Problems solved by technology

[0002] At present, the XYD-2 hydraulic tamping machine used on railways uses mechanical clamps to clamp the rails. The clamps are opened and clamped by the lifting force or downward insertion force of the lifting cylinder. The clamps can only clamp the side of the rail head. , it is impossible to realize the rail clamping of the turnout rail switch part or the frog part, and the turnout tamping operation cannot be carried out

Embodiment Construction

[0022] Implementation process and action principle of the present invention are:

[0023] Each set of fast detachable horizontal swing double hydraulic rail clamping device is composed of a large clamp cylinder 1 and two large clamp clamps 10, a small clamp cylinder 2 and two small clamp clamps 15. The large and small rail clamps can be operated separately under the action of the large and small clamp cylinders. The hydraulic oil of the large and small clamp cylinders is respectively supplied by two reversing valves. The handle, the big clamp moves accordingly; when the small clamp is needed to clamp the rail, move the small clamp handle of the reversing valve, the small clamp moves accordingly, and the large and small clamps can also move at the same time.

[0024] Action principle of the small rail clamp: see Figure 5 , Figure 6 .

[0025] When needing small clamp 15 clamp rails, move reversing valve small clamp handle, hydraulic oil enters small clamp oil cylinder 2 up...

Abstract

The detachable horizontally swinging double hydraulic rail clamper for switch tamping machine features its large and small clamp oil cylinders fixed via fixing clamping board to the support, two small clamp sleeves on small clamp shaft pins and connected to the support, two large clamps on two clamp pin shafts separately and connected to the clamp support, large clamp oil cylinder and large clamp piston rod connected to the two large clamps via the large clamp link rod, small clamp oil cylinder and small clamp piston rod connected to the two small clamps via the small clamp link rod, and the clamp support connected via swinging connecting board bolt and walking frame bolt to the walking frame of the switch tamping machine and capable of swinging horizontally. The rail clamper can clamp switch tongue switcher and rail bottom in frog to ensure the tamping operation of the tamping machine in common line and switch.

Description

Technical field: [0001] The invention relates to the technical field of railway tamping equipment, in particular to a fast detachable horizontal swing double hydraulic rail clamping device for a turnout tamping machine. Background technique: [0002] At present, the XYD-2 hydraulic tamping machine used on railways uses mechanical clamps to clamp the rails. The clamps are opened and clamped by the lifting force or downward insertion force of the lifting cylinder. The clamps can only clamp the side of the rail head. Therefore, it is impossible to realize the rail clamping of the turnout rail switch part or the frog part, and it is impossible to carry out the turnout tamping operation. Invention content: [0003] The object of the present invention is to provide a fast detachable horizontal swing double hydraulic rail clamping device for a turnout tamping machine, which can clamp rail chins, fishplate ribs, switch tip rail switches, and rails of frog parts. Balance the lower...
