Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a collaborative operation mechanism for conveyors inside and outside a freight elevator car includes a car 1. A fixed seat 3 is installed at the front of the car 1. Multiple vertically distributed freight partitions 2 are installed inside the car 1. Two symmetrically distributed support bars 9 are fixed on the upper surface of the freight partitions 2. Four symmetrically distributed adjusting hydraulic rods 10 are fixed on the bottom of the freight partitions 2. Four rotatable guide screws 4 are installed on the upper surface of the fixed seat 3. Lifting seats 7 are installed on the outer side of the four guide screws 4. The lifting seats 7 and the guide screws 4 are connected by a threaded transmission. A conveyor belt 8 is slidably installed on the upper surface of the lifting seats 7. The height of the lifting seats 7 and the conveyor belt 8 is adjusted by the guide screws 4 to transport the conveyor belt 8 carrying goods to a designated height. The goods are then delivered to the support bars 9 by the conveyor belt 8 and transferred to the support bars 9, realizing the automatic transfer of goods.

[0021] A delivery hydraulic rod 11 is fixed to the bottom of the lifting seat 7. An adjusting slider 12 is fixed to the movable end of the delivery hydraulic rod 11. The adjusting slider 12 passes through the lifting seat 7 and is fixed to the bottom of the conveyor belt 8. The adjusting slider 12 slides in contact with the lifting seat 7. The position of the conveyor belt 8 is adjusted by the delivery hydraulic rod 11 and the adjusting slider 12, so that the conveyor belt 8 can enter the car 1 or move out, thereby realizing the delivery of goods into the car 1 or the removal of goods from the car 1.

[0022] Four symmetrically distributed fixing rods 6 are also fixed on the upper surface of the fixed base 3. The top of the four fixing rods 6 is fixed with a limiting top plate 5. The top of the guide screw 4 is inserted into the bottom of the limiting top plate 5. The guide screw 4 and the limiting top plate 5 are rotatably connected by roller bearings. The limiting top plate 5 limits the upward movement height of the lifting base 7 and the conveyor belt 8, thereby preventing the lifting base 7 from falling off the guide screw 4 due to excessive upward movement.

[0023] The fixed base 3 includes a protective shell 31. The bottom end of the guide screw 4 extends through the top of the protective shell 31 and into the interior of the protective shell 31. The guide screw 4 and the protective shell 31 are rotatably connected by roller bearings. An adjusting motor 32 is fixed inside the protective shell 31. A drive gear 33 is fixed on the outer side of the output shaft end of the adjusting motor 32. Four symmetrically distributed transmission gears 34 are meshed around the drive gear 33. A transmission sprocket 35 is provided above the transmission gears 34. An output sprocket 37 is fixed on the outer side of the bottom end of the guide screw 4. A chain 36 is sleeved on the outer side of the transmission sprocket 35 and the output sprocket 37. The adjusting motor 32 and the drive gear 33 drive the four transmission gears 34 and the transmission sprocket 35 to rotate, thereby causing the transmission sprocket 35 to drive the guide screw 4 to rotate through the chain 36 and the output sprocket 37. This causes the four guide screws 4 to rotate synchronously, realizing the smooth lifting and lowering of the lifting base 7.

[0024] A rotating shaft is axially inserted into the transmission gear 34. The rotating shaft passes through the transmission sprocket 35 and its two ends are rotatably connected to the protective shell 31 through bearings.

[0025] Working principle: When using the car 1 to move goods, the goods are first transferred to the surface of the conveyor belt 8 by a forklift. Then, the power supply to the device is turned on and started. After the power is turned on, the height of the loading partition 2 is adjusted by adjusting the hydraulic rod 10 so that the height between adjacent loading partitions 2 can accommodate the goods. At the same time, the motor 32 is started and drives the drive gear 33, transmission gear 34, and transmission sprocket 35 to rotate. This causes the transmission sprocket 35, chain 36, and output sprocket 37 to drive the guide screw 4 to rotate. At this time, the guide screw 4 drives the lifting seat 7, the conveyor belt 8, and the goods to rise and fall, moving the goods to the corresponding loading partition 2. At this point, the delivery hydraulic rod 11 is activated, pushing the adjusting slider 12 and the conveyor belt 8 to slide, moving the end of the conveyor belt 8 above the cargo partition 2 and ensuring the bottom of the goods contacts the upper surface of the support bar 9. The conveyor belt 8 then starts to transfer the goods above the support bar 9. Subsequently, the adjusting motor 32 starts in reverse, driving the lifting seat 7 to descend, causing the conveyor belt 8 to separate from the goods. At this time, the delivery hydraulic rod 11 drives the adjusting slider 12 and the conveyor belt 8 to reset, realizing the transfer of goods. When removing goods from the cargo partition 2, only the reverse operation is required, realizing automatic transfer of goods, saving labor costs, and improving the efficiency of goods transportation and transfer.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
