Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to a hydraulic support transfer system. Background Technology

[0002] Hydraulic supports are core equipment for safety in coal mining. The uprights, as key load-bearing components, directly affect the stability of the support. The main components of an upright include the outer cylinder, the middle cylinder, and the piston. Due to varying mining conditions, uprights need to be designed in various specifications. The outer and middle cylinders each weigh hundreds of kilograms to several tons, and the entire upright is even heavier, posing challenges to production and transportation. Upright production involves a series of processes: cleaning, assembly, and testing. The outer cylinder, middle cylinder, and piston must first be cleaned in a cleaning machine, then moved to a cylinder assembling machine for nested assembly. After forming the entire upright, it must be moved to a loading test bench to test its performance. During this process, the movement of the outer cylinder, middle cylinder, piston, and the entire upright between the cleaning machine, cylinder assembling machine, and loading test bench is a necessary link connecting each process and directly affects the production rhythm.

[0003] Currently, the industry generally uses manual crane operation for transportation: the crane is manually controlled, and components are connected and aligned using lifting devices. This method has significant drawbacks: First, the construction cycle is long, the components are heavy and prone to center of gravity shift, requiring repeated trial and error for manual alignment, which is even more time-consuming when switching between multiple specifications; second, the labor intensity is high, requiring operators to continuously monitor and frequently adjust the control levers; third, the safety is poor, as delayed human reaction can easily lead to component shaking, collisions, or even falls; fourth, the production efficiency is low, as only one component is transported at a time, making it difficult to coordinate multiple workstations and limiting production capacity.

[0004] Therefore, there is an urgent need for a hydraulic support transfer system that can replace manually controlled cranes to transfer various types of columns and their main components. Utility Model Content

[0036] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 1 and Figure 2 The orientation is used as a reference.

[0037] Example 1:

[0038] Reference Figures 1 to 6 This embodiment proposes a hydraulic support transfer system for transferring the column and its main components. The main components of the column include an outer cylinder, a middle cylinder, and a piston column. Specifically, the hydraulic support transfer system in this embodiment includes a first frame 1, a second frame 2, a third frame 3, multiple support columns 4, and a hoisting mechanism 5, as detailed below.

[0039] In this embodiment, the hydraulic support transfer system is used to transfer the column and its main components (outer cylinder, middle cylinder, piston column) between workstations such as the cleaning machine, cylinder loading machine, and loading test bench. The three-dimensional transfer action is completed through the coordinated operation of the first frame 1, the second frame 2, the third frame 3, multiple support columns 4, and the hoisting mechanism 5.

[0040] The first frame 1 extends in the front-to-back direction, and its bottom is fixedly connected to the top of multiple support columns 4 by welding, screwing or snapping. The support columns 4 are arranged at intervals along the extension direction of the first frame 1 to form a stable support for the first frame 1 and ensure the stability of the overall structure during transportation.

[0041] The second frame 2 extends in the left and right direction and is mounted on top of the first frame 1. The second frame 2 and the first frame 1 are provided with a matching guide structure, so that the second frame 2 can move smoothly relative to the first frame 1 in the front and back direction. By adjusting the movement in this direction, the position switching of the hoisting mechanism 5 between the front and back work positions can be realized.

[0042] The third frame 3 extends vertically and is assembled inside the second frame 2. A corresponding sliding fit structure is provided between the third frame 3 and the second frame 2. This fit structure can guide the third frame 3 to move horizontally relative to the second frame 2, thereby driving the lower hoisting mechanism 5 to adjust its position horizontally. At the same time, the lower end of the third frame 3 is fixedly connected to the upper part of the hoisting mechanism 5 by welding, screwing, or snapping. The third frame 3 itself has a lifting drive function in the vertical direction, which can drive the hoisting mechanism 5 to move synchronously in the vertical direction to adapt to the height requirements of different work positions.

[0043] The hoisting mechanism 5 is designed to be compatible with the hooking and transportation of columns and their main components. It has a telescopic adjustment function in the left and right directions. The span of the hooking component can be adjusted by telescopic movement, so as to adapt to outer cylinders, middle cylinders, piston columns and integral columns of different lengths, ensuring that all kinds of components can be stably hooked and avoiding falling off or shifting during transportation.

[0044] The transfer process of this transfer system is as follows: When it is necessary to transfer a component (outer cylinder, middle cylinder, piston column) on a certain workstation (such as a cleaning machine), firstly, through the cooperation of the first frame 1 and the second frame 2, the hoisting mechanism 5 is driven to move in the front-to-back direction to the first position where the component is located; then, through the cooperation of the second frame 2 and the third frame 3, the left and right position of the hoisting mechanism 5 is adjusted so that it is aligned with the component to be transferred; next, the third frame 3 drives the hoisting mechanism 5 to descend in the up-down direction. After the hoisting mechanism 5 reaches a suitable height, its left and right extension function is used to adjust the hook span and securely hook the component to be transferred; then, the third frame 3 drives the hoisting mechanism 5 to rise, so that the component is removed from the original support surface. Then, through the coordinated movement of the first frame 1 and the second frame 2, the component is transferred to the second position corresponding to the target workstation (such as a cylinder loading machine); finally, the third frame 3 drives the hoisting mechanism 5 to descend, releasing the hook of the hoisting mechanism 5 on the component, completing a single transfer operation.

[0045] Through the above structural design, the first frame 1, the second frame 2, and the third frame 3 form a three-dimensional driving system, which drives the hoisting mechanism 5 to move flexibly in the front-back, left-right, and up-down directions. There is no need for manual operation of the crane for alignment adjustment. It can adapt to the transportation needs of columns and components of different specifications and achieve efficient connection of various production processes.

[0046] In summary, compared to existing technologies, the first frame 1, the second frame 2, and the third frame 3 can move in the front-back, left-right, and up-down directions, and can coordinate with the retractable hoisting mechanism 5 to achieve the transfer of columns and their components. This replaces manual operation of the crane, significantly reducing labor intensity and avoiding the tedious process of continuous monitoring and frequent adjustments by operators. It is adaptable to components of different specifications, eliminating the need for repeated manual alignment and trial and error, shortening the time spent on switching between multiple specifications and the construction cycle. Simultaneously, it can efficiently connect various production processes across multiple workstations, overcoming the limitations of single-component transfers, effectively improving production efficiency and capacity, and ensuring a stable production rhythm.

[0047] Furthermore, the first frame 1, serving as the basic load-bearing frame of the hydraulic support's transfer system, comprises two guide beams 11 and two cross braces 12. The two guide beams 11 extend parallel to each other in the front-to-back direction, and the two cross braces 12 extend parallel to each other in the left-to-right direction. The ends of the four beams are connected to each other by welding, screwing, or snap-fitting, forming a rectangular frame structure to ensure the overall structural strength and stability of the first frame 1. Each of the two guide beams 11 has a first meshing tooth 111 on its opposite sides, continuously distributed along the extension direction of the guide beams 11, providing a foundation for subsequent transmission and engagement.

[0048] The second frame 2 works in conjunction with the first frame 1 to achieve forward and backward movement. It includes a rectangular frame 21, a first driver 22, and a first gear. The outline of the rectangular frame 21 is adapted to the rectangular frame of the first frame 1 and is mounted between two guide beams 11. The first driver 22 is fixedly mounted on the rectangular frame 21, and its output end is fixedly connected to the first gear through a fixed connection method such as sleeve, welding, or snap-fit, so that the first gear can rotate synchronously with the output end of the first driver 22.

[0049] The first gear engages with the first meshing tooth 111 on the guide beam 11. When the first driver 22 is activated, its output drives the first gear to rotate. Utilizing the inter-tooth transmission between the first gear and the first meshing tooth 111, the rotational power of the first driver 22 is converted into a linear driving force for the rectangular frame 21 along the extension direction of the guide beam 11, thereby driving the entire second frame 2 to move smoothly in the front-back direction. Through this transmission structure, the second frame 2 can achieve precise front-back position adjustment on the first frame 1, providing support for the hoisting mechanism 5 to align with components to be transferred at different front and rear positions.

[0050] Furthermore, the first frame 1 is provided with two first tracks 112 on the side of the first meshing tooth 111 of the guide beam 11. The two first tracks 112 are arranged along the extension direction of the guide beam 11, and are parallel to and corresponding to the first meshing tooth 111, providing a guiding reference for the movement of the second frame 2.

[0051] The rectangular frame 21 of the second frame 2 has two first connecting plates 23 at its bottom. The two first connecting plates 23 are arranged at intervals along the left and right direction of the rectangular frame 21. Their tops are fixedly connected to the bottom of the rectangular frame 21 by welding, screwing, or snapping, forming a stable connection structure. Several sliding trolleys 24 are fixedly mounted on the bottom of each first connecting plate 23. The arrangement direction of the sliding trolleys 24 is consistent with the extension direction of the guide beam 11, and the sliding trolleys 24 form a suitable sliding fit with the first track 112 of the first frame 1. The sliding trolley 24 includes a shell, a bearing sleeve, a rotating shaft, and a drive wheel. The shell is fixed to the bottom of the first connecting plate 23 by welding, screwing, or snapping, while one end of the rotating shaft is rotatably connected to the shell through the bearing sleeve, and the drive wheel is fixed to the other end of the rotating shaft by welding, sleeve, or snapping. Thus, the sliding trolley 24 can slide along the first track 112 of the first frame 1.

[0052] When the second frame 2 moves in the front-to-back direction through the meshing transmission of the first gear and the first meshing tooth 111, the sliding trolley 24 slides synchronously on the first track 112. Through the guiding cooperation between the first track 112 and the sliding trolley 24, the movement trajectory of the second frame 2 is restricted, preventing it from shifting laterally during movement. At the same time, the force deviation between the first gear and the first meshing tooth 111 is reduced, making the front-to-back movement of the second frame 2 more stable and precise, and ensuring the stability of the overall structure during the transfer process.

[0053] Furthermore, the second frame 2 includes two limiting members 25, which are respectively arranged between the two guide rail beams 11 of the first frame 1 and are adapted to the position of the first connecting plate 23 to form lateral limiting protection for the second frame 2.

[0054] Each limiting component 25 includes a limiting rod and a limiting block. The limiting rod extends vertically, and its top end is fixedly connected to the bottom of the first connecting plate 23 by welding, screwing, or snapping, thereby achieving a stable assembly between the limiting component 25 and the second frame 2. The limiting block is fixedly installed at the bottom of the limiting rod by welding, screwing, or snapping. The limiting block has a triangular structure, and its side abuts against the corresponding side of the guide beam 11, forming a surface contact limiting fit.

[0055] When the second frame 2 moves in the front-to-back direction, the limiting block moves synchronously with the first connecting plate 23. Through the side of its triangular structure, it maintains continuous contact with the guide beam 11, effectively limiting the lateral displacement of the second frame 2 and preventing lateral swaying due to inertia or uneven force. Simultaneously, this limiting action further assists in guiding the sliding trolley 24 and the first track 112, reducing meshing deviation between the first gear and the first meshing teeth 111, ensuring precise and stable movement of the second frame 2, and improving the overall operational stability of the transfer system.

[0056] Furthermore, in the rectangular frame 21 of the second frame 2, two sides extending in the left and right directions are arranged opposite each other, and one of the opposite sides of the two sides is provided with a second meshing tooth 211, which is continuously arranged along the extension direction of the side, providing a transmission basis for the left and right movement of the third frame 3.

[0057] The third frame 3 includes a vertical moving component 31, a moving plate 32, a second driver 33, and a second gear. The moving plate 32 has an overall U-shaped structure, and its outline is adapted to the inner outline of the rectangular frame 21, allowing the moving plate 32 to move against the inner wall of the rectangular frame 21. The vertical moving component 31 is fixedly assembled in the internal area of ​​the moving plate 32, achieving a stable connection with the moving plate 32 and moving synchronously with the moving plate 32.

[0058] The second driver 33 is fixedly mounted on the movable plate 32. Its output end is fixedly connected to the second gear by welding, sleeve, or snap-fit, ensuring that the second gear can rotate synchronously with the output end of the second driver 33. The second gear forms a suitable meshing engagement with the second meshing tooth 211 on the side of the rectangular frame 21. When the second driver 33 is started, its output end drives the second gear to rotate. Utilizing the inter-tooth transmission between the second gear and the second meshing tooth 211, the rotational power is converted into a linear driving force for the movable plate 32 along the extension direction of the rectangular frame 21, thereby driving the entire third frame 3 to move smoothly in the left and right directions, achieving precise adjustment of the position of the hoisting mechanism 5 in the left and right directions.

[0059] Furthermore, the hydraulic support transfer system also includes multiple diagonal braces 6, which are distributed in the connection area between each support column 4 and the guide beam 11, forming a reinforced support structure for the first frame 1.

[0060] One end of each diagonal brace 6 is fixedly connected to the side wall of the support column 4 by welding, screwing, or snap-fitting, while the other end is fixedly connected to the bottom of the guide beam 11 by welding, screwing, or snap-fitting. The connection points correspond to the junction between the support column 4 and the guide beam 11, ensuring reasonable force transmission. Through this connection method, the diagonal brace 6, support column 4, and guide beam 11 together form a triangular structure. Utilizing the structural stability characteristics of a triangle, the support strength of the support column 4 on the guide beam 11 is enhanced, effectively dispersing the vertical and horizontal loads borne by the guide beam 11.

[0061] The diagonal brace 6 structure can prevent the first frame 1 from deforming or swaying during the transfer of heavy objects, further improving the overall rigidity and operational stability of the first frame 1, and providing a reliable structural foundation for the smooth movement of the second frame 2.

[0062] Furthermore, in the rectangular frame 21 of the second frame 2, the upper surfaces of the two sides extending in the left and right directions are respectively provided with second tracks 212. The second tracks 212 are arranged along the extension direction of the sides to form a parallel and symmetrical guide structure, providing a stable guide foundation for the movement of the third frame 3.

[0063] The third frame 3 is equipped with at least two second sliders 34. The second sliders 34 are fixedly connected to the bottom of the movable plate 32 by welding, screwing, or snap-fitting, and are evenly distributed along the left and right extension direction of the movable plate 32 to ensure balanced force distribution. The second sliders 34 form a suitable sliding fit with the second track 212 on the upper surface of the rectangular frame 21, and can slide smoothly along the extension direction of the second track 212.

[0064] When the third frame 3 moves in the left and right direction through the meshing transmission of the second gear and the second meshing tooth 211, the second slider 34 slides synchronously on the second track 212. Through the guiding and limiting effect of the second track 212 and the second slider 34, the movement trajectory of the third frame 3 is constrained, preventing it from vertically shifting or laterally deviating during movement. At the same time, the meshing force state of the second gear and the second meshing tooth 211 is optimized, reducing tooth wear and meshing deviation, making the left and right movement of the third frame 3 more stable and precise, and providing a reliable guarantee for the position adjustment of the hoisting mechanism 5.

[0065] Furthermore, the vertical moving assembly 31 includes a housing 314, a third actuator 311, a lead screw 312, a bearing housing 313, and a threaded sleeve. The housing 314 serves as the load-bearing foundation of the vertical moving assembly 31, providing installation support for each component. The bearing housing 313 is fixedly assembled to the bottom end of the housing 314 by welding, screwing, or snap-fit ​​connections. The bottom end of the lead screw 312 is rotatably connected to the bearing housing 313, enabling the lead screw 312 to rotate stably around its own axis. The third actuator 311 is connected to the top end of the lead screw 312 via a coupling, providing a power source for the rotation of the lead screw 312.

[0066] The threaded sleeve and the lead screw 312 form a suitable threaded engagement. At the same time, the threaded sleeve and the lifting mechanism 5 are fixedly connected by welding, screwing, or snap-fitting to achieve synchronous movement of the two. When the third drive 311 is started, its output power drives the lead screw 312 to rotate around its own axis. Utilizing the threaded transmission between the lead screw 312 and the threaded sleeve, the rotational motion of the lead screw 312 is converted into linear motion of the threaded sleeve in the vertical direction. This, in turn, drives the lifting mechanism 5, which is fixedly connected to it, to rise and fall smoothly in the vertical direction, achieving precise position adjustment of the lifting mechanism 5 in the height direction to adapt to the height requirements of different work positions and the lifting and lowering operations of components.

[0067] Furthermore, the lifting mechanism 5 includes a connecting frame 51, a support frame 52, a fourth actuator 53, a reciprocating screw 54, and two lifting components 55. The top end of the connecting frame 51 is fixedly connected to the threaded sleeve by welding, screwing, or snapping, and moves synchronously in the vertical direction with the threaded sleeve. The support frame 52 is fixedly assembled to the bottom end of the connecting frame 51 by welding, screwing, or snapping, forming a bearing base for the fourth actuator 53 and the reciprocating screw 54. The fourth actuator 53 forms a driving connection with the reciprocating screw 54, providing power for the rotation of the reciprocating screw 54. The two lifting components 55 are threadedly engaged with the reciprocating screw 54, and the threads of the two components on the reciprocating screw 54 have opposite directions of rotation.

[0068] When the fourth actuator 53 drives the reciprocating screw 54 to rotate in one direction, the two lifting components 55 move synchronously towards each other along the extension direction of the reciprocating screw 54, reducing the distance between them. When the fourth actuator 53 drives the reciprocating screw 54 to rotate in the opposite direction, the two lifting components 55 move synchronously away from each other along the extension direction of the reciprocating screw 54, increasing the distance between them. Through this bidirectional synchronous movement adjustment, columns and their main components of different lengths can be flexibly adapted, ensuring stable hooking during lifting and meeting the transportation needs under different working conditions.

[0069] Furthermore, the support frame 52 includes a support body 521 and two third rails 522. Each lifting assembly 55 includes a hook 551, a second connecting plate 552, and two third sliders 553. The hook 551 is fixedly assembled above the second connecting plate 552 by welding, screwing, or snapping, etc., to achieve hooking and limiting of the transfer component; the lower part of the second connecting plate 552 is fixedly connected to the two third sliders 553, and the two third sliders 553 are arranged at intervals along the extension direction of the third rails 522 to ensure balanced connection force. The third sliders 553 form a suitable sliding fit with the third rails 522 on the support frame 52, and can slide smoothly along the extension direction of the third rails 522.

[0070] When the fourth actuator 53 drives the reciprocating screw 54 to rotate, causing the two lifting components 55 to move synchronously in both directions, the third slider 553 slides synchronously on the third track 522. Through the guiding and limiting effect of the third track 522 and the third slider 553, the movement trajectory of the lifting components 55 is constrained, preventing lateral deviation or swaying during movement. This ensures that the two lifting components 55 always move smoothly in the preset direction, thereby guaranteeing the precise hooking and stable bearing of the hook 551 on components of different specifications and improving the reliability of the transfer process.

[0072] Reference Figure 8 The difference between this embodiment and embodiment 1 is that this embodiment also includes a clamping assembly that cooperates with the hoisting assembly 55, as detailed below.

[0073] In this embodiment, each lifting assembly 55 is provided with a clamping assembly on its side. The clamping assembly includes a hydraulic rod and a gripper. One end of the hydraulic rod is fixed to the support frame 52 by welding, screwing, or snap-fitting, while the other end is movably connected to the gripper for opening and closing. One end of the gripper is rotatably fixed to the side of the hook 551. The hydraulic rod drives the gripper to rotate, allowing the gripper to form a clamping space with the hook 551 for clamping the column and its main components.

[0074] When the hoisting assembly 55 hooks the column and its main components, the axial and circumferential movement of the column and its main components is prevented by the cooperation between the clamping assembly and the hoisting assembly 55.
