Embodiment Construction

[0019] Embodiment of the patent of the present invention: the structure device for assisting the removal of rollers is composed of a trolley that can walk on two rails, hydraulic legs 1-2 on both sides of the trolley, and rail clamps 2-2 installed on the trolley frame. When the steel rail needs to be lifted, two rail clamps 2-2 are used to clamp the steel rail, and then the hydraulic oil cylinder of the hydraulic support leg 1-2 is utilized to extend the hydraulic support leg to jack up the whole trolley and the steel rail.

[0020] The frame structure of the trolley is composed of a crossbeam 1-1 and four legs 1-3. The length of the crossbeam 1-1 is about 1.5 times the gauge, and the positions of one gauge on the crossbeam 1-1 are respectively used as four The welding points of the root legs 1-3, every two legs 1-3 are welded with the beam 1-1 in an inverted V shape, and the wheels 1-4 are installed at the lower ends of the legs 1-3. Chain 2-1 is suspended in the middle of tw...

Abstract

The invention discloses a rapid rail lifting device which comprises a trolley capable of walking on steel rails and is characterized in that hydraulic supporting legs (1-2) are installed at the two sides of the trolley, rail clamps (2-2) are installed between front and rear wheels (1-4) of the trolley through chains (2-1), and when the trolley walks on the steel rails, the two rail clamps (2-2) are located above the steel rails respectively, and the two hydraulic supporting legs (1-2) are located in the outer side of the steel rail. According to the structural characteristics of a structural device for assisting in taking out the roller, the device only needs to be pushed to the position above the ground roller to clamp the steel rail, and the ground roller pressed below the steel rail can be taken out by lifting the steel rail through the jacking hydraulic oil cylinder.

Description

technical field [0001] The invention relates to a device capable of lifting rails. Background technique [0002] During the track laying process of the Z500-T long rail laying machine, the 500-meter-long rail needs to be pushed out in advance, and then the rail fasteners should be installed. After the rail is pushed out, a roller must be installed below it every 10 meters to prevent the rail from hitting the sleeper, causing the friction of the rail to increase and push failure, and the matcha [1] to cause damage to the rail. After the rail is fully pushed out, it is necessary to take out the rollers from the bottom of the rail to make the rail fall into the groove. [0003] Because the rollers are arranged under the rails, it is necessary for the workers to pry up the rails with a crowbar to take out the rollers, which is very easy to cause danger in the process of prying the rails, and cause danger to the workers. The roller fetching trolley provided by the present inven...
