[0039] Example 1

[0040] Reference Figure 1 As shown, this embodiment provides a steel cage fixing support device, which includes a base 1 and a plurality of support frames 2. A vertical through groove 11 for accommodating the steel cage 300 passing through is provided on the base 1, and the base 1 is placed on the top of the pile hole of the pile foundation, and the vertical through groove 11 is arranged coaxially with the pile hole.

[0041] Specifically, the support frame 2 includes a fixed frame 21, a movable support leg 22 and a limiter 23. The fixed frame 21 is connected to the base 1, and the structure of the fixed frame 21 is a gate-shaped structure, and a horizontal through slot is provided on the fixed frame 21. The movable support leg 22 passes through the horizontal through slot and is movably connected to the fixed frame 21 along the axial direction of the horizontal through slot. By moving the movable support leg 22 along the axial direction of the horizontal through slot, the steel cage 300 can be supported or the steel cage 300 can be further lowered. The movable support leg 22 includes a support end, and the support end extends to the vertical through slot 11; refer to Figure 2 As shown, a hollow cavity 24 is provided in the movable support foot 22, and the limiting member 23 includes a connecting plate 25, a limiting plate 26 and a threaded rod 27; the connecting plate 25 is placed in the cavity 24, the limiting plate 26 is connected to the connecting plate 25 and is placed on the outside of the supporting end, the threaded rod 27 is connected to the connecting plate 25 and is connected to a first nut 28 after passing through the movable support foot 22; when the connecting plate 25 is in contact with the top of the cavity 24, the limiting plate 26 extends above the top of the movable support foot 22 to limit the stirrups of the steel cage 300.

[0042] When the steel cage 300 needs to be fixed, the first nut 28 is screwed to move the limiter 23 upward until the height of the limiter plate 26 exceeds the movable support leg 22, and the limiter plate 26 abuts against the inner wall of the stirrups on the steel cage 300. The limiter plates 26 of multiple support frames 2 abut against the inner wall of the stirrups at the same time, thereby horizontally limiting the steel cage 300. By adjusting the horizontal position of the movable support leg 22, steel cages 300 of different diameters can be fixed. When the steel cage 300 needs to be further lowered, the second nut 82 is screwed to move the limiter 23 downward until the height of the limiter plate 26 does not exceed the movable support leg 22. At this time, it is convenient to horizontally move the movable support leg 22 so that the movable support leg 22 is separated from the steel cage 300, which is convenient for the steel cage 300 to continue to be lowered.

[0043] The present embodiment provides a steel cage fixing support device, which can fix steel cages 300 of different diameters by changing the horizontal position of the movable support legs 22 in conjunction with the limit plates 26. Changing the height of the limit plates 26 can facilitate the separation of the movable support legs 22 from the steel cage 300 and the continued lowering of the steel cage 300, and has a wide range of applications.

[0044] Specifically, a threaded through hole is provided on the top of the fixing frame 21; a locking screw 29 is connected in the threaded through hole, and when the locking screw 29 abuts against the movable support leg 22, the horizontal movement of the movable support leg 22 is limited. The horizontal movement of the movable support leg 22 is limited by the locking screw 29, so as to ensure the stability of the movable support leg 22 when fixing the steel cage 300.

[0045] Specifically, four support frames 2 are included, and the four support frames 2 are arranged in an array.

[0046] Example 2

[0047] Reference Figure 3 As shown, this embodiment provides a steel cage hoisting and fixing assembly device, including a steel cage hoist 200 and a steel cage fixing support device 100 as described in Embodiment 1. The steel cage 300 fixing support device 100 is located below the steel cage hoist 200.

[0048] Reference Figure 3 and Figure 4 As shown, the steel cage hanger 200 includes a hanger 3, a lifting lug 4, a hook 8 and a diagonal chain 5. The hanger 3 includes two cross-arranged support rods 31, and the two ends of each support rod 31 form a hanging foot. The two support rods 31 are perpendicular to each other, so that the connection line between the four hanging feet forms a regular quadrilateral. The lifting lug 4 is provided with an upper hanging point 41, a lower hanging point 42 and a hook point 43. The upper hanging point 41 is located above the hanger 3, the lower hanging point 42 is located below the hanger 3, and the hook point 43 is located below the hanger 3; the lifting lug 4 is rotatably connected to the hanging foot. The upper hanging point 41 is connected to the crane through a first steel wire rope 6, and the first steel wire rope 6 is inclined; the lower hanging point 42 is connected to the stirrups on the steel cage 300 through a second steel wire rope 7, and the second steel wire rope 7 is vertical. Since the connection line of the four hanging feet forms a regular quadrilateral, the inclination angles of the four hanging ears 4 are changed at the same time to make the inclination angles of the four hanging ears 4 the same, so that the connection line between the four lower hanging points 42 forms a regular quadrilateral, which is suitable for the corresponding diameter of the steel cage 300. The hook 8 is installed at the intersection of the two support rods 31, and the inclined chain 5 includes a plurality of interlocking buckles, so that one buckle is buckled with the hook point 43, and one buckle is buckled with the hook 8. During the lifting process, the rotation angle of the hanging ear 4 is limited by the inclined chain 5.

[0049] When hoisting the steel cage 300, the first steel wire rope 6 applies an oblique pulling force to the lifting ear 4, so that the lifting ear 4 has a tendency to rotate to be parallel to the first steel wire rope 6, and the oblique chain 5 applies a pulling force to the other end of the lifting ear 4. Since the length of the oblique chain 5 is fixed, the rotation of the lifting ear 4 is restricted. By changing the engagement of different buckles with the hooks 8, the length of the oblique chain 5 can be changed, thereby changing the angle of the lifting ear 4, so that the positional relationship between the lower hanging points 42 corresponds to the diameter of the steel cage 300, so that the second steel wire rope 7 applies a vertical pulling force to the steel cage 300 to lift the steel cage 300.

[0050] The present embodiment provides a combined device for lifting and fixing a steel cage 300, which connects a lifting ear 4 and a hook 8 through an oblique chain 5, so that the lifting ear 4 remains in an inclined state, and different buckles on the oblique chain 5 are connected to the hook 8, thereby changing the inclination angle of the lifting ear 4, thereby changing the position of the lower lifting point 42 to adapt to steel cages 300 of different diameters, ensuring that when lifting steel cages 300 of different diameters, the steel cage 300 is not affected by horizontal forces, thereby avoiding deformation of the steel cage 300.

[0051] Specifically, the support rod 31 includes a first rod body and a second rod body that are arranged at intervals; the ear piece 4 is disposed between the first rod body and the second rod body, and is rotatably connected to the support rod 31 via a hinge shaft 32 .

[0052] Specifically, the distance L1 from the upper hanging point 41 to the hinge shaft 32 can be made smaller than the distance L2 from the lower hanging point 42 to the hinge shaft 32, so that the adjustment range of the lower hanging point 42 is increased when the lifting ear 4 is rotated, thereby increasing the diameter variation range of the steel cage 300.

[0053] Specifically, it also includes a suspension rod 81; one end of the suspension rod 81 is threaded with a second nut 82, and the other end passes through the hanger 3 and is connected to the hook 8. Since the distance of the inclined chain 5 adjusted each time is a unit length of a buckle, the adjustment accuracy of the position of the lower suspension point 42 is limited, and the position of the hook 8 is adjusted by the second nut 82, which can improve the adjustment accuracy.

[0054] Construction process:

[0055] To hoist the steel cage 300, connect the first steel wire rope 6 to the hook of the crane, initially hoist the sling, adjust the buckle of the inclined chain 5 to connect it with the hook 8, and then adjust the second nut 82 to change the height of the hook 8, thereby adjusting the angle of the lifting ear 4 so that the position of the lower hanging point 42 adapts to the diameter of the steel cage 300. Finally, connect the second steel wire rope 7 to the steel cage 300 and hoist the steel cage 300, and lower the steel cage 300 into the pile hole until the stirrups at the top of the steel cage 300 are slightly higher than the movable support legs 22.

[0056] To extend the steel cage 300, move the movable support leg 22 to below the stirrup and move the limiter 23 upward so that the connecting plate 25 abuts against the inner wall of the stirrup; remove the segment steel cage 300 from the hoist and temporarily support and fix the segment steel cage 300 with the fixed support device 100, and hoist and move the segment steel cage 300 downward to align the two and perform the steel bar extension operation.

[0057] The steel cage 300 is lowered, the limiting member 23 is moved down to below the stirrup, and then the movable support leg 22 is moved horizontally to separate the movable support leg 22 from the stirrup, and then the extended steel cage 300 is connected below.

[0058] The above operation process is repeated until the installation of all the steel cages 300 is completed.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
