Sand and stone transporting dump truck for building construction

Abstract

The invention discloses a sand and stone transporting dump truck for building construction. The sand and stone transporting dump truck comprises a frame and a dump truck carriage, the frame is fixedlyconnected with a cab, and the dump truck carriage is used for loading of sand and stone. The lower right end of the dump truck carriage is rotationally mounted at the upper right end of the frame through a first rotating shaft, the bottom wall of the dump truck carriage is provided with a mounting cavity with a downward opening, and reinforcing ribs extending bilaterally are longitudinally symmetrically arranged in the mounting cavity. Jacking hydraulic cylinders are longitudinally symmetrically mounted on the upper end face of the frame, jacking rods are fittingly mounted in the jacking hydraulic cylinders, and tail ends of the jacking rods are fittingly connected with the reinforcing ribs. Supporting blocks are longitudinally symmetrically arranged at the left end of the lower end wallof the frame and internally provided with bilaterally-communicated first slide grooves, and lock rods are slidably mounted in the first slide grooves. Fixing blocks are longitudinally symmetrically arranged at the left end of the upper end face of the frame and internally provided with bilaterally-communicated locking grooves matched with the lock rods, and translation hydraulic cylinders are symmetrically mounted on front and rear end walls of the mounting cavity.

Description

technical field [0001] The invention relates to the field of building material transportation, in particular to a sand and gravel transportation dump truck for building construction. Background technique [0002] In the process of building construction, sand and gravel materials are inseparable. Sand and gravel materials are the basic materials of construction projects. Sand and gravel can be used to make bricks and tiles, and can also be used to make concrete. Sand and gravel are generally transported by dump trucks. The dump truck is a special short-distance material transport vehicle with a tiltable hopper. After the dump truck transports the sand and gravel to the desired location, it needs to lift up one side of the dump car using the jacking device to tilt the dump car. , so as to facilitate the sand and gravel to slide down from the dump car, but when the dump car is tilted, the center of gravity of the entire car body will be shifted to the rear of the car, and becau...

[0002] In the process of building construction, sand and gravel materials are inseparable. Sand and gravel materials are the basic materials of construction projects. Sand and gravel can be used to make bricks and tiles, and can also be used to make concrete. Sand and gravel are generally transported by dump trucks. The dump truck is a special short-distance material transport vehicle with a tiltable hopper. After the dump truck transports the sand and gravel to the desired location, it needs to lift up one side of the dump car using the jacking device to tilt the dump car. , so as to facilitate the sand and gravel to slide down from the dump car, but when the dump car is tilted, the center of gravity of the entire car body will be shifted to the rear of the car, and because the sand and gravel have a certain viscosity, the sand and gravel are not easy to go down when the dump car is tilted Sliding, thus, it is easier to cause the cab to be lifted up, which is easy to cause damage to the driver and the car body. Therefore, the traditional gravel dump truck has great disadvantages and potential safety hazards.
