the clamping groove is composed of two clamping groove vertical plates and a back plate, the clamping groove vertical plates are in a right trapezoid shape, and the inclined edges of the two clamping groove vertical plates are arranged in front of and behind the straight edges of the two clamping groove vertical plates; the back plate left end and the right-hand member respectively with the rear end welded fastening of two draw-in groove risers, the welding of back plate lower extreme is on the bottom plate at rectangle slot hole rear, the distance between two draw-in groove risers is the same with the width of rectangle slot hole, two draw-in groove risers weld on the bottom plate, wherein the front end of two draw-in groove risers is located the left end and the right-hand member at rectangle slot hole rear portion, the front end at two draw-in groove risers is fixed respectively at the both ends of baffle, the baffle be located the top at rectangle slot hole rear.

The cutting knife is installed in the rectangular long hole behind the baffle, and the cutting knife stretches out 20mm downwards from the rectangular long hole, installs the wedge wood in the draw-in groove behind the cutting knife, and the wedge wood rear end is hugged closely on the backplate of draw-in groove, and the left end and the right-hand member of wedge wood are hugged closely respectively on two draw-in groove risers, and the front end top of wedge wood is on the cutting knife, has just so realized spacing to the cutting knife. If the foam board requires different cutting depths, the length of the cutting knife extending out of the base plate can be adjusted, and then different wedge woods are used for fixing the cutting knife.

The utility model has the advantages that: during construction, the bottom plate of the device is arranged on ballastless track base plates on two sides of the end portion of the expansion joint, the cutting knife is aligned with the expansion joint, one hand push handle is used, one hand pull rod is used for advancing forwards along the expansion joint, the foam board in the expansion joint is cut through the protruding cutting knife, and the guide reinforcing steel bar positioned at the rear of the cutting knife can ensure that the moving direction of the device is consistent with the expansion joint in the expansion joint.

The device can rapidly cut off the foam board, the cutting of a single expansion joint can be completed in only 3 minutes, the cut is smooth and attractive, the depth can be effectively controlled, and the working efficiency is greatly improved. The device does not need electricity and water, and does not consume resources.
