[0050] When in use, the side frame 4 or the bolster 5 can be directly placed on the relatively arranged flexible clamping mechanism 2 and transported by the chain conveyor 1.
[0051] As a preferred implementation in this embodiment, the flexible clamping mechanism 2 includes a plurality of relatively arranged bayonet bases 2002, the bayonet bases 2002 being mounted on the connecting chain plates 2001 of the chain conveyor 1, the bayonet bases 2002 being provided with bolster clamping blocks 2007 and side frame L-shaped clamping blocks 2006 in sequence from top to bottom, the bolster clamping blocks 2007 being rotatably connected to the bayonet base 2002 via a first rotating shaft 2008, and the side frame L-shaped clamping blocks 2006 being rotatably connected to the bayonet base 2002 via a second rotating shaft 2010;
[0052] The bayonet base 2002 is provided with a first limit stop 2005 and a second limit stop 2009 in the upper and lower parts;
[0053] Upper support wheels 2003 are rotatably mounted on the bayonet base 2002;
[0054] A return spring 2017 is built into the bayonet base 2002, and the two ends of the return spring 2017 are respectively connected to the bayonet base 2002 and the side end of the rocker clamping block 2007;
[0055] The lower support wheel 2004 is rotatably mounted on the connecting chain plate 2001, and the lower end of the lower support wheel 2004 is in rolling contact with the chain plate support block 2012 at the upper end of the chain plate conveyor 1;
[0056] A protective mechanism is also provided to prevent the return spring 2017 from being damaged due to prolonged transition extrusion.
[0057] The hoisted side frame 4 or bolster 5 can be directly placed on the buffer conveyor device, and the side frame 4 or bolster 5 can be buffered and transported by the buffer conveyor device;
[0058] When placing the side frame 4 (as Figure 5 As shown), the two ends of the side frame 4 are supported on the bottom edges of two sets of oppositely arranged side frame L-shaped clamping blocks 2006, and the upper ends of the oppositely arranged side frame L-shaped clamping blocks 2006 clamp the two ends of the side frame 4;

[0060] The lower supporting wheels 2004 are arranged and are in rolling contact with the chain plate supporting blocks 2012 to offset the downward pressure of the side frame 4 or the bolster 5 and prevent the transmission components in the chain plate conveyor 1 from being damaged due to excessive pressure.
[0061] It should be noted that: 1. When the hoist removes the bolster 5 placed on the buffer conveying device, the bolster clamping block 2007 is automatically restored to the original position through the elastic force of the return spring 2011; 2. The first limiting stop 2005 is welded at the limit position to prevent the bolster clamping block 2007 from rotating too much and affecting the clamping of the lower wheels; 3. The center of gravity of the side frame L-shaped clamping block 2006 is always located outside the second shaft 2010 (i.e. close to the side of the upper supporting wheel 2003), so at the beginning, the outer side of the side frame L-shaped clamping block 2006 is in contact with the second limiting stop 2009, even if the side frame L-shaped clamping block 2006 is arranged to bear the side frame 4 or the bolster 5, the center of gravity of the side frame L-shaped clamping block 2006 is always located outside the second shaft 2010, and when the side frame 4 or the bolster 5 is removed, the side frame L-shaped clamping block 2006 rotates outward around the second shaft 2010 by its own gravity and finally contacts the second limiting stop 2009; 4. The chain plate conveyor 1 and the track gauge adjusting mechanism 3 are electrically connected with the PLC controller.

[0064] When the rocker clamp block 2007 is subjected to extrusion from the workpiece, it will rotate, and in the process of rotation, the return spring 2017 will be compressed, and at the same time, the unlocking rod 2016 will move to the left relative to the two groups of positioning rods 2019 (at this time, the positioning rod 2019 will be moved outward from the positioning groove cavity provided in the clamping base 2002 by the elastic force of the fixing spring 2020), when the return spring 2017 is compressed to the limit, the positioning rod 2019 moves out of the positioning groove, at this time, the positioning of the fixing cylinder 2014 is released, the rocker clamp block 2007 is released from the first limiting stop 2005, and the damage of the return spring 2017 caused by long-time extrusion can be effectively avoided.
[0065] As a preferred embodiment in the present embodiment, as shown in Figure 4 The positioning rod 2019 is provided in a cylindrical structure, and the end of the positioning rod 2019 is provided in a conical structure.
[0066] The positioning rod is in a cylindrical structure, so that the fixing cylinder 2014 can rotate by itself according to the need after being extruded, to adapt to the change of the direction of the force.

[0068] The friction between the positioning rod 2019 and the unlocking rod 2016 can be reduced.
[0069] As a preferred embodiment in the present embodiment, as shown in Figure 4 The positioning rod 2019 penetrates the right end of the fixing cylinder 2014 and is fixed with a pull rod, and the pull rod is perpendicular to the positioning rod 2019.
[0070] When the positioning rod 2019 is inserted and installed with the positioning groove, the pull rod can be used to compress the return spring 2017, so that the positioning rod 2019 is inserted with the positioning groove.
[0071] As a preferred embodiment in the present embodiment, as shown in Figure 2As shown, the upper end of the chain plate support block 2012 is provided with a guide rib 2013, and the bottom of the connecting chain plate 2001 is provided with a limiting groove matched with the guide rib 2013.
[0072] Through the cooperation of the guide rib 2013 and the limiting groove, the movement of the connecting chain plate 2001 can be effectively prevented, which is beneficial to the stability of clamping the workpiece.
[0073] As a preferred embodiment in the present embodiment, as shown in Figure 5 As shown, the track gauge adjusting mechanism 3 comprises an electric telescopic cylinder 3001, and the output end of the electric telescopic cylinder 3001 is connected with a moving base 3002, wherein a group of chain plate conveyors 1 are installed on the moving base 3002, and the moving base 3002 is slidingly arranged on the base 1001.
[0074] The moving base 3002 can be moved by controlling the electric telescopic cylinder 3001 to work, and then the distance between the two chain plate conveyors 1 is changed to adapt to different specifications of the side frame 4 and the bolster 5.
[0075] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
