[0002] In modern industrial production, hot cast billet roller conveyors are one of the key equipment used to transport high-temperature cast billets from one station to another. Traditional conveyors usually use a fixed roller design. Although this design is simple and reliable, it has great limitations when facing complex production processes and changing production needs. Especially when the conveying route needs to be dynamically adjusted, the traditional fixed roller design is difficult to meet the needs of fast and flexible production line changes.

[0008] Preferably, the traction assembly comprises: An electric telescopic rod, which is installed at the bottom of the rotating seat through a bracket; A lifting frame, which is installed at the output end of the electric telescopic rod; A fixed pulley, which is installed in the rotating seat through a pulley frame; A traction rope, one end of which is fixed on the pin rod, and the other end of which is fixed on the lifting frame after passing through a fixed pulley.

[0009] Preferably: a mounting plate is fixed to the outer wall at the bottom of the first roller frame, a vertical pole is fixed to the outer wall at the bottom of the mounting plate, a mounting seat is installed on the top of the mounting platform, and a pressure sensor assembly is arranged on the mounting seat.

[0012] Preferably, the conveying roller of the first roller conveyor is provided with linearly distributed annular grooves, and a guide assembly is installed on the vertical plate structure of the first roller conveyor frame, and the guide assembly is an inverted "eight"-shaped structure.

[0015] The beneficial effects of the present invention are: The present invention is provided with a positioning detection mechanism, which can work based on the rotation drive part to drive the rotating seat to rotate, so as to realize the cooperation between the first roller and the two second rollers or the two third rollers, thereby realizing the conduction of different conveying routes. In addition, due to the provision of the positioning detection mechanism, after the rotation, based on the resetting of the traction component, the pin rod can be extended. If it passes through the slide to compress the contact switch, the control system controls the corresponding second roller or third roller to work based on the change of the electrical signal.

[0016] The present invention arranges a traction component, and can control the extension and retraction of the pin rod through the traction rope based on the extension and retraction of the output end of the electric telescopic rod.

Based on the addition of the pressure sensor assembly structure, it can be used as a part of control. For example, when the pressure sensor detects that the movement is in place, the system controls the rotation drive motor to stop working and makes the hydraulic cylinder or the electric telescopic rod work to achieve more efficient control. Moreover, since the rolling ball is a spherical structure, its contact area with the pressure sensor assembly is smaller, so it can improve the accuracy of the detection point while ensuring the smoothness of the movement.

[0018] The present invention can guide the hot cast billet being transported and adjust its position by arranging a guide component. Since the structure of the guide component cooperates with the linearly distributed annular grooves and based on structural limitations, the spherical head can be maintained above the axis of the corresponding first roller, while ensuring the guiding ability, the guiding position is made more precise and the structure operates more stably.

[0019] Since the present invention is provided with structures such as an annular groove and a spherical head, the spherical head can be adjusted to the corresponding annular groove according to needs, so as to adjust the angle of the guide plate and achieve the purpose of changing the guiding position; during the process, the collar can be moved on the L-shaped rod, and the telescopic rod can change its length by telescoping, so as to cooperate with the position adjustment of the spherical head. After the adjustment is completed, the collar is fixed by the top screw to ensure the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0024] A hot casting billet roller conveyor, such as Figure 1-7 As shown, including: A mounting platform 1, on which a rotating seat 27 is rotatably mounted; A rotation driving unit, which is mounted on the mounting platform 1 and is used to drive the rotating seat 27 to rotate; A first roller frame 9, the first roller frame 9 is installed on the top outer wall of the rotating seat 27, and a first roller 10 is installed in the first roller frame 9; A second roller frame 3, the second roller frame 3 is arranged on both sides of the first roller frame 9, and a second roller 11 is installed on the second roller frame 3; The third roller frame 5 is arranged on the other two sides of the first roller frame 9. The first roller frame 9 is equipped with a third roller 6. Based on the operation of the rotation drive unit, the rotating seat 27 is driven to rotate, so that the first roller 10 cooperates with the two second rollers 11 or cooperates with the two third rollers 6; Positioning detection mechanism, the positioning detection mechanism is used to detect whether the first roller frame 9 is rotated into place; The positioning detection mechanism comprises: A guide frame 18, the guide frame 18 is installed below the end of the first roller frame 9; A pin rod 17, the pin rod 17 is slidably connected to the inner wall of the guide frame 18, and one end of the pin rod 17 is connected to the guide frame 18 via a pin rod spring 19; A traction assembly, which is used to pull the pin rod 17 to retract it; Support frame, the support frame is installed below one end of the second roller frame 3 and the third roller frame 5 close to the first roller frame 9; The slide 16 is slidably mounted on the inner wall of the support frame, and the end of the slide 16 is connected to the support frame through the slide spring 13. The slide 16 is provided with a through hole for inserting the pin rod 17; A fixing frame 14, the fixing frame 14 is installed on the outer wall of one side of the slide frame 16, and a contact switch 15 is arranged on the fixing frame 14, the position of the contact switch 15 is adapted to the perforation, and the contact switch 15 is respectively connected to the control circuit of the second roller 11 or the third roller 6 at the respective position; By setting up a positioning detection mechanism, it is possible to drive the rotating seat 27 to rotate based on the working of the rotating drive unit, so as to realize the coordination of the first roller 10 with the two second rollers 11 or with the two third rollers 6, thereby realizing the conduction of different conveying routes. In addition, due to the setting of the positioning detection mechanism, after the rotation, based on the resetting of the traction component, the pin 17 can be extended. If it passes through the slide 16 to press the contact switch 15, the control system controls the corresponding second roller 11 or the third roller 6 to work based on the change of the electrical signal. This scheme can control the conveying after the first roller 10 is successfully docked with the corresponding conveying route.

[0025] In order to provide more transportation paths and meet different transportation solutions; Figure 1 As shown, one or more of the second roller 11 and the third roller frame 5 are of multi-layer design, and the number of slides 16 is adapted to the number of layers in the multi-layer design; A lifting mechanism is provided at the bottom of the mounting platform 1, and the lifting mechanism is used to control the lifting of the mounting platform 1; The lifting mechanism includes a base 12 and a hydraulic cylinder 2 . The hydraulic cylinder 2 is mounted on the base 12 , and an output end of the hydraulic cylinder 2 is fixed to the bottom of the mounting platform 1 .

[0026] In order to facilitate the driving of the rotating seat 27 to rotate; Figure 3 , Figure 5 As shown, the rotation driving unit includes: A rotation drive motor 25, which is installed at the bottom of the mounting platform 1; The drive gear, the shaft of the drive gear is drivingly connected to the output end of the rotating drive motor 25, and the outer side of the rotating seat 27 is provided with circumferentially distributed convex teeth, and the drive gear is meshed with the convex teeth.

[0027] In order to facilitate synchronous control of the extension and contraction of each pin 17; Figure 6 As shown, the traction assembly includes: An electric telescopic rod 26, which is mounted on the bottom of a rotating seat 27 through a bracket; A lifting frame 28, the lifting frame 28 is installed at the output end of the electric telescopic rod 26; A fixed pulley 29, which is installed in the rotating seat 27 through a pulley frame; A traction rope 20, one end of which is fixed to the pin rod 17, and the other end of which is fixed to the lifting frame 28 after passing through a fixed pulley 29; By setting up a traction component, the extension and retraction of the pin rod 17 can be controlled by the traction rope 20 based on the extension and retraction of the output end of the electric telescopic rod 26. Due to the use of multi-point detection, when the contact switch 15 adopts a series structure, the structural accuracy is higher. When the first roller frame 9 is slightly skewed and some contact switches 15 are not triggered, the roller will not transport, ensuring that the conveying angle is stable and reliable; when the contact switch 15 adopts a parallel structure, it has a certain fault tolerance and is more suitable for scenarios with low conveying requirements; the series and parallel logic of the contact switch 15 can be adjusted based on requirements to meet different usage requirements, with high flexibility.

[0028] In order to improve the control mechanism and better realize automatic control; Figure 3 , Figure 5 As shown, a mounting plate 21 is fixed to the bottom outer wall of the first roller frame 9, a vertical pole is fixed to the bottom outer wall of the mounting plate 21, a mounting seat 8 is installed on the top of the mounting platform 1, and a pressure sensor assembly 7 is arranged on the mounting seat 8; A ball seat 23 is fixed to the bottom end of the vertical rod, a rolling ball 24 is movably installed in the ball seat 23, and the pressure sensor assembly 7 is located on the movement path of the rolling ball 24; By setting up structures such as the pressure sensor assembly 7 and the ball 24, it is possible to detect whether the ball 24 has moved into position, thereby determining whether the first roller frame 9 has moved into position. Based on the addition of the pressure sensor assembly structure, it can be used as a part of the control. For example, when the pressure sensor detects that the movement is in position, the system controls the rotation drive motor 25 to stop working, and makes the hydraulic cylinder 2 or the electric telescopic rod 26 work, so as to achieve more efficient control. Moreover, since the ball 24 is a spherical structure, its contact area with the pressure sensor assembly 7 is smaller, so it can improve the accuracy of the detection point while ensuring the smoothness of the movement.

[0029] like Figure 1 , Figure 2 As shown, both sides of the first roller frame 9, the second roller frame 3 and the third roller frame 5 are vertical plate structures, and the top surfaces of the vertical plate structures are detachably mounted with shields 4. Example

[0030] A hot casting billet roller conveyor, such as Figure 1-7 As shown, in order to facilitate the guidance of the hot cast billet being transported, this embodiment makes the following improvements on the basis of Embodiment 1: a linearly distributed annular groove 22 is provided on the conveying roller of the first roller 10, and a guiding assembly is installed on the vertical plate structure of the first roller frame 9, and the guiding assembly is an inverted "eight" shape structure.

[0031] In order to better guide the hot cast billet; Figure 7 As shown, the guide component includes: The column is arranged on the vertical plate structure of the first roller frame 9, and a rotating drum 36 is rotatably mounted on the column, and the rotating drum 36 and the vertical plate structure are connected by a second supporting spring 35; A telescopic rod 34, one end of which is fixed to a rotating drum 36, a terminal post 30 is fixed to the free end of the telescopic rod 34, a spherical head 38 is provided at the bottom of the terminal post 30, and the spherical head 38 slides in an annular groove 22; The guide plate 39 is fixed to the outer wall of one side of the end column 30 .

[0032] To improve structural stability; Figure 7 As shown, an L-shaped rod 32 is installed on the vertical plate structure of the first roller frame 9, and a collar 33 is movably installed on the L-shaped rod 32. The inner wall of one side of the collar 33 is connected by a thread with a top screw for fixing the collar 33 on the L-shaped rod 32; a rotating rod 37 is rotatably installed at the bottom of the collar 33, and the top of the end column 30 is slidably connected to the inner wall of the bottom of the rotating rod 37, and the rotating rod 37 and the end column 30 are connected by a first supporting spring 31; the position of the L-shaped rod 32 is adapted to the position of the axis of the first roller 10; By setting the guide assembly, the hot cast billet being transported can be guided and its position can be adjusted. Since the structure of the guide assembly cooperates with the linearly distributed annular groove 22 and based on the limitation of the structure, the spherical head 38 can be kept above the axis of the corresponding first roller 10, while ensuring the guiding ability, the guiding position is made more accurate and the structure is operated more stably; Since the annular groove 22, spherical head 38 and other structures are provided, the spherical head 38 can be adjusted to the corresponding annular groove 22 according to needs, so as to adjust the angle of the guide plate 39 to achieve the purpose of changing the guiding position; during the process, the ring 33 can be moved on the L-shaped rod 32, and the telescopic rod 34 can change its length by telescoping, so as to cooperate with the position adjustment of the spherical head 38. After the adjustment is completed, the ring 33 is fixed by the top screw to ensure the stability of the structure.

[0033] In order to facilitate the steering conveying, Figure 8 , Fig. 9As shown, an arc roller frame 40 is connected to the end of the second roller frame 3, and conveying rollers 42 distributed along the arc are installed on the arc roller frame 40. A driving motor 41 for driving the conveying rollers 42 to work is installed on one side of the arc roller frame 40.

[0034] The above is only a preferred specific implementation of the present invention. For the parts that are not disclosed in detail, such as specific circuit connection methods, or instrument models, those skilled in the art can use conventional technical means to implement them, so they are not elaborated here.
