Swing type spike spinning extractor

Abstract

The invention relates to a swing type spike spinning extractor, and belongs to the field of railway construction. A pull-out clamping groove is included. A groove body of the pull-out clamping grooveis narrow in the lower portion and wide in the upper portion and is in a stepped groove shape, the upper portion of the groove body of the pull-out clamping groove is matched with a spike cap of the spike, the lower portion of the groove body is matched with a spike body of the spike, the width of the lower portion of the groove body is consistent with the width of the spike body, and a thicknessof the lower portion of the groove body is smaller than a distance between a nail cap and a sleeper. The upper end of the groove body of the pull-out clamping groove is hinged to a lever through a pinshaft, after the pull-out clamping groove is matched with the spike, the axis of the pin shaft is perpendicular to and intersects with the center line of the spike, and a pedal is fixed to the tail end of the lever. The spike is pulled out by means of self-weight and swing of a human body, the operation process is very safe and labor-saving, a pillow surface is not damaged, electric power supplyis not needed, the use cost is extremely low, and a construction period is greatly shortened.

Description

technical field [0001] The invention relates to a swing-type road stud spin puller, which belongs to the field of railway construction. Background technique [0002] Sleepers are also called oiled sleepers, which must be made of tough and elastic wood. Due to the materials used, the elasticity, strength and durability of wooden sleepers are not uniform enough, which will increase the dynamic effect of the wheel and rail, and a large amount of high-quality wood must be used. The service life of wooden sleepers is short, and there are many reasons for its failure, mainly decay, mechanical wear and cracking. Because wooden sleepers are perishable, they must undergo anti-corrosion treatment before going on the road. Due to the high elasticity of the wooden sleeper, its deformation is relatively large when the train passes by, and the rail has a certain impact on the spikes, and the spikes are easy to loosen over time. After loosening, rainwater easily penetrates between the s...

AI Technical Summary

Problems solved by technology

If you use an ordinary crowbar, the resistance arm of the crowbar is relatively large, and it is difficult to pry it up, and the cap of the spike is narrow, which is easy to slip off, causing danger and damage to the sleeper; if you use a hydraulic nail puller, the cost High, heavy, not easy to carry, slow speed, the clip of the hydraulic nail puller is not easy to snap into the nail body, and the mobile power supply is troublesome, and it is not convenient for construction in rainy and snowy weather
