[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0040] This utility model relates to a self-driven maintenance platform for channel-shaped steel beam flange plates, used for high-altitude maintenance of steel beam flange plates. This utility model features a simple structure, high safety and reliability, convenient operation, and a high degree of automation, effectively improving construction efficiency and ensuring safety during high-altitude operations. Furthermore, the modular design of each component facilitates disassembly and assembly, allowing for flexible combination and adjustment according to different construction needs, resulting in good economic efficiency. It offers significant advantages over traditional suspended platforms.
[0041] A self-driven maintenance platform with channel-shaped steel beam flanges, such as Figure 1-8 As shown, the system includes a suspended platform and multiple longitudinally spaced I-beams 1 on the flanges of the steel beams, and also includes: at least three independently operating drive systems 15 and longitudinally arranged longitudinal track beams 9 connected to the suspended platform; the drive system 15 includes:
[0042] The lateral movement mechanism can be adjusted and moved laterally along the I-beam 1;
[0043] The longitudinal moving mechanism can be adjusted and moved longitudinally along the longitudinal track beam 9;
[0044] A vertical adjustment mechanism, vertically adjustable, is connected to the horizontal and vertical movement mechanisms.
[0045] In use, this utility model can achieve three-dimensional position and posture adjustment of the suspended platform in the horizontal, vertical and vertical directions by adjusting the lateral moving mechanism to move on the I-beam 1, the longitudinal moving mechanism to move on the longitudinal track beam 9, and the vertical adjusting mechanism to move in the vertical direction.
[0046] like Figure 1 As shown, the horizontal direction is perpendicular to the paper, the vertical direction is left and right, and the vertical direction is up and down.
[0047] In one embodiment, such as Figure 1 , 2As shown in Figure 3, the lateral movement mechanism includes lateral rollers 3 that are placed on both sides of the longitudinal direction of the I-beam 1 and can be laterally rolled on the lower flange plate 102 of the I-beam, and a lateral drive motor 2 for driving the lateral rollers 3 to roll on the lower flange plate 102 of the I-beam.
[0048] The transverse roller 3 is engaged with the top of the lower flange plate 102 of the I-beam, providing a vertical support for the transverse movement mechanism of the I-beam 1 and the structure below it. The transverse movement motor drive system 2 can make the transverse roller 3 roll on the lower flange plate 102 of the I-beam to adjust the transverse position of the drive system 15.
[0049] In one embodiment, such as Figure 1 , 2 As shown in Figures 6 and 7, the transverse movement mechanism also includes a drive opening and closing device 4 for controlling the two sets of transverse rollers 3 on both sides of the longitudinal direction of the I-beam 1 to move longitudinally so as to clamp or release the I-beam 1.
[0050] The start-up drive opening and closing device 4 is set up so that the movement of a single drive system 15 on multiple longitudinally spaced I-beams 1 on the flange plate of the steel beam can be completed by controlling the clamping or loosening of the two transverse rollers 3 with the I-beam. The movement process includes clamping state and loosening state.
[0051] When the two transverse rollers 3 are clamped to the I-beam 1, the two transverse rollers 3 are located between the upper flange plate 101 and the lower flange plate 102 of the I-beam, on both sides of the web plate 103 of the I-beam, and the transverse rollers 3 are in complete contact with the top of the lower flange plate 102 of the I-beam.
[0052] When the two transverse rollers 3 are detached from the I-beam 1, the two transverse rollers 3 are located away from the web 103 of the I-beam and are detached from the top of the lower flange 102 of the I-beam.
[0053] The clamping and releasing process is as follows: the drive opening and closing device 4 is activated, and the two transverse rollers 3 move away from the web plate 103 of the I-beam until they are released from the top of the lower flange plate 102 of the I-beam.
[0054] The process of its release and clamping is as follows: the drive opening and closing device 4 is activated, and the two transverse rollers 3 move towards the web plate 103 of the I-beam until the two transverse rollers 3 are in complete contact with the top of the lower flange plate 102 of the I-beam.
[0055] In one embodiment, such as Figure 1 , 8As shown, the drive opening and closing device 4 includes a transmission rod 402 fixed to the upper end of the vertical adjustment mechanism and arranged longitudinally; sleeves 404 are respectively sleeved at both ends of the transmission rod 402; the sleeves 404 are longitudinally adjustable to the transmission rod 402 through a hydraulic cylinder 401, and the sleeves 404 are fixedly connected to the transverse roller 3 on the same side.
[0056] A transmission rod 402 is provided, which is parallel to the roller axis of the transverse roller 3. After the hydraulic cylinder 401 is activated, the transmission rod 402 can move inside the sleeve 404, and the sleeve 404 moves along the transmission rod 402.
[0057] Preferably, when the two transverse rollers 3 are clamped to the I-beam 1, the two transverse rollers 3 are kept at a certain distance from the web plate 103 of the I-beam and the transverse rollers 3 are in complete contact with the top of the lower flange plate 102 of the I-beam.
[0058] In one embodiment, such as Figure 1 , 8 As shown, a limiting member 403 for controlling the clamping distance of the drive opening and closing device 4 is provided on the transmission rod 402.
[0059] Two limiting members 403 are symmetrically arranged on the transmission rod 402. When the sleeve 404 moves to the position of the limiting member 403 on the transmission rod 402, it stops moving. This effectively prevents the transverse rollers 3 on both sides of the I-beam 1 from being clamped too tightly, which would affect the rolling of the transverse rollers 3 along the lower flange plate 102 of the rolling I-beam. Therefore, after the sleeve 404 moves to the position of the first limiting member 403 on the transmission rod 402, when the drive opening and closing device 4 can no longer compress, the movement of the two transverse rollers 3 from being released from the I-beam 1 and then clamped is completed.
[0060] In one embodiment, such as Figure 1 , 2 As shown, the longitudinal moving mechanism includes a roller frame 14 fixed to the lower end of the vertical adjustment mechanism; the roller frame 14 is equipped with an upper roller 701 and a lower roller 702 respectively placed on the upper and lower sides of the flange plate of the longitudinal track beam 9, and the roller frame 14 is also provided with a longitudinal moving motor 6 for driving the upper roller 701 to move longitudinally along the longitudinal track beam 9.
[0061] Each set of longitudinal rollers 7 is equipped with an upper roller 701 and a lower roller 702. The upper roller 701 supports the top surface of the longitudinal track beam 9, and the lower roller 702 engages with the bottom of the longitudinal track beam 9. The roller frame 14 connects the upper and lower rollers to form a locking structure that synchronously clamps the track. The upper roller 701 bears the vertical load of the platform, and the lower roller 702 provides a reverse restraint force, forming a three-dimensional force system between the longitudinal roller set 7 and the longitudinal track beam 9. This not only provides support for the suspended platform below but also eliminates running gaps, prevents lateral swaying, ensures that the load is evenly distributed on the top and bottom surfaces of the longitudinal track beam 9, reduces local wear, ensures the stability and positioning accuracy of high-altitude operations, extends the service life of the equipment, and restrains the relative displacement between the longitudinal roller set 7 and the longitudinal track beam 9. The roller sets are symmetrically arranged on both sides to form a stable double roller support structure, effectively reducing the load pressure on the rollers on one side.
[0062] In one embodiment, such as Figure 1 , 2 As shown, the longitudinal track beam 9 is provided with limiting baffles 12 at both ends to prevent the upper roller 701 from falling off.
[0063] A limiting baffle 12 is provided on the longitudinal track beam 9 to prevent the longitudinal roller assembly 7 from falling off while rolling along the longitudinal track beam 9, which could cause a serious safety accident. The limiting baffle 12 can be placed at both ends of the longitudinal track beam 9.
[0064] In one embodiment, such as Figure 1 , 2 As shown in Figure 6, the vertical adjustment mechanism includes a retractable connecting rod 5 arranged vertically; the upper end of the retractable connecting rod 5 is fixedly connected to the horizontal moving mechanism, and the lower end is fixedly connected to the vertical moving mechanism.
[0065] The vertical condition mechanism, through the telescopic connecting rod 5, enables vertical length adjustment and can be used in conjunction with the lateral movement mechanism to enable the movement of a single drive system 15 on multiple longitudinally spaced I-beams 1.
[0066] In one embodiment, such as Figure 1 , 4 As shown, the suspended platform includes a suspended platform 8 and suspended platform connecting rods 10 symmetrically distributed on both sides of the longitudinal track beam 9. The upper end of the suspended platform connecting rod 10 is connected to the longitudinal track beam 9, and the lower end is connected to the suspended platform 8.
[0067] Symmetrically distributed suspended platform connecting rods 10 can be set to connect the suspended platform 8 and the longitudinal track beam 9, forming a stable three-dimensional force transmission system. The symmetrical structure improves the overall torsional stiffness, while dispersing stress concentration and extending the service life of the suspended platform connecting rods 10, taking into account both the stability of high-altitude operations and the durability of the equipment.
[0068] In one embodiment, the suspended platform 8 includes an operating platform 11, on which several layers of protective railings 13 are provided.
[0069] Installing guardrails effectively improves the safety of the suspended platform 8. The operating platform 11 and the guardrail 13 form an enclosed working space, effectively preventing personnel from falling. It also provides a stable working surface, reduces psychological stress on personnel, improves maintenance efficiency, and comprehensively ensures safety during high-altitude operations.
[0070] In use, this utility model first moves a single drive system 15. The initial state of the single drive system 15 is a locked state, that is, the transverse rollers 3 on both sides of the I-beam 1 are in a clamping state. Figure 2 As shown, two transverse rollers 3 are engaged with the upper surface of the lower flange plate 102 of the I-beam. When a single drive system 15 needs to move, the drive opening and closing device 4 is adjusted to move the transverse rollers 3 on both sides of the I-beam 1 away from the I-beam 1, and finally detach them from the I-beam 1. Figure 7 As shown, adjust the telescopic connecting rod 5 to move the lateral moving mechanism down below the I-beam 1, start the longitudinal moving motor drive system 6 to drive the longitudinal roller group 7 to move to the next I-beam 1, adjust the telescopic connecting rod 5 again until the bottom ends of the two lateral rollers 3 are at the same level as the lower flange plate 102 of the I-beam, drive the opening and closing device 4 to drive the two lateral rollers 3 to move closer to the I-beam 1 until the two lateral rollers 3 can be engaged on the lower flange plate 102 of the I-beam.
[0071] Preferably, by adjusting the telescopic connecting rod 5, the lateral moving mechanism can be moved down to 20cm below the I-beam 1.
[0072] When the entire utility model is moved, such as Figure 7 As shown, the first drive system 1501 moves forward one segment according to the implementation steps of moving a single drive system 15. The second drive system 1502 and the third drive system 1503 remain locked. After the first drive system 1501 has moved, the second drive system 1502 also moves forward one segment according to the implementation steps of moving a single drive system 15. The first drive system 1501 and the third drive system 1503 remain locked. After the second drive system 1502 has moved, the third drive system 1503 also moves forward one segment according to the implementation steps of moving a single drive system 15. The first drive system 1501 and the second drive system 1502 remain locked. After all drive systems 15 have moved and locked, a safety check is performed, and the basket status is adjusted to the optimal state.
[0073] When the transverse rollers 3 on both sides of the I-beam 1 are in the clamping state, the transverse movement motor drive system 2 is started, and the transverse rollers 3 can move laterally along the lower flange plate 102 of the I-beam to adjust the transverse position of the suspended platform.
[0074] The locking mentioned above refers to the transverse rollers 3 on both sides of the I-beam 1 being in a clamping state; the distance of one segment is the distance between two I-beams 1.
[0075] Preferably, the telescopic connecting rod 5 can be a hydraulically adjustable connecting rod.
[0076] Preferably, after all drive systems 15 have completed movement and locked, the longitudinal motor 6 can be started simultaneously to drive the longitudinal roller group 7 in the reverse direction. By utilizing the friction between the longitudinal track beam 9 and the rollers of the longitudinal roller group 7, the suspended platform can be moved forward by one segment to adjust the balance of the suspended platform.
