A kind of belt frame loader
Technical field
The utility model relates to a kind of machinery that frames up, and particularly a kind of floor area is little, the belt frame loader that frames up stable.
Background technology
The belt frame loader is made up of a series of special load-transfer devices, and the load-transfer device spacing can be designed to 1000 ~ 1200 millimeters as required, and bench board can be designed to random length as required, and cost is directly proportional with length basically.Present extruded threads rear portion disposal system degree of automation is low, and manpower labour intensity is big, the large-scale extruded threads of domestic especially in recent years high speed development; Product weight increases greatly; And the product type complicacy is various, is impossible by a dead lift, and special hanger solves the labour intensity problem to a certain extent; But efficient is low, and it is big to take resource.The automatic frame loader of traditional crane type increases along with length and becomes very huge, increases cost of investment greatly.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of floor area little, the belt frame loader that frames up stable.
The utility model solves the technical scheme that its technical matters adopted:
A kind of belt frame loader comprises support, is provided with messenger chain in the support; Said messenger chain matches with tooth bar guide wheel and conveying arm guide wheel respectively; The support top movable is equipped with tooth bar, and tooth bar and tooth bar guide wheel are meshing each other, and support is provided with and is transferred the conveying arm that arm guide wheel guiding can be moved along support; Conveying arm is set with belt conveyor outward, is provided with one-way driving mechanism between said belt conveyor and the tooth bar;
As the improvement of such scheme, described one-way driving mechanism comprises that the horizontal motion with tooth bar is converted into the intermediate gear of rotation, is provided with driving pulley between said intermediate gear and the belt conveyor;
As the further improvement of such scheme, described driving pulley set inside has gear, is provided with unilateral bearing in the middle of the gear, and unilateral bearing links to each other with the imput shaft of its set inside.
The beneficial effect of the utility model is: this novel band frame loader matches with tooth bar guide wheel and conveying arm guide wheel respectively controlling the synchronous motion of conveying arm and tooth bar respectively through messenger chain, and one-way driving mechanism is set between belt conveyor and tooth bar, when making the conveying arm that has belt conveyor hold section bar to be sent to the material frame; Belt conveyor is motionless, and when conveying arm was retreated, belt conveyor is transmission forward; And the speed of conveying arm equals the astern speed of conveying arm relatively, and in the opposite direction, promptly the relative ground of belt is static; Section bar rests on material frame top; Retreat along the inclined-plane of its head and fall into the material frame at leisure along with conveying arm, greatly reduce labour intensity, and the frame loader volume of the utility model is little; Cost is low, the efficient that frames up height.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front elevation of the utility model;
Fig. 2 is the connection structure cutaway view of the utility model.
The specific embodiment
With reference to Fig. 1 ~ 2, a kind of belt frame loader comprises support 1; Be provided with messenger chain 4 in the support 1, said messenger chain 4 matches with tooth bar guide wheel 2 and conveying arm guide wheel 12 respectively, and support 1 top movable is equipped with tooth bar 11; Tooth bar 11 is meshing each other with tooth bar guide wheel 2; Support 1 is provided with and is transferred the conveying arm 3 that arm guide wheel 12 guiding can be moved along support 1, and conveying arm 3 is outer to be set with belt conveyor 7, is provided with one-way driving mechanism between said belt conveyor 7 and the tooth bar 11.
Described one-way driving mechanism comprises that the horizontal motion with tooth bar 11 is converted into the intermediate gear 10 of rotation, is provided with driving pulley 6 between said intermediate gear 10 and the belt conveyor 7.
Described driving pulley 6 set inside have gear 8, are provided with unilateral bearing 9 in the middle of the gear 8, and unilateral bearing 9 links to each other with the imput shaft 5 of its set inside.
This novel band frame loader matches with tooth bar guide wheel 2 and conveying arm guide wheel 12 respectively through messenger chain 4 and is synchronized with the movement with tooth bar 11 to control conveying arm 3 respectively, and one-way driving mechanism is set between belt conveyor 7 and tooth bar 11, makes the conveying arm 3 that has belt conveyor 7 hold section bar and is sent to when expecting frame; Belt conveyor 7 is motionless; When conveying arm 3 is retreated, belt conveyor 7 transmission forward, and the speed of relative conveying arm 3 equals the astern speed of conveying arm 3; In the opposite direction; Be that the relative ground of belt is static, section bar rests on material frame top, along with conveying arm 3 is retreated along the inclined-plane of its head and fallen into the material frame at leisure.
The propulsion source that the power that belt conveyor 7 rolls is forward retreated from conveying arm 3 through the rack-and-gear transmission, therefore only needs a motor just can accomplish two actions.This design can be saved cost on the one hand, is through this mechanical drive mode on the other hand, guarantee belt conveyor 7 forward the speed of transmission equal the astern speed of conveying arm 3, the relative ground of section bar was static when conveying arm 3 was retreated; The design also adds unilateral bearing 9 between gear and transmission shaft, when conveying arm 3 is advanced, and unilateral bearing 9 not transmissions, belt conveyor 7 relative conveying arms 3 are static, so section bar is fed forward; When conveying arm is retreated, the unilateral bearing transmission, relatively face is static to make belt conveyor 7 rolling section bars.
Certainly, the utility model is not limited to above-mentioned embodiment, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
