The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0023] See also Figures 1 to 7The utility model preferably provides a technical solution: a zinc sheet chain elevator, comprising: a first conveying device 11, used for horizontal feeding of zinc sheet stacks 3; and a vertical lifting device arranged at the end of the first conveying device 11, used for vertical lifting of the zinc sheet stacks 3; the vertical lifting device comprises a frame body 4, a car 9 arranged in the frame body 4, a built-in chain conveying device 10 is installed on the car 9, and the conveying direction of the built-in chain conveying device 10 is consistent with the direction of the first conveying device 11, and is used to receive and convey the zinc sheet stacks 3 on the first conveying device 11; a supporting top plate 12 is arranged on the top of the frame body 4; a driving mechanism 6 is arranged on the supporting top plate 12, and four groups of chain assemblies are connected between the driving mechanism 6 and the car 9, which are used to drive the vertical lifting of the car 9 when the driving mechanism 6 is running; and also includes a counterweight mechanism arranged on the frame body 4, which is used to balance the load weight and reduce the load of the driving mechanism 6.

[0024] In this embodiment, if Figure 1 , 2 As shown in FIG. 3 , the application mainly uses the principle of chain transmission to transfer power from one shaft to another through a chain to realize the operation of the mechanical equipment. The elevator car of the design adopts four sets of chain components, which are driven by the driving mechanism 6 to run synchronously, thereby driving the car to move up and down to complete the vertical transportation of the zinc sheet stack 3;

[0025] Specifically, the frame body 4 is a prior art, such as Figure 1 As shown, it is composed of a rectangular steel pipe, a connecting flange, and a guide rail connecting plate, and is used as a channel for supporting the equipment drive device and lifting the car. The car 9 is composed of a rectangular steel pipe, a chain hanger, a bottom plate, etc. Figure 7 As shown, it is mainly used to support the built-in chain conveyor 10, which is driven by four groups of chain components to move up and down along the guide rails fixed on the frame, so as to realize the load transportation of the elevator. A built-in chain conveyor 10 is arranged at the bottom of the car 9, which is used to receive and convey the zinc sheet stack 3 on the first conveyor 11, so that the zinc sheet stack 3 is located in the middle of the car 9. The built-in chain conveyor 10 here is an existing mature technology, which is composed of a frame, a conveying chain, a driving device, a head wheel device, a tail wheel device, a chain tensioning device, etc., and is installed on the car On the bottom plate of the car 9, after reaching the specified height, the zinc sheet stack 3 is sent out from the car. After that, under the action of the four groups of chain components and the driving mechanism 6, the car 9 is smoothly raised, and combined with the set counterweight mechanism, the motor load is reduced during the operation of the elevator, the load weight is balanced, and the smooth operation of the car is ensured. The zinc sheet stack is sent to the chain conveyor line on the platform through the built-in chain conveyor, and finally the zinc sheet stack is transported to the designated position through the transportation system, which prevents forklift transportation in the working area and effectively reduces the safety risk of personnel.

[0026] Furthermore, the driving mechanism 6 includes a driving motor 611 and a right-angle gear box 613 respectively arranged on both sides of the supporting top plate 12. A connecting shaft 614 runs through the middle of each right-angle gear box 613. Driving sprockets 615 are arranged at both ends of the connecting shaft 614. The output shaft of the driving motor 611 is installed with a spiral bevel gear reduction box 612. Both sides of the spiral bevel gear reduction box 612 are connected to the right-angle gear box 613 at corresponding positions. When the driving motor 611 is working, it can drive the connecting shafts 614 on both sides to rotate.

[0027] By setting the driving mechanism 6, specifically as Figure 3 and 5 As shown, the drive motor 611, the spiral bevel gear reducer 612, and the right-angle shaft gearbox 613 are all existing mature technologies and are not repeated here. When the drive motor 611 is working, due to the connection setting of the spiral bevel gear reducer 612 and the right-angle shaft gearbox 613, the output power of the drive motor 611 can be evenly distributed to the four drive sprockets 615 through the spiral bevel gear reducer 612. The four drive sprockets 615 run synchronously to drive the four groups of chain assemblies to drive the elevator car to move up and down, thereby realizing the lifting and lowering of the car with load.

[0028] Furthermore, each chain assembly includes a drive chain 8, one end of the drive chain 8 engages with and passes through the drive sprocket 615 where the connecting shaft 614 is located and extends to the top of the car 9 to be fixedly connected to the first connecting member 811 where it is located, and the other end of the drive chain 8 engages with and passes through the driven sprocket 813 where the car 9 is located and is fixedly connected to the second connecting member 812 where it is located.

[0029] By setting the chain components, such as Figure 2 , 5 As shown, the elevator car is regarded as a chain link shared by four lifting chains, that is, when the above-mentioned four driving sprockets 615 are driven synchronously, the four groups of chain components at corresponding positions can be driven to engage and transmit, thereby driving the car 9 to rise and fall smoothly.

[0030] Furthermore, the counterweight mechanism includes a counterweight block bracket 7, a first counterweight suspension chain 711 and a second counterweight suspension chain 714 respectively fixedly connected to both sides of the counterweight block bracket 7, and a first transition support wheel 712 and a second transition support wheel 713 arranged on one side of the support top plate 12, the first counterweight suspension chain 711 sequentially meshes with and passes through the first transition support wheel 712 and the second transition support wheel 713 to extend to the third connecting member 911 on the rear side of the car 9 and is fixedly connected thereto, and a third transition support wheel 715 and a fourth transition support wheel 716 arranged on the other side of the support top plate 12, the second counterweight suspension chain 714 sequentially meshes with and passes through the third transition support wheel 715 and the fourth transition support wheel 716 to extend to the third connecting member 911 on the front side of the car 9 and is fixedly connected thereto.

[0031] In the design of the counterweight mechanism, Figure 2 , 3 As shown in and 5, the weight of the counterweight bracket 7 can be adjusted by the number of stacked counterweights; the counterweight bracket 7 is suspended by the first counterweight suspension chain 711 and the second counterweight suspension chain 714 on both sides for counterweighting, the second counterweight suspension chain 714 meshes and passes through the third transition support wheel 715 and the fourth transition support wheel 716 to extend to the front side of the car 9 and is fixed thereto, while the first counterweight suspension chain 711 meshes and passes through the first transition support wheel 712 and the second transition support wheel 713 to extend to the rear side of the car 9 and is fixed thereto, so that the front and rear sides of the car 9 are both affected by the force of the counterweight bracket 7, which is used to reduce the motor load during equipment operation, balance the load weight, and ensure smooth operation of the car.

[0032] Furthermore, a maintenance safety guardrail 5 is also provided on the frame body 4 to facilitate the staff to place it on the top of the frame body 4 for maintenance. The maintenance safety guardrail 5 mainly includes a guardrail and a climbing ladder on one side.

[0033] Furthermore, a support platform 1 is provided on the side of the frame body 4 away from the first conveying device 11, and a second conveying device 2 is provided on the top of the support platform 1 for receiving the zinc sheet stack 3 again and conveying it.
