Description

Rolled piece head tilting alarm device

Technical Field

The utility model relates to the technical field of hot rolling safety equipment, in particular to a rolled piece head tilting alarm device.

Background

In a rough rolling double-stand continuous rolling system of a hot rolling plate and strip mill, rolled pieces need to be rolled from one rolling mill and then enter the other rolling mill for rolling, the condition that the rolled pieces turn up occurs in the process of rolling out from the former rolling mill to entering the latter rolling mill, whether the turn-up height of the rolled pieces can smoothly enter the latter rolling mill can only be judged through experience of operators, once the operators judge that errors or focus is not enough, the rolled pieces can strike a rolling mill guide to be waste steel, and the rolling mill guide can be damaged under multiple striking; in order to prevent the impact between the rolled piece and the rolling mill guide, a baffle is installed on a set height between two rolling mills, and the rolled piece is impacted by the baffle when the warping head of the rolled piece reaches a certain height so as to prevent the rolled piece from directly impacting the rolling mill guide and protect the rolling mill guide from damage.

Disclosure of Invention

The utility model aims to provide the rolled piece head-tilting alarm device which can prompt rolled piece tilting in time and can prevent the rolled piece from being changed into scrap steel under the condition of preventing the rolled piece from being impacted with a guide of a rolling mill.

In order to solve the problems, the utility model adopts the following technical scheme: this kind of rolled piece seesaw alarm device, including two relative stands that set up, two the top of stand is transversely put up a round bar, the round bar is two be equipped with long jib between the stand, the top of long jib with round bar fixed connection, the one end of round bar is equipped with short jib, the top of short jib with round bar fixed connection, the bottom of short jib is connected with travel switch's pendulum rod through the rope, travel switch's signal terminal is connected to buzzer siren and remote computer through control unit.

Among the above technical schemes, more specific technical schemes may also be: the control unit is a PLC, a normally open contact of the travel switch is connected with a switching value input module DI point of the PLC, and the buzzer alarm and a signal receiving end of the remote computer are connected with a switching value output module DO point of the PLC.

Further, the top of the long suspender is provided with a circular ring sleeved on the circular rod, and the inner annular wall of the circular ring is fixedly connected with the outer annular wall of the circular rod.

Further, the top of stand is equipped with the U type groove of undercut, the round bar crimping in the tank bottom of U type groove, U type groove wears to be equipped with first stop bolt on the cell wall of round bar top.

Further, the round rod is provided with second limit bolts at the outer sides of the two upright posts.

Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:

the utility model can prompt and alarm the head-tilting condition of the rolled piece timely and effectively, so that operators can take countermeasures timely when the head-tilting of the rolled piece occurs, the impact between the rolled piece and a rolling mill guide can be prevented, the rolled piece can be prevented from becoming scrap steel, the scrap steel rate of the rolled piece is greatly reduced, rolling mill equipment is protected, and the production of a production line is ensured to be smooth.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a view in the K-direction of fig. 1.

Detailed Description

The utility model is further described in detail below with reference to the examples of the drawings:

the rolled piece head-tilting alarm device shown in fig. 1 and 2 comprises two upright posts 1 which are oppositely arranged, wherein a round rod 2 is transversely arranged at the top of each upright post 1, a long hanging rod 3 is arranged between the two upright posts 1 by the round rod 2, a circular ring 3-1 sleeved on the round rod 2 is arranged at the top of the long hanging rod 3, an inner annular wall of the circular ring 3-1 is fixedly connected with an outer annular wall of the round rod 2, a short hanging rod 4 is arranged at one end of the round rod 2, the top of the short hanging rod 4 is fixedly connected with the round rod 2, the bottom of the short hanging rod 4 is connected with a swinging rod of a travel switch 6 through a rope 5, and a signal end of the travel switch 6 is connected to a buzzer alarm 8 and a remote computer 9 through a control unit 7.

The top of the upright column 1 is provided with a U-shaped groove which is sunken downwards, the round rod 2 is in press connection with the bottom of the U-shaped groove, and the U-shaped groove is provided with a first limit bolt 10 in a penetrating way on the groove wall above the round rod 2; the round bar 2 is provided with a second limit bolt 11 on the outer sides of the two upright posts 1.

In this embodiment, the control unit 7 is a PLC, the signal end of the travel switch 6 is a normally open contact, the normally open contact of the travel switch 6 is connected with the switching value input module DI point of the PLC, and the signal receiving ends of the buzzer alarm 8 and the remote computer 9 are connected with the switching value output module DO point of the PLC.

When in use, the utility model is respectively arranged at a rolled piece outlet guide part close to a former rolling mill and a rolled piece inlet guide part close to a latter rolling mill, two upright posts 1 are fixed at two sides of a rolled piece running path, a long suspender 3 is arranged at a limited height on the rolled piece running path, and a shell of a travel switch 6 is fixed on an object beside the upright posts 1. Under normal conditions, the long suspender 3 and the short suspender 4 are in a vertical downward state, when the rolled piece is warped to strike the long suspender 3, the long suspender 3 drives the round rod 2 to rotate, so that the short suspender 4 swings along with the long suspender, at the moment, the short suspender 4 drives the swing rod of the travel switch 6 to act through the rope 5, the normally open contact of the travel switch 6 is closed, the switching value input module DI point of the PLC obtains an input signal, the switching value output module DO point triggers the buzzer alarm 8 to send buzzing alarm sound, meanwhile, the remote computer popup window alarm is triggered, at the moment, an operator controls the rolling mill to reversely rotate to level the rolled piece and roll the rolled piece again, the rolled piece is prevented from striking the rolling mill to be waste steel, and meanwhile, the rolling mill safety is protected.

The remote computer 9 can not only pop a window for alarming, but also count the number of times of head tilting of rolled pieces, and timely process and adjust the equipment when the head tilting is too frequent. The long suspender 3 is used as a part for the rolled piece tilting head impact, the impact area is small, the rolled piece is prevented from being damaged, and the long suspender 3 is prevented from being influenced by high-pressure water injection of a rolling mill, so that a false alarm condition is caused. The first limit bolt 10 is used for preventing the round rod 2 from being fleed out of the U-shaped groove, and the second limit bolt 11 is used for preventing the round rod 2 from moving left and right.
