Description

A steel platform inlet and outlet lifting mechanism Technical Field

[0001] This utility model relates to chain transport structures, and in particular to a lifting mechanism for the inlet and outlet of a steel distribution platform. Background Technology

[0002] The steel sorting platform consists of an input roller conveyor group, a horizontal conveyor chain group, and an output roller conveyor group. A swing input chain group is located between the input roller conveyor group and the horizontal conveyor chain group, and a swing output chain group is located between the horizontal conveyor chain group and the output roller conveyor group. Both the swing input chain group and the swing output chain group include a conveyor chain and a lifting mechanism. The steel sorting platform is the only channel for distributing straightened profiles to the subsequent packaging process, playing a crucial role in controlling the production rhythm and maintaining smooth production. The existing lifting mechanism, as shown in Figure 2, includes a slanted hydraulic cylinder, a 7-shaped rocker arm, a linkage plate, a lifting connecting rod, a lifting beam, and a hydraulic cylinder extension / retraction mechanism. The 7-shaped rocker arm swings along the axis, pushing the connecting rod to lift and lower the lifting beam, thus realizing the up-and-down swinging motion of the conveyor chain. Due to the power limitations of the inclined hydraulic cylinder, it can only be divided into two groups. The flow rate of the two inclined hydraulic cylinders is controlled to keep the two groups horizontal. When conveying ultra-long steel, there is no mechanical linkage between the two groups, resulting in asynchronous lifting. Because the two swing chains are not synchronized, the profiles cannot be conveyed backward from the roller conveyor, get caught on the corners of the roller conveyor guard plate, and bend the profiles. In some cases, the steel running on the conveyor roller conveyor may even break due to the delayed lifting of some swing chains. Summary of the Invention

[0003] The purpose of this utility model is to provide a lifting mechanism for the inlet and outlet of a steel distribution platform, which solves the problem of asynchronous lifting beams in existing lifting mechanisms for steel distribution platforms.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a steel distribution platform inlet and outlet lifting mechanism, including an input roller conveyor group, a horizontal conveyor chain group, and an output roller conveyor group. A swing input chain group is arranged between the input roller conveyor group and the horizontal conveyor chain group, and a swing output chain group is arranged between the horizontal conveyor chain group and the output roller conveyor group. Both the swing input chain group and the swing output chain group include a conveyor chain and a lifting mechanism. The conveyor chain is arranged on a chain arm, and multiple chain arms are evenly spaced and arranged in parallel, with a column at one end of each chain arm. One end of the chain arm is rotatably connected to the column. The lifting mechanism includes a crossbeam and multiple brackets arranged on the crossbeam. The brackets are arranged corresponding to the chain arms, and the chain arms are supported on the brackets. Multiple hydraulic cylinders are arranged below the crossbeam, and the extension rods of the hydraulic cylinders are connected to the crossbeam.

[0006] Preferably, the card holder is provided with a limiting groove, and the two sides of the crossbeam are provided with sliders corresponding to the limiting grooves.

[0007] Preferably, multiple hydraulic cylinders are connected to the same flow divider valve.

[0008] Preferably, photoelectric limit switches are provided at both ends of the crossbeam, and the output end of the photoelectric limit switches is connected to the display.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model discloses a lifting mechanism for the inlet and outlet of a steel distribution platform. It includes a continuous horizontal beam, a dual hydraulic cylinder for direct jacking, and a slotted connection between the beam and the chain arms, allowing adjustment of the actual height of each chain arm according to production needs.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship 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 technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] As shown in Figure 1, the system includes an input roller conveyor group 1, a horizontal conveyor chain group 2, and an output roller conveyor group 3. A swing input chain group 4 is provided between the input roller conveyor group 1 and the horizontal conveyor chain group 2, and a swing output chain group 5 is provided between the horizontal conveyor chain group 2 and the output roller conveyor group 3. At least a portion of the swing input chain group 4 and the swing output chain group 5 extend into the input roller conveyor group 1 and the output roller conveyor group 3, respectively. Therefore, after the steel is straightened, it is placed on the input roller conveyor. After the swing input chain group 4 is lifted, it is transported to the horizontal conveyor chain group 2. After being transported to the other end of the horizontal conveyor chain group 2, the steel is distributed to the output roller conveyor group 3 by the lifting of the swing output chain group 5. The output roller conveyor group 3 then transports the steel to the subsequent packaging table.

[0026] As shown in Figures 3 and 4, both the oscillating input chain group 4 and the oscillating output chain group 5 include a conveyor chain 6 and a lifting mechanism. The conveyor chain 6 is mounted on the chain arm 7, and transport sprockets 61 are provided on both sides of the upper end of the chain arm 7. The multiple chain arms 7 of the conveyor chain 6 are evenly spaced and parallel, and each chain arm 7 has a column 8 at one end. One end of the chain arm 7 is rotatably connected to the column 8. The other end of the chain arm 7 of the oscillating input chain group 4 and the oscillating output chain group 5 extends into the input roller group 1 and the output roller group 3, respectively. In this way, the chain arm 7 can rotate around the column 8 to achieve lifting and lowering on one side, transporting the steel to the chain arm 7, thereby realizing the transfer of the steel.

[0027] As shown in Figure 5, the lifting mechanism includes a crossbeam 9 and multiple mounting brackets 11 arranged on the crossbeam 9. Each mounting bracket 11 corresponds to a chain arm 7, which is mounted on the mounting bracket 11. Multiple hydraulic cylinders 10 are arranged below the crossbeam 9, and the extension rods of the hydraulic cylinders 10 are connected to the crossbeam 9. When the hydraulic cylinders 10 are activated, their extension rods drive the crossbeam 9 to rise. During the rise, since the chain arms 7 are mounted on the mounting brackets 11 of the crossbeam 9, one end of the crossbeam 9 also rises and is confined to the corresponding mounting bracket 11. Since multiple chain arms 7 are mounted on the same crossbeam 9, the lifting height of the multiple chain arms 7 is consistent. Therefore, when the steel is transported on the chain arms 7, there will be no jamming problem caused by unevenness.

[0028] In this example, two hydraulic cylinders 10 are set up and connected to the same flow divider valve. In this way, the fluid flow of the hydraulic cylinders 10 can be controlled so that the flow of the two hydraulic cylinders 10 is the same and the lifting height is the same, so that the crossbeam 9 will be in a horizontal state.

[0029] The card holder 11 is provided with a limiting groove. The two sides of the crossbeam 9 are provided with sliders 12 corresponding to the positions of the inner walls of the limiting groove. The sliders 12 at the bottom of the limiting groove can be raised according to production needs. The sliders 12 can slide along the groove rail of the card holder 11. In this way, when lifting, the sliding of the sliders 12 can effectively avoid damage to the chain arm 7.

[0030] As shown in Figure 3, photoelectric limit switches are installed at both ends of the crossbeam 9, and the output of the photoelectric limit switches is connected to the display. The photoelectric limit switches determine the lifting height of the crossbeam 9 and then transmit the result to the display. After the operator observes whether the height position is appropriate, they can adjust the flow valve of the hydraulic cylinder 10 to control the lifting height of the crossbeam 9.

[0031] In this example, the existing two groups are combined into one group, and both are lifted by the crossbeam 9. The crossbeam 9 has a simple structure and is easy to maintain. The lifting action is more direct and efficient through the hydraulic cylinders 10 with two flow valves, which improves production efficiency. At the same time, the height can be adjusted separately according to the usage of the chain arm 7, making it more adaptable.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
