Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a motor adjustment seat and a control method thereof. Background Art

[0002] In daily production activities, it is often necessary to use motors as power sources. Some large motors have large power and are used as front-end power sources for equipment or production lines. Generally, a fixed base is required to maintain stability during operation. For example, an adjustable motor base with publication number CN113659766A is used. The motor is fixed in the device, and the base adjustment driving component is used to drive the base adjustment lifting component and the base adjustment rotating component to work. When performing lifting control, the power contact transmission control component is used to control the connection relationship between the lifting adjustment connection component and the base adjustment drive component to achieve lifting or rotation adjustment changes, thereby freely adjusting the height of the motor base and the direction of the motor.

[0003] However, in actual production activities, for medium and large motors, after the initial hoisting, installation and commissioning, the angle and height are generally not adjusted significantly. This is because the motor, as an output source, needs to be stably connected with the production equipment or production line and can only be used after complex commissioning. The rational use of space (angle and height) has already undergone strict commissioning and verification. There is little demand for height adjustment of the motor during the later operation and maintenance of the equipment. Even if height adjustment is required, it is hoisted together with the back-end production equipment to adjust the height. If the motor height is adjusted alone, it will be necessary to conduct complex commissioning and verification again before it can be put into use, just like the initial installation. It is generally not recommended to adjust the height alone.

[0004] At present, for the adjustment of a larger angle (more than 90 degrees), the conventional method is to first rotate the motor to a larger angle by hoisting or the method in the above patented technology, and then make fine adjustments. It is relatively easy to lift the motor by equipment or other existing methods, but it is very difficult to precisely control the motor to remain in place and fine-tune the angle:

[0005] At present, the key and difficulty of motor adjustment lies not in large-angle adjustment, but in angle fine-tuning. The current optimal motor angle adjustment method requires the adjustability of the base on the one hand, and the fine debugging and cooperation of the staff on the other hand. Both are indispensable, because motors are often irregular in shape and can only rely on surface-to-surface contact support to maintain a stable center of gravity. Once a heavy motor leaves the ground, its controllability will become very poor. No matter how sophisticated the angle adjustment equipment is, it will ultimately require the staff to repeatedly compare the front and back end equipment (the deviation angle of the output center) and repeatedly debug to gradually reduce the angle difference and finally achieve a coaxial state.

[0006] To this end, the present invention proposes a high-stability auxiliary motor adjustment seat that switches the support mode through hydraulic assistance and controls the motor angle by utilizing the height change of the guide convex plate. 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 that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a motor adjustment seat and a control method thereof to solve the problem proposed in the above background technology that for the adjustment of larger angles (more than 90 degrees), the conventional method is to first rotate the motor to a larger angle by hoisting or the method in the above patent technology, and then make fine adjustments.

[0013] Preferably, a plurality of liquid outlet pipes are fixedly connected to the upper end of the annular oil chamber at equal angles, and a hydraulic hose is connected to the upper end of the liquid outlet pipe;

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

[0015] Preferably, the interior 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 provided at the center of the guiding cone;

[0016] A connecting pipe is fixedly passed through the upper end of the hydraulic chamber, and the outer end of the connecting pipe is connected with the end of the hydraulic hose.

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

[0018] Preferably, the guiding groove is designed to be an arc with a gradually changing width, and the guiding cone is slidably arranged inside the guiding groove.

[0019] Preferably, the piston and the movable ball, the piston is telescopically and slidably arranged inside the hydraulic chamber, a ball sleeve is fixed to the lower end of the piston, and the movable ball is rotatably arranged inside the ball sleeve;

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

[0021] The lower end of the guiding cone is provided with a retracting groove capable of retracting the movable ball, and the upper surface of the fixing seat is provided with a ring track closely matching with the movable ball.

[0022] Preferably, the hydraulic transmission assembly includes a second hydraulic cylinder and a fluid guide tube, a piston sheet is fixed to the upper end of the telescopic end of the jack, the lower end of the second hydraulic cylinder is open and fixedly connected to the upper end of the jack cylinder body component, and the piston sheet is sealingly and slidably arranged inside the second hydraulic cylinder;

[0023] The upper end of the second hydraulic cylinder is connected to one end of the liquid guiding tube, and the other end of the liquid guiding tube is connected to the oil chamber inside the first hydraulic cylinder.

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

[0025] First stroke: The jack lifts the hydraulic piston hydraulically, and the lifted hydraulic piston will push out the piston inside the pilot cone again by hydraulic drive and lift the pilot cone slightly, realizing the switching of the bottoming mode of the movable ball and the pilot cone;

[0026] Second stroke: The hydraulic piston continues to extend to lift the guide convex plate vertically, and the guide groove inside the guide convex plate is used to realize the rotation drive of the guide cone, forcing the guide cone to drive the motor body to rotate to achieve angle fine-tuning;

[0027] Landing: When the jack output is released, the entire hydraulic system is depressurized, the bottoming mode of the movable ball and the guide cone is switched again, and the motor body is landed at the adjusted angle.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention utilizes the labor-saving lifting of the jack to inject the hydraulic oil in the second hydraulic cylinder into the oil chamber of the first hydraulic cylinder through the liquid guide pipe and lift the hydraulic piston upward, and then push the connecting gasket vertically upward and inject the full hydraulic oil in the annular oil chamber into the hydraulic chamber of the pilot cone through the liquid outlet pipe and the hydraulic hose in sequence, so that the piston member gradually falls, the movable ball connected to the lower end is gradually pushed into the annular track, and the pilot cone is slightly lifted, so as to change the bottoming mode of the pilot cone, and greatly reduce the friction resistance when adjusting the motor angle without losing stability;

[0030] Then the hydraulic pressure continues to occur, and the hydraulic piston that continues to push up will directly drive the guide convex plate to move vertically upward. When the guide convex plate moves vertically upward, the inner wall of the guide groove with a gradually changing width will gradually generate a rotational thrust on the cone wall of the guide cone. At the same time, since the supporting force on the lower end of the guide cone is replaced by the rolling contact between the movable ball and the annular track, the rotational thrust of multiple sets of guide groove inner walls on multiple sets of guide cones will cause the guide cone to drive the supporting seat and the motor body to rotate synchronously. The rotation angle converted from the vertical lift is very precise and easy to control. At the same time, through the rolling cooperation between the movable ball and the annular track This makes small-angle adjustment of the motor body more labor-saving, easy and controllable. At this time, the staff only needs to slowly apply pressure to the jack while judging the angle that needs to be further adjusted based on experience, which saves time and effort. In addition, the motor body is supported by movable balls that are evenly distributed at different angles and limited by a circular track. The motor body has a higher stability. It is only necessary to grasp the angle of the motor body for fine-tuning. The horizontal problem where it is difficult to accurately control the angle is cleverly converted to the vertical problem. In simple terms, the angle is controlled by adjusting the height, which saves effort and is more stable, and is more suitable for the staff to debug the motor angle.

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 11The present invention provides a technical solution: a motor adjustment seat, comprising a fixing seat 1, a motor body 6 installed just above the fixing seat 1, a supporting seat 4 fixedly connected to the lower end of the motor body 6, and a jack 7 fixed to the surface of the fixing seat 1, and also comprising a first hydraulic cylinder 2 fixed to the upper surface of the fixing seat 1 for connecting the jack 7 to output hydraulic pressure, a guide convex plate 3 arranged just above the first hydraulic cylinder 2 for fine-tuning the angle of the motor body 6 based on its own height change, and a plurality of guide cones 5 arranged at equal angles between the guide convex plate 3 and the supporting seat 4 for switching the supporting mode of the motor body 6 by changing the contact mode with the fixing seat 1, a telescopic mechanism connecting the hydraulic output of the first hydraulic cylinder 2 is installed inside the guide 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 disc 3 is used to guide the guiding cone 5 and the lower end of the guiding cone 5 is provided with a movable ball 52 which is adaptively extended when the angle of the motor body 6 is adjusted and converts the fitting and fixed supporting mode of the motor body 6 into a rolling supporting mode.

[0046] As a further embodiment of the present invention, the motor body 6 is fixedly connected to the supporting seat 4 by threads. When the motor body 6 is operating, the first hydraulic cylinder 2 is fixed to the upper surface of the fixing 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 disc 3, the guiding convex disc 3 limits the guiding cone 5 through the guiding groove 34, and the upper end of the guiding cone 5 is fixedly connected to the supporting seat 4, so the limiting of the motor body 6 is indirectly achieved by a fixing part of the first hydraulic cylinder 2, and at the same time, the lower end of the guiding cone 5 is closely attached to the upper surface of the fixing seat 1, so the main support of the motor body 6 is implemented by the guiding cone 5 with equal angles at the lower end. When adjusting the angle, the supporting method of the motor body 6 switches the surface support of the lower end of the guiding cone 5 to the rolling support of the movable ball 52 to reduce the friction resistance when the angle of the motor body 6 is adjusted;

[0047] The hydraulic transmission assembly is used to transmit the labor-saving output of the jack 7 to the inside of the first hydraulic cylinder 2 in the form of hydraulic pressure, and transmit the hydraulic output to the telescopic mechanism inside the guide cone 5 through the first stroke of the hydraulic piston 21 extending, so that the movable ball 52 at the lower end of the piston 51 extends into the fitting annular track 11 and lifts the guide cone 5 slightly. Then, after the first stroke of the hydraulic piston 21 is completed, the hydraulic piston 21 will continue to extend the second stroke, and push the guide convex plate 3 vertically upward 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 is pressed against the inner wall of the annular oil chamber 31, but because the movable ball 52 can effectively reduce rolling friction, the rotational force that drives the guide cone 5 to drive the support seat 4 on which the motor body 6 is installed is smaller than the resistance of the guide groove 34 sliding along the surface of the guide cone 5, and the upward hydraulic driving force of the guide convex plate 3 is greater than the friction resistance and the support seat 4 The gravity above is an obstacle, so the guiding boss 3 mainly moves vertically upward when the hydraulic pressure continues), and when the guiding boss 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 contact between the movable ball 52 and the annular track 11, the rotational thrust of the multiple sets of inner walls of the guiding grooves 34 on the multiple sets of guiding cones 5 will prompt the guiding cone 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, through the rolling cooperation between the movable ball 52 and the annular track 11 and the reduction of the gravity applied by the motor body 6 between the guiding cone 5 and the fixed seat 1, the small angle adjustment of the motor body 6 is more labor-saving, easy and controllable (resulting in a reduction in the gravity applied to the guiding cone 5 and the fixed seat 1, which is a reduction in the shared force rather than a reduction in gravity).

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

[0049] The lower surface of the connection gasket 22 is provided with a friction groove which fits closely with the upper end of the hydraulic piston 21 .

[0050] When hydraulic pressure occurs, the upper end of the hydraulic piston 21 will gradually reach a state of close fit with the friction groove. Under the weight of the heavy motor body 6 on the guide boss 3, the close fit state can be understood as a locked state, which only provides vertical lift for the guide boss 3 and the guide boss 3 cannot rotate.

[0051] As a further embodiment of the present invention, an annular piston plate is fixed to the upper surface of the connecting gasket 22, and an annular oil chamber 31 is opened at the lower end of the guide boss 3 corresponding to the annular piston plate, and the upper end of the annular piston plate is sealed and slidably arranged inside the annular oil chamber 31.

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

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

[0054] The annular oil chamber 31 is slidably matched in the annular oil chamber 31 . When the connecting gasket 22 is forced to move upward, the hydraulic oil inside the annular oil chamber 31 will be stably injected into the interior of the guide cone 5 through the liquid outlet pipe 32 and the hydraulic hose 33 to realize the ejection of the telescopic mechanism inside the guide cone 5 .

[0055] As a further embodiment of the present invention, the interior of the guiding convex disc 3 is provided with guiding grooves 34 corresponding to the number of the guiding cones 5 at equal angles, and a hydraulic cavity is provided at the center of the guiding cone 5;

[0056] A connecting pipe is fixedly passed through the upper end of the hydraulic chamber, and the outer end of the connecting pipe is connected to the end of the hydraulic hose 33 .

[0057] After receiving the hydraulic oil transmitted from the annular oil chamber 31, the hydraulic chamber will push out the piston 51 and the movable ball 52, causing the lower end of the movable ball 52 to fall into the annular track 11 opened on the upper surface of the fixing seat 1, thereby facilitating the subsequent fine adjustment of the angle of the pilot cone 5.

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

[0059] When the angle of the motor body 6 is not adjusted, the support seat 4 can be regarded as a fixed pillar for supporting the motor body 6 by the guide cone 5 distributed at equal angles below. When the angle of the motor body 6 is adjusted, these pillars distributed at equal angles will be transformed into movable pillars that can roll along the circular track 11 under hydraulic assistance.

[0060] As a further embodiment of the present invention, the guiding groove 34 is designed to be arc-shaped with a gradually changing width, and the guiding cone 5 is slidably disposed inside the guiding groove 34 .

[0061] The vertically rising guide boss 3 will drive the guide groove 34 to rise vertically. Since the side wall of the guide cone 5 fits well with the guide groove 34 and the large diameter end of the guide cone 5 faces upward, that is, the guide cone 5 becomes thicker as it goes up. If the guide cone 5 cannot change its angle, the guide groove 34 cannot follow the vertical rise of the guide boss 3. However, the lower end of the guide cone 5 can change its angle and the width of the guide groove 34 is gradual. Therefore, under the vertical resistance of the guide groove 34, the guide cone 5 has to be offset at an angle to meet the vertical rising stroke of the guide groove 34.

[0062] As a further embodiment of the present invention, the telescopic mechanism includes a piston 51 and a movable ball 52, and the piston 51 is telescopically and slidably arranged inside the hydraulic chamber, a ball sleeve is fixed at the lower end of the piston 51, and the movable ball 52 is rotatably arranged inside the ball sleeve;

[0063] A return spring 53 is wound around the outer wall of the piston member 51, and 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] A retracting groove for retracting the movable ball 52 is formed at the lower end of the guiding cone 5 , and a circular track 11 which fits closely with the movable ball 52 is formed on the upper surface of the fixing seat 1 .

[0065] A ball sleeve is fixed to the lower end of the piston 51, and a movable ball 52 is rotatably arranged inside the ball sleeve, which is a prior art and will not be elaborated on here. The return spring 53 is only used to recover the piston 51 when the hydraulic pressure is released and is not used for load bearing.

[0066] As a further embodiment of the present invention, the hydraulic transmission assembly includes a second hydraulic cylinder 71 and a liquid guide tube 72, a piston sheet is fixed to the upper end of the telescopic end of the jack 7, and the upper end of the cylinder body of the jack 7 is fixedly connected to the second hydraulic cylinder 71 with an open lower end, and the piston sheet is sealingly 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 tube 72 , and the other end of the liquid guide tube 72 is connected to the oil chamber inside the first hydraulic cylinder 2 .

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

[0069] A control method for a motor adjustment seat, the control method comprising the following steps:

[0070] First stroke: the jack 7 hydraulically lifts the hydraulic piston 21, and the lifted hydraulic piston 21 will again hydraulically drive the piston 51 inside the pilot cone 5 and lift the pilot cone 5 slightly, so as to switch the bottoming mode of the movable ball 52 and the pilot cone 5 (when adjusting the angle, the support mode of the motor body 6 will switch from the surface support of the lower end of the pilot cone 5 to the rolling support of the movable ball 52, so as to reduce the friction resistance when the angle of the motor body 6 is adjusted);

[0071] Second stroke: the hydraulic piston 21 continues to extend to lift the guide convex plate 3 vertically, and the guide groove 34 inside the guide convex plate 3 is used to realize the rotation drive of the guide cone 5, forcing the guide cone 5 to drive the motor body 6 to rotate to achieve angle fine adjustment;

[0072] Landing: When the output of the jack 7 is released, the entire hydraulic system is depressurized, the bottoming mode of the movable ball 52 and the guide cone 5 is switched again, and the motor body 6 is landed at the adjusted angle.

[0073] Working principle: When using the motor adjustment 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 to the upper surface of the fixing 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 plate 3, the guiding convex plate 3 limits the guiding cone 5 through the guiding groove 34, and the upper end of the guiding cone 5 is fixedly connected to the supporting seat 4, so the first hydraulic cylinder 2 is used as a fixing part to indirectly limit the motor body 6, and the guiding cone The lower end of 5 is in close contact with the upper surface of the fixing seat 1, so the main support of the motor body 6 is implemented by the guide cone 5 with equal angles 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 guide cone 5 to install bolts, so that the motor body 6 and the fixing seat 1 are kept in a fixed connection state to enhance stability. When it is necessary to adjust the angle of the motor body 6, the bolts on the outer wall of the guide 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, so the bolts on the outer wall of the guide cone 5 are not reflected in the present invention, and are supplemented in text form here).

[0074] When it is necessary to fine-tune the angle of the motor body 6, first Figure 4 , Figure 5 and Figure 8 As shown, the staff can lift the telescopic end of the jack 7 by operating the jack 7 (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), and the lifting of the telescopic end of the jack 7 will inject the hydraulic oil inside the second hydraulic cylinder 71 into the oil chamber of the first hydraulic cylinder 2 through the piston plate through the liquid guide tube 72. After the oil chamber is filled with oil, it will stably connect the hydraulic pressure and lift the hydraulic piston 21 upward, as shown in FIG. Fig. 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 fine-tuning angle of the motor body 6 is satisfied, the jack 7 is unloaded at this time. When the jack 7 unloads the force, the hydraulic pressure of the entire hydraulic system is released at the moment the hydraulic pressure is released. The piston member 51 and the movable ball 52 will lose the ability to support the motor body 6 at the moment the hydraulic pressure is released. Therefore, the motor body 6, which is lifted by multiple sets of guide cones 5 and slightly off the ground, will fall quickly under the action of its own gravity to achieve the landing. Due to the release of the hydraulic pressure, the pressing pressure between the hydraulic piston 21 and the guide boss 3 also disappears instantly. When the motor body 6 falls, the downward pressure of the guide cone 5 will generate a reverse extrusion force on the inner wall of the guide groove 34, so that the guide boss 3 is deflected at a certain angle at the upper end of the hydraulic piston 21. The deflection angle is the same as the adjustment angle of the motor body 6, so as to realize the automatic landing of the motor body 6. Finally, the bolts are passed through the bolt seat welded to the outside of the guide cone 5 mentioned in the previous text, and the lower end of the bolt seat is pressed against the fixed seat 1 to achieve the locking of the motor body 6.
