Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transportation, and in particular relates to a floor-standing elevator. Background Art

[0002] The existing floor-standing elevators have key components for lifting on the support frame. The support frame is generally located at both ends of the conveying platform to stabilize the lifting process of the product. This design prevents the lateral width of the product from exceeding the lateral width of the conveying platform, limiting the flexibility of the equipment when handling wider products. At the same time, the rotating shaft used to drive the lifting on the floor-standing elevator usually spans the conveying platform. If the lateral width of the conveying platform needs to be expanded to handle the lifting of wider products, the rotating shaft must also be extended accordingly. However, the increase in the length of the rotating shaft will lead to a decrease in its strength and rigidity, and there may be a risk of bending or breaking when the load is large or used for a long time, which will affect the normal operation of the floor-standing elevator.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a floor-standing hoist is characterized in that it includes a support frame 1, a lifting platform 2, and a fork frame 3. The support frame 1 is arranged at both ends of the lifting platform 2, and the lifting platform 2 is provided with a horizontal end portion 200 for connecting the support frame 1, and the fork frame 3 is arranged on the lifting platform 2 and extends outward from the horizontal end portion 200; the support frame 1 is provided with a transmission part 4 connected to the lifting platform 2, and a lifting drive device 5 is provided on the outer side of the support frame 1, and the lifting drive device 5 drives the transmission part 4 to move, thereby driving the lifting platform 2 to vertically reciprocate. Specifically, the height range of the fork frame 3 is adjusted to maintain the same horizontal height as the product entrance to facilitate the entry of the product. Preferably, a slidable conveying roller group (not shown in the figure) is provided on the surface of the fork frame 3. If the lateral width of the product to be lifted is within the lateral width range of the lifting platform 2, the conveying roller group is started, and the product to be lifted slides on the fork frame 3 until it reaches the area between the two end support frames 1, that is, the area range of the lifting platform 2; if the lateral width of the product to be lifted is greater than the lateral width range of the lifting platform 2, the conveying roller group provided on the surface of the fork frame 3 does not move, and the product to be lifted stays at the position where the fork frame 3 extends in the direction of the product entrance, and is lifted and lowered together with the lifting platform 2. In this embodiment, the lifting drive device 5 is arranged on the outside of the support frame 1. The outside of the support frame 1 is the end of the support frame 1 away from the lifting platform 2. The lifting drive device 5 is arranged on the outside of the support frame 1 in order not to squeeze the accommodating space of the transmission connection part 20. Figure 1As shown, the lifting drive device 5 is protrudingly provided with a rotating shaft 50 on the support frame 1, which is manifested as a through hole provided on the support frame 1 for the rotating shaft 50 to pass through. In this embodiment, the transmission part 4 is a double sprocket transmission system, which is manifested as a rotatable first transmission part 41 and a second transmission part 42. The first transmission part 41 and the second transmission part 42 are preferably sprocket structures, which are connected by chain transmission to form a closed loop circulation path. In this embodiment, a connecting block (not shown in the figure) connected to the transmission connection part 20 is provided on the chain connecting the first transmission part 41 and the second transmission part 42. The function of the connecting block is to connect the transmission connection part 20 and the transmission part 4. When the transmission part 4 performs double sprocket transmission, the connecting block follows the movement direction of the chain to realize vertical reciprocating motion. Since the connecting block is provided on the transmission connection part 20, and the transmission connection part 20 is a part of the lifting platform 2, the lifting platform 2 realizes vertical reciprocating motion along the movement direction of the chain, that is, the lifting platform 2 realizes lifting motion.

[0022] The fork frame of the utility model is arranged on the lifting platform and extends toward the product entrance. This design makes the lateral width of the product to be lifted no longer limited by the lateral width of the lifting platform. The product to be lifted can be placed on the outwardly extended fork frame and lifted and lowered with the lifting platform, which significantly improves the application scope and flexibility of the utility model. This design does not need to expand the lateral width of the conveying platform, and the rotating shaft does not need to be extended accordingly, so as not to cause its strength and rigidity to decrease, and there is no risk of bending or breaking when the load is large or used for a long time.

[0023] Further, transmission connection parts 20 are horizontally arranged at both ends of the lifting platform 2, and the transmission connection parts 20 are connected to the transmission part 4, and the transmission part 4 drives the transmission connection parts 20 to be lifted and lowered. Specifically, in this embodiment, the transmission connection parts 20 are arranged at both ends of the lifting platform 2 and are arranged parallel to the ground; a connecting block (not shown in the figure) connected to the transmission connection part 20 is provided on the chain connecting the first transmission part 41 and the second transmission part 42, and the function of the connecting block is to connect the transmission connection part 20 and the transmission part 4. When the transmission part 4 performs double sprocket transmission, the connecting block follows the movement direction of the chain to realize vertical reciprocating motion. Since the connecting block is arranged on the transmission connection part 20, and the transmission connection part 20 is a part of the lifting platform 2, the lifting platform 2 realizes vertical reciprocating motion along the movement direction of the chain, that is, the lifting platform 2 realizes lifting motion.

[0024] Further, the transmission part 4 also includes a first transmission part 41 and a second transmission part 42, the lifting drive device 5 is rotatably connected to a rotating shaft 50 in the direction of the lifting platform 2, the first transmission part 41 is rotatably connected to the rotating shaft 50, and the second transmission part 42 is arranged on the support frame 1. Specifically, in this embodiment, the first transmission part 41 and the second transmission part 42 are both sprocket structures; the first transmission part 41 is rotatably connected to the rotating shaft 50, and the lifting drive device 5 is started to drive the rotating shaft 50 to rotate, and the first transmission part 41 is also driven to rotate, and the second transmission part 42 is connected to the first transmission part 41 through a chain transmission system.

[0025] Furthermore, the first transmission part 41 and the second transmission part 42 are in the same vertical plane and are connected to each other by transmission. A lifting area is formed between the first transmission part 41 and the second transmission part 42, and the lifting platform 2 reciprocates vertically in the lifting area. Specifically, in the present embodiment, the transmission connection between the first transmission part 41 and the second transmission part 42 is a chain drive, and preferably, shaft drive or belt drive can also be used. In the present embodiment, the top of the lifting area is the bottom position of the second transmission part 41, and the bottom of the lifting area is the top position of the first transmission part 41. In the present embodiment, the lifting platform 2 is lowered to the position where the first transmission part 41 is approximately in contact, that is, it is lowered to the lowest point. This position is also the critical point where the lifting platform 2 and the first transmission part 41 do not interfere with each other.

[0026] Furthermore, the support frame 1 is provided with a support column 11 perpendicular to the ground, and the lifting platform 2 slides on the support column 11. Specifically, the support frame 1 is hollow inside, and the support column 11 is placed inside the support frame 1 in an embedded form, saving lateral space.

[0027] Further, the transmission connection part 20 also includes an upper transmission connection part 201 and a lower transmission connection part 202, the two ends of the upper transmission connection part 201 are provided with a first guide wheel 2010, the two ends of the lower transmission connection part 202 are provided with a second guide wheel 2020, and the support column 11 includes a first plane 110, and the first guide wheel 2010 and the second guide wheel 2020 slide on the first plane 110. Specifically, the first guide wheel 2010 and the second guide wheel 2020 slide precisely on the first plane 110, ensuring the precise guidance of the transmission connection part 20 in the vertical direction, avoiding the possible deviation and jamming during the transmission process, and this design can reduce friction resistance and improve transmission efficiency. The sliding friction is small, which is conducive to the efficient transmission of power and reduces energy loss.

[0028] Furthermore, the first guide wheel 2010 further includes a third guide wheel 2011, and the second guide wheel 2020 further includes a fourth guide wheel 2021. The third guide wheel 2011 and the fourth guide wheel 2021 slide on adjacent vertical planes of the first plane 110. Specifically, Figure 1 and Figure 3 As shown, the first guide wheel 2010 cooperates with the third guide wheel 2011, and the second guide wheel 2020 cooperates with the fourth guide wheel 2021, which can further ensure the precise guidance of the transmission connection part 20 in the vertical direction.

[0029] Furthermore, the fork frame 3 is movably connected and arranged on the lifting platform 2. Specifically, the fork frame 3 is movably connected, which means that the fork frame 3 can be freely extended and retracted. This design makes it unnecessary for the staff to push the forklift into the lifting platform 2 of the utility model, greatly optimizing the work process, saving manpower, and improving efficiency; if the movably connected fork frame 3 is used with a handling robot, the step of "the product to be lifted waits for the robot to receive" is converted into the step of "letting the robot receive the product to be lifted", that is, from a passive receiving logic to an active receiving logic, which greatly improves the efficiency of handling and receiving.

[0030] Furthermore, the fork frame 3 also includes a first fork frame 31 and a second fork frame 32, and the first fork frame 31 and the second fork frame 32 are arranged in parallel at intervals. Specifically, the first fork frame 31 and the second fork frame 32 are arranged in parallel with each other, and the first fork frame 31 and the second fork frame 32 are fixed on the conveying platform 2 at intervals by fixed connecting parts such as bolts, welded parts or buckles, so as to maintain a parallel relationship and ensure the stable placement of the product. In practical applications, the first fork frame 31 and the second fork frame 32 can be applied to product handling robots in automated warehouses. Specifically, the first fork frame 31 and the second fork frame 32 are connected and moved between warehouse shelves through a hydraulic lifting system to transport products from one shelf to another. According to the size and shape of the product, the interval between the two fork frames is adjusted to ensure the stable handling of the product. At the same time, the anti-skid device on the fork frame can effectively prevent the product from sliding and tilting during the handling process, thereby improving the handling efficiency and safety.

[0031] Furthermore, the rotating shaft 50 further includes a first rotating shaft 501 and a second rotating shaft 502, and a coupling 503 is provided between the first rotating shaft 501 and the second rotating shaft 502. Specifically, in this embodiment, the rotating shaft 50 includes a first rotating shaft 501 and a second rotating shaft 502, and the two shafts are connected together by the coupling 503 to avoid that only one shaft spans the lifting platform 2. By providing the coupling 503 to connect the first rotating shaft 501 and the second rotating shaft 502 together to form the rotating shaft 50, the strength and rigidity of the rotating shaft 50 can be enhanced.

[0032] Next, in order to allow those skilled in the art to better understand this solution, the workflow of the utility model is described here: 1. Startup phase: The operator starts the lifting drive device 5, and the drive device drives the rotating shaft 50 to rotate. The rotating shaft 50 transmits the rotational power to the first transmission part 41 and the second transmission part 42, realizing the rotational movement of the transmission part 4. 2. Power transmission: The rotation of the transmission part 4 is transmitted to the lifting platform 2 through the transmission connection part 20, and the upper transmission connection part 201 and the lower transmission connection part 202 in the transmission connection part 20 slide on the support column 11 through the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel, driving the lifting platform to lift vertically. 3. Product handling: If the lateral width of the product to be lifted is within the lateral width range of the lifting platform 2, the conveyor roller group starts, and the product to be lifted slides on the fork frame 3 until it reaches the area between the two end support frames 1, that is, the area range of the lifting platform 2; if the lateral width of the product to be lifted is greater than the lateral width range of the lifting platform 2, the conveyor roller group set on the surface of the fork frame 3 does not move, and the product to be lifted stays at the position where the fork frame 3 extends in the direction of the product entrance. The product is lifted together with the lifting platform 2 and placed on the fork frame 3. The fork frame includes a first fork frame 31 and a second fork frame 32, which are arranged in parallel at intervals to accommodate products of different widths; the lifting platform is lifted vertically through the transmission system to lift the product to a specified height. 4. Stop and unload: When the lifting platform reaches the predetermined height, the lifting drive device stops working and the lifting platform stops moving. The operator or automated equipment unloads the product from the fork frame to complete a handling process.
