Abstract

This invention discloses a steel-moving device, a steel-moving machine, and a steel-moving method, belonging to the field of conveyor technology. It includes two end sprockets, a conveyor chain, a billet holder, and a steel-pushing mechanism. The two end sprockets drive the conveyor chain in cyclical motion. The conveyor chain, sleeved on the two end sprockets, drives the billet holder and the steel-pushing mechanism to move. The billet holder is mounted on the conveyor chain to support the billet. The steel-pushing mechanism is sleeved on the rear chain shaft of the billet holder. The pushing arm of the steel-pushing mechanism transmits the pushing force when upright and limits the angle when tilting. This invention breaks through the traditional stroke limitation by having the steel-pushing mechanism and the billet holder move with the conveyor chain to the end sprockets. The billet holder integrates the chain plate section function, and combined with a wheel-rail system, it achieves rail-free conveying. The wheel set transmits the load through the rail, avoiding chain load. The bidirectional limiting design of the steel-pushing mechanism enables cyclical operation of upright pushing and tilting billet movement. The structure is compact and suitable for the large-scale steel-moving needs of the metallurgical industry, reducing complexity and maintenance costs.

Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to a steel transfer device, steel transfer machine, and steel transfer method. Background Technology

[0002] Chain-type steel transfer machines typically employ a unidirectional tilting movable steel pusher head. These pushers come in two types: internal and external. Driven by a chain, the pusher head propels the steel billet along a slide rail that carries it to the next stage. Internal pusher heads, with a unidirectional tilting design and the chain positioned inside, can only slide back and forth within a straight line from the two end sprockets, resulting in a limited effective steel transfer range and low efficiency. External pusher heads, also with a unidirectional tilting design and the chain positioned outside, have the pusher head spanning the upper side of the chain plate. While this allows the pusher head to move to the end sprocket, a separate slide rail is still required to carry the steel billet, resulting in a larger space requirement.

[0003] For special working conditions with limited space, it is impossible to simultaneously move the steel head to the end sprocket and directly transport the steel billet without a slide rail. This invention proposes a new solution to the above problems. Summary of the Invention

[0004] To overcome at least one of the aforementioned drawbacks, this invention provides a steel-moving device, a steel-moving machine, and a steel-moving method. The objective of this invention can be achieved by employing the following technical solutions: In a first aspect, this application provides a steel-moving device, comprising two end sprockets, a conveyor chain, a billet holder, and a steel-pushing mechanism. The two end sprockets drive the conveyor chain to circulate. The conveyor chain is sleeved on the two end sprockets and drives the billet holder and the steel-pushing mechanism to move. The billet holder is disposed on the conveyor chain to carry the billet. The steel-pushing mechanism is sleeved on the rear chain shaft of the billet holder. The pushing arm of the steel-pushing mechanism is used to transmit the pushing force when the billet is upright and to limit the angle when it is tilted.

[0005] In one possible implementation, the steel moving device further includes a frame, a wheel set, and a track. The end sprocket is mounted on the frame, and the wheel set is mounted on the front and rear chain shafts of the billet seat for rolling within the track to bear the billet load. The track is fixed to the frame for guiding the wheel set to run in a straight line.

[0006] In one possible implementation, the steel-moving device further includes: A transmission tensioning device is connected to the conveyor chain and is used to drive the conveyor chain to move and adjust the tension of the conveyor chain.

[0007] In one possible implementation, the steel pushing mechanism is a unidirectional tilting structure, and the working position of the steel pushing mechanism includes an upright position and a tilting position. The billet seat can adjust the steel pushing mechanism to switch between the upright position and the tilting position as the conveyor chain moves.

[0008] In one possible implementation, the steel pushing mechanism includes a first steel pushing head and a second steel pushing head, which are respectively disposed on both sides of the billet seat.

[0009] In one possible implementation, during the forward movement of the conveyor chain, the steel pushing mechanism is in the upright position under non-forced conditions, and the steel pushing arm of the steel pushing mechanism protrudes from the upper surface of the billet seat and is located in the non-conveying direction of the billet to form a stop for the billet. During the reverse movement of the conveyor chain, when the steel pushing mechanism moves to the next steel billet, the steel pushing mechanism is in the tilting position, and the steel pushing mechanism is located below the steel billet until the steel pushing arm completely passes over the steel billet, and then returns to the upright position under its own weight.

[0010] In one possible implementation, the billet holder includes: A supporting body, which is connected to the conveyor chain; The top of the supporting body is provided with a bearing ramp for supporting steel billets. The height of the bearing ramp gradually increases along the conveyor chain. A limiting block is disposed on the bearing body and is used to adjust the position of the steel pushing mechanism.

[0011] In one possible implementation, the limiting block includes: The upright limiting surface is used to contact the pushing arm of the pushing mechanism to form a stop when the pushing mechanism moves to the upright position. The tilting limiting surface is used to contact the pushing arm of the pushing mechanism to form a stop when the pushing mechanism moves to the tilting position.

[0012] A second aspect of this application provides a steel transfer machine, including the steel transfer device described in any one of the first aspects.

[0013] A third aspect of this application provides a steel-moving method applied to the steel-moving apparatus described in any one of the first aspects, the steel-moving method comprising the following steps: The transmission tensioning device drives the conveyor chain in the forward direction, causing the conveyor chain to circulate. The billet holder on the conveyor chain carries the billet and pushes the billet to move along the conveying direction through the billet pushing mechanism. The billet holder limits the upright state of the billet pushing mechanism and transmits the pushing force through the pushing arm. The wheel set rolls in the track, transferring the load of the steel billet to the platform to achieve direct conveying without a slide rail. When the steel billet reaches the designated position, the transmission tensioning device stops, and the steel billet slides out of the steel billet seat under the action of gravity. The reverse drive conveyor chain moves, the steel pushing mechanism tilts over the steel billet to be moved and self-repositions, entering the next steel moving cycle.

[0014] The beneficial technical effects of this invention are as follows: According to this disclosure, the steel transfer device includes two end sprockets, a conveyor chain, a billet seat, and a steel pushing mechanism. The steel pushing mechanism and the billet seat can move with the conveyor chain to the position of the end sprockets, breaking through the stroke limitation of traditional built-in steel pushing heads and increasing the range of billet conveying. By integrating the chain plate section function and wheel-rail system into the billet seat, the billet is directly carried and transported by the chain, eliminating the need for traditional slide rail structures. The overall layout saves installation space. The front and rear wheel sets of the billet seat transfer the billet load to the platform through the rail, avoiding direct chain bearing and extending the service life of the equipment. The steel pushing mechanism has a bidirectional limiting function, reliably transmitting the pushing force when upright and automatically passing over the billet and resetting when tilted. It can realize continuous cyclic steel transfer operations, and is especially suitable for working conditions in the metallurgical industry where large-scale steel transfer is required and space is limited. While ensuring conveying efficiency, it significantly reduces equipment complexity and maintenance costs. Attached Figure Description

[0017] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of the present invention more clearly, the embodiments described below are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

The terms "install," "connect," "link," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "link" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] The first aspect of this application, as Figures 1-13As shown, a steel transfer device is provided, including two end sprockets 1, a conveyor chain 2, a billet seat 3, and a steel pushing mechanism 4. The two end sprockets 1 are used to drive the conveyor chain 2 to circulate. The conveyor chain 2 is sleeved on the two end sprockets 1 to drive the billet seat 3 and the steel pushing mechanism 4 to move. The billet seat 3 is set on the conveyor chain 2 to carry the billet. The steel pushing mechanism 4 is sleeved on the rear chain shaft of the billet seat 3. The pushing arm of the steel pushing mechanism 4 is used to transmit the pushing force when upright and to limit the angle when tilting.

[0021] The steel-moving device provided in this embodiment forms a motion unit with the steel billet seat 3 through the steel pushing mechanism 4. The steel pushing mechanism 4 and the steel billet seat 3 can move with the conveying chain 2 to the position of the end sprocket 1 and can run completely to the sprocket wrap angle area, which improves the range of steel billet conveying and breaks through the limitation of the traditional built-in steel pushing head being limited by the slide rail structure and only able to move in the straight section of the chain.

[0022] The steel transfer device provided in this embodiment integrates the chain plate section function and wheel-track 8 system in the billet seat 3, and the billet is directly carried and transported by the chain, eliminating the need for the traditional slide rail structure. The overall layout saves installation space. The front and rear wheel sets 7 of the billet seat 3 transfer the billet load to the frame 5 through the track 8, avoiding direct chain bearing and extending the service life of the equipment.

[0023] The steel-moving device provided in this embodiment has a bidirectional limiting function through the steel-pushing mechanism 4. When it is upright, it can reliably transmit the pushing force. When it is tilted, it automatically passes over the steel billet and resets. It can realize continuous cyclic steel-moving operations. It is especially suitable for working conditions in the metallurgical industry where large-scale steel-moving is required and space is limited. While ensuring conveying efficiency, it significantly reduces equipment complexity and maintenance costs.

[0024] In one possible implementation, such as Figures 1-4 As shown, the steel transfer device also includes a frame 5, a wheel set 7, and a track 8. The end sprocket 1 is mounted on the frame 5, and the wheel set 7 is mounted on the front and rear chain shafts of the billet seat 3 for rolling within the track 8 to bear the billet load. The track 8 is fixed to the frame 5 to guide the wheel set 7 to run in a straight line.

[0025] Among them, the platform 5 serves as the basic framework of the system, simultaneously acting as the installation platform for the end sprocket 1, the fixed base for the track 8, and the load-bearing skeleton of the overall device. Compared with traditional split-type supports, it eliminates the assembly error of multiple components.

[0026] Among them, the front and rear dual wheel sets 7 are designed to achieve even load rolling on straight sections, adaptive angle adjustment of the sprocket steering area, and wheel flanges to ensure the positioning accuracy of the track 8 and maintain the stability of the billet seat 3. The wheel sets 7 directly bear the vertical load, and the platform 5 as a whole absorbs dynamic impact.

[0027] Among them, the wheel set 7 rolls in the track 8, and the rolling friction replaces the traditional sliding friction, reducing wear. The segmented connection of the track 8 makes it easier to replace the worn section locally and to disassemble and install the wheel independently.

[0028] In one possible implementation, such as Figure 1 As shown, the steel transfer device also includes a transmission tensioning device 6, which is connected to the conveyor chain 2 and is used to drive the conveyor chain 2 to move and adjust the tension of the conveyor chain 2.

[0029] Among them, the transmission tensioning device 6 and the conveyor chain 2 form a closed loop system. It is flexibly started by a variable frequency motor, maintains the chain wrap angle by constant tension, and shares the radial load by the wheel set 7. It is suitable for tension maintenance under heavy-load impact conditions and can drive the conveyor chain 2 to move forward or backward.

[0030] In one possible implementation, such as Figure 5 As shown, the steel pushing mechanism 4 is a unidirectional tilting structure. The working positions of the steel pushing mechanism 4 include the upright position and the tilting position. The billet seat 3 can adjust the steel pushing mechanism 4 to switch between the upright position and the tilting position as the conveyor chain 2 moves.

[0031] When the steel pushing mechanism 4 is in the upright position, the steel pushing arm and the conveyor chain 2 form a rigid triangular support, and the oblique pushing surface precisely matches the contact angle of the steel billet; when the steel pushing mechanism 4 is in the tilting position, the steel pushing arm is limited by the height of the lower surface of the steel billet, triggering automatic tilting, and the steel pushing arm retracts to below the steel billet.

[0032] In one possible implementation, such as Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the steel pushing mechanism 4 includes a first steel pushing head and a second steel pushing head, which are respectively located on both sides of the billet seat 3.

[0033] Among them, the first and second push steel heads on both sides are configured with equal lengths, and the billet seat 3 is installed in the middle to enable the two push heads to work synchronously to eliminate the off-center load.

[0034] The steel pushing arm can be a triangular structure, which includes a pushing surface. When the steel pushing mechanism 4 is in an upright position, the pushing surface is approximately vertical and is used to contact the side of the steel billet to perform conventional steel pushing operations.

[0035] In one possible implementation, such as Figure 10 As shown, during the forward movement of the conveyor chain 2, the steel pushing mechanism 4 is in an upright position under non-stressed conditions. The pushing arm of the steel pushing mechanism 4 protrudes from the upper surface of the billet seat 3 and is located in the non-conveying direction of the billet, forming a stop for the billet. Figure 9As shown, during the reverse movement of the conveyor chain 2, when the steel pushing mechanism 4 moves to the next steel billet, the steel pushing mechanism 4 is in a tilted position. The steel pushing mechanism 4 is located below the steel billet until the steel pushing arm completely passes over the steel billet, and then returns to an upright position under the action of its own weight and eccentricity.

[0036] In the forward conveying mode, the billet is placed on the billet seat 3, and the pusher arm protrudes from the billet seat 3 to effectively stop the billet. In the non-stressed state, the pusher arm remains in a vertical position. In the reverse billet-crossing avoidance mode, the pusher arm is completely submerged under the billet until it passes the billet. After passing the billet, the pusher arm returns to an upright position.

[0037] In one possible implementation, such as Figures 11-13 As shown, the billet holder 3 includes a bearing body 31, a bearing inclined surface 32, and a limiting block 33. The bearing body 31 is connected to the conveyor chain 2. The top of the bearing body 31 is provided with a bearing inclined surface 32 for bearing the billet. Along the positive moving direction of the conveyor chain 2, the height of the bearing inclined surface 32 gradually increases. The limiting block 33 is set on the bearing body 31 to adjust the position of the pushing mechanism 4.

[0038] Among them, the bottom of the bearing body 31 is rigidly connected to the conveyor chain 2 to form a synchronous motion unit. The billet seat 3 not only carries the billet, but also serves as a chain plate link. The two inclined surfaces of its limiting block 33 (the inclined protrusion at the upper rear) can also limit the upright position and tilting position of the pushing steel head. The upper surface of the billet seat 3 in contact with the billet adopts a slightly inclined surface design towards the pushing steel head to prevent the billet from rushing out of the billet seat 3 during transportation.

[0039] In one possible implementation, such as Figures 9-11 As shown, the limiting block 33 includes an upright limiting surface 332 and a tilting limiting surface 331. When the steel pushing mechanism 4 moves to the upright position, the upright limiting surface 332 is used to contact the steel pushing arm of the steel pushing mechanism 4 to form a stop; when the steel pushing mechanism 4 moves to the tilting position, the tilting limiting surface 331 is used to contact the steel pushing arm of the steel pushing mechanism 4 to form a stop.

[0040] Among them, the center of gravity of the steel pushing mechanism 4 is set slightly to the upper left. Under its own weight, the steel pushing mechanism 4 stands up. The steel pushing arm of the steel pushing mechanism 4 contacts the vertical limiting surface 332 of the steel pushing head on the billet seat 3, stops swinging, and at the same time transfers the load of pushing the billet to the conveyor chain 2.

[0041] When the steel pushing mechanism 4 moves to the upright position, the steel pushing arm directly contacts the upright limiting surface 332 to form a rigid stop. The upright limiting surface 332 ensures that the steel pushing arm is stably locked under force, preventing accidental displacement during the billet conveying process.

[0042] When the pushing mechanism 4 moves to the tilting position, the tilting limiting surface 331 contacts the pushing arm and provides a buffer stop. The tilting limiting surface 331 often adopts an inclined or arc-shaped profile, and can also be combined with a return spring or damping device to absorb the tilting impact force and guide the pushing arm to smoothly transition to the avoidance position.

[0043] A second aspect of this application provides a steel transfer machine, including the steel transfer device of any one of the first aspects.

[0044] The steel transfer machine provided in this embodiment is suitable for long-distance, high-speed, and railless direct conveying of steel billets. The specially designed double unidirectional tilting, chain-side external pushing mechanism 4, combined with the steel billet seat 3, can meet the special steel transfer requirements of large-scale and compact space when the pushing head and steel billet seat 3 move to the end sprocket 1. The conveyor chain 2, pushing head and steel billet seat 3 designed in this way can be used in similar chain-type steel transfer equipment conveying occasions.

[0045] A third aspect of this application provides a steel-moving method, applied to the steel-moving apparatus of any one of the first aspects, the steel-moving method comprising the following steps: S1. The transmission tensioning device 6 drives the conveyor chain 2 to move in the forward direction, causing the conveyor chain 2 to move in a circular motion; S2. The billet seat 3 on the conveyor chain 2 carries the billet and pushes the billet to move along the conveying direction through the steel pushing mechanism 4. The billet seat 3 limits the upright state of the steel pushing mechanism 4 and transmits the pushing force through the steel pushing arm. S3. The wheel set 7 rolls in the track 8, transferring the billet load to the frame 5 to achieve direct conveying without a slide rail. When the billet reaches the designated position, the transmission tensioning device 6 stops, and the billet slides out of the billet seat 3 under the action of gravity. S4. The reverse drive conveyor chain 2 moves, the steel pushing mechanism 4 tilts over the steel billet to be moved and self-repositions, and enters the next steel moving cycle.

[0046] After the components are assembled, the transmission tensioning device 6 and the conveyor chain 2 are adjusted first. When the equipment is working, after the billet reaches the designated position, the transmission tensioning device 6 starts to rotate, driving the two end sprockets 1 to rotate, which in turn drives the conveyor chain 2 to pull the billet seat 3 and the steel pushing mechanism 4 to move. The upper surface of the billet seat 3 carries the billet to be transported, and the upper part of the steel pushing arm contacts the billet, so that the billet moves horizontally on the billet seat 3 in the direction of rotation of the conveyor chain 2. The wheel set 7 on the billet seat 3 and the adjacent chain links transfers the gravity load of the billet through the track. 8. The billet is transferred to the platform 5. After the billet reaches the designated position of the sprocket near the rear end of the platform 5, the transmission tensioning device 6 stops, the sprocket stops rotating, and the billet slides out of the billet seat 3 under the action of gravity and reaches the subsequent receiving equipment. The transmission tensioning device 6 rotates in the opposite direction, driving the conveyor chain 2 to move in the opposite direction. When the steel pushing arm passes the billet in the waiting position on the left, it can tilt clockwise in one direction to the contact surface of the billet seat 3 and tilt to a certain angle, passing the billet and reaching the left work position. The transmission tensioning device 6 stops rotating, and a new steel transfer process begins.
