Description

Technical Field

[0001] This utility model relates to the field of material frame stacker technology, and in particular to a chain lifting stacker. Background Technology

[0002] In modern industrial production and logistics warehousing, crate stacking is a common and critical operational step. Traditional crate stacking primarily relies on overhead cranes or other lifting equipment. However, in practice, space is often very limited in many industrial workshops due to the inherent layout of the factory and the compact arrangement of production processes. Overhead cranes and other lifting equipment typically require significant vertical space to install their tracks, and their own operation also requires a certain amount of horizontal space. For example, in multi-story production workshops or low-ceilinged factory buildings, the installation of overhead cranes may be restricted by the overhead structure, preventing them from functioning properly. Furthermore, the extensive movement of the overhead crane during operation may conflict with other production equipment and personnel passageways within the workshop, not only affecting the smooth progress of crate stacking operations but also potentially posing threats to personnel safety and production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a chain-lift stacker that utilizes the space on both sides of the ground rail to flexibly complete the stacking operation of the material frame within a limited space.

[0004] To solve the above-mentioned technical problems, this utility model provides a chain lifting stacker, including a ground rail mechanism, on which the material frame moves horizontally;

[0005] The ground rail mechanism is symmetrically provided with lifting frames on both sides, and each lifting frame is provided with at least one set of lifting mechanisms. The lifting mechanisms move up and down vertically along the lifting frame to lift the material frame on the ground rail mechanism.

[0006] Preferably, the lifting mechanism includes a lifting claw, which is connected to a lifting cylinder via a crank. Under the action of the lifting cylinder, the crank drives the lifting claw to rotate, causing the lifting claw to switch between a lifting state and an avoidance state.

[0007] Preferably, there are two lifting claws, distributed at both ends of the lifting frame and connected in the middle by a first synchronizing rod, so that the two lifting claws can synchronously switch between lifting state and avoidance state under the action of the lifting cylinder.

[0008] Preferably, the lifting mechanism further includes a sliding frame for mounting the lifting claw, the crank, and the lifting cylinder. The sliding frame is connected to the sprocket assembly and, under the action of the sprocket assembly, drives the lifting mechanism to rise and fall vertically.

[0009] Preferably, the sprocket assembly includes a chain, a lifting motor, and multiple steering sprockets. One end of the chain passes over a lower steering sprocket connected to the output shaft of the lifting motor, and the other end passes over an upper steering sprocket and is connected to the sliding frame. Under the action of the lifting motor, the chain is rotated to drive the lifting mechanism to rise and fall in the vertical direction.

[0010] Preferably, there are two upper steering sprockets, distributed at both ends of the lifting frame and connected in the middle by a second synchronizing rod. There are also two chains, each corresponding to one of the two upper steering sprockets. Under the action of the lifting motor, the two chains drive the lifting claws at both ends of the lifting frame to rise and fall synchronously.

[0011] Preferably, the ground track mechanism includes multiple sets of running rollers spaced apart along the moving direction and a translation motor. The running rollers are equipped with sprockets on their connecting rods and are driven by chains. Under the action of the translation motor, the running rollers are driven to rotate by the chains, thereby causing the material frame to move in the horizontal direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Compared to the complex installation process of overhead cranes, this chain-lift stacker crane is much simpler. It doesn't require laying long tracks; the equipment simply needs to be fixed to both sides of the ground rails and the corresponding electrical wiring connected. Its structure is relatively simple, and the installation and debugging of each component is less difficult, requiring no large specialized installation equipment or complex technical support. This not only saves time and costs associated with equipment installation but also allows for rapid deployment, improving production efficiency. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0026] This utility model provides a chain-lift stacker crane; please refer to [link / reference]. Figure 1-4 The system includes a ground rail mechanism 1, on which the material frame 100 moves horizontally; the ground rail mechanism 1 is symmetrically provided with lifting frames 2 on both sides, and the lifting frames 2 are provided with at least one set of lifting mechanisms 3, which move up and down along the vertical direction of the lifting frames 2 to lift the material frame 100 on the ground rail mechanism 1.

[0027] Compared to the complex installation process of overhead cranes, this chain-lift stacker crane is much simpler. It doesn't require laying long tracks; the equipment simply needs to be fixed to both sides of the ground rails and the corresponding electrical wiring connected. Its structure is relatively simple, and the installation and debugging of each component is less difficult, requiring no large specialized installation equipment or complex technical support. This not only saves time and costs associated with equipment installation but also allows for rapid deployment, improving production efficiency.

[0028] For details, please refer to Figure 5-7 The lifting mechanism 3 includes a lifting claw 4, which is connected to a lifting cylinder 6 via a crank 5. Under the action of the lifting cylinder 6, the crank 5 drives the lifting claw 4 to rotate, so that the lifting claw 4 switches between lifting state and avoidance state.

[0029] Furthermore, there are two lifting claws 4, distributed at both ends of the lifting frame 2 and connected in the middle by a first synchronizing rod 7, so that the two lifting claws 4 can synchronously switch between lifting state and avoidance state under the action of the lifting cylinder 6.

[0030] Furthermore, the lifting mechanism 3 also includes a sliding frame 8 for mounting the lifting claw 4, the crank 5, and the lifting cylinder 6. The sliding frame 8 is connected to the sprocket assembly and, under the action of the sprocket assembly, drives the lifting mechanism 3 to rise and fall in the vertical direction.

[0031] In this embodiment, the sprocket assembly includes a chain 9, a lifting motor 10, and a plurality of steering sprockets 11. One end of the chain 9 passes over the lower steering sprocket connected to the output shaft of the lifting motor 10, and the other end passes over the upper steering sprocket and is connected to the sliding frame 8. Under the action of the lifting motor 10, the chain 9 is rotated to drive the lifting mechanism 3 to rise and fall in the vertical direction.

[0032] Furthermore, there are two upper steering sprockets, distributed at both ends of the lifting frame 2 and connected in the middle by a second synchronizing rod 12. There are also two chains 9, corresponding to the two upper steering sprockets respectively. Under the action of the lifting motor 10, the two chains 9 are operated to synchronously drive the lifting claws 4 at both ends of the lifting frame 2 to rise and fall synchronously.

[0033] Specifically, such as Figure 8As shown, the ground track mechanism 1 includes multiple sets of running rollers 13 spaced apart along the moving direction and a translation motor 14. The running rollers 13 are equipped with sprockets on their connecting rods and are driven by chains. Under the action of the translation motor 14, the running rollers 13 are driven to rotate by the chains, thereby causing the material frame 100 to move in the horizontal direction.

[0034] The stacker crane operates in two phases: stacking and dismantling. During stacking, the running rollers 13 of the ground rail mechanism 1 first move the first material frame 100 between the two lifting frames 2. At this time, the lifting claws 4 in the lifting mechanism 3, along with the sliding frame 8, move the chain 9 down to both sides of the material frame 100 under the action of the lifting motor 10. Then, under the action of the lifting cylinder 6, the crank 5 drives the two lifting claws 4 to rotate to a horizontal position, i.e., the lifting state, and insert them into the material frame 100. Subsequently, under the action of the lifting motor 10, the height of one material frame is raised. The running rollers 13 of the ground rail mechanism 1 then move the second material frame 100 between the two lifting frames 2. Then, under the action of the lifting motor 10, the first material frame 100 is placed on the second material frame 100. The above operation is repeated to achieve the stacking of material frames. During the disassembly of the frame, the lifting claw 4 in the lifting mechanism 3, along with the sliding frame 8, operates the chain 9 under the action of the lifting motor 10, causing it to descend to both sides of the second-to-last material frame 100, and lifting the material frame 100 above the second-to-last machine. Then, the running roller 13 of the ground rail mechanism 1 moves the lowest material frame 100, and the above operation is repeated to achieve the disassembly of the material frame.

[0035] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
