Description

Roll changing lifting appliance of roller coater in narrow space

Technical Field

The utility model belongs to the technical field of continuous hot galvanizing line equipment, concretely relates to narrow and small space roller coater roll change hoist.

Background

In-process of roller coater roll change in narrow and small space, personnel receive easily that the restriction of lifting by crane equipment leads to personnel station safe distance not enough, receive the influence of height still to lead to unable installation electric hoist to hang or other equipment of lifting by crane, when using equipment such as chain block to carry out the operation, often unable pulling when the great atress direction pulling chain of gradient, often the jam, can not normal use, personnel need stand and operate under the hanging object that is close to the handling, can't guarantee personnel's safe distance, the unreasonable or the heavy operation that is unfavorable for the scene of design of hoist.

The safety of operation in narrow and small space can not be guaranteed, the roll changing time is longer, the main problem that exists is that a new roll is installed after an old roll is lifted out in the roll changing process, the roll surfaces of a coating roll and a strip roll of the roll coater can not be touched by other external force in the changing process, the damage to the roll surface is easily caused, the roll changing efficiency is greatly reduced, the accidental temporary roll changing operation during normal production is not facilitated, the roll changing operation needs to be completed in the shortest time, contradiction exists between the coating roll and the strip roll, the industrial design environment and the cost are considered, basically, a plurality of standby roll coaters are fewer, the roll coater needs to be stopped and replaced in serious conditions, a large amount of waste products and degraded products are produced, the cost is increased, and the stable production is not facilitated. There is the platform of steel construction in the roller coat machine top in addition, there is interference easily with the gib head of overhead traveling crane in the orbital end that stretches out of chain block above the roller coat machine, when the lifting hook of overhead traveling crane lifting hook and chain block switched over each other, there is interference in roll change hoist and overhead traveling crane gib head and wire rope, position adjustment that needs to relapse, personnel are not enough in safe station position in the operation of below, especially when using wire rope as the hoisting point of switching, wire rope is crooked more easily, there is torsion, the in-process of hanging on the lifting hook is more time-consuming and energy-consuming, switching time is long.

SUMMERY OF THE UTILITY MODEL

The utility model provides a narrow and small space roller coater roll change hoist, includes the hoist crossbeam, the top of hoist crossbeam is provided with rings, plane link mechanism has been installed respectively at the below both ends of hoist crossbeam, the clip is installed to plane link mechanism's lower extreme, plane link mechanism is used for opening or presss from both sides tight clip, the clip is used for the centre gripping roller.

Preferably, the lifting ring is of an L-shaped structure, and lifting hook connecting holes are formed in two ends of the lifting ring of the L-shaped structure.

Preferably, the lifting ring is movably connected with the lifting appliance cross beam through a pin shaft.

The utility model has the advantages that:

(1) the utility model discloses a narrow and small space roller coater roll change hoist, it designs rings through the hoist crossbeam top, designs plane link mechanism and clip below the hoist crossbeam, when hoisting up the hoist through the rings for hoisting equipment, utilizes the working characteristic of plane link mechanism and the gravity of roller self, with the clip with the firm rings of clip of roller, its simple structure simultaneously, can hang out the roller of roller coater in narrow and small space and change and install;

(2) the utility model discloses be L type structure with the ring design, rings are with round pin axle and hoist crossbeam swing joint simultaneously, and rings can be at the junction free rotation of hoist crossbeam promptly, have made things convenient for the power switching of overhead traveling crane gib head and calabash gib head like this, keep safe distance and reliable connection between two hoisting equipment, make things convenient for personnel's safety work.

fig. 2 is a top view of the present invention;

fig. 3 is a side view of the present invention;

fig. 4 is an isometric view of the present invention;

in the figure: 1. the lifting appliance comprises a lifting appliance beam, 2 lifting rings, 5 clamps, 6 pin shafts, 8 plane connecting rod mechanisms and 10 rollers.

Detailed Description

The invention will be further described with reference to the accompanying drawings and working principles:

the roller changing lifting appliance of the roller coating machine in the narrow space shown in fig. 1-4 comprises a lifting appliance cross beam 1, a lifting ring 2 is arranged above the lifting appliance cross beam 1, the lifting ring 2 is used for being connected with a lifting equipment crown block, a chain block and the like, two ends of the lower part of the lifting appliance cross beam 1 are respectively provided with a plane connecting rod mechanism 8, the lower end of the plane connecting rod mechanism 8 is provided with a clamp 5, the plane connecting rod mechanism 8 is used for opening or clamping the clamp 5, and the clamp 5 is used for clamping a roller 10. Rings 2 are L type structure, there is the lifting hook connecting hole at L type structure rings 2's both ends, rings 2 are through round pin axle 6 and 1 swing joint of hoist crossbeam, rings 2 of L type structure can rotate through round pin axle 6 and hoist crossbeam 1's junction, made things convenient for overhead traveling crane lifting hook and chain block lifting hook simultaneously can be connected with the couple of hoist like this, simultaneously because rings 2 are L type structure, hang two hoisting apparatus's of heavy object wire rope or gib head and be difficult to touch and twine, certain safe distance has been kept, the roller position amplitude of swing of narrow and small space roller coater roll change hoist is not big, it is not rotatory at will, it is less in narrow and small space operation restraint, more be favorable to carrying out the adjustment of angle and position.

When the roller hanger is used, firstly, connecting holes at two ends of a lifting ring 2 of an L-shaped structure are respectively connected with a lifting hook of a crane and a lifting hook of a chain block, when a roller 10 of a roller coater is disassembled, a hanger is firstly placed on the roller 10 of the roller coater, two clamps 5 of the hanger are positioned at two ends of the roller 10, then when a hanger beam 1 of the hanger is stressed by the chain block, the roller 10 is firmly clamped by the clamps 5 by utilizing the self-gravity of the roller 10 and the tension of the hanger beam 1, the roller 10 is lifted away from the roller coater by utilizing the self-working characteristic of the plane connecting rod mechanism 8, and after the roller 10 is lifted away from a narrow space of the roller coater by utilizing the rotating characteristic of the lifting ring 2, the roller 10 is lifted by utilizing the lifting hook, and the disassembly; when the roller 10 of the roll coater is installed, the roller 10 is firmly clamped by two clamps 5 according to the detaching process, firstly, the roller 10 is hung to the position of the roller 10 needing to be installed by a crown block, and the roller 10 is hung into a narrow installation environment by a chain block of the roll coater. Make things convenient for overhead traveling crane lifting hook and chain block lifting hook simultaneously can be connected with the couple of hoist like this, simultaneously because rings 2 are L type structure, the wire rope or the gib head of two hoisting equipment of hanging the heavy object are difficult to touch and twine, have kept certain safe distance, and the roller position swing range of narrow and small space roller coater roll change hoist is not big, and is not rotatory at will, and is less in narrow and small space operation restraint, more is favorable to carrying on the adjustment of angle and position.
