The spacing device of the present invention is described below in conjunction with fig. 1 to 3.

As shown in fig. 1 to 3, the limiting device provided by the embodiment of the utility model includes a limiting block 1 and a limiting bracket 3, specifically, the limiting block 1 is used for being connected with a traction rope 2 of a winch, the limiting bracket 3 is used for being arranged on a frame 4 of the winch, and a limiting gap is arranged on the limiting bracket 3, and the limiting gap can be passed by the traction rope 2 and can limit the passage of the limiting block 1.

A frame 4 of the winch is provided with a limiting support 3, and the end part of a traction rope 2 of the winch is connected with a limiting block 1 and a hook 12 after passing through a limiting gap on the limiting support 3.

At the in-process of hoist roll-up traction rope 2, the tip of traction rope 2 is close to spacing support 3 gradually, and when stopper 1 removed to spacing support 3 along with traction rope 2, interact between spacing support 3 and the stopper 1 can hinder passing through of stopper 1 to the restriction is to the receipts of crossing of traction rope 2, avoids traction rope 2's tip to be rolled up to reel 13. The problem that the traction rope 2 is completely wound on the winding drum 13 due to over-winding operation of the winch in the prior art is effectively solved.

In the embodiment of the utility model, the limiting block 1 is arranged into a disc-shaped structure, and particularly, the limiting block 1 can be arranged into a disc shape, so that the diameter of the limiting block 1 is larger than the size of the limiting gap, the traction rope 2 penetrates through the limiting block 1 along the thickness direction of the disc-shaped structure, and when the winch winds up the traction rope 2, the limiting block 1 can be ensured to be abutted against the side wall of the limiting gap.

The limiting gap may be a limiting hole or a limiting groove formed in the limiting bracket 3.

In a specific embodiment, the limiting gap may be provided in the form of a limiting hole, the limiting gap is rectangular, and the length direction of the rectangle is consistent with the axial direction of the winding drum 13 of the winding machine. The diameter of the limiting block 1 is at least larger than the width of the limiting gap, so that the limiting gap can limit the limiting block 1 to pass through.

The limiting block 1 is provided with a mounting hole 5 for connecting with the traction rope 2. The winch is generally connected to the heavy object by means of the hook 12 when it is in operation. After the traction rope 2 is passed through the mounting hole 5, the traction rope 2 is passed through the connecting hole 9 of the hook 12, and then the traction rope 2 is bent and the end of the traction rope 2 is bound and fastened by a binding wire or a binding piece 14.

The size of the mounting hole 5 is not too large, and needs to be smaller than the size of the hook 12 to prevent the stopper 1 from falling off from the hook 12 at the end of the traction rope 2 while ensuring that the traction rope 2 can pass through.

In the embodiment of the utility model, the limiting block 1 is arranged into two parts which are detachably connected, and refer to fig. 2. Particularly, stopper 1 includes two limiting plates 6, is provided with open slot 7 at the link of limiting plate 6, and the connection can be dismantled to the link of two limiting plates 6, and when the link of two limiting plates 6 was linked together, open slot 7 of two limiting plates 6 was linked together and can be formed above-mentioned mounting hole 5.

So set up, can be connected stopper 1 and traction rope 2 again after traction rope 2 is connected with couple 12. To the operation machinery that has the hoist engine among the prior art, need not to dismantle spare parts such as couple 12, can with stopper 1 direct mount on the haulage rope 2 of hoist engine, simple to operate, labour saving and time saving, strong adaptability.

Be provided with location structure between two limiting plates 6, when installing stopper 1 on traction rope 2, location structure can fix a position the relative position between two limiting plates 6, is convenient for connect.
