Description

Hydraulic rail-expanding joint-cutting splitting device Technical Field The utility model relates to the field of rail expansion joint cutting and splitting, in particular to a hydraulic rail expansion joint cutting and splitting device. Background The seamless track change operation in summer faces serious challenges. Especially short-distance lines after thermal expansion. The high temperature makes the steel rail generate compressive stress, and the saw blade is clamped by the stress concentration at the moment of cutting by the rail sawing machine, so that the cutting can be completed by means of a special technology. The cut steel rail is tightly balanced due to the compressive stress, is particularly stubborn in a short-distance line with obvious thermal expansion, conventionally uses a method for separating two rail-pulling devices in opposite directions, has high operation difficulty and low efficiency, and has potential safety hazards that personnel are injured by the steel rail in a spring mode. Disclosure of utility model First, the technical problem to be solved In order to solve the problems in the prior art, the utility model provides a hydraulic rail-expanding joint-cutting splitting device. (II) technical scheme In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The utility model provides a fluid pressure type rail expansion joint cutting split device, includes tripod, pneumatic cylinder, first anchor clamps and second anchor clamps, one of them side right-angle side of tripod is connected with through the mounting the pneumatic cylinder, both sides are installed respectively around the opposite side right-angle side of tripod first anchor clamps and second anchor clamps, first anchor clamps are used for pressing from both sides tight orbital rail top, the second anchor clamps are used for pressing from both sides tight orbital rail web. Preferably, the first fixture comprises 冂 type frames and fixing bolts, wherein two groups of fixing bolts are arranged on two sides of the 冂 type frames oppositely and are in threaded connection with the 冂 type frames. Preferably, the second clamp comprises clamping plates arranged in pairs, wherein one group of clamping plates are fixedly arranged on the tripod, the other group of clamping plates are detachably arranged on the tripod through bolt fixing pieces, and clamping grooves corresponding to rail tops and rail waists of the rails are formed in one sides, close to each other, of the two groups of clamping plates. Preferably, the fixing piece comprises a binding belt and a limiting block arranged at the top of the hydraulic cylinder, and the limiting block is fixedly connected with the tripod. Preferably, the tripod is made of one of steel, copper alloy or aluminum. Preferably, the tripod adopts an isosceles right triangle structure. (III) beneficial effects The rail puller has the beneficial effects that by adopting the technical scheme, the rail puller is connected with the rail top of the rail through the first clamp, then connected with the rail web of the rail through the second clamp, and matched with the hydraulic cylinder, the strong pushing force of the hydraulic cylinder is utilized to easily counter the thermal expansion pressure of the rail, so that the rail can be rapidly separated, and compared with the defect that the conventional rail puller is easy to cause the out-of-control of the rail, the rail puller accurately controls the trend of the rail, effectively avoids the swing risk, and greatly improves the operation safety.
