Abstract
The invention relates to a roller bed bearing fast replacement method which comprises the following steps of (1) with regard to the oversmall slit between a roller bed and the lower portion of a box type or frame type structure device arranged above, designing the lower portion of a box body into a detachable movable plate, and firstly dismantling the corresponding movable plate in operation; (2) after dismantling foundation bolts and connectors of the roller bed, utilizing a first hydraulic jack to jack up a bearing seat on one side of the roller bed until a base clamping groove is separated from the foundation, hoisting a first clamp to be horizontal to serve as a force bearing support through a crane, grabbing the bearing seat out through a second hydraulic jack matched with a second clamp, directly cutting the old bearing or dismantling the old bearing through a hydraulic claw, and installing the new bearing. Compared with the prior art, the roller bed bearing fast replacement method has the advantages of being matched with the hydraulic jacks, fully utilizing onboard space, performing bearing fast replacement, effectively avoiding heavy work caused by assembling or disassembling the device above the roller bed, improving efficiency on replacement of the roller bed bearing, saving overhaul time, reducing labor intensity, reducing overhaul cost and improving the starting rate of the device.
Description
Technical field
The present invention relates to steel rolling equipment technical field, particularly a kind of roller-way bearing quick change method.
Background technology
Roller-way is the visual plant on steel rolling production-line, and it is being born is the task that whole production line transmits steel plate.The replacing of roller-way bearing is the most important thing in steel rolling equipment maintenance work especially.The conventional method of roller-way bearing replacing is that the roller-way that disintegrates again after the lower machine of roller-way dismounting is carried out to the replacing of bearing.For top, arranged the roller-way of other equipment, conventional method must first be removed top device, and the workload of many times top device dismounting can be tens times of the own workload of roller-way bearing replacing.Traditional method has taken the precious resources such as repair time and maintenance manpower in a large number, directly reduces equipment and can start rate and improve cost of equipment maintenance.
Summary of the invention
The object of this invention is to provide a kind ofly not removing under the condition of top device, directly roller-way bearing is carried out to quick-replaceable method.
For achieving the above object, the present invention realizes by the following technical solutions:
A bearing quick change method, comprises the following steps:
1) under the box or closed-in construction equipment of arranging for top along and roller-way between gap be less than or equal to 20cm, the bottom of upper square box is designed to removable portable plate, during operation, first remove corresponding portable plate;
2) remove after roller-way foundation bolt and catcher, by hydraulic jack one, roller-way one side shaft holder jack-up to seat end draw-in groove is departed to basis, fixture one use crane is hung flat as stress support, by hydraulic jack two, coordinate fixture two that bearing block is caught, old bearing is directly cut or grabs dismounting with hydraulic pressure, then with hot charge practice, new bearing is installed, return dress bearing housing.
Described fixture one is U-shaped structure.
Described fixture two is the rectangle frame that a side is provided with opening.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of roller-way bearing quick change method, owing to coordinating small-sized hydraulic jack, make full use of space on machine, on machine, carried out the operation of bearing quick-replaceable, effectively avoided the hard work of dismounting roller-way top device, improve the efficiency of roller-way bearing replacing work, reduce taking of repair time and manpower, save the cost of overhaul and improve the started rate of equipment.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
Embodiment mono-
As shown in Figure 3 and Figure 4, take De-scaling box roller-way as example, a kind of roller-way bearing of the present invention quick change method, comprises the following steps:
1) bottom of square box on the casing of De-scaling box 5 roller-ways need be designed to removable portable plate 6, then the portable plate 6 for the treatment of operation roller-way top be removed, facilitate roller-way on machine, by jack, to be promoted by a small margin;
2) below roller-way, place hydraulic jack 1, roller-way is pushed up to bearing block below draw-in groove and departs from the position of pedestal completely, by hydraulic jack 1, roller-way one side shaft holder 7 jack-up to seat end draw-in groove is departed to basis, fixture one 1 use cranes are hung and put down as stress support, by hydraulic jack 24, coordinate fixtures 22 that bearing block 7 is caught, then directly change roller-way bearing, bearing block is being filled for 7 times, roller-way falls after rise, and portable plate returns dress, has completed operation.
As shown in Figure 1, above-mentioned fixture 1 is U-shaped structure.
As shown in Figure 2, above-mentioned fixture 22 is the rectangle frame that a side is provided with opening.
Above described in be only basic principle of the present invention, not the present invention is imposed any restrictions, everyly according to the present invention, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
Claims (3)
