It involves assembling and installing the various components of a vehicle, gradually completing the final assembly of the vehicle. Within the final assembly line, various conveying and transfer equipment are required to facilitate the movement and transfer of components and vehicles.

[0003] Before cars roll off the assembly line, the plate chain conveyor line and the conveyor line for the preceding process require corresponding transfer equipment designed based on the initial process layout. Existing transfer equipment is typically designed with fixed shapes and sizes, suitable for vehicles of specific types or sizes, and cannot adapt to different wheelbases and, therefore, different vehicle models. In addition, before the final plate chain line transfer, the vehicle part is transported by a sling as a carrier. The support pin holes of the vehicle part serve as the carrier support. The transfer equipment needs to support the vehicle part's tires to achieve the transfer. Existing transfer equipment often uses a support fork to support the vehicle part's tires, but the mechanical structure used by existing transfer equipment to solve the problem of opening and retracting the support fork is complex.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0035] Example 1

[0036] See also Figure 1-3 , This embodiment provides a support fork extension and retraction mechanism, comprising: a frame body; a linear slide track 1 arranged in the frame body; and two drag fork extension and retraction assemblies symmetrically arranged on both sides of the linear slide track 1 along the length direction of the linear slide track 1, each of the drag fork extension and retraction assemblies comprising a driving element 2 arranged on the outer side of the end of the linear slide track 1, preferably a driving cylinder; an end plate 3 connected to the output end of the driving element 2, the end plate 3 is provided with a clamping plate 4, the end plate 3 is slidably connected to the linear slide track 1; and two support forks 5 symmetrically arranged on both sides of the linear slide track 1 along the width direction of the linear slide track 1, the support fork 5 includes a first connecting plate 51 and a second connecting plate 52 rotatably connected, the first connecting plate 51 is provided with two clamping wheels 6 on the side facing away from the second connecting plate 52, the two clamping wheels 6 are cooperated and connected with the protrusions 41 arranged at the end of the clamping plate 4, as the clamping plate 4 extends and retracts under the action of the driving element 2, the first connecting plate 51 is driven to rotate counterclockwise or clockwise, thereby realizing the retraction or extension of the second connecting plate 52.

[0037] There are four supporting forks 5 which are respectively arranged at the four corners of the frame body, and the first connecting plate 51 and the second connecting plate 52 are rotatably connected by a rotating shaft 7 which passes through the frame body.

[0038] Specifically, this embodiment drives the card plate 4 linearly through the driving element 2. The card plate 4 has a groove 42, and the support fork 5 is equipped with two yoke-type card wheels 6. When the card plate 4 moves forward, the roller on the support fork 5 falls into the groove 42. As the card plate 4 moves, the support fork realizes the retraction and opening action, and the linear action is switched to the rotation action. When the support fork 5 is in the open state, the card wheel 6 on the support fork 5 forms a card point position with the card plate 4, thereby limiting the rotation of the support fork 5.

[0039] Example 2

[0040] See also Figure 4-7 This embodiment also provides a traveling transfer device, including: an elevator, including a lifting platform 8; a first fork extending and retracting mechanism 10 and a second fork extending and retracting mechanism 11 arranged on the lifting platform 8, the first fork extending and retracting mechanism 10 and the second fork extending and retracting mechanism 11 are both the fork extending and retracting mechanisms as described in Example 1; a trolley track 15 arranged on the lifting platform 8, a trolley for supporting the first fork extending and retracting mechanism 10 and the second fork extending and retracting mechanism 11 is provided in the trolley track 15; a trolley driving module 14 connected to the trolley for driving the trolley.

[0041] In this embodiment, a synchronous belt 16 is further provided on the trolley, and the first fork extending and retracting mechanism 10 is installed on the synchronous belt 16. As the synchronous belt 16 rotates, the distance between the first fork extending and retracting mechanism 10 and the second fork extending and retracting mechanism 11 changes.

[0042] In this embodiment, an encoder module is further provided on the lifting platform 8 , and the encoder module is used to provide feedback on the positional relationship between the first support fork extending and retracting mechanism 10 and the second support fork extending and retracting mechanism 11 .

After the spreader vehicle enters the station, it stops at a fixed position. The proximity switch d mounted on the track f is sensed by the inductive switch bracket on the spreader trolley assembly c, which stops the vehicle, and the vehicle part b suspended on the spreader e stops.

[0048] like Figure 9 As shown, after the vehicle part b suspended on the sling e stops, the lifting platform 8 is lifted up, and the supporting fork supports the tire of the vehicle part, so that the vehicle part is separated from the sling positioning support pin, and the vehicle part b is separated from the sling e.

[0049] like Figure 10 As shown, after the vehicle part b is separated from the sling e, the opening mechanism opens the sling e, and the sling e continues to move forward.

[0051] like Figure 12 As shown, the lifting platform 8 descends, and the vehicle part b is placed on the plate chain conveying surface 9, and the supporting fork is retracted.

[0052] like Figure 13 As shown, after the fork is retracted, the trolley returns to the starting position and is ready to receive the next part.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
