One end of the locking cylinder 3 is rotatably connected to the first crossbar 1, and the other end is detachably connected to the second crossbar 2, thereby connecting the corresponding first crossbar 1 and the second crossbar 2. The connecting rod 4 is arranged between the two first crossbars 1 or between the two second crossbars 2, connecting the two first crossbars 1 or the two second crossbars 2, and the connecting rod 4 is located on the inner side of one end of the first crossbar 1 and the second crossbar 2 away from the locking cylinder 3. The suspension rod 5 is arranged at one end of the first crossbar 1 and the second crossbar 2 away from the locking cylinder 3, and one end of the suspension rod 5 away from the first crossbar 1 or the second crossbar 2 is connected to an external suspension device.
[0026] In this embodiment, one end of the locking cylinder 3 close to the first cross bar 1 is sleeved outside the first cross bar 1. Figure 6 , Figure 7 As shown, an outer ring 13 is fixed on the outside of the first crossbar 1, and an annular groove is provided on the inner wall of the locking cylinder 3. The outer ring 13 is inserted into the annular groove, so that the locking cylinder 3 is rotatably connected to the first crossbar 1 without axial displacement. A locking channel 6 is provided on the side of the locking cylinder 3 close to the second crossbar 2, and an inlet that is connected to the outside is provided at one end of the locking channel 6 close to the second crossbar 2. A locking rod 7 is fixed on the end of the second crossbar 2 close to the locking cylinder 3, and the locking rod 7 is perpendicular to the second crossbar 2. The locking rod 7 enters the locking channel 6 from the inlet and passes through the locking channel 6 to move to the end of the locking channel 6 away from the second crossbar 2. A limit assembly is provided at the end of the locking channel 6 away from the second crossbar 2 to prevent the locking rod 7 from falling out.
[0027] Specifically, in this embodiment, if Figure 4 As shown, the locking channel 6 includes a transverse channel close to the second crossbar 2 and a longitudinal channel away from the second crossbar 2. The transverse channel can be directly connected to the longitudinal channel, or the transverse channel and the longitudinal channel can be connected through an L-shaped channel. Figure 5 As shown, an L-shaped channel is provided between the transverse channel and the longitudinal channel in this embodiment, and the limiting assembly includes a limiting column 8 and a limiting stopper rod 9 respectively provided on both sides of the longitudinal channel, the limiting column 8 can be telescopically provided, and the limiting stopper rod 9 is rotatably connected to the locking cylinder 3. Specifically, a mounting groove 14 is provided on the outer side of the locking cylinder 3, and the mounting groove 14 extends into the outer side wall of the locking cylinder 3, the limiting column 8 is inserted into the mounting groove 14, and a spring is provided between the limiting column 8 and the bottom of the mounting groove 14, and the two ends of the spring are respectively fixedly connected to the limiting column 8 and the bottom of the mounting groove 14. A mounting rod 15 is fixed on the outer side of the locking cylinder 3, and the limiting stopper rod 9 is rotatably installed on the mounting rod 15, and the limiting stopper rod 9 can rotate around the mounting rod 15.
[0028] By setting a limit assembly, when the locking rod 7 penetrates into the end of the locking channel 6 away from the second cross bar 2, the limit stop rod 9 is rotated to press the limit column 8 into the installation groove 14, so that the limit stop rod 9 is rotated to above the limit column 8, and the limit column 8 is extended, so that the locking rod 7 can be restricted above the limit stop rod 9, so that no relative movement occurs between the locking rod 7 and the locking cylinder 3.
[0029] Preferably, in this embodiment, the outer end surface of the limit column 8 is inclined so that the limit column 8 is longer at the top and shorter at the bottom, and when the limit column 8 is in an extended state, the bottom of the outer end surface of the limit column 8 is flush with the side of the limit stop rod 9 close to the locking cylinder 3. When the limit stop rod 9 passes through the limit column 8 from bottom to top, the limit column 8 can shrink under the squeezing of the limit stop rod 9, thereby eliminating the need to manually press the limit column 8, and the operation is more convenient.
[0030] In some other embodiments, the locking cylinder 3 may be threadedly connected to the second cross bar 2 .
[0031] In this embodiment, a cylinder handle 10 is fixed to the outside of the locking cylinder 3 , so that during installation, the locking cylinder 3 can be easily rotated through the cylinder handle 10 , and an anti-slip sleeve 17 is arranged on the outside of the cylinder handle 10 .
[0032] In this embodiment, the connecting rod 4 passes through the two first cross bars 1 or the two second cross bars 2, and the connecting rod 4 is threadedly connected to the two first cross bars 1 or the two second cross bars 2, so that the distance between the two first cross bars 1 and the distance between the two second cross bars 2 can be adjusted according to the steel cage 16, and rod handles 11 are provided at both ends of the connecting rod 4 for easy use.
[0033] In this embodiment, the first cross bar 1 and the second cross bar 2 are rotatably provided with a lifting ring 12 at one end away from the locking cylinder 3, the lifting ring 12 rotates around a horizontal axis, and the lifting rod 5 is connected to the lifting ring 12. Specifically, the lifting rod 5 includes a plurality of ribs arranged up and down, and two adjacent ribs are threadedly connected, the bottom of the lowest rib is connected to the lifting ring 12, and the top of the highest rib is connected to an external lifting device.
[0034] The bored pile foundation reinforcement cage in the present embodiment is a recyclable suspension rod device, wherein the suspension rod 5 and the first cross bar 1 as well as the suspension rod 5 and the second cross bar 2 are connected by a suspension ring 12. Since the suspension ring 12 can rotate around the horizontal axis and the end of the first cross bar 1 or the second cross bar 2, when in use, after the suspension rod 5 is connected to the lifting device and before being connected to the reinforcement cage 16, the suspension rod 5 and the first cross bar 1 or the second cross bar 2 are perpendicular to the ground, occupying a small area and not affecting other operations. When in use, the suspension rod 5 passes through the reinforcement cage 16 and is located under at least one circular sleeve, and is locked by the locking tube 3, so that the reinforcement cage 16 can be lifted, and can be disassembled and reused after lifting.
[0035] The suspension rod 5 is configured as a multi-section detachably connected rod body, so that the overall length of the suspension rod 5 can be set according to demand, and the adaptability is stronger.
[0036] The working principle of the recyclable hanging rod device of the bored pile foundation reinforcement cage in this embodiment is:
[0037] During installation, two first cross bars 1 and two second cross bars 2 are inserted from both sides of the steel cage 16, and at least one circular sleeve is located above the first cross bar 1 and the second cross bar 2. The end of the second cross bar 2 close to the first cross bar 1 is inserted into the locking cylinder 3. At the same time, the locking cylinder 3 is rotated to make the locking rod 7 enter the locking channel 6 from the entrance and pass through the locking channel 6 to the end of the locking channel 6 away from the second cross bar 2. The limit stopper 9 is rotated to the limit column 8 above and abuts against the limit column 8, and the locking rod 7 is limited above the limit stopper 9, so that there is no relative movement between the locking rod 7 and the locking cylinder 3. Then the top of the hanging rod 5 is connected to the lifting device, and the steel cage 16 is hoisted. After the hoisting is in place, the recyclable hanging rod device of the bored pile foundation steel cage is disassembled and reused.
