Mechanical driving type double-disc heading device used for heading machine

Abstract

The invention discloses a mechanical driving type double-disc heading device used for a heading machine. The heading device comprises two disc-shaped heading heads. The heading heads are arranged at the upper and lower sides of a third shell correspondingly. A first shell and a second shell are arranged at one side of the third shell. The first shell is arranged on the side away from the third shell. A conveying mechanism is arranged inside the first shell and comprises a first driving gear and a second driving gear. Both the first driving gear and the second driving gear are fixed to a connecting shaft. One end of the connecting shaft is connected with output shafts of a first servo motor and a second servo motor through couplers correspondingly. The first servo motor is mounted on a first mounting plate. The side, away from the first servo motor, of the first mounting plate is connected with the inner wall of the first shell through a telescopic frame. The second servo motor is mounted at the tail end of a piston rod of a cylinder. A telescopic mechanism is arranged in the second shell.

Description

technical field [0001] The invention relates to a tunneling device, in particular to a mechanically driven double-disk tunneling device for a tunneling machine. Background technique [0002] A roadheader is a machine used to excavate roadways on flat ground. There are many types of roadheaders: according to the operation object, it can be divided into ordinary machine and tunnel boring machine; according to the operation method, it can be divided into open type roadheader and shield type roadheader. The working mode of the roadheader: it is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a reloading mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good lane quality, but the cost is high, the structure is complicated, and the loss is also large. [0003] At present, the expansi...

It has the advantages of safety, high efficiency and good lane quality, but the cost is high, the structure is complicated, and the loss is also large

[0003] At present, the expansion and contraction of the tunneling head of the roadheader needs to be driven by the oil cylinder, and the rotation of the tunneling head needs to be driven by the motor, resulting in more driving components and more energy consumption. At the same time, when the roadheader is working, the oil cylinder and the motor need to work in real time, which is easy Damage to the oil cylinder and motor will easily reduce the service life of the roadheader, which needs to be improved
