Description

Technical Field

[0001] This invention relates to the field of basket leveling technology, and in particular to a leveling device and method for a manned work basket. Background Technology

[0002] In manned high-altitude operations such as building exterior decoration, high-altitude equipment maintenance, and bridge maintenance, the manned work basket is the core load-bearing equipment. Its operational stability and levelness are directly related to the life safety of the operators and the quality of construction. Therefore, the leveling device, as a key safety component of the basket, is mainly used to counteract the tilt caused by factors such as operator movement, material stacking deviation, and wind disturbance during the operation, ensuring that the basket is always in a safe level working posture.

[0003] Currently, existing leveling technologies for manned operation baskets mainly fall into two categories: one is the traditional passive leveling, which achieves initial leveling by manually adjusting the tension of the wire rope and adding fixed counterweights; the other is a simple active leveling, which uses tilt sensors to detect the tilt angle of the basket and corrects the tilt by controlling the lifting speed of the hoisting equipment on one side or the length of the wire rope. These technologies have been applied to some extent in low-height, low-complexity operation scenarios. However, in high-risk, dynamic operation scenarios, existing technologies are mostly designed for leveling mechanisms that target large-angle tilts of the basket. They lack effective monitoring and adjustment methods for small-angle tilts caused by operator movement. Although small-angle tilts do not affect operations in the short term, they can cause a continuous shift in the basket's center of gravity, which can easily lead to psychological stress for operators, a poor working environment, and reduced construction efficiency. On the other hand, it can cause continuous overload on one side of the wire rope, accelerating wire rope fatigue and aging. Furthermore, as the operator moves further, the tilt angle can easily accumulate and amplify, eventually exceeding the safety threshold.

[0004] Furthermore, existing passive and active leveling technologies typically employ a single-sided lifting correction method. When the bucket basket tilt angle exceeds the threshold, passive leveling exhibits lag, making it difficult for the bucket basket to quickly return to a safe posture. Active leveling technology requires reducing the safe threshold for bucket basket tilt, which necessitates frequent control of the winch equipment. This increases the wear, fatigue, and breakage of core load-bearing components such as wire ropes and winches, thereby reducing the overall service life of the bucket basket.

[0005] Therefore, there is an urgent need to provide a leveling device and leveling method for manned work baskets that can improve the stability of operators during construction and extend the service life of the basket. Summary of the Invention

[0006] Therefore, it is necessary to provide a leveling device and leveling method for a manned work basket, in order to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a leveling device for a manned work basket, comprising: a pallet, with a guardrail installed on the upper end of the pallet.

[0008] The leveling device of the manned work basket also includes a pressure regulating unit, which is set on the support plate and used for dynamic adjustment of the basket under small-angle tilt. The pressure regulating unit includes a force-bearing part set on the upper end of the support plate and a counterweight regulating part set in the support plate.

[0009] The force-bearing part includes multiple force-bearing plates that are evenly distributed on the support plate. Multiple pressure sensors that are evenly distributed are installed at the lower end of the force-bearing plates. The pressure sensors are fixedly connected to the support plate.

[0010] The counterweight adjustment unit includes a sliding cavity opened in the tray, a movable component installed in the sliding cavity, and multiple counterweights connected to the movable component. A pressure sensor senses the force on the force plate and controls the movable component to change the position of the multiple counterweights, thereby dynamically adjusting the stability of the basket's center of gravity.

[0011] The leveling device for the manned work basket also includes a tilt adjustment unit, which includes a tilt sensor installed in the middle of the lower end of the pallet, and traction parts installed on both the left and right sides of the upper end of the guardrail, with two winding parts connected to the traction parts.

[0012] When the basket is tilted at a small angle, the force-bearing part controls the counterweight adjustment part to dynamically adjust the center of gravity of the basket; when the tilt angle sensor detects that the tilt angle exceeds the threshold, the tilt angle sensor controls the corresponding winding part to wind up the corresponding traction part, driving the basket to automatically return to within the allowable tilt angle range.

[0013] Preferably, the force-bearing part further includes a mounting groove formed on the upper end of the support plate, and both the force-bearing plate and the pressure sensor are located in the mounting groove, with the upper end of the force-bearing plate and the upper end of the mounting groove at the same height.

[0014] Preferably, the moving component includes two sliding rails symmetrically installed on the front and rear walls of the sliding cavity, and multiple electric sliders are slidably connected to each of the two sliding rails. Two electric sliders at corresponding front and rear positions are fixedly connected to corresponding counterweights.

[0015] Preferably, the traction unit includes a connecting rod disposed above the guardrail, with two sliding frames symmetrically installed at the lower end of the connecting rod, and a traction column disposed inside the sliding frame, the lower end of the traction column being fixedly connected to the guardrail.

[0016] Preferably, the traction unit further includes two sliding through holes respectively opened on the two traction columns, and a support column is slidably connected in the sliding through holes. The two ends of the support column are simultaneously fixedly connected to the inner surface of the sliding frame.

[0017] Preferably, the winding section includes a support platform symmetrically mounted on the connecting rod, a winding motor is mounted on the upper end of the support platform, a winding roller is mounted on the output shaft of the winding motor, the winding roller is connected to the support platform through a rolling frame, a traction steel rope is wound on the winding roller, one end of the traction steel rope slides through the connecting rod and is fixedly connected to the upper end of the traction column located in the corresponding sliding frame.

[0018] Preferably, the traction steel rope is provided with rotating rollers on both the left and right sides at the upper end of the connecting rod, and the two rotating rollers are fixedly connected to the connecting rod by roller frame.

[0019] Preferably, the leveling device for the manned work basket also includes two winches for lifting the basket as a whole.

[0020] In addition, the present invention also provides a leveling method for a manned work basket, which specifically includes the following steps: S1: The suspension beam and bracket are fixed to the building load-bearing structure using embedded parts or special clamps, and then the wire rope tensioning device is installed to initially adjust the wire rope tension to be uniform.

[0021] S2: Then connect the basket to the traction steel rope and perform leveling and no-load testing.

[0022] S3: After the no-load test is completed, the operator enters the bucket with tools, places the material evenly in the middle of the basket, and the operator remotely or on-site controls the hoisting equipment to raise the bucket to the working surface for work.

[0023] S4: During operation, when the operator walks inside the basket, the basket's center of gravity changes and tilts at a small angle, the force plate transmits pressure to the pressure sensor. The pressure sensor controls the moving parts to change the position of multiple counterweights, thereby ensuring the stability of the basket's center of gravity.

[0024] S5: When the tilt sensor detects that the tilt angle exceeds the threshold, the tilt sensor controls the corresponding winding part to wind up the corresponding traction part, driving the basket to automatically return to within the allowable tilt angle range.

[0025] S6: After the work is completed, the operator uses remote or on-site control of the winch to lower the bucket basket to the ground, and the work is finished.

[0026] In summary, the present invention has the following beneficial effects: 1. The pressure adjustment unit and tilt adjustment unit used in the present invention work together to achieve the function of a dual protection mechanism of "small angle dynamic leveling + large angle automatic reset", which effectively avoids the cumulative increase of the tilt angle of the bucket basket, avoids the lag of adjustment, reduces the risk of personnel falling and bucket basket tipping over, improves the construction safety of operators, and also avoids the phenomenon of uneven stress on one side of the wire rope, thus improving the service life of the bucket basket.

[0027] 2. The pressure adjustment unit used in this invention employs uniformly distributed force plates and pressure sensors, resulting in a fast response speed. It can dynamically adjust the position of multiple counterweights according to the operator's walking trajectory, achieving real-time stability of the basket's center of gravity and avoiding the lag of traditional leveling methods. It also avoids the superposition of tilt angles caused by the operator moving to the side, thus balancing the stability and comfort of using the basket.

[0028] 3. The tilt angle adjustment unit used in this invention, due to the presence of a pressure adjustment unit, can appropriately increase the safety threshold. When the tilt angle of the bucket basket exceeds the set threshold, the winding part adjusts the angle of the bucket basket through the traction part, effectively reducing the use of traction steel rope and wire rope, thereby reducing the fatigue of traction steel rope and wire rope, reducing abnormal losses in the connection between wire rope and winch equipment, and improving the service life of the bucket basket.

Detailed Implementation

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] See Figures 1-3 A leveling device for a manned work basket includes a support plate 1, with a guardrail 2 installed on the upper end of the support plate 1. The guardrail 2 can be fixedly connected to the support plate 1 by bolts or welding. The leveling device for the manned work basket also includes two winches 5 for lifting the basket as a whole. The two winches 5 are respectively installed on both sides of the guardrail 2. The winches 5 include a motor, a reducer, a drum, a braking system, etc. (this is prior art). A control system is also installed on the guardrail 2 (this is prior art and is not shown in the figure).

[0039] In practice, the suspended beams and support structures required for construction are fixed to the building's load-bearing structure using embedded parts or special clamps. Then, the wire rope tensioning device is installed. Subsequently, the wire rope is connected to the two winches 5, the fixed pulleys on the suspended beams, and the existing counterweights. The wire rope tension is initially adjusted to be uniform, thus achieving the connection of the bucket basket.

[0040] See Figure 4 and Figure 5 The leveling device of the manned operation work basket also includes a pressure adjustment unit 3 set on the pallet 1 for dynamic adjustment of the basket under small angle tilt. The pressure adjustment unit 3 includes a force-bearing part 30 set on the upper end of the pallet 1 and a counterweight adjustment part 31 set in the pallet 1.

[0041] See Figure 1 , Figure 4 and Figure 6 The leveling device of the manned work basket also includes a tilt adjustment unit 4. The tilt adjustment unit 4 includes a tilt sensor 40 installed in the middle of the lower end of the pallet 1. A traction part 41 is installed on both the left and right sides of the upper end of the guardrail 2. Two winding parts 42 are connected to the traction part 41.

[0042] Before construction, the tilt sensor 40 is connected to the control system's electrical signal. The bucket basket is initially leveled by adjusting the steel wire rope based on the tilt sensor 40's display. Then, a no-load test is performed on the bucket basket. After the no-load test, the operator enters the bucket basket with tools, and the material is evenly placed in the center of the basket. The operator remotely or locally controls the hoisting device 5 to raise the bucket basket to the working surface for operation. During operation, when the bucket basket tilts at a small angle (i.e., the tilt angle does not exceed the threshold set by the tilt sensor 40), the force-bearing part 30 can dynamically adjust the counterweight adjustment part 31 according to the operator's position, leveling the bucket basket to a state that does not affect the operator's work and preventing the bucket basket from continuously tilting. This design avoids lag in adjustment and allows for leveling of the basket even when the tilt angle is small, preventing a gradual increase in the tilt angle and effectively preventing uneven stress on the wire rope on the tilted side. This ensures the safety of operators and extends the service life of the basket. When the tilt angle detected by the tilt sensor 40 exceeds the threshold, the tilt sensor 40 controls the corresponding winding part 42 to wind up the corresponding traction part 41, causing the basket to automatically return to within the allowable tilt angle range. Then, the force-bearing part 30 controls the counterweight adjustment part 31 to dynamically adjust the basket, returning it to a state that does not affect the operator's work, ensuring the stability of the basket and the comfort of the operator.

[0043] See Figure 4 and Figure 5 The force-bearing part 30 includes a plurality of force-bearing plates 300 evenly distributed on the support plate 1. A plurality of pressure sensors 301 evenly distributed are installed at the lower end of the force-bearing plate 300. The pressure sensors 301 are fixedly connected to the support plate 1. Before construction, the pressure sensors 301 are connected to the control system electrical signal.

[0044] See Figure 4 and Figure 5 The force-bearing part 30 also includes a mounting groove 302 formed on the upper end of the support plate 1. The force-bearing plate 300 and the pressure sensor 301 are both located in the mounting groove 302, and the upper end of the force-bearing plate 300 is at the same height as the upper end of the mounting groove 302.

[0045] See Figure 4 and Figure 5 The counterweight adjustment unit 31 includes a sliding cavity 310 opened in the tray 1. A movable component is installed in the sliding cavity 310. Multiple counterweights 313 are connected to the movable component. The counterweights 313 are existing counterweight blocks. The counterweights 313 can be made of metal or non-metal materials with high density. The pressure sensor 301 senses the force on the force plate 300 and controls the movable component to change the position of the multiple counterweights 313, dynamically adjusting the stability of the basket's center of gravity.

[0046] See Figure 4 and Figure 5The moving component includes two sliding rails 311 symmetrically installed on the front and rear walls of the sliding cavity 310. Multiple electric sliders 312 are slidably connected to each of the two sliding rails 311. Two electric sliders 312 at corresponding front and rear positions are fixedly connected to the corresponding counterweights 313.

[0047] When the tilt angle of the bucket basket does not exceed the threshold set by the tilt sensor 40, the operator walks on multiple force plates 300 on the pallet 1. Each force plate 300 transmits the pressure received to the pressure sensor 301 at the corresponding position. After receiving the force, the pressure sensor 301 feeds back to the control system through an electrical signal. The control system processes the data and controls the corresponding electric slider 312 to move in the opposite direction of the operator's movement on the sliding rail 311 through the electrical signal. The moving electric slider 312 drives the corresponding number of counterweights 313 to move to the corresponding positions, ensuring that the overall center of gravity of the bucket basket remains stable. In addition, the pressure sensor 301 and the control system have a fast response speed and can dynamically level the bucket basket according to the position of the operator. This avoids the phenomenon of the bucket basket tilting angle increasing as the operator moves to the side of the bucket basket. At the same time, it can avoid the phenomenon of fatigue acceleration caused by the continuous large force on one side of the wire rope, and also avoid the phenomenon of abnormal connection between the wire rope and the winch 5, thus improving the service life of the bucket basket.

[0048] See Figure 1 and Figures 4-6 The traction unit 41 includes a connecting rod 410 disposed above the guardrail 2. Two sliding frames 411 are symmetrically installed at the lower end of the connecting rod 410. A traction column 412 is disposed inside the sliding frame 411. The lower end of the traction column 412 is fixedly connected to the guardrail 2. A safety lock (existing equipment) is also installed on the connecting rod 410. When the basket is connected to the wire rope, the wire rope passes through the safety lock.

[0049] See Figure 1 and Figures 4-6The winding section 42 includes a support platform 420 symmetrically mounted on the connecting rod 410. A winding motor 421 is mounted on the upper end of the support platform 420. A winding roller 422 is mounted on the output shaft of the winding motor 421. The winding roller 422 is connected to the support platform 420 through a rolling frame. A traction steel rope 423 is wound on the winding roller 422. One end of the traction steel rope 423 slides through the connecting rod 410 and is fixedly connected to the upper end of the traction column 412 located in the corresponding sliding frame 411. The upper end of the traction column 412 is one end distance away from the connecting rod 410. At the same time, the diameter of the traction column 412 is smaller than the inner diameter of the sliding frame 411. This space allows the traction column 412 to rise and tilt slightly, which facilitates the angle adjustment of the corner of the basket at the corresponding position of the traction column 412. Furthermore, the traction column 412 is set at the four corners of the guardrail 2, which effectively increases the connection points between the traction steel rope 423 and the basket, which not only improves the stability of the basket hanging but also increases the adjustable range of the basket tilt angle.

[0050] See Figure 4 and Figure 6 The traction steel rope 423 is provided with rotating rollers 415 on both the left and right sides at the upper end of the connecting rod 410. The two rotating rollers 415 are fixedly connected to the connecting rod 410 through roller frames.

[0051] When the tilt angle of the basket exceeds the threshold set by the tilt sensor 40, the tilt sensor 40 feeds back the angle measured in the tilt direction to the control system via an electrical signal. The control system processes the data and controls the corresponding winding motor 421 to start via the electrical signal. The winding motor 421 drives the winding roller 422 to rotate and wind up the traction steel rope 423. The traction steel rope 423 effectively reduces the friction between itself and the connecting rod 410 by rotating the roller 415. The traction steel rope 423 drives the traction column 412 to move within the sliding frame 411. The traction column 412 drives the guardrail 2 and the support plate 1 to move, thereby changing the tilt angle of the basket and restoring it to within the allowable tilt angle range. After leveling the basket by adjusting its small tilt angle, the large tilt angle of the basket is effectively avoided, further ensuring the construction and installation by the operators and ensuring the stability of the basket in use.

[0052] See Figure 1 and Figures 4-6 The traction part 41 also includes two sliding through holes 413 respectively opened on the two traction columns 412. A support column 414 is slidably connected in the sliding through hole 413. Both ends of the support column 414 are fixedly connected to the inner surface of the sliding frame 411.

[0053] In actual operation, the support column 414 cooperates with the sliding through hole 413. When the support column 414 moves to the top of the sliding through hole 413, a rigid connection can be achieved between the sliding frame 411 and the traction column 412, which effectively increases the connection strength between the sliding frame 411 and the traction column 412 and avoids the phenomenon of separation between the sliding frame 411 and the traction column 412 due to the breakage of the traction steel rope 423. When the basket operation encounters bad weather, the four winding motors 421 can work simultaneously to pull the four traction columns 412 towards the connecting rod 410 until the lower end of the sliding frame 411 is in close contact with the guardrail 2, reducing the gap between the sliding frame 411 and the guardrail 2, thereby reducing the conditions for the basket to sway in bad weather and further ensuring the stability of the basket.

[0054] In addition, the present invention also provides a leveling method for a manned work basket, which specifically includes the following steps: S1: The suspension beam and bracket are fixed to the building load-bearing structure using embedded parts or special clamps, and then the wire rope tensioning device is installed to initially adjust the wire rope tension to be uniform.

[0055] S2: Then connect the basket to the traction steel rope 423 and perform leveling and no-load testing.

[0056] S3: After the no-load test is completed, the operator enters the bucket with tools, places the material evenly in the middle of the basket, and the operator remotely or on-site controls the hoisting equipment 5 to raise the bucket to the working surface for work.

[0057] S4: During operation, when the operator walks inside the basket and the basket's center of gravity changes and tilts at a small angle, the force plate 300 transmits pressure to the pressure sensor 301. The pressure sensor 301 controls the moving parts to change the position of multiple counterweights 313, thereby ensuring the stability of the basket's center of gravity.

[0058] S5: When the tilt angle sensor 40 detects that the tilt angle exceeds the threshold, the tilt angle sensor 40 controls the corresponding winding part 42 to wind up the corresponding traction part 41, driving the basket to automatically reset to within the allowable tilt angle range.

[0059] S6: After the work is completed, the operator uses the hoisting device 5 remotely or on-site to lower the bucket basket to the ground, and the work is finished.

S5: When the tilt sensor detects that the tilt angle exceeds the threshold, the tilt sensor controls the corresponding winding part to wind up the corresponding traction part, driving the basket to automatically return to within the allowable tilt angle range. S6: After the work is completed, the operator uses remote or on-site control of the winch to lower the bucket basket to the ground, and the work is finished.
