Description

Hydraulic self-loading multifunction skip car

The utility model relates to a kind of hydraulic pressure self-charge type multifunctional turnover trolley.

At present, known self-charge type tip lorry collection dress, fortune, unload, itself is in charging hopper, transportation and three control positioies of discharging, having solved shipment unloads, but in fact this self-charge type tip lorry self-chambering effect is bad, can not adapt to the operation of various working conditions, can not self-chambering to some bulk materials, and at the part parts that in process of assembling, are easy to damage on the car, its reason is that this car self-chambering is to remove shovel dress bulk material by four wheel drive and ground generation friction force promotion hopper, because the loose material structure differs, the area of contact of hopper and bulk material is big, and the resistance of shovel dress is very big, so often cause four-wheel to skid, hopper can not insert among the bulk material, as will in bulk material, inserting the overwork that will produce driving engine or other parts, the damage that all might produce parts at any time by force, all can not self-chambering according to the self-charge type tip lorry of present more domestic manufacturer production, the period of service that has is long just have been damaged.

The purpose of this utility model; it is a kind of hydraulic pressure self-chambering multifunctional turnover trolley of development with functions such as hydraulic power self-chambering (overload protection device is arranged), transportation, discharging, lifting and passengers; it can also speed pull down the replacement fork truck with hopper, is used to load and unload the FCL material, realizes a tractor serves several purposes.

Main technical schemes of the present utility model is a kind of hydraulic pressure self-chambering multifunctional turnover trolley of design, being installed in the hopper elevating hopper from assembling device is installed on the elevator mechanism, control by hydraulic ram, liftable and tipping, this tip lorry is mainly by driving engine, the chassis, lifting mechanism, form from assembling device and hopper, its lifting mechanism is mainly by interior, housing and oil cylinder are formed, the relative housing of inside casing can move up and down under the effect of oil cylinder, outer frame bottom connects with the vehicle frame on chassis by bearing pin, the middle part connects with bearing pin with the piston rod hole of oil cylinder, when working, oil cylinder can make whole lifting mechanism rotate about 50 ° around outer frame bottom and vehicle frame point of attachment, hydraulic pressure passes through hinge-coupled bottom assembling device and hopper and fork truck, fork truck top connects with inside casing for whole, one of the tipping oil cylinder with fork after the bottom connect with bearing pin, the other end connects with bearing pin with the rear support of hopper, work by fluid control tipping oil cylinder, can make hopper about 40 ° around hinge axis, the principal character of this tip lorry is that two rotating shafts are inserted in two square holes up and down of rotation push pedal, be an integral body, can not relatively rotate after promptly rotating push pedal and rotating shaft assembling, square steel processing is adopted in rotating shaft, it is square that shape top, garden is processed in its bottom, be respectively charged in the hole circle of hopper both sides base plate, the hole circle is welded on the base plate of hopper both sides, two gears and tooth bar are put into the groove of intermediate rod bearing, again they are packed into the together top of rotating shaft, after rotating shaft aligns the middle square hole assembling of two gears, load onto two nuts, and then with the intermediate rod bearing by being bolted on the hopper, tooth bar connects by bearing pin with the piston rod of oil cylinder, the cylinder body afterbody be welded on the hopper upper bracket and connect with bearing pin, when piston rod moves right, tooth bar also moves right, two gears are under the effect of tooth bar, one right-hand revolution, one anti-clockwise rotation, two rotation push pedals are equally by a clockwise direction and anti-clockwise rotation, rotate to long and two-short dash line position among the figure, car load leaves forward, stop after hopper aimed at the bulk material adorned, operating hydraulically operated control cock, make the oil cylinder inner piston rod to left movement, at this moment rack drives gear and rotation push pedal rotation, one of them in the direction of the clock.A rotation counter clockwise, at this moment bulk material is pushed into hopper under the effect of rotation push pedal.Because the structure of loose material differs; when the first time, work was not filled; can repeat as stated above for the second time; for the third time; till filling; so just realized the purpose of hydraulic pressure self-chambering; in the hydraulic circuit of oil cylinder; a pressure-gradient control valve is installed; when the resistance of bulk material is very big; can pass through the pressure-gradient control valve overflow; be not damaged with part on the protection car; play the effect of overload protection; after hopper is filled loose material; after by lifting mechanism hopper being risen to certain altitude; make lifting mechanism and hopper recede about 45 ° together by dump ram; at this moment car load is in the transport position; after loose material is installed to the destination; handling dump ram is in vertical position lifting mechanism; handle oil cylinder again and make about 40 ° of hopper tipping; at this moment loose material is unloaded; the height that is unloaded can be adjusted in 2 meters scopes by lifting mechanism control hopper as required; for satisfying the needs of field work; this car design has 5 seats, and the field man can take this car to the building site, to reduce the fatigue of road; help increasing work efficiency; when needs shovel the article of packing case; hopper can be pulled down, oil cylinder and oil connector adopt hydraulic quick coupling and flexible pipe, at this moment can replace fork truck to use.

This hydraulic pressure self-chambering multifunctional turnover trolley has multiple functions such as self-chambering, self-unloading, transportation, lifting and carrying, also hopper can be pulled down as fork truck loading and unloading FCL material, realizes a tractor serves several purposes.This tip lorry adopts hydraulic operation, reliable operation, flexible operation is light, compact conformation, in light weight, oil consumption province, efficient height, can be widely used in build the road, workyards such as building, mine, factory, harbour, water conservancy, environmental sanitation, afforestation.
