Description
Technical Field
The invention relates to the technical field of double-mode heading machines, in particular to a double-speed switching transmission system of a double-mode heading machine.
Background
With the continuous development of economy and tunnel construction technology in China, the requirements on the quality and the construction speed of tunnel construction are higher and higher. The method is suitable for the high-quality rapid tunneling requirement of tunnel construction under different geological conditions on the same tunnel path. Tunneling equipment has been converted from a single heading machine model to a multi-function heading machine model or hybrid heading machine model. While the main representatives of the multifunction or hybrid heading machine types are dual-mode heading machines.
At present, generally, the realization process of the dual-mode heading machine mainly comprises the step of completing the transformation of a cutterhead, a sealing mode and a slag discharging mode in the shortest time to convert the heading mode. The structure of the heading machine is suitable for heading under soft soil, rock or mixed geological conditions. The switching of the drive mode is only a structural form. So that after switching from one mode to another, fast tunnelling cannot be achieved in the new mode. Because there is a conflict in the performance requirements of each of the two modes when transitioning from one mode to the other — that is, a conflict in which the cutterhead torque and speed requirements are inconsistent in the different modes: the soft soil mode (EPB mode) requires that the transmission system can provide low rotating speed and large torque for the cutter head; while the hard rock mode requires that the drive train be able to provide high rotational speed low torque (relative to low rotational speed high torque) to the cutterhead. The contradiction is not solved only by modifying the structure. When a soft soil mode is used as a basic machine model to be reformed into a dual-mode tunneling machine model, the dual-mode tunneling machine has no problem when working under the low-rotating-speed and high-torque characteristics of a soft rock mode, but a transmission system cannot provide higher output rotating speed for a cutter head under the hard rock mode, and the rotating speed is limited by the low-rotating-speed and high-torque characteristics designed in the soft soil mode; when the machine model of the dual-mode heading machine is changed from a hard rock mode to a basic machine model, the dual-mode heading machine has no problem when working under the characteristics of high rotating speed and low torque of the hard rock mode, but the transmission system can not provide low-speed and high torque for the cutter head under the soft soil mode, because the low-speed and high torque is limited by the high-speed and low torque designed in the hard rock mode.

Preferably, the annular groove of the shifting fork clutch is sleeved with the shifting head of the switching handle, and the lower end of the switching handle is rotatably connected to the transmission shell through a rotating pin shaft.

The annular groove of the shifting fork clutch 9 is sleeved with a shifting head of a switching handle 10, and the lower end of the switching handle 10 is rotatably connected to the transmission shell 1 through a rotating pin shaft. The rotation of the switching handle 10 drives the shifting fork clutch 9 to slide left and right to realize high and low speed switching.
The function implementation process of the invention comprises the following steps:
1. implementation process of low-speed large-torque output characteristic of dual-mode heading machine in soft soil mode
The input gear shaft 2 is connected with the output shaft of the driving motor, so that the rotating speed and the torque of the motor can be transmitted to the intermediate gear shaft 4 through the first gear 3 according to the designed transmission ratio and then transmitted to the low-speed output transmission gear 5 through the intermediate gear shaft 4; as shown in fig. 3, the switching handle 10 is rotated to the right to a position of about 104.5 degrees, and then the shifting fork clutch 9 is driven to combine the low-speed output transmission gear 5 and the two-speed switching transmission output spline shaft 8 together, and at this time, the high-speed output transmission gear 7 is in an idle state, so that the low-speed and high-torque output characteristic in the soft soil mode is realized.
2. Implementation process of high-speed low-torque output characteristic of dual-mode heading machine in hard rock mode
The rotating speed and the torque of the motor are transmitted to an intermediate gear shaft 4 through a first gear 3 according to the designed transmission ratio through an input gear shaft 2, and then transmitted to a high-speed output transmission gear 7 through a second gear 6 through the intermediate gear shaft 4; as shown in fig. 4, the switching handle 10 is rotated to the left to a position of 90 degrees, and then the shift fork clutch 9 is driven to combine the high-speed output transmission gear 7 and the two-speed switching transmission output spline shaft 8 together, and at this time, the low-speed output transmission gear 5 is in an idle state, so that the high-speed low-torque output characteristic in the hard rock mode is realized.
The invention solves the problem that the newly designed single transmission ratio of the dual-mode heading machine can not simultaneously meet the requirements of mutually contradictory cutterhead speed and torque characteristics under two working states, thereby abandoning the design of compromise of the dual-mode heading machine with partial performance under the two working states. When a soft soil mode is used as a basic machine type to be transformed into a dual-mode heading machine type, the problem that the single transmission ratio cannot meet the performance requirement of high rotation speed of a cutter head in a hard rock mode working state is solved; when a hard rock mode is used as a basic machine type to be transformed into a dual-mode tunneling machine type, the problem that the single transmission ratio cannot meet the performance requirement of large torque of a cutter head under the working state of a soft soil mode is solved.
As shown in fig. 6 to 9, the invention also discloses a dual-mode heading machine, which applies the dual-speed switching transmission system. Before the dual-mode heading machine works, the maximum transmission ratio (namely the maximum output torque and the minimum output speed) in a soft soil mode and the minimum transmission ratio (namely the maximum output speed and the minimum output torque) in a hard rock mode can be determined by calculation according to the detected water texture geological condition, the planned tunnel diameter, the burial depth and the like; when a soft soil mode is used as a basic model to be modified into an XRE dual-mode model, calculating and adjusting the maximum transmission ratio in the soft soil mode according to the detected water texture geological condition, the diameter of a tunnel planned to be excavated, the burial depth and the like, and calculating and determining the minimum transmission ratio in the hard rock mode; when the hard rock mode is used as a basic model to be modified into an XRE dual-mode model, the minimum transmission ratio under the hard rock mode is calculated and adjusted according to the detected water texture geological condition, the diameter of a tunnel planned to be excavated, the buried depth and the like, and the maximum transmission ratio under the soft rock mode is calculated and determined.
Fig. 6 shows the cutterhead 11 and the two-speed switching transmission system of the dual-mode heading machine in a hard rock state. In this state, the double-speed switching transmission system of the double-mode heading machine is switched to a high-speed gear, so that the requirement of high rotating speed of the cutter head 11 in the hard rock mode is met;
fig. 7 shows the cutterhead 11 and the two-speed switching transmission system of the dual-mode heading machine in a soft soil condition. In this state, the double-speed switching transmission system of the double-mode heading machine is switched to a low-speed large-torque gear, so that the large-torque requirement of the cutter head 11 in the soft soil mode is met.
As shown in fig. 8 and 9, the dual mode heading machine of the present invention is provided with 8 sets of drives, each set of drives including the dual speed switching drive train of the dual mode heading machine of the present invention.
