Please refer to fig. 1 to 10. In a first aspect, the present embodiment provides an anti-skid fixture for fixing a rail in a long rail transport vehicle, comprising a first fixture 1 and a second fixture 2 connected by a detachable connector 3, wherein the first fixture 1 is clamped to a first rail 4 to be unloaded to generate a friction force for limiting the sliding of the first rail 4; the second jaw 2 is clamped to the second rail 5 in a locked condition to generate a frictional force that limits movement of the first jaw 1 and the first rail 4.

The detachable connecting piece 3 can be specifically a group of lantern rings, each lantern ring comprises a first lantern ring which can be sleeved with a first fixture and a second lantern ring which is sleeved with a second fixture, when the detachable connecting piece is installed and used, the first fixture is sleeved in the first lantern ring and locks the first lantern ring, the second fixture is sleeved in the second lantern ring and locks the second lantern ring, so that the first fixture and the second fixture are connected together, and when the detachable connecting piece is detached, the first lantern ring and the second lantern ring are taken down; or, the detachable connecting piece 3 may also be a bolt, holes are formed in the first fixture 1 and the second fixture 2, and the bolt passes through the two holes and then is connected with the nut, so that the first fixture 1 and the second fixture 2 are connected together, and when the detachable connecting piece is detached, the nut is loosened. The first fixture 1 can be specifically connected with the first steel rail 4 through a clamping groove, the rail top of the first steel rail 4 is clamped in the clamping groove, and different clamping forces are provided to clamp the first steel rail 4 by changing the size of the clamping groove; or, two opposite clamping blocks may be disposed on the first fixture 1, each clamping block is connected to one side of the first rail 4, and the first rail 4 is clamped by applying pressure to the two clamping blocks. In this embodiment, the second fixture 2 may also adopt a similar implementation structure to the first fixture 1, which is not described again in this embodiment.

In addition, the first fixture 1 can meet the use requirements of different gradients by setting preset values of different clamping forces, for example, 10% may be used as a critical point, between 0% and 10%, the clamping force of the first fixture 1 may be a first clamping force, between 10% and 20%, the clamping force of the first fixture 1 may be a second clamping force, and when a constructor unloads a steel rail, the clamping force of the first fixture 1 may be set to a preset value designed in advance according to the current gradient.

It should be noted that the steel rails are laid on the bearing surface of the long steel rail transport vehicle in the transport process, and the adjacent steel rails are placed in parallel, so that constructors can unload the steel rails from two sides to the middle when unloading the steel rails. The rail to be unloaded is considered as the first rail 4 in this embodiment, and the rail adjacent to the first rail 4 is in a locked state in this unloading, and is considered as the second rail 5. The first fixture 1 and the second fixture 2 should be spaced apart perpendicular to the extension direction of the rail when coupled by the detachable coupling 3. Of course, the first rail 4 and the second rail 5 may be two non-adjacent rails in the present embodiment, as long as it is satisfied that the first rail 4 in unloading is the rail to be unloaded and the second rail 5 is the rail to be kept locked.

Specifically, the working principle of the anti-slip fixture provided by this embodiment is as follows:

firstly, the second fixture 2 is clamped on the second steel rail 5, the position of the second fixture 2 is kept to be fixed on the second steel rail 5 all the time, the first fixture 1 is clamped on the first steel rail 4, the first fixture 1 is connected with the second fixture 2 through the detachable connecting piece 3, the corresponding first fixture 1 is fixed relative to the second steel rail 5 through the detachable connecting piece 3 and the second fixture 2, and therefore the whole anti-sliding fixture is always in a fixed state relative to the long steel rail transport vehicle in the primary unloading process. During unloading, a constructor firstly clamps the first fixture 1 on the outermost steel rail, namely the first steel rail 4; the second fixture 2 is clamped to the rail adjacent to the first rail 1, i.e. the second rail 5. With first fixture 1 and second fixture 2 through dismantling the first rail 4 of unblock after connecting of connecting piece 3, first rail 4 receives the restriction of the frictional force of first fixture 1 and can't slide, avoids first rail 4 to slide suddenly or the drunkenness causes the incident, and constructor accomplishes the uninstallation through dragging first rail 4 and uninstalling it to subaerial. And after unloading, the detachable connecting piece 3 is taken down, the first fixture 1 and the second fixture 2 are loosened, and the next unloading is prepared.

The anti-skid fixture provided by the embodiment is clamped on the second steel rail 5 through the second fixture 2, the second steel rail 5 keeps a locking state when being unloaded, so that the second fixture 5 is fixedly arranged relative to the long steel rail transport vehicle, the first fixture 1 and the second fixture 2 are connected together through the detachable connecting piece 3, the first fixture 1 is also fixedly arranged relative to the long steel rail transport vehicle, and the anti-skid fixture provided by the embodiment is guaranteed to be always fixed relative to the long steel rail transport vehicle when the steel rails are unloaded.
