Description

Technical Field

[0001] The utility model relates to the technical field of synchronous lifting of products, in particular to a mechanical mobile synchronous mechanism. Background Art

[0002] The synchronous mobile lifting mechanism, also known as a lifting platform, is a lifting device that lifts people or goods to a certain height, and is used for vertical transportation in logistics systems such as factories and automatic warehouses.

[0003] Existing synchronous lifting mechanisms are mostly composed of large components or single-powered units. These components (which rise with power and descend with weight) are often affected by uneven loads, component manufacturing and installation precision, and transmission component wear, leading to asynchronous movement. This can cause noise and component jamming, resulting in low product lifting and transportation efficiency.

[0004] Therefore, it is necessary to provide a mechanical mobile synchronization mechanism to solve the above problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the present invention is to provide a mechanical mobile synchronization mechanism with a simple structure and high applicability, which can improve the product lifting efficiency while also reducing the maintenance frequency of the mechanism.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a mechanical mobile synchronization mechanism, including a mobile platform, a pulley group and a flexible connector group; the flexible connector group includes flexible connector 1 and flexible connector 2, and both flexible connector 1 and flexible connector 2 include a lifting end and a pull-down end, and the pull-down end is connected to one side of the mobile platform. The lifting end passes around the pulley group upward and passes through the bottom of the mobile platform and is connected to the other opposite side of the mobile platform. The lifting end and the pull-down end on the flexible connector 1 and the lifting end and the pull-down end on the flexible connector 2 are staggered.

[0007] Furthermore, the invention further comprises a support structure, wherein the support structure comprises a symmetrically arranged left support and a right support, wherein the pulley assembly comprises a winding pulley and a guide pulley, wherein the winding pulley is arranged at the top of the left support and the right support, and the guide pulley is arranged at the bottom of the left support and the right support. The two symmetrically arranged supports can support the setting of the pulley assembly, facilitating the subsequent vertical winding of the portion on the first flexible connector and the second flexible connector.

[0008] Furthermore, the winding pulleys on the top of the left bracket and the guide pulleys on the bottom of the right bracket are respectively located at the same height in the vertical direction, so as to ensure that the subsequent winding of the flexible connector group can achieve stable synchronous lifting and lowering movement of the mobile platform.

[0009] Adjust the position of the mobile platform in the vertical direction. When the mobile platform needs to rise, pull the lifting ends of the flexible connector 1 and the flexible connector 2 upward. With the cooperation of the pulley group, the pulling ends of the flexible connector 1 and the flexible connector 2 will synchronously drive the mobile platform to move upward; when the mobile platform needs to descend, pull the pulling ends of the flexible connector 1 and the flexible connector 2 downward. With the cooperation of the pulley group, the lifting ends of the flexible connector 1 and the flexible connector 2 will synchronously drive the connected mobile platform to move downward.

[0010] Furthermore, the portions of the flexible connector 1 and the flexible connector 2 between the lifting end and the guide pulley or the pulling end and the winding pulley are both vertically arranged, so that when the lifting end or the pulling end is lifted upward or pulled downward, the mobile platform can rise or fall smoothly.

[0011] Further, each of the pulley blocks is connected to the left bracket or the right bracket via a pulley bracket. The pulley bracket is provided to facilitate the winding of the flexible connector 1 and the flexible connector 2.

[0012] Furthermore, two fixed connectors are provided on each of the two side surfaces in the width direction of the mobile platform. The lifting end on the flexible connector 1 and the lowering end on the flexible connector 2 are connected to the two fixed connectors on the same side, and the lowering end on the flexible connector 1 and the lifting end on the flexible connector 2 are connected to the two fixed connectors on the same side. The provision of fixed connectors facilitates the connection of the flexible connector 1 and the flexible connector 2 to the mobile platform.

[0013] Furthermore, the lifting end and the pull-down end are respectively provided with an adjustment connection assembly, and the adjustment connection assembly includes a connection seat fixed to the lifting end or the pull-down end, and a limiting groove for the bolt to be placed upside down is provided on the top of the connection seat, and the stud end on the bolt passes through the fixed connection piece and is locked with it by a locking nut. The limiting groove is a convex structure, which can well limit the nut end on the bolt, so that the bolt always remains in a vertical state. By adjusting the position of the stud end of the bolt and the fixed connection piece, the flexible connection piece can always be in a tensioned state, and the tensioning force of flexible connection piece one and flexible connection piece two can always be kept consistent. At the same time, the posture of the mobile platform can also be fine-tuned so that it is always in a stable state after being lifted by the two flexible connections, thereby ensuring the subsequent work efficiency of driving the parts to be lifted.

[0014] Beneficial effects of the utility model:

[0015] 1. In the present invention, the support mechanism, pulley assembly, fixed connector, flexible connector and mobile platform cooperate with each other. Both ends of the flexible connector are connected to the mobile platform to form a closed loop structure. When one end of the flexible connector is pulled up or down, the other end can also move up or down under the action of the pulley assembly, that is, the mobile platform can move up or down. This structure is simple and has high applicability, which can effectively improve the lifting efficiency of the product.

[0016] 2. The pulley block and the flexible connector in the present invention are both purely mechanical structures. The product can be lifted or lowered without the need for transmission components, which effectively avoids parts noise and parts jamming, thereby reducing the maintenance frequency of the mechanism and the company's transportation costs.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0023] See attached Figures 1 to 4 As shown, a mechanical mobile synchronization mechanism in this embodiment includes a mobile platform 3, a pulley group 2 and a flexible connection group. The surface of the mobile platform 3 is used to place multiple products that need to be lifted. The pulley group 2 can support, tension and guide the flexible connection group arranged around it, making it easy to pull the flexible connection group to adjust the synchronous lifting of the mobile platform 3.

[0024] The flexible connector group includes a flexible connector 1 7 and a flexible connector 2 8. Both the flexible connector 1 7 and the flexible connector 2 8 include a lifting end 9 and a pulling end 10. The pulling end 10 is connected to one side of the mobile platform 3. The lifting end 9 passes upward around the pulley block 2, passes under the mobile platform 3, and connects to the other opposite side of the mobile platform 3. The lifting end 9 and the pulling end 10 on the flexible connector 1 7 are staggered with the lifting end 9 and the pulling end 10 on the flexible connector 2 8. By providing two flexible connectors, the mobile platform 3 is always kept stable during the synchronous lifting process, and is prevented from tilting and causing the products placed thereon to fall.

[0025] When the lifting platform needs to descend, the pull-down ends 10 on the flexible connector 1 7 and the flexible connector 2 8 are pulled downward at the same time. At this time, the lifting ends 9 corresponding to the two pull-down ends 10 will also move downward with the cooperation of the pulley group 2, thereby realizing the stable downward movement of the entire mobile platform 3; conversely, as long as the two lifting ends 9 are lifted upward at the same time, then with the cooperation of the pulley group 2, the two pull-down ends 10 can also synchronously drive the side of the mobile platform 3 connected to it to move upward, thereby realizing the stable upward movement of the entire mobile platform 3.

[0026] The above-mentioned synchronous lifting mechanism has a simple structure and high applicability, and can effectively improve the lifting efficiency of the product; and the pulley group 2 and the flexible connector 1 and the flexible connector 2 8 are all purely mechanical structures, and the product can be lifted and lowered without the need for transmission components, etc., which can effectively avoid parts noise and parts jamming, thereby effectively reducing the maintenance frequency of the mechanism and reducing the company's transportation costs.

[0027] Specifically, the flexible connection member is a belt, a steel rope or a chain.

[0028] The apparatus further includes a support structure 1, which includes a symmetrically arranged left support 11 and a right support 12. The pulley assembly 2 includes a winding pulley 21 and a guide pulley 22. The winding pulley 21 is arranged at the top of the left support 11 and the right support 12, and the guide pulley 22 is arranged at the bottom of the left support 11 and the right support 12. The two symmetrically arranged supports can support the setting of the pulley assembly 2, facilitating the subsequent vertical winding of the portion on the flexible connector 1 7 and the flexible connector 2 8.

[0029] The winding pulleys 21 at the top of the left bracket 11 and the guide pulleys 22 at the bottom of the right bracket 12 are respectively located at the same height in the vertical direction to ensure that the subsequent winding of the flexible connector group can achieve stable synchronous lifting and lowering movement of the mobile platform 3.

[0030] See attached Figure 1In some embodiments, during installation, the lifting end 9 of the flexible connector 7 is connected to the left side of the mobile platform 3, and the pulling end 10 passes downward around the guide pulley 22 at the bottom of the left bracket 11, and then moves horizontally toward the direction close to the right bracket 12 and passes around the guide pulley 22 at the bottom of the right bracket 12, and then passes upward along the height direction of the right bracket 12 around the winding pulley 21 at the top of the right bracket 12, and finally moves downward and is fixed on the right side of the mobile platform 3. The winding and connection operations of the flexible connector 2 8 are consistent with those of the flexible connector 7.

[0031] Adjust the position of the mobile platform 3 in the vertical direction. When the mobile platform 3 needs to rise, pull the lifting end 9 on the flexible connector 1 7 and the flexible connector 2 8 upwards. With the cooperation of the pulley group 2, the pull-down end 10 of the flexible connector 1 7 and the flexible connector 2 8 will synchronously drive the mobile platform 3 to move upward; when the mobile platform 3 needs to descend, pull the pull-down end 10 of the flexible connector 1 7 and the flexible connector 2 8 downwards. With the cooperation of the pulley group 2, the lifting end 9 of the flexible connector 1 7 and the flexible connector 2 8 will synchronously drive the mobile platform 3 connected thereto to move downward.

[0032] The parts of the flexible connector 1 7 and the flexible connector 2 8 between the lifting end 9 and the guide pulley 22 or the pull-down end 10 and the winding pulley 21 are both vertically arranged so that when the lifting end 9 or the pull-down end 10 is lifted up or pulled down, the mobile platform 3 can be smoothly raised or lowered.

[0033] In some embodiments, the portions of the flexible connector 1 7 and the flexible connector 2 8 located between the two guide pulleys 22 are arranged horizontally and parallel to each other.

[0034] Each of the pulley blocks 2 is connected to the left bracket 11 or the right bracket 12 via a pulley bracket 4. The pulley bracket 4 facilitates the winding of the flexible connector 1 7 and the flexible connector 2 8.

[0035] Two fixed connectors 5 are provided on each side of the mobile platform 3 in the width direction. The lifting end 9 on the flexible connector 1 7 and the lowering end 10 on the flexible connector 2 8 are connected to the two fixed connectors 5 on the same side. The lowering end 10 on the flexible connector 1 7 and the lifting end 9 on the flexible connector 2 8 are connected to the two fixed connectors 5 on the same side. The provision of fixed connectors 5 facilitates the connection of flexible connectors 1 7 and 2 8 to the mobile platform 3.

[0036] In some embodiments, the two fixed connectors 5 on the same side are a long connector 51 and a short connector 52, wherein the lifting end 9 is connected to the long connector 51, and the pull-down end 10 is connected to the short connector 52, so that the part between the lifting end 9, the pull-down end 10 and the pulley group 2 on the flexible connector group is always in a vertical state, ensuring that the mobile platform 3 will not move unsteadily due to the tilt of the flexible connector.

[0037] It should be noted that the two sides of the mobile platform 3 connected to the flexible connector 1 7 and the flexible connector 2 8 are opposite surfaces. This ensures that the mobile platform 3 remains horizontal and stable during its up and down movement, thereby ensuring the efficiency of its synchronous lifting and transportation. In addition, the flexible connectors are not limited to connecting only to the side surfaces of the mobile platform 3; they can also be connected to the upper and lower surfaces, as long as the lifting ends 9 and lower pull-down ends 10 of the flexible connector 1 7 and the flexible connector 2 8 are connected to the mobile platform 3 at staggered positions.

[0038] The lifting end 9 and the pull-down end 10 are respectively provided with an adjustment connection assembly 6, and the adjustment connection assembly 6 includes a connection seat 61 fixed to the lifting end 9 or the pull-down end 10. The top of the connection seat 61 is provided with a limit groove 62 for the bolt 63 to be placed upside down. The stud end on the bolt 63 passes through the fixed connection member 5 and is locked with it by a locking nut. The limit groove 62 has a convex structure, which can well limit the nut end on the bolt 63, so that the bolt 63 always remains in a vertical state. By adjusting the position of the stud end of the bolt 63 and the fixed connection member 5, the flexible connection member can always be in a tensioned state, and the tension force of the flexible connection member 1 7 and the flexible connection member 2 8 is always consistent. At the same time, the posture of the mobile platform 3 can also be fine-tuned so that it is always in a stable state after being lifted by the two flexible connections, thereby ensuring the subsequent work efficiency of driving the parts to be lifted.

[0039] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
