The utility model comprises the following steps:
the utility model aims to provide a steel reinforcement framework hoisting device for bridge construction, overcomes the defects of the prior art, and effectively solves the existing problems in the steel reinforcement framework hoisting process.
The utility model comprises the following steps: the utility model provides a framework of steel lifting device for bridge construction, includes triangle-shaped truss be provided with the cantilever between triangle-shaped truss's the upper chord member and the lower chord member, the cantilever with triangle-shaped truss's lower chord member passes through fastener fixed connection the both ends of cantilever all are provided with adjustable lifting hook subassembly.
Further, the adjustable hook assembly comprises a steel sleeve, the steel sleeve is sleeved on the cantilever, the steel sleeve is in sliding connection with the cantilever, and a hook is installed at the bottom end of the steel sleeve.
Further, a first screw hole is formed in the top end of the steel sleeve, and a jackscrew is screwed in the first screw hole.
Further, the lifting hook is an inverted T-shaped lifting hook.
Furthermore, the two ends of the cantilever are provided with anti-drop caps.
Further, the fastening piece comprises cap-shaped steel, the cap-shaped steel is buckled on the cantilever, and two ends of the cap-shaped steel are fixedly connected with the lower chord of the triangular truss through first bolts.
Further, flange plates are arranged at two ends of the upper chord member and the lower chord member of the triangular truss.
Further, lifting lugs are arranged on the upper chord members of the triangular trusses.
The utility model has the beneficial effects that: the lifting stress points of the steel reinforcement framework are more uniform through the adjustable lifting hook component, deformation and inclination phenomena are not easy to occur in the lifting process, and the triangular truss and the cantilever are rapidly installed and detached through the fastening piece, so that the lifting appliance is more convenient and rapid to use and transport.
Description of the drawings:
FIG. 1 is a front view of the present utility model;
FIG. 2 is a partial cross-sectional view of a front view of the present utility model;
FIG. 3 is a cross-sectional view of section A-A of FIG. 1;
FIG. 4 is a cross-sectional view of portion B-B of FIG. 1;
in the figure, a triangle truss 1, a cantilever 2, a steel sleeve 3, a lifting hook 4, a jackscrew 5, an anti-drop cap 6, cap-shaped steel 7, a first bolt 8, a flange 9 and a lifting lug 10.
The specific embodiment is as follows:
for a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings:
as shown in fig. 1 to 4, a steel reinforcement cage hoisting device for bridge construction comprises a triangular truss 1, wherein a cantilever 2 is arranged between an upper chord member and a lower chord member of the triangular truss 1, the cantilever 2 is fixedly connected with the lower chord member of the triangular truss 1 through fastening pieces, adjustable hook assemblies are arranged at two ends of the cantilever 2, each adjustable hook assembly comprises a steel sleeve 3, the steel sleeves 3 are sleeved on the cantilever 2, the steel sleeves 3 are in sliding connection with the cantilever 2, a lifting hook 4 is arranged at the bottom end of the steel sleeves 3, a first screw hole is formed in the top end of the steel sleeve 3, a jackscrew 5 is in the first screw hole in a screwed manner, the lifting hook 4 is an inverted-T-shaped lifting hook, and anti-drop caps 6 are arranged at two ends of the cantilever 2.
Specifically, the lifting stress points of the steel reinforcement framework are more uniform through the adjustable lifting hook component, and deformation and inclination phenomena are not easy to occur in the lifting process.
In the actual use process, the position of the steel sleeve 3 on the cantilever 2 is adjusted according to the actual size of the field reinforcement cage, and the jackscrew 5 is screwed after the position adjustment is finished, so that the steel sleeve 3 is prevented from displacement in the hoisting process; the inverted T-shaped lifting hook 4 can be more uniformly distributed on the steel reinforcement framework by using a plurality of lifting ropes, so that the multi-lifting-point lifting operation of the steel reinforcement cage is realized.
As shown in fig. 1 to 4, the fastening member comprises a hat-shaped steel 7, the hat-shaped steel 7 is fastened on the cantilever 2, two ends of the hat-shaped steel 7 are fixedly connected with the lower chord of the triangular truss 1 through first bolts 8, flange plates 9 are installed at two ends of the upper chord and the lower chord of the triangular truss 1, and lifting lugs 10 are installed on the upper chord of the triangular truss 1.
Specifically, the cantilever 2 and the triangular truss 1 are more convenient to install and detach through the cap-shaped steel 7, and the transportation of the later lifting appliance is facilitated.
In the actual use process, the cap-shaped steel 7 is buckled on the cantilever 2 and is fixed with the lower chord of the triangular truss 1 by using the first bolt 8, the first bolt 8 is detached after hoisting is finished, and the cap-shaped steel 7 is taken off, so that the cantilever 2 and the triangular truss 1 are quickly fixed and detached; if the length of the on-site reinforcement cage is longer, the multi-section triangular truss 1 can be assembled in a butt joint way through the flange plate 9, so that the normal hoisting of the reinforcement cage is ensured.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
