Locomotive maintenance auxiliary gantry with one-way anti-reverse ratchet mechanism

Abstract

This invention relates to a locomotive maintenance auxiliary hoist with a one-way anti-reverse ratchet mechanism. The ratchet mechanism is installed on the hoist body, along with ropes and suspension components, allowing the operator to perform lifting and lowering operations with one hand via a handle. The ratchet mechanism includes teeth and pawls, forming a one-way engagement structure that automatically locks when force is stopped to prevent rope slippage. This invention features a simple structure, convenient operation, and effectively improves the safety and efficiency of locomotive maintenance hoisting operations.

Claims

1. A locomotive maintenance auxiliary gantry with a one-way anti-reverse ratchet mechanism, comprising: a gantry body; a ratchet mechanism disposed on the gantry body; a rope passing through the ratchet mechanism; a suspension member connected to the end of the rope; and an operating handle disposed on the ratchet mechanism; characterized in that: the ratchet mechanism includes ratchet teeth and pawls, the pawls and ratchet teeth forming a one-way engagement structure, such that when the operating handle drives the ratchet mechanism to rotate, the rope is tightened, and when the force is stopped, an anti-reverse locking state is formed.

2. The locomotive maintenance auxiliary gantry as described in claim 1, wherein the rope is connected to the suspension component to form a suspension lifting structure.

3. The locomotive maintenance auxiliary gantry as described in claim 1, wherein the pawl is kept in contact with the ratchet teeth by an elastic element to maintain a one-way engagement function.

4. The locomotive maintenance auxiliary gantry as described in claim 1, wherein the ratchet mechanism is located at the crossbeam position of the gantry body.
