Description
Technical field
The present invention relates to hoisting crane, be meant a kind of flexible bend running technology for electric single-beam crane especially.
Background technology
The sluice maintenance of existing river, every sluice need dispose bulkhead gate and hoisting device.Both make two rivers be in adjacent two the very near sluice of " fourth " font intersection, generally also needed respectively to dispose a cover bulkhead gate and a hoisting device.This maintenance configuration state, not only apparatus installation work amount big, to the troublesome maintenance of repair apparatus, and caused the waste of funds, manpower.
Summary of the invention
Technical matters to be solved by this invention just be to overcome the river be in adjacent two the very near sluice of " fourth " font intersection at present must the configuration two cover apparatus installation work amounts that bulkhead gate and hoisting device caused big, the troublesome maintenance and the funds of repair apparatus are wasted big defective with manpower, an a kind of shared cover bulkhead gate and hoisting device of two sluice that make are provided, the operation of hoisting device mono beam overhead crane by change into along the rectilinear orbit operation not only can along linear running, but also can be along the flexible bend running technology of arc-operation.Flexible bend running technology for electric single-beam crane method of the present invention, device comprises that the river is in adjacent two the very near sluice of " fourth " font intersection, configuration one cover shared bulkhead gate and mono beam overhead crane, mono beam overhead crane not only can along linear running, but also can be along arc-operation; (1) two lock line of centers angle of cut is 90 °, lock top headstock gear and also becomes 90 ° of angles of cut to arrange, the mono beam overhead crane orbit between two locks is an arc section at 90 ° of angle of cut positions; (2) mono beam overhead crane mechanism is made up of girder, end carriage and steered wheel, single speed drive motor, double speed drive motor, sensing contact signal controller, the two ends of girder are respectively end carriage, be respectively steered wheel before and after the bottom of end carriage, two ends end carriage steered wheel is that bilateral drives, wherein the outer side track steered wheel is driven by the single speed drive motor, and the inner track steered wheel is driven by the double speed drive motor; The sensing contact signal controller is made of contact and wiping sheet, and inboard end carriage outer lower end is installed contact, with the contact contact site wiping sheet is installed on the longitudinal bearer of inner arc track.Two groups of steered wheels before and after being provided with below each end carriage of mono beam overhead crane, steered wheel connects and can turn to flexibly by vertical bearing with end carriage, and steered wheel has run on the rail that closes on the interior cement upright column bracket of machine room.Every group of steered wheel both sides of end carriage are provided with a side direction horizontal guide sheave, directly with rail side to contacting.Track is more than 5000 millimeters at the inner arc radius of 90 ° of angle of cut position arc sections between two locks, and outer arc radius adds institute's use mono beam overhead crane span size for the inner arc radius size; External arc and interior circular arc concentric.The mono beam overhead crane span is 8.5 meters, can also determine according to the actual conditions and the different shaping size of manufacturer's hoisting crane of headstock gear.Mono beam overhead crane operating unit outer side track steered wheel single speed drive motor rotating speed is 1330 rev/mins, and inner track steered wheel double speed drive motor rotating speed is 1330/520 rev/min.The contact of sensing contact signal controller contacts with the wiping sheet or when breaking away from, transducing signal directly reaches control box by the sensing contact signal controller, carries out speed by control box control double speed drive motor and switches.Mono beam overhead crane moves with constant angular velocity at 90 ° of angle of cut position arc orbits, and wherein the outer arc linear velocity is 20.0 meters/minute, and the inner arc linear velocity is 8.07 meters/minute.Compare with existing hoisting device mono beam overhead crane, the main improvement content of mono beam overhead crane of the present invention comprises: (1) former mono beam overhead crane operates to one-sided driving and changes the bilateral driving into, is suitable for the operation of arc section track; (2) two groups of fixing vehicle wheels that are provided with before and after below each end carriage of former mono beam overhead crane change steerable vehicle wheels into, and the wheel box connects and can turn to flexibly by vertical bearing with end carriage, and it is driven wheel that one group of front and back steered wheel is set to adhesion wheel, one group; (3) every group of steered wheel both sides leading edge of end carriage set up a side direction horizontal guide sheave, directly play the guiding role to contacting with rail side, and avoids wheel to produce derailing when arc section moves and gnaw the rail phenomenon; (4) the inner track steered wheel adopts double speed drive motor control wheel running velocity, adapts to and moves with constant angular velocity at the arc section track.When needs overhaul gate, mono beam overhead crane is moved to the bulkhead gate storeroom, can be with the bulkhead gate handling to the lock hole that needs maintenance, external side end beam steered wheel maintenance speed operation together in rectilinear orbit section mono beam overhead crane in the operational process; When entering 90 ° of angle of cut position arc orbit sections, the driving line speed of steered wheel still remains unchanged with linear portion on the outer arc track, the sensing contact signal controller contact at inboard end carriage position contacts with the wiping sheet, send variable rate signal, make the double speed drive motor of inner track steered wheel carry out the moment switching of speed change by variable speed control mechanism, on the inner arc track driving line speed of steered wheel slow down with the outer arc track on steered wheel keep the constant angular velocity operation with respect to the circular arc center of circle, mono beam overhead crane can smooth-goingly be turned at the arc section track moves ahead; When entering another rectilinear orbit section, the driving line speed of steered wheel still remains unchanged on the outer arc track, sensing contact signal controller contact and wiping sheet on the inboard end carriage are thrown off, variable speed control mechanism switched the moment that the double speed drive motor carries out speed change more simultaneously, the inner track wheel recovers former wire speed again, keeps with the speed arrival assigned address that advances with the outer arc rail wheel.
Advantage of the present invention just is to provide a kind of adjacent very near shared cover bulkhead gate of two sluice of " fourth " font intersection and flexible bend running technology for electric single-beam crane of hoisting device of being in the river, avoided the big difficulty of weight-lifting equipment device installation work amount, reduced the trouble that repair apparatus is safeguarded, and stopped waste, saved funds and manpower.Mono beam overhead crane mechanism two ends end carriage steered wheel adopts bilateral to drive, carry out moment 90 ° of arc orbit sections by the sensing contact signal controller and switch and to have guaranteed that interior outer arc track steered wheel keeps the constant angular velocity operation with respect to the circular arc center of circle, in can effectively preventing constant derailing that causes of outer arc track steered wheel running velocity or outer arc track steered wheel keep running velocity and the stall of inner arc track steered wheel driven slide cause gnaw the rail phenomenon; And lead at the steered wheel wheel rim by the side direction horizontal guide sheave during mono beam overhead crane operation, two groups of steered wheels in front and back that each end carriage is provided with below can freely turn at the camber line orbital segment and move ahead, the side direction horizontal guide sheave that every group of steered wheel both sides are provided with plays directional tagging by itself and track contact both sides and has avoided wheel to occur derailing, blocking the rail phenomenon during moving ahead, thereby has guaranteed safe in operation.Therefore the present invention has the vast market promotion prospect.
