[0019] A method for using a steel-concrete composite beam sliding construction device comprises the following steps:

[0020] S1: The extrusion shaft will squeeze the annular frame and the first force spring toward the inside of the connection box. When the annular frame is squeezed and moves toward the inside of the connection box, the short shaft rotating on the inner wall of the annular frame will rotate by utilizing the meshing relationship between the first gear and the first tooth plate. It should be understood here that each first tooth plate is fixed to the inner wall of the connection box, and the first gear is meshed with the first tooth plate. Therefore, if the first gear wants to move toward the inside of the connection box with the annular frame, the first gear will rotate. In addition, since the first gear is connected to the input end of the gear transmission, the first gear will transmit the rotating power to the gear transmission, and the gear speed change structure inside the gear transmission will transfer the slower rotation The power is converted into faster rotational power and transmitted to the second gear to drive the second gear to rotate, so the first gear and the second gear will both present a state of motion in which they move laterally while rotating, but the rotation speed of the second gear is faster than that of the first gear. When the second gear moves to the position of the second toothed plate, the teeth on the surface of the second gear will mesh with the teeth on the surface of the second toothed plate, and the rotation speed of the second gear is greater than that of the first gear, so the second gear will push the second toothed plate and the moving frame to move, and the movement of the moving frame will drive the circular column to pass through the hole opened on the surface of the protective pad and enter into the two connecting holes opened on the surface of the combined beam, so that the circular column is clamped in the connecting holes opened on the surface of the combined beam;

[0021] S2: When the circular column, the moving frame and the rotating block are moving, the first circular ring arranged inside the rotating block will not move with the movement of the rotating block under the limitation of the transmission shaft, the baffle plate and the fixed frame. After the circular column, the rotating block and the moving frame move a certain distance, the entrance of the first spiral groove opened on the inner wall of the rotating block will move to the back of the first circular ring, and as the circular column continues to move, the three groups of first spiral strips fixed on the outer surface of the first circular ring will enter the interior of the first spiral groove, and the first circular ring and the transmission shaft cannot rotate under the limitation of the baffle plate. Therefore, if the circular column and the rotating block want to continue to move, the rotating block rotatably connected to the inner wall of the circular column will rotate along the first spiral strip under the action of the first spiral groove, thereby driving the rotating shaft rotatably connected to the inner wall of the rotating block and the third gear to rotate, thereby pushing the two limiting plates to extend to both sides, thereby limiting the combined beam from the other end of the combined beam. It should be understood here that at this time, the second spiral strip fixed on the outer surface of the second circular ring is just at the entrance of the second spiral groove, and the first spiral strip also just comes out from the outlet of the first spiral groove;

[0022] S3: When the device needs to be disassembled, the rotating plate can be rotated. When the rotating plate rotates, the threaded shaft threadedly connected to its outer surface will also rotate. The lifting cylinder is threadedly connected to the threaded shaft, so the rotation of the threaded shaft will eventually drive the lifting cylinder to move upward, and the lifting cylinder will move upward along the two limit shafts during the upward movement to prevent the lifting cylinder from rotating. When the lifting cylinder moves to the top of the transmission shaft, the circular block is pulled out from the inside of the moving plate and the connecting box, and the transmission shaft will move to the bottom of the lifting cylinder under the joint action of the baffle and the second force spring. During the movement of the transmission shaft, it will drive the second The spiral strip enters the interior of the second spiral groove, and the rotation trajectory of the second spiral groove is opposite to that of the first spiral groove. Therefore, when the first circular ring and the second circular ring are subjected to forces in the same direction and pass through the first spiral groove and the second spiral groove, the rotation forces generated are opposite. Therefore, when the second spiral strip passes through the second spiral groove, it will drive the rotating block and the third gear to rotate in the opposite direction, thereby driving the two limit plates back to their original positions. At this time, the circular column that has lost the snap-fitting relationship can be forcefully pulled out, and then the moving plate can be pulled to reset, and the rotating plate can be flipped and rotated to return the lifting cylinder to its original position. After the device is reset, you only need to repeat the above operation when using it next time.

[0023] The beneficial effects of the present invention are:

[0024] The steel-concrete composite beam sliding construction device and method provided by the present invention, by setting a trigger unit, can convert the thrust received by the connecting box when squeezing the composite beam into power for driving the circular column to extend into the interior of the composite beam, thereby achieving the purpose of automatically clamping the circular column into the interior of the composite beam.

[0025] By setting up a locking unit, the internal circular column limiting locking structure can be extended by the locking unit. The locking unit and the trigger unit cooperate with each other to limit the combined beam from both sides of the combined beam respectively, so that the connection relationship between the circular column and the combined beam is tightened.

[0026] By providing a disassembly mechanism, the disassembly mechanism can be used to contact the limit of the combination beam by the locking unit. By providing a trigger unit, a locking unit and a disassembly mechanism, it can be effectively avoided that during the use of the device, the connection box can be installed on the combination beam with the help of tools and bolts, which will prolong the time that workers work in a small space and increase the risk of workers falling.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] Embodiment 1

[0049] As a further limitation of the mounting mechanism 2 of the present invention, the trigger unit 21 includes an annular frame 2107, the annular frame 2107 is arranged inside the connection box 1, the front of the annular frame 2107 is fixedly connected with an extrusion shaft 2101, the extrusion shaft 2101 penetrates the connection box 1 and extends to the front of the connection box 1, the outer surface of the extrusion shaft 2101 is slidably connected to the inside of the connection box 1, the inner bottom wall of the connection box 1 is fixedly connected with a rectangular block 2113, the upper surface of the rectangular block 2113 is provided with a first T-shaped slide groove 2114, and the first T-shaped slide groove 2114 is slidably connected to the inside of the first T-shaped slide block 2112 The upper surface of the first T-shaped slider 2112 is fixedly connected to the bottom surface of the annular frame 2107, the back surface of the annular frame 2107 is fixedly connected to the first force spring 2110, one end of the first force spring 2110 away from the annular frame 2107 is fixedly connected to the inner wall of the connection box 1, the inner wall of the annular frame 2107 is rotatably connected to two short shafts 2103, the outer surface of each short shaft 2103 is fixedly connected to a first gear 2111, the inner wall of the annular frame 2107 is fixedly connected to two gearboxes 2117, and the input end of each gearbox 2117 is fixedly connected to the first gear 21 11 is close to one end of the gearbox 2117, and the output end of each gearbox 2117 is fixedly connected to the second gear 2118. The inner wall of the connection box 1 is fixedly connected to two first tooth plates 2109, and the teeth of each first tooth plate 2109 are meshed with the teeth of the first gear 2111. The inside of the annular frame 2107 is slidably connected to two moving frames 2105. The side of the two moving frames 2105 close to each other is fixedly connected to the second tooth plate 2106, and the side of the two moving frames 2105 away from each other is provided with a second T-shaped slide groove 2104. Each moving frame 2105 is provided with a second tooth plate 2106. 5 are fixedly connected to the front of the connecting box 1 with a circular column 2102, the outer surface of each circular column 2102 is slidably connected to the inside of the connecting box 1, the inner wall of the connecting box 1 is fixedly connected to two second T-shaped sliders 2108, the outer surface of each second T-shaped slider 2108 is slidably connected to the inside of the second T-shaped slide groove 2104, and by setting a trigger unit 21, the trigger unit 21 can convert the thrust received by the connecting box 1 when squeezing the combined beam into the power to drive the circular column 2102 to extend into the inside of the combined beam, thereby achieving the purpose of automatically clamping the circular column 2102 into the inside of the combined beam;

[0050] See also Fig. 9 The bottom surface of each moving frame 2105 is fixedly connected to two rectangular plates 2116, and the inner wall of each group of rectangular plates 2116 is rotatably connected to two rotating rollers 2115. The outer surface of each rotating roller 2115 is in contact with the inner bottom wall of the connection box 1. By providing the rectangular plates 2116 and the rotating rollers 2115, the rotating rollers 2115 rotate on the inner walls of the rectangular plates 2116, which can reduce the resistance encountered by the moving frame 2105 when moving.

[0051] The specific implementation of this embodiment is as follows: when the device is needed, the device can be lifted, and the two circular columns 2102 are aligned with the two connection holes on the surface of the composite beam, and then the device is pushed as a whole to move toward the composite beam. When the extrusion shaft 2101 contacts the composite beam, the protective pad 322 can be removed, and then the protective pad 322 can be placed on the surface of the extrusion shaft 2101 from above the extrusion shaft 2101. As the device continues to move, the extrusion shaft 2101 will squeeze the annular frame 2107 and the first force spring 2110 toward the inside of the connection box 1. When the annular frame 2107 and the first force spring 2110 are pressed against the surface of the extrusion shaft 2101, the annular frame 2107 and the first force spring 2110 will be pressed against the surface of the extrusion shaft 2101. When the annular frame 2107 is squeezed and moves toward the inside of the connection box 1, the short shaft 2103 rotating on the inner wall of the annular frame 2107 will rotate by utilizing the meshing relationship between the first gear 2111 and the first tooth plate 2109. It should be understood here that each first tooth plate 2109 is fixed to the inner wall of the connection box 1, and the first gear 2111 is meshed with the first tooth plate 2109. Therefore, if the first gear 2111 wants to move toward the inside of the connection box 1 with the annular frame 2107, the first gear 2111 will rotate. In addition, since the first gear 2111 and the gear variable The first gear 2111 is connected to the input end of the gear box 2117, so the first gear 2111 will transmit the rotational power to the gear box 2117, and the gear speed change structure inside the gear box 2117 will convert the slower rotational power into faster rotational power and transmit it to the second gear 2118 to drive the second gear 2118 to rotate. Therefore, the first gear 2111 and the second gear 2118 will show a motion state of moving horizontally while rotating at the same time, but the rotation speed of the second gear 2118 is faster than that of the first gear 2111. When the second gear 2118 moves to the first gear 2118, the second gear 2118 will rotate at the same time. When the second tooth plate 2106 is in the position, the teeth on the surface of the second gear 2118 will mesh with the teeth on the surface of the second tooth plate 2106, and the rotation speed of the second gear 2118 is greater than that of the first gear 2111, so the second gear 2118 will push the second tooth plate 2106 and the moving frame 2105 to move, and the movement of the moving frame 2105 will drive the circular column 2102 to pass through the hole opened on the surface of the protective pad 322 and enter into the two connecting holes opened on the surface of the combined beam, so that the circular column 2102 is clamped in the connecting holes opened on the surface of the combined beam, thereby achieving the purpose of connection.

The locking unit 22 cooperates with the trigger unit 21, and the locking unit 22 can lock the device and the composite beam to limit the position.

[0054] As a further limitation of the mounting mechanism 2 of the present invention, the locking unit 22 includes two fixed frames 2211, the back of each fixed frame 2211 is fixedly connected to the inner wall of the connection box 1, a transmission shaft 2203 is arranged inside each fixed frame 2211, and the end of each transmission shaft 2203 close to the circular column 2102 passes through the fixed frame 2211 and the circular column 2102 in sequence and extends to the interior of the circular column 2102, the outer surface of each transmission shaft 2203 is fixedly connected to a baffle 2212, the front side of each baffle 2212 contacts the inner wall of the fixed frame 2211, a square card groove 2204 is provided on the outer surface of each transmission shaft 2203, the outer surface of each transmission shaft 2203 is fixedly connected to a first circular ring 2209 and a second circular ring 2213, the outer surface of each first circular ring 2209 is fixedly connected to three groups of first spiral strips 2208, and the outer surface of each second circular ring 2213 is fixedly connected to three groups of second spiral strips 2215, the inner wall of each circular column 2102 is fixedly connected to a bearing 2205, the inner ring of each bearing 2205 is fixedly connected to a rotating block 2206, the inner wall of each rotating block 2206 is provided with three groups of first spiral grooves 2207 and three groups of second spiral grooves 2214, the inner wall of each rotating block 2206 and the inner wall of the circular column 2102 are rotatably connected to a rotating shaft 2202, and the outer surface of each rotating shaft 2202 is fixedly connected to a third gear 221 0, the outer surface of each third gear 2210 is meshed with two limit plates 2201, and the outer surface of each limit plate 2201 is slidably connected to the inside of the circular column 2102. By setting a locking unit 22, the locking unit 22 can be used to extend the internal circular column 2102 limit locking structure, and the locking unit 22 cooperates with the trigger unit 21 to limit the combined beam from both sides of the combined beam, so that the connection relationship between the circular column 2102 and the combined beam is tighter.

[0055] The specific implementation of this embodiment is as follows: when the circular column 2102, the moving frame 2105 and the rotating block 2206 are in the process of moving, the first circular ring 2209 provided inside the rotating block 2206 will not move along with the movement of the rotating block 2206 under the limitation of the transmission shaft 2203, the baffle 2212 and the fixed frame 2211; when the circular column 2102, the rotating block 2206 and the moving frame 2105 move a certain distance, the entrance of the first spiral groove 2207 provided on the inner wall of the rotating block 2206 will move to the back side of the first circular ring 2209; and as the circular column 2102 continues to move, the three groups of first spiral strips 2208 fixed on the outer surface of the first circular ring 2209 will enter into the first spiral groove 2207, and the first circular ring 2209 and the transmission shaft 220 Under the limitation of the baffle 2212, the circular column 2102 and the rotating block 2206 cannot rotate. Therefore, if the circular column 2102 and the rotating block 2206 want to continue to move, the rotating block 2206 rotatably connected to the inner wall of the circular column 2102 will rotate along the first spiral strip 2208 under the action of the first spiral groove 2207, thereby driving the rotating shaft 2202 rotatably connected to the inner wall of the rotating block 2206 and the third gear 2210 to rotate, thereby pushing the two limiting plates 2201 to extend to both sides, thereby limiting the combined beam from the other end of the combined beam.

By setting a trigger unit 21, a locking unit 22 and a disassembly mechanism 3, it can be effectively avoided that the connection box 1 needs to be installed on the combination beam with the help of tools and bolts during the use of the device, which will prolong the working time of workers in a small space and increase the risk of workers falling.

By providing the connecting rope 314, the square plate 319 and the circular block 320, the square plate 319 can be fixed by the connecting rope 314, so that the connection position of the circular block 320 can be limited, and the circular block 320 can only move within the diameter range of the connecting rope 314 to prevent the circular block 320 from being lost;

[0060] See also Figure 1A slide rail 305 is provided below the connection box 1, and a self-locking device 309 is slidably connected to the outer surface of the slide rail 305. A protective pad 322 is magnetically attracted to the upper surface of the self-locking device 309. By providing the slide rail 305 and the self-locking device 309, the slide rail 305 can provide a suitable sliding track for the movement of the composite beam. The self-locking device 309 includes a side block, a self-locking rack, a rack rod, a rod rack and a rack rod driving mechanism, and has a rod rack meshed with the self-locking rack, thereby temporarily locking on the slide rail 305, so that the movement of the self-locking rack and the hydraulic cylinder 303 connected to the self-locking rack is restricted, ensuring that when the hydraulic cylinder 303 is working, the self-locking device 309 and the slide rail 305 have sufficient friction to push the steel-concrete composite beam to move;

[0061] See also Figure 1 , the inner wall of the self-locking device 309 is rotatably connected to two first rotating shafts 308, the outer surface of each first rotating shaft 308 is fixedly connected to a transmission plate 307, the inner walls of the two transmission plates 307 are jointly rotatably connected to a second rotating shaft 306, and the outer surface of the second rotating shaft 306 is fixedly connected to a force block 304. By providing the first rotating shaft 308, the transmission plate 307, the second rotating shaft 306 and the force block 304, the self-locking device 309 and the connection box 1 that are not in the same horizontal plane can be connected together;

[0062] See also Figure 2 Two fixed blocks 313 are fixedly connected to the back of the connecting box 1, and the inner walls of the two fixed blocks 313 are rotatably connected to the third rotating shaft 310. The outer surface of the third rotating shaft 310 is fixedly connected to the connecting plate 302, and the back of the connecting plate 302 is fixedly connected to the hydraulic cylinder 303. The telescopic end of the hydraulic cylinder 303 is fixedly connected to the front of the force-bearing block 304. By setting the fixed blocks 313, the third rotating shaft 310 and the hydraulic cylinder 303, the operation of the hydraulic cylinder 303 can apply thrust to the force-bearing block 304, and the force-bearing block 304 will transfer the thrust to the self-locking device 309, and the self-locking device 309 is locked on the slide rail 305. Therefore, the reaction force can be used to push the combined beam to move on the surface of the slide rail 305.

[0063] The specific implementation of this embodiment is as follows: when the device needs to be disassembled, the rotating plate 301 can be rotated. When the rotating plate 301 rotates, the threaded shaft 316 threadedly connected to its outer surface will also rotate, and the lifting cylinder 312 is threadedly connected to the threaded shaft 316, so the rotation of the threaded shaft 316 will eventually drive the lifting cylinder 312 to move upward, and the lifting cylinder 312 will move upward along the two limit shafts 321 during the upward movement to prevent the lifting cylinder 312 from rotating. When the lifting cylinder 312 moves to the top of the transmission shaft 2203, the circular block 320 is pulled out from the inside of the moving plate 318 and the connecting box 1, and the transmission shaft 2203 will move downward to the bottom of the lifting cylinder 312 under the joint action of the baffle 2212 and the second force spring 311. During the movement of the transmission shaft 2203, it will drive the outer surface of the second circular ring 2213 to be fixed The second spiral strip 2215 enters the interior of the second spiral groove 2214. It should be understood here that the rotation trajectory of the second spiral groove 2214 is opposite to the rotation trajectory of the first spiral groove 2207. Therefore, when the first circular ring 2209 and the second circular ring 2213 are subjected to forces in the same direction and pass through the first spiral groove 2207 and the second spiral groove 2214, the rotational forces generated are opposite. Therefore, when the second spiral strip 2215 passes through the second spiral groove 2214, it will drive the rotating block 2206 and the third gear 2210 to rotate in the opposite direction, thereby driving the two limit plates 2201 back to their original positions. At this time, the circular column 2102 that has lost its engagement can be forcefully pulled out, and then the moving plate 318 is pulled to reset, and the rotating plate 301 is flipped and rotated to make the lifting cylinder 312 return to its original position. After the device is reset, it only needs to repeat the above operation when it is used next time.

[0064] A method for using a steel-concrete composite beam sliding construction device comprises the following steps:

[0065] S1: The extrusion shaft 2101 will squeeze the annular frame 2107 and the first force spring 2110 toward the inside of the connection box 1. When the annular frame 2107 is squeezed and moves toward the inside of the connection box 1, the short shaft 2103 rotating on the inner wall of the annular frame 2107 will rotate by utilizing the meshing relationship between the first gear 2111 and the first tooth plate 2109. It should be understood here that each first tooth plate 2109 is fixed to the inner wall of the connection box 1, and the first gear 2111 is meshed with the first tooth plate 2109. Therefore, if the first gear 2111 wants to move toward the inside of the connection box 1 with the annular frame 2107, the first gear 2111 will rotate. In addition, since the first gear 2111 is connected to the input end of the gear transmission 2117, the first gear 2111 will transmit the rotating power to the gear transmission 2117, and the gear speed change structure inside the gear transmission 2117 will transmit the slower The rotational power is converted into a faster rotational power and transmitted to the second gear 2118, driving the second gear 2118 to rotate, so the first gear 2111 and the second gear 2118 will both present a motion state of moving laterally while rotating, but the rotation speed of the second gear 2118 is faster than that of the first gear 2111. When the second gear 2118 moves to the position of the second toothed plate 2106, the teeth on the surface of the second gear 2118 will mesh with the teeth on the surface of the second toothed plate 2106, and the rotation speed of the second gear 2118 is greater than that of the first gear 2111, so the second gear 2118 will push the second toothed plate 2106 and the moving frame 2105 to move, and the movement of the moving frame 2105 will drive the circular column 2102 to pass through the hole opened on the surface of the protective pad 322 and enter the two connecting holes opened on the surface of the combined beam, so that the circular column 2102 is clamped in the connecting holes opened on the surface of the combined beam;

[0066] S2: When the circular column 2102, the moving frame 2105 and the rotating block 2206 are moving, the first circular ring 2209 provided inside the rotating block 2206 will not move along with the movement of the rotating block 2206 under the limitation of the transmission shaft 2203, the baffle plate 2212 and the fixed frame 2211. When the circular column 2102, the rotating block 2206 and the moving frame 2105 move a certain distance, the entrance of the first spiral groove 2207 provided on the inner wall of the rotating block 2206 will move to the back side of the first circular ring 2209. With the continuous movement of the circular column 2102, the three groups of first spiral strips 2208 fixed on the outer surface of the first circular ring 2209 will enter into the first spiral groove 2207. The first circular ring 2209 and the transmission shaft 2203 are in the baffle plate 2212. 212 is limited and cannot rotate, so if the circular column 2102 and the rotating block 2206 want to continue to move, the rotating block 2206 rotatably connected to the inner wall of the circular column 2102 will rotate along the first spiral strip 2208 under the action of the first spiral groove 2207, thereby driving the rotating shaft 2202 rotatably connected to the inner wall of the rotating block 2206 and the third gear 2210 to rotate, thereby pushing the two limiting plates 2201 to extend to both sides, thereby limiting the combined beam from the other end of the combined beam. It should be understood here that at this time, the second spiral strip 2215 fixed on the outer surface of the second circular ring 2213 is just at the entrance of the second spiral groove 2214, and the first spiral strip 2208 also just comes out of the exit of the first spiral groove 2207;

[0067] S3: When the device needs to be disassembled, the rotating plate 301 can be rotated. When the rotating plate 301 rotates, the threaded shaft 316 threadedly connected to its outer surface will also rotate, and the lifting cylinder 312 is threadedly connected to the threaded shaft 316, so the rotation of the threaded shaft 316 will eventually drive the lifting cylinder 312 to move upward, and the lifting cylinder 312 will move upward along the two limit shafts 321 during the upward movement to prevent the lifting cylinder 312 from rotating. When the lifting cylinder 312 moves to the top of the transmission shaft 2203, the circular block 320 is pulled out from the inside of the moving plate 318 and the connecting box 1, and the transmission shaft 2203 will move to the bottom of the lifting cylinder 312 under the joint action of the baffle 2212 and the second force spring 311. During the movement of the transmission shaft 2203, it will drive the second spiral strip fixed on the outer surface of the second circular ring 2213 2215 enters the interior of the second spiral groove 2214. It should be understood here that the rotation trajectory of the second spiral groove 2214 is opposite to the rotation trajectory of the first spiral groove 2207. Therefore, when the first circular ring 2209 and the second circular ring 2213 are subjected to forces in the same direction and pass through the first spiral groove 2207 and the second spiral groove 2214, the rotational forces generated are opposite. Therefore, when the second spiral strip 2215 passes through the second spiral groove 2214, it will drive the rotating block 2206 and the third gear 2210 to rotate in the opposite direction, thereby driving the two limit plates 2201 back to their original positions. At this time, the circular column 2102 that has lost the snap-fitting relationship can be forcefully pulled out, and then the moving plate 318 is pulled to reset, and the rotating plate 301 is flipped and rotated to make the lifting cylinder 312 return to its original position. After the device is reset, it only needs to repeat the above operation when it is used next time.

6. A method for using a steel-concrete composite beam sliding construction device, using the steel-concrete composite beam sliding construction device according to any one of claims 1 to 5, characterized in that: The specific steps include: S1: The extrusion shaft (2101) will press the annular frame (2107) and the first force spring (2110) toward the inside of the connection box (1). When the annular frame (2107) is pressed and moves toward the inside of the connection box (1), the short shaft (2103) rotating on the inner wall of the annular frame (2107) will rotate by utilizing the meshing relationship between the first gear (2111) and the first tooth plate (2109). Each first tooth plate (2109) is fixed to the inner wall of the connection box (1), and the first gear ( The first gear (2111) is meshed with the first tooth plate (2109), so if the first gear (2111) wants to move toward the inside of the connection box (1) along with the annular frame (2107), the first gear (2111) will rotate. In addition, the first gear (2111) is connected to the input end of the gear transmission box (2117), so the first gear (2111) will transmit the rotational power to the gear transmission box (2117), and the gear speed change structure inside the gear transmission box (2117) will transfer the slower The rotational power is converted into a faster rotational power and transmitted to the second gear (2118), driving the second gear (2118) to rotate, so that the first gear (2111) and the second gear (2118) will both move laterally while rotating, but the rotation speed of the second gear (2118) is faster than that of the first gear (2111). When the second gear (2118) moves to the position of the second tooth plate (2106), the teeth on the surface of the second gear (2118) will contact with the teeth on the second tooth plate (2106). The teeth on the surface of the plate (2106) are meshed, and the rotation speed of the second gear (2118) is greater than that of the first gear (2111), so the second gear (2118) will push the second tooth plate (2106) and the moving frame (2105) to move, and the movement of the moving frame (2105) will drive the circular column (2102) to pass through the hole opened on the surface of the protective pad (322) and enter the two connecting holes opened on the surface of the combined beam, so that the circular column (2102) is clamped in the connecting holes opened on the surface of the combined beam; S2: When the circular column (2102), the moving frame (2105) and the rotating block (2206) are moving, the first circular ring (2209) provided inside the rotating block (2206) will not move along with the movement of the rotating block (2206) under the limitation of the transmission shaft (2203), the baffle (2212) and the fixed frame (2211). When the circular column (2102), the rotating block (2206) and the moving frame (2105) move a certain distance, the entrance of the first spiral groove (2207) provided on the inner wall of the rotating block (2206) will move to the back of the first circular ring (2209). As the circular column (2102) continues to move, the three groups of first spiral strips (2208) fixed on the outer surface of the first circular ring (2209) will enter the first spiral groove (2207), and the first circular ring (2209) and the transmission shaft (2203) will move to the inside of the first spiral groove (2207). 2203) cannot rotate under the limitation of the baffle plate (2212), so if the circular column (2102) and the rotating block (2206) want to continue to move, the rotating block (2206) rotatably connected to the inner wall of the circular column (2102) will rotate along the first spiral strip (2208) under the action of the first spiral groove (2207), thereby driving the rotating shaft (2202) rotatably connected to the inner wall of the rotating block (2206) and the third gear (2210) to rotate, thereby pushing the two limiting plates (2201) to extend to both sides, thereby limiting the combined beam from the other end of the combined beam, at this time, the second spiral strip (2215) fixed on the outer surface of the second circular ring (2213) is just at the entrance of the second spiral groove (2214), and the first spiral strip (2208) also just comes out of the exit of the first spiral groove (2207); S3: When the device needs to be disassembled, the rotating plate (301) can be rotated. When the rotating plate (301) rotates, the threaded shaft (316) threadedly connected to the outer surface of the rotating plate (301) will also rotate. Since the lifting cylinder (312) and the threaded shaft (316) are in a threaded connection relationship, the rotation of the threaded shaft (316) will eventually drive the lifting cylinder (312) to move upward. In the process of moving upward, the lifting cylinder (312) will move upward along the two limit shafts (321) to prevent The lifting cylinder (312) is prevented from rotating. When the lifting cylinder (312) moves to the top of the transmission shaft (2203), the circular block (320) is pulled out from the inside of the moving plate (318) and the connecting box (1). The transmission shaft (2203) moves to the bottom of the lifting cylinder (312) under the joint action of the baffle plate (2212) and the second force spring (311). During the movement of the transmission shaft (2203), the outer surface of the second circular ring (2213) is driven to rotate. The second spiral strip (2215) is fixed to enter the interior of the second spiral groove (2214), and the rotation trajectory of the second spiral groove (2214) is opposite to the rotation trajectory of the first spiral groove (2207). Therefore, when the first circular ring (2209) and the second circular ring (2213) are subjected to forces in the same direction and pass through the first spiral groove (2207) and the second spiral groove (2214), the rotation forces generated are opposite. Therefore, when the second spiral strip (2215) passes through the second spiral groove (2214), it will drive the rotating block (2206) and the third gear (2210) to rotate in the opposite direction, thereby driving the two limit plates (2201) back to their original positions. At this time, the circular column (2102) that has lost the clamping relationship can be pulled out with force, and then the moving plate (318) is pulled to reset, and the rotating plate (301) is flipped and rotated to make the lifting cylinder (312) return to its original position. At this time, after the device is reset, it only needs to repeat the above operation when it is used next time.
