Abstract
The present invention belongs to the field of vehicle throw-off technology, in the concrete, it relates to a scraper blade type self-unloading device. It is composed of hydraulic driving device and scraper blade sliding device. Its application range is extensive, performance is reliable and operation is simple.
Description
Technical field
The present invention relates to the automatic discharging gear of a kind of automobile, particularly relate to a kind of heavy duty truck scraper plate and unload bulk material device automatically.
Technical background
Domestic Automotive Industry was in develop rapidly in recent years, and what show in the heavy duty truck field is particularly outstanding, and its development tendency is maximization, heavy-duty, and load-carrying ability has also obtained soaring rapidly.Original like this self-unloading device has not caught up with the development of heavy duty truck, and outstanding behaviours is in the full self-unloading of hanging series and lengthening semi-mounted series heavy duty truck series of four, five and six.Use inclination unloading, the vehicle body poor stability can cause malignant lesion to tire when the hard band of bulk cargo is sharp; Sometimes tire can be filled by goods down after unsnatching bulk cargo, to such an extent as to car body is difficult to get away.Sometimes also do not slide to the certain angle bulk cargo when the car body inclination, then can cause the serious consequence of car load rollover.Certainly the technology of turning over makes the problems referred to above obtain solution after using, but brought even more serious problem simultaneously again, when after the technology of turning over when being used for that four, five and six are complete to hang series and lengthening semi-mounted series heavy duty truck at the bottom of the car body at the bottom of skeleton and the car body between skeleton and the crossbeam twisting be in and will be subjected to great instantaneous moment when unloading bulk cargo, therefore the length, the load-carrying capacity that overturn of back all has been subjected to strict restriction, also have simultaneously when unloading after overturning envelope platform be raised to certain angle after the bulk cargo serious consequence that then can cause headstock to swing back when also failing landing.
Summary of the invention
In order to overcome the prior art above shortcomings, the invention provides a kind of heavy lengthened trailer scraper plate self-unloading device, this invention can guarantee the stability and the fastness of vehicle body, do not change the force structure of vehicle body main body, it is advantageous that this self-unloading device does not limit bodywork length, the restricting vehicle load-carrying capacity can not guarantee the leakproofness in compartment simultaneously yet and unload back noresidue bulk cargo.
The technical solution adopted for the present invention to solve the technical problems is: the upper end at both sides, compartment side shield 2,39 connects back shield 1 with bearing pin 11; The scraper plate carriage is set formed two of the left and right position-limited trough 42,40 of cabin floor 44 and 12 both sides, middle ridge, both sides, compartment side shield 2,39 bottoms in getting on the right track respectively, every cover scraper plate carriage is made of two groups of chains 4, front scrapping plate 5 middle scrapers 6 and back scraper plate 7 are that one group of front scrapping plate 5 and middle scraper 6 connect firmly on every group of chain 4 separately for another group, and every group of chain 4 all is meshed with tail wheel 13,48,51,52.
Described tail wheel 13,48,51,52 is a drive wheel, tail wheel 13,48,51,52 is installed on the left and right tail- gear spindle 18,50, left and right tail- gear spindle 18,50 is fixed on the cabin floor framework beam 16 by bearing support 19, HM Hydraulic Motor 46 is installed on the HM Hydraulic Motor support 47, the output shaft of HM Hydraulic Motor 46 connects left tail-gear spindle 18, right tail-gear spindle 50 connects with left tail-gear spindle 18 by coupler 49, on above-mentioned HM Hydraulic Motor 46, coupler 49 and left and right tailing axle 18,50 U type protective cover 53 is set.
Left and right great wheel 8,29 is installed on the left and right great wheel axle 31,28, the two ends of left and right great wheel axle 31,28 are separately fixed on the left and right travel(l)ing rest 32,30, adjust screw rod 21,25,26,27 and be threaded, on each travel(l)ing rest 32,30 lock nut 24 is set with the two ends of travel(l)ing rest 32,30.
The space that is surrounded at cabin floor skeleton longeron 37,41,15, cabin floor framework beam 16 downsides and floor stringer crossbeam 3 upsides is the lower railway of scraper plate carriage; Both sides and floor stringer crossbeam 3 upper surfaces at cabin floor skeleton longeron 37,15 inboards, cabin floor skeleton longeron 41 are installed scraper plate track 43,45,55,54.
The upper end of back shield 1 left and right sides is welded two swing handles 34 respectively, is fixed in the compartment rear side with bearing pin 11 for axle, and each swing handle 34 end is by the piston rod 35 of bearing pin 33 connection hydraulic actuating cylinders, and the lower end of back shield 1 is provided with locking card 36.
The invention has the beneficial effects as follows: the present invention is simple in structure, dependable performance, safety performance are good, and the energy-and time-economizing unloading is quick.Simultaneously, what goods carrying vehicle can stability and safety unloads bulk goods, leaves the goods yard easily after unsnatching goods, does not stop other vehicle, also avoids the generation of serious accidents such as blowing out simultaneously.
