Description
Technical field
The utility model relates to a kind of brake equipment, and particularly a kind of brake equipment for winch, belongs to mechanical field.
Background technology
Winch, with the small-sized weight-lifting equipment of reel lay winding wire ropes or chain lifting or traction weight, also known as winch.Winch vertical-lift, level or inclination can be dragged and draw weight.By brake equipment, winch is braked in the working process of winch.The brake equipment of winch traditional at present adopts the mode of mechanical braking to brake winch mostly, the brake equipment of this structure adopts brake wheel or brake drum to brake mostly, lock torque required during this arrangement works is longer, brake contact surface compared with little, poor sensitivity, braking effect is poor, complex structure, volume are large, serious wear after long-time use, is unfavorable for that the use of winch is with universal.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and the utility model provides that a kind of contact surface that brakes is larger, highly sensitive, simple and reasonable for structure, the brake equipment of the winch of long service life.
The utility model solves the technical scheme that its technical matters adopts: a kind of brake equipment of winch, comprise braking supporting disk, described braking supporting disk is provided with bolt, described bolt one end end winding support has the first disk, described bolt slidably connects second disk between the first disk and braking supporting disk, coil is provided with between described first disk and second disk, described bolt is provided with retarding spring between the first disk and second disk, some brake facings are provided with between described second disk and braking supporting disk, described bolt slidably connects steel friction plate between every adjacent two panels brake facing.
As preferably, described bolt is equipped with nut in the both sides of the first disk, and described first disk is fixed on bolt by nut.
As preferably, described bolt is also provided with stop-off nut between the first disk and second disk, and one end and the stop-off nut of described retarding spring abut against, and the other end and second disk abut against.
As preferably, described brake facing is two panels.
Adopt in the utility model second disk, retarding spring, steel friction plate and brake facing and braking supporting disk be compacted into normally closed mode to brake, the brake contact surface of the brake mode of this structure is large, and good braking effect; The utility model arranges coil and retarding spring to control the open and-shut mode between second disk and brake facing between the first disk and second disk, behind coil electricity source, spacing between first disk and second disk closes, make brake facing play brake action, this arrangement enhance brake equipment sensitivity in use; Nut of the present utility model and stop-off nut are all adjustable on bolt, change the thrust of brake equipment when braking and stopping distance by setting nut and stop-off nut; The utility model also has the advantages such as simple and reasonable for structure, long service life.

Fig. 1 is the integral structure schematic diagram of the utility model embodiment.
In figure: 1, brake supporting disk, 2, bolt, the 3, first disk, 4, nut, 5, second disk, 6, coil, 7, stop-off nut, 8, retarding spring, 9, brake facing, 10, steel friction plate.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
The brake equipment of a kind of winch as shown in Figure 1, comprises braking supporting disk 1, and braking supporting disk 1 is provided with bolt 2; End, described bolt 2 one end is provided with the first disk 3, and bolt 2 is equipped with nut 4 in the both sides of the first disk 3, and the first disk 3 is fixed on bolt 2 by nut 4; Described bolt 2 slidably connects second disk 5 between the first disk 3 and braking supporting disk 1, coil 6 is provided with between first disk 3 and second disk 5, bolt 2 is provided with retarding spring 8 between the first disk 3 and second disk 5, bolt 2 is also provided with stop-off nut 7 between the first disk 3 and second disk 5, one end and the stop-off nut 7 of described retarding spring 8 abut against, and the other end and second disk 5 abut against.; Be provided with two panels brake facing 9 between described second disk 5 and braking supporting disk 1, bolt 2 slidably connects steel friction plate 10 between two panels brake facing 9.
In use, brake facing 9 is fixedly connected with the rotating shaft of winch, and when power supply is in off-state, brake facing 9 compresses by second disk 5 under the effect of retarding spring 8, and brake equipment is in locking state; When after power supply energising, produce electromagnetic induction between coil 6 and the first disk 3, second disk 5, second disk 5 adsorbs by the first disk 3, and the thrust of second disk 5 pairs of brake facings 9 disappears, and brake equipment is in open mode.
Adopt in the utility model second disk 5, retarding spring 8, steel friction plate 10 and brake facing 9 and braking supporting disk 1 be compacted into normally closed mode to brake, the brake contact surface of the brake mode of this structure is large, and good braking effect; The utility model arranges coil 6 and retarding spring 8 to control the open and-shut mode between second disk 5 and brake facing 9 between the first disk 3 and second disk 5, after coil 6 energize, spacing between first disk 3 and second disk 5 closes, make brake facing 9 play brake action, this arrangement enhance brake equipment sensitivity in use; Nut of the present utility model 4 is all adjustable on bolt 2 with stop-off nut 7, changes the thrust of brake equipment when braking and stopping distance by setting nut 4 and stop-off nut 7; The utility model also has the advantages such as simple and reasonable for structure, long service life.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
