Abstract
The utility model relates to a safe mechanical handrail device, comprising a handrail body. At the front end of the handrail body is provided a large semicircular fixed jaw, the opening part of which is hinged with a movable jaw configurated with the fixed jaw. The outer side of the movable jaw is connected with a spring and is hinged with the front end of a clamping rocking arm, the central section of which is hinged with a sliding connection rod. The sliding end of the sliding connection rod is configurated with a sliding chute provided in one side of the handrail body, wherein the tail end of the sliding chute is provided with a limit adjusting device. Between the clamping rocking arm and the sliding connection rod is arranged a locking mechanism. The rear end of the handrail body is provided with a handle. The safe mechanical handrail device of the utility model is simple and reasonable in structure arrangement, reliable in clamping performance, safe in operation, flexible in clamping and dismounting and convenient in utilization and carrying, solving the problem that, to an oil production worker, a tester and a maintenance worker, there is no point for a hand to apply the force and guaranteeing an operator's safety in the producing process of pumping oil wells in oil fields.
Description
Technical field
The utility model relates to a kind of secure mechanical armrest system, particularly a kind of secure mechanical armrest system that is used for the oil field pumping well operation.
Background technology
At present, when relating to the dislodging of test, oil well load of working drawing in the oil field pumping well manufacturing process, operating personnel are that pin steps down on the production tree, hand grip lifting rope or polished rod, another hand are held corresponding instrument and carried out associative operation.The problem that such operating process exists is: when the polished rod slips lost efficacy, when hand does not have origin of force, is easy to take place operating personnel and throws or hand is stuck in the polished rod eye from production tree, cause the generation of personal damage accident.
The utility model content
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and a kind of secure mechanical armrest system that is used for the oil field pumping well operation is provided, not only functional performance is reliable for it, can effectively improve the safety of pumpingh well operation, and the clamping dismounting flexibly, uses easy to carry.
The utility model is that the technical scheme that problem adopted of the above-mentioned existence of solution is: include a handrail body, be provided with the regular jaw of more than half circular arc at the front end of handrail body, the moving jaw of and regular jaw phase configuration hinged at the opening part of regular jaw, the outside of moving jaw connects extension spring and is hinged with the front end that clamps rocking arm, the middle part and the slide link that clamp rocking arm are hinged, the sliding end of slide link and the chute phase configuration that is opened in handrail body one side, tail end at chute is installed means for adjusting limit of movement, and between clamping rocking arm and slide link, be installed on locking mechanism, be installed on handle in the rear end of handrail body.
Press such scheme, described moving jaw inboard is installed on non-slipping block.
Press such scheme, described means for adjusting limit of movement comprise connect firmly the fixedly swivel nut of handrail body tail end and with the fixing adjusting screw(rod) of swivel nut configuration.
Press such scheme, described locking mechanism comprises and is installed in the locking jack of offering on the latch that clamps the rocking arm rear portion and the slide link, the bending latch hook phase configuration on locking jack and the latch.
The utility model will clamp rocking arm when using and draw outward, moving jaw outwards opens under the effect of extension spring, to be held part by the regular jaw opening this moment---and the polished rod die sleeve places in the jaw, to clamp rocking arm then draws in, clamping rocking arm moves forward under the effect of slide link, make the inside rotation of moving jaw tight until being held the part pincers, this moment latch being inserted makes the bending latch hook enter the locking jack, clamping rocking arm is connected with slide link and is locked as one, promptly finish the clamping locking process of armrest system, and means for adjusting limit of movement can be used to regulate the elasticity that jaw clamps.At this moment, armrest system fixedly secures on the polished rod die sleeve, can be used as operating personnel's a fixing handrail, and hand grip handrail can carry out plucking, hang other operation such as load in the test job.After finishing using, extract latch, clamp rocking arm and draw outward, be about to the jaw dismounting that gets loose, can conveniently take away from the scene.
The beneficial effects of the utility model are: 1, structure is provided with advantages of simple, clamps dependable performance, and handling safety has solved oil recovery worker, test worker, hand did not have the problem of origin of force when maintenance mans operated, and ensured the safety of operating personnel in the oil field pumping well manufacturing process; 2, the clamping dismounting is used easy to carry flexibly.
