Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-speed wire rolling production, in particular to an anti-reverse device for an air-cooled roller table. Background Technique
[0002] The air-cooled roller table is an important device in the rear area of high-speed wire rolling, which is used to convey the wire rods spit out by the wire laying head to the coiling drum for coiling, and at the same time, different cooling is realized according to the requirements of different steel grades. The length of the air-cooled roller table is 118 meters, which is divided into 12 sections in total. The whole air-cooled roller table is arranged in a slope, with an angle of 10 degrees with the horizontal line. There is a step with a height of 200 mm at the junction of sections. Each section of the roller table is composed of an unequal number of rollers. The rollers are connected by sprockets and chains. The motor reducer drives one roller in the middle of the roller table, and the power is output to other rollers on this section of the roller table through sprockets and chains to realize the operation together.
[0003] The wire rods spit out by the wire laying head are arranged in a lap-by-lap manner on the air-cooled roller table. When a certain section of the air-cooled roller table fails or the equipment behind the roller table fails, the roller table needs to be stopped. After the roller table stops running, due to the slope of the roller table itself and the fact that the motor reducer itself does not have a braking and clamping function, the wire rods on the roller table will drive the rollers to reverse backward under the action of gravity. When it retreats to the step at the junction of sections, it stops retreating. During the retreat process, the wire rods will intersect with each other, resulting in that when the roller table resumes operation and conveys the wire rods to the coiling drum, the wire rods cannot enter the coiling drum normally due to the intersection, and it is necessary to manually separate the wire rods step by step, thus affecting the production rhythm. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an anti-reverse device for an air-cooled roller table aiming at the above deficiencies of the prior art, which can prevent the wire rods from driving the rollers to reverse under the action of gravity, avoid the intersection of wire rods, improve the production efficiency, and has the characteristics of wide application range and strong practicability.
[0005] The technical scheme adopted by the utility model is: an anti-reverse device for an air-cooled roller table, which includes a ratchet wheel. The ratchet wheel is installed on the output shaft of the motor reducer. A fixed seat is arranged on the motor reducer. A braking member for braking the ratchet wheel is rotatably connected to the fixed seat. The braking member includes a rotating shaft, a rotating rod and a claw. The rotating shaft is rotatably connected to the fixed seat. One side of the rotating shaft close to the ratchet wheel is connected to the claw, and the other side of the rotating shaft far from the ratchet wheel is connected to the rotating rod. The claw is clamped on the teeth of the ratchet wheel. A support seat is arranged on one side of the motor reducer. A locking device for locking the rotating rod is arranged above the rotating rod, and a counting device is arranged below the rotating rod. Both the locking device and the counting device are installed on the support seat.
[0006] As a further improvement, the locking device includes an electromagnet and an iron block, the iron block is installed above the rotating rod, and the electromagnet is arranged on a support seat above the iron block.
[0007] Furthermore, the counting device includes a push-type counter, a support plate and a controller. The support plate and the controller are mounted on a support base. The push-type counter is mounted on the support plate below the rotating rod. The push-type counter is electrically connected to the controller.
[0008] Furthermore, a display screen is hinged on the top of the support base, and the display screen is electrically connected to the controller.
[0009] Furthermore, a connecting plate is provided at the bottom of the support seat, and a plurality of connecting holes are opened on the connecting plate.
[0010] Furthermore, the rotating shaft, the rotating rod and the claw are an integrated structure.
[0011] Beneficial Effects
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] The utility model discloses an air-cooled roller table back-stop device, by adding a ratchet wheel on the output shaft of the motor reducer, and using it in conjunction with the brake claw, the roller table can operate normally during normal production. When the roller table stops operating, the claw quickly holds the ratchet wheel to realize the self-locking of the motor reducer, and prevents the wire rod from driving the roller to reverse under the action of gravity, effectively preventing the wire rod from retreating due to gravity, avoiding the wire rod from staggering, reducing the occurrence of faults, and improving production efficiency. When the claw is rotated upward under the action of the ratchet wheel, the rotating rod is rotated downward, thereby squeezing the push-type counter. Through the counting of the push-type counter, the controller can calculate how many times the ratchet has rotated, and the length of the wire rod conveyed can be calculated by the number of turns of the ratchet, which is then displayed in real time on the display screen to facilitate the staff to control the conveying length. When it is necessary to stop the machine, the claw is stuck on the ratchet under the action of gravity. At this time, the electromagnet is energized to generate magnetic force, which absorbs the iron block, thereby effectively preventing the claw from moving and improving the self-locking ability between the ratchet and the claw, thereby effectively avoiding the loosening of the claw and causing self-locking failure. It is easy to use and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

When the claw 21 is rotated upward under the action of the ratchet 1, the rotating rod 23 is rotated downward, thereby squeezing the push-type counter 41. The number of turns of the ratchet 1 can be calculated through the counting of the push-type counter 41, and the number of turns of the ratchet 1 can be calculated through the processing of the controller 43. The length of the wire rod conveyed can be calculated by the number of turns of the ratchet 1, and then displayed in real time through the display screen 10, so as to facilitate the staff to control the conveying length. When it is necessary to stop the machine, the claw 21 is stuck on the ratchet 1 under the action of gravity. At this time, the electromagnet 31 is energized to generate magnetic force, which absorbs the iron block 32, thereby effectively preventing the claw 21 from rotating, improving the self-locking ability between the ratchet 1 and the claw 21, thereby effectively avoiding the loosening of the claw 21 and causing self-locking failure.

When the machine needs to be stopped, the claw 21 is stuck on the ratchet 1 under the action of gravity.
