The normally closed butt-clamp braking device comprises a brake disc, the brake disc is provided with at least one brake, each brake comprises two direct-acting brake units which are same and symmetrically clamped on the brake disc, each direct-acting brake unit comprises a hydraulic oil cylinder, a piston, an adjusting shaft, a disc spring and a proximity switch, and the adjusting shaft is provided with a friction plate; two direct-acting brake units are fixed on a connection adjusting plate through a high-strength bolt. According to the utility model, for overcoming the defects of complex structure, large installation space, easiness for wearing, long brake time, and the like in the prior art, a normally closed butt-clamp braking device which is small in volume, simple in structure, flexible in installation position and high in brake sensitivity is disclosed.
Description
Technical field
The utility model relate to a kind of be applicable to lifting, transportation, harbour, building machinery, wind-power electricity generation, hoist cable equipment and, the braking of big machinery or the break in deceleration field such as textile manufacturing machine, relate in particular to a kind of Normally closed type to folder braking device.
Background technique
Lifting braking, rotation and stop position in traditional lifting, transportation generally rely on operator's eyes to see behind position, take again braking, such setting is easy to miss optimal stopping position, if now braking in time, easily make main frame produce vibration, operation shakiness, lifting material easily swings, and produces unsafe factor; May have influence on the working life of complete machine simultaneously.At present, often adopt at home drum brake, drum brake is by lever working principle, step by step transferring power, hinge is many, and easy to wear, and adjustment cycle is short, complex structure, in braking process there is certain loss in strength, and the pusher rear brake period of braking of cutting off the electricity supply is long.
Conventional disk type braker in current braking automobile, period of braking is short, simple in structure, but because the required moment of braking of big machinery is large, disk type braker is not also applied at the brake field of main equipment.
Summary of the invention
The utility model overcomes the shortcomings such as large, the easy to wear and period of braking of the complex structure, the installing space that exist in above-mentioned prior art is long provides a kind of volume is little, simple in structure, mounting point is flexible and sensitivity is high Normally closed type to folder braking device.
The technical solution of the utility model is achieved in that a kind of Normally closed type is to folder braking device, comprise brake disc, at least one break is set on described brake disc, described break comprises two identical and symmetrical direct-acting type brake unit that are clipped on brake disc, described direct-acting type brake unit comprises hydraulic jack, the coupling shaft being connected with hydraulic jack, dish spring and approach switch, the signal plate of described approach switch is connected with described coupling shaft by adjusting bolt, on one end of described coupling shaft, friction plate is set, described dish spring is arranged on the external diameter of the described coupling shaft the other end, direct-acting type brake unit described in two is fixed on to connect by high-strength bolt and adjusts on plate.
On described hydraulic jack, be provided with the fixed plate of pressing friction sheet, described fixed plate is bolted on hydraulic jack.
On described each break, be provided with two approach switchs, be respectively and hold approach switch tightly and discharge approach switch.
On described brake disc, be provided with two breaks, described two breaks are symmetrical about disc centres.
The technique effect that the technical solution of the utility model produces is as follows: above-mentioned wafer type braking device volume is little, and installing space is little on main frame, and when the principle of employing disk type braker is braked, the response time is short; During according to braking, the difference of required moment can arrange one or more above-mentioned break on brake disc, meets the demand of different braking moment; And this apparatus structure is simple, use and maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model break.
Fig. 2 is the structural representation that dissects of the utility model break.
Fig. 3 is the structural representation of the utility model direct-acting type brake unit.
In figure, be labeled as: 1, brake disc; 2, hydraulic jack; 3, dish spring; 4, coupling shaft; 5, brake strip; 6, pressing plate; 7, pressing plate hold-down bolt; 8, screw; 9, connect and adjust plate; 10, approach switch; 11, grounding shell; 12, signal plate; 13, signal plate fixed block; 14, dust-proof cover; 15, adjusting bolt; 16, high-strength bolt.
Embodiment
A kind of Normally closed type is to folder braking device, as Fig. 1, 2, shown in 3, comprise brake disc 1, the break arranging on described brake disc, described break comprises two identical and symmetrical direct-acting type brake unit of clamping brake disc, described direct-acting type brake unit comprises hydraulic jack 2, coupling shaft 4, brake strip 5 together with being bolted with coupling shaft one end and be arranged on the dish spring 3 on coupling shaft the other end external diameter, on described hydraulic jack, connect a dust-proof cover 14, dish spring is arranged on dust-proof cover inside, on described dust-proof cover, be provided with approach switch 10, this approach switch transmits brake signal, described approach switch comprises grounding shell 11, signal plate 12, signal plate fixed block 13 and signal plate connecting bolt 15, this approach switch is electromagnetic type approach switch, the signal plate of approach switch is connected by adjusting bolt with coupling shaft, when direct-acting type brake unit discharges, signal plate approaches after grounding shell, switch connection.
This device also comprises a connection adjustment plate 9, described connection is adjusted on plate and is provided with 8 identical screws 8, on the hydraulic jack of two direct-acting type brake unit, be provided with 8 screws corresponding with connect adjusting screw on plate, two direct-acting type brake unit are connected to connect by 8 high-strength bolts 16 to be adjusted on plate.
This device also comprises the pressing plate 6 that compresses brake strip, and bolt hydraulic jack shell is connected by pressing plate hold-down bolt 7 with pressing plate, prevents friction brake wafer play when braking.
Under braking state, the hydraulic jack application of force, coupling shaft promotes brake strip and clamps brake disc (adjusting pressure according to required braking moment during installation), and main frame braking shuts down.When brake disc need to be worked, by external pumping plant, dish spring is compressed, both sides coupling shaft drives both sides brake strip and both sides high-strength bolt to two lateral movements, to realize braking release simultaneously, main frame rotation, approach switch spreads out of release signal.
In addition, two approach switchs can be set in above-described embodiment, an approach switch transmits brake signal, and another approach switch transmits release signal, can realize good effect of the present utility model equally.
In addition, in above-described embodiment, according to the difference of the required moment of braking, also two or more above-mentioned breaks can be set on brake disc, when break number being set being even numbers, break is symmetrical arranged about disc centres between two, increases braking moment, meets the demand of each scope braking moment.
