Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering machinery, in particular to a ring rail crane transfer device and a ring rail crane site transfer method. BACKGROUND

[0002] The ring rail crane is a large-scale boom crane that runs on a fixed ring rail. Its core feature is to realize the rotation movement through the ring rail, and it has super lifting capacity and high stability. However, due to the dependence of the ring rail crane on the rail, when the ring rail crane needs to be used in other construction sites, the ring rail crane in the current site needs to be transferred to other construction sites. The conventional transfer method is to disassemble the ring rail crane and then transfer it, which is time-consuming and laborious.

[0003] Another existing transfer method is to use multiple self-propelled flat cars (SPMT) to directly lift the ring rail crane for transfer. However, the bearing surface of the self-propelled flat car is directly pressed on the part of the bearing surface of the self-propelled flat car when lifting the lifted part of the ring rail crane, so that the effective bearing area of the bearing surface is small, which causes the self-propelled flat car to be easily damaged due to stress concentration.

[0004] Therefore, how to solve or improve the problem that the effective bearing area of the bearing surface is small when using the self-propelled flat car to transfer the ring rail crane, which causes the self-propelled flat car to be easily damaged, has become an important technical problem for technicians in the field to solve.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0046] The embodiments of the present application will be described below in combination with Figures 1 to 5 The embodiments of the present application will be described below in combination with

[0047] According to the embodiments of the present application, on the one hand, a loop track crane transfer device is provided, such as Figure 1As shown, it comprises a flatbed truck 1, a support 3, a lifting device 4 and a carrier 5. The flatbed truck 1 has a top with a carrying surface, and the flatbed truck 1 can be moved arbitrarily.

[0048] The bottom of the support 3 is connected with the carrying surface, and the size of the support 3 in the first direction X gradually increases from top to bottom. That is, the support 3 is widened from top to bottom, and the size of the bottom of the support 3 is larger than that of the top.

[0049] The top of the carrier 5 is used to carry heavy objects, and the bottom of the carrier 5 is connected with the lifting device 4, so that the carrier 5 can be driven to rise and fall by using the lifting device 4. The lifting device 4 is connected to the top of the support 3. When the carrier 5 carries heavy objects, the gravity of the heavy objects is transmitted to the carrying surface through the support 3. Since the size of the bottom of the support 3 is larger than that of the top, the acting surface of the force is larger when the force is transmitted to the carrying surface, and the force can be transmitted to a larger area of the carrying surface.

[0050] When the ring rail crane 9 is transported by using the ring rail crane transport device, as shown in Figure 4 and Figure 5 A plurality of ring rail crane transport devices are prepared, and the carrier 5 on each flatbed truck 1 is lowered by using the lifting device 4 respectively, so that the carrier 5 on each flatbed truck 1 is lower than the lifted place of the ring rail crane 9.

[0051] Then each flatbed truck 1 is moved to below the ring rail crane 9, so that the carrier 5 on each flatbed truck 1 is respectively below the lifted place of a ring rail crane 9.

[0052] Then the carrier 5 on each flatbed truck 1 is raised by using the lifting device 4 respectively, so that the carrier 5 on each flatbed truck 1 is raised to the lifted place of the ring rail crane 9 and continues to rise until the ring rail crane 9 is lifted and the ring rail crane 9 is separated from the slide rail.

[0053] Then each flatbed truck 1 is moved simultaneously, so that the ring rail crane 9 is transported to other places, and the ring rail crane 9 is located above the slide rail in other places.

[0054] Then the carrier 5 on each flatbed truck 1 is lowered by using the lifting device 4 respectively, so that the ring rail crane 9 is lowered and connected to the slide rail, and then the carrier 5 continues to be lowered, so that the carrier 5 on each flatbed truck 1 is away from the ring rail crane 9, and finally each flatbed truck 1 is moved to leave below the ring rail crane 9, so that the transportation of the ring rail crane 9 is completed.

[0055] In the process of transporting the loop track crane 9, the loop track crane 9 is carried by the carrier 5, and then the pressure is conducted to the carrying surface of the flat transport vehicle 1 through the support 3. Because the size of the bottom of the support 3 is larger than the size of the top, compared with the loop track crane 9 directly carried by the carrying surface of the flat transport vehicle 1, under the conducting action of the support 3, the effective carrying area of the carrying surface of the flat transport vehicle 1 to the loop track crane 9 is larger, so that the gravity of the loop track crane 9 is dispersed to a larger area of the carrying surface of the flat transport vehicle 1, so as to reduce the carrying pressure of each position on the flat transport vehicle 1 and reduce the risk of damage of the flat transport vehicle 1.

[0056] The lifting device 4 can be a lead screw mechanism or a hydraulic cylinder.

[0057] The carrier 5 can be plate-shaped or disc-shaped.

[0058] As an optional embodiment, as shown in Figure 1 The support 3 is provided with a plurality of supports 3, and the bottoms of the supports 3 are connected to the carrying surface respectively, so that the carrying surface of the flat transport vehicle 1 carries all the supports 3 at the same time. The lifting device 4 is connected to each support 3, and the carrier 5 connected to each lifting device 4 is used to carry the heavy object. The lifting device 4 is a piston cylinder, the rod cavities of the piston cylinders are connected to each other, and the rodless cavities of the piston cylinders are connected to each other. In this way, the piston cylinders are connected in parallel, so that the piston rods of the piston cylinders can move and carry at the same time, that is, the lifting devices 4 can act synchronously.

[0059] The piston cylinder can be a hydraulic cylinder or an air cylinder.

[0060] Taking the hydraulic cylinder as an example, as shown in Figure 1 A pump station 2 is arranged on the flat transport vehicle 1, and the pump station 2 has two oil ports. The two oil ports are a first oil port and a second oil port respectively. When one of the two oil ports is filled with oil, the other oil port discharges oil. The first oil port is connected to the rod cavity of any piston cylinder through a pipeline, and the second oil port is connected to the rodless cavity of any piston cylinder through a pipeline.

[0061] In this way, when the pump station 2 discharges oil from the first oil port, the oil enters the rod cavity of one piston cylinder. Because the rod cavities of the piston cylinders are connected to each other, the oil can enter the rod cavities of all the piston cylinders at the same time, and then push the piston rods to retract at the same time, so that the carrier 5 descends. At this time, the rodless cavities of the piston cylinders are compressed by the piston. Because the rodless cavities of the piston rods are connected to each other, the oil flows out of the rodless cavities of the piston cylinders and then returns to the pump station 2 through the second oil port at the same time.

[0062] When pump station 2 discharges oil from the second oil port, the oil enters the rodless chamber of a piston cylinder. Since the rodless chambers of each piston cylinder are interconnected, the oil can enter the rodless chambers of all piston cylinders at the same time, thereby simultaneously pushing the piston rod to extend, causing the bearing 5 to rise. At this time, the rod chamber of the piston cylinder is compressed by the piston. Since the rod chambers of each piston rod are interconnected, the oil flows out from the rod chambers of each piston cylinder and simultaneously returns to pump station 2 through the second oil port.

[0063] Specifically, during the transfer of the ring rail crane 9, for each ring rail crane transfer device, the first oil inlet of the pump station 2 and the second oil outlet are operated to simultaneously lower each load-bearing component 5. After the flatbed transport vehicle 1 is moved below the ring rail crane 9, each load-bearing component 5 is positioned below a corresponding lifted point of the ring rail crane 9. At this time, the second oil inlet of the pump station 2 and the first oil outlet are operated to simultaneously raise each load-bearing component 5 until the ring rail crane 9 is lifted and disengaged from the slide rail.

[0064] At this point, since the rod chambers of each piston cylinder are interconnected, and the rodless chambers of each piston rod are interconnected, when the gravity of the ring crane 9 acts on the piston rod of each piston cylinder, the hydraulic oil evenly distributes the gravity of the ring crane 9 to each cylinder, so that each piston cylinder bears the same component of force, that is, each support 3 bears the same component of force. Therefore, the pressure on the bearing surface at the bottom of each support 3 is the same.

[0065] This configuration ensures that although the actual downward force generated at each lifting point of the ring crane 9 is different, the force on each hydraulic cylinder is the same due to the diversion of hydraulic oil. This results in the same pressure being exerted on each bearing position on the flatbed transport vehicle 1, preventing excessive pressure at any particular bearing position from damaging the flatbed transport vehicle 1.

[0066] As an optional embodiment, such as Figure 1 As shown, at least two lifting devices 4 are connected to the support 3. Each lifting device 4 is connected to a bearing member 5 and is used to drive the bearing member 5 to rise and fall. The lifting device 4 is configured as a piston cylinder, with the rod chambers of each piston cylinder interconnected and the rodless chambers of each piston cylinder interconnected. This configuration allows the piston cylinders to be connected in parallel, enabling the piston rods of each piston cylinder to move and bear load simultaneously, that is, the lifting devices 4 can operate synchronously.

[0067] This configuration allows for simultaneous lowering of all support components 5 during the transfer of the ring rail crane 9. After the flatbed transport vehicle 1 is moved below the ring rail crane 9, each support component 5 is positioned below a corresponding lifted section of the ring rail crane 9. Simultaneously, all support components 5 are raised until the ring rail crane 9 is lifted and disengaged from the slide rail. The multiple support components 5 simultaneously support the ring rail crane 9, resulting in more stable and reliable support.

[0068] As an optional embodiment, as shown in Figure 1 and Figure 2 The ring rail crane transfer device further comprises a connecting plate 7, one side of the connecting plate 7 is connected to the bearing surface, and the bottom of the support 3 is connected to the side of the connecting plate 7 away from the bearing surface.

[0069] In this way, when the bearing 5 lifts the ring rail crane 9, the gravity of the ring rail crane 9 is sequentially transmitted downward through the bearing 5, the lifting device 4 and the support 3. Since the bottom of the support 3 is connected to the side of the connecting plate 7 away from the bearing surface, the force transmitted to the support 3 is conducted through the support 3 and then transmitted to the connecting plate 7, and then transmitted to the bearing surface. At this time, the force transmitted by the support 3 to the connecting plate 7 is dispersed to all parts of the connecting plate 7, and then transmitted to the bearing surface in a face-to-face contact manner, so that the force borne by the part of the bearing surface connected to the connecting plate 7 is more evenly dispersed, further reducing the risk of damage to the flatbed transport vehicle 1 caused by pressure concentration.

[0070] The size of the bearing surface is greater than the size of the bottom of the support 3.

[0071] As an optional embodiment, as shown in Figure 1 and Figure 2 The support 3 comprises a first cross bar 11, a second cross bar 12, a first support bar 13 and a second support bar 14.

[0072] The first cross bar 11 is arranged along the first direction X, the second cross bar 12 is also arranged along the first direction X and located above the first cross bar 11, and the length of the second cross bar 12 is shorter than that of the first cross bar 11. In the first direction X, both ends of the second cross bar 12 extend beyond both sides of the lifting device 4, and both ends of the first cross bar 11 extend beyond both ends of the second cross bar 12.

[0073] The first support bar 13 is arranged in multiple, and each support bar is connected between the first cross bar 11 and the second cross bar 12, so as to connect the second cross bar 12 to the first cross bar 11 through each first support bar 13.

[0074] The second support bar 14 is arranged in multiple, each second support bar 14 has a first end and a second end, the first end of each second support bar 14 is connected to the side of the second cross bar 12 away from the first support bar 13, and the second end of each second support bar 14 is connected to the bottom of the lifting device 4.

[0075] In this way, the second support bar 14, the second cross bar 12, the first support bar 13 and the first cross bar 11 are sequentially connected from top to bottom to form the support 3, and in the first direction X, the size of the top of the support 3 is smaller than the size of the bottom of the support 3.

[0076] In some embodiments, each of the first support rods 13 and the second support rods 14 are arranged to be inclined relative to the vertical direction, and the at least two first support rods 13 are arranged to be inclined in opposite directions, and the at least two second support rods 14 are arranged to be inclined in opposite directions, so that the support frame 3 as a whole forms a plurality of triangular structures or trapezoidal structures, so that the overall structure of the support frame 3 is more stable.

[0077] As an optional embodiment, as shown in Figure 1 and Figure 2 , the ring rail crane transfer device further comprises a mounting plate 6. The lifting device 4 is connected to the top of the mounting plate 6, and the bottom of the mounting plate 6 is connected to the top of the support frame 3.

[0078] For the connection of the lifting device 4 and the support frame 3, the top of the support frame 3 is fixedly connected to the bottom of the mounting plate 6, and at this time the top of the mounting plate 6 forms a mounting surface, and the lifting device 4 is connected to the mounting surface on the mounting plate 6, so that the lifting device 4 is connected to the top of the support frame 3, and the connection is more convenient.

[0079] A plurality of connection portions are arranged on the bottom of the mounting plate 6, and the second end of each second support rod 14 is connected to each connection portion on the bottom of the mounting plate 6 one by one, so that each second support rod 14 is connected to the bottom of the mounting plate 6, respectively.

[0080] In some embodiments, a first flange plate can be fixedly arranged on the mounting surface of the mounting plate 6, and a second flange plate can be fixedly arranged at the bottom of the lifting device 4. The first flange plate and the second flange plate cooperate with each other. After the first flange plate and the second flange plate are aligned, the first flange plate and the second flange plate are fixedly connected by using bolts, so that the lifting device 4 is connected to the mounting surface on the mounting plate 6. In this way, not only is the installation convenient, but also the disassembly is more convenient.

[0081] In an optional embodiment, as shown in Figure 1 and Figure 2 , the ring rail crane transfer device further comprises a first connecting rod 15 and a second connecting rod 16. The first cross rod 11 is provided in at least two, and adjacent two first cross rods 11 are connected by the first connecting rod 15. The second cross rod 12 is provided in at least two, and adjacent two second cross rods 12 are connected by the first connecting rod 15. In this way, the first cross rod 11, the first connecting rod 15, the second cross rod 12, the second connecting rod 16 and the first support rod 13 are connected to each other in a frame shape, and the whole is more stable.

[0082] Specifically, each of the first cross rods 11 is located in the same horizontal plane, and each of the first cross rods 11 is connected to the bearing surface of the flatbed transport vehicle 1. For adjacent two first cross rods 11, one end of the first connecting rod 15 is connected to one first cross rod 11, and the other end is connected to the other first cross rod 11, so as to connect the adjacent two first cross rods 11 by the first connecting rod 15, thereby increasing the stability.

[0083] The top of each first horizontal rod 11 is connected with a second horizontal rod 12 through a first support rod 13. Each second horizontal rod 12 is located in the same horizontal plane, and each second horizontal rod 12 is connected with the bottom of the lifting device 4 through a second support rod 14. For two adjacent second horizontal rods 12, one end of a second connecting rod 16 is connected with one second horizontal rod 12, and the other end is connected with the other second horizontal rod 12, so as to connect the two adjacent second horizontal rods 12 through the second connecting rod 16 and increase the stability.

[0084] In other optional embodiments, the ring rail crane transfer device further comprises a plurality of outriggers 17, each outrigger 17 having a first end and a second end, the first end of each outrigger 17 being connected with the bottom of the first horizontal rod 11, and the second end of each outrigger 17 being connected with the bearing surface to increase the stability.

[0085] In the above embodiments, each outrigger 17 is inclined relative to the vertical direction, and the inclination directions of at least two outriggers 17 are opposite, so that a triangular structure or a trapezoidal structure is formed between the first horizontal rod 11 and the two outriggers 17, and the structure is more stable.

[0086] When the ring rail crane 9 is carried by the bearing member 5, the gravity of the ring rail crane 9 is first transmitted to the lifting device 4, then dispersed to the plurality of second support rods 14, then transmitted to the second horizontal rods 12, then dispersed to the plurality of first support rods 13, then transmitted to the first horizontal rod 11, then dispersed to the plurality of outriggers 17, and finally transmitted to the bearing surface of the flatbed transport vehicle 1 after the gravity is dispersed through multiple stages, so that the dispersion effect is better and the gravity dispersion is more uniform.

[0087] In some combined embodiments, one side of the connecting plate 7 is connected to the bearing surface of the flatbed transport vehicle 1, and the second end of each outrigger 17 is connected with the side of the connecting plate 7 away from the bearing surface. In this way, the pressure conducted through the support 3 is pressed on the connecting plate 7 through each outrigger 17, and is dispersed to all parts of the connecting plate 7, and then is transmitted to the bearing surface in a surface-to-surface contact manner, so that the force borne by the part of the bearing surface connected with the connecting plate 7 is more evenly dispersed. The outriggers 17 are directly connected with the bearing surface in a small contact area.

[0088] As an optional embodiment, as shown in Figure 1 and Figure 2As shown, the loop-track crane transfer device further comprises a blocking piece 8, which can be connected to the flat transport vehicle 1, the support 3, the lifting device 4 or the bearing plate. In the moving direction of the flat transport vehicle 1, the blocking piece 8 should be located at the front side. When the flat transport vehicle 1 moves, the blocking piece 8 just limits the cooperation with the preset blocking part on the loop-track crane 9 in the moving direction of the flat transport vehicle 1, so that the blocking piece 8 can push the heavy object to move when the flat transport vehicle 1 moves, avoiding the heavy object from separating from the loop-track crane transfer device.

[0089] Specifically, when the loop-track crane 9 is transferred, the loop-track crane 9 is preset with a blocking part, which abuts against the bearing part and the lifted part of the loop-track crane 9, and lifts the loop-track crane 9. At this time, the blocking piece 8 just limits the cooperation with the blocking part in the moving direction of the flat transport vehicle 1. When the flat transport vehicle 1 moves, the loop-track crane 9 and the loop-track crane transfer device are not only relatively fixed by the friction force between the loop-track crane 9 and the bearing piece 5, but also pushed to move together with the flat transport vehicle 1 by the limiting cooperation between the blocking piece 8 and the blocking part.

[0090] The blocking piece 8 can be a protruding block.

[0091] In some embodiments, as shown in Figure 1 and Figure 2 The lifting device 4 is connected to the top of the mounting plate 6, the bottom of the mounting plate 6 is connected to the top of the support 3, the blocking piece 8 is connected to the top of the mounting plate 6 and extends out of the mounting plate 6 in the moving direction of the flat transport vehicle 1.

[0092] According to the embodiments of the present application, in another aspect, a loop-track crane transfer method is also provided, which is suitable for any of the loop-track crane transfer devices described above, as shown in Figure 4 and Figure 5 The method comprises the following steps:

[0093] S1, lower the bearing piece 5 of each loop-track crane transfer device, and drive each flat transport vehicle 1 to move until each bearing piece 5 is located below the loop-track crane 9;

[0094] S2, raise the bearing piece 5 of each loop-track crane transfer device until each bearing piece 5 collectively lifts the loop-track crane 9 away from the current slide rail;

[0095] S3, drive each flat transport vehicle 1 to move until the loop-track crane 9 is located above the target slide rail;

[0096] S4, lower each bearing piece 5 so that the loop-track crane 9 is connected to the target slide rail.

[0097] Specifically, at least two loop-track crane transfer devices are prepared, and the lifting devices 4 are used to respectively lower the load carriers 5 on the flatbed transporters 1, so that the load carriers 5 on the flatbed transporters 1 are lower than the lifted positions of the loop-track cranes 9. Then the flatbed transporters 1 are respectively driven to move so that the flatbed transporters 1 move to below the loop-track cranes 9, and the load carriers 5 on the flatbed transporters 1 are respectively located below the lifted positions of one loop-track crane 9.

[0098] The lifting devices 4 are used to respectively lift the load carriers 5 on the flatbed transporters 1, so that the load carriers 5 on the flatbed transporters 1 are lifted to abut the lifted positions of the loop-track cranes 9 and continue to be lifted until the loop-track cranes 9 are lifted and the loop-track cranes 9 are separated from the current rails.

[0099] The flatbed transporters 1 are simultaneously driven to move, so that the loop-track cranes 9 are transferred to other sites, and the loop-track cranes 9 are located above the target rails of the other sites.

[0100] Then the lifting devices 4 are used to respectively lower the load carriers 5 on the flatbed transporters 1, so that the loop-track cranes 9 are lowered and connected to the target rails, and then the load carriers 5 continue to be lowered, so that the load carriers 5 on the flatbed transporters 1 are all away from the loop-track cranes 9, and finally the flatbed transporters 1 are moved to be away from below the loop-track cranes 9, so that the transfer of the loop-track cranes 9 is completed.

[0101] During the transfer of the loop-track cranes 9, the loop-track cranes 9 are carried by the load carriers 5, and then the pressure is conducted to the load bearing surfaces of the flatbed transporters 1 through the supports 3. Since the size of the bottom of the support 3 is larger than the size of the top, compared with the loop-track cranes 9 being directly carried by the load bearing surfaces of the flatbed transporters 1, under the conducting action of the support 3, the effective load bearing area of the load bearing surfaces of the flatbed transporters 1 to the loop-track cranes 9 is larger, so that the gravity of the loop-track cranes 9 is dispersed to a larger area of the load bearing surfaces of the flatbed transporters 1, so as to reduce the load bearing pressure of the flatbed transporters 1 and reduce the risk of damage of the flatbed transporters 1.

[0102] Wherein the current rails refer to the rails of the current site to which the loop-track cranes 9 are connected before the transfer, and the target rails refer to the rails of other sites to which the loop-track cranes 9 need to be connected after the transfer.

[0103] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
