Abstract
Description
Technical Field

DETAILED DESCRIPTION
[0027] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is used as a reference.
[0028] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0029] See attached Figure 1-3 The utility model provides a safety interlocking device for safety interlocking of a stacker and a shelf as a part of a three-dimensional warehouse. The three-dimensional warehouse is composed of a shelf, a conveyor line, an empty pallet stacking machine and a stacker. The safety interlocking device is fixedly arranged on the tension beam of the shelf. A plurality of pallets 8 for storing goods are arranged on the shelf. The tension beam (not shown) is located below the pallet 8. By arranging the safety interlocking device on the tension beam, the pallet 8 can be fixed when storing goods; when the stacker's push-pull rod takes out the pallet 8, the push-pull rod of the stacker pushes the thrust swing rod 5 of the safety interlocking device to open the safety interlocking device and take out the pallet 8.
[0030] The safety interlocking device includes a supporting base 6 , a locking mechanism 1 for locking the tray 8 , a thrust rocker 5 for opening the locking mechanism 1 , and a resetting mechanism for resetting the locking mechanism 1 .
[0031] The support base 6 is fixed on the tension beam, and the thrust swing rod 5 is arranged at the front end of the support base 6 and is rotatably connected to the support base 6 through a rotating shaft. The rear end of the support base 6 is provided with a connecting portion 61 protruding from the upper surface of the support base 6, and the locking mechanism 1 is rotatably connected to the connecting portion 61 through a rotating shaft.
[0032] A limit screw 2 is provided on the side of the support base 6, and the limit screw 2 is used to limit the rotation of the locking mechanism 1. A lock hook 11 is provided at the front end of the locking mechanism 1, and a limit portion 12 is vertically provided at the rear end of the locking mechanism 1. In the locked state, the lock hook 11 abuts against the tray 8, and the limit portion 12 abuts against the limit screw 2.
[0033] The middle part of the thrust swing rod 5 is bent, and the two ends of the thrust swing rod 5 face upward, and the bent part is rotatably connected to the support base 6 through a rotating shaft. The end of the thrust swing rod 5 connected to the lock hook 11 is provided with a first through slot 13, and the front end of the lock hook 11 is inserted into the first through slot 13. The front end of the lock hook 11 is provided with a second through slot 14 for connecting the thrust swing rod 5. The connecting shaft 9 passes through the thrust swing rod 5 and the second through slot 14, so that the thrust swing rod 5 and the lock hook 11 are rotatably connected.
[0034] A force bearing 7 is provided at the front end of the thrust swing rod 5. The push-pull rod of the stacker pushes one end of the thrust swing rod 5 with the force bearing 7 to rotate the thrust swing rod 5, and the other end connected to the locking hook 11 presses the locking hook 11 downward, so that the push-pull rod can extend under the pallet 8 to pull the pallet 8 out.
[0035] The reset mechanism includes a connecting rod 10 and a tension spring 3 arranged on the side of the support base 6. One end of the connecting rod 10 is fixedly connected to the support base 6, and the other end of the connecting rod 10 is connected to the tension spring 3. The tension spring 3 is connected to the limit portion 12. By setting the tension spring 3, the limit portion 12 of the locking mechanism 1 is abutted against the limit screw 2 to achieve locking of the tray 8. After the force bearing 7 loses the pressure of the push-pull rod, the locking mechanism 1 is reset under the action of the tension spring 3.
[0036] The side of the lock hook 11 is also provided with a detection reflector 4 for sensing the push-pull rod. The detection reflector 4 is an induction switch interlocked with the stacker to prevent the pallet 8 from being pulled when the lock hook 11 is not opened, causing damage to the cargo platform dragging device.
[0037] The safety interlocking device of the utility model is fixed on the tension beam of the shelf. When the pallet 8 is in the storage state, under the tension of the tension spring 3, the lock hook 11 of the locking mechanism 1 can buckle the pallet 8 to keep the pallet 8 on the shelf.
[0038] When the pallet 8 is to be taken out from the push-pull rod of the stacker, the push-pull rod extends to the bottom of the pallet 8, pushes the load bearing 7, drives the thrust swing rod 5 to press the lock hook 11 downward, so that the push-pull rod can continue to extend to the bottom of the pallet 8, and then the pallet 8 is pulled out through the rollers on the stacker and the shelf.
[0039] When the push-pull rod of the stacker puts the pallet 8 into the shelf, the push-pull rod carries the pallet 8 to the position of the thrust swing rod 5, pushes the force bearing 7 to drive the thrust swing rod 5 to press the lock hook 11 downward, so that the pallet 8 can be sent into the shelf. After the pallet 8 is in place, the lock hook 11 automatically resets and locks the pallet 8 under the tension of the tension spring 3.
[0040] The utility model provides a safety interlocking device, which is arranged on the tension beam of the shelf, and meets the interlocking requirements between the stacker and the pallet 8. When the push-pull rod of the stacker does not open the safety interlocking device, the pallet 8 can be locked on the shelf to prevent the pallet 8 from slipping off the shelf. After the push-pull rod opens the safety interlocking device and puts the pallet 8 in, the lock hook 11 can automatically reset and lock the pallet 8, and prevent the pallet 8 from sliding out of the shelf and colliding when the push-pull rod is not fully reset.
