[0034] Please also read Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 , a recyclable steel cage triangular support device provided by the present invention is now described. The recyclable steel cage triangular support device comprises a connecting pipe 1 and a triangular support unit 2. The connecting pipe 1 is used to pass through the stirrups 1601 of the steel cage 160, the two ends of the connecting pipe 1 are closed, and the side wall of the connecting pipe 1 is provided with air holes 11. The triangular support unit 2 is located between the connecting pipe 1 and the stirrups 1601, and the triangular support unit 2 comprises three support components 21, and the three support components 21 are evenly distributed around the circumference of the connecting pipe 1, and the support component 21 comprises a fixed pipe 211, a sliding shaft 212, a sealing plug 213 and a support member 214, the fixed pipe 211 is arranged along the radial direction of the connecting pipe 1, and one end of the fixed pipe 211 is fixedly connected to the connecting pipe 1 and communicated with the inside of the connecting pipe 1; the sliding shaft 2 12 is slidably provided in the fixed tube 211; the sealing plug 213 is slidably provided in the fixed tube 211, the sealing plug 213 is located on the side of the sliding shaft 212 facing the connecting tube 1, and the sealing plug 213 is fixedly connected to the sliding shaft 212; the support member 214 is fixedly connected to one end of the sliding shaft 212 located outside the fixed tube 211, and the sliding of the sliding shaft 212 can enable the support member 214 to tighten or loosen the stirrup 1601.

[0035] Compared with the prior art, the recyclable steel cage triangular support device provided by the present invention injects high-pressure gas into the connecting pipe 1 through the air vent 11. After the high-pressure gas in the connecting pipe 1 enters the fixed pipe 211, the sliding shaft 212 is driven to slide in the direction of the stirrup 1601, so that the support member 214 presses the stirrup 1601, and the three support members 214 form three angles of support for the stirrup 1601. The sealing plug 213 can prevent the high-pressure gas in the fixed pipe 211 from flowing out. When the stirrups 1601 are no longer needed to be supported, the high-pressure gas in the fixed tube 211 and the connecting tube 1 flows out from the air vent 11. At this time, the sliding shaft 212 can be driven to slide in the direction of the connecting tube 1, so that the support member 214 loosens the stirrups 1601, and then drives the connecting tube 1, the triangular support unit 2, etc. to withdraw from the steel cage 160, so that the device can be recycled, thereby avoiding the method of welding three supporting steel bars on the stirrups 1601 to prevent the steel cage 160 from deforming. Since the supporting steel bars cannot be recycled, the problem of material waste is caused.

[0036] In some embodiments, see Figure 7 The end of the sliding shaft 212 located in the fixed tube 211 has a first sliding portion 2121 protruding outward along the radial direction of the sliding shaft 212, and the first sliding portion 2121 is slidably fitted with the fixed tube 211. The end of the fixed tube 211 away from the connecting tube 1 has a first end wall 2111, and the first end wall 2111 is slidably sleeved outside the sliding shaft 212. The supporting assembly 21 also includes a connecting member 215 and a compression spring 216. The connecting member 215 has a second sliding portion 2151 slidably arranged in the fixed tube 211, and the second sliding portion 2151 is sleeved and fixed on the sliding shaft 212. The compression spring 216 is sleeved on the sliding shaft 212, and the two ends of the compression spring 216 are respectively in contact with the second sliding portion 2151 and the first end wall 2111. The rebound force of the compression spring 216 acts on the second sliding part 2151. When the high-pressure gas in the fixed tube 211 is withdrawn, the rebound force of the compression spring 216 can drive the sliding shaft 212 to slide toward the connecting tube 1 through the connecting member 215, thereby allowing the support member 214 to loosen the stirrup 1601.

[0037] In some embodiments, see Figure 3 and Fig.11 The support member 214 has an arc groove 2141. When the support member 214 squeezes the stirrup 1601, the support member 214 can fit with the stirrup 1601 through the arc groove 2141, thereby avoiding relative displacement between the support member 214 and the stirrup 1601 along the length direction of the connecting pipe 1.

[0038] In some embodiments, see Figure 3and Figure 7 The side wall of the fixed tube 211 is provided with a sliding hole 2112, and the sliding hole 2112 extends along the length direction of the fixed tube 211. The connecting member 215 has a third sliding portion 2152 that slides through the sliding hole 2112. When the support member 214 does not press the stirrup 1601, the sliding cooperation between the sliding hole 2112 and the third sliding portion 2152 can limit the support member 214 from rotating with the sliding shaft 212.

[0039] In some embodiments, see Figure 4 and Fig. 9 , the reusable steel cage triangular support device also includes a fixing seat 3. The fixing seat 3 is fixedly connected to the end face of the first end of the connecting pipe 1 and closes the first end of the connecting pipe 1. The fixing seat 3 is provided with a hoisting hole 31, and the axis of the hoisting hole 31 is perpendicular to the connecting pipe 1. Among them, the second end of the connecting pipe 1 has a second end wall 12 that closes the second end of the connecting pipe 1. The fixing seat 3 and the second end wall 12 respectively close the two ends of the connecting pipe 1. Since the support member 214 is fitted with the stirrup 1601 through the arc groove 2141, the relative displacement of the support member 214 and the stirrup 1601 along the length direction of the connecting pipe 1 is avoided. Therefore, in this embodiment, the steel cage 160 can be hoisted into the hole through the hoisting hole 31.

[0040] Furthermore, a triangular bracing unit 2 is provided at each stirrup 1601 of the steel cage 160 .

[0041] In some embodiments, see Figure 1 The triangular support unit 2 further includes a fixing ring 22. The fixing ring 22 is coaxially sleeved outside the connecting pipe 1, and the fixing ring 22 is sleeved and fixed outside the three fixing pipes 211. The fixing ring 22 can limit the deformation of the fixing pipe 211.

[0042] In some embodiments, see Fig.12 , the reusable steel cage triangular support device also includes a mobile frame 4 and a support shaft 5. The mobile frame 4 has a plurality of rolling wheels 41 for rolling along the ground. The support shaft 5 is horizontally arranged and connected to the mobile frame 4, and the support shaft 5 is used to pass through the fixed ring 22 and support the fixed ring 22. The mobile frame 4 can be moved by the rolling wheels 41. After the steel cage 160 is processed, it will be placed horizontally. At this time, the support shaft 5 supports the connecting pipe 1, the triangular support unit 2, etc. by supporting the fixed ring 22, and the connecting pipe 1, the triangular support unit 2, etc. are inserted into the steel cage 160 by the movement of the mobile frame 4. In this embodiment, the connecting pipe 1 is also in a horizontal state.

[0043] In some embodiments, see Figure 2 and Figure 5The recyclable steel cage triangular support device also includes a rubber sleeve 6, a rotating ring 7, an air inlet pipe 8, a one-way valve 9 and a limit ring 10. The rubber sleeve 6 is sleeved and fixed on the outside of the connecting pipe 1, and the rubber sleeve 6 is provided with a first docking hole 61 connected to the air vent 11. The rotating ring 7 is rotatably sleeved on the outside of the rubber sleeve 6, and the rotating ring 7 is provided with a second docking hole 71 and an air outlet 72, and the air outlet 72 and the second docking hole 71 are respectively located on both sides of the rubber sleeve 6. One end of the air inlet pipe 8 is fixedly connected to the rotating ring 7 and is connected to the second docking hole 71. The one-way valve 9 is arranged on the air inlet pipe 8. There are two limit rings 10, and the limit rings 10 are sleeved and fixed on the outside of the connecting pipe 1, and the two limit rings 10 are respectively fitted with the two end faces of the rotating ring 7. Among them, the rotation of the rotating ring 7 can make the second docking hole 71 and the air outlet 72 communicate with the first docking hole 61 successively. The two limit rings 10 can limit the axial movement of the rotating ring 7 along the connecting pipe 1. When the rotating ring 7 rotates to connect the second docking hole 71 with the first docking hole 61, the air inlet pipe 8 is connected to the connecting pipe 1 through the air vent 11, and the air inlet pipe 8 is connected to the high-pressure gas source, so that the high-pressure gas provided by the high-pressure gas source enters the connecting pipe 1. When the support 214 squeezes the stirrup 1601, the connection between the air inlet pipe 8 and the high-pressure gas source is disconnected. At this time, the one-way valve 9 can prevent the high-pressure gas in the connecting pipe 1 from flowing out, and the rubber sleeve 6 can prevent the high-pressure gas in the connecting pipe 1 from flowing out from between the rubber sleeve 6 and the rotating ring 7. When the high-pressure gas in the connecting pipe 1 needs to flow out, the operator holds the air inlet pipe 8, and then drives the rotating ring 7 to rotate until the air outlet 72 is connected to the first docking hole 61, so that the high-pressure gas in the connecting pipe 1 flows out from the air vent 11, and then flows to the outside through the first docking hole 61 and the air outlet 72. At this time, the operator is on the side of the connecting pipe 1 away from the air outlet 72, so as to prevent the high-pressure gas flowing out of the air outlet 72 from spraying onto the operator.

[0044] In some embodiments, see Figure 2 and Figure 6The reusable steel cage triangular support device also includes a fixed shaft 110, a screw rod 120, a limiting shaft 130 and a butt joint tube 140. The fixed shaft 110 is located on one side of the air intake pipe 8 along the axial direction of the connecting tube 1, and one end of the fixed shaft 110 is fixedly connected to the connecting tube 1. The screw rod 120 is located on the side of the fixed shaft 110 facing the air intake pipe 8, the screw rod 120 is parallel to the connecting tube 1 and one end is fixedly connected to the air intake pipe 8. The limiting shaft 130 is located on the side of the screw rod 120 facing the fixed shaft 110, the limiting shaft 130 is arranged parallel to the screw rod 120 and one end is fixedly connected to the fixed shaft 110, and the end of the limiting shaft 130 facing the screw rod 120 has an anti-slip portion 1301 protruding radially outward along the limiting shaft 130. One end of the butt joint pipe 140 has a third end wall 1401, the third end wall 1401 is slidably sleeved outside the limit shaft 130 and the anti-slip portion 1301 is located inside the butt joint pipe 140, and the butt joint pipe 140 is provided with an internal thread. When the second butt joint hole 71 is connected to the first butt joint hole 61, the butt joint pipe 140 can be sleeved outside the screw rod 120 and be threadedly connected to the screw rod 120 through the internal thread. The limit shaft 130 is fixedly connected to the connecting pipe 1 through the fixed shaft 110. The rotation of the rotating ring 7 can be limited by the threaded connection between the butt joint pipe 140 and the screw rod 120, so that the second butt joint hole 71 and the first butt joint hole 61 are kept in communication. When the rotating ring 7 needs to rotate, the threaded connection between the butt joint pipe 140 and the screw rod 120 is disconnected. The anti-slip portion 1301 is used to prevent the third end wall 1401 from sliding off the limit shaft 130.

[0045] In some embodiments, see Figure 5 , the reusable steel cage triangular support device also includes an exhaust pipe 150. One end of the exhaust pipe 150 is fixedly connected to the rotating ring 7 and is connected to the air outlet 72. The high-pressure gas flowing out of the air outlet 72 flows into the exhaust pipe 150, and then flows out of the exhaust pipe 150 and then diffuses, which can further prevent the high-pressure gas from spraying onto the operator who drives the rotating ring 7 to rotate. Furthermore, if the rebound force of the compression spring 216 cannot make the arc groove 2141 of the support member 214 break away from the contact with the stirrup 1601, the air in the connecting pipe 1 and the fixed pipe 211 can be extracted through the exhaust pipe 150, and the negative pressure can be used to make the sliding shaft 212 slide in the direction of the connecting pipe 1.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
