Abstract
The utility model discloses a fixing structure for a triangular shaft hobbing cutter with a wear display function of a shield machine. The fixing structure comprises a cutter holder, a hobbing cutter shaft, the hobbing cutter and a wedge block, wherein the section of the hobbing cutter shaft is triangular, the cutter holder is arranged on a rack, the hobbing cutter shaft is arranged in the cutter holder, the side surfaces of the hobbing cutter shaft, adjacent to the cutter holder, are matched for positioning, another side surface of the hobbing cutter shaft is contacted with one side of the wedge block, the wedge block is connected with a cylinder with threads through a bolt, and the cylinder is arranged in a cylindrical hole in the cutter holder, so that the hobbing cutter shaft is pressed and fixed in the cutter holder. In the utility model, the hobbing cutter shaft is compressed in the cutter holder by adopting the wedge block, thus not only achieving a larger operation space when the hobbing cutter is replaced, but also solving the problem that how to fix the hobbing cutter shaft in the cutter holder better when the operation space is enlarged. Therefore, the fixing structure has the advantages of being reliable to install and easy to replace.
Description
Technical field
The utility model relates to a kind of fixed structure of shield machine triangular shaft hobboing cutter.
Background technology
Shield method is the job practices of in broken rock or soil layer, tunneling tunnel with protecting cover special machinery (being shield machine); The cutterhead of shield machine is provided with cutter; It mainly is the rotation that utilizes cutterhead; Rock, soil layer etc. are ditched, rolled and fragmentation etc. by cutter, hobboing cutter is simple in structure in the shield cutter, the broken cutter that the rock amount is big, efficiency of breaking rock is high, is mainly used in the fragmentation, hard rock; The single-blade disk cutter then with its simple structure, higher efficiency of breaking rock with than the long life characteristics, is widely used in the shield machine.Yet in present shield-tunneling construction engineering, the cutter easy abrasion will be changed often; The operating space of changing cutter is narrow; Cutter is location and fixing relatively difficulty accurately, simultaneously because the influence that cutter is vibrated is bigger, causes cutter to occur phenomenon loosening and that come off easily.Need often to change because cutter is worn, therefore need have the hobboing cutter device that has the Presentation Function that weares and teares, make the staff in time change the hobboing cutter of wearing and tearing.
The utility model content
The utility model provides a kind of fixed structure of shield machine triangular shaft hobboing cutter, to solve fixing difficulty of the used hobboing cutter of present shield-tunneling construction and the problem that does not possess the wearing and tearing indication.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of fixed structure of shield machine triangular shaft hobboing cutter; Comprise tool rest, cutter shaft, hobboing cutter, wedge, bolt, the cross section of said cutter shaft is triangular in shape, and Qi Gejiao is processed into fillet; Said cutter shaft is placed in the tool rest; Said tool rest is placed on the frame, the location that cooperatively interacts, two sides that cutter shaft and tool rest are adjacent, and another side of cutter shaft contacts with a side of wedge; Said wedge links through the screwed cylinder of placing in the cylindrical hole in bolt and the tool rest, and cutter shaft is pressed abd fixed in the tool rest.
Side at the corresponding spindle nose of tool rest is offered porose; Be provided with inner chamber in blade and the axle, said inner chamber connects fuel transfer system through union, and said fuel transfer system is provided with pressure sensor; The oil injection of certain pressure is reached each blade place of cutter hub through inner chamber; When wearing and tearing appearred in blade, the leakage of oil situation will appear in hobboing cutter, and the pressure of pressure sensor meeting instant playback inner chamber changes.
The beneficial effect of the utility model is: wedge in tool rest, is pressed abd fixed in the tool rest cutter shaft through bolton, is convenient to the replacing of hobboing cutter; Be provided with inner chamber and link to each other with fuel transfer system in blade and the axle, fuel transfer system is provided with pressure sensor, can find out intuitively that the pressure of inner chamber changes, and finds out the hobboing cutter that has worn and torn accurately, having wearing and tearing and showing accurate and advantage of simple structure.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model general structure sketch map;
Fig. 2 is the sectional drawing of the utility model;
Fig. 3 is the screwed cylindrical structure enlarged drawing of the utility model.
Among the figure:
1, cutter shaft; 2, cylinder; 3, hole; 4, wedge; 5, bolt; 6, tool rest; 7, frame; 8, hobboing cutter; 9, blade inner chamber; 10, axle inner chamber; 11, hole; 12, union; 13, fuel transfer system; 14, pressure sensor.
The specific embodiment
Shown in Fig. 1 to 3, provided a specific embodiment of the utility model, among the figure; Comprise tool rest 6, cutter shaft 1, hobboing cutter 8, wedge 4, bolt 5; The cross section of said cutter shaft 1 is triangular in shape, and said tool rest 6 is placed on the frame 7, and said cutter shaft 1 is placed in the tool rest 6; Cutter shaft 1 and tool rest 6 two the adjacent sides location that cooperatively interacts; Cutter shaft 1 another side contacts with a side of wedge 4, and wedge 4 links through the screwed cylinders of placing in the cylindrical hole 3 in bolt 5 and the tool rest 2, and cutter shaft 1 is pressed abd fixed in the tool rest 6.Simultaneously, porose 11 in a side of tool rest 6 corresponding spindle noses, in blade and axle, be provided with a blade inner chamber 9 and an axle inner chamber 10, said blade inner chamber 9 is connected fuel transfer system 13 with an inner chamber 10 through union 12, and said fuel transfer system 13 is provided with pressure sensor 14.Blade inner chamber 9 is connected fuel transfer system 13 with axle inner chamber 10; The oil of certain pressure is injected; Through blade inner chamber 9 each blade place with axle inner chamber 10 arrival cutter hubs, when wearing and tearing appearred in blade, the leakage of oil situation will appear in hobboing cutter 8; Said fuel transfer system 13 is provided with pressure sensor 14, can find out intuitively that the pressure of inner chamber changes.
The utility model is owing to adopt wedge 4 to be pressed on cutter shaft 1 in the tool rest 6, and not only making has bigger operating space when changing hobboing cutter 8, has also solved the interior problem of tool rest 6 that is fixed on that how to let cutter shaft 1 more fastening when the operating space becomes big simultaneously.Owing in tool rest 6, have a hole 3, a screwed cylinder 2 is housed in the hole 3, convenient when needing to change in case connection is not fastening, therefore the utlity model has reliable installation, the advantage that is easy to change; Because said blade inner chamber 9 is connected fuel transfer system 13 with axle inner chamber 10, said fuel transfer system 13 is provided with pressure sensor 14, and oil arrives each blade place of cutter hub through blade inner chamber 9 and axle inner chamber 10; When wearing and tearing appear in blade; The leakage of oil situation will appear in hobboing cutter 8, and fuel transfer system 13 is provided with pressure sensor 14, can find out intuitively that the pressure of inner chamber changes; Find out the hobboing cutter 8 that has worn and torn accurately, have wearing and tearing and show accurately and advantage of simple structure.
