Abstract
An electric lifting appliance special for a cold rolling roller belongs to the technical field of automatic intelligent control. The electric lifting appliance is used for lifting the roller, so that the personnel cost is reduced and the safety factor is improved. The lifting appliance comprises lifting lugs, a driver, a lifting arm, lifting rings and lifting belts, and the lifting function of the roller is achieved through connection among the lifting lugs, the driver, the lifting arm, the lifting rings and the lifting belts. The special electric lifting appliance is suitable for lifting the rollers among the cold-rolled grinding rollers through remote control operation, mainly opens and closes the lifting appliance in a screw transmission mode, and utilizes the specific soft lifting belt to sleeve the rollers, thereby achieving the purpose of automatically lifting the rollers, effectively reducing the labor intensity and safety risk of operators, and more realizing the creation of a good foundation among the intelligent grinding rollers.
Description
Technical Field
The invention belongs to the application of an automatic intelligent control technology, and reduces the personnel cost and improves the safety factor by hoisting and transporting a roller by using an electric lifting appliance.
Background
At present, the working roll/middle roll among the cold rolling grinding rolls is hoisted in a mode of hanging straps manually, so that the manual workload is large, and certain danger exists. The realization of the electric lifting appliance can solve the problem of manual hanging of the lifting belt and realize the operation of the crown block and the lifting of the roller as one man, so that a foundation is laid for the intelligent unmanned grinding roller, the workload and the risk of operators are effectively reduced, and the working efficiency is improved.
SUMMERY OF THE UTILITY MODEL
An electric lifting appliance special for a cold rolling roller is mainly used for reducing the workload and risk of operators and improving the working efficiency.
An electric lifting appliance special for a cold rolling roller mainly comprises a lifting lug 1, a driver 2, a lifting arm 3, a lifting ring 4 and a lifting belt 5.
the lifting lug 1 is fixedly connected with the upper part of the driver 2; the suspension arm 3 is arranged below the driver 2; the hoisting ring 4 is arranged at the lower end of the hoisting arm 3; the hanging strip 5 is mounted on the hanging ring 4.
The lifting lug 1 adopts a plug-in type and is provided with a guide groove,
The driver 2 adopts a lead screw for transmission.
The suspension arm 3 adopts a diagonal inclined design.
The hoisting ring 4 is designed by adopting a pulley.
the lifting lug 1 is inserted and is provided with a guide groove, so that the lifting appliance is convenient to disassemble, and the lifting appliance is effectively prevented from being greatly inclined. The driver 2 adopts a lead screw for transmission, and the stability of the whole mechanism is ensured. The suspension arm 3 adopts an inclined-pulling inclined design, so that the phenomenon of unhooking of the lifting appliance in the lifting process is avoided, and meanwhile, when the roller with the bearing seat is lifted, the bearing seat can be tensioned through the lifting belt, and the overturning is avoided. The lifting rings 4 are designed by adopting pulleys, so that the stability in the lifting and descending processes is ensured, and the lifting belts can be effectively prevented from disengaging from the grooves. The sling 5 is made of high-strength fiber ropes, is a special rope with good elasticity and shape recovery function, when the roller with the bearing block is hoisted, two sides can be tensioned inwards to ensure that the bearing block does not rotate, the radian of the bottom of the roller after being hoisted each time does not change, and the U-shaped part is always kept to be conveniently sleeved at the end part of the roller when the roller is hoisted next time.

Fig. 1 is a structural view of an electric lifting appliance; wherein 1 is a lifting lug, 2 is a driver, 3 is a lifting arm, 4 is a lifting ring, and 5 is a hanging strip.
Detailed Description
An electric lifting appliance special for a cold rolling roller mainly comprises a lifting lug 1, a driver 2, a lifting arm 3, a lifting ring 4 and a lifting belt 5.
The lifting lug 1 is fixedly connected with the upper part of the driver 2; the suspension arm 3 is arranged below the driver 2; the hoisting ring 4 is arranged at the lower end of the hoisting arm 3; the hanging strip 5 is arranged on the hanging ring 4, and the hanging ring 1 adopts a plug-in type and is provided with a guide groove.
The driver 2 adopts a lead screw for transmission.
The suspension arm 3 adopts a diagonal inclined design.
the hoisting ring 4 is designed by adopting a pulley.
In order to make things convenient for ground remote controller operation overhead traveling crane hoist roll more, specially for the electric hoist of overhead traveling crane design work roll and middle roll hoist, the opening and shutting of hoist can utilize remote controller manual control to open and shut according to roll length, make its maximum aperture be 4760mm > longest roller (4350mm), closed narrowest size is 2850mm, the usable hoisting point of all roll shapes is covered to the scope of opening and shutting, this hoist not only possesses the handling smooth roll, also can the handling roll of taking the bearing frame simultaneously, the hoist possesses the function of roll upper and lower roll frame of handling area bearing frame simultaneously, and the hoist can prevent to sway in the handling in-process.
When the smooth rod is hoisted, the sling is opened to the maximum opening degree, the integral posture of the crane or the sling is adjusted, the sling is closed after high-strength fiber ropes at two ends of the sling can be sleeved at two ends of the optical axis, and the lifting is stopped when the rope sleeve reaches a specified hoisting point;
When a roller with a bearing seat is hoisted, the sling is opened to the maximum opening degree, the overall posture of the crane or the sling is adjusted, so that the high-strength fiber ropes at two ends of the sling can be sleeved on exposed optical axes at two ends of the bearing seat, the sling is closed, after the rope sleeve reaches the edge of the bearing seat, the sling is continuously closed, so that the high-strength fiber ropes side of the sling can be tied on the bearing seat, and the sling is lifted;
The high-strength fiber hanging strips at the two ends of the lifting appliance are specially-made ropes with good elasticity and shape recovery functions, when the roller with the bearing seats is lifted, the two sides of the rope can be tensioned inwards to ensure that the bearing seats do not rotate, the radian of the bottom of the roller is not changed after the roller is lifted every time, and the U-shaped rope is always kept to be conveniently sleeved at the end part of the roller when the roller is lifted next time.
