Description

Technical Field

[0001] The invention belongs to the technical field of oil production equipment, and in particular relates to a flexible motor base with adaptive belt tension and relaxation and an adaptation method. Background Art

[0002] In industrial production, an oil pump is a machine for extracting oil, commonly known as a kowtow machine. It is mainly used to lift oil from underground oil layers to the ground. Its working principle is to transmit power to the rocker arm through the rotation of the motor through transmission devices such as the reduction gearbox. The rocker arm reciprocates up and down, and the pump rod drives the downhole oil pump piston to reciprocate. The electric motor is its 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 for installing the motor has a great influence on the stable operation of the motor and the stable transmission of the belt. Due to the large deadweight of the motor, the tightness of the belt is inconvenient to adjust, and after running for a certain period of time, it will naturally stretch, resulting in insufficient belt transmission. In the case of alternating resistance, since the tension of the belt is relatively fixed, the motor cannot automatically adjust, resulting in the full pressure of the transmission force on the belt, accelerating the wear of the belt or even breaking it. For this reason, it is necessary to provide a flexible motor base with adaptive belt tension and an adaptation method, which adopts the method of elastic support and the deadweight of the motor to tighten the belt for stable transmission. At the same time, under the action of elastic force, the belt can automatically adjust the tightness according to the adaptation size to prevent excessive wear and breakage. Summary of the invention

[0004] The purpose of the present invention is to provide a flexible motor base with adaptive belt tensioning and an adaptation method, which adopts elastic support and the motor's own weight to tighten the belt to ensure stable transmission.

[0014] An adaptation method for a flexible motor base with adaptive belt tensioning, the method steps are as follows: The first threaded adjustment rod is used to push the first threaded adjustment rod toward the first threaded seat, and the second threaded adjustment rod is used to push the first threaded seat toward the mounting hole on the left side of the motor. The user then inserts the bolt into the inner cavity of the first threaded seat and the second threaded seat to install the mounting seat and the displacement plate. The user then drives the second threaded adjustment rod with a pneumatic wrench. The second threaded adjustment rod is used to push the motor bracket forward and backward through the cooperation of its surface thread and the arc groove during the rotation, and the arc groove ear plate slides on the surface of the threaded column. After the position is determined, the user tightens the second nut and presses it onto the surface of the arc groove ear plate to fix the motor and the motor bracket, so that the motor is stably mounted on the top of the displacement plate. Step 2: The user then rotates the handle, and the handle drives the threaded push rod to rotate during the rotation process. The threaded push rod pushes the moving seat through its surface thread during the rotation process, so that the moving seat drives the two extrusion wheels to move to the left, so that the surface of the extrusion wheel fits tightly with the inclined surface of the wedge block, and pushes the wedge block, so that the turning table rotates with its connection position with the bearing seat as the rotation center, so that the motor can rise upward, so that the motor is close to the force plate of the oil pumping unit reducer, and then the belt is set on the output plate of the motor and the surface of the force plate of the oil pumping unit reducer; During the rotation of the handle, the transmission rod rotates due to the meshing transmission of the driving gear and the force-bearing gear. During the rotation of the transmission rod, the driving rod is driven to rotate by the meshing transmission of the two bevel gears. During the rotation of the driving rod, the worm is rotated. The worm drives the rotating column to rotate through the worm gear meshed with the worm. During the rotation of the rotating column, the threaded lifting rod is driven to rotate through the universal joint, so that the threaded lifting rod can rotate in the inner cavity of the threaded sleeve. As a result, during the upward movement of the turning platform, the relative length of the threaded lifting rod and the threaded sleeve is expanded, thereby preventing the turning platform from compressing the spring during the rotation process, so that it is convenient for the user to lift the turning platform. Step 3. After the belt is assembled, the user rotates the handle in the opposite direction, so that the threaded push rod rotates in the opposite direction, and then the moving seat and the extrusion wheel are reset to the right, and the lifting of the turning table is released. At the same time, under the transmission action of the driving gear, the transmission rod and the force gear, the bevel gear rotates in the opposite direction, so that the driving rod, the worm and the worm wheel rotate in the opposite direction, and then the universal joint and the threaded lifting rod rotate in the opposite direction, so that the threaded lifting rod is re-entered into the inner cavity of the threaded sleeve until 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, so that the spring has sufficient elasticity to push the spring, the threaded sleeve and the turning table downward. At the same time, under the gravity of the motor, the turning table can also be pressed downward. At this time, the belt is in a tensioned state; During the operation of the motor, the belt is tightened under the action of the gravity generated by the motor and the downward elastic force generated by the spring, so that the motor can be stably transmitted through the force plate, belt and force plate of the oil pump reducer. When the oil pump reducer is vibrated, the force on the belt can pull the motor and the turning table upward to a certain displacement, and 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 to prevent excessive stretching of the belt from causing wear and breakage.

[0015] The beneficial effects of the present invention are as follows: the present invention stably installs the motor on the top of the turning table through the arrangement of the installation component, and then, with the cooperation of the elastic component, the turning table and the motor are pushed downward by the elastic force. At the same time, with the cooperation of the handle, the transmission component and the lifting component, the turning table can be lifted to facilitate the user to put on the belt, thereby achieving the purpose of preventing the belt from being excessively stressed and broken, worn, and facilitating the replacement of the belt.

[0025] An adaptation method for a flexible motor base with adaptive belt tensioning, the method steps are as follows: Step 1: When using the flexible motor base, first move the base frame 1 to the specified position, then place the motor 4 on the top of the mounting seat 51, so that the second threaded seat 55 can be aligned with the mounting hole of the motor 4, then the user rotates the first threaded adjustment rod 54, and the first threaded adjustment rod 54 pushes the first threaded seat 53 through its surface thread during the rotation, so that the first threaded seat 53 can slide in the inner cavity of the rectangular slide groove 52, so that the first threaded seat 53 can be aligned with the mounting hole on the left side of the motor 4, then the user passes the bolt 56 through the first threaded seat 53 and The mounting seat 51 and the displacement plate 121 are installed in the inner cavity of the second threaded seat 55, and then the user drives the second threaded adjustment rod 125 with a pneumatic wrench. The second threaded adjustment rod 125 pushes the motor bracket 122 forward and backward through the cooperation of its surface thread and the arc-shaped screw groove 126 during the rotation process. 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 on 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, which drives the threaded push rod 95 to rotate during the rotation process. The threaded push rod 95 pushes the moving seat 92 through its surface threads during the rotation process, so that the moving seat 92 drives the two extrusion wheels 93 to move to the left, so that the surface of the extrusion wheel 93 is closely fitted with the inclined surface of the wedge block 94, and the wedge block 94 is pushed, so that the turning table 2 rotates with its connection position with the bearing seat 3 as the rotation center, thereby allowing the motor 4 to rise upward, so that the motor 4 is close to the force plate of the oil pumping unit reducer, and then the belt is set on the output plate of the motor 4 and the surface of the force plate of the oil pumping unit reducer; During the rotation of the handle 7, the transmission rod 84 rotates due to the meshing transmission of the driving gear 85 and the force-bearing gear 86. During the rotation, the transmission rod 84 drives the driving rod 81 to rotate through the meshing transmission of the two bevel gears 87. During the rotation, the driving rod 81 rotates through the worm 82. The worm 82 drives the rotating column 61 to rotate through the worm wheel 83 meshing therewith. During the rotation of the rotating column 61, the threaded lifting rod 63 is driven to rotate through the universal coupling 62, so that the threaded lifting rod 63 can rotate in the inner cavity of the threaded sleeve 64, and then the relative length of the threaded lifting rod 63 and the threaded sleeve 64 is expanded during the upward movement of the turning platform 2, thereby preventing the turning platform 2 from compressing the spring 67 during the rotation, so that it is convenient for the user to lift the turning platform 2. Step 3, after the belt is assembled, the user rotates the handle 7 in the opposite direction, so that the threaded push rod 95 rotates in the opposite direction, thereby causing the moving seat 92 and the extrusion wheel 93 to reset to the right side, releasing the lifting of the turning table 2. At the same time, under the transmission action of the driving gear 85, the transmission rod 84 and the force-bearing gear 86, the bevel gear 87 rotates in the opposite direction, causing the driving rod 81, the worm 82 and the 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, so that the threaded lifting rod 63 is re-entered into 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 has sufficient elasticity to push the spring 67, the threaded sleeve 64 and the turning table 2 downward. At the same time, under the gravity of the motor 4, the turning table 2 can also be pressed downward. At this time, the belt is in a tensioned state; During the operation of the motor 4, the belt is tightened under the action of 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 oil pump reducer. When the oil pump reducer is vibrated, the belt force can pull the motor 4 and the turning table 2 to move upward to a certain extent, and 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, thereby releasing a certain buffer length for the belt to prevent excessive stretching of the belt from causing wear and breakage.

[0026] In summary: the flexible motor base with adaptive belt tension and the adaptation method, through the setting of the mounting component 5, stably mounts the motor 4 on the top of the turning table 2, and then with the cooperation of the elastic component 6, the turning table 2 and the motor 4 are pushed downward by the elastic force. At the same time, with the cooperation of the handle 7, the transmission component 8 and the lifting component 9, the turning table 2 can be lifted to facilitate the user to put on the belt, thereby achieving the purpose of preventing the belt from being excessively stressed and broken, worn, and facilitating the replacement of the belt.

[0027] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the invention to achieve the purpose of the invention.

10. An adaptation method for a flexible motor base with adaptive belt tension, which is applied to the flexible motor base with adaptive belt tension as claimed in claim 9, characterized in that: The method steps are as follows: Step 1: When the flexible motor base is used, the base frame (1) is first moved to a designated position, and then the user places the motor (4) on the top of the mounting seat (51) so that the second threaded seat (55) can be aligned with the mounting hole of the motor (4). Then the user rotates the first threaded adjustment rod (54). During the rotation, the first threaded adjustment rod (54) pushes the first threaded seat (53) through its surface thread, so that the first threaded seat (53) can slide in the inner cavity of the rectangular slide groove (52), so that the first threaded seat (53) can be aligned with the mounting hole on the left side of the motor (4). Then the user passes the bolt (56) through the first threaded seat (53) and the second threaded seat (55). The mounting seat (51) and the displacement plate (121) are mounted in the inner cavity of the second threaded seat (55), and then the user drives the second threaded adjustment rod (125) through a pneumatic wrench. During the rotation process, the second threaded adjustment rod (125) advances the motor bracket (122) forward and backward through the cooperation of the surface thread and the arc-shaped screw 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 on 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 mounted on the top of the displacement plate (121); Step 2: The user then rotates the handle (7), and the handle (7) drives the threaded push rod (95) to rotate during the rotation process. The threaded push rod (95) pushes the movable seat (92) through the thread on its surface during the rotation process, so that the movable seat (92) drives the two extrusion wheels (93) to move to the left, so that the surface of the extrusion wheel (93) is tightly fitted with the inclined surface of the wedge block (94), and the wedge block (94) is pushed, so that the turning table (2) rotates with the connection position between it and the bearing seat (3) as the rotation center, thereby allowing the motor (4) to rise upward, so that the motor (4) is close to the force plate of the oil pumping unit reducer, and then the belt is sleeved on the output plate of the motor (4) and the surface of the force plate of the oil pumping unit reducer; During the rotation of the handle (7), the transmission rod (84) rotates due to the meshing transmission of the driving gear (85) and the force-bearing gear (86). During the rotation of the transmission rod (84), the driving rod (81) is driven to rotate by the meshing transmission of the two bevel gears (87). During the rotation of the driving rod (81), the worm (82) drives the rotating column (61) to rotate through the worm gear (83) meshing therewith. During the rotation of the rotating column (61), the threaded lifting rod (63) is driven to rotate through the universal joint (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 flip table (2), the relative length of the threaded lifting rod (63) and the threaded sleeve (64) is increased, thereby preventing the flip table (2) from compressing the spring (67) during the rotation, thereby facilitating the user to lift the flip table (2); 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, thereby causing the moving seat (92) and the extrusion wheel (93) to return to the right side, thereby releasing the lifting of the turning table (2). At the same time, under the transmission action of the driving gear (85), the transmission rod (84) and the force gear (86), the bevel gear (87) rotates in the opposite direction, causing the driving rod (81), the worm (82) and the 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. ) is rotated in the opposite direction, so that the threaded lifting rod (63) is re-entered into 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), and 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 turning table (2) downward. At the same time, under the gravity of the motor (4), the turning table (2) can also be pressed downward, and the belt is in a tensioned state at this time; During the operation of the motor (4), the belt is tightened under the action of 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 driven through the force plate, the belt and the force plate of the pumping unit reducer. When the pumping unit reducer is vibrated, the force on the belt can pull the motor (4) and the turning table (2) upward to a certain displacement, and the spherical sleeve (65) slides on the surface of the threaded sleeve (64), while causing the spring (67) to be compressed to a certain extent, thereby releasing a certain buffer length for the belt, thereby preventing the belt from being overstretched and causing wear and breakage.
