Detailed Description

For a further understanding of the utility model, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the utility model and not limiting.

Example 1

As shown in fig. 1 and 2, the embodiment provides a hoisting sleeve for a subway long rail, which includes a sleeve body 120 with a one-way opening, wherein the sleeve body 120 is in the shape of a cuboid; the sleeve body 120 is formed by welding steel plates with the thickness of 1cm and the length of 50 cm; the side wall of the sleeve main body 120 is provided with a handle 110, the handle 110 is sleeved with a hanging ring 130, and the hanging rope 210 penetrates through the hanging ring 130; the handle 110 is disposed along the extension direction of the sleeve body 120 in an arc shape; both ends of the handle 110 are connected to both ends of the sleeve body 120 in the longitudinal direction, respectively; the sleeve main body 120 is provided with a cavity 140 for accommodating the end of the rail, the upper end of the sleeve main body 120 is provided with a lifting rope 210, the lifting rope 210 is provided with a fixing rope 220 for tightly binding one end of the rail far away from the sleeve main body 120 and the lifting rope 210, and the lifting rope 210 and the fixing rope 220 are steel wire ropes.

When the sleeve for hoisting the subway long rail in the embodiment is used for hoisting the rail, firstly, the sleeve main body 120 is sleeved at one end of the rail, then the hoisting rope 210 penetrates through the hoisting ring 130 and is bound on the hoisting ring 130, then the hoisting rope 210 is stretched to the other end of the rail, then the rail is bound on the hoisting rope 210 by the fixing rope 220 at the other end of the rail, finally, the crane is started to transport the rail to a specified place, when the rail is hoisted, one end of the rail is seated in the sleeve main body 120, and the bottom end of the sleeve main body 120 bears the weight of the rail, so that the rail is prevented from sliding in the hoisting process.
