Description

Easy-to-mount drilling pump clip
Technical field
This utility model belongs to oil gas drilling-production equipment technical field, relates to a kind of easy-to-mount drilling pump clip.
Background technology
Clip is the heavy connection of drilling pump, and its Main Function is power end intermediate draw bar and fluid end piston rod to be linked together.Piston rod is one of drilling pump consumable accessory, must dismantle clip when changing piston rod, and its easy accessibility governs the maintenance of drilling pump, service efficiency.At present, the clip that drilling pump is commonly used is as it is shown in figure 1, there is following drawback in this kind of structure: dismounting is inconvenient, needs two bolts of degree of tightness, waste time and energy during attended operation, and this certainly will affect drilling pump or even the work efficiency of a whole set of rig.
Summary of the invention
The purpose of this utility model is to provide a kind of easy-to-mount drilling pump clip, solves to dismount in prior art the problem that clip is wasted time and energy.
The technical solution adopted in the utility model is, a kind of easy-to-mount drilling pump clip, including epivalve and hypovalve, epivalve and hypovalve are provided with two fixing ends, before and after the fixing end in the same side of epivalve and hypovalve, two sides is respectively arranged with a connecting plate, front and back the lower perforation of connecting plate is hinged with hypovalve commonly through bearing pin one, and front and back the upper perforation of connecting plate is hinged with epivalve commonly through bearing pin two;
The fixing end of the opposite side of epivalve and hypovalve uses hasp structure, is i.e. provided with eyelet bolt by bearing pin three on hypovalve, has the bayonet socket corresponding with eyelet bolt at epivalve, and eyelet bolt external end head is provided with nut.
Easy-to-mount drilling pump clip of the present utility model, is further characterized in that:
Bearing pin one, bearing pin three and bearing pin two two ends are separately installed with a circlip for shaft.
Nut is configured with corresponding backing plate.
The beneficial effects of the utility model are, tightly need to operate a bolt when dismounting clip and can complete the disengagement of intermediate draw bar and piston rod or be connected, time saving and energy saving, simple and reliable, to reach Fast-Maintenance drilling pump, significantly reduce labor strength, improve drilling pump maintenance, service efficiency.
Accompanying drawing explanation
Fig. 1 is the yoke configurations schematic diagram of prior art;
Fig. 2 is (use state) of the present utility model structural representation;
Fig. 3 is the schematic cross-section of this utility model drilling pump clip.
In figure, 1. epivalve, 2. hypovalve, 3. connecting plate, 4. bearing pin one, 5. circlip for shaft, 6. eyelet bolt, 7. nut, 8. backing plate, 9. bearing pin two, 10. bearing pin three.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
As it is shown in figure 1, the structure of prior art clip is, including epivalve 1, the hypovalve 2 of clip, achieved a fixed connection by two groups of bolts after epivalve 1 and hypovalve 2 make-up.During installation, first the positioning table of intermediate draw bar and piston rod is linked together, then epivalve 1 and hypovalve 2 are placed in intermediate draw bar and piston rod junction, re-tighten two groups of bolts.During dismounting, first unclamp two groups of bolts, then epivalve 1 and the hypovalve 2 of clip are separately laid down.
As shown in Figure 2 and Figure 3, structure of the present utility model is, including epivalve 1 and hypovalve 2, epivalve 1 and hypovalve 2 are provided with two fixing ends, before and after the fixing end in the same side of epivalve 1 and hypovalve 2, two sides is respectively arranged with a connecting plate 3, front and back the lower perforation of connecting plate 3 is hinged with hypovalve 2 commonly through bearing pin 1, and front and back the upper perforation of connecting plate 3 is hinged with epivalve 1 commonly through bearing pin 29;
The fixing end of the opposite side of epivalve 1 and hypovalve 2 uses hasp structure, i.e. on hypovalve 2, by bearing pin 3 10, eyelet bolt 6 is installed, having the bayonet socket corresponding with eyelet bolt 6 at epivalve 1, eyelet bolt 6 upper end (external end head) is provided with nut 7, and nut 7 is configured with corresponding backing plate 8.
It is separately installed with a circlip for shaft 5 at bearing pin 1, bearing pin 29 and bearing pin 3 10 two ends and realizes spacing.
Using method of the present utility model is, first makes the epivalve 1 of clip and hypovalve 2 to being buckled in intermediate draw bar and piston rod junction, is then rotated to epivalve 1 bayonet socket around bearing pin 3 10 by eyelet bolt 6, installs backing plate 8, upper jack panel 7,.Demounting procedure is contrary with installation steps.
