Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments. The following examples are carried out on the premise of the technical scheme of the invention, and detailed embodiments and specific operation processes are given, but the scope of the invention is not limited to the following examples.
Example 1
A ship lock floating type mooring post tripping device comprises a mooring post sleeve rocker pulley assembly 1, a pressure plate spring energy storage assembly 2, a tripping locking assembly 3 and a buoy support 4. The mooring column sleeve rocker pulley assembly 1 comprises a mooring column sleeve 11, a mooring column rocker 12, a pulley 13 and a torsion spring 15. The mooring post sleeve 11 is provided with a sliding groove 111, and the upper part of the mooring post sleeve is used for mooring a ship in a lock chamber. The pressing plate spring energy storage assembly 2 comprises a pressing plate 21 contacted with the pulley 13 and a compression spring 22 arranged at the rear end, wherein a triangular block (gradient guide rail 23) with a certain gradient is arranged at the upper part of the front end of the pressing plate 21, and a locking buckle 31 is arranged at the lower part of the pressing plate 21. The trip locking assembly 3, as shown in fig. 4, includes a locking lever 32 contacting a lower portion of the pressure plate 21, a reset rocker 33 contacting the pulley 13, and a transmission link 34. The buoy bracket 4 is a truss structure erected on the buoy, rollers are installed on two sides of the buoy bracket, and the main function is to support a mooring post and a tripping device. The individual components are mounted on the pontoon mount 4 by means of shaft pins.
When the mooring rope of the ship is hung on the upper part of the mooring pillar sleeve 11, the mooring rope force applied to the whole device can be decomposed into a horizontal component and a vertical component. Wherein the horizontal component force is pressed to contact and sleeve the inner bollard rocker 12 through the bollard sleeve 11, so that the whole bollard sleeve rocker pulley assembly 1 bears a rotation moment, and the assembly has a rotation trend. The bollard sleeve rocker pulley assembly 1 rotates to drive the bottom pulley 13 to roll on the slope guide rail 23. The rolling of the pulleys 13 on the sloped rails 23 causes the platen 21 to have a tendency to rotate downward. As long as the slope track of the triangular block is satisfied to cover the rotation track of the pulley endpoint of the mooring bollard sleeve rocker pulley assembly 1, the end part of the pressing plate 21 moves downwards, and meanwhile, the compression spring 22 at the end part of the pressing plate 21 stores energy.
The vertical component of mooring force along the mooring column causes the mooring column sleeve 11 to have an axial tendency to move on the mooring column rocker 12. Because the bollard sleeve 11 is provided with the sliding groove 111, the rocker fixing shaft pin 14 for fixing the rocker passes through the sliding groove 111, so that the bollard sleeve 11 can move axially on the bollard rocker 12, and therefore, the vertical component force at the upper end of the bollard can be transmitted to the triangular block through the contact of the pulley 13 at the bottom, and the pressing plate 21 also has the tendency of rotating downwards. The end of the pressure plate 21 moves downward while the end of the pressure plate 21 compresses the spring 22 to store energy.
The stiffness of the compression spring 22 and the apex of the triangle block slope are designed, and the mooring bollard has a conventional mooring function by ship as long as the pulley 13 at the end of the mooring bollard rocker 12 is within the triangle block slope. When the lock chamber is used for filling and draining water, the floating mooring post is blocked in the guide groove, the height difference between the ship and the mooring post is gradually increased, the mooring force is increased, and the included angle between the mooring rope and the plane of the mooring rope is increased. When the mooring force, including the horizontal component and the vertical component, reaches a set threshold, i.e., the compression amount of the spring by the pressing plate 21 reaches the set threshold, the pulley 13 is disengaged from the apex of the triangular slope. The mooring bollard sleeve rocker pulley assembly 1 loses the bottom constraint and rotates towards the lock chamber under the action of the mooring rope force, and the mooring rope is separated along with the rotation of the lock chamber, as shown in fig. 5.
When the pressing plate 21 rotates the compression spring 22 downwards to reach the threshold point, the locking catch 31 at the bottom of the pressing plate 21 interacts with the locking lever 32, and the catch is engaged to lock the rotating position of the pressing plate 21. After bollard sleeve pulley 13 is clear of the point of slope, hold down plate 21 remains locked as shown in fig. 5. When the mooring rope is separated from the mooring bollard, the mooring bollard rocker 12 returns to move under the action of the torsion spring 15 and smoothly passes through the highest point of the triangular block in the locking state. The bollard is reset to the vertical position, the pulley 13 touches the upper part of the reset rocker 33 under the action of inertia, the reset rocker 33 enables the locking rod 32 to swing through the transmission connecting rod 34, the occluded buckle is separated, the release pressure plate 21 is restored to the original position, and the whole device is restored to the initial state.

The structure of the mooring post sleeve rocker pulley assembly 1 is shown in fig. 3 and comprises a mooring post sleeve 11, a mooring post rocker 12, a pulley 13, a rocker fixing shaft pin 14 and a torsion spring 15, wherein the mooring post rocker 12 is fixed on the buoy support 4 through the rocker fixing shaft pin 14 and the torsion spring 15, the mooring post sleeve 11 is sleeved on the outer side of the mooring post rocker 12, a mooring cap is arranged at the top, a cable limiting block is arranged at the middle upper part, the pulley 13 is arranged at the bottom of the mooring post sleeve 11, a sliding groove 111 is vertically arranged on the side wall, and the fixing shaft pin 14 penetrates through the sliding groove 111.
The structure of the pressure plate spring energy storage assembly 2 is shown in fig. 2, and comprises a pressure plate 21, a compression spring 22 and a slope guide rail 23, wherein the slope guide rail 23 is a triangular block with a certain slope, is arranged on the upper portion of the front end of the pressure plate 21 and is in contact with the pulley 13, and the compression spring 22 is arranged on the lower portion of the rear end of the pressure plate 21. The trip locking assembly 3 is arranged on the pressure plate spring energy storage assembly 2, and the structure of the trip locking assembly 3 is shown in fig. 4 and comprises a locking buckle 31, a locking rod 32, a reset rocker 33 and a transmission connecting rod 34, wherein the locking buckle 31 is arranged at the bottom of the pressure plate 21, the reset rocker 33 is rotatably arranged at the front end of the pressure plate 21 and is in contact with the pulley 13, the reset rocker 33 is connected with the locking rod 32 through the transmission connecting rod 34, and the locking rod 32 and the end part of the locking buckle 31 are both provided with buckle structures which can be matched with each other to lock the pressure rod 21.

The tendency of rotation and axial movement of bollard sleeve 11 is transmitted through the contact of bottom pulley 13 with ramp rail 23, causing pressure plate 21 to have a tendency to rotate downward. As long as the slope track of the slope guide rail 23 covers the rotation track of the pulley endpoint of the mooring pillar sleeve rocker pulley assembly 1, the end part of the pressure plate 21 moves downwards, and meanwhile, the compression spring 22 at the end part of the pressure plate 21 stores energy. When the rocker end pulley 13 is in the grade guide rail 23, the mooring columns have a conventional mooring function by ship. When the mooring force, including the horizontal component and the vertical component, reaches a set threshold, i.e., the compression of the spring by the pressure plate 21 reaches a set threshold, the pulley 13 disengages from the apex of the slope of the sloped rail 23. The mooring post sleeve rocker pulley component 1 loses the constraint of the bottom, rotates towards the lock chamber under the action of a mooring rope force, and the mooring rope is separated, so that the automatic threshold tripping function is realized.
When the pressure plate of the tripping locking assembly rotates downwards and the compression spring reaches the threshold point, the locking buckle at the bottom of the pressure plate interacts with the locking rod of the tripping locking assembly, the buckle is occluded, and the rotating position of the pressure plate is locked. After the boat mooring column sleeve pulley is separated from the gradient point, the pressing plate keeps a locking state. When the mooring rope is separated from the mooring post, the mooring post rocker returns to move under the action of the torsion spring and smoothly passes through the highest point of the pressing plate triangular slope in a locking state. The mooring post is reset to a vertical position, the pulley touches the upper part of the reset rocker under the action of inertia, the reset rocker enables the locking rod to swing through the transmission connecting rod, the occluded buckle is separated, the release pressing plate is restored to the original position, the whole device is restored to the initial state, and the automatic reset function is realized.
