AI Technical Summary
When using existing freight forwarding vehicles, operators cannot be sure whether the forks are fully engaged with the pallet, posing a safety hazard.
The device employs a combination structure of a rotating plate, a proximity sensor, and an elastic element. The proximity sensor is triggered by the pallet pushing the rotating plate to detect the insertion status of the fork arm, and the controller prompts the operator that the fork arm has been fully inserted into the pallet.
It effectively avoids situations where the fork arm and pallet are not properly engaged, preventing pallets and goods from falling and eliminating safety hazards.

[0002] The goods carrier is a carrier device for carrying goods, and when the two fork arms of the goods carrier are fully inserted into the pallet at the bottom of the goods, the pallet and the goods can be lifted, and then when the goods carrier moves, the goods can be carried. However, when the two fork arms are inserted into the pallet at the bottom of the goods, the operator cannot know whether the two fork arms are fully inserted into the pallet, and if the two fork arms are not fully inserted into the pallet, the pallet and the goods may fall off the two fork arms during subsequent carrying of the goods, which poses a safety hazard. SUMMARY
[0003] The utility model solves the technical problem of providing a carrier goods in place detection structure, which can avoid the situation that the two fork arms are not fully inserted into the pallet.
[0004] The utility model provides a carrier goods in place detection structure, which comprises a lifting frame and two fork arms symmetrically connected to the bottom of the lifting frame. The carrier goods in place detection structure further comprises a rotating plate, a proximity sensor and a resilient member. The middle part of the lower end of the lifting frame is provided with an open slot, and the rotating plate is arranged at the open slot. The upper end of the rotating plate is rotatably connected to the lifting frame above the open slot. The proximity sensor is installed on the lifting frame at the rear side of the open slot, and the proximity sensor is electrically connected to the controller in the carrier. The resilient member is arranged between the rear side of the lower end of the rotating plate and the lifting frame, and is used to apply a force to the lower end of the rotating plate to rotate the lower end of the rotating plate back to the front side. When the two fork arms are inserted into the pallet at the bottom of the goods and the pallet pushes the lower end of the rotating plate to rotate to the rear side, the rotating plate triggers the proximity sensor.
[0005] After the two fork arms in the carrier are fully inserted into the pallet at the bottom of the goods, the pallet can push the lower end of the rotating plate to rotate the lower end of the rotating plate to the rear side. At this time, the rotating plate can trigger the proximity sensor, so that the controller in the carrier can receive the trigger signal, and the controller can prompt the operator through the display panel that the fork arms have been fully inserted into the pallet at the bottom of the goods, thereby avoiding the situation that the two fork arms are not fully inserted into the pallet. When the carrier carries the goods, the situation that the pallet and the goods fall off the two fork arms can be effectively avoided, and the safety hazard is eliminated.

[0007] In a possible implementation, the trolley goods-in-place detection structure further comprises a first support; the first support is fixed to the rear side of the lower end of the lifting frame, and the proximity sensor is fixed to the lower end of the first support; when the tray pushes the lower end of the rotating plate to make the lower end of the rotating plate rotate towards the rear side, one of the flanges is used to trigger the proximity sensor; after the structure is used, after the two fork arms are completely inserted into the tray at the bottom of the goods, the tray can push the lower end of the rotating plate to make the lower end of the rotating plate rotate towards the rear side, at this time, the flange on the side of the proximity sensor can trigger the proximity sensor, so that the controller in the trolley can receive the trigger signal, and the controller can prompt the operator through the display panel that the fork arms have been completely inserted into the tray at the bottom of the goods.
[0008] In a possible implementation, the trolley goods-in-place detection structure further comprises a second support and a spring box; the upper end of the second support is fixed to the lower end of the lifting frame, the spring box is fixed to the lower end of the second support, the elastic member is a spring, the spring is arranged in the spring box, the rear end of the spring abuts against the inner side of the rear end of the spring box, and the front end of the spring abuts against the rear side of the lower end of the rotating plate; after the spring is used as the elastic member, the structure is simple and the cost is low, and in addition, during the process that the fork arms are separated from the tray at the bottom of the goods, when the tray releases the pushing state of the lower end of the rotating plate, the spring can drive the lower end of the rotating plate to rotate forward and reset.
