Carriage side leakage preventing device for self-dumping semitrailer and using method of carriage side leakage preventing device

Abstract

The invention relates to a carriage side leakage preventing device for a self-dumping semitrailer and a using method of the carriage side leakage preventing device. The carriage side leakage preventing device comprises a vehicle head and a carriage; an automatic telescopic tent is arranged at the top end of the carriage; vertical rods are fixedly connected to the outer side of the automatic telescopic tent; first limiting switches are fixedly connected to the positions, close to the tail of the carriage, of the upper portions of the two sides of the carriage; second limiting switches are fixedly connected to the positions, located at the front end of the carriage, of the inner sides of the first limiting switches; supporting rods are fixedly connected to the upper portion of the left side of the carriage; a baffle is fixedly connected to the upper portions of the supporting rods; a fixing block is arranged on the upper portion of the interior of the carriage; and an electric telescopic rod is fixedly connected to the lower portion of the fixing block through a connecting plate. According to the carriage side leakage preventing device for the self-dumping semitrailer, through the above structure, the problem of environment pollution in the transportation process of sandy soil due to side leakage of the sandy soil because of jolting can be solved. Compared with an existing side leakage preventing device, the carriage side leakage preventing device is better in leakage prevention effect and is more convenient in operation.

Description

technical field [0001] The invention relates to a compartment side leakage prevention device for a self-unloading semi-trailer and an application method thereof, belonging to the technical field of engineering vehicles. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semi-trailer is generally a three-axle semi-trailer, and its types are divided into 11 meters. There are many kinds of 13-meter barns, low-bed semi-trailers, etc. It is a heavy-duty transportation vehicle that is connected to the head of the semi-trailer through the traction pin. Comprehensive economic benefits, transportation efficiency can be increased by 30-50%, costs can be reduced by 30-40%, and fuel consumption can be reduced by 20-30%. More importantly, the use of semi-trailers can also play a certain role in the organization of ...

Problems solved by technology

In the side leakage prevention device for a self-unloading semi-trailer of the present invention, after the sand is poured into the compartment, the control switch inside the front of the vehicle is turned on, at this time the drive motor and the electric telescopic rod start to work, and the drive motor drives the fixed block through the threaded rod Moving to the left, the top of the fixed block is fixedly connected to the inner side of the first awning rod through the fixed plate, the outer side of the automatic telescopic awning is fixedly connected with a vertical rod, and the inner side is fixedly connected with a first awning rod and a hinged rod, thereby driving the automatic telescopic awning and The vertical bar slides towards the rear of the compartment under the joint action of the slider, the chute, the slideway and the pulley. At the same time, the electric telescopic bar under the fixed block drives the bottom plate to move down to the position where the sand is raised, and the raised sand is moved to the raised position. The two sides of the carriage are pushed forward so that the height of sand and soil is lower than the height of the carriage. During the sliding process, when the limit block on the outer vertical plate of the automatic telescopic tent contacts the first limit switch, the control switch inside the front of the car is off. At this time, the drive motor and the electric telescopic rod stop working. At this time, the automatic telescopic tent is in a stretched state. At the same time, the electric telescopic rod starts to drive the bottom plate to move upward to maintain a compressed state. The driving motor starts to work, and the driving motor drives the fixed block to move to the front end of the compartment through the threaded rod and the sliding rod, and at the same time drives the automatic telescopic awning and the vertical rod to slide to the right under the action of the pulley, slider and chute. When the upper limit block touches the second limit switch, the control switch inside the front of the car is closed, so that the drive motor stops working, and the automatic retractable awning is in a compressed state, and is located under the sun visor, where the sun visor plays a role of sun protection. To protect the automatic retractable awning from being exposed to the sun, the right side of the carriage is lifted at this time, and the sand is discharged from the rear of the carriage. Through the above settings, the problem of environmental pollution caused by side leakage of sand due to bumps during transportation can be effectively solved. At the same time, the tarpaulin on the automatic retractable tent is made of waterproof material, which can ensure that the sand and soil will not be wet during transportation in the rainy season. When unloading, you only need to control the shrinkage of the tarpaulin through the control switch in the car to achieve an automatic effect. Compared with the previous side leakage prevention device, the side leakage prevention effect is better and the operation is more convenient
