Description

Technical Field

[0001] The utility model relates to the technical field of steel anchor boxes for lifting steel box girders of steel structures, in particular to an integrated steel anchor box for lifting and aligning steel box girders. Background Art

[0002] When the existing steel box girder is lifted, the steel anchor box is directly welded on the steel box girder to be lifted. When the steel box girder is lifted to the designed height for alignment, the lifting wire rope is fixed relative to the lifting point of the steel box girder and cannot play a role in the alignment of the steel box girder. The alignment of the steel box girder can only be achieved by welding an alignment code plate between the steel box girder and the cantilever beam connected thereto, and then the alignment of the steel box girder is achieved by pushing and pulling the alignment code plate through a push-pull hydraulic cylinder. Therefore, the alignment operation of the steel box girder has a large workload, low operating efficiency, and long operating time. During the lifting and alignment process of the steel box girder, its lifting support system is a temporary support structure. The lifting and alignment of the steel box girder is a high-risk operation. The long alignment operation time has a serious adverse effect on the safety of the construction process. Therefore, how to reduce the workload of the steel box girder alignment operation, shorten the operation time, and improve the operation efficiency is of great significance to improving the safety of the lifting and alignment operations of the steel box girder. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model discloses an integrated steel anchor box which can reduce the workload of lifting and aligning the steel box girder. When the integrated steel anchor box is used to lift and align the steel box girder, there is no need to weld the alignment code plate, and the integrated steel anchor box can be used directly to align the steel box girder, thereby significantly shortening the operation time and improving the operation efficiency.

[0004] In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: an integrated steel anchor box for lifting and aligning a steel box girder, comprising a hoisting box and a hydraulic cylinder for adjusting the position, wherein the hydraulic cylinder for adjusting the position is hingedly arranged on the side of the hoisting box; when the integrated steel anchor box is used, the steel box girder lifting wire rope is fixedly connected to the hoisting box, and the hoisting box and the hydraulic cylinder for adjusting the position are hingedly connected to the steel box girder to be lifted; the principle of the integrated steel anchor box to achieve the alignment of the steel box girder is shown in the attached manual. Figure 7 , 8When the integrated steel anchor box lifts the steel box girder, it is hinged at both ends of the upper part of the steel box girder. If the steel box girder needs to be translated to the right, the alignment adjustment hydraulic cylinder of the rightmost integrated steel anchor box is extended to drive the hoisting box to rotate around the hinge axis. When the lifting wire rope changes from a vertical state to an inclined state, the inclined wire rope will generate a horizontal component force F to the right, and the horizontal component force F to the right will drive the steel box girder to move to the right, thereby adjusting the aerial position of the steel box girder and achieving alignment; by controlling the corresponding action of the alignment adjustment hydraulic cylinder of the integrated steel anchor box, the steel box girder can be horizontally rotated, horizontally translated, and vertically translated. Therefore, the alignment adjustment of the steel box girder is convenient and flexible. At the same time, there is no need to set up alignment code plates and push-pull hydraulic cylinders during high-altitude construction, which greatly shortens the operation time and improves the alignment efficiency of the steel box girder.

[0005] Furthermore, the hanging box includes a hanging frame, a wire rope fixing head, and a fixing head pressure plate; the hanging frame includes a hanging frame side plate, a hanging box top plate, and a wire rope fixing plate, and the two hanging frame side plates are arranged in parallel and are welded and connected through the hanging box top plate and the wire rope fixing plate; a conical fixing head locking hole is provided in the middle of the wire rope fixing plate, and two semicircular wire rope fixing heads are movably arranged in the fixing head locking hole; the fixing head pressure plate is arranged at the lower part of the wire rope fixing plate and is connected to the wire rope fixing plate by bolts; the upper surface of the fixing head pressure plate conflicts with the lower end surface of the wire rope fixing head; see the attached manual Figure 4 When the hoisting box is fixedly connected to the wire rope, the lower end of the wire rope passes through the top plate, the wire rope fixing head, and the fixing head pressure plate in sequence. When the connecting bolts between the fixing head pressure plate and the wire rope fixing plate are locked, the fixing head pressure plate moves upward, pushing the two semicircular wire rope fixing heads to move upward, and the outer conical surface of the wire rope fixing head cooperates with the tapered hole of the wire rope fixing plate, so that the two semicircular wire rope fixing heads lock the wire rope, thereby realizing the fixed connection between the wire rope and the hoisting box.

[0006] Furthermore, a hydraulic cylinder hinge ear is fixedly provided on the side of the hanging frame side plate, and the positioning adjustment hydraulic cylinder is hingedly connected to the hydraulic cylinder hinge ear.

[0007] Furthermore, a side plate hinge hole is provided at the lower part of the side plate of the hanging frame. When the steel anchor box is in use, the hanging box is hingedly connected to the steel box girder to be lifted through the side plate hinge hole.

[0008] Furthermore, the positioning adjustment hydraulic cylinder includes a cylinder liner and a piston rod. The tail of the cylinder liner and the head of the piston rod are both provided with hinge holes. The tail of the cylinder liner or the head of the piston rod is hingedly connected to the hinge ear of the hydraulic cylinder through the hinge hole. When the steel anchor box is in use, the head of the piston rod or the tail of the cylinder liner is hingedly connected to the steel box girder to be lifted through the hinge hole.

[0009] Furthermore, the wire rope fixing head is semicircular, and the outer circumference is provided with an outer conical surface of the fixing head matching the locking hole of the fixing head, a wire rope hole is provided in the middle, and a fixing head R angle is provided at the small end of the wire rope hole; when the hoisting box rotates around the hinge axis between the steel box girder under the drive of the alignment adjustment hydraulic cylinder, the wire rope changes from a vertical state to an inclined state. At this time, the wire rope contacts the upper edge of the wire rope hole of the wire rope fixing head. When the upper edge of the wire rope hole is a sharp edge, the stress at the contact point is extremely large, which will damage the wire rope; when the fixing head R angle is set on the upper edge of the wire rope hole of the wire rope fixing head, the stress at the contact point is greatly reduced, thereby avoiding damage to the wire rope.

[0010] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects: the utility model discloses an integrated steel anchor box for lifting and aligning a steel box girder, comprising a hoisting box and a positioning adjustment hydraulic cylinder, wherein the positioning adjustment hydraulic cylinder is hingedly arranged on the side of the hoisting box; when the integrated steel anchor box is in use, the steel box girder lifting wire rope is fixedly connected to the hoisting box, and the hoisting box and the positioning adjustment hydraulic cylinder are hingedly connected to the steel box girder to be lifted; when adjusting the alignment of the steel box girder, the positioning adjustment hydraulic cylinder of the integrated steel anchor box is extended to drive the hoisting box to rotate around the hinge axis, and the lifting wire rope changes from a vertical state to an inclined state, and the inclined wire rope will generate a horizontal component force, and the horizontal component force will drive the steel box girder to move, thereby realizing the adjustment of the aerial position of the steel box girder and realizing alignment, so the alignment adjustment of the steel box girder is convenient and flexible, and at the same time, there is no need to set up alignment code plates and push-pull hydraulic cylinders during high-altitude construction, which greatly shortens the operation time and improves the alignment operation efficiency of the steel box girder.
