Description

Technical Field

[0001] The utility model belongs to the field of metallurgical equipment and relates to the field of handling equipment, in particular to a short rod handling device. Background Art

[0002] During the production process of wear-resistant steel balls, raw steel rods are cut into short rods of standard lengths suitable for subsequent processing and forming. These short rods are then placed on a storage platform, where they roll down onto a feed platform and are subsequently fed into a high-temperature furnace for heating. As the short rods roll onto the feed platform, the height difference between the storage platform and the feed platform causes them to impact the feed rollers on the platform. Over time, the impact of these impacts can shorten the feed rollers' service life, causing significant wear and even damage. If necessary, the machine must be shut down for maintenance, which inevitably impacts the progress of steel ball processing. This impact is then transmitted to the main body of the feed platform, also impacting its overall lifespan. Utility Model Content

[0003] To address the technical problem of short rods rolling onto the feed platform and causing impact damage to the platform, the utility model provides a short rod handling device. By erecting a lifting bracket between the storage platform and the feed platform, the short rods are lifted using a sling, thus preventing the short rods from causing impact damage to the feed platform, ensuring smooth operation, and extending the service life of the feed platform.

[0004] The technical solution adopted by the utility model is: to provide a short rod handling device, including a storage platform and a feeding platform arranged in the front and back, the table top of the storage platform is inclined, and a feeding port and a taking port are provided on the storage platform, and the height of the feeding port is higher than the height of the taking port; a plurality of limit blocks are provided on the width direction of the taking port of the storage platform, and a plurality of lifting notches are provided on the taking port, and the lifting notches are arranged between the limit blocks; a lifting bracket is erected above the feeding platform, and the lifting bracket extends to above the taking port; a handling platform is provided on the top of the lifting bracket for reciprocating movement by means of a reciprocating linear drive component, a sling is provided for vertical lifting on the handling platform, and at least two hooks are provided on the sling, and the hooks respectively correspond to the positions of the lifting notches.

[0005] The cut short bars are placed on the storage platform from the feed port. The surface of the storage platform is tilted so that the short bars can roll down to the feeding port of the storage platform. Limit blocks are evenly distributed on the feeding port to prevent the short bars from falling off the storage platform, thereby ensuring safety in use. The feeding platform is set up on one side of the feeding port, and a lifting bracket is set up above the feeding platform. The lifting bracket extends above the feeding port. The transport platform that reciprocates on the top of the lifting bracket adjusts the position of the sling. After pushing the sling to above the feeding port, the sling is lowered so that the hook is located at the lifting notch of the storage platform, and the short bars are lifted by the lifting notch. The lifted short bars are transported above the feeding platform and lowered onto the feeding platform for transportation, thereby avoiding impact on the feeding platform, avoiding damage to the feeding platform, ensuring its safety, and extending its service life.

[0006] To further optimize the technical solution, the reciprocating linear drive assembly includes a hydraulic cylinder fixedly mounted on the top of the lifting bracket, and the output end of the hydraulic cylinder is fixedly mounted on the transport platform.

[0007] The transport platform is driven by a hydraulic cylinder, which has a simple structure, is safe and stable to use, and improves economical use.

[0008] To further optimize this technical solution, the transport platform includes a base fixedly mounted to the output end of the hydraulic cylinder, and the base is linearly assembled with the lifting bracket with the help of a guide assembly; a screw is rotatably mounted on the base with the help of a power assembly, the screw passes downward through the base and is threadedly connected to the sling, and two guide rods are arranged parallel to the circumference of the screw, and the guide rods are respectively fixedly mounted to the base and slidably mounted with the sling.

[0009] The output end of the hydraulic cylinder is fixedly installed on the base of the handling platform, and the spreader is assembled on the base with the help of a screw and a guide rod. The fixed installation of the guide rod and the base constrains the spreader, so that when the screw is driven to rotate, it engages with the spreader thread, driving the spreader to move vertically. When the hydraulic cylinder is running, the spreader is driven to move back and forth through the base to adjust the position of the spreader, and the short rod is lifted by the lifting of the spreader to be lifted from the feeding platform to the feeding platform. It is easy to operate, avoids impact damage to the feeding platform, and ensures safe operation.

[0010] To further optimize this technical solution, the guide assembly includes a matching slide rail and track wheel, the slide rail is laid parallel to the top of the lifting bracket, the track wheel is assembled with the base, and an anti-slip block is provided at the end of the slide rail away from the hydraulic cylinder.

[0011] The base moves with the help of slide rails and track wheel eye lifting brackets. Its structure is simple, which ensures the reliability of the base's straightness, reduces movement resistance, and reduces energy consumption. The anti-slip block set at the end of the slide rail prevents the base from slipping off the slide rail, ensuring safety in use.

[0012] To further optimize the technical solution, the power assembly includes a drive motor fixedly mounted on the base, and the output end of the drive motor is fixedly mounted coaxially with the screw.

[0013] The driving motor and the screw are coaxially installed to drive the screw to rotate. The structure is simple and the use is stable and reliable.

[0014] To further optimize the technical solution, the sling includes a crossbeam threadedly connected to the screw rod, the bottom surface of the crossbeam is fixedly installed with the hook, and the crossbeam is slidably connected to the guide rod.

[0015] The main body of the sling is a crossbeam, which is threadedly connected to the screw and slidably connected to the guide rod. The guide rod limits the lateral direction. As the screw is driven, it is threadedly connected to the crossbeam, allowing the crossbeam to rise and fall smoothly along the screw. Its structure is simple, reduces the failure rate, and ensures the stability and reliability of operation.

[0016] To further optimize the technical solution, the feeding platform includes a feeding rack mounted on one side of the material storage platform's material taking port, and feeding rollers are evenly mounted on the feeding rack, and the feeding rollers are rotatably mounted on the feeding rack with the aid of a driving member.

[0017] The feeding platform supports the feeding wheel with the help of the feeding frame, and the driving part drives the feeding wheel to rotate on the feeding frame. After the short rods are placed on the feeding wheel, the rotating feeding wheel transports the short rods to the heating furnace, which is stable to use.

[0018] To further optimize this technical solution, the feed roller includes a wheel body and a connecting shaft coaxially assembled with the wheel body, both ends of the connecting shaft pass through the wheel body and are rotatably mounted with the feed rack, and one end of the connecting shaft passes through the feed rack and is connected in series with the help of a transmission chain, and one of the connecting shafts is driven and mounted with the driving member.

[0019] The feed roller consists of a wheel body and a connecting shaft. Both ends of the connecting shaft protrude from the wheel body so that it can be assembled on the feed rack. One end of the connecting shaft passes through the feed rack and is connected in series with the help of a transmission chain. After the driving part is connected to the connecting shaft on one of the feed rollers, all the feed rollers are driven to run synchronously to transport short rods. It has a compact structure and stable operation.

[0020] To further optimize the technical solution, the driving member includes a power motor fixedly mounted on the feed rack, and the output end of the power motor is driven and mounted via a transmission belt and a connecting shaft.

[0021] The power motor is fixedly installed on the feed frame and drives the connecting shaft with the help of a transmission belt to make the feed roller rotate smoothly. It has a simple structure and is stable and reliable to use.

[0022] To further optimize the technical solution, an inner concave surface is provided on the outer side wall of the wheel body.

[0023] The short rods are placed on the inner concave surface of the wheel body and transported by the feeding roller. The inner concave surface prevents the short rods from detaching from the wheel body, ensuring the safety and reliability of the short rod transportation.

[0025] 1. The cut short bars are placed on the storage platform from the feeding port. The storage platform is tilted to facilitate the short bars to roll down to the feeding port and are supported by the limit blocks on the feeding port to prevent the short bars from rolling down from the storage platform, thus ensuring the reliability of the storage platform. A lifting notch is set on the feeding port to facilitate the lifting and transportation of the short bars, ensuring flexibility of use.

[0026] 2. A lifting bracket is installed on the feeding platform, which extends to the top of the feeding port of the storage platform. The base of the lifting bracket moves linearly along the slide rail with the help of track wheels, and reduces friction resistance, so that the hydraulic cylinder drives the base smoothly and stably, ensuring the linear drive effect. The base is equipped with a sling with the help of a screw and a guide rod. The guide rod is assembled with the sliding assembly of the sling to constrain it. After the screw is driven to rotate, it engages with the thread of the sling, making it rise and fall smoothly. The structure is simple and ensures reliability in use.

[0027] 3. The lifting device is mainly composed of a crossbeam, which is slidably connected to the guide rod to constrain the crossbeam. The screw is threadedly connected to the crossbeam. After the screw rotates, it engages the crossbeam and makes it rise and fall along the guide rod. The bottom of the crossbeam is equipped with a hook. The position and number of the hook match the lifting notch, so that the hook can lift the short bar through the lifting notch. The short bar can be lifted at multiple points to ensure lifting reliability and safety.

[0028] 4. The feeding roller is composed of a wheel body and a connecting shaft. Both ends of the connecting shaft pass through the wheel body respectively, which is convenient for assembling it on the feeding rack. One end of the connecting shaft passes through the feeding rack and is connected in series with the help of a transmission chain to reduce the power source while ensuring the synchronous operation of the feeding roller, making the structure more compact and ensuring the smoothness and reliability of short rod transportation.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Please see the attached Figure 1 , Attachment Figure 2 A short rod handling device comprises a storage platform 1 and a feeding platform 2 arranged in front and back. A feeding port and a discharging port are provided on the table of the storage platform 1. The cut short rods are placed on the table of the feeding platform 2 from the feeding port. The height of the feeding port on the feeding platform 2 is higher than that of the discharging port. The table is inclined so that the short rods roll down along the table toward the discharging port. Limiting blocks 101 are evenly distributed on the discharging port. The limiting blocks 101 prevent the short rods from falling from the storage platform 1. The feeding platform 2 is erected on one side of the discharging port of the storage platform 1. After the short rods on the storage platform 1 are transferred to the feeding platform 2, they are transported into the heating furnace.

[0037] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 5The feeding frame 201 of the feeding platform 2 is set up on one side of the feeding port, and the feeding support wheel 202 is evenly set up on the feeding frame 201. The feeding support wheel 202 includes a wheel body 2021 and a connecting shaft 2022 coaxially assembled with the wheel body 2021. Both ends of the connecting shaft 2022 pass through the wheel body 2021 and are rotatably installed with the feeding frame 201. One end of the connecting shaft 2022 passes through the feeding frame 201 and is connected in series with the transmission chain 2023. After assembling one of the connecting shafts 2022 with the driving member, the feeding is driven. The supporting wheel 202 rotates synchronously to ensure the conveying effect of the short rods. The driving part includes a power motor 203 fixedly installed with the feeding frame 201. The output end of the power motor 203 is driven and installed with the connecting shaft 2022 by means of a transmission belt 204. The structure is simple and ensures the transmission reliability. When the feeding wheel conveys the short rods, the outer wall of the wheel body 2021 is provided with an inner concave surface 20211. The short rods are placed in the inner concave surface 20211 to prevent the short rods from falling off the feeding supporting wheel 202, thereby ensuring the safety and reliability of the short rod transportation.

[0038] Please see the attached Figure 1-3 When the short stick is transferred from the storage platform 1 to the feeding platform 2, a lifting bracket 3 is set above the feeding slip, and the lifting bracket 3 extends above the feeding port of the storage platform 1. The top of the lifting bracket 3 is reciprocated by the reciprocating linear drive component. A transport platform 4 is set. The reciprocating linear drive component can choose a hydraulic cylinder 6. The output end of the hydraulic cylinder 6 is fixedly installed with the transport platform 4. The hydraulic cylinder 6 provides power for the linear reciprocating movement of the transport platform 4;

[0039] Please see the attached Figure 1-4 The transport platform 4 includes a base 401 fixedly mounted on the output end of the hydraulic cylinder 6. The base 401 is linearly assembled with the lifting bracket 3 by means of a guide assembly. The guide assembly is a matching slide rail 301 and a track wheel 4011. The slide rail 301 is laid parallel to the top of the lifting bracket 3. The track wheel 4011 is assembled with the base 401. The track wheel 4011 drives the base 401 to move linearly along the slide rail 301 to ensure the reliability of linear movement, reduce sliding resistance, and reduce energy consumption. An anti-slip block 3011 is provided at the end of the slide rail 301 away from the hydraulic cylinder 6 to prevent the base 401 from slipping off the slide rail 301, thereby ensuring safety in use.

[0040] Please see the attached Figure 1-4A screw 402 is rotatably mounted on the base 401 with the aid of a power assembly. The power assembly is a drive motor 404. The drive motor 404 is fixedly mounted on the base 401, and the output end of the drive motor 404 is fixedly mounted coaxially with the screw 402, thereby driving the screw 402 to rotate. The screw 402 penetrates the base 401 downward and is equipped with a sling 5. Two guide rods 403 are arranged parallel to the circumference of the screw 402. The two guide rods 403 are respectively fixedly mounted on the base 401 and slidably mounted with the sling 5. The guide rods 403 limit the sling 5. When the screw 402 is driven to rotate, the screw 402 engages with the thread of the sling 5, driving the sling 5 to rise and fall vertically in the lifting bracket 3.

[0041] Please see the attached Figure 4 The lifting device 5 includes a crossbeam 501 threadedly connected to the screw 402, and the crossbeam 501 is slidably connected to the guide rod 403, so that the crossbeam 501 is lifted and lowered along the screw 402. At least two hooks 502 are fixedly installed on the bottom surface of the crossbeam 501. When the lifting device 5 is used to lift the short rod on the material storage platform 1, the lifting device 5 is moved to the material taking port of the material storage platform 1, and the hooks 502 are lowered. A plurality of lifting notches 102 are provided on the material taking port of the material storage platform 1. The lifting notches 102 are arranged between the limit blocks 101, and the lifting notches 102 match the positions of the hooks 502, so that the hooks 502 can lift the short rod from the lifting notches 102, and there are at least two hooks 502 to ensure the safety of lifting. After the lifted short rod is lifted above the material feeding platform 2, the short rod is placed on the material feeding roller 202 to avoid impact damage to the material feeding roller 202.

[0042] The working principle of the short bar handling device is as follows: after the cut short bars are placed on the storage platform 1 from the feed port, the short bars roll down along the table to the material taking port and are stopped by the limit block 101 of the material taking port to prevent the short bars from rolling down from the storage platform 1, and then the hydraulic cylinder 6 is started, which pushes the base 401 to move along the slide rail 301 on the lifting bracket 3, and pushes the sling 5 to the top of the material taking port, and the driving motor 404 drives the screw 402 to rotate, and the screw 402 is threadedly connected to the crossbeam 501 of the sling 5, driving the crossbeam 501 to drive the hook 502 to descend, and the crossbeam 501 is slidably connected to the guide rod 403 arranged parallel to the side of the screw 402. The guide rod 403 limits the crossbeam 501, so that it and the screw 402 can be raised and lowered stably and smoothly. After it is on one side of the lifting gap 102 and is located under the short rod, the base 401 continues to push the hook 502 to the bottom of the short rod. As it moves upward horizontally, the hook 502 lifts the short rod. As the hydraulic cylinder 6 pulls back the base 401, the sling 5 transfers the short rod to the top of the feeding platform 2, so that the sling 5 lowers the short rod to the feeding roller 202, avoiding impact on the feeding roller 202, ensuring safety in use and extending its service life. The feeding roller 202 is connected in series with the help of a transmission chain 2023 so that the power motor 203 drives it to rotate synchronously, thereby conveying the short rod smoothly and stably, and an inner concave surface 20211 is provided on the outer side wall of the wheel body 2021 of the feeding roller 202, and the short rod is placed on the inner concave surface 20211 to prevent the short rod from falling off the feeding roller 202, thereby ensuring the safety of transportation.
