Description

Technical Field

[0001] The utility model belongs to an adjusting device used for an oil pumping unit motor, in particular to a manual oil pumping unit motor adjusting seat bracket. Background Art

[0002] The beam pumping unit is currently the most common type of oil production equipment. Its power component is a large and heavy three-phase asynchronous motor. During operation, a motor mounting bracket is installed on the pumping unit base, and the three-phase asynchronous motor is mounted on the bracket with fastening bolts. The motors in pumping units operate in harsh environments and conditions. For example, prolonged operation in high or low temperatures can accelerate motor aging and wear, shortening their service life. Another example is the increased load on the motor during the upstroke caused by severe wax deposition on the sucker rod. Overload can cause the motor to operate under high load for extended periods, increasing heat and current draw, thereby shortening its lifespan. In addition, when the mining depth (mining layer) of a well changes significantly, it is also necessary to replace the motor with a different model, so the frequency of motor replacement is also very high. Due to factors such as production batch, model, and manufacturer, the size of the new motor is different from the replaced motor. The main influencing point is the different hole spacing of the motor base. Therefore, the existing motor mounting brackets are processed with "long holes" (for example: Authorization Announcement No.: CN220087062U). The position of the fastening bolts used to fasten the motor to the motor mounting bracket can be adjusted in the long holes to ensure that different motors can be installed. However, vibrations are inevitably generated during the operation of the pumping unit, which will inevitably cause the fastening bolts to loosen. After the fastening bolts are loosened, they can slide in the long holes, causing the position of the motor relative to the motor mounting bracket to change, which directly affects the tightness of the belt. Utility Model Content

[0003] In order to prevent the fastening bolts from sliding in the long holes, the utility model provides a manual oil pump motor adjustment seat bracket. The motor mounting bracket of the utility model is not provided with long holes, and there is no problem of the fastening bolts sliding in the long holes. Although the utility model is not provided with long holes, it can still match the installation of motors with different hole spacings.

[0004] The technical solution provided by the utility model is: a manual oil pumping unit motor adjustment seat bracket, comprising two parallel longitudinal guide rails and two transverse rods, for the convenience of distinction, the two longitudinal guide rails are respectively referred to as longitudinal rails A and longitudinal rails B, the two transverse rods are respectively arranged at the two ends of the longitudinal rails A and longitudinal rails B, wherein the two ends of the longitudinal rail A are respectively fixedly connected to the two transverse rods, and the two ends of the longitudinal rail B are slidably matched with the transverse rods, and two sliding sleeves are respectively slidably installed on the longitudinal rails A and longitudinal rails B, and each sliding sleeve is respectively fixed with a fastening bolt for connecting to the motor base, and the fastening bolts are fastened to different motors through the sliding of the longitudinal rails B and the sliding of each sliding sleeve.

[0005] A further technical solution is: two transverse rods are parallel to each other, and transverse guide rails are slidably mounted inside the two transverse rods. For the sake of distinction, they are respectively called transverse rails A and transverse rails B. Longitudinal rods are respectively provided at both ends of transverse rails A and transverse rails B. The two ends of transverse rails A and transverse rails B are respectively fixedly connected to the longitudinal rods. A worm gear reducer B is fixedly installed on the longitudinal rod close to the longitudinal rail A. One end of the worm in the worm gear reducer B is connected to the longitudinal rail A, so that the movement of the worm directly drives the movement of the longitudinal rail A, and then indirectly drives the movement of the motor.

[0006] A further technical solution is: one end of the two longitudinal rods is hinged to the oil pumping unit frame respectively, and a driving gear set is fixedly installed on the oil pumping unit frame at the other end of the two longitudinal rods. The driving gear set includes two mutually meshing gears A and two mutually separated gears B. Gears A and gears B are coaxially arranged in a one-to-one correspondence, so that the rotation of gear A drives gear B to rotate. A vertically arranged arc-shaped rack is fixed to the lower side of the transverse rod at this end, and teeth are machined on both sides of the arc-shaped rack. The gears on both sides are respectively meshed with the two gears B, so that the rotation of gear B drives the arc-shaped rack to move up and down.

[0007] A further technical solution is: a supporting rod and an inserting rod are respectively fixed between a pair of sliding sleeves at corresponding positions on the longitudinal rails A and B, and the supporting rod and the inserting rod are plugged into each other; a worm gear reducer A is fixedly installed on the transverse rod, and one end of the worm in the worm gear reducer A is connected to the supporting rod or the inserting rod, so that the movement of the worm directly drives the movement of the supporting rod or the inserting rod, and then indirectly drives the movement of the motor.

[0008] A further technical solution is that a slot is provided on the transverse rod corresponding to the longitudinal rail B, and annular grooves are provided at both ends of the longitudinal rail B. The annular grooves are stuck in the slots, thereby limiting the longitudinal movement of the longitudinal rail.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. The motor adjustment seat bracket of the utility model can adaptably match and install motors with different base hole spacings, and there is no long hole on the motor adjustment seat bracket, so there is no problem of fastening bolts sliding in the long hole. Even if the fastening bolts are slightly loose, the motor will not slide relative to the motor adjustment seat bracket, so it will not affect the normal operation of the oil pumping unit belt.

[0011] 2. The motor of this application has three degrees of freedom after installation: front and back, left and right, and up and down. When mechanical interference occurs during front and back adjustment, this application can also adjust the tension of the belt by adjusting it up and down. Therefore, this application has a wider range of options. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] This embodiment includes two parallel longitudinal guide rails and two transverse rods 5. For the sake of distinction, the two longitudinal guide rails are respectively referred to as longitudinal rails A1 and longitudinal rails B8. The two transverse rods 5 are respectively arranged at the two ends of the longitudinal rails A1 and the longitudinal rails B8, wherein the two ends of the longitudinal rail A1 are respectively fixedly connected to the two transverse rods 5, and the two ends of the longitudinal rail B8 are slidably matched with the transverse rods 5. Two sliding sleeves 7 are respectively slidably installed on the longitudinal rails A1 and the longitudinal rails B8, and each sliding sleeve 7 is respectively fixed with a fastening bolt 9 for connecting to the motor base. The fastening connection between the fastening bolts 9 and different motors is realized through the sliding of the longitudinal rails B8 and the sliding of each sliding sleeve 7.

[0018] The two transverse rods 5 are parallel to each other, and transverse guide rails are slidably mounted inside the two transverse rods 5. For ease of distinction, they are respectively called transverse rails A4 and transverse rails B10. Longitudinal rods 3 are respectively provided at both ends of the transverse rails A4 and B10. The two ends of the transverse rails A4 and B10 are respectively fixedly connected to the longitudinal rods 3. A worm gear reducer B2 is fixedly installed on the longitudinal rod 3 close to the longitudinal rail A1. One end of the worm in the worm gear reducer B2 is connected to the longitudinal rail A1, so that the movement of the worm directly drives the movement of the longitudinal rail A1, and then indirectly drives the left and right movement of the motor.

[0019] One end of the two longitudinal rods 3 is hinged to the pumping unit frame respectively, and a driving gear set is fixedly installed on the pumping unit frame at the other end of the two longitudinal rods 3. The driving gear set includes two mutually meshing gears A15 and two mutually separated gears B16. The gears A15 and B16 are coaxially arranged in a one-to-one correspondence, so that the rotation of the gear A15 drives the rotation of the gear B16. A vertically arranged arc-shaped rack 6 is fixed to the lower side of the transverse rod 5 at this end. Teeth are machined on both sides of the arc-shaped rack 6, and the gears on both sides are respectively meshed with the two gears B16, so that the rotation of the gear B16 drives the arc-shaped rack 6 to move up and down. The up and down movement of the arc-shaped rack 6 directly drives the horizontal rail A4 to move down the mountain, and indirectly drives the up and down movement of the motor.

[0020] A supporting rod 13 and an inserting rod 11 are fixedly connected between a pair of sliding sleeves 7 at corresponding positions on the longitudinal rail A1 and the longitudinal rail B8, and the supporting rod 13 is plugged into the inserting rod 11; a worm gear reducer A12 is fixedly installed on the transverse rod 5, and one end of the worm in the worm gear reducer A12 is connected to the supporting rod 13 or the inserting rod 11, so that the movement of the worm directly drives the movement of the supporting rod 13 or the inserting rod 11, and then indirectly drives the forward and backward movement of the motor.

[0021] The transverse rod 5 corresponding to the longitudinal rail B8 is provided with a slot 14 , and both ends of the longitudinal rail B8 are provided with annular grooves which are stuck in the slot 14 , thereby limiting the longitudinal movement of the longitudinal rail.

[0022] The input shaft ends of the worm gear reducer A and the worm gear reducer B2 are provided with hexagonal cylindrical heads to prevent misoperation, and the outer clearances of the input shafts of the worm gear reducer A and the worm gear reducer B2 are covered with anti-rotation sleeves.

[0023] In summary, after the motor is installed, the present application has three degrees of freedom for adjustment: front-to-back, left-to-right, and up-to-down. Both front-to-back and up-to-down adjustments can adjust the tightness of the motor. However, if mechanical interference occurs in one of these degrees of freedom at the pumping station, adjustment in the other directions will serve as a supplement. The present application achieves a fastening connection between the fastening bolts 9 and different motors through the sliding of the longitudinal rails B8 and the sliding of the various sliding sleeves 7. Therefore, the present application can match the installation of motors with different base hole spacings.
