Description

Technical Field

[0001] The utility model relates to the technical field of automatic guided vehicles, in particular to a wire vehicle transporting device. Background Art

[0002] For example, the invention patent with announcement number CN103395437B discloses a wire transport vehicle, which includes a vehicle base, a support frame, a plurality of hanging rod assemblies, and running wheels. The support frame is vertically fixed to the vehicle base, the hanging rod assembly is fixed to the support frame and is used to hang the silk cake, and the running wheels are installed under the vehicle base. The wire transport vehicle provided by the present invention is used to transport the silk cake from one process to the next process. After the previous process, the silk cake is directly hung on the hanging rod assembly of the wire transport vehicle, and then the wire transport vehicle is moved to the position of the next process by relying on the running wheels, without the need to remove the silk cake from the wire transport vehicle. Since the silk cake has been hung, the wire transport vehicle can be used as part of the equipment for the next process, and the operation of the next process on the silk cake is performed directly on the wire transport vehicle. Therefore, the complicated operation process of unloading the silk cake from the ordinary transport vehicle and then hanging it on the special equipment for the next process in the prior art is eliminated, saving time and manpower.

[0003] The above-mentioned wire transport vehicles are usually transported manually or by traditional forklifts, which is not only inefficient and inflexible, but also creates a harsh workshop environment that affects the health of workers, so there is still room for improvement. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a wire cart handling device, which transports the wire cart by an automatic guided vehicle, thereby realizing unmanned transportation of the wire cart and improving scheduling flexibility, thereby improving work efficiency and reducing the harm of the workshop environment to workers' health.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A wire car handling device includes an automatic guided vehicle, wherein a locking hook mechanism and a driving mechanism connected to the locking hook mechanism are provided on the front side of the automatic guided vehicle;

[0007] When the automatic guided vehicle runs to the front side of the wire transport vehicle, the driving mechanism drives the locking hook mechanism to rotate forward so that the locking hook mechanism can hook the horizontal bar on the front side of the wire transport vehicle, thereby completing the connection between the automatic guided vehicle and the wire transport vehicle, and then the automatic guided vehicle can drag the wire transport vehicle;

[0008] When the driving mechanism drives the locking hook mechanism to rotate backward, the locking hook mechanism can be separated from the horizontal bar on the front side of the wire transport vehicle, thereby completing the separation of the automatic guided vehicle and the wire transport vehicle.

[0009] The above solution, using an automated guided vehicle (AGV) as a carrier to transport the wire cart, enables unmanned operations within the wire-carrying yard. This not only reduces worker workload but also effectively improves work efficiency while also reducing the impact of the harsh workshop environment on worker health. The drive mechanism activates the locking hook mechanism to achieve stable connection and rapid separation between the AGV and the wire cart, thereby ensuring normal handling of the wire cart.

[0010] Preferably, the locking hook mechanism includes a driving block connected to the driving mechanism, a first positioning portion and a second positioning portion arranged on the driving block. When the driving mechanism drives the locking hook mechanism to hook the horizontal bar on the front side of the wire transport vehicle, the driving block can drive the first positioning portion to buckle onto the side of the horizontal bar away from the automatic guided vehicle, and at the same time drive the second positioning portion to press the upper surface of the horizontal bar.

[0011] By adopting the above solution, the cooperation between the first positioning part and the second positioning part can improve the stability of the locking hook mechanism after hooking the horizontal bar, thereby further improving the stability after the automatic guided vehicle and the wire transport vehicle are connected.

[0012] Preferably, a first pressure wheel is provided on the first positioning portion, and an outer peripheral surface of the first pressure wheel is used to abut against the side of the cross bar away from the automatic guided vehicle.

[0013] By adopting the above solution, the first pressure wheel can convert the sliding friction between the first positioning part and the horizontal bar into rolling friction, thereby improving the smoothness of the docking and separation of the first positioning part and the horizontal bar, and can effectively reduce the wear during the relative movement between the two.

[0014] Preferably, a second pressing wheel is provided on the second positioning portion, and the outer peripheral surface of the second pressing wheel is used to abut against the upper surface of the cross bar.

[0015] By adopting the above solution, the second pressure wheel can convert the sliding friction between the second positioning part and the horizontal bar into rolling friction, thereby improving the smoothness of the docking and separation of the second positioning part and the horizontal bar, and can effectively reduce the wear between the two during relative movement.

[0016] Preferably, two groups of locking hook mechanisms are provided and arranged in a horizontal direction.

[0017] By adopting the above solution, the two sets of locking hook mechanisms can form two force points on the horizontal bar, thereby ensuring the stability of the automatic guided vehicle when transporting the wire cart.

[0018] Preferably, the driving mechanism includes a driving shaft connected to the driving block and rotatably disposed on the front side of the automatic guided vehicle, and a driving portion connected to the driving shaft to drive the driving shaft to rotate.

[0019] Preferably, the driving part is a worm gear reduction motor.

[0020] By adopting the above solution, the driving mechanism can drive the lock hook mechanism to operate stably, thereby improving the efficiency and accuracy of the docking between the lock hook mechanism and the horizontal bar.

[0021] Preferably, the front side of the automatic guided vehicle is provided with at least one set of shock absorbing mechanisms for abutting against the horizontal bars on the front side of the wire transport vehicle to cushion the horizontal bars.

[0022] With this solution, when the AGV and the wire carrier are docked, the shock-absorbing mechanism will preferentially rest against the wire carrier's crossbar and provide a cushioning effect. This not only enables the wire carrier to be pre-positioned, thereby improving docking accuracy, but also protects the wire carrier.

[0023] Preferably, the shock absorbing mechanism includes a shock absorbing block provided at the front side of the automatic guided vehicle and used to abut against the side of the cross bar, and an elastic driving component is provided between the shock absorbing block and the front side of the automatic guided vehicle to make the shock absorbing block have a tendency to move away from the automatic guided vehicle.

[0024] By adopting the above solution, the shock absorbing block has a certain hardness, which can provide better pre-positioning effect for the cross bar of the wire transport vehicle. The elastic drive component can provide lateral elastic support for the shock absorbing block, thereby ensuring that the shock absorbing mechanism has a shock absorbing effect.

[0025] Preferably, the elastic drive assembly includes a base arranged on the front side of the automatic guided vehicle, and a mounting seat arranged on the side of the shock-absorbing block close to the automatic guided vehicle, and at least one guide spring is arranged between the base and the mounting seat so that the mounting seat has a tendency to move laterally away from the base.

[0026] By adopting the above solution, the elastic drive assembly has stable lateral elastic support, thereby ensuring that the shock-absorbing block has a better shock-absorbing effect.

[0027] Due to the adoption of the above technical solution, this utility model has significant technical effects: using an automatic guided vehicle (AGV) as a carrier to transport the wire transport vehicle, it can achieve unmanned operation in the wire transport yard, which not only reduces the workload of workers, but also effectively improves work efficiency and reduces the impact of the harsh workshop environment on workers' health. The drive mechanism can drive the locking hook mechanism to achieve stable connection and rapid separation between the automatic guided vehicle and the wire transport vehicle, thereby ensuring the normal handling operation of the wire transport vehicle.

[0036] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, the present embodiment discloses a wire car handling device, comprising an automatic guided vehicle 1 , the front side of which is provided with two sets of horizontally arranged locking hook mechanisms 2 , a driving mechanism connected to the locking hook mechanisms 2 , and a plurality of forks 16 .

[0038] In this embodiment, Figure 3 As shown, when the AGV 1 moves to the front of the wire transport trolley 17, the cargo fork 16 is inserted into the bottom of the wire transport trolley 17 to support the wire transport trolley 17. At the same time, the driving mechanism drives the locking hook mechanism 2 to rotate forward, so that the locking hook mechanism 2 can hook the horizontal bar 19 fixed to the front side of the wire transport trolley 17, thereby completing the connection between the AGV 1 and the wire transport trolley 17, and then the AGV 1 can drag the wire transport trolley 17.

[0039] On the contrary, if Figure 4 and Figure 5 As shown, when the driving mechanism drives the locking hook mechanism 2 to rotate backward, the locking hook mechanism 2 can be separated from the horizontal bar 19 on the front side of the wire transporting vehicle 17, thereby completing the separation of the automatic guided vehicle 1 and the wire transporting vehicle 17.

[0040] like Figure 4 As shown, in order to improve the firmness and balance of the connection between the locking hook mechanism 2 and the wire transport vehicle 17, a horizontal bar 19 is set on the front side of the base 13 of the wire transport vehicle 17 to lower the height of the dragging point of the wire transport vehicle 17, thereby improving the balance of the automatic guided vehicle 1 when transporting the wire transport vehicle 17.

[0041] Specifically, such as Figure 3 As shown, the cross section of the horizontal bar 19 is square, and the locking hook mechanism 2 includes a driving block 4 connected to the driving mechanism, a first positioning portion 5 and a second positioning portion 6 arranged on the driving block 4. When the driving mechanism drives the locking hook mechanism 2 to hook the horizontal bar 19 on the front side of the wire transport vehicle 17, the driving block 4 can drive the first positioning portion 5 to buckle to the side of the horizontal bar 19 away from the automatic guided vehicle 1, and at the same time drive the second positioning portion 6 to press the upper surface of the horizontal bar 19, thereby improving the stability of the locking hook mechanism 2 when docking with the horizontal bar 19.

[0042] like Figure 3 As shown, to improve the process efficiency of the hook mechanism 2 docking with the crossbar 19 and reduce wear during docking, a first pressure roller 7 is mounted on one side of the first positioning portion 5. The outer circumference of the first pressure roller 7 is used to abut the side of the crossbar 19 away from the automated guided vehicle 1. A second pressure roller 8 is mounted on one side of the second positioning portion 6. The outer circumference of the second pressure roller 8 is used to abut the upper surface of the crossbar 19. The second pressure roller 8 is preferably made of polyurethane, which has excellent elasticity and pressure resistance.

[0043] Correspondingly, such as Figure 5 and Figure 6 As shown, the drive mechanism includes a drive shaft 9 fixedly connected to the drive block 4 and rotatably mounted on the front side of the AGV 1, and a drive unit 10 connected to the drive shaft 9 to drive the drive shaft 9. Both ends of the drive shaft 9 are mounted on the front side of the AGV 1 via seated bearings 18. The drive unit 10 is a worm gear reduction motor mounted on the AGV 1, with its output shaft coaxially fixed to the drive shaft 9.

[0044] like Figure 7As shown, in order to improve the docking accuracy and efficiency of the automatic guided vehicle 1 and the wire transport vehicle 17, the front side of the automatic guided vehicle 1 is provided with at least one set of shock-absorbing mechanisms 11 for abutting against the horizontal bar 19 on the front side of the wire transport vehicle 17 to cushion the horizontal bar 19. Specifically, the shock-absorbing mechanism 11 includes a shock-absorbing block 12 provided on the front side of the automatic guided vehicle 1 and used to abut against the side of the horizontal bar 19. An elastic drive component is provided between the shock-absorbing block 12 and the front side of the automatic guided vehicle 1 for causing the shock-absorbing block 12 to have a tendency to move away from the automatic guided vehicle 1. The elastic drive component includes a base 13 fixed to the front side of the automatic guided vehicle 1, and a mounting seat 14 fixed to the side of the shock-absorbing block 12 close to the automatic guided vehicle 1. At least one guide spring 15 is provided between the base 13 and the mounting seat 14 to cause the mounting seat 14 to have a tendency to move laterally away from the base 13.

[0045] The specific working process is as follows:

[0046] When transporting a wire cart 17, the AGV 1 first moves to the front of the target cart 17, then inserts the fork 16 into the bottom of the cart 17 to support it. Next, the drive unit 10 rotates the drive block 4 forward via the drive shaft 9, allowing the first positioning portion 5 on the drive block 4 to engage with the side of the crossbar 19 facing away from the AGV 1 via the first pressure roller 7. Simultaneously, the second positioning portion 6 on the drive block 4 presses against the upper surface of the crossbar 19 via the second pressure roller 8, completing the connection between the AGV 1 and the wire cart 17.

[0047] At this point, the AGV 1 can use the running wheels 20 at the bottom of the wire transport vehicle 17 to transport the wire transport vehicle 17 to the designated location. Then, the driving unit 10 drives the driving fastener upward through the driving shaft 9, so that the first positioning portion 5 and the second positioning portion 6 are separated from the horizontal bar 19, thereby completing the separation of the AGV 1 and the wire transport vehicle 17, thereby facilitating the AGV 1 to perform the next transport task.
