Description

Technical Field

[0001] The utility model relates to the technical field of motor seats, in particular to an adjustable motor seat. Background Art

[0002] In the field of mechanical transmission, belt drive is widely used in a large number of mechanical equipment due to its simple structure, smooth operation, low noise, ability to mitigate impact, low installation and maintenance requirements, and low cost. Figure 1 As shown, Figure 1 This is a schematic diagram of the matching structure of the motor pulley and the reducer pulley in the prior art; a large number of oil pumping units use a belt drive between the motor and the reducer. However, due to the principle of friction transmission, the belt installation process usually requires ensuring that the motor pulley 100 and the reducer pulley 200 are aligned, and the belt 300 tension is properly adjusted to ensure proper belt operation and a reasonable lifespan. Typically, the tension required for a single belt during operation can reach over 2000N, which is difficult for human labor to withstand, and it is generally not allowed to pry the belt into the pulley groove during installation. Therefore, it is necessary to use appropriate methods to replace and install the belt, ensure pulley alignment, and adjust the belt tension.

[0003] In general, see Figure 2 As shown, Figure 2 This is a top view of the prior art when the motor pulley and the reducer pulley are not aligned; if the motor pulley 100 and the reducer pulley 200 are not aligned, it will cause side wear of the belt 300, affecting the belt life.

[0004] Figure 3 This is a side view of a prior art example of insufficient belt tension between the motor pulley and the reducer pulley. If belt 300 between motor pulley 100 and reducer pulley 200 is insufficiently tensioned, it can cause slippage between the pulleys, generating frictional heat, shortening the belt's lifespan and preventing it from transmitting effectively. Only when the belt tension is properly adjusted can it achieve optimal performance and lifespan.

[0005] The existing motor adjustment method relies on a single set screw at the pulley end, which only allows for one-sided longitudinal adjustment and a narrow adjustment range. If the pulley is misaligned after tensioning, the belt and motor guide rail fixing bolts need to be loosened to adjust the motor position to achieve alignment. This process usually needs to be repeated multiple times to achieve the final alignment and tension state, and it requires the use of lifting equipment, which is inconvenient to operate. Figure 4 As shown, Figure 4 This is a schematic diagram of a state in which the motor 110 is tilted and the pulley is difficult to align when the motor position is adjusted in the prior art. When the belt force is large, the motor is prone to tilt and the pulley is difficult to align.

[0006] The applicant has discovered that the prior art has at least the following technical problems: Therefore, it is difficult to achieve belt alignment and tensioning by adjusting the position of the motor in the motor base in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0043] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0045] See also Figure 1 As shown, Figure 1This is a schematic diagram of the matching structure of the motor pulley and the reducer pulley in the prior art; a large number of oil pumping units use a belt drive between the motor and the reducer. However, due to the principle of friction transmission, the belt installation process usually requires ensuring that the motor pulley 100 and the reducer pulley 200 are aligned, and the belt 300 tension is properly adjusted to ensure proper belt operation and a reasonable lifespan. Typically, the tension required for a single belt during operation can reach over 2000N, which is difficult for human labor to withstand, and it is generally not allowed to pry the belt into the pulley groove during installation. Therefore, it is necessary to use appropriate methods to replace and install the belt, ensure pulley alignment, and adjust the belt tension.

[0046] In general, see Figure 2 As shown, Figure 2 This is a top view of the prior art when the motor pulley and the reducer pulley are not aligned; if the motor pulley 100 and the reducer pulley 200 are not aligned, it will cause side wear of the belt 300, affecting the belt life.

[0047] Figure 3 This is a side view of a prior art example of insufficient belt tension between the motor pulley and the reducer pulley. If belt 300 between motor pulley 100 and reducer pulley 200 is insufficiently tensioned, it can cause slippage between the pulleys, generating frictional heat, shortening the belt's lifespan and preventing it from transmitting effectively. Only when the belt tension is properly adjusted can it achieve optimal performance and lifespan.

[0048] The existing motor adjustment method relies on a single set screw at the pulley end, which only allows for one-sided longitudinal adjustment and a narrow adjustment range. If the pulley is misaligned after tensioning, the belt and motor guide rail fixing bolts need to be loosened to adjust the motor position to achieve alignment. This process usually needs to be repeated multiple times to achieve the final alignment and tension state, and it requires the use of lifting equipment, which is inconvenient to operate. Figure 4 As shown, Figure 4 This is a schematic diagram of a state in which the motor 110 is tilted and the pulley is difficult to align when the motor position is adjusted in the prior art. When the belt force is large, the motor is prone to tilt and the pulley is difficult to align.

[0049] In response to the above problems, an embodiment of the present invention provides an adjustable motor seat, which does not require repeated adjustment of the motor installation position, facilitates alignment of the motor pulley 100 with the reducer pulley 200, and facilitates belt tensioning between the motor pulley and the reducer pulley.

[0050] The following combination Figure 5-Figure 12 The technical solution provided by the utility model is described in more detail.

[0051] The adjustable motor base provided in this embodiment includes a fixed frame 1, a lifting frame 2, a transverse adjustment mechanism and a longitudinal adjustment mechanism, wherein: the lifting frame 2 is rotatably connected to the fixed frame 1 and is arranged to be raised and lowered; the longitudinal adjustment mechanism is located on the lifting frame 2, the longitudinal adjustment mechanism includes a longitudinal movable frame 41, and the transverse adjustment mechanism includes a transverse movable frame 51, and the motor is installed on the transverse movable frame 51; the longitudinal movable frame 41 can drive the transverse movable frame 51 to move along the length direction of the lifting frame 2 to put the belt in a tensioned state; the transverse movable frame 51 can slide on the longitudinal movable frame 41 along the width direction of the lifting frame 2 to align the motor pulley 100 and the reducer pulley 200.

[0052] The width direction of the lifting frame 2 and the length direction of the lifting frame 2 are two directions perpendicular to each other, one of which is the X-axis direction, and the other is the Y-axis direction.

[0053] Among them, the fixed frame 1 is used to be fixed to the equipment to be fixed, the motor 110 is fixed on the transverse moving frame 51, and when the longitudinal moving frame 41 moves along the length direction of the lifting frame 2, it can drive the transverse moving frame 51 and the motor 110 to move synchronously, thereby adjusting the distance between the motor 110 and the reducer pulley 200, thereby adjusting the tension of the belt, and preventing the belt between the motor pulley 100 and the reducer pulley 200 from being insufficiently tensioned, resulting in sliding of the belt and the pulley, frictional heat generation, short belt life and ineffective transmission.

[0054] The transverse movable frame 51 can slide on the longitudinal movable frame 41 along the width direction of the lifting frame 2, so that the motor pulley 100 is aligned with the reducer pulley 200, preventing the motor pulley 100 and the reducer pulley 200 from being misaligned, which will cause the side of the belt to wear and affect the belt life.

[0055] The adjustable motor seat provided in this embodiment adjusts the height of the motor 110 through the lifting frame 2 to achieve rapid tensioning and replacement of the belt 300. The longitudinal movable frame 41 drives the transverse movable frame 51 and the motor 110 to move along the length direction of the lifting frame 2, so that the belt 300 can be tensioned. The transverse movable frame 51 moves along the width direction of the lifting frame 2 on the longitudinal movable frame 41 to adjust the transverse position of the motor 110 to ensure that the motor pulley 100 and the reducer pulley 200 are aligned.

[0056] The adjustable motor seat realizes three-way adjustment of the position of the motor 110, and can realize rapid adjustment of the horizontal position and vertical position of the motor without repeatedly adjusting the motor installation position, which facilitates the alignment of the motor pulley 100 and the reducer pulley 200 and the belt tensioning between the motor pulley 100 and the reducer pulley 200.

[0057] As an alternative embodiment, see Figure 5-Figure 7As shown, the adjustable motor base also includes a lifting drive device 3, wherein: the first end of the lifting frame 2 is rotatably connected to the fixed frame 1, the lower end of the lifting drive device 3 is rotatably connected to the fixed frame 1, the upper end of the lifting drive device 3 is a telescopic end, and the telescopic end is rotatably connected to the second end of the lifting frame 2. In this embodiment, the second end of the lifting frame 2 is arranged away from the reducer pulley 200, and the lifting drive device 3 can drive the second end of the lifting frame 2 to move up and down.

[0058] The lifting drive device 3 in this embodiment can adjust the angle between the lifting frame 2 and the horizontal plane, such as Figure 6 and Figure 7 See Figure 5 As shown, the end of the lifting frame 2 facing the reducer pulley 200 is rotatably connected to the fixed frame 1 through the rotating shaft 21. When the lifting drive device 3 can drive the end of the lifting frame 2 away from the reducer pulley 200 to rise and fall, the lifting frame 2 as a whole rotates around the rotating shaft 21 as the axis.

[0059] The lifting drive device 3 can be a telescopic cylinder, a telescopic electric cylinder, a hydraulic telescopic rod, etc. Figure 7 As shown, when the telescopic end of the lifting drive device 3 is extended, it can drive the end of the lifting frame 2 away from the reducer pulley 200 to rise. The motor is fixed on the horizontal moving frame 51, and the motor rises. At this time, the distance between the motor pulley 100 and the reducer pulley 200 becomes smaller, which makes it convenient to replace the belt.

[0060] After the belt is installed on the pulley, lower the angle adjustment of the lifting frame 2 to make the belt in a tensioned state. If it is not tensioned or too tight, you can also use the longitudinal adjustment mechanism to adjust the longitudinal position of the motor to make the belt reach a suitable tension state.

[0061] As an alternative embodiment, see Figure 8 and Figure 9 As shown, the longitudinal adjustment mechanism also includes a longitudinal adjustment rod 42, a first fixed seat 43, and a first movable seat 44. In this embodiment, the first fixed seat 43 is fixed to the end of the lifting frame 2 facing away from the reducer pulley 200. The first fixed seat 43 is provided with a first threaded hole. The first movable seat 44 is fixed to the longitudinal movable frame 41. The longitudinal adjustment rod 42 passes through the first threaded hole. The end of the longitudinal adjustment rod 42 is rotatably connected to the first movable seat 44. Rotating the longitudinal adjustment rod 42 can push the longitudinal movable frame 41 to move along the length of the lifting frame 2. The lifting frame 2 is provided with a longitudinal guide rail 22, which is arranged along the length of the lifting frame 2. The longitudinal movable frame 41 is slidably connected to the longitudinal guide rail 22. A first bearing seat 45 is fixedly provided on the first movable seat 44. The longitudinal adjustment rod 42 is rotatably connected to the first bearing seat 45 to ensure that the longitudinal adjustment rod 42 can rotate flexibly.

[0062] Among them, the longitudinal adjustment rod 42 is provided with an external thread. Since the longitudinal adjustment rod 42 is threadedly connected to the first threaded hole, and the end of the longitudinal adjustment rod 42 is rotatably connected to the first bearing seat 45, when the longitudinal adjustment rod 42 is screwed, the longitudinal adjustment rod 42 pushes the longitudinal movable frame 41 to slide along the longitudinal guide rail 22, and the longitudinal movable frame 41 moves along the length direction of the lifting frame 2. When the longitudinal adjustment rod 42 stops being screwed, the position of the longitudinal movable frame 41 no longer changes, that is, the position of the longitudinal movable frame 41 is determined.

[0063] As an alternative embodiment, see Figure 10 and Figure 11 、 Figure 12 As shown, the lateral adjustment mechanism also includes a lateral adjustment rod 52, a second fixed seat 53, and a second movable seat 54. The second fixed seat 53 is fixed to the side of the longitudinal movable frame 41 and is provided with a second threaded hole. The second movable seat 54 is fixed to the lateral movable frame 51. The lateral adjustment rod 52 passes through the second threaded hole, and the end of the lateral adjustment rod 52 is rotatably connected to the second movable seat 54. Rotating the lateral adjustment rod 52 can push the lateral movable frame 51 along the width direction of the lifting frame 2. The longitudinal movable frame 41 is provided with a lateral guide rail, which is arranged along the width direction of the lifting frame 2. The lateral movable frame 51 is slidably connected to the lateral guide rail. A second bearing seat 55 is fixedly provided on the second movable seat 54. The lateral adjustment rod 52 is rotatably connected to the second bearing seat 55, ensuring that the lateral adjustment rod 52 can rotate flexibly.

[0064] Among them, the lateral adjustment rod 52 is provided with an external thread. Since the lateral adjustment rod 52 is threadedly connected to the second threaded hole, and the end of the lateral adjustment rod 52 is rotatably connected to the second bearing seat 55, when the lateral adjustment rod 52 is screwed, the lateral adjustment rod 52 pushes the lateral moving frame 51 to slide along the lateral guide rail, and the lateral moving frame 51 moves along the width direction of the lifting frame 2. When the lateral adjustment rod 52 stops being screwed, the position of the lateral moving frame 51 no longer changes, that is, the position of the lateral moving frame 51 is determined.

[0065] See also Figure 12 As shown, the second fixed seat 53 is provided with a lubrication hole 9 for lubricating the movable parts. Similarly, the first fixed seat 43 can also be provided with a lubrication hole 9. The lubrication hole 9 mainly lubricates the external thread of the corresponding adjustment rod. The first bearing seat 45 and the second bearing seat 55 are greased and sealed during assembly.

[0066] See also Figure 12 As shown, the locking nut 56 that is threadedly connected on the lateral adjustment rod 52 is used to lock the lateral adjustment rod 52 after being adjusted to the appropriate position, limit its rotation, and improve the stability of the structure. Of course, a corresponding locking nut can also be set on the longitudinal adjustment rod to lock the longitudinal adjustment rod.

[0067] As an alternative embodiment, see Figure 10 and Figure 11 As shown, the transverse movable frame 51 is provided with at least two mounting parts (mounting guide rails 6) for fixing the motor, the mounting parts (mounting guide rails 6) are arranged at intervals along the length direction of the lifting frame 2, and the distance between the two mounting parts (mounting guide rails 6) is adjustable.

[0068] The distance between the two mounting parts can be adjusted to flexibly adapt to motors of different sizes, with a wide range of applications.

[0069] As an alternative embodiment, see Figure 10 and Figure 11 As shown, the mounting portion includes a mounting rail 6 , which extends along the width direction of the lifting frame 2 .

[0070] The motor can slide to a predetermined position along the mounting rail 6 and then be locked in this position to complete the adjustment of the motor's initial position. The above structure can also achieve lateral adjustment of the motor position, that is, adjust the position of the motor in the width direction of the lifting frame 2.

[0071] In this embodiment, when the motor is installed, the installation guide rail 6 can be used as the primary adjustment of the motor's lateral position, and rotating the lateral adjustment rod 52 can be used as the secondary adjustment of the motor's lateral position.

[0072] As an alternative embodiment, see Figure 10 and Figure 11 As shown, the mounting portion is fixed on the adjusting block 7, and an adjusting hole 71 is provided on the adjusting block 7. The adjusting hole 71 is a long strip hole and extends along the length direction of the lifting frame 2. The locking member 8 passes through the adjusting hole 71 to lock the adjusting block 7 on the transverse moving frame 51, and when the locking member 8 is fixed at different positions of the adjusting hole 71, the distance between the two mounting portions can be adjusted.

[0073] The locking member 8 may be a locking bolt and nut assembly. When the locking member 8 is loosened, the locking member 8 and the adjustment hole 71 can slide relative to each other to adjust the distance between the two mounting rails. After the distance between the two mounting rails is adjusted, the locking member 8 can be tightened to lock the mounting rails to the transverse movable frame 51.

[0074] As an alternative embodiment, see Figure 6 As shown, the fixing frame 1 includes a horizontal seat 11 and a support rod 12. One end of the horizontal seat 11 is fixed to the device to be fixed. The support rod 12 is arranged at an angle. The bottom end of the support rod 12 is fixed to the device to be fixed. The high end of the support rod 12 is fixedly connected to the fixing frame 1.

[0075] The horizontal seat 11, the support rod 12 and the equipment to be fixed can form a stable triangular structure, thereby improving the stability of the structure and ensuring stable operation of the motor.

[0076] Generally, during use, the lifting drive device 3 is operated to position the lifting frame 2 in a horizontal position. The motor 110 is then mounted on the mounting rail 6. The lateral position of the motor 110 is adjusted to ensure alignment between the motor pulley 100 and the reducer pulley 200. The longitudinal adjustment rod 42 is pre-adjusted according to the belt length to position the motor in the appropriate position. The lifting drive device 3 is then used to raise the end of the lifting frame 2 facing the reducer pulley 200. This reduces the distance between the motor pulley 100 and the reducer pulley 200, allowing for easy insertion of the belt. After the belt 300 is mounted on the pulley, the end of the lifting frame 2 facing the reducer pulley 200 is lowered to tension the belt 300. If the belt 300 is not tensioned or is too tight, the longitudinal adjustment rod 42 can be used to adjust the longitudinal position of the motor to achieve the appropriate tension on the belt 300.

[0077] When replacing the belt, generally, it is only necessary to control the lifting drive device 3 to raise the motor. At this time, the distance between the motor pulley 100 and the reducer pulley 200 becomes smaller, and the belt can be replaced.

[0078] Compared with the traditional single top screw adjustment method, this mechanism has the following advantages:

[0079] 1. It is adjustable in three directions, which can realize the rapid adjustment of the motor's lateral position without the need to repeatedly adjust the motor installation position.

[0080] 2. The motor installation operation avoids repeated adjustments.

[0081] 3. The belt can be quickly tightened and replaced by adjusting the lifting frame 2.

[0082] 4. It can be applied to situations where the belt tension is large (the advantages are more obvious under conditions of large motors and multiple belts).
