Description

Technical Field

[0001] This application relates to the field of power supply devices, and more specifically, to a power supply device for a multi-flow ramp billet transverse transfer trolley. Background Technology

[0002] In continuous casting slab production, hot discharge of the slab is required, and a transverse trolley is a common device for this process. The transverse trolley uses a motor and reducer to drive the slab, which is supported by the trolley body, to travel along a fixed transverse track. Then, rollers on the trolley body transport the slab to the corresponding roller conveyor on the hot rolling production line. Typically, the transverse trolley travels at a perpendicular angle to the direction of the roller conveyor on the hot rolling production line. The power supply for the transverse trolley motor and other electrical equipment on the trolley is usually obtained from the power supply device of the sliding line trolley.

[0003] However, if three or more transverse trolleys are set up simultaneously on two or more slab production lines to produce billets, and if the transverse trolleys have uphill and downhill problems during their movement, the conventional solution of using cables and sliding trolleys for power supply will seriously affect the movement speed and the service life of the sliding trolleys. Furthermore, if there are too many sliding trolleys during the movement of the transverse trolleys on long-distance slopes, there is also the problem of excessive load and easy damage to the power supply equipment. Utility Model Content

[0004] The purpose of this application is to provide a power supply device for a multi-flow ramp billet transverse transfer trolley, which can switch to achieve stable power supply when the sliding wire assembly fails, and effectively reduce the number of sliding wires used, thereby reducing the cost of use.

[0005] This application is implemented as follows:

[0006] This application provides a power supply device for a multi-flow ramp billet transverse transfer trolley, which is used to supply power to at least three transverse transfer trolleys that are moved on the top track of the power supply platform. The transverse transfer trolleys move along the track to transfer the billet from the billet discharge roller conveyor on one side of the power supply platform to the hot delivery roller conveyor on the other side of the power supply platform. The power supply platform is provided with at least two power supply cavities arranged along its width direction. Each power supply cavity is provided with a fixed bracket, and each fixed bracket is connected to at least two sliding line assemblies.

[0007] Two transverse trolleys at both ends are each connected to a trolley power take-up bracket. The power take-up brackets of the two transverse trolleys at both ends extend into two power take-up cavities. The transverse trolley in the middle is connected to two trolley power take-up brackets. The two power take-up brackets of the transverse trolley in the middle extend into two power take-up cavities. Each trolley power take-up bracket is connected to at least two sets of electrical connectors. Each set of electrical connectors of each trolley power take-up bracket slides and presses against each sliding wire assembly in the power take-up cavity.

[0008] In some alternative implementations, the top of the power-collecting platform is provided with an opening that communicates with each power-collecting cavity, and the trolley power-collecting bracket extends into the corresponding power-collecting cavity through the opening.

[0009] In some alternative implementations, buffer strips that elastically press against the sides of the power take-off bracket of the corresponding trolley are provided on both sides of the opening.

[0010] In some alternative implementations, at least one slide rail assembly connected to the fixed bracket is an aluminum-based rigid slide rail.

[0011] In some alternative implementations, at least one slide rail assembly connected to the fixed bracket is a copper-based rigid slide rail.

[0012] In some alternative implementations, the copper-based rigid slide rail is positioned above the corresponding aluminum-based rigid slide rail.

[0013] In some alternative implementations, an insulator assembly is connected between the fixed bracket and the slide rail assembly.

[0014] In some alternative implementations, the bottom of the insulator assembly is connected to a fixed bracket via a resilient rubber seat.

[0015] In some alternative implementations, the power-collecting platform includes an upper platform and a lower platform arranged in parallel, and an inclined platform at both ends connected to the upper platform and the lower platform respectively.

[0016] In some alternative implementations, the transition points of the slide rail assembly at both ends of the tilting platform are rounded.

[0017] The beneficial effects of this application are as follows: The power supply device of the multi-flow ramp billet transverse trolley provided by this application enables the transverse trolley to extend into the power supply cavity through the trolley power supply bracket and connect to the electrical connector and slide to the sliding line assembly to obtain power, which can ensure the stability of the power supply operation. At the same time, the transverse trolley located in the middle extends into the two power supply cavities through the two trolley power supply brackets and connects to the electrical connector and slide to the corresponding sliding line assembly to obtain power, which can switch between different sliding line assemblies during the power supply process, thereby switching to achieve stable power supply when the sliding line assembly fails, and effectively reducing the number of sliding lines used and reducing the cost of use.

[0029] The following describes in further detail the features and performance of the power supply device for the multi-flow ramp billet transverse transfer trolley of this application, with reference to embodiments.

[0030] like Figure 1 and Figure 2 As shown, this application embodiment provides a power supply device for a multi-strand slab continuous casting machine with a ramp for billet transfer trolley, which is used to supply power to three transfer trolleys 200 that are moved on the top of the power supply platform 100. Two billet discharge roller conveyors 300 are respectively provided at both ends of one side of the power supply platform 100, and one hot conveying roller conveyor 310 is respectively provided at both ends of the other side of the power supply platform 100. The four billet discharge roller conveyors 300 are billet discharge devices for two twin-strand slab continuous casting machines. The two hot conveying roller conveyors 310 respectively transport the slabs to the roller conveyors in the rear rolling mill workshop. Two parallel tracks 110 are provided on the top of the power supply platform 100 and extend along their length direction. The three transfer trolleys 200 move along the tracks 110 to transfer the slabs from the four billet discharge roller conveyors 300 on one side of the power supply platform 100 to the two hot conveying roller conveyors 310 on the other side of the power supply platform 100.

[0031] The power-collecting platform 100 includes an upper platform 101 and a lower platform 102 arranged parallel to each other, and an inclined platform 103 connected to the upper platform 101 and the lower platform 102 at both ends. The upper platform 101, the inclined platform 103, and the lower platform 102 are arranged sequentially and extend along the same straight line. The power-collecting platform 100 has two power-collecting cavities 120 spaced apart along its width. The top two sides of the power-collecting platform 100 have openings 150 communicating with the two power-collecting cavities 120. The power-collecting cavities 120 and the openings 150 extend along the length of the power-collecting platform 100. The inner wall of each power-collecting cavity 120 is connected to a fixed bracket 130 spaced apart along its length. Each fixed bracket 130 is connected to four horizontally arranged vertically. The fixed branch plates 131 are arranged at intervals. The top surface of the corresponding fixed branch plate 131 of each fixed bracket 130 supports and is connected to a sliding wire assembly 140. The top surface of each fixed branch plate 131 is supported and connected to the corresponding sliding wire assembly 140 by four insulator assemblies 170. An elastic rubber seat 180 is connected between the bottom of each insulator assembly 170 and the fixed branch plate 131. The turning points of the sliding wire assembly 140 at both ends of the inclined platform 103 where it connects to the upper platform 101 and the lower platform 102 are rounded. The sliding wire assemblies 140 connected to the upper two fixed branch plates 131 in each power taking cavity 120 are copper-based rigid sliding wires, and the sliding wire assemblies 140 connected to the lower two fixed branch plates 131 in each power taking cavity 120 are aluminum-based rigid sliding wires. In this embodiment, each power extraction cavity 120 has four four-phase AC380V rigid sliding contact lines in the sliding contact assembly 140 connected to the three upper fixed branch plates 131, and four two-phase AC220V rigid sliding contact lines in the sliding contact assembly 140 connected to the lowermost fixed branch plate 131.

[0032] Two transverse trolleys 200 located at both ends are each connected to a trolley power take-off bracket 210. The trolley power take-off brackets 210 of the two transverse trolleys 200 located at both ends extend into two power take-off cavities 120 and are connected to four power take-off branch plates 211 that correspond one-to-one with the fixed branch plates 131. Two trolley power take-off brackets 210 are connected to the two sides of the transverse trolley 200 located in the middle. The two trolley power take-off brackets 210 of the transverse trolley 200 located in the middle extend into two power take-off cavities 120 and are connected to four power take-off branch plates 211 that correspond one-to-one with the fixed branch plates 131. Each power take-off branch plate 211 is connected to four electrical connectors 220 that slide against the sliding wire assembly 140 on the corresponding fixed branch plate 131. Buffer strips 160 that elastically press against the sides of the trolley power take-off brackets 210 are provided on both sides of the opening 150.

[0033] The power collection device for the multi-flow ramp billet traverse trolley provided in this embodiment of the application involves setting two power collection cavities 120 within the power collection platform 100. Each power collection cavity 120 is connected to four sliding line assemblies 140 via fixed brackets 130. Three traverse trolleys 200, movable on the top track 110 of the power collection platform 100, are each connected to a trolley power collection bracket 210. Each trolley power collection bracket 210 extends into the power collection cavity 120 and is connected to the corresponding sliding line assembly 140's electrical connector 220 via spaced-apart power collection branch plates 211. This ensures that when the three traverse trolleys 200 move along the track 110, they drive the respective power collection branch plates 211 of the trolley power collection brackets 210. The power connectors 220 press against and move along the sliding wire assemblies 140 on the fixed branch plates 131 of the fixed bracket 130 in the corresponding power receiving cavity 120 to ensure the stability of power receiving. In particular, when the transverse trolley 200 moves along the power receiving platform 100 to the downhill and uphill sections between the upper platform 101 and the inclined platform 103 and between the inclined platform 103 and the lower platform 102, the power connectors 220 on the power receiving branch plates 211 of the trolley power receiving bracket 210 press against and move along the sliding wire assemblies 140 on the fixed branch plates 131 of the fixed bracket 130 in the corresponding power receiving cavity 120 to avoid power receiving failures caused by poor contact, and ensure that the transverse trolley 200 moves stably along the track 110 to transfer the slab.

[0034] The two transverse trolleys 200 located at both ends are used to move along the track 110 to transfer the slabs output from the four billet discharge roller conveyors 300 at both ends of one side of the power take-up platform 100 to the two hot conveying roller conveyors 310 on the other side of the power take-up platform 100. The transverse trolley 200 located in the middle is used to stop at the upper platform 101 or lower platform 102 near the inclined platform 103 to wait for standby. When the two transverse trolleys 200 located at both ends malfunction or need to be repaired or maintained, the transverse trolley 200 located in the middle is used to replace them for slab transfer operations.

[0035] The transition points where the sliding rail assembly 140 connects to the upper platform 101 and lower platform 102 at both ends of the inclined platform 103 are rounded to reduce the possibility of the electrical connector 220 and the upper sliding rail assembly 140 disengaging when the traverse trolley 200 passes through the transition points between the uphill and downhill slopes. The opening 150 is provided with elastically pressing buffer strips 160 on both sides of the corresponding trolley power take-up bracket 210. These buffer strips 160 provide elastic pressure and buffering on both sides of the trolley power take-up bracket 210, ensuring the stability of the trolley power take-up bracket 210 as the traverse trolley 200 moves along the track 110. This allows the electrical connectors 220 on each power take-up branch plate 211 of the trolley power take-up bracket 210 to stably slide and press against the sliding rail assembly 140 on each fixed branch plate 131 of the fixed bracket 130 within the corresponding power take-up cavity 120. Each insulator assembly 170 has an elastic rubber seat 180 connected between its bottom and the fixed branch plate 131. This ensures that the insulator assembly 170 is elastically connected to the sliding wire assembly 140 to adapt to the positional changes of the electrical connectors 220 on each power-taking branch plate 211 of the trolley power-taking bracket 210 connected to the traverse trolley 200 when going up or down slopes. This ensures that the electrical connectors 220 stably slide and press against the sliding wire assemblies 140 on each fixed branch plate 131 of the fixed bracket 130 in the corresponding power-taking cavity 120.

[0036] The transverse trolley 200 located in the middle is connected to two trolley power-receiving brackets 210. The two trolley power-receiving brackets 210 extend into two power-receiving cavities 120 and are connected to the electrical connectors 220 of the corresponding sliding rail assemblies 140 through spaced power-receiving branch plates 211. This allows the transverse trolley 200 located in the middle to selectively draw power from the corresponding sliding rail assemblies 140 in the two power-receiving cavities 120. This enables the transverse trolley 200 located in the middle to switch during the power-receiving process. On the one hand, this reduces the number of sliding rail assemblies 140 used and lowers the construction cost. On the other hand, it allows switching to a backup sliding rail assembly 140 to draw power when a sliding rail assembly 140 is damaged, ensuring the stable operation of the transverse trolley 200.

[0037] The sliding contact assemblies 140 connected to the two upper fixed branch plates 131 within each power receiving cavity 120 are copper-based rigid sliding contact lines, while the sliding contact assemblies 140 connected to the two lower fixed branch plates 131 within each power receiving cavity 120 are aluminum-based rigid sliding contact lines. The use of aluminum-based rigid sliding contact lines allows for long-distance power supply lines, effectively reducing construction costs. The sliding contact assemblies 140 connected to the three upper fixed branch plates 131 within each power receiving cavity 120 are each equipped with four four-phase AC380V rigid sliding contact lines, while the sliding contact assemblies 140 connected to the lowest fixed branch plate 131 within each power receiving cavity 120 are equipped with four two-phase AC220V rigid sliding contact lines. This allows for adaptation to the power supply requirements of different specifications of the transverse trolleys 200, thus ensuring the power supply requirements of each transverse trolley 200 while reducing the number of sliding contact assemblies 140 used.

[0038] In other alternative embodiments, the number of power-collecting cavities 120 provided inside the power-collecting platform 100 may be three or more.

[0039] In other alternative embodiments, the number of traverse trolleys 200 that are moved on the top track 110 of the power supply platform 100 may be four or more.

[0040] In other alternative embodiments, the number of trolley power take-up brackets 210 connected to each transverse trolley 200 can be two or more.

[0041] In other alternative embodiments, the fixed brackets 130 arranged at intervals along the length direction connected to the inner wall of each power-collecting cavity 120 can also be connected to form a whole.

[0042] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
