Description
Technical field
The invention belongs to logistics equipment field of mechanical technique, particularly a kind of driving at track-type transporting vehicle, turn to and become the device of rail.
Background technology
In current domestic automatic Material Handling System, existing rail materials handling vehicle is as: linear reciprocating shuttle, single track annular shuttle, the aerial shuttle of single track annular etc.Linear reciprocating shuttle adopts single motor to drive, and on biserial track, reciprocating linear travels, and does not turn to and becomes rail driving functions.Linear reciprocating shuttle, because reciprocating linear is walked, can be brought into play very high efficiency to simple straight line carrying.But the carrying demand that can not be competent at the many cars of system and pahtfinder hard.Single track annular shuttle adopts Dual-motors Driving, along single-row track annular, travels, and can turn to along track, but not possess the turnout driving functions that switches tracks.Because dolly moves along single track, while moving many cars in system, for fear of collision each other, the empty race rate of bicycle is higher.Two cover control system realize Dual-motors Driving, have not only increased the cost of bicycle, have also increased the quality of car load, and under many cars environment, energy consumption is uneconomical.The annular aerial shuttle of single track can, along hanging skyborne track under single motor drives, turn to and become rail and move.Dolly self is not with and is become rail function, and at fork, by the switching of switch winding machine track, dolly completes and becomes rail operation along the track having switched.Because each fork all needs switch mechanism is set, increased the complexity of rail system, be unfavorable for expansion and the change of rail system.
Also have in addition a kind of track-type transporting vehicle poor by the speed of two motors of control, realize transport trolley drives on biserial track, turn to, become rail driving functions, owing to there is error in the fabrication and installation of track, there is inevitable deviation in the theoretical radius that control system is calculated and actual orbit radius, the speeds match of two motors lacks absolute reference frame, therefore it is higher to control difficulty, mechanical wear is large, adopt two motors of two cover servo system controls, not only increased manufacturing cost, the deadweight of transport trolley is corresponding increase also, the economy of using is also optimized not, and very difficult satisfied running at high speed and the requirement of flow carrying greatly.
Summary of the invention
The object of the invention is for overcoming the defect of prior art, design a kind of quality light, cost is low, can realize that smoothness is travelled, low wearing and tearing, high reliability, and can meet in rail system complicated and changeable many cars simultaneously high-speed cruising demands driving, turn to, become the driver train of the track-type transporting vehicle that rail travels.
The driver train of track-type transporting vehicle of the present invention, by supporting framework unit, driver element and servo-actuated cell formation, driver element and being coupled together by supporting framework unit with moving cell, supporting framework unit upper, driver element block bearing and servo-actuated unit bearing bearing are housed respectively in lower longeron, 4 the first track adjusting wheels of driver element are installed on respectively four angles of drive installation framework, 2 the first row travelling wheels, single-power actuating device, drive installation framework and being installed on driver framework with the first track selecting arrangement of four rolling, upper on driver framework, the first axis of revolution is equipped with respectively in lower end, on in the first axis of revolution and supporting framework unit, driver element block bearing in lower longeron connects, 2 the second road wheels, 4 the second track adjusting wheels, servo-actuated installation frame and forming with moving cell with the second track selecting arrangement of four guide wheels, 4 the second track adjusting wheels are installed on respectively four angles of servo-actuated installation frame, the second road wheel and the second track selecting arrangement are installed on servo-actuated installation frame, on in the second axis of revolution and supporting framework unit, servo-actuated unit bearing bearing in lower longeron connects, with 2 the second road wheels of moving cell and 2 the first row travelling wheels of driver element, form the four-wheel of transport trolleys.
Single-power actuating device of the present invention is the single-power actuating device with differential function.
When vehicle operating, the single-power actuating device in driver element with differential function drives two road wheels to rotate, for transport trolley provides the power that advances or retreat, be positioned at driver element and to driver element with moving cell, keep straight on and the guiding of turning travel direction respectively with 8 track adjusting wheels of moving cell, differential gear in driver element can be according to the actual conditions of track, the rotating speed of 2 road wheels is carried out to adjustment constantly, with 2 road wheels in moving cell, following two road wheels of driver element rotates, under the effect of track adjusting wheel, according to track, automatically carry out the poor coupling of speed.When through fork, driver element and with the track selecting arrangement being equipped with respectively in moving cell with four rolling, track selecting arrangement is pushed into guide wheel one side of required walking, wherein 2 rollers along the guide edge on track and be positioned at driver element, with the effect of 2 track adjusting wheels of moving cell, successively make driver element, with moving cell, pass through smoothly turnout, thereby complete turnout craspedodrome or the transition action of whole transport trolley.
The novel driving of rail type transport trolley, turn to, become rail mechanism owing to adopting driver element, being connected separately independent rotation with supporting framework unit by swing bearing with moving cell, in the design of track, can use less Turning radius, save space, to the larger elasticity of Track desigh increase.Transport trolley self is with path direction selecting arrangement, and track selecting arrangement, without arranging and pull rail mechanism in orbit, has reduced the complexity of Track desigh, has reduced the cost of track, is conducive to change and the expansion of rail system.Driver element, with moving cell, all have with track curvature and change and to adjust constantly the poor function of wheel speed, reach the track actual curvature perfect matching poor with wheel speed, reduce mechanical wear, reliability and the service life of raising transport trolley.With the single-power driver element of differential, adopt a power to realize the driving of four-wheel transport trolley, reduced the complexity of controlling, reduced the probability that fault occurs, give full play to electrical efficiency.Driver element, relatively independent and symmetrical with moving cell and transport trolley center, can be according to track uphill, downhill situation, to adopting f-w-d or back-wheel drive to select flexibly during design vehicle.Can also, according to the situation of logistics system, different transfer mechanisms be installed in supporting framework unit.
Structure simple of the present invention, controls difficulty little, can effectively improve rail type conveyor system work efficiency, reduces fault rate, improves system reliability of operation.Use the present invention, can also greatly reduce the complexity of Track desigh, realize orbit modification and expansion cheaply.
