Swinging arm translation roof system of a dregs truck

Abstract

The invention discloses a swinging arm translating roof system of a dregs truck, including carriages, Top cover and top cover lifting device, A lifting device of that top cover is of a four-link structure, comprises two driven arms and two driving arms, Two driven arms and two driving arms are symmetrically inclined on the left and right sides of the vehicle compartment, the upper ends of each driven arm and the driven arm are respectively connected with the top cover through the first pin shaft, the lower ends of the two driving arms are respectively connected with the two ends of the drivingarm through shaft, and the lower ends of the two driven arms are respectively connected with the two ends of the driven arm through shaft; The driving arm through shaft and the driven arm through shaft are fixedly installed at the bottom of the car; A swivel arm and an oil cylinder are respectively arrange on two sides of that car bottom, each oil cylinder is arrange on a corresponding oil cylinder seat at the car bottom, one end of each swivel arm is welded with a driving arm on the same side, and the other end of each swivel arm is connected with a push rod of the oil cylinder on the same side through a second pin shaft. The invention ensures the sealing of the carriage after the dregs truck is loaded with goods, and avoids the leakage of materials and dust in the transportation processof the truck.

Description

Technical field [0001] The invention relates to the field of muck truck transportation, in particular to a swing arm type translational roof system for muck trucks. Background technique [0002] With the urbanization process and the continuous economic development of all parts of the country, the scale of cities has continued to expand and the urban population has grown rapidly. The accompanying urban domestic waste, construction waste, and the transportation of sludge from urban construction have also increased unprecedentedly. The slag truck currently in use generally carries materials such as coal (powder), ore (powder), soil, construction waste, river sand and other materials. The transported goods contain a large amount of powder, and a large amount of dust is generated from the cargo compartment during the driving of the vehicle, resulting in a large amount of dust in the air, causing serious pollution to the environment. Although the country has issued regulations that s...

AI Technical Summary

Problems solved by technology

The transported goods contain a large amount of powder, and the vehicle generates a large amount of dust flying out of the cargo compartment during driving, resulting in a large amount of dust in the air, causing serious pollution to the environment

Although the country has promulgated regulations that this type of slag truck must have a cover, the existing cover is not effective in covering it. It is simply covered with a piece of earthen cloth, but due to the lack of airtightness, the blocking effect is not good. The phenomenon of dust and leakage along the way is serious, causing secondary pollution and damage to the urban environment; moreover, during the operation of the muck truck, since the earthen cloth is not only connected to the carriage at the four corners, it is easy to fill the air and the resistance increases

[0003] At present, most of the lifting mechanisms for the roof of muck trucks on the market have the lifting arm placed inside the roof, so that during the closing process, the lifting arm is easy to contact with the muck, which will not only damage the lifting arm, but also cause the top Lid does not close tightly
