Description
Technical field
The present invention relates to shield machine jaw crusher fields, particularly relate to a kind of jaw crusher angle monitor device.
Background technology
In current constructing tunnel, Shield Construction Technique is with its high degree of automation, working security is good, construction speed
Soon, the advantages such as small, at low cost are polluted, are gradually used widely.Slurry balance shield machine is because of its unique high operating pressure, the palm
The advantages such as sub- face accurate pressure control, which are widely used in, wears in the Tunnel Engineering such as river, over strait, shallow earthing.
Slurry balance shield machine is divided into two kinds of patterns of direct control type and indirect control formula.Indirect control formula slurry shield gas
Pad orlop portion is disposed with jaw crusher.Jaw crusher is opened and closed by oil cylinder expanding-contracting action, band moving jaw plate to reach broken
The purpose of rock.The main function of jaw crusher is to be crushed the big grain size rock for entering air cushion storehouse in time, to ensure
Dregs can be discharged by plasma discharge pipeline outside hole；Simultaneously jaw crusher also have agitating function, can to air cushion orlop portion's dregs into
Row stirring reduces the stifled stagnant row's problem in storehouse caused by dregs deposition.
Since jaw crusher is located at air cushion orlop portion, for long period of soaking inside mud, working environment is extremely severe, by rock
The shock of the dregs such as stone or the abrasion of sand, crusher are one of the components that slurry shield is easiest to damage.It is especially broken
Often there is the problems such as oil cylinder oil leak in actual use in Oil cylinder, oil cylinder, to influence the use of crusher, Jin Erzhi
Connect the driving speed for affecting shield machine.The condition of broken Oil cylinder commutation is that oil pressure reaches maximum pressure or reaches the limit of row
Journey state, if oil cylinder is without the device of monitoring stroke in real time, must just reach maximum pressure every time could recycle, in this way
Oil cylinder frequently works in a high voltage state will greatly shorten its service life, while will also result in frequently to oil pipe and connector
Impacting with high pressure causes oil pipe and connector Leakage.Since crusher works under Pressure Slurry environment, operating personnel can not be straight
Connect observe its stretching state, be to embed stroke sensor in oil cylinder in conventional manner, stroke be monitored, oil cylinder will
The stroke that reaches capacity is recycled before, but stroke sensor is easily damaged, and maintenance difficult after damage；Another side
Formula is that the oil inlet quantity of oil cylinder is monitored by flow sensor, and to calculate the stroke state of oil cylinder, but there are hydraulic oil to let out
The problems such as dew or local losses, causes to measure not accurate enough.So needing a kind of reliable intuitive monitoring jaw crusher angle
Device, to judge the stroke state of oil cylinder.
Invention content
The present invention proposes a kind of jaw crusher angle monitor device, and solving reliably intuitively to carry out crusher
The problem of operating angle monitors.
The technical proposal of the invention is realized in this way：A kind of jaw crusher angle monitor device, including hydraulic cylinder,
Jaw, retainer, cover board, rotary shaft, rotary encoder and rear bulkhead, hydraulic cylinder and retainer are both connected to shield machine air cushion
Orlop portion, jaw one end is flexibly connected with hydraulic cylinder, the other end is flexibly connected with retainer, and cover board is fixedly connected with jaw,
One end of rotary shaft is fixedly connected with cover board, and the other end of rotary shaft passes through rear bulkhead, rotary shaft to be flexibly connected with rear bulkhead, revolves
One end that shaft is pierced by rear bulkhead is equipped with rotary encoder, and rotary encoder is connect with control system.
Sealing element is equipped between the rotary shaft and rear bulkhead.
The hydraulic cylinder is equipped with one end of hydraulic stem and shield machine air cushion orlop portion is rotatablely connected, the hydraulic cylinder other end
Hinged with jaw, retainer is fixedly connected with shield machine air cushion orlop portion, and retainer is hinged with jaw.
The beneficial effects of the invention are as follows：A kind of service personnel is provided without storehouse is pressed into, can directly be observed in control room
The working condition of crusher, and measure accurately；Rotary shaft is mechanical connection with cover board, highly reliable, reduces monitoring device damage
Bad probability；In addition, rotary encoder is mounted on outside storehouse, repair and replacement are convenient.Therefore the device has that accuracy is strong, reliability
The features such as high, simple, easy to maintenance in real time.
Description of the drawings
In order to illustrate the embodiments of the present invention more clearly, attached drawing makees letter needed in being described below to embodiment
Singly introduce, it should be apparent that, drawings in the following description are only some embodiments of the invention, for the common skill in this field
