Abstract
The utility model discloses an end cap fixed three-blade hob with an abrasion detection function, comprising blades, a cutter body, an end cap and a shaft, wherein the blades are installed on the cutter body; the cutter body is installed on the shaft; three hobs are connected by using the end cap; the middle part of the shaft is provided with a horizontal main path; the horizontal main path is respectively provided with a vertical branch in the positions of the three hobs; the vertical branches lead to the end parts of the blades; the end part of the horizontal main path is connected with an oil delivery pipe through a pipe connector; the oil delivery pipe is connected with a hydraulic rotating connector and an oil delivery system and then is connected with a pressure sensor at the terminal. According to the end cap fixed three-blade hob with the abrasion detection function, disclosed by the utility model, an oil pressure detection mechanism is designed and applied to the hob, and used for detecting abrasion situation of the hob according to the data displayed by the pressure sensor, so that the worn-out hob can be more accurately picked out to be replaced and the cost loss is reduced.
Description
Technical field
The utility model relates to a kind of shield machine with three sword hobboing cutters, relates in particular to a kind of fixed three sword hobboing cutters of end cap that the abrasion detection function is arranged.
Background technology
Three sword hobboing cutters are simple in structure in the shield cutter, broken cutters that the rock amount is big, efficiency of breaking rock is high; Be mainly used in the fragmentation, hard rock; Three sword disk cutters then have higher efficiency of breaking rock with it, are widely used as the center cutter into shield machine, and the operating mode of shield-tunneling construction is changeable; Often need change, to guarantee efficiency of construction and construction quality shield structure center cutter cutter.But the fixed three sword hobboing cutters of shield machine end cap do not have the abrasion detection function at present, so just can accurately this three swords hobboing cutter that wear and tear not chosen, in order to guarantee efficiency of construction and quality; The general method of replacement in batch that adopts; Some three sword hobboing cutters that do not damage also have been replaced, and have so just caused the wasting of resources, need to propose a kind of three sword hobboing cutters with abrasion detection function; Reach when maintenance and only replace the three sword hobboing cutters that worn and torn, keep the purpose of unworn not sword hobboing cutter.
The utility model content
To above defective, the utility model provides a kind of fixed three sword hobboing cutters of end cap that the abrasion detection function is arranged, and has solved the problem that existing hobboing cutter can not detect the hobboing cutter degree of wear in real time.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of fixed three sword hobboing cutters of end cap that the abrasion detection function is arranged comprise blade, cutter hub, end cap and axle, and blade is installed on the cutter hub; Cutter hub is installed on the axle, connects with end cap between three hobboing cutters, and the axle middle part has horizontal main line; Horizontal main line respectively has a vertical branch road three hobboing cutter positions, and vertically branch road leads to the blade end, and end, horizontal main line links to each other with petroleum pipeline through union; Petroleum pipeline links to each other with pressure sensor at the terminal after connecting hydraulic rotary joint and fuel transfer system.
Said vertical branch road is a plurality of, leads to the different directions of blade.
The utility model design oil pressure testing agency is applied in the hobboing cutter, can detect the hobboing cutter abrasion condition according to the video data of pressure sensor, can more accurately the hobboing cutter that weares and teares be chosen and change, and has reduced the cost loss.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model.
Among the figure:
1, vertical branch road; 2, end cap; 3, blade; 4, cutter hub; 5, horizontal main line; 6, union; 7, axle; 8, hydraulic rotary joint; 9, pressure sensor; 10, fuel transfer system.
The specific embodiment
As shown in Figure 1, show the described a kind of embodiment that the fixed three sword hobboing cutters of end cap of abrasion detection function are arranged of the utility model, comprise blade 3, cutter hub 4, end cap 2 and axle 7; Blade 3 is installed on the cutter hub 4, and cutter hub 4 is installed on the axle 7, connects with end cap 2 between three hobboing cutters; Axle 7 middle parts have horizontal main line 5; Horizontal main line 5 respectively has a vertical branch road 1 three hobboing cutter positions, vertically branch road 1 leads to blade 3 ends, and 5 ends, horizontal main line link to each other with petroleum pipeline through union 6; Petroleum pipeline links to each other with pressure sensor 9 at the terminal after connecting hydraulic rotary joint 8 and fuel transfer system 10.
The utility model design oil pressure testing agency is applied in the hobboing cutter, can detect the hobboing cutter abrasion condition according to the video data of pressure sensor, can more accurately the hobboing cutter that weares and teares be chosen and change, and has reduced the cost loss.
Claims (2)
1. the fixed three sword hobboing cutters of end cap that the abrasion detection function is arranged comprise blade, cutter hub, end cap and axle, and blade is installed on the cutter hub; Cutter hub is installed on the axle; Connect with end cap between three hobboing cutters, it is characterized in that: the axle middle part has horizontal main line, and horizontal main line respectively has a vertical branch road three hobboing cutter positions; Vertically branch road leads to the blade end; End, horizontal main line links to each other with petroleum pipeline through union, and petroleum pipeline links to each other with pressure sensor at the terminal after connecting hydraulic rotary joint and fuel transfer system.
