Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a high-safety hanging basket for bridge construction. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapid development of modern transportation, bridges have also been extended to buildings that are built to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; supports are force-transmitting devices installed at the supporting locations between the span structure and the piers or abutments; and ancillary structures include bridgehead slabs, conical slope protection, bank protection, diversion projects, etc.

[0003] During bridge construction, manual work is required on parts of the sides and bottom. During daily use, the sides and areas below the bridge deck also require inspection and maintenance. Therefore, a hanging basket is needed to provide a work platform to carry construction personnel and equipment. A common load-bearing structure is a hanging basket, which is fixed to the edge of the bridge deck at its top and suspended below the deck at the location where construction is required, allowing for the loading of personnel and equipment.

[0004] Current hanging baskets present certain challenges. To access the basket from a bridge, personnel must climb over the bridge guardrail and then step into the basket. If the basket is located at a lower position, they must also climb downward. During this process, environmental influences such as strong winds can cause the basket to sway, posing a safety hazard of a fall. Therefore, a safer hanging basket structure is needed.

The size of the movable frame corresponds to the size of the hanging basket body, so that the movable frame is stacked with the hanging basket body when it slides to the bottom end of the connecting plate. The two ends of the protective net are respectively connected to the bottom of the movable frame and the top of the hanging basket body. The protective net is a semi-enclosed structure so that it can be surrounded by the surface of the connecting plate to form a closed space.

[0008] Furthermore, the mounting portion includes a flat plate and a vertical plate, wherein the vertical plate and the connecting plate are relatively arranged on one side edge of the flat plate, and the hanging basket body is a rectangular frame structure horizontally arranged at the bottom of the connecting plate.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, an embodiment of the present invention provides a highly secure bridge construction hanging basket, comprising a hanging frame, a hanging basket body 3, and a protective device. The hanging frame comprises a mounting portion 1 and a connecting plate 2. The mounting portion 1 is a bent structure, and the connecting plate 2 is vertically fixed to one side bottom edge of the mounting portion 1, so that the mounting portion 1 and the connecting plate 2 together form a bottom-open trough structure. Specifically, the mounting portion 1 comprises a flat plate 11 and a vertical plate 12, wherein the vertical plate 12 and the connecting plate 2 are disposed oppositely at one side edge of the flat plate 11. The hanging basket body 3 is a rectangular frame structure disposed at the bottom end of the connecting plate 2, with the hanging basket body 3 and the hanging basket body 1 located on two opposing surfaces of the connecting plate 2. The connecting plate 2 is also provided with a vertical ladder 21 extending from the top of the connecting plate 2 to the interior of the hanging basket body 3 at the bottom. This allows workers to move downward from the top of the connecting plate 2 into the hanging basket body 3 via the ladder 21 to perform construction work.

[0022] The protective device includes a movable frame 4 and a protective net 5. The movable frame 4 is slidably mounted on the side surface of the connecting plate 2 corresponding to the hanging basket body 3, allowing it to slide vertically. The size of the movable frame 4 corresponds to the size of the hanging basket body 3, so that when the movable frame 4 slides to the bottom of the connecting plate 2, it overlaps the hanging basket body 3. The ends of the protective net 5 are respectively connected to the bottom of the movable frame 4 and the top of the hanging basket body 3. The protective net 5 has a semi-enclosed structure, allowing it to surround the surface of the connecting plate 2 to form an enclosed space. That is, when people go up and down, the movable frame 4 is located on the top of the connecting plate 2, and the protective net 5 is unfolded to form an enclosed protective structure. When people are working, the movable frame 4 can be moved to the bottom to overlap with the hanging basket body, and the protective net 5 is folded and does not affect the construction work. Therefore, when environmental factors cause the hanging basket body 3 to shake, the protective net 5 can protect the workers inside and prevent them from falling during the climbing process, thereby improving safety.

[0023] like Figure 2 As shown, in this embodiment, the connecting plate 2 is symmetrically provided with slide rails 6 on both side edges of the surface where the hanging basket body 3 is located. The slide rail 6 is a hollow structure, and an opening connected to the outside is opened in the middle of the outer side. A pulley 7 is provided inside the slide rail 6. The pulley 7 is movably connected to the inner wall of the slide rail 6 through a roller 71, so that the pulley 7 can move in the vertical direction along the slide rail 6. The pulley 7 is also provided with a support rod 72, and the support rod 72 passes through the opening and is fixedly connected to the movable frame 4. It should be noted that a driving device is also provided between the slide rail 6 and the pulley 7. In this embodiment, an electric hoist is used to lift the pulley 7, thereby driving the pulley 7 and the movable frame 4 as a whole to move in the vertical direction.

[0024] In a preferred embodiment, the pulley 7 is provided with two sets of horizontally symmetrical rollers 71, one on each side of the front and rear inner walls of the slide rail 6, to ensure close contact between the pulley 7 and the inner wall of the slide rail 6. Because the movable frame 4 is located to one side of the pulley 7, it constantly applies a pulling force to the pulley 7 toward the inner wall of the slide rail 6. Therefore, the rollers 71 on the pulley 7 are provided in contact with the inner wall of the slide rail 6, making the pulley 7 move more smoothly and less likely to get stuck.

[0025] like Figure 3As shown, preferably, the ladder 21 is arranged in an area near the side of the surface of the connecting plate 2, and a horizontal support plate 22 is provided at a position below the top of the connecting plate 2, and the support plates 22 are arranged side by side on one side of the ladder 21. The support rod allows the staff to first climb over the connecting plate 2 and stand on the side of the ladder 21, turn around on the spot, and then move horizontally to the ladder 21, instead of having to turn around and stand on the ladder 21 as soon as they climb over the connecting plate 2, which further improves convenience and safety. In addition, the area on the inner side of the connecting plate 2 corresponding to the ladder 21 is hollowed out for easy stepping during use. There are also handrails 23 extending upward on both sides of the top of the connecting plate 2 to facilitate steadying when climbing from the top.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
