The present invention has following advantage compared with the prior art:

1. every group of tamping tool uses the identical horizontal pendulum dynamic formula dual hydraulic rail clamping device of quadruplet.Can make railroad switch tamping tool all can press from both sides rail at common line and circuit track switch, folder rail power is big, inserts resistance effectively under the balance, has guaranteed to insert the tamping quality height under four tamping unit tamping pickaxes whiles of tamping tool smoothly.

2. every cartridge clip rail device size clamp adopts hydraulic drive, and reversal valve centralized control control is simple to operate, the operating efficiency height.

3. every cartridge clip rail device connects with hydralic hose, and adopts hydraulic quick coupler and walking frame latch to be connected with walking frame.Can be rapidly and the tamping tool walking frame decompose and take apart, make things convenient for road under the walking frame.

4. in the time of can preventing the tamping tool operation, tamping tool is lifted, guarantee that job safety is reliable because following slotting resistance is excessive.

The specific embodiment:

Implementation process of the present invention and operating principle are:

Every cover quick-speed removable horizontal swinging type dual hydraulic rail clampping device is by a big clamp oil cylinder 1 and 10, one clip pincers oil cylinders 2 of two big rail tongsrail clamps and two little rail tongsrail clamps 15 compositions.The size rail tongsrail clamp can move respectively under the effect of big or small clamp oil cylinder, and the hydraulic oil of big or small clamp oil cylinder is supplied with by two reversal valves respectively, when operation need be pressed from both sides rail with big clamp, moves the big clamp handle of reversal valve, and big clamp moves thereupon; When need are used clip clamp rail, move reversal valve clip pliers grip, little clamp moves thereupon, and big or small clamp is concurrently-acting also.

Little rail tongsrail clamp operating principle: see Fig. 5, Fig. 6.

When need clip pincers 15 folder rails, move reversal valve clip pliers grip, hydraulic oil enters clip pincers oil cylinder 2 epicoeles by oil pipe.Promote clip pincers oil cylinder piston bar 17 downwards, by clip pincers connecting rod 16, making clip pincers 15 is the center rotation with clip pincers bearing pin 13.Clip pliers hook 15-1 clamps rail 14 rail chins.When meeting rail joint, because the rail chin can't clamping, 15-2 clamps splice bar 20 fin places with the clip pliers hook.Use clip pincers 15 to get final product operation at common line or in the track switch coupling part during tamping operation.

Big clamp operating principle: see Fig. 7, Fig. 8, Fig. 9, Figure 10.

When clip pincers 15 can't press from both sides rail, move big clamp 10 handles of reversal valve, hydraulic oil enters big clamp oil cylinder 1 cavity of resorption by oil pipe, upwards spur big clamp oil cylinder piston bar 18, by big clamp connecting rod 7, making big clamp 10 is the center rotation with big clamp bearing pin 8, and big clamp 10 clamps point tongue 23, stock rail 22, the flange of rail portion that makes guard rail 24, stock rail 22, railway frog 9 each one link and lie in rail.In folder rail process, for making the folder rail accurately even, rail clamping device adopts the junction plate 11 of horizontal hunting to proofread and correct clamp, and rail clamping device is swung in the horizontal direction, guarantees two big clamps 10 accurate evenly folder rails, makes the folder rail more reliable.During tamping operation, to point tongue railway switch part, railway frog and guard rail part adopt big clamp 10 to press from both sides the rail operation.
