Description

Leveling Roll Lifting Tool

technical field

The utility model relates to a hoisting tool, in particular to a leveling roller hoisting tool.

Background technique

The hot-rolled leveling line uses a two-roller mill. The roll diameter of the leveling roll is about 1012mm, and the weight of each roll is about 33 tons. Because at the beginning of the design, there is no special spreader designed for this type of roll. After the unit was put into normal production, with the increase of output, the use and consumption of rolls increased significantly, and the replacement frequency of each shift rose sharply. Please refer to Fig. 1, but in production and use, because there is no sling for special leveling roll 1, the operator generally adopts two wire ropes 2 to hoist when replacing leveling roll 1. In the operation of driving and lifting, due to the shaking of the driving and the structure of the roller itself, one side is high and the other is low, which causes a large safety hazard in the roller changing operation. At the same time, in order to ensure safety, make The speed of changing rolls is slow and the replacement time is long, which affects normal production.

Utility model content

In view of the above-mentioned shortcomings in the prior art, the purpose of this utility model is to provide a leveling roll hoisting tool, which can ensure smooth lifting of the leveling roll and reduce the occurrence of safety accidents.

In order to achieve the above object, the utility model adopts the following technical solutions:

The leveling roller hoisting tool includes a bottom plate, a screw rod, a counterweight and a driving part. A pair of slide rails are arranged on the bottom plate; a pair of screw rods are fixed on the bottom plate; a pair of counterweights are respectively sleeved on the corresponding screw rods. And carry out thread fit, the bottom of the counterweight is set on the corresponding slide rail; the driving part is connected with the screw rod; there is also a pair of lifting lugs on the bottom plate, and the lifting lugs are connected by pin shafts. There are side plates on both sides of the bottom plate. There are hanging feet on the board.

The driving part is a pair of handwheels, which are respectively arranged at one end of the corresponding screw mandrel and connected with the corresponding end of the screw mandrel through a clutch.

The driving part is a motor, which is arranged between the screw rods, and its output end is respectively connected with the two screw rods through gear linkage.

The number of the hanging legs is four.

In the above technical solution, the leveling roller hoisting tool of the present invention includes a bottom plate, a screw, a counterweight and a driving part, a pair of slide rails are arranged on the bottom plate; a pair of screw rods are fixed on the bottom plate; a pair of counterweights They are respectively sleeved on the corresponding screw rods and threaded, and the bottom of the counterweight is set on the corresponding slide rail; the driving parts are connected with the screw rods; there are also a pair of lifting lugs on the bottom plate, and the lifting lugs are connected by pins. Both sides of the bottom plate are provided with side panels, and the side panels are provided with hanging feet. The rotation of the screw rod can drive the balance weight to move left and right to adjust the balance of the smoothing roller during hoisting, so as to ensure the smooth hoisting of the smoothing roller and avoid safety accidents.

Detailed ways

The technical scheme of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

Please refer to Fig. 2 to Fig. 5, the leveling roller hoisting tool 10 of the present utility model includes a base plate 11, a screw mandrel 12, a counterweight 13 and a driving part, and a pair of slide rails 14 is arranged on the base plate 11; a pair of screw mandrels 12 The bearings 111 are fixed on the bottom plate 11; a pair of counterweights 13 are respectively sleeved on the corresponding screw rods 12 and threaded, and the bottom of the counterweights 13 is set on the corresponding slide rails 14; the driving part and the screw rod 12 are connected; the base plate 11 is also provided with a pair of lifting lugs 15, and the lifting lugs 15 are connected by pin shafts 151. The two sides of the base plate 11 are provided with side plates 112, and the side plates 112 are provided with hanging feet 113. As an embodiment, the driving part is a pair of handwheels 16 , which are respectively arranged at one end of the corresponding screw rod 12 and connected with one end of the corresponding screw rod 12 through a clutch 161 . As another embodiment, the driving component is a motor 17 , which is arranged between the screw rods 12 , and its output ends are respectively connected to the two screw rods 12 through gear linkages 18 . Certainly, also can install hand wheel 16 and motor 17 to drive simultaneously. In addition, the number of hanging feet 113 is four, which are respectively used to install the steel wire rope 2, and the leveling roller is hoisted by four short steel wire ropes 2. An inductive receiver 19 can also be installed on the motor 17, thereby realizing remote automatic control of the motor 17.

The working principle of the lifting tool is as follows:

First hook the main hook 3 of the crane to the pin shaft 151 of the lifting lug 15, and move the hoisting tool 10 above the leveling roller 1, then install the corresponding steel wire rope 2, fix the steel wire rope 2 and the leveling roller 1, and lift it by driving. Hoist the leveling roll 1 from the rolling mill platform, if the two ends of the hoisted leveling roll 1 are found to be high or low, then use the hand wheel 16 to manually or the motor 17 to automatically drive the screw 12 to rotate, and drive the two counterweights 13 to lift the leveling roll 1 One end of the roller moves to play the role of counterweight on this side until the leveling roller 1 maintains a horizontal balance, thereby achieving smooth hoisting.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
