[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a rebar cage positioning and hoisting device, comprising:

[0028] Positioning frame 100 is set at the top of the rebar cage hoisting pit;

[0029] The limiting component 200 is used to limit the steel cage when it is hoisted by a crawler crane. The limiting component 200 includes two symmetrical sliding plates 201 that are slidably disposed on the inner wall of the positioning frame 100, and limiting plates 202 that are respectively fixed on the surfaces of the two sliding plates 201. The limiting component 200 also includes a first motor 203 fixed on the outer surface of the positioning frame 100 for driving the two sliding plates 201 to move simultaneously toward the middle.

[0030] See Figure 2 and Figure 3 The inner wall of the positioning frame 100 has two symmetrical rectangular grooves, and the two ends of the two sliding plates 201 are slidably connected to the inner walls of the two rectangular grooves respectively. The inner wall of the positioning frame 100 is fixed with two symmetrical first limiting rods 204, and the surfaces of the two sliding plates 201 are each provided with a first sliding hole that is slidably connected to the outer surface of the first limiting rod 204.

[0031] Specifically, by setting the first limit rod 204, the stability of the sliding plate 201 during movement is effectively guaranteed.

[0032] See Figure 4 The output end of the first motor 203 extends into the interior of a rectangular slot and is fixed with a bidirectional lead screw 205. The surfaces of the two sliding plates 201 are provided with threaded holes that are threaded to the outer surface of the bidirectional lead screw 205.

[0033] Specifically, by setting up a bidirectional lead screw 205, the rotation of the first motor 203 can drive the bidirectional lead screw 205 to rotate, thereby driving the two sliding plates 201 to move simultaneously towards the middle or to both sides.

[0034] See Figure 3 The inner wall of the other rectangular groove is fixed with a second limiting rod 206, and the surfaces of the two sliding plates 201 are each provided with a second sliding hole that is slidably connected to the outer surface of the second limiting rod 206.

[0035] Specifically, by setting a second limiting rod 206, the stability of the sliding plate 201 during sliding can be further ensured under the action of the second limiting rod 206.

[0036] In this embodiment, by setting a limiting component 200, when the device is hoisted by a crawler crane, it can drive the two sliding plates 201 to move towards the center simultaneously, thereby driving the two limiting plates 202 to move towards the center simultaneously, so that the surfaces of the two limiting plates 202 contact the surface of the steel cage, thereby achieving effective limiting of the steel cage during lowering and ensuring the stability of the steel cage during lowering.

[0037] Example 2

[0038] Based on Example 1, and differing from Example 1 in that,

[0039] A rebar cage positioning and hoisting device further includes:

[0040] The auxiliary lowering component 300 is used to assist in lowering the steel cage during hoisting.

[0041] See Figure 3 and Figure 4 The auxiliary lowering component 300 includes a mounting groove on the surface of the limiting plate 202, and two symmetrical rotating shafts 301 rotatably disposed on the inner wall of the mounting groove. The surfaces of the two rotating shafts 301 are fitted with transmission rollers 302, and the surfaces of the two transmission rollers 302 are fitted with rubber conveyor belts 303.

[0042] Specifically, by setting up a rubber conveyor belt 303, the rotation of the rubber conveyor belt 303 can assist in the lowering of the steel cage.

[0043] See Figure 3 and Figure 4 The outer surface of the limiting plate 202 is fixed with a second motor 304, and the output end of the second motor 304 extends into the interior of the mounting groove and is fixedly connected to the end of a rotating shaft 301.

[0044] Specifically, by setting a second motor 304, the rotation of the second motor 304 can smoothly drive the rubber conveyor belt 303 to rotate.

[0045] See Figure 4 A support plate 305 is fixedly provided on the inner wall of the mounting groove, and the outer surface of the support plate 305 is slidably connected to the inner ring surface of the rubber conveyor belt 303.

[0046] Specifically, by setting up the support plate 305, the steel cage can be prevented from deforming the rubber conveyor belt 303, thus ensuring the smooth transport of the steel cage.

[0047] In this embodiment, by setting up an auxiliary lowering component 300, when the two limiting plates 202 limit the steel cage, they can drive the rubber conveyor belt 303 to rotate, thereby achieving the purpose of assisting in the lowering of the steel cage and ensuring that the steel cage can be lowered smoothly.

[0048] Working principle: When hoisting the reinforcing cage using a crawler crane, the positioning frame 100 can be placed at the top of the reinforcing cage foundation pit. After the reinforcing cage enters the positioning frame 100, the first motor 203 is started. The rotation of the first motor 203 drives the double-acting screw 205 to rotate. The rotation of the double-acting screw 205 drives the two sliding plates 201 to move towards the center simultaneously, thereby driving the two limiting plates 202 to move towards the center simultaneously, so that the surfaces of the two limiting plates 202 contact the surface of the reinforcing cage. At this time, the outer surface of the reinforcing cage can contact the two limiting plates. The surface of plate 202 slides without clamping the rebar cage, effectively limiting its movement during lowering and ensuring stability. When the two limiting plates 202 limit the rebar cage, the second motor 304 is activated. The rotation of the second motor 304 drives a rotating shaft 301 to rotate, which in turn drives a transmission roller 302 to rotate, thereby driving the rubber conveyor belt 303 to rotate. This achieves the purpose of assisting in the lowering of the rebar cage, ensuring its smooth lowering.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
