Description

Technical Field

[0001] The utility model belongs to the technical field of motor relative position adjustment devices, and in particular relates to an adjustable motor base. Background Art

[0002] In oil production operations, the continuous operation of the pumping unit depends on the motor to provide driving power. The motor and the pumping unit are mostly driven by belts. Due to the force, elongation and wear of the belt, it will become loose, which seriously affects the power transmission and mechanical efficiency. In order to adjust the tightness of the belt or replace the belt, the transmission belt is usually replaced or the tightness is adjusted by adjusting the mobile motor. In production practice, the motor is usually fixed to the motor base by multiple bolts. Its installation position is generally narrow, which is not conducive to the motor position adjustment operation. In the operation process, multiple people are required to cooperate with the operation at the same time, and use a variety of tools such as crowbars and wrenches to adjust the motor position. This process is time-consuming and labor-intensive, with high labor intensity, low safety factor, and low work efficiency. At the same time, when using a crowbar to pry the motor, the motor angle adjustment phenomenon is easy to occur, resulting in the belt "four points and one line" unqualified, and it is more likely to cause uneven force on the belt, thereby accelerating the wear of the belt and reducing the service life of the belt. As an improvement, the motor base is set as a movable structure, and the motor is generally adjusted by a top screw. Although the motor can move in parallel, the labor intensity is still high and the operation process is cumbersome. At the same time, due to the narrow operating position, it is easy to cause violations in daily operations, causing unnecessary safety hazards.

[0003] As an improvement, a Chinese patent with authorization announcement number CN217183115U and authorization announcement date August 12, 2022 discloses a pumping unit rapid moving motor slide rail device, including a first support, a second support, a slide rail, a motor base and a reducer base, at least two slide rails are arranged in parallel and spaced apart between the first support and the second support to fixedly connect the first support and the second support, and the motor base and the reducer base can be slidably mounted on the slide rail; the second support is rotatably equipped with a hollow lead screw and an inner lead screw extending in the front and rear directions, and the inner lead screw is coaxially inserted in the hollow lead screw; a worm gear mechanism is provided on the second support, which is transmission-connected to the rear ends of the hollow lead screw and the inner lead screw to drive the hollow lead screw and the inner lead screw to rotate, the inner lead screw is threadedly matched with the reducer base, and the hollow lead screw is threadedly matched with the motor base.

[0004] The above solution uses a worm and worm gear mechanism and a lead screw mechanism to achieve the movement adjustment of the motor base, and further realizes the adjustment of the belt tightness. However, it mainly operates by manually rotating the worm and worm gear mechanism, and the labor intensity is still relatively large. At the same time, the worm of the worm and worm gear mechanism is arranged perpendicular to the axis of the lead screw, which causes the manual operation device to occupy a certain space above the worm and worm gear mechanism, and will be restricted when used in a narrow space for the motor installation position. In addition, in this solution, the distance between the first support and the second support is relatively far, and they are only connected by two slide rails. When adjusting the motor, there is a possibility of uneven force on the base structure, resulting in unstable connection between the support and the slide rail, and there are certain safety hazards. Summary of the Invention

[0017] Further, the lead screw has a flat head end, an assembly hole is arranged on the flat head end, an installation hole is arranged on the lead screw fixing seat, and the lead screw is bolted to the lead screw fixing seat through the assembly hole and the installation hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The features and performance of the present invention will be further described in detail below in conjunction with the embodiments.

[0030] Embodiment 1 of the adjustable motor base in the present invention:

[0031] The existing rapid movement motor slide rail device of the pumping unit uses a worm and worm gear mechanism and a lead screw mechanism to realize the movement adjustment of the motor base, and further realizes the adjustment of the belt tightness, but mainly operates by manually rotating the worm and worm gear mechanism, and the labor intensity is still relatively large.

[0032] To solve the above problems, the present utility model proposes an adjustable motor base. The adjustable motor base includes a first support and a second support which are oppositely arranged. Between the first support and the second support, there are at least two parallel and spaced rails. A motor driving seat and a motor free mounting seat are slidably mounted on the rails. A lead screw is connected to the motor driving seat. A worm and worm gear mechanism is further provided on the first support. The worm gear of the worm and worm gear mechanism is in transmission connection with the lead screw. One end of the worm of the worm and worm gear mechanism is connected to a driving motor, and the other end is connected to a manual rotating wheel.

[0033] In the present utility model, by connecting a driving motor and a manual rotating wheel to the two ends of the worm of the worm and worm gear mechanism respectively, during specific use, the double driving source input of the driving motor and the manual rotating wheel is utilized to drive the worm and worm gear mechanism to drive the lead screw to act respectively, so that the motor driving seat is driven by the lead screw to achieve automatic adjustment or manual adjustment, and further the position of the motor is adjusted. The process operation is simple, effectively reducing the labor intensity and improving the operation efficiency.

[0034] As Figure 1 shown, the adjustable motor base 100 of the present utility model includes a first support 8, a second support 1, rails 4, a motor driving seat 3, a motor free mounting seat 2, and a driving and executing mechanism. The first support 8 and the second support 1 are oppositely arranged. The first support 8 and the second support 1 are fixedly connected together by two rails 4 extending front and back. The two rails 4 are spaced left and right and arranged in parallel. The motor driving seat 3 and the motor free mounting seat 2 are slidably mounted on the rails.

[0035] In this embodiment, both the first support 8 and the second support 1 include a bottom plate 12 and a vertical plate 11. At the positions corresponding to the two rails 4 on the vertical plate 11, there are rail mounting holes (not marked in the figure) for fixedly assembling the rails 4; the first support 8 is also provided with a first through hole (not marked in the figure) for the lead screw 9 to pass through at the center of the connection line of the two rail mounting holes; both ends of the bottom plate 12 are provided with U-shaped notches to facilitate the fixed connection of the adjustable motor base of the present utility model with the pumping unit.

[0036] In this embodiment, a support connecting plate 10 is further connected between the first support 8 and the second support 1 corresponding to the rails 4. Specifically, there are two support connecting plates 10. The two support connecting plates 10 are respectively fixedly connected to the bottom of the vertical plate 11 and correspond to the connection positions of the rails 4 and the vertical plate 11, which can strengthen the firmness of the connection between the rails 4 and the support.

[0037] In this embodiment, the rails 4 are solid or hollow rails with a circular cross-section, which can effectively reduce the moving resistance of the guide sleeve 22.

[0038] The driving actuator includes a worm and worm gear mechanism 6, a driving motor 5, a manual rotating wheel 7, and a lead screw 9 that is in transmission cooperation with the worm and worm gear mechanism 6. The worm and worm gear mechanism 6 is installed on the first support 8. The worm and worm gear mechanism 6 at least includes a worm (not shown in the figure) and a worm gear (not shown in the figure) that meshes with the worm. The worm is perpendicular to the axis of the lead screw 9 and is horizontally arranged. One end of the worm is connected to the driving motor 5, and the other end of the worm is connected to the manual rotating wheel 7. Specifically, the two ends of the worm are directly connected to the driving motor 5 and the manual rotating wheel 7 respectively. The lead screw 9 has an external thread, and the inner cavity of the worm gear has an internal thread. The lead screw 9 meshes with the internal thread of the worm gear through the external thread. Thus, when the worm drives the worm gear to rotate, the rotation of the worm gear causes the lead screw 9 to move linearly along the axis. The worm gear and the lead screw 9 form a lead screw nut mechanism, and the worm and worm gear mechanism 6 and the lead screw 9 form a worm and lead screw mechanism. In this embodiment, the worm is located above the worm gear, and both the driving motor 5 and the worm are horizontally arranged. In this way, the worm and worm gear mechanism 6 has a dual driving source input provided by the driving motor 5 and the manual rotating wheel 7. During the use of the adjustable motor base of the present utility model, when any one of the driving sources fails, the other driving source can be used as a backup, avoiding the long-term shutdown of the pumping unit and affecting the production operation efficiency. In this embodiment, the worm and worm gear mechanism is a prior art, and other structures not described here will not be elaborated further.

[0039] In this embodiment, one end of the lead screw 9 away from the worm and worm gear mechanism 6 is flat-headed, and there is an assembly hole (not marked in the figure) on the flat-headed end of the lead screw 9; a lead screw fixing seat 31 for connecting with the lead screw 9 is fixedly arranged on the motor driving seat 3. The lead screw fixing seat 31 is in an inverted U shape, and there is an installation hole (not marked in the figure) on the U-shaped side wall of the lead screw fixing seat 31. A bolt and nut assembly (not marked in the figure) sequentially passes through the bolt hole of the lead screw fixing seat 31 and the assembly hole of the lead screw 9 to connect the lead screw 9 and the lead screw fixing seat 31.

[0040] In this embodiment, a fixing seat 81 for installing the worm and worm gear mechanism 6 is further arranged on the first support 8. The fixing seat 81 is in a U shape. One end of the U-shaped opening of the fixing seat 81 faces the first support 8 and is fixedly connected to the first support 8 by welding. The worm and worm gear mechanism 6 is fixedly connected to the fixing seat 81 by bolts. The fixing seat 81 is provided with a second through hole corresponding to the position of the first through hole. The lead screw 9 sequentially passes through the first through hole and the second through hole to cooperate with the worm and worm gear mechanism 6.

[0041] At the positions of the bottom of the motor driving seat 3 and the motor freely mounted seat 2 corresponding to the slide rail 4, guide sleeves 22 are fixedly arranged. The motor driving seat 3 and the motor freely mounted seat 2 are slidably assembled on the slide rail 4 through the guide sleeves 22, and the slide rail 4 passes through the guide sleeves 22. The motor driving seat 3 and the motor freely mounted seat 2 cooperate to mount the motor. When the motor driving seat 3 is adjusted in position under the action of the lead screw 9, the motor freely mounted seat 2 is synchronously guided and moved along the slide rail 4 with the motor driving seat 3 under the connection of the motor base. In this way, the cooperation between the motor driving seat 3 and the motor freely mounted seat 2 can be adapted to motors of different models and different sizes, improving the application range of the adjustable motor base of the present utility model.

[0042] In this embodiment, a plurality of motor fixing holes 21 for fixedly mounting the motor are provided on the motor driving seat 3 and the motor freely mounted seat 2. The motor fixing holes 21 constitute an adjustable mounting structure for fixedly mounting the motor. Specifically, the motor fixing holes 21 are strip-shaped through holes extending along the axial direction perpendicular to the slide rail. In this way, the installation of the motor in the axial direction of the slide rail can be adjusted according to the actual situation of the motor, suitable for motors of different specifications, and facilitating the installation and fixation of the motor.

[0043] In this embodiment, a time relay is further provided. The motor 5 can be driven by the time relay to drive the worm and worm gear mechanism 6 to drive and then drive the lead screw 9 to realize the horizontal movement of the motor, which can effectively improve the work efficiency and reduce the potential safety hazards caused by manual operation.

[0044] When the adjustable motor base of the present utility model is in use, when the pumping unit needs to install or replace the drive belt, it can be automatically operated by driving the motor 5 or manually operated by the manual runner 7 respectively. Specifically:

[0045] During automatic operation, the driving motor 5 drives the worm and worm gear mechanism 6 to act. The worm drives the lead screw 9 to move along the axial direction of the lead screw 9. The movement of the lead screw 9 drives the motor driving seat 3 to move along the axial direction of the slide rail 4, thereby realizing the adjustment of the belt tightness. When replacing the belt, the lead screw 9 drives the motor driving seat 3 to move towards the pumping unit to make the belt loose and then replace the belt. When the belt replacement or tightness adjustment is completed, the driving motor 5 is used to drive the worm and worm gear mechanism 6 to act in the reverse direction to reset the motor driving seat 3, completing the belt replacement or tightness adjustment. The whole process is simple to operate, reducing the labor intensity and improving the operation efficiency.

[0046] During manual operation, when the drive motor 5 fails to work properly, rotate the manual runner 7 to drive the worm and worm gear mechanism 6 to act. The worm drives the lead screw 9 to move along the axial direction of the lead screw 9. The movement of the lead screw 9 drives the motor active seat 3 to move along the axial direction of the slide rail 4, thereby realizing the adjustment of the belt tightness or the replacement of the belt. After replacing the belt or completing the adjustment of the belt tightness, reverse-rotate the manual runner 7 to reset the motor active seat 3, and complete the replacement of the belt or the adjustment of the belt tightness.

[0047] During the above operation process, the self-locking characteristic of the worm and worm gear can be utilized to lock the moving position of the motor.
