Carriage sealing device and muck vehicle

Abstract

The invention relates to a carriage sealing device. The carriage sealing device comprises a carriage body, a sliding assembly and a transmission assembly, wherein the sliding assembly is arranged on the carriage body. The sliding assembly comprises a guide rail and a plurality of sliding vehicles arranged on the guide rail. The sliding vehicles comprise tail trolleys which are close to the tail portion of a carriage body of a carriage. The carriage sealing device is characterized in that the carriage sealing device further comprises a tail buckling assembly; the tail buckling assembly comprises shifting forks, tail shed frames and shifting fork pin shafts, the shifting fork pin shafts are arranged on the outer sides of the tail sliding vehicles, and the shifting forks can be rotationally arranged on the shifting fork pin shafts in a sleeving mode; the upper ends of the shifting forks are connected with the tail shed frame, and the lower ends of the shifting forks are provided with U-type fork openings; and the tail portion of the carriage body of the carriage is provided with a fixing shaft, and the fixing shaft can be inserted into or disengaged from the U-type fork openings. Theinvention further discloses a muck vehicle with a good sealing shed cover. The muck vehicle comprises the carriage sealing device. The carriage sealing device and the muck vehicle have the beneficialeffects that the sealing device is stable in structure, smooth in opening and closing, good in sealing effect, convenient to operate, firm in locking and small in size after being stored.

Description

Technical field [0001] The invention relates to the technical field of box body sealing of transportation vehicles, in particular to a compartment sealing device, and also to a muck truck. Background technique [0002] Dump trucks, also called earth-pull trucks and slag trucks, do not specifically refer to any type of truck, but rather a truck whose purpose is to transport construction materials such as sand and gravel. Muck trucks are more common such as large dump trucks, which are mostly large trucks. Muck trucks are mainly used for loading, unloading and transporting the earth, sand, gravel and construction waste required for urban infrastructure and real estate construction. Vehicles loaded with goods are prone to leakage, dust, and odors during driving, which cause serious pollution to the urban environment. It is easy to cause traffic accidents and seriously affect the lives of residents. [0003] Faced with many environmental protection problems such as “dirty trucks” wal...

AI Technical Summary

Problems solved by technology

Muck trucks are mainly used for loading, unloading and transporting earthwork, gravel and construction waste required for urban infrastructure and real estate construction. Vehicles fully loaded with goods are prone to leakage, dust, and peculiar smells during driving, causing serious pollution to the urban environment and causing serious damage to the urban environment. It is easy to cause traffic accidents and seriously affect the lives of residents

[0003] Faced with many environmental protection problems such as "dirty trucks" running on the road in the city, the environmental protection department has issued a series of management measures. The cover is heavy, requires high hydraulic system, requires high assembly precision, is easy to damage, and has a high failure rate, resulting in low vehicle attendance; the tarpaulin cover system in the form of wire rope or chain transmission used in muck trucks is a good solution. The front part of the compartment is dusty, but the rear part cannot be completely closed

Although some carriages use inclined shed poles at the rear, and there are hanging curtains on the inclined shed poles, during the normal operation of the vehicle, due to imperfect technology, the shed poles will be reset, and the shed poles and hanging curtains will be opened at any time due to the wind force. , the dust is still there, and the sealing effect of the snap-fit ​​cannot be achieved; especially when the vehicle is bumping, the material blocks will be scattered, which will not only cause pollution, but also cause road safety hazards

Therefore, dust leakage at the rear of the compartment has become a persistent problem of pollution caused by muck trucks. How to ensure that the rear of the compartment is reliably closed during operation and that the shed cover can be opened and closed smoothly without affecting loading and unloading is a technical contradiction.

[0004] In addition, the current muck trucks generally use square pipe guide rails. The upper plane of the guide rails is horizontal, and stones and other materials often fall on the top of the guide rails. The damage is serious. The tensioner for tensioning the chain is easy to get stuck on stones. In severe cases, it will hinder the running of the tackle, and even the two sides are out of sync, resulting in jamming or damage to the driving mechanism when the canopy is opened and closed.

This also affects the operating efficiency of the vehicle
