Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a rudder blade installation tool. Background Art

[0002] In the shipbuilding industry, rudder blades are mostly installed after the shaft rudder system is pulled and illuminated. At this time, the hull structure has been basically installed. The rudder arm of most ship types is far away from the stern rudder board. Due to the line shape of the stern of the hull and the position of the rudder arm, the rudder blade cannot be directly hoisted into place like other hull sections. A special transfer method is needed to transport the rudder blade to the vicinity of the rudder arm for installation.

[0003] When installing the existing smaller and lighter rudder blades, the operator will lift and adjust the rudder blades by means of a hand winch or the like. When adjusting, it is not only necessary to manually connect the rudder blade to the hand winch, but also to adjust the position of the rudder blade by pulling. While pulling, since the hand winch is connected to the rudder blade by an iron chain, it often shakes greatly when it rises, making it difficult to adjust the specific position of the rudder blade, making the device more troublesome to use.

[0004] Therefore, the present invention proposes a rudder blade installation tool to improve this problem. Summary of the invention

[0010] Furthermore, the driving structure comprises:

[0011] A sliding sleeve is slidably mounted on the hydraulic rod, the sliding sleeve is provided with an external thread, the sliding sleeve is threadedly connected with a driving sleeve, and a pulling plate is rotatably mounted on the driving sleeve;

[0012] The hinged long rod is hinged on the pulling plate, the expansion plate is hinged with a hinged secondary rod, the hinged secondary rod is hinged with the rod body of the hinged long rod, a connecting block is installed on the clamping plate, and two mutually hinged short rods are hinged on the connecting block, wherein the free end of one of the hinged short rods is hinged with the free end of the hinged long rod, and the free end of the other hinged short rod is hinged with the rod body of the hinged secondary rod;

[0013] The articulated secondary rod is pressed by the articulated long rod, and the positions of its four corners are changed through the parallelogram structure, thereby pulling the connecting block to slide in the sliding hole along its length and depth directions. During the process, the sliding direction of the splint is restricted by the sliding hole, and the connecting block and the splint are pulled to slide in the sliding hole, so that the splints are close to each other, and the rudder blade is clamped and fixed, thereby increasing the stability of the device in clamping the rudder blade when in use.

[0014] Furthermore, the adjusting component comprises:

[0015] A side plate is mounted on the lifting plate, a slot is provided on the side plate, a rotating sleeve is threadedly connected to the threaded rod, a driving plate is rotatably mounted on the rotating sleeve, the driving plate is used to be inserted in the slot, an insert block is installed in the slot through a connecting spring, and a plug hole for inserting the insert block is provided on the driving plate;

[0016] A bevel gear set, wherein one bevel gear is mounted on a threaded rod, and the other bevel gear is rotatably mounted on a mounting plate, a housing shell is rotatably mounted on the mounting plate, a polygonal block is slidably mounted on the rotating shaft of the bevel gear through a push spring, and the polygonal block is used to be inserted in the housing shell, a transmission rod is rotatably mounted on the mounting plate, a driving gear is slidably mounted on the transmission rod through a driving spring, teeth meshing with the driving gear are mounted on the outer peripheral side of the driving sleeve, a baffle for shielding the driving gear is mounted on the side of the driving sleeve away from the driving spring, and the transmission rod is connected to the housing shell through a pulley assembly;

[0017] Rotate the threaded rod and the supporting plate to insert the polygonal block into the containing shell. At this time, rotate the threaded rod to adjust the position of the clamping plate. When the adjustment is completed, the position of the clamping plate is self-locked through the thread between the driving sleeve and the sliding sleeve. Then rotate the threaded rod and the supporting plate to release the connection between the polygonal block and the containing shell, and rotate the driving plate to connect it with the side plate. At this time, rotate the threaded rod alone to adjust the position of the lifting plate. During the process, the driving plate not only drives the lifting plate, but also supports the side plate through the driving plate when the adjustment stops, and also plays a limiting role, thereby increasing the practicability of the device.

[0018] Furthermore, a sliding rod is installed on the clamping plate, the sliding rod is slidably connected with the sliding hole, a shielding piece is installed on the sliding rod, the shielding piece is located on the side of the expansion panel away from the driving sleeve, and the diameter of the shielding piece is greater than the width of the sliding hole;

[0019] By limiting the shielding plate, the sliding distance of the clamping plate in the direction close to the expansion panel is limited, and then the distance between the clamping plate and the sliding sleeve is limited, so that when the telescopic end of the hydraulic rod slides, the shielding plate is rigidly pushed by the expansion panel to make the sliding sleeve slide, so that the parallelogram structure formed by the articulated short rod, the articulated auxiliary rod and the articulated long rod will not be deformed in advance before clamping the rudder blade, thereby ensuring the feasibility of the device.

[0020] Further, an inclined plate is installed on the lifting plate, a sliding shell for accommodating the inclined plate is provided on the mounting plate, a pushing block is slidably installed on the mounting plate through a resisting spring, a pushing rod is slidably installed on the mounting plate, a wedge-shaped block for being inserted into the sliding shell is installed on the pushing rod, an inclined surface is provided at the bottom of the inclined plate, and the wedge-shaped block is used to support the inclined plate;

[0021] When the threaded rod rotates to the position for adjusting the lifting block, the bearing plate is also rotated, so that the polygonal block pushes the pushing block, and then the pushing block pushes the pushing rod, and then pushes the wedge block to move to the bottom of the inclined plate to support it, so that the inclined plate and the wedge block can support the lifting plate, share the force of bearing the lifting block for the driving block, and further increase the stability of the lifting plate when in use.

[0022] Further, a hanger is installed on the mounting plate, a rotating rod is rotatably installed on the hanger, a connecting rope is wound around the rotating rod, a rubber ring is installed on one end of the connecting rope, the rubber ring is used to be sleeved on the telescopic end of the hydraulic rod, a tightening plate is installed on the other end of the connecting rope, the tightening plate is slidably installed on the hanger, a rotating plate is rotatably installed on the driving sleeve, and a pushing rod for pushing the tightening plate is installed on the rotating plate;

[0023] When the driving sleeve moves away from the expansion panel, it moves towards the hanger, so that the resistance spring resists the tightening plate, and the tightening plate moves away from the expansion panel, and then the connecting rope pulls the rubber ring, causing the rubber ring to deform and lift the telescopic end of the hydraulic rod upward, helping the telescopic end of the hydraulic rod to counteract the gravity of the rudder blade, thereby increasing the stability of the rudder blade when in use.

[0024] Furthermore, a vertical plate is installed on the mounting plate, the vertical plate is rotatably matched with the accommodating shell, a protruding plate is slidably installed on the vertical plate through a push spring, the push spring forces the protruding plate to move away from the vertical plate, and the protruding plate is used to be inserted into the insertion hole;

[0025] When the insertion hole is aligned with the raised plate, it is pushed by the push spring and inserted into the insertion hole, so that the driving plate is connected to the vertical plate, increasing the contact area between the threaded rod and the vertical plate, thereby increasing the stability of the threaded rod when rotating.

[0026] Furthermore, a perforated plate is installed on the rubber ring, the perforated plate is connected to the connecting rope, a square plate is movably installed on the free end of the rubber ring, a locking block is installed on the square plate, and a locking hole for accommodating the locking block is opened on the perforated plate;

[0027] When it is needed to use, the free end of the rubber ring is wound around the outside of the hydraulic rod, the square plate is first slid away from the rubber ring, and then the square plate is rotated to align the locking block with the locking hole, and then the square plate is slid to insert the locking block into the locking hole, so that the rubber ring forms a ring shape, and then the hydraulic rod is wound and fixed, so that the fixing piece fixes the rudder blade and then the rubber ring is connected to the hydraulic rod, so that the hydraulic rod will not rub against the rubber ring when it is contracted, thereby reducing the possibility of excessive wear of the rubber ring during use, and increasing the practicality of the device.

[0028] Furthermore, a limiting hole is provided on the side plate, a guide rod for being inserted into the limiting hole is installed on the insert block, and the connecting spring is sleeved on the outside of the guide rod;

[0029] The guide rod is restricted by the inner wall of the limiting hole, so that the guide rod can only slide in a straight line direction, which increases the stability of the plug when in use, and the connecting spring is also restricted by the outer wall of the guide rod, so that the connecting spring can only be elastically deformed along its axial direction, which also increases the stability of the connecting spring when in use, thereby increasing the practicality of the conductor rod.

[0030] Furthermore, a guide block is installed on the lifting plate, and the push rod slides through the guide block to contact the tightening plate;

[0031] The guide block is penetrated by the resistance rod, so that a hole for limiting the resistance rod is formed thereon, so that the resistance rod can only approach or move away from the tightening plate in a straight line direction, thereby increasing the stability of the resistance rod when in use.

[0032] The beneficial effects of this application are as follows:

[0033] 1. The present application installs a hydraulic rod on the mounting plate. When in use, the threaded rod is connected to the clamping plate by adjusting the component, so that the clamping plate slides on the expansion panel and approaches each other, and the rudder blade is fixed by the clamping plate. After the fixation is completed, the threaded rod is connected to the lifting plate, so that the lifting plate drives the position of the rudder blade to change. During the process, the position of the rudder blade is adjusted by rotating the threaded rod. The adjustment is performed by rotating the threaded rod, so that the displacement of the rudder blade is relatively stable during adjustment, thereby increasing the practicality of the device.

[0034] 2. In the present application, when the driving sleeve moves away from the expansion panel, the pulling plate pulls the articulated long rod to rotate, and at the same time, the articulated sub-rod is pressed by the articulated long rod. At the same time, the positions of the four corners are changed through the parallelogram structure, thereby pulling the connecting block to slide in the sliding hole along its length and depth directions. In the process, the sliding direction of the splint is restricted by the sliding hole, and the connecting block and the splint are pulled to slide in the sliding hole, so that the splints are close to each other, thereby clamping and fixing the rudder blade, thereby increasing the stability of the device in clamping the rudder blade when in use.

[0035] 3. The present application rotates the threaded rod and the supporting plate to insert the polygonal block into the containing shell. At this time, the threaded rod is rotated to adjust the position of the clamping plate. After the adjustment is completed, the position of the clamping plate is self-locked through the thread between the driving sleeve and the sliding sleeve. The threaded rod and the supporting plate are then rotated to release the connection between the polygonal block and the containing shell, and the driving plate is rotated to connect it with the side plate. At this time, the threaded rod is rotated alone to adjust the position of the lifting plate.

[0036] 4. The present application limits the sliding distance of the clamp plate toward the expansion panel through the limitation of the baffle plate, and further limits the distance between the clamp plate and the sliding sleeve, so that when the telescopic end of the hydraulic rod slides, the expansion panel pushes the baffle plate rigidly, causing the sliding sleeve to slide, so that the parallelogram structure formed by the articulated short rod, the articulated auxiliary rod and the articulated long rod will not be deformed in advance before clamping the rudder blade, thereby ensuring the feasibility of the device.

[0037] 5. In the present application, when the threaded rod is rotated to the position for adjusting the lifting block, the bearing plate is also rotated, so that the polygonal block pushes the pushing block, and then the pushing block pushes the pushing rod, and then the wedge block is pushed to move toward the bottom of the inclined plate to support it, so that the inclined plate and the wedge block can support the lifting plate, share the force of bearing the lifting block for the driving block, and further increase the stability of the lifting plate when in use.

[0038] 6. In the present application, when the driving sleeve moves away from the expansion panel, it moves towards the hanger, so that the resistance spring resists the tightening plate, so that the tightening plate moves away from the expansion panel, and then the connecting rope pulls the rubber ring, causing the rubber ring to deform and lift the telescopic end of the hydraulic rod upward, helping the telescopic end of the hydraulic rod to counteract the gravity of the rudder blade, thereby increasing the stability of the rudder blade when in use.

[0039] 7. In the present application, when the insertion hole is aligned with the raised plate, the push spring is used to push the threaded rod into the insertion hole, so that the driving plate is connected to the vertical plate, increasing the contact area between the threaded rod and the vertical plate, thereby increasing the stability of the threaded rod during rotation.

[0040] 8. When the present application needs to be used, the free end of the rubber ring is wound around the outside of the hydraulic rod, the square plate is first slid away from the rubber ring, and then the square plate is rotated to align the locking block with the locking hole, and then the square plate is slid to insert the locking block into the locking hole, so that the rubber ring forms a ring shape, and then the hydraulic rod is wound and fixed, so that the fixing piece fixes the rudder blade and then the rubber ring is connected to the hydraulic rod, so that the hydraulic rod will not rub against the rubber ring when it is contracted, thereby reducing the possibility of excessive wear of the rubber ring during use and increasing the practicality of the device.

[0041] 9. The guide rod of the present application is restricted by the inner wall of the limiting hole, so that the guide rod can only slide in a straight line direction, which increases the stability of the plug during use, and the connecting spring is also restricted by the outer wall of the guide rod, so that the connecting spring can only be elastically deformed along its axial direction, which also increases the stability of the connecting spring during use, thereby increasing the practicality of the wire rod.

[0042] 10. The guide block of the present application is penetrated by the resistance rod, so that a hole is formed thereon to limit the resistance rod, so that the resistance rod can only approach or move away from the tightening plate in a straight line, thereby increasing the stability of the resistance rod when in use.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0059] Embodiment 1

[0060] like Figure 1 - Fig.14 As shown, a rudder blade installation tool proposed in the first embodiment of the present application includes:

[0061] The mounting plate 1 has a hydraulic rod 101 mounted thereon. Figure 1 From the main perspective, the axis of the hydraulic rod 101 is in the horizontal direction, so that its telescopic end is displaced in the horizontal direction;

[0062] A fixing member 2 for fixing the rudder blade is installed on the hydraulic rod 101. The fixing member 2 includes an expansion panel 201. The expansion panel 201 is provided with a plurality of sliding holes 209. A plurality of clamping plates 202 for clamping the rudder blade are slidably installed in the sliding holes 209. A driving structure connected with the clamping plates 202 is installed on the expansion panel 201. The driving structure is used to drive the plurality of clamping plates 202 to approach or move away from each other. When in use, the sliding hole 209 is in the shape of a waist hole. The clamping plates 202 can slide in the sliding hole 209 along the length or depth of the sliding hole 209. The sliding hole 209 is used to limit the sliding of the clamping plates 202. After the rudder blade is installed, the rudder blade is placed between the clamping plates 202, and the clamping plates 202 are slid so that the plurality of clamping plates 202 are close to each other to clamp and fix the rudder blade.

[0063] The lifting member 3 is mounted on the mounting plate 1. The lifting member 3 includes a sliding shell 301. A lifting plate 302 is slidably mounted in the sliding shell 301. The hydraulic rod 101 is mounted on the lifting plate 302. Figure 1 From the main perspective, the lifting plate 302 is used to slide on the sliding shell 301 in the vertical direction;

[0064] An adjusting member 4 is installed on the mounting plate 1. The adjusting member 4 includes a threaded rod 401 and an adjusting component. The threaded rod 401 is rotatably mounted on the mounting plate 1. The adjusting component is used to connect the threaded rod 401 with the lifting plate 302 or the driving structure. When the threaded rod 401 is connected with the driving structure, the threaded rod 401 enables the driving structure to drive the clamping plate 202. When the threaded rod 401 is connected with the lifting plate 302, the threaded rod 401 enables the lifting plate 302 to slide in the sliding shell 301.

[0065] The device is suitable for rudder blades with small volume and light weight, so the ships adapted thereto are also correspondingly small. When adjusting the rudder blade, the adjustment range is small. When the device is used, the threaded rod 401 is first connected to the driving structure through the cooperation of the adjusting component. When it rotates, the clamping plate 202 clamps and fixes the rudder blade through the rotation of the threaded rod 401. After the fixation is completed, the threaded rod 401 is connected to the lifting plate 302 through the cooperation of the adjusting component. At this time, the height of the lifting plate 302 and the rudder blade is adjusted through the rotation of the threaded rod 401. During the process, the rotation of the threaded rod 401 is convenient for the operator to make adjustments. The lifting plate 302 and the threaded rod 401 are made of hard materials. When adjusting, the possibility of excessive shaking of the rudder blade is reduced, further increasing the convenience of the device.

[0066] Compared with the prior art, a hydraulic rod 101 is installed on the mounting plate 1. When in use, the threaded rod 401 is connected to the clamping plate 202 by adjusting the component, so that the clamping plate 202 slides on the expansion panel 201 and approaches each other, and the rudder blade is fixed by the clamping plate 202. After the fixation is completed, the threaded rod 401 is connected to the lifting plate 302, so that the lifting plate 302 drives the position of the rudder blade to change. During the process, the position of the rudder blade is adjusted by rotating the threaded rod 401. The adjustment is performed by rotating the threaded rod 401, so that the displacement of the rudder blade during adjustment is relatively stable, thereby increasing the practicality of the device.

[0067] Embodiment 2

[0068] like Figure 2 and Figure 5 As shown, the second embodiment further discloses the driving structure, the adjusting component, the clamping plate 202 and the lifting plate 302 on the basis of the first embodiment. In the second embodiment, the driving structure includes:

[0069] The sliding sleeve 203 is slidably mounted on the hydraulic rod 101 to Figure 1 From the main perspective, the sliding sleeve 203 is slidably installed on the fixed end of the hydraulic rod 101 along the horizontal direction. The sliding sleeve 203 is provided with an external thread, and the sliding sleeve 203 is threadedly connected with a driving sleeve 204. The driving sleeve 204 is rotatably installed with a pulling plate 205. The driving sleeve 204 changes its position in the horizontal direction on the sliding sleeve 203 by the direction of rotation. Since the driving sleeve 204 is rotatably connected with the pulling plate 205, when the driving sleeve 204 rotates, there will be no relative rotation between the pulling plate 205 and the expansion panel 201.

[0070] The hinged long rod 206 is hinged on the pulling plate 205. The expansion panel 201 is hinged with a hinged secondary rod 207, which is hinged to the rod body of the hinged long rod 206. The clamping plate 202 is equipped with a connecting block 2012, and two mutually hinged short rods 208 are hinged on the connecting block 2012, wherein the free end of one of the hinged short rods 208 is hinged to the free end of the hinged long rod 206, and the free end of the other hinged short rod 208 is hinged to the rod body of the hinged secondary rod 207. A parallelogram structure is formed between the hinged short rod 208, the hinged secondary rod 207 and the hinged long rod 206, and the connecting block 2012 is hinged to a corner of the parallelogram to form the structure of the umbrella skeleton. The hinged long rod 206 is hinged to the pulling plate 205.

[0071] When the pulling plate 205 moves away from the expansion plate 201 along with the driving sleeve 204, the articulated long rod 206 is pulled to rotate, and the articulated secondary rod 207 is pressed by the articulated long rod 206. At the same time, the positions of the four corners are changed by the parallelogram structure, thereby pulling the connecting block 2012 to slide in the sliding hole 209 along its length direction and depth direction. In the process, the sliding hole 209 limits the sliding direction of the clamping plate 202, and also pulls the connecting block 2012 and the clamping plate 202 to slide in the sliding hole 209, so that the clamping plates 202 are close to each other, thereby clamping and fixing the rudder blade, thereby increasing the stability of the device in clamping the rudder blade when in use;

[0072] Among them, the articulated short rod 208, the articulated sub-rod 207 and the articulated long rod 206 are all made of iron sheets or other elastic materials, so that when in use, they can be compatible with the movement amplitude through elastic deformation, thereby increasing the feasibility of the device. During the process, the maximum distance between the three is limited. When in use, the sliding of the sliding sleeve 203 is used to meet the distance of the telescopic end of the hydraulic rod 101. When the telescopic end of the hydraulic rod 101 is away from the lifting plate 302, the sliding sleeve 203 will be pulled to slide first, instead of pulling the parallelogram structure formed by the articulated short rod 208, the articulated sub-rod 207 and the articulated long rod 206 to deform, so as to facilitate the subsequent clamping of the rudder blade by the clamping plate 202.

[0073] like Figure 3 , Figure 4 , Figure 8 , Fig. 9 and Fig.10 As shown, in the second embodiment, the adjusting component includes:

[0074] The side plate 402 is mounted on the lifting plate 302. A slot 403 is provided on the side plate 402. A rotating sleeve 404 is threadedly connected to the threaded rod 401. A driving plate 405 is rotatably installed on the rotating sleeve 404 through a bearing. The driving plate 405 is used to be inserted into the slot 403. An insert block 407 is installed in the slot 403 through a connecting spring 406. A plug hole 408 for inserting the insert block 407 is provided on the driving plate 405. When in use, when the threaded rod 401 rotates, the rotating sleeve 404 is driven to move through the threaded fit to change its position in the vertical direction. Since the driving plate 405 and the rotating sleeve 404 are rotatably matched, the driving plate 405 can also rotate independently after the rotating sleeve 404 is adjusted.

[0075] When adjusting, the driving plate 405 is rotated to be inserted into the slot 403. Since the end of the plug block 407 has a rounded corner, the connecting spring 406 is compressed by the guidance of the arc surface. When the driving plate 405 is rotated until the plug hole 408 is aligned with the plug block 407, the connecting spring 406 pushes the plug block 407 to be inserted into the plug hole 408, thereby limiting the tendency of the driving plate 405 to separate from the slot 403. At this time, when the threaded rod 401 drives the rotating sleeve 404 to change its position, the contact of the driving plate 405 with the inner wall of the slot 403 also drives the side plate 402 and the lifting plate 302 to change their positions in the vertical direction, thereby adjusting the position of the rudder blade.

[0076] During the process, when the driving plate 405 is connected to the side plate 402 through the slot 403, it is equivalent to connecting the driving plate 405 to the lifting plate 302. The sliding direction of the lifting plate 302 is restricted by the sliding shell 301, and the driving plate 405 is also restricted, so that the free end of the driving plate 405 will not rotate around the threaded rod 401, and the lifting plate 302 can be driven smoothly, which increases the feasibility of the device;

[0077] A bevel gear set 409, wherein one bevel gear is mounted on the threaded rod 401, and the other bevel gear is rotatably mounted on the mounting plate 1, a bearing plate 24 is mounted on the mounting plate 1, the bevel gear is rotatably mounted on the bearing plate 24, an annular groove is provided on the mounting plate 1, the axis of the groove is colinear with the axis of the threaded rod 401, the bearing plate 24 is slidably matched with the groove, so that the bearing plate 24 can perform a circular motion around the circumference of the threaded rod 401;

[0078] A containing shell 4010 is rotatably installed on the mounting plate 1, a plate body is installed on the mounting plate 1, the containing shell 4010 is rotatably connected to the plate body, a polygonal block 4012 is slidably installed on the bevel gear shaft through a push spring 4011, a cavity is provided on the bevel gear shaft, the push spring 4011 is located in the cavity, the bevel gear shaft and the bearing plate 24 are rotatably matched, so that the polygonal block 4012 can rotate and slide on the bearing plate 24, the polygonal block 4012 is used to be inserted in the containing shell 4010, and a channel for accommodating the polygonal block 4012 is provided on the containing shell 4010. When in use, by rotating the driving plate 405, the plug-in block 407 and the inner wall of the plug-in hole 408 are in conflict with each other through the guidance of the arc surface, so that it is gradually inserted into the plug-in hole 408. The hole 408 is separated, and then the driving plate 405 is separated from the slot 403, and then the threaded rod 401 and the bearing plate 24 are rotated to drive the polygonal block 4012 to move toward the accommodating shell 4010. The polygonal block 4012 and the side wall of the accommodating shell 4010 are both provided with inclined surfaces. When the two are in conflict, the polygonal block 4012 is inserted into the channel of the accommodating shell 4010 through the guidance of the inclined surface. During the process, the driving plate 405 and the side plate 402 are disconnected and the limit is lost. At this time, the rotation of the threaded rod 401 will not change its position in the vertical direction, which improves the feasibility of the device. At this time, when the threaded rod 401 rotates, it is driven by the bevel gear set 409, so that the rotation of the polygonal block 4012 can drive the accommodating shell 4010 to rotate;

[0079] A transmission rod 4015 is rotatably mounted on the mounting plate 1, a driving gear 4013 is slidably mounted on the transmission rod 4015 via a driving spring 4016, teeth 4014 meshing with the driving gear 4013 are mounted on the outer peripheral side of the driving sleeve 204, a baffle 4017 for shielding the driving gear 4013 is mounted on the side of the driving sleeve 204 away from the driving spring 4016, the transmission rod 4015 is connected to the accommodating shell 4010 via a pulley assembly, and the pulley assembly includes two pulleys and a belt, one of which is a belt. The pulley is connected to the transmission rod 4015, and the other is connected to the accommodating shell 4010. The belt is used to connect the two pulleys in a transmission manner, so that when the accommodating shell 4010 rotates, the transmission rod 4015 is also driven to rotate through the transmission of the pulley assembly. A notch is provided on the driving gear 4013, and a block is installed on the transmission rod 4015 to slide with the notch, so that the driving gear 4013 can only slide on it and cannot rotate relatively, so that when the transmission rod 4015 rotates, the driving gear 4013 is driven to rotate;

[0080] When the driving sleeve 204 is displaced on the sliding sleeve 203 through threaded engagement, the driving gear 4013 is pushed by the driving spring 4016 to slide on the transmission rod 4015, so that the driving gear 4013 and the teeth 4014 are always kept in meshing. During the process, the distance that the driving gear 4013 is pushed by the driving spring 4016 is limited by the baffle 4017, so that the driving gear 4013 will not be pushed to the point of being disengaged from the teeth 4014, thereby increasing the feasibility of the device;

[0081] When in use, first rotate the threaded rod 401 and the bearing plate 24 so that the polygonal block 4012 is inserted into the accommodating shell 4010, then rotate the threaded rod 401 to adjust the position of the clamping plate 202. After the adjustment is completed, the position of the clamping plate 202 is self-locked by the thread between the driving sleeve 204 and the sliding sleeve 203, then rotate the threaded rod 401 and the bearing plate 24 to release the connection between the polygonal block 4012 and the accommodating shell 4010, and rotate the driving plate 405 to connect it with the side plate 402, then rotate the threaded rod 401 alone to adjust the position of the lifting plate 302;

[0082] During the process, the driving plate 405 not only drives the lifting plate 302, but also serves as a limiter by supporting the side plate 402 through the driving plate 405 when the adjustment is stopped, thereby increasing the practicality of the device.

[0083] like Figure 2 and Figure 5 As shown in the second embodiment, a sliding rod 2010 is installed on the clamping plate 202, and the sliding rod 2010 is slidably connected with the sliding hole 209. A shielding piece 2011 is installed on the sliding rod 2010, and the shielding piece 2011 is located on the side of the expansion panel 201 away from the driving sleeve 204. The diameter of the shielding piece 2011 is greater than the width of the sliding hole 209. When in use, the sliding rod 2010 and the sliding hole 209 are slidably matched, and the contact area between the clamping plate 202 and the sliding hole 209 is reduced by the arc surface of the rod body, thereby reducing the friction between the two, thereby facilitating the clamping plate 202 The baffle plate 2011 is used to limit the sliding distance of the clamp plate 202 in the direction of approaching the expansion panel 201, thereby limiting the distance between the clamp plate 202 and the sliding sleeve 203. When the telescopic end of the hydraulic rod 101 slides, the baffle plate 2011 is rigidly pushed by the expansion panel 201, so that the sliding sleeve 203 slides first, and the parallelogram structure formed by the articulated short rod 208, the articulated auxiliary rod 207 and the articulated long rod 206 will not be deformed in advance before the rudder blade is clamped, thereby ensuring the feasibility of the device.

[0084] like Figure 7 and Fig.11As shown, in the second embodiment, the lifting plate 302 is mounted with an inclined plate 5, the mounting plate 1 is provided with a sliding shell 6 for accommodating the inclined plate 5, the mounting plate 1 is slidably mounted with a push block 8 through a resisting spring 7, the mounting plate 1 is mounted with a plate body, the push block 8 is slidably mounted on the plate body, the resisting spring 7 forces the push block 8 to move away from the plate body and approach the threaded rod 401, the push spring 4011 forces the polygonal block 4012 to move away from the threaded rod 401, and when the bearing plate 24 rotates to the point where the polygonal block 4012 is separated from the accommodating shell 4010, the polygonal block 4012 and the push block 8 are rotated to the point where the polygonal block 4012 and the push block 8 are separated. When aligning, the polygonal block 4012 pushes the push block 8 against the push block 8, and the elastic coefficient of the push spring 4011 is greater than the elastic coefficient of the push spring 7, ensuring that the polygonal block 4012 can push the push block 8, and when the polygonal block 4012 pushes the push block 8, the side of the push block 8 facing the polygonal block 4012 is a smooth plane, and the two only conflict with each other through the surface. At this time, the polygonal block 4012 can still rotate, and thus will not affect the rotation of the threaded rod 401 by affecting the rotation of the polygonal block 4012 and the bevel gear set 409;

[0085] A push rod 9 is slidably mounted on the mounting plate 1, and a wedge block 10 for inserting into the sliding shell 6 is mounted on the push rod 9. An inclined surface is provided at the bottom of the inclined plate 5, and the wedge block 10 is used to support the inclined plate 5. The shapes of the inclined plate 5 and the wedge block 10 are as shown in FIG. Fig.11 As shown;

[0086] When in use, when the threaded rod 401 rotates to the position for adjusting the lifting plate 302, the bearing plate 24 is also rotated, so that the polygonal block 4012 pushes the pushing block 8, and then the pushing block 8 pushes the pushing rod 9, and then the wedge block 10 is pushed to gradually move toward the bottom of the inclined plate 5 to support it, so that the inclined plate 5 and the wedge block 10 can support the lifting plate 302, and the driving plate 405 shares the force of carrying the lifting plate 302, further increasing the stability of the lifting plate 302 when in use;

[0087] During adjustment, when the lifting plate 302 gradually rises and has not reached the highest position, the pushing spring 4011 is also in a compressed state. As the inclined plate 5 gradually rises, the wedge block 10 is gradually pushed to the bottom of the inclined plate 5 by gradually resetting the pushing spring 4011. During the process, the wedge block 10 is always in contact with the bottom of the inclined plate 5, thereby increasing the feasibility of the device.

[0088] When the lifting plate 302 needs to be lowered, first rotate the supporting plate 24 to release the interference between the polygonal block 4012 and the pushing block 8, and reset it through the interference spring 7 to facilitate the next push, then slide the pushing rod 9 away from the sliding shell 6 to release the connection between the wedge block 10 and the inclined plate 5, or directly push the pushing block 8 to provide a position for the sliding of the pushing rod 9, and then slide the pushing rod 9 to achieve the effect of releasing the connection between the wedge block 10 and the inclined plate 5, and then rotate the threaded rod 401 to reset the lifting plate 302.

[0089] Embodiment 3

[0090] like Figure 1 - Fig.14 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a hanger 11 is installed on the mounting plate 1, a rotating rod 12 is rotatably installed on the hanger 11, a connecting rope 13 is wound around the rotating rod 12, and the rotating rod 12 acts as a fixed pulley for guiding the connecting rope 13;

[0091] A rubber ring 15 is installed on one end of the connecting rope 13, and the rubber ring 15 is used to be sleeved on the telescopic end of the hydraulic rod 101. The connecting rope 13 is connected to the highest point of the rubber ring 15. A tightening plate 16 is installed on the other end of the connecting rope 13. The tightening plate 16 is slidably installed on the hanger 11. A rotating plate 17 is rotatably installed on the driving sleeve 204, and a resistance rod 18 for pushing the tightening plate 16 is installed on the rotating plate 17. Since the driving sleeve 204 and the rotating plate 17 are rotatably matched, when the driving sleeve 204 rotates, the resistance rod 18 and the tightening plate 16 are in an aligned state. A disc is installed at the end of the resistance rod 18, so that when the lifting plate 302 moves in the vertical direction, the resistance rod 18 can also be aligned with the tightening plate 16, which increases the feasibility of the device;

[0092] When the driving sleeve 204 moves away from the expansion panel 201, it moves towards the hanger 11, so that the resistance rod 18 resists the tightening plate 16, and the tightening plate 16 moves away from the expansion panel 201, so that the connecting rope 13 pulls the rubber ring 15, so that the rubber ring 15 is deformed and the telescopic end of the hydraulic rod 101 is lifted upward, which helps the telescopic end of the hydraulic rod 101 to counteract the gravity of the rudder blade, thereby increasing the stability of the rudder blade when in use.

[0093] In the third embodiment, a vertical plate 19 is mounted on the mounting plate 1, and the vertical plate 19 is rotatably matched with the accommodating shell 4010. A protruding plate 21 is slidably mounted on the vertical plate 19 through a push spring 20. The protruding plate 21 has inclined surfaces on both sides. The push spring 20 forces the protruding plate 21 to move away from the vertical plate 19. The protruding plate 21 is used to be inserted into the insertion hole 408 to Figure 1From the main perspective, the raised plate 21 is slidably installed on the vertical plate 19 along the vertical direction. When the supporting plate 24 and the threaded rod 401 are rotated to connect the polygonal block 4012 with the accommodating shell 4010, the driving plate 405 is rotated so that its surface presses the raised plate 21. When the socket 408 is aligned with the raised plate 21, it is pushed by the pushing spring 20 and inserted into the socket 408, so that the driving plate 405 is connected to the vertical plate 19, thereby increasing the contact area between the threaded rod 401 and the vertical plate 19, thereby increasing the stability of the threaded rod 401 during rotation.

[0094] In the third embodiment, a perforated plate 1501 is installed on the rubber ring 15, and the perforated plate 1501 is connected to the connecting rope 13. A square plate 1502 is movably installed on the free end of the rubber ring 15, and the square plate 1502 can slide and rotate on the rubber ring 15. A locking block 1503 is installed on the square plate 1502, and a locking hole 1504 for accommodating the locking block 1503 is opened on the perforated plate 1501. The rubber ring 15 is strip-shaped in a normal state;

[0095] When it is needed to use, the free end of the rubber ring 15 is wound around the outside of the hydraulic rod 101, the square plate 1502 is first slid away from the rubber ring 15, and then the square plate 1502 is rotated to align the locking block 1503 with the locking hole 1504, and then the square plate 1502 is slid to insert the locking block 1503 into the locking hole 1504, so that the rubber ring 15 forms a ring shape, and then the hydraulic rod 101 is wound and fixed, so that the fixing member 2 fixes the rudder blade and then the rubber ring 15 is connected to the hydraulic rod 101, so that the hydraulic rod 101 will not rub against the rubber ring 15 when it is contracted, thereby reducing the possibility of excessive wear of the rubber ring 15 during use, and increasing the practicality of the device;

[0096] When the rubber ring 15 is pulled by the connecting rope 13 , the locking hole 1504 will be deformed and the locking block 1503 will be stuck, which reduces the possibility of separation of the two and increases the stability of the rubber ring 15 when in use.

[0097] In the third embodiment, a limiting hole 22 is provided on the side plate 402, a guide rod 23 for being inserted into the limiting hole 22 is installed on the insert block 407, and a connecting spring 406 is sleeved on the outside of the guide rod 23;

[0098] The guide rod 23 is restricted by the inner wall of the limiting hole 22, so that the guide rod 23 can only slide in a straight line direction, which increases the stability of the plug block 407 when in use, and the connecting spring 406 is also restricted by the outer wall of the guide rod 23, so that the connecting spring 406 can only be elastically deformed along its axial direction, which also increases the stability of the connecting spring 406 when in use, thereby increasing the practicality of the guide rod 23.

[0099] In embodiment three, a guide block 14 is installed on the lifting plate 302, and the resistance rod 18 slides through the guide block 14 and resists the tightening plate 16. The guide block 14 is penetrated by the resistance rod 18, so that a hole is formed thereon to limit the resistance rod 18, so that the resistance rod 18 can only approach or move away from the tightening plate 16 in a straight line direction, thereby increasing the stability of the resistance rod 18 when in use.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
