Description

Technical Field

[0001] The utility model relates to the field of winch structures, in particular to a winch for a blowing furnace spray gun. Background Art

[0002] In existing industrial production processes, particularly in converting furnaces in the metallurgical industry, precise positioning of the spray gun is crucial for ensuring product quality and production efficiency. Conventional converting furnace spray guns typically use a motor with a brake connected to a reducer, which in turn drives a wire rope drum to control the position of the spray gun. However, this structure has certain drawbacks.

[0003] First, because the encoder is mounted at the end of the wire rope drum, when the spray gun needs to stop, the encoder must transmit a signal to the programmable logic controller (PLC) through the input module. The PLC then outputs a braking signal to the motor with the brake. This multi-step signal transmission process results in a prolonged response time. Furthermore, the reduction ratio of the reducer can lead to inaccurate spray gun positioning, compromising operational precision.

[0004] Secondly, because the spray gun safely stops at any position thanks to the braking action of the brake motor, if the brake motor fails, there is no guarantee that the spray gun can be safely stopped at any position for maintenance. This not only increases the difficulty of replacing the motor, but also leads to extended downtime and increased maintenance costs during production. Utility Model Content

[0005] The purpose of the utility model is to provide a winch for a blowing furnace spray gun, which can improve the positioning accuracy of the spray gun and solve the problem of inaccurate positioning of the spray gun. At the same time, after the spray gun is parked at any position, the motor can be replaced separately, thereby improving maintenance efficiency and thus improving the stability and economy of the entire production process.

[0006] The above-mentioned optimized structure of the present utility model is achieved through the following technical solutions: a winch for a blowing furnace spray gun, comprising a base, a motor is provided on the base, the motor is connected to a reducer, the reducer is connected to a wire rope drum, a wire rope is wound around the wire rope drum, the end of the wire rope is connected to a spray gun, a brake is connected between the motor and the reducer, the motor is connected to an encoder, and the encoder, the motor and the brake are all connected to a programmable logic controller.

[0007] In some embodiments, the base includes a first long longitudinal plate and a second long longitudinal plate symmetrically arranged, two first long horizontal plates symmetrically arranged between the first long longitudinal plate and the second long longitudinal plate, and a short longitudinal plate is also arranged between the two first long horizontal plates, the reducer is arranged on the top of the first long longitudinal plate and the short longitudinal plate, and a support block is provided on the second long longitudinal plate, one side of the wire rope drum is fixed on the reducer, and the other side is rotatably connected to the support block.

[0008] In some embodiments, a second long horizontal board is connected between the short vertical board and the second long vertical board, and two short horizontal boards are provided between the short vertical board and the first long vertical board.

[0009] In some embodiments, the support block includes a support portion fixed on the second long longitudinal plate, the support portion is provided with a receiving ring, and the other side of the wire rope drum is coaxially provided in the receiving ring.

[0010] In some embodiments, a bearing is provided between the receiving ring and the other side of the wire rope drum.

[0011] In some embodiments, the support portion is a triangular plate, and two reinforcing plates are provided on the side of the support portion away from the wire rope drum, and the reinforcing plates are provided between the receiving ring and the second long longitudinal plate.

[0012] In some embodiments, the motor is a motor with a brake, and the brake is an electro-hydraulic brake.

[0013] In some embodiments, universal wheels are provided at the four corners of the base.

[0014] In some embodiments, a height limiter is provided on the side of the wire rope drum away from the reducer.

[0015] In summary, the present invention has the following beneficial effects:

[0016] This type of blowing furnace spray gun uses a winch to connect the encoder and the motor, which reduces the signal transmission links and shortens the response time. At the same time, it eliminates the influence of the speed reducer's reduction ratio on the spray gun position accuracy, and can achieve faster and more accurate spray gun positioning, thereby improving the positioning accuracy of the spray gun and solving the problem of inaccurate spray gun positioning. At the same time, the brake allows the spray gun to be safely stopped at any position when the motor fails, and the motor can be replaced separately, which facilitates maintenance, improves maintenance efficiency, reduces downtime, and thus improves the stability and economy of the entire production process.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] refer to Figure 1-3 A winch for a blowing furnace spray gun comprises a base 1, the base 1 comprising a first long longitudinal plate 11 and a second long longitudinal plate 12 symmetrically arranged, two first long horizontal plates 13 symmetrically arranged between the first long longitudinal plate 11 and the second long longitudinal plate 12, a short longitudinal plate 14 is further arranged between the two first long horizontal plates 13, the short longitudinal plate 14 divides the area between the first long longitudinal plate 11 and the second long longitudinal plate 12 into two areas, a reducer 3 is provided on the top of the first long longitudinal plate 11 and the short longitudinal plate 14, a support block 15 is provided on the second long longitudinal plate 12, one side of the wire rope drum 4 is fixed on the reducer 3, and the other side is rotatably connected to the support block 15. A second long horizontal plate 16 is connected between the short longitudinal plate 14 and the second long longitudinal plate 12, and two short horizontal plates 17 are provided between the short longitudinal plate 14 and the first long longitudinal plate 11, which can strengthen the connection strength inside the base 1. The first long longitudinal plate 11, the second long longitudinal plate 12, the first long horizontal plate 13, the short longitudinal plate 14, the second long horizontal plate 16 and the short horizontal plate 17 can all be grooved plates. The grooved plates have stronger bending strength and can further improve the strength of the base 1.

[0023] The support block 15 includes a support portion fixed to the second long longitudinal plate 12, with a receiving ring provided on the support portion. A wire rope drum 4 is positioned between the reducer 3 and the receiving ring. A wire rope is wound around the drum 4, and a spray gun is connected to the end of the wire rope. One side of the drum 4 is connected to the output shaft of the reducer 3, while the other side is fitted with a receiving ring. A bearing is provided between the receiving ring and the other side of the drum 4 to reduce friction and improve the smoothness of the drum 4's rotation. The support portion can be a triangular plate with a smaller upper portion and a larger lower portion to enhance support stability. Two reinforcing plates are provided on the side of the support portion away from the drum 4. These reinforcing plates are positioned between the receiving ring and the mounting plate 13 to provide additional support and stability.

[0024] The reducer 3 is connected to the motor 2, which drives the wire rope drum 4 to rotate through the reducer 3, thereby releasing or retracting the wire rope, and then moving the spray gun; the motor 2 can be a motor with a brake, which can accurately stop the movement of the spray gun at any position.

[0025] A brake 5 is connected between the motor 2 and the reducer 3. This brake 5 can be an electro-hydraulic brake, providing reliable braking force to ensure the spray gun can quickly and safely stop in an emergency, improving operational safety and reliability. It can also be combined with a motor with a brake to achieve dual braking, enhancing the spray gun's braking effect.

[0026] The motor 2 is connected to an encoder, and the encoder, motor 2 and brake 5 are all connected to a programmable logic controller (PLC), which can reduce the signal transmission links and shorten the response time. At the same time, it eliminates the influence of the reduction ratio of the reducer 3 on the position accuracy of the spray gun, and can achieve faster and more accurate spray gun positioning, thereby improving the positioning accuracy of the spray gun.

[0027] In some embodiments, universal wheels are provided at the four corners of the base 1 to facilitate the movement and positioning of the winch, so that the winch can be flexibly moved to a suitable working position, thereby improving the mobility and flexibility of the winch and enabling the equipment to adapt to different working environments.

[0028] In some embodiments, a height limiter 6 is provided on the side of the wire rope drum 4 away from the reducer 3, which can limit the height of the wire rope lifting and play a role in safety protection.

[0029] The specific working principle is as follows:

[0030] When the spray gun needs to be moved, the programmable logic controller sends a start signal to motor 2, which begins rotating and transmits power to the wire rope drum 4 via reducer 3. The wire rope is retracted or retracted as the drum 4 rotates, adjusting the spray gun's position. When the spray gun reaches the desired position, an encoder detects the rotational position of motor 2 and feeds this information back to the programmable logic controller. The controller then sends a braking signal to brake 5 and motor 2, causing motor 2 to stop. Simultaneously, brake 5 quickly responds and brakes motor 2, bringing the spray gun to a precise stop at the desired position.

[0031] When the motor needs to be replaced, due to the presence of the brake 5, the spray gun can still be accurately stopped at the required position after the motor with the brake is removed. At this time, it is only necessary to release the lock of the brake 5 after replacing the motor 2 and continue to operate the winch, avoiding the need to readjust the spray gun after the motor 2 is replaced, thereby improving work efficiency.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
