Description

Technical Field

[0001] The invention relates to prefabricated beam production equipment and methods, and in particular to a busbar power supply device and a working method, a prefabricated beam production line and a transfer method. Background Art

[0002] For the prefabrication production line of small box girders or T-beams, the longitudinal transfer vehicle needs to be transversely transferred from the end of the production line to the return line via the transverse transfer vehicle in the transverse transfer ferry area, and then longitudinally transferred to the other end along the return line, and then transversely transferred back to the head end of the production line, forming a production line cycle. The power supply problem of the longitudinal transfer vehicle needs to be solved during this cycle. The traditional method is to use a reel for power supply, manually plug in, and manually retract the reel. During use, problems such as plug damage and accidental power outages often occur. Power outages can easily damage the electronic control components of the longitudinal transfer vehicle. Manual plugging in also poses safety risks, and manual operation cannot achieve automated production, and the reliability is not high. Using busbars for power supply can solve the problems of reel power supply, but when using busbars for power supply, it is necessary to solve the problem of continuous power supply when the longitudinal transfer vehicle enters or leaves the transverse transfer ferry area.

[0003] Currently, there are two main ways of transverse ferrying. The first is to dig a foundation pit and set up a transverse ferry: a transverse ferry is set up in the foundation pit of the ferry area, and a longitudinal track is set on the top of the transverse ferry. The longitudinal track can be aligned with the production line / return line track. The longitudinal transfer vehicle moves directly to the top of the transverse ferry and then moves horizontally as a whole. This method is costly and cumbersome to maintain (including digging foundation pits, draining, cleaning garbage, etc.). This method sets a busbar on the transverse ferry and sets two collectors before and after the longitudinal transfer vehicle to ensure continuous power supply; the second is a jack-up transverse transfer vehicle: the longitudinal transfer track is laid continuously to the transverse transfer area, the transverse transfer vehicle first avoids the longitudinal transfer vehicle, moves the longitudinal transfer vehicle to the transverse ferry area, and then moves the transverse transfer vehicle horizontally to the bottom of the longitudinal transfer vehicle, lifts up the longitudinal transfer vehicle and then moves horizontally. This method avoids the problems of high cost and cumbersome maintenance in the first method, but because the longitudinal transfer vehicle needs to avoid the longitudinal transfer vehicle when it moves to the transverse ferry area, the continuous power supply solution of the first method cannot be directly applied. If the busbar is fixed directly on the side of the longitudinal track, although the problem of continuous power supply when the longitudinal vehicle enters or leaves the transverse ferry area can be solved, when the longitudinal vehicle moves transversely, the collector on the longitudinal vehicle and the busbar fixed on the side of the production line will interfere with each other, so the traditional manual plug-in method is still used. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a busbar power supply device that can achieve continuous power supply when a longitudinal transfer vehicle enters or leaves a transverse transfer area and does not interfere with the transverse movement of the longitudinal transfer vehicle.

[0014] As a further improvement of the above technical solution: a drag chain is connected to the rear end of the telescopic member in the telescopic direction.

[0015] As a further improvement of the above technical solution: a trigger component for controlling the extension and retraction of the first busbar is provided between the bracket and the longitudinal transfer vehicle.

[0016] A working method of the above-mentioned busbar power supply device,

[0017] When the longitudinal transfer vehicle intends to enter the transverse transfer ferry area or leave the transverse transfer ferry area, the drive assembly drives the telescopic member to extend, and the telescopic member drives the first busbar to extend to the transverse transfer ferry area to supply power to the collector on the longitudinal transfer vehicle;

[0018] When the longitudinal transfer vehicle is to move transversely in the transverse transfer ferry area, the driving assembly drives the telescopic member to retract, and the telescopic member drives the first busbar to retract from the transverse transfer ferry area.

[0019] A prefabricated beam production line, comprising a longitudinal track, a return track arranged in parallel with the longitudinal track, a longitudinal vehicle arranged on the longitudinal track, transverse ferry areas arranged at both ends of the longitudinal track, a transverse track arranged in the transverse ferry area, and a transverse vehicle arranged on the transverse track and capable of lifting the longitudinal vehicle;

[0020] The longitudinal transfer vehicle is provided with a current collector, and a production area and a second busbar are provided between the transverse transfer ferry areas at both ends. The above-mentioned busbar power supply devices are provided at both ends of the production area. The first busbar is provided on the outer side of one of the longitudinal transfer track and the return track near the transverse transfer ferry area, and the second busbar is provided on the outer side of the other longitudinal transfer track and the return track. Both the first busbar and the second busbar are arranged parallel to the longitudinal transfer track.

[0021] A method for transferring the above-mentioned prefabricated beam production line comprises the following steps:

[0022] S1, the longitudinal transfer vehicle loaded with prefabricated beams moves from the production area to the transverse transfer area, and the second busbar contacts the current collector;

[0023] S2, the longitudinal transfer vehicle is about to enter the transverse transfer area from the production area, and the first busbar extends to the transverse transfer area and contacts the current collector;

[0024] S3, the longitudinal transfer vehicle stops moving after completely entering the transverse transfer area, the first busbar retracts to the production area, and the precast beam is transferred from the longitudinal transfer vehicle to the storage area;

[0025] S4, the transverse transfer vehicle moves to the bottom of the longitudinal transfer vehicle and lifts up the longitudinal transfer vehicle to separate it from the longitudinal transfer track, the transverse transfer vehicle moves along the transverse transfer track, and when the longitudinal transfer vehicle is aligned with the return track, the transverse transfer vehicle lowers the longitudinal transfer vehicle onto the return track;

[0026] S5, the first busbar extends to the transverse ferry area and contacts the current collector, and the longitudinal transfer vehicle enters the production area from the transverse ferry area;

[0027] S6. The longitudinal transfer vehicle completely enters the production area, the first busbar retracts to the production area, and the second busbar contacts the current collector.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] The bus bar power supply device of the present invention has a driving component that can drive the telescopic part to telescope along the length direction of the first bus bar. The first bus bar is connected to the telescopic part, so that the first bus bar also has a telescopic function. When used in a transverse ferrying solution of a jacking-type transverse moving vehicle, when the longitudinal moving vehicle wants to enter the transverse ferrying area or leave the transverse ferrying area, the first bus bar extends to the transverse ferrying area to supply power to the collector on the longitudinal moving vehicle. When the longitudinal moving vehicle wants to move laterally, the first bus bar retracts from the transverse ferrying area to avoid interference. The overall structure is reasonable and the reliability is good.

[0030] The working method of the busbar power supply device of the present invention is that when the longitudinal transfer vehicle wants to enter the transverse transfer ferry area or leave the transverse transfer ferry area, the first busbar extends to the transverse transfer ferry area to supply power to the collector on the longitudinal transfer vehicle, thereby providing continuous power to the longitudinal transfer vehicle; when the longitudinal transfer vehicle wants to move laterally, the first busbar retracts from the transverse transfer ferry area and will not hinder the lateral movement of the longitudinal transfer vehicle in the transverse transfer ferry area.

[0031] In the precast beam production line of the present invention, the longitudinal track is laid to the transverse ferry area, and the transverse ferry area adopts a jacking-type transverse transport vehicle, which avoids the high cost and cumbersome maintenance problems of the solution of digging a foundation pit and setting up a transverse ferry vehicle. When the longitudinal transport vehicle moves longitudinally in the production area, the second busbar can be used to power the collector. When entering the transverse ferry area from the production area or entering the production area from the transverse ferry area, the first busbar can be extended from the production area into the transverse ferry area to continuously supply power to the collector, avoiding the defects of manual plugging, such as plug damage, accidental power failure and poor safety. When the longitudinal transport vehicle needs to move laterally in the transverse ferry area, the first busbar can be retracted from the transverse ferry area to the production area to avoid obstruction. The overall structure is reasonable and the reliability is good.

[0032] The transfer method of the precast beam production line of the present invention is that when the longitudinal transfer vehicle moves longitudinally in the production area, the second busbar is used to supply power to the collector. When entering the transverse ferry area from the production area or entering the production area from the transverse ferry area, the first busbar extends from the production area into the transverse ferry area, thereby continuously supplying power to the collector, thus avoiding the defects of manual plugging, such as plug damage, accidental power failure and poor safety. When the longitudinal transfer vehicle needs to move laterally in the transverse ferry area, the first busbar is retracted from the transverse ferry area to the production area to avoid obstruction. The automation level is high and the operation is smooth.

[0050] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Embodiment 1

[0052] Figures 1 to 3 An embodiment of a busbar power supply device of the present invention is shown. The busbar power supply device of this embodiment includes a bracket 1, a first busbar 2 and a telescopic member 3. The first busbar 2 is connected to the telescopic member 3. The bracket 1 is provided with a driving component 4 for driving the telescopic member 3 to extend and retract along the length direction of the first busbar 2.

[0053] In the busbar power supply device of the present embodiment, the driving component 4 can drive the telescopic part 3 to telescope along the length direction of the first busbar 2. The first busbar 2 is connected to the telescopic part 3, so that the first busbar 2 also has a telescopic function; when used for the transverse ferrying scheme of the jacking-type transverse moving vehicle, when the longitudinal moving vehicle 7 wants to enter the transverse ferrying area 8 or leave the transverse ferrying area 8, the first busbar 2 extends to the transverse ferrying area 8 to supply power to the collector 71 on the longitudinal moving vehicle 7. When the longitudinal moving vehicle 7 wants to move laterally, the first busbar 2 retracts from the transverse ferrying area 8 to avoid interference. The overall structure is reasonable and the reliability is good.

[0054] See Figure 2 In this embodiment, the bracket 1 is provided with a guide assembly 5, which includes a guide tube 51 and guide wheels 52 arranged at both ends of the guide tube 51. The telescopic member 3 is inserted into the guide tube 51, and the guide wheels 52 are arranged at the upper and lower sides of the telescopic member 3. The guide tube 51 cooperates with the guide wheels 52 at both ends to provide a good guiding effect for the telescopic member 3, limiting the telescopic member 3 from moving in the telescopic direction ( Figure 1 and Figure 2 The guide wheel 52 can reduce the frictional resistance between the telescopic member 3 and the telescopic member 3, so that the telescopic movement of the telescopic member 3 is smoother, and the driving power required by the driving assembly 4 can also be appropriately reduced. Of course, in other embodiments, the guide assembly 5 can also adopt a guide rail, a guide groove, and other structural forms.

[0055] Preferably, the telescopic member 3 is a tube, and the cross-sections of the guide tube 51 and the telescopic member 3 are both rectangular structures. The four corners of the rectangle are transitioned through rounded corners. Compared with the commonly used circular tube, it is beneficial to prevent the telescopic member 3 from rotating, and at the same time increase the contact area between the telescopic member 3 and the friction wheel 42, so as to better drive the telescopic member 3 to extend and retract.

[0056] Furthermore, in this embodiment, the first busbar 2 is arranged below the guide tube 51, a lifting assembly 61 for adjusting the height of the first busbar 2 is connected between the telescopic member 3 and the first busbar 2, a notch 53 for the lifting assembly 61 to pass through is provided at the bottom of the guide tube 51, and a translation assembly 11 is provided on the bracket 1, and the translation assembly 11 is used to adjust the position of the bracket 1 along a direction perpendicular to the length direction of the first busbar 2. For details, see Figure 2 , the height of the first busbar 2 can be adjusted by the lifting assembly 61, and the bracket 1 and the guide assembly 5 thereon can be adjusted to move left and right by the translation assembly 11, thereby adjusting the lateral position of the first busbar 2, so that the first busbar 2 can be accurately docked with the collector 71 on the longitudinal moving vehicle 7, further improving the reliability of the device. Preferably, the lifting assembly includes a connecting plate 611 provided on the telescopic member 3 and a connecting screw 612 provided on the first busbar 2, and the upper end of the connecting screw 612 passes through the connecting plate 611 and is locked by nuts provided on the upper and lower sides of the connecting plate 611, and has good reliability. After loosening the nut, the first busbar 2 can be driven to move up and down by connecting the screw 612, which is easy to operate; the bracket 1 includes a pillar 12 and a base plate 13 arranged at the bottom of the pillar 12, and the translation component 11 includes a transverse waist-shaped hole arranged on the base plate 13 and a threaded fastener (such as embedded bolts, screws, etc.) passing through the transverse waist-shaped hole. The base plate 13 is fixed to the ground by threaded fasteners, and the lateral position of the bracket 1, the guide component 5, the telescopic member 3 and the first busbar 2 can be conveniently adjusted as a whole.

[0057] In this embodiment, the driving assembly 4 includes a motor 41 and a friction wheel 42. The friction wheel 42 is arranged on the output shaft of the motor 41, and the telescopic member 3 contacts the friction wheel 42. When the first busbar 2 needs to be extended, the motor 41 is started to drive the friction wheel 42 to rotate. The friction wheel 42 drives the telescopic member 3 to move back and forth in the guide tube 51 through friction. The first busbar 2 moves back and forth with the telescopic member 3. The structure is simple and compact, and it takes up little space. Of course, in other embodiments, the telescopic member 3 can also be driven to move back and forth by means of a gear rack, a cylinder, an oil cylinder or a push rod.

[0058] In this embodiment, the busbar power supply device also includes a limit assembly 62 for limiting the telescopic travel of the telescopic member 3. Preferably, the limit assembly 62 is a rotary encoder provided on the output shaft of the motor 41, which controls the number of revolutions or angles of the motor 41, thereby controlling the extension amount of the telescopic member 3 to prevent the telescopic member 3 from exceeding the travel range, and has a simple and reliable structure. Of course, in other embodiments, the limit assembly 62 may also include an induction switch provided on the guide tube 51 and a trigger head provided at both ends of the telescopic member 3, or limit buffer blocks may be provided at both ends of the guide tube 51 for mechanical limiting, etc.

[0059] See Figure 1 and Figure 2 In this embodiment, the rear end of the telescopic member 3 in the telescopic direction (the telescopic member 3 extends to the right, and accordingly, the left end of the telescopic member 3 is the rear end) is connected to a drag chain 31, and the wiring harness can be passed through the drag chain 31, thereby standardizing the wiring and preventing the wiring harness from hanging on the longitudinal moving vehicle 7.

[0060] See Figure 2 In this embodiment, a trigger assembly for controlling the extension and retraction of the first busbar 2 is provided between the guide assembly 5 on the bracket 1 and the longitudinal transfer vehicle 7. Preferably, the trigger assembly includes a position sensor 54 provided on the guide tube 51 and a position sensor trigger plate 76 provided on the longitudinal transfer vehicle 7. Figures 6 to 9 The longitudinal transfer vehicle 7 moves longitudinally. When the position sensor 54 detects the position sensor trigger plate 76, the first busbar 2 extends to supply power to the collector 71 on the longitudinal transfer vehicle 7. The longitudinal transfer vehicle 7 can continue to move longitudinally and smoothly enter the transverse ferry area 8, further improving the automation and intelligence of the system.

[0061] Embodiment 2

[0062] The working method of the busbar power supply device of this embodiment as described above,

[0063] When the longitudinal transfer vehicle 7 intends to enter the transverse transfer ferry area 8 or leave the transverse transfer ferry area 8, the driving assembly 4 drives the telescopic member 3 to extend, and the telescopic member 3 drives the first busbar 2 to extend to the transverse transfer ferry area 8 to supply power to the collector 71 on the longitudinal transfer vehicle 7;

[0064] When the longitudinal transfer vehicle 7 is to move transversely in the transverse transfer ferry area 8 , the driving assembly 4 drives the telescopic member 3 to retract, and the telescopic member 3 drives the first busbar 2 to retract from the transverse transfer ferry area 8 .

[0065] The working method of the busbar power supply device of the present embodiment is that when the longitudinal moving vehicle 7 wants to enter the transverse moving ferry area 8 or leave the transverse moving ferry area 8, the first busbar 2 extends to the transverse moving ferry area 8 to supply power to the collector 71 on the longitudinal moving vehicle 7, thereby providing continuous power to the longitudinal moving vehicle 7. When the longitudinal moving vehicle 7 wants to move laterally, the first busbar 2 retracts from the transverse moving ferry area 8 and will not hinder the lateral movement of the longitudinal moving vehicle 8 in the transverse moving ferry area 8.

[0066] Embodiment 3

[0067] Figures 4 to 11 An embodiment of the precast beam production line of the present invention is shown. The precast beam production line of this embodiment includes a longitudinal track 72, a return track 75 arranged parallel to the longitudinal track 72, a longitudinal vehicle 7 arranged on the longitudinal track 72, a transverse ferry area 8 arranged at both ends of the longitudinal track 72, a transverse track 81 arranged in the transverse ferry area 8, and a transverse vehicle 82 arranged on the transverse track 81 and capable of lifting the longitudinal vehicle 7;

[0068] A current collector 71 is provided on the longitudinal transfer vehicle 7, and a production area 73 (i.e., prefabricated beams 93 are produced in this area) and a second busbar 74 are provided between the transverse transfer ferry areas 8 at both ends. The above-mentioned busbar power supply devices are provided at both ends of the production area 73, and a first busbar 2 is provided on the outer side of one longitudinal transfer track 72 and the return track 75 near the transverse transfer ferry area 8, and a second busbar 74 is provided on the outer side of the other longitudinal transfer track 72 and the return track 75. Both the first busbar 2 and the second busbar 74 are arranged parallel to the longitudinal transfer track 72.

[0069] In the precast beam production line of this embodiment, the longitudinal track 72 is laid to the transverse ferry area 8. The transverse ferry area 8 adopts a jacking transverse vehicle, which avoids the high cost and cumbersome maintenance problems of digging foundation pits and setting up transverse ferry vehicles. When the longitudinal vehicle 7 moves longitudinally in the production area 73, the second busbar 74 can be used to supply power to the collector 71. When entering the transverse ferry area 8 from the production area 73 or entering the production area 73 from the transverse ferry area 8, the first busbar 2 can extend from the production area 73 into the transverse ferry area 8 to continuously supply power to the collector 71, avoiding the defects of manual plugging, such as plug damage, accidental power failure and poor safety. When the longitudinal vehicle 7 needs to move laterally in the transverse ferry area 8, the first busbar 2 can be retracted from the transverse ferry area 8 to the production area 73 to avoid obstruction. The overall structure is reasonable and the reliability is good. See for details. Figure 5The longitudinal track 72 is located between the first busbar 2 and the second busbar 74, which can prevent the second busbar 74 from affecting the telescopic movement of the first busbar 2. Accordingly, collectors 71 are provided on both sides of the longitudinal vehicle 7, which are respectively connected to the first busbar 2 and the second busbar 74; see Fig.10 The second busbar 74 is also hoisted by connecting the screw rod 612, which is convenient for adjusting the height, but does not require telescopic movement. Therefore, the installation structure is simplified compared to the first busbar 2, which can save costs.

[0070] Furthermore, in this embodiment, the prefabricated beam production line also includes a lifting track 9 arranged in the transverse direction and a lifting device 91 (such as a beam lifting gantry crane) arranged on the lifting track 9. One end of the lifting track 9 extends to the transverse ferry area 8, and the other end of the lifting track 9 is provided with a storage area 92. The lifting device 91 moves back and forth along the lifting track 9, and can lift the prefabricated beam 93 transferred from the longitudinal transfer vehicle 7 to the transverse ferry area 8 to the storage area 92 for storage. After unloading, the longitudinal transfer vehicle 7 can return to the production area 73 through the two transverse ferry areas 8 and the return track 75.

[0071] Embodiment 4

[0072] The transfer method of the prefabricated beam production line of this embodiment includes the following steps:

[0073] S1, the longitudinal transfer vehicle 7 loaded with prefabricated beams 93 moves from the production area 73 to the transverse transfer ferry area 8 provided with the lifting rail 9 (see Figure 4 , in this embodiment, it moves from right to left), the second busbar 74 contacts the collector 71, that is, the longitudinal moving vehicle 7 is powered by the second busbar 74;

[0074] S2, the longitudinal transfer vehicle 7 wants to enter the transverse transfer ferry area 8 from the production area 73, and the first busbar 2 extends to the transverse transfer ferry area 8 (specifically, when the position sensor 54 detects the position sensor trigger plate 76, the first busbar 2 extends to the transverse transfer ferry area 8) and contacts the collector 71, that is, the longitudinal transfer vehicle 7 is powered by the first busbar 2;

[0075] S3, the longitudinal transfer vehicle 7 stops moving after completely entering the transverse transfer ferry area 8, the first busbar 2 retracts to the production area 73, and the lifting equipment 91 lifts the precast beam 93 from the longitudinal transfer vehicle 7 to the storage area 92;

[0076] S4, the transverse transfer vehicle 82 moves to the bottom of the longitudinal transfer vehicle 7 and lifts up the longitudinal transfer vehicle 7 and separates it from the longitudinal transfer track 72 (as shown in the figure below). Fig.11 As shown, the longitudinal transfer vehicle 7 can be lifted up by a hydraulic cylinder, a jack, etc.), and the transverse transfer vehicle 82 moves along the transverse transfer track 81. When the longitudinal transfer vehicle 7 is aligned with the return track 75, the transverse transfer vehicle 82 lowers the longitudinal transfer vehicle 7 onto the return track 75;

[0077] S5, the first busbar 2 extends to the transverse ferry area 8 and contacts the current collector 71, that is, the first busbar 2 supplies power to the longitudinal transfer vehicle 7, and the longitudinal transfer vehicle 7 enters the production area 73 from the transverse ferry area 8, that is, moves from left to right;

[0078] S6, the longitudinal transfer vehicle 7 completely enters the production area 73, the first busbar 2 retracts to the production area 73, and the second busbar 74 contacts the collector 71, that is, the longitudinal transfer vehicle 7 is powered by the second busbar 74. The subsequent longitudinal transfer vehicle 7 enters the right transverse ferry area 8 from the production area 73 again and returns to the production area 73 from the right transverse ferry area 8. The process is the same as steps S2 to S6 (but no longer involves the lifting equipment 91 lifting the precast beam 93), which will not be repeated.

[0079] In the transfer method of the prefabricated beam production line of this embodiment, when the longitudinal transfer vehicle 7 moves longitudinally in the production area 73, the second busbar 74 supplies power to the collector 71. When entering the transverse ferry area 8 from the production area 73 or entering the production area 73 from the transverse ferry area 8, the first busbar 2 extends from the production area 73 into the transverse ferry area 8, thereby continuously supplying power to the collector 71, avoiding the defects of manual plugging, such as plug damage, accidental power outages and poor safety. When the longitudinal transfer vehicle 7 moves laterally in the transverse ferry area 8, the first busbar 2 retracts from the transverse ferry area 8 to the production area 73 to avoid obstruction. The automation level is high and the operation is smooth.
