Description

Technical Field

[0001] This utility model relates to the technical field of small mobile external hanging baskets, specifically to a small, mobile, and retractable external hanging basket for trestle construction. Background Technology

[0002] Currently, for the construction of cantilevered walkway platforms in water-adjacent scenarios such as riverbanks, the work on the suspended side mainly relies on fixed cantilevered scaffolding. However, existing fixed cantilevered scaffolding has the following significant technical defects in long-distance walkway construction, making it difficult to meet the requirements of efficient, stable, and safe operation: (1) Poor construction continuity and high difficulty in erection: The working surface outside the boardwalk is usually long (such as a hundred-meter-long riverside boardwalk). When using a fixed cantilevered basket, it is necessary to repeatedly erect and dismantle the basket along the working surface. Moreover, the outer area of ​​most riverside boardwalks is restricted by the river, and the construction space is narrow. The erection and anchoring of the fixed basket is extremely difficult, which not only consumes a lot of manpower and material resources, but also frequently interrupts the construction process, seriously reducing the construction efficiency. (2) Insufficient safety of operation: Construction workers need to enter the fixed basket from above the fence or enclosure of the boardwalk that has been completed. During this process, the center of gravity of the person moves significantly upward. The support structure of the traditional fixed basket only relies on a single cantilever anchor, which cannot adapt to the center of gravity shift. It is easy for the basket to sway, tilt or even overturn, making it difficult to ensure the personal safety of the construction workers. (3) Low elevation control accuracy and inability to maintain continuous positioning: For processes with elevation accuracy requirements, such as the installation of railings on the outer side of the walkway and the spraying of anti-corrosion coatings, every time a new fixed scaffold is built, the elevation must be measured again and the height of the scaffold must be adjusted. It is impossible to achieve continuous elevation positioning along the work surface. Frequent elevation calibration not only increases the number of operation steps, but also easily leads to inconsistent construction quality (such as railing height deviation and uneven coating thickness), affecting the overall quality of the project.

[0003] In summary, existing fixed cantilevered scaffolding cannot meet the construction needs of cantilevered walkways on the suspended side in long-distance, water-adjacent scenarios. There is an urgent need for a new type of external scaffolding equipment that can solve the problems of "low efficiency, poor safety, and difficulty in controlling elevation". Utility Model Content

[0004] The purpose of this utility model is to provide a small, movable, and retractable external hanging basket for trestle construction to solve the problems existing in the prior art. This equipment is characterized by being movable, easy to assemble and store, and having relatively stable elevation. It can reduce the requirements for the working surface environment and effectively improve the efficiency, quality and safety of construction on the suspended side of the cantilevered trestle. It is suitable for the auxiliary installation and subsequent maintenance of riverside trestle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small, movable, and retractable external hanging basket for trestle construction, comprising a movable base, a counterweight layer disposed on the upper part of the movable base, a detachable and assembleable rod assembly, and a lightweight steel hanging basket detachably connected to the rod assembly; The rod assembly consists of an adjustable horizontal bar and an adjustable vertical bar, which are assembled and fixed by connecting clamps; the lightweight steel basket is located at the bottom of the extended suspension of the rod assembly.

[0006] To further optimize this utility model, the following technical solutions may be preferred: Preferably, the connecting clamp includes a four-way connecting clamp and a detachable vertical rod fixing clamp. The four-way connecting clamp can slide along the axial direction of the rod and can be rotated inward to lock.

[0007] Preferably, the adjustable crossbar is a detachable snap-on telescopic structure for adjusting the lateral distance; the adjustable vertical bar is provided with several adjustment holes for precise adjustment of the vertical height.

[0008] Preferably, the movable base is also provided with an independent storage layer for storing disassembled rod components, connecting clamps and related accessories.

[0009] Preferably, the counterweight layer is provided with multiple counterweight blocks stacked on top of each other.

[0010] Preferably, the rod assembly and the movable base are further provided with intersecting diagonal braces and scissor braces.

[0011] Preferably, the movable base is a rigid support structure, and the upper bearing surface is detachably connected to the counterweight layer and the storage layer.

[0012] The needle of this invention has the following significant beneficial effects: (1) Significantly improves construction continuity and efficiency: This invention replaces the traditional fixed suspended platform's "single-set-up-disassemble" mode with a rigid, movable base equipped with casters. During construction, the base can be moved along the walkway to a new work point simply by loosening the connecting clamps, eliminating the need to repeatedly build supports and completely solving the problem of frequent construction interruptions over long distances. Furthermore, the "two-person, four-hand assembly" design of the lightweight steel suspended platform and its components, along with the quick-adjustment structure of the detachable, snap-lock telescopic crossbars, significantly shortens the equipment assembly and position adjustment time, increasing construction efficiency by more than 30% compared to traditional fixed suspended platforms.

[0013] (2) Significantly enhances operational safety and stability: On the one hand, the counterweight layer on the upper part of the movable base can flexibly adjust the weight by stacking counterweight blocks, which can adapt to the stability requirements of the suspended platform load (construction personnel + tools) and avoid the equipment from tipping over; on the other hand, the diagonal braces and scissor braces distributed between the rod components and the base form a triangular stability structure, which, together with the rotatable and lockable four-way connecting clamps, effectively suppresses the swaying and displacement of the suspended platform during construction, solves the tilting risk caused by the "center of gravity shift" of traditional fixed suspended platforms, and ensures the personal safety of construction personnel.

[0014] (3) Achieve precise and continuous control of elevation and position: This utility model uses a combination structure of "adjustable vertical rod (with several adjustment holes) + adjustable horizontal rod (plug telescopic type)" and the axial sliding function of the four-way connecting clamp to precisely control the vertical height of the suspended platform (adjustment accuracy ±5mm) and the lateral crossing distance (adapt to different walkway fence widths); and when moving the construction, it is only necessary to keep the adjustment parameters of the rod components unchanged to achieve "continuous elevation positioning" along the working surface, avoiding the problem that the elevation of the traditional suspended platform needs to be recalibrated for each operation, and effectively ensuring the consistency of construction quality of railing installation, coating spraying and other processes.

[0015] (4) Excellent portability and recyclability: The independent storage layer on the movable base can be used to store the disassembled rod components, connecting clamps and accessories, avoiding the loss of parts; at the same time, all parts of the equipment adopt a detachable connection design, and the overall weight is light (40% lighter than traditional fixed baskets), which makes it easy to transport to different construction sites for reuse. In addition, the use of lightweight steel and universal counterweights reduces the manufacturing cost and the service life can reach more than 5 years, which is in line with the concept of green construction.

[0028] II. Construction Operation Steps This embodiment uses the "installation of railings on the outer side of a riverside boardwalk" as an example to explain in detail the usage process of this utility model: (1) Preparations before construction Push the movable base 1 to the starting point of the boardwalk construction (near the river), and step on the universal wheel brake to fix the position of the base; according to the construction load (1 construction worker + 20kg tools), stack 4 concrete counterweights on the counterweight layer 2, and prevent the counterweights from sliding by cooperating with the positioning grooves at the bottom of the counterweights and the positioning bosses of the base 1.

[0029] (2) Assembly of rod components Take out the adjustable horizontal bar 81, adjustable vertical bar 82, connecting clamps and diagonal braces 4, and scissor braces 5 from the storage layer 3: First, fix the two adjustable vertical bars 82 to the preset connection points of the base 1 through the detachable vertical rod fixing clamps 7. According to the height of the boardwalk fence (assuming 1.2m), adjust the vertical bar to a height of 1.8m and lock it by inserting bolts into the adjustment holes; Take one adjustable horizontal bar 81 and connect it to the top of the two vertical bars through the four-way connecting clamps 6. Push the four-way connecting clamps 6 to slide along the axial direction of the vertical bar so that the extended end of the horizontal bar crosses the boardwalk fence (extended length 0.5m). Rotate the clamp bolts to lock the position; Install the diagonal braces 4 (each vertical bar is equipped with 2 diagonal braces, respectively connecting the base corner to the vertical bar at 1 / 2 height and 2 / 3 height) and the scissor braces 5 (cross connecting the two vertical bars at 1 / 2 height). Tighten all connection points with bolts to ensure that the rod assembly does not shake.

[0030] (3) Installation and position calibration of the suspended platform Connect the lightweight steel suspended platform 9 to the extended end of the crossbar 81 via the top hook. Adjust the bolts of the adjustable fixing structure 10 of the suspended platform members to make the bottom of the suspended platform flush with the working surface (railing installation position) on the suspended side of the walkway (error ≤ 5mm). Check the connection rigidity between the suspended platform and the member components to ensure that there is no looseness. Then, the construction personnel carry tools into the suspended platform.

[0031] (4) Mobile construction and location adjustment Once a section of railing is installed, the construction workers exit the suspended platform, release the brakes on the casters, and push the movable base 1 along the walkway to the new work point (the moving distance is set according to the length of the railing segment, usually 2m / segment). After reaching the new position, the casters are re-secured, and the stability of the counterweight layer 2 and the rod assembly is checked. The next section of construction can proceed directly without readjusting the lengths of the horizontal and vertical bars, thus achieving continuous elevation control.

[0032] (5) Disassembly and storage after construction After all construction is completed, first disassemble the lightweight steel suspended platform 9 and put it back into the storage layer 3; then remove the scissor brace 5 and the diagonal brace 4 in sequence, loosen the connecting clamps, retract the adjustable horizontal bar 81 to its shortest length, disassemble the adjustable vertical bar 82, and put it back into the partition area of ​​the storage layer 3 in categories; finally, remove the counterweight block of the counterweight layer 2, push the movable base 1 to the storage site, and complete the equipment storage.
