Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipeline engineering construction, and particularly relates to a steel hanger for hoisting large-diameter reinforced concrete drainage pipelines. Background Technique

[0002] The drainage pipeline project is a pipeline system project for collecting, transporting and discharging industrial wastewater, domestic sewage and rainwater. The drainage pipeline project is an inalienable part of the drainage system and plays an important role in the entire drainage system. It includes the pipeline system itself and various structure projects on the pipeline system. Drainage pipelines include main drainage pipes, trunk pipes, branch pipes, inspection wells and connecting wells, etc. In order to meet the urban drainage requirements, when planning and designing the urban comprehensive drainage system, the burial depth of the main drainage pipes and trunk pipes is getting deeper and deeper, and the use of large-diameter pipes is increasing, resulting in large hoisting distances and the hoisting weight of a single-section pipeline. In actual construction, the previous wire rope hoisting process is prone to problems such as insecure hoisting fixation, damage to the pipe orifice, and inaccurate pipe docking. Therefore, it is necessary to design a steel hanger for hoisting large-diameter reinforced concrete drainage pipelines to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a steel hanger for hoisting large-diameter reinforced concrete drainage pipelines. This device solves the problems of insecure hoisting fixation, damage to the pipe orifice, and inaccurate pipe docking of large-diameter reinforced concrete drainage pipelines in the prior art, and has the characteristics of improving the stability, safety and convenience of hoisting operations.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a steel hanger for hoisting large-diameter reinforced concrete drainage pipelines, including a lifting ring and a steel hanger. The lifting ring includes two lifting rings and an auxiliary lifting ring. The steel hanger includes an upper lifting arm. One end of the upper lifting arm is connected to the top end of a vertical connecting arm, and the bottom end of the connecting arm is connected to one end of a horizontally arranged supporting arm; the lifting rings and the auxiliary lifting ring are fixedly connected to the upper lifting arm.

[0005] Preferably, a bolt hole is provided at one end of the supporting arm.

[0006] Preferably, the bolt hole is in threaded cooperation with a limiting device. The limiting device includes a limiting block, and the limiting block is threadedly connected to the bolt hole at the end of the supporting arm through a fixing bolt.

[0007] Preferably, the two lifting rings are respectively fixedly connected to both ends of the upper lifting arm, and the auxiliary lifting ring is fixedly connected to the middle position of the upper lifting arm.

[0008] Further, the upper lifting arm, the connecting arm and the supporting arm are fixedly connected into an integral U-shaped hanger.

[0009] The beneficial effects of a steel hanger for hoisting large-diameter reinforced concrete drainage pipes provided by the present utility model are as follows:

[0010] This device adopts a lifting ring, a steel hanger, and a limiting device, solving the problems of unstable hoisting and fixing, pipe nozzle damage, and inaccurate pipe butt joint of large-diameter reinforced concrete drainage pipes, and improving the stability, safety, and convenience of hoisting operations.

[0013] Figure 2 is a schematic diagram of the reinforcement of the lifting ring in the embodiment of the present utility model;

[0014] In the figure: lifting ring 1, auxiliary lifting ring 2, upper lifting arm 3, connecting arm 4, supporting arm 5, limiting block 6. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Embodiment 1:

[0016] As shown in Figure 1 , a steel hanger for hoisting large-diameter reinforced concrete drainage pipes includes a lifting ring and a steel hanger. The lifting ring includes two lifting rings 1 and an auxiliary lifting ring 2. The steel hanger includes an upper lifting arm 3. One end of the upper lifting arm 3 is connected to the top end of the vertical connecting arm 4, and the bottom end of the connecting arm 4 is connected to one end of the horizontally arranged supporting arm 5; the lifting ring 1 and the auxiliary lifting ring 2 are fixedly connected to the upper lifting arm 3.

[0017] Preferably, one end of the supporting arm 5 is provided with a bolt hole.

[0018] Preferably, the bolt hole is in threaded fit with the limiting device. The limiting device includes a limiting block 6, and the limiting block 6 is threadedly connected to the bolt hole at the end of the supporting arm 5 through a fixing bolt.

[0019] Preferably, the two lifting rings 1 are respectively fixedly connected to both ends of the upper lifting arm 3, and the auxiliary lifting ring 2 is fixedly connected to the middle position of the upper lifting arm 3.

[0020] Furthermore, the upper lifting arm 3, the connecting arm 4, and the supporting arm 5 are fixedly connected into an integral U-shaped hanger.

[0021] Embodiment 2:

[0022] The hanger in this application is used to hoist reinforced concrete pipes with a pipe diameter of 1000 mm to 2600 mm and a single-section length of 2.5 m, 3 m, and 3.5 m. The pipes are connected by socket or tongue-and-groove joints. The specific working principle is as follows:

[0023] During use, the lifting ring 1 is connected to the crane hook through a steel wire rope, and the length of the steel wire rope can be adjusted to ensure that the supporting arm 5 of the steel section hanger remains horizontal. When lifting, insert the supporting arm 5 of the steel section hanger into the pipeline, and install the limit block 6 to avoid the risk of the pipeline slipping during the lifting process. After lifting to the installation operation surface, when the pipeline is lowered to a safe height, manually remove the limit block 6. Manually assist in connecting the lifted pipeline to the adjacent pipeline to complete the connection.

[0024] As Figure 2 shown in the figure, in order to ensure the safety of use, the lifting ring 1 can be reinforced. A conical steel plate is welded to the bottom of the lifting ring, and the steel plate is perpendicular to the plane of the lifting ring, so as to avoid the bending of the lifting ring 1. The upper lifting arm 3 below adopts a hollow structure, which can reduce the overall weight of the device and achieve lightweight under the premise of ensuring strength as much as possible.
