[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This utility model discloses a rebar cage hoisting device for bored pile construction, comprising: a main support base 1; a lifting ring 2 welded to the top of the main support base 1, which supports other parts of the device structure; in use, the lifting ring 2 on the top of the main support base 1 can be fixed to the cable on the crane; two support plates 3 are slidably installed on the inner side of the bottom of the main support base 1, which supports the hanging plate 6; a lead screw 4 is also rotatably installed on the inner side of the main support base 1, and handwheels 5 are fixed at both ends of the lead screw 4. When the rebar cage needs to be hoisted, the lead screw 4 is first rotated by the handwheels 5. 4. When rotating, the threads on its left and right sides will engage with the threaded holes on the top of the support plate 3, causing it to slide synchronously in the opposite direction in the T-shaped groove inside the main support seat 1, thereby adjusting the two hanging plates 6 to the inside of the rebar cage; the bottom of the support plate 3 is welded with hanging plates 6, and one side of the support plate 3 is also slidably installed with locking rods 7. When in use, the rebars on both sides of the rebar cage can be embedded in the grooves inside the hanging plates 6, and then the locking rods 7 can be pushed down to the bottom again. At this time, the bottom end of the locking rods 7 will be inserted into the circular groove on the hanging plate 6, so the locking rods 7 can cover the rebars and prevent them from falling off.

[0028] In this embodiment, as Figures 1-5 As shown, the hanging plate 6 is an L-shaped plate with an opening on one side. The top of the opening side of the hanging plate 6 is also provided with a circular groove with an inner diameter equal to the outer diameter of the bottom end of the locking rod 7. When in use, the steel bars on both sides of the steel cage can be embedded into the groove on the inner side of the hanging plate 6. Then, the locking rod 7 is pushed down to the bottom again. At this time, the bottom end of the locking rod 7 will be inserted into the circular groove on the hanging plate 6. Therefore, the locking rod 7 can cover the steel bars and prevent them from falling off.

[0029] In this embodiment, as Figures 3-5As shown, the upper part of the support plate 3 is a T-shaped structure. The inner side of the main support base 1 is provided with a corresponding T-shaped groove with a bottom opening. The upper part of the support plate 3 can slide left and right in the T-shaped groove inside the main support base 1. When the lead screw 4 rotates, it will cooperate with the threaded hole on the top of the support plate 3 through the threads on its left and right sides to drive it to slide synchronously in the opposite direction in the T-shaped groove inside the main support base 1, so as to ensure the stability of the support plate 3 when it is displaced.

[0030] In this embodiment, as Figures 1-4 As shown, the locking rod 7 can slide up and down in the round hole inside the support plate 3. When the locking rod 7 slides down to the bottom, its bottom end will be inserted into the round groove on the hanging plate 6. At the same time, the locking rod 7 will close the opening on one side of the hanging plate 6. In use, the steel bars on both sides of the steel cage can be embedded into the groove inside the hanging plate 6. Then, the locking rod 7 is pushed down to the bottom again. At this time, the bottom end of the locking rod 7 will be inserted into the round groove on the hanging plate 6. Therefore, the locking rod 7 can block the steel bars and prevent them from falling off.

[0031] In this embodiment, as Figure 3 As shown, the screw 4 has two threads on its outer side, and the threads on the left and right sides of the screw 4 are symmetrical. When the steel cage needs to be lifted, the screw 4 is rotated by the handwheel 5. When the screw 4 rotates, it will be driven to slide synchronously in the opposite direction in the T-shaped groove inside the main support seat 1 through the threads on its left and right sides cooperating with the threaded holes on the top of the support plate 3, thereby adjusting the two hanging plates 6 to the inside of the steel cage.

[0032] In this embodiment, as Figures 1-5 As shown, the top of each support plate 3 is provided with threaded holes corresponding to the outer threads of the lead screw 4, and the two support plates 3 are symmetrically arranged on the left and right with the center position of the main support seat 1 as the reference. When the steel cage needs to be lifted, the lead screw 4 is rotated by the handwheel 5. When the lead screw 4 rotates, it will be driven to slide synchronously in opposite directions in the T-shaped groove inside the main support seat 1 through the threads on its left and right sides cooperating with the threaded holes on the top of the support plate 3. This allows the two hanging plates 6 to be adjusted to the inside of the steel cage, and steel cages of different specifications can be lifted and placed.

[0033] Example 2, based on Example 1, such as Figures 1-6 As shown, both the bottom of the locking rod 7 and the hanging plate 6 are equipped with magnets. The adjacent magnetic poles of the magnets inside the locking rod 7 and the hanging plate 6 are opposite magnetic poles. When in use, the locking rod 7 can be pushed down to the bottom. At this time, the bottom of the locking rod 7 will be inserted into the circular groove on the hanging plate 6. Therefore, the locking rod 7 can block the steel bar and prevent it from falling off. Moreover, at this time, the magnets inside the locking rod 7 and the hanging plate 6 will be firmly attracted to each other, thus preventing the locking rod 7 from moving during the hoisting process.

[0034] The working principle of this embodiment is as follows: When using this device to hoist the reinforcing cage for bored pile construction, first fix the lifting ring 2 at the top of the main support 1 to the cable on the crane. When the reinforcing cage needs to be hoisted, first drive the screw rod 4 to rotate through the handwheel 5. When the screw rod 4 rotates, it will engage with the threaded holes at the top of the support plate 3 through the threads on its left and right sides, causing it to slide synchronously in opposite directions in the T-groove inside the main support 1. This allows the two hanging plates 6 to be adjusted to the inside of the reinforcing cage. After the two hanging plates 6 are adjusted to the inside of the reinforcing cage, drive the screw rod 4 to rotate in the opposite direction to move the two support plates 3 and the hanging plates 6 away from each other. At the same time, push the locking rod 7 upward to the top. This allows the reinforcing bars on both sides of the cage to be embedded in the grooves inside the hanging plate 6. Finally, push the locking rod 7 down to the bottom again. At this point, the bottom end of the locking rod 7 will insert into the circular groove on the hanging plate 6, thus blocking the reinforcing bars and preventing them from falling off. Moreover, the magnets inside the locking rod 7 and the hanging plate 6 will firmly attract each other, thus preventing the locking rod 7 from moving during the hoisting process. Then, the reinforcing cage can be hoisted using this device. After hoisting, push the locking rod 7 up to the top again and adjust the screw 4 to move the support plate 3 left and right to detach it from the reinforcing cage.

[0035] The following points should be noted in this article:

[0036] 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0037] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
