The surface of the disc cutter 16 on the side close to the cutter disc axis is referred to as the inner side, and the other side surface of the disc cutter 16 is referred to as the outer side. Besides the positive installation, the hob is contacted with the rock in four installation modes of inward inclination, outward inclination, forward inclination and backward inclination.
When the installation mode is different, the load of the disc cutter 16 in the rock breaking process and the rock breaking energy consumption of the disc cutter are different. Theoretical research shows that the forward inclination and outward inclination installation modes of the disc cutter 16 have great influence on energy consumption and rock breaking load.
Because the side unbalance force can lead to the cutting edge to take place the eccentric wear, shorten hobbing cutter life-span, and the side hobbing cutter has the installation inclination in the installation, and proper hobbing cutter mounting means can realize that specific energy consumption is lower relatively, rock breaking efficiency is higher relatively, and the cutting edge is difficult for taking place the eccentric wear.
The invention relates to a disk cutter rotary cutting rock breaking tester with an adjustable installation angle, which provides three installation modes:
1. and (3) vertical installation: keeping two adjusting screw rods I11 still, adjusting screw rod II12 still, the wedge block for positioning is a cuboid, and the compensation wedge block 14 is matched with the screw rod 15 to lock the disc cutter 16.
The disc cutter 16 is used as a main cutter for breaking rock by the TBM, and is normally vertically arranged, such as a cutter ring 31 and rock 32 shown in figures 11 and 12. The disc cutter has two characteristics when being installed: the cutting edge face of the disc cutter 16 is vertical to the rock-breaking face, and the axis of the disc cutter 16 is vertical to the rotation axis of the cutter head.
2. And (3) outward-inclined installation: the single side precession of accommodate the lead screw I11, the opposite side is motionless, accommodate the lead screw II12 is motionless, the wedge that the location was used is right angle trapezoidal body, and wedge hexahedron sets for 1 ~ 10 degrees ten groups, and compensation voussoir 14 cooperates with screw 15 and locks disk cutter 16.
The disc cutter is mounted in a forward-inclined manner by rotating the disc cutter in the rotational direction by a predetermined angle with a rotation axis of a straight line parallel to the axis of rotation of the cutter head, in which the maximum depth point of the disc cutter 16 is located, as shown in fig. 13.
3. Mounting in a forward inclining way; the adjusting screw rod 1 is fixed, the adjusting screw rod 2 is screwed downwards on one side, the wedge blocks for positioning are right-angled trapezoidal bodies, namely wedge-shaped hexahedrons, ten groups of 1-10 degrees are set, and the compensation wedge blocks 14 are matched with the screw rod 15 to lock the disc cutter.
Taking the central point of the disc cutter 16 as a rotation point, and rotating the disc cutter by a certain angle along the radial direction of the edge track circle, so that the disc cutter 16 is installed on the cutter head in such a posture, which is called as the installation mode of outward inclining the disc cutter, and outward inclining the disc cutter, as shown in fig. 14, the right side is a schematic diagram of the disc cutter installed with the central point of the disc cutter outward inclining the disc cutter acting on the rock; the left side is a schematic diagram of the disc cutter which is installed by the contact point of the cutter in an outward inclining mode and acts on the rock; the two are equivalent, where γ is the camber angle.
In the test machine the hob needs to be mounted on the tool holder, and in addition to the normal vertical mounting, also two mounting modes of forward tilting and outward tilting of the hob, a disc hob 16, are required, as shown in fig. 7.
The central section of the cutter shaft 13 is cylindrical, and the rotation around the axis is realized by the friction force of the tapered roller bearing. The cross section of the shaft extension section of the cutter shaft 13 is in the shape of an equilateral triangle, and edge rounding is performed, so that a cutter rest meeting two special installation modes is designed for the cutter shaft 13.
The forward tilting means that the two ends of the cutter shaft 13 have different left and right displacement differences relative to the original axis, the inclination angles are different, and the displacement difference values of the two ends of the corresponding cutter shaft are different, as shown in fig. 8. Camber refers to the difference in vertical displacement between the two ends of the cutter shaft, and the hob can be installed in a camber manner, as shown in fig. 9.
In order to facilitate the correct mounting of the disc cutter 16 on the holder 29 in accordance with the calculated values, the holder 29 is designed to be wedge-shaped, as shown in fig. 10, the holder 29 has an outer dimension of 280 × 180, 180 × 120mm3Is dug out 240 × 100 × 120mm3The structure of the tool apron 29 and the installation structure of the adjusting screw rod I11 and the adjusting screw rod II12 are shown in figure 10.
If the adjusting screw I11 and the adjusting screw II12 are not adjusted, the installation is normal; two kinds of inclined installation are realized by adjusting the adjusting screw rod I11 and the adjusting screw rod II12, in order to facilitate the disassembly and assembly of the screw rod and the wedge block, the ball screw rod is in threaded connection with the wedge block, and the compensation wedge block 14 is matched with the locking nut 30 to complete the clamping and positioning of the cutter shaft 13.
Considering that the disc cutter 16 is subjected to an upward vertical load during rock breaking, the wedge-shaped mounting opening of the tool apron 29 is directed vertically downward, the load of the compensating wedge 14 and the lock nut 30 is reduced, the tool holder 10 needs to be connected with a vertical loading system, and therefore a connecting piece needs to be designed, and the connecting part and the tool apron 29 are designed into bolt connecting structures which form locating surfaces with each other.
The inclined plane of the invention converts the line contact positioning at two sides into surface contact positioning, and the adjusting screw rod is in threaded connection with the threaded hole.
According to the disc cutter rotary cutting rock-breaking testing machine with the adjustable installation angle, the influence of different installation modes on the eccentric wear, the rock-breaking efficiency and the specific energy consumption of a hob is researched according to the fact that the disc cutter installation mode also has a large influence on rock breaking of the hob, a hob rotary cutting rock-breaking testing machine meeting the three installation modes is innovatively designed, the existing hydraulic drive is replaced by a motor-driven worm gear screw mechanism, an adjusting mechanism meeting the installation of the three hobs is designed, and in addition, a rock box is assembled by four assembling pieces so as to achieve rapid assembly and disassembly of a rock sample.
Fundamentally saves energy, improves the rock breaking efficiency, reduces eccentric wear of the cutter ring, prolongs the service life of the cutter, shortens the construction period, further reduces the engineering cost, and achieves the aim of reducing the burden of the country and the society. The experiment machine can make up the defect that the experiment machine is lacked in the research of breaking rocks by using the disc cutter, various working conditions are met by adjusting the installation angle of the cutter, and the defects that the existing rotary cutting rock breaking experiment table is large in size, single in working condition and inconvenient to assemble and disassemble are made up.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
