Abstract
The invention relates to the technical field of cold rolled production auxiliary equipment, and provides a quick dismantling and replacing device for bearing pedestals of a working roll. The quick dismantling and replacing device comprises a roll replacing rack, two hydraulic trolleys, four tracks arranged in parallel, and a roll storage rack, wherein each hydraulic trolley is arranged on two tracks, and the roll replacing rack and the roll storage rack are fixedly arranged in the middle of the tracks. The quick dismantling and replacing device has the advantages and the positive effects as follows: due to adoption of the technical scheme, eight working rolls can be replaced by two workers per hour, the production efficiency can be improved by 50%, the labor intensity of workers is greatly reduced, and the number of required overhead traveling cranes is reduced; the quick dismantling and replacing device is simple in structure, convenient to maintain and low in machining cost.
Description
Technical field
The invention belongs to cold rolling production auxiliary equipment technical field, especially relate to a kind of working roll bearing block fast dismantling changing device.
Background technology
The working roll two ends of cold-rolling mill are arranged on two bearing blocks, rotate under the driving of transmission device, complete the rolling function to sheet material.Working roll need to check to bearing block to also have after moving a period of time, working roll after completing the plate rolling of some,, because of the working roll that roll surface wearing need to more renew, all needs to face the dismounting problem of bearing block.
In existing technology, cold rolling factory changes program to bearing seat of operation roll of mill: utilize a day handlebar working roll to winch on roll-changing platform, coordinate again single dismounting bearing block with the people with overhead traveling crane, winch to by the new roller of bearing block to be installed with a day handlebar bearing block after having torn open, the people coordinates single the bearing block new roller of packing into overhead traveling crane again.The length consuming time of above-mentioned working procedure, production efficiency is low, and personnel labor intensity is large.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of working roll bearing block fast dismantling changing device of realizing fast roll changing.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Working roll bearing block fast dismantling changing device, comprise roll change stand, two hydraulic trolley, four tracks that be arranged in parallel and store up the roller stand, each described hydraulic trolley is placed on respectively on two tracks, at central authorities' difference fixed placement roll change stand and the storage roller stand of track.
Preferably, described hydraulic trolley comprises the hydraulic cylinder between vehicle frame, supporting plate and vehicle frame and supporting plate, described bottom of frame fixed installation pulley.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, said apparatus two people per hour can change eight working rolls, can enhance productivity 50%, and worker's labour intensity reduces greatly, and can reduce the overhead traveling crane consumption; The tool apparatus structure is simple, and is easy to maintenance, and processing cost is low.

The specific embodiment
As shown in Figure 1, working roll bearing block fast dismantling changing device of the present invention, comprise roll change stand 3, two hydraulic trolley 4, four tracks that be arranged in parallel 5 and store up roller stand 6, each described hydraulic trolley 4 is placed on two tracks, at central authorities' difference fixed placement roll change stand 3 and the storage roller stand 6 of track.
As shown in Figure 2, described hydraulic trolley 4 comprises the hydraulic cylinder 9 between vehicle frame 7, supporting plate 8 and vehicle frame 7 and supporting plate 8, described vehicle frame 7 bottom fixed installation pulleys 10.
The course of work of this example: the working roll to be changed 1 that utilizes day handlebar to contain bearing block 2 is placed on roll change stand 3, then simultaneously two bearing blocks 2 are lifted to height for convenience detach by two hydraulic trolley 4, the bearing block 2 at quick-detachment working roll 1 two ends, the pulley 10 of hydraulic trolley 4 is along track 5 walkings, the bearing block 2 that transportation disassembles is to the storage roller stand 6 of placing new working roll 1, utilize the liftable function of hydraulic trolley 4, fast bearing block 2 is mounted on new working roll 1.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., within all should still belonging to patent covering scope of the present invention.
