Abstract
Can realize bucket -wheel stacker reclaimer hydraulic pressure trailer of partly lying prone of accurate location of machinery, including rail wheel, frame, tightening band bracket, a change width of cloth belt bracket, complete machine displacement drive mechanism, a change width of cloth hydraulic cylinder drive system, the improvement of doing is: stretch over an arc door frame that becomes width of cloth belt bracket to the installation of strain amplitude belt bracket position in the frame, correspond arc door frame and go up bar hole rigidity through shaft on becoming width of cloth belt bracket, at through shaft both ends difference fixed stop, install the fender roller of roll extrusion on the portal side column on the baffle, become a width of cloth belt bracket top dead center position in portal upper end and establish and become width of cloth belt bracket locking couple, become that one installation becomes a width of cloth pneumatic cylinder between width of cloth belt bracket and the frame. The utility model discloses an actively the effect is: the not synchronization issues of two hydro -cylinders among the prior art has been eliminated. Guarantee becoming width of cloth belt bracket and facing upward the in -process of bowing single hydro -cylinder adjustment and do not have card and hinder, the locking couple has prevented and has become that a belt bracket is operating to sink.
Description
Technical field
This utility model belongs to field of work machines, is specifically related to large-scale scattered stockpiling in stock ground, the supporting trailer of feeding transmission bucket-wheel stacker reclaimer。
Background technology
Large-scale bulk cargo field use by rail wheel, the frame that rail wheel supports, the rack-mounted fixing bracket one section of belt being maintained in the oblique angle of setting, convert one section of belt elevation-depression angle the luffing bracket being connected mutually with fixing bracket, luffing hydraulic cylinder between luffing bracket and frame, rack-mounted complete machine moving drive mechanism, the hydraulic pressure of hydraulic cylinders drive system composition is partly lain prone trailer, it it is current domestic and international each power plant, harbour etc. is matched in bucket-wheel stacker reclaimer and realizes windrow and the comparatively conventional a kind of trailer of the two-way conveying of feeding of turning back, there is control simple, stock ground utilization rate high, along with Hydraulic Elements transmission and control level improve constantly and the increasing of degree domestic, user selects hydraulic pressure partly to lie prone the more and more of trailer。With the expansion making consumption, shortcomings used more thereon reveal gradually, and in operation, the head of trailer sinks, and is a commonplace problem, normal operation is had a negative impact。Next to that when driving two oil cylinders of luffing frame to run, it is difficult to keep permanent and synchronize, two oil cylinders asynchronous, can produce to destroy internal force on equipment。And in the prior art, solve two oil cylinders and keep precisely synchronization also relatively difficult in prolonged and repeated use。In recent years, owing to increase and some harbour facilities of Power Plant also begin to select this trailer form, promote this trailer need to adapt to material variety and scope of exerting oneself also is widened gradually, cause that the problems referred to above can be more serious, therefore no matter improvement should be optimized from serviceability and the economic indicator everyway of this trailer so that it is meet the new demand in market。
Summary of the invention:
The purpose of this utility model is to provide a kind of bucket-wheel stacker reclaimer hydraulic pressure realizing machinery precise positioning and partly lies prone trailer, overcomes this kind of trailer above shortcomings in prior art。
The frame that this utility model includes rail wheel, rail wheel supports, rack-mounted fixing belt bracket, luffing belt bracket, rack-mounted complete machine moving drive mechanism, luffing hydraulic cylinders drive system；Improvements introduced is: in frame, strain amplitude belt bracket locations is installed with luffing belt bracket hinge be the center of circle, across the arc door frame of luffing belt bracket, arc door frame side column longitudinally on have cylindrical void；The fixing through shaft in bar hole position on corresponding arc door frame on luffing belt bracket, stretches out the two ends fixed dam respectively of door frame side column in through shaft from bar hole, installs the block roller being rolled on door frame side column on the baffle plate often held；Set luffing belt carriage lock hook at door frame upper end luffing belt bracket top dead center position, locking hook is installed between door frame and hook luffing belt bracket entered hook and unhook driving mechanism；One luffing hydraulic cylinder is installed between select location and the frame on luffing belt bracket longitudinal midline。
Of the present utility model having the benefit effect that adjusts luffing belt bracket with an independent oil cylinder, eliminates the asynchronous problem of two oil cylinders in prior art。The bindiny mechanism of the arc door frame set up and door frame and luffing belt bracket, ensure that luffing belt bracket faces upward homeostasis of keeping tie in the process of bowing without jam in single oil cylinder adjustment, set up in arc door frame upper end and stable for the luffing belt bracket locking at top dead center position is linked up with, the operating sinking preventing luffing belt bracket to cause because of oil cylinder pressure release, keeps the operating position that it is stable。In addition the minimizing of hinge structure oil cylinder number, except saving an oil cylinder, reducing hydraulic pressure pump delivery, also reduces and controls the valve group that oil cylinder synchronizes, and decreases the artificial input of frequently adjustment。

Detailed description of the invention
Consult Fig. 1, the frame 2 that this utility model includes rail wheel 1, rail wheel supports, rack-mounted fixing belt bracket 3, luffing belt bracket 4, rack-mounted complete machine moving drive mechanism 5, luffing hydraulic cylinders drive system；Strain amplitude belt bracket locations is installed by frame with luffing belt bracket hinge be the center of circle, across the arc door frame 6 of luffing belt bracket, the door pillar of door frame 6 channel-section steel that two openings are opposing is constituted, and arc door frame side column longitudinal direction has cylindrical void 7；The fixing through shaft 8 in bar hole position on corresponding arc door frame on luffing belt bracket。
Consult Fig. 2, Fig. 3, the two ends fixed dam 9 respectively of door frame side column is stretched out from bar hole in through shaft, on the baffle plate often held in two block rollers being rolled on door frame side column 10 mounted above and below of through shaft cross section projection, baffle plate 9 and block roller 10 groove on the channel-section steel of composition door frame side column。
Consult Fig. 4, the luffing belt carriage lock hook 11 that can catch on through shaft 8 is installed at door 6 upper end luffing belt bracket top dead center position, locks hook DT type electric pushrod 12(straight stroke electric actuating mechanism) control the unhook of locking hook 11 relative through shafts 8 and enter hook。Electric pushrod 12 luffing belt bracket locations detecting element and electric controller drive。One luffing hydraulic cylinder 12 is installed between select location and the frame on luffing belt bracket longitudinal midline。
