In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a device for fixing a pumping unit provided in an embodiment of the present invention, fig. 2 is a schematic usage diagram of a device for fixing a pumping unit provided in an embodiment of the present invention, please refer to fig. 1 and fig. 2, the device for fixing a pumping unit is used for connecting a pumping unit base a and a concrete foundation B, and the device includes: the device comprises a stud 1, a ball seat 2, a ball head 3 and a first nut 4; the lower end of the stud 1 is fixed in a mounting hole of the concrete foundation B through a foundation connector 5, and the upper end of the stud sequentially penetrates through a connecting hole of the pumping unit base A, the ball seat 2 and the ball head 3 to be connected with the first nut 4; the upper end of the ball seat 2 is provided with an arc-shaped groove matched with the outline of the ball head 3; the first nut 4 can be screwed down until the ball head 3 is seated into the arc-shaped groove of the ball seat 2.
In the process of using the device to install the oil pumping unit, the base connector 5 is usually fixed in the mounting hole of the concrete foundation B, then the connecting hole on the oil pumping unit base A is aligned with the mounting hole of the concrete foundation B, and the lower end of the stud 1 is inserted into the connecting hole on the oil pumping unit base A. And adjusting the inclination of the stud 1 to enable the bottom of the stud 1 to be tightly connected with the base connector 5, wherein the inclination of the stud 1 depends on the dislocation relation between the mounting holes of the pumping unit base A and the concrete base B, and when the connecting hole on the pumping unit base A is completely overlapped with the mounting hole of the concrete base B, the stud 1 is just mounted in the vertical direction. After that, the ball seat 2, the ball head 3 and the first nut 4 are sequentially inserted into the stud 1, so that the bottom surface of the ball seat 2 is abutted to the upper surface of the base A of the pumping unit, after the position between the ball seat 2 and the ball head 3 is adjusted, the ball head 3 and the ball seat 2 are contacted through an arc-shaped groove, and the ball head 3 and the ball seat 2 rotate relatively, so that the stud 1 and the ball head 3 are in an inclined state, the first nut 4 can still be used for compressing the ball head 3, and the first nut 4 is screwed.
Through set up the bulb on the double-screw bolt and with the ball seat of this bulb adaptation, install this ball seat on the base of beam-pumping unit, when the hole between this base and the basis is unaligned, lead to the relative this base slope of this double-screw bolt, because through the arc wall contact between this bulb and this ball seat, through the relative rotation between this bulb and this ball seat, make under the condition that this double-screw bolt and this bulb are in the tilt state, still can use this first nut to compress tightly this bulb, can be fast convenient zonulae occludens this base and this basis, and the intensity of this connection form is higher.
In a possible design, the upper and lower end faces of the ball head 3 are both planar structures, and the diameter of the upper end face of the ball head 3 is larger than that of the lower end face.
The above structure facilitates the installation of the ball head 3 from the upper end surface of the ball seat 2, and the side surface of the ball head 3 is arc-shaped to match with the arc-shaped groove of the ball seat 2, so as to facilitate the rotation of the ball head 3 in the ball seat 2, for example, the side surfaces of the arc-shaped groove and the ball head 3 may be a spherical part with the same diameter.
In one possible design, the upper end surface of the ball head 3 protrudes from the arc-shaped groove of the ball seat 2. So that the first nut 4 can be screwed down to a position where the ball head 3 is tightly pressed against the ball seat 2, and the device can firmly fix the pumping unit base A and the concrete foundation B.
In one possible design, the apparatus further includes: a gasket 6 sleeved on the stud 1; the washer 6 is located between the ball 3 and the first nut 4. The gasket 6 is used to enlarge the contact surface between the first nut 4 and the ball head 3, and prevent the abrasion of the upper surface of the ball head 3 caused by the friction between the first nut 4 and the ball head 3 in the screwing process.
In one possible design, the cross-sectional area of the washer 6 is greater than the maximum cross-sectional area of the ball head 3. The gasket 6 completely covers the surface of the ball head 3, and is used for protecting the upper surface of the ball head 3, preventing dust or debris from entering the contact surface between the ball head 3 and the ball seat 2, and ensuring smooth relative sliding between the two. Specifically, the outer shape of the gasket 6 may be a cylinder or a rectangular parallelepiped.
In one possible design, the apparatus further includes: a second nut 7 sleeved on the stud 1; the second nut 7 abuts against the upper end surface of the first nut 4.
The second nut 7 and the first nut 4 form interlocking, so that the first nut 4 is prevented from loosening, and the fastening effect on the ball head 3 is enhanced.
In one possible design, the base connection head 5 is screwed to the threaded stud 1. The base connector 5 is provided with a through hole, an internal thread is arranged in the through hole, an external thread matched with the internal thread is arranged at the bottom end of the stud 1, the threaded connection is convenient to screw or disassemble, and the mechanical property is good.
In one possible embodiment, the base connection head 5 is of a prismatic or circular truncated cone structure.
The side wall and the bottom wall of the foundation connector 5 are at a certain angle, so that when the foundation connector 5 and the stud 1 are obliquely installed together, the foundation connector 5 can still be tightly abutted against the installation hole of the concrete foundation B by means of the side wall, and the tightness of connection between the foundation connector 5 and the concrete foundation B is improved. The angle can be set based on the dislocation between the mounting hole of the concrete foundation B and the connecting hole of the pumping unit base a, and for example, the angle can be 1 to 5 degrees. Specifically, the base connector 5 may be a quadrangular frustum, a hexagonal frustum, an octagonal frustum, or the like.
In one possible design, the base connector 5 is provided with a resistance-increasing projection 51 on its outer side wall. The fastening connection between the foundation connector 5 and the mounting hole of the concrete foundation B is further facilitated, and the bolt is prevented from falling off.
In one possible design, the resistance-increasing protrusion 51 is integrally formed with the base connector 5. The processing procedures are reduced, and the processing cost is reduced.
Above-mentioned all optional technical scheme can adopt arbitrary combination to form the optional embodiment of this utility model, and the repeated description is no longer given here. The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
