Abstract
Prevent lifting hook that knocks, by left cutting ferrule, right cutting ferrule and steel chain are constituteed, left cutting ferrule and right cutting ferrule have arc slot type structure respectively, left cutting ferrule arc internal surface and right cutting ferrule arc internal surface set up an elastic cover respectively, screw thread connecting rod of left cutting ferrule top fixed connection, the steel chain is in the same place with the welding of screw thread connecting rod, left cutting ferrule top and right cutting ferrule top are through pivot swing joint, left cutting ferrule bottom and right cutting ferrule bottom downwardly extending form a boss respectively, the boss of left cutting ferrule and the boss of right cutting ferrule pass through fixing bolt and connect. The utility model discloses the lifting hook has movable arc draw-in groove formula structure, and left cutting ferrule and right cutting ferrule set up the elastic cover in the arc wall that left cutting ferrule and right cutting ferrule formed can be arranged in to the insulating tube, and the phenomenon of swaing can not appear rocking in hoisting process insulating tube and lifting hook, has avoided insulating tube and lifting hook at the collision wear problem of hoist and mount in-process, has rational in infrastructure, convenient to use and safe and reliable's advantage.
Description
Technical Field
The utility model relates to a heat preservation pipe hoisting accessory, concretely relates to prevent lifting hook that knocks.
Background
The heat preservation pipe is a short name of a heat insulation pipeline, is used for conveying liquid, gas and other media, and is used in heat insulation engineering of pipelines of petroleum, chemical engineering, aerospace, military, central heating, central air conditioning, municipal administration and the like. The insulating tube needs to be hoisted by a crane in the installation process, and the insulating tube often collides with the lifting hook by friction in the hoisting process, so that the surface of the insulating pipeline is damaged, and the installation quality and the use effect of the insulating pipeline are influenced.
Disclosure of Invention
The utility model provides a prevent lifting hook that knocks to the insulating tube that solves prior art existence collides with the problem that leads to damaging with the lifting hook friction.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a prevent lifting hook that knocks, by left cutting ferrule, right cutting ferrule and steel chain are constituteed, left cutting ferrule and right cutting ferrule have arc slot type structure respectively, left cutting ferrule arc internal surface and right cutting ferrule arc internal surface set up an elastic cover respectively, screw thread connecting rod of left cutting ferrule top fixed connection, the steel chain is in the same place with the welding of screw thread connecting rod, left cutting ferrule top and right cutting ferrule top are through pivot swing joint, left cutting ferrule bottom and right cutting ferrule bottom downwardly extending form a boss respectively, the boss of left cutting ferrule and the boss of right cutting ferrule pass through fixing bolt and connect.
The steel chain is placed in a steel chain box.
The utility model discloses the lifting hook has movable arc draw-in groove formula structure, and left cutting ferrule and right cutting ferrule set up the elastic cover in the arc wall that left cutting ferrule and right cutting ferrule formed can be arranged in to the insulating tube, and the phenomenon of swaing can not appear rocking in hoisting process insulating tube and lifting hook, has avoided insulating tube and lifting hook at the collision wear problem of hoist and mount in-process, has rational in infrastructure, convenient to use and safe and reliable's advantage.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, a left clamping sleeve 1, a right clamping sleeve 2, a rotating shaft 3, a boss 4, a threaded connecting rod 5, a fixing bolt 6, an elastic cover 7, a steel chain 8 and a steel chain box 9 are arranged.
Detailed Description
As shown in the figure, a prevent lifting hook that knocks, by left cutting ferrule 1, right cutting ferrule 2 and steel chain 8 are constituteed, the steel chain is arranged in steel chain box 9, left cutting ferrule 1 has arc slot type structure respectively with right cutting ferrule 2, 1 arc internal surface of left cutting ferrule and 2 arc internal surfaces of right cutting ferrule set up an elastic cover 7 respectively, threaded connection rod 5 of 1 top fixed connection of left cutting ferrule, steel chain 8 welds together with threaded connection rod 5, 3 swing joint are passed through on left cutting ferrule top and right cutting ferrule top, left cutting ferrule bottom and right cutting ferrule bottom do not downwardly extending form a boss 4, the boss of left cutting ferrule and the boss of right cutting ferrule pass through fixing bolt 6 and connect.
The utility model discloses the lifting hook has movable arc draw-in groove formula structure, and left cutting ferrule and right cutting ferrule set up the elastic cover in the arc wall that left cutting ferrule and right cutting ferrule formed can be arranged in to the insulating tube, and the phenomenon of swaing can not appear rocking in hoisting process insulating tube and lifting hook, has avoided insulating tube and lifting hook at the collision wear problem of hoist and mount in-process, has rational in infrastructure, convenient to use and safe and reliable's advantage.
