The following description of the embodiments of the present invention will be described in more detail with reference to the drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
As shown in fig. 1, the present embodiment provides a roll lifting device for lifting a roll onto a grinding machine, including:
the overhead rail 10 is arranged along the transverse direction, and a plurality of first iron blocks 21 are arranged on the overhead rail 10 along the transverse direction;
the roller device comprises a plurality of bridge cranes, wherein each bridge crane comprises a cart 30 and a trolley 40, the rollers are arranged on the trolley 40, the cart 30 can transversely move along the elevated rail 10 to drive the trolley 40 and the rollers to transversely move, a guide rail is longitudinally arranged on the cart 30, the trolley 40 is arranged on the guide rail and can longitudinally move along the guide rail to drive the rollers to longitudinally move, and a plurality of second iron blocks 22 are longitudinally arranged on the guide rail;
the first alarm component comprises a first alarm 51 and a first inductive switch 61 which are connected with each other, and when the first inductive switch 61 senses the first iron block 21, the first alarm 51 gives an alarm;
and the second alarm component comprises a second alarm 52 and a second inductive switch 62 which are connected with each other, and when the second inductive switch 62 senses the second iron block 22, the second alarm 52 gives an alarm.
Specifically, the elevated rail 10 is generally transversely disposed in a factory building, a workshop, a warehouse, or the like, and is used for the bridge crane to transversely travel. In this embodiment, the elevated rail 10 is disposed in a grinding factory, and the length of the elevated rail is greater than 100 meters, and a plurality of grinding machines, for example, three grinding machines, are disposed in the factory, which is not limited in this application. A plurality of first iron blocks 21 are transversely arranged on the elevated rail 10, and the first iron blocks 21 respectively correspond to the transverse positions of different grinding machines. In this embodiment, the number of the grinding machines is three, so that the number of the first iron blocks 21 is three.
The overhead crane can travel laterally on the elevated rail 10 for hoisting and unloading the rolls to and from the mill. In this embodiment, the bridge crane includes a cart 30 and a trolley 40, the cart 30 can drive the roller to move transversely, and the trolley 40 is used for adjusting the longitudinal position of the roller. Of course, the bridge crane may further include a lifting mechanism, a driving mechanism, and other devices for realizing the functions of raising or lowering the roller, and the description of the present application is omitted. The cart 30 is longitudinally provided with a guide rail, the guide rail is longitudinally provided with a plurality of second iron blocks 22, and the second iron blocks 22 correspond to the longitudinal positions of different grinding machines. In this embodiment, the number of the second iron blocks is also 3.
With reference to fig. 1, the roll lifting device further includes a first alarm component, the first alarm component includes a first alarm 51 and a first inductive switch 61, which are connected to each other, and when the first inductive switch 61 senses the first iron block 21, the first alarm 51 gives an alarm. When the first inductive switch 61 senses the first iron block 21, it indicates that the cart 30 has reached the set transverse position, and at this time, the first alarm 51 gives an alarm to prompt an operator to control the cart 30 to stop.
It should be understood that, because the length of the elevated rail 10 is long and the distance between the grinding machines is large, the distance between the three first iron blocks 21 is also large, and the situation that the transverse position of the cart 30 is disordered does not occur in combination with simple judgment of the naked eyes of an operator. For example, when the cart 30 needs to be run to the farthest grinding machine, the first inductive switch 61 will sense three first iron blocks 21 one by one, and the first alarm 51 can give an alarm, but after the first two alarms, when the first inductive switch 61 senses the last first iron block 21, the operator will control the cart 30 to stop.
With reference to fig. 1, the roll lifting device further includes a second alarm component, which includes a second alarm 52 and a second inductive switch 62 connected to each other, and when the second inductive switch 62 senses the second iron block 22, the second alarm 52 gives an alarm. When the second inductive switch 62 senses the second iron block 22, it indicates that the trolley 40 has reached the set longitudinal position, and at this time, the first alarm 51 gives an alarm to prompt an operator to control the trolley 40 to stop. It will be appreciated that when the trolley 40 reaches the set longitudinal position, with the roll directly above the mounting position, the roll is simply lowered down and mounted to the grinding machine by the lifting mechanism to complete the up-grinding operation of the roll. The transverse movement of the cart 30 is sensed and alarmed through the first alarming component, and then the longitudinal movement of the trolley 40 is sensed and alarmed through the second alarming component, so that an operator can accurately position the cart 30 and the trolley 40, the roller can accurately reach the mounting position on the grinding machine after falling vertically, the operation time is shortened, and the problem of loss caused by collision of the roller with other objects due to inaccurate positioning is solved.
In this embodiment, the roll lifting device further includes a PLC controller (not shown in the figure), the PLC controller is connected to the first inductive switch 61, the second inductive switch 62, the first alarm 51 and the second alarm 52, and the PLC controller receives a signal sent by the first inductive switch 61 or the second inductive switch 62 and controls the first alarm 51 or the second alarm 52 to alarm. The first inductive switch 61 senses the first iron block 21 and sends a signal to the PLC controller, and the PLC controller receives the signal and then controls the first alarm 51 to give an alarm. When the second inductive switch 62 induces the second iron block 22, a signal is sent to the same PLC controller, and the PLC controller receives the signal and then controls the second alarm to alarm. The intelligent control of the bridge crane is realized through the PLC, so that the operation of operators is facilitated, and the operation efficiency is improved.
In this embodiment, the number of the grinding machines is plural, and the plurality of grinding machines are arranged in the transverse direction, and the connection line of the centers of the plurality of grinding machines is not parallel to the transverse direction, and corresponds to the second iron blocks 22 at different positions. When a plurality of grinding machines are installed in a factory building, due to errors of installation and other factors, the longitudinal positions of the grinding machines are usually not consistent, so that the longitudinal positions of the rollers are different, the longitudinal positions of different grinding machines can be corresponded by different second iron blocks 22, and different iron blocks can be sensed by the second sensing switch 62 so that an operator can adjust the longitudinal position of the trolley 40 in place.
Further, the second inductive switches 62 are plural and correspond to the second iron blocks 22 one to one. Different second iron blocks 22 are sensed through different second sensing switches 62, the probability of misoperation is reduced, and the problem that the same sensing switch senses that the second iron blocks 22 send signals every time to cause judgment errors of operators is avoided. It should be understood that the first inductive switch 61 corresponds to a plurality of first iron blocks 21, which is based on the larger distance between the first iron blocks 21, so that whether the cart 30 reaches the set position can be distinguished by the simple judgment of the operator. The distance between the second iron blocks 22 is usually small, and it is not easy to directly distinguish whether the trolley 40 reaches the set position through the visual observation of the operator, so the accuracy of the arrangement of the plurality of second inductive switches 62 is higher, and the misoperation is not easy to occur.
Further, when different second inductive switches 62 sense the corresponding second iron blocks 22, the alarm signals sent by the second alarm 52 are different. Since the plurality of second inductive switches 62 are all connected to the same second alarm 52, the alarm signals sent by the second alarm 52 are different, so that the alarm signals can be distinguished by the operator.
In this embodiment, the first inductive switch 61 and the second inductive switch 62 are both infrared sensors. The infrared sensor has the advantages of long detection distance, wide application range, strong anti-interference capability and stable working performance, and is relatively good in rotation. Of course, the first inductive switch 61 and the second inductive switch 62 may also adopt other inductive devices, such as a grating sensor, a microwave inductive switch, an electromagnetic inductive switch, and the like, which is not limited in this application.
Further, the first alarm 51 is a buzzer or an alarm lamp. The buzzer sends out sound alarm after receiving the signal, and the alarm lamp gives an alarm by sending out light and can be used for reminding an operator. Similarly, the second alarm 52 may also be a buzzer or an alarm lamp.
In this embodiment, the second alarm 52 may be designed to emit different sounds to prompt the operator about the longitudinal position of the cart 40 when a buzzer is used, and the second alarm 52 may be designed to flash lights of different colors to prompt the operator about the longitudinal position of the cart 40 when an alarm lamp is used.
In this embodiment, the bridge crane is many, many the bridge crane can the simultaneous operation to in quick carry each roll to the grinding machine that corresponds on, improve production efficiency. For example, a first bridge crane needs to hoist a roller to a grinding machine at a far position, a second bridge crane needs to hoist the roller to a grinding machine at a near position, after the cart 30 of the first bridge crane runs for a certain distance, the cart 30 of the second bridge crane starts to run, when the first inductive switch 61 on the cart 30 of the first bridge crane senses the first iron block 21 at a near position, the first alarm 51 gives an alarm to prompt an operator of the position of the first cart 30 at the moment, the first bridge crane is not stopped until the carts 30 of the first bridge crane and the second bridge crane reach the set transverse position.
Further, a distance sensor and an anti-collision alarm which are connected with each other are arranged on the bridge cranes, and when the distance sensor senses that the distance between two adjacent bridge cranes is smaller than a set value, the anti-collision alarm gives an alarm. The problem of collision when two bridge cranes run simultaneously is prevented by arranging the distance sensor and the anti-collision alarm, and the safety is improved.
