This technical conceive belongs to bulk material pile, the taking equipment field in the Work machine.
In industrial sectors such as some electric power, metallurgy, relate to a large amount of diffusing material (coal, ore etc.) stacking and extract operation.The major equipment of currently finish bulk material pile, getting operation is gate-type bucket-wheel stacker, reclaimer in China, the door frame that it mainly is made of two side stands and entablatrance, the moved cross beam of lifting in door frame, be installed in moved cross beam heap, get material belt feeder and bucket wheel, and be connected the compositions such as trailer of moved cross beam and system's belt feeder.Its windrow working process is: trailer will receive the bulk cargo of coming and be transported to the heap that is installed in moved cross beam top through the trailer belt feeder from the conveying system beyond this equipment, get on the material belt transporter, be transferred to the heap that can vertically move along crossbeam that is located at the moved cross beam bottom by this belt feeder again, get on the material belt feeder, by moving of this belt feeder along beam, the lifting of crossbeam, it is comprehensive that the moving of whole equipment just can be realized, the blanking of low head, the process of getting material is: bucket wheel rolls and shovels material, material is extracted the heap on moved cross beam top, get on the material belt feeder, be transferred to the heap of bottom again by this belt feeder, get on the material belt feeder, at this moment the movably heap of crossbeam bottom, get the end that the material belt feeder is fixed on moved cross beam and trailer linking.By this belt feeder bulk cargo is left on the trailer belt feeder, by the trailer belt feeder bulk cargo is transferred to again and transports the materials place on system's belt feeder to, pile as can be seen by above narration, the motion of bulk cargo is a positive inverse process in the material extracting operation, on in these two processes in the portable beam, the no much variations of relative control position relation between the following belt feeder, just the belt feeder of bottom its mouth when windrow is being intended on the blanking position, belt feeder is fixed on moved cross beam one end near trailer when getting material, but at heap, get in two kinds of work of material, the relation between trailer and the moved cross beam is just different.Trailer will leave bulk cargo heap on moved cross beam top, get on the material transmission belt machine during windrow, the trailer head will be higher than portable beam internal upper part belt feeder, get when material bulk cargo will be by the heap of bottom in the moved cross beam, get the material belt feeder and send here and leave on the trailer belt feeder, here just relate to a trailer and portable beam relative position transformation problem, just the trailer head is wanted ascending, descending, forward and back.On the product that has recently, get material and do not use bottom belt feeder in the moved cross beam, this belt feeder is exclusively used in blanking, and be convenient to observe blanking like this outside being installed in the moved cross beam below, accept supplied materials and a belt feeder of close crossbeam in the moved cross beam and trailer cohesive end is tiltedly stretched to another below, belt feeder end down, just can be transported to the material that the scraper bowl of overall beam scope shovel comes one end of close trailer.But this situation still needs the evolution of trailer head, realizes that the mode of the conversion of the relative crossbeam of trailer has had several forms at present.Fairly simple is directly to hang the trailer head with steel rope.But because equipment itself is huge, with the non-rigid connection of steel rope, the running orbit controllability is poor in the conversion process, moves steadily not inaccurate.The nearest a kind of reliable revolving ring type trailer evolution mechanism that occurs.Its basic structure is to establish a relatively crossbeam tumbler ring with respect to the outside of trailer head with external circular formula at moved cross beam, the trailer head is hinged on the annulus, drive the positive de-rotation of annulus, can realize the lifting and the advance and retreat of the relative crossbeam of trailer head.This version is fairly perfect, but and in the past structure need by comparison more than the member of retrofit, and have also very huge, more than be the present situation of prior art.
The objective of the invention is to have under the situation of good controllability in guaranteeing trailer head position conversion process, simplified structure makes it to be easy to make, and reduces investment.
Main composition of the present invention is on moved cross beam and the end fixed installation arc-shaped rail groove of trailer linking.The slide block or the roller that can move in rail groove is installed in trailer head both sides.Turn over from positive and negative both direction wheel with steel rope or chain and to affect the trailer head.Can realize trailer head evolution on demand.
Using good effect of the present invention is to have under the prerequisite of good controllability in guaranteeing trailer head conversion process, has simplified equipment, and the member that is adopted is easy to processing, assembling and maintenance.
Accompanying drawing 1 is the overall schematic of this technical conceive;
Accompanying drawing 2 is that local structure figure is looked on the slide block of trailer head in the rail groove of accompanying drawing 1 or the section left side of roller present position.
Each member annexation of the present invention and the course of work are to adopt the crossbeam in original technology, (1 among Fig. 1). Belt feeder in the crossbeam can transfer to the stockplling belt machine with accepting from the defeated next bulk cargo of trailer and will deliver to the movable transverse beam-ends from the bulk cargo that bucket wheel is fetched and throw Go out. Among Fig. 1 and Fig. 22 is for being fixed on more than half circular arc rail groove of moved cross beam end. This rail groove is symmetrical arranged two. Article two, the groove of rail groove is inwardly relative. Article two, the distance of track is equivalent to the width of trailer framework, makes in the groove that the slide block that is installed in trailer head frame both sides or roller stretch into rail groove. In the accompanying drawing 13 is the trailer head. Among Fig. 1 and Fig. 24 is for being installed in slide block or the roller in the orbital groove of stretching on the trailer head frame. Among Fig. 1 and Fig. 25 is steel wire rope or chain idler pulley, this idler pulley arranges several along rail groove circular arc inboard, in order that the steel wire rope that passes through or chain are supportted into one and the approximate circular arc of rail groove, basic identical to realize rope traction force direction and slide block traffic direction. Among Fig. 16 is the arrangement for controlling of steel wire rope or chain, and it is the reel of a Wound steel rope being driven by reductor or the sprocket wheel that affects chain. Among Fig. 1 and Fig. 27 is steel wire rope or chain, and its centre is fixed on the drive unit 6, two ends is fixed on the slide block 4 again, and whole steel wire rope forms one and walk around the closed ring that idler pulley connects trailer and drives reel. Owing to be blanking channel between two rail grooves, do not allowed member to exist, thereby haulage cable can only be in both sides.
