[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-level elevator that solves the above-mentioned technical problems existing in the prior art.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0010] A multi-level elevator includes a support body, a car assembly, and a tensioning assembly. The support body has an overall frame structure, and a space for accommodating the car assembly is formed inside the frame along the vertical direction.

[0011] A guide rail is provided vertically on the inner side of the support body;

[0012] The car assembly includes a drive motor at the bottom, conveyor chains on both sides, and an inverted U-shaped bracket. The drive motor drives the conveyor chains on both sides to move via a transmission shaft. The conveyor chains are distributed in parallel along the horizontal direction, and the conveyor chains lift the four-way trolley and transfer it in the horizontal direction.

[0013] The inverted U-shaped bracket is positioned above the car assembly, and limiting rollers are provided on both sides of the inverted U-shaped bracket. The limiting rollers move up and down along the extension direction of the guide rail.

[0014] The tensioning assembly is located at the top of the support body and includes a tensioning motor and a tensioning belt. The tensioning belt extends downward from the tensioning motor to the car assembly, and the entire car assembly is stretched by the tensioning belt and moves up and down along the extension direction of the guide rail.

[0015] Furthermore, the guide rail has an overall T-shaped structure, and the limiting rollers are two sets that are symmetrical to each other. The two sets of symmetrical limiting rollers form a clamping and limiting position on both sides of the T-shape where the guide rail is located.

[0016] Furthermore, a guide roller is provided on the side where the inverted U-shaped bracket is located, so that the guide roller is located on the T-shaped end face of the guide rail and rolls, and the guide roller rotates on its own; and the guide roller is located at the vertical central axis position where the two sets of limiting rollers are located.

[0017] Furthermore, adjusting screws are provided on both sides of the guide roller to adjust the width of the guide roller extending outward.

[0018] Furthermore, a limiting baffle is provided on the outer side of the conveyor chain along the transmission direction, and the two sides of the limiting baffle are bent outward.

[0019] Furthermore, a tank drag chain is installed inside the cavity where the support body is located, and the car body assembly is moved vertically synchronously by the tank drag chain.

[0020] Furthermore, a counterweight is provided on the side where the tensioning component is located.

[0021] Furthermore, two sets of symmetrical hollow guide rails are provided on one side of the support body, so that the two sides of the counterweight slide along the extension direction of the hollow guide rails and move up and down synchronously.

[0022] Furthermore, a protective net is installed on one side of the support body where the counterweight is located, and the protective net forms an area for the counterweight to move in the vertical direction.

[0023] The beneficial effects of this utility model are:

[0024] 1. This device ensures synchronized movement between multiple conveyor chains through precise coordination between the drive motor and the conveyor chain. This synchronization avoids the risk of items tilting or falling during transfer, thus improving transfer efficiency.

[0025] 2. This device employs a car assembly design that combines guide rails and limiting rollers to ensure the stability of the car during its vertical movement. This design effectively prevents items from tilting or falling due to instability, thus improving the safety of item transport.

[0026] 3. This device incorporates adjusting screws in the guide roller design, enabling timely intervention to address guide roller wear and maintain tight contact with the guide rail. This convenient adjustment mechanism significantly reduces maintenance costs and extends the equipment's lifespan. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figure 1As shown, this embodiment of the utility model provides a multi-level elevator, including a support body 1, a car assembly 2, and a tensioning assembly 3. The support body 1 has an overall frame structure. This frame structure design allows for more flexible use of vertical and horizontal space, adapting to different working environments, especially in space-constrained warehousing and logistics settings. The frame structure also forms a space along the vertical direction to accommodate the car assembly 2, enabling vertical movement of the car assembly 2. The left and right sides of the support body 1 are separated by a grid, while the front and rear sides are open, facilitating the entry and exit of four-way trolleys to the location of the car assembly 2.

[0035] like Figure 2 , Figure 3 , Figure 4 As shown, the car assembly 2 includes a drive motor 21 at the bottom, conveyor chains 22 on both sides, and an inverted U-shaped bracket 23. The drive motor 21 drives the conveyor chains 22 on both sides to move through a transmission shaft 211 (that is, the rotation of the two sets of conveyor chains 22 can be synchronized by setting a set of transmission shafts 211, so when the four-way trolley contacts the conveyor chain 22, synchronous transmission can be formed, avoiding tipping in an asynchronous state). The conveyor chains 22 are distributed parallel to each other in the horizontal direction, and the conveyor chains 22 form a lifting and horizontal transfer of the four-way trolley. In order to form a lifting of the four-way trolley, the conveyor chains 22 are set at a certain height from the bottom of the car assembly 2 (this equipment can seamlessly connect with the four-way trolley, adapt to the needs of different types of goods transfer, enhance the overall flexibility and adaptability of the system, and meet the diversified needs of modern logistics systems).

[0036] A guide rail 11 is set vertically on the inner side of the support body 1. The guide rail 11 has a T-shaped structure (this structure can provide high support strength in the vertical direction). An inverted U-shaped support 23 is set above the car assembly 2, and limiting rollers 231 are set on both sides of the inverted U-shaped support 23. The limiting rollers 231 move up and down along the extension direction of the guide rail 11. The limiting rollers 231 are two sets that are symmetrical to each other. The two sets of symmetrical limiting rollers 231 form a clamping and limiting position on both sides of the T-shaped guide rail 11. Since the two sides are symmetrically arranged, it can avoid transmission instability in the front and back directions when moving up and down in the vertical direction.

[0037] Meanwhile, a guide roller 232 is provided on the side where the inverted U-shaped bracket 23 is located, so that the guide roller 232 is located on the T-shaped end face of the guide rail 11 and rolls, and the guide roller 232 rotates on its own, so that the guide roller 232 can directly contact the T-shaped surface where the guide rail 11 is located, and the guide roller 232 is located at the vertical center axis where the two sets of limiting rollers 231 are located, so as to achieve smooth movement of the car assembly 2 in the vertical direction.

[0038] Due to the rolling wear between the guide roller 232 and the guide rail 11 over a long period of time, a certain wear gap will be generated. Adjusting screws 233 are set on both sides of the guide roller 232. The width of the guide roller 232 extending outward is adjusted by adjusting the screws 233, so that the guide roller 232 continues to roll in contact with the surface of the guide rail 11.

[0039] A limit baffle 221 is provided on the outer side of the conveyor chain 22 along the transmission direction, and the two sides of the limit baffle 221 are bent outward. This design will not affect the obstruction of the four-way trolley entering the car assembly 2.

[0040] A tank drag chain 12 is installed inside the cavity where the support body 1 is located. The tank drag chain 12 synchronously moves the car body assembly 2 in the vertical direction. Therefore, when used in conjunction with the tensioning assembly 3, the stability during vertical movement is greatly improved.

[0041] The tensioning assembly 3 is located at the top of the support body 1 and includes a tensioning motor 31 and a tensioning belt 32. The tensioning belt 32 extends downward from the tensioning motor 31 to the car assembly 2 (in order to improve its stability, tensioning belts 32 are provided around the car assembly 2). The tensioning belt 32 stretches the entire car assembly 2 and moves up and down along the extension direction of the guide rail 11.

[0042] like Figure 5As shown, a counterweight 33 is installed on the side where the tensioning assembly 3 is located. The counterweight 33 effectively balances the load of the hoist and reduces the workload of the motor. Through the counterweight, the hoist can maintain stability during lifting and lowering, reducing energy consumption. Two sets of symmetrical hollow guide rails 13 are installed on one side of the support body 1, allowing the two sides of the counterweight 33 to slide along the extension direction (i.e., the vertical direction) of the hollow guide rails 13 and move up and down synchronously, ensuring the stability of the counterweight 33 when moving in conjunction with the tensioning assembly 3. A protective net 301 is installed on one side of the support body 1 where the counterweight 33 is located, enclosing the area where the counterweight 33 moves in the vertical direction. This arrangement also provides safety assurance during the transfer of the car assembly 2 and protects the safety of surrounding personnel, reducing potential safety hazards caused by equipment operation. This design is particularly important in busy industrial environments, ensuring the safety of operators.

[0043] The optimization of the overall equipment design has significantly improved the efficiency of the multi-level elevator in the transfer of goods, enabling it to respond quickly to logistics needs, reduce the waiting time of goods during the transfer process, and improve overall work efficiency.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
