Problems solved by technology

[0003] However, when the roadheader excavates in the roadway, it often encounters a roadway with a slope, or when it encounters a large slope in the process of going uphill, the driving part of the roadheader often suffers from insufficient power and slipping, which directly affects the overall performance. The working conditions of the machine and the safety of personnel in the roadway and the surrounding working environment

Embodiment Construction

[0018] Such as figure 1 The roadheader shown walks forward along the direction of the arrow on a slope, and it includes a fuselage 1, a walking track 2 is provided at the bottom of the fuselage 1, an auxiliary propulsion mechanism 3 is installed at the bottom of the tail of the fuselage 1, and The auxiliary propulsion mechanism 3 is located behind the crawler belt 2 .

[0019] Generally speaking, roadheaders traveling on slopes will encounter the problem of insufficient uphill power, causing slippage and other phenomena, which seriously affect the safety of staff. The auxiliary propulsion mechanism 3 in the embodiment can provide additional auxiliary thrust for the advancement of the roadheader. After the auxiliary thrust is superimposed with the power of the roadheader itself, it can ensure that the roadheader can move forward stably without slipping backwards.

[0020] Such as figure 2 As shown, the auxiliary propulsion mechanism at least includes a telescopic part and a ...

Abstract

The invention discloses an auxiliary pushing mechanism for a tunneller. The auxiliary pushing mechanism is installed at the tail of the tunneller and comprises a telescopic component and a pushing component. The pushing component is connected to the output end of the telescopic component. When the telescopic component stretches out, the pushing component applies thrust to the walking surface of the tunneller, so that the tunneller has a forward movement trend. In the uphill process of the tunneller, the telescopic component drives the pushing component to apply thrust to the walking slope surface of the tunneller, and the counter force of the thrust enables the tunneller to have a forward movement trend; and meanwhile, after the counter force of the thrust is overlaid with the advance force of the tunneller, the complete tunneller has enough uphill power, the phenomena of slipping and the like are not prone to happening, and the safety of working personnel on the site is ensured. The auxiliary pushing mechanism can be applied to auxiliary pushing of tunnellers.

Description

technical field [0001] The invention relates to the field of boring machines, in particular to an auxiliary propulsion mechanism of the boring machine. Background technique [0002] The roadheader is a large-scale machine used to excavate roadways in coal mines. The whole machine is mainly divided into: cutting part, shovel part, first conveyor, main body part, walking part, rear support part, etc. In order to maintain the stability of the whole machine, there is a rear support device at the rear of the whole machine. The common rear support device only has a pair of support cylinders to support the whole machine. [0003] However, when the roadheader excavates in the roadway, it often encounters a roadway with a slope, or when it encounters a large slope in the process of going uphill, the driving part of the roadheader often suffers from insufficient power and slipping, which directly affects the overall performance. The working conditions of the machine and the safety of...
