Abstract
The utility model discloses an adjuvant device for detaching a drill pump piston, The adjuvant device has a mouth-clipped seat (1) which can be fixed on the drill pump pedestal; the mouth-clipped seat (1) is hinged with a clipping cover (3) via a hinge axle (2), another hinge axle (6) is on the mouth-clipped seat (1) and hinged with the lower end of a bolt (5), and a nut (4) coordinates with the bolt (5). The adjuvant device is characterized in that an internal hexagonal hole (7) is formed after the mouth-clipped seat (1) and the clipping cover (3) are closed. The utility model has the advantages that the internal hexagonal hole formed by the closure of the mouth-clipped seat and the clipping cover matches the hexagonal axle section on the piston rod, holding the piston rod; the piston and the piston rubber sheet can be conveniently detached, replaced and maintained by one person. Compared with the prior art that at least two persons are needed to detach, replace and maintain pistons, the utility model is simplified to be accomplished by only one person, making the advantage so obvious.
Description
Technical field
The utility model belongs to a kind of drilling pump attachment tools, and definite saying is a kind of servicing unit of dismantling wellbore pump piston.
Background technology
For the piston of drilling pump, because its condition of work is abominable, situ of drilling well needs often to change piston rubber and piston.All be that at least two operative employees fix piston rod earlier with two very big special uses or general utility wrench all the time, again piston compression nut screwed down, pull down piston at last.And piston rod is bigger, is example with 3NB-1300 type drilling pump: 80 millimeters of diameter of piston rod, execute-in-place are three to four-player mostly.And because mud, also frequent slippage spanner has influence on the demolition and maintenance and the replacing of piston, and then has influence on drilling progress.In order to address this problem, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model is when overcoming the dismounting of present wellbore pump piston, does not have the instrument of suitable fixed piston rod, carries out rationally, the deficiency of fast quick-detach piston puts forward.
Technical solution of the present utility model is to realize like this, the servicing unit of this dismounting wellbore pump piston, has a bayonet mount [1] that can be fixed on the drilling pump base, bayonet mount [1] connects by a hinge [2] and Ka Gai [3] hinge, upward also have a hinge [6] and the lower end of bolt [5] to be hinged at bayonet mount [1], bolt [5] is gone up and is cooperated a nut [4], it is characterized in that the closed back of bayonet mount [1] He Kagai [3] forms an inner hexagonal hole [7].
Beneficial technical effects of the present utility model is: the interior hexagonal hole that bayonet mount and bayonet socket closure form later on cooperates with the hexagonal shaft part on the piston rod, with the piston rod clamping, can dismantle, change, keep in repair piston and piston rubber easily, and can people's operation.Needing in the past the work simplification of two people dismounting, replacing, maintenance piston at least is a people, and its advantage is conspicuous.
Description of drawings
Accompanying drawing 1 is structure master's schematic views of the present utility model, and accompanying drawing 2 is vertical views of Fig. 1.Sequence number in the accompanying drawings is described as: 1, bayonet mount, 2, hinge, 3, Ka Gai, 4, nut, 5, bolt, 6, hinge, 7, inner hexagonal hole.
The specific embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this device mainly has a bayonet mount [1] that is fixed on the drilling pump base, bayonet mount [1] connects by a hinge [2] and Ka Gai [3] hinge, upward also have a hinge [6] and the lower end of bolt [5] to be hinged at bayonet mount [1], bolt [5] is gone up and is cooperated a nut [4], it is characterized in that the closed back of bayonet mount [1] He Kagai [3] forms an inner hexagonal hole [7].During work, Jiang Kagai raises, and the hexagonal shaft part of reserving on the piston rod is put in the opening of bayonet mount, and it is closed to block lid, compresses with bolt [5] and nut [4] Jiang Kagai, and at this moment, piston rod just has been fixed on this device.Just can dismantle then piston, replacing or maintenance work.If simplified structure, Ka Gai [3] can not be provided with yet.But the bayonet mount of opening [1] opening two point upwards influence work safety.
