Sand spraying pipe for locomotive sand sprayer

Abstract

The invention provides a sand spreading pipe for a locomotive sand spreader, which includes a connecting piece, a connecting hose and a sand outlet steel pipe. Sand steel pipe. The connector is a hollow tube with a trapezoidal boss at one end and a limited boss near the trapezoidal boss; an annular groove is arranged near the other end of the connector, and a card slot is provided at the end of the annular groove. The circlip is slidingly sleeved on the annular groove with a connecting sleeve, and the connecting sleeve is provided with an internal thread, one end is bent inward, and is sleeved on the annular groove, and the other end is threadedly connected with the locomotive sand spreader; the connecting piece is provided with a folding The bending part, the bending angle of the bending part is 130-140 degrees. The sand spreading pipe for the locomotive sand spreading device provided by the invention has the advantages of simple and compact structure, convenient disassembly and good waterproof effect.

Description

technical field [0001] The invention relates to a sand spreading pipe for a locomotive sand spreader, which belongs to the technical field of locomotives. Background technique [0002] The sand spreader is an important device on the locomotive. When the adhesion between the locomotive wheel and the wheel rail is low, causing the locomotive wheel to spin, the sand spreader is used to spread sand between the wheel and the wheel rail to increase the gap between the two. The frictional force can play a role in inhibiting wheel idling and ensure the normal start of the locomotive. [0003] The sanding pipe is the sanding pipe of the sanding device. In the prior art, the sanding device is usually connected to the sanding metal pipe through a sanding hose. Generally, a connecting piece and a connecting hose are used to connect the sanding device and the sanding device. On the metal pipe of the outlet, and then fixed by the clamp. There are the following problems in the sand sprea...

AI Technical Summary

Problems solved by technology

There are the following problems in the sand spreading pipe of the prior art: 1, the structure is complicated, and it is inconvenient to disassemble

The existence of the clamp not only makes the structure complicated, but also inconvenient to disassemble, time-consuming and labor-intensive; 2. The vibration of the locomotive during operation may easily cause the clamp to loosen, and the sanding pipe may not be fixed firmly, which may easily cause the sanding hose to fall off, and rain and snow may easily cause rain. Protruding in, the sand is wet, loses fluidity and blocks the sand outlet, affecting the operation of the locomotive
