Description

TECHNICAL FIELD

[0001] The present application relates to the field of cranes, in particular to a billet conveying device. BACKGROUND

[0002] As a core intermediate product in the steel metallurgical industry, billets are widely used in the production and processing of downstream products such as pipes, profiles, and forgings. The efficiency, stability, and safety of the conveying link directly affect the production capacity and product quality of the entire steel production chain.

[0003] In the billet production process, from the billet discharge of the continuous casting machine to the subsequent slow cooling, heating, rolling, or finishing process, the conveying of the billets needs to be realized. Currently, the mainstream billet conveying method in the industry is mainly ground roller conveying. This type of equipment drives the billets to translate through the coordinated rotation of multiple groups of driving rollers, and has the characteristics of simple structure and strong carrying capacity. However, with the expansion of steel enterprise production capacity and the upgrading of intelligentization, the inherent defects of ground roller conveying are increasingly prominent: first, the equipment occupies a large amount of floor space in the production area, resulting in a compact layout, which limits the installation and maintenance space of other auxiliary equipment, especially in multi-process linked production lines, which is prone to form a conveying bottleneck; second, the contact between the billet and the roller is hard friction, which not only easily causes scratches on the bottom surface of the billet, affecting the appearance quality of the product, but also exacerbates the wear of the roller, increasing the equipment maintenance cost and downtime; third, for high-temperature billets (the temperature after continuous casting is usually 600-1000℃), the heat is lost quickly during ground conveying, and more energy needs to be consumed in the subsequent heating process, which does not conform to the industry development trend of energy saving and consumption reduction.

[0004] In addition, there are also ways to convey billets through a crane. The structure of such a crane is the same as the crane in the anti-collision device of the portal crane disclosed in publication CN221759369U. In order to ensure the stability during the operation of the crane, a hydraulic and spring system is provided in the above-mentioned application to prevent collision, which has certain positive significance. However, due to the large weight of the hoisted billet, slight sliding inevitably occurs between the crane roller and the track when the crane stops or starts, and the structure of the above-mentioned application cannot avoid the sliding friction caused by inertia through the hydraulic or spring structure, thereby affecting the stability and accuracy during the transportation of the billet.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0020] like Figures 1-10 As shown, the billet conveying equipment includes: The movable crossbeam 1 is slidably positioned between the two main beams 2, and the movable crossbeam 1 is equipped with a hoisting assembly 4 for vertical movement. The movable seat 3 is connected to the end of the movable crossbeam 1. The movable seat 3 is equipped with a drive wheel 5. The outer peripheral wall of the drive wheel 5 is circumferentially interposed with a docking groove 50. A slide rail 6 is provided on the main beam 2. Multiple couplings 32 are elastically provided in the slide rail 6 and spaced apart along the direction of the main beam 2. The couplings 32 are provided with a safety pressure bar 30 for moving the movable seat 3 toward the main beam 2.

[0021] In the billet conveying equipment, the movable crossbeam 1 is slidably set between two main beams 2. This cross-type structure can effectively utilize the upper space of the factory building, avoid occupying the ground area, and solve the problem of the large space occupied by traditional ground roller conveyors, which leads to a compact production layout.

[0022] The hoisting assembly 4, which moves up and down on the movable crossbeam 1, can be adjusted up and down to hoist and lower the billet, so that the billet does not come into contact with the ground during the transportation process. This reduces the hard friction between the bottom of the billet and the ground, avoids surface scratches, and ensures the appearance quality of the product.

[0023] The movable seat 3 is connected to the end of the movable crossbeam 1. The drive wheel 5 provided by the drive wheel 5 provides power for the movement of the movable crossbeam 1. The circumferentially spaced mating grooves 50 on the outer circumferential wall of the drive wheel 5 cooperate with the multiple mating joints 32 elastically provided in the slide rail 6 on the main beam 2. When the drive wheel 5 rotates, each mating groove 50 on the drive wheel 5 is exactly mated with each mating joint 32 provided in the slide rail 6. That is, the mating joint 32 is located in the mating groove 50, thus avoiding the arc surface structure of the outer circumferential wall of the drive wheel 5 without mating groove 50 pressing against the mating groove 50. At this time, the drive wheel 5 is controlled by a motor or a motor reducer. At this time, the drive wheel 5 and the surface of the slide rail 6 are subject to rolling friction.

[0024] When the power on the drive wheel 5 is lost, the entire movable seat 3 will inevitably continue to move due to its large mass. However, at this time, the power on the drive wheel 5 is lost, and the drive wheel 5 locks up and cannot rotate. Therefore, at the moment of stopping, the inertia generated by the entire movable seat 3 will cause sliding friction between the locked drive wheel 5 and the slide rail 6. At this time, the mating groove 50 and the mating joint 32 will no longer strictly follow the one-to-one correspondence as before when rolling. Instead, the arc surface on the drive wheel 5 will press against the mating joint 32 during the slight sliding process, causing the mating joint 32 to sink into the interior of the slide rail 6.

[0025] When the connector 32 moves downward, the safety lever 30 connected to it moves downward synchronously. The end of the safety lever 30 away from the connector 32 will descend and press down on the moving seat 3, thereby further increasing the sliding friction between the moving seat 3 and the slide rail 6, thus limiting the abnormal inertial movement of the moving seat 3 relative to the slide rail 6.

[0026] This application, by setting up a docking groove 50, a connecting joint 32, and a safety pressure rod 30, and by cleverly utilizing the motion laws between the two objects in rolling friction and sliding friction, ensures that when the drive wheel 5 stops supplying power and locks up, the connecting joint 32 moves downward and simultaneously drives the safety pressure rod 30 downward, thereby increasing the friction between the moving seat 3 and the slide rail 6, thus preventing abnormal sliding between the slide rail 6 and the moving seat 3, further ensuring the stability during the vehicle's movement, and thus ensuring the accuracy of the billet's position during transportation.

[0027] In some further embodiments, the mating joint 32 is a raised triangular prism structure, and the mating groove 50 is adapted to the mating joint 32.

[0028] The connector 32 adopts a raised triangular prism structure, and the mating groove 50 is adapted to the connector 32. During the rotation of the drive wheel 5, the edge of the connector 32 can form a guiding effect with the inner wall of the mating groove 50, making the meshing of the mating groove 50 and the connector 32 more precise, reducing misalignment or offset during the meshing process, and improving the stability of power transmission between the drive wheel 5 and the slide rail 6. Compared with other shapes of mating structures such as cylinders, the triangular prism has stronger guiding properties and can more effectively ensure that the connector 32 minimizes contact between the connector 32 and the mating groove 50 during the mating process.

[0029] In some further embodiments, the path length between two adjacent mating slots 50 is the same as the path length between two adjacent mating joints 32.

[0030] The path length between two adjacent docking slots 50 is the same as the path length between two adjacent mating joints 32. This setting ensures that when the drive wheel 5 rotates, the docking slot 50 can continuously and orderly mesh with the mating joint 32, and there will be no meshing jamming or excessive gap due to mismatched spacing. This enables the smooth movement of the moving seat 3, ensures the smoothness of the billet conveying process, and further improves the accuracy of conveying.

[0031] In some further embodiments, the slide rail 6 is provided with a relief groove 61, and the bottom of the relief groove 61 is provided with a sliding hole 63; the slide rail 6 is provided with a slot channel 60, which communicates with the sliding hole 63; the lower end of the safety pressure rod 30 passes through the slot channel 60 and is connected to the sliding rod 33 connected to the bottom of the connector 32; a first spring 62 is sleeved on the sliding rod 33, the first spring 62 is located in the relief groove 61, one end of the first spring 62 abuts against the connector 32, and the other end abuts against the bottom of the relief groove 61.

[0032] The clearance groove 61 provided on the slide rail 6 provides space for the telescopic movement of the connector 32, while the sliding hole 63 is used to accommodate the sliding rod 33 connected to the bottom of the connector 32.

[0033] The slot channel 60 is connected to the sliding hole 63, so that the lower end of the safety lever 30 can pass through the slot channel 60 and connect with the sliding lever 33, ensuring that the safety lever 30 moves synchronously with the extension and retraction of the connector 32.

[0034] The first spring 62, sleeved on the sliding rod 33, is located in the relief groove 61. The two ends of the first spring 62 abut against the bottom of the mating joint 32 and the relief groove 61, respectively. When the non-mating groove 50 part of the outer peripheral wall of the drive wheel 5 presses against the mating joint 32, the mating joint 32 is pressed and drives the sliding rod 33 to move down. The safety pressure rod 30 is pressed down simultaneously, and the first spring 62 is compressed. When the drive wheel 5 starts to rotate, when the mating groove 50 and the mating joint 32 are re-mating, the first spring 62 resets and pushes the mating joint 32 to move up, thereby restoring the prerequisite triggering condition of the safety pressure rod 30 and preparing for the next step of sliding friction.

[0035] In some further embodiments, a sliding groove 31 is provided above the movable seat 3, a lowering rod 330 is provided at the top of the safety pressure rod 30, a pressure plate 34 is provided at the bottom of the lowering rod 330, the pressure plate 34 is slidably disposed in the sliding sleeve 35, a second spring 36 is provided at the bottom of the sliding sleeve 35, and the two ends of the second spring 36 abut against the pressure plate 34 and the bottom wall of the sliding sleeve 35 respectively; a roller 37 is provided at the bottom outer side of the sliding sleeve 35.

[0036] The groove 31 above the movable seat 3 provides guidance for the movement of the sliding sleeve 35. The lower pressure rod 330 at the top of the safety pressure rod 30 is slidably set in the sliding sleeve 35 through the pressure plate 34. The two ends of the second spring 36 on the bottom wall inside the sliding sleeve 35 abut against the pressure plate 34 and the bottom wall of the sliding sleeve 35 respectively, forming an elastic buffer structure.

[0037] When the safety lever 30 is pressed down, the lever and the pressure plate 34 are pressed down, and the second spring 36 is compressed. This prevents the safety lever 30 from mechanically pressing the moving seat 3 hard. Instead, the pressure on the moving seat 3 is slowly increased by the second spring 36 to increase the sliding friction between the two.

[0038] Multiple mating grooves 50, mating joints 32, and safety pressure rods 30 are provided along the length of the main beam 2. During the movement of the movable seat 3, the sliding groove 31 provided on it will always slide and cooperate with the roller 37 at the bottom of the sliding sleeve 35. However, it will only gradually press towards the slide rail 6 when sliding friction occurs between the movable seat 3 and the slide rail 6.

[0039] In some other embodiments, in order to ensure the stability of the safety lever 30, a stabilizing frame can be provided on the movable seat 3, and multiple stabilizing holes are provided on the stabilizing frame, with the safety lever 30 slidably disposed in the stabilizing holes.

[0040] In some further embodiments, the hoisting assembly 4 includes a sliding frame and a limiting wheel 470; the sliding frame is provided with a drive rack 40, and the moving crossbeam 1 is provided with a power gear 41, which is connected to the drive rack 40 in a transmission manner; the moving crossbeam 1 is provided with a limiting groove 471, and the limiting wheel 470 is rotatably disposed in the limiting groove 471.

[0041] The sliding frame in the hoisting assembly 4 is used to install hoisting-related structures. Its drive rack 40 is connected to the power gear 41 on the moving crossbeam 1. The rotation of the power gear 41 drives the drive rack 40 to move, thereby realizing the up and down movement of the sliding frame, thus adjusting the hoisting height to meet the hoisting requirements of billets of different specifications.

[0042] The limiting groove 471 on the moving crossbeam 1 cooperates with the limiting wheel 470 on the sliding frame. The limiting wheel 470 rolls in the limiting groove 471, which restricts the left and right deviation of the sliding frame during the up and down movement, ensures the straightness of the sliding frame movement, avoids the swaying during billet hoisting, improves the stability of hoisting, and reduces the collision damage to the billet caused by swaying.

[0043] In some further embodiments, a first helical gear 420 is provided on the first rotating shaft 42 of the power gear 41, a bracket 43 is provided on the moving crossbeam 1, a worm gear 44 is rotatably provided on the bracket 43, a second helical gear 430 is provided on the worm gear 44 that meshes with the first helical gear 420, a toothed plate 46 is provided on the sliding frame, and a worm wheel 45 is rotatably provided on the bracket 43 that meshes with the toothed plate 46.

[0044] The first helical gear 420 on the first rotating shaft 42 of the power gear 41 meshes with the second helical gear 430 on the worm gear 44 on the bracket, thereby changing the power direction and converting the horizontal power transmission into the vertical power transmission.

[0045] The toothed plate 46 on the sliding frame meshes with the worm wheel 45 on the bracket 43. The structure of the worm wheel 45 and worm 44 (worm 44 and worm wheel 45) has a self-locking characteristic. When the sliding frame moves the billet to a certain height, the worm wheel 45 will not rotate in the opposite direction due to the weight of the billet, thereby locking the position of the sliding frame, preventing the billet from falling accidentally, and improving the safety of the hoisting process. It is especially suitable for hoisting heavy-duty billets.

[0046] During the design process, the worm gear 45 and worm 44 should meet the self-locking condition; the worm gear 45 and worm 44 are mainly used to reduce the meshing force of the square billet between the power gear 41 and the drive rack 40.

[0047] When the first rotating shaft 42 rotates, the power gear 41 and the first helical gear 420 rotate synchronously.

[0048] In some further embodiments, the sliding frame is provided with a sliding column 48, and the mounting bracket 47 with the limiting groove 471 is provided with a sliding slot 482. The sliding column 48 is provided through the sliding slot 482, and a third spring 480 is sleeved on one end of the sliding column 48. An adjusting nut 481 is screwed on the end of the sliding column 48 that passes through the third spring 480.

[0049] The sliding column 48 on the sliding frame passes through the sliding slot 482 on the mounting frame 47, further restricting the swaying of the sliding frame in the left and right directions. It works in conjunction with the limit wheel 470 to form a double limit, ensuring that the sliding frame can only move in the vertical direction.

[0050] The sliding column 48 passes through the sliding slot 482 and is fitted with a third spring 480 and an adjusting nut 481. The preload of the third spring 480 can be changed by adjusting the position of the adjusting nut 481. When the sliding frame moves up and down, the meshing between the power gear 41 and the drive rack 40, and between the toothed plate 46 and the worm gear 45 will be tighter under the action of the third spring 480, so as to avoid shaking during the disassembly and assembly of the billet and affect the stability of the meshing.

[0051] In some further embodiments, the bottom of the sliding frame is provided with a hook 7, the bottom of the hook 7 is provided with a movable groove 76, the movable groove 76 is movably provided with a wedge block 70, the bottom of the wedge block 70 is provided with a guide post 72, the bottom of the movable groove 76 is provided with a guide sleeve 73, the guide post 72 is provided with a fourth spring 74, the two ends of the fourth spring 74 respectively abut against the bottom wall of the movable groove 76 and the bottom of the wedge block 70; the side of the wedge block 70 is provided with a first locking tooth 700, the movable groove 76 is provided with a rotating disk 75, the outer periphery of the rotating disk 75 is provided with a second locking tooth 750 at intervals, and the second locking tooth 750 is provided with a stop bar 751.

[0052] The hook 7 at the bottom of the sliding frame is used to hook the billet. The wedge block 70 in the movable groove 76 at the bottom of the hook 7 has a tendency to pop out under the action of the fourth spring 74. When the hook 7 hooks the billet, the wedge block 70 contacts the billet and is pressed back into the movable groove 76. Since the first locking tooth 700 on the side of the wedge block 70 meshes with the second locking tooth 750 of the rotating disk 75 in the movable groove 76, the rotating disk 75 rotates, thereby causing the stop bar 751 on the rotating disk 75 to rotate out of the movable groove 76, so as to "seal" the opening of the hook 7, that is, to prevent the billet from sliding and falling during the movement, thus improving the stability of the hoisting.

[0053] A countersunk groove can be provided on the upper edge of the sliding groove. A cover plate 71 is provided in the countersunk groove to restrict the wedge block 70 from directly popping out of the movable groove 76. At the same time, two openings are provided on the cover plate 71, one for accommodating the protruding wedge area in the wedge block 70, and the other for accommodating the stop bar 751.

[0054] In some further embodiments, the moving crossbeam 1 is provided with a drive motor 8 and a reduction gearbox 9, the first rotating shaft 42 is connected to the conveying end of the reduction gearbox 9, and the drive motor 8 is connected to the input end of the reduction gearbox 9.

[0055] The drive motor 8 on the moving crossbeam 1 provides power to the equipment. The gearbox 9 is connected to the input end of the drive motor 8, and the first rotating shaft 42 is connected to the output end of the gearbox 9. The output speed and torque can be adjusted through the gearbox 9 to adapt to different conveying speed requirements and the lifting power requirements of billets of different weights. The cooperation between the drive motor 8 and the gearbox 9 achieves stable power output and precise control, ensuring the smoothness of the vertical movement of the lifting assembly 4 and the movement of the moving crossbeam 1 along the main beam 2, thereby improving the controllability and applicability of the equipment.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
