Abstract
The invention relates to a novel torque meter used for a sludge concentration mud scraper. The torque meter comprises a base seat 1, a rack 2, a main drive gear 3, an analog signal generating mechanism 4, a cam 5, an auxiliary drive gear 6, a travel switch 7, a main fixed plate 8, an auxiliary fixed plate 9, a pointer 10, a panel 11, a shell 12, a central shaft 13, etc.. The torque meter overcomes the defect that the traditional torque meter can only output switching value and can not output analog quantity, and the torque meter can output the switching value and the analog quantity as well, thus the continuous torque signals can be sent to a central control room remotely so as to realize the remote monitoring and the interchanging with the original device, and the application is convenient.
Description
Technical field
The present invention relates to the torque gauge that uses on the mud thickener in a kind of sewage treatment area.
Background technology
The present employed torque gauge of mud thickener, adopt by the rotation of rack drives pointer more, the indication angle, control the break-make of travel switch by being installed in cam on the axle, so that export several switching value contacts (being generally three contacts) in different angles, control the lifting and the warning of mud scraper motor with this.
The shortcoming of this torque gauge is: because the locus is limit, torque gauge inside can only be installed three travel switches at most, that is to say, each torque gauge can only be exported three switching value signals at most, wonder the angle value of torque gauge, can only be by the post operation worker to field observation, and the mud thickener generally is installed on the high platform, very inconvenient up and down.And centralized control room also can't come the lifting of mud scraper motor is controlled according to the size of torque value.
Summary of the invention
The technical problem to be solved in the present invention is under the prerequisite of physical dimension that does not change former torque gauge and installation dimension, that is under the prerequisite that guarantees torque gauge interchangeability, by change to its inner structure, increase its function, make it promptly keep original function, can export reflection moment of torsion continually varying analog quantity again, thereby solve above-mentioned shortcoming effectively.
For addressing the above problem, the present invention designs a kind of novel torque gauge that is used on the sewage disposal device mud thickener, form by base, tooth bar, main drive gear, simulating signal generating mechanism, cam, auxiliary driving gear, travel switch, main fixed head, secondary fixed head, pointer, panel, shell etc., it is characterized in that main fixed head is screwed on base, tooth bar links to each other with main drive gear, pays transmission gear for two and links to each other with main drive gear; Secondary fixed head links to each other with main fixed head by screw and sleeve pipe, and simulating signal generating mechanism and travel switch are fixed on the secondary fixed head, and cam is fixed therein on the axle of an auxiliary driving gear, and cam is along with the rotation of auxiliary driving gear; The central shaft of simulating signal generating mechanism is along with the rotation of opposite side auxiliary driving gear; Panel links to each other with main fixed head by screw and sleeve pipe, and pointer links to each other with the axle of the auxiliary driving gear that is connected cam by little spring.
The simulating signal generating mechanism is equipped with in torque gauge inside as described, it is characterized in that: the central shaft rotation of transmission gear rotating band dynamic simulated signal generating mechanism, the analog output signal of simulating signal generating mechanism changes between 4-20mA.
Description of drawings
Concrete structure of the present invention is provided by following examples and accompanying drawing.Accompanying drawing 1 is the structural representation of torque gauge of the present invention, also is simultaneously that specification digest is with scheming.
Embodiment
Specify the present invention below in conjunction with Figure of description and propose detail and working condition.
Torque gauge comprises: parts such as base 1, tooth bar 2, main drive gear 3, simulating signal generating mechanism 4, cam 5, pair transmission gear 6, travel switch 7, main fixed head 8, pair fixed head 9, pointer 10, panel 11, shell 12.
When the moment of torsion of mud thickener changes, the slide bar that drives the torque gauge tooth bar produces under the effect of big spring and moves, at this moment, tooth bar 2 is along with moving, the rotation of the mobile drive main drive gear 3 of tooth bar 3, the rotation of main drive gear 3 drive two rotations 6 of paying transmission gear simultaneously, also rotation thereupon of pointer 10 simultaneously, the rotation of pointer is corresponding with the scale value on being installed in the panel of paying on the fixed head 9 11, can read torque value.Along with the rotation of main drive gear, be installed in cam on one of them pair driving gearshaft according to design load, make the travel switch action that is installed on the main fixed head 8, like this, just can export switching value at different torque values and come main frame is controlled and protected; Simultaneously, the central shaft 13 that is installed in the simulating signal generating mechanism 4 on the main fixed head 8 is under the drive of another pair transmission gear 6, also along with rotation, rotation along with the central shaft of simulating signal generating mechanism 4, be installed in its inner circuit, size according to this anglec of rotation changes the analog quantity of its output automatically, so just there is a continuous analog signal (between the 4-20mA) to reach switch board or centralized control room, according to the continuous variation of torque value main frame monitored with convenient.Pass through said structure, novel torque gauge has overcome traditional torque gauge can only export switching value, and can not export the shortcoming of analog quantity, accomplish to export switching value, can export analog quantity again, thus make continuous torque signal can teletransmission to central control room, to realize the teletransmission monitoring, and can realize can exchanging with existing equipment, it is convenient to use.
