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 propulsion mechanism of a roadheader, which is installed at the tail of the roadheader and includes a telescopic part and a propulsion part. The propulsion part is connected to the output end of the telescopic part. A thrust is applied to the walking surface of the roadheader, so that the roadheader has a tendency to move forward. During the uphill process of the roadheader, the telescopic part is used to drive the propulsion part to apply a thrust to the roadheader's walking slope. The reaction force of the thrust makes the roadheader have a tendency to move forward, and the forward power of the roadheader itself is superimposed on the thrust. After the reaction force, the whole machine of the roadheader has enough uphill power, and it is not easy to slip and other phenomena, which ensures the safety of the on-site staff. The invention can be applied to the auxiliary propulsion of the boring machine.

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...
