The device rotates and moves up and down flexibly, is convenient in operation, is applicable to adding of packing or belts, not only solves the problem of adding of packing or belts but also the problem of taking out of packing or belts, allows packing or belts to be replaced quickly, and is time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of oilfield well head packing filling machine, and specifically a kind of beam-pumping unit portal disc radical is dosed device.
Background technology
In present oil exploitation, oil pumping polish rod is done in mouth of pumped oil well and is pumped, and sealing is between the two realized by the wellhead sealing device that packing is housed.Must change packing if packing is just revealed, at present, generally adopt and add the waste and old belt of oil pumper as the packing substitute.Because belt is thicker, harder, dose difficulty larger, and in dosing process, easily hurt operating personnel's hand, also can hurt polished rod smooth surface, sealer screw thread etc., simultaneously, owing to dosing for a long time packing, also might cause the more serious production accident such as sand card, wax card of oil well.
Chinese patent 200820173501.X disclosed " beam-pumping unit portal disc radical is dosed device " is comprised of pressing mechanism and slips.It is little that this design is pressed into moment to packing, is unfavorable for that belt adds; Chinese patent 201020604804.X disclosed " belting pumping unit well-head packing feeding device " is comprised of U-shaped precession device and U-shaped well head fixator, uses screw thread power to add, and interpolation speed is slow, inconvenient operation.
Summary of the invention
The utility model is to provide a kind of beam-pumping unit portal disc radical to dose device for sealer adds packing, solve above-mentioned prior art dose the packing hard problem.
A kind of beam-pumping unit portal disc radical is dosed device, be pressed into collet head and form by fixed card, arm bar, moment conductive bar, airtight and watertight padding, it is characterized in that: rotary moveable fixed card bottom cylindrical is provided with concave groove, U-shaped being fastened in concave groove, arm bar connects by active pin shaft with the moment conductive bar, airtight and watertight padding is pressed into collet head and connects by active pin shaft with the moment conductive bar, arm bar be connected cartoon and cross active pin shaft and connect.
Fixed card is that two hollow semicircular body form, and is connected connection with Rapid connecting bolt by active pin shaft, and hollow semicircular body inner chamber is equipped with rubber.
It is that two hollow semicircular body form that airtight and watertight padding is pressed into collet head, is connected connection with Rapid connecting bolt by active pin shaft; Wherein a hollow semicircular body bottom is provided with rectangular channel, and the openend of rectangular channel is provided with a convex arc cone point.
The utility model is dosed device rotation and up and down reciprocatingly flexibly movable, easy to operate, and is all applicable to adding packing or belt.Not only solved the interpolation problem of packing or belt, also solved simultaneously the taking-up problem of packing or belt, the packing that turns clockwise is dosed device and just belt is compressed into, and is rotated counterclockwise packing and doses device and just packing or belt are taken out, change packing or belt quick, time saving and energy saving.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model fixed card;
Fig. 3 is the structural representation that in the utility model, airtight and watertight padding is pressed into collet head.
The specific embodiment
As shown in Figure 1, the utility model is pressed into collet head 5 by fixed card 2, arm bar 3, moment conductive bar 4, airtight and watertight padding and forms, fixed card 2 bottom cylindricals are provided with concave groove 10, U-shaped card 7 is enclosed within concave groove 10, arm bar 3 is connected with the moment conductive bar by active pin shaft 6b connection, airtight and watertight padding is pressed into collet head 5 is connected with the moment conductive bar and connects by active pin shaft 6c, arm bar 3 be connected card 7 and connect by active pin shaft 6a.
As shown in Figure 2, fixed card 2 is that two hollow semicircular body form, and is connected involutory connection with Rapid connecting bolt by active pin shaft 8, and hollow semicircular body inner chamber is equipped with rubber 11.
As shown in Figure 3, it is that two hollow semicircular body form that airtight and watertight padding is pressed into collet head 5, is connected involutory connection with Rapid connecting bolt by active pin shaft 12; Wherein a hollow semicircular body bottom is provided with rectangular channel 14, and the openend of rectangular channel 14 is provided with a convex arc cone point 15.
When using the utility model to add or taking out belt, at first fixed card 2 is buckled on polished rod 1, screws attaching nut 9, fixed card 2 is pressed on polished rod, whole packing is dosed device position, the rubber 11 in fixed card 2 can prevent that fixed card 2 is involutory and tighten rear damage polished rod 1; Airtight and watertight padding is pressed into collet head 5 is buckled on polished rod 1, screw attaching nut 13, airtight and watertight padding is pressed into the hollow diameter of collet head 5 greater than polished rod 1 external diameter, and airtight and watertight padding is pressed into collet head 5 and can up and down reciprocatingly moves with left rotation and right rotation; By pull force armed lever 3 upwards, by the transmission of active pin shaft 6b, active pin shaft 6c and moment conductive bar 4, airtight and watertight padding can be pressed into to carry on collet head 5 and shift out sealer, belt is placed in sealer by rectangular channel 14 places that airtight and watertight padding is pressed into collet head 5.Then by subordinate a pressure and the power armed lever 3 that turns clockwise, another is held tight belt and is pushed away inward gently, is pressed into the arc shaped surface of collet head 5 and sharp 15 reverse side of its convex arc cone along the power of belt by airtight and watertight padding, belt is pressed onto the end in sealer.When being rotated counterclockwise power armed lever 3, be pressed into collet head 5 by airtight and watertight padding and old belt or packing can be taken out with its convex arc cone point 15, change the packing convenient power-saving.
