Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a movable combined suspended basket device for the maintenance and reinforcement of aqueducts. Background Technology

[0002] In water conservancy and hydropower projects, the repair and reinforcement of some old aqueducts are involved. An aqueduct is a hydraulic structure used to transport water across terrain obstacles such as valleys, rivers, and roads. It connects to a main canal at both ends. An aqueduct is an elevated water conveyance structure, mainly composed of a U-shaped channel, supporting structure, and foundation. The construction parts of aqueduct repair and reinforcement are mainly divided into three categories:

[0003] (1) The inside and top of the tank body (including the inner wall, the inner bottom plate, and the cross bracing beams);

[0004] (2) The outer wall of the trough and the eaves, and the bottom of the outer wall of the trough;

[0005] (3) The frame supports the front, back, left and right side walls.

[0006] The investigation found that items (2) and (3) require the use of suspended platform construction. Traditional suspended platform construction requires the setting of two types of suspended platforms: side longitudinal suspended platforms and bottom transverse suspended platforms. These two types of suspended platforms need to be constantly erected, dismantled and moved to cover the entire aqueduct construction work surface.

[0007] The erection, dismantling, and relocation of suspended platforms consume a significant amount of time, reducing work efficiency and increasing construction costs. Traditional suspended platforms require substantial counterweights and place high demands on the load-bearing capacity of older aqueducts.

[0008] Therefore, it is necessary to propose a movable combined suspended platform device for the maintenance and reinforcement of aqueducts to address the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figures 1 to 10 As shown, one embodiment of this utility model is provided:

[0035] A movable combined suspended platform device for aqueduct maintenance and reinforcement includes a movable suspension frame 100 and a combined suspended platform 200. The movable suspension frame 100 is entirely made of national standard Q235 rectangular steel pipe. All joints of the suspension frame members, as well as the members and pulleys, are welded together using J422 (E4303) welding rods and a perimeter welding method.

[0036] The ZPL800 model is selected for the operation platform of the modular suspended platform 200. It is made of steel and the dimensions of a single unit are approximately 2.5×0.76×1.45m. The platform dimensions (length×width×height) of the first longitudinal suspended platform 4 and the second longitudinal suspended platform 6 are 2500×760×1450mm, and the platform dimensions of the transverse suspended platform 5 are (2500+2500)×760×1450mm.

[0037] The modular suspended platform 200 includes a first longitudinal suspended platform 4, a second longitudinal suspended platform 6, and a transverse suspended platform 5. The lower two sides of the movable frame are connected to the first longitudinal suspended platform 4 and the second longitudinal suspended platform 6, respectively. The two ends of the transverse suspended platform 5 are connected to the lower parts of the first longitudinal suspended platform 4 and the second longitudinal suspended platform 6, respectively. Specifically, the lifting and lowering of the suspended platform is achieved by a hoist. Only one set of modular suspended platforms 200 is needed to cover the outer wall and bottom of the U-shaped aqueduct at one time.

[0038] Furthermore, the mobile hanger 100 includes a base frame 7, a stiffening frame 1, a first pulley assembly 3, and a second pulley assembly 9. The stiffening frame 1 is installed on the upper part of the base frame 7, the first pulley assembly 3 is installed on the lower part of the base frame 7, and the second pulley assembly 9 is installed on the bottom side of the base frame 7. The mobile hanger is welded from square tubing. The first pulley assembly 3 allows the base frame 7 and the stiffening frame 1 to move above the aqueduct, enabling continuous repositioning without disassembly or assembly. The second pulley assembly 9 restricts the lateral movement of the hanger, ensuring that the mobile hanger 100 always travels along a set route. The design of the first pulley assembly 3 and the second pulley assembly 9 allows the entire equipment to move via the pulleys of the first pulley assembly 3 and the second pulley assembly 9, reducing frequent disassembly and assembly processes and saving construction time.

[0039] Simultaneously, four sets of first pulley assemblies 3 are installed on both sides of the lower part of the hanger. Each first pulley assembly 3 is connected to an adjustable top support and a triangular support. The adjustable top support is inserted into the triangular support for adjustment, maintaining a 20-30mm gap between the lateral pulleys and the outer wall of the aqueduct. The adjustable top support specifications are φ36×700mm, with an adjustment range of 200-400mm. The outer wall of the aqueduct restricts the lateral displacement of the movable hanger, ensuring that the hanger remains in a suitable position in the middle of the top eaves of the aqueduct side wall during movement. The first pulley assembly 3 uses 4-inch directional pulleys, with a single pulley bearing a load of not less than 850kg.

[0040] Furthermore, a braking component 10 is provided on the bottom frame 7 near the first pulley group.

[0041] Furthermore, the braking component 10 includes a flange 101, a lead screw 102, a nut 103, and a pad 104. The upper end of the lead screw 102 is connected to the flange 101, the lower end of the lead screw 102 is connected to the pad 104, and the lead screw 102 is connected to the nut 103 and passes through the bottom frame 7.

[0042] Furthermore, the upper part of the second pulley assembly 9 is provided with an anti-overturning rod 2. Specifically, the anti-overturning coefficient of the mobile gantry can be increased by the anti-overturning rod 2. The mobile gantry is temporarily fixed during operation by the braking component 10. The entire mobile gantry 100 and the combined basket 200 adopt a symmetrical design, which can save the counterweight, reduce unnecessary weight, and reduce the requirements for the load-bearing capacity of the aqueduct.

[0043] Furthermore, the second pulley assembly 9 includes a fixed rod 901, an adjustable top support 902, and a pulley 903. One end of the adjustable top support 902 is threadedly connected to the fixed rod 901, and the adjustable top support 902 is connected to the pulley 903.

[0044] Furthermore, both the bottom frame 7 and the stiffening frame 1 are made of hollow square tubes spliced ​​together.

[0045] Furthermore, a stiffening plate 8 is connected between the two hollow square tubes, which increases the rigidity of the bottom frame 7 and the stiffening frame 1.

[0046] Furthermore, the first pulley assembly 3 uses four straight heavy-duty rubber wheels, and the pulleys are directional wheels.

[0047] The advantages of this invention are: It adopts a symmetrical design, eliminating the need for counterweights, reducing unnecessary weight, and lowering the load-bearing capacity requirements of the aqueduct; a single erection can cover all construction areas of the U-shaped aqueduct, including the outer wall and eaves, the bottom of the outer wall, and the front, rear, left, and right side walls of the support frame. Traditional suspended platforms require at least two types of erection: longitudinal and transverse. This invention can be moved via pulleys, reducing frequent disassembly and assembly processes and saving construction time.

[0048] Working principle: The lower first pulley assembly 3 of the mobile gantry 100 is installed on the aqueduct 11, and two guide rails are provided on the aqueduct 11; the lower first pulley assembly 3 of the mobile gantry 100 is connected to the guide rails, and the combined suspended basket 200 is connected to the winch on the mobile gantry 100 through a steel wire rope.

[0049] During construction, the mobile gantry 100 can move along the guide rail on the aqueduct 11. The winch is connected to the combined suspended platform 200 via a wire rope, thereby adjusting the lifting and lowering of the combined suspended platform 200. Workers carry out construction on the aqueduct 11 on the combined suspended platform 200.

[0050] For example, a 100m long aqueduct typically contains 6 supporting frames. During traditional suspended platform construction, the 6m long longitudinal suspended platform needs to be erected and dismantled at least 32 times, and the 0.76m wide transverse suspended platform needs to be erected and dismantled at least 65 times, for a total of at least 97 times. However, the new mobile modular suspended platform device only requires the bottom transverse suspended platform to be erected and dismantled when crossing the supporting frames, for a total of 6 times.

[0051] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
