Description
Technical field
The utility model relates to the crawler crane technical field, relates to a kind of wire rope pulley groove separation preventing device specifically.
Background technology
Present rise and fall mast or jib of construction machinery and equipment such as employing steel rope, pulley modes such as pedrail crane, truss-like continuous wall grab.Steel cord structure is by being installed on pulley yoke on the main frames such as pedrail crane, truss-like continuous wall grab, being installed on the assembly pulley on the pulley yoke and the steel rope that is installed on the assembly pulley is formed; Assembly pulley is made up of the pulley that several are installed on the sheave shaft; Sheave shaft is fixed on the pulley yoke, and steel rope is installed in the groove of each pulley outer rim.One end of steel rope is its length of stretching out by host computer control, and the other end of steel rope connects mast or jib.When transportation mast or jib, mast or jib are horizontal, and during mode of operation, mast or jib are vertical shape.Mast or jib are converted into the vertical mode of operation process from horizontal travelling position, through the host computer control rope capacity, length of steel wire rope is shortened gradually, a side of steel rope is along with the angle variation constantly takes place in the action of mast or jib in this process.
Because operating mode is abominable, often occurs steel rope disengaging pulley groove in the said process and cause danger.In order to prevent that steel rope from taking off groove, present steel cord structure improves, and L shaped backplate promptly is installed on sheave shaft, and the transverse slat of backplate is positioned at below the pulley outer rim, and the steel rope that is installed in the pulley groove can not deviate from groove.But because such construction machinery and equipment is in travelling position and mode of operation; The state of mast or jib is different; Be steel rope along with traction mast or the jib angle of rising and falling up and down constantly changes, make between steel rope and the backplate and produce interaction force, and the power of steel rope often reach tens kilograms; Backplate is easily damaged, and then the problem that makes steel rope break away from the pulley groove easily occurs again.
The utility model content
The purpose of the utility model provides a kind of wire rope pulley groove separation preventing device, and it can guarantee that under the different operating state steel rope does not break away from the pulley groove, its long service life.
In order to realize such scheme; The technical solution of the utility model is: a kind of wire rope pulley groove separation preventing device; Comprising rope processing device and two springs of being installed on the pulley yoke, said rope processing device comprises depression bar and two first otic placodes, and the upper end of two said first otic placodes is installed on the two ends of depression bar respectively; The lower end of two said first otic placodes is hinged through two second otic placodes that are provided with on bearing pin and the pulley yoke respectively; The middle and upper part of two said first otic placodes connects an end of two springs respectively, and the other end of two said springs is separately fixed on the pulley yoke, and said depression bar is against on the outer rim of each pulley of installing on the pulley yoke.
The utility model wire rope pulley groove separation preventing device, the outside face of wherein said depression bar is installed with several sleeve pipes, and each said sleeve pipe is against respectively on the outer rim of each pulley.
After adopting such scheme, the utility model wire rope pulley groove separation preventing device is installed on the pulley yoke through rope processing device and two springs, when this device busy state; Be about to mast or jib winch to vertically to the time, two springs provide enough pulling force, and the pressing plate of rope processing device is against on the outer rim of each pulley groove; Thereby make steel rope not take off groove; And when this device when mode of operation converts travelling position into, following mast or jib dropping process are as long as steel rope overcomes the elastic force of two springs and can depression bar be pushed open; And steel rope can not break away from the groove of each pulley; And this device can not be damaged yet, so this device can guarantee that under the different operating state steel rope does not break away from the pulley groove, and long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model wire rope pulley groove separation preventing device;
Fig. 2 is the embodiment scheme drawing of the utility model wire rope pulley groove separation preventing device mode of operation;
Fig. 3 is the embodiment scheme drawing of the utility model wire rope pulley groove separation preventing device travelling position.
The specific embodiment
As depicted in figs. 1 and 2, the utility model wire rope pulley groove separation preventing device comprises rope processing device 1 and two springs 2 of being installed on the pulley yoke 5.Rope processing device 1 comprises first otic placode 4 of depression bar 3 and two arcs; The upper end of two first otic placodes 4 is installed on the two ends of depression bar 3 respectively; The lower end of two first otic placodes 4 is hinged through two second otic placodes 6 of welding on bearing pin and the pulley yoke 5 respectively; The middle and upper part of two first otic placodes 4 connects an end of two springs 2 respectively, and spring 2 can adopt extension spring.The other end of two springs 2 is separately fixed on the pulley yoke 5, and the outside face of depression bar 3 is installed with four sleeve pipes 8, and four pulleys 7 are installed on the pulley yoke 5, the outer rim of respectively corresponding each pulley 7 in the position of each sleeve pipe 8.Each sleeve pipe 8 is against on the outer rim of each pulley 7.
In conjunction with shown in Figure 2; When this device busy state; Mast or jib be in vertically to, this moment, steel rope contacted with the first half of pulley groove 9, two springs 2 provide enough pulling force respectively; Pressing plate 3 is against on groove 9 outer rims of four pulleys 7, thereby makes the steel rope in the groove 9 that is installed on each pulley 7 not take off groove.
In conjunction with shown in Figure 3, when this device when mode of operation converts travelling position into, promptly descend mast or jib by vertically to the level that converts in the process of falling; Be installed on steel rope on each pulley 7 along with the action of mast or jib; To becoming gradually, angle changes steel rope by vertically, and this moment, steel rope contacted with pulley groove side semicircle; Steel rope is pushed depression bar 3 to a side through the elastic force that overcomes two springs 2, and steel rope can not break away from the groove 9 of each pulley 7.
The utility model steel rope groove separation preventing device can guarantee under the different operating state that steel rope does not break away from the groove 9 of pulley 7, and in the process of the continuous angle changing of steel rope, this device can not sustain damage, its long service life.
The above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineering staff in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
