The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] As Figures 1 to 6 shown, the present invention provides a billet transfer device across bays, which includes a track assembly 1 arranged between adjacent production bays. A trolley assembly 2 for horizontally transferring and transporting billets 8 (round billets) is supported on the track assembly 1. A transverse movement driving assembly 3 for driving the trolley assembly 2 to horizontally move between adjacent production bays is connected to the trolley assembly 2. A lifting driving assembly 4 for driving the track assembly 1 and the trolley assembly 2 to lift is arranged below the track assembly 1.

[0041] The lifting driving assembly 4 is used to lower and drive the track assembly 1 and the trolley assembly 2, place the billet that needs to be horizontally transferred across bays in a production bay on the trolley assembly 2 to complete billet picking; the transverse movement driving assembly 3 is used to horizontally move the trolley assembly 2 to a designated position in an adjacent production bay, and the lifting driving assembly 4 is used to raise and drive the track assembly 1 and the trolley assembly 2 so that the billet reaches the designated billet storage position to complete billet discharging.

[0042] The billet transfer device across bays of the present invention solves the problem of difficult billet transfer and transportation under the limited layout of the overhead crane bay in the workshop. The transverse movement driving assembly drives the trolley assembly to perform a horizontal transfer operation along the track assembly to complete the horizontal transportation work of round billets within the range; the lifting driving assembly drives the lifting operation of the track assembly and the trolley assembly to complete billet picking and discharging operations, ensuring relatively stable conveying operations, uniform cooling of billets and good straightness, and at the same time preventing excessive scratches on the billet surface.

[0043] The present invention realizes the normal transportation of produced round billets at positions where transportation cannot be carried out in the overhead crane bay and minimizes excessive surface scratches; the structure of the present invention is simple, the operation is reliable, and the investment cost is low, and it can be widely applied to new construction projects and renovation projects of round billet continuous casting.

[0044] Further, as Figure 1 、 Figure 2 shown, the transverse movement driving assembly 3 includes a wire rope 31 that can reciprocally move. The wire rope 31 is connected to the trolley assembly 2. An active drum 32 for winding the wire rope 31 (a non-standard designed drum, designed and manufactured according to actual production) is arranged at one end of the track assembly 1. A tensioning structure 5 for winding and tensioning the wire rope 31 is arranged at the other end of the track assembly 1. A transverse movement power part is connected to the active drum 32, and the transverse movement power part drives the active drum 32 to rotate to drive the wire rope 31 to move.

[0045] The transverse driving part drives the steel wire rope 31 to pull the trolley assembly 2, and the transverse transportation of round billets within a certain range can be carried out.

[0046] Furthermore, as Figure 1 , Figure 2 , Figure 3 shown, the lifting drive assembly 4 includes a lifting hydraulic cylinder 41 and a lifting cylinder support 42. One end of the lifting hydraulic cylinder 41 is hinged to the bottom end of the track assembly 1, and the other end of the lifting hydraulic cylinder 41 is hinged to the fixedly arranged lifting cylinder support 42.

[0047] When the lifting hydraulic cylinder 41 is fully retracted, the track assembly 1 is in a horizontal state; when the lifting hydraulic cylinder 41 extends, it pushes against the track assembly 1 to move obliquely upward, causing the track assembly 1 to rise. The design of the height difference can just cooperate with the work of taking and placing billets.

[0048] Furthermore, as Figure 1 , Figure 2 shown, the track assembly 1 includes a plurality of horizontal track beams 11 horizontally arranged between adjacent production bays. A trolley assembly 2 is respectively arranged on each track beam 11; two speed tracks 12 are arranged in parallel at intervals on each track beam 11, and the trolley assembly 2 can traverse between adjacent production bays along the speed tracks 12, ensuring that the track assembly 1 can operate; the speed tracks 12 are tracks formed by welding steel plates and are fixed to the track beams 11 in a bolt connection form.

[0049] Each track beam 11 is supported on a plurality of horizontally arranged synchronous beams 13 arranged in parallel at intervals, and each synchronous beam 13 is perpendicular to the track beam 11. In this embodiment, the synchronous beam 13 is fixed to the lower part of the track beam 11 in a bolt connection form.

[0050] In a specific embodiment of the present invention, as Figure 6 shown, the track assembly 1 is assembled by four rows of track beams 11 and three columns of synchronous beams 13. There are a total of four trolley assemblies 2, which are respectively arranged above each track beam 11, and through the connection of the steel wire rope 31 in the transverse drive assembly 3, synchronous movement in the same direction is achieved.

[0051] Furthermore, as Figure 1 , Figure 2 , Figure 3 shown, the track assembly 1 is supported on a plurality of guide roller assemblies 6 (the track assembly 1 is mainly a steel plate welded structure and is a frame structure on top of the guide roller assemblies 6); the guide roller assembly 6 includes a guide roller 61 and a guide roller support 62. The guide roller support 62 is fixed to the ground, the guide roller 61 is hinged to the guide roller support 62, and a plurality of lifting guide rails 14 are arranged at intervals at the bottom end of each track beam 11. The bottom surface of the lifting guide rail 14 is obliquely upward from the active reel 32 to the tensioning structure 5 ( Figure 1It slopes obliquely upward from left to right, consistent with the movement direction of the track assembly 1 when the lifting hydraulic cylinder 41 lifts. The bottom surface of each lifting guide rail 14 abuts and supports on each guiding roller 61. Each lifting guide rail and the guiding roller 61 move by friction to cooperate to achieve the oblique lifting function.

[0052] In a specific embodiment of the present invention, the guiding roller assembly 6 is arranged in four rows and four columns. Each guiding roller support 62 is a steel plate welded structure, fixed to the ground, providing an installation foundation for the guiding roller 61.

[0053] Furthermore, as Figure 1 , Figure 2 , Figure 3 shown, the lifting hydraulic cylinder 41 includes a lifting cylinder barrel 411 and a lifting cylinder rod 412; a synchronous beam 13 is provided with a cylinder rod hinge seat 43 on the side close to the driving drum 32, and the lifting cylinder rod 412 is hinged to the cylinder rod hinge seat 43; a lifting cylinder support 42 is arranged on the side of the cylinder rod hinge seat 43 close to the driving drum 32, and the lifting cylinder barrel 411 is hinged to the lifting cylinder support 42. The lifting cylinder rod 412 extends and retracts along the lifting cylinder barrel 411 to drive the track assembly 1 to lift.

[0054] In a specific embodiment of the present invention, a lifting cylinder support 42 is arranged on one side of a guiding roller support 62 (the two can be integrally manufactured) to achieve the supporting function for the lifting hydraulic cylinder 41.

[0055] Furthermore, as Figure 1 , Figure 2 shown, tensioning wheels 15 are respectively arranged at both ends of each track beam 11, and the tensioning wheels 15 are used to assist in tensioning the steel wire rope 31.

[0056] Furthermore, a billet storage table structure for supporting and storing round billets is arranged between two adjacent track beams 11.

[0057] According to the over-span requirement, two support points are arranged along the length direction of each track beam 11, and the two support points are respectively located in adjacent production bays. Billet storage table structures are respectively arranged at each support point. The billet storage table structures in each production bay are arranged in columns (on the same straight line). There is a height difference between the billet storage table structures at the two support points, which is convenient for cooperating with the lifting drive assembly 4 to achieve billet picking and placing.

[0058] As Figure 6 shown, the billet storage table structure can be divided into a large billet storage table 71 and a small billet storage table 72 according to the interval space between the track beams 11. The billet storage table structure is a steel plate welded structure, fixed to the ground. The top surfaces of the large billet storage table 71, the small billet storage table 72 and the trolley assembly 2 are arranged as an arc concave surface, which is convenient for stably preventing the casting billet 8.

[0059] The steel billets can be transported from the billet storage table in one production bay to the billet storage table in another production bay through the operation of the equipment.

[0060] When the lifting hydraulic cylinder 41 expands and contracts, under the contact action between the bottom surface of the lifting guide rail 14 and the guiding roller 61, the track assembly 1 will perform an inclined lifting motion. When the lifting hydraulic cylinder 41 is fully retracted, the cylinder body itself tends to be horizontal. The surface of the trolley assembly 2 on the track assembly 1 that supports the round billet is lower than the top surface of the billet storage table structure. When the lifting hydraulic cylinder 41 is fully extended, the situation is reversed. This height difference design is considered for billet picking and transportation.

[0061] Furthermore, as shown in Figure 1 and Figure 4 , the transverse driving part includes a driving motor 33 (an asynchronous motor that provides the power source), a speed reducer 34, a driving shaft, and a power part support 35. The driving motor 33 and the speed reducer 34 are fixedly arranged on the power part support 35. The driving motor 33 is connected to the speed reducer 34. The speed reducer 34 is in the form of a double output shaft to achieve the transmission function of driving multiple driving drums 32 to rotate.

[0062] On both sides of the speed reducer 34, a driving shaft (a steel shaft made by machining, symmetrically installed on both sides of the speed reducer and connected through a coupling) is respectively connected. The driving drum 32 is connected to the driving shaft. The driving motor 33 drives the driving drum 32 to rotate through the speed reducer 34 and the driving shaft to drive the steel wire rope 31 to move.

[0063] The steel wire rope 31 pulls the trolley assembly 2. Under the control of the transverse driving part, the trolley assembly 2 moves synchronously to the left or right ( Figure 1 the left and right directions in

[0064] ). The trolley assembly 2 is an important tool for transporting round billets. The power part support 35 is a steel plate welded part and is fixed on the ground. A bearing seat is fixedly installed on the power part support 35, and the driving shaft rotates and is supported in the bearing seat.

[0065] Furthermore, as shown in Figure 1 and Figure 5 , the tensioning structure 5 includes a tensioning drum 51 (a non-standard designed drum, designed and manufactured according to actual production) around which the tensioning steel wire rope 31 is wound. The tensioning drum 51 is hinged to a fixedly arranged tensioning support 52.

[0066] Below the tensioning support 52, a tensioning structure base 53 is provided. The tensioning support 52 is fixed to the tensioning structure base 53 by bolts. Both of them are steel plate welded structures, and the tensioning structure base 53 is fixed to the ground by anchor bolts.

[0067] A buffer spring 54 is provided on the tensioning structure 5, and the buffer spring 54 plays a buffering role.

[0068] The tensioning structure 5 ensures that the steel wire rope 31 is in a certain tension state (i.e., has a certain tightness), slightly compensates for the tensile deformation of the steel wire rope 31 under the action of tension, and the expansion and contraction deformation caused by the temperature difference, ensuring a certain appropriate tension between the transverse moving power part and the tensioning structure 5, thereby promoting the normal operation of the equipment.

[0069] The working process of an embodiment of the present invention is as follows:

[0070] When a long round billet is placed on Figure 4 the left column of the billet storage table structure in, the height of the trolley assembly 2 should be below the round billet. The lifting hydraulic cylinder 41 extends, causing the trolley assembly 2 to gradually drive the round billet until it leaves the billet storage table structure. Then, by the action of the transverse movement drive assembly 3, the driving drum 32 is rotated to drive the steel wire rope 31 to move, thereby pulling the trolley assembly 2 to achieve the transverse movement of the trolley assembly 2 and the round billet. When moving to the oblique upper part of the billet storage table structure on the other side, it can stop, and then the height of the track assembly 1 is reduced by the telescopic movement of the hydraulic cylinder, and then the round billet is placed on the billet storage table structure.

[0071] As described above, the billet transfer device of the present invention has the following beneficial effects:

[0072] The billet transfer device of the present invention solves the problem of difficult billet transfer transportation under the limited conditions of the overhead crane bay layout in the workshop. The trolley assembly is driven by the transverse movement drive assembly to perform transverse transfer operation along the track assembly to complete the transverse transportation work of the round billet within the range; the track assembly and the trolley assembly are driven by the lifting drive assembly to perform lifting operations to complete the billet taking and placing operations, ensuring relatively stable conveying operations, uniform cooling of the billet and good straightness, and at the same time preventing excessive scratches on the surface of the billet.

[0073] The present invention realizes the normal transportation of the produced round billets at the positions where the overhead crane bay cannot perform transportation, and minimizes excessive surface scratches; the structure of the present invention is simple, the action is reliable, and the investment cost is low, and it can be widely applied to new construction projects and renovation projects of round billet continuous casting.

[0074] The above are only the schematic specific embodiments of the present invention and are not intended to limit the scope of the present invention.
