Description
Technical field
The utility model is related to petroleum machinery equipment technical field and in particular to a kind of totally-enclosed long stroke pumping unit counterweight
The guiding mechanism of case.
Background technology
Oil pumper be exploitation oil a kind of machinery equipment, current oil extraction in oil field mostly adopt beam pumping unit, oil in
This balance of well pumping unit degree is low, wastes the electric energy of electricity greatly, and therefore people develop tower shelf type oil pumping machine,
Existing pylon counterweight of oil pumping unit case is square box structure, and by steel plate welding fabrication, nowel fixed weight, balancing weight is put
Put in ballast box body and be used for adjusting counterweight, be provided with guide wheel and slideway in the both sides of ballast box, using 4 on every counterweight of oil pumping unit case
Part guide wheel is spacing, although the stability that the guider of this structure solves ballast box work is fixed, with DP technology
Constantly develop, demand increases in cumulative year after year, the stroke of oil production machine, and the guiding mechanism of existing ballast box just can not meet oil recovery
The demand of equipment, often the empty state of commutation directive wheel rotation at present in use, so that ballast box can not be balanced and move down
Dynamic, dancing occurs, causes to damage the parts such as guiding mechanism.Life-span is shorter, changes difficult, and high cost.
Content of the invention
The purpose of this utility model is to provide a kind of guiding mechanism of totally-enclosed long stroke pumping unit ballast box, and it runs peace
Entirely reliable, life-span length, maintenance cost is low, installs also easy and convenient, and structure is simple, solves tower shelf type oil pumping machine ballast box and runs
When guide frame be easily damaged, change difficult, the problems such as guide rail adjustment difficulty is larger.
In order to solve the problems of prior art, the utility model is to employ the following technical solutions：The utility model
A kind of totally-enclosed long stroke pumping unit ballast box guiding mechanism, including ballast box, the hanger that is arranged on hanging beam top, symmetrically
It is arranged on ballast box both sides directive wheel and rolls, with directive wheel, the slideway being connected, be arranged on the cyclic track of counterweight lower box part, its
Be characterised by described directive wheel by be symmetricly set on the upper righting directive wheel of ballast box both sides, middle load-bearing directive wheel and under hold
Be redirected wheel composition, described upper righting directive wheel is arranged on hanging beam top both sides by upper directive wheel connecting seat, described in
Between load-bearing guide wheel be arranged on the top of cyclic track by middle directive wheel connecting seat, described lower load-bearing directive wheel is by lower guiding
Wheel connecting seat is arranged on the bottom of cyclic track.
Further, described upper directive wheel connecting seat is square plate, is provided with triangle in the side of square plate and strengthens
Plate, described triangular reinforcing plate one right-angle side is welded with square plate, and another right-angle side is welded on hanging beam top, in square bar
Guide wheel axis hole is had on plate, guide wheel shaft is placed in spindle guide wheel in the hole.
Further, described righting directive wheel, middle load-bearing directive wheel and lower load-bearing directive wheel are all by bearing and guide wheel
Axle connects.
The beneficial effects of the utility model are：
It is mounted with upper, middle and lower three directive wheel because the utility model employs in the both sides of ballast box, especially middle
Load-bearing directive wheel and lower load-bearing directive wheel are symmetricly set on cyclic track, make ballast box uniform force when moving up and down, have
When solving the problems, such as that totally-enclosed long stroke pumping unit ballast box runs to effect, guide frame is easily damaged.Another, due to will be upper
Righting wheel is arranged on hanging beam, so that righting directive wheel and the distance of middle other middle load-bearing directive wheels and lower load-bearing directive wheel is drawn
Long, righting effect is more preferable.Ensure that oil pumper can operate steadily under any circumstance, improve guiding mechanism and use the longevity
Life.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A profile construction principle of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the guiding mechanism of a kind of totally-enclosed long stroke pumping unit ballast box of the present utility model, bag
Include ballast box 1, be arranged on the hanger 3 on hanging beam 12 top, be symmetricly set on ballast box 1 both sides directive wheel and roll even with directive wheel
The slideway 6 connecing, is arranged on the cyclic track 9 of ballast box 1 bottom it is characterised in that described directive wheel is by being symmetricly set on counterweight
The upper righting directive wheel 5 of case both sides, middle load-bearing directive wheel 7 and lower load-bearing directive wheel 11 form, described upper righting directive wheel 5
Hanging beam 12 top both sides are arranged on by upper directive wheel connecting seat 4, due to being arranged on upper righting wheel on hanging beam, so that righting is led
Distance to wheel and middle other middle load-bearing directive wheels and lower load-bearing directive wheel is elongated, and righting effect is more preferable；Described centre is held
Weight guide wheel 7 is arranged on the top of cyclic track 9 by middle directive wheel connecting seat 8, and described lower load-bearing directive wheel 11 is led under passing through
It is arranged on the bottom of cyclic track 9 to wheel connecting seat 10.Middle load-bearing directive wheel and lower load-bearing directive wheel are symmetricly set on circulation
