Height adjustable docking block

Abstract

The invention discloses a height adjustable docking block. The height adjustable docking block comprises a base and a supporting seat, wherein the base comprises a base plate and a sleeve pipe; the supporting seat comprises a top plate and a lower sleeve pipe, and the lower sleeve pipe is slidably in cup joint into the sleeve pipe. The height adjustable docking block also comprises an adjusting device; the adjusting device comprises cylindrical gears rotatably connected with the outer surface of the sleeve pipe; the cylindrical gears are externally engaged with a rack; the rack is slidably connected to the outer side of the sleeve pipe; one end of the rack is articulated with a swing rod; the other end of the swing rod is articulated with a jacking block; the jacking block is supported onthe lower surface of the base plate; the outer side of the sleeve pipe is articulated with a rotating block; the swing rod passes through the rotating block to be slidably connected with the rotatingblock; a non-return mechanism is further arranged; the non-return mechanism comprises ratchets arranged on the surface of the rack; the ratchets are matched with a pawl; the pawl is articulated with the base; and the pawl is fixedly connected with a reset spring. The cylindrical gears rotate to drive a plane mechanism formed by the rack, the swing rod, the rotating block and the jacking block anddrive the supporting seat to move up and down, and a ratchet wheel is matched with the ratchets to prevent the supporting seat from falling down.

Description

technical field [0001] The invention relates to the technical field of ship tooling equipment, in particular to a height-adjustable docking pier. Background technique [0002] In the field of ship and ocean engineering construction, shipbuilding in dock is the current mainstream shipbuilding method. The hull does not fall directly on the bottom of the dock, but on rows of cement blocks with the same length, width and height. There are wooden docks between the cement blocks and the hull to adjust the level and release the water during the ship construction process. Deformation amount. [0003] With the continuous development of modern ships, all types of ships are becoming larger and larger, such as bulk carriers from 46,000DWT to 48,000DWT, then to 64,000DWT, and now 208,000DWT; container ships from thousands of TEUs to 10,000 TEUs, and now 21,000TEU; oil tanker from 114,000DWT to 158,000DWT, and then to 300,000DWT; and so on... The load capacity of the ship is getting big...

Problems solved by technology

This kind of marine height-adjustable docking pier includes a base, a support seat, and a wedge-shaped adjustment plate. The base includes a bottom plate, a guide plate, and a square tube arranged in the center of the bottom plate. The two ends are connected to the two side plates of the square tube, and the two ends of the guide plate are provided with long grooves on the corresponding two side plates, the wedge-shaped adjustment plate passes through the long groove and the lower surface is adjacent to the upper surface of the guide plate, and the support seat includes 1 top plate, 2 side plates, 1 middle plate, a middle plate is set in the middle of the bottom surface of the top plate, 2 side plates are arranged symmetrically on both sides of the middle plate, each side plate and the middle plate are connected by a pair of reinforcement plates, and the height of the middle plate is less than that of the reinforcement Plate height, the two ends of the middle plate are inserted in the two long grooves and the lower surface is adjacent to the upper surface of the wedge-shaped adjustment plate, and the two side plates are inserted in the square tube. This height adjustable The docking pier uses the principle of mechanical self-acting. The angle of the wedge-shaped adjusting plate matches the angle of the slope of the middle plate, so that when the pressure from the ship to the docking pier is transmitted to the inclined surface, the angle of force is within the self-locking angle, so that the wedge-shaped adjusting plate does not It will produce relative displacement with the middle plate under the gravity of the ship, but if the wedge-shaped adjustment plate and the plate surface of the middle plate are matched for a long time, under the pressure of gravity, the plate surface will be worn or deformed, and the wedge-shaped adjustment plate will be deformed by external force. The adjustment plate is pressed into the space between the base and the support seat, and there is also a problem of wear between the plate surface, which may cause the pressure transmitted to the plate surface to exceed the self-locking angle, posing a safety hazard
