Vertical roller grinder in grinding system with the closely combination such as feeder, powder concentrator, dust-precipitator, constituent streaming system, form air flow system with preheater, high-temperature blower, powder concentrator, cyclone separator, circulating fan, dust-precipitator etc., be very important multi-functional equipment of technique grinding system simultaneously.As a technological equipment, it is being born oven dry to material, is grinding, selecting the task of powder, thereby controls grinding roller by hydraulic control rocking arm, gives the certain pressure of grinding roller, makes it and an abrasive structure system of mill composition.Due to the bed of material of material can not guarantee in process of lapping consistent all the time, so the roller position of grinding roller will be subject to the impact of thickness of feed layer, in continuous variation.Different materials, the thickness of the bed of material also has certain difference.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of vertical rolls grinding roller position induction measurement devices is provided, can be easily installed in the variation that Vertical Mill is outside and can measure the inner roller of Vertical Mill position, by electrical control, have that cost is low, installation and debugging convenient, degree of accuracy advantages of higher.
For realizing above technical purpose, the utility model will be taked following technical scheme: a kind of vertical rolls grinding roller position induction measurement devices, described vertical roller grinder comprises rocker arm shaft, this rocker arm shaft changes and rotates with grinding roller roller position, comprise with the coaxial rotating shaft being connected of rocker arm shaft, be set in bearing (ball) cover in rotating shaft, be fixed on bearing (ball) cover outside inductive component, be set in rotating shaft and with rotating shaft rotation Hall switch assembly and stifle; Described inductive component comprises sensor block supporting seat and the sensor block of distributing installation on sensor block supporting seat; Described Hall switch assembly comprises Hall switch supporting seat and Hall switch, and described Hall switch is arranged on Hall switch supporting seat and with corresponding sensor block induction and generates signal, transfers out by binding post; Described stifle is located at the outermost of rotating shaft and is connected with sensor block supporting seat.
As preferably, described sensor block supporting seat is annular, and outer edge is provided with annular boss; Sensor block is evenly distributed in the inner side of annular boss; Described stifle is fixed on annular boss and forms seal cavity, and Hall switch assembly is included.
As preferably, the contact-making surface of described bearing (ball) cover and rotating shaft is provided with sealing ring.
As preferably, comprise 5 sensor blocks, these 5 sensor blocks are evenly located at the first half of sensor block supporting seat, simultaneously correspondingly on Hall switch supporting seat are provided with 5 Hall switch.
According to above technical scheme, compared with prior art, the utlity model has following advantage: the variation that can be easily installed in vertical roller grinder outside and measure the inner roller of Vertical Mill position, in mill, roller position is the variation of the bed of material, pass to electric control system with certain induced signal, for electric control system; There is the advantages such as simple in structure, cost is low, safe and reliable, installation and debugging are convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of vertical rolls grinding roller described in the utility model position induction measurement devices;
Fig. 2 is the structural representation of inductive component described in the utility model.
Wherein, rocker arm shaft 1, rotating shaft 2, bearing (ball) cover 3, stifle 4, sensor block supporting seat 5, sensor block 6, Hall switch supporting seat 7, Hall switch 8, binding post 9, sealing ring 10, screw 11, bearing baffle 12, nut 13.
The specific embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Explain the technical solution of the utility model below with reference to accompanying drawing.
As shown in Figure 1, for the mounting structure schematic diagram of Novel roller level detecting apparatus, sequence number screw is for fixed structure, being convenient to installation and removal uses, binding post is used for transmitting sensed data, axle is the axle of roller level detecting apparatus, nut is in order to fix Hall switch supporting seat in rotating shaft, sealing ring is in order to the gap of sealing pivot and bearing (ball) cover, Hall switch supporting base is that Hall switch is installed, and be fixedly mounted in rotating shaft, in the time of the induction of itself and sensor block, can export corresponding induced signal, stifle is in order to the position of fixing sensor block, and overall structure is sealed, sensor block is a kind of sensing element, in order to induced signal, sensor block supporting seat is in order to fixing sensor block, an induction installation of above structure composition, because the variation of roller position causes the rotation of rocker arm shaft, rocker arm shaft is connected with rotating shaft, and the rotation of rotating shaft makes the induction of different Hall switch with corresponding sensor block, spreads out of corresponding signal after induction.
As shown in Figure 2 attached, described inductive component is used for spacing structural representation:
(1) be about to be about to be sensed as initial position with sensor block 1 take Hall switch 1 and now establish 0 as 0 ° of α, now position is zero-bit, the material thickness of corresponding this position is partially thin, roller position is lower, in process by zero-bit rotation 0～α 1, now Hall switch 1 and sensor block 1 can be responded to, and remaining Hall switch and corresponding sensor block are not responded to, only have Hall switch 1 to spread out of induced signal, this process is made as stopping means low level;
