Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: a hoisting tool capable of realizing air overturning of an escalator truss comprises a hook 1, wherein a rotating ring 3 is arranged on the inner side of the top of the hook 1, a transmission shaft 4 penetrates through the inner side of the rotating ring 3, a U-shaped ring 8 with a U-shaped structure is arranged outside the rotating ring 3, the rotating ring 3 is positioned on the inner side of the bottom of the U-shaped ring 8, two ends of the U-shaped ring 8 are in a circular ring shape and are sleeved on two ends of the transmission shaft 4, a limiting column 9 is fixed on the inner side of the top of the hook 1, the limiting column 9 penetrates into the rotating ring 3, a limiting bulge 2 with an arc-shaped structure is fixed on the side edge of the limiting column 9, a limiting groove for inserting the limiting bulge 2 is formed in the inner wall of the rotating ring 3, when the truss is hoisted, the truss can be overturned in the air according to actual operation requirements, various installation requirements are met, meanwhile, the operation is very convenient, the safety is, the inner wall of the rotary ring 3 is uneven, and the transmission shaft 4 can roll on the inner side of the outer wheel 5.
In this embodiment, preferably, couple 1's cross section is "J" type structure, and couple 1's surface side is provided with the switch, and the inside surface is provided with anticreep arch 10, through anticreep arch 10's setting, can be in upset and normal hoist and mount, spacing to the escalator truss, prevent to drop.
In this embodiment, preferably, a connection hanging ring 7 is arranged on the top of the U-shaped ring 8, a steel cable 6 is sleeved on the inner side of the connection hanging ring 7, the steel cable 6 is inserted into the inner side of the U-shaped ring 8, a rotatable barrel is arranged on the inner side of the top of the connection hanging ring 7, and the top of the steel cable 6 is sleeved on the barrel.
In this embodiment, it is preferable that the diameter of the steel rope 6 is ten cm to ensure the stability of hoisting, and the steel rope 6 is formed by twisting a plurality of steel wires.
The working principle and the using process of the invention are as follows: when the invention is used, firstly, a switch on the outer side of a hook 1 is pressed to enable an anti-falling bulge 10 to move towards the inner side of the hook 1, then the hook 1 is clamped on an escalator truss to be hoisted, then the pressure of the switch is released, the top of the truss is limited by the anti-falling bulge 10 to avoid falling off, then a steel rope 6 is driven by a limiting bulge 2, the steel rope 6 drives a U-shaped ring 8, the U-shaped ring 8 hoists the hook 1 through a transmission shaft 4, when the escalator truss needs to be overturned in hoisting, the limiting bulge 2 rotates the steel rope 6, because under the gravity of the escalator truss and the hook 1, the steel rope 6 is in a tight state and is tightly attached to the inner side surface of the U-shaped ring 8, when the steel rope 6 rotates, the U-shaped ring 8 generates certain displacement under large friction force, and when the U-shaped ring 8 generates displacement, the U-shaped ring 8 drives the transmission shaft 4 to move through an outer wheel, because foreign steamer 5 is inseparable laminating form with the inner wall of transmission shaft 4 equally, the rolling motion is done with the inner wall of change 3 to transmission shaft 4 this moment, make transmission shaft 4 drive change 3 and rotate, because change 3 is spacing by spacing arch 2, consequently in change 3 rotations, spacing post 9 on the spacing arch 2 rotates, hook 1 rotates thereupon, thereby the completion is to the upset of automatic escalator truss, continue to hoist after that, when later stage needs to overturn once more, can go on once more through above-mentioned operation, after the hoist and mount is accomplished, press the switch, make the protruding 10 removal of anticreep to the inside of couple 1, afterwards take out the automatic escalator truss can.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
