Rain hat apparatus for heavy construction equipment

Abstract

A rain hat device for heavy construction equipment which is installed adjacent to an exhaust gas discharging port of a distal end portion of an exhaust pipe to prevent inflow of rainwater therein is disclosed. The rain hat device includes a mounting bracket having a fixing shaft which is installed on an upper portion of the exhaust gas discharging port of the distal end portion of the exhaust pipe, the mounting bracket fixing the fixing shaft at a position higher than the distal end portion of the exhaust pipe; and a swing cover having a cover support portion connected to the fixing shaft and extending between the fixing shaft and the exhaust gas discharging port, and a weight portion, in which the cover support portion is rotated around the fixing shaft by pressure of exhaust gas discharged from the distal end portion. The swing cover is installed on an upper portion of the exhaust gas discharging port in a floating state by the cover support portion so that a weight center is positioned between the fixing shaft and the exhaust gas discharging port when the discharging pressure of the exhaust gas is generated.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2009-0011047 filed with the Korean Intellectual Property Office on February 11, 2009, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a rain cover device for heavy construction equipment, and more particularly to such a rain cover device for heavy construction equipment in which a swivel cover is mounted on the distal end portion of the exhaust pipe in a state of leaving and floating so as to prevent rain Into the exhaust pipe distal end portion, and wherein the rotating cap is not in contact with the exhaust pipe distal end portion to prevent noise due to contact and collision when the engine is stopped or exhaust gas is not emitted.

AI Technical Summary

Problems solved by technology

However, since the pressure of the exhaust gas is lower than the torque M when the engine is idling or stopped, the inner surface 21 of the cap 23 contacts the distal end portion 106 of the exhaust pipe 105 to generate noise

[0019] There is an additional problem of drivers or workers suffering from noise and thus reduced productivity

[0020] Also, in the case of a large-sized excavator, since the distal end portion 106 of the exhaust pipe 105 is extended, the workload is significantly increased, such as for transportation purposes, requiring a troublesome disassembly / assembly process
