Description

A kind of dredger wheel type trolley

Technical field

Type of the present invention relates to a kind of dredger wheel type trolley.

Background technology:

When needing short distance stepping in desilting process, existing dredger mostly adopt strut or pusher to drive hull reach, step distance step is controlled, and hull also can, because inertia can produce drift, cause desilting region incomplete in stepping process, affects dredging effect.

Summary of the invention

The object of the present invention is to provide a kind of stepping stroke to fix and adjustable dredger wheel type trolley.

Technical scheme of the present invention is:

A kind of dredger wheel type trolley, comprise guide pile, trolley track frame, trolley body, reductor, the first rope roll, the second rope roll, wire rope and pulley, guide pile is connected in trolley body, the trolley track being arranged on hull has set up upper and lower two cover slide rails, trolley body is divided into two-layer up and down, every layer is equipped with 4 wheels, be connected with the two-layer slide rail of trolley track respectively, described interconnective reductor and the second rope roll are arranged on hull, on rope roll, be wound with steel cable, steel cable is connected in trolley body by pulley, on described chassis, be provided with the first rope roll, on described the first rope roll, be wound with steel cable, one end of steel cable is connected in hull.

Further, the head of described trolley track frame and afterbody are provided with position switch.

Further again, the position of described position switch on trolley track frame is adjustable.

The present invention adopts the beneficial effect of above technical scheme to be:

Trolley body and water-bed formation are fixed, utilize reductor to connect rope roll, rope roll pulls trolley body by steel cable, relative motion between trolley body and hull, the position of trolley body is fixed on the water surface by guide pile, and the water surface is static relatively, the relative water surface of hull is subjected to displacement, realize advance and after move.On chassis, be provided with position switch, can accurately control the each mobile displacement of hull.Method of operating is simple, controls accurately.

Brief description of the drawings

Fig. 1 is embodiments of the invention figure.

In figure: trolley track frame 1, guide pile 2, trolley body 3, the first rope rolls 4, wheel 5, track 6, position switch 7, pulley 8, steel cable 9, the second rope rolls 10, reductor 11.

Specific embodiments

Specific embodiment of the invention scheme is:

As figure, a kind of dredger wheel type trolley, comprises trolley track frame 1, guide pile 2, trolley body 3, the first rope roll 4, wheel 5, track 6, position switch 7, pulley 8, steel cable 9, the second rope roll 10 and reductor 11.Described trolley track frame is fixed on the afterbody of hull, be provided with point upper and lower two cover tracks 6, the direction of track and hull parallel longitudinal, the head of guide rail 6 and afterbody are provided with two position switch 7, position switch position-adjustable in orbit, 3 points of two parts that are fixedly connected with up and down of trolley body, each part is equipped with 4 wheels 5, coordinate with upper and lower two cover guide rails respectively, the top of trolley body 3 is connected with the first rope roll, on rope roll, be wound with steel cable 9a, one end of steel cable 9a is connected on the hull of trolley body 3 cephalad direction, on described trolley body 3, be also connected with a guide pile 2, guide pile 2 can slide up and down motion on trolley body 3.The afterbody of trolley body 3 is connected with another root steel cable 9b, and the second rope roll 10, the second rope rolls 10 that steel cable 9b is connected on trolley track frame 1 side hull by pulley 8 are connected with reductor 11.

Its operating principle is: trolley body 3 is positioned at the original position of the head of trolley body rail bracket 1, under free state, put down guide pile 2 make its by self gravitation in hydrolocation, starting reductor 11 drives rope roll 10 to rotate, steel cable 9 is led and is pulled back trolley body 3 and move to hull afterbody through pulley 8, because trolley body 3 is fixed through guide pile, the track 6 of trolley track frame 1 occurs to the displacement of hull cephalad direction with the wheel 5 of trolley body 3, trolley track frame 1 with hull for being fixedly connected with, drive hull moves forward, in the time that the position switch 7 of the afterbody on trolley track frame 1 touches trolley body 3, reductor stops operating, hull completes reach.

Now, trolley body 3 is positioned at the afterbody of trolley track frame 1, and guide pile 2 is sling from water, removes location.Start the first rope roll 4 and pull steel cable 9a, steel cable 9a one end is connected in hull, in the first rope roll 4 rotation processes, steel cable 9a pulls the trolley body 3 being fixedly connected with the first rope roll along track 7 to hull head movement, until touch the position switch 7 of trolley track frame head, the first rope roll 4 stops operating, and trolley body 3 is got back to original position.And so forth, hull is interrupted forward movement with fixed journey system.

While moving after hull needs, trolley body 3 is pushed to the afterbody of trolley track frame 1, put down guide pile 2, be fixed in water, by pulley 8, the steel cable 9b on the second rope roll is connected to the head of trolley body 3, start reductor 11, the second rope roll 10 pulls steel cable 9b to drive trolley body to move to hull cephalad direction, because trolley body 3 is fixed through guide pile, there is the displacement of stern direction in the track 6 of trolley track frame 1 and the wheel 5 of trolley body 3, trolley track frame 1 with hull for being fixedly connected with, drive hull to move backward, in the time that the position switch 7 of the head on trolley track frame 1 touches trolley body 3, reductor stops operating, hull moves after completing.
