Description

Technical Field

[0001] This utility model relates to the field of construction equipment, specifically a scaffolding for high bridge piers. Background Technology

[0002] In the construction of high bridge piers, scaffolding serves as a crucial support and working platform, and its stability and flexibility are essential for construction efficiency and safety. However, traditional scaffolding systems often have many shortcomings and are unable to meet the stringent requirements of modern high bridge pier construction.

[0003] First, traditional scaffolding typically relies on manual operation for height adjustment, which is not only inefficient but also makes it difficult to guarantee the accuracy and stability of the adjustment. Especially in the construction environment of high bridge piers, due to the great height, manual adjustment is not only time-consuming and labor-intensive but also poses significant safety hazards.

[0004] Secondly, traditional scaffolding often has a simple support structure and lacks effective guidance and positioning mechanisms. This makes the scaffolding prone to swaying or shifting during lifting and lowering, seriously affecting the safety of construction workers and construction efficiency. Furthermore, the lack of an intelligent control system prevents real-time monitoring of the scaffolding's condition and timely corrective measures, further increasing construction risks.

[0035] This scaffolding system for high bridge piers achieves efficient support and flexible adjustment for high bridge pier construction through the coordinated work of the main frame, lifting frame 3, and support plate 4. The main frame, as the foundational support structure of the entire system, provides a stable lifting track for the lifting frame 3 through the cooperation of the base frame 1 and the adjusting frame 2. The lifting frame 3 is slidably mounted on the adjusting frame 2, enabling vertical height adjustment. The support plate 4 is installed at the bottom of the lifting frame 3 to directly support construction personnel and materials. The adjusting rope is wound and unwound by a dual-axis motor 10 driving a winding wheel 11. Guided by guide wheels 2 and 6, the rope is finally connected to the lifting ring 7 via hook 22, realizing the lifting operation of the lifting frame 3.

[0036] Main frame (including base frame 1 and adjustment frame 2)

[0037] Base frame 1: As the supporting foundation of the entire system, it is equipped with casters 18 for easy movement and has an equipment rack for placing the drive unit.

[0038] Adjustment frame 2: Located at both ends of the base frame 1, with an internal sliding groove for guiding and limiting the vertical movement of the lifting frame 3.

[0039] Lifting frame 3

[0040] It is slidably installed on the adjustment frame 2, and its side moves smoothly up and down by cooperating with the slide groove in the adjustment frame 2 through the slide rod 15.

[0041] The bottom of the lifting frame 3 is equipped with a lifting ring 7, and the top is symmetrically hinged with guide wheels 3 14. The lifting ring 7 is used to connect with the adjusting rope, and the guide wheels 3 14 are used to assist in guiding the lifting rope.

[0042] The front side of the lifting frame 3 is provided with a sliding groove 16 for connecting with the pallet 4 to ensure the lifting and lowering of the pallet 4 on the lifting frame 3.

[0043] Installed at the bottom of the lifting frame 3, the two ends are connected to the slide groove 16 on the lifting frame 3 through the slide rod 2, which ensures the stability of the pallet 4 during the lifting process.

[0044] The pallet 4 has adjusting rings 17 at both ends for connecting the lifting rope driven by the dual-axis motor 12 on the crossbeam 5.

[0045] drive system

[0046] Dual-shaft motor 10: Installed in the equipment frame on the base frame 1, each of its two output ends is equipped with a winding wheel 11, which is connected to the lifting ring 7 at the bottom of the lifting frame 3 through the adjustment rope, and is responsible for controlling the overall lifting action of the lifting frame 3.

[0047] Dual-shaft motor 12: Fixed on the crossbeam 5, with winding wheels 13 installed on the output shafts at both ends. It is connected to the adjusting rings 17 at both ends of the pallet 4 via lifting ropes, and is used to adjust the lifting action of the pallet 4 on the lifting frame 3, and to ensure that the pallet 4 always remains horizontal.

[0048] Guidance and Positioning Mechanism

[0049] A crossbeam 5 is installed on the lifting frame 3. The bottom of the crossbeam 5 is hinged to a guide wheel 6. The bottom of both ends of the base frame 1 is hinged to guide wheels 2. These guide wheels help to adjust the rope to correctly transmit torque and reduce friction loss.

[0050] The eccentric adjustment wheel 9 is installed at both ends of the equipment frame to adjust the direction of the adjustment rope, ensuring that the rope can be accurately guided from the take-up wheel 11 to the guide wheel 2 and back to the guide wheel 6, and finally reach the lifting ring 7.

[0053] Tilt detection sensor 21: Installed at the bottom of the base frame 1, it monitors the attitude change of the pallet 4 in real time and feeds the data back to the controller 19 so that corrective measures can be taken in time. When the tilt attitude is too large, the dual-axis motor 10 or the dual-axis motor 10 is shut down in an emergency to prevent the operator from standing unstable on the pallet 4.

[0054] Power module 20: Installed on the base frame 1 and crossbeam 5 respectively, it supplies power to the entire system, including dual-axis motor, controller 19 and other electronic components. Power module 20 can use conventional batteries or capacitors. Power module 20 can be used by connecting to the mains power or charging.

[0055] Safety features

[0056] Using steel wire rope 23 as both the adjustment rope and the lifting rope increases the strength and durability of the system.

[0057] The 18 casters are equipped with wheel locks, which enhances the stability of the scaffolding when it is not in use.

[0058] The tilt detection sensor 21, combined with wireless communication, provides intelligent safety monitoring capabilities and can respond quickly when anomalies are detected.

[0059] Detailed Explanation of Preferred Technical Solutions

[0060] Sliding connection structure: Through the design of slide groove one and slide rod one 15, slide groove two 16 and slide rod two, not only is the installation process of lifting frame 3 and pallet 4 simplified, but their vertical movement accuracy and stability are also improved.

[0061] Dual-axis motor drive: Dual-axis motor 10 and dual-axis motor 212 are used to control the lifting frame 3 and the pallet 4 respectively, making the operation more flexible and precise, and also facilitating maintenance and repair.

[0063] Material selection: Steel wire rope 23 is selected as the rope material to ensure sufficient tensile strength and durability, making it suitable for long-term outdoor use.

[0064] Detailed Workflow

[0065] Preparation stage

[0066] Assembly and positioning

[0067] Place the base frame 1 in a suitable position and secure it with the wheel locks on the casters 18 to ensure its stability.

[0068] Adjustment frames 2 are installed at both ends of the base frame 1 so that the lifting frame 3 can slide up and down in the inner sliding groove. The adjustment frames 2 can be assembled with the base frame 1 by welding or bolting.

[0069] Install the support plate 4, and connect its two ends to the slide groove 16 on the front side of the lifting frame 3 through the slide rod 2, so as to ensure the stable lifting and lowering of the support plate 4 on the lifting frame 3.

[0070] Connect power and initialize system

[0071] Power is supplied to the power modules 20 on the base frame 1 and the crossbeam 5 respectively, ensuring that all electrical components are working properly.

[0072] Start the controller 19 and communicate with the dual-axis motor 10 and dual-axis motor 12 via the wireless transceiver to complete the system's self-test and initialization settings.

[0073] Check the status of tilt detection sensor 21 to confirm that it is correctly installed and has established a wireless connection with controller 19.

[0074] Lifting operation procedure

[0075] Start the lifting platform to rise / lower 3

[0076] Users send remote or local control commands to controller 19 via wireless remote control to indicate whether the entire scaffolding needs to be raised or lowered.

[0077] After receiving the command, the controller 19 sends a corresponding signal to the dual-axis motor 10 or the dual-axis motor 12 to start or stop the motor.

[0078] The dual-axis motor 10 drives the winding wheel 11 to rotate, winding or releasing the adjustment rope. The adjustment rope passes sequentially through the eccentric wheel 9, the second guide wheel, and the first guide wheel 6, finally reaching the lifting ring 7 at the bottom of the lifting frame 3.

[0079] As the adjusting rope tightens or loosens, the lifting frame 3 rises or falls smoothly along the slide groove inside the adjusting frame 2.

[0080] Adjustment of tray 4

[0081] After the position of the lifting frame 3 is adjusted, the position of the pallet 4 can be further adjusted by starting the dual-axis motor 12 on the crossbeam 5 according to the usage requirements.

[0082] The dual-axis motor 12 drives the winding wheel 13 to rotate, and the force is transmitted to the adjusting rings 17 at both ends of the pallet 4 via the lifting rope and the guide wheel 14.

[0083] The tension of the lifting rope allows the pallet 4 to rise and fall further on the lifting frame 3, expanding the flexibility of the device.

[0084] Security monitoring and protection mechanisms

[0085] Real-time monitoring

[0086] The tilt detection sensor 21 continuously monitors the attitude changes of the base frame 1 and transmits the data to the controller 19.

[0087] If an abnormal tilt angle is detected (e.g., exceeding a set threshold), the controller 19 will immediately trigger an alarm and automatically stop all motor activity to prevent accidents.

[0088] Routine maintenance and inspection

[0089] Regular inspection

[0090] Regularly inspect the wire rope 23 to ensure there are no problems such as wear or breakage; replace the wire rope 23 with a new one if necessary to maintain the reliability of the system.

[0091] Clean the surface of the guide wheel to remove any foreign objects that may affect the rope's movement and ensure that the rope passes smoothly through each guide point.

[0092] Performance testing

[0093] Regularly perform lifting tests to verify the performance of the motor, ropes, and guide devices, and promptly identify and resolve potential problems.

[0094] Through the detailed workflow described above, the high bridge pier scaffolding not only provides an efficient and flexible operating experience, but also incorporates a variety of intelligent safety features to ensure stable and reliable operation even in complex environments.

[0095] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
