According to the requirements of rolling process, horizontal rolling mills and vertical rolling mills are used for a steel rolling main rolling line and are arranged in a staggered mode, a vertical rolling mill core is clamped and fixed through a vertical clamping cylinder, the rolling mill core is kept stable in the steel rolling process, and the rolling quality can be influenced if the rolling mill core shakes, deviates and the like.
When the clamping cylinder has oil leakage, internal leakage and other faults, the clamping cylinder needs to be dismantled and maintained offline. The clamping cylinder is provided with a hoisting hole, so that the vertical hoisting is facilitated. In the actual maintenance and dismantling process, the clamping cylinder is horizontally installed, so that the hoisting hole cannot meet the requirement of safely hoisting the clamping cylinder. As shown in fig. 1, the clamping cylinder can only be strapped to the cylinder barrel by means of a wire rope and removed from the machine frame using a travelling crane. However, the clamping cylinder is heavy in weight, the center of gravity is easy to shift, steel wire ropes are not tied firmly, potential safety hazards such as overturning and sliding are easy to occur in the hoisting process, operation risks exist, and personal safety of maintainers is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a vertical rolling mill presss from both sides tight jar to overhaul and uses safe hoist is provided to above-mentioned prior art, satisfies the operation scene and presss from both sides tight jar handling and installation demand, avoids the handling in-process to press from both sides tight jar and topples, landing, guarantee operation personnel's personal safety.
The utility model provides a technical scheme that above-mentioned problem adopted does: a safety lifting appliance for overhauling a clamping cylinder of a vertical rolling mill comprises a bottom plate for supporting a horizontal clamping cylinder, wherein a vertical plate is arranged on the bottom plate, so that a rear end cover of the clamping cylinder is abutted against the vertical plate; a plurality of locking holes are formed in the vertical plate in the circumferential direction and correspond to bolt holes in the rear end cover of the clamping cylinder, and locking bolts penetrate through the locking holes and the bolt holes in the rear end cover of the clamping cylinder, so that the vertical plate is fixedly connected with the clamping cylinder; the bottom plate is provided with a plurality of lifting lugs for connecting and hoisting steel wire ropes.
The length of the bottom plate is 70-80 mm smaller than that of the clamping cylinder, and the width of the bottom plate is matched with that of the clamping cylinder.
The lifting lugs are distributed at four corners of the bottom plate, and the lifting lugs are arranged in a pairwise symmetrical mode.
Compared with the prior art, the utility model has the advantages of: the utility model provides a vertical rolling mill presss from both sides tight jar and overhauls and uses safe hoist, will press from both sides tight jar and crouch on the bottom plate, and press from both sides tight jar rear end cap and support in the riser, wear to establish from threaded hole and locking downthehole on pressing from both sides tight jar rear end cap through the locking bolt for press from both sides tight jar and riser fixed connection, satisfied the on-the-spot tight jar handling of clamp of operation and installation demand, avoided the handling in-process to press from both sides tight jar and topple, the landing, ensured operation personnel's personal safety.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 2, 3, and 4, the safety lifting appliance for overhauling the clamping cylinder of the vertical rolling mill in the embodiment includes a bottom plate 1, a vertical plate 2 is vertically disposed on one side of the bottom plate 1, a horizontal clamping cylinder 5 is disposed on the bottom plate 1, the placement direction of the clamping cylinder 5 is consistent with the field installation direction, and the rear end cover of the clamping cylinder 5 is abutted to the vertical plate. 6M 16 × 60mm bolts are arranged on the rear end cover of the clamping cylinder 5 in a penetrating way, and the rear end cover is fixedly connected with the cylinder body of the clamping cylinder 5 through the bolts. 4 locking holes 4 are formed in the vertical plate 2 in the axial direction, the positions of the locking holes 4 correspond to the positions of 4 bolts on the rear end cover of the clamping cylinder 5, and the diameter of each locking hole 4 is phi 18 mm. When the clamping cylinder 5 is overhauled, 4 bolts on the rear end cover of the clamping cylinder 5 are removed, 4 rear end cover bolt holes are exposed, and the other two bolts are still fixedly connected with the rear end cover and the clamping cylinder 5 cylinder body. And (3) penetrating the locking bolt 7 with M16 × 80mm into the corresponding locking hole 4 and bolt hole, so that the vertical plate 2 is fixedly connected with the clamping cylinder 5 on the bottom plate 1. Be equipped with 4 lugs 3 on the bottom plate 1, lug 3 distributes in four corners of bottom plate 1, and 3 bisymmetry settings of lug, connect the wire rope 6 of handling respectively in the lug 3, through the safe hoist of driving handling fixed clamp jar 5 for press from both sides the 5 handling of clamp jar to overhauing the position. After the maintenance is finished, the clamping cylinder 5 is lifted to the mounting position, 4M 16 x 80mm locking bolts 7 are unscrewed, and 4M 16 x 60mm bolts are screwed into bolt holes of the rear end cover.
The length of the bottom plate 1 is 75mm less than that of the clamping cylinder 5, so that a piston rod of the clamping cylinder 5 can be conveniently pushed into a mounting seat of a rolling mill frame. The width of the bottom plate 1 is matched with the width of the clamping cylinder 5, so that the bottom plate 1 is ensured to stably support the clamping cylinder.
This application will press from both sides tight jar and crouch on the bottom plate, and press from both sides tight jar rear end cap and support in the riser, wear to establish self screw hole and locking hole on the tight jar rear end cap of clamp through the locking bolt for press from both sides tight jar and riser fixed connection, satisfied operation scene press from both sides tight jar handling and installation demand, avoided handling in-process to press from both sides tight jar and topple, the landing, ensured operation personnel's personal safety.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
