[0002] Large gantry cranes and other machinery are moved by guide rails. When in use, they need to be stopped and fixed on the track in order to work. Because the equipment is too large, it is easily disturbed by strong winds and even blown down. Therefore, a track clamp is needed to clamp the gantry crane and the guide rail together to ensure overall stability.

[0003] Existing gantry crane hydraulic rail clamps are generally electrically or hydraulically driven, and can quickly clamp the gantry crane in a short period of time, thereby locking the gantry crane to prevent further movement, thereby ensuring safety and stability during construction and use.

[0026] According to this specific embodiment, the rail clamping mechanism 104 is fixedly connected to the rail clamping box 102, and the rail clamping box 102 is slidably connected to the track 101.

The currently arranged lifting cylinder 105 cooperates with the lifting gas rod 106 to quickly clamp and lift the height of the rail clamping mechanism 104, so that when the rail clamping box 102 needs to be moved, the time required for adjusting the clamping posture can be adjusted. This design solves the problem that when the rail clamp is not started, the rail clamping unit 113 inside the rail clamp is clamped and fixed to the track 101, and manual lifting and derailing is required to move the gantry crane, which is complicated to operate and inconvenient to use.

[0027] The rail clamping mechanism 104 is located inside the rail clamping box 102, the rail clamping box 102 is located above the rail 101, one end of the two lifting screw rods 107 are located at the lower end of the lifting gas rod 106, and the other ends of the two lifting screw rods 107 are located on both sides of the rail clamping mechanism 104, the lifting cylinder 105 is located above the rail clamping box 102, and the two clamping rods are driven by the oil cylinder 120 to clamp the I-shaped plate 101. 8 After clamping, in order to quickly detach the clamping rod from the I-plate 108 and facilitate the normal movement of the box 110, the lifting air rod 106 is driven by the lifting cylinder 105, which drives the two lifting screw rods 107 to adjust the height of the clamping rod and the hydraulic unit 115.
