Side-tipping single-sleeper pulling and replacing device

Abstract

The invention provides a side-tipping single-sleeper pulling and replacing device, which comprises a trolley frame, wherein the trolley frame is arranged above a trolley fixing mechanism, at least two trolley steel wheels are arranged under the trolley frame, at least one group of windlass and pulley mechanism is arranged under the trolley frame, a hydraulic device, an oil tank, motive power machinery, an oil cylinder and a rail sleeper clamp are arranged above the trolley frame, the oil tank provides oil materials for the motive power machinery, the oil cylinder is connected with the rail sleeper clamp and provides motive power for the rail sleeper clamp, and a rail spike sensing device is arranged under the trolley frame. The side-tipping single-sleeper pulling and replacing device has the advantages that the damage to the positioning dimension of steel rails and road beds can be avoided, the price is much lower than that of the existing sleeper replacing trolley, the side-tipping single-sleeper pulling and replacing device is also applicable to the replacement of sporadically damaged sleepers, the work intensity of workers is reduced, the service life is long, the maintenance is convenient, more precious time is won for the railway maintenance, and great significance is realized on the independent innovation of road maintenance machinery and the internationalization of domestic road maintenance machinery.

Description

technical field [0001] The invention relates to a railway pillow changing device, which belongs to the technical field of railway maintenance machinery. Background technique [0002] The railway pillow changing device is one of the main working devices in the mechanized maintenance of railway lines. At present, pillow replacement in foreign countries is mainly used as an auxiliary process of rail replacement. The premise is to destroy the positioning dimensions of the original ballast bed and rails, and it takes a long time to "skylight". In China, pillow replacement is mainly done manually. There are mainly two operation methods mentioned in academic and other patents: remove the spikes, dig trenches in the overall section, the workload is large, time-consuming, the size of the track rail is larger than 100mm, and the original positioning requirements of the rail are destroyed. These factors cannot It meets the requirements of various road bureaus, so it is not used in the...

Problems solved by technology

In addition, there are many bottlenecks in manual pillow replacement, mainly including: (1) When the temperature is too high, the physical strength of the operator is too much; (2) When the temperature is too low, the operator cannot perform manual pillow replacement operations; (3) Oxygen is thin in high altitude areas It affects the normal operation of operators; (4) The replacement of sleepers in the tunnel is limited, and the operation efficiency is low; (5) The replacement of sleepers is very difficult: the construction personnel on site are currently born in the 70s, and the workers born in the 80s and 90s cannot bear it. Due to the intensity of work, almost no one is engaged in manual pillow replacement after 10 years. This kind of "embarrassment" exists at the same time abroad.
