Description

Technical Field

[0001] This invention relates to the field of buoy clamping technology, and in particular to a switchable hydraulic pump station buoy clamping device. Background Technology

[0002] Conventional buoy clamping devices are installed at the bow to hold the buoy, which is rigidly connected to the hull. A flipping device allows the buoy to be flipped onto the bow deck for further inspection and maintenance. The placement of the buoy clamping device places high demands on the deck layout and requires appropriate modifications to the bow line design. This type of buoy clamping device can only hold conventional buoys. Conventional buoys have cylindrical floats, while ice-age buoys have conical floats. Due to the different float shapes, conventional clamping devices cannot securely hold ice-age buoys, further hindering buoy inspection, maintenance, and repair.

[0003] In existing technologies, the clamping arm is mainly driven by a clamping cylinder to move in a circular motion around the hinge axis, thereby opening and closing the boom to clamp the buoy. However, the two clamping arms on the existing clamping device do not move horizontally. When clamping buoys of different sizes, the second arc surface of the inner wall of the clamping arm is difficult to fully contact the outer wall of the buoy's circumference, resulting in insufficient contact area between the clamping arm and the buoy, which leads to insufficient friction and insufficient stability during clamping. To address this, we propose a switchable hydraulic pump station buoy clamping device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that, in the prior art, when the clamping arm clamps buoys of different sizes, the second arc surface of the inner wall of the clamping arm is difficult to make sufficient contact with the outer wall of the buoy's circumference, resulting in insufficient contact surface between the clamping arm and the buoy, which leads to insufficient friction and insufficient stability during clamping.

[0011] As a preferred embodiment of the switchable hydraulic pump station buoy clamping device of the present invention, one end of the torsion spring is fixedly connected to the end cover, and the other end of the torsion spring is fixedly connected to the rotating head.

[0012] As a preferred embodiment of the switchable hydraulic pump station buoy clamping device of the present invention, the clamping assembly includes a mounting plate, an extension rod fixedly connected to the outer wall of the mounting plate, the outer ends of the extension rod being hinged to the inner wall of a baffle, two clamping plates fixedly connected to the outer wall of the mounting plate, the two clamping plates being respectively clamped to a toothed plate, a fixing seat provided between the two clamping plates, support plates fixedly connected to the top and bottom of the fixing seat, the ends of the two support plates being respectively connected and fixed to a clamping arm, extension blocks fixedly connected to both sides of the fixing seat, sliding holes provided on the outer walls of the two clamping plates, connecting rods fixedly connected to the inner walls of the two sliding holes, and third springs sleeved on the outer circumferential walls of the two connecting rods. The ends of the extension blocks extend into the sliding holes and are slidably connected thereto. The ends of the two connecting rods pass through the extension blocks and are slidably connected thereto. The inner ends of the two clamping plates are provided with grooves. The inner walls of the grooves are engaged with the side walls of the toothed plates. The inner walls of the fixing base are slidably connected to a stop rod. The outer ends of the stop rods are fixedly connected to a limit ring. The inner ends of the stop rods are fixedly connected to a clamping block. The outer circumference of the stop rods is fitted with a second spring. The outer walls of the clamping block are fixedly connected to two sliding rods. The ends of the two sliding rods pass through the fixing base and are slidably connected thereto. One side of the end of the clamping block is provided with a second arc surface. The other side of the end of the clamping block is provided with a first arc surface. The inner walls of the first and second arc surfaces are slidably in contact with the side walls of the toothed plates.

[0013] In a preferred embodiment of the switchable hydraulic pump station buoy clamping device of the present invention, one end of the third spring is fixedly connected to the inner wall of the sliding hole, and the other end of the third spring is fixedly connected to the extension block.

[0014] In a preferred embodiment of the switchable hydraulic pump station buoy clamping device of the present invention, one end of the second spring is connected and fixed to the fixed base, and the other end of the second spring is connected and fixed to the locking block.

[0015] The beneficial effects of the present invention are as follows: the two sliding blocks move synchronously, which can drive the two clamping arms to move, so that multiple pressure blocks on the inner side of the two clamping arms can squeeze the outer wall of the buoy. The multiple pressure blocks drive the rotating block to rotate around the rotating rod as the center, and the angle of the multiple pressure blocks can be adjusted so that the pads on the inner wall of the multiple pressure blocks can fully contact the outer wall of the buoy, increase the contact area, improve the friction, and make the clamping more stable.

[0016] Depending on the size of the buoy, multiple pressure blocks will push the support rods to slide outward along the bushing by different distances. The first springs on the multiple support rods are compressed according to the size of the buoy. When the multiple support rods slide, they will drive the sliders to slide along the inner wall of the guide groove in the bushing. The multiple support rods will simultaneously drive the toothed plate to move. At this time, the outer protrusions of the toothed plate will squeeze the second arc surface on the locking block. The locking block will slide towards the side of the fixed seat and continuously adjust the locking on the toothed plate. When the locking block moves, it can drive the abutment rod and the slide rod to slide along the inner wall of the fixed seat, compressing the second spring, so that the inner walls of the multiple pressure blocks are in full contact with the outer wall of the buoy.

[0017] The drive assembly can move multiple extension rods on the two clamping arms. When the extension rods move, they can move two clamping plates through the mounting plate, causing the two clamping plates to slide along the extension blocks. At this time, the third spring is compressed until the clamping plates are locked onto the toothed plates. The two clamping plates can then be locked onto the protruding teeth on both sides of the clamping block, thereby fixing the toothed plates and preventing the support rods from sliding. This allows for adjustment of the curvature formed by the combination of multiple pressure blocks in the two clamping arms to adapt to the outer wall curvature of buoys of different sizes.

[0044] Two electric push rods 301 push the baffles 302 to move, so that the slide plates 303 on the two baffles 302 can slide along the inner wall of the moving groove 305 on the arc plate 304.

[0045] Example 5

[0046] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that:

[0047] Please refer to Figures 5-10 The clamping assembly 4 includes a clamping arm 401. The outer wall of the clamping arm 401 is connected and fixed to the electric push rod 301 and two arc plates 304 respectively. The end of the clamping arm 401 is connected and fixed to the slide block 203. The inner wall of the clamping arm 401 is arc-shaped and evenly spaced with multiple bushings 402. Each bushing 402 has two guide grooves 403 on its inner wall. Each bushing 402 has a support rod 404 that slides through it. Each support rod 404 has two sliders 405 fixedly connected to its outer circumference. The ends of the sliders 405 extend into the guide grooves 403 and slide in contact with their inner walls. Each support rod 404 has a toothed plate 413 fixedly connected to its inner wall. Each support rod 404 has a first spring 406 sleeved on its inner end. One end of the first spring 406 is connected to the rotating head 407. The first spring 406 is fixed at one end and connected to the inner wall of the clamping arm 401. The inner ends of the multiple support rods 404 are all fixedly connected to rotating heads 407. The inner walls of the multiple rotating heads 407 are all rotatably connected to rotating rods 408. The two ends of the multiple rotating rods 408 are respectively fixedly connected to end caps 409. The two ends of the multiple rotating rods 408 are respectively fitted with torsion springs 410. One end of the torsion spring 410 is fixedly connected to the end cap 409, and the other end of the torsion spring 410 is fixedly connected to the rotating head 407. The outer circumference of the multiple rotating rods 408 is fixedly connected to rotating blocks 411. The ends of the multiple rotating blocks 411 are all fixedly connected to pressure blocks 412. The inner side walls of the multiple pressure blocks 412 are all equipped with arc-shaped pads. The outer side wall of the clamping arm 401 is equipped with multiple snap-fit ​​components. The multiple snap-fit ​​components are respectively connected to multiple toothed plates 413.

[0048] The snap-fit ​​assembly includes a mounting plate 414, with an extension rod 415 fixedly connected to the outer wall of the mounting plate 414. The outer ends of the extension rod 415 are hinged to the inner wall of the baffle 302. Two snap-fit ​​plates 417 are fixedly connected to the outer wall of the mounting plate 414, and the two snap-fit ​​plates 417 are respectively engaged with the toothed plate 413. A fixing seat 418 is provided between the two snap-fit ​​plates 417. Support plates 416 are fixedly connected to the top and bottom of the fixing seat 418. The ends of the two support plates 416 are respectively connected to the clamping arm 401. For fixing, extension blocks 419 are fixedly connected to both sides of the fixing base 418. Sliding holes 428 are opened on the outer walls of both clamping plates 417. Connecting rods 429 are fixedly connected to the inner walls of both sliding holes 428. Third springs 430 are sleeved on the outer circumference of both connecting rods 429. One end of the third spring 430 is fixedly connected to the inner wall of the sliding hole 428, and the other end is fixedly connected to the extension block 419. The ends of the two extension blocks 419 extend into the sliding holes 428 and... Its sliding connection includes two connecting rods 429, both of which pass through and are slidably connected to the extension block 419. The inner ends of both clamping plates 417 are provided with grooves 427, the inner walls of which are engaged with the side walls of the toothed plates 413. A stop rod 420 is slidably connected through the inner wall of the fixing base 418. A limit ring 421 is fixedly connected to the outer end of the stop rod 420, and a clamping block 423 is fixedly connected to the inner end of the stop rod 420. A second spring 422 is sleeved on the outer circumference of the stop rod 420. One end of the second spring 422 is connected and fixed to the fixed base 418, and the other end of the second spring 422 is connected and fixed to the locking block 423. Two sliding rods 424 are fixedly connected to the outer wall of the locking block 423. The ends of the two sliding rods 424 pass through the fixed base 418 and are slidably connected to it. A second arc surface 426 is provided on one side of the end of the locking block 423, and a first arc surface 425 is provided on the other side of the end of the locking block 423. The inner walls of the first arc surface 425 and the second arc surface 426 are slidably in contact with the side wall of the toothed plate 413.

[0049] The two sliding blocks 203 move synchronously, which can drive the two clamping arms 401 to move, so that the multiple pressure blocks 412 on the inner side of the two clamping arms 401 press against the outer wall of the buoy. The multiple pressure blocks 412 drive the rotating block 411 to rotate around the rotating rod 408 as the center, and adjust the angle of the multiple pressure blocks 412 so that the pads on the inner wall of the multiple pressure blocks 412 can fully contact the outer wall of the buoy, increase the contact area and improve the friction. According to the size of the buoy, the multiple pressure blocks 412 will push the support rod 404 to slide outward along the bushing 402 a different distance. The first spring 406 on the multiple support rods 404 is compressed according to the size of the buoy. When the multiple support rods 404 slide, they will drive the slider 405 to slide along the inner wall of the guide groove 403 in the bushing 402.

[0050] Multiple support rods 404 simultaneously drive the toothed plate 413 to move. At this time, the external protrusions of the toothed plate 413 press against the second arc surface 426 on the locking block 423. The locking block 423 slides towards the side closer to the fixed seat 418, continuously adjusting the locking on the toothed plate 413. When the locking block 423 moves, it can drive the abutment rod 420 and the slide rod 424 to slide along the inner wall of the fixed seat 418, compressing the second spring 422, so that the inner walls of the multiple pressure blocks 412 are fully in contact with the outer wall of the buoy.

[0051] The drive assembly 3 can drive multiple extension rods 415 on the two clamping arms 401 to move. When the multiple extension rods 415 move, they can drive two clamping plates 417 to move through the mounting plate 414, so that the two clamping plates 417 slide along the extension block 419 respectively. At this time, the third spring 430 is compressed until the clamping plates 417 are locked on the toothed plate 413. At this time, the two clamping plates 417 can be locked on the protruding teeth on both sides of the clamping block 423 respectively, thereby fixing the toothed plate 413 and preventing the support rod 404 from sliding. This allows the curvature of the multiple pressure blocks 412 in the two clamping arms 401 to be adjusted to adapt to the outer wall curvature of buoys of different sizes.

[0052] Working principle: By simultaneously activating two hydraulic cylinders 103, the two hydraulic cylinders 103 retract at the same time, and the two hinge seats 104 respectively drive the two connecting arms 107 to rotate around the axis hole of the support frame 105 through the ear plate 108.

[0053] Two connecting arms 107 drive the slide block 203 to slide synchronously in the opposite direction along the outer wall of the guide rod 206 via connecting shaft 208 and connecting block 207 respectively. When the two slide blocks 203 move, they respectively drive the limiting block 204 to slide along the inner wall of the limiting groove 205 on the limiting plate 202. At the same time, the two connecting shafts 208 can slide along the inner wall of the movable hole 109 on the connecting arm 107.

[0054] The two sliding blocks 203 move synchronously, which can drive the two clamping arms 401 to move, so that the multiple pressure blocks 412 on the inner side of the two clamping arms 401 press against the outer wall of the buoy. The multiple pressure blocks 412 drive the rotating block 411 to rotate around the rotating rod 408 as the center, and adjust the angle of the multiple pressure blocks 412 so that the pads on the inner wall of the multiple pressure blocks 412 can fully contact the outer wall of the buoy, increase the contact area and improve the friction. According to the size of the buoy, the multiple pressure blocks 412 will push the support rod 404 to slide outward along the bushing 402 a different distance. The first spring 406 on the multiple support rods 404 is compressed according to the size of the buoy. When the multiple support rods 404 slide, they will drive the slider 405 to slide along the inner wall of the guide groove 403 in the bushing 402.

[0055] Multiple support rods 404 simultaneously drive the toothed plate 413 to move. At this time, the external protrusions of the toothed plate 413 press against the second arc surface 426 on the locking block 423. The locking block 423 slides towards the side closer to the fixed seat 418, continuously adjusting the locking on the toothed plate 413. When the locking block 423 moves, it can drive the abutment rod 420 and the slide rod 424 to slide along the inner wall of the fixed seat 418, compressing the second spring 422, so that the inner walls of the multiple pressure blocks 412 are fully in contact with the outer wall of the buoy.

[0056] Two electric push rods 301 push the baffles 302 to move, so that the slide plates 303 on the two baffles 302 can slide along the inner wall of the moving groove 305 on the arc plate 304. The two baffles 302 can drive the multiple extension rods 415 on the two clamping arms 401 to move respectively.

[0057] When multiple extension rods 415 move, they can drive two clamping plates 417 to move via mounting plate 414, so that the two clamping plates 417 slide along extension block 419 respectively. At this time, the third spring 430 is compressed until the clamping plates 417 are clamped on toothed plate 413. At this time, the two clamping plates 417 can be clamped on the protruding teeth on both sides of clamping block 423 respectively, thereby fixing toothed plate 413 and preventing support rod 404 from sliding. This allows adjustment of the arc formed by multiple pressure blocks 412 in the two clamping arms 401 to adapt to the outer wall arc of buoys of different sizes.

[0058] When adjustment is needed, the electric push rod 301 drives the baffle 302 to move in the opposite direction, causing multiple clamping plates 417 to disengage from the toothed plate 413. At this time, under the elastic force of the first spring 406, multiple support rods 404 drive the toothed plate 413 to move respectively. The protruding teeth on the toothed plate 413 squeeze the clamping block 423, causing the clamping block 423 to retract inward. The multiple support rods 404 can then extend inward to the clamping arm 401, thereby allowing for readjustment according to the next buoy of a different size.
