Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction equipment, and particularly relates to an indoor adjustable building construction high-altitude operation device. BACKGROUND

[0002] In modern building construction, especially in building projects with complex slope roofs or top structures, traditional facade construction methods often rely on scaffolding or suspended equipment, which not only consumes time and effort, but also has many shortcomings in safety and flexibility.

[0003] Traditional full-scaffold erection needs to damage the waterproof layer, and the roof bearing capacity is insufficient, which can easily cause collapse. When the building height exceeds 50 meters, the stability of the scaffold body is significantly reduced, which poses a major safety hazard. The external hanging basket cannot adapt to the inclined boundary of the slope roof, and there is a risk of overturning.

[0004] Existing high-altitude operation equipment is mostly bulky and difficult to operate in indoor narrow spaces, and has poor adaptability to different structures, which cannot meet the needs of rapid deployment and flexible adjustment. The vehicle-mounted lifting platform relies on outdoor site bearing capacity and cannot enter the green belt, underground pipe network area or narrow alley.

[0005] For example, the existing patent: a building facade construction high-altitude operation vehicle (CN202322641390.8), comprising a high-altitude operation vehicle body, a telescopic adjusting frame is arranged on the top of the high-altitude operation vehicle body, an adjusting frame is fixedly arranged on the side of the top of the telescopic adjusting frame, an outer frame is slidably connected to the inner wall of the adjusting frame, an inner frame is slidably connected to the inner wall of the outer frame, a protective fence is fixedly arranged on the top of the inner frame, a motor one is fixedly arranged on the side of the adjusting frame, and a threaded rod one is fixedly sleeved on the output shaft of the motor one. Through the cooperation of the adjusting frame and the outer frame, the motor one drives the threaded rod one to rotate, so that the sliding block in the inner wall of the adjusting frame is driven to slide by the threaded rod one, so that the inner frame and the protective fence are driven to slide by the outer frame through the sliding block. Adjusting is assisted by the limiting block and the limiting groove to stabilize the adjustment of the outer frame, thereby facilitating workers to efficiently perform outer wall construction. The adjusting frame structure of the building facade construction high-altitude operation vehicle is large and fixed in shape, which is not suitable for indoor construction, especially cannot be extended from indoors to outdoors for multi-scene and multi-position operation.

The wheel set 102 is arranged on the bottom side of the frame 101 to drive the frame 101 to move. The hydraulic strut 104 is arranged on the bottom side of the front end of the frame 101 to stably support the frame 101 on the ground.

[0029] Preferably, the frame 101 is further equipped with a hydraulic box 103 and an electromechanical box 105 . The hydraulic box 103 stores hydraulic oil for providing hydraulic power to each hydraulic structure, and the electromechanical box 105 is used to control each electrical structure.

[0030] The frame 101 serves as the main load-bearing structure of the equipment, supporting the installation of the hydraulic box 103, the electromechanical box 105, the wheel set 102 and the hydraulic strut 104, and transferring the load of the working platform to the ground. The wheel set 102 enables the equipment to move indoors and provides stable ground support. The hydraulic box 103 stores hydraulic oil and provides power for the extension and retraction and angle adjustment of the hydraulic strut and support arm through the hydraulic pump. The hydraulic strut 104 is mainly used for stable support from the frame to the ground to prevent the equipment from overturning.

[0031] Preferably, the support arm 2 includes: a bracket 202 , a telescopic hydraulic rod 203 , a multi-section telescopic arm 204 and an angle adjustment rod 205 .

[0032] The bracket 202 is erected on the top of the mobile body 1, that is, the top of the frame 101, and can rotate in the horizontal plane; the tail of the multi-section telescopic arm 204 is hingedly connected to the bracket 202 to realize the vertical rotation of the multi-section telescopic arm, and the head of the multi-section telescopic arm 204 is connected to the working platform 3; and the multi-section telescopic arm 204 completes the telescopic drive of each section through the telescopic hydraulic rod 203.

[0033] One end of the angle adjustment rod 205 is fixed to the top of the mobile body 1, that is, the angle adjustment rod 205 is fixed to the top of the frame 101, and the other end is connected to the node on the multi-section telescopic arm 204 close to the bracket 202, and the multi-section telescopic arm 204 is driven to rotate around the bracket 202 through the extension and retraction of the angle adjustment rod 205.

[0034] Preferably, the tail end of the multi-section telescopic arm 204 is further provided with a supporting arm 2 counterweight block for balancing the weight of the working platform 3 at the head end of the multi-section telescopic arm 204 .

[0035] Preferably, an adaptive stabilizing platform 206 is provided between the head of the multi-section telescopic arm 204 and the working platform 3. The adaptive stabilizing platform 206 is equipped with an inclination sensor, a pressure sensor, and a hydraulic execution module for completing real-time monitoring of the inclination angle and load of the working platform 3 to ensure the stability of the working platform.

[0036] Specifically, the support arm counterweight 201 is used to balance the torque when the support arm 2 is extended to prevent the equipment from overturning due to the shift of the center of gravity. The bracket 202 connects the support arm and the mobile body 1, and is composed of high-strength bearings, rotating joints and locking mechanisms, allowing positioning at any angle; the telescopic hydraulic rod 203 drives the multi-section structure of the multi-section telescopic arm 204 to achieve length extension and retraction to adapt to different window or door opening sizes; the angle adjustment rod 205 adjusts the tilt angle of the arm section through changes in hydraulic pressure to assist the support arm 2 to reach the required height.

[0037] Preferably, the working platform 3 includes: a platform frame 301 , a first telescopic base 302 , a second telescopic base, a counterweight box 304 and a working basket 305 .

[0038] The platform frame 301 is connected to the support arm 2 , and the first telescopic base 302 and the second telescopic base 303 are symmetrically arranged on both sides of the platform frame 301 and can be telescoped relative to the platform frame 301 .

[0039] The counterweight box 304 is arranged at the end of the second telescopic base 303, and the working basket 305 is arranged at the end of the first telescopic base 302. During the operation, the first telescopic base 302 and the second telescopic base 303 are synchronously extended and shortened relative to the platform frame 301.

[0040] Preferably, the work basket 305 is surrounded by guardrail structures to provide all-round protection to prevent personnel, tools, or materials from falling from height. The work basket 305 is used to carry construction workers to the corresponding exterior wall work surface for construction work. The counterweight box 304 is equipped with a counterweight based on the load of the work basket 305.

[0041] Preferably, when the support arm 2 of the work platform 3 moves from inside a building to outside, the first and second telescopic bases 302 and 303 are retracted to ensure that the work platform 3 can pass through door and window openings. When the work platform 3 is extended to a working surface on the building's exterior wall, the first and second telescopic bases 302 and 303 simultaneously extend based on the working range, allowing the work basket 305 to reach the corresponding working surface. The synchronized movement of the first and second telescopic bases 302 and 303 not only allows the corresponding work basket 305 to be delivered to the predetermined working surface, but also maintains the center stability of the work platform 3.

[0042] Working principle of this application's indoor adjustable high-altitude construction working device: (1) Movement and positioning The indoor adjustable construction aerial work device moves to the target position on the indoor ground through the bottom wheel group 102. After arriving at the target position, the operator activates the wheel group locking device through the control panel of the electromechanical box 105, and the mechanical brake locks the wheel group to ensure that the equipment is fixed.

[0043] (2) Support arm expansion and adjustment Adjustment of the hydraulic strut 104: The electromechanical box 105 drives the high-pressure pump of the hydraulic box 103, and the hydraulic oil enters the hydraulic strut 104 through the oil circuit, pushing the strut to extend and lifting the mobile body to a preset height.

[0044] Support Arm Extension and Rotation: Support Arm 2's bracket 202 is electrically or hydraulically driven to rotate and position itself in the direction of the target window or door opening. A telescopic hydraulic rod 203, utilizing a multi-stage sleeve structure, is hydraulically extended in sections, adapting the arm's length to the opening size. Angle adjustment rods 205 hydraulically adjust the angle of each arm segment. Sensors on the adaptive stabilization platform 206 monitor the tilt angle in real time, and hydraulic valves automatically compensate and adjust to ensure the support arm is level.

[0045] (3) Counterweight adjustment and stability The support arm counterweight 201 adjusts its position and weight distribution manually or automatically via sliding tracks based on the extension length and load, balancing torque and preventing tipping. The counterweight box 304 on the work platform is synchronized and linked, monitoring changes in the platform's center of gravity via a load cell. It automatically adjusts the position of the counterweight or the amount of fluid in the counterweight as needed to maintain overall stability.

[0046] (4) Operation platform deployment Platform frame extension: The telescopic base is extended along the guide rail under hydraulic or electric drive to increase the working area and adapt to different window opening widths or construction requirements.

[0047] Safety protection: The guardrail structure is locked to the platform frame through buckles to form a closed protection area. The top and surrounding protective nets prevent falling. At the same time, the platform frame integrates safety devices such as seat belt fixing points.

[0048] (5) Intelligent monitoring and control The adaptive stable platform 206 collects data in real time through the inclination sensor and pressure sensor. The control module analyzes the information such as inclination and load distribution, and automatically adjusts the pressure of the support arm hydraulic rod or the counterweight position to ensure the horizontal angle of the platform.

[0049] The electromechanical box is integrated with an emergency stop button, which can cut off all power output with one click in case of an emergency, and the hydraulic system will be automatically locked.

[0050] Core system collaboration Hydraulic system: The hydraulic box provides power for all hydraulic actuators (hydraulic struts, telescopic hydraulic rods, support hydraulic rods, angle adjustment rods), monitors the oil pressure through pressure sensors, and automatically shuts down and alarms in case of abnormalities.

[0051] Electronic control system: The PLC controller of the electromechanical box is the core, integrating the operation panel, sensor feedback, and motor drive module to achieve: a. Operation instruction analysis (such as height and angle adjustment); a. Real-time processing of sensor data and attitude adjustment; a. Safety interlock (if the wheel set is not locked, the support arm will not move).

[0052] Adaptive adjustment mechanism: Through closed-loop feedback from the sensor and hydraulic actuator, it dynamically compensates for tilt or displacement caused by uneven ground and load changes.

[0053] Workflow Summary Mobile positioning → Wheel lock → Hydraulic strut lifting → Support arm angle adjustment → Adaptive stable platform correction → Work platform deployment + counterweight adjustment → Safety protection deployment → Start aerial work.

[0054] This application overcomes the limitations of traditional fixed aerial work platforms, which struggle to adapt to complex indoor environments, by utilizing the coordinated extension and angle adjustment of multiple boom sections, combined with the omnidirectional coverage of a rotating bracket. Through closed-loop feedback from sensors and hydraulic actuators, tilt caused by uneven surfaces and load variations is compensated in real time, improving stability. Intelligent linkage between the counterweight and support arm movement eliminates the risk of tipping caused by traditional fixed counterweights.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
