Abstract
The utility model provides a safety braking device used for wheel-side braking. The safety braking device comprises a pincer-like base and an electro-hydraulic propeller. An installation bottom plate is arranged on the pincer-like base through a fixed base. The bottom of the body of the electro-hydraulic propeller is hinged to one end of the top of the installation bottom plate. A piston rod of the electro-hydraulic propeller is hinged to one end of a transmission connecting rod. The other end of the transmission connecting rod is hinged to the top of an upper lock threaded rod. The bottom of the upper lock threaded rod is meshed with the upper end of a lock nut. The lower end of the lock nut is meshed with a lower lock threaded rod on the installation bottom plate. The upper end of a braking connecting rod is hinged to the middle of the transmission connecting rod, and the lower end of the braking connecting rod is connected with inclined blocks in the pincer-like base after penetrating through the installation bottom plate. An upper friction plate is arranged at the bottom of each inclined block. The upper friction plates are used in cooperation with a lower friction plate on the pincer-like base for conducting braking on a brake disc. The safety braking device is simple in structure, high in reliability and good in braking effect.
Description
Technical field
The utility model relates to the large torque wheel of slow-speed of revolution brake field, refers in particular to a kind of for taking turns the safety catch of limit braking.
Background technique
At present, be applied to the safety brake of the large torque wheel of the slow-speed of revolution, generally adopt hydraulic brake, need special hydraulic station to support the use; But hydraulic system itself exists, power loss is large, efficiency is low, heating is large; While adopting oil as driving medium, also should be noted that fire safety problem; Hydraulic element requirement on machining accuracy is high, and cost is high; Hydraulic system fault is more difficult to be searched, and requires high to operator's technical merit.Hydraulic element device easily produces leakage, causes system pressure to decline, and cannot produce effective braking.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, reliability is high, the safety catch of good braking effect.
For achieving the above object, technological scheme provided by the utility model is: a kind of for taking turns the safety catch of limit braking, it includes pincerlike seat, skewback, mounting base, electricity liquid propulsion device, wherein, mounting base is arranged on pincerlike seat by fixed base, electricity liquid propulsion device bottom part body is hinged on one end, mounting base top, electricity liquid locomotive piston bar and kinematic link one end are hinged, the kinematic link the other end is hinged on lock screw rod top, above lock screw rod bottom is engaged on split nut upper end, to split nut lower end with on mounting base lower to lock screw rod be meshed, brake connecting rod upper end is hinged on kinematic link middle part, and lower end is through being connected with the skewback in pincerlike seat after mounting base, skewback bottom is provided with upper friction plate, and upper friction plate matches brake disc is braked with the lower friction plate on pincerlike seat.
Described mounting base bottom is provided with the limiting stopper matching with skewback.
The utility model is adopting after such scheme, drive kinematic link to rise when protruding upward under the instruction of electric liquid propulsion device in control system, kinematic link drives brake connecting rod that skewback is moved up, thereby makes upper and lower friction plate depart from brake disc, and braking moment is eliminated; In the time resetting under the instruction of electric liquid propulsion device in control system, kinematic link drives brake connecting rod that skewback is declined, upper friction plate is fitted on brake disc, skewback is under the effect of frictional force, left/right movements, the inclined-plane that utilizes shape seat self is produced to self-servo action, and produce required braking moment.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1, safety catch described in the present embodiment, it is characterized in that: it includes pincerlike seat 1, skewback 2, mounting base 5, electricity liquid propulsion device 14, wherein, mounting base 5 is arranged on pincerlike seat 1 by fixed base 6, electricity liquid propulsion device 14 bottom part body are hinged on mounting base 5 one end, top, electricity liquid propulsion device 14 piston rods and kinematic link 16 one end are hinged, kinematic link 16 the other ends are hinged on lock screw rod 28 tops, above lock screw rod 28 bottoms are engaged on split nut 27 upper ends, to split nut 27 lower ends with on mounting base 5 lower to lock screw rod 26 be meshed, brake connecting rod 7 upper ends are hinged on kinematic link 16 middle parts, and the skewback 2 after mounting base 5 is passed in lower end and in pincerlike seat 1 is connected, skewback 2 bottoms are provided with upper friction plate 4, and upper friction plate 4 matches brake disc is braked with the lower friction plate 3 on pincerlike seat 1, mounting base 5 bottoms are provided with the limiting stopper 23 matching with skewback 2.Drive kinematic link to rise when protruding upward under the instruction of electric liquid propulsion device in control system, kinematic link drives brake connecting rod that skewback is moved up, thereby makes upper and lower friction plate depart from brake disc, and braking moment is eliminated; In the time resetting under the instruction of electric liquid propulsion device in control system, kinematic link drives brake connecting rod that skewback is declined, upper friction plate is fitted on brake disc, skewback is under the effect of frictional force, left/right movements, the inclined-plane that utilizes shape seat self is produced to self-servo action, and produce required braking moment.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
