Description

Technical Field

[0001] The invention belongs to the field of pipe pile maintenance, and in particular relates to intelligent maintenance equipment for PHC pipe piles. Background Art

[0002] Based on the prior art, it is found that in the prior art, when curing pipe piles, batches of pipe piles are usually stacked in a curing tank in sequence, which causes adjacent pipe piles to contact each other, and the contact surfaces between the pipe piles are difficult to contact with steam, resulting in uneven steam curing of the pipe piles, affecting the quality of the pipe piles. When the pipe piles are clamped and limited by a clamp for curing, the part where the clamp contacts the pipe piles is also difficult to contact with steam, resulting in uneven steam curing. Also, after the pipe piles are cured and taken out of the curing pool, the steam inside the pipe piles is difficult to be discharged quickly in a short period of time, which can easily threaten the on-site workers. After the curing, the pipe piles should be properly ventilated and discharged to remove the residual steam inside the pipe piles to prevent the subsequent use of the pipe piles from being affected by excessive internal humidity.

[0022] When the electric clamp 211 is closed, its inner diameter is equal to the outer diameter of the pipe pile 3 , and the inner diameter of the limiting ring 212 is larger than the outer diameter of the pipe pile 3 .

[0023] The limiting ring 212 is made of high temperature resistant rubber. A ball bearing is arranged on the inner clamping part of the electric clamp 211 to reduce the friction between the electric clamp 211 and the pipe pile 3.

[0024] Each driving mechanism includes a motor II 301, a spline shaft 302, a spline sleeve 303, an electric actuator I 304 and a connecting rod 305; the motor II 301 is fixedly connected to the lower part of the partition 2; the output shaft of the motor II 301 is fixedly connected to the spline shaft 302; the spline shaft 302 is rotatably connected to the partition 2; the spline sleeve 303 is slidably connected to the spline shaft 302; two electric actuators I 304 are fixedly connected to the bottom of the inner side of the curing tank 1, the electric actuator I 304 is an electric push rod, and the telescopic part of the electric actuator I 304 passes through the partition 2 and is fixedly connected to the connecting rod 305; the connecting rod 305 is rotatably connected to the spline sleeve 303.

[0025] When the pipe pile 3 is steam cured: the external steam generator is connected to the right end of the jet pipe 202 in advance, and the initial state of the electric clamp 211 is the open state, and the initial state of the elastic member III 2091 is the compressed state, and then the pipe pile 3 after being formed and removed from the mold is transferred to the curing tank 1 by the external hoisting equipment. Due to the prior art, when curing the pipe pile 3, batches of pipe piles 3 are usually stacked in the curing tank 1 in sequence, which causes the adjacent pipe piles 3 to be mutually connected. The contact surface between the pipe piles 3 is difficult to contact with the steam, which leads to uneven steam curing of the pipe piles 3 and affects the quality of the pipe piles 3. To solve the above problem, the pipe piles 3 are transferred to the top of the curing pool 1 by external lifting equipment, and the pipe piles 3 are placed on a support plate 206 located above. The two electric clamps 211 are respectively located on the left and right parts of the pipe piles 3. At this time, the middle part of the pipe pile 3 is limited by the support plate 206, and when the pipe pile 3 is separated from the external lifting equipment, the electric clamps 211 are used to fix the pipe pile 3. The weight of the pile 3 itself squeezes the support plate 206 and causes the support plate 206 to move downward. The movement of the support plate 206 drives the sliding block 205 to move. The movement of the sliding block 205 drives the corresponding sliding rod 207 to move downward, thereby compressing the corresponding elastic member II 2071. At the same time, due to the downward movement of the support plate 206, displacement occurs between the support plate 206 and the two sliding plates 208, and then the elastic force of the corresponding elastic member III 2091 causes the two sliding plates 208 to move toward each other. The movement of 208 drives a support plate 210 respectively, and the movement of the support plate 210 drives the corresponding electric clamp 211 to move. At the same time, the movement of the support plate 210 drives the corresponding limit ring 212 to move, so that the two limit rings 212 are both sleeved on the outside of the pipe pile 3, and are respectively located on the left part and the right part of the pipe pile 3, and control the corresponding electric clamp 211 to operate to clamp the left part and the right part of the pipe pile 3, so that the pipe pile 3 is further limited by the two electric clamps 211.

[0026] After one pipe pile 3 is clamped and limited, in order to perform steam curing on multiple pipe piles 3 at the same time, the motor I 201 is controlled to start, and the output shaft of the motor I 201 rotates to drive the jet pipe 202 to rotate, and the rotation of the jet pipe 202 drives the two support frames 203 to rotate, and the rotation of the two support frames 203 drives the multiple fixing frames 204 to rotate, and then drives all the connected parts to rotate, so that the support plate 206 on which the pipe pile 3 is placed rotates, and the other support plate 206 rotates to the upper position, and then the same method as above is used to rotate. The next pipe pile 3 is clamped and limited in position by the method until all the support plates 206 are placed with pipe piles 3, and the corresponding electric clamps 211 are used to clamp and limit the pipe piles 3, so that multiple pipe piles 3 can be clamped and limited in position at the same time, and then the upper cover of the curing pool 1 is transferred to the top of the curing pool 1 by the external lifting equipment, and covered on the top of the curing pool 1, so as to close the curing pool 1, and then the external steam generator is controlled to operate to transmit steam to the jet pipe 202, and the steam is evenly transported to the curing pool 1 through the jet pipe 202. In the curing pool 1, steam curing of multiple pipe piles 3 is achieved, and it is possible to avoid contact between adjacent pipe piles 3, which makes it difficult for the contact surface between the pipe piles 3 to contact with steam, and finally leads to the problem of uneven steam curing of the pipe piles 3. In the process of steam curing, in the same way as above, the motor I 201 is controlled to start, the output shaft of the motor I 201 rotates to drive the jet pipe 202 to rotate, the jet pipe 202 rotates to drive the two support frames 203 to rotate, and then drives all the connected parts to rotate, and then drives all the pipe piles 3 to rotate in the curing pool 1, so that each pipe pile 3 can be in contact with steam. Compared with the prior art, the way in which the pipe piles 3 remain stationary during the steam curing process can further improve the steam curing effect on the pipe piles 3. In addition, by setting two partitions 2, the interior of the curing pool 1 is divided into three spaces, which can prevent steam from entering the space between the curing pool 1 and the partition 2, thereby preventing steam from damaging the mechanical parts in the space between the curing pool 1 and the partition 2.

[0027] And because each pipe pile 3 is clamped and limited by the corresponding support plate 206 and the corresponding electric clamp 211, the part of the pipe pile 3 in contact with the support plate 206 and the part of the pipe pile 3 in contact with the electric clamp 211 are difficult to contact with the steam, resulting in uneven steam curing. During the curing process, the pipe pile 3 is operated by the motor I 201, and finally the pipe pile 3 is rotated in the curing tank 1. When the pipe pile 3 rotates to the lower part of the inner wall of the curing tank 1 and is vertically aligned with the two discs 306, the motor I 201 is controlled to stop operating. At this time, the center of the pipe pile 3 is located above the center of the disc 306, and then the corresponding two electric clamps 211 are controlled to open. The degree of opening causes the electric clamp 211 to no longer clamp and limit the pipe pile 3. At this time, the electric The inner diameter of the clamp 211 is larger than the outer diameter of the pipe pile 3. The pipe pile 3 will move downward under the action of gravity and separate from the support plate 206. The opening spacing of the electric clamp 211 is smaller than the outer diameter of the pipe pile 3, so that the pipe pile 3 will not separate from the electric clamp 211 when moving downward until the lower side of the pipe pile 3 contacts the electric clamp 211 and the limit ring 212 respectively. At this time, the pipe pile 3 is supported by the electric clamp 211 and the limit ring 212, and the center of the pipe pile 3 is aligned with the center of the disc 306. Since the pressure caused by the pipe pile 3 on the support plate 206 disappears, the support plate 206 is reset by the elastic force of the corresponding elastic member II 2071. It is explained here that the elastic force of the elastic member II 2071 is much greater than the elastic force of the elastic member III 2091, thereby causing the support plate 206 to move and squeeze the two The sliding plate 208 causes the two sliding plates 208 to move in opposite directions, and drives all the connected parts to move, thereby causing the two electric clamps 211 to move in opposite directions, and compressing the elastic member III 2091 again. Since a ball bearing is provided on the inner clamping portion of the electric clamp 211, the resistance of the electric clamp 211 during movement is reduced, and the pipe pile 3 will not be scratched, until the two limit rings 212 move in opposite directions to contact the disc 306. At this time, the corresponding electric actuator I 304 is controlled to start and drive the connecting rod 305 to move. The movement of the connecting rod 305 drives the spline sleeve 303 to slide on the spline shaft 302. The sliding of the spline sleeve 303 drives the disc 306 to move. The movement of the disc 306 drives the top block 307 to move, thereby causing the top block 307 to move to the pipe pile. 3, and contacts the inner side of the pipe pile 3, and the limiting block 3061 contacts the outer surface of the pipe pile 3, and at the same time, the top block 307 is continuously moved, so that the tapered portion 3071 of the top block 307 contacts the inner side of the pipe pile 3 and is squeezed and deformed by the inner side of the pipe pile 3, and the movement of the top block 307 drives the corresponding paddle 308 to move, and the movement of the paddle 308 is squeezed and rotated by the inner side of the pipe pile 3, so that the other end of the paddle 308 abuts against the inner side of the pipe pile 3 and is deformed, and at the same time, the corresponding elastic member I 3081 is twisted, so that the pipe pile 3 is limited by the cooperation of the disk 306, the limiting block 3061, the top block 307 and the paddle 308, at this time, the electric clamp 211 is controlled to be fully opened and no longer in contact with the pipe pile 3,Then, the two motors II 301 are controlled to start, and the output shafts of the two motors II 301 rotate to drive a spline shaft 302 to rotate, and the spline shaft 302 rotates to drive the spline sleeve 303 to rotate, and the spline sleeve 303 rotates to drive the corresponding disc 306 to rotate, thereby driving the pipe pile 3 to rotate, so that the part of the pipe pile 3 that contacts the support plate 206 and the part of the pipe pile 3 that contacts the electric clamp 211 can contact with steam through the rotation of the pipe pile 3, thereby reducing the uneven steam curing and further improving the steam curing effect on the pipe pile 3.

[0028] Embodiment 2 Based on the first embodiment, Figure 8 As shown, it also includes a ventilation system; the right part of the curing pool 1 is connected to the ventilation system; the ventilation system includes an outlet pipe 401, a conduit I 402, a three-way pipe 403, a conduit II 404, a telescopic pipe 405, an electric actuator II 406 and a fixing plate 407; the right part of the curing pool 1 is fixedly connected with the outlet pipe 401; the outlet pipe 401 is rotatably connected and communicated with the right end of the jet pipe 202; the upper part of the outlet pipe 401 is fixedly connected and communicated with the conduit I 402, and the conduit I 402 is provided with an electromagnetic valve I; the conduit I 40 2 is fixedly connected to and communicated with a tee pipe 403 at one end away from the air outlet pipe 401; the upper end of the tee pipe 403 is fixedly connected to and communicated with a guide tube II 404, and a solenoid valve II is provided on the guide tube II 404; the left end of the tee pipe 403 is fixedly connected to and communicated with a telescopic pipe 405; two electric actuators II 406 are fixedly connected to the right partition plate 2, and the electric actuators II 406 are electric push rods; the telescopic parts of all the electric actuators II 406 are fixedly connected to a fixed plate 407; the fixed plate 407 is fixedly connected to the telescopic part of the telescopic pipe 405.

[0029] The outer surface of the curing tank 1 is coated with an anti-corrosion coating.

[0030] Connect the external air pump to conduit II 404. When the pipe pile 3 is taken out of the curing pool 1 by external lifting equipment after the curing is completed, the steam in the curing pool 1 will immediately float out after the upper cover of the curing pool 1 is opened, and the steam inside the pipe pile 3 is difficult to be quickly discharged in a short time. If the pipe pile 3 is directly taken out, the high-temperature steam in the pipe pile 3 is very likely to threaten the on-site staff, thereby endangering personal safety. After the curing is completed, the pipe pile 3 should be properly ventilated and discharged to remove the residual steam inside the pipe pile 3 to prevent the subsequent use of the pipe pile 3 from being affected by excessive internal humidity. When the pipe pile 3 needs to be taken out, the top pipe pile 3 is aligned with the telescopic tube 405, and the solenoid valve I on the conduit I 402 is closed, and the conduit II 404 is connected to the curing pool 1. The solenoid valve II on the pipe II 404 is in the open state, and then the two electric actuators II 406 are controlled to start and drive the fixed plate 407 to move. The movement of the fixed plate 407 drives the telescopic tube 405 to move, and then the telescopic tube 405 moves into the pipe pile 3, and then the external air pump is controlled to start to supply gas to the conduit II 404. The gas flows along the conduit II 404, the three-way pipe 403 and the telescopic tube 405, and finally blows into the pipe pile 3, so as to quickly discharge the steam in the pipe pile 3, thereby avoiding the problem that the steam stays in the pipe pile 3 for a long time, which is easy to threaten the on-site staff and endanger the personal safety, and can timely discharge the residual steam inside the pipe pile 3, thereby preventing the pipe pile 3 from being affected by the subsequent use due to the internal humidity being too high.

[0031] In the process of curing the pipe pile 3, in order to allow the steam to quickly enter the inner side of the pipe pile 3 and improve the curing effect of the pipe pile 3, one of the pipe piles 3 is rotated to the lower part of the inner wall of the curing tank 1 and vertically aligned with the two discs 306, and the motor I 201 stops working, at this time, the solenoid valve I on the conduit I 402 is in an open state, the solenoid valve II on the conduit II 404 is in a closed state, and the telescopic pipe 405 is controlled to move into the pipe pile 3 in the same way as above, by adding an outlet pipe 401 and connecting the external steam generator to the outlet pipe 404. 01, thereby allowing part of the steam to flow along the conduit Ⅰ 402, the three-way pipe 403 and the telescopic pipe 405, and then allowing the steam to flow to the jet pipe 202 and the telescopic pipe 405 at the same time, and finally allowing the steam to quickly flow to the inside of the pipe pile 3, thereby quickly making the temperature of the outside of the pipe pile 3 close to the temperature of the outside of the pipe pile 3, and allowing the inside of the pipe pile 3 to be quickly steam-cured, thereby improving the curing effect of the pipe pile 3, and before starting the motor Ⅰ 201 again, control the telescopic pipe 405 to move and reset to avoid interfering with the rotation of the pipe pile 3.
