Abstract
A fracturing truck unloading tool is used to mainly solve the problems of wasting of time and effort to replace the high pressure pump plunger sleeve of the fracturing truck, low replacement efficiency and high replacement cost. It is characterized in that: the upper terminal of a silk pole(1) is connected with a screw(2) which has a hole(9) in the radial direction, the lower ball end ferrule of the silk pole(1) is clamped in the concave groove(4) of two semicircle slips(3), lock rings(5) are disposed in the upper terminals of the two slips(3), pressure caps(6) are arranged out of the upper terminals of the two slips(3), convexities are disposed on the lower and the upper terminal of the slips(3) and cited obliqueness(10), a pressure-retraining base is installed on the silk pole(1) and the lower terminal of the screw(2). The fracturing truck unloading tool has advantages of saving time and effort, high replacement efficiency and low replacement cost.
Description
Technical field:
The utility model relates to the used maintenance tool of oil recovery field, oil field fracturing unit truck, and especially fracturing unit truck unloads pump tool.
Background technology:
In order to improve the amount of gathering, need carry out fracturing work in the field, oil field to down-hole formation.And fracturing work just need be used fracturing unit truck.By the high-pressure pump on the fracturing unit truck fracturing fluid is pressed into the stratum.The fracturing unit truck high-pressure pump is because long-term the use causes plunger watt cover serious wear at present, this just needs periodic replacement plunger watt cover, because fracturing unit truck is an import equipment, when changing plunger watt cover, there is not specific purpose tool, causing when changing wastes time and energy, replacing efficient is low, and the replacement cost height is unfavorable for applying.
The utility model content:
Waste time and energy in order to solve a replacing fracturing unit truck high-pressure pump plunger watt cover, it is low to change efficient, the problem that replacement cost is high, the utility model provides a kind of fracturing unit truck to unload pump tool, this fracturing unit truck unloads pump tool and has time saving and energy savingly, changes the efficient height, the characteristics that replacement cost is low.
The technical solution of the utility model is: this fracturing unit truck unloads pump tool and comprises screw mandrel, the screw mandrel upper end is connected with radially the screw of removing the hole, screw mandrel lower end bulb cutting ferrule is in the groove of the circular slips of two halves, two slips have lock ring in the upper end, two slips have gland outside the upper end, oblique upper end is drawn in the slips lower end boss, is with Pressure Block on the screw mandrel of screw lower end.
On the screw mandrel between gland and Pressure Block, be with weight in the such scheme.
The utlity model has following beneficial effect: this fracturing unit truck unloads pump tool owing to take such scheme, can easily take out plunger watt cover by such scheme, thereby reduce labor strength, time saving and energy saving, improved replacing efficient, reduced replacement cost, helped applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-screw mandrel among the figure, the 2-screw, the 3-slips, the 4-groove, the 5-lock ring, the 6-gland, the 7-Pressure Block, the 8-weight, 9-removes the hole, and 10-draws tiltedly, the 11-boss.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this fracturing unit truck unloads the pump tool bag and comprises screw mandrel 1, screw mandrel 1 upper end is connected with radially the screw 2 of removing hole 9, screw mandrel 1 lower end bulb cutting ferrule is in the groove 4 of the circular slips 3 of two halves, have in two slips, 3 upper ends outside lock ring 5, two slips 3 upper ends gland 6 is arranged, oblique 10 upper ends are drawn in slips 3 lower ends boss 11, be with Pressure Block 7 on the screw 2 lower end screw mandrels 1, be with weight 8 on the screw mandrel 1 that gland 6 and Pressure Block are 7.
During actual the use, at first two slips 3 are placed in the pump cylinder, make the boss 11 of two slips, 3 lower ends be stuck in plunger watt cover lower end, again screw mandrel 1 lower end bulb is placed in the groove 4 of two slips 3, then lock ring 5 is placed in two slips, 3 upper ends, at this moment can utilize weight 8 to force lock ring 5 to put in place smoothly, and gland 6 is enclosed within outside two slips, 3 upper ends, again with 7 of Pressure Blocks at pump cylinder mouth place, at last moving rod is inserted the removing in the hole 9 of screw 2, move screw 2 by moving rod and rotate, because the rotation of screw 2 moves up screw mandrel 1, because screw mandrel 1 lower end bulb cutting ferrule in the groove 4 of slips 3, makes a plunger watt cover shift out from pump cylinder, reach the purpose of changing plunger watt cover.Thereby reduced labor strength, time saving and energy saving, improved replacing efficient, reduce replacement cost, and structure is single, helps applying.This fracturing unit truck unloads pump tool and has time saving and energy savingly thus, changes the efficient height, the characteristics that replacement cost is low.
Claims (2)
1, a kind of fracturing unit truck unloads pump tool, comprise screw mandrel (1), it is characterized in that: screw mandrel (1) upper end is connected with radially the screw (2) of removing hole (9), screw mandrel (1) lower end bulb cutting ferrule is in the groove (4) of the circular slips of two halves (3), two slips (3) have lock ring (5) in the upper end, two slips (3) upper end is covered with gland (6), and draw tiltedly slips (3) lower end has boss (11) on (10), is with Pressure Block (7) on screw (2) the lower end screw mandrel (1).
2, fracturing unit truck according to claim 1 unloads pump tool, it is characterized in that: be with weight (8) on the screw mandrel (1) between gland (6) and Pressure Block (7).
