Description

Technical Field

[0001] The utility model relates to a tunneling machine, in particular to a high-efficiency double-arm horizontal axis tunneling machine. Background Art

[0002] Compared with the horizontal axis reducer, the advantage of the vertical axis reducer is that it has a simple structure and is easy to maintain. For high-hardness ores, the cutting efficiency of the vertical axis reducer is higher than that of the horizontal axis reducer.

[0003] The horizontal axis reducer has a larger contact surface than the vertical axis reducer. For ores with a hardness below F5, using a horizontal axis reducer is more efficient in cutting ores.

[0004] Time is money, efficiency is life. The higher the efficiency of the equipment, the greater the return, and the more popular it is with customers. However, due to the immature technology of domestic horizontal axis reducers, single-arm vertical axis was the main method, and double-arm was occasionally used. Basically, vertical axis reducers were used. Utility Model Content

[0006] A high-efficiency double-arm horizontal axis tunnel boring machine comprises a driving vehicle body and a tunnel boring machine body. The tunnel boring machine body is arranged at the front section of the driving vehicle body. Two tunnel boring machine bodies are arranged at the front end of the driving vehicle body. The tunnel boring machine body comprises a front mechanical arm and a rear mechanical arm. The front mechanical arm is fixedly connected to the rear mechanical arm. A cutting mechanism is installed at one end of the front mechanical arm away from the rear mechanical arm.

[0007] Furthermore, the cutting mechanism includes a driving base and a cutting head, wherein the cutting head is respectively installed on two horizontal sides of the driving base, and a driving motor is arranged in the driving base, and the cutting head is driven by the driving motor.

[0008] Furthermore, the cutting head is conical, and the diameter of one end of the cutting head close to the driving base is smaller than the diameter of the other end of the cutting head.

[0009] Furthermore, one end of the rear end mechanical arm away from the front end mechanical arm is installed on the top of the support base through a bearing, the support base is installed on the mounting base, the mounting base is installed on the rotating base, and the mounting base is rotatably connected to the mounting base.

[0010] Furthermore, it also includes a telescopic rod, one section of which is hinged to the front end of the bottom of the support base through a first hinge, and the other end of the telescopic rod is hinged to the bottom of the rear end mechanical arm close to one end of the front end mechanical arm through a second hinge.

[0011] Furthermore, it also includes reinforcing ribs, one end of which is fixedly connected to the top of the front-end mechanical arm, and the other end of the reinforcing rib is fixedly connected to the top of the rear-end mechanical arm.

[0012] The beneficial effects of the utility model are as follows:

[0013] The introduction of this efficient double-arm horizontal axis tunnel boring machine has brought about many beneficial effects. First, the double-arm design allows the tunnel boring machine to perform double cutting at the same time, greatly improving the tunneling efficiency. Compared with the traditional single-arm tunnel boring machine, the double-arm horizontal axis tunnel boring machine can complete more work in the same amount of time, significantly shortening the construction period and reducing costs. Secondly, the use of a horizontal axis reducer and cutting mechanism makes the structure of the equipment more stable, durable, and easy to maintain and operate, reducing maintenance costs and operating difficulties, and improving the reliability and durability of the equipment.
