The invention discloses an external built-in type tarpaulin sealing
system with a cover. The
system comprises a dump
truck carriage, a steel
wire rope, a chain, a tarpaulin
assembly, a rear roller
assembly, a front corner
assembly, a tarpaulin rod set assembly, a motor assembly, external built-in guide rail assemblies and
pulley block assemblies, wherein one external built-in guide rail assembly is mounted at each of the left side and the right side of the dump
truck carriage; each
pulley block assembly is connected into the corresponding external built-in guide rail assembly in a rolling manner; one end of the chain is fixed to the dump
truck carriage, and the chain bypasses the motor assembly to be fixed to the
pulley block at the rightmost side; the left and right pulley block assemblies are correspondingly fixedly connected to the left end and the right end of the tarpaulin rod set assembly and are integrally connected through the steel
wire rope in a penetrating manner; the tarpaulin rod set assembly is wrapped with the tarpaulin assembly; the motor assembly is in transmission connection with the chain to drive the tarpaulin rod set assembly and the tarpaulin assembly to move forwards and backwards, so as to achieve the function of opening and sealing a tarpaulin of the carriage. The
system can be widely applied to
urban waste oil dump trucks, and enables completely-sealed transportation of a vehicle, and thus the urban
pollution can be reduced.
