Locking clamping track instrument

Abstract

The invention discloses a locking clamping track instrument, which comprises a base with an inverted U-shaped cross section, an arc-shaped panel, a handle locking seat, a handle, a handle rotating shaft, a contact surface, a handle rotating shaft seat, a handle tension spring, at least one pair of gripper arms and torsional springs, wherein the base is used for sleeving a rail; the arc-shaped panel is fixedly arranged on the base; the cambered surface of the arc-shaped panel is matched with a wheel; the handle locking seat is fixedly arranged on the base; the handle locking seat is provided with a locking slot; the front end of the handle is provided with locking clamping blocks; the locking clamping blocks are correspondingly arranged in the locking slot under the state that the handle is locked; the handle is also provided with the handle rotating shaft; the tail of the handle is provided with the contact surface; the contact surface downwards presses when the handle rotates around the handle rotating shaft; the handle rotating shaft seat is provided with handle rotating shaft holes; the handle rotating shaft can linearly slide in the handle rotating shaft holes along the inner outlines of the handle rotating shaft holes; the handle tension spring is used for applying a force in the length direction of the base to the handle; the at least one pair of gripper arms is arranged on two sides of the width direction of the base; the torsional springs correspondingly sleeve the gripper arms.

Description

technical field [0001] The invention relates to a rail clamping device, in particular to a rail clamping device used for an overhead crane. Background technique [0002] Generally, there are more than two bridge cranes in the same span workshop. Generally, there are two situations in which the rail clamps installed on the rails need to be used during the overhaul of the overhead crane. One situation is: when one of the bridge cranes is shut down for maintenance, in order to avoid the malfunction of the bridge crane being overhauled, a rail clamp needs to be installed between the wheels and the rails to prevent the bridge crane from moving; the other The situation is: the rail clamp is installed near the bridge crane under maintenance, so as to prevent the adjacent running bridge cranes from moving in the direction of the bridge crane under maintenance and colliding with each other, thereby preventing the bridge on the track. The role of the sliding crane. If no measures a...

Problems solved by technology

However, if figure 2 As shown, after the rail clip 10 is directly installed on the track 4, it can move and fall off on the rail 4 because there is no locking function. Especially in the track maintenance process, the maintenance personnel are easy to knock over the rail clip and In addition, when the rail clamp prevents the bridge crane from moving, its wheel 5 is stuck on the flat steel plate 3. The contact area between the flat steel plate 3 of the rail clamp and the wheel body on the arc surface is small, and the rail clamp 10 is easy to slip and deformation

In addition, since the rails of the bridge crane are all at high altitude, the rail clamps falling from the rails are likely to cause personal injury and death of ground workers
