After the technical scheme is adopted, the utility model discloses beneficial effect does: the hoisting tool structure is simple in structure, safe and reliable in the hoisting process, the problems that a traditional hoisting tool is heavy, the operation is difficult and the like due to the fact that the traditional hoisting tool is influenced by the inlet and outlet guide seats of the rolling mill are effectively solved, the carrying moving distance is small, the labor intensity of operators is reduced, the efficiency is improved, and the situation that roll changing personnel are accidentally extruded or fall damaged is reduced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: the lifting device comprises a lifting belt 1, a connecting arm 2, a holding roller fixing device 3, a hinged shaft 4, a lifting ring 5, a handle 6 and a vertical section 2-1.
Detailed Description
Referring to fig. 1, the technical solution adopted by the present embodiment is: the roller hanging device comprises a hanging belt 1 used for connecting a hanging hook, a connecting arm 2 and a roller embracing fixing device 3 used for hanging a roller ring;
more specifically, the lower portion of the hoisting belt 1 is connected with two connecting arms 2, the two connecting arms 2 are connected in a cross mode, and the lower portion of each connecting arm 2 is fixedly connected with the holding roller fixing device 3 in a welding mode. The connecting arm 2 and the holding roller fixing device 3 are connected in a welding mode, so that the connecting arm 2 and the holding roller fixing device 3 can move synchronously, and the connecting stability of the connecting arm 2 and the holding roller fixing device 3 is ensured.
More specifically, a handle 6 which is convenient for an operator to pull is arranged on one side of the connecting arm 2.
More specifically, the lower end of the hoisting belt 1 is connected with the upper end of the connecting arm 2 through a hoisting ring 5. The hoisting belt 1 and the connecting arm 2 are connected by using the hoisting ring 5, so that the hoisting belt 1 and the connecting arm 2 can have certain mobility under the condition of stable connection.
More specifically, the two connecting arms 2 are hinged at the middle part through a hinge shaft 4 to form an approximate X shape. The X-shaped design can enable the two connecting arms 2 to move synchronously, and the two holding roller fixing devices 3 can be ensured to be opened and closed synchronously.
More specifically, the lower end of the connecting arm 2 is provided with a vertical section 2-1. The vertical section 2-1 is adapted to the side wall of the roll collar.
More specifically, the number of the holding roller fixing devices 3 is two, and the holding roller fixing devices 3 are U-shaped. The U shape of the roller ring is matched with the shape of the roller ring.
The utility model discloses a theory of operation: the hoisting belt 1 is connected with a lifting hook in a hanging mode, the hoisting belt 1 and the connecting arm 2 are connected through the hanging ring 5, in a free state, the opening of the two embracing roller fixing devices 3 is slightly smaller than the maximum diameter of the outer portion of the roller ring, when the hoisting tool is used, the hoisting tool is moved to the position above the roller ring, a crane is controlled to enable the hoisting tool to descend, when the embracing roller fixing devices 3 are in contact with the roller ring, the upper portion of the hoisting tool is still descended due to the lifting force exerted on the lower portion of the hoisting tool, the distance between the two connecting shafts is increased, namely the opening of the embracing roller fixing devices 3 is also increased, the embracing roller fixing devices 3 can be sleeved on the outer side of the roller ring, when the two embracing roller fixing devices 3 descend to the position of the lower end face of the roller ring along the outer wall of the roller ring, at the moment, the hoisting tool is controlled to ascend through the crane, the gap between the embracing roller fixing devices 3 is reduced, the roller ring can be hoisted tightly, the roller ring can be hoisted, and the safety is high. In the hoisting process, as long as the roll is normally hoisted, the roll holding fixing device 3 can hoist the roll collar in a clamping mode. When the roll collar is lifted in place, the crane descends to put the roll collar down, the roller embracing arm is in a slightly loose state at the moment, an outward force is applied to the handle 6, the whole hoisting tool is in a state to be opened, the hoisting tool and the roll collar can be separated as long as an operator slightly lifts the roller embracing arm, the force is small, the moving distance is small, the labor intensity of the operator is reduced, and the efficiency is improved.
The above description is only used for illustrating the technical solutions of the present invention and not for limiting the same, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
