Problems solved by technology

[0005] Aiming at the technical problems that the existing pipe jacking machine direction adjustment system has a single control mode, it is not easy to get out of trouble when the shield body is stuck, and the shield tail posture cannot be self-adapted, the present invention proposes a multi-mode direction adjustment system and control method for a rectangular tunnel boring machine. It can realize three modes of single group control, conventional control and combined strengthening, so that the roadheader can better adapt to the serpentine advancement, especially the adaptive adjustment of the shield tail attitude can better adapt to the curve excavation, and it is easier to block the shield body out of trouble

Embodiment 1

[0028] Example 1, such as figure 1 As shown, a multi-mode steering system for a rectangular tunnel boring machine includes a fuel tank 1 and a cylinder group. Control the movement of the shield body of the pipe jacking machine. The oil tank 1 is connected to the oil cylinder group through a mode control module, and the mode control module is used to control the flow of hydraulic oil in the oil tank 1 to the oil cylinders in the oil cylinder group. There are at least four sets of the mode control module corresponding to the oil cylinder groups, and the oil cylinder groups are evenly distributed around the circumference of the shield body, corresponding to the up, down, left, and right sides of the shield body, and each group has at least one oil cylinder, and the four directions of up, down, left, and right must be able to realize Turn to function. The oil tank 1 is connected to the mode control module through the oil inlet pipeline, and the oil inlet pipeline inputs hydrauli...

Embodiment 2

[0034] Example 2, such as figure 2 As shown, a control method for the multi-mode steering system of a rectangular tunnel boring machine:

[0035] The cylinder group includes the first cylinder group A, the second cylinder group B, the third cylinder group C and the fourth cylinder group D, the first cylinder group A, the second cylinder group B, the third cylinder group C and the fourth cylinder group Group D is respectively connected with a mode control module, that is, one mode control module controls one oil cylinder group.

[0036] Single-group control mode: the cylinders in one cylinder group are in a locked state, the two cylinder groups are in a floating state, and the cylinders in the other cylinder group are extended or retracted. The four cylinder groups can be combined arbitrarily, up, down, left, All four directions on the right can be adjusted to realize the fine adjustment of the attitude of the roadheader.

[0037] Conventional control mode: Two of the cylind...

Abstract

The present invention proposes a multi-mode steering system and control method for a rectangular tunnel boring machine, which is used to solve the problem that the existing pipe jacking machine steering system has a single control mode, it is not easy to get out of trouble when the shield body is stuck, and the posture of the shield tail cannot be self-adapted. question. The invention comprises a fuel tank and an oil cylinder group, the fuel tank is connected with the oil cylinder group through a mode control module; at least two groups are arranged correspondingly between the mode control module and the oil cylinder group, the fuel tank is connected with the mode control module through an oil inlet pipeline, and the mode control modules are respectively connected with the The rod chamber pipeline is connected with the rodless chamber pipeline, the rod chamber pipeline is connected with the rod chamber of the oil cylinder in the cylinder group, and the rodless chamber pipeline is connected with the rodless chamber of the oil cylinder in the oil cylinder group; the mode control module Connect with oil return line. The present invention allows the roadheader to have multiple steering modes through the different control modes of the electromagnetic reversing valve and the electromagnetic ball valve, so that the roadheader can better adapt to the serpentine advancement, and the self-adaptation of the shield tail posture can better adapt to the curve excavation. It is easier to get out of trouble when the shield body is stuck.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a multi-mode steering system and control method for a rectangular tunnel boring machine. Background technique [0002] With the continuous progress of human civilization, the environmental pollution of urban ground transportation has attracted more and more attention. How to develop and utilize urban underground space more efficiently has become an issue of concern to the industry. In the construction of urban tunnels, the shield construction method has unique advantages. Affect urban ground transportation, normal life of urban residents, obtain good engineering quality and high construction speed, etc., and rapidly promote and develop. During the excavation process of the pipe jacking machine, there will be curve excavation and the phenomenon that the axis deviates from a certain angle. It is necessary to adjust the direction and correct the deviatio...
