There are large gaps between the shelves, and the staff can continue to store goods at these positions to increase the storage capacity of the cold storage.

[0013] Furthermore, the lifting device comprises:

[0014] A second motor connected to the trigger switch;

[0015] gear;

[0016] The chain cooperates with the gear;

[0017] A chain collector, which cooperates with the chain and is connected to the second motor;

[0018] A pulley connected to the gear and the chain collector;

[0019] A transmission belt, which transmits power to the pulley;

[0020] A connecting frame connected to the chain;

[0021] Wherein, the trigger switch is connected to the connecting frame, and the fork is connected to the connecting frame.

[0022] In the present technical solution, a second motor connected to the trigger switch is arranged on the lifting device, the second motor is connected to the chain collector and the pulley, the pulley is also connected to the gears, and the gears and the chain collector are transmitted through the cooperation between the pulley and the transmission belt, so that the chain is lifted and lowered by the synchronous rotation of the gear and the chain collector, and a connecting frame is connected to the chain, and a trigger switch and a fork are installed on the connecting frame, so that when the transport vehicle approaches the shelf, the first trigger on the transport vehicle can activate the trigger switch on the connecting frame, and the trigger switch then drives the second motor to rotate, so that the fork is lifted and lowered through the connecting frame, thereby realizing the function of automatically loading and unloading goods in the cold storage.

[0023] Furthermore, the storage frame includes:

[0024] A first projection including a notch;

[0025] A second trigger, which cooperates with the trigger switch;

[0026] Wherein, the transport vehicle is provided with a second protrusion, the second protrusion cooperates with the notch, and the first protrusion cooperates with the fork.

[0027] In the present technical solution, a first protrusion with a groove is provided at the bottom of the cargo storage frame, and the width of the first protrusion is slightly smaller than the width between the forks, so that the first protrusion cooperates with the forks, so that the forks are aligned with the bottom of the cargo storage frame and the cargo storage frame can be stably lifted at the same time. A second protrusion is provided on the transport vehicle, and the second protrusion cooperates with the groove on the first protrusion. When loading, the cargo storage frame can be stably placed on the transport vehicle, and the forks can accurately lift the cargo from the transport vehicle, thereby enhancing the automatic loading function of the present device. A second trigger is also provided on the cargo storage frame. When unloading, the transport vehicle pushes the second trigger on the cargo storage frame, and the second trigger activates the trigger switch on the shelf to complete the subsequent unloading work, thereby enhancing the automatic unloading function of the present device.

[0028] Furthermore, the second protrusion is provided with a forward / reverse switch;

[0029] Wherein, the forward / reverse switch is connected to the first motor.

[0030] The fork then lowers the cargo box and the forward / reverse switch in the cargo box triggers the forward / reverse switch in the cargo box, which in turn triggers the first motor to reverse, causing the first motor to drive the transport cart with the cargo box away from the shelf after the fork lifts the cargo box on the transport cart, thereby facilitating the transport cart to reset after the loading is completed. At the same time, when the fork is lowered to place the cargo box, it avoids collision with the transport cart during this process. When unloading, the first motor rotates forward to drive the transport cart with the cargo box close to the shelf. After the fork lifts the cargo box, the transport cart continues to approach the shelf to the loading area. At this time, the fork lowers with the cargo box, and after the cargo box is placed on the transport cart, the forward / reverse switch is triggered, which in turn triggers the first motor to reverse, causing the first motor to drive the transport cart with the cargo box away from the shelf, thereby facilitating the transport cart to reset after the unloading is completed.

[0034] In the technical solution, an infrared sensor connected to the second motor is arranged on the shelf, a thermistor is installed on the bottom of the transport vehicle, and the thermistor is installed on the same side as the first trigger. When the second motor rotates forward, the infrared sensor causes the second motor to reverse through the thermistor. When loading, the transport vehicle approaches the shelf, and the infrared sensor passes through the thermistor for the first time. At this time, the second motor does not rotate forward and is not affected. After loading, the transport vehicle starts to move away from the shelf, and the infrared sensor passes through the thermistor for the second time, causing the second motor in the forward rotation state to reverse, that is, the fork is moved away from the shelf. The rise turns into a fall to place the cargo box, and at this time the transport cart will not collide with the cargo box in the descending process. When unloading, the transport cart approaches the shelf for the first time, causing the first motor to rotate forward, driving the fork and the cargo box to rise. At this time, the infrared sensor does not pass through the thermistor. When the fork and the cargo box rise to the loading position, the transport cart approaches the shelf for the second time. At this time, the infrared sensor passes through the thermistor to reverse the second motor in the forward state, that is, the fork turns from rising to falling, so as to place the cargo box on the transport cart. The above technical features are used to enhance the automatic loading and unloading function of this equipment.

[0035] Furthermore, the fork is provided with a limit block and an anti-slip pad.

[0036] In the present technical solution, by arranging limit blocks and anti-slip pads on the forks, the anti-slip pads are made of antifreeze rubber, and the limit blocks and anti-slip pads are arranged on the forks, so that the equipment is more stable during the loading and unloading process, and the limit blocks make the positioning of the forks on the cargo storage frame more accurate, thereby improving the accuracy and quality of automatic loading and unloading of the equipment.

[0037] The beneficial effects of this application are:

[0038] 1. When loading, the first trigger activates the trigger switch, so that the lifting device drives the fork to rise, the fork lifts the storage box, the transport vehicle retreats, the lifting device descends, the fork places the storage box on the ground, and the loading is completed. When unloading, the transport vehicle pushes the storage box to activate the trigger switch, so that the lifting device drives the fork to rise, the fork lifts the storage box, the transport vehicle moves forward, the lifting device descends, the fork places the storage box on the transport vehicle, and the unloading is completed, so that the equipment can automatically load and unload goods, reduce manual operations, and improve work efficiency.

[0039] 2. The second motor is connected to the chain collector and the pulley, and the pulley is also connected to the gears, so that the gears and the chain collector transmit to each other, so that the chain can be raised and lowered. A connecting frame is installed on the chain. When the transport vehicle approaches the shelf, the first trigger activates the trigger switch on the connecting frame, and the trigger switch drives the second motor to rotate, that is, drives the fork to rise and fall, so as to realize the function of automatic loading and unloading of the equipment.

[0040] 3. The first protrusion at the bottom of the cargo storage frame cooperates with the fork so that the fork can stably lift the cargo storage frame.
