Anti-slot-disorder hoisting machine special for railway track laying

Abstract

The invention discloses an anti-slot-disorder hoisting machine special for railway track laying. The anti-slot-disorder hoisting machine structurally includes a supporting beam frame, a control panel,a cable winding tray, walking mechanisms, telescopic hydraulic cylinders and a sleeper hoisting mechanism, the walking mechanisms are vertically installed and close to a preset track, the control panel is fixed to the upper part of the left walking mechanism through bolts, and the cable winding tray is located on the left side of the control panel. The hoisting machine special for railway track laying is provided with steel rope tighteners, when a lifting hanging bracket abuts against debris or the hanging bracket falls to the ground during the downward movement, it can be effectively ensuredthat steel wire ropes are in a tight state, and the slot-disorder phenomenon of the steel wire ropes and pulleys is avoided; and meanwhile, impurities such as sand and stone adhering to the surface of the ropes are removed in the sliding process of the steel wire ropes, abnormal noise or abrasion and jamming of the steel wire ropes in the sliding process are avoided, and the service life of a track laying machine is prolonged and the construction efficiency of track laying is improved.

Description

technical field [0001] The invention relates to the field of track machinery, in particular, it is a hoisting machine specially used for track laying of anti-chaos grooves. Background technique [0002] Rail transportation is an important part of transportation and has a huge role in promoting economic development. In order to meet the rapidly growing demand for rail transportation, China's rails, especially urban subways, are currently in a leap-forward development stage. Many cities across the country are In the vigorous construction of subway facilities, in order to reduce the work intensity in the track laying process and increase the speed of track construction, the track laying machine has been promoted. However, the current technical considerations are not perfect, and it has the following shortcomings: After the sleeper is transported to the designated position, the motor drives the steel rope to make the hanger fall to the track.

[0002] Rail transportation is an important part of transportation and has a huge role in promoting economic development. In order to meet the rapidly growing demand for rail transportation, China's rails, especially urban subways, are currently in a leap-forward development stage. Many cities across the country are In the vigorous construction of subway facilities, in order to reduce the work intensity in the track laying process and increase the speed of track construction, the track laying machine has been promoted. However, the current technical considerations are not perfect, and it has the following shortcomings: After the sleeper is transported to the designated position, the motor drives the steel rope to make the hanger fall to the track. When the hanger is supported by sundries or the hanger falls to the ground, the wire rope of the lifting mechanism is in a loose state. At this time, it is easy to cause the wire rope There is a phenomenon of chaotic grooves with the pulleys, and the chaotic grooves of the steel wire rope make the subway track laying machine unusable, which affects the progress of track construction; at the same time, because there is a lot of dust and sand in the track construction site, when the sand and stone adhere to the surface of the wire rope, it will cause the wire rope to be broken. Abnormal noise or wear occurs during the sliding process, and even causes the pulley to get stuck, shortening the service life of the equipment
