Description
Technical Field
The utility model relates to a mechanical type brake equipment technique specifically is an automatic accurate clearance adjustment device of full mechanical type disc brake. The device is used for automatically and relatively precisely adjusting the abrasion clearance between the brake pad and the brake disc, the adjusting function is adjusted while running, the effectiveness and the safety of the original brake device are guaranteed, the installation size can be exchanged with the original piece in the same way, and the device is suitable for various disc brake devices.
Background
The disc brake device is widely applied to mechanical equipment, and the braking reliability of the disc brake device directly influences the safety of the whole operation machine and field personnel. In the process of executing braking, the disc brake device generates friction between the brake pad and the brake disc, the brake pad is worn quickly, and after the brake pad is worn, the gap between the brake pad and the brake disc is increased. The stroke of the brake pad for executing the braking task is increased, the braking time is prolonged, and the effectiveness of the braking function and the safety of equipment are directly influenced. How to compensate the clearance between the brake block and the brake disc of the disc brake device in time becomes a very important difficulty which must be overcome.
At present, two common schemes are used for realizing the compensation of the clearance between the brake block and the brake disc of the disc brake of the oil drilling machine. The first scheme adopts a screw spring type regulator, and adopts a nut on a manual regulating screw to compensate the clearance between a brake pad and a brake disc. However, this method has a large limitation: firstly, manual adjustment is needed, the labor intensity is high, and unsafe factors are more; and secondly, the brake pad is quickly abraded during quick tripping construction, the gap between the brake pad and the brake disc is quickly increased, and the compensation gap needs to be adjusted in time. The compensation clearance is adjusted manually and obviously lagged; thirdly, frequent adjustment is needed, operators on site may have negligence and untimely adjustment, and the opportunity of adjusting the gap is delayed.
The second scheme is that the Chinese patent application number is CN00226833, which is named as a clearance automatic compensation brake cylinder, and provides a clearance automatic compensation brake cylinder which adopts a double-hydraulic-cylinder form. The structure is as follows: it has large and small pistons and a variable diameter cylinder body which is formed by combining two cylinder bodies with different cylinder diameters into a whole. The large piston and the limiting spacer bush are sequentially arranged in the large diameter of the reducing cylinder body; the small piston is opposite to and closely attached to the large piston and is arranged in the small cylinder diameter of the reducing cylinder body. Meanwhile, the vertical distance between the bottom surface of the large piston and the inner platform of the reducing cylinder and the vertical distance between the upper surface of the large piston and the end surface of the limiting spacer sleeve are equal. The advantages are keeping original brake sensitive, safety and reliability. However, the problems with this structure are manifested in: firstly, the different original parts cannot be interchanged due to the change of the geometric dimension, and the rearrangement is difficult; secondly, the braking forces at two ends are different due to the difference of the diameters of the two cylinders; the structure of the hydraulic cylinder is complex, the maintenance is difficult, and the service life of the hydraulic cylinder is shortened compared with that of an original part; fourthly, the small cylinder shaft is unstable in suspension when not working, and the working reliability is low.
Many patents, new technologies and new products related to disc brake devices have improved structures and functions, but most of the disc brake devices are applicable to a certain device, and still more innovations are needed in the aspects of universality, automaticity and precision. Therefore, a disc brake device with a simpler structure, safer and more reliable operation, more timely and more precise automatic performance and wear clearance adjustment is needed.

And a contact point is arranged below the rightmost pawl of the pawl assembly, the contact point is arranged in a ratchet groove which is positioned on the ratchet bar and is positioned on the right side of the rightmost pawl combination of the pawl assembly, and the distance between the ratchet groove and the rightmost pawl of the pawl assembly is the standard for replacing parts or scrapping of the brake device, namely the distance between a brake disc and a brake pad is worn to the allowable maximum clearance and is 5-8 mm. When the rightmost pawl moves into the ratchet groove and triggers the contact, namely the maximum allowable abrasion clearance is reached, the alarm part is started to send out an alarm signal to remind an operator of replacing related parts of the brake device in time.
The utility model discloses full mechanical type disc brake automatic accurate clearance adjustment device's theory of operation:
under the condition of no braking, a set initial gap B is left between the brake disc and the brake pad1. The initial gap B1Through lever transmission, an initial clearance C before the piston shaft runs is formed at the neck of the piston shaft, namely the initial running overcomes the minimum distance, so that the brake pad is contacted with the brake disc. When the brake device works, the brake disc is driven by the host to rotate, the brake disc is braked by the oil cylinder after losing power, the piston shaft pushes the lever to drive the brake pad to brake the brake disc, and the abrasion gap between the brake disc and the brake pad is gradually increased in use.
As the abrasion between the brake disc and the brake pad is gradually increased, when the adjusting device starts to work, the piston and the piston shaft are pushed to move forwards by pressurized oil injected into the oil cylinder, the oil cylinder moves backwards in the opposite direction, and the pawl 5 on the pawl seat assembly 4 moves forwards relatively on the ratchet of the ratchet bar. The n pawl combinations of the pawl assemblies on the ratchet bar are sequentially arranged at the positions with smaller distance of each H/n, so when a gap with the thickness of H is worn each time, one pawl combination is required to be arranged on the ratchet bar in the process of moving forwards, only one pawl of the pawl combination falls into the ratchet, when the piston shaft, the lever and the brake pad are pulled by the reset spring to reset, the pawl can only move forwards on the ratchet bar, the pawl combination and the ratchet prevent the piston shaft and the lever from reducing the reset by the width of H during the reset, and the brake pad increases the reset by the width of H under the action of the lever, so that a gap with the thickness of H between the brake pad and the brake disc is reduced by the thickness of H, and the gap with the thickness of H, which is increased by the abrasion of the brake pad and the brake disc, is timely adjusted. Because the oil cylinder and the piston move oppositely and equidistantly, the levers at the left end and the right end and the brake pad generate the same displacement change, and the same synchronous adjustment compensation is carried out on the gaps at the left side and the right side of the brake disc.
Because the moving width H of each ratchet is controlled by n pawl combinations, every time a wear gap with the width of H/n is formed, a pawl falls into the ratchet to perform reset control, and the adjusting gap is not controlled by the wear until a ratchet width, namely the width of H is formed. This greatly refines the accuracy of the adjustment of the wear gap. In practical design, the ratchet width H can be designed to be smaller according to the requirements of equipment, the number n of the pawl combinations is designed to be larger, namely the smaller the H value is, the larger the n value is, the more precise the adjustment of the abrasion clearance can be realized, and the requirements of various equipment on braking precision can be met.
