Abstract
The utility model relates to a brake for the translational mechanism of a crane. The utility model is characterized in that a middle part which is arranged on a long braking arm is hinged with the top end of the long braking arm; a manual braking lever with unequal arms is arranged on the long braking arm, and one end of the manual braking lever is hinged with a push rod connecting plate. Because the utility model is provided with a manual braking mechanism, braking and stopping of a car can be realized by a crane under the condition of power failures or the damaged elements of an electrical apparatus, so that driving safety can be guaranteed, and the occurrences of accidents can be avoided.
Description
The utility model relates to a kind of hoisting crane translation mechanism drg, but mainly all is hinged with the arc brake scotch of obvolvent brake wheel by the centre, two ends respectively with support and two not isometric brake control levers of pull bar pivotally attached; Two-end-point is sagging, and the portion of arching upward is hinged on the chevron pointing multiplying lever of long brake control lever; One end footpath main spring frame and chevron pointing lever short arm are hinged, and the other end and short brake control lever top pivotally attached pull bar are formed.Cut with scissors mutually with the long arm end of chevron pointing lever on the push rod top of pusher.Belong to braking technology.
Shortcomings such as present various crane all uses normally closed brake, and drg is opened a sluice gate simultaneously when cart starts, and drg is braked at once when cart stops, and the function that does not have elder generation to slow down and afterwards brake causes the position or too quickly of stopping, and is wayward.Present most hoisting crane is vehicle brake greatly all, slows down and stops and reach with the mode of driving in reverse gear, and does the purpose that can reach accurate stopping like this.But weak point is that tripping operation suddenly has a power failure in the cart high-speed cruising process, perhaps because of electric elements damage, can cause the disease of covering that cart can not effectively control, and grave accidents such as personal injury and damage equipment can take place brake failure.
The purpose of this utility model provides that a kind of operating effort is very little, deceleration arbitrarily, accurate stopping, also can in time control the hoisting crane hoisting crane translation mechanism drg of parking in time when having a power failure or damaging because of electric elements.
The purpose of this utility model is to realize by following technical measures: hoisting crane translation mechanism drg provided by the utility model, form by brake bracket open in usual and MYTZ dust protected electro hydraulicthruster and hand brake mechanism, it is hinged that a pars intermedia and its top are set on long brake control lever, an end and push rod lengthening end pivotally attached unequal arm hand brake lever.
When driving, in case power failure or electric elements are malfunctioning, promptly available hand is moved the vacant termination of hand brake lever, reaches the purpose of braking.
Under general situation, the vacant termination of hand brake lever is often away from control cabin, therefore can be at the manual vacant termination tying wire rope of system lever, and available the way that pulley changes the trend of steel rope is set, steel rope is introduced in the control cabin.So just can in control cabin, be provided with steel rope bonded assembly handle to come hoisting crane is carried out brake operating.
Because the utility model is provided with hand brake mechanism, therefore under the situation of power failure or electric elements damage, can make the hoisting crane stopping-down, thereby guarantee the safety of driving, avoid the generation of accident.
Accompanying drawing is a structural representation of the present utility model, and wherein Fig. 1 is the straight arm type drg, and Fig. 2 is a curved boom formula drg.
Be further described below in conjunction with the technical characterictic of accompanying drawing most preferred embodiment of the present utility model.
A kind of mainly hinged with support (12) respectively by lower end, but pars intermedia is provided with the short brake control lever (10) and long brake control lever (4) of the arc axis tile (9) of obvolvent brake wheel (11), be arranged on the hydraulic driver that has coupling plate (3) (1) of long brake control lever one side, pars intermedia and long brake control lever are hinged, and both ends are respectively with push rod and and be hinged on the hoisting crane drg that chevron pointing multiplying lever (2) that the pull bar that has spring frame (8) on the short brake control lever is hinged is formed.
It is hinged that a pars intermedia and its top are set on long brake control lever, an end and push rod coupling plate pivotally attached unequal arm hand brake lever (5).
In the present embodiment, the way of employing tying wire on the vacant end of hand brake lever reaches the purpose in the braking of control cabin inner control, and be to have on the hand brake lever end arm of steel rope to offer through hole (6), inserting on the through hole and can borrow himself weight make push rod upwards be raised up to the counterweight (7) on summit under normal conditions.The arm end that will have a weight by steel rope before braking is mentioned, and discharges brake wheel.When using electrodynamic braking, when promptly push rod rises, can not influence the whereabouts of weight arm end.
Claims (2)
1, a kind of mainly hinged with support (12) respectively by lower end, but pars intermedia is provided with the short brake control lever (10) and long brake control lever (4) of the arc axis tile (9) of obvolvent brake wheel (11), be arranged on the hydraulic driver (1) that has lengthening push rod (3) of long brake control lever one side, pars intermedia is hinged with long brake control lever, both ends respectively with push rod and be hinged on the hoisting crane drg that chevron pointing multiplying lever (2) that the pull bar that has spring frame (8) on the short brake control lever is hinged is formed, it is characterized in that a pars intermedia is set on long brake control lever and its top hinged, an end and push rod coupling plate pivotally attached unequal arm hand brake lever (5).
2, hoisting crane translation mechanism drg according to claim 1, it is characterized in that being to have on the hand brake lever end arm of steel rope to offer through hole (6), insert on the through hole and can borrow himself weight make coupling plate and push rod upwards be raised up to the counterweight (7) on summit under normal conditions.
