Description
Technical field
The present invention relates to a kind of portable crushing plant, the rotary braking device in particularly a kind of large-scale mobile disintegrating apparatus slew gear.
Background technology
Portable crushing plant is a kind of that bulk materials is broken; And with the disintegrating apparatus of the mass transport after the fragmentation to assigned address, it has a charging hopper, one and is used for carrying the stocking conveying device of charging hopper material, breaker that is used for broken material, one to be used to transport the discharge transport of material after the breaker fragmentation, main body steel construction that is used for fastening, one being used for the running gear that equipment moves.Wherein, some equipment is more flexible for feed, between running gear and top equipment body steel construction, a slewing equipment is set, to realize the whole revolution of the relative upper body equipment of running gear; The equipment that also has is more flexible for the off-take point displacement, and a slewing equipment is set between discharge transport and equipment body steel construction, rotates to realize the relative main equipment of discharge transport.Above-mentioned two places slewing equipment co-ordination will increase substantially the operating efficiency of Crushing Station.The driver element of gyration is made up of motor, reductor, shaft coupling, brake apparatus, and revolution drives also can adopt hydraulic way to drive, because hydraulic way is complicated, so the general motor drive mode that adopts.When not needing the equipment gyration, gyration is locked through the brake apparatus in the driver element.Because slew gear is in the key structure position in disintegrating apparatus, in case the damage of components in the slew gear, not only not easy-maintaining and replacing, and directly influence the operating efficiency and the service life of disintegrating apparatus.In the prior art, general driver element place in slew gear takes braking, adopts disk brake pair to realize braking with the brake disc on the shaft coupling that motor output shaft links to each other usually.
In the above-mentioned prior art, brake apparatus be to shaft coupling that motor output shaft links to each other on fixing brake disc braking, so motor can be protected.Because use in the large-scale disintegrating apparatus open-pit mine mining environment, environment is abominable, wind speed is high, and the rotating part quality is big; Volume is big, and the hopper of unavoidable scratching disintegrating apparatus in the power shovel discharge process, and hopper and slew gear are no relative motions, and this scratching and wind carry and can produce very big impact to slew gear; And the impact that produces is born by reductor entirely, and the reductor speed ratio is big, through repeatedly impacting; Pinion to speed reducer output shaft can cause adverse effect, very easily wearing and tearing, even damage.This type of fault once appeared on the external disintegrating apparatus, and problem is difficult to solve.Therefore, develop that a kind of can to protect the rotary braking device of reductor in the slew gear be a new problem that needs to be resolved hurrily.
Summary of the invention
Deficiency to above-mentioned prior art; Technical problem to be solved by this invention provides a kind of rotary braking device of disintegrating apparatus; This rotary braking device can play a protective role to reductor and motor simultaneously; Also be easy to change after the friction member wearing and tearing of rotary braking device, and can be applied to the occasion of limited space system.
The objective of the invention is to realize like this: a kind of rotary braking device of disintegrating apparatus; By the directly moving brake of hydraulic pressure, brake disc, hydraulic pressure directly moving brake bearing, be used for fixing brake disc thread connector, be used for fixing hydraulic pressure directly the thread connector of moving brake form; Between pivoting support and steel construction that this pivoting support flange connects, brake disc is installed; Connect together pivoting support, the steel construction, the brake disc that connect with this pivoting support flange through thread connector, brake disc is circular ring, which is provided with the bolt hole a that connects pivoting support; Bearing is connected with the steel construction of brake disc rotation relatively; Bearing is formed by the steel plate welding, which is provided with to connect the hydraulic pressure directly screwed hole or the unthreaded hole of moving brake, is connected to the directly moving brake of hydraulic pressure on the bearing through thread connector; The operation principle of said device is; Brake disc and pivoting support in the rotary braking device link together; When the directly moving brake of hydraulic pressure is done the time spent; The hydraulic pressure directly friction surface up and down of moving brake contacts with the inward flange or the outward flange upper and lower surfaces of brake disc, and clamps to realize the braking of gyration; A kind of disintegrating apparatus that comprises according to any one said rotary braking device of aforementioned claim.
Main points of the present invention are its structure and operation principle.Its operation principle is; Brake disc and pivoting support in the rotary braking device link together; Do the time spent when the directly moving brake of hydraulic pressure, the hydraulic pressure directly friction surface up and down of moving brake contacts with the inward flange or the outward flange upper and lower surfaces of brake disc, and clamps to realize the braking of gyration.
A kind of rotary braking device of disintegrating apparatus compared with prior art; The rotary braking device is braked the pivoting support in the slewing equipment; Can play a protective role to reductor and motor simultaneously; Also be easy to change after the friction member wearing and tearing of rotary braking device, and can be applied to the occasion of limited space system, will be widely used in the portable crushing plant.
