Abstract

The utility model provides a rolling -mill housing roller roll changing carriage, hang and the steel cable is constituteed by frame, wheel, bracket, support frame, chain, being equipped with the wheel below the frame, being equipped with two brackets that have " U " shape groove above the frame, be fixed with one " L " shape support frame in the frame front side, the central beam who buckles backward in support frame upper portion hangs 2 chains and hangs, and the steel cable has been hung respectively on hanging the lifting hook of lower extreme to the chain, and the frame front end has the couple. The utility model discloses simple structure, it is nimble convenient to use, safe and reliable, operation labour saving and time saving can greatly shorten roll changing time, improves the operating efficiency, alleviates intensity of labour to eliminate the potential safety hazard.

Description

Roll mill roll changing carriage

Technical field

The utility model belongs to technical field of mechanical equipment, particularly relates to a kind of roll changing carriage being specifically designed to replacing roll mill.

Background technology

Roughing mill is the key equipment in hot continuous rolling production line production technology link, and breast roll is then one of most important part of roughing mill, and its effect is transport slab.The Main Function of roughing mill is cogging, namely heavy slab is rolled into sheet billet, and therefore during rolling, slab is very large to the impulsive force of breast roll, and the probability that breast roll damages also increases.The weight of breast roll itself is at about 3.5 tons, rolling-mill housing narrow space, breast roll turnover milling train needs chain to hang cooperation crane operation, by the restriction of operating condition, change breast roll operation very difficult, not only replacing construction is long, and operating efficiency is low, labour intensity is large, and there is certain potential safety hazard.

Summary of the invention

The utility model aims to provide a kind of safe and reliable, can shorten roll changing time, improves operating efficiency, the roll mill roll changing carriage reduced labor intensity.

For this reason, the solution that the utility model is taked is:

A kind of roll mill roll changing carriage, by vehicle frame, wheel, bracket, bracing frame, chain hangs and steel cable forms; Below vehicle frame, wheel is housed, above vehicle frame, is provided with two brackets with " U " shape groove, on front side of vehicle frame, be fixed with one " L " shape bracing frame, hang 2 chains in the middle part of the crossbeam that bracing frame top bends backward and hang, the suspension hook that chain hangs lower end hangs with steel cable respectively.

Described vehicle frame front end is with hook.

The beneficial effects of the utility model are:

The utility model structure is simple, and flexible and convenient to use, safe and reliable, it is time saving and energy saving to operate, and greatly can shorten roll changing time, improves operating efficiency, reduces labor intensity, and eliminate safe hidden trouble.

Accompanying drawing explanation

Fig. 1 is roll mill roll changing carriage using state schematic diagram.

In figure: wheel 1, vehicle frame 2, bracket 3, breast roll 4, steel cable 5, crossbeam 6, chain hang 7, bracing frame 8, hook 9.

Detailed description of the invention

As seen from Figure 1, the utility model roll mill roll changing carriage, mainly by wheel 1, vehicle frame 2, bracket 3, steel cable 5, chain hang 7 and bracing frame 8 formed.Vehicle frame 2 is equipped with 4 wheels 1 below, and wheel 1 is rail wheel; Vehicle frame 2 is provided with two brackets 3 with " U " shape groove above, be fixed with one " L " shape bracing frame 8 in the front side of vehicle frame 2, be hung with 2 chains in the middle part of the crossbeam 6 that bracing frame 8 top bends backward and hang 7, chain hangs 7 lower ends with suspension hook, suspension hook hangs with steel cable 5 respectively, for bundle around breast roll 4.For the ease of being connected with replacing working roll car, be also provided with hook 9 in the front end of vehicle frame 2.

During dismounting breast roll 4, this roll changing carriage is advanced in rolling-mill housing, after putting breast roll 4 on the spot with twice steel cable 5, hang 7 by chain and breast roll 4 sling and is placed on bracket 3, then with changing working roll car, this roll changing carriage is pulled out frame.During installation frame roller 4, first breast roll 4 being placed on bracket 3, then with changing working roll car, this roll changing carriage being sent in frame, by chain hang 7 and steel cable 5 breast roll 4 is sling, can smoothly breast roll 4 be in place.
