Description

Technical Field

[0001] The utility model relates to the technical field of hoists, in particular to a hoist for preventing deformation of steel plate shear walls. Background Art

[0002] The use of steel structures in large new public buildings is a major development direction in the current construction industry. Among them, steel plate shear walls are becoming more and more widely used due to their good seismic performance, strong structural stability, simple construction and good economy.

[0003] Before installing the steel plate shear wall, it needs to be hoisted from the unloading truck to the steel plate shear wall yard by a crane and wait for installation. Since there are multiple bolts evenly distributed on the wall surface of the steel plate shear wall, the hoisting measures generally use multiple steel plate clamps to clamp several edge points on the steel plate shear wall, and then hoist it. Multiple steel plate clamps as hoists cause the stress points of the components to be mainly at the edges of the components, so that the middle part of the components is easily deformed, which poses a quality risk. Utility Model Content

[0004] In view of the above problems in the prior art, the utility model provides a hoisting and anti-deformation hoist for steel plate shear walls, which solves the problem that steel plate shear walls are easily deformed during the hoisting process.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] Provided is a hoist for preventing deformation of steel plate shear walls during hoisting, comprising: a hoist frame, which is a frame structure with a hollow interior, and a plurality of reserved holes for passing bolts on the steel plate shear wall are provided on the bottom surface of the hoist frame, and each of the reserved holes is cam-shaped; a sliding baffle, which is placed on the inner bottom surface of the hoist frame, and a plurality of L-shaped clamping holes are provided on the sliding baffle, and the clamping holes include round holes for passing bolts and clamping slot holes for clamping the bolts; a twisting clamp rod, which is rotatably arranged on the sliding baffle and is used to fix the sliding baffle and the hoist frame, and a locking rod is provided on the torsion rod of the twisting clamp rod, and a locking groove clamped with the locking rod is provided on the hoist frame.

[0007] The working principle of this scheme is to place the hanger frame on the steel plate shear wall, and pass the heads of multiple bolts on the steel plate shear wall through the large diameter ends of multiple reserved holes on the hanger frame and the round holes of multiple clamping holes on the sliding block plate in turn, then push the hanger frame and move each bolt to the small diameter end on the corresponding reserved hole, then push the sliding block plate and move each bolt to the corresponding clamping slot hole, and rotate and twist the clamping rod to drive the locking rod into the locking slot to fix the sliding block plate and the hanger frame, limit the relative displacement of the sliding block plate and the hanger frame, so that each bolt is fixed in the clamping slot hole of the clamping hole and the small diameter end of the reserved hole at the same time, so that when the hanger frame is lifted, the force points of the hanging steel plate shear wall are distributed on each bolt on the end face, so that compared with the steel plate clamp, this scheme makes the force of the hanging steel plate shear wall more uniform, and the steel plate shear wall is not easy to deform during the lifting process.

[0008] Furthermore, the sling frame comprises an upper plate and a lower plate which are in a cross shape when projected from above, and the side edges of the upper plate and the lower plate are fixedly connected by a plurality of spaced connection plates.

[0009] Furthermore, the center and four ends of the bottom surface of the upper plate and the top surface of the lower plate are fixedly connected by at least two connecting rods.

[0010] Furthermore, a lifting lug is provided in the middle of the upper plate, and the provision of the lifting lug is convenient for lifting the hook.

Setting the diameters of the large diameter end and the small diameter end of the reserved hole in this way ensures that the head of the bolt can enter the reserved hole, while enabling the small diameter end of the reserved hole to limit the freedom of movement of the bolt.

[0012] Further, the sliding resistance plate is a cross-shaped plate, and the width of the opposite sides of the sliding resistance plate is smaller than the width of the opposite sides of the lower plate. The width of the sliding resistance plate is set in this way, so that the sliding resistance plate can be moved in the spreader frame.

[0013] Furthermore, the plurality of clamping holes on the sliding block plate are in a one-to-one correspondence with the plurality of reserved holes, the clamping slot of each clamping hole is rectangular, and the central axis of the clamping slot is perpendicular to the central axis of the corresponding reserved hole. The positions of the clamping slot and the reserved hole are arranged in this way so that the small diameter ends of the clamping slot and the reserved hole can better limit the lateral and longitudinal displacement of the bolt.

[0014] Furthermore, the width of the slot hole is equal to the nominal diameter of the bolt. By setting the width of the slot hole in this way, the slot hole can better limit the freedom of the bolt.

[0015] Furthermore, the torsion clamping rod also includes a U-shaped circular plate, which is welded on the sliding block plate and the central axis of the U-shaped circular plate is parallel to the central axis of the clamping slot hole. One end of the torsion rod passes through the U-shaped circular plate and is fixedly connected to the limit cap. A locking rod is vertically arranged at the middle of the torsion rod, and a handle rod is arranged on the other end of the torsion rod. The length of the handle rod is greater than the length of the locking rod. The direction of the U-shaped circular plate is arranged in this way so that the force direction of the locking rod is the same as the moving direction of the sliding block plate, so that the locking rod can better lock the sliding block plate and the sling frame.

Setting the diameters of the large diameter end and the small diameter end of the reserved hole 1.6 in this way ensures that the head of the bolt can enter the reserved hole 1.6, while allowing the small diameter end of the reserved hole 1.6 to limit the freedom of movement of the bolt.

[0035] refer to Figure 3 and Figure 5 The sliding baffle plate 2 is placed on the inner bottom surface of the sling frame 1. The sliding baffle plate 2 is provided with a plurality of L-shaped clamping holes 2.1. The clamping holes 2.1 include round holes for bolts to pass through and clamping slot holes for clamping the bolts.

[0036] The multiple clamping holes 2.1 on the sliding block 2 are in a one-to-one correspondence with the multiple reserved holes 1.6. The clamping slot of each clamping hole 2.1 is rectangular, and the central axis of the clamping slot is perpendicular to the central axis of the corresponding reserved hole 1.6. The positions of the clamping slot and the reserved hole 1.6 are set in this way, so that the small diameter ends of the clamping slot and the reserved hole 1.6 can better limit the lateral and longitudinal displacement of the bolt. The width of the clamping slot is equal to the nominal diameter of the bolt. The width of the clamping slot is set in this way, so that the clamping slot can better limit the freedom of the bolt.

[0037] refer to Figure 6 , the twisting card rod 3 is rotatably set on the sliding resistance plate 2 and is used to fix the sliding resistance plate 2 and the sling frame 1. A locking rod 3.2 is set on the torsion rod 3.3 of the twisting card rod 3, and the sling frame 1 is provided with a locking groove 1.7 that is clamped with the locking rod 3.2.

[0038] In this embodiment, each bolt on the steel plate shear wall can be fixed in the slot hole of the clamping hole 2.1 and the small diameter end of the reserved hole 1.6 at the same time, so that when the lifting device frame 1 is lifted, the force points of the steel plate shear wall are distributed on each bolt on the end surface.

[0039] As a specific structure of the spreader frame 1, the spreader frame 1 includes an upper plate 1.1 and a lower plate 1.2 which are in a cross shape when viewed from above, and the side edges of the upper plate 1.1 and the lower plate 1.2 are welded by a plurality of spaced connection plates 1.4.

[0042] As a specific structure of the sliding resistance plate 2, the sliding resistance plate 2 is a cross-shaped plate, and the width of the opposite sides of the sliding resistance plate 2 is smaller than the width of the opposite sides of the lower plate 1.2. The width of the sliding resistance plate 2 is set in this way, so that the sliding resistance plate 2 can move in the hanger frame 1.

[0043] As a specific structure of the twisting clamping rod 3, the twisting clamping rod 3 also includes a U-shaped circular plate 3.4, which is welded on the sliding block plate 2 and the central axis of the U-shaped circular plate 3.4 is parallel to the central axis of the clamping slot hole. The direction of the U-shaped circular plate 3.4 is set in such a way that the force direction of the locking rod 3.2 is the same as the moving direction of the sliding block plate 2, so that the locking rod 3.2 can better lock the sliding block plate 2 and the sling frame 1.
