[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figures 1-7 As shown, the present invention provides a technical solution: a suspended basket steel pipe frame combined operating platform, including a suspended basket 1, a steel pipe assembly 2 is erected on the upper end of the suspended basket 1, a bearing platform 4 is erected on the upper end of the steel pipe assembly 2, and a reinforcing assembly 6 is provided around the steel pipe assembly 2.

[0020] The reinforcement component 6 includes outer uprights 62 arranged around the support platform 4, and positioning blocks A63 and B64 arranged on the outer surface of the outer uprights 62. A first guardrail 68 and a second guardrail 69 are respectively provided on one side of positioning blocks A63 and B64. A connecting rod 61 is provided at one end of the outer uprights 62, and a right-angle fastener 23 is provided at one end of the connecting rod 61. The connecting rod 61 is connected to the steel pipe assembly 2 through the right-angle fastener 23. A toe plate 7 is provided on one side of the connecting rod 61. Locking buckles 66 are provided on the outer surfaces of both the toe plate 7 and the second guardrail 69, and a dense safety net 65 is fixed inside the locking buckle 66. The positioning blocks A63 and B64 are also equipped with scissor braces 67 on one side. During the entire installation and operation process, the suspended platform 1 is equipped with eight sets of scissor braces, which are set up in pairs. The suspended platform 1 serves to support the steel pipe assembly 2. During the operation, the workers stand on the support platform 4, and the outer uprights 62 provide protection to prevent workers from falling from height. At the same time, the dense safety net 65 further protects the workers. The scissor braces 67, the first guardrail 68, and the second guardrail 69 can enhance the stability of the outer uprights 62. Meanwhile, the toe board 7 can prevent the workers' feet from being stuck in the gap between the support platform 4 and the reinforcement assembly 6.

[0021] The steel pipe assembly 2 includes a horizontal bar 21 and a longitudinal bar 22 erected on the upper end of the suspended platform 1. Multiple sets of horizontal bars 21 and longitudinal bars 22 are provided. Each pair of horizontal bars 21 or longitudinal bars 22 is fixed together by a swivel coupler 24. Combining the suspended platform 1 with the horizontal bars 21 and longitudinal bars 22 can improve the overall stability of the platform.

[0022] The support platform 4 includes scaffold boards 41 laid on the upper ends of the horizontal bars 21 and the longitudinal bars 22. Steel planks 43 are laid on the upper ends of the scaffold boards 41. Through holes A42 are opened on the outer surface of the scaffold boards 41, and through holes B44 are opened on the outer surface of the steel planks 43. Through holes A42 and through holes B44 are set in the same vertical plane. The scaffold boards 41 and steel planks 43 are tied to the horizontal bars 21 and the longitudinal bars 22 by lead wire. Through holes A42 and through holes B44 are opposite to the suspended basket 1.

[0023] Side panels 11 are provided on both sides of the suspended platform 1. A through hole 12 is provided at the upper end of the side panel 11. A laser rangefinder 9 is provided on the upper surface of the side panel 11. The laser rangefinder 9 and the through hole 12 are in the same vertical plane as the through holes A42 and B44. A steel wire rope is threaded through the through hole 12. One end of the steel wire rope passes through the through holes A42 and B44 and is connected to the top structural beam. The steel wire rope will also pass through the hoist, which provides power to the whole structure. When the hoist is started, it lifts the entire suspended platform 1 by traction. At the same time, a reflector is installed on the bottom surface of the top structural beam. The laser rangefinder 9 corresponds to the reflector, so the height between the suspended platform 1 and the ground can be measured and calculated by the laser rangefinder 9.

[0024] A double-layered net bag 8 is provided on one side of the suspended basket 1, and snap-fit ​​blocks 81 are provided on both sides of the double-layered net bag 8. The double-layered net bag 8 is connected to the suspended basket 1 through the snap-fit ​​blocks 81. The double-layered net bag 8 is located below the horizontal bar 21 and the vertical bar 22.

[0025] The reinforcement component 6 consists of four sets. One set of the reinforcement component 6 has an installation slot in the middle section, and a movable door frame 5 is hinged to the installation slot.

[0026] The laser rangefinder 9 is signal-connected to the controller 3, which is in turn signal-connected to the hoist. The controller 3 includes a screen display module 31, which is signal-connected to a punctuation module 32. The punctuation module 32 is signal-connected to a height display module 33, which is signal-connected to an error correction module 34. During operation, before the suspended platform 1 is raised, the laser rangefinder 9 is activated to measure the distance between the eight suspended platforms 1 and the top structural beam. The distance is checked for consistency to prevent errors due to uneven thickness of the top structural beam. If errors exist, the error correction module 34 corrects them to ensure the distance between the eight suspended platforms 1 and the top structural beam is consistent. The structural beams are spaced at the same distance. The overall picture is displayed on the monitor using the screen display module 31. The platform is divided into eight areas according to the eight sets of suspended baskets 1, and the marking module 32 marks these eight areas for easy viewing by the staff. As the suspended baskets 1 rise, the height of the eight sets of suspended baskets 1 above the ground can be seen in real time. If the heights of the eight sets of suspended baskets 1 are the same, it means that the overall lifting speed of the platform is consistent and there will be no tilting. If the heights of the eight sets of suspended baskets 1 are inconsistent, it means that the overall lifting speed of the platform is inconsistent and there is a problem of uneven heights in the eight areas, which will affect the overall stability of the platform and remind the staff to adjust the corresponding hoists in time.

[0027] Using a uniform ground elevation as the zero point of height, let the elevation of the measuring surface of the reflector corresponding to the i-th group of suspended baskets be . The distance from the laser rangefinder 9 to the reflector is... The vertical installation compensation amount from the sensor measurement reference point to the required suspended platform height reference point is: Then the height of the i-th group of suspended platform reference points above the ground Determined according to the following formula: ; When it is necessary to display the ground clearance of the working surface of the support platform 4, the fixed vertical distance from the reference point of the suspended platform height to the working surface of the support platform 4 is used as the platform compensation amount. The corresponding working surface height above the ground. Determined according to the following formula: ; If the eight reflectors are measured to be at the same elevation, then the eight The same value can be used. If the thickness of the top structural beam, the bottom elevation, or the installation position of the reflector are different, then the values ​​for each reflector should be recorded separately. This avoids directly comparing the original distance measurement values. This could lead to a misjudgment.

[0028] When it is only necessary to determine whether the relative lifting of the eight groups of suspended platforms is consistent, the initial distance change can also be used. Let the initial measured distance of the i-th group of suspended platforms before lifting be . The current measured distance is The lifting amount of the basket relative to its initial position is... for: ; In the upward ranging relationship of this embodiment, when the basket 1 moves upward, the distance between it and the top reflector decreases. Therefore, the initial distance minus the current distance gives the upward lifting amount. If the data output direction of the sensor is defined in the opposite way, the controller 3 adjusts the sign according to the sensor calibration direction.

[0029] The top structural beam may have thickness differences and bottom elevation differences, and the installation positions of the eight laser ranging sensors 9 may also have fixed differences; therefore, it is not possible to require the eight original ranging values ​​to be naturally the same before lifting. The error correction module 34 establishes initial compensation values ​​for the eight ranging channels respectively, so that the corrected equivalent height data is at a unified comparison benchmark.

[0030] When the platform is in a known level state or when the eight groups of suspended platforms are located at the same measured reference height, read the initial converted height of the i-th group of suspended platforms. And select a unified target reference height. The initial compensation value of the i-th ranging channel Determined according to the following formula; ; During operation, the corrected height of the i-th group of suspended platforms Determined according to the following formula: ; Error correction module 34 stores the values ​​of each of the eight channels. The error correction here refers to zero-point compensation of the measurement data so that the eight suspended platforms display the same equivalent height when they are at the same actual height, without changing the physical distance between the suspended platform and the top structural beam.

[0031] If the exact elevation of the eight reflectors is known Then they can directly adopt their respective methods. Perform height conversion and To compensate for sensor installation errors, if the absolute elevation cannot be obtained temporarily, a relative zero point can be established when the eight suspended platforms are at the same horizontal reference, so as to compare whether the subsequent lifting amount is consistent.

[0032] The controller 3 is connected to eight sets of laser rangefinders 9. The screen display module 31 establishes a display screen corresponding to the plane shape of the platform. The marking module 32 divides the platform into eight support areas according to the actual installation positions of the eight sets of suspended baskets 1, and sets corresponding markings in each support area.

[0033] The height display module 33 displays the original distance measurement value, corrected height, and height deviation relative to other suspended baskets for each group of suspended baskets 1 in the corresponding area. The staff can determine the specific suspended basket and corresponding hoist that caused the height deviation based on the positional relationship of the eight areas in the screen.

[0034] Average corrected height of eight suspended platforms The regional height deviation of the i-th group of suspended baskets can be determined by the average of eight corrected heights. The difference between the corrected height of the suspended platform and the average corrected height: ; ; A positive value indicates that the i-th group of suspended baskets is in a leading position relative to the average height. A negative value indicates that the i-th group of suspended platforms is lagging behind the average height. The deviation of each suspended platform from the average height is used to quickly locate abnormal areas.

[0035] The eight suspended platforms are arranged in pairs, allowing the overall tilt direction of the platform to be determined by the corrected heights of the platforms on opposite sides. For example, the average corrected heights of the platforms on the first side are taken to obtain the height of the first side, and the average corrected heights of the platforms on the opposite second side are taken to obtain the height of the second side. The difference between the average heights on both sides reflects the elevation difference of the platform along that direction. Let L be the horizontal distance between the two sets of opposing suspended platform support areas, and ΔH be the corrected height difference on both sides. Then, the tilt angle θ of the platform in the corresponding direction can be calculated using the following formula: ; Controller 3 can also directly use the height difference ΔH as the judgment parameter. When the height difference between the two sides is within the allowable range, the platform is considered to be synchronized in that direction. When the height difference exceeds the allowable range and persists, the screen display module 31 highlights the leading and lagging areas, prompting the staff to adjust the corresponding hoist.

[0036] When the height deviation of a single suspended platform is large while the height of other suspended platforms on the same side is normal, it may cause local support points to be ahead or behind. In this case, the steel pipe assembly 2 may immediately show obvious tilting of the platform surface due to its own rigidity. However, additional forces may still be formed near the corresponding support point. Therefore, it is still necessary to deal with the height deviation of the eight areas.

[0037] Controller 3 continuously acquires eight corrected heights according to a predetermined sampling period, and the actual lifting speed of the i-th group of suspended baskets between two adjacent sampling times. It can be determined based on the corrected height change and the sampling time interval: ; When the current height deviation of the eight suspended platforms is within the allowable range, and the difference in lifting speed is also within the allowable range, it indicates that the eight suspended platforms are lifting synchronously. When the corrected height of a certain suspended platform is continuously higher than the average corrected height, the suspended platform is in a state of continuous advance, and the controller 3 outputs a speed reduction or pause prompt to the corresponding hoist. When the corrected height of a certain suspended platform is continuously lower than the average corrected height, the suspended platform is in a state of continuous lag. The controller 3 outputs a check or adjustment prompt to the corresponding hoist. After the staff confirms that the corresponding suspended platform, wire rope and hoist are operating normally, the suspended platform can be made to follow at a low speed, or the lifting speed of the leading suspended platform can be reduced.

[0038] To avoid frequent adjustments caused by instantaneous fluctuations in the sensor, controller 3 can require the height deviation to exceed the allowable range for multiple consecutive sampling cycles before outputting an adjustment prompt. The specific sampling cycle, number of consecutive cycles, and allowable height difference are determined based on the platform span, the allowable deformation of the steel pipe assembly 2, and the construction plan.

[0039] This invention also provides a technical solution: a construction method for a combined operating platform with a suspended steel pipe frame, comprising the following steps: Step S1, Installation and unified positioning of the suspended platform: Determine the corresponding suspension point positions of the eight sets of suspended baskets 1 on the top structural beam, install steel wire ropes, and put rubber hoses on the acute angle or obstacle positions. Pass the steel wire ropes through the perforations 12 on the side plate 11 of the suspended basket 1 and cooperate with the hoist so that the eight sets of suspended baskets 1 are suspended from the top structural beam respectively.

[0040] Install reflectors corresponding to each laser rangefinder 9 on the bottom surface of the top structural beam, record the elevation of the measuring surface of each reflector, start the laser rangefinder 9, and establish the initial compensation value of each rangefinder channel when the eight sets of suspended baskets 1 are in the known reference position.

[0041] The eight sets of suspended platforms 1 are raised to the construction area at low speed. The controller 3 displays the corrected height of the eight sets of suspended platforms 1 in real time. When the height of a certain suspended platform is ahead, the corresponding hoist is lowered or paused. When the height of a certain suspended platform is behind, it is followed up at low speed after confirming that it is operating normally, so that the eight sets of suspended platforms 1 reach the support elevation required for erection.

[0042] Step S2, Frame and support platform erection: Horizontal bars 21 and vertical bars 22 are erected on the eight sets of suspended baskets 1. The distance between adjacent joints is not less than 500mm, the overlap length is not less than 1m, and three swivel couplers 24 are used for fixation. The intersection of the horizontal bar 21 and the vertical bar 22 is fixed by right-angle couplers 23. The distance from the end against the wall to the wall decoration surface is not greater than 100mm.

[0043] Scissor bracing 67 is installed below the horizontal bar 21 and the longitudinal bar 22. Scissor bracing 67 is installed every 4.5m. The joint is lapped, with an overlap length of not less than 1m, and is fixed by two swivel fasteners 24.

[0044] Scaffold boards 41 with a specification of 3000mm×200mm×50mm are laid on the steel pipe assembly 2. The overhang length of the scaffold boards 41 is no more than 200mm. The scaffold boards 41 are tied together by double strands of No.12 to No.14 wire. Each scaffold board 41 has no less than four tying points. The scaffold boards 41 at the corners are reliably connected to the steel pipe assembly 2 to prevent slippage.

[0045] Steel planks 43 are laid on the surface of the scaffold plank 41, and the through holes A42 and B44 are aligned with the steel wire rope and distance measuring channel of the corresponding hanging basket 1.

[0046] Step S3, Protection and Connection: Connecting rods 61 and external uprights 62 are installed around the steel pipe assembly 2. The connecting rods 61 are connected to the horizontal bar 21 or the longitudinal bar 22 via right-angle fasteners 23.

[0047] Positioning blocks A63 and B64 are installed on the outer uprights 62, and the first guardrail 68 and the second guardrail 69 are installed through the positioning blocks A63 and B64. Scissor bracing 67 is installed between the outer uprights 62.

[0048] A dense safety net 65 is installed on the inner side of the outer upright 62, and the dense safety net 65 is fixed to the corresponding positions of the second guardrail 69 and the toe board 7 by locking buckle 66. The toe board 7 is installed around the bearing platform 4, and a double-layer net bag 8 is installed under the steel pipe assembly 2 by snap-fit ​​block 81.

[0049] Install the movable door frame 5 at the reserved installation slot. After the platform is erected, check the installation status of the fasteners, scaffold boards, guardrails, dense safety net, toe board and double-layer net bag.

[0050] Step S4, Platform leveling and usage monitoring: After the platform is erected, the corrected height of the eight suspended platforms 1 is read again. If the height of the eight areas is within the allowable range, the hoist is locked and put into use. If a certain area is ahead or behind, the corresponding hoist is adjusted at low speed under the condition that there are no personnel or moving loads on the platform.

[0051] During the adjustment process, the height changes of the eight areas are continuously observed. After each adjustment, the platform is allowed to stabilize before the next adjustment is made. Once the platform reaches the working height, the lifting mechanism is kept in motion, and the position of the eight support points is monitored by the laser rangefinder 9.

[0052] When the detection value of a single laser rangefinder 9 suddenly changes, while the height of other suspended platforms remains stable, first check whether the ranging optical path is blocked by wire ropes, construction personnel, or other objects, and check whether the reflector is contaminated or loose. Do not adjust the hoisting machine based solely on the abnormal ranging point until the abnormal ranging point returns to stability.

[0053] When the height of a certain suspended platform continues to lag behind, stop the overall lifting and check whether the corresponding hoist, wire rope, safety lock and suspended platform are restricted by obstacles. Only after confirming that there is no obstruction can low-speed follow-up be carried out.

[0054] When multiple adjacent suspended platforms exhibit height deviations in the same direction, check the operating status of the hoist on that side and the installation status of the reflector on the top structural beam. When a continuous height difference forms between the suspended platforms on opposite sides, suspend the overall hoisting and adjust the platform in the order of first suppressing the leading side and then allowing the lagging side to follow at a low speed.

[0055] When the platform has entered the working state and a change in the position of the suspended platform is detected, the platform operation is stopped, personnel and materials in the corresponding area are evacuated, and a decision is made on whether to re-level after checking the connection status of the suspended platform, wire rope, fasteners and steel pipe assembly 2.

[0056] The display module 31 displays the platform's planar outline, and the marking module 32 generates eight support point markers according to the actual positions of the eight sets of suspended baskets 1. Each support point marker displays the original distance, corrected height, height deviation, and lifting status.

[0057] The height display module 33 can use colors to distinguish different states. A normal state is displayed when the height deviation is within the allowable range; a warning state is displayed when the height deviation is close to the allowable boundary; and an adjustment state is displayed when the height deviation exceeds the allowable boundary and persists. Colors are only for auxiliary display; actual control judgment is based on numerical values ​​and duration.

[0058] Error correction module 34 sets the calibration interface. When all eight suspended platforms are at the same known height, the operator performs zero-point calibration, and the module saves the initial compensation values ​​for all eight channels. Calibration should be performed again after reinstalling the sensors, reflectors, or side plates.

[0059] This implementation method is applicable to construction areas such as the atrium roof, high-ceiling ceiling, bottom of high-altitude corridors, and curtain wall decoration of high-rise public buildings. It is especially suitable for indoor high spaces where passage is required on the ground floor, the load-bearing capacity of the basement roof is limited, the construction area spans a large area, and large lifting equipment is difficult to access.

[0060] The platform can be applied to construction areas with an erection height of 10m to 30m and a construction load not exceeding 3kN / m². It can also be used for processes such as ceiling joist installation, surface finishing, and curtain wall component fixing. The above-mentioned height and load are within the scope of engineering implementation. Specific projects should be specifically calculated based on the load-bearing capacity of the top structural beam, the rated load of the suspended platform, the allowable tensile strength of the wire rope, the span of the steel pipe, and the connection capacity of the fasteners.

[0061] One selection method uses the ZLP630 type suspended platform, with a rated load capacity of 630kg per platform. The working wire rope is a 4×31SW+NF-8.3 type wire rope, and the minimum breaking strength of the wire rope is not less than 53kN. The eight sets of suspended platforms 1 serve as support points for the steel pipe assembly 2, and the platform design and construction load is controlled within 3kN / m².

[0062] Steel pipe assembly 2 can form an operating area with a length of 16m and a width of 15m. Both the longitudinal and transverse spacing can be set to 1.5m. The platform safety level can be considered as Level II, and the structural importance coefficient can be taken as 1. The above data is used to illustrate one engineering configuration and does not constitute an exclusion of other dimensions after stress verification.

[0063] Before construction, a special construction plan was prepared based on the building structure, the location of the hoisting points, the platform plane dimensions and the construction load. The plan clearly specifies the location of the eight sets of suspended baskets 1, the method of fixing the wire ropes, the arrangement of the members of the steel pipe assembly 2, the load limit of the platform, the correspondence between the laser rangefinder sensor 9 and the reflector, and the stop measures under abnormal conditions.

[0064] Upon arrival, steel pipes should be inspected for product qualification certificates, specifications, wall thickness, bending, and rust condition. When using φ48×2.75mm steel pipes, the actual measured wall thickness should not be less than 2.75mm, and the surface rust depth should not exceed 0.5mm. Steel pipes with flattening, cracks, obvious bending, or severe rust should not be used for steel pipe assembly 2.

[0065] After the right-angle fasteners 23 and swivel fasteners 24 arrive on site, inspect their appearance, bolts, cover plates, and rotating parts, and randomly check the bolt tightening torque. The bolt tightening torque after fastener installation can be controlled between 40 N·m and 65 N·m to balance connection reliability and fastener integrity.

[0066] The wire rope should have a corresponding minimum breaking strength report, and its surface should be free of broken strands, severe wear, flattening, and corrosion. Safety locks should be within their caliber and have corresponding testing data. Scaffold boards 41 and steel planks 43 should be intact and straight; any broken, severely deformed, or load-bearing components should be replaced.

[0067] Before installation, the laser rangefinder sensor 9 should undergo a power-on check and zero-point calibration. The mounting surface of the reflector should be flat and clean. The eight rangefinder channels should be numbered and correspond one-to-one with the eight sets of suspended platforms 1, the eight areas on the display screen, and the corresponding hoists.

[0068] The project's technical lead provided technical instructions to the suspended platform installation personnel, scaffold erection personnel, and distance control personnel. The instructions included the structural installation sequence, member parameters, suspended platform load limits, distance calibration methods, lifting and adjustment sequence, and emergency stop requirements.

[0069] Working principle: The load on the bearing platform 4 is first distributed to the horizontal bar 21 and the longitudinal bar 22 through the scaffold boards 41 and steel planks 43, and then transferred to the eight suspended baskets 1 by the steel pipe assembly 2, and then transferred to the top structural beam through the steel wire ropes of each suspended basket 1, thus forming a complete vertical load transfer path; at the same time, the outer uprights 62, the first guardrail 68, the second guardrail 69 and the scissor bracing 67 together form a perimeter reinforcement frame, the dense safety net 65 is used to restrict personnel and materials from falling from the side of the platform, the toe board 7 is used to close the low gap at the edge of the working surface, and the double-layer net bag 8 provides bottom protection for the steel pipe assembly 2; during the lifting and lowering of the eight suspended baskets 1, the laser rangefinder 9 installed on each suspended basket 1 emits a rangefinder beam to the corresponding reflector on the top structural beam, and obtains the distance between each suspended basket 1 and the corresponding reflector based on the return signal, and then calculates the ground clearance of each suspended basket 1 by combining the elevation of the corresponding reflector and the sensor installation compensation; in order to eliminate the thickness difference of the top structural beam, The impact of reflector elevation difference and laser rangefinder sensor 9 installation difference on height comparison results is investigated. When the eight suspended platforms 1 are in a known baseline state, compensation values ​​are established for each ranging channel. During operation, the corresponding compensation values ​​are used to correct the ground clearance of each suspended platform 1, ensuring the height data of the eight suspended platforms 1 are at a unified comparison benchmark. Based on this, the deviation of each support area from the average height of the eight suspended platforms 1 is determined according to the corrected height of each suspended platform 1. The average height of the suspended platforms 1 on opposite sides is compared. When a support area is continuously ahead or behind, the hoist corresponding to that support area is identified as the adjustment target. When a continuous height difference is formed between opposite sides, the tilt direction of the platform is further determined. Subsequently, the hoist corresponding to the ahead suspended platform 1 is decelerated or paused. After confirming that the lagging suspended platform 1 is not jammed and its operation is normal, the hoist corresponding to the lagging suspended platform 1 is made to follow at low speed. After each adjustment, the height of the eight suspended platforms 1 is re-detected until the height difference between each support area returns to the allowable range.
