and the second rotating shaft 19 can make The moving base 4 can rotate up and down with the second rotating shaft 19 as the center of a circle, and the driving device 6 is arranged on the moving base 4 , and the driving device 6 can slide back and forth relative to the moving base 4 . ...

Embodiment 3

[0038] In this embodiment, a roadheader is provided. The roadheader in this embodiment includes any mechanical arm for a roadheader in Embodiment 1 or Embodiment 2 above, and the mechanical arm for a roadheader is combined on the roadheader or It is used on the trolley, specifically, the mechanical arm of the roadheader is arranged on the body of the roadheader. The body of the roadheader is the body of the existing roadheader, or it can be a construction trolley. When the main body rotates, when the mechanical arm of the roadheader is set on the existing roadheader or construction trolley, the entire mechanical arm of the roadheader can be driven to rotate left and right or up and down through a rotating mechanism or a telescopic mechanism (such as a telescopic oil cylinder) , thereby increasing the construction range of the mechanical arm of the roadheader and improving the flexibility of the construction of the mechanical arm of the roadheader.

Abstract

The mechanical arm comprises a mechanical arm base, the mechanical arm base is connected with a tunneling device, the tunneling device can rotate relative to the mechanical arm base, and the tunneling device can laterally turn over relative to the mechanical arm base. According to the mechanical arm, lateral overturning is conducted, so that the mechanical arm can rotate left and right along the axis of the mechanical arm, the side wall face of a tunnel can be effectively treated, and the mechanical arm is small, exquisite, flexible, diverse in function and suitable for operation under various working conditions.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to a mechanical arm for a roadheader and a roadheader. Background technique [0002] The roadheader acts on the tunnel wall to initially break the tunnel wall, complete the initial excavation of the tunnel, and then reinforce the tunnel wall through subsequent engineering. However, the existing roadheader and the mechanical arm used on the roadheader are relatively small large, the overall volume is huge, and the mechanical arm is not flexible enough in the process of use, especially for the side wall of the tunnel, it cannot be effectively processed, and most of the existing roadheaders are for processing large-scale tunnels. To correct the side wall surface, it is necessary to manually use a breaker for subsequent processing. The entire construction process is complicated and time-consuming, and the construction efficiency cannot be effectively improved. Contents...
