Detailed Description
In order to better understand the technical solution and the concept of the present invention, the following detailed description is made with reference to the specific embodiments and the accompanying drawings.
As shown in fig. 1-3, the lifting appliance comprises a cross beam 1, a movable seat 3 capable of sliding along the length direction of the cross beam is arranged on the cross beam 1, a lifting rope 4 is arranged on the movable seat 3, a connecting part 2 is arranged on the cross beam 1, the connecting part 2 is used for being connected with a lifting device a (shown in the figure) as shown in fig. 4, and the lifting rope 4 is used for being connected with a steel box girder to realize the suspension of the steel box girder B.
The beam 1 is provided with a positioning mechanism which can drive the movable seats 3 to move on the beam 1, each movable seat 3 is respectively provided with a positioning mechanism which can independently adjust the position, and the positioning mechanism can position the movable seats 3 after the movable seats 3 move to the required position. The movable seat 3 can realize positioning at any position in the moving range, so that the function of stepless adjustment of the distance between the lifting ropes is realized.
The scheme of the positioning mechanism for specifically realizing that the movable seat 3 can be positioned at any position in the movable range thereof is specifically described with reference to the following embodiment:
as shown in fig. 1, the positioning mechanism includes a mounting seat 5 fixed on a cross beam 1, a driving member 6 connected to a movable seat 3 is disposed on the mounting seat 5, the driving member 6 in this embodiment is a lead screw, each positioning mechanism is provided with two mounting seats 5 during setting, the two mounting seats 5 are respectively disposed on two sides of the movable seat 3, two ends of the lead screw are movably disposed on the mounting seats 5 and can rotate, the lead screw passes through the movable seat 3 and is in threaded fit with the movable seat 3, the movable seat 3 is driven to move on the cross beam 1 by rotating the lead screw, the lead screw stops rotating after the movable seat 3 moves to a desired position, and at this time, the movable seat 3 is restricted by the lead screw and cannot move when moving, so as to achieve positioning. The screw can be driven to rotate manually or electrically.
