Abstract

The utility model discloses a kind of closed type rolling mill press head safety anti-falling device, this device includes suspension ring, chain and connection ring, and described suspension ring are fixed on mill housing, and connection ring is fixed on rolling mill press head side, one end of chain is connected on suspension ring, and the other end is connected in connection ring.Can prevent closed type rolling mill press head from falling using this device and personnel casualty accidentses or device damage occur.

Description

A kind of closed type rolling mill press head safety anti-falling device

Technical field

This utility model belongs to field of metallurgy, is related to a kind of safety device, specifically a kind of closed type rolling mill press head peace Full anti-fall device.

Background technology

In prior art, closed type rolling mill press head leans on the gland of two semi-ring compositions to be connected to pressure head by fixing bolt At down screw rod step.See Fig. 1, in Fig. 1,11- rolling mill press head, 12- down screw rod, 13- pressure head bearing, 14- pressure head gland, 15- fixing bolt.The down screw rod head step pull-up pressure head pressure when closed type milling train topping roll adjusts upward or changes roll Cover strip moves rolling mill press head action upwards together, occurs sliding friction to produce with pressure head gland certain at down screw rod head step Abrasion.When being negligent of inspection and observing, after life-time service abrasion, pressure head gland easily falls at down screw rod head step, occurs The pressure head falling injures the accident of the equipment such as personnel or roll change roller-way by a crashing object.

Content of the invention

In order to overcome problems of the prior art, the purpose of this utility model is to provide a kind of closed type rolling mill press head Safety anti-falling device, can prevent closed type rolling mill press head from falling using this device and personnel casualty accidentses or device damage occur.

The purpose of this utility model is achieved through the following technical solutions：

A kind of closed type rolling mill press head safety anti-falling device it is characterised in that：This device includes suspension ring, chain and connection Ring, described suspension ring are fixed on mill housing, and connection ring is fixed on rolling mill press head side, and one end of chain is connected on suspension ring, The other end is connected in connection ring.

Further, suspension ring are welded on mill housing, and connection ring is welded on rolling mill press head side.The length of chain and roll change Or the displacement of rolling mill press head is adapted during adjustment roll gap.

This utility model is respectively welded on mill housing and pressure head side and fixes suspension ring and connection ring, is closed with one Pressure head and mill housing are connected by the chain of suitable length.When roll change or adjustment roll gap, chain does not affect associative operation, and once When occurring pressure head to fall, chain will prevent pressure head from falling.

This utility model can prevent from occurring pressure head to fall the accident of causing casualties or equipment during closed type mill roll Damage.

Brief description

Fig. 1 is the connected mode schematic diagram of rolling mill press head in prior art.

Fig. 2 is structural representation of the present utility model.

In Fig. 2,1- suspension ring, 2- chain, 3- connection ring, 4- mill housing, 5- rolling mill press head, 6- down screw rod, 7- pressure head Gland, 8- pressure head bearing, 9- fixing bolt.

Specific embodiment

A kind of closed type rolling mill press head safety anti-falling device, is shown in Fig. 2, and this device includes suspension ring 1, chain 2 and connection ring 3, Suspension ring are welded on mill housing 4, and connection ring is weldingly fixed on rolling mill press head 5 side, and one end of chain is connected on suspension ring, separately One end is connected in connection ring.The length of chain is adapted with the displacement of rolling mill press head 5 when roll change or adjustment roll gap.

Strip mill φ 650 h roughing mill pressure head and Continuous mill train four-high mill pressure head all occurred multiple pressure head to fall thing Part, is all because the abrasion of pressure head gland causes pressure head to come off at down screw rod head step.In mill housing and pressure head side On be respectively welded the suspension ring fixing a φ 60 and connection ring, the φ 8mm chain being about 0.5 meter with an appropriate length is by pressure head Connect with mill housing.When roll change or adjustment roll gap, chain does not affect associative operation, and when occurring pressure head to fall, chain Bar is effectively prevented pressure head from falling it is ensured that pressure head will not be occurred to fall injure personnel or equipment by a crashing object.
