(54) САМОСВАЛЬНОЕ ТРАНСПОРТНОЕ СРЕДСТВО(54) DUMPING VEHICLE

1one

Изобретение относитс к саморазгружающимс механизмам и может быть использовано , в частности, в транспортных средствах дл механизированной выгрузки сыпучих грузов и жидкостей.The invention relates to self-unloading mechanisms and can be used, in particular, in vehicles for the mechanized unloading of bulk cargo and liquids.

Известен самосвал, содержащий самоходное шасси, опрокидывающийс кузов и гидроподъемник последнего, состо щий из поворотной рамки с гидроцилиндрами 1.A dump truck containing a self-propelled chassis, a tipping body and a hydraulic lift of the latter, consisting of a pivoting frame with hydraulic cylinders 1, is known.

Недостатком этого самосвала вл етс то, что груз выгружаетс при повороте кузова и загр зн етс выхлопными газами окружающа среда.The disadvantage of this dump truck is that the load is unloaded when the body is turned and the environment is polluted with exhaust gases.

Известно также самосвальное транспортное средство, содержащее размещенные на раме поворотный кузов с противовесом и фиксатор транспортного положени кузова 2.It is also known dumping vehicle containing swivel body mounted on the frame with a counterweight and locking the transport position of the body 2.

Недостаток такого транспортного средства состоит в сложности конструкции.The disadvantage of such a vehicle is the complexity of the design.

Цель изобретени - упрощение конструкции и уменьшение времени разгрузки.The purpose of the invention is to simplify the design and reduce unloading time.

Указанна цель достигаетс тем, что ось поворота кузова расположена в продольной вертикальной плоскости под углом 35-55° к продольной оси транспортного средства сThis goal is achieved by the fact that the axis of rotation of the body is located in the longitudinal vertical plane at an angle of 35-55 ° to the longitudinal axis of the vehicle with

наклоном к задней его части, а противовес закреплен в нижней задней части кузова.tilted to the rear, and the counterweight is fixed to the lower rear of the body.

На чертеже представлено самосвальное транспортное средство, общий вид.The drawing shows a dumping vehicle, a general view.

Самосвальное транспортное средство 5 содержит раму 1 и кузов 2, установленный на оси 3, котора закреплена на раме под углом 35-55° к ее продольной оси. На раме 1 закреплен подпружиненный фиксатор 4, взаимодействующий с ловителем 5, установленным на кузове 2. Кузов снабжен противовесом 6. фиксатор 4 соединен с т гой 7.Dump vehicle 5 includes a frame 1 and a body 2 mounted on axis 3, which is fixed to the frame at an angle of 35-55 ° to its longitudinal axis. The frame 1 is fixed to a spring-loaded latch 4, which interacts with the safety device 5 mounted on the body 2. The body is equipped with a counterweight 6. The latch 4 is connected to the thrust 7.

Устройство работает следующим образом.The device works as follows.

В исходном положении кузов 2 располагаетс горизонтально и закреплен фиксатором 4. В этом положении кузов 2 загружаетс материалом таким образом, чтобы центр т жести груженого кузова был над осью 3.In the initial position, the body 2 is positioned horizontally and secured with a latch 4. In this position, the body 2 is loaded with material so that the center of gravity of the loaded body is above axis 3.

Claims

For unloading, the body 2 is unlocked with the help of the cable 7. Under the action of the mass of the load 8, the body 2 begins to rotate on axis 3 to one side (in the direction on which there will be slightly more cargo in the body). The body and the load move at the same speed, however, this speed is not constant. It increases until the body passes a vertical position (optimal for emptying the load). From this point on, the load starts to pour out of the body, carried by centrifugal force, and the empty body speed decreases, but it is enough to continue the rotation by inertia and under the influence of the counterweight 6 to return the body 2 to its original position, to close it automatically with the lock 4 in the catcher 5 The center of gravity of the empty body will be below the axis 3. The latch 4 is performed by one of the known methods in the form of a spring-loaded rod with a roller, and the safety device 5 can be made in the form of two wedge-shaped supports. The proposed device is easy to manufacture and reliable in operation. It can be used as a stationary metering device. The application of the proposed device, for example, only on the transport of rock during the stripping work will give an economic effect of about 20 thousand rubles. Claims of the invention A dumping vehicle comprising a swivel body mounted on a frame with a counterweight and a locking body transport position, characterized in that, in order to simplify the design and reduce unloading time, the body turning axis is located in the longitudinal vertical plane at an angle of 35-55 ° to the longitudinal vehicle axles tilted to the rear, and the counterweight is fixed to the lower rear of | bodywork.
