Airtight dual-power roller blind sealing cap

Abstract

The invention relates to an airtight dual-power roller blind sealing cap which originates from the demand for an airtight sealing cap of a construction truck compartment. The main body of the airtight dual-power roller blind sealing cap comprises a roller blind barrel, a left [-shaped guide rail and a right [-shaped guide rail, wherein the roller blind barrel is installed on the front side of the compartment, the left [-shaped guide rail and the right [-shaped guide rail are fixed to the upper ends of the two sides of the compartment respectively, and a rolling mechanism is arranged in the roller blind barrel. A roller blind body can be made of waterproof cloth or a metal roller blind or engineering plastic so as to meet special demands. One end of the roller blind body is connected with the rolling mechanism, and the other end of the roller blind body is connected with a horizontal pushing frame erected between the left [-shaped guide rail and the right [-shaped guide rail. The horizontal pushing frame is connected with a power mechanism and a motion mechanism. The compartment is sealed in the way that the horizontal pushing frame is driven by the power mechanism to drive the roller blind body to move between the left [-shaped guide rail and the right [-shaped guide rail towards the rear side of the compartment, and the sealing cap can be opened in the way that the rolling mechanism drives the roller blind body and the horizontal pushing frame to rewind between the left [-shaped guide rail and the right [-shaped guide rail. The airtight dual-power roller blind sealing cap is simple in structure, light, easy to operate, complete in airtightness, easy to maintain, safe, reliable, stable in unwinding and winding operation, free of raised dust and dust leakage in the using process, and capable of limiting the overloading behavior and the limit exceeding behavior to some extent.

Description

technical field [0001] The invention relates to a closed double power roller shutter cover. Background technique [0002] The thinking of the present invention originates from the requirement of the airtight cover of the compartment of the muck truck. With the continuous deepening of reform and opening up, construction booms have been set off all over the country. In this construction boom, various muck trucks transporting waste soil and gravel have repeatedly overloaded and caused traffic accidents, severely damaged roads over the limit, and polluted the environment with dust and leakage. Criticized. For this reason, many local governments have issued management regulations requiring that muck trucks must be equipped with a closed cover system to limit overloading and overloading, and overcome dust and leakage. At present, most of the muck dump trucks used in urban construction adopt butterfly-feather cover on both sides, which has unsatisfactory sealing performance and ...

AI Technical Summary

Problems solved by technology

At present, most of the muck dump trucks used in urban construction adopt butterfly-feather cover on both sides, which has unsatisfactory sealing performance and poor reliability, and the side panels are relatively high during installation, which does not meet the management specifications and requirements; while the existing flat Most of the rolling shutter cover systems use one power source, which requires multiple sprockets or rope pulleys. The structure is complex, prone to failure, and inconvenient to use and maintain.
