[0002] Suspended baskets are often used in high-altitude operations such as building construction and bridge construction. Although the technology is mature, there is still room for improvement in safety measures and ease of use. Although traditional suspended baskets are equipped with 2-3 safety hanging points, they are usually set outside the field of vision of the operators, which results in the operators not being able to observe the safety of the hanging points in time and causing danger. Traditional suspended baskets only emphasize the multiple hanging points of the suspended basket itself, but ignore the safety hanging points of the operators. Operators usually hang the safety rope on the guardrail of the suspended basket. Once the suspended basket fails, the safety of the personnel cannot be guaranteed.

[0003] Traditional hanging baskets mostly use a sheet-like truss assembly structure, which has the problems of large storage space and inconvenient transportation. It cannot meet the construction unit's needs for local materials and light asset operation, especially in overseas projects, and the application cost is high. Utility Model Content

[0004] The purpose of the utility model is to provide a lightweight standard truss hanging basket with multiple independent safety measures. By adding auxiliary hanging equipment within the field of vision of the operator, it is possible to avoid safety accidents caused by failure of the main hanging equipment outside the field of vision. By setting up an independent safety wire rope system, the safety of personnel can be guaranteed even if the hanging basket fails. By using finished aluminum alloy standard trusses, it is convenient for construction units to rent nearby and operate with light assets.

DETAILED DESCRIPTION

[0020] The utility model is described in detail and completely below in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. Before describing the utility model in conjunction with the accompanying drawings, it should be particularly pointed out that the technical solutions and technical features provided in each part of the utility model, including the following description, can be combined with each other without conflict.

[0021] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] The following is a further detailed description of the utility model in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows:

[0023] like Figure 1 As shown, the utility model provides a lightweight standard truss hanging basket with multiple independent safety measures, including a main hanging device system 1, a standard truss basket body 2 and an auxiliary hanging device system 3; the lower part of the main hanging device system 1 is connected to the standard truss basket body 2, and the upper part of the main hanging device system 1 is connected to the structure to be constructed;

[0024] The auxiliary sling system 3 includes: a first upper anchor 3-2, a first lower anchor 3-3 and a first connecting wire rope; the first upper anchor 3-2 is connected to the structure to be constructed, the first upper anchor 3-2 and the first lower anchor 3-3 are connected by the first connecting wire rope, and the first lower anchor 3-3 is connected to the standard truss basket 2.

[0025] In this embodiment, a demonstration project of strengthening a group of old bridges is taken as an example. There are 24 old bridges with a total of 58 spans. The single span of the bridge is 25 to 73 meters long and 10.3 to 10.9 meters wide. There are New Jersey guardrails on both sides of the bridge deck. The clearance under the bridge is 7 to 18 meters. There are mostly rivers or boulders under the bridge. The bottom of the beam construction includes pasting steel plates on the beam body, adding an extracorporeal prestressing system, etc., which requires the use of a hanging basket as a construction platform.

[0026] The auxiliary sling system 3 is a sling that is installed by personnel near the work point after the main sling system 1 and the standard truss basket 2 are installed. As a safety reserve, the biggest feature of this sling is that it is within the field of vision of the operator, and the operator can observe whether it is working normally at any time. The first lower anchor 3-3 is the C10 steel beam 1-4 as the lower anchor point, and the C10 steel beam 1-4 is connected to the standard truss basket 2.

[0027] Among them, the first upper anchor 3-2 is used as the upper anchor point. It is divided into two types: fixed hanging point and movable hanging point according to whether the hanging basket is moved for a long time. When it is a fixed hanging point, the first upper anchor 3-2 can be a rebar or an expansion bolt; when it is a movable hanging point, the first upper anchor 3-2 is a steel clamp 3-1, which is clamped on the horseshoe angle at the bottom of the I beam. The steel clamp 3-1 used in this project is a double-piece C8, with a steel plate at its end, with an angle of 45°, which fits the horseshoe of the I beam.

[0028] The present technical solution may also include the following technical details to better achieve the technical effect: the main hoisting device system 1 includes: a second upper anchor, a second lower anchor, a working steel wire rope 1-2, and a steel wire anti-slip device 1-3; the second upper anchor is connected to the upper part of the structure to be constructed, and is mainly fixed at the high point of the structure. The second upper anchor and the second lower anchor are connected by a working steel wire rope 1-2, and the second lower anchor is connected to the standard truss basket 2.

[0029] The main hoist system 1 is fixed at a high point such as the roof or the top of the guardrail. After the standard truss basket 2 is hoisted to the working position, 1-2 people with safety ropes are arranged to board the basket to install the auxiliary hoist system 3 and the independent wire rope 4-2 for personnel safety. In the acceptance checklist, the inspection of the auxiliary hoist within the field of vision and the inspection of the independent safety rope for personnel are listed as important items.

[0030] In this embodiment, the second upper anchor serving as the upper anchor point is an F-shaped C10 steel caliper 1-1 fixed on the bridge guardrail. Because the hanging basket needs to move in the longitudinal direction of the bridge, an industrial-grade caster 5-4 with a bearing capacity of 1 t is provided; the second lower anchor serving as the lower anchor point is a C10 steel beam 1-4, which is placed horizontally under the hanging basket truss; the working wire rope 1-2 connects the upper and lower working anchor points, and the wire anti-slip device 1-3 controls the length of the working wire rope 1-2 to realize the up and down movement of the hanging basket. In this embodiment, the wire anti-slip device 1-3 is a 1t-grade hand winch with a length of 9 to 15 m.

[0031] The present technical solution may also include the following technical details to better achieve the technical effect: the main hoisting device system 1 also includes a safety wire rope set 1-5; the safety wire rope set 1-5 includes: a third upper anchor, a third lower anchor and a safety wire rope; the third upper anchor is connected to the structure to be constructed, and the third upper anchor and the third lower anchor are connected by a safety wire rope, and the third lower anchor is connected to the standard truss basket 2.

[0032] In this embodiment, the third upper anchor is used as the upper anchor point, which is a φ20 steel bar hook directly hung on the bridge guardrail, and the third lower anchor is used as the lower anchor point, which is another C10 steel. The length of the safety wire rope is the installation length required after the hanging basket reaches the working position. The upper and lower anchor points of the safety wire rope set 1-5 are independent of the upper and lower anchor points of the main hanging device, so as to avoid the failure of the upper and lower anchor points of the main hanging device, which may cause the hanging basket to collapse.

[0033] The technical solution may also include the following technical details to better achieve the technical effect: the standard truss basket 2 includes: an aluminum alloy standard finished truss 2-1 and a flexible guardrail 2-2. The aluminum alloy standard finished truss 2-1 (commonly used stage lighting truss) is characterized by convenient rental, small footprint, light weight and easy installation. It is particularly suitable for construction units to rent nearby and operate with light assets. Different specifications of aluminum alloy standard trusses can be selected according to different requirements of the use load. The flexible guardrail 2-2 is set on the side of the aluminum alloy standard finished truss 2-1.

[0034] The stage lighting trusses that are easy to rent on the market include aluminum alloy trusses of different standard specifications of 20 to 60 cm, which can achieve a span of 8 to 26 meters and a load-bearing capacity of 80 to 1000 kg. In this embodiment, the hanging basket adopts a standard truss of 40 cm × 40 cm, a maximum span of 13.5 m, and a total load-bearing capacity of 500 kg. The technical advantages of using this type of truss include easy installation, mature technology, safety and reliability, and the economic advantages include convenient rental, not being limited by the high rental or procurement fees of the hanging basket manufacturer, and no need for warehouse storage and long-distance transportation turnover.

[0035] The technical scheme may also include the following technical details to better achieve the technical effect: the flexible guardrail 2-2 is composed of an aluminum alloy tube column 2-2-1, a steel wire rope, and a dense mesh 2-2-3; the aluminum alloy steel tube column is fixed to the aluminum alloy standard finished truss 2-1 with a pipe clamp, and the steel wire rope + basket screw 2-2-2 + protective net is hung on the aluminum alloy tube column 2-2-1 to form a closed guardrail safety system.

[0036] In this embodiment, the aluminum alloy pipe column 2-2-1 is fixed to the truss by an aluminum alloy pipe clamp, exposing more than 1.0m from the top surface of the truss; the φ6mm steel wire rope is hung on the column, arranged at a spacing of 30cm, and tensioned by M8 flower basket bolts; the dense mesh 2-2-3 is hung on the steel wire rope to achieve full closure of the guardrail. Compared with traditional guardrail grilles, the flexible guardrail 2-2 is lighter and has a smaller storage volume. The self-weight of the same specification steel hanging basket given by the traditional hanging basket manufacturer is 300kg, while the self-weight of the aluminum alloy truss hanging basket is only 160kg, with a weight reduction ratio of 47%.

[0037] The present technical solution may also include the following technical details to better achieve the technical effect: it also includes an independent safety wire rope system 4, which includes: a safety anchor 4-1 and an independent wire rope 4-2; the independent wire rope 4-2 is connected by a number of safety anchors 4-1.

[0038] The independent safety wire rope system 4 is an independent wire rope 4-2 installed by personnel near the work point after the main hoist system 1 and the standard truss basket 2 are installed. Its biggest feature is that it is independent of the hanging basket. Even if the hanging basket fails, the safety of personnel can still be guaranteed. Different from the use requirements of traditional hanging baskets, this safety measure is an important item for the acceptance of the hanging basket. It includes a safety anchor 4-1 and an independent wire rope 4-2 that runs the entire length of the cross bridge. The safety anchor 4-1 can be a rebar, an expansion bolt, or a vacuum suction cup with a self-contained vacuum degree inspection. In this project, it is a U-shaped φ16 rebar. If the hanging basket needs to be moved at any time in the glass exterior wall or flat concrete surface working area, it is more convenient to use a vacuum suction cup.

[0039] The technical solution may also include the following technical details to better achieve the technical effect: it also includes auxiliary facilities 5, which include step ladder 5-1, channel guardrail 5-2, cage ladder 5-3 and casters 5-4; in this embodiment, the step ladder 5-1 is used for personnel to climb from the bridge deck to the top of the guardrail, and then climb onto the basket body through the channel guardrail 5-2 and cage ladder 5-3 to work. The casters 5-4 are distributed under the four corners of the truss and have two functions: it is more convenient to shift on flat ground, and it protrudes from the basket body to protect the truss from stone impact when the basket is placed on uneven ground.
