Abstract
The utility model provides a hydraulic block brake for hoisting machinery, which comprises a brake shoe, a brake arm, a draw rod and an angle lever that are orderly connected with the brake arm, a spring that is connected with the long arm of the angle lever and makes the brake shoe arranged on the brake arm be embraced tightly to the brake wheel; The utility model is characterized in that the long arm end of the angle lever is connected with a checking cylinder, a plunger controlled the checking cylinder and a manual pump (handle mode or pedal mode pump) having a connecting rod moving up and down or fore and after. When different brake moments are needed by the utility model, users only need to alter the propulsion impressed on the manual pump (handle pump or pedal pump), and different brake moments can be obtained. Compared with the existing technology, the utility model can be used in various occasions without alternating current power supply, and can adopts the manhandle and brake moment.
Description
Technical field
The utility model relates to a kind of break, particularly a kind of hydraulic pressure that is used for Hoisting Machinery (watt) block brake, can be used for using on the lifting equipment of on-electric.
Technical background
Be used at present that lifting equipment uses (watt) block brake (can be made into Normally closed type or structure open in usual), general electro hydraulicthruster or the electromagnetic type pusher of adopting, need to adopt Ac as power, when in the building site of AC-less power or during field work, to be subjected to the restriction of AC-less power condition and can't use (on the on-electric Hoisting Machinery, yet there are no the break that is suitable at present).In addition, the break of above-mentioned technology also exists braking force to be difficult for the shortcoming of adjusting.
The model utility content
The purpose of this utility model provides a kind of hydraulic pressure block brake that is used for Hoisting Machinery, uses this break can not need ac power supply, only needs to adopt manpower to brake, and braking moment can be controlled, and it is convenient and easy to handle control.
The utility model is realized with following technological scheme, this break still comprises braking tile fragment and the brake arm thereof that can be used for holding tightly (compressing) hoist Brake drum, the pull bar that is connected successively with brake arm, angle lever and one and angle lever long-armed is connected and allows the braking tile fragment produces the spring (available pressure spring or draught spring) that the trend of holding tightly is used to Brake drum on the brake arm, it is characterized in that: the manual pumps (for manually operated type or foot-operated pump) of (or front and back) action about the long arm end of angle lever is connected with a master cylinder (as being oil cylinder) and may command master cylinder piston and connecting rod thereof.
Working principle of the present utility model: when master cylinder is not worked, the active force of spring will be braked tile fragment and be pressed on the Brake drum by angle lever, pull bar, brake arm successively, produce braking moment.When needs were opened break, applied thrust on manual pumps produced oil pressure in the pipeline, promoted piston motion in the master cylinder, and angle lever is pushed open, and braking tile fragment and Brake drum break away from, and braking is removed.When needs different braking moment, only need to change the thrust that is applied on the manual pumps (hand pump or foot pump) and just can obtain different braking moments.Compared with the prior art, the utility model can use in the open-air various occasions of AC-less power, can adopt manpower to promote, and braking moment can be controlled flexibly, and handiness is reliable, uses oil pipe to connect flexible arrangement.
Description of drawings
Fig. 1 is a kind of overall structure schematic representation of the present utility model.
Wherein: 1～Brake drum (being fixedly connected) with the pto of Hoisting Machinery, 2～braking tile fragment, 3～brake arm, 4～pull bar, 5～angle lever, 6～(pulling force or pressure) springs, 7～braking (oil) cylinder, 8～oil pipe, 9～manual pumps (can be manually operated type pump or foot-operated pump), 10～Lever type handle (or using foot treadle), 11～outside control mouth (Decompression valves can be housed).
Embodiment
With reference to accompanying drawing as can be known, the utility model also has following technical characteristics when specific design:
One, described manual pumps 9 can be a kind of manually operated type pump, and the piston rod of this manually operated type pump has connected a Lever type handle 10.
Two, described manual pumps 9 can also be a kind of foot-operated pump, and the piston rod of this foot-operated pump also can connect a Lever type foot treadle (accompanying drawing slightly).
Three, (or on master cylinder or manual pumps) adds an outside control mouth 11 on oil pipe pipeline of the present utility model; draining outlet during as safety protection; its working principle: as the external control signal; as overload or height limiter when sending signal; the Decompression valves of outside control mouth is opened automatically, and pressure oil discharges from outside control mouth.
Claims (3)
