Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, in particular to an electric side-hanging cage. Background Art

[0002] In bridge construction, concrete crash barriers, as critical safety components of the superstructure, often require numerous follow-up operations after completion, including cleaning the sides of the barriers, applying slogans and reflective signage, applying surface coatings and decoration, and installing and maintaining ancillary facilities. These operations, which often occur on the outer edge of the bridge or on the exterior facade of the barriers, pose risks associated with working at height and place high demands on the stability, safety, and operational flexibility of the construction platform.

[0003] Currently, to complete these construction tasks, construction companies generally use auxiliary methods such as crane baskets, mobile installation and removal vehicles, aerial work platforms, tower crane cages, external platforms, or temporary scaffolding. While these methods can accomplish the corresponding tasks to a certain extent, due to the complex and variable locations of bridges, especially those crossing rivers, railways, or elevated sections, the limited construction sites, high road traffic pressure, and insufficient space for equipment deployment, traditional equipment has significant shortcomings in flexibility and adaptability. Furthermore, these equipment, often heavy machinery or large components, are expensive to purchase and operate, and the frequent relocation and scheduling of construction sites consumes time, manpower, and financial resources.

[0004] To address the above issues, some construction units have attempted to use hanging basket trolleys (side-mounted platforms) to complete work tasks on the outside of bridge guardrails. Hanging basket trolleys are generally constructed of lightweight metal components and fixed to the anti-collision guardrail through an anchoring structure. They are suspended on the outside of the bridge for use by personnel and tools. However, most existing hanging basket trolleys are manually pushed or towed sliding structures, lacking an autonomous power system. The movement process is time-consuming and labor-intensive, especially when long bridge sections or construction requires frequent section changes, resulting in extremely low efficiency. In addition, existing hanging basket trolleys still need to be improved in terms of human-machine collaboration, safety control, load capacity, and structural stability, making it difficult to meet the needs of modern bridge engineering for efficient, safe, and intelligent construction equipment.

[0005] Existing construction equipment relies on heavy machinery or large platforms, which are restricted by site and traffic conditions and have poor applicability. Traditional side-mounted construction platforms are mostly non-electric or semi-automatic structures, with low mobility efficiency and labor-intensive operations. There is a lack of integrated solutions suitable for long bridge sections, multiple processes, and high-frequency mobile operations. It is difficult to carry out efficient and safe outer side construction operations in complex bridge sections such as those across rivers and roads.

[0006] In summary, it is found that the existing technology has at least the following technical problems: The construction equipment outside the existing bridge has the technical problems of poor applicability, low moving efficiency and low high-altitude operation efficiency due to site condition limitation.

[0035] When the application is carried out, the walking passages of the escalator section 11, the connecting ladder section 12 and the hanging cage section 13 are connected by setting the ladder steps 4 near the outer side of the fence 7, and the personnel can go up and down the working platform more smoothly from the bridge through the escalator section 11, the connecting ladder section 12 and the hanging cage section 13. The hanging cage section 13 is set to be a relatively drooping structure, and the length of the drooping part is limited by the length of the escalator section 11, so that the force moment is balanced, and the escalator section 11 and the hanging cage section 13 support each other, thereby ensuring the stability of the high-altitude structure suspension. The double-layer ladder steps 4 are set to be one layer inside and one layer outside in the escalator section 11, which can be used for inserting the counterweight hanging bracket 6, and the counterweight hanging bracket 6 is fixed between the ladder steps 4 through the hooks 61, so as to stably carry the construction tools or heavy objects and improve the control ability of the hanging cage gravity center to prevent tilting and swinging.

[0036] The overall structure of the cross-type hanging cage 1 superimposed with the counterweight hanging bracket 6 can effectively solve the problems of equipment gravity center deviation and poor passage in high-altitude operation in the construction site, and enhance the stability of the structure and the safety of the construction personnel.

[0039] In the application process, the construction personnel hangs the ladder section 11 and the hanging cage section 13 on both sides of the fence 7 on the bridge, presses the pulley 22 against the surface of the fence 7 by rotating the screw handle 23, and then uses the movable locking ring 231 to position, to complete the stable locking of the cross-type hanging cage 1, and the whole process does not need additional tools and is convenient to operate on site. When the equipment needs to be unloaded or the construction section needs to be replaced, only the movable locking ring 231 is unlocked and the screw handle 23 is loosened, and after the pulley 22 is away from the fence 7, the hanging cage can be taken down as a whole; the structure is intuitive to operate, the locking force is strong, and the installation efficiency and use safety of the electric side hanging cage device in the high position can be significantly improved, and the displacement or falling of the equipment caused by wind load, human error and other factors can be avoided.

[0040] In addition, the outer ring of the pulley 22 is made of elastic rubber material to improve the adhesion to the surface of the fence 7 and reduce the wear when rolling and pressing the fence 7.

[0042] In the application process, the construction personnel controls the driving wheel 32 to rotate forward or reverse by the control handle 33 arranged on the handrail of the hanging cage section 13, so as to drive the whole hanging cage device to move forward or backward stably along the bridge anti-collision fence 7.

[0043] In addition, the surface of the driving wheel 32 is provided with gripping texture or rubber coating to enhance the friction; the control module is embedded with a gyroscope or electronic limit, which is matched with the control of the control handle 33 and the driving wheel 32 to realize speed limit control and attitude monitoring; and the control handle 33 is also integrated with a state display lamp for prompting power, running direction, abnormal alarm and other information.

[0044] The specific structure of the walking driving unit 3 is shown in the embodiment.Figs. 1-3 As shown, the end of the hanging cage section 13 is a hanging cage floor 131 for workers to stand on, cooperating with the guardrails of the hanging cage section 13 to realize the safe standing of workers on the outside of the fence 7 to perform construction on the outer facade of the fence 7 of the bridge.

[0045] In application, workers can enter the hanging cage section 13 through the ladder section 11 and stand on the hanging cage floor 131 arranged at the end thereof to perform cleaning, posting or maintenance work on the outer guardrail of the bridge; the floor area cooperates with the guardrails arranged therearound to form an effective work safety area, ensuring the stability and safety of workers in high-altitude working state; the simple and clear structure design with lowered gravity center facilitates the operation of workers to perform various construction tasks, effectively improving the work comfort and personnel protection capability.

[0046] The hanging cage floor 131 is made of anti-slip embossed aluminum alloy plate to improve the anti-slip performance; the guardrails are of detachable or foldable structure to adapt to different work radius requirements.

[0047] Based on the above embodiment of the electric side hanging cage, a safe use method of the electric side hanging cage is provided, which is executed by the electric side hanging cage and includes the following steps: S1, the electric side hanging cage is arranged across the bridge anti-collision fence 7, with the ladder section 11 located inside the fence 7, the connecting ladder section 12 across the top of the fence 7, and the hanging cage section 13 located outside the fence 7; S2, a plurality of walking locking units 2 arranged on the ladder section 11 and the hanging cage section 13 are used to press and lock along the inside and outside of the fence 7 respectively, so that the entire cross-type hanging cage 1 is stably fixed on the bridge anti-collision fence 7; S3, before starting the driving control system, the hanging cage section 13 is provided with an identification sensing unit 5 for identifying personnel, which is used to determine whether there is a worker in the hanging cage section 13; when the identification sensing unit 5 detects that there is a person in the hanging cage section 13, the control module allows the operation of the control handle 33 to drive the driving wheel 32 to rotate, thereby driving the cross-type hanging cage 1 to move along the anti-collision fence; S4, when the identification sensing unit 5 detects that the personnel leave the hanging cage section 13, the control module automatically stops the rotation of the driving wheel 32 and triggers the electric brake locking of the driving wheel 32 to prevent the movement of the hanging cage in the unattended state.

[0048] Specifically, the identification sensing unit 5 includes a pressure sensor 51 arranged on the hanging cage floor 131 of the hanging cage section 13 and an infrared sensor 52 arranged above the guardrail of the hanging cage section 13; the pressure sensor 51 is used to detect the load signal generated by the standing of personnel, and the infrared sensor 52 is used to identify whether there is a moving target in the hanging cage section 13; the control module determines whether the personnel are in place according to the sensing results of the pressure sensor 51 and the infrared sensor 52.

[0049] Further, when the recognition sensing unit 5 judges that the hanging cage section 13 is in an unoccupied state, the control module opens the electronic lock that controls the state of the wheel motor of the driving wheel 32, and the driving wheel 32 is in an electronically locked state and cannot rotate, thereby preventing the hanging cage from slipping; when a person reenters the hanging cage section 13 and the recognition sensing unit 5 confirms the in-place state, the control module releases the electronic lock of the driving wheel 32 again and allows the driving wheel 32 to resume operation.

[0050] In application, the construction personnel first accurately crosses the electrically powered side hanging cage on the bridge anti-collision fence 7, so that the escalator section 11 is stably located inside the fence, the hanging cage section 13 is suspended outside, and the connecting ladder section 12 is transversely arranged between the two to form a continuous passage; then, the plurality of walking locking units 2 arranged on the escalator section 11 and the hanging cage section 13 are compressed and locked, so that the hanging cage is firmly fixed on the fence 7 structure.

[0051] During operation, when the construction personnel enters the hanging cage section 13, the pressure sensor 51 arranged on the hanging cage floor 131 detects the load signal generated by the body weight of the personnel, and the infrared sensor 52 arranged above the fence detects the existence of the moving target. The control module judges that the personnel is in place under the condition that the double sensing results are satisfied at the same time, and starts the driving system to respond to the action of the control handle 33, so that the driving wheel 32 operates, thereby enabling the hanging cage to stably walk along the bridge anti-collision fence 7.

[0052] If the construction personnel leaves the hanging cage section 13, the system immediately detects that the personnel is out of place, the control module immediately stops the driving wheel 32 from operating, and the electronic lock triggers the electric locking mechanism, so that the driving wheel 32 is in a locked state, thereby preventing the hanging cage from slipping or misoperation in an unoccupied state, and ensuring the stability of the equipment and the safety of the operating personnel during high-altitude operation.

[0053] The above technical solution builds a cooperative safety logic of “person in operation and person out of operation” through sensing judgment and electric control linkage, effectively solves the problems of misoperation movement, empty load slipping, operation risk and the like of the traditional hanging cage, and greatly improves the intelligent level and essential safety protection capability of the high-altitude operation system.

[0054] In addition, the infrared sensor 52 is arranged in multiple, further adopts a double-area multi-angle configuration, realizes independent detection on the standing area and the leaning area, and enhances the judgment accuracy; the pressure sensor 51 further adopts a multi-point matrix arrangement, and distinguishes and judges abnormal heavy objects and personnel behaviors; the control module further integrates a buzzer and a sound-light alarm device, and synchronously sends a prompt signal when detecting that the personnel is out of place; the electronic lock adopts an electromagnetic brake structure and a mechanical tooth disc double braking structure, and is integrated on the driving wheel 32, thereby improving the anti-slipping capability and adapting to the safety requirements of different bridge slopes and construction loads.

[0055] Any technical features in the above embodiments can be combined, and for the sake of brevity, not all possible combinations are described.

The driving wheel is connected to the bottom outside the integrated box, and the driving wheel is provided with a wheel motor; The control handle is arranged on the handrail side of the hanging cage section. By rotating the control handle, the driving wheel is controlled to rotate forward or reverse, thereby driving the straddling hanging cage to move forward or backward on the fence.

5. The electric side hanging cage according to claim 4, characterized in that: The drooping length of the hanging cage section is greater than that of the escalator section, and the length of the portion of the hanging cage section that is longer than the escalator section is not greater than the overall length of the escalator section, so as to maintain the balance of the escalator section as a clamp for the hanging cage section.

6. The electric side hanging cage according to claim 5, characterized in that: The end of the hanging cage section is a hanging cage floor for construction workers to stand on. Together with the guardrail of the hanging cage section, construction workers can stand safely outside the fence to construct the fence facade of the bridge.

7. A method for safely using an electric side hanging cage, performed by the electric side hanging cage, characterized in that: The method comprises: S1, placing the electric side hanging cage across the anti-collision fence of the bridge, so that the escalator section is located inside the fence, the connecting ladder section spans the top of the fence, and the hanging cage section is located outside the fence; S2, through the multiple travel locking units set on the escalator section and the cage section, respectively, along the inner and outer sides of the fence are pressed and locked, so that the entire spanning cage is stably fixed on the bridge anti-collision fence; S3. Before starting the drive control system, the cage section is provided with a personnel identification sensor unit for determining whether a construction worker is present in the cage section. When the identification sensor unit detects that a person is present in the cage section, the control module responds to the operation of the control handle, thereby driving the drive wheel to operate and driving the straddling cage to move along the anti-collision guardrail. S4. When the recognition sensor unit detects that a person has left the cage section, the control module automatically stops the rotation of the drive wheel and triggers the electric brake to lock the drive wheel to prevent the cage from moving when no one is around.

8.
