Description

Technical Field

[0001] This invention relates to the field of suspended platform technology, and in particular to a suspended platform for high-altitude operations with an overload detection mechanism and a method for constructing the suspended platform. Background Technology

[0002] Currently, suspended platforms for high-altitude operations are key equipment in fields such as building exterior wall construction, curtain wall installation, and high-altitude maintenance, and their safety and reliability have received widespread attention. Existing technologies, such as the "Overload Monitoring Safety Device for Suspended Platforms for High-Altitude Operations" disclosed in Chinese Patent CN208716789U, utilize pressure sensors installed between the rear support and counterweight of the suspended platform's suspension mechanism to collect counterweight pressure and calculate the anti-overturning moment. Simultaneously, tension sensors are installed on the working wire rope to acquire real-time wire rope tension data. Both signals are transmitted to a data processing module, where a built-in CPU calculates the actual load and overturning moment of the suspended platform based on a preset algorithm. When overload or torque imbalance is detected, an audible and visual alarm is immediately triggered, and the hoist control circuit can be switched off, thus achieving online real-time overload detection and safety protection. This solution improves the safety of suspended platform operations to a certain extent.

[0003] However, the aforementioned existing technologies still have significant shortcomings in practical applications. On the one hand, the solution only focuses on overload detection and alarm control, without considering the risks of corrosion, jamming, and short circuits caused by moisture and impurities adhering to the surface of the wire rope when the suspended platform operates in high humidity, rainy, or dusty environments for extended periods. On the other hand, the wire rope lacks effective dewatering, dust removal, and drying treatment before entering the hoist. Moisture and impurities are easily carried into the rope inlet with the wire rope, leading to increased mechanical wear and electrical failure rates within the hoist. In severe cases, this can even cause wire rope slippage or breakage, affecting the overall service life of the suspended platform and operational safety.

[0004] In addition, in existing suspended platform equipment, the motor of the hoist is prone to generating a lot of heat under high load or continuous operation conditions. If it cannot be dissipated in a timely and effective manner, the motor temperature will rise too high, which will affect the output efficiency and operational stability of the hoist. Traditional heat dissipation methods mostly rely on natural cooling, which has limited cooling effect and lacks an intelligent cooling mechanism that is linked to the working status of the suspended platform itself. Summary of the Invention

[0005] The purpose of this invention is to address the risks of corrosion, jamming, and short circuits caused by moisture and impurities adhering to the surface of the wire rope to the internal parts of the hoist when the hoist operates in high humidity, rainy weather, or dusty environments for a long time. This invention proposes a high-altitude work hoist with an overload detection mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-altitude work platform with an overload detection mechanism, comprising: a platform and a steel rope, wherein a hoist and an electrical control box are installed on the platform, the hoist is provided with a rope inlet, and a water removal structure and a cooling structure are installed on the hoist, wherein the water removal structure is used to treat the steel rope.

[0007] As a further embodiment of the present invention, the water removal structure includes a treatment box fixed to the top of the elevator, collection boxes connected to both sides of the treatment box, and two sets of sponges and iron plates placed vertically inside the treatment box. The sponges have empty slots, and the inner side of the empty slots is an insert block. The iron plates are fixed with receiving blocks. The receiving blocks are inserted into the empty slots, and then the insert blocks come into the receiving blocks. The insert blocks and the receiving blocks are connected by a No. 1 spring. The sponges have baffle grooves. The baffle grooves pass through the top of the sponges, the empty slots, the receiving blocks, and the insert blocks to the bottom of the sponges. A baffle bar is inserted into the baffle groove on the upper sponge. The collection box is equipped with a magnet that cooperates with the iron plates.

[0008] As a further solution of the present invention, the steel rope is dehydrated and dehumidified by "sponge adsorption and dehydration + hot air drying". The sponge can quickly intercept most of the liquid water and impurities, preventing water from directly entering the hoist and causing rust, jamming and short circuit. Then, the residual heat of the motor and the airflow of the rotating blades are used to completely remove the residual moisture, which significantly improves the service life of the equipment, the stability of operation and the safety of high-altitude operations.

[0009] As a further embodiment of the present invention, the dewatering structure also includes a drying trough hidden below the rope inlet of the hoist. The drying trough is rotatably connected to a rotating shaft. Blades and a No. 1 pulley are fixed at both ends of the rotating shaft, respectively. The blades are located inside the drying trough. The drying trough is provided with an air inlet pipe. One end of the air inlet pipe is located at the motor of the hoist, which is used to collect the heat of the motor to dry the steel rope.

[0010] As a further embodiment of the present invention, a support rod is fixed to the top of the processing box, and a guide wheel is rotatably connected to the support rod. The center of the guide wheel is raised and a second pulley is fixed after passing through the support rod. The first pulley and the second pulley are driven by a belt.

[0011] As a further embodiment of the present invention, the groove of the guide wheel is provided with a friction surface, and the friction surface of the groove is in contact with the steel rope.

[0012] As a further embodiment of the present invention, the cooling structure includes a bent rod slidably connected to the top of the collection box, the bottom end of the bent rod being located at the top of the collection box and fixed with a pressure plate, the top of the collection box being connected to the bent rod via a second spring, a limiting rod slidably connected to the side of the collection box, the bottom end of the limiting rod passing through a magnet, a slot being provided at one end of the bent rod, the top end of the limiting rod being inserted into the slot, and the second spring being stretched to store elastic potential energy.

[0013] As a further embodiment of the present invention, a water collection box is fixed to the outside of the hoist, and the bottom of the collection box is connected to the water collection box through a drain pipe.

[0014] As a further embodiment of the present invention, the cooling structure is linked with a differential assembly, the differential assembly including a sealing plate slidably connected to the collection box and the processing box, a hollow block fixed to the top of the sealing plate, a slot for the bottom of the collection box to be inserted into, a limit block fixed to the top of the bent rod, the limit block being inserted into the hollow block, a vertical plate fixed to the top of the collection box, an elastic baffle fixed to the top of the vertical plate, and a pressure block fixed to the side of the bent rod.

[0015] As a further embodiment of the present invention, the cooling structure also includes an airbag installed on the side wall of the water collection box. One side of the airbag is arc-shaped and adapted to the outline of the motor of the hoist. The airbag is fixed with a top block.

[0016] As a further embodiment of the present invention, a support block is fixed to the side wall of the water collection box, a push-button switch is installed on the support block, and an electric atomizing nozzle is installed at the bottom of the water collection box. The push-button switch and the electric atomizing nozzle are connected by a wire.

[0017] A method for constructing a suspended platform for high-altitude operations with an overload detection mechanism includes the following steps: Step 1: Equipment Installation and Inspection: Suspend the basket at the working position, pass the steel rope through the processing box and the rope inlet of the hoist, and confirm that the upper sponge is in the initial compressed state, the stop bar is inserted into the stop groove, the limit bar is inserted into the slot, and the second spring is in the stretched state.

[0018] Step 2: Water and dust removal: Start the hoist. The sponge below absorbs and removes moisture and impurities from the surface of the steel rope. The steel rope passes through the drying tank and is driven by the guide wheel to rotate the blades. At the same time, the air inlet pipe collects the heat from the motor and sends it into the drying tank for secondary hot air drying of the steel rope.

[0019] Step 3: Automatic replacement and squeezing of saturated sponge: After saturation, the sponge is drawn into the collection box by a magnet, triggering the limit rod to disengage from the slot. The second spring drives the bent rod to descend, and the sealing plate falls first to close the treatment box and the collection box. The bent rod drives the pressure plate to squeeze the sponge and squeeze the water into the water collection box through the drain pipe. At the same time, the upper sponge falls back to its original position and expands, automatically taking over the water absorption work.

[0020] Step 4: Motor temperature adaptive cooling: When the motor temperature rises to the preset threshold, the airbag expands due to heat, driving the top block to trigger the button switch. The electric atomizing nozzle sprays water from the water collection box onto the motor surface to cool it down. After the temperature drops, the airbag contracts and resets, and the electric atomizing nozzle stops spraying.

[0021] The present invention proposes a suspended platform for high-altitude operations with an overload detection mechanism and a method for constructing the suspended platform. The beneficial effects are as follows: 1. Existing technologies often lack effective dehydration, dust removal, and drying treatment for wire ropes before they enter the hoist, leading to problems such as rust, jamming, and short circuits caused by moisture and impurities being easily introduced into the hoist. This invention addresses these issues by incorporating a dehydration structure. A sponge in the treatment box initially absorbs water and removes dust from the wire rope. A magnet and iron plate automatically draw the saturated sponge into the collection box, while a spring-loaded mechanism automatically replaces the sponge. Furthermore, a drying tank, blades, and air inlet pipe utilize the heat generated by the hoist motor to perform a secondary hot air drying process on the dehydrated wire rope. This dual treatment of sponge adsorption and hot air drying effectively removes liquid water, moisture, and fine particulate impurities from the wire rope surface, significantly reducing the risk of corrosion and wear on internal hoist components. This greatly improves equipment connection stability, operational stability, and service life, ensuring safety during high-altitude operations.

[0022] 2. This invention addresses the problems of excessive temperature rise in hoist motors under high load or continuous operation conditions, limited effectiveness of traditional heat dissipation methods, and the lack of a coordinated cooling mechanism in existing technologies. By incorporating a cooling structure, the water squeezed from a saturated sponge is collected in a water collection box via a drain pipe. Simultaneously, an airbag, top block, push-button switch, and electric atomizing nozzle work together. When the motor temperature rises to a preset threshold, the internal medium of the airbag expands due to heat, driving the top block to trigger the push-button switch. This causes the electric atomizing nozzle to spray water from the collection box onto the motor surface for precise cooling. During this process, a sealing plate preferentially falls and inserts into the slot to completely isolate the processing box and the collection box, ensuring that water does not flow back into the processing box during the squeezing operation and preventing secondary malfunctions caused by water seepage. Furthermore, the system automatically starts and stops based on motor temperature without manual intervention, achieving temperature-adaptive closed-loop cooling control and effectively recycling the water collected during the dewatering process, avoiding resource waste.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0027] This invention proposes a suspended platform for high-altitude operations with an overload detection mechanism, comprising: a suspended platform 1, a steel rope 2, a hoist 3 and an electrical control box 4 installed on the suspended platform 1, and the hoist 3 being provided with a rope inlet 5.

[0028] Furthermore, the working principle of the overload detection mechanism has been fully disclosed in the cited prior art. Those skilled in the art can directly adapt the existing overload detection technology to the suspended platform electrical control system and hoist control circuit of the present invention. Given that it is a mature existing technology, the present invention will not elaborate on its specific structure and working process here.

[0029] Specifically, the hoist 3 is equipped with a water removal structure for treating the steel rope 2. The water removal structure includes a treatment box 6 fixed to the top of the hoist 3, and collection boxes 7 connected to both sides of the treatment box 6. The treatment box 6 contains two sets of sponges 8 and iron plates 9 placed vertically inside. The sponges 8 have empty slots 10, and the inner side of the empty slots 10 is a block 11. The iron plates 9 are fixed with receiving blocks 12. The receiving blocks 12 are inserted into the empty slots 10, and then the block 11 is placed into the receiving blocks 12. The block 11 and the receiving blocks 12 are connected by a spring 13. The sponges 8 have a baffle groove 14. The baffle groove 14 passes through the top of the sponges 8, the empty slots 10, the receiving blocks 12, and the block 11 before reaching the bottom of the sponges 8. A baffle bar 15 is inserted into the baffle groove 14 on the upper part of the sponges 8. The collection box 7 contains a magnet 16 that cooperates with the iron plates 9.

[0030] Furthermore, the dewatering structure also includes a drying trough 17 hidden below the rope inlet 5 of the hoist 3. The drying trough 17 is rotatably connected to a rotating shaft 18. The two ends of the rotating shaft 18 are respectively fixed with blades 19 and a first pulley 20. The blades 19 are located inside the drying trough 17. The drying trough 17 is provided with an air inlet pipe 21 and an exhaust port. One end of the air inlet pipe 21 is located at the motor of the hoist 3, which is used to collect the heat of the motor to dry the steel rope 2.

[0031] Furthermore, both the intake pipe 21 and the exhaust port are equipped with stainless steel woven protective mesh. The protective mesh is made of 304 stainless steel fine wires and is precisely woven. The mesh is fine and uniform, with good air permeability and structural strength, allowing only gas to pass through and preventing impurities from entering.

[0032] Furthermore, a support rod 22 is fixed to the top of the processing box 6, and a guide wheel 23 is rotatably connected to the support rod 22. The center of the guide wheel 23 is raised and a second pulley 24 is fixed after passing through the support rod 22. The first pulley 20 and the second pulley 24 are driven by a belt 25.

[0033] Furthermore, the groove of the guide wheel 23 is provided with a friction surface, and the friction surface of the groove is in contact with the steel rope 2.

[0034] The working process of the above-mentioned water removal structure is as follows: In the initial state, open the transparent cover on the treatment box 6, and then place two abutting sponges 8 under the treatment box 6. Since the two sponges 8 at the bottom are abutting each other, they will maintain their current position. Figure 6 (as shown) Then, manually squeeze the other two sponges 8 and place them on the lower sponge 8. By squeezing, the first spring 13 inside the upper sponge 8 is compressed. After the sponge, the insert block 11, and the retaining groove 14 on the receiving block 12 are aligned, manually insert the stop bar 15 from the top of the processing box 6. The stop bar 15 passes through the retaining groove 14 and restricts the first spring 13 to the compressed state, keeping the upper sponge 8 compressed and not reset, and the inner arc-shaped opening separate from the steel rope 2. The two lower sponges 8 are not restricted by the stop bar 15, and they press against each other and the inner arc-shaped opening is tightly attached to the steel rope 2, which is convenient for absorbing the moisture on the steel rope 2. When the hoist 3 climbs along the steel rope 2 and lifts the basket 1 to work, the sponge 8 below moves on the outside of the steel rope 2 to absorb moisture and leave behind dust and other fine particles of impurities on the steel rope 2. This operation can prevent moisture from corroding the internal parts of the hoist 3 and impurities from causing rope jamming failure, thus ensuring the life of the equipment and the safety of high-altitude operations. As the lower sponge 8 absorbs water and gradually moves downwards, reaching the saturation threshold, it comes to the bottom of the processing box 6. This is to prepare for collecting the sponge 8. The magnet 16 inside the collection box 7 magnetically attracts the iron plate 9 on the sponge 8, drawing the saturated sponge 8 into the collection box 7 for collection. At this time, the upper sponge 8 falls back to its original lower position, the stop bar 15 disengages from the stop groove 14, and the first spring 13 releases its elasticity to restore the compressed sponge 8 and expand it. The arc-shaped opening automatically fits the steel rope 2 to take over the water absorption work. The transparent cover of the processing box 6 allows workers to observe and replace the new sponge 8, achieving cyclical water and impurity removal. After the initial dehydration and dust removal, the steel rope 2 enters the drying tank 17. The friction surface inside the guide wheel 23 is in contact with the steel rope 2, so when the hoist 3 climbs, it will drive the second pulley 24 to rotate. The first pulley 20 is driven by the belt 25, and then the blade 19 is driven to rotate by the rotating shaft 18. At the same time, the air inlet pipe 21 collects the heat generated by the working motor of the hoist and sends it into the drying tank 17 to dry the dehydrated steel rope 2. The rotation of the blade 19 accelerates the hot air circulation and performs secondary drying on the residual moisture of the steel rope 2. The exhaust port of the drying tank 17 discharges the humid exhaust gas in time. By using two steps—"sponge 8 adsorption and dehumidification + hot air drying"—the steel rope 2 is dehydrated and dehumidified. First, the sponge 8 quickly traps most of the liquid water and impurities, preventing moisture from directly entering the hoist and causing corrosion, jamming, or short circuits. Then, the residual heat of the motor and the airflow from the rotating blades 19 are used to thoroughly remove residual moisture. This dual protection significantly reduces the probability of corrosion and wear on the internal parts of the hoist 3 caused by the steel rope 2, and significantly improves the service life, operational stability, and safety of high-altitude operations.

[0035] Next, a cooling structure is installed on the elevator 3. The cooling structure includes a bent rod 26 slidably connected to the top of the collection box 7. The bottom end of the bent rod 26 is located at the top of the collection box 7 and is fixed with a pressure plate 30. The top of the collection box 7 is connected to the bent rod 26 by a second spring 27. A limiting rod 28 is slidably connected to the side of the collection box 7. The bottom end of the limiting rod 28 passes through a magnet 16. A slot 29 is provided at one end of the bent rod 26. The top end of the limiting rod 28 is inserted into the slot 29. The second spring 27 is stretched to store elastic potential energy.

[0036] Next, a water collection box 37 is fixed to the outside of the elevator 3, and the bottom of the collection box 7 is connected to the water collection box 37 through a drain pipe 43.

[0037] Next, the cooling structure is linked with a differential assembly, which includes a sealing plate 31 that is slidably connected to the collection box 7 and the processing box 6. A hollow block 32 is fixed to the top of the sealing plate 31, and a slot 44 is provided at the bottom of the collection box 7 for the bottom of the sealing plate 31 to be inserted. A limit block 33 is fixed to the top of the bent rod 26 and is inserted into the hollow block 32.

[0038] Next, a vertical plate 34 is fixed to the top of the collection box 7, an elastic baffle 35 is fixed to the top of the vertical plate 34, and a pressure block 36 is fixed to the side of the bent rod 26.

[0039] The next step is that the cooling structure also includes an airbag 38 installed on the side wall of the water collection box 37. One side of the airbag 38 is arc-shaped and adapted to the motor outline of the elevator 3. The airbag 38 is fixed with a top block 39.

[0040] Next, a support block 40 is fixed to the side wall of the water collection box 37, a push-button switch 41 is installed on the support block 40, and an electric atomizing nozzle 42 is installed at the bottom of the water collection box 37. The push-button switch 41 and the electric atomizing nozzle 42 are connected by a wire.

[0041] When the iron piece 9 is attracted by the magnet 16 in the collection box 7, the iron piece 9 will directly hit the end of the limiting rod 28 located at the position of the magnet 16, causing the limiting rod 28 to disengage from the slot 29 of the bent rod 26. The pre-stretched second spring 27 will release its rebound force instantly and drive the bent rod 26 to descend. Since the limiting block 33 has moderate elasticity, it can be stably inserted into the hollow block 32 under normal conditions and support the sealing plate 31 to remain stationary and prevent it from descending to achieve the limiting. Under the strong rebound force of the second spring 27, the limiting block 33 is bent and deformed by force and forcibly falls out from the hollow block 32. When the bent rod 26 descends, the pressure block 36 on its side passes through two sets of elastic baffles 35 in sequence. After the elastic baffles 35 are deformed and bent, the pressure block 36 will pass through the elastic baffles 35. The purpose is to slow down the descent speed of the bent rod 26 through the resistance of the elastic baffles 35, so that the descent speed of the sealing plate 31 is greater than that of the bent rod 26 to form a differential speed. The sealing plate 31 falls down and is inserted into the slot 44 to completely block and seal the treatment box 6 and the collection box 7, preventing water from entering the treatment box 6 during subsequent squeezing and then coming to the elevator 3 through the rope inlet 5, causing damage. Subsequently, the bent rod 26 drives the pressure plate 30 to continue to descend and compress the sponge 8 that has absorbed water to saturation, squeezing out the water stored inside the sponge 8. The squeezed-out water flows into the water collection box 37 through the drain pipe 43 (the drain pipe 43 is equipped with a filter screen to prevent small impurities from entering the water collection box 37) to complete centralized collection, realizing the continuous linkage of water removal, water squeezing and water collection. When the operating temperature of the motor of the hoist 3 rises to a preset threshold and cooling is required, the airbag 38, which is tightly fitted to the motor housing and made of high-temperature resistant flexible material, is filled with a heat-expanding medium such as air or nitrogen. As the motor temperature rises, the medium expands, causing the overall volume of the airbag 38 to expand and deform. This deformation is directly converted into the linear displacement of the top block 39. The top block 39 moves towards the button switch 41 and triggers a pressing action, which connects the circuit of the button switch 41, thereby driving the electric atomizing nozzle 42 to start and atomize the water collected in the water collection box 37 and spray it onto the motor surface to achieve the cooling operation of the motor. When the motor temperature drops to a reasonable range, the medium inside the airbag 38 cools and contracts, the airbag 38 retracts and resets, causing the top block 39 to disengage from the button switch 41. The button switch 41 then resets and de-energizes, and the electric atomizing nozzle 42 stops spraying. The entire cooling control system automatically executes the start and stop actions according to the temperature change of the motor itself, without manual intervention, to achieve temperature adaptive closed-loop cooling control.

[0042] The method for constructing a suspended platform for high-altitude operations according to the present invention includes the following steps: Step 1: Equipment installation and inspection: Suspend the basket 1 at the working position, pass the steel rope 2 through the processing box 6 and the rope inlet 5 of the hoist 3, and confirm that the upper sponge 8 is in the initial compressed state, the stop bar 15 is inserted into the stop groove 14, the limit bar 28 is inserted into the slot 29 and the second spring 27 is in the stretched state.

[0043] Step 2: Water and dust removal operation: Start the hoist 3, and the sponge 8 below absorbs and removes the moisture and impurities on the surface of the steel rope 2. The steel rope 2 passes through the drying tank 17 and drives the blades 19 to rotate through the guide wheel 23. At the same time, the air inlet pipe 21 collects the heat from the motor and sends it into the drying tank 17 to perform secondary hot air drying on the steel rope 2.

[0044] Step 3: Automatic replacement and squeezing of saturated sponge: After saturation, sponge 8 is sucked into collection box 7 by magnet 16, triggering limit rod 28 to disengage from slot 29. Spring 27 drives bent rod 26 to descend, sealing plate 31 falls first to seal treatment box 6 and collection box 7. Bend rod 26 drives pressure plate 30 to squeeze sponge 8, squeezing water into collection box 37 through drain pipe 43. At the same time, sponge 8 above falls back to its original position and expands, automatically taking over the water absorption work.

[0045] Step 4: Motor temperature adaptive cooling: When the motor temperature rises to the preset threshold, the airbag 38 expands due to heat, driving the top block 39 to trigger the button switch 41. The electric atomizing nozzle 42 atomizes the water in the water collection box 37 and sprays it onto the motor surface to cool it down. After the temperature drops, the airbag 38 contracts and resets, and the electric atomizing nozzle 42 stops spraying.

[0046] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method for constructing a suspended platform for high-altitude operations with an overload detection mechanism, relating to the suspended platform for high-altitude operations with an overload detection mechanism as described in any one of claims 1-9, comprising the following steps: Step 1: Suspend the basket (1) at the work position, pass the steel rope (2) through the rope inlet (5) of the processing box (6) and the hoist (3), and confirm that the sponge (8) above is in the initial compression state, the stop bar (15) is inserted into the stop groove (14), the limit bar (28) is inserted into the slot (29) and the second spring (27) is in the tension state. Step 2: Start the hoist (3), the sponge (8) below absorbs and removes the moisture and impurities on the surface of the steel rope (2), the steel rope (2) passes through the drying tank (17), and the guide wheel (23) drives the blade (19) to rotate. At the same time, the air inlet pipe (21) collects the heat of the motor and sends it into the drying tank (17) to dry the steel rope (2) with hot air for a second time. Step 3: The saturated sponge (8) is sucked into the collection box (7) by the magnet (16), and the limit rod (28) is triggered to disengage from the slot (29). The second spring (27) drives the bent rod (26) to descend. The sealing plate (31) falls first to seal the treatment box (6) and the collection box (7). The bent rod (26) drives the pressure plate (30) to squeeze the sponge (8) and squeeze the water into the water collection box (37) through the drain pipe (43). At the same time, the upper sponge (8) falls back to its original position and expands, automatically taking over the water absorption work. Step 4: When the motor temperature rises to the preset threshold, the airbag (38) expands due to heat, driving the top block (39) to trigger the button switch (41). The electric atomizing nozzle (42) atomizes the water in the water collection box (37) and sprays it onto the motor surface to cool it down. After the temperature drops, the airbag (38) contracts and resets, and the electric atomizing nozzle (42) stops spraying.
