Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline construction technical field more specifically, relate to a kind of turnover pipeline hoisting device for comprehensive pipe gallery. BACKGROUND

[0002] Single-bin comprehensive pipe gallery is an important carrier for intensive laying of urban underground pipelines, and the main structure thereof is usually limited to a width of 3-5 meters, and the internal net height is generally less than 3 meters. In such a limited space, when multiple large-diameter pipelines such as water supply, heating and gas pipelines need to be laid, the pipeline arrangement density can reach 0.8-1.2 pipelines per meter. Due to the pre-installation of a large number of steel structure supports and cable bridge systems inside the pipe gallery, the actual operation space is further limited, and the minimum operation radius of conventional construction machinery such as pipeline installation hoists and other auxiliary equipment is required to be 1.5 meters, so that the construction cannot be carried out.

[0003] The current construction method mainly uses a pre-buried or post-positioned hoisting system: the former pre-buries cast iron lifting rings during the construction of the main structure, and the latter fixes temporary lifting points by drilling and expanding bolts in the cast-in-place roof. Both methods have significant defects: the pre-buried lifting rings need to be accurately positioned during the construction of the structure, and in actual construction, more than 30% of the pre-buried points are often invalid due to adjustment of the pipeline arrangement scheme; the post-positioned expansion bolt installation is time-consuming and has the risk of local damage to the concrete structure. UTILITY MODEL CONTENT

[0004] To overcome the above-mentioned deficiencies in the prior art, the utility model provides a turnover pipeline hoisting device for comprehensive pipe gallery. The device can be temporarily stressed on the pipeline support, and then the pipeline installation is carried out, without the need for pre-buried lifting rings or post-installation of lifting rings during pipeline installation. After the pipeline is installed and fixed, the hoisting device is removed for reuse, which has the advantages of simple production, flexible installation and strong practicality.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A turnover pipeline hoisting device for comprehensive pipe gallery, which is installed and erected on the top of the comprehensive pipe gallery, comprises a support frame, a limiting cross beam, a wing plate, a clamping limiting bolt and a pipeline lifting tool. The support frame is a rectangular frame with an open bottom. The limiting cross beam is arranged inside the support frame, and the limiting cross beam is arranged vertically to the side plates of the support frame. Two wing plates are arranged on the top of the support frame and face two sides respectively. Holes are formed in the two side edges of the support frame. The clamping limiting bolt is arranged in the support frame through the holes. The clamping limiting bolt is arranged below the limiting cross beam and parallel to the limiting cross beam. Connection holes are formed in the wing plate, and the pipeline lifting tool is connected to the wing plate through the connection holes.

[0007] The wing plate is provided with a reinforcing rib plate, and the bottom of the reinforcing rib plate is welded and fixed with the side plate of the support frame body.

[0008] The reinforcing rib plate is vertically arranged with the wing plate.

[0009] The wing plate is arranged obliquely on the support frame body.

[0010] An inner gasket layer is arranged on the bottom of the limiting cross beam and the inner side wall of the support frame body, and the inner gasket layer is made of wear-resistant rubber material.

[0011] Position adjusting strip-shaped holes are formed in the two side plates of the support frame body, and the clamping limiting bolts are arranged to penetrate through the position adjusting strip-shaped holes.

[0012] The support frame body is made of flat steel by welding.

[0013] The pipeline lifting tool is an electric hoist or a hand-operated hoist.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The vertical arrangement of the support frame body and the limiting cross beam forms a rigid frame structure, and the two-way clamping design of the clamping limiting bolts significantly improves the overall stability of the device. The oblique arrangement of the wing plate at an angle of 45° in combination with the vertical welding structure of the reinforcing rib plate further enhances the carrying capacity and the bending strength; the position adjusting strip-shaped holes arranged on the two sides of the support frame body and the clamping limiting bolts form an adjustable clamping system, and through the flexible adjustment of the position of the bolts, the device can be adapted to comprehensive pipe gallery cross beams of different width specifications, realizes "one machine with multiple uses", and reduces the repeated purchase cost of equipment; the open bottom support frame body design does not require complex pre-embedded parts or welding procedures, and the installation of the frame body can be quickly completed through the synergistic effect of the limiting cross beam and the clamping bolt. The wear-resistant rubber inner gasket layer not only improves the friction coefficient to ensure the installation stability, but also avoids the wear caused by the direct contact of metal components; the device is made of standard flat steel by welding, has a lightweight structure and high strength redundancy, and supports repeated turnover use. Compared with the traditional scaffold erection method, the device can reduce the consumption of auxiliary materials, significantly shorten the construction period, and meet the green construction concept.
