A motor adjusting base and its control method

Abstract

The present invention discloses a motor adjusting seat and its control method, which relates to the technical field of motors. In the present invention, the rotational thrust of the guiding cone by the inner wall of the guiding groove will cause the guiding cone to drive the supporting seat and the motor body to rotate synchronously. The rotation angle converted from the vertical lifting force is very fine and easy to control. The rolling cooperation between the movable ball and the annular track makes the small-angle adjustment of the motor more labor-saving, easier and controllable. At this time, the staff only needs to slowly pressurize the jack while observing and judging the angle that needs to be further adjusted according to experience. It saves time and effort, and the stability of the motor is relatively high due to the support of the movable balls distributed at equal angles and limited by the annular track. Only the angle of fine adjustment of the motor body needs to be grasped. It cleverly converts the horizontal layer problem of difficult angle control to the vertical layer. Simply put, it controls the angle by adjusting the height, which is labor-saving and more stable, and is more suitable for the staff to debug the angle of the motor.

Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to a motor adjusting seat and a control method thereof. Background Art

[0002] During daily production activities, motors are often used as power sources. For some large motors, due to their large equipment power, a fixed seat generally needs to be configured as a power source at the front end of the equipment or production line to maintain stability during operation. For example, an adjustable motor base with the publication number CN113659766A fixes the motor in the device and drives the base to adjust the lifting component and the base to adjust the rotating component through the base adjustment driving component. When performing lifting control, the connection relationship between the lifting adjustment connecting component and the base adjustment driving component is controlled through the power contact transmission control component to realize the adjustment change of lifting or rotation, and then the height of the motor base and the motor direction are freely adjusted.

[0003] However, in actual production activities for medium and large motors, generally no large-scale angle and height adjustments are made after the initial hoisting, installation and commissioning. This is because the motor needs to be stably connected to the production equipment or production line as an output source and can only be used after complex commissioning. The rational utilization of space (angle and height) has already undergone strict commissioning and verification. During the later operation and maintenance of the equipment, the demand for height adjustment of the motor is very small. Even if height adjustment is required, the motor is lifted together with the subsequent production equipment to adjust the height. Adjusting the height of the motor alone will require complex commissioning and verification again as in the initial installation before it can be put into use. Generally, it is not recommended to adjust the height alone;

[0004] Currently, for adjustments of a relatively large angle (more than 90 degrees), the conventional method is to first rotate the motor by a large angle through hoisting or the method in the above patent technology, and then perform fine adjustment. It is relatively easy to lift the motor through equipment or other existing methods, but it is very difficult to accurately control the motor to land unchanged while fine-tuning the angle:

[0005] Currently, the key points and difficulties in motor adjustment do not lie in large-angle adjustment, but in fine adjustment of the angle. Currently, the optimal motor angle adjustment method requires, on the one hand, the adjustability of the base, and on the other hand, the fine commissioning cooperation of the staff. Neither can be missing. Because the motor is often in an irregular shape and can only maintain the center of gravity stability by relying on the contact support between surfaces. Once a large-weight motor leaves the ground, its controllability will become very poor. No matter how refined the angle adjustment equipment is, ultimately, the staff needs to repeatedly compare (the deviation angle of the output center) between the front-end and rear-end equipment and perform multiple commissioning steps to gradually reduce the angle difference and finally reach the coaxial state.

[0006] Therefore, the present invention proposes a highly stable auxiliary motor adjustment seat that switches the support method through hydraulic assistance and controls the motor angle by using the height change of the guiding convex disk. Summary of the Invention

[0007] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a motor adjustment seat and its control method to solve the problem proposed in the above background technology that for adjustments of relatively large angles (above 90 degrees), the conventional method is to first rotate the motor by a relatively large angle through hoisting or the method in the above patent technology, and then perform fine adjustment. It is relatively easy to lift the motor by equipment or other existing means, but it is very difficult to accurately control the motor to land unchanged while fine-tuning the angle.

[0008] To achieve the above object, the present invention provides the following technical solution: A motor adjustment seat includes a fixed seat, a motor body installed directly above the fixed seat, a supporting seat fixedly connected to the lower end of the motor body, and a jack fixed on the surface of the fixed seat. It also includes a first hydraulic cylinder fixed on the upper surface of the fixed seat for connecting the hydraulic output of the jack, a guiding convex disk arranged directly above the first hydraulic cylinder for fine-tuning the angle of the motor body based on its own height change, and a plurality of guiding cones arranged at equal angles between the guiding convex disk and the supporting seat for switching the supporting method of the motor body by changing the contact method with the fixed seat. A telescopic mechanism for connecting the hydraulic output of the first hydraulic cylinder is installed inside the guiding cone, and a hydraulic transmission component is installed between the telescopic end of the jack and the first hydraulic cylinder;

[0009] The guiding convex disk is used to guide the guiding cone, and a movable ball is arranged at the lower end of the guiding cone, which adaptively extends during the adjustment of the angle of the motor body and changes the fitting and fixed supporting method of the motor body into a rolling supporting method.

[0010] Preferably, a hydraulic piston is sealed and slidably arranged in the oil cavity inside the first hydraulic cylinder. The upper end of the hydraulic piston penetrates above the first hydraulic cylinder and is fixedly connected with a T-shaped rod, and an adapter gasket is slidably arranged on the outer wall of the T-shaped rod;

[0011] The lower surface of the adapter gasket is provided with a friction groove that fits and matches the upper end of the hydraulic piston.

[0012] Preferably, an annular piston plate is fixed on the upper surface of the adapter gasket, and an annular oil cavity is opened at the corresponding lower end of the guiding convex disk. The upper end of the annular piston plate is sealed and slidably arranged inside the annular oil cavity.

[0013] Preferably, a plurality of liquid outlet pipes are fixedly and equally angledly penetrated at the upper end of the annular oil cavity, and the upper ends of the liquid outlet pipes are penetrated and connected with hydraulic hoses;

[0014] The liquid outlet pipe is a rigid pipe.

[0015] Preferably, the inside of the guiding convex disc is provided with guiding grooves corresponding to the number of guiding cones at equal angles, and a hydraulic cavity is arranged at the center of the guiding cone;

[0016] A communicating pipe is fixedly connected through the upper end of the hydraulic cavity, and the outer end of the communicating pipe is connected through the end of the hydraulic hose.

[0017] Preferably, the large-diameter end of the guiding cone is fixed to the lower surface of the supporting seat, and the small-diameter end of the guiding cone is attached to the upper surface of the fixing seat.

[0018] Preferably, the guiding groove is an arc design with a gradually changing width, and the guiding cone is slidably arranged inside the guiding groove in a fitting manner.

[0019] Preferably, for the piston part and the movable ball, the piston part is telescopically and slidably arranged inside the hydraulic cavity, a ball sleeve is fixed to the lower end of the piston part, and the movable ball is rotatably arranged inside the ball sleeve in a fitting manner;

[0020] A return spring is wound around the outer wall of the piston part, one end of the return spring is welded to the end of the piston part, and the other end of the return spring is fixed to the inner wall of the hydraulic cavity;

[0021] The lower end of the guiding cone is provided with a retracting groove capable of retracting the movable ball, and an annular track adapted to the movable ball is arranged on the upper surface of the fixing seat.

[0022] Preferably, the hydraulic transmission assembly includes a second hydraulic cylinder and a liquid guiding pipe. A piston piece is fixed to the upper end of the telescopic end of the jack. The lower end of the second hydraulic cylinder is of an open type and is fixedly connected to the upper end of the jack cylinder body component, and the piston piece is hermetically and slidably arranged inside the second hydraulic cylinder;

[0023] One end of the liquid guiding pipe is connected through the upper end of the second hydraulic cylinder, and the other end of the liquid guiding pipe is connected through the oil cavity inside the first hydraulic cylinder.

[0024] A control method for a motor adjusting seat, the control method comprising the following steps:

[0025] First stroke: The jack jacks up the hydraulic piston in a hydraulic form. The jacked-up hydraulic piston will again push out the piston part inside the guiding cone in a hydraulically driven manner and slightly jack up the guiding cone, realizing the switching of the contact bottom mode of the movable ball and the guiding cone;

[0026] Second stroke: The hydraulic piston continues to extend to vertically lift the guiding convex disc, and uses the guiding groove inside the guiding convex disc to realize the rotational drive of the guiding cone, forcing the guiding cone to drive the motor body to rotate for angle fine adjustment;

[0027] Landing: While releasing the output of the jack, the entire hydraulic system is depressurized, the way the moving ball touches the guiding cone bottom is switched again, and the motor body lands at the adjusted angle.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] The present invention uses the labor-saving jacking of the jack to inject the hydraulic oil inside the second hydraulic cylinder into the oil cavity of the first hydraulic cylinder through the liquid guiding pipe and jack up the hydraulic piston upward. Immediately afterwards, the connecting gasket is pushed vertically upward, and the full hydraulic oil inside the annular oil cavity is sequentially injected into the hydraulic cavity of the guiding cone through the liquid outlet pipe and the hydraulic hose, so that the piston part gradually descends, gradually pushing the moving ball rotatably connected at the lower end into the annular track and slightly jacking up the guiding cone, thereby realizing the change of the way the guiding cone touches the bottom. Without losing stability, the frictional resistance during the adjustment of the motor angle is greatly reduced;

[0030] Then the hydraulic action continues. The continuously jacked-up hydraulic piston will directly drive the guiding convex disk to move vertically upward. When the guiding convex disk moves vertically upward, the inner wall of the guiding groove with a gradually changing width will gradually generate a rotational thrust on the conical wall of the guiding cone. At the same time, since the supporting force received at the lower end of the guiding cone is replaced by the rolling contact between the moving ball and the annular track, the rotational thrust of the inner walls of multiple guiding grooves on multiple guiding cones will cause the guiding cone to drive the supporting seat and the motor body to rotate synchronously. The rotational angle transformed from the vertical lifting force is very fine and easy to control. At the same time, through the rolling cooperation between the moving ball and the annular track, the small-angle adjustment of the motor body is more labor-saving, easy and controllable. At this time, the staff only needs to slowly pressurize the jack while observing and judging the angle that needs to be further adjusted according to experience, which saves time and effort. Moreover, due to the support of the moving balls distributed at equal angles and limited by the annular track, the stability of the motor body is relatively high. Only the angle of the fine adjustment of the motor body needs to be grasped. The problem of the horizontal level that is difficult to accurately control the angle is cleverly converted to the vertical level. Simply put, the angle is controlled by adjusting the height, which is labor-saving and more stable, and is more suitable for the staff to debug the motor angle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of 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.

[0044] See also Figures 1 to 11, the present invention provides a technical solution: a motor adjusting seat, which includes a fixed seat 1, a motor body 6 installed directly above the fixed seat 1, a supporting seat 4 fixedly connected to the lower end of the motor body 6, and a jack 7 fixed on the surface of the fixed seat 1. It further includes a first hydraulic cylinder 2 fixed on the upper surface of the fixed seat 1 for connecting the hydraulic output of the jack 7, a guiding convex disk 3 arranged directly above the first hydraulic cylinder 2 for finely adjusting the angle of the motor body 6 based on the change of its own height, and a plurality of guiding cones 5 arranged at equal angles between the guiding convex disk 3 and the supporting seat 4 for switching the supporting mode of the motor body 6 by changing the contact mode with the fixed seat 1. A telescopic mechanism for connecting the hydraulic output of the first hydraulic cylinder 2 is installed inside the guiding cone 5, and a hydraulic transmission component is installed between the telescopic end of the jack 7 and the first hydraulic cylinder 2;

[0045] The guiding convex disk 3 is used to guide the guiding cone 5, and a movable ball 52 is arranged at the lower end of the guiding cone 5, which adaptively extends when adjusting the angle of the motor body 6 and changes the fitting and fixed supporting mode of the motor body 6 to a rolling supporting mode.

[0046] As a further implementation manner of the present invention, the motor body 6 and the supporting seat 4 are fixedly connected by threads. When the motor body 6 is operating, the first hydraulic cylinder 2 is fixed on the upper surface of the fixed seat 1. The first hydraulic cylinder 2 limits the hydraulic piston 21, the hydraulic piston 21 limits the connecting gasket 22, the connecting gasket 22 limits the guiding convex disk 3, and the guiding convex disk 3 limits the guiding cone 5 through the guiding groove 34. The upper end of the guiding cone 5 is fixedly connected to the supporting seat 4. Therefore, the limiting of the motor body 6 is indirectly realized by a single fixing part of the first hydraulic cylinder 2. At the same time, the lower end of the guiding cone 5 is closely attached to the upper surface of the fixed seat 1. Therefore, the main support of the motor body 6 is implemented by the guiding cones 5 evenly distributed at the lower end. When adjusting the angle, the supporting mode of the motor body 6 is switched from the surface support at the lower end of the guiding cone 5 to the rolling support of the movable ball 52 to reduce the frictional resistance when adjusting the angle of the motor body 6;

[0047] The hydraulic transmission component is used to transmit the labor-saving output of the jack 7 in the form of hydraulic pressure into the first hydraulic cylinder 2. Through the first stroke of the extension of the hydraulic piston 21, the hydraulic output is transmitted to the telescopic mechanism inside the alignment cone 5, so that the movable ball 52 at the lower end of the piston part 51 extends to fit into the annular track 11 and slightly jacks up the alignment cone 5. Then, after the first stroke of the extension of the hydraulic piston 21 ends, the hydraulic piston 21 will continue to extend the second stroke, and the alignment convex disk 3 is vertically pushed up through the connecting gasket 22 (at this time, the upper end of the annular piston plate on the upper surface of the connecting gasket 22 presses tightly against the inner wall of the annular oil cavity 31. However, since the movable ball 52 can effectively reduce the rolling friction, the rotational force that drives the alignment cone 5 to drive the support seat 4 installed with the motor body 6 is smaller than the resistance of the alignment groove 34 sliding along the surface of the alignment cone 5, and the upward hydraulic driving force received by the alignment convex disk 3 is greater than the frictional resistance and the gravity obstruction above the support seat 4. Therefore, when the hydraulic pressure continues, the alignment convex disk 3 mainly undergoes a vertical upward movement). When the alignment convex disk 3 moves vertically upward, the inner wall of the alignment groove 34 with a gradually changing width will gradually generate a rotational thrust on the conical wall of the alignment cone 5. At the same time, since the supporting force received by the lower end of the alignment cone 5 is replaced by the contact between the movable ball 52 and the annular track 11, the rotational thrust of the inner walls of multiple alignment grooves 34 on multiple alignment cones 5 will cause the alignment cone 5 to drive the support seat 4 and the motor body 6 to rotate synchronously. The rotation angle converted from the vertical lifting force is very fine and easy to control. At the same time, through the rolling cooperation between the movable ball 52 and the annular track 11 and the reduction of the gravity exerted by the motor body 6 between the alignment cone 5 and the fixed seat 1, the small-angle adjustment of the motor body 6 becomes more labor-saving, easy, and controllable (the reason for the reduction of the gravity exerted on the alignment cone 5 and the fixed seat 1 is that the shared force becomes smaller rather than the gravity becoming smaller).

[0048] As a further embodiment of the present invention, a hydraulic piston 21 is sealingly and slidably arranged in the oil cavity inside the first hydraulic cylinder 2. The upper end of the hydraulic piston 21 penetrates above the first hydraulic cylinder 2 and is fixedly connected with a T-shaped rod, and a connecting gasket 22 is slidably arranged on the outer wall of the T-shaped rod;

[0049] The lower surface of the connecting gasket 22 is provided with a friction groove that fits and matches the upper end of the hydraulic piston 21.

[0050] When the hydraulic pressure occurs, the upper end of the hydraulic piston 21 will gradually reach a state of being tightly fitted with the friction groove. With the weight of the large-weight motor body 6 added to the alignment convex disk 3, the tightly fitted state can be understood as a locked state, which only provides the vertical lifting force for the alignment convex disk 3, and the alignment convex disk 3 cannot rotate.

[0051] As a further embodiment of the present invention, an annular piston plate is fixed on the upper surface of the connecting gasket 22, and an annular oil cavity 31 is opened at the lower end of the alignment convex disk 3 corresponding to the annular piston plate, and the upper end of the annular piston plate is sealingly and slidably arranged inside the annular oil cavity 31.

[0052] A plurality of liquid outlet pipes 32 are fixedly penetrated through the upper end of the annular oil cavity 31 at equal angles, and a hydraulic hose 33 is penetrated and connected to the upper end of the liquid outlet pipe 32;

[0053] The liquid outlet pipe 32 is a rigid pipe.

[0054] The annular oil cavity 31 is slidably matched within the annular oil cavity 31. When the connecting gasket 22 is stressed and moves upward, the hydraulic oil inside the annular oil cavity 31 will be stably injected into the inside of the guiding cone 5 through the liquid outlet pipe 32 and the hydraulic hose 33, so as to eject the telescopic mechanism inside the guiding cone 5.

[0055] As a further embodiment of the present invention, guiding slots 34 corresponding to the number of guiding cones 5 are penetrated through the guiding convex disk 3 at equal angles, and a hydraulic cavity is opened at the center of the guiding cone 5;

[0056] A communicating pipe is fixedly penetrated through the upper end of the hydraulic cavity, and the outer end of the communicating pipe is penetrated and connected to the end of the hydraulic hose 33.

[0057] After the hydraulic cavity receives the hydraulic oil transmitted from the annular oil cavity 31, it will eject the piston member 51 and the movable ball 52, so that the lower end of the movable ball 52 falls into the annular track 11 opened on the upper surface of the fixed seat 1, thereby facilitating the subsequent fine adjustment of the angle of the guiding cone 5.

[0058] As a further embodiment of the present invention, the large-diameter end of the guiding cone 5 is fixed to the lower surface of the supporting seat 4, and the small-diameter end of the guiding cone 5 is attached to the upper surface of the fixed seat 1.

[0059] Without adjusting the angle of the motor body 6, the guiding cones 5 equally distributed from below of the supporting seat 4 can be regarded as fixed struts for supporting the motor body 6. When adjusting the angle of the motor body 6, these equally distributed struts will turn into movable struts that can roll along the annular track 11 under hydraulic assistance.

[0060] As a further embodiment of the present invention, the guiding slot 34 is designed as an arc with a gradually changing width, and the guiding cone 5 is slidably arranged in the guiding slot 34 in a fitting manner.

[0061] The vertically rising guiding convex disk 3 will drive the guiding slot 34 to rise vertically. Since the side wall of the guiding cone 5 is in fitting match with the guiding slot 34 and the large-diameter end of the guiding cone 5 faces upward, that is to say, the guiding cone 5 becomes thicker upwards. If the guiding cone 5 cannot change its angle, the guiding slot 34 cannot follow the guiding convex disk 3 to rise vertically. However, the lower end of the guiding cone 5 can change its angle and the width of the guiding slot 34 is gradually changing. Therefore, under the vertical resistance of the guiding slot 34, the guiding cone 5 has to deviate in angle to meet the vertical rising stroke of the guiding slot 34.

[0062] As a further embodiment of the present invention, the telescopic mechanism includes a piston member 51 and a movable ball 52. The piston member 51 is telescopically and slidably arranged inside the hydraulic chamber. A ball sleeve is fixed to the lower end of the piston member 51, and the movable ball 52 is rotatably arranged in the ball sleeve in a fitting manner.

[0063] A return spring 53 is wound around the outer wall of the piston member 51. One end of the return spring 53 is welded to the end of the piston member 51, and the other end of the return spring 53 is fixed to the inner wall of the hydraulic chamber.

[0064] An indentation groove for retracting the movable ball 52 is formed at the lower end of the guiding cone 5, and an annular track 11 that fits the movable ball 52 is formed on the upper surface of the fixed seat 1.

[0065] The fixed connection of the ball sleeve to the lower end of the piston member 51 and the rotatable arrangement of the movable ball 52 in the ball sleeve in a fitting manner are prior arts and will not be elaborated here. The return spring 53 is only used to retract the piston member 51 when the hydraulic pressure is released and is not used for bearing weight.

[0066] As a further embodiment of the present invention, the hydraulic transmission assembly includes a second hydraulic cylinder 71 and a liquid guide pipe 72. A piston piece is fixed to the upper end of the telescopic end of the jack 7, and the upper end of the cylinder body component of the jack 7 is fixedly connected to the second hydraulic cylinder 71 with an open lower end. The piston piece is hermetically and slidably arranged inside the second hydraulic cylinder 71.

[0067] The upper end of the second hydraulic cylinder 71 is connected to one end of the liquid guide pipe 72 in a penetrating manner, and the other end of the liquid guide pipe 72 is connected to the oil chamber inside the first hydraulic cylinder 2 in a penetrating manner.

[0068] The jack 7, as a labor-saving power source, is a prior art. The working principle of the jack 7 will not be further described herein. When the telescopic end of the jack 7 extends, the hydraulic oil inside the second hydraulic cylinder 71 will be stably injected into the first hydraulic cylinder 2 through the liquid guide pipe 72 to achieve the connection of the hydraulic pressure.

[0069] A control method for a motor adjusting seat, the control method including the following steps:

[0070] First stroke: The jack 7 jacks up the hydraulic piston 21 in a hydraulic form. The jacked-up hydraulic piston 21 will then push out the piston member 51 inside the guiding cone 5 in a hydraulic driving manner and slightly jack up the guiding cone 5, realizing the switching of the contact bottom mode of the movable ball 52 (when adjusting the angle, the supporting mode of the motor body 6 will be switched from the surface support at the lower end of the guiding cone 5 to the rolling support of the movable ball 52 to reduce the frictional resistance when adjusting the angle of the motor body 6).

[0071] Second stroke: The hydraulic piston 21 continues to extend to vertically lift the centering cam 3, and the internal centering groove 34 of the centering cam 3 is used to realize the rotational drive of the centering cone 5, forcing the centering cone 5 to drive the motor body 6 to rotate to achieve angle fine-tuning;

[0072] Falling in place: While releasing the output of the jack 7, the entire hydraulic system is depressurized, and the contact method between the movable ball 52 and the centering cone 5 is switched again, and the motor body 6 falls in place at the adjusted angle.

[0073] Working principle: When using this motor adjusting seat and its control method, it should be clear that when the motor body 6 is normally installed, the motor body 6 and the supporting seat 4 are fixedly connected by threads. The first hydraulic cylinder 2 is fixed on the upper surface of the fixed seat 1. The first hydraulic cylinder 2 limits the hydraulic piston 21, the hydraulic piston 21 limits the connecting gasket 22, the connecting gasket 22 limits the centering cam 3, and the centering cam 3 limits the centering cone 5 through the centering groove 34. The upper end of the centering cone 5 is fixedly connected to the supporting seat 4. Therefore, the limit of the motor body 6 is indirectly realized by a fixing part of the first hydraulic cylinder 2. At the same time, the lower end of the centering cone 5 closely adheres to the upper surface of the fixed seat 1. Therefore, the main support of the motor body 6 is implemented by the centering cones 5 evenly distributed at the lower end. In addition, for some motor bodies 6 that are greatly affected by vibration, bolt seats can be welded around the centering cones 5 to install bolts to keep the motor body 6 and the fixed seat 1 in a fixed connection state to enhance stability. When the angle of the motor body 6 needs to be adjusted, the bolts on the outer wall of the centering cone 5 can be removed, and the bolts will not affect the angle adjustment (some motors fixedly connected to the output device are less affected by vibration. Therefore, the bolts on the outer wall of the centering cone 5 are not reflected in the present invention and are supplemented here in text form).

[0074] When the angle of the fine-tuning motor body 6 needs to be adjusted, first as Figure 4 、 Figure 5 and Figure 8 shown, the staff can operate the jack 7 to make its telescopic end lift up (the entire adjustment operation from the operation of the jack 7 to the completion of the angle adjustment of the motor body 6 involves the hydraulic work of the jack 7). When the telescopic end of the jack 7 lifts up, the hydraulic oil inside the second hydraulic cylinder 71 will be injected into the oil cavity of the first hydraulic cylinder 2 by the liquid guide pipe 72 through the piston piece. After the oil cavity receives the oil, it will stably connect the hydraulic pressure and push the hydraulic piston 21 upward, as Figure 9As shown, the upwardly lifted hydraulic piston 21 will drive the T-shaped rod at the upper end to gradually penetrate the connecting gasket 22 and slide until the upper end of the hydraulic piston 21 is tightly attached to the friction groove on the lower surface of the connecting gasket 22. Then, the hydraulic piston 21 starts to push the connecting gasket 22 vertically upward, so that the annular piston plate at the upper end of the connecting gasket 22 gradually moves upward and injects the hydraulic oil filled in the annular oil chamber 31 into the hydraulic chamber of the guide cone 5 through the liquid outlet pipe 32 and the hydraulic hose 33 in turn. After receiving the oil, the hydraulic chamber filled with hydraulic oil in the guide cone 5 will gradually push down the piston member 51, so that the piston member 51 gradually compresses the reset spring 53 to fall and gradually pushes the movable ball 52 rotatably connected at the lower end into the annular track 11.

[0075] When the movable ball 52 is tightly attached to the annular track 11, the pilot cone 5 will be slightly lifted up, and when the lower end of the pilot cone 5 is separated from the surface of the fixed seat 1, the connecting gasket 22 rises to the top of the annular oil chamber 31, and then enters the angle adjustment link, the hydraulic pressure continues to occur, the hydraulic piston 21 continues to push up, and the hydraulic piston 21, the connecting gasket 22 and the pilot convex plate 3 have reached the maximum stroke and can no longer move relative to each other. Therefore, the hydraulic piston 21 that continues to push up will directly drive the pilot convex plate 3 to move vertically upward, and Figure 6 and Figure 7 As shown in the figure, when the guiding convex plate 3 moves vertically upward, the inner wall of the guiding groove 34 with a gradually changing width will gradually generate a rotational thrust on the cone wall of the guiding cone 5. At the same time, since the supporting force on the lower end of the guiding cone 5 is replaced by the rolling contact between the movable ball 52 and the annular track 11, the rotational thrusts of the inner walls of the multiple sets of guiding grooves 34 on the multiple sets of guiding cones 5 will cause the guiding cones 5 to drive the supporting seat 4 and the motor body 6 to rotate synchronously. The rotation angle converted from the vertical lift is very precise and easy to control. At the same time, the rolling contact between the movable ball 52 and the annular track 11 can also be used to control the rotation angle of the guiding cone 5. The dynamic coordination makes the small-angle adjustment of the motor body 6 easier and more controllable. At this time, the staff only needs to slowly apply pressure to the jack 7 while observing and judging according to experience (generally, there will be parameter coordination of the coaxial detection equipment, while applying pressure and adjusting, while observing the detection equipment parameters to achieve the best operating angle). The angle that needs to be further adjusted saves time and effort. In addition, the motor body 6 is supported by the movable balls 52 that are evenly distributed at different angles and limited by the annular track 11, so the stability of the motor body 6 is relatively high, and it is only necessary to grasp the angle of the motor body 6 for fine-tuning.

[0076] When the angle of fine adjustment of the motor body 6 is satisfied, the jack 7 is unloaded at this time. When the jack 7 is unloaded, the hydraulic pressure of the entire hydraulic system is released. At the moment when the hydraulic pressure is released, the piston member 51 and the movable ball 52 will lose the ability to support the motor body 6. Therefore, the motor body 6 that is lifted by multiple sets of guiding cones 5 and slightly lifted off the ground will quickly fall under its own gravity to achieve positioning. Due to the release of hydraulic pressure, the pressing force between the hydraulic piston 21 and the guiding convex disk 3 also disappears instantly. When the motor body 6 falls, the downward pressure of the guiding cone 5 will generate a reverse extrusion force on the inner wall of the guiding groove 34, so that the guiding convex disk 3 deflects at a certain angle on the upper end of the hydraulic piston 21, and the deflected angle is the same as the angle adjusted by the motor body 6, so as to achieve the automatic positioning of the motor body 6. Finally, the bolt passes through the bolt seat welded to the outside of the guiding cone 5 mentioned above, and the lower end of the bolt seat is pressed against the fixed seat 1 to lock the motor body 6.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
