Abstract
The invention discloses a detachment method for screwdown cylinders on a rolling mill. Brackets are arranged on roll changing supports of the rolling mill, the screwdown cylinders are hung on the brackets through a crown block, and rolling changing cylinders are used for pushing the roll changing supports to move forward or backward so as to detach the screwdown cylinders of the rolling mill. The detachment method has the advantages that since the roll changing cylinders on the rolling mill are used for matched detachment, on one hand, the detachment process is quickened, and detachment time is shortened; on the other hand, cylinder damage caused by manual frequent long-time cylinder movement is avoided, and safety and reliability are realized.
Description
Technical field
The present invention relates to the metallurgical machinery equipment technical field, particularly the method for dismounting of depress oil cylinder on a kind of milling train of the band mill unit in stress metal processing workshop.
Technical background
In stress metal processing strip workshop, depress oil cylinder is one of visual plant in the plate rolling process on the milling train, need regularly depress oil cylinder to be overhauled and safeguard, in this process, dismounting and the fixing link of depress oil cylinder are most important, especially for the depress oil cylinder that is installed in upper support roller top, this depress oil cylinder is installed in the rack top, be fixed on the frame top by bolt and nut, overhead very high, the oil cylinder periphery is installed and has been adhered to some pipeline accessories simultaneously.Traditional depress oil cylinder dismounting is to adopt on-the-spot interim frock, needs the wooden protection of cushioning and damping for avoiding the oil cylinder damage, wants many people to cooperate simultaneously, and any one details all may cause the generation of field accident, and this process is loaded down with trivial details consuming time.
Summary of the invention
For overcoming problems of the prior art, the method for dismounting that the purpose of this invention is to provide depress oil cylinder on a kind of milling train, dismounting at the depress oil cylinder that is installed in milling train top backing up roll top, backup roll change support at milling train arranges carriage, hang depress oil cylinder to carriage by overhead traveling crane, utilize advancing or retreating to dismantle the depress oil cylinder of milling train of lower support roller.
For achieving the above object, the present invention adopts following technical scheme:
The method for dismounting of depress oil cylinder on a kind of milling train, this depress oil cylinder is fixedly mounted on the top of rolling-mill housing by screw bolt and nut, be equipped with on the milling train be used to the roll change support that replaces with backing roll, the roll change support is between the upper and lower backing roll on the milling train, the roll change support is fixedly mounted on the bearing block at lower support roller two ends, described roll change support is connected with the roll change oil cylinder, and this roll change oil cylinder is used for promoting roll change support turnover framework memorial archway, and described method for dismounting specifically may further comprise the steps:
A, an end of a screw rod is fixedly connected on the depress oil cylinder, fixedlys connected by steel wire rope between the hook on the other end of described screw rod and the overhead traveling crane;
B, a carriage is fixed on the roll change support by clamping screw, packing ring and alignment pin;
C, the dismounting depress oil cylinder on rolling-mill housing between be connected fastening bolt, nut;
D, utilize the roll change oil cylinder to promote the roll change support, so carriage on the roll change support is synchronized with the movement and arrive the depress oil cylinder that is disassembled under;
E, the hook of overhead traveling crane is slowly fallen, make depress oil cylinder steadily place on the carriage;
F, screw rod one end is unscrewed taking-up from depress oil cylinder, and screw rod sling remove;
G, utilize the roll change oil cylinder to promote the roll change support again, and the roll change support is released framework memorial archway, then depress oil cylinder is taken away and overhauled and safeguard from carriage.
Preferably, the roll change support described in the step b is made up of with the crossbeam that is connected two curb girders two curb girders, and the two ends of crossbeam weld together with two curb girders respectively.
Because adopt aforesaid technical scheme, the present invention has following superiority:
Method for dismounting of the present invention utilizes the roll change oil cylinder that carries on the milling train to cooperate dismounting, accelerated unloading process on the one hand, shortened the take-down time, also avoided artificial frequent, long mobile oil cylinder on the other hand and cause the situation of oil cylinder damage, as safe as a house reliable.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Among the figure: the 1-overhead traveling crane; The 2-screw rod; The 3-depress oil cylinder; The 4-carriage; The 5-clamping screw; 6 roll change supports; The 7-milling train.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the method for dismounting of depress oil cylinder on a kind of milling train, this depress oil cylinder 3 is fixedly mounted on the top of milling train 7 frames by screw bolt and nut, be equipped with on the milling train 7 be used to the roll change support 6 that replaces with backing roll, roll change support 6 is between the upper and lower backing roll on the milling train, roll change support 6 is fixedly mounted on the bearing block at lower support roller two ends, described roll change support 6 is connected with the roll change oil cylinder, this roll change oil cylinder is used for promoting roll change support turnover framework memorial archway, and described method for dismounting specifically may further comprise the steps:
A, an end of a screw rod 2 is fixedly connected on the depress oil cylinder 3, fixedlys connected by steel wire rope between the hook on the other end of described screw rod 2 and the overhead traveling crane 1; According to weight or the on-the-spot practical operation situation of depress oil cylinder, select for use the screw rod of suitable dimension, performance to be used for the lifting depress oil cylinder;
B, a carriage 4 is fixed on the roll change support 6 weldment that described roll change support 6 is made up of two curb girders and the crossbeam that is connected two curb girders by clamping screw 5, packing ring and alignment pin;
C, the dismounting depress oil cylinder on rolling-mill housing between be connected fastening bolt, nut;
D, utilize the roll change oil cylinder to promote roll change support 6, so carriage 5 on the roll change support is synchronized with the movement and arrive the depress oil cylinder 3 that is disassembled under;
E, the hook of overhead traveling crane 1 is slowly fallen, depress oil cylinder 3 is steadily placed on the carriage 5; On the described carriage 5 the overcoat pad can be set, the damage of colliding with in the time of can avoiding depress oil cylinder to put off on the carriage;
F, screw rod 2 one ends are unscrewed taking-up from depress oil cylinder 3, and screw rod sling remove;
G, utilize the roll change oil cylinder to promote roll change support 6 again, and the roll change support is released framework memorial archway, then depress oil cylinder 3 is taken away and overhauled and safeguard from carriage 5.
