Problems solved by technology

When the width of the coil is narrow, the diameter-to-width ratio of the coil will be too large, the center of gravity will be unstable, and shaking will often occur during the loading and unloading process. Improper operation will even cause serious accidents such as the rollover of the coil, resulting in personal injury and equipment damage. damage, property loss

no. 1 approach

[0029] The first embodiment of the present invention relates to an anti-overturn loading and unloading trolley, such as figure 1 As shown, it includes a hollow trolley body 6, and a lifting base 5 placed in the trolley body 6 and capable of lifting in the vertical direction. The top of the lifting base 5 is fixed with a lifting platform 8 positioned above the trolley body 6, A number of double-rod hydraulic cylinders 4 are arranged below the lifting platform 8, and an idler seat is installed in the upper middle of the lifting platform 8, and two idler rollers 1 are arranged side by side on the idler seat for supporting the coil The lifting platform 8 is also hinged with some clamping devices for clamping the two sides of the coil, and several clamping devices are symmetrically arranged on the axial ends of the idler 1 in groups of two, and each group of clamping devices The lower end passes through the lifting platform 8 and is connected with the piston rod of a double-rod hyd...

no. 2 approach

[0034] This embodiment provides an anti-overturn loading and unloading trolley, such as figure 2 As shown, it includes a hollow trolley body 6, and a lifting base 5 placed in the trolley body 6 and capable of lifting in the vertical direction. The top of the lifting base 5 is fixed with a lifting platform 8 positioned above the trolley body 6, A number of double-rod hydraulic cylinders 4 are arranged below the lifting platform 8, and an idler seat is installed in the upper middle of the lifting platform 8, and two idler rollers 1 are arranged side by side on the idler seat for supporting the coil The lifting platform 8 is also hinged with some clamping devices for clamping the two sides of the coil, and several clamping devices are symmetrically arranged on the axial ends of the idler 1 in groups of two, and each group of clamping devices The lower end passes through the lifting platform 8 and is connected with the piston rod of a double-rod hydraulic cylinder 4; specifically...

no. 3 approach

[0036] On the basis of the above embodiment, further, the lifting platform 8 is also provided with a number of positioning plates 9, the positioning plates 9 are vertically welded to both sides of the connecting rod 3 in pairs, and the positioning plates 9 A pin shaft hole is arranged on the top, and a positioning long hole is provided at the lower end of the connecting rod 3 , and the pin shaft passes through the pin shaft hole and the positioning long hole to hinge the connecting rod 3 between the two positioning plates 9 . It is worth mentioning that the connecting rod 3 can rotate around the pin shaft driven by the double-rod hydraulic cylinder 4, and the pin shaft can move in a small range along the vertical direction of the long positioning hole to ensure that the connecting rod 3 is flexible at the hinge axis. turn.

Abstract

The invention provides an anti-tipping coil loading and unloading trolley and a using method thereof. The anti-tipping coil loading and unloading trolley comprises a hollow trolley body and a liftingbase arranged in the trolley body and capable of ascending and descending in a vertical direction; a lifting platform is fixed to the top of the lifting base; a plurality of double-outlet-rod hydraulic cylinders are arranged below the lifting platform; a carrier roller base is installed in the middle of the upper portion of the lifting platform; two carrier rollers are arranged on the carrier roller base side by side and used for supporting coiled materials; a plurality of clamping devices are further hinged to the lifting platform; the multiple clamping devices are symmetrically arranged at the two axial ends of the carrier roller in pairs; the lower ends of each clamping device group penetrate through the lifting platform and are connected with a piston rod of a double-outlet-rod hydraulic cylinder; and the double-outlet-rod hydraulic cylinders control the clamping devices to clamp or loosen the coiled materials supported on the carrier rollers. A connecting rod is driven by the double-outlet-rod hydraulic cylinder to rotate to drive a pressing plate to clamp a coiled material, and the problems that shaking is likely to happen in the coil loading and unloading processes, and tipping is likely to happen in a serious situation are solved.

Description

technical field [0001] The invention belongs to the field of cold rolling mill equipment, and in particular relates to an anti-tipping coil loading and unloading trolley and a use method thereof. Background technique [0002] The coil loading and unloading trolley is the necessary equipment of the cold rolling mill. The traditional coil loading and unloading trolley is driven by a motor and lifted by an oil cylinder. When coiling, the coil to be rolled is transported from the saddle to the reel of the uncoiler; otherwise, when the coil is unloaded, the rolled coil is transported to the saddle. When the width of the coil is narrow, the diameter-to-width ratio of the coil will be too large, the center of gravity will be unstable, and shaking will often occur during the loading and unloading process. Improper operation will even cause serious accidents such as the rollover of the coil, resulting in personal injury and equipment damage. damage, property loss. Contents of the ...
