Description
Technical field
The utility model relates to safety of pumping unit brake field, particularly relates to a kind of composite safe braking device, can make pumping unit on the basis of former braking device, meet linear quadratic braking.
Background technique
The braking device of existing oil-field oil pumper is by brake manual draw bar, linkage mechanism, hem type ring-shaped brake sheet and Brake drum composition.Manual pull-up brake manual draw bar, then by linkage mechanism, active force is acted on hem type ring-shaped brake sheet, hem type ring-shaped brake sheet holds Brake drum tightly, to reach brake object.But; this kind causes embrace the problems such as insufficient strength or frictional force weaken outward by linkage mechanism can be made because of each tie point under the long-time open-air atmosphere in the wild of braking device of mechanical linkage transmission to produce the reasons such as corrosion, stuck, wearing and tearing; and then affect the normal operation of linkage mechanism; even have a strong impact on oil pumping unit brake effect; if operator operate under the unstable outage state of steady brake; be very easy to cause the person and equipment injury once occur that original hem type ring-shaped brake lost efficacy, there is great potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of composite safe braking device, to eliminate because natural causes, environmental factor are on the impact of oil pumping unit brake braking device, realize pumping unit and carry out secondary composite braking on original outer basis of embracing winnowing machine, thus eliminate the harmful effect and potential safety hazard.
The technological scheme that the utility model adopts is: a kind of composite safe braking device, comprise brake bar, braking device, the brake hub that is connected with braking device, wire rope is connected with between brake bar and the brake lever of braking device, its special way is: this composite safe braking device is also provided with hydraulic hand-pump, in braking device corresponding left and right brake shoe in it relative upper-end surface between hydraulic pressure lateral thruster is set, between hydraulic hand-pump and hydraulic pressure lateral thruster, hydraulic oil pipe is set.
Further, described hydraulic pressure lateral thruster comprises piston cylinder, in piston cylinder, arranged on left and right sides arranges piston respectively, and the exterior edge face of described piston arranges piston jacking block, and described piston jacking block leans on the brake shoe interior edge face of correspondence.
The beneficial effects of the utility model are:
1, on original hem type ring-shaped brake basis, by hydraulic oil pipe, hydraulic hand-pump is connected with the hydraulic pressure lateral thruster be arranged in braking device again, hydraulic pressure lateral thruster acts on brake shoe and makes friction plate displacement, to extrude brake drum, act on the brake hub be installed on input shaft of reduction gearbox of oil pumping unit.Pumping unit is after cutting off the electricity supply; by original hem type ring-shaped brake speed reducing stopping; again by manually straining brake bar of the present utility model; brake rod acts on the friction plate of braking device by the active force of wire rope by brake bar, thus realizes the secondary safety brake under shutdown of pumping machine state.
2, hydraulic system and brake bar secondary composite braking is utilized; eliminate original hem type ring-shaped brake existing problems or suddenly external force misuse failure in the past; cause pumping unit gravity rotation under needs outage state suddenly; there is very large personal injury and device damage potential safety hazard; eliminate because natural causes, environmental factor are on the impact of oil pumping unit brake braking device; i.e. eliminate the harmful effect and potential safety hazard, and simple to operate, braking is reliable.
