Description

Technical Field

[0001] This utility model belongs to the technical field of high-altitude work equipment, specifically relating to a suction cup fixed suspended basket. Background Technology

[0002] In high-altitude operations such as building curtain walls and high-rise glass curtain walls, suspended platforms serve as the core working platform and are widely used in scenarios such as glass installation, curtain wall cleaning, and structural inspection. Their core function is to provide a stable high-altitude operating space for workers and tools. They are fixed to the curtain wall surface through suspension or adsorption, replacing the bulky structure of traditional scaffolding and significantly improving work efficiency and spatial flexibility.

[0003] As shown in the patent with publication number CN216516800U, electric push rods are symmetrically arranged on both sides of the basket. The telescopic ends of the electric push rods extend horizontally and are rigidly connected to the mounting plate. The mounting plate integrates a bidirectional screw mechanism, which drives the sliders on both sides to move closer or further away synchronously by reversing the screws, thereby adjusting the spacing of the suction cup assemblies fixed on the sliders to adapt to glass curtain walls of different widths. A vacuum pump is fixedly installed inside the basket. The vacuum pump is connected to the suction cup assembly through a high-pressure resistant air pipe to provide continuous negative pressure to the suction cups, thereby achieving adsorption and fixation. The suction cup assembly includes a suction cup base, a suction cup, an elastic reset component, and a guide rod. A guide hole is opened in the middle of the suction cup base. One end of the guide rod is fixed to the center of the back of the suction cup, and the other end slides through the guide hole. The elastic reset component is a compression spring, sleeved on the outside of the guide rod, with its two ends abutting against the suction cup base and the suction cup, respectively, to buffer the instantaneous impact when the suction cup contacts the curtain wall.

[0004] However, in actual high-altitude work scenarios, the guide rod's restriction on the suction cup's movement is relatively limited, only allowing the suction cup to move linearly along the guide rod's axis, without enabling fine-tuning of the angle. Before the suspended platform is fixed in place, it will inevitably sway or tilt due to high-altitude gusts of wind. This often results in the suction cup failing to adhere to the curtain wall vertically, instead achieving adhesion at an angle. This tilted adhesion creates continuous stress between the suction cup and the curtain wall, not only compromising sealing stability but also directly reducing the adhesion force, posing a safety hazard to high-altitude operations. Utility Model Content

[0005] This invention addresses the problem that suction cups tend to adhere to curtain walls at an inclined angle, leading to continuous stress and a decrease in adhesion force. It provides a suction cup fixed basket that can effectively reduce the inclination angle of the suction cups, reduce stress, and thus alleviate the trend of decreasing adhesion force.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a suction cup fixed suspended platform, including a platform body, a telescopic cylinder installed on the side of the platform body near the curtain wall, a spring rear seat fixedly connected to the piston rod end of the telescopic cylinder, a spring front seat provided on the outer side of the spring rear seat, and the spring front seat and the spring rear seat are arranged opposite to each other; both the spring front seat and the spring rear seat have corresponding grooves inside, and a slider is slidably arranged in each groove; corresponding connecting holes are opened on the opposite surfaces of the spring front seat and the spring rear seat, and each connecting hole is connected to the corresponding groove; a connecting rod is provided between the spring front seat and the spring rear seat, with both ends of the connecting rod passing through two connecting holes and respectively hinged to the slider ball in their respective grooves; the grooves are provided with a moving space for the slider that cooperates with them; a buffer spring is sleeved on the outer side of the connecting rod, and both ends of the buffer spring abut against the spring front seat and the spring rear seat respectively; a suction cup is installed on the side of the spring front seat away from the spring rear seat, and the suction cup is connected to an air pump through a negative pressure air pipe, and the air pump is fixedly installed inside the platform body.

[0007] In this technical solution, a spring rear seat is fixedly connected to the piston rod end of the telescopic cylinder. A spring front seat is located on the outer side of the spring rear seat. Corresponding grooves are formed inside both the spring front and rear seats, and a slider is slidably mounted in each groove. Corresponding connecting holes are formed on the opposite surfaces of the spring front and rear seats. The two ends of the connecting rod pass through two connecting holes and are respectively ball-jointed with the sliders in their respective grooves. A buffer spring is fitted on the outer side of the connecting rod. A suction cup is installed on the side of the spring front seat away from the spring rear seat, and the suction cup is connected to the air pump. When fixing the suspended platform, the telescopic cylinder controls the suction cup to move towards the curtain wall. When the suction cup contacts the curtain wall, the air pump is activated to create negative pressure on the suction cup, causing it to adhere and fix to the curtain wall. Even if the suction cup tilts during adhesion, the connecting rod adjusts the axis of the suction cup through the ball-joint structures at both ends, thereby reducing the tilt angle. Therefore, this device can effectively reduce the tilt angle of the suction cup, reduce stress, and thus alleviate the decreasing trend of the adhesion force.

[0008] Furthermore, the connecting rod and the connecting hole are in a clearance fit, with rounded corners at both ends of the connecting hole. This clearance fit provides the connecting rod with necessary room for movement, allowing it to swing freely with the ball joint structure when the suction cup is tilted. This avoids movement jamming caused by excessive tightness, ensuring smooth adjustment of the suction cup angle by the ball joint, thus effectively adapting to the tilted contact state between the suction cup and the curtain wall. The rounded corners at both ends of the connecting hole eliminate sharp edges at the opening. When the connecting rod swings or moves, it prevents rigid scraping or squeezing between the connecting rod surface and the right-angle edge of the opening, reducing friction and wear. At the same time, the rounded corners disperse stress concentration at the opening, preventing cracks from appearing at the edge of the connecting hole after long-term stress, and extending the structural life of the spring front and spring rear seats.

[0009] Furthermore, locating bosses are fixed on the opposing surfaces of the front and rear spring seats, with the two locating bosses positioned correspondingly. The axis of the locating bosses coincides with the center line of the connecting hole, and the two locating bosses are respectively inserted into the two ends of the buffer spring. The locating bosses, inserted into the two ends of the buffer spring, can limit the radial wobble of the spring during compression or extension by engaging with the inner coil of the spring through the outer circumference of the bosses. This ensures that the spring always extends and retracts along its own axis, avoiding the failure of the buffering effect or localized stress concentration caused by spring misalignment.

[0010] Furthermore, each slider has a ball socket on its side near the corresponding connecting hole, and a ball head is installed inside the ball socket. The ball head is fixedly connected to the end of the corresponding connecting rod. When the suction cup contacts the curtain wall, it tilts due to the swaying of the scaffold. The ball head can rotate flexibly within the ball socket, driving the connecting rod to deflect around the slider in multiple directions. This rotational freedom can adapt to the tilt state of the suction cup and the curtain wall surface in real time. By adjusting the angle of the connecting rod, the posture of the suction cup is corrected, making the sealing lip of the suction cup fit the curtain wall more closely and reducing local gaps caused by tilting.

[0011] Furthermore, the air pump is a dual-purpose positive and negative pressure air pump. By adopting this dual-purpose air pump, both negative and positive pressure functions can be integrated into a single unit, eliminating the need for separate power equipment for a vacuum pump and an air compressor. This integrated design reduces the overall number of power equipment, and also reduces the number of auxiliary components such as piping, connectors, and mounting brackets, thereby significantly reducing the weight of the entire power system and achieving a lightweight effect.

[0012] Furthermore, the telescopic cylinder is connected to the air pump via a positive pressure air pipe, which is equipped with a positive pressure air tank. The positive pressure air tank stores a certain amount of compressed air, stabilizing the air pressure within the positive pressure air pipe during normal air pump operation. This reduces pressure fluctuations caused by air pump output fluctuations, resulting in smoother telescopic cylinder movement. In the event of a power outage or other emergency causing the air pump to stop working, the compressed air stored in the tank continuously provides pressure to the telescopic cylinder, preventing it from contracting due to instantaneous pressure loss. This maintains stable contact between the suction cup and the curtain wall, buying time for emergency response and improving the safety of the suspended platform in unexpected situations.

[0013] Furthermore, a negative pressure gas storage tank is installed on the negative pressure air pipe between the suction cup and the air pump. The negative pressure gas storage tank can store a certain amount of negative pressure gas. During normal operation of the air pump, it can balance pressure fluctuations within the negative pressure air pipe, making the negative pressure state at the suction cup more stable. This prevents the suction force of the suction cup from fluctuating due to unstable air pump output pressure, thus ensuring the firmness of the suction cup's adhesion to the curtain wall. When the air pump stops working due to power outages or other situations, the negative pressure stored in the gas storage tank can continuously maintain the negative pressure environment at the suction cup, preventing the suction cup from detaching from the curtain wall due to instantaneous pressure loss.

[0014] Furthermore, a vacuum filter is installed on the negative pressure air pipe between the suction cup and the air pump, located between the negative pressure air tank and the air pump. Dust, fine particles from the air, or tiny impurities brought in by the suction cup when adsorbing the curtain wall may get into the negative pressure air pipe. If these impurities directly enter the air pump, they will wear down critical components such as the cylinders and valves inside the pump, leading to abnormal operation, reduced efficiency, and even shortened service life. The vacuum filter can intercept these impurities in advance, preventing them from entering the air pump, maintaining its normal operating condition, and reducing the occurrence of malfunctions.

[0015] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: First, adaptive leveling and tilt angle control: When the suction cup contacts the curtain wall and tilts, the two ends of the connecting rod are connected to the slider through a ball joint structure, which can adaptively adjust the angle in multiple directions, automatically correct the posture of the suction cup axis, effectively reduce tilt, and ensure that the adsorption surface is fully in contact with the curtain wall. Second, reduced local stress and improved structural reliability: The buffer spring and the ball joint connecting rod work together to absorb and alleviate the impact and stress concentration caused by position deviation or unevenness of the curtain wall, reduce component wear and deformation, and extend the service life of the device. Finally, maintaining stable adsorption force and enhancing safety: By reducing tilt and stress, the suction cup is less prone to air leakage or local failure, and the adsorption force distribution is more uniform, thereby significantly alleviating the downward trend of adsorption force and improving the stability and operational safety of the suspended platform fixing process.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] A suction cup fixed basket, such as Figure 1 As shown, the system includes a suspended platform body 1, which is a metal frame. Telescopic cylinders 2 are fixedly installed on the side of the suspended platform body 1 near the curtain wall. The telescopic cylinders 2 are horizontally positioned, with their piston rods extending outwards from the suspended platform body 1 and perpendicular to the curtain wall plane. There are four telescopic cylinders 2 arranged in a rectangular array of two rows and two columns. A suction cup 3 is provided at the end of the piston rod of the telescopic cylinder 2, and a pressure sensor is installed on the suction cup 3. The suction cup 3 can adhere to the curtain wall, thereby limiting the position of the suspended platform body 1. A buffer mechanism is provided between the suction cup 3 and the end of the piston rod of the telescopic cylinder 2. The buffer mechanism can both alleviate the impact force generated when the suction cup 3 adheres to the curtain wall and adjust the tilt angle of the suction cup 3 to reduce internal stress.

[0021] like Figure 3-5 As shown, in this specific embodiment, the buffer mechanism includes a spring rear seat 4 and a spring front seat 5. The spring front seat 5 is located outside the spring rear seat 4 and is arranged opposite to the spring rear seat 4. The spring rear seat 4 is fixedly connected to the piston rod end of the telescopic cylinder 2 by bolts. Corresponding sliding grooves 6 are formed inside the opposite sides of the spring front seat 5 and the spring rear seat 4. Both sliding grooves 6 are horizontally arranged and have the same cross-sectional diameter. A slider 61 is slidably disposed in each sliding groove 6, and the slider 61 can slide along the corresponding sliding groove 6.

[0022] The front spring seat 5 and the rear spring seat 4 are respectively provided with corresponding connecting holes 62. Each connecting hole 62 is connected to the corresponding sliding groove 6 and the two are set on the same center line. The diameter of the connecting hole 62 is smaller than the cross-sectional diameter of the sliding groove 6, and each connecting hole 62 has rounded corners at both ends.

[0023] A connecting rod 63 is provided between the spring front seat 5 and the spring rear seat 4. The two ends of the connecting rod 63 pass through two connecting holes 62 respectively and are respectively ball-hinged with the sliders 61 in their respective slide grooves 6. The slide grooves 6 are provided with a moving space for the sliders 61 that cooperate with them. Specifically, each slider 61 has a ball socket 65 on its side near the corresponding connecting hole 62. A ball head 64 is installed in the ball socket 65. The ball head 64 is welded to the end of the corresponding connecting rod 63, and the connecting rod 63 and the connecting hole 62 are in clearance fit.

[0024] In this embodiment, the connecting rod 63 is composed of two detachably connected round rods. One end of one round rod is welded to a ball head 64, and the other end has an integrally formed reduced-diameter section with external threads machined on its outer circumference. One end of the other round rod is welded to another ball head 64, and the other end has an axially formed inner hole with an internal thread that matches the external thread. During assembly, the two round rods can be inserted into the inner hole of the second round rod through the reduced-diameter section of the first round rod, and the detachable fixed connection is achieved through the threaded engagement of the external and internal threads. The specific installation process is as follows: First, weld and fix the two round rods to the corresponding ball heads 64 to form two rod assemblies with ball heads 64; then, install the ball heads 64 of the two assemblies into the corresponding sliders 61 and into the corresponding grooves 6, so that the ends of the two round rods away from the ball heads 64 pass through the corresponding connecting holes 62; finally, align the reduced diameter section of the first round rod with the inner hole of the second round rod, and fix the two round rods by screwing them together to complete the overall assembly of the connecting rod 63.

[0025] A buffer spring 7 is sleeved on the outer side of the connecting rod 63. The two ends of the buffer spring 7 abut against the front spring seat 5 and the rear spring seat 4, respectively. Positioning bosses 71 are fixed on the opposite surfaces of the front spring seat 5 and the rear spring seat 4. The two positioning bosses 71 are in corresponding positions and their axes coincide with the center line of the connecting hole 62. The two positioning bosses 71 are respectively inserted into the two ends of the buffer spring 7. The positioning bosses 71 and the corresponding front spring seat 5 or rear spring seat 4 are integrally machined, and the height of the positioning bosses 71 is less than one-third of the original length of the buffer spring 7.

[0026] The front spring seat 5 is fixedly connected to the suction cup 3 by bolts on the side away from the rear spring seat 4. The suction cup 3 is connected to the air pump 11 through the negative pressure air pipe 31. The air pump 11 is a dual-purpose positive and negative pressure air pump 11 and is fixedly installed inside the main body 1 of the basket. The negative pressure air pipe 31 is connected to the negative pressure output end of the air pump 11. A negative pressure control valve and a negative pressure storage tank 13 are sequentially provided on the negative pressure air pipe 31 between the suction cup 3 and the air pump 11. The negative pressure control valve is located between the suction cup 3 and the negative pressure storage tank 13 and is used to control the start and stop of the negative pressure adsorption of the suction cup 3. A vacuum filter 14 is also provided on the negative pressure air pipe 31. The vacuum filter 14 is located between the negative pressure storage tank 13 and the air pump 11.

[0027] The positive pressure output end of the air pump 11 is connected to a positive pressure air pipe 21. The positive pressure air pipe 21 is provided with a triple unit, a positive pressure air tank 12 and a telescopic control valve in sequence along the air delivery direction. The triple unit is an integrated device of filter, pressure reducing valve and oil mist lubricator, which is existing equipment. The positive pressure air tank 12 can store a certain amount of compressed air. When the air pump 11 stops working due to sudden situations such as power failure, the compressed air stored in the positive pressure air tank 12 can continuously provide pressure to the telescopic cylinder 2, preventing the telescopic cylinder 2 from contracting due to instantaneous pressure loss, thereby maintaining the stable contact state between the suction cup 3 and the curtain wall. The telescopic control valve is used to control the extension or retraction of the piston rod of the telescopic cylinder 2. After the positive pressure air pipe 21 is led out from the telescopic control valve, it is divided into an extension air pipe and a retraction air pipe. The extension air pipe and the retraction air pipe are respectively connected to the extension action air inlet and the retraction action air inlet of the telescopic cylinder 2.

[0028] The specific operating process is as follows: In the initial state, the piston rod of the telescopic cylinder 2 is fully retracted, and the spring rear seat 4, which is fixed to the piston rod, is close to the main body 1 of the basket; the buffer spring 7 is sleeved on the outside of the positioning boss 71 and pre-compressed by 50mm, and the positioning boss 71 restricts its radial displacement; in the sliding grooves 6 of the spring front seat 5 and the spring rear seat 4, the slider 61 is close to the corresponding connecting hole 62, and the connecting rod 63 is connected to the slider 61 through a ball joint structure, and the connecting rod 63 and the connecting hole 62 are in clearance fit. The air pump 11 is a dual-purpose positive and negative pressure device, and its positive pressure output end and negative pressure output end are respectively connected to the corresponding air circuit system and are in a ready-to-start state.

[0029] like Figure 2 As shown, during operation, the main body 1 of the suspended platform is first moved to the working position on the curtain wall, ensuring that the four telescopic cylinders 2 are aligned with the adsorption area. The air pump 11 is started, and its positive pressure output end and negative pressure output end work simultaneously: the positive pressure side outputs compressed air through the positive pressure air pipe 21, which is first filtered, pressure regulated and lubricated by the triple unit, and then pressurized by the positive pressure air tank 12. The air is then controlled by the telescopic control valve to enter the air inlet of the telescopic cylinder 2 to drive the piston rod to extend; the piston rod drives the spring rear seat 4 to move towards the curtain wall, and pushes the spring front seat 5 through the buffer spring 7. The connecting rod 63 drives the spring front seat 5 and the suction cup 3 to move towards the curtain wall synchronously through the ball joint structure. The positioning boss 71 always restricts the tilt of the buffer spring 7.

[0030] When the sealing lip of suction cup 3 contacts the curtain wall, the reaction force triggers the pressure sensor, and the control system immediately opens the negative pressure control valve. At this time, the air pump 11 continuously draws air from the negative pressure side, forming a negative pressure airflow through the negative pressure air pipe 31. The airflow first passes through the vacuum filter 14 to intercept impurities, then enters the negative pressure storage tank 13 for storage, and subsequently acts on suction cup 3 through the negative pressure control valve, creating a negative pressure inside suction cup 3 and causing it to adhere to the curtain wall. Simultaneously, the reaction force of suction cup 3 pushes the spring front seat 5 to compress the buffer spring 7. The slider 61 inside the spring front seat 5 slides along the slide groove 6 away from the connecting hole 62, providing stroke for spring compression.

[0031] The pressure sensor monitors the negative pressure of suction cup 3 in real time. When the preset value is reached, the negative pressure control valve is closed, and the negative pressure storage tank 13 maintains the negative pressure. If the negative pressure is insufficient, the negative pressure control valve is reopened to replenish the pressure. During this process, the air pump 11 continuously outputs negative pressure. The positive pressure system maintains its working state synchronously, and the positive pressure storage tank 12 continuously provides stable pressure to the telescopic cylinder 2. If the suction cup 3 tilts due to the swaying of the hanging basket, the ball head 64 at one end of the connecting rod 63 will rotate flexibly within the ball socket 65 of the slider 61, causing the connecting rod 63 to deflect in multiple directions around the slider 61. This multi-directional rotational freedom can adapt to the tilt state of the suction cup 3 when it contacts the curtain wall in real time. The posture of the suction cup 3 is gradually corrected by adjusting the angle of the connecting rod 63. At the same time, the clearance between the connecting rod 63 and the connecting hole 62 avoids jamming during deflection, ultimately allowing the sealing lip of the suction cup 3 to fit more fully against the curtain wall and reducing local gaps caused by tilting. During this period, the slider 61 will also slide slightly along the slide groove 6, cooperating with the posture adjustment of the spring front seat 5. The buffer spring 7 will also partially extend and retract with the posture change, while the positioning boss 71 always limits the radial displacement of the spring, ensuring the stability of the adjustment process.

[0032] After the operation is completed, close the negative pressure control valve and open the exhaust channel to release the negative pressure of suction cup 3. At the same time, the telescopic control valve switches the airflow direction, and positive pressure enters the air inlet of the telescopic cylinder 2 to drive the piston rod to retract, thereby resetting the spring rear seat 4, buffer spring 7, spring front seat 5, suction cup 3 and connecting rod 63. The slider 61 returns to the initial position of the slide groove 6, the buffer spring 7 returns to the pre-compression state, the air pump 11 stops working, and the device returns to standby.

[0033] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: First, adaptive leveling and tilt angle control: When the suction cup contacts the curtain wall and tilts, the two ends of the connecting rod are connected to the slider through a ball joint structure, which can adaptively adjust the angle in multiple directions, automatically correct the posture of the suction cup axis, effectively reduce tilt, and ensure that the adsorption surface is fully in contact with the curtain wall. Second, reduced local stress and improved structural reliability: The buffer spring and the ball joint connecting rod work together to absorb and alleviate the impact and stress concentration caused by position deviation or unevenness of the curtain wall, reduce component wear and deformation, and extend the service life of the device. Finally, maintaining stable adsorption force and enhancing safety: By reducing tilt and stress, the suction cup is less prone to air leakage or local failure, and the adsorption force distribution is more uniform, thereby significantly alleviating the downward trend of adsorption force and improving the stability and operational safety of the suspended platform fixing process.
