[0037] To solve the problem that the conventional hanging device of the hanging basket cannot adapt to the construction conditions of the external thermal insulation of the aqueduct body, this application provides a lifting and hanging device for the external thermal insulation construction of the aqueduct body. The specific embodiments are as follows:

[0038] In one embodiment, please refer to Figure 1 and Figure 2 , a lifting and hanging device for the external thermal insulation construction of the aqueduct body, includes a structure frame 1, a lifting assembly 2, a hanging basket 3, and a counterweight 4.

[0039] In this embodiment, the structure frame 1 is a frame structure with central symmetry and at least includes four support beams 11 that intersect in pairs; the symmetric structure has good stability and can provide a stable support for the overall device. The structure frame 1 is arranged on the top of the aqueduct body 8, and at least a pair of lifting assemblies 2 are symmetrically arranged at both ends of the structure frame 1. The steel wire ropes 21 of each lifting assembly 2 can be used to suspend the hanging basket 3, thereby realizing the lifting and hanging operation requirements of construction workers. To maintain the balance of the device during operation, a counterweight 4 is also placed on the structure frame x.

[0040] Among them, the lifting assembly 2 can be a winch, a crane, a hoisting winch, etc.; the support beam 11 can be selected from I-beams or other profiles that meet the strength requirements; the weight of the counterweight 4 is matched according to the number of construction workers and the weight of materials carried in the hanging basket 3, and the counterweight 4 is specifically arranged near the joints between the support beams 11.

[0041] Therefore, in the present application, a structural frame 1 adapted to the aqueduct body 8 is fabricated and arranged on the aqueduct body 8. Meanwhile, lifting assemblies 2 and hanging baskets 3 are symmetrically arranged on both sides of the structural frame 1. The hanging basket 3 is hoisted up and down by the symmetrically arranged lifting assemblies 2, thereby transporting construction workers to the required working areas, meeting the requirements for external thermal insulation construction of the aqueduct body 8, and the device has a simple structure, is stable and reasonable, and is convenient to implement.

[0042] In one embodiment, the lifting and suspension device for external thermal insulation construction of the aqueduct body 8 further includes a directional wheel 5. Four directional wheels 5 are provided and fixedly connected to the structural frame 1, and the four directional wheels 5 are respectively arranged near the intersection of each pair of supporting beams 11. By providing the directional wheels 5, the structural frame 1 can be given the function of moving, thereby realizing continuous operation of the device, and avoiding the situation that after the construction workers complete the external thermal insulation construction of the aqueduct body 8 in the current area, they need to return to the top of the aqueduct body 8 through the lifting assembly 2 and move the structural frame 1 before they can carry out subsequent external thermal insulation construction operations on the aqueduct body 8. Among them, after the directional wheel 5 is fixedly connected to the structural frame 1, it does not have the ability to turn, and the traveling direction of the directional wheel 5 is consistent with the extending direction of the aqueduct body 8, avoiding potential safety hazards caused by the turning of the directional wheel 5 during the working process.

[0043] Furthermore, at least one of the directional wheels 5 is provided with a driving element and a braking element, which can facilitate the movement of the device, avoid manually pushing the structural frame 1 forward, and save the physical strength of the operating personnel. At the same time, the braking element can prevent potential safety hazards caused by abnormal movement of the directional wheel 5 during the construction process while assisting the device to brake.

[0044] In one embodiment, an auxiliary beam 12 for fixing the safety rope 7 is further provided at the center of the structural frame 1, and both ends of the auxiliary beam 12 are fixedly connected to the supporting beam 11. Since the construction workers take the hanging basket 3 to carry out external thermal insulation construction of the aqueduct body 8, which belongs to high-altitude operation, the construction workers must wear the safety rope 7 during the construction process. By providing the auxiliary beam 12, it is convenient to fix the safety rope 7 on the narrow top of the aqueduct body 8.

[0045] In one embodiment, please refer to Figure 3 , the lifting and suspension device for external thermal insulation construction of the aqueduct body 8 further includes a connecting plate 6.

[0046] In this embodiment, the connecting plate 6 is detachably fixedly connected to the hanging basket 3. When the working height of the hanging basket 3 drops below the bottom end face of the aqueduct body 8, both ends of the connecting plate 6 can be respectively connected to the hanging baskets 3 on both sides of the aqueduct body 8 to construct a temporary working platform below the aqueduct body 8 for the construction workers to carry out external thermal insulation construction on the bottom of the aqueduct body 8. After the construction is completed, the connecting plate 6 can be removed to lift the hanging basket 3 back to its original position.

[0047] In one embodiment, two guiding ribs are further arranged along the extending direction of the top end surface of the trough body 8, and the directional wheels 5 are both located between the two guiding ribs, so as to prevent the directional wheels 5 from deviating from the trough body 8 during the movement of the device and threatening the life safety of construction workers.

[0048] In one embodiment, guardrails 13 are further provided at both end faces of the structural frame 1 adjacent to the trough body 8 to protect the construction workers operating on the top of the aqueduct trough body 8. At the same time, the guardrails 13 can also be used to support the safety rope 7 to prevent the safety rope 7 from being directly hung on the edge of the structural frame 1 and being quickly worn.

[0049] In summary, the specific implementation process of the present application is as follows:

[0050] The lifting and suspension device for the external thermal insulation construction of the aqueduct trough body 8 moves to the top of the aqueduct trough body 8 with the help of the directional wheels 5. Counterweight blocks 4 are placed on the structural frame 1 according to the number of people in the hanging basket 3 and the weight of the materials. The construction workers wear the safety ropes 7 and carry the relevant materials for the external thermal insulation construction of the trough body 8 and the connecting plates 6 and ride in the hanging basket 3. The lifting assembly 2 operates to lower the hanging basket 3 to the height required for the construction operation. The construction workers perform the external thermal insulation construction on both sides of the trough body 8 in the hanging basket 3; when the external thermal insulation construction of the bottom of the trough body 8 is required, the lifting assembly 2 continues to lower the hanging basket 3 so that the hanging basket 3 completely descends below the trough body 8. The construction workers on both sides of the hanging basket 3 cooperate with each other to assemble the connecting plates 6 onto the two hanging baskets 3 to form a temporary operation platform. The construction workers move from the hanging basket 3 to the connecting plates 6 to perform the external thermal insulation construction on the bottom of the trough body 8. After the bottom operation is completed, the connecting plates 6 are disassembled and retracted into the hanging basket 3; after the external thermal insulation construction of the current area of the trough body 8 is completed, the driving element drives the directional wheels 5 to move, thereby driving the device to the subsequent construction area; after the external thermal insulation construction of the aqueduct trough body 8 is completed, the lifting assembly 2 pulls back the hanging basket 3, and the construction workers in the hanging basket 3 return to the top of the trough body 8. Therefore, the lifting and suspension device for the external thermal insulation construction of the aqueduct trough body 8 of the present application adapts to the narrow conditions of the aqueduct trough body 8 and has the ability to move, and can provide continuous, reliable and safe support for the external thermal insulation construction of the aqueduct trough body 8.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present application.

[0052] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
