specific Embodiment 1

[0085] Concrete embodiment 1 of the roadheader provided by the present invention, in the present embodiment, take the roadheader as the normal pressure cutter head muddy water roadheader, the material is the knife barrel assembly 37 that cutter and knife barrel are formed, and the material transfer operation is that the material is transferred to The transfer at the cutter head is taken as an example to introduce the structure of the roadheader and the material transfer method in the present invention, as follows:

[0086] The partial structure of the boring machine provided by this embodiment is as follows: figure 1 As shown, a shield body 1 is included, and a main drive 2 is arranged in the shield body 1. The main drive 2 has a drive box, and the main drive 2 is installed with a cutter head 3 through a cutter head installation structure. In order to drive the cutter head to rotate, the main drive 2 also has a driving device, such as image 3 As shown, the driving device inc...

specific Embodiment 2

[0108] The specific embodiment 2 of the roadheader provided by the present invention mainly differs from embodiment 1 in that in embodiment 1, the crossbeam on the rear side of the cutter head is a figure-eight beam. In this embodiment, the crossbeam is any The cutter head is connected before the rotating part of the central rotary joint so that the cutter head can drive the structure of the rotating part of the central rotary joint. For example, the crossbeam can be a straight beam, and the two ends of the straight crossbeam pass along the front and rear directions. The connecting arm is connected with the cutter head, and the middle part is connected with the rotating part of the central rotary joint through the connecting arm extending along the front and rear direction.

specific Embodiment 3

[0109]The specific embodiment 3 of the roadheader provided by the present invention mainly differs from embodiment 1 in that in embodiment 1, the movement path of the material transfer trolley passes through the bottom of the main drive center cabin. In this embodiment, the material channel It is set on the side of the installation hole of the slewing center, so that the movement path of the material transfer trolley passes by the side of the central passage. For this structure, when transferring materials, the beam can be turned to a vertical state, so that the material can pass by the side of the beam. Of course, in other embodiments, the material channel can also be opened above the installation hole of the central rotary joint, so that the moving path of the material transfer trolley passes through the upper part of the central channel and carries the material through the top of the beam.

[0110] The specific embodiment 4 of the roadheader provided by the present invention...

Abstract

The invention belongs to the field of tunneling equipment, and particularly relates to a tunneling machine and a tunneling machine material transfer method.The tunneling machine comprises a shield body, a main drive is arranged in the shield body, a cutterhead is arranged on the main drive, a cross beam connected with a rotating part of a center rotating connector is arranged on the rear portion of the cutterhead, and the tunneling machine further comprises a material transfer system; the material transferring system comprises a carrying mechanism which is arranged in the shield body and used for transferring materials between the tail of the shield body and the cutter head, the carrying mechanism comprises a bearing body used for bearing the materials and an attachment body used for allowing the bearing body to be attached, and the height distance between the bearing body and the attachment body is not changed in the material conveying process of the bearing body. The movement path of the bearing body passes through the main driving center channel and directly crosses the cross beam to extend towards the position of the cutter head, so that the carrying mechanism does not need to be arranged in a form of continuous matching of a transferring structure and a hoisting structure, the requirement of the carrying mechanism on the space of a chamber on the rear side of the cutter head is reduced, and the heading machine can be miniaturized.

Description

technical field [0001] The invention belongs to the field of tunnel boring equipment, and in particular relates to a boring machine and a material transfer method for the boring machine. Background technique [0002] During the use of the roadheader, it is necessary to replace the relevant parts at the cutter head. This process will involve the transportation of new parts to the cutter head and the transportation of the removed parts from the cutter head to the outside of the shield. out. [0003] The components used in the cutter head of the roadheader generally have a relatively large weight. For example, the weight of the cutter barrel with the cutter can reach several hundred kilograms or even more than one ton. A material transfer system is set up in the roadheader to transfer materials. For example, a Chinese invention patent with the application publication number CN110159287A and the application publication date of August 23, 2019 discloses a new type of tool trans...
