Abstract
The utility model relates to an oil pumping unit brake locking device, comprising an adjusting pull rod connected with a brake hoop in a penetrating mode, wherein, the adjusting pull rod is sheathed with a reset spring, a fixed bearing and a U-shaped baffle plate. The adjusting pull rod on the inner side position of the baffle plate is provided with a locknut for locking the brake hoop, and one end of the adjusting pull rod extending out of the U-shaped baffle plate is provided with a connecting hole assembled with a brake control connecting rod. The device can effectively prevent an oil pumping unit from improperly rotating to cause mechanical or personal accidents and can thoroughly solve the security risk problem of oil pumping unit sliding caused by a variety of causes. The device has the advantages of simple structure, convenient operation, safety, reliability, etc.
Description
Technical field
The utility model belongs to oil pumper brake technical field, specifically is a kind of oil pumper brake locking device.
Background technology
The most hem types that adopt of the brake of each oil field beam pumping unit at present; all be with its shutdown laggard line operate of tight brake of stopping when oil pumper needs maintenance, adjustment, replacing and oil well operation, its brake locking is that the click by brake lever in the manipulation device cooperates and realizes fully.Because the brake reliable lock is poor, under braking state, safeguard, can occur during workover treatment phenomenons such as brake failure, mistake get off the brakes, error starting oil pumper, cause the slide car that oil pumper is rotated easily and cause machinery, personal injury, therefore, in the apply the brakes process, there is certain security risk.
The utility model content
The purpose of this utility model is to provide a kind of can prevent effectively that oil pumper brake failure, mistake from getting off the brakes, error starting, guarantees the oil pumper brake locking device of oil pumper safety in production.
Realize that the technical scheme that above-mentioned purpose is taked is: this device has one and binds round with brake and to install the adjusting yoke that is connected, be set with back-moving spring, fixed bearing and U type baffle plate on it, the locking nut that is used to lock the brake hoop is housed on the adjusting yoke of baffle plate inside line, and adjusting yoke stretches out the connecting hole that an end is provided with and the control link that brakes is assembled of U type baffle plate.
Described pull bar adopts full thread shaft-like.
The oil pumper brake locking device of making according to such scheme, during use brake stop tight after, with the fastening locking nut of spanner, can effectively lock brake, thereby avoid the improper rotation of oil pumper to cause machinery or personal injury, thoroughly solve oil pumper that a variety of causes causes and slip the potential safety hazard of car, and, advantages such as this device has simple in structure, and is easy to operate, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, oil pumper brake locking device of the present utility model, form by adjusting yoke 1, back-moving spring 2, fixed bearing 3, U type baffle plate 4 and locking nut 5, wherein, adjusting yoke 1 is connected with brake hoop 7 in the oil pumper braking mechanism, back-moving spring 2 and fixed bearing 3 are installed on the adjusting yoke 1, and fixed bearing 3 is fixedly connected on the oil pumping unit reduction gearbox, are used for fixing the relative position between adjusting yoke 1 and brake hoop 7 and the brake wheel.U type baffle plate 4 is installed on the adjusting yoke 1 end that is connected with the brake control link, and binds round 7 the outside with brake and contact, and locking nut 5 is positioned at the inboard of U type baffle plate 4, and with adjusting yoke 1 by being threaded.The end of adjusting yoke 1 one ends is provided with connecting hole 6, is used for being hinged of adjusting yoke 1 and oil pumper brake control link.
Operating principle: stop oil pumper operation at needs, when carrying out corrective maintenance, adjustment, replacing or oil well operation, can pull brake lever, effect by adjusting yoke 1, fixed bearing 3 and back-moving spring 2, the openend of brake hoop 7 is closed up to the centre, brake wheel is held tightly, oil pumper is out of service.At this moment, rotatable lock jack panel 5 makes it move in the U type baffle plate 4 from the nearer sides of brake hoop 7 along adjusting yoke 1, and will brake by the barrier effect of U type baffle plate 4 and to bind round 7 and be locked at braking state.Even if occur that mistake is bumped, ratchet, ratchet in the loose brake lever of mistake or the brake control mechanism break down, brake hoop 7 can not get loose yet, and avoids the generation of machinery, personal injury thus.When corrective maintenance, adjustment, replacing or oil well operation finish, when needing to start the oil pumper operation, as long as with spanner rotation lock nut 5, it is moved in the U type baffle plate 4 along adjusting yoke 1 bind round 7 sides far away from brake, unclamping brake lever then, by the thrust of back-moving spring 2, brake hoop 7 can be unclamped, start the oil pumper running.
Claims (2)
1, a kind of oil pumper brake locking device, it is characterized in that: it has one and installs the adjusting yoke that is connected with brake hoop, be set with back-moving spring, fixed bearing and U type baffle plate on it, the locking nut that is used to lock the brake hoop is housed on the adjusting yoke of baffle plate inside line, and adjusting yoke stretches out the connecting hole that an end is provided with and the control link that brakes is assembled of U type baffle plate.
2, oil pumper brake locking device according to claim 1, it is characterized in that: described pull bar adopts full thread shaft-like.
