Heretofore described oil cylinder design optimizes cylinder structure and seal form under the premise of easy to process,
Make piston 25, plunger 18 surface roughness be 1.6, processing easily reach requirement, reduce cost.Oil cylinder both ends by axis pin with
Holder 5 and connecting rod 11 are slidably connected, and can adapt to brake disc beat automatically, make brake disc not by unbalance loading.
The present invention brakes large-sized grinder using caliper brake, by controlling operating oil pressure size, adjusts jaw type
The method of 23 release spring power of brake disk spring changes size of the caliper brake brake shoe 1 to the brake force of brake disc, rises
To the effect of regulating brake force square, process of braking and declutch is by solenoid valve control, to ensure steady, work when grinding machine braking
Oil pressure is no more than 14MPa, flow 22.5L/min.Further, the gap between brake disc and brake block 1 be 3~3.5mm,
Can adaptive brake disc beat, brake force can reach 300~500T when caliper brake of the present invention closes a floodgate, and 6 front end of tong arm with
Oil cylinder front end is located at by axis pin B4 and axis pin C9 on holder 5 respectively, and oil cylinder rear end and connecting rod 11 pass through axis pin D12 and pin respectively
Axis E13 is in the endoporus of 6 rear end of tong arm, and plunger 18 drives connecting rod 11 and tong arm 6 to act to forward and backward movement, and lock boots 2 can be along holder
5 endoporus move back and forth.Piston 25 and plunger 18 are located in oil cylinder, and disk spring 23 is on guide rod 24 and passes through disc spring pad 22
It is contacted with 25 outer end face of piston.Compared with existing brake technology, the structure of brake is not only simplified, and reduces cost.Together
When the present invention in braking process have automatic compensation function, be not required to manually adjust, tong arm 6 can with holder 5 coordinate
Axis pin on slide, the +/- 10mm of brake disc beat can be adapted to automatically, solve ordinary disc-type brake device because moving back away from adjusting improper production
Phenomena such as raw brake disc both sides brake force is uneven.Shaking in brake shoe uneven wear and braking process can be effectively prevented from
It is dynamic, to improve the utilization rate of brake shoe, reduce the loss of brake shoe.
The present invention is to lean on 23 precompressed dynamic braking of disk spring, and oil pressure releases braking, the brake that brake force acts in an axial direction.
When grinding machine is braked, the precompression of disk spring 23 forces piston 25 and plunger 18 to act, and 11 He of connecting rod is driven by related axis pin
Tong arm 6 acts, and the brake block on lock boots 2 is released, makes the brake disc of brake block and cylinder, and generate normal pressure, is formed
Frictional force and generate braking.Grinding machine declutch operation when, charged pressure oil, piston 25 compress disk spring 23 again in oil cylinder chamber,
And drive connecting rod 11 and the action of tong arm 6 to move forward by plunger 18, to make brake block leave brake disc, release brake force
(declutching).When grinding machine normal operation, the completely upper pressure of oil cylinder, brake is opened a sluice gate completely.When mine power failure or grinding machine bearing profit
When sliding failure, brake hydraulic system is closed a floodgate with certain speed pressure release, brake, and grinding machine stops turning in a short period of time
It is dynamic, and imbalance state at full capacity can be stopped at.When replacing liner plate and maintenance, grinding machine is with fixed slow rotation to preset angle
Degree, braking system can provide fast braking to the grinding machine of rotation.
Heretofore described cylinder seal uses 31 form of high-pressure type DSM combination sealings, close by multiple structure of sealing lip
Seal it is efficient, when system pressure increases, " u "-shaped circle to main seal ring exert a force, wherein guide ring has the function of anti-extrusion, is shaking
Sealing effect is good under dynamic and shock loading.Plunger 18 is sealed into the structure that Basel adds guide ring, can be obtained under low pressure
Obtain good sealing performance so that cylinder efficient is relatively reliable.
Cylinder structure is described as follows：
1, the sealing structure form that this structure uses, primary seal are DSM combination sealings, and plunger is sealed into Basel and adds guiding
The structure of ring, supports, and sealed reliable, frictional resistance is small, meets rate request；
2, piston 25, plunger 18 surface roughness be 1.6, processing easily reach requirements, be suitble to make by oneself；
3, guide rod 24 is increased, support is improved, but also the internal diameter processing roughness of cylinder 10 reduces, turnery processing
It can reach requirement；
4, when requiring beat in work, oil cylinder can be automatic to adapt to brake disc beat by axis pin relative motion, works as recovery
Nominal situation oil cylinder realizes automatic centering.
The present invention has following superiority：
1. the brake force of spring can compensate for the fair wear and tear of brake shoe；
2. operating pressure is low, the service life of sealing and part can be extended；
3. brake quantity is few, reduces installation difficulty and reduce leakage point;
4. each brake has large capacity high pressure filter, ensure system clean；
It is opened a sluice gate 5. each brake has individual hand-operated valve that can quickly turn off holding, there is individual safe valve protection system
System safety.
6. integrated levels are high, difficulty of processing and production procurement cost are reduced.
7. manufacture installation, working service are more prone to convenient；
8. keeping staff's operation and maintenance very intuitive, while security performance greatly improves.
The present invention is also applied for the similar operating mode application of other products simultaneously.
Further, heretofore described oil cylinder could alternatively be cylinder.
Part not in the detailed description of the invention is the prior art.
The embodiment selected herein for the open purpose of the present invention, is presently considered to be suitable, still, Ying Liao
Solution belongs to all changes and the improvement of the embodiment in this design and invention scope the present invention is intended to include all.
