Smoothly enter in sand pipe under the Action of Wind pressure of pressure airduct, and moved along sand pipe, be directionally sprayed at corresponding position
Put.
The stucco rubber hose of sander is straight tube in the market, with sandbox part Hard link, is run in vehicle
When sebific duct bend, stretch, stress, the attachment means at straight tube both ends are produced with very strong drag force, end can be made when serious
Joint's falling off, influence the traffic safety performance of locomotive.And stucco straight tube becomes from case of bending to straight condition in running
Axial distortion power can be produced during change, increases the stress of pipe shaft, and the connection to both ends adversely affects, so as to increase locomotive fortune
Row failure.
The content of the invention
The present invention is for the problems of the prior art and connection angle of sandbox and sand pipe, direction and stress ring
Border, there is provided it is a kind of that there is insulation, special-shaped stucco rubber hose wear-resisting, low temperature flexibility is good, eliminate sebific duct during use
Axial twist power, alleviate two end connector stress, specification installation operation, higher requirement met, suitable for big
Deformation, applying working condition are harsh, the sander of EMU under the conditions of vibration acutely etc..
The purpose of the present invention is achieved through the following technical solutions：
