Description

A kind of material descending lifeline
Technical field
The utility model relates to a kind of material descending lifeline, belongs to material unloading equipment or device technique field.
Background technology
Along with the expansion gradually of plant capacity, the expansion day by day of Logistics Market, the total amount of turnover goods is also increasing, unloaded of cargo number of times is more frequent, when unloaded of cargo, due to the deficiency of staff, some carman directly throws away ground by goods, quality to goods causes adverse influence, causes sometimes serious adverse consequences.
Summary of the invention
For the deficiencies in the prior art part, the utility model proposes a kind of material descending lifeline, the utility model is rational in infrastructure, and friction coefficient is little, and reliability is high, high safety, and unloaded of cargo that can be fast and safely guarantees that cargo security arrives ground.
The utility model is mainly by the following technical solutions: a kind of material descending lifeline, and this descending lifeline comprises load carrier, load carrier is provided with transmission device and buffer gear;
Described load carrier comprises symmetrically arranged crossbeam, bracing frame, overhead gage and lower baffle plate; The bracing frame being arranged symmetrically with is installed on one end of crossbeam, and crossbeam low side is connected with overhead gage, is high-endly connected with lower baffle plate;
Described transmission device comprises major axis I, major axis II, chain, chain crawler belt, sprocket wheel I and sprocket wheel II; Major axis I is arranged at low side inside crossbeam, and major axis II is arranged at inside crossbeam high-end; Sprocket wheel I is arranged at major axis I two ends, and sprocket wheel II is arranged at major axis II two ends; Between sprocket wheel I and sprocket wheel II, be provided with chain; Chain is provided with chain crawler belt; Described sprocket wheel II is groove sprocket wheel;
Described buffer gear comprises damper, and the plunger shaft of damper is arranged on respectively crossbeam inner side, and the extension bar of damper is connected with the groove of groove sprocket wheel.
In the time of unloaded of cargo, staff is placed in goods on chain crawler belt, due to the Action of Gravity Field of goods, moves to low side from the high-end of descending lifeline, thereby drives chain crawler belt to rotate, and then drive chain and sprocket wheel I and sprocket wheel II to rotate.In the time that sprocket wheel II rotates, and then the extension bar of the damper that is connected with groove of drive is along with impression orbit moves.Because the plunger shaft of damper is fixedly mounted on respectively crossbeam inner side, so the effect of damping is played in the now straight reciprocating motion of the extension bar of damper to sprocket wheel II, thereby the material on transmission device is played to the effect of buffering, make material arrive safe and sound workplatform or ground.
Sprocket wheel II described in the utility model can by common sprocket wheel and cam mechanism is combined forms, and also can adopt integrated processing technology to make.
The built-in needle bearing of groove of described sprocket wheel II, in the time that extension bar contacts with groove, can reduce friction, increases the service life.
The groove ovalize of described sprocket wheel II, is used in combination and plays speed governing effect with dashpot, realizes the slow of material and falls.
Described crossbeam low side is provided with tensioning groove, is provided with the bearing seat coaxial with major axis I in tensioning groove, is provided with bearing in bearing seat.Staff can be according to actual needs by adjusting the position of major axis I, realize chain and chain crawler belt carries out tensioning or loosens, chain is played a protective role, realize the axial rotation of major axis I simultaneously.
In like manner, major axis II two ends are provided with coaxial with it bearing seat, are provided with bearing in bearing seat, have ensured the axial rotation of major axis II.
In sum, the present invention has the following advantages:
1, the utility model improves traditional conveyor chain, and the structure after improvement becomes conveying crawler belt, has greatly increased the area of contact of goods and device, has reduced cliding friction and friction of rolling, and chain is connected with sprocket engagement, has improved safety factor;
2, the utility model groove ovalize, is used in combination and plays speed governing effect with dashpot, makes unloaded goods falling speed controlled, and slip velocity is remained in safe range, realizes the slow of material and falls;
3, the utility model is adjustable to the distance of sprocket wheel I, prevents that chain and chain from carrying out pine or tension, chain is played to the effect of overload protection;
4, the utility model is rational in infrastructure, reliable, easy to operate, is very beneficial for promotion and implementation.
