Abstract
The utility model discloses a torque measuring device which is used for a drum mechanical brake and a disc mechanical brake. The torque measuring device mainly comprises a signal measurer, an A/D converter, a CPU processor, a torque digital display, and an output alarm control device. The signal measurer is installed on a brake arm of the mechanical brake or a connecting shaft pin of a brake scotch. So, the real-time measure for the brake torque which is attained from the brake scotch be carried out, and the key component of the brake is the brake scotch. Operators can also know the operating condition of the brake, and the possibility of accidents is reduced.
Description
The utility model relates to the moment measuring device of mechanical brake, refers more particularly to the moment measuring device of drum-type, disc type mechanical brake.
At present, drum-type, disc type mechanical brake are widely used in weight-lifting equipment and the transportation device, the main brake structure of such mechanical brake is: an end of retarding spring and brake control lever flexibly connects, the other end of brake control lever and bearing flexibly connect, and brake scotch is movably connected on the brake control lever by pivot pin.During braking work, the lock torque that retarding spring produces acts directly on the brake control lever, and brake control lever passes to brake scotch by pivot pin with this lock torque again, by brake scotch this lock torque is acted on the brake wheel at last, reaches the braking purpose.To the detection of the lock torque of such drg with adjust general by some simple machine tools---as tension indicating wrench, and some simple instruments and method of inspection carry out, the object that detects is exactly the elastic force of retarding spring, whether the mode of operation that promptly can only detect retarding spring is normal, and to brake control lever, the mode of operation of brake scotch and their link can not effectively detect, when corrosion takes place for they, when wearing and tearing even fault such as stuck, the lock torque that retarding spring produces just can not be delivered to brake scotch and brake wheel effectively, and operating personal can not in time be found this situation, thereby has increased possibility of accident occurrence greatly.And above-mentioned detection means generally can only be used in production process or maintenance of equipment process, and can not the lock torque of drg be detected in real time, promptly can not in time understand the real time operation state of drg, and this has also increased possibility of accident occurrence.
The purpose of this utility model is to provide a kind of mechanical brake moment measuring device that can detect the lock torque that obtains on the brake scotch of mechanical brake in real time.
For achieving the above object, the technical solution adopted in the utility model is: described mechanical brake moment measuring device mainly comprises: signal detector, A/D converter, CPU treater, moment digital display and output alarm control setup, above-mentioned signal detector are arranged on the brake control lever of mechanical brake and being connected on the pivot pin of brake scotch.
The pivot pin sensor that pivot pin adopts the size of special ergometry that is connected of brake control lever recited above and brake scotch promptly serves as above-mentioned signal detector with this pivot pin sensor.
In order to improve accuracy of detection, further technical scheme of the present utility model is: be provided with the resistance rotary device that prevents that the pivot pin sensor from rotating between pivot pin sensor and brake control lever.
Resistance rotary device recited above is: be installed with block on brake control lever, the circular cupping of pivot pin sensor is provided with string shape plane, this string shape plane and block closed contact.
The utility model has the advantages that: because signal detector is directly installed on being connected on the pivot pin of brake control lever and brake scotch, so just can detect the critical component of drg in real time---the size of the lock torque that obtains on the brake scotch, operating personal also can in time be understood the working of brakes situation, greatly reduces possibility of accident occurrence.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the principle of work block diagram of mechanical brake moment measuring device described in the utility model;
Fig. 2 is the structural representation that the drum brake mechanism of pivot pin sensor is installed.
As shown in Figure 1, mechanical brake moment measuring device described in the utility model mainly comprises: signal detector, A/D converter, CPU treater, moment digital display and output alarm control setup; As shown in Figure 2, the main brake structure of drum-type mechanical brake comprises: retarding spring 3 flexibly connects with an end of brake control lever 2, and the other end of brake control lever 2 and bearing 6 flexibly connect, and brake scotch 4 is movably connected on the brake control lever 2 by pivot pin 1; Above-mentioned signal detector just is arranged on being connected on the pivot pin 1 of brake control lever 2 and brake scotch 4.In the present embodiment, above-mentioned connection pivot pin 1 directly adopts the pivot pin sensor 1 of the size of special ergometry, has promptly both served as the connection pivot pin with this pivot pin sensor 1, serves as above-mentioned signal detector again.
Drg is when braking work, the lock torque that retarding spring 3 produces acts directly on the brake control lever 2, brake control lever 2 passes to brake scotch 4 by pivot pin sensor 1 with this lock torque again, by brake scotch 4 this lock torque is acted on the brake wheel 7 at last, to reach the braking purpose.This shows, in braking procedure, the lock torque that retarding spring 3 produces finally all will transmit by pivot pin sensor 1, therefore, pivot pin sensor 1 can detect the working of brakes situation in real time, can detect the size of the lock torque that obtains on the brake scotch 4 in real time, after detected torque signals handled by device such as A/D converter and CPU treater, deliver on the moment digital display on the one hand and show, in time understand the working of brakes situation for operating personal, deliver to the output alarm control setup on the other hand, drg is in time controlled the incidence of reduction accident greatly.
As shown in Figure 2, in order to improve accuracy of detection, in the present embodiment, between pivot pin sensor 1 and brake control lever 2, also be provided with the resistance rotary device that prevents that pivot pin sensor 1 from rotating.Above-mentioned resistance rotary device is: be installed with block 5 on brake control lever 2, the circular cupping of pivot pin sensor 1 is provided with string shape plane, this string shape plane and block 5 closed contacts; Like this, pivot pin sensor 1 just can not rotate in the course of the work, can not influence survey precision because of the change of stress point.
The structure and the principle of work of the structure of disc type mechanical brake and principle of work and above-mentioned drum-type mechanical brake are quite similar, and moment measuring device described in the utility model equally also can be applicable to the disc type mechanical brake, repeats no more.
