Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing, specifically to a stepping stone. Background Technology

[0002] In the semiconductor manufacturing process, the maintenance of semiconductor process equipment is indispensable. Among these semiconductor process equipment, some machines are designed to be relatively high, requiring maintenance to be performed at higher positions. These higher positions are normally difficult for maintenance personnel to reach, thus creating difficulties for the maintenance work.

[0003] Currently, to facilitate operations at higher positions on the machine, elevated platforms are used during maintenance. In use, the elevated platform is placed next to the machine, and maintenance personnel climb up the ladder bars to the platform to perform maintenance work, thus reducing the difficulty of the operation.

[0004] In practical use, some machines protrude forward, forming a stepped structure with the ground. To easily avoid these steps, elevated platforms are designed with long and short legs; the long legs support the ground, while the short legs support the stepped structure. However, existing elevated platforms typically only have rollers on the long legs, not the short legs. This makes moving the elevated platform on stepped structures very inconvenient and may even damage the machine. Utility Model Content

[0005] The present invention aims to at least solve the problem that the existing technology of climbing platforms is very inconvenient to move on the stepped structure and may also cause damage to the machine, and proposes a climbing platform.

[0010] In some embodiments, the climbing platform further includes an auxiliary support portion movably connected to the platform body, the auxiliary support portion having a supported state and a retracted state; in the supported state, the auxiliary support portion is used to abut against the first support surface on one side of the platform body to limit the tilt of the platform body, and the auxiliary support portion switches between the supported state and the retracted state by means of movement.

[0011] In some embodiments, the platform body has a first side and a second side in a first horizontal direction, and the first side of the platform body is provided with a climbing structure; the auxiliary support is connected to the first side of the platform body, and in the supported state, the auxiliary support is used to abut against the first support surface corresponding to the first side of the platform body to limit the platform body from tilting to its own first side.

[0012] In some embodiments, the fixed support leg is located on the first side of the platform body, and the folding support leg is located on the second side of the platform body.

[0013] In some embodiments, the auxiliary support includes: a sliding seat slidably connected to the bracket in a vertical direction, the sliding seat being able to slide up or down; and an auxiliary support rod connected to the sliding seat, the sliding seat being used to move the auxiliary support rod away from or closer to the first support surface by raising or lowering it, the auxiliary support rod being used to abut against the first support surface when close to the first support surface, so as to limit the platform body from tilting to its first side.

[0014] In some embodiments, a first end of the auxiliary support rod is rotatably connected to the sliding seat, and a second end of the auxiliary support rod is used to abut against the first support surface in the supported state.

[0019] In some embodiments, the bracket is provided with a vertical groove, and the sliding seat has a movable limiting member located in the groove to guide the sliding seat to move along the groove. The sliding seat can be fixed or slid relative to the bracket by adjusting the limiting member to make the limiting member engage with or slide with the groove.

[0020] In some embodiments, an inner edge is provided at the groove opening of the slide. The sliding seat includes: a slider disposed outside the slide and connected to the auxiliary support rod; an adjusting rod movably connected to the slider; and a limiting member connected to the adjusting rod, which is movably connected to the slider via the adjusting rod, forming a clamping space between the limiting member and the slider, with the inner edge located within the clamping space.

[0021] This utility model's climbing platform, by incorporating an auxiliary moving mechanism, allows the platform to move on the second support surface of the stepped structure, facilitating position adjustment.

[0045] To enable those skilled in the art to better understand the technical solution of this utility model, the climbing platform provided by this utility model will be described in detail below with reference to the accompanying drawings.

[0046] In the semiconductor manufacturing process, the maintenance of semiconductor process equipment is indispensable. Among these semiconductor process equipment, some machines are relatively high, requiring maintenance to be performed at these higher positions, which are normally difficult for maintenance personnel to reach, thus creating difficulties for the maintenance work.

[0047] Currently, to facilitate operations at higher positions on the machine, elevated platforms are used during maintenance. In use, the elevated platform is placed next to the machine, and maintenance personnel climb up the ladder bars to the platform to perform maintenance work, thus reducing the difficulty of the operation.

[0048] like Figure 1 As shown, the elevated platform in the related technology includes: a platform body 1 and a guardrail 2. The guardrail 2 is located on the top of the platform body 1. A climbing structure 3 is provided on the first side of the platform body 1 in the horizontal direction. During maintenance, maintenance personnel move the elevated platform to the front of the machine 4, climb up the elevated platform from the ground using the climbing structure 3, and perform maintenance on the machine 4. After the maintenance of the machine 4 is completed, the maintenance personnel climb down the elevated platform using the climbing structure and move the elevated platform to the next machine 4 location to perform maintenance on the next piece of equipment.

[0049] However, as Figure 1As shown, the machine platform 4 protrudes forward to form a step structure 6 between itself and the ground. The long support leg 7 of the platform rests on the ground, while the short support leg 8 rests on the step structure 6 for maintenance of the machine platform 4. Figure 2 As shown, when maintaining machine 4, there may be multiple machine 4 side by side. In this case, the platform body 1 needs to move on the step structure 6. However, in the prior art, the climbing platform usually only has rollers 5 on the long support leg 7, and in order to ensure stability, there are no rollers 5 on the short support leg 8. This makes it very inconvenient to move the platform body 1, and may also cause damage to the machine 4.

[0050] In addition, the existing climbing platform has a relatively simple support structure for easy movement, and rollers 5 are installed at the bottom of the platform body 1. Although the rollers 5 can be locked during maintenance, the platform body 1 is relatively high and the human body is relatively heavy. When maintenance personnel climb up and down the platform by climbing structure 3, the pulling force generated by the maintenance personnel's hands will cause the overall center of gravity of the climbing platform to shift. If not careful, the climbing platform will overturn, creating a safety hazard.

[0051] To solve the above problems, such as Figure 3 As shown, an embodiment of this utility model discloses a climbing platform for maintaining semiconductor process equipment. The climbing platform includes a platform body 10 and a climbing structure 40.

[0052] like Figures 3 to 5 As shown, the top of the platform body 10 is used for climbing, i.e., standing, and the bottom is used for support on the support surface 100. The platform body 10 has a first side and a second side opposite each other in a first horizontal direction, and a third side and a fourth side opposite each other in a second horizontal direction perpendicular to the first horizontal direction. The first side of the platform body 10 is the side for maintenance personnel to climb up and down. The climbing structure 40 is installed on the first side of the platform body 10, allowing maintenance personnel to climb up or down the platform body 10. The second side of the platform body 10 is the side facing the machine 200, facilitating maintenance personnel to perform maintenance on the machine 200.

[0053] It should be noted that the support surface 100 includes a first support surface 110 and a second support surface 120. The horizontal height of the second support surface 120 is greater than that of the first support surface 110. The platform body 10 can be supported only on the first support surface 110 or simultaneously on the first support surface 110 and the second support surface 120.

[0054] When used in conjunction with the climbing platform, the platform body 10 can be supported at the same horizontal height, for example, Figure 3 As shown, it is directly supported on the ground. However, as Figure 4and Figure 5 Some process modules of the machine tool 200 shown extend forward from the bottom and protrude above the ground, forming a stepped structure 210. In this case, the ground and the top of the stepped structure 210 form two support surfaces 100 with different horizontal heights, that is, the ground forms the first support surface 110, and the top surface of the stepped structure 210 forms the second support surface 120. The platform body 10 in this embodiment can also be supported on both the ground and the stepped structure 210 at the same time.

[0055] like Figure 3 As shown, the platform body 10 includes: a support 11, fixed legs 12, an auxiliary moving mechanism 13, and folding legs 14. The top of the support 11 is used for climbing; the fixed legs 12 are connected to the bottom of the support 11 and are used for support on the first support surface 110; the folding legs 14 are movably connected to the support 11, and the folding legs 14 can be unfolded or folded. The folding legs 14 are used to support the first support surface 110 together with the fixed legs 12 when unfolded, or as... Figure 5 As shown, the folding leg 14 is used to detach from the first support surface 110 and avoid the second support surface 120 which is higher than the first support surface 110 by folding; the auxiliary moving mechanism 13 is movably connected to the bottom of the bracket 11. The auxiliary moving mechanism 13 can be extended or retracted. In the folded state of the folding leg 14, the auxiliary moving mechanism 13 is used to extend and abut against the second support surface 120 so that the bracket 11 can move relative to the second support surface 120, or the auxiliary moving mechanism 13 is used to retract so that the bracket 11 abuts against the second support surface 120.

[0056] like Figure 4 and Figure 5 As shown, during maintenance, multiple process modules in machine tool 200 may be arranged side-by-side. Each process module has a stepped structure 210 extending forward from its bottom. During maintenance, the folding legs 14 need to be folded first, so that the folding legs 14 are disengaged from the first support surface 110 and avoid the stepped structure 210. This allows the bottom of the support 11 to move above the stepped structure 210 and be supported on the second support surface 120 for maintenance of one of the process modules in machine tool 200. When the maintenance of this process module is completed and it needs to be moved to an adjacent process module, the support 11 needs to be moved from the stepped structure 210 of the just-maintained process module to the adjacent stepped structure 210. At this time, the movement of the support 11 can be achieved by extending the auxiliary moving mechanism 13 and abutting against the second support surface 120. After the support 11 moves to the adjacent stepped structure 210, the auxiliary moving mechanism 13 can be retracted, so that the bottom of the support 11 abuts against and is supported on the adjacent second support surface 120 to complete the movement.

[0057] The climbing platform of this utility model, by setting an auxiliary moving mechanism 13, allows the climbing platform to move on the second support surface 120 of the step structure 210, thereby facilitating the adjustment of the climbing platform's position. Since the auxiliary moving mechanism 13 lifts the support 11 when it is in the lowered state, it also avoids friction between the machine platform 200 and the support 11 during movement, preventing damage to the machine platform 200.

[0058] Specifically, such as Figure 6 and Figure 7 As shown, the auxiliary moving mechanism 13 includes: a mounting base 131, a movable plate 132, an auxiliary wheel 133, and a driving member 134. The mounting base 131 is fixedly mounted on the bracket 11; the movable plate 132 is connected to the mounting base 131; the auxiliary wheel 133 is fixedly connected to the movable plate 132 and is used to abut against the second support surface 120; the driving member 134 is rotatably connected to the mounting base 131, and the driving member 134 forms a self-locking or unlocking relationship with the movable plate 132 by rotation; when the auxiliary wheel 133 abuts against the second support surface 120, the driving member 134 abuts against the movable plate 132 and forms a self-locking relationship, and the movable plate 132 lifts the mounting base 131 and the bracket 11 through the driving member 134, so that the bracket 11 disengages from the second support surface 120.

[0059] During maintenance, when the current process module needs to be moved to an adjacent process module after maintenance is completed, the auxiliary wheel 133 will rest on the second support surface 120 of the current step structure 210 under the action of gravity, as shown below. Figure 6 As shown, by operating the drive member 134, the drive member 134 is rotated. The rotating drive member 134 abuts against the movable plate 132, thereby causing the drive member 134 to apply a force to the auxiliary wheel 133 on the second support surface 120 through the movable plate 132. At this time, since the auxiliary wheel 133 is already abutting against the second support surface 120, the auxiliary wheel 133 cannot move. If the drive member 134 continues to rotate, it will cause it to push up the mounting base 131 connected to it and the bracket 11 connected to the mounting base 131 in the opposite direction, causing the entire bracket 11 to rise. Finally, the bottom of the bracket 11 will be separated from the second support surface 120. At the same time, a self-locking mechanism is formed between the drive member 134 and the movable plate 132, fixing the position of the movable plate 132 and the auxiliary wheel 133 and preventing the auxiliary wheel 133 from retracting.

[0060] It should be noted that in this embodiment, one end of the movable plate 132 is rotatably connected to the mounting base 131, but this is not limiting; in other cases, it can be further modified as needed. Figure 7In another embodiment shown, a guide post is provided on the mounting base 131, and both ends of the movable plate 132 can be fitted onto the guide post, rising and falling under the guidance of the guide post, which can also achieve the purpose of assisted movement. That is to say, as long as the auxiliary movement mechanism 13 is movably connected to the mounting base 131, the above situations are all within the protection scope of this utility model without violating the inventive principle and concept of this utility model.

[0061] It is understood that in this embodiment, the driving member 134 is a cam. In order to facilitate the operation of the cam rotation, the auxiliary moving mechanism 13 further includes an operating lever 135. The operating lever 135 is connected to the driving member 134. The driving member 134 can be rotated by the operating lever 135 so that it can form a self-lock or release the self-lock with the movable plate 132.

[0062] like Figure 3 and Figure 5 As shown, the climbing platform also includes two stop blocks 50, both of which are fixedly connected to the bottom of the support 11. One stop block is located on the third side of the platform body 10, and the other is located on the fourth side of the platform body 10. The stop blocks 50 are used for limiting the engagement with the step structure 210 of the machine platform 200. Figure 5 As shown, when the climbing platform needs to be supported on the second support surface 120 of the step structure 210, the folding legs 14 are first folded, and then the platform body 10 is pushed towards the machine platform 200 along the first horizontal direction until the stop block 50 contacts and limits the movement of the step structure 210, preventing the support 11 of the platform body 10 from moving closer to the machine platform 200. At this point, most of the platform body 10 has moved above the step structure 210, while the second side of the platform body 10 has not yet abutted against the side wall of the machine platform 200. It can be seen that by setting the stop block 50, when the support 11 of the platform body 10 moves onto the step structure 210, the second side of the platform body 10 can be prevented from abutting against the side wall of the machine platform 200, thus avoiding collision between the second side of the platform body 10 and the side wall of the machine platform 200.

[0063] like Figure 5 As shown, the support frame 11 includes: a first column 114, a second column 115, a top beam 116, a middle beam 117, and a bottom beam 118. The first column 114 is located on the first side of the platform body 10. There are two first columns 114, spaced apart along a second horizontal direction. Multiple footboards 41 are connected between the two first columns 114, spaced apart from top to bottom, forming a climbing structure 40.

[0064] The second uprights 115 are located on the second side of the platform body 10. There are two second uprights 115, spaced apart along the second horizontal direction. The top beams 116 are located on the top of the platform body 10. There are four top beams 116 connected end-to-end to form a frame structure. The tops of the first uprights 114 and the second uprights 115 are respectively connected and fixed to the frame structure. Support plates 16 for climbing are provided on the frame structure formed by the top beams 116. There are at least two bottom beams 118, located on the third and fourth sides of the platform body 10, respectively. The two ends of the bottom beams 118 are respectively fixedly connected to the bottoms of the corresponding first uprights 114 and second uprights 115 on the same side. The middle beams 117 are located between the top beams 116 and the bottom beams 118. There are also at least two middle beams 117, located on the third and fourth sides of the platform body 10, respectively. The two middle beams 117 are respectively connected between the corresponding first uprights 114 and second uprights 115 on the same side.

[0065] like Figure 3 and Figure 5 As shown, in some embodiments, the stop block 50 is connected to the bottom beam 118, and in the vertical direction, the stop block 50 is located below the bottom beam 118 so that the stop block 50 contacts and limits the engagement with the step structure 210, preventing the second side of the step body 10 from abutting against the side wall of the machine platform 200 when the step body 10 moves onto the step structure 210, thereby avoiding the collision between the second side of the step body 10 and the side wall of the machine platform 200.

[0066] like Figure 3 and Figure 5 As shown, the bottom of the bracket 11 has a support portion 113 for supporting on the second support surface 120. In this embodiment, there are two support portions 113, which are respectively disposed at the bottom of the second column 115.

[0067] Two fixed support legs 12 are connected to the bottom of the first column 114 respectively to support the first support surface 110. Each fixed support leg 12 includes a first support column 121 and a first caster 122. The top of the first support column 121 is connected to the first support column 122, and the bottom of the first support column 121 is connected to the first caster 122. The limiting rod 23 of the auxiliary support part 20 is hinged to the first support column 121. To reduce the assembly process and improve the reliability of the connection, in this embodiment, the first column 114 and the first support column 121 are integrally formed.

[0068] The bracket 11 also includes a main crossbeam 119, which is arranged along the second horizontal direction. The two ends of the main crossbeam 119 rest on the two bottom beams 118 located on the third and fourth sides of the platform body 10, respectively, and the two ends of the main crossbeam 119 extend to the outside of the two bottom beams 118. The main crossbeam 119 is also attached to the second column 115 and is fixedly connected to the bottom beams 118 and the second column 115.

[0069] The folding support 14 is movably connected to the main crossbeam 119. The folding support 14 is movably connected as follows: Figure 3 As shown in the diagram or as... Figure 5 The fold shown is correct.

[0070] In some embodiments, there are two auxiliary moving mechanisms 13, and the mounting bases 131 of the two auxiliary moving mechanisms 13 are respectively connected to the bottom beams 118 at the bottom of the support 11. However, this is not limiting. In some other embodiments not shown in the figures, there can be only one auxiliary moving mechanism 13, which can also be located in the middle of the main crossbeam 119. In other embodiments not shown in the figures, an auxiliary support beam parallel to the main crossbeam 119 can be provided between the two bottom beams 118, and the auxiliary moving mechanism 13 is mounted on the auxiliary support beam. That is to say, as long as the auxiliary moving mechanism 13 is located at the bottom of the support 11, the above situations are all within the protection scope of this utility model without departing from the inventive principle and concept of this utility model.

[0071] Please see Figure 3 When the folding support leg 14 is unfolded, it works together with the fixed support leg 12 to support the ground on the first support surface 110, that is, to support the ground at the same height. Please refer to [link / reference]. Figure 5 When the folding leg 14 is folded, it folds above the second support surface 120, which is above the step structure 210, creating a space between the bottom of the bracket 11 and the ground to accommodate the step structure 210. This allows the bracket 11 to move above the step structure 210, and the support part 113 to rest on the second support surface 120 of the step structure 210. When the bracket 11 is lifted, the support part 113 disengages from the second support surface 120, allowing the bracket 11 to move via the auxiliary wheel 133.

[0072] like Figure 3 and Figure 5 As shown, the platform body 10 also includes: an elastic telescopic rod 15, the two ends of which are rotatably connected to the bracket 11 and the folding leg 14 respectively. The elastic telescopic rod 15 is used to restrict the folding leg 14 to either an unfolded or folded state.

[0073] The step platform of this utility model, by setting an elastic telescopic rod 15, can keep the folding support leg 14 in the folded or open position. When the elastic telescopic rod 15 keeps the folding support leg 14 in the folded position, it can facilitate the movement of the platform body 10 and prevent the folding support leg 14 from bumping into the machine 200 equipment. When the elastic telescopic rod 15 keeps the folding support leg 14 in the open position, it can improve the stability of the folding support leg 14 and ensure the safety of maintenance personnel.

[0074] Specifically, the folding support leg 14 includes a swinging part 141 and a second support column 142. The swinging part 141 is swayably connected to the bracket 11, and the elastic telescopic rod 15 is connected to the swinging part 141; the first end of the second support column 142 is fixedly connected to the swinging part 141, and the second end of the second support column 142 is used to support the first support surface 110. The swinging part 141 swings to move the second end of the second support column 142 closer to or away from the first support surface 110.

[0075] like Figure 3 As shown, in some embodiments, the folding leg 14 further includes a second caster 143, which is connected to the second support column 142.

[0076] For example, such as Figure 3 and Figure 5 As shown, the swing part 141 is swayably connected to the main crossbeam 119 on the bracket 11. The swing axis of the swing part 141 extends along the second horizontal direction. The first end of the second support column 142 is fixedly connected to the swing part 141. The second end of the second support column 142 is connected to the second caster 143 so as to support on the first support surface 110. The swing part 141 drives the second support column 142 to swing synchronously by swinging, so that the second end of the second support column 142 moves closer to or away from the first support surface 110, thereby causing the second caster 143 to support on or detach from the first support surface 110. The elastic telescopic rod 15 is connected to the swing part 141.

[0077] like Figure 8 As shown, the swing part 141 includes a first connecting rod 141a and a second connecting rod 141b. There are two second connecting rods 141b, two second support columns 142, and two second casters 143. The two second connecting rods 141b are respectively connected to the two ends of the first connecting rod 141a, each second connecting rod 141b is connected to a second support column 142, and each second support column 142 is connected to a second caster 143.

[0078] Among them, such as Figure 5 As shown, the first connecting rod 141a is arranged parallel to the main crossbeam 119, and the first connecting rod 141a is hinged to the main crossbeam 119 so that it can swing relative to the main crossbeam 119. Figure 5 As shown, when the folding support leg 14 is folded, the first connecting rod 141a is close to the main crossbeam 119 in the first horizontal direction, while in the vertical direction, the first connecting rod 141a is located above the bottom beam 118 and a certain distance away from the bottom beam 118; as Figure 9As shown, when the folding leg 14 is unfolded, the first connecting rod 141a moves away from the main crossbeam 119 in the first horizontal direction, while in the vertical direction, the first connecting rod 141a moves to a position above and close to the bottom beam 118. The first connecting rod 141a moves between the two positions by swinging.

[0079] like Figure 8 As shown, the second connecting rod 141b has a first end and a second end. The first end of the second connecting rod 141b is fixedly connected to the first end of the second support column 142, and the second connecting rod 141b and the second support column 142 are perpendicular to each other to form an L-shaped structure. The end of the first connecting rod 141a is fixedly connected to the middle of the second connecting rod 141b, and is perpendicular to both the second connecting rod 141b and the second support column 142.

[0080] like Figure 5 As shown, when the folding support leg 14 is folded, that is, when the first connecting rod 141a swings to a position close to the main crossbeam 119 and away from the bottom beam 118, the second connecting rod 141b is in a vertical state, and the second support column 142 is in a horizontal state extending along the first horizontal direction. At this time, the height of the second support column 142 is higher than the height of the second support surface 120, so as to avoid the step structure 210 and move the bracket 11 above the step structure 210.

[0081] like Figure 3 and Figure 9 As shown, when the folding support leg 14 is unfolded, that is, when the first connecting rod 141a swings to a position away from the main crossbeam 119 and close to the bottom beam 118, the second connecting rod 141b is in a horizontal state extending along the first horizontal direction, the second support column 142 is in a vertical state, and the first end of the second support column 142 abuts against the main crossbeam 119. The second support column 142 provides support to the entire bracket 11 through the main crossbeam 119.

[0082] In this embodiment, there are two elastic telescopic rods 15, which are located on the third and fourth sides of the platform body 10, respectively. The first end of the elastic telescopic rod 15 is rotatably connected to the middle beam 117 and located near the first column 114. The second end of the elastic telescopic rod 15 is rotatably connected to the second end of the second connecting rod 141b.

[0083] Please see Figure 3 or Figure 9When the folding support leg 14 is unfolded, that is, when the second connecting rod 141b is in a horizontal state extending along the first horizontal direction and the second support column 142 is in a vertical state and abuts against the main crossbeam 119, the elastic telescopic rod 15 extends under the action of elastic force and abuts against the second end of the second connecting rod 141b, applying a pushing force to the second connecting rod 141b, causing the second end of the second connecting rod 141b to tend to rotate closer to the first support surface 110. Since the connection position of the first connecting rod 141a is located in the middle of the second connecting rod 141b, and the swing axis of the second connecting rod 141b is also located near the middle of the second connecting rod 141b, the second connecting rod 141b forms a lever-like structure. When the second end of the second connecting rod 141b tends to rotate towards the first support surface 110, the first end of the second connecting rod 141b tends to rotate towards the main crossbeam 119. The second end of the second connecting rod 141b is connected to the second support column 142, which is already abutting against the main crossbeam 119. In other words, under the action of thrust, the second support column 142 can remain abutting against the main crossbeam 119, thus keeping the folding leg 14 in the unfolded state.

[0084] During the unfolding or folding process of the folding support leg 14, the first connecting rod 141a drives the second connecting rod 141b to swing synchronously. When the second connecting rod 141b swings, the movement trajectory of its second end is an arc-shaped trajectory around the swing axis. Therefore, the second end of the elastic telescopic rod 15, which is second connected to the second connecting rod 141b, is also an arc-shaped trajectory. It is easy to see that when the folding support leg 14 is unfolded, the elastic telescopic rod 15 first extends and abuts against the second connecting rod 141b. During the process driven by the second connecting rod 141b, the elastic telescopic rod 15 gradually shortens. When the second end of the elastic telescopic rod 15 passes the apex of the arc-shaped trajectory, the elastic telescopic rod 15 gradually extends.

[0085] Please see Figure 5 When the folding leg 14 is folded, that is, the second connecting rod 141b is in a vertical state and the second support column 142 is in a horizontal state, the elastic telescopic rod 15 extends again and continues to press against the second connecting rod 141b to apply a pushing force to the second connecting rod 141b. Under the action of the pushing force, the second connecting rod 141b will drive the first connecting rod 141a to move closer to the main crossbeam 119. At this time, the first connecting rod 141a is already in a position close to the main crossbeam 119. Under the action of the pushing force, the first connecting rod 141a presses against the main crossbeam 119, keeping the first connecting rod 141a in a position close to the main crossbeam 119. Therefore, the second support column 142 can overcome the effect of gravity and always be at a horizontal height higher than the second support surface 120, thereby keeping the folding leg 14 in a folded state, improving the stability of the folding leg 14, and ensuring the safety of maintenance personnel.

[0086] In some embodiments, the auxiliary support 20 is movably connected to the treadmill body 10. The auxiliary support 20 has a supported state and a retracted state. In the supported state, the auxiliary support 20 is used to abut against a first support surface 110 on one side of the treadmill body 10 to limit the tilt of the treadmill body 10. The auxiliary support 20 can switch between the supported state and the retracted state by means of movement.

[0087] The climbing platform of this utility model has a movable auxiliary support part 20, which can be abutted against the support surface 100 on one side of the platform body 10 to provide auxiliary support and effectively prevent the climbing platform from tipping over, thereby ensuring the safety of the maintenance process.

[0088] like Figure 3 As shown, the auxiliary support 20 is located on the first side of the platform body 10, that is, on the same side as the climbing structure 40. In the supported state, the auxiliary support 20 is used to abut against the first support surface 110 corresponding to the first side of the support 11 to limit the support 11 from tilting towards its own first side.

[0089] like Figure 3 As shown, during the process of maintenance personnel ascending and descending the platform 10, by switching the movable auxiliary support 20 to the support state, the auxiliary support 20 abuts against the support surface 100 corresponding to the first side of the platform 10. Even if the center of gravity of the platform 10 shifts due to the maintenance personnel climbing the platform 10, the auxiliary support 20 can provide support force to prevent the platform 10 from tilting to its first side, thereby effectively ensuring the stability of the platform 10. When moving the platform after maintenance or when the platform is idle, such as... Figure 4 As shown, the auxiliary support 20 can be switched to a retracted state, which facilitates the movement of the platform body 10 and reduces the floor space occupied.

[0090] The climbing platform of this utility model has a movable auxiliary support part 20. The auxiliary support part 20 can be abutted against the support surface 100 on the first side of the platform body 10, thereby providing auxiliary support on the first side of the platform body 10. This effectively limits the platform body 10 from tilting to its first side due to center offset, thereby improving the stability and reliability of maintenance personnel when going up and down the platform body 10 and ensuring the safety of the maintenance process. At the same time, when moving the platform body 10 after maintenance, the auxiliary support part 20 can be switched to the retracted state to facilitate the movement of the platform body 10.

[0091] like Figure 3 and Figure 5 As shown, the fixed support leg 12 is located on the first side of the platform body 10, and the folding support leg 14 is located on the second side of the platform body 10. This facilitates maintenance personnel climbing up and down the platform when it is supported on the step structure 210.

[0092] like Figure 3 , Figure 5 and Figure 9 As shown, in order to ensure the stability of the support, in this embodiment, there are two auxiliary support parts 20, and each first column 114 is connected to an auxiliary support part 20.

[0093] In some embodiments, such as Figure 5 As shown, the auxiliary support part 20 includes: a sliding seat 21, an auxiliary support rod 22, and a limiting rod 23. The sliding seat 21 is slidably connected to the bracket 11 of the platform body 10 in a vertical direction, and the sliding seat 21 rises or falls by sliding. The auxiliary support rod 22 is connected to the sliding seat 21. The sliding seat 21 is used to move the auxiliary support rod 22 closer to or away from the first support surface 110 by raising or lowering it. When the auxiliary support rod 22 is close to the first support surface 110, it abuts against the first support surface 110 to limit the platform body 10 from tilting to its first side. In use, the rise or fall of the sliding seat 21 can drive the auxiliary support rod 22 to rise or fall synchronously. The auxiliary support rod 22 moves closer to the first support surface 110 and finally abuts against the first support surface 110 by falling, thus providing auxiliary support for the platform body 10 and preventing the platform body 10 from tilting to its first side. The auxiliary support rod 22 moves away from the first support surface 110 by rising, so that the platform body 10 can move.

[0094] In this embodiment, the first end of the auxiliary support rod 22 is rotatably connected to the sliding seat 21, for example, by a hinge. The second end of the auxiliary support rod 22 is used to abut against the first support surface 110 in a supported state. The auxiliary support rod 22 can rotate to move its second end away from or towards the bracket 11 of the platform body 10 in a first horizontal direction. That is, the auxiliary support rod 22 is swayably connected to the bracket 11. The auxiliary support rod 22 can move away from or towards the bracket 11 in the first horizontal direction by swaying, thereby enabling the auxiliary support rod 22 to support the platform body 10 more stably.

[0095] The first end of the limiting rod 23 is rotatably connected to the auxiliary support rod 22, and the second end of the limiting rod 23 is rotatably connected to the fixed support leg 12. The limiting rod 23 is used to restrict the second end of the auxiliary support rod 22 from moving away from the fixed support leg 12 in the supported state of the auxiliary support part 20.

[0096] For example, the first end of the limiting rod 23 is hinged to the auxiliary support rod 22, and the second end of the limiting rod 23 is hinged to the fixed support leg 12. The limiting rod 23 is used to restrict the second end of the auxiliary support rod 22 from moving away from the platform body 10 when the auxiliary support part 20 is in the supported state. By setting the limiting rod 23, the auxiliary support rod 22, the limiting rod 23, and the fixed support leg 12 of the platform body 10 are connected in a hinged manner to form a triangular structure. The state of the auxiliary support part 20 can be adjusted by changing the angle of the triangular structure. At the same time, when the auxiliary support part 20 is in the supported state, the position of the second end of the auxiliary support rod 22 can also be restricted by the limiting rod 23 to prevent the second end of the auxiliary support rod 22 from moving away from the platform body 10 in the first horizontal direction. This allows the auxiliary support rod 22 to provide a stable supporting force to the platform body 10, preventing the platform body 10 from tipping over when maintenance personnel climb it.

[0097] Specifically, such as Figure 5 , Figure 9 and Figure 10 As shown, in the supported state of the auxiliary support part 20, the sliding seat 21 drives the auxiliary support rod 22 to descend to a position close to the first support surface 110, and the second end of the auxiliary support rod 22 is away from the fixed support leg 12 of the platform body 10 in the first horizontal direction; as Figure 3 As shown, in the retracted state of the auxiliary support part 20, the sliding seat 21 drives the auxiliary support rod 22 to rise to a position where it is separated from the first support surface 110, and the second end of the auxiliary support rod 22 approaches the fixed support leg 12 of the platform body 10 in the first horizontal direction.

[0098] In other words, during use, as the sliding seat 21 lowers the auxiliary support rod 22, the auxiliary support rod 22 also swings, causing its second end to move away from the fixed support leg 12 of the pedal body 10 in the first horizontal direction, until the limiting rod 23 is in a horizontal state. At this point, the second end of the auxiliary support rod 22 is furthest from the fixed support leg 12 of the pedal body 10 in the first horizontal direction, and the auxiliary support part 20 is in a supported state. When it is necessary to retract the auxiliary support part 20, the sliding seat 21 raises the auxiliary support rod 22, and at the same time, the auxiliary support rod 22 swings, causing its second end to move closer to the fixed support leg 12 of the pedal body 10 in the first horizontal direction, until the limiting rod 23 is in a vertical state, and the second end of the auxiliary support rod 22 is at the position closest to the fixed support leg 12 of the pedal body 10, and the auxiliary support part 20 is in a retracted state.

[0099] The climbing platform of this invention, by setting a sliding seat 21, an auxiliary support rod 22, and a limiting rod 23, allows the auxiliary support part 20 to switch between a supported state and a retracted state. On the one hand, it ensures that the auxiliary support part 20 provides auxiliary support to the first side of the platform body 10, effectively limiting the platform body 10 from tilting to its first side due to center offset, thereby improving the stability and reliability of maintenance personnel when climbing up and down the platform body 10 and ensuring the safety of the maintenance process; on the other hand, when moving the platform body 10 after maintenance, the auxiliary support part 20 can be switched to the retracted state, facilitating the movement of the platform body 10, improving operational convenience, and reducing the floor space occupied.

[0100] like Figure 11 As shown, in this embodiment, a sliding groove 111 is provided on the support 11 of the platform body 10 along the vertical direction, and the sliding seat 21 slides in cooperation with the sliding groove 111. Figure 12 As shown, an inner edge 112 is provided at the opening of the slide groove 111. In a horizontal cross-section, it can be seen that the slide groove 111 is a C-shaped groove, and the sliding seat 21 slides along the slide groove 111. That is to say, please refer to... Figure 5 , Figure 6 and Figure 11 The slide groove 111 is provided on the first column 114, and each first column 114 is provided with a slide groove 111 along the vertical direction so that the sliding seat 21 can slide and cooperate with the slide groove 111.

[0101] Specifically, such as Figure 12 As shown, the sliding seat 21 has a movable limiting member 213 located within the slide groove 111, used to guide the sliding seat 21 to move along the slide groove 111. The sliding seat 21 can be fixed or slidably engaged with the sliding groove 111 by adjusting the limiting member 213, thereby fixing or sliding the sliding seat 21 relative to the support 11 of the platform body 10. Adjusting the limiting member 213 allows it to be either in a limiting or sliding engagement with the slide groove 111. When the limiting member 213 is in a sliding engagement with the slide groove 111, it guides the direction of the sliding seat 21. Simultaneously, when the limiting member 213 is in a limiting engagement with the slide groove 111, it fixes the sliding seat 21 to the support 11 of the platform body 10, thus keeping the auxiliary support 20 in a retracted or supported state. When retracted, it facilitates movement of the platform body 10; when supported, the anti-reverse mechanism improves the stability and reliability of the auxiliary support 20.

[0102] like Figure 12 and Figure 13As shown, the sliding seat 21 includes a slider 211, an adjusting rod 212, and a limiting member 213. The slider 211 is disposed outside the slide groove 111 and is hinged to the auxiliary support rod 22. The adjusting rod 212 is movably connected to the slider 211. The limiting member 213 is connected to the adjusting rod 212 and is movably connected to the slider 211 through the adjusting rod 212. A clamping space is formed between the limiting member 213 and the slider 211, and the inner edge 112 is located within the clamping space. The adjusting rod 212 moves to clamp or release the inner edge 112 between the slider 211 and the limiting member 213, so that the sliding seat 21 is fixed or slides relative to the bracket 11.

[0103] For example, such as Figure 12 As shown, the slider 211 is provided with a first through hole, the adjusting rod 212 passes through the first through hole and is rotatable relative to the first through hole. At the same time, the slider 211 and the adjusting rod 212 are in a limiting fit along the axis of the adjusting rod 212, thereby realizing the movable connection between the adjusting rod 212 and the slider 211.

[0104] The limiting member 213 is a limiting block disposed within the slide groove 111. There is a movable gap between the limiting block and the slide groove 111, allowing the limiting block to slide relative to the slide groove 111, but the movable gap is insufficient to allow the limiting block to rotate relative to the slide groove 111. A first threaded hole is provided on the limiting member 213. One end of the adjusting rod 212 is located within the slide groove 111 and threadedly engaged with the limiting member 213. A handle 214 is provided on the other end of the adjusting rod 212 to control its rotation. This allows the limiting member 213 to be movably connected to the slider 211 via the adjusting rod 212. Simultaneously, a clamping space is formed between the limiting member 213 and the slider 211, with the inner edge 112 located within this clamping space.

[0105] When the adjusting rod 212 is rotated via the handle 214, the limiting member 213 is limited by the slide groove 111 and cannot rotate with the adjusting rod 212. This causes the adjusting rod 212 and the limiting member 213 to rotate relative to each other. Under the threaded engagement, the limiting member 213 can move along the axis of the adjusting rod 212. By moving closer to or further away from the slider 211, the limiting member 213 reduces or expands the clamping space, thereby cooperating with the slider 211 to clamp or release the inner edge 112. This allows the sliding seat 21 to be fixed or slide relative to the platform body 10.

[0106] In the supported state of the auxiliary support part 20, to ensure the reliability of the support of the auxiliary support rod 22, the auxiliary support rod 22 and the sliding seat 21 need to be fixed relative to the bracket 11 of the platform body 10. At this time, by rotating the adjusting rod 212, the limiting member 213 and the slider 211 clamp and lock the inner edge 112, thereby keeping the auxiliary support part 20 in the supported state and improving the reliability of the auxiliary support part 20 in the supported state. In the retracted state, the limiting member 213 and the slider 211 can also clamp and lock the inner edge 112, thereby keeping the auxiliary support part 20 in the retracted state for easy movement and storage. In addition, when it is necessary to switch states, the adjusting rod 212 can be rotated in the opposite direction to release the inner edge 112 of the limiting member 213 and the slider 211, and the sliding seat 21 can slide along the slide groove 111 to complete the switch between the supported state and the retracted state.

[0107] like Figure 11 As shown, to ensure the stability of the auxiliary support 20, the climbing platform also includes a reverse stop mechanism 30. The reverse stop mechanism 30 is movably connected to the bracket 11 of the platform body 10. The reverse stop mechanism 30 restricts the sliding seat 21 from rising by engaging or disengaging from the vertical limit engagement with the sliding seat 21. By setting the reverse stop mechanism 30, the rising of the sliding seat 21 can be restricted when the auxiliary support 20 is in the supported state, thereby preventing the auxiliary support rod 22 from accidentally rising and retracting, thus confining the auxiliary support 20 to the supported state, improving the stability of the auxiliary support 20, and ensuring the safety of maintenance personnel during climbing. Furthermore, it can be used in conjunction with the clamping state of the limiting member 213 and the slider 211 to form a double safety measure, improving the reliability of the auxiliary support 20 in the supported state.

[0108] like Figure 14 As shown, specifically, the anti-reverse mechanism 30 includes a connecting seat 31 and a locking tongue 32. The connecting seat 31 is fixedly connected to the bracket 11 of the platform body 10, and is located near the moving path of the sliding seat 21. The locking tongue 32 is rotatably connected to the connecting seat 31. The locking tongue 32 can rotate to enter or leave the moving path of the sliding seat 21, thereby limiting or disengaging from the sliding seat 21. By setting the connecting seat 31 and the locking tongue 32, in the supported state of the auxiliary support 20, the locking tongue 32 can be rotated to enter the moving path of the sliding seat 21, thereby preventing the sliding seat 21 from sliding and preventing it from rising, thus achieving a limit. When it is necessary to retract the auxiliary support 20, the locking tongue 32 can be rotated in the opposite direction to prevent the sliding seat 21 from moving, thereby allowing the sliding seat 21 to rise and switching the auxiliary support 20 to the retracted state.

[0109] In this embodiment, as Figure 14As shown, the connecting seat 31 includes: a mounting block 311, a mounting plate 312, a positioning bolt 314, and a connecting shaft 315. In a first horizontal direction, the mounting block 311 has a first end and a second end. The first end of the mounting block 311 is close to the movement path of the sliding seat 21, and the second end of the mounting block 311 is away from the movement path of the sliding seat 21. In a second horizontal direction perpendicular to the first horizontal direction, the mounting block 311 has a first side and a second side. The first side of the mounting block 311 is fixedly connected to the bracket 11 of the platform body 10 by bolts, and the first side of the mounting block 311 is the side close to the movement path of the sliding seat 21.

[0110] It is understandable that there are also two backstop mechanisms 30, with one backstop mechanism 30 provided on each first column 114. The first side of each mounting block 311 is fixedly connected to the corresponding first column 114, and the orientation of the first end of each mounting block 311 is the same as the orientation of the groove opening of the slide 111.

[0111] Mounting plate 312 is fixedly connected to the second side of mounting block 311. In the first horizontal direction, mounting plate 312 has a first end and a second end. The first end of mounting plate 312 extends out of the first end of mounting block 311 in the first horizontal direction to form an abutment section 313. A positioning bolt 314 is provided on the abutment section 313.

[0112] A connecting shaft 315 is provided on the end face of the first end of the mounting block 311 along the first horizontal direction. The middle part of the locking tongue 32 is rotatably connected to the mounting block 311 through the connecting shaft 315. The locking tongue 32 has a limiting end 321 and an operating end 322. The limiting end 321 of the locking tongue 32 is located on the moving path of the sliding seat 21 so as to limit the engagement with the sliding seat 21. The operating end 322 of the locking tongue 32 abuts against the positioning bolt 314. A return spring 33 is provided between the mounting plate 312 and the locking tongue 32. The two ends of the return spring 33 abut against the mounting plate 312 and the locking tongue 32 respectively. The return spring 33 is used to apply elastic force to the locking tongue 32 so that the limiting end 321 of the locking tongue 32 is always kept in the position of limiting engagement with the sliding seat 21.

[0113] When the sliding seat 21 needs to rise, the operating end 322 of the latch 32 can be pushed away from the mounting plate 312, causing the limiting end 321 of the latch 32 to move closer to the mounting plate 312, disengaging from the movement path of the sliding seat 21, allowing the sliding seat 21 to rise normally. Simultaneously, the return spring 33 is compressed. When the sliding seat 21 needs to be limited, the operating end 322 of the latch 32 can be released, and the return spring 33 pushes the limiting end 321 of the latch 32 onto the movement path of the sliding seat 21, thus achieving a limiting engagement with the sliding seat 21.

[0114] It should be noted that, in this embodiment, the positioning bolt 314 rotates to move the operating end 322 of the locking tongue 32 away from or closer to the mounting plate 312, thereby adjusting the extent to which the limiting end 321 of the locking tongue 32 extends into the moving path of the sliding seat 21, so as to ensure the stability of the limiting engagement with the sliding seat 21.

[0115] To facilitate the locking tongue 32 to limit the sliding seat 21 only during the upward movement of the sliding seat 21, the limiting end 321 of the locking tongue 32 is provided with a limiting end face 321a and a guide face 321b. Among them, the limiting end face 321a is parallel to the support surface 100, that is, perpendicular to the moving direction of the sliding seat 21, and the limiting end face 321a faces the support surface 100, that is, towards the bottom of the platform body 10. When the sliding seat 21 rises, the limiting end face 321a of the locking tongue 32 is located on the moving path of the sliding seat 21 and is perpendicular to the moving path of the sliding seat 21. During the rising process, the sliding seat 21 will abut against the limiting end face 321a. If the sliding seat 21 continues to rise, it can only push the limiting end face 321 of the locking tongue 32 to rotate away from the mounting plate 312, and the operating end face 322 of the locking tongue 32 will approach the mounting plate 312. However, at this time, the operating end face 322 of the locking tongue 32 has already abutted against the positioning bolt 314 and cannot continue to approach the mounting plate 312. Therefore, the limiting end face 321 of the locking tongue 32 cannot move, thereby preventing the sliding seat 21 from continuing to rise.

[0116] The guide surface 321b is inclined. During the descent of the sliding seat 21, after the sliding seat 21 abuts against the guide surface 321b, it will push the limiting end 321 of the locking tongue 32 to move closer to the mounting plate 312, pushing the operating end 322 of the locking tongue 32 away from the moving path of the sliding seat 21, thereby realizing the descent of the sliding seat 21. Since the operating end 322 of the locking tongue 32 moves away from the mounting plate 312 during this process, it will not restrict the movement of the operating end 322 of the locking tongue 32, thereby realizing the one-way limiting of the locking tongue 32.

[0117] like Figure 5 As shown, the climbing platform also includes a guardrail 60, which is installed on top of the support 11 of the platform body 10. The guardrail 60 is fixedly connected to the top beam 116 by bolts. During use by maintenance personnel, the guardrail 60 serves a protective function to prevent falls and acts as a handrail during climbing. A protective door 70 is connected to the guardrail 60. The protective door 70 can only open inwards. After personnel enter the work area, the protective door 70 automatically closes due to spring force to prevent personnel from falling from the entrance side.

[0118] like Figure 15As shown, the safety door 70 is connected to the guardrail 60 via a hinge 71. The hinge 71 has a torsion spring 72, which keeps the door closed. After the user opens the door to enter the work area, the safety door 70 automatically closes under the action of the torsion spring 72. The safety door 70 can only open inwards. After the user enters the work area, the safety door 70 automatically closes, preventing the user from falling from the entrance and thus protecting the user.

[0119] like Figure 11 As shown, a protective plate 80 is also provided at the bottom of the guardrail 60. The protective plate 80 is connected to the guardrail 60 and the top beam 116 of the support 11 of the platform body 10 by bolts, to prevent personnel from sticking their feet out of the work area and kicking the equipment during use.

[0120] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
