Description

Technical Field

[0001] This invention belongs to the technical field of oil extraction equipment, and in particular relates to a flexible motor base with adaptive belt tension and a method for adapting it. Background Technology

[0002] In industrial production, an oil pumping unit is a machine used to extract oil, commonly known as a nodding donkey. It is mainly used to lift oil from underground oil layers to the surface. Its working principle is that the rotation of the motor is transmitted to the rocker arm through a gearbox and other transmission devices. The rocker arm moves up and down reciprocatingly, which drives the piston of the oil pump downhole to move reciprocally through the sucker rod. The electric motor is the main power source, and the motor base is a key component connecting the motor and the working equipment. Its performance directly affects the stability and reliability of the entire transmission system.

[0003] The base structure used to mount the electric motor has a significant impact on the stable operation of the motor and the stable transmission of the belt. Due to the large weight of the motor, the tension of the belt is difficult to adjust, and after a certain period of operation, natural stretching will occur, leading to insufficient belt transmission. Furthermore, under alternating resistance, since the belt tension is relatively fixed, the motor cannot automatically adjust, causing the entire transmission force to be concentrated on the belt, accelerating belt wear and even breakage. Therefore, it is necessary to provide a flexible motor base and adaptation method with adaptive belt tension. This method uses elastic support and the motor's own weight to tension the belt, ensuring stable transmission. At the same time, under the action of elasticity, the belt can automatically adjust its tension according to the required size, preventing excessive wear and breakage. Summary of the Invention

[0013] Preferably, both sides of the inner cavity of the spherical sleeve are fixedly connected to limit blocks, and both sides of the threaded sleeve are provided with limit grooves that are adapted to the limit blocks.

[0014] An adaptive method for a flexible motor base with self-adaptive belt tensioning, comprising the following steps:

[0015] Step 1: When using this flexible motor base, first move the base frame to the designated position. Then, place the motor on top of the mounting base, aligning the second threaded seat with the motor's mounting hole. Next, rotate the first threaded adjusting rod. During rotation, the first threaded adjusting rod pushes the first threaded seat forward through its surface thread, allowing the first threaded seat to slide within the rectangular groove, aligning it with the mounting hole on the left side of the motor. Then, insert bolts into the cavities of the first and second threaded seats to install the mounting base and displacement plate. Next, drive the second threaded adjusting rod with a pneumatic wrench. During rotation, the second threaded adjusting rod, through the cooperation of its surface thread and arc-shaped groove, pushes the motor bracket back and forth. Simultaneously, the arc-groove ear plate slides on the surface of the threaded column. Once the position is determined, tighten the second nut onto the surface of the arc-groove ear plate to fix the motor and motor bracket, ensuring the motor is stably mounted on top of the displacement plate.

[0016] Step 2: The user then rotates the handle, which drives the threaded push rod to rotate. As the threaded push rod rotates, it pushes the moving seat forward through its surface threads. This causes the moving seat to move the two extrusion rollers to the left, making the surfaces of the extrusion rollers fit tightly against the inclined surface of the wedge block and pushing the wedge block forward. This causes the tilting table to rotate around its connection point with the bearing seat, thereby raising the motor and bringing it closer to the force plate of the pumping unit reducer. Then, the belt is fitted onto the output plate of the motor and the force plate of the pumping unit reducer.

[0017] During the rotation of the handle, the transmission rod rotates due to the meshing of the drive gear and the force gear. The transmission rod, in turn, drives the drive rod to rotate through the meshing of two bevel gears. The drive rod then rotates via a worm gear, which in turn drives the rotating column through a meshing worm wheel. This rotation of the rotating column, in turn, drives the threaded lifting rod to rotate via a universal coupling. This allows the threaded lifting rod to rotate within the inner cavity of the threaded sleeve, thus expanding the relative length of the threaded lifting rod and the threaded sleeve as the tilting table moves upwards. This prevents compression of the spring during the rotation of the tilting table, making it easier for the user to lift the tilting table.

[0018] Step 3: After the belt is assembled, the user rotates the handle in the opposite direction, causing the threaded push rod to rotate in the opposite direction. This causes the moving seat and the pressing wheel to reset to the right, releasing the lifting of the tilting table. At the same time, under the transmission action of the drive gear, transmission rod, and force gear, the bevel gear rotates in the opposite direction, causing the drive rod, worm, and worm wheel to rotate in the opposite direction. This causes the universal coupling and the threaded lifting rod to rotate in the opposite direction, allowing the threaded lifting rod to re-enter the inner cavity of the threaded sleeve. After the bottom end of the threaded sleeve completely reaches the bottom of the surface of the threaded lifting rod, the downward movement of the threaded sleeve compresses the spring, giving the spring sufficient elasticity to push the spring, threaded sleeve, and tilting table downwards. At the same time, under the gravity of the motor, the tilting table can also be pressed downwards. At this time, the belt is in a taut state.

[0019] During the operation of the electric motor, the belt is tightened by the gravity generated by the motor and the downward elastic force generated by the spring. This allows the motor to be stably transmitted through the force-bearing plate, the belt, and the force-bearing plate of the pumping unit reducer. When the pumping unit reducer is subjected to vibration, the belt force can pull the motor and the tilting table upward to a certain displacement. The spherical sleeve slides on the surface of the threaded sleeve, and at the same time, the spring is compressed to a certain extent, releasing a certain buffer length for the belt and preventing the belt from being overstretched, causing wear and breakage.

[0020] The beneficial effects of the present invention are as follows: By setting the installation components, the present invention stably installs the motor on the top of the tilting table. Then, with the cooperation of the elastic components, the tilting table and the motor are pushed downward with elastic force. At the same time, with the cooperation of the handle, transmission components and lifting components, the tilting table can be raised to facilitate the user to put on the belt, thereby achieving the purpose of preventing the belt from breaking or wearing due to excessive stress and facilitating belt replacement.

The arc-shaped threaded groove 126 is threadedly connected to the surface of the second threaded adjustment rod 125.

[0040] An adaptive method for a flexible motor base with self-adaptive belt tensioning, comprising the following steps:

[0041] Step 1: When using this flexible motor base, first move the base frame 1 to the designated position. Then, the user places the motor 4 on top of the mounting base 51, aligning the second threaded seat 55 with the mounting hole of the motor 4. Next, the user rotates the first threaded adjusting rod 54. During rotation, the first threaded adjusting rod 54 pushes the first threaded seat 53 forward through its surface threads, allowing the first threaded seat 53 to slide within the rectangular groove 52, aligning it with the mounting hole on the left side of the motor 4. Then, the user inserts the bolt 56 through the first threaded seat 53 and... The second threaded seat 55 is installed in the inner cavity, allowing the mounting seat 51 and the displacement plate 121 to be installed. Then, the user drives the second threaded adjusting rod 125 with a pneumatic wrench. During the rotation of the second threaded adjusting rod 125, the motor bracket 122 is pushed back and forth through the cooperation of its surface thread and arc-shaped threaded groove 126. At the same time, the arc-shaped groove ear plate 123 slides on the surface of the threaded post 124. After the position is determined, the user tightens the second nut 127 and presses it onto the surface of the arc-shaped groove ear plate 123 to fix the motor 4 and the motor bracket 122, so that the motor 4 is stably installed on the top of the displacement plate 121.

[0042] Step 2: The user then rotates the handle 7. During the rotation of the handle 7, the threaded push rod 95 rotates. During the rotation of the threaded push rod 95, the moving seat 92 is pushed forward through its surface threads. This causes the moving seat 92 to drive the two extrusion rollers 93 to move to the left. This causes the surface of the extrusion rollers 93 to fit tightly against the inclined surface of the wedge block 94 and push the wedge block 94 forward. This causes the tilting table 2 to rotate around its connection point with the bearing seat 3. This causes the motor 4 to rise and move closer to the force plate of the pumping unit reducer. Then, the belt is fitted onto the output plate of the motor 4 and the force plate of the pumping unit reducer.

[0043] During the rotation of handle 7, the transmission rod 84 rotates due to the meshing transmission of drive gear 85 and force gear 86. During the rotation of transmission rod 84, the drive rod 81 rotates through the meshing transmission of two bevel gears 87. During the rotation of drive rod 81, the worm gear 82 rotates through the worm wheel 83 meshing with it, which drives the rotating column 61 to rotate. During the rotation of rotating column 61, the threaded lifting rod 63 rotates through universal coupling 62, so that the threaded lifting rod 63 can rotate in the inner cavity of threaded sleeve 64. As a result, during the upward movement of the tilting table 2, the relative length of threaded lifting rod 63 and threaded sleeve 64 is expanded, thereby preventing the spring 67 from being compressed during the rotation of tilting table 2, thus making it easier for the user to lift tilting table 2.

[0044] Step 3: After the belt is assembled, the user rotates the handle 7 in the opposite direction, causing the threaded push rod 95 to rotate in the opposite direction. This causes the moving seat 92 and the pressing wheel 93 to reset to the right, releasing the lifting of the tilting table 2. At the same time, under the transmission action of the drive gear 85, the transmission rod 84 and the force-bearing gear 86, the bevel gear 87 rotates in the opposite direction, causing the drive rod 81, the worm gear 82 and the worm wheel 83 to rotate in the opposite direction. This causes the universal coupling 62 and the threaded lifting rod 63 to rotate in the opposite direction, so that the threaded lifting rod 63 re-enters the inner cavity of the threaded sleeve 64. After the bottom end of the threaded sleeve 64 completely reaches the bottom of the surface of the threaded lifting rod 63, the downward movement of the threaded sleeve 64 compresses the spring 67, so that the spring 67 has sufficient elasticity to push the spring 67, the threaded sleeve 64 and the tilting table 2 downward with elastic force. At the same time, under the gravity of the motor 4, the tilting table 2 can also be pressed downward. At this time, the belt is in a taut state.

[0045] During the operation of the motor 4, the belt is tightened by the gravity generated by the motor 4 and the downward elastic force generated by the spring 67, so that the motor 4 can be stably transmitted through the force plate, the belt and the force plate of the pumping unit reducer. When the pumping unit reducer is vibrated, the belt can pull the motor 4 and the tilting table 2 upward to a certain displacement. The spherical sleeve 65 slides on the surface of the threaded sleeve 64, and at the same time, the spring 67 is compressed to a certain extent, releasing a certain buffer length for the belt and preventing the belt from being overstretched, causing wear and breakage.

[0046] In summary, the adaptive belt tension and relaxation flexible motor base and adaptation method, through the setting of the mounting component 5, stably mount the motor 4 on the top of the tilting platform 2. Subsequently, with the cooperation of the elastic component 6, the tilting platform 2 and the motor 4 are pushed downward with elastic force. At the same time, with the cooperation of the handle 7, the transmission component 8 and the lifting component 9, the tilting platform 2 can be raised to facilitate the user to put on the belt, thereby achieving the purpose of preventing the belt from breaking due to excessive stress and wear, and facilitating belt replacement.

[0047] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.

9. A method for adapting a flexible motor base with adaptive belt tension, applied to the flexible motor base with adaptive belt tension as described in claim 8, characterized in that... The method and steps are as follows: Step 1: When using this flexible motor base, first move the base frame (1) to the designated position. Then, the user places the motor (4) on top of the mounting base (51), so that the second threaded seat (55) is aligned with the mounting hole of the motor (4). Then, the user rotates the first threaded adjusting rod (54). During the rotation, the first threaded adjusting rod (54) pushes the first threaded seat (53) through its surface thread, so that the first threaded seat (53) slides in the inner cavity of the rectangular slide groove (52), so that the first threaded seat (53) is aligned with the mounting hole on the left side of the motor (4). Then, the user inserts the bolt (56) through the first threaded seat (53) and the second threaded seat (55). In the inner cavity of the second threaded seat (55), the mounting seat (51) and the displacement plate (121) are installed. Then, the user drives the second threaded adjusting rod (125) with a pneumatic wrench. During the rotation of the second threaded adjusting rod (125), the motor bracket (122) is pushed back and forth by the cooperation of its surface thread and arc-shaped thread groove (126). At the same time, the arc groove ear plate (123) slides on the surface of the threaded column (124). After the position is determined, the user tightens the second nut (127) and presses it onto the surface of the arc groove ear plate (123) to fix the motor (4) and the motor bracket (122), so that the motor (4) is stably installed on the top of the displacement plate (121). Step 2: The user then rotates the handle (7). During the rotation of the handle (7), the threaded push rod (95) rotates. During the rotation of the threaded push rod (95), the moving seat (92) is pushed through its surface thread, causing the moving seat (92) to drive the two extrusion wheels (93) to move to the left. This causes the surface of the extrusion wheel (93) to fit tightly against the inclined surface of the wedge block (94) and pushes the wedge block (94). This causes the tilting table (2) to rotate with its connection position with the bearing seat (3) as the rotation center, thereby causing the motor (4) to rise up and move closer to the force plate of the pump reducer. Then, the belt is put on the output plate of the motor (4) and the force plate of the pump reducer. During the rotation of the handle (7), the transmission rod (84) rotates due to the meshing transmission of the drive gear (85) and the force gear (86). During the rotation of the transmission rod (84), the drive rod (81) rotates through the meshing transmission of the two bevel gears (87). During the rotation of the drive rod (81), the drive rod (81) rotates through the worm gear (82). The worm gear (82) rotates through the worm wheel (83) meshing with it, which drives the rotating column (61) to rotate. During the rotation of the rotating column (61), the threaded lifting rod (63) rotates through the universal coupling (62), so that the threaded lifting rod (63) can rotate in the inner cavity of the threaded sleeve (64). As a result, during the upward movement of the tilting table (2), the relative length of the threaded lifting rod (63) and the threaded sleeve (64) is expanded, thereby preventing the tilting table (2) from compressing the spring (67) during the rotation, thus making it easier for the user to lift the tilting table (2). Step 3: After the belt assembly is completed, the user rotates the handle (7) in the opposite direction, causing the threaded push rod (95) to rotate in the opposite direction, thereby causing the moving seat (92) and the pressing wheel (93) to reset to the right, releasing the lifting of the tilting table (2). At the same time, under the transmission action of the drive gear (85), transmission rod (84) and force-bearing gear (86), the bevel gear (87) rotates in the opposite direction, causing the drive rod (81), worm (82) and worm wheel (83) to rotate in the opposite direction, thereby causing the universal joint (62) and the threaded lifting rod (63) to rotate in the opposite direction. The reverse rotation causes the threaded lifting rod (63) to re-enter the inner cavity of the threaded sleeve (64) until the bottom end of the threaded sleeve (64) completely reaches the bottom of the surface of the threaded lifting rod (63). The downward movement of the threaded sleeve (64) compresses the spring (67), so that the spring (67) generates sufficient elasticity to push the spring (67), the threaded sleeve (64) and the tilting table (2) downward. At the same time, under the gravity of the motor (4), the tilting table (2) can also be pressed downward. At this time, the belt is in a taut state. During the operation of the motor (4), the belt is tightened by the gravity generated by the motor (4) and the downward elastic force generated by the spring (67), so that the motor (4) can be stably transmitted through the force plate, the belt and the force plate of the pumping unit reducer. When the pumping unit reducer is vibrated, the belt can pull the motor (4) and the tilting table (2) upward to a certain displacement. The spherical sleeve (65) slides on the surface of the threaded sleeve (64), and at the same time, the spring (67) is compressed to a certain extent, releasing a certain buffer length for the belt, preventing the belt from being overstretched and causing wear and breakage.
