Detailed description of the invention
The enforcement of brake is such as shown in Fig. 1 ~ Fig. 2, a kind of power hydraulic pressure drum brake, including brake mount 1, brake mount 1 is provided with bourdon tube 2, spring pull bar 3 it is provided with in bourdon tube 2, the external part that spring pull bar 3 stretches out bourdon tube 2 is connected with the joint (not shown) being located between brake arm activation lever 4, being additionally provided with in brake mount 1 and be positioned at the pusher 6 declutched for the realization when energising on the right side of bourdon tube 2, power hydraulic pressure drum brake also includes for the brake arm 7 of braking brake, brake block 8 and friction facing 9.It is provided with hand release 5 between upper end and the joint of bourdon tube 2, hand release 5 includes base 51, base 51 offers the fixing hole 52 for hand release 5 is fixed on bourdon tube 2 upper end, base 51 is provided with screw-nut mechanism, screw-nut mechanism includes leading screw 57 and screw 58, leading screw 57 is torque input end, screw 58 is the linearly operating outfan driving brake arm activation lever 4 action, and hand release 5 also includes the moment of torsion input structure to leading screw 57 input torque.Moment of torsion input structure includes the output bevel gear wheel 56 coaxially fixed with leading screw 57 and takes turns the input bevel gear of 56 engaged transmission with output bevel gear, base 51 is provided with the thrust ball bearing 59 supporting output bevel gear wheel 56 and leading screw 57, base 51 upper end is installed with shell 53 by screw 54, output bevel gear wheel 56 and thrust ball bearing 59 may be contained within described shell 53, shell 53 upper end offers the vertical vertical core passed through for screw 58, the gear shaft 55 of input bevel gear stretches out described shell 53 through the sidewall of shell 53 towards right side, gear shaft 55 stretches out the external part of shell 53 and is provided with mean for the joint portion that spanner inserting rotates, shell 53 is provided with end cap 50, leading screw 57 and screw 58 and base 51 offer the pull bar perforation run through for spring pull bar 3.
The operation principle of this brake is: when energising in mechanism, the push rod of pusher 6 rises rapidly, by the effect of brake arm activation lever 4, the brake block 8 being connected on brake arm 7 is opened, so that friction facing 9 separates with braking dish, realization is declutched, in this process, along with the rise of pusher 6 push rod, spring pull bar 3 is stretched out bourdon tube 2 under the effect of brake arm activation lever 4 and joint.When power-off in mechanism, under spring force, spring pull bar 3 is retracted in bourdon tube 2, and the push rod of pusher 6 declines rapidly, and by the effect of brake arm activation lever 4, brake block 8 is closed up, and makes friction facing 9 and brake disc, it is achieved band-type brake.When in use, due to have a power failure stop in emergency or current check maintenance time, when needing manual unlocking brake, utilize the joint portion of spanner rotary teeth wheel shaft 55, by the rotation rotarily driving output bevel gear wheel 56 of gear shaft 55, so that leading screw 57 rotates, rotation along with leading screw 57, screwed out with the screw 58 of leading screw 57 screw-driven, thus jack-up brake arm activation lever 4 moves up, realize manually declutching under the effect of brake arm activation lever 4.
When not needing manual unlocking brake, whole hand release is fixed between bourdon tube upper end and joint, is not take up additional space so that the overall structure of brake is compact.The external diameter of the output bevel gear wheel in hand release is more than the external diameter of input bevel gear, so by rotating input bevel gear, it is obtained with a bigger output moment of torsion, so that hand release is more laborsaving, avoid when prior art utilizes rotation release spanner relatively elaborate, or even the problem that manpower cannot discharge.
In other embodiments of brake: hand release is also applied for electric hydraulic arm disc brake；Hand release can also be arranged in brake mount, as long as its linearly operating outfan contacts with brake arm activation lever and can by brake arm activation lever jack-up；Moment of torsion input structure may not be the gear pair of pair of meshing transmission, it is possible to is the structure being set directly on torque input end for input torque；The gear shaft of hand release is not necessarily towards right side, according to applying working condition requirement, it is possible to is adjusted by hand release and is fixed on bourdon tube to suitable position again.
The enforcement of hand release is such as shown in Fig. 1 ~ Fig. 2, and the concrete structure of hand release is identical with the hand release in above-mentioned brake, is not described in detail in this.
