Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of the embodiments of the present utility model will be given with reference to the accompanying drawings, but the described embodiments of the present utility model are some, but not all embodiments of the present utility model.

As shown in fig. 1 and 3, a tunneling machine for a tunnel includes: the traveling device 1 is hinged with a big arm 2, the tail end of the big arm 2 is hinged with a small arm 3, and the big arm 2 and the small arm 3 are driven by hydraulic cylinders.

Specifically, as shown in fig. 1 and 3, the tail end of the small arm 3 is hinged with a mounting seat 4, the hinge axis of the mounting seat 4 is parallel to the hinge mutual axes of the small arm 3 and the large arm 2, the tail end of the mounting seat 4 is rotatably provided with a bucket 5, the rotating axis is perpendicular to the end face of the tail end of the mounting seat 4, the width of the front end of the bucket 5 is smaller than that of the rear end, a conical structure is formed, and the cone top of the bucket is forward so as to split and crush a rock wall.

As shown in fig. 1, during the tunneling process, the bucket 5 is rotated to have its bottom surface upward to form a downward hook structure, so as to facilitate the excavation and soil planing work. As shown in fig. 3, when the bottom surface of the bucket 5 is downward, the bucket can be used as loading equipment, the debris is loaded into a transport vehicle by the bucket, and the tunneling and loading functions are realized by the same tunneling machine, so that the construction in the tunnel is more convenient. In addition, in the process of loading the mud-stones, the mud-stones can be poured out from the side face of the bucket 5 by rotating the bucket, so that the bucket 5 is prevented from being lifted to a higher position, and the heading machine is more suitable for the working environment in a tunnel.

Preferably, as shown in fig. 2, a gear 6 is sleeved on a rotating shaft of the bucket 5, the rotating shaft penetrates through the mounting seat 4, a rack 7 meshed with the gear 6 is arranged on the rear end face of the mounting seat 4, a telescopic device 8 is arranged on the top face of the mounting seat 4 and used for driving the rack 7 to reciprocate along the linear direction, and accordingly the bucket 5 is driven to rotate through the gear 6, and the telescopic device 8 is a hydraulic cylinder.

It is further preferred that the overall height of the telescopic device 8 after assembly with the mounting base 4 is smaller than the height dimension of the bucket 5, so as to hide the telescopic device 8 behind the bucket 5 and avoid impact on the telescopic device during construction.

Preferably, the bucket 5 is driven by a worm and worm wheel mechanism, the worm wheel is arranged on a connecting shaft of the bucket 5, the connecting shaft penetrates through the mounting seat 4, the worm is arranged on a main shaft of a motor, the motor is arranged on the mounting seat 4, the bucket 5 can be effectively prevented from automatically rotating by utilizing a self-locking function of worm and worm wheel transmission, so that the stability of the bucket 5 relative to the position of the mounting seat 4 is kept, and tunneling construction and reversed loading and dumping are facilitated.

Preferably, as shown in fig. 1, the bottom of the bucket 5 is provided with a plurality of ribs 51, and the ribs 51 are arranged in the front-rear direction of the bucket 5 to increase the structural strength of the bottom surface of the bucket 5, thereby enhancing the tunneling capability of the bucket.
