Description

Technical Field

[0001] This utility model relates to the field of automated conveying technology for heavy materials, and in particular to a billet conveying and lifting structure. Background Technology

[0002] In the fields of metallurgy, casting and heavy machinery manufacturing, billets are a common semi-finished product that needs to be transferred and transported between different workstations. Currently, billet transport is mostly carried out by roller conveyor or crane lifting. For specific process steps that require precise lifting and horizontal transfer, such as heat treatment, testing or slow cooling, these methods have problems such as poor flexibility, low positioning accuracy and low degree of automation.

[0003] To meet the needs of automated conveying, existing technologies have developed conveying structures that combine horizontal movement and vertical lifting functions. These structures typically include tracks, moving frames, lifting drive mechanisms, and carriers or hooks for carrying billets. The lifting drive mechanisms often use motors in conjunction with gear racks or hydraulic cylinders to achieve lifting or hoisting actions.

[0004] However, in practical applications, it has been found that such conveying structures still have several technical defects that need to be addressed: when the billet is hoisted or placed on the support hook of the conveying mechanism, a huge instantaneous impact load is generated. This impact can easily damage the support hook and its connecting structure, shorten the service life of the equipment, and may also cause the billet to bounce or shift, posing a safety hazard. In addition, during horizontal transfer, due to factors such as uneven track and motor start-stop vibration, the billet will continuously vibrate up and down, affecting the stability of the conveying. For billets with high surface quality requirements, this vibration may cause surface scratches. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that billet is easily damaged, displaced, or has its surface quality damaged during automated conveying and lifting of billets in the prior art due to impact, vibration, and uneven force distribution at multiple support points. Therefore, a billet conveying and lifting structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A billet conveying and lifting structure includes two symmetrically arranged upper frames, a conveying plate is provided between the two upper frames, and the two ends of the conveying plate are respectively connected to the upper frames through horizontal guide components. The conveyor plate is equipped with a lifting mechanism, which includes a drive part and a guide part. The guide part is connected to a steel hook for supporting the billet. An elastic limiting element is provided between the steel hook and the guide portion.

[0007] In some embodiments, the elastic limiting member includes a limiting block disposed at the top of the steel hook and a limiting groove formed at the bottom of the connecting plate. A lifting block is provided inside the limiting groove. An upper spring and a lower spring are respectively provided on the upper and lower surfaces of the lifting block. The top of the limiting block passes through the bottom of the limiting groove and is fixedly connected to the lifting block.

[0008] In some embodiments, an elastic protective cover for protection is provided between the connecting plate and the limiting block.

[0009] In some embodiments, the limiting blocks of the plurality of steel hooks are connected by the same connecting shaft.

[0010] In some embodiments, the connecting shaft passes through through holes in multiple limiting blocks in sequence, and both ends of the connecting shaft are fixed by washers and nuts.

[0011] In some embodiments, the horizontal guide assembly includes a guide rail and a drive frame fixedly connected to the upper surface of the upper frame. The drive frame is provided with a drive wheel driven by a horizontal motor, and the drive wheel rolls in cooperation with the guide rail.

[0012] In some embodiments, the driving unit includes a drive motor, the transmission end of which is connected to a drive shaft, and the drive shaft is provided with a transmission gear.

[0013] In some embodiments, the guide portion includes a connecting plate and a limiting plate fixed to the upper surface of the conveyor plate, wherein the limiting plate has a guide groove inside.

[0014] In some embodiments, the connecting plate is provided with a lifting plate on the side near the drive shaft, and the lifting plate is connected to the drive gear by a rack on one side thereon; The connecting plate has an extension extending into the guide groove on the side near the limiting plate, and the end of the extension has a pulley that slides in cooperation with the inner wall of the guide groove.

[0015] Compared with the prior art, the present invention provides a billet conveying and lifting structure, which has the following beneficial effects.

[0016] 1. This utility model, by setting an elastic limiting component between the steel hook and the connecting plate, utilizes the coordinated extension and contraction of the upper and lower springs to efficiently absorb the impact kinetic energy generated when the billet is placed and convert it into elastic potential energy for dissipation, thereby reducing the peak impact force, protecting the equipment structure, and effectively suppressing the up-and-down swaying of the billet caused by uneven track and vibration during horizontal transfer, ensuring the stability of the conveying process.

[0017] 2. This utility model rigidly connects multiple independent steel hooks into a whole through a connecting shaft, forcing all support points to remain at the same height. This ensures that the long square billet is always in a horizontal state during placement and transportation, avoiding problems such as billet bending, tilting or excessive local stress caused by inconsistent heights of support points, thus improving the safety of transportation and product quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1 to 6 A billet conveying and lifting structure includes two symmetrically arranged upper frames 1, with a conveying plate 2 between the two upper frames 1; the two ends of the conveying plate 2 are respectively connected to the upper frames 1 through horizontal guide components 3.

[0032] The upper surface of the conveyor plate 2 is provided with a lifting mechanism 4; specifically, the lifting mechanism 4 includes a drive part 401 and a guide part 403. The drive part 401 is used to drive the steel hook 404 to rise and fall, and the guide part 403 provides a limit for the rise and fall of the steel hook 404; the horizontal guide assembly 3 is used to drive the conveyor plate 2, the lifting mechanism 4 and the steel hook 404 to move horizontally; the guide part 403 is connected to the steel hook 404, and the steel hook 404 is used to support the billet.

[0033] The horizontal guide assembly 3 includes a guide rail 304 and a drive frame 301 fixedly connected to the upper surface of the upper frame 1; the drive frame 301 is provided with a drive wheel 302 that corresponds to and cooperates with the guide rail 304, and the drive wheel 302 is driven by a horizontal motor 303 to move horizontally along the guide rail 304.

[0034] The drive unit 401 includes a drive motor 4011, the drive end of which is connected to a drive shaft 4012, and a drive gear 4013 is provided on the drive shaft 4012; a lifting plate 4032 is provided on the side of the connecting plate 4041 near the drive shaft 4012, and a rack is provided on the side of the lifting plate 4032 corresponding to the drive gear 4013, and the lifting plate 4032 is meshed with the drive gear 4013 through the rack; an extension 4033 is provided on the side of the connecting plate 4041 near the limiting plate 4035, and a pulley 4034 is provided at one end of the extension 4033 located in the guide groove 4036, and the pulley 4034 is slidably limited and engaged with the inner wall of the guide groove 4036.

[0035] The guide section 403 includes a connecting plate 4041 and a limiting plate 4035 disposed on the upper surface of the conveyor plate 2. The limiting plate 4035 has a guide groove 4036 inside. The steel hook 404 is connected to the connecting plate 4041.

[0036] In use, the horizontal motor 303 in the horizontal guide assembly 3 is started, and the horizontal motor 303 drives the drive wheel 302 to rotate. Then, it moves to one end of the upper frame 1 through the drive frame 301, the conveyor plate 2 and the steel hook 404. The steel hook 404 is controlled to move downward by the drive part 401 of the lifting mechanism 4. At this time, the billet is loaded onto one end of the upper frame 1. Then, the drive part 401 of the lifting mechanism 4 controls the steel hook 404 to move upward, so that the billet is kept at a specified height. Then, the horizontal motor 303 in the horizontal guide assembly 3 drives the steel hook 404 and the billet to move to the other end of the upper frame 1 to complete the transfer of the billet.

[0037] Please refer to further information. Figures 7 to 10 As shown, this embodiment is a further improvement on the above embodiment and is an optional technical solution.

[0038] The steel hook 404 is elastically limited to the connecting plate 4041, and an elastic limiting element 6 is provided between the steel hook 404 and the connecting plate 4041. As an example of the elastic limiting member 6, the elastic limiting member 6 includes a limiting block 601 disposed on the top of the steel hook 404 and a limiting groove 602 opened at the bottom of the connecting plate 4041. The limiting groove 602 is provided with a lifting block 6021 inside. The upper surface and the lower surface of the lifting block 6021 are respectively provided with an upper spring 6022 and a lower spring 6023. The lifting block 6021 is fixedly connected to the upper surface and the lower surface of the limiting groove 602 through the upper spring 6022 and the lower spring 6023 respectively. The top of the limiting block 601 is provided with a connecting post 6011. The top of the connecting post 6011 vertically penetrates the bottom of the limiting groove 602 and is fixedly connected to the lifting block 6021. The through hole at the bottom of the limiting groove 602 provides limiting guidance for the up and down movement of the connecting post 6011.

[0039] Furthermore, an elastic protective cover 6024 is provided between the connecting plate 4041 and the limiting block 601. The elastic protective cover 6024 is used to provide protection for the connecting column 6011 and the limiting groove 602.

[0040] In this embodiment, multiple steel hooks 404 support the billet. The impact force when the billet is placed is transmitted to the connecting column 6011 through the limiting block 601, which in turn pushes the lifting block 6021 to move downward within the limiting groove 602. At this time, the upper spring 6022 is stretched and the lower spring 6023 is compressed. Together, they form an elastic damping force, converting the kinetic energy of the billet into the elastic potential energy of the spring, realizing the absorption and dissipation of impact energy, and reducing the peak impact force at the moment of contact between the billet and the steel hook 404. At the same time, during the horizontal transfer of the billet, if the billet vibrates up and down due to factors such as equipment operation vibration and unevenness of the guide rail 304, the effect of gravity is weakened when the billet vibrates up and down. The elasticity of the upper spring 6022 and the lower spring 6023 pushes the lifting block 6021 to reset. Through the synergistic effect of the upper and lower springs, a dynamic elastic support is formed, which effectively suppresses and balances the vibration amplitude of the billet and maintains the stability of the billet during the transfer process.

[0041] like Figure 7 and Figure 8 As shown, as a further improvement of the above embodiment, a connecting shaft 7 can be provided between multiple steel hooks 404. The connecting shaft 7 is used to keep the steel hooks 404 at the same height, so as to prevent the billet from tilting or being subjected to uneven force due to inconsistent support height.

[0042] The connecting shaft 7 can be individually and fixedly installed between the two limit blocks 601, such as by welding or threading. Alternatively, a through hole is provided on the limiting block 601 for the connecting shaft 7 to pass through. One end of the connecting shaft 7 passes through multiple through holes on the limiting block 601 in sequence. Both ends of the connecting shaft 7 are provided with external threads. After the connecting shaft 7 passes through the through hole, both ends are installed and fixed by washers and nuts.

[0043] In use, the connecting shaft 7 rigidly connects multiple steel hooks 404 through the limiting block 601, enabling each steel hook 404 to respond synchronously to the drive command of the lifting mechanism 4. Simultaneously, it works in conjunction with the elastic limiting element 6 to achieve buffering, vibration reduction, and force balance, further improving the stability and reliability of the billet conveying. When impacts and vibrations occur during billet placement or transfer, the load on a single steel hook 404 is quickly distributed to other steel hooks 404 via the connecting shaft 7, causing the upper spring 6022 and lower spring 6023 of the multiple elastic limiting elements 6 to extend and retract in tandem. If a localized impact occurs on a steel hook 404, the spring corresponding to that hook 404 compresses to generate an elastic restoring force. Simultaneously, the connecting shaft 7 drives the upper spring 6022 and lower spring 6023 of adjacent steel hooks 404 to synchronously generate auxiliary buffering force, forming multi-point synergistic buffering and improving buffering efficiency.
