[0047] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0048] The embodiment of the present disclosure provides a stern shaft disassembly and assembly device, Figure 1 This is a top view of the stern shaft disassembly and assembly equipment, see Figure 1 In this embodiment, the stern shaft disassembly and assembly equipment includes at least two longitudinal sliding rails 10, at least two pulley assemblies 20 and at least two clamping assemblies 30.

[0049] The longitudinal slide rails 10 are arranged parallel to each other and spaced apart. The pulley assembly 20 includes a transverse slide rail 210 and at least two slide seats 220. One end of each slide seat 220 is respectively connected to the transverse slide rail 210, and each slide seat 220 is respectively arranged in sequence along the length direction of the transverse slide rail 210. The number of slide seats 220 is consistent with the number of longitudinal slide rails 10. The other end of each slide seat 220 is respectively movably contacted with the corresponding longitudinal slide rail 10. The number of clamping assemblies 30 is consistent with the number of pulley assemblies 20, and each clamping assembly 30 is respectively movably connected to the transverse slide rail 210 of the corresponding pulley assembly 20.

[0050] It is worth noting that the length direction of the longitudinal slide rail 10 is the Y-axis direction, and the length direction of the transverse slide rail 210 is the X-axis direction. In actual use, the stern shaft disassembly and assembly equipment is placed on a flat horizontal foundation, and the Y-axis direction and the X-axis direction are parallel to the horizontal plane.

[0051] The stern shaft disassembly and assembly device provided by the embodiment of the present disclosure can disassemble and assemble the stern shaft 100. In the process of disassembling and assembling the stern shaft 100, firstly, the longitudinal slide rail 10 is placed on a flat horizontal foundation, the position of each clamping assembly 30 on the transverse slide rail 210 is adjusted, and the stern shaft 100 is clamped and fixed by each clamping assembly 30. Then, the clamping assembly 30 of the first part is loosened, and the pulley assembly 20 where the clamping assembly 30 of the second part is located is driven to move, that is, the slide seat 220 drives the transverse slide rail 210 to move along the length direction of the longitudinal slide rail 10, so that the clamping assembly 30 of the second part drives the stern shaft 100 to move along the length direction of the longitudinal slide rail 10. Then, the clamping assembly 30 of the first part is locked, the clamping assembly 30 of the second part is loosened, and the pulley assembly 20 where the clamping assembly 30 of the first part is located is driven to move, that is, the slide seat 220 drives the transverse slide rail 210 to move along the length direction of the longitudinal slide rail 10, so that the clamping assembly 30 of the first part drives the stern shaft 100 to move along the length direction of the longitudinal slide rail 10. By repeatedly and alternately moving the pulley assembly 20 where the clamping assembly 30 of the first part is located and the pulley assembly 20 where the clamping assembly 30 of the second part is located, the stern shaft 100 can be moved, thereby realizing the disassembly and assembly of the stern shaft 100.

[0052] During the process of disassembling and assembling the stern shaft 100 by using the stern shaft disassembling and assembling equipment provided by the embodiment of the present disclosure, there is no need to hoist the stern shaft 100, so that the posture of the stern shaft 100 is easy to adjust, which effectively simplifies the operation process of disassembling and assembling the stern shaft 100, and improves the operation safety and efficiency.

[0053] Continue to see Figure 1 In this embodiment, the transverse slide rail 210 has a slide hole 211, which is close to one end of the transverse slide rail 210. The length direction of the slide hole 211 is consistent with the length direction of the transverse slide rail 210, and one end of a slide seat 220 is movably inserted in the slide hole 211.

[0054] Figure 2 is a schematic diagram of the swing of the transverse slide rail 210, Figure 2 Perspective and Figure 1 Consistent, Figure 2 FIG. 4 shows three different positions of the traverse rail 210 after the traverse rail 210 is swung. For example, Figure 2 In the figure, the sliding hole 211 is close to the left end of the transverse slide rail 210. The slide seat 220 close to the left end of the transverse slide rail 210 moves along the longitudinal slide rail 10, and the slide seat 220 close to the right end of the transverse slide rail 210 remains stationary, so that the left end of the transverse slide rail 210 can swing with the right end of the transverse slide rail 210 as the axis, so that the stern shaft 100 can be centered on the horizontal plane, and the disassembly and assembly of the stern shaft 100 is more flexible.

[0055] Figure 3 This is the front view of the stern shaft disassembly equipment, combined with Figure 3 In this embodiment, the pulley assembly 20 further includes a locking member 230 . The locking member 230 passes through the sliding hole 211 and is inserted into one end of the sliding seat 220 to lock the sliding seat 220 in the sliding hole 211 .

[0056] In the above implementation, the relative position between the slide 220 and the transverse slide 210 can be fixed by the locking member 230. When the transverse slide 210 is swung, the locking member 230 needs to be loosened so that the transverse slide 210 can swing relative to the slide 220. After the transverse slide 210 has swung, the locking member 230 is locked again to fix the relative position between the transverse slide 210 and the slide 220 to avoid unnecessary movement.

[0057] In some examples, the locking member 230 is a bolt, one end of which passes through the sliding hole 211 and is inserted into one end of the sliding seat 220, and the bolt and the sliding seat 220 are threadedly matched. By tightening the bolt, the locking member 230 can be locked, and by loosening the bolt, the locking member 230 can be loosened.

[0058] In other examples, the locking member 230 is a detachable buckle, etc., which is not limited in the present disclosure.

[0059] Continue to see Figure 3 In this embodiment, the slide 220 includes a rail car 221 and a lifting mechanism 222 .

[0060] The fixed end of the lifting mechanism 222 is connected to the rail car 221, and the lifting end of the lifting mechanism 222 is connected to the transverse sliding rail 210. The side of the rail car 221 facing away from the lifting mechanism 222 is in movably contact with the longitudinal sliding rail 10.

[0061] In the above implementation, the rail car 221 can move along the length direction of the longitudinal slide rail 10 , and the lifting mechanism 222 is respectively connected to the rail car 221 and the transverse slide rail 210 , thereby being able to drive the transverse slide rail 210 to move together with the rail car 221 .

[0062] It is worth noting that the lifting direction of the lifting mechanism 222 is the Z-axis direction. In actual use, the stern shaft disassembly and assembly equipment is placed on a flat horizontal foundation, and the Z-axis direction is perpendicular to the horizontal plane. The lifting mechanism 222 can drive the transverse slide rail 210 to rise and fall, so that the stern shaft 100 can be centered in a direction perpendicular to the horizontal plane, and the disassembly and assembly of the stern shaft 100 is more flexible.

[0063] Exemplarily, the lifting mechanism 222 is an oil cylinder, the cylinder body of the oil cylinder serves as the fixed end of the lifting mechanism 222, and the piston rod of the oil cylinder serves as the lifting end of the lifting mechanism 222. By extending and retracting the oil cylinder, the lifting and lowering drive of the transverse slide rail 210 can be realized.

[0064] Exemplarily, the rail vehicle 221 includes a vehicle seat 223 , wheels 224 , and brakes 225 .

[0065] The wheel 224 is rotatably connected to the seat 223 , and the brake member 225 is connected to the seat 223 . The brake member 225 is used to brake the wheel 224 .

[0066] In the above implementation, the seat 223 is the main body of the rail vehicle 221 and mainly plays the role of load-bearing support. The wheel 224 is installed at the bottom of the seat 223 to produce rolling cooperation with the longitudinal slide rail 10. The brake member 225 is used to provide braking force, thereby achieving braking of the rail vehicle 221.

[0067] In some examples, the brake member 225 is a disc brake. In this case, a brake caliper cooperates with a brake disc on the wheel 224 to achieve braking of the wheel 224 .

[0068] In other examples, the brake member 225 is a drum brake or the like, or a simpler combination of a latch and a pin control, which is not limited in the present disclosure.

[0069] Figure 4 is a cross-sectional view of the clamping assembly 30, Figure 4 Perspective and Figure 3 Consistent perspective, combined Figure 4 In this embodiment, the clamping assembly 30 includes a shaft seat 310 , a driving mechanism 320 , a first clamping claw 330 and a second clamping claw 340 .

[0070] One side of the shaft seat 310 has a groove 311, and the first claw 330 and the second claw 340 are respectively located on both sides of the shaft seat 310, and the clamping ends of the first claw 330 and the second claw 340 are respectively located on both sides of the groove 311, and the matching ends of the first claw 330 and the second claw 340 are respectively connected to the driving mechanism 320, and the parts between the two ends of the first claw 330 and the second claw 340 are respectively pivotally connected to the shaft seat 310, and the driving mechanism 320 is used to drive the matching ends of the first claw 330 and the second claw 340 to swing.

[0071] In the above implementation, the groove 311 of the shaft seat 310 is used to accommodate the stern shaft 100. The clamping end and the mating end of the first claw 330 are opposite ends of the length direction of the first claw 330, and the clamping end and the mating end of the second claw 340 are opposite ends of the length direction of the second claw 340. The mating ends of the first claw 330 and the second claw 340 are respectively connected to the driving mechanism 320, so that the first claw 330 and the second claw 340 can rotate around their own pivot axis under the drive of the driving mechanism 320. During the rotation process, if the clamping ends of the first claw 330 and the second claw 340 move toward each other, the stern shaft 100 located in the groove 311 can be clamped and fixed, and if the clamping ends of the first claw 330 and the second claw 340 move away from each other, the stern shaft 100 is loosened.

[0072] Exemplarily, the first clamping claw 330 and the second clamping claw 340 are respectively pivotally connected to the shaft seat 310 through a pin shaft.

[0073] Exemplarily, the clamping ends of the first clamping claw 330 and the second clamping claw 340 are bent toward the groove 311. Such a design can facilitate the first clamping claw 330 and the second clamping claw 340 to clamp the stern shaft 100 in the groove 311.

[0074] Continue to see Figure 4 In this embodiment, the shaft seat 310 has two accommodating grooves 312 , and the two accommodating grooves 312 are respectively located on both sides of the groove 311 , the first claw 330 is located in one accommodating groove 312 , and the second claw 340 is located in the other accommodating groove 312 .

[0075] In the above implementation, the two accommodating grooves 312 are respectively used to accommodate the first claw 330 and the second claw 340, so that the internal space of the shaft seat 310 can be used to accommodate the first claw 330 and the second claw 340, making the structure of the clamping assembly 30 more compact, which is conducive to the miniaturized design of the clamping assembly 30.

[0076] In this embodiment, a through hole 313 is defined in the shaft seat 310 , and two ends of the through hole 313 correspond to the mating ends of the first claw 330 and the second claw 340 , respectively.

[0077] The driving mechanism 320 includes a screw rod 321, a balancing block 322, a first elastic member 323 and a second elastic member 324. The screw rod 321 can axially move through the first clamping claw 330, the through hole 313 and the second clamping claw 340. The first end of the screw rod 321 has an outer flange 325. The portion of the screw rod 321 close to the second end is threadedly engaged with the shaft seat 310. The balancing block 322 is movably sleeved on the outside of the screw rod 321, and the balancing block 322 is movably located in the through hole 313. The first elastic member 323 is located in the through hole 313, and the first elastic member 323 is compressed between the matching ends of the balancing block 322 and the first clamping claw 330. The second elastic member 324 is located in the through hole 313, and the second elastic member 324 is compressed between the matching ends of the balancing block 322 and the second clamping claw 340.

[0078] In the above implementation, although the screw 321 passes through the first claw 330, the through hole 313 and the second claw 340, there is no assembly relationship between the screw 321 and the first claw 330, the through hole 313 and the second claw 340, and the screw 321 can move freely in the first claw 330, the through hole 313 and the second claw 340. The outer flange 325 of the first end of the screw 321 is located on the side of the first claw 330 facing away from the second claw 340, and the outer peripheral wall of the screw 321 near its second end has an external thread, which is located on the side of the second claw 340 facing away from the first claw 330 and inserted into the threaded portion 314 of the shaft seat 310, so that the screw 321 and the shaft seat 310 are threadedly matched. The balancing block 322 is located in the through hole 313 and is sleeved outside the screw rod 321 . There is no assembly relationship between the balancing block 322 , the screw rod 321 and the through hole 313 , and the balancing block 322 can move freely in the through hole 313 .

[0079] The threaded portion 314 is a portion of the shaft seat 310 , and is located on a side of the second clamping jaw 340 facing away from the first clamping jaw 330 .

[0080] In a natural state, the mating ends of the first claw 330 and the second claw 340 are stretched apart by the elastic force of the first elastic member 323 and the second elastic member 324 , so that the clamping ends of the first claw 330 and the second claw 340 are closed to clamp the stern shaft 100 in the groove 311 .

[0081] After the screw 321 is screwed in the first direction, due to the threaded fit between the screw 321 and the shaft seat 310, the screw 321 will move along its own axial direction relative to the shaft seat 310, and the outer flange 325 will move toward the threaded portion 314 accordingly. The outer flange 325 and the threaded portion 314 together squeeze the mating ends of the first claw 330 and the second claw 340, so that the mating ends of the first claw 330 and the second claw 340 gradually close together, and the clamping ends of the first claw 330 and the second claw 340 are gradually stretched open to prevent the stern shaft 100 in the loose groove 311.

[0082] After the screw rod 321 is screwed in the second direction, the screw rod 321 moves in the opposite direction of its own axis relative to the shaft seat 310, and the outer flange 325 moves away from the threaded portion 314. The mating ends of the first claw 330 and the second claw 340 are stretched open again under the elastic force of the first elastic member 323 and the second elastic member 324, so that the clamping ends of the first claw 330 and the second claw 340 are closed again. The first direction and the second direction of screwing the screw rod 321 are opposite directions.

[0083] During the compression or relaxation of the first elastic member 323 and the second elastic member 324, since the balance block 322 is arranged between the first elastic member 323 and the second elastic member 324, the movable balance block 322 can move adaptively according to the elastic force of the first elastic member 323 and the second elastic member 324, so that a dynamic balance state can be reached between the first elastic member 323 and the second elastic member 324, so that the force applied by the first claw 330 and the second claw 340 to the stern shaft 100 remains relatively consistent, thereby avoiding the stern shaft 100 from being skewed due to excessive force deviation.

[0084] Exemplarily, the first elastic member 323 and the second elastic member 324 are coil springs, and the first elastic member 323 and the second elastic member 324 are both sleeved outside the screw rod 321 .

[0085] Continue to see Figure 4 In this embodiment, the driving mechanism 320 further includes a third elastic member 326 and a fourth elastic member 327 .

[0086] The third elastic member 326 is compressed between the outer flange 325 and the mating end of the first claw 330 , and the fourth elastic member 327 is compressed between the inner wall of the shaft seat 310 and the mating end of the second claw 340 .

[0087] The third elastic member 326 and the fourth elastic member 327 are used to play a buffering role. After the screw 321 is screwed along the first direction, the outer flange 325 moves toward the threaded portion 314 along with the screw 321, so that the third elastic member 326 and the fourth elastic member 327 are compressed and the elastic force is transmitted to the mating ends of the first claw 330 and the second claw 340, so that the mating ends of the first claw 330 and the second claw 340 are gradually closed, and the clamping ends of the first claw 330 and the second claw 340 are gradually stretched apart to prevent the stern shaft 100 in the loose groove 311.

[0088] Compared with the outer flange 325 and the threaded portion 314 directly acting on the first claw 330 and the second claw 340 , the third elastic member 326 and the fourth elastic member 327 are used as intermediate force transmission media to effectively protect the first claw 330 and the second claw 340 .

[0089] Exemplarily, the third elastic member 326 and the fourth elastic member 327 are coil springs, and both the third elastic member 326 and the fourth elastic member 327 are sleeved outside the screw rod 321 .

[0090] Exemplarily, the stiffness of the third elastic member 326 and the fourth elastic member 327 is smaller than the stiffness of the first elastic member 323 and the second elastic member 324 .

[0091] With such a design, the first elastic member 323 and the second elastic member 324 mainly play the role of opening the mating ends of the first clamping claw 330 and the second clamping claw 340, and the third elastic member 326 and the fourth elastic member 327 mainly play the role of buffering. On the one hand, it avoids the first clamping claw 330 and the second clamping claw 340 being difficult to loosen due to excessive elastic force, and on the other hand, it also avoids the first clamping claw 330 and the second clamping claw 340 being insufficiently clamped due to insufficient elastic force.
