Abstract
The utility model discloses a balance weight structure of a vertical oil extractor, which is a combined balance weight box body structure. Each group of balance weight box body of the combined balance weight box body structure is formed by connecting an upper box body, a middle-upper box body, a middle-lower box body and a lower box body, wherein the upper box body is connected with the middle-upper box body by a bolt, and the middle-lower box body is connected with the lower box body by another bolt; a suspension rod is fixed at the lower part of the middle-upper box body, a hook which can rotate on a rotating shaft is installed at the upper part of the middle-lower box body, and the middle-lower box body is suspended on the suspension rod by the hook and connected with the middle-upper box body. The structural form that the hook is connected with the suspension rod can be adopted between every two groups of balance weight box bodies as well as between the middle-upper box body and the middle-lower box body of each group of balance weight box body. The weight balance structure not only has the advantage of not using a crane or other large hoisting devices when balance weight is adjusted, but also has the advantages of being reliable in connection, convenient in operation, time-saving and labor-saving as well as reusable.
Description
Technical field
The utility model relates to a kind of counter weight construction that is used for vertical oil-pumping machine, belongs to the counterweight technology field of vertical oil-pumping machine.
Background technology
At present, the counter weight construction of oil pumper generally all is the frame mode that adopts casting pig or other counterweight to form in the prior art, because the counterweight of oil pumper needs to make the counterweight adjustment according to the oil well situation, and existing these modes all need to employ crane or other large-scale hanging apparatus are dismantled, so not only exist problem time-consuming, effort, but also exist the inconvenient problem of attended operation.Therefore the result of use of existing oil pumper counter weight construction still is not ideal enough.
The utility model content
The utility model purpose is: provide a kind of when regulating counterweight without crane or other large-scale hanging apparatus and connect counter weight construction reliable, easy to operate, time saving and energy saving and can reusable vertical oil-pumping machine, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: the counter weight construction of this vertical oil-pumping machine is a combined type ballast box body structure, every set of weights casing of this combined type ballast box body structure is connected to form by upper box, middle upper box, middle lower box and lower box, upper box is connected by bolt respectively with lower box with middle upper box and middle lower box, bottom at middle upper box is fixed with peg, on the top of middle lower box the hook that can rotate in rotating shaft is housed, middle lower box hangs on the peg by hook and is connected with middle upper box.
On middle lower box, be provided with and link up with the return spring that is connected, and on hook, also be connected with quick decomposition pull bar.
Bottom at middle upper box is provided with gathering sill, is provided with the reset guide bar that matches with gathering sill on the top of middle lower box.
Be arranged with the cross-arm beam of two telescopic types respectively on the both sides of lower box.
Be provided with the belt connecting device that can be connected with the vertical oil-pumping machine belt in the upper end of the upper box of going up a set of weights casing most.
Be provided with the hook installing rack that can be used for installing hook on the top of upper box.
Be provided with the peg installing rack that can be used for installing peg in the bottom of lower box.
Owing to adopted technique scheme, the utility model is between every set of weights casing and the frame mode that all adopts hook to be connected with peg between the middle upper box of every set of weights casing and the middle lower box, therefore the utility model compared with prior art, the utility model not only has when regulating counterweight the advantage without crane or other large-scale hanging apparatus, connects reliable, easy to operate, time saving and energy saving and can reusable advantage but also have.
When using the utility model, when carrying out the operation splitting of knockdown counterweight casing, at first four cross-arms taking-ups with lower box are placed on the following fence of oil pumper, manually pull out quick decomposition pull bar, hook is rotated and the disengaging peg, at this moment the motor that starts vertical oil-pumping machine is pulled upwardly upper box and middle upper box, at this moment can unclamp pulling and decompose the hand of pull bar fast, thereby finish the decomposition of counterweight casing.
When carrying out the connection of knockdown counterweight casing, the vertical oil pumping motor of control upper box and middle upper box with linking together slowly puts down earlier, in treating under the guiding of the reset guide bar of upper box on its gathering sill and middle lower box to drop on the accurate contraposition of middle lower box on the lower box in, its peg bumps out earlier hook, after waiting to put in place, hook hangs on the peg under the effect of return spring automatically, thereby the ballast box of upper box and middle lower box is connected work in finishing, connect finish after, four cross-arms of lower box are pushed back in its casing reset again.
