Abstract

The utility model discloses a double acting steel rail vapour pressure welder belonging to an auxiliary apparatus for railway. The utility model is characterized in that four oil cylinders are symmetrically arranged on both left and right machine bases, and the oil cylinder corresponding is connected by piston rods. A bushing is arranged on the outside of the piston rods. A piston which extends into the right side of the oil cylinder is arranged on the right end of the bushing which is also provided with a clamp block for pushing and projection of a cutter. The structure that a plane positioning block is matched with an inclined plane positioning block to clamp and position the steel rail is used for a machine frame. The utility model can complete the implement of rail matching, welding, pushing and projection straightly, which is convenient for operation.

Description

Double-motive rail vapour pressure welder

The utility model belongs to the railway auxiliary equipment, relates to a kind of double-acting rail vapour pressure bonding machine.

Present railway line is progressively promoted long rail, and it is welded together that this needs to lack one by one rail.Construction of railways is very short to time requirement, and required precision is also high.Particularly after the rail welding, some protrudes the rail plane weld seam, needs with cutter it to be removed, otherwise will influence train running.This work progress is protruding pushing away.The main construction course that connects rail is to rail and pushes away protruding.Existing is to adopt wherein an one steel rail to locate with two wedge piece clampings to the rail method, and then another one steel rail aimed at it, again with two wedge piece clamping location, adopt this mode, just found docking location often accurately, and dislocation after clamping, so be difficult to find accurately rapidly the docking location of two one steel rails.In addition,, often can not wait until that weld seam cools off back clamping soon fully and removes, change other apparatus and push away protruding construction that like this, weld seam density is influenced, influences welding quality because the engineering time is short.On the other hand owing to after two one steel rails remove clamping, influenced by self gravitation, also easily mutually between distortion, be easy to that all that has been achieved is spoiled.

The purpose of this utility model is the many disadvantages that overcomes existing facility, provides a kind of rapid, accurate to rail, need not remove clamping and can push away protruding construction, double-acting rail vapour pressure bonding machine easy and simple to handle.

The utility model has left and right two supports, all is symmetrically installed with two oil cylinders on two supports; Between left and right corresponding oil cylinder, piston rod is installed, has a sleeve pipe, sleeve pipe right-hand member to extend in the oil cylinder of the right in the outside of piston rod, be connected with one at the sleeve pipe right-hand member and push away protruding piston; At the sleeve pipe left end pushing convex knife tool fixture block is arranged.A flat sided straight groove and a plane oblique groove are all arranged on left and right frame, have one to face locating piece directly in straight groove, it is the grip block on inclined-plane that one one side is arranged in oblique groove.

The utility model has the advantages that: to rail rapidly, accurately, can be to rail, weld, push away worker's process such as protruding and finish continuously, easy and simple to handle.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is a vertical view of the present utility model.

Elaborate below in conjunction with accompanying drawing.

The utility model is the front and back symmetry, two

frames

5 and 11 are arranged, on the frame 5 of left end, be set with the oil cylinder 4 of two symmetric arrangement, the oil cylinder 16 that two symmetric arrangement are also arranged on the frame of right-hand member, about link together by piston rod 9 between the oil cylinder of two correspondences, be weight reduction, piston rod 9 can be welded by several sections.Piston rod 9 left ends are connected with a piston 6, and oil cylinder 4 left ends have an oil cylinder cover 3, and a hole is arranged on the oil cylinder cover 3, have an oil to chew 2 in the hole, and oil is chewed 2 and linked to each other with return line.On piston rod 9, be set with a sleeve pipe 8, a pushing convex knife tool fixture block 7 arranged, also be welded with one at sleeve pipe 8 right-hand members and push away protruding piston rod 14, push away protruding piston 12 and be fixed on by nut 13 and push away on the protruding piston rod 14 at sleeve pipe 8 left ends.Right-hand member at oil cylinder 16 has an oil cylinder cover 17.All being processed with an end at piston rod 9 two ends communicates with oil cylinder inside, the hole 18 that the other end communicates with oil pipe line, about a pair of groove is all arranged on two supports, one of them is a straight trough, another is a skewed slot, the plane positioning piece 20 that a cuboid is arranged in straight trough, the grip block 19 that an one side is arranged in skewed slot is the inclined-plane has the flange of rail nut 21 of placing rail in two supports bottom.

During operation, be put on the flange of rail nut 21 of this machine by the welding steel rail two, two one steel rails are close to plane positioning piece 20 respectively, because the locating surface of two plane positioning pieces is positioned at same plane, so be easy to aim at, beat inclined-plane grip block 19 then, it is cooperated with plane positioning piece 20 rail is clamped.At this moment use other heater, as water welding with its interface fusing, then with oil pump to the left oil cylinder annotate pressure oil and enter oil cylinder 4 right space B, make piston rod 9 drive whole right support and be moved to the left, two one steel rails are connected as one the top fusion.At this moment owing to rail causes that to the top rail joint end place is higher than the rail plane, so oil cylinder injection pressure oil to the right enters oil cylinder 16 left part space A, promote piston 12 and drive sleeve pipe 8 by it to move right, at this moment whole frame is motionless.Oil return is got back to oil pump through oil pipe 15.Because operation the time is fixed on cutting knife on the pushing convex knife tool fixture block 7 in advance, along with driving cutters, moves just by fixture block 7 the projection excision of interface, and excision finishes, and iron block is laid, and just machine can be removed from the rail folding.
