Detailed Description

The invention is elucidated below with reference to the accompanying drawing.

The invention is composed of a track 10, a ship bed-jig 1, a caster, a spiral support 2, a three-core pulley, a steel rope 16 and a winch 11, wherein: spiral brace 2 is installed in the bed-jig 1, and fixed pulley 3 is installed in bed-jig both sides, and three-core pulley is connected after steel cable 16 penetrates fixed pulley 3 of bed-jig 1 both sides, leads to hoist engine 11 through the rim plate of three-core pulley, and the truckle is installed in bed-jig 1 bottom, and whole bed-jig 1 is on through truckle embedding track 10.

Its spiral props 2 main driving force and is the spiral section of thick bamboo, and the design of spiral section of thick bamboo shape is the cylinder, and the reason is that the cylinder appearance can spiral lift, plays the transmission moment effect, and other shapes can not rotate, and length is the same because the spiral section of thick bamboo can overlap into the length of one section of thick bamboo after descending, and big back is a section of thick bamboo and overlaps necessary condition before, gives consideration to whole flexible process stability simultaneously.

The internal and external screw threads of the spiral cylinder are fully distributed on the whole cylinder, a small part of the back edge of the inner diameter has no screw thread, the diameter of the screw thread of the small part of the front edge of the inner diameter is smaller than that of the rest part, and the diameter of the screw thread of the small part of the back edge of the outer diameter is larger than that of the rest part, so that the purposes are as follows: after each spiral lifting cylinder rotates forwards, the cylindrical threads can rotate continuously to generate the disconnection between the cylinder and the cylinder, the diameter of the threads at a small part of the front edge of the inner diameter is smaller than that of the rest part, the diameter of the threads at a small part of the length of the outer diameter is larger than that of the rest part, the external thread of the rear spiral lifting cylinder with most length can be matched with the thread of the front part of the internal diameter of the front spiral lifting cylinder with a small part, the thread of the rear part of the external diameter of the rear spiral lifting cylinder with a small part is matched with the thread of the front spiral lifting cylinder with most length, the structure can ensure that the spiral lifting cylinder moves forwards and backwards smoothly and brake is added to the spiral lifting cylinder, when the spiral lifting cylinders are completely forward and backward, a small part of the screw thread with a larger diameter of the latter spiral lifting cylinder props against a small part of the screw thread with a smaller inner diameter of the former spiral lifting cylinder, so that the overlapping between the cylinders is formed; a small part of the back edge of the inner diameter has no screw thread, so that the brake is added when the spiral lifting cylinder moves forwards and backwards, and the back part of the back edge of the back spiral lifting cylinder is prevented from passing through the bottom edge of the front spiral lifting cylinder and moving forwards.

Its end section of thick bamboo 5 only has the internal thread, does not have the external screw thread, and top section of thick bamboo 6 only has the external screw thread, does not have the internal thread because the internal thread is with transmitting power to other section of thick bamboos between a section of thick bamboo and a section of thick bamboo, and the external screw thread is accepted other section of thick bamboo and transmits the power of coming. After the bottom barrel 5 receives the torque transmitted by the motor, the force of other barrels does not need to be received, so that external threads do not exist, and the top barrel 6 does not need to transmit the force to other barrels, so that internal threads do not exist.

The two ends of a supporting rod 7 of the device are processed into petal shapes and are mainly used for connection between the supporting rods, one supporting rod is sleeved with one rod, and the thickness of the end heads at the two sides is required to be larger than the thickness of the cylinder wall.

Its caster wheel point of force is at wheel 13, and rotating flap 14 acts to secure track 10. Because dam-passing track 10 designs for three, the quantity of truckle can not share weight, and too much easy card wheel causes the truckle card to die, adopts rotatory separation blade 14 can prevent that the truckle card from dying, and rotatory separation blade 14 plays the effect of cover the truckle on track 10.

The design of the track 10 is one more than that of a common track, and the track is used for sharing the weight of a large-scale load-carrying ship when going ashore and averagely sharing the weight by using the multiple tracks.

The track 10 is designed into an arc shape because the dam and the dam bottom are two planes, the plane on the dam is a water surface, the height of the track when a ship passes the dam must be larger than the horizontal plane, namely when one plane rises to the other plane, the angle cannot be a right angle, and a radian is needed.

The invention finishes two steps when the dynamic analysis of the dam-crossing frame rail is implemented, firstly, the caster under the ship jig frame 1 needs to be corrected on the track 10, the rotary blocking piece 14 on the caster is put down, the rotary blocking piece is rotated to the side of the wheel 13, and the bolt of the rotary blocking piece is screwed so that the caster is fixed on the track 10; then four steel ropes 16 are led into double pulleys of the three-core pulleys at the head end and the tail end of the ship jig 1 from a winch 11 on the dam, and the steel ropes of the fixed pulleys 3 on the two sides of the ship jig penetrate into single pulleys of the three-core pulleys; these mounting fixtures are disposable and need not be repeated thereafter, regardless of the position to which the boatlift rack 1 is moved. The second step is to drive the ship that needs to pass through the dam 9 to the ship bed-jig, put through spiral brace motor 8 power, motor 8 forward rotation impels the tire that the spiral props the top to prop up the hull both sides, fixed hull, then connect four hoist engine 11 power about the dam, the umbilical disc of two hoist engines on the dam is clockwise turning, drag the ship to move to the dam 9, the hoist engine is reverse to move under the dam, release the steel cable in the umbilical disc, avoid producing reverse strength, after the ship moves to the surface of water on the dam, spiral brace motor 8 reverse rotation, release the fixed to the hull, the ship breaks away from bed-jig 1 because of buoyancy, free run.

When the ship moves downwards from the dam, the principle is the same, but when the ship passes through the dam, two winches under the dam need to be started to be pulled, and in other time, the two winches under the dam are always in an unstressed state, steel ropes of the winches are in a relaxed state, and when the ship is in a track descending state, the steel ropes are still tensioned by the winches on the dam.
