Description
Technical Field
The utility model relates to a entry driving machine technical field provides a cut rotation mechanism and entry driving machine that has this cut rotation mechanism very much.
Background
Fig. 1 is a schematic structural diagram of a cutting and slewing mechanism of a boom-type roadheader. The frame (1) and the outer ring of the slewing bearing (3) are fixed together by dozens of slewing bearing bolts (2) which are uniformly distributed on the circumference. The rotary table (5) and the inner ring of the rotary support (3) are fixed together by dozens of rotary table bolts (4) which are uniformly distributed on the circumference. The slewing bearing bolt (2) and the turntable bolt (4) are both hexagonal head perforated bolts, and the shape is the same as that specified in GB 32.1. In the state of the whole machine, the front part of the rotary table (5) is connected with the cutting part of the heading machine. The development machine is the main equipment of the coal mine tunnel development comprehensive excavation process system. The heading machine breaks down the rock stratum of the roadway by cutting, so that the roadway is formed. The type and the property of the surrounding rock of the roadway are not uniform, and the cutting part cuts the rock, which is an intermittent cutting process. Therefore, during the working process of the heading machine, overload is difficult to avoid, and the breakage fault of the rotary table bolt is easy to occur. If the rotary table bolt breaks down, the normal production operation of the heading machine is affected. In the prior structure, broken bolt stub sections on the inner ring of the slewing bearing (3) are taken out, and at least the rotary table (5) is dismounted; if the rotary table (5) is only disassembled, the residual sections cannot be taken out, and the whole rotary mechanism is completely disassembled. The repair operation has many working procedures, the labor intensity of operators is high, the quality control is difficult, and the equipment fault downtime is long.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a cutting rotation mechanism and have this cutting rotation mechanism's entry driving machine to reduce repair work volume and fault down time, improve equipment utilization.
The broken fault of the rotary table bolt is processed, if the parts of the rotary table bolt, the rotary table, the rotary support bolt, the rotary support and the like which are not broken are not disassembled, namely the broken bolt stub section still arranged on the inner ring of the rotary support is taken out in the assembly state of the cutting rotary mechanism, the work of hoisting, fastening, checking, carrying and the like is reduced, and the maintenance time can be shortened. And a fabrication hole is formed at the position, which is opposite to the rotary table bolt, on the frame. And all the rotary table bolts pass through the upper part of the fabrication hole by rotating the rotary table. And designing an installation structure of a disassembling tool on the end face of one threaded end of the rotary table bolt. Therefore, in daily inspection, after a certain turntable bolt is found to be broken, the turntable bolt is turned to be above the rack process hole. And (4) penetrating the disassembling tool through the fabrication hole, installing the disassembling tool on the broken bolt stub, and rotating the disassembling tool to unscrew the rotary table bolt stub. After the qualified turret bolt fittings are installed, necessary inspection is performed and the repair operation is completed. The utility model provides a scheme can show and reduce and restore dismouting work load.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
FIG. 1 is a schematic structural view of a current cutting slewing mechanism;
FIG. 2 is a schematic structural view of the cutting rotary mechanism of the present invention;
FIG. 3 is a schematic view of a threaded end of a bolt of the turntable;
fig. 4 is a schematic view of a removal tool.
Detailed Description
The invention will be further explained below with reference to specific embodiments, without limiting the invention.
A specific embodiment of the present invention is shown in fig. 2, the cross-section is the transverse middle plane of the heading machine, passing through the axis of revolution. This embodiment provides an improved design of the gantry and turret bolts. The modified frame is marked as part number (6), and the modified turntable bolt is marked as part number (7). A through fabrication hole is designed on the frame (6), the distance from the axis of the fabrication hole to the rotation axis is equal to the radius of a distribution circle of the rotary table bolt (7), and sufficient space is arranged below the fabrication hole to implement disassembly operation. Thus, by rotating the turntable (5), all the turntable bolts (7) have the opportunity to appear right above the fabrication holes of the frame (6). An internal hexagonal hole is formed at one end of the thread of the rotary table bolt (7) (as shown in figure 3). And if the rotary table bolt (7) is broken, the broken bolt is turned to the position above the process hole of the rack (6). The removal tool (8) is a long-handled allen wrench, as shown in fig. 4. A dismounting tool (8) penetrates through a process hole of the rack (6), and the outer hexagonal structure of the dismounting tool (8) is inserted into an inner hexagonal hole of the broken turntable bolt (7), so that the residual section of the dismounting tool can be screwed out of the slewing bearing.
The utility model also provides a entry driving machine (not shown in the figure) with above-mentioned cutting rotation mechanism.
The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
Claims (2)
1. The utility model provides a cutting rotation mechanism for entry driving machine, its characterized in that: rotation mechanism includes frame (6), slewing bearing (3), slewing bearing bolt (2), revolving stage (5), revolving stage bolt (7), and frame (6) are together fixed with slewing bearing bolt (2) for slewing bearing (3) outer lane, and revolving stage (5) are together fixed with slewing bearing bolt (7) for (3) inner circle, just there is the fabrication hole to the position of revolving stage bolt (7) on frame (6), rotate revolving stage (5), and revolving stage bolt (7) can turn to the top of frame (6) fabrication hole, there is the structure of installation extracting tool (8) on the terminal surface of revolving stage bolt (7) screw thread one end.
