Problems solved by technology

[0004] At present, the main methods used in coal mine roadways are cantilever roadheaders, continuous miners, and bolter machines. There are major problems in the excavation process, which cannot be formed at one time, and the roadway is not completed to a high degree. Correction; while the traditional circular roadheader has a low section space utilization rate, the number of supporting mechanisms is largely limited by the section shape, and additional equipment is arranged in the roadway, which requires secondary adjustments to the original prototype roadway ; Currently existing rectangular roadheaders have mostly elliptical shapes, so that the use efficiency at the corners is still low

Embodiment 1

[0036] Such as figure 1 , 2 , 9-11, this example provides a full-section rectangular rapid roadheader with a planetary wheel driving a Lello triangular cutter head, including a driving device, a shield structure, and a cutter head, and a driving device is placed in a hollow inside the shield structure , the cutterhead is located in front of the shield body structure, the cutterhead is a conical structure with a Lelot triangle as the cross-section, and the driving device is used to drive the Lelot triangle cutterhead at the front of the shield structure to move, and the A cutting head 1 is arranged on the cutter head.

[0037] The drive device includes a power part and a transmission part, the power part is an electric motor, and the transmission part is a planetary gear box, and the planetary gear box includes a box body, a front end cover of the box body, an eccentric input shaft 73, a planetary gear shaft , internal gear, eccentric inner turntable, between the eccentric in...

example 2

[0043] Such as Figure 3-5 As shown, the difference between this example and Embodiment 1 is that the cutter head of this example includes two cutter head structures, the two cutter head structures are arranged in a staggered front and rear, and each cutter head structure is connected to a driving device.

Embodiment 3

[0045] Such as Figure 6-8 As shown, the difference between this example and Embodiment 1 is that the cutter head of this example includes two two cutter head structures arranged side by side, and the two cutter head structures do not interfere with each other, and the steering of the two cutter head structures is opposite , each cutterhead structure is connected with a driving device; compared with the cutterhead of embodiment 1, the cutterhead of this example reduces the structure of the triangular edge part of the original cutterhead, and only the main frame is retained to make the double cutterhead turn On the contrary, it is arranged in parallel to avoid interference and carry out mining.

Abstract

The invention discloses a full-section rectangular rapid heading machine with a planet wheel driving Lello triangular cutterhead. Thefull-section rectangular rapid heading machine comprises a driving device, a shield body structure and the cutterhead, the driving device is arranged in the shield body structure in a hollow manner, the cutterhead is positioned in front of the shield body, the cutterhead is of a conical structure with a Lello triangle as a cross section, The driving device is used for driving the Lello triangular cutterhead in front of the shield body to move, a cutting head is arranged on the cutterhead, the cutting efficiency and the use efficiency of the corners of the section can be effectively improved, meanwhile, the size of the cut section and the overall size of the tunneling machine can be changed by reasonably adjusting the transmission ratio of the gear box and the structural size of the cutterhead, and different mining requirements can be met.

Description

technical field [0001] The invention relates to the technical field of coal roadway excavation, in particular to a full-section rectangular rapid excavation machine with a planetary wheel driving a Lello triangular cutter head. Background technique [0002] Since the 21st century, with the rapid development of the national economy, my country's urbanization process has been accelerating. With the rapid growth of domestic urban rail transit, railways, highways, water conservancy, municipal engineering and other construction projects, the scope of use of roadheaders and The mining form constantly puts forward new demands, which further promotes the continuous development and progress of roadheaders in our country. [0003] Although the supply and demand of coal mining roadheaders have basically reached a balance since the 21st century, due to the high price of oil and natural gas, domestic coal mines' demand for roadheaders will remain at the current level, coupled with the rep...
