Description
Technical field
The utility model is related to a kind of energy-saving roller brake apparatus, belong to art of braking devices.
Background technology
Preceding common braking system has mechanical brake shoe to brake, electric driving force braking, hydraulic braking and hydraulic braking etc..Electrically
Braking ability is relatively stablized, but braking system can not just work in unexpected power-off；Hydraulic braking not only system complex, and turning
Braking moment is reduced rapidly in the case of speed is lower, is still needed to mechanical brake shoe and is carried out dry friction braking；And mechanical brake shoe is braked,
Since it will produce spark and burn phenomenon, harm is generated to production safety, thus the use of hydraulic braking just seems increasingly
Urgently.With long range, the extensive use of large conveying quantity, powerful ribbon conveyer, perfect, the performance of brake apparatus function
Quality, directly affect the safety and reliability service of ribbon conveyer.Patent CN201120317355.5 discloses a kind of liquid
Pressing tongs disk brake, can be used for belt conveyor's pulley braking, belongs to normally closed brake, be in braking shape when power is off
State has the advantages that safe and reliable.It when conveyer is powered on needs that hydraulic system is kept persistently to provide pressure to hydraulic cylinder
Power is at disengaging braking, therefore needs to consume larger electric energy in conveyer working condition hydraulic system.
Invention content
The purpose of this utility model is to provide a kind of energy-saving roller brake apparatus, concrete scheme is：
A kind of energy-saving roller brake apparatus, including pedestal and two opposite tong arms being articulated on pedestal, two pincers
The tail portion of arm is connected by hydraulic mechanism, head be equipped with opposite brake block, the hydraulic mechanism include cylinder body and be set to cylinder body
Interior piston, the upper end of cylinder body are connect with one of tong arm, and the piston is connected with pull rod, and pull rod connects with another tong arm
It connects, pull rod is equipped with butterfly compression spring, and the cylinder body is equipped with main oil inlet along the lower section of piston；The upper inside wall of the cylinder body is equipped with ring
The opening of shape slot, annular groove is fixed with elastic rubber interlayer, and the height of elastic rubber interlayer is no more than inboard wall of cylinder block surface；Institute
It states annular groove and is equipped with secondary oil inlet.
Further, the width of the annular groove is no more than the width of piston.
Further, the depth of the annular groove is no more than the 1/4 of cylinder side wall thickness.
The beneficial point of the utility model is：This programme is improved on the basis of existing fluid pressure type clipper disk brake,
The annular groove being connected to hydraulic system is set in the upper end of hydraulic cylinder, and annular groove opening is arranged elastic rubber interlayer, is conveying
When machine is powered on, piston moves up, and brake is detached from braking, while hydraulic oil is injected in annular groove, passes through elastic rubber interlayer
Radial pressure is generated to piston, under the effect of this pressure, the contact surface of elastic rubber interlayer and piston can be made to generate larger rub
Wipe resistance.With this condition, hydraulic system, which provides smaller pressure, can make the state that brake apparatus remains disengaged from braking, to
Reach energy-efficient effect.

Fig. 2 is the structural schematic diagram of hydraulic mechanism in the utility model.
Specific implementation mode
Embodiment 1
A kind of energy-saving roller brake apparatus as shown in Figure 1, 2, including pedestal and be articulated on pedestal two it is opposite
Tong arm 2, the tail portion of two tong arms 2 connected by hydraulic mechanism 3, and head is equipped with opposite brake block 1, the hydraulic mechanism 3
Piston 302 including cylinder body 301 and in cylinder body 301, the upper end of cylinder body 301 are connect with one of tong arm, the piston
302 are connected with pull rod 304, and pull rod 304 is connect with another tong arm, and pull rod is equipped with butterfly compression spring 303, and butterfly compression spring is for providing
The power that hydraulic mechanism resets, the cylinder body 301 are equipped with main oil inlet 5 along the lower section of piston 302；The top of the cylinder body 301
Inner wall is equipped with annular groove 6, and the opening of annular groove 6 is fixed with elastic rubber interlayer 7, and the height of elastic rubber interlayer 7 is no more than
Inboard wall of cylinder block surface；The annular groove 6 is equipped with secondary oil inlet 4.Main oil inlet 5 and secondary oil inlet 4 are used to connect with hydraulic system
It connects.The position of annular groove 6 is corresponding with the stroke upper limit of piston 302, and the width of annular groove 6 is no more than the width of piston 302.It examines
There is influence in the setting for considering annular groove, the depth of the annular groove is no more than the 1/4 of cylinder side wall thickness, separately on cylinder strength
Outside, the wall thickness of cylinder body can also be redesigned or outer wall of cylinder block is along the position of annular groove setting reinforcing section.
The good fluorubber of wearability can be used in elastic rubber interlayer 7, and stepped groove, fluorubber is arranged in the opening of annular groove
It is adhesively fixed in stepped groove by vulcanization.
This programme is improved on the basis of existing fluid pressure type clipper disk brake, setting and hydraulic pressure in the upper end of hydraulic cylinder
Elastic rubber interlayer is arranged in the annular groove of system connectivity, annular groove opening, and when conveyer is powered on, piston moves up, system
Dynamic device is detached from braking, while hydraulic oil is injected in annular groove, generates radial pressure to piston by elastic rubber interlayer, presses herein
Under force effect, the contact surface of elastic rubber interlayer and piston can be made to generate larger frictional resistance.With this condition, hydraulic system
The state that brake apparatus remains disengaged from braking can be made by providing smaller pressure, to reach energy-efficient effect.
