Abstract
The invention discloses a trailing type cab connecting device used for a crane, which comprises an upper link span, a lower link span, a vertical spacing beam, a horizontal spacing beam, a top vibration isolator group and an under-part vibration isolator group; wherein the upper end of the top vibration isolator group is arranged on the upper link span by a bolt and a flange and the lower end is connected with the top of the crane by a bolted connection type; the lower end of the under-part vibration isolator group is arranged on the lower link span by the bolt and the flange and the lower end is connected with the bottom of the crane by the bolted connection type. The isolator groups comprise laminated rubber, an upper flange and a lower flange; an armor plate is embedded between the laminated rubbers; the upper flange and the lower flange are both provided with screw holes. As the vibration isolators are arranged between the steel structure of the crane and the crab, the vibration isolators have the function of vibration isolation, thus solving the excess vibration of the crab caused by the traditional connecting device, strengthening the comfort level of drivers and increasing the working efficiency of the crane.

Fast development along with international trade, shore container crane unloads shipment machinery constantly towards maximization, high efficiency development as main, the running velocity of dolly improves constantly, the fastest 340m/min that reaches, and hoisting crane is connected on the dolly by a steelframe usually at an upper portion thereof with trailing type cab.Owing to be subjected to the influence of wind effect etc. when the frequent acceleration of dolly, deceleration and lifting cargo, the driver's cab vibration obviously, and because the bank bridge is in wharf apron work, its wind area is big, sail-center height, center of gravity height, cause that very easily wind shakes, operating personal in the driver's cab is exerted an influence, cause the driver short time to enter fatigue state, reduce work efficiency, not only waste human cost, also reduced the work efficiency of hoisting crane.The common practice of head it off is to improve the integral rigidity of connecting device structure in the engineering at present, quickens the vibration damping of driver's cab, has caused the increase of connecting device structural weight, cost to increase though can alleviate the vibration of driver's cab like this.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the objective of the invention is to design a kind of vibration that can significantly reduce driver's cab, strengthen driver personnel comfort level, improve hoisting crane work efficient, alleviate structural weight, reduce the hoisting crane trailing type cab connecting device of manufacturing cost.
To achieve these goals, technical scheme of the present invention is as follows: a kind of hoisting crane comprises link span with trailing type cab connecting device, following link span, the vertical spacing beam, the cross spacing beam, top vibration isolating pad group and bottom vibration isolating pad group, the described link span of going up is installed on the dolly of hoisting crane respectively with following link span by welding manner, the upper surface of the lower surface of link span and following link span is welded with flange respectively on described, described vertical spacing beam is installed in respectively between link span and the following link span by welding manner, described cross spacing beam is welded on respectively on link span and the following link span, bolt is passed through in vibration isolating pad group upper end, described top, flange is installed on the link span, the lower end is connected with the driver's cab top by bolt connecting mode, bolt is passed through in vibration isolating pad group lower end, described bottom, flange is installed in down on the link span, and the upper end is connected with the driver's cab bottom by bolt connecting mode.
Top of the present invention vibration isolating pad group is made up of 8 vibration isolating pads.
The vibration isolating pad quantity of bottom of the present invention vibration isolating pad group is identical with the vibration isolating pad quantity of top vibration isolating pad group.
Vertical spacing beam of the present invention is 6, and the front and back symmetry is installed, and the cross spacing beam is 4, and symmetry is installed up and down.
Vibration isolating pad of the present invention comprises laminated rubber, upper flange plate and lower flange, is embedded with steel plate between the described laminated rubber, on upper flange plate and the lower flange screw is arranged.
A kind of hoisting crane is determined as follows with the choosing method of the vibration isolating pad rigidity of trailing type cab connecting device:
Wherein: ω---excitation frequency;
κ---vibration isolating pad horizontal rigidity;
M---vibration isolating pad quality.
Compared with prior art, the present invention has following beneficial effect:
1,, thereby solved the excessive problem of the driver's cab that traditional connecting device caused vibration because the present invention has installed vibration isolating pad between the steel structure of hoisting crane and driver's cab, this vibration isolating pad has the vibration isolation effect.
2, because the present invention has reduced the vibration of driver's cab, thereby strengthen driver's comfort level and improved its work efficiency, saved human cost, improved the work efficiency of hoisting crane.
3, the present invention is simple in structure, is convenient to safeguard.
