Abstract
The utility model discloses a hydraulic power clamp pliers hand squeezing prevention apparatus using in oil industry. The utility model is used for the workover treatment engineering of the oil field. The apparatus is composed of a protective door part and a connection fixing part. The utility model is installed on the front end of the clamp pliers opening of the hydraulic power clamp pliers to make a guard device arranged at the point of the clamp pliers opening of the hydraulic power clamp pliers. The utility model can prevent the fingers of the manipulator from miss-going into the apparatus effectively. When the pair of hydraulic power clamp pliers rotates, the protective door part is in the normal closed state. When a fuel tube enters in and exits from the clamp pliers opening of the hydraulic power clamp pliers, the pair of hydraulic power clamp pliers opens an arc door leaf and a door board depending on the impact force itself. Thereby, the arc door leaf and the door board are closed automatically, and the normal operation is not influenced. The utility model prevents the fingers of the manipulator from entering the clamp pliers opening of the hydraulic power clamp pliers when the accident and the uncertain factor are taken place, therefore, the utility model avoids the accident generation of squeezing injury or edging out the fingers of the manipulator.
Description
Technical field
The utility model relates to the workover rig of petroleum industry, and particularly the hydraulic power tongs anti-squeezing hand device is applicable to the oil well workover engineering.
Technical background
In the oil well workover work progress, hydraulic screw-on machine is an instrument of going up oil discharge pipe, goes up oil discharge pipe's screw thread when being used for putting oil pipe.Hydraulic power tongs is installed in well head, at the hydraulic power tongs front end one jaw is arranged, and from then on fuel feed pump passes in and out.Because this jaw place lacks effective safety device, in use, often because various accidental causes cause operator's finger to be strayed into wherein, the accident of hindering and squeezing out operator's finger takes place to squeeze.Not only causing the injury of great body and mind to the operator, also cause enormous economic loss to enterprise, is that this equipment is and treats improved part.
Summary of the invention
The purpose of this utility model is to make a kind of safe and reliable, easy to operate, hydraulic power tongs anti-squeezing hand device that the automatic protection ability is strong.Overcome the shortcoming of existing equipment, avoid squeezing the generation of hand accident, guarantee operator's safety, protection worker's physical and mental health and healthy reduces the economic loss of enterprise, increases economic efficiency.
The present technique solution can reach above-mentioned purpose: the hydraulic power tongs anti-squeezing hand device by protective door part be connected and fixed part and form, is installed in the jaw front end of hydraulic power tongs.
After using the utility model, there has been protector at the jaw place of hydraulic power tongs, can prevent effectively that operating personnel's finger is strayed into wherein.During the hydraulic power tongs rotation, under the effect of torque spring, protective door part is in normally off automatically, prevents that operator's finger from entering hydraulic power tongs jaw place when meeting accident uncertain factor, thereby has avoided crowded wound or squeezed out the generation of operator's finger accident.Because it is the arc door leaf of protective door part is the goat's horn shape, identical in addition with oil pipe arc angle, during contact the arcwall face contact, during oil pipe turnover hydraulic power jaw place, by self impact arc door leaf and door-plate are opened, auto-closing does not influence normal running immediately.The utility model is safe and reliable, easy to operate, has protected worker's physical and mental health and healthy, has avoided causing the body and mind injury to the worker, has useful effect to stablizing the workforce, has reduced the economic risk that enterprise bears for this reason.
Description of drawings
Fig. 1 is the vertical view of the utility model protective door part-structure schematic diagram.
Fig. 2 is the front view that the utility model is connected and fixed the part-structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing 1 and accompanying drawing 2, the hydraulic power tongs anti-squeezing hand device by protective door part be connected and fixed part and form, is installed in jaw 3 front ends of hydraulic power tongs.The protective door part is made up of arc door leaf 6, door-plate, junction plate and upper and lower fixing plate 4 and 2, and arc door leaf 6 is fixedlyed connected with door-plate, and door-plate and junction plate are provided with shaft hole, interior dress rotating shaft 5.Arc door leaf 6 is the fan-shaped frame of inner arc or the inner arc fanning strip of symmetry; Door-plate is the symmetrical closure plate that conforms to the base shape of hydraulic tongs jaw 3 and arc door leaf 6.Be connected and fixed the part form by involutory spring body 1 and bottom plate 2, bottom plate 2 is loaded on the upper end of spring body 1, it is corresponding about in the of 4 with upper mounted plate that bottom plate 2 is provided with fixing hole, in wear rotating shaft 5, be fixed on hydraulic power tongs jaw 3 places.By rotating shaft 5, the protective door of this device part combines with being connected and fixed partly.Spring body 1 is made up of rotating shaft 5, rotating shaft fixed head, torque spring, folding and torque spring hold-down nut, rotating shaft 5 is fixed on the rotating shaft fixed head, is set in the torque spring, under adorn the torque spring hold-down nut, wrap up in folding outward, the other end of torque spring is fixed in the end of folding developed surface.During on-the-spot the use, oil pipe turnover hydraulic power tongs is opened the arc door leaf 6 and the door-plate of this device by self impact, and under the effect of torque spring, the arc door leaf 6 of protective door part and door-plate are closed immediately in spring body 1.Do not influence normal running, effectively protect operator's personal safety.
