Description
Technical field
The utility model relates to a kind of hoisting crane and moves driver's cab, roll in particular for the master of steel mill stride, in advance finishing bay mobile driver's cab and have the hoisting crane that this moves driver's cab.
Background technology
In recent years, the overweight machine of bridge-type type is when the big elevating capacity direction develops, and the span of hoisting crane is also in continuous increase.The maximum span of hoisting crane has reached 200m on the world market.Because the span of hoisting crane is big, has unobstructed sight for guaranteeing the driver, carries out hoisting operation exactly, and mobile driver's cab need be set.See that from present market mobile driver's cab mainly contains two kinds of drive forms: a kind of rigid support that is driver's cab through special use is directly connected on the trolley frame, moves with dolly through the driving of wheeling mechanism; Another kind is that driver's cab is suspended on the ad hoc mobile driver's cab track in girder below, through actuating device independently according to the orbital motion of self.
The mobile driver's cab structure that is installed on the dolly is comparatively simple, and cost is low, and being suitable for the driver must the approaching and strict operation field platform of keeping watch on load.Be particularly suitable for the long vertical workpiece of handling, and I&M work.It does not need special-purpose electric control system, and driver's operation is very convenient.But in actual use, it exists weak point, and for example: because the driver is too near from dolly, when load-engaging device was in the smallest limit position, driver's downwards angle of visibility surpassed 80 °, had limited the horizontal throw that driver's cab and load-engaging device are heard (1).(2) because driver's cab is rigidly attached on the dolly, vibration influences driver's body and mind silver carp health greatly when overweight machine operation.Certificate is to the actual measurement of a 135t/46.6m slab transfer crane of certain iron company of Canada, and the vibration acceleration force that driver's cab stands reaches 0.17N, horizontal vibration amplitude 12.7cm.Adopted pressurized air to Pneumatic spring-vibration damper afterwards, but comparatively difficulty of source of the gas is provided on hoisting crane, and expense is also high.(3) when load-engaging device hangs thing and rises near the limes superiors position, load-engaging device and hang thing and the close of driver's cab, brake suddenly like the big wheeling mechanism of hoisting crane this moment, hangs thing and very easily collide driver's cab because of swinging.The mobile driver's cab of isolated operation needs that a cover independently drives, braking and control system, and cost is high.Its advantage is can adjust driver's cab as required at any time and hang the distance between thing, when big of handling, away from hanging thing, can monitor near hanging thing in case of necessity.The running velocity of driver's cab can equal or near crab traversing speed.Hanging thing when the trolley travelling direction moves, driver's cab can guarantee that the driver has unobstructed sight in the process of operation base along with trolley travelling.
Hoisting crane as driver's cab all is installed on gate-type, the crane in bridge type, is provided with operating control in the driver's cab, the control crane job.The driver's cab of prior art generally is at the crane girder front side fixed installation bearing of walking on stage, and driver's cab is connected on the guide rail of bearing below and drives through reductor, and ladder is installed in driver's cab, is used for the driver and goes up to walking on stage.This design-calculated driver's cab makes hoisting crane whole heavy, and length of cantilever makes driver's cab fiercely rock easily at the hoisting crane glancing impact, and is unfavorable to driver physical health.
The utility model content
The purpose of the utility model provide a kind of use reliable, operate steadily, safety of operation is comfortable, installing/dismounting and hoisting crane easy to maintenance and move driver's cab.
For realizing above-mentioned purpose; The mobile driver's cab of the hoisting crane of the utility model; Comprise driver's cab body and the ladder, the platform that are used to arrive in the driver's cab, also comprise the upper and lower rail road of the cover plate up and down that is used for being located at respectively girder, last rail of square steel road is provided with adhesion wheel group, passive set of wheels and one group of horizontal wheels; Following rail of square steel road is provided with one group of horizontal wheels, and said adhesion wheel group, passive set of wheels, horizontal wheel group connect the top of driver's cab body respectively through C type framework.
Said horizontal wheels are fixedly arranged on the end frame of said C type framework.
Said horizontal wheels comprise horizontal wheel, and this horizontal wheel is installed on the end frame of C type framework through axle.
Said ladder, platform are located at the outside also rotation of said driver's cab and are risen to the height that said crane span structure girder adapts.
The hoisting crane of the utility model; Comprise crane span structure, dolly, driver's cab body and be used to arrive ladder, the platform in the driver's cab; Be respectively equipped with upper and lower rail road on the upper and lower cover plate of a girder of said crane span structure; Track centerline is corresponding to girder web line of centers; Last rail of square steel road is provided with adhesion wheel group, passive set of wheels, one group of horizontal wheels, and following rail of square steel road is provided with one group of horizontal wheels, and said adhesion wheel group, passive set of wheels and horizontal wheel group are connected the top of driver's cab body respectively through C type framework.
Said horizontal wheels are fixedly arranged on the end frame of said C type framework.
Said horizontal wheels comprise horizontal wheel, and this horizontal wheel is installed on the end frame of C type framework through axle.
Said ladder, platform are located at the outside also rotation of said driver's cab and are risen to the height that said crane span structure girder adapts.
Hoisting crane of the utility model and mobile driver's cab are welded on the upper and lower cover plate of girder through the square steel track; Track centerline is corresponding to girder web line of centers; Adjust constantly through adhesion wheel group, passive set of wheels and horizontal wheels; Guarantee driver's cab body smooth running, the driver feels that safety and comfort are reliable.Because hoisting crane moves the driver's cab device and hangs on a girder of crane bridge through square steel track extension, the driver's cab center of gravity is pressed close to the square steel track centerline, and cantilever is short, and aseismicity is good.Driver's cab, dolly have operating unit separately, and the driver can observe the lifting situation of hanging object as required in different position multi-angles.Each platform plane has abundant working space, can be through the maintenance cucurbit maintenance of factory building, and easy to maintenance, cost is low.That the utility model uses is reliable, operate steadily, safety of operation is comfortable, installing/dismounting and easy to maintenance.
Ladder, platform are arranged on said driver's cab body exterior and rotation rises to the height that described crane span structure girder adapts; Make things convenient for driver's driver's cab body of coming in and going out; And described ladder, platform and driver's cab bulk junction lump together, and can effectively control rocking of the fierce glancing impact ladder of hoisting crane.Vibrations reduce to help driver's health.
