Description

Technical Field

[0001] The utility model relates to the technical field of industrial hoists, in particular to a double-layer hoist used for industrial heavy-load. Background Art

[0002] At present, the gearbox, front axle, rear axle, front frame, rear frame, and boom assembly on the loader assembly line are placed on the skid and transported on the roller line. However, some process positions require a reciprocating elevator to pick up the goods on the lower level and then lift them to the upper conveyor line. However, the elevator must first put the empty skid returning from the upper conveyor line into the elevator, and then the elevator will send the skid with goods into the line body. The empty skid in the elevator is then returned to the lower conveyor line through the elevator for reflux. Since the product size is compatible with many models and the weight of the object is overweight, the elevator requires multiple functional actions. Currently, ordinary elevators only have a car with a single-layer conveying function; the size is not suitable for existing workpieces; the elevator action process is also not suitable. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the product size is compatible with many models, the weight of the object is overweight, and the elevator needs multiple functional actions. At present, ordinary elevators only have a car with a single-layer conveying function; the size is not suitable for existing workpieces, and a double-layer elevator for industrial heavy-duty is proposed.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A double-layer elevator for industrial heavy loads is designed, including a frame assembly and a double-layer hanging basket. A lifting drive device is installed on the upper end surface of the frame assembly. The outer wall of the end of the output shaft of the lifting drive device is fixedly connected with a sprocket. The outer wall of the sprocket is meshed and wound with a lifting chain assembly. One side of the lifting chain assembly is fixedly connected to the double-layer hanging basket, and the other side of the lifting chain assembly is fixedly connected to the double-layer counterweight assembly. Roller conveyor line assemblies are installed on two inner walls of the double-layer counterweight assembly.

[0006] Preferably, a safety guardrail is fixedly connected to the outer ring of the upper end of the frame assembly, and a safety ladder is installed on one side of the safety guardrail.

[0007] Preferably, elevator guide rails are fixedly connected to both sides of the inner wall of the frame assembly.

[0008] Preferably, guide shoe assemblies are installed on the left and right sides of the upper end of the double-layer counterweight assembly.

[0009] The utility model proposes a double-deck elevator for industrial heavy-duty use, which has the following beneficial effects:

[0010] Through the coordination among the lifting drive device, lifting chain assembly, double-layer hanging basket and roller conveyor line assembly, the variable frequency speed control motor in the lifting drive device is controlled to make the lifting car, i.e. the double-layer hanging basket, reciprocate up and down. The lifting car is equipped with a double-layer conveying mechanism, i.e. the roller conveyor line assembly, and the conveyed objects automatically enter the double-layer hanging basket of the elevator. In this case, the elevator car (hanging basket) is changed into a double-layer, and the elevator can first connect the cargo skid of the conveyor line and lift it to the upper layer. The empty skid returning the line body is first connected to the elevator, and the elevator then sends the cargo skid into the line body and then the elevator descends to the lower layer to send the empty skid back to the conveyor line. This type of elevator has the characteristics of advanced control, reliable performance, and high positioning accuracy of the lifting car. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Embodiment 1:

[0016] See attached Figure 1-2 : In the present embodiment, a double-layer elevator for industrial heavy loads includes a frame assembly 1 and a double-layer hanging basket 2, a lifting drive device 6 is installed on the upper end surface of the frame assembly 1, a sprocket 7 is fixedly connected to the outer wall of the output shaft end of the lifting drive device 6, a lifting chain assembly 10 is meshed and wound around the outer wall of the sprocket 7, one side of the lifting chain assembly 10 is fixedly connected to the double-layer hanging basket 2, and the other side of the lifting chain assembly 10 is fixedly connected to the double-layer counterweight assembly 8, and roller conveyor line assemblies 9 are installed on the inner wall of the double-layer counterweight assembly 8. A safety guardrail 5 is fixedly connected to the outer ring of the upper end of the frame assembly 1, and a safety ladder 4 is installed on one side of the safety guardrail 5. Elevator guide rails 3 are fixedly connected to both sides of the inner wall of the frame assembly 1, and guide shoe assemblies 11 are installed on the left and right sides of the upper end of the double-layer counterweight assembly 8;

[0017] Change the elevator car (basket) to a double-layer one. The elevator can first connect the conveyor line's cargo skid, lift it to the upper layer, first connect the empty skid of the line body back to the elevator, and then the elevator sends the cargo skid into the line body. Then the elevator descends to the lower layer to send the empty skid back to the conveyor line.

[0018] Through the cooperation among the lifting drive device 6, the lifting chain assembly 10, the double-layer hanging basket 2 and the roller conveyor line assembly 9, the variable frequency speed control motor in the lifting drive device 6 is controlled to make the lifting car, i.e. the double-layer hanging basket 2, reciprocate up and down. The lifting car is equipped with a double-layer conveying mechanism, i.e. the roller conveyor line assembly 9, and the conveyed objects automatically enter the double-layer hanging basket 2 of the elevator. In this case, the elevator car (hanging basket) is changed into a double-layer, and the elevator can first connect the cargo skid of the conveyor line and lift it to the upper layer. The empty skid that returns the line body is first connected to the elevator, and the elevator then sends the cargo skid into the line body and then the elevator descends to the lower layer to send the empty skid back to the conveyor line. This type of elevator has the characteristics of advanced control, reliable performance, and high positioning accuracy of the lifting car.

[0019] Working principle:

[0020] When it is needed to be used in an industrial heavy-load double-deck elevator, it is driven by the lifting chain assembly 10, and the frequency conversion speed control motor in the lifting drive device 6 is controlled to make the lifting car, i.e., the double-deck hanging basket 2, reciprocate up and down. The lifting car is equipped with a double-deck conveying mechanism, i.e., a roller conveyor line assembly 9, and the conveyed objects automatically enter the double-deck hanging basket 2 of the elevator. In this case, the elevator car (hanging basket) is changed into a double-deck, and the elevator can first connect the cargo skid of the conveyor line and lift it to the upper layer. The empty skid that returns the line body is first connected to the elevator, and the elevator then sends the cargo skid into the line body and then the elevator descends to the lower layer to send the empty skid back to the conveyor line. This type of elevator has the characteristics of advanced control, reliable performance, and high positioning accuracy of the lifting car.
