Meanwhile, in order to realize that the cargo carrying platform can be uniformly locked under the stress so that the RGV track on the cargo carrying platform is in butt joint with the RGV track on the ground or a goods shelf, the butt joint locking devices are arranged at the two sides of the bottom surface of the cargo carrying platform. The following detailed description is provided:

the locking part is including locking seat 2, go up the knock pin axle 3 and offset down the axle 4, go up knock pin axle 3 and offset down and set up on locking seat 2 and both mutual parallel arrangement along its axial displacement, in order to make go up knock pin axle 3 and offset down and the axle 4 and can steadily remove and further restrict the direction of movement of both, the integrated into one piece has an I-shaped support 5 on locking seat 2 and it goes up and offset down and be equipped with a round pin axle guide channel 6 along the axial of knock pin axle 3 and offset down 4, and then will go up knock pin axle 3 and offset down and the axle 4 removal sets up in round pin axle guide channel 6 and its both ends run through I-shaped support 5 respectively and set up. For convenience of description, the end of the upper knock-out shaft 3 and the lower knock-out shaft 4 close to the abutting part is defined as a locking end, and the end distant from the abutting part is defined as a driving end.

The upper jacking pin shaft 3 and the lower jacking pin shaft 4 are linked in the same locking part through a swinging rod 7, namely the center position of the swinging rod 7 is rotationally connected with the locking seat 2, and two ends of the swinging rod 7 are respectively connected with the shaft bodies of the upper jacking pin shaft 3 and the lower jacking pin shaft 4 close to the driving end in a sliding manner. In this embodiment, a rotating shaft 8 is vertically disposed at the center of the side of the swing rod 7 facing the locking seat 2, the rotating shaft 8 is rotatably connected with the locking seat 2 through a bearing 9, two ends of the swing rod 7 are respectively provided with a bar-shaped sliding through hole 10, the upper knock pin shaft 3 and the lower knock pin shaft 4 are close to the driving end and face the shaft body of the swing rod 7, a connecting surface 11 is formed by milling, and a sliding connecting block 12 is convexly disposed on the connecting surface 11, and the sliding connecting blocks 12 on the upper knock pin shaft 3 and the lower knock pin shaft 4 are respectively correspondingly and slidably disposed in the bar-shaped sliding through holes 10 on the swing rod 7 so as to be respectively slidably connected with the swing rod 7. It will be understood that when the locking end of the upper pin shaft 3 moves toward the docking member, the sliding connection block 12 on the upper pin shaft 3 slides in the bar-shaped sliding through hole 10 on the swing rod 7 and drives the swing rod 7 to rotate with the rotation shaft 8 as the rotation center, and in this process, the sliding connection block 12 in the other bar-shaped sliding through hole 10 provided on the swing rod 7 slides in the corresponding bar-shaped sliding through hole 10 to drive the lower offset shaft 4 to move away from the docking member, and vice versa.

In order to further reduce the number of driving parts, a linkage rod 13 is added to synchronize the two locking parts, that is, one end of the rotating shaft 8, which is rotatably connected with the locking seat 2, is arranged through the locking seat 2 and fixedly provided with an L-shaped connecting column 14 thereon, and two ends of the linkage rod 13 are rotatably connected with the L-shaped connecting columns 14 in the two locking units through joint bearings 24 respectively. When the upper top pin shaft 3 or the lower offset shaft 4 in one locking part moves along the axial direction, the swing rod 7 connected with the upper top pin shaft 3 or the lower offset shaft drives the rotating shaft 8 to rotate, and the end part of the linkage rod 13 is in rotary connection with the L-shaped connecting column 14 on the rotating shaft 8, so that the linkage rod 13 moves along with the L-shaped connecting column 14 in the other locking part in the process of rotating along with the rotating shaft 8, the L-shaped connecting column 14 in the other locking part in rotary connection with the linkage rod 13 is driven to rotate along with the L-shaped connecting column 14, and the swing rod 7 in the locking part also swings along with the L-shaped connecting column 14 through the rotating shaft 8 fixedly connected with the L-shaped connecting column, so that the lower top pin shaft 4 or the upper top pin shaft 3 in the locking part moves along the axial direction. Only one of the locking parts, namely the upper and lower counter-pin shafts 3, 4, is operatively connected to a driving part, which may be an electric cylinder, an air cylinder, a hydraulic cylinder or a direct die set, without special requirements.

In this embodiment, the driving means is a cylinder 15 and is operatively connected to the driving end of a lower abutment pin 4 in a locking means. When the electric cylinder 15 drives the lower offset shaft 4 to move away from the butting component along the axial direction of the lower offset shaft, the upper offset shaft 3 in the locking component stretches out towards the butting component along the axial direction of the upper offset shaft under the transmission of the swinging rod 7, and meanwhile, the upper offset shaft 3 in the other locking component stretches out towards the butting component along the axial direction of the upper offset shaft through the transmission of the linkage rod 13, so that the upper offset shafts 3 in the two locking components stretch out simultaneously. On the contrary, when the electric cylinder 15 drives the lower offset shaft 4 to extend towards the direction of the butting component along the axial direction, the upper offset shaft 3 in the locking component moves and withdraws towards the direction away from the butting component along the axial direction under the transmission of the swinging rod 7, meanwhile, the upper offset shaft 3 in the other locking component moves and withdraws towards the direction away from the butting component along the axial direction through the transmission of the linkage rod 13, and the lower offset shaft 4 in the locking component is driven to extend towards the direction of the butting component along the axial direction through the transmission of the swinging rod 7, so that the lower offset shafts 4 in the two locking components extend simultaneously.

In the process of extending and retracting the upper top pin shaft 3 or the lower top pin shaft 4 of the two locking parts, in order to prevent the upper top pin shaft 3 and the lower top pin shaft 4 from rotating circumferentially in the moving process, a limiting supporting block 16 is respectively arranged on the side surface of the I-shaped support 5, which is close to the driving end of the upper top pin shaft 3 and the lower top pin shaft 4, corresponding to the positions of the upper top pin shaft 3 and the lower top pin shaft 4, and a limiting supporting surface 17 is respectively formed on the circumferential outer side surfaces of the upper top pin shaft 3 and the lower top pin shaft 4 along the axial direction of the positions facing the limiting supporting block 16. Whether or not the upper knock pin 3 and the lower knock pin 4 are in a moving state, the stopper abutment block 16 is disposed opposite to the stopper abutment surfaces 17 of the upper knock pin 3 and the lower knock pin 4, thereby restricting circumferential rotation of the upper knock pin 3 and the lower knock pin 4 at all times.

In addition, the locking seat 2 is provided with a proximity sensor 18 extending towards the upper top pin 3 and the lower top pin 4 respectively corresponding to the original positions of the driving ends of the upper top pin 3 and the lower top pin 4, the tops of the circumferential sides of the driving ends of the upper top pin 3 and the lower top pin 4 are provided with a sensing piece 19 vertically respectively corresponding to the tops of the circumferential sides of the driving ends of the upper top pin 3 and the lower top pin 4, and the proximity sensor 18 is connected with the sensing piece 19 in a sensing way when the upper top pin 3 and the lower top pin 4 are in an initial state, i.e. do not extend towards the butting part. The sensing of the proximity sensor 18 and the sensing piece 19 detects whether the upper knock pin shaft 3 and the lower knock pin shaft 4 in the two locking parts are in the initial state.

The butt joint part corresponding to each locking part comprises a butt joint fixing seat 20, an upper top bolt 21 and a lower supporting bolt 22, wherein the cross sections of the butt joint fixing seats 20 are U-shaped, the side edges of the butt joint fixing seats 20 are fixed on the main frame 1 of the stacker, openings of the two butt joint fixing seats 20 in the two butt joint parts are oppositely arranged, and the upper end and the lower end of each butt joint fixing seat 20 are respectively and vertically connected with the upper top bolt 21 and the lower supporting bolt 22 in a threaded manner. By arranging the top parts of the upper top bolt 21 and the lower abutment bolt 22 in the opening of the docking holder 20 so that the two top surfaces respectively form an upper top surface (not shown in the figure) and a lower abutment surface (not shown in the figure), the distance between the upper top surface and the lower abutment surface can be adjusted by rotating the upper top bolt 21 and the lower abutment bolt 22 according to the actual situation. Corresponding to this is that the abutment positioning surfaces 23 are formed on the locking end circumferential side surfaces of the upper knock pin shaft 3 and the lower knock pin shaft 4 in the two locking members corresponding to the upper top surface of the upper knock bolt 21 and the lower abutment surface of the lower knock bolt 22, respectively, and the abutment positioning surfaces 23 of the upper knock pin shaft 3 or the abutment positioning surfaces 23 of the lower knock pin shaft 4 in the two locking members are simultaneously brought into abutting contact with the upper top surface of the upper knock bolt 21 or the lower abutment surface of the lower knock bolt 22 in the corresponding abutting member to restrict the downward movement or upward movement of the cargo bed.

The specific working process is as follows:

the proximity sensor 18 is inductively coupled to the inductive element 19 to confirm that both the upper and lower knock pins 3, 4 in the two locking members are in the initial state. When a heavy-load RGV needs to walk from a stacker cargo bed to the ground or a goods shelf, the electric cylinder 15 is started and drives the lower offset shaft 3 connected with the electric cylinder to move along the axial direction of the electric cylinder far away from the butt joint fixing seat 20, and at the moment, the upper offset shaft 3 in the locking part stretches out along the axial direction of the electric cylinder towards the butt joint fixing seat 20 under the transmission of the swinging rod 7 and enables the abutting locating surface 23 on the upper offset shaft to be in abutting contact with the upper top surface of the upper offset bolt 21 on the corresponding butt joint fixing seat 20. At the same time, the upper top pin 3 in the other locking part also extends towards the butt fixing seat 20 along the axial direction under the transmission of the linkage rod 13, and makes the abutting surface 23 on the upper top pin contact with the upper top surface of the upper top bolt 21 on the corresponding butt fixing seat 20. The upper top pin shafts 3 in the two locking parts are in abutting contact with the upper top surfaces of the upper top bolts 21 on the corresponding butt joint fixing seats 20 to provide upward movement restriction for the cargo carrying platform, so that the situation that the cargo carrying platform slides upwards for a certain distance due to the fact that the steel wire ropes are stressed and stretched due to the dead weight of the heavy-duty RGV is avoided.

When a heavy-load RGV needs to be loaded and operated on a stacker load table, the electric cylinder 15 is started and drives the lower offset shaft 4 connected with the electric cylinder to extend to the lower offset positioning surface 23 on the lower offset positioning surface along the axial direction of the lower offset positioning surface towards the butt fixing seat 20 to be in abutting contact with the lower abutting surface of the lower abutting bolt 22 on the corresponding butt fixing seat 20, and the upper offset shaft 3 in the locking part is retracted along the axial direction of the lower offset positioning surface towards the direction away from the butt fixing seat 20 under the transmission of the swing rod 7. The upper top pin 3 in the other locking part is moved and retracted in the axial direction of the upper top pin away from the butting part 20 under the transmission of the linkage rod 13, and the lower canceling shaft 4 in the locking part is enabled to extend to the upper abutting locating surface 23 in the axial direction of the lower canceling shaft towards the butting fixing seat 20 by the transmission of the swinging rod 7, so that the lower abutting locating surface of the lower canceling shaft is in abutting contact with the lower abutting surface of the lower abutting bolt 22 on the corresponding butting fixing seat 20. The lower supporting bolts 4 in the two locking parts are in abutting contact with the lower supporting surfaces of the lower supporting bolts 22 on the corresponding butt joint fixing seats 20 to provide downward movement restriction for the cargo carrying platform, so that the condition that the cargo carrying platform slides downwards by a certain distance due to rebound caused by stress alleviation of the steel wire rope is avoided.
