Abstract
The utility model relates to an over-torque protection system of a sludge sucking and scraping machine. The over-torque protection system comprises a driving bracket, a connecting rod, a tension or pressure sensor, a sensor fixing seat and a multifunctional measuring meter, wherein a connecting plate fixed on a reducer is connected with one end of the connecting rod by an adjustable shifting fork and can adjust length and pre-tightening force; the other end of the connecting rod is fixed with the tension or pressure sensor to convert torque applied to the reducer into tension or pressure which is then transferred to the tension or pressure sensor; the sensor converts received tension or pressure signals into electrical signals which are then transferred to the multifunctional measuring meter; and the multifunctional measuring meter outputs and feeds back control signals to a control box of the sludge sucking and scraping machine. The over-torque protection system has the technical effects that through the tension or pressure sensor, the torque and stress of the driving system of the sludge sucking and scraping machine can be accurately measured and displayed, and serious failures such as the damage of the driving mechanism, the damage of the sludge sucking and scraping system and a bridge can be stably and effectively avoided under an overload condition.
Description
Technical field
The utility model relates to a kind of over-torque defense system of scraping and sucking machine.
Background technology
Along with developing rapidly of industrial and agricultural production and improving constantly of living standards of the people, the problem of short water supply and the discharging of sewage stably reaching standard is more and more outstanding.Under the new policy of national sustainable development, environmental protection has been subject to governments at all levels and national people's great attention, and the processing of sewage being carried out efficient stable is increasing with the importance of the environment that to protect mankind is depended on for existence.Scraping and sucking machine is the large-scale key equipment in sewage treatment plant, and scraping and sucking machine is stable, safety, efficiently move guarantee sewage treatment plant and normally run, and guarantees that stable water outlet is up to standard; Therefore extremely important to the protection of scraping and sucking machine, especially to the protection of transmission system, safety pin or elastomer torque defense system are adopted in the protection of prior art multi-motor-drive system more; The problem of its existence of safety pin protection system is: when safety pin is sheared power and destroys, shaft joint also is damaged, maintenance cost and cycle have been improved, affect sewage disposal system, in addition due to the difference of safety pin at aspects such as material, heat treatments, the power that safety pin is cut off is often also inconsistent, might damage transmission system like this, cause reductor, even whole drive system is scrapped, and has a strong impact on the normal operation of sewage disposal; The problem of its existence of elastomer torque defense system is: can't protect moment of torsion by accurate adjustment; resistance to corrosion is poor; less stable; the elastomer torque defense system can't intuitively show current torque protection value, scraping and sucking machine generally all out of doors, corrosiveness of the environment of living in is larger; the easy corrosion of elastomer and connector; cause original torque value of setting to change, torque setting needs professional and specific purpose tool just can carry out in addition, and torque value changes or lost efficacy and can not in time find.
Summary of the invention
The deficiency of the aspects such as the utility model mainly solves short, inconvenient operation of the poor stability, the service life that exist in prior art, adjustment and maintenance difficulty, maintenance period is long, corrosion resistance is poor, reaction is insensitive.
The main technical schemes of this programme is: the over-torque defense system of scraping and sucking machine, and it includes driving arm, connecting rod, pulling force or pressure sensor, sensor holder, multi-functional measurement instrument; Be fixed on the connecting plate on reductor, be connected with an end of connecting rod by regulating shift fork, and adjustable length and pretightning force, the other end of connecting rod and pulling force or pressure sensor are fixed, the torque axis that is subject on reductor is changed into draw, pressure passes to sensor, sensor converts drawing of receiving, pressure signal the signal of telecommunication to and gives multi-functional measurement instrument, and multi-functional measurement instrument feeds back the output control signal again to the scraping and sucking machine control cabinet.
The technique effect of this device is: this device is by pulling force, pressure sensor; scraping and sucking machine drive system moment of torsion and stressing conditions can be accurately measured and show, effective protection equipment can be stablized in the situation that driving mechanism does not occur overload damages and scrape and inhale the catastrophe failures such as mud system and crane span structure are damaged.
Description of drawings
1, with the suction dredge of high accuracy torque defense system;
2, high accuracy torque defense system figure.
Specific embodiments
As Fig. 2: 1, reductor, 2, connecting plate, 3, regulate shift fork, 4, connecting rod; 5, draw, pressure passes to sensor, 6, sensor holder, 7, polymeter;
As Fig. 1: 8, output shaft, 9,2-level reducer, 10, electric control box, 11, service bridge, 12, dredging tube, high accuracy torque defense system 13;
be provided with high accuracy torque defense system 13 on existing 2-level reducer 9, high accuracy torque defense system 13 is the connecting plates 2 that are fixed on reductor 1, be connected with an end of connecting rod 4 by regulating shift fork 3, and adjustable length and pretightning force, the other end of connecting rod 4 and pulling force or pressure sensor 5 are fixing, the torque axis that is subject on reductor 1 is changed into draw, pressure passes to sensor 5, sensor 5 is drawing of receiving, pressure signal converts the signal of telecommunication to and gives multi-functional measurement instrument 7, multi-functional measurement instrument 5 feeds back the output control signal again to scraping and sucking machine control cabinet 10,
During scraping and sucking machine work, the road wheel of dredging tube or service bridge produces a reaction force to reductor, and this reaction force is delivered to and draws or pressure sensor.If scraping and sucking machine is worked under rated load, its moment of torsion is converted into pressure less than the set-point of multifunction instrument, and protector is failure to actuate; When scraping and sucking machine is subject to surpassing rated load, moment of torsion surpasses setting value, the power on sensor of being delivered to is greater than the set-point of multifunction instrument, sensor feeds back to multifunction instrument again, the multifunction instrument output alarm signal is to scraping and sucking machine control cabinet 10, scraping and sucking machine control cabinet 10 will cut off the reductor power supply after receiving alarm signal, and pending fault is pressed SR after getting rid of, and system restarts allowing.
