Abstract

The utility model discloses a suspending tool for a skin pass roll, which comprises a bottom board, lead screws, matching blocks and a drive component, wherein a pair of sliding rails are arranged on the bottom board, a pair of lead screws are fixedly arranged on the bottom board, a pair of matching blocks are respectively sleeved on the corresponding lead screws for screw thread matching, the bottoms of the matching blocks are arranged on the corresponding sliding rails, the drive component is connected with the lead screws, a pair of lifting lugs are further arranged on the bottom board, and are connected through a pin shaft, lateral boards are arranged on two sides of the bottom board, and hitching legs are arranged on the lateral boards. The matching blocks can be driven to move left and right to adjust the balance of the skin pass roll during the suspending through rotating the lead screws, so that stable suspension of the skin pass roll is ensured, and safety accidents are avoided.

Description

Smooth roller lifting device

Technical field

The utility model relates to lifting device, more particularly, relates to a kind of smooth roller lifting device.

Background technology

What the hot-rolled leveling line used is duo mill, and the roller footpath of its smooth roller is about 1012mm, and the weight of each root roll is about 33 tons.Owing at the beginning of design, do not have Roller Design special hanger at this type.After unit dropped into ordinary production, along with the lifting of output, the use of roll consumes obviously to be increased, and the replacing frequency straight line of per tour rises.See also shown in Figure 1ly, but in produce using, owing to there is not the suspender of special-purpose smooth roller 1, operating personal changes that smooth roller 1 is general to adopt two steel ropes 2 to lift.In the driving lifting job; owing to rocking and the reasons such as self structure of this roller of driving; high on one side, the low phenomenon in one side takes place through regular meeting; cause the bigger potential safety hazard of existence in the roll change operation; simultaneously, in order to ensure safety, make that roll change speed is slow; the replacing time is long, has influence on normal production.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of smooth roller lifting device, and this lifting device can guarantee steadily to lift smooth roller, reduces the generation of safety misadventure.

For achieving the above object, the utility model adopts following technical scheme:

This smooth roller lifting device comprises base plate, screw mandrel, clump weight and drive element, and base plate is provided with a pair of slide rail; A pair of screw mandrel is fixedly arranged on the base plate; A pair of clump weight is sheathed on the corresponding screw mandrel respectively and carries out screw thread fit, and the clump weight bottom is located on the corresponding slide rail; Drive element links to each other with screw mandrel; Also be provided with a pair of hanger on the base plate, link to each other by bearing pin between hanger, the base plate both sides are provided with side plate, and side plate is provided with hanging feet.

Described drive element is a pair of handwheel, is located at corresponding screw mandrel one end respectively, and links to each other with corresponding screw mandrel one end by power-transfer clutch.

Described drive element is a motor, is located between the screw mandrel, and its mouth links to each other with two screw mandrels respectively by the gear interlock.

The quantity of described hanging feet is four.

In technique scheme, smooth roller lifting device of the present utility model comprises base plate, screw mandrel, clump weight and drive element, and base plate is provided with a pair of slide rail; A pair of screw mandrel is fixedly arranged on the base plate; A pair of clump weight is sheathed on the corresponding screw mandrel respectively and carries out screw thread fit, and the clump weight bottom is located on the corresponding slide rail; Drive element links to each other with screw mandrel; Also be provided with a pair of hanger on the base plate, link to each other by bearing pin between hanger, the base plate both sides are provided with side plate, and side plate is provided with hanging feet.Can drive the clump weight sway by screw mandrel rotation, adjusting the balance of smooth roller in the lifting, thereby guarantee the steady lifting of smooth roller, avoid taking place safety misadventure.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 2～shown in Figure 5, smooth roller lifting device 10 of the present utility model comprises base plate 11, screw mandrel 12, clump weight 13 and drive element, and base plate 11 is provided with a pair of slide rail 14; A pair of screw mandrel 12 is fixedly arranged on the base plate 11 by bearing 111; A pair of clump weight 13 is sheathed on the corresponding screw mandrel 12 respectively and carries out screw thread fit, and clump weight 13 bottoms are located on the corresponding slide rail 14; Drive element links to each other with screw mandrel 12; Also be provided with a pair of hanger 15 on the base plate 11,15 of hangers are continuous by bearing pin 151, and base plate 11 both sides are provided with side plate 112, and side plate 112 is provided with hanging feet 113.As an embodiment, described drive element is a pair of handwheel 16, is located at corresponding screw mandrel 12 1 ends respectively, and links to each other with corresponding screw mandrel 12 1 ends by power-transfer clutch 161.As another embodiment, described drive element is a motor 17, is located between the screw mandrel 12, and its mouth links to each other with two screw mandrels 12 respectively by gear moving part 18.Certainly, also handwheel 16 can be installed simultaneously and motor 17 drives.In addition, the quantity of described hanging feet 113 is four, is respectively applied for steel rope 2 is installed, and lifts by 2 pairs of smooth rollers of four straps.On motor 17, also inducing receiver 19 can be installed, thereby realize remote auto control motor 17.

The principle of work of this lifting device is as follows:

Earlier the main hook 3 of driving is hooked the bearing pin 151 of hanger 15, and lifting device 10 moved to smooth roller 1 top, corresponding steel rope 2 is installed then, and it is steel rope 2 and smooth roller 1 is fixing, by the driving lifting, smooth roller 1 is hung out from the milling train platform, if find smooth roller 1 two ends of lifting height is arranged, then by handwheel 16 manual or motor 17 driving screw mandrels 12 rotations automatically, driving the end that two clump weights 13 raise toward smooth rollers 1 moves, play the counterweight effect of this side, keep horizontal equilibrium, thereby realize steadily lifting until smooth roller 1.
