Abstract
The utility model relates to the technical field of a brake, in particular to a building block type safety brake. The building block type safety brake comprises a supporting seat and a support frame; the supporting seat is provided with a brake disc; the support frame is provided with a brake component for controlling the brake disc; the brake component is provided with a disc type self-locking device; the brake component comprises a sliding seat, a building block, an electromagnetic valve and a friction plate; the sliding seat is symmetrically distributed at two lateral surfaces of the brake disc; the building block is mounted on the sliding seat in sliding manner; the electromagnetic valve is located at the bottom of the building block for controlling the running of the building block; the friction plate is located between the brake disc and the building block. The building block type safety brake is suitable for reel devices on engineering machinery, hoisting machinery, mine machinery, a winch, a hoist and so on. The building block type safety brake is mounted at each of the left and right sides of the reel device, when the service brake of the reel device is out of order, the building block type safety brake can enter working state instantaneously, and accordingly a cable which is wound on the reel, a hook on the cable and workpieces are effectively avoided from the free-fall motion caused by the weight thereof.
Description
Technical field
The utility model relates to the technical field of drg, especially a kind of building-brick type sure brake.
Background technology
The main equipments such as construction machinery and equipment, elevator machinery, mining machinery, winch and headstock gear have very important status in industry-by-industry, roll device is one of their vitals, for the sake of security, on roll device, can be equipped with service brake, but the malfunctioning phenomenon of the normal appearance of existing service brake, the suspension hook and the workpiece that are wound in like this on hawser, the hawser on reel are done the movement of falling object because of own wt, easily cause safety misadventure.
Service brake is originally the need moment of torsion that guarantees drg by the pressure of spring, and the size of spring pressure determines the size of moment of torsion, and it is that drg is not worked by hydraulic power unit and oil cylinder Compress Spring that drg is thrown off.Power-off drg under action of the spring is started working.The shortcoming of spring loaded service brake is to damage when spring failure, and oil cylinder, hydraulic power unit, hydraulic oil change along with the variation of weather and temperature, all likely cause service brake malfunctioning.
And safety drg adopts full mechanical drive principle, not outer dynamic braking moment of torsion, but by this mechanism angle, self-weight self-locking braking work, working motion is to produce the movement of falling object by own wt, sure brake is de-makes building block upward movement and disengagement work by electromagnetic valve effect.Drg brake torque increases along with the increase of workpiece moment of torsion, and brake torque is directly proportional to operation torque, and single brake torque is far longer than the moment of torsion of spring loaded service brake, and therefore this drg brake torque is large, more safe and reliable.
Utility model content
The technical problems to be solved in the utility model is: the utility model provides a kind of building-brick type sure brake; it is for being arranged on the left and right sides of roll device; when the service brake on roll device is malfunctioning; building-brick type sure brake of the present utility model will enter mode of operation moment; suspension hook and the workpiece avoiding being wound on hawser, the hawser on reel are done the movement of falling object because of own wt, have played good safety guard-safeguard effect.
The utility model solves the technical scheme that its technical matters adopts: a kind of building-brick type sure brake, be applicable to construction machinery and equipment, elevator machinery, mining machinery, roll device on winch and headstock gear etc., be installed on the left and right sides of roll device, there is supporting seat and bracing frame, brake disc is installed on supporting seat, brake assemblies for controlling brake disc is installed on bracing frame, disc type self-locking device is installed on brake assemblies, brake assemblies comprises the slide that is symmetrically distributed in brake disc two sides, be slidably mounted on the building block on slide, in building block bottom and be used for controlling the electromagnetic valve of building block operation and the friction lining between brake disc and building block.
Further limit: between friction lining and building block, being angle is 1 °～50 °.
The beneficial effects of the utility model: building-brick type sure brake of the present utility model is specially adapted to construction machinery and equipment, elevator machinery, mining machinery, roll device on winch and headstock gear etc., it is installed on the left and right sides of roll device, work as construction machinery and equipment, elevator machinery, mining machinery, when service brake on winch and headstock gear etc. is malfunctioning, this building-brick type sure brake can enter mode of operation moment, effectively prevent from being wound in the hawser on reel, suspension hook on hawser and workpiece are done the movement of falling object because of own wt, played good safety guard-safeguard effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model building-brick type sure brake;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is that building-brick type sure brake of the present utility model is for the structural representation on headstock gear.
In figure: 1, supporting seat, 2, bracing frame, 3, brake disc, 4, brake assemblies, 41, slide, 42, building block, 43, electromagnetic valve, 44, friction lining, 5, disc type self-locking device, 6, service brake, 7, roll device, 8, hawser, 9, suspension hook.
The specific embodiment
Building-brick type sure brake as shown in Figure 1, be applicable to the roll device 6 on construction machinery and equipment, elevator machinery, mining machinery, winch and headstock gear etc., be installed on the both sides of roll device 6, this building-brick type sure brake has supporting seat 1 and bracing frame 2, brake disc 3 is installed on supporting seat 1, the brake assemblies 4 for controlling brake disc 3 is installed on bracing frame 2.
As shown in Figure 2, disc type self-locking device 5 is installed on brake assemblies 4, brake assemblies 4 comprise be symmetrically distributed in brake disc 3 two sides slide 41, be slidably mounted on building block 42 on slide 41, in building block 42 bottoms and be used for controlling electromagnetic valve 43 that building block 42 moves and the friction lining 44 between brake disc 3 and building block 42.Wherein between friction lining 44 and building block 42, being angle is 1 °～50 °.
Principle of work: when after electromagnetic valve 43 power-off in brake assemblies 4, the movement of falling object is done in building block 42 downwards, and building block 42 arrives behind certain position, friction lining 44 and brake disc 3 will auto locks, keep building block 42 positions to fix; When after the energising of building-brick type sure brake, disc type self-locking device 5 makes building block 42 upward movements under the effect of electromagnetic valve 43, building block 42 and brake disc 3 is come off out, i.e. not work volume cartridge 7 normal operations of drg.
As shown in Figure 3; this building-brick type sure brake is for headstock gear; when the service brake 6 on headstock gear is malfunctioning; the building-brick type sure brake that is installed on roll device 7 two ends, left and right will enter mode of operation moment; suspension hook 9 and the workpiece that can effectively prevent from being wound on hawser 8, the hawser 8 on roll device 7 are done the movement of falling object because of own wt, have played good safety guard-safeguard effect.
