Description

Technical Field

[0001] This utility model relates to the field of precision docking equipment technology, and in particular to a parallel platform anti-tipping support structure for precision docking. Background Technology

[0002] In precision docking operations, parallel platforms often overturn or sway due to external loads, center of gravity shifts, or vibrations, leading to decreased docking accuracy and affecting product quality and equipment safety. Existing support structures are mostly fixed, with the platform itself relying solely on its own structure for support. Under external loads (such as docking impact forces or gravitational eccentricity), it may tilt or shift, causing precision docking failure or even equipment damage.

[0003] The inventors believe that the following defects often exist: the platform body relies solely on its own structure for support, and may tilt or shift under the action of external loads (such as docking impact force, gravitational eccentricity), leading to failure of precision docking or even damage to the equipment; therefore, in order to address the above problems, a parallel platform anti-tipping support structure for precision docking is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the platform body relies solely on its own structure for support, and may tilt or shift under external loads (such as docking impact force or gravitational eccentricity). Therefore, this invention proposes a parallel platform anti-tipping support structure for precision docking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a parallel platform anti-tipping support structure for precision docking, comprising a platform body, a support device provided on the arc surface of the platform body, the support device comprising two adjustment chambers, both adjustment chambers being fixedly connected to the arc surface of the platform body, two support rods being slidably connected inside the adjustment chambers, two fixing rods being fixedly connected to one side of the adjustment chambers, a single-hole plate being slidably connected to the arc surface of the fixing rods, an insert rod being fixedly connected inside the single-hole plate, and several circular holes being opened on the surface of the support rods.

[0006] The aforementioned components achieve the following effect: by setting up a support device, the platform body is supported, avoiding the platform body relying solely on its own structure for support. Under external loads (such as docking impact force or gravitational eccentricity), it may tilt or shift, leading to failure of precision docking or even damage to the equipment, thus improving the practicality of the device.

[0007] Preferably, a spring is fitted onto the arc surface of the fixing rod, and the two ends of the spring are fixedly connected to the single-hole plate and the adjustment chamber, respectively.

[0008] The aforementioned components achieve the following effects: they improve the stability of the insertion rod, and the continuous elastic tension of the spring counteracts external vibrations, impacts, and other interference forces, preventing the insertion rod from loosening or shifting due to external forces. This significantly improves the stability of the connection between the insertion rod and the support rod, ensuring that the entire device maintains reliable support performance during the precision docking process.

[0009] Preferably, a circular plate is fixedly connected to one end of the fixing rod, and the surface of the circular plate is in contact with the single-hole plate.

[0010] The aforementioned components achieve the following effect: they prevent damage to the spring and avoid situations where workers pull the single-hole plate with excessive force, causing the single-hole plate to slide too far on the arc surface of the fixing rod, exceeding the stress range of the spring, resulting in loss of spring elasticity and making it difficult to use normally.

[0011] Preferably, one end of the insertion rod is rotatably connected to a rotating plate, and an operating plate is fixedly connected to the surface of the circular plate.

[0012] The aforementioned components achieve the following effect: they limit the position of the insertion rod, preventing the insertion rod from being affected by external forces when the operator pulls the support rod, thus avoiding displacement of the insertion rod and potential collision with the support rod after displacement, which could cause damage to the insertion rod.

[0013] Preferably, the arc surface of the platform body is provided with a disassembly device, which includes two connecting blocks. Both connecting blocks are fixedly connected to the arc surface of the platform body. A U-shaped frame is slidably connected to the surface of the connecting blocks. A non-circular frame is slidably connected to the surface of the U-shaped frame. The non-circular frame is fixedly connected to the foundation. A sliding rod is slidably inserted inside the non-circular frame. A round rod is fixedly connected to one side of the non-circular frame. A notch plate is rotatably connected to one end of the round rod. A bolt is inserted into the internal thread of the notch plate.

[0014] The aforementioned components achieve the following effect: by setting up a disassembly device, the platform body can be disassembled, avoiding the situation where the platform body needs to be repaired, replaced, or moved to another location. This avoids situations where difficult disassembly operations would require workers to spend a lot of time and energy, or even require the use of destructive tools, which would increase the risk of equipment damage and prolong the downtime maintenance cycle, thus improving the reliability of the device.

[0015] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the irregular frame and the notched plate, respectively.

[0016] The aforementioned components achieve the following effect: they automatically open the notch plate while keeping it in the open position, facilitating further operations by staff.

[0017] Preferably, the arc surface of the bolt is fixedly connected to a blocking plate, and the surface of the blocking plate is in contact with the notch plate.

[0018] The aforementioned components achieve the following effect: preventing bolts from being pulled out, thus avoiding situations where workers turn the bolts too many times, causing the bolt's arc surface to separate from the notch plate, requiring reinstallation for subsequent use and increasing the workload of workers.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting a support device, the effect of supporting the platform body is achieved. It can provide stable multi-point support for the platform body 1 during the precision docking process, significantly improve the platform's anti-overturning ability, and ensure that the docking accuracy is not affected by external forces. It is especially suitable for high-precision scenarios (such as aerospace and precision instrument assembly) where the stability requirements are extremely high.

[0021] 2. In this utility model, by setting a disassembly device, the platform body can be disassembled, and the platform body 1 can be quickly separated or connected to the foundation, which greatly shortens the maintenance, repair and component replacement time and improves equipment availability.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a parallel platform anti-tipping support structure for precision docking, including a platform body 1. The arc surface of the platform body 1 is provided with a support device 2. By setting the support device 2, the platform body 1 is supported, avoiding the platform body 1 from tilting or displacing under external loads (such as docking impact force, gravity eccentricity) due to its own structural bearing, which could lead to precision docking failure or even equipment damage. This improves the practicality of the device. The arc surface of the platform body 1 is provided with a disassembly device 3. By setting the disassembly device 3, the platform body 1 can be disassembled. This avoids the situation where the platform body 1 needs to be repaired, replaced, or moved, and the difficult disassembly operation would require workers to spend a lot of time and energy, or even need to use destructive tools, which would increase the risk of equipment damage and prolong the downtime maintenance cycle. This improves the reliability of the device.

[0030] The specific setup and function of its support device 2 and disassembly device 3 will be explained below.

[0031] Reference Figure 2As shown in the figure, in this embodiment: the support device 2 includes two adjustment chambers 21, both of which are fixedly connected to the arc surface of the platform body 1. Two support rods 22 are slidably connected inside the adjustment chambers 21. Two fixing rods 23 are fixedly connected to one side of each adjustment chamber 21. A single-hole plate 24 is slidably connected to the arc surface of the fixing rods 23. An insert rod 25 is fixedly connected inside the single-hole plate 24. Several circular holes are opened on the surface of the support rods 22. A spring 29 is fitted onto the arc surface of the fixing rods 23. The two ends of the spring 29 are fixedly connected to the single-hole plate 24 and the adjustment chamber 21, respectively. When the operator needs to adjust the length of the support rod 22, the operator first pulls the single-hole plate 24, causing the insert rod 25 to slide on the arc surface of the fixing rod 23, stretching the spring 29 until... The arc surface of the insertion rod 25 separates from the support rod 22. Then, the operator pulls the support rod 22 and slides it within the adjustment chamber 21 until it reaches the appropriate position. Afterward, the operator releases the single-hole plate 24. The rebound force of the spring 29 causes the single-hole plate 24 to slide on the arc surface of the fixed rod 23. The single-hole plate 24 then moves the insertion rod 25 until it is inserted into the circular hole of the support rod 22. This improves the stability of the insertion rod 25. The continuous elastic tension of the spring 29 counteracts external vibrations and impacts, preventing the insertion rod 25 from loosening or shifting due to external forces. This significantly improves the stability of the connection between the insertion rod 25 and the support rod 22, ensuring reliable support performance throughout the precision docking process. One end of the support rod 22 is fixedly connected to a circular plate 26. The surface of the circular plate 26 is in contact with the single-hole plate 24. When the operator needs to adjust the length of the support rod 22, the operator first pulls the single-hole plate 24 to slide it on the arc surface of the fixed rod 23 until the surface of the single-hole plate 24 is in contact with the circular plate 26. At this time, the arc surface of the insertion rod 25 is completely separated from the support rod 22, which achieves the effect of preventing damage to the spring 29. This avoids the situation where the operator pulls the single-hole plate 24 with too much force, causing the single-hole plate 24 to slide too far on the arc surface of the fixed rod 23, exceeding the stress range of the spring 29, causing the spring 29 to lose its elasticity and become difficult to use normally. One end of the insertion rod 25 is rotatably connected to a rotating plate 28. An operating plate 27 is fixedly connected to the surface of the circular plate 26. When the operator needs to adjust the length of the support rod 22, the operator first pulls the single-hole plate 24 and slides it on the arc surface of the fixed rod 23 until the surface of the single-hole plate 24 is in contact with the circular plate 26. Then the operator can rotate the rotating plate 28 at one end of the insertion rod 25 until the surface of the rotating plate 28 is in contact with the operating plate 27. The operator can then pull the support rod 22 normally. At this time, the position of the insertion rod 25 is restricted, which prevents the insertion rod 25 from being affected by external force when the operator pulls the support rod 22, causing the insertion rod 25 to be displaced to a certain extent. After the insertion rod 25 is displaced, it may collide with the support rod 22, causing damage to the insertion rod 25.

[0032] Reference Figure 4 , Figure 5 and Figure 6 As shown, specifically, the disassembly device 3 includes two connecting blocks 31, both of which are fixedly connected to the arc surface of the platform body 1. A U-shaped frame 33 is slidably connected to the surface of the connecting block 31, and a non-circular frame 32 is slidably connected to the surface of the U-shaped frame 33. The non-circular frame 32 is fixedly connected to the foundation, and a sliding rod 34 is slidably inserted inside the non-circular frame 32. A round rod 35 is fixedly connected to one side of the non-circular frame 32, and a notch plate 36 is rotatably connected to one end of the round rod 35. A bolt 37 is inserted into the internal thread of the notch plate 36. The arc of the round rod 35... The surface is fitted with a torsion spring 39, the two ends of which are fixedly connected to the irregular frame 32 and the notch plate 36, respectively. When the worker needs to disassemble the platform body 1, the worker first rotates the bolt 37 inside the irregular frame 32 until the arc surface of the bolt 37 separates from the irregular frame 32. Then, the torque of the torsion spring 39 drives the notch plate 36 to slide inside the slide rod 34 until the notch plate 36 separates from the slide rod 34. Then, the worker pulls the slide rod 34 to slide inside the irregular frame 32 until the arc surface of the slide rod 34 separates from the U-shaped frame 33. When the platform body 1 is disassembled, the operator can push the U-shaped frame 33 to slide within the irregular frame 32 until the U-shaped frame 33 separates from the connecting block 31. Then, the operator can pull the platform body 1 to slide on the foundation surface. This achieves the effect of automatically opening the notch plate 36, while keeping the notch plate 36 in the open state for easy operation. The arc surface of the bolt 37 is fixedly connected to the blocking plate 38, and the surface of the blocking plate 38 is in contact with the notch plate 36. When the operator needs to disassemble the platform body 1, the operator first rotates the bolt 37 within the notch plate 36. The bolt 37 drives the blocking plate 38 to move until the surface of the blocking plate 38 is in contact with the notch plate 36. At this point, the arc surface of the bolt 37 is completely separated from the irregular frame 32, thus preventing the bolt 37 from being pulled off. This avoids the situation where the operator rotates the bolt 37 too many times, causing the arc surface of the bolt 37 to separate from the notch plate 36, requiring reinstallation for the next use and increasing the operator's workload.

[0033] Working principle: When the operator needs to adjust the length of the support rod 22, firstly, the operator pulls the single-hole plate 24, causing the insertion rod 25 to slide on the arc surface of the fixed rod 23. The spring 29 is stretched until the arc surface of the insertion rod 25 separates from the support rod 22. Then, the operator pulls the support rod 22 to slide within the adjustment chamber 21 until the support rod 22 moves to the appropriate position. The operator then releases the single-hole plate 24. At this time, the rebound force of the spring 29 causes the single-hole plate 24 to slide on the arc surface of the fixed rod 23. The single-hole plate 24 moves the insertion rod 25 until it inserts into the circular hole of the support rod 22. When the operator needs to adjust the length of the support rod 22, firstly, the operator pulls the single-hole plate 24 to slide on the arc surface of the fixed rod 23 until the surface of the single-hole plate 24... When the rod 25 is in contact with the circular plate 26, the arc surface of the insertion rod 25 is completely separated from the support rod 22. When the operator needs to adjust the length of the support rod 22, the operator first pulls the single-hole plate 24 to slide on the arc surface of the fixed rod 23 until the surface of the single-hole plate 24 is in contact with the circular plate 26. Then the operator can rotate the rotating plate 28 at one end of the insertion rod 25 until the surface of the rotating plate 28 is in contact with the operating plate 27. The operator can then pull the support rod 22 normally, which achieves the effect of supporting the platform body 1. This avoids the platform body 1 relying solely on its own structure for support, which may tilt or shift under external loads (such as docking impact force or gravity eccentricity), leading to failure of precision docking or even damage to the equipment. This improves the practicality of the device.

[0034] When workers need to disassemble platform body 1, they first rotate bolt 37 within the irregular frame 32 until the arc surface of bolt 37 separates from the irregular frame 32. Then, the torque of torsion spring 39 causes notch plate 36 to slide within slide rod 34 until notch plate 36 separates from slide rod 34. Next, workers pull slide rod 34 within the irregular frame 32 until the arc surface of slide rod 34 separates from U-shaped frame 33. Workers can then push U-shaped frame 33 within the irregular frame 32 until U-shaped frame 33 separates from connecting block 31. Finally, workers can pull platform body 1 to slide on the foundation surface. When workers need to disassemble the platform body 1, they first rotate bolt 37 within the notch plate 36. Bolt 37 moves the baffle plate 38 until the surface of the baffle plate 38 is in contact with the notch plate 36. At this point, the arc surface of bolt 37 is completely separated from the irregular frame 32, achieving the effect of disassembling the platform body 1. This avoids situations where the platform body 1 needs to be repaired, parts replaced, or the site moved, and the difficult disassembly operation would require workers to spend a lot of time and effort, or even require the use of destructive tools, increasing the risk of equipment damage and extending the downtime maintenance cycle. This improves the reliability of the device.
