Embodiment Construction

[0039] The following is attached Figure 1-5 The application is described in further detail.

[0040] On the one hand, the embodiment of the present application discloses a bridge crane construction hoisting system, refer to figure 1 , including a support assembly and a traction assembly, the support assembly serves as a fulcrum, and the components of the crane can be hoisted by the traction assembly.

[0041] The support assembly includes a support frame 2, the support frame 2 includes a lifting point anchor plate 21 and a leg 22 connected with the lifting point anchor plate 21, one end of the leg 22 is hinged with the lifting point anchor plate 21, and the number of legs 22 is at least three group, the number of supporting legs 22 in this embodiment is four groups, so that it is difficult to topple over during the hoisting process.

[0042] One end of the support leg 22 far away from the anchor plate 21 of the lifting point has a support seat 23, and the support seat 23 is...

Abstract

The invention relates to a bridge crane installation construction method, and belongs to the field of road and bridge construction methods. The bridge crane installation construction method comprises the following steps: (1) conducting construction preparation and hoisting system stress checking calculation; (2) installing a hoisting system; (3) disassembling a bridge crane into five parts of a main beam, a trolley frame, a main lifting device and an auxiliary lifting device; (4) hoisting the main beam by means of the hoisting system; and (5) hoisting the other parts of the bridge crane by means of the hoisting system; The hoisting system comprises a supporting assembly and a traction assembly, the supporting assembly comprises a supporting frame, the supporting frame comprises a hoisting point anchoring plate and supporting legs connected with the hoisting point anchoring plate, the traction assembly comprises a pulley block and a traction rope arranged on the pulley block in a penetrating mode, one end of the traction rope is connected with a clamping assembly used for being connected with a crane component, and the other end of the traction rope is used for being connected with a winch. The bridge crane installation construction method has the effect of improving the construction efficiency of installation of the bridge crane in a narrow tunnel.

Description

technical field [0001] The present application relates to the field of road and bridge construction methods, in particular to a construction method for installing a bridge crane. Background technique [0002] In water conservancy and hydropower projects, bridge cranes are widely used as important lifting equipment for the installation of mechanical equipment such as generator sets and working gates. The space for lifting materials is not hindered by ground equipment. [0003] At present, during the construction of narrow tunnels, due to the inaccessibility of large lifting equipment, the traditional construction method of installing bridge cranes is to drill holes on the top of the tunnel in advance, construct long anchor rods, and use pulley blocks to hoist the bridge cranes as stress points. . [0004] With regard to the related technologies mentioned above, the inventor believes that there is a defect that a large number of drilling holes leads to a long construction ti...
