Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an intelligently adjustable oil pump motor mounting assembly. Background Art

[0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In the process of oil field exploitation, the oil pump is one of the key equipment. As its main driving force, the motor needs to be installed and adjusted stably and reliably. The motor pulley and the oil pump reduction box pulley are meshed with a belt. The motor output shaft drives the motor pulley to rotate, so as to realize the stable rotation of the oil pump reduction box pulley. However, at present, when the motor is installed, it is not convenient to match the position of the oil pump reduction box pulley, resulting in the following defects:

[0003] First, when the pumping unit is working, it is necessary to ensure that the belt between the pumping unit reduction box pulley and the motor pulley is tight, and the motor installation position and angle need to be adjusted continuously. During the adjustment process, bolts need to be installed and removed, which is time-consuming and laborious to adjust the installation position. In addition, if the belt is in a tight state, the load fluctuation generated by the motor operation is easy to cause mechanical shock, which will affect the service life of the equipment for a long time.

[0004] Second, when the current motor is damaged and needs to be replaced, the motor installation position needs to be readjusted. Especially when a motor of a different model needs to be replaced, it cannot be reinstalled in the previous position. The installation assembly needs to be disassembled and connected with the bolts on the longitudinal beam at the bottom of the pumping unit, and the motor installation position needs to be repeatedly adjusted to ensure that the belt is tightened, which is labor-intensive.

[0005] Third, as the belt wears over a long period of time, it is easy to cause the belt to break. If the belt breaks and the motor cannot be controlled to stop working in time, it is easy to cause waste of resources and affect the normal use of the oil pump. In view of this, we propose an intelligently adjustable oil pump motor installation component. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligently adjustable oil pump motor mounting assembly, which rotates and swings a certain amplitude along the inside of a composite bracket assembly through a self-adjusting mounting assembly, and utilizes the effect of the motor's own weight to automatically tighten the belt between the motor pulley and the oil pump reduction box pulley, thereby avoiding the time-consuming and labor-intensive adjustment of the motor mounting position.

[0007] To achieve the above object, the present invention provides an intelligently adjustable pumping unit motor mounting assembly, comprising at least a composite bracket assembly, wherein a self-adjusting mounting assembly is rotatably arranged between the composite bracket assemblies, and a hydraulic jacking assembly is arranged at the bottom of the self-adjusting mounting assembly away from the composite bracket assembly, wherein:

[0010] During the belt tensioning operation between the oil pump reduction box pulley and the motor pulley, the hydraulic jacking assembly senses the signal of belt breakage, assists in supporting the self-adjusting installation assembly, and controls the machine to stop working.

[0011] As a further improvement of the present technical solution, the composite bracket assembly includes at least two symmetrical support frames, and the bottom of the two support frames are fixed with a mounting plate for being installed on the bottom longitudinal beam of the oil pump by bolts.

[0014] As a further improvement of the present technical solution, the self-adjusting mounting assembly also includes a longitudinal fine-tuning assembly, which includes a longitudinal screw rod, which is rotatably arranged in a frame body formed by the inner cavity of the rotating swing arm frame, and the outer wall of the longitudinal screw rod is threadedly connected to a longitudinal threaded sleeve, and the outer wall of the longitudinal threaded sleeve is fixedly connected to the bottom of the motor mounting frame.

[0015] As a further improvement of the technical solution, the interior of the mounting sleeve is adapted to slide with the contour of the outer wall of the limiting frame;

[0016] An adapter plate is provided at the end of the motor mounting frame, and the adapter plate is adapted and slidable with the inner cavity size of the rotating swing arm frame.

[0017] As a further improvement of the technical solution, a plurality of mounting holes are provided on the top of the motor mounting frame, and the mounting holes are used for one-to-one installation corresponding to different motor base models.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the intelligently adjustable pumping unit motor mounting assembly, the composite bracket assembly is mounted on the bottom longitudinal beam of the pumping unit, so that the self-adjusting mounting assembly can rotate and swing to a certain extent along the inside of the composite bracket assembly, and the belt between the motor pulley and the pumping unit reduction box pulley is automatically tightened by utilizing the motor's own weight, thereby avoiding the time-consuming and laborious adjustment of the motor installation position.

[0022] 2. In the intelligently adjustable oil pump motor mounting assembly, the self-adjusting mounting assembly adopts a swing arm rotating structure. When the motor starts and runs, it can rotate and swing slightly, using the tension and toughness of the transmission belt to buffer mechanical shock, achieve flexible start and stop of the motor, and fully reduce the mechanical shock caused by load fluctuations, thereby increasing the service life of the equipment.

[0023] 3. In the intelligently adjustable oil pump motor mounting assembly, the motor can be driven by the self-adjusting mounting assembly to achieve fine-tuning of the XY axis, so that when different types of motors and different types of pulleys are replaced, there is no need to readjust the fixed position of the motor mounting device, thereby eliminating the trouble and work caused by re-adjusting the position of the motor mounting device when replacing the motor or pulley, and improving convenience.

[0024] 4. In the intelligently adjustable oil pump motor installation assembly, the hydraulic jacking assembly is located at the bottom of one end of the self-adjusting installation assembly away from the composite support assembly during the belt tensioning process. When the belt breaks, there is no belt pulling force at the motor output end, so that the self-adjusting installation assembly swings downward along the composite support assembly under the action of its own weight until it fits the hydraulic jacking assembly, senses the supporting force of the composite support assembly, outputs a break signal, and sends out a corresponding control command to stop the machine from working, thereby improving safety and avoiding waste of resources and dangerous accidents.

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In the process of oil field exploitation, the oil pump is one of the key equipment. As its main driving force, the motor needs to be installed and adjusted stably and reliably. The motor pulley and the oil pump reduction box pulley are meshed with a belt. The motor output shaft drives the motor pulley to rotate, so as to realize the stable rotation of the oil pump reduction box pulley. However, at present, when the motor is installed, it is not convenient to match the position of the oil pump reduction box pulley. Therefore, please refer to Figure 1-Figure 8 As shown, this embodiment provides an intelligently adjustable pumping unit motor mounting assembly, which at least includes a composite support assembly 100, a self-adjusting mounting assembly 200 is rotatably arranged between the composite support assemblies 100, and a hydraulic jacking assembly 300 is arranged at the bottom of the self-adjusting mounting assembly 200 away from the composite support assembly 100, wherein:

[0039] The composite support assembly 100 is used to be installed on the bottom longitudinal beam of the pumping unit and provide a support point for the self-adjusting mounting assembly 200 to rotate and swing;

[0040] The self-adjusting mounting assembly 200 drives the installed motor to rotate and swing around the center of the composite bracket assembly 100, and the belt is automatically tightened by the motor's own weight, and the center distance between the motor and the pumping unit reduction box pulley is finely adjusted;

[0041] During the belt tensioning operation between the oil pump reduction box pulley and the motor pulley, the hydraulic jacking assembly 300 senses the signal of belt breakage, assists in supporting the self-adjusting installation assembly 200, and controls the machine to stop working.

[0042] like Figure 1-Figure 2 As shown, the present invention takes into account that when the oil pump is working, in order to ensure that the belt between the oil pump reduction box pulley and the motor pulley is tightened, it is necessary to constantly adjust the position and angle of the motor installation. During the adjustment process, bolts need to be installed and removed, and it is time-consuming and laborious to adjust the installation position. In addition, if the belt is in a tightened state, the load fluctuation generated by the motor operation is prone to cause mechanical shock, which affects the service life of the equipment for a long time. Therefore, the composite bracket assembly 100 is installed on the bottom longitudinal beam of the oil pump, so that the self-adjusting installation assembly 200 can rotate and swing to a certain extent along the inside of the composite bracket assembly 100, and the belt between the motor pulley and the oil pump reduction box pulley is automatically tightened by the effect of the motor's own weight, thereby avoiding the time-consuming and labor-intensive adjustment of the motor installation position.

[0043] In addition, the self-adjusting mounting assembly 200 adopts a swing arm rotating structure, which can rotate and swing slightly when the motor is started and running, and use the tension and toughness of the transmission belt to buffer the mechanical impact, realize the flexible start and stop of the motor, and fully reduce the mechanical impact caused by load fluctuations, thereby increasing the service life of the equipment;

[0044] When the current motor is damaged and needs to be replaced, it is necessary to readjust the motor installation position. In particular, when a motor of a different model needs to be replaced, it cannot be reinstalled in the previous position. It is necessary to dismantle the bolt connection between the installation component and the longitudinal beam at the bottom of the oil pumping unit, and repeatedly adjust the motor installation position to ensure that the belt is tightened. The labor intensity is large. Therefore, the self-adjusting installation component 200 can drive the motor to achieve fine adjustment of the XY axis, so that when replacing motors of different models and pulleys of different models, there is no need to adjust the fixed position of the motor installation device again, eliminating the trouble and work caused by re-adjusting the position of the motor installation device when replacing the motor or pulley, thereby improving convenience.

[0045] As the belt wears over a long period of time, it is easy to cause the belt to break. If the belt breakage cannot be detected in time and the motor cannot be controlled to stop working, it is easy to cause waste of resources and affect the normal use of the oil pump. Therefore, during the process of belt tensioning, the hydraulic jacking assembly 300 is located at the bottom of the end of the self-adjusting installation assembly 200 away from the composite support assembly 100. When the belt breaks, there is no belt pulling force at the output end of the motor, so that the self-adjusting installation assembly 200 swings downward along the composite support assembly 100 under the action of its own weight until it fits the hydraulic jacking assembly 300, senses the supporting force of the composite support assembly 100, outputs a breakage signal, and sends out a corresponding control command to stop the machine from working, thereby improving safety and avoiding waste of resources and dangerous accidents.

[0046] On the basis of the above, the specific structure needs to be disclosed in detail:

[0047] First, to realize that the composite support assembly 100 can support the self-adjusting mounting assembly 200 located on the bottom longitudinal beam of the pumping unit to realize the installation support of the motor, it is necessary to disclose the structure of the composite support assembly 100 in detail, please refer to Figure 3 As shown, the composite bracket assembly 100 includes at least two symmetrical support frames 110, and the bottom of the two support frames 110 are fixedly provided with a mounting plate 130 for being installed on the bottom longitudinal beam of the oil pump through bolts. A bearing member 120 is penetrated through the center of the inner wall of the support frame 110, and a reinforcing steel plate 121 is provided between the bearing member 120 and the outer wall of the support frame 110. The reinforcing steel plate 121 can improve the installation strength of the bearing member 120 and the support frame 110, improve safety, and achieve higher stability and strength when the self-adjusting mounting assembly 200 is located between the two bearing members 120 and rotates.

[0048] Then, the motor is fixed to the self-adjusting mounting assembly 200, so as to control the motor to rotate along the inside of the bearing member 120 under the action of its own weight, so that the belt is automatically tightened. The structure of the self-adjusting mounting assembly 200 needs to be further disclosed, please refer to Figure 4 and Figure 5As shown, the self-adjusting mounting assembly 200 at least includes a rotating rod 210 installed between two bearing members 120, and the rotating rod 210 is rotatably arranged between two supporting frames 110. A limit frame 211 is fixedly sleeved on the outer wall of the rotating rod 210, and an installation sleeve 220 is provided on the outer wall of the limit frame 211. A rotating swing arm frame 221 is fixedly connected to the outer wall of the installation sleeve 220. A motor mounting frame 230 is provided on the top of the rotating swing arm frame 221. The motor is fixedly mounted by the motor mounting frame 230, so that the motor can rotate and swing along with the motor mounting frame 230 and the rotating swing arm frame 221. Since the support point of the rotating swing arm frame 221 is on the outer wall of the rotating rod 210, that is, the rotating rod 210 rotates inside the bearing member 120, the limit frame 211 and the mounting sleeve 220 also rotate, driving the rotating swing arm frame 221 to swing. Therefore, under the gravity of the motor, the motor has a tendency to move downward. With the pull of the belt between the pumping unit reduction box pulley and the motor pulley, the motor can no longer rotate downward. At the same time, the motor can adapt to the belt tension amplitude as the rotating swing arm frame 221 rotates and swings, ensuring that the belt remains in a tensioned state.

[0049] Moreover, when the motor generates vibration, the rotating swing arm frame 221 can receive the vibration and shake slightly, and utilize the tension and toughness of the transmission belt to buffer the mechanical shock, realize the flexible start and stop of the motor, and fully reduce the mechanical shock caused by load fluctuation, thereby improving safety.

[0050] Furthermore, when the motor is damaged and needs to be replaced, the self-adjusting mounting assembly 200 can drive the motor to achieve fine adjustment of the XY axis, so that when replacing different types of motors and different types of pulleys, there is no need to adjust the fixed position of the motor mounting device again. Figure 5 As shown, first of all, the lateral (X-axis) fine adjustment must be satisfied, so that the self-adjusting mounting assembly 200 also includes a lateral fine adjustment assembly 240, and the lateral fine adjustment assembly 240 includes a bearing bracket 241 fixed to the outer wall of the limit frame 211, and a lateral screw rod 242 for rotation is arranged inside the bearing bracket 241, and the outer wall of the lateral screw rod 242 is threadedly connected with a lateral threaded sleeve 243, and the outer wall of the lateral threaded sleeve 243 is fixed to the outer wall of the mounting sleeve 220. By rotating the lateral screw rod 242, the lateral threaded sleeve 243 slides along the thread of the outer wall of the lateral screw rod 242, thereby driving the mounting sleeve 220 and the rotating swing arm frame 221 to slide, and fine-tuning the position of the motor in the X-axis direction to achieve a certain degree of axial movement, thereby adjusting the horizontal distance between the motor output end and the pulley of the oil pumping unit reduction box, and adapting to the installation and adjustment of motors of different machine bases;

[0051] In addition, the lateral position can be changed by sliding between the transverse threaded sleeve 243 and the limit frame 211. When sliding to a suitable position, the stability of the connection between the transverse threaded sleeve 243 and the limit frame 211 can be ensured by means of a bolt thread passing through the transverse threaded sleeve 243 and the limit frame 211. When sliding, the bolt can be removed. At the same time, the transverse threaded sleeve 243 is threadedly transmitted along the transverse screw rod 242, which is conducive to ensuring the stability of sliding.

[0052] Next, in order to meet the longitudinal (Y-axis) fine adjustment, the self-adjusting mounting assembly 200 also includes a longitudinal fine adjustment assembly 250, which includes a longitudinal screw rod 251, which is rotatably arranged in the frame body formed by the inner cavity of the rotating swing arm frame 221, and the outer wall of the longitudinal screw rod 251 is threadedly connected with a longitudinal threaded sleeve 252, and the outer wall of the longitudinal threaded sleeve 252 is fixedly connected to the bottom of the motor mounting frame 230. By rotating the longitudinal screw rod 251 inside the rotating swing arm frame 221, the longitudinal threaded sleeve 252 slides along the thread of the outer wall of the longitudinal screw rod 251, thereby driving the motor mounting frame 230 to move longitudinally, realizing a certain range of movement in the longitudinal direction, and quickly adjusting the center distance between the motor and the pulley of the oil pumping unit reduction box, so as to adapt to the installation and adjustment of motors with different machine bases and the installation and adjustment of pulleys with different diameters;

[0053] At the same time, the transverse threaded sleeve 243 and the longitudinal threaded sleeve 252 adopt a structure of a flat plate plus fixed screws, which eliminates the movable gap in the structure, fundamentally eliminates the vibration and resonance caused by the existence of the gap, and improves the structural stability.

[0054] Specifically, when the rotating swing arm frame 221 moves horizontally, in order to limit the direction of the horizontal movement, when the motor mounting frame 230 moves longitudinally, in order to limit the direction of the longitudinal movement, the inside of the mounting sleeve 220 is adapted to slide with the contour of the outer wall of the limiting frame 211. When the horizontal movement is realized, the mounting sleeve 220 completely slides with the contour of the outer wall of the limiting frame 211 to perform horizontal limitation and improve the sliding stability.

[0055] An adapter plate 232 is provided at the end of the motor mounting frame 230. The adapter plate 232 is adapted to slide with the inner size of the rotating swing arm frame 221. When the motor mounting frame 230 slides, the adapter plate 232 is adapted to slide along the inside of the rotating swing arm frame 221 to limit the longitudinal sliding direction and improve the sliding stability.

[0056] At present, the motor is fixed by connecting the mounting holes to the motor base through bolt threads. Therefore, in order to ensure that the motor mounting frame 230 can adapt to different motor base models, a plurality of mounting holes 231 are opened on the top of the motor mounting frame 230. The mounting holes 231 are used for one-to-one installation of different motor base models. During installation, you only need to select the appropriate mounting holes 231 according to the motor model, thereby increasing the scope of use.

[0057] It is worth noting that when the belt breaks, the hydraulic lifting assembly 300 is triggered to issue a control command to stop the machine from breaking the belt, and the hydraulic lifting assembly 300 can assist in supporting the end of the rotating swing arm frame 221. Figure 6 , Figure 7 and Figure 8 As shown, the hydraulic lifting assembly 300 shown includes at least a fixing frame 310 installed on the bottom longitudinal beam of the oil pumping unit, a hydraulic cylinder 320 is provided in the inner cavity of the fixing frame 310, and a break detection component 330 is also provided inside the fixing frame 310. The hydraulic cylinder 320 is used to ensure that the belt between the oil pumping unit reduction box pulley and the motor pulley is initially tightened, so that the piston rod of the hydraulic cylinder 320 can make a linear motion, so that the bottom of the rotating swing arm frame 221 is supported on the top of the piston rod of the hydraulic cylinder 320 for auxiliary support. As the belt is engaged and sleeved between the oil pumping unit reduction box pulley and the motor pulley, the piston rod of the hydraulic cylinder 320 moves downward and disengages from the bottom of the rotating swing arm frame 221, and the belt is adaptively tightened under the action of the motor's own gravity.

[0058] Specifically, the hydraulic cylinder 320 and the break detection component 330 are both located below the rotating swing arm frame 221 near the edge, and during the belt tensioning process, the distance between the bottom of the rotating swing arm frame 221 and the break detection component 330 is a, a=25mm-40mm, wherein the break detection component 330 can use an acceleration sensor to detect gravity changes. The acceleration sensor can measure the acceleration of an object, thereby indirectly detecting the effect of gravity. The acceleration sensor is connected to a microcontroller such as Arduino, Raspberry Pi, etc., and signal processing and control logic are implemented through programming. When gravity is detected, it means that the rotating swing arm frame 221 rotates and contacts the break detection component 330, that is, the belt is broken. When the acceleration sensor detects a specific acceleration indicating that the object is falling, the microcontroller can recognize this signal. The microcontroller can trigger sound, light flash or other forms of alarm signals to remind the operator or relevant personnel, and control the power supply of the machine or related actuators through the microcontroller to stop the operation of the machine (motor, oil pump) to avoid further damage or safety problems.

[0059] In summary, the comprehensive working principle of the present invention is:

[0060] Place the composite support assembly 100 and the hydraulic jacking assembly 300 on the bottom longitudinal beam of the oil pumping unit, determine the center distance between the motor pulley and the oil pumping unit reduction box pulley according to the oil pumping unit belt model, move the motor mounting device to a suitable position, make the bottom plane of the composite support assembly 100 and the hydraulic jacking assembly 300 flush with the upper plane of the oil pumping unit longitudinal beam, move the hydraulic jacking assembly 300, make the piston rod of the hydraulic jacking assembly 300 flush with the outer end surface of the rotating swing arm frame (close to the bottom of the edge), use the oil field general I-beam fixing gasket to connect and tighten the hydraulic jacking assembly 300 to the I-beam, adjust the support height of the hydraulic cylinder 320, make the motor mounting frame 230 in a horizontal position, select the corresponding mounting hole 231 on the motor mounting frame 230 according to the motor model, fix the motor, and tighten the fixing bolts, loosen the mounting sleeve 220 and the limit frame 2 11, move the adjusting position laterally to make the motor pulley end face and the pumping unit reduction box pulley end face in a straight line, lock the fixing bolts between the mounting sleeve 220 and the limit frame 211, adjust the supporting height of the hydraulic jacking assembly, connect the pumping unit belt and the two pulleys into the groove, release the pressure of the hydraulic jacking assembly, so that the rotating swing arm frame 221 is in a suspended state under the action of the belt, measure the clearance size a between the sliding sleeve motor mounting plate fixing frame and the upper plane of the hydraulic jacking assembly, a is more suitable between 25 and 40 mm. If the size is not suitable, the motor mounting frame 230 can be fine-tuned longitudinally to make a within the specified range, connect the motor power line, and after the specified safety inspection, power on the motor for trial operation to check whether there is any looseness or abnormal noise. If there is no problem, shut down and cut off the power, connect the belt break signal line to the motor control system, and it can operate normally.
