Description

The working principles of the above two equipments are the same. After the pipe piles are moved to the tooling bearing beam and padded, the bearing beam and the pipe piles are pushed to the required height by the jacking oil at both ends of the bearing beam, the hydraulic system maintains pressure, and then the winch is started to reel in the wire rope, and the traction equipment slides forward along the slide seat together with the pipe piles to drop into the barge; the above equipment has some design defects:

[0003] 1) Because the system operation is not designed for centralized control, the jacking points of the piles and the sliding on both sides cannot be synchronized. The tooling is prone to unbalanced loads and sliding deviations, and can only be adjusted manually, which has low efficiency and poor precision, and also affects the life of the tooling.

[0004] 2) The sliding of the tooling is pulled by two winches with poor synchronization. Impact force will be generated when starting.

[0055] Working process:

[0056] First, install the ship's top-pushing slideway on the transport ship, and then hoist the sliding bracket A and sliding bracket B into the slideway of the ship's top-pushing slideway in the order of front and back, and sail to the front edge of the wharf where the shore top-pushing slideway has been installed. After the ship's and shore's slideways are aligned, tie the mooring pile rope; after the transport vehicle transports the pipe pile over the top of the sliding bracket B to the sliding bracket A, the steel strand lifting device of the sliding bracket A lifts the pipe pile to a certain height, and the sliding bracket A's pushing device pushes the pipe pile forward together with the transport vehicle at the same time, and the transport vehicle stops about 3m away from the front edge of the wharf; move the sliding bracket C horizontally to the tail end of the pipe pile, and the sliding brackets A and B are moved forward. The steel strand lifting device of sliding bracket C lifts the pipe piles at the same time, and the transport vehicle moves out of the slideway area; the pushing devices of sliding bracket A and sliding bracket C push the pipe piles forward at the same time, and when sliding bracket C approaches the front edge of the wharf, the pushing stops; the steel strand lifting devices of sliding bracket A and sliding bracket C lower the pipe piles at the same time, and the pipe piles fall onto the adjusting seat device of sliding bracket B, the steel strand lifting device of sliding bracket A stops lowering, and the steel strand lifting device of sliding bracket C continues to lower, and after its adjusting seat device is separated from the pipe pile for a certain distance, it pushes and moves horizontally to its original position; the transport ship sets sail, and the sliding and landing of the pipe piles is completed.

[0057] Sliding bracket

[0058] Each set of sliding support consists of two sets of steel strand lifting devices, four sets of jacking devices, four sets of safety brake devices, two sets of adjustment seat devices, one set of transverse movement device (only equipped with sliding support C), two base beams, four columns, one bearing beam, two upper beams, two main pump stations, etc.

[0059] The base beam, column and upper cross beam are connected with bolts to form left and right frames. The center distance between the left and right frames is 11m. The load-bearing beam is installed on the inner side of the column of the two frames before the upper cross beam is installed; the two sets of adjustment seat devices and the bases at both ends of the load-bearing beam are connected with pins; the main oil top of the steel strand lifting device is bolted to the top cross beam of the two frames, and the anchor seat is fixed in the cavity at both ends of the load-bearing beam. One end of the whole bundle of steel strands is inserted into the anchor seat, and the other end is inserted into the upper and lower anchors of the main oil top, and the two ends are anchored and clamped; the two main pump stations are fixed at the same end of the two base beams respectively; when lifting pipe piles, start the two main pump stations, and the two main oil tops work to repeatedly retract the steel strands upward, thereby driving the load-bearing beam carrying the pipe piles to be lifted upward to the required height along the slide plate inside the column. The same applies when the pipe piles need to be lowered.

[0060] The jacking device is installed on both sides of each base beam, with a total of four sets. One end of the jacking oil cylinder is connected to the base welded on the side of the base beam with a pin shaft, and the other end is connected to the slide seat with a guide slide rod on the jacking slideway with a pin shaft; each set of jacking device is equipped with a jacking limit device, which is welded on the side of the base beam and above the jacking device; when the jacking pile slides, the two main pump stations are started, and the four jacking oil cylinders work at the same time to push the slide seat with the guide slide rod to move forward along the slideway for a fixed stroke. When not jacking, the guide slide rod is inserted into the slideway through the guide hole of the slide seat. When the jack is in the forward position, the guide slide bar moves forward and the jack is moved back to the stop groove, and the guide slide bar moves forward and the jack is moved back to the stop groove, and the limit switches at one end of each jack are triggered at the same time. The jack cylinders work in the reverse direction, and after the bracket is pulled forward for a fixed stroke, the limit switches at the other end of each jack are triggered at the same time. The jack cylinders resume forward work, and a working cycle of jacking and sliding is completed. The above operation can be repeated to realize the sliding and dropping of the pipe pile.

[0061] A total of four sets of safety braking devices are installed on the inner sides of both ends of the two base beams, and are equipped with a speed control device. The safety braking device is composed of a windproof iron wedge and a brake wheel group. The mounting plate of the windproof iron wedge is bolted to the connecting plate at the end of the base beam, and the brake wheel group is bolted to the lateral base of the base beam; the speed control device is mainly used to detect the sliding speed of the bracket. When the sliding speed exceeds the pushing speed of the pushing cylinder by about 20%, the windproof iron wedge is immediately powered off, and the thruster push rod is placed on the slideway under the action of the spring force and through the lever. The brake wheel is wedged after the iron wedge rolls a short distance, and the bracket is self-locked and cannot slide; after the windproof iron wedge is powered on, the thruster push rod rises rapidly, and lifts the iron wedge through the lever and transmission mechanism, and the bracket can start to slide normally.

[0062] The adjusting seat device is composed of a 10m hinge seat, an 8m adjusting seat and a 6m adjusting seat; the 10m hinge seat and the bearing beam base are connected with a pin, and bolts are used to connect the adjusting seats or the hinge seats; by combining the three seats in different ways and inserting adjustment gaskets, it can be used for the bearing and movement of pipe piles with a diameter ranging from 6m to 10m.

[0063] The transverse movement device is composed of eight active bicycles with oil jacks, pump stations, electrical systems, etc.; the cantilever beams of the active bicycles are connected to the bases on both sides of the base beam by bolts, and the pump station and electrical system are fixed on the connecting frame between the two vehicles; before transverse movement, the hooks on both sides of the base beam of the sliding bracket are hooked to the shore push slideway, the two pump stations are started, and the oil jacks are lifted at the same time. When the lower plane of the shore push slideway is about 50cm away from the ground, it starts to move horizontally to the designated position, and the oil jacks are continuously retracted to align the shore push slideway. After completion, the oil jacks are continued to be retracted. When the wheels are about 50cm away from the ground, the bracket is pushed to the tail end of the pile for the next step.

[0064] Push slide on board

[0065] The ship's push slides are arranged longitudinally in two rows on the transport ship with a center distance of 11m. The two rows have the same structure; each row is 90m long and is composed of 10 sections of standard slides connected by pins. The slide groove designed on the inner side of the slide is used as a slide for the push sliding of the sliding bracket, and the two outer sides are designed with tracks for the movement of the slide seat and stop grooves for the guide slide rod.

[0066] Shore push slide

[0067] The onshore pushing slideway is composed of the onshore pushing slideway A and the onshore pushing slideway B. The onshore pushing slideways A and B are respectively arranged longitudinally in two rows on the shore with a center distance of 11m. The two rows have the same structure. Each row is 36m long and is composed of 6 sections of standard slideways connected by pins. The slideway groove designed on the inner side of the slideway is used as a slideway for the pushing and sliding of the sliding bracket. The two outer sides are designed with tracks for the movement of the slide seat and stop grooves for the guide slide rod. The onshore pushing slideway B has two sections, each 8m long, and has the same structure as the onshore pushing slideway A. It is later fixed with the sliding bracket C and moved horizontally into place, and then pinned to the onshore pushing slideway A.

[0068] Electrical System

[0069] It consists of an electrical room, a main power distribution cabinet, a main control console, control cabinets beside each support machine, and a control cabinet for the transverse device, etc. It can remotely realize the lifting, longitudinal movement, transverse movement, linkage, interlocking, and protection of the sliding support.

[0070] The operation of the system of the present invention is designed to be remotely controlled. The lifting, longitudinal movement, lateral movement and other actions of the sliding bracket can be synchronized. The bracket is subjected to force without unbalanced load and deflection, with high work efficiency and accurate precision. The sliding of the tooling adopts the synchronous pushing of the oil cylinder, without impact force and deflection. The lifting of the pipe pile applies the principle of the continuous acting hydraulic jack. When the pipe pile is lifted, the steel strand is always bearing the load. Even if the oil circuit fails, there will be no safety problem, thus preventing the occurrence of safety accidents. It has a lateral movement function, high work efficiency and no safety risk. It is equipped with a safety brake device, which can self-lock and stop immediately regardless of normal shutdown or emergency situation. Especially under conditions with a large slope, the car will not slip, thus preventing the occurrence of safety accidents involving people or property.
