Description

Technical Field

They are mainly composed of cylindrical pile bodies, end plates and steel sleeves. During manufacturing, the pipe piles are centrifuged by centrifugal force to centrifuge the mold. The centrifugal forming device of concrete pipe piles includes two parallel main shafts, on which support wheels are set to support the pipe pile mold. One of the main shafts rotates actively, thereby driving the pipe pile model to rotate at high speed. Through centrifugal forming, the pipe pile is finally formed.

[0043] When the transmission sleeves 53 on both sides are pulled, the two transmission sleeves 53 will pull the two installation sleeves, and the two installation sleeves will pull the two fixing rings 56 through the third bolts 58. The two fixing rings 56 will pull the steel bars 10 installed therebetween, so that the steel bars 10 generate prestress.

[0044] The transmission sleeve 53 and the mounting sleeve 37 can be tightened and fixed by tightening the threaded sleeve 36 , thereby ensuring the stability of the transmission sleeve 53 after being pulled.

[0047] The limiting block 55 designed in the present invention can limit the intermediate rotating rod 9, ensuring that the installation sleeve can drive the intermediate rotating rod 9 to rotate together during the rotation process, so that the concrete adhering to the outer wall of the intermediate rotating rod 9 can be subjected to the centrifugal force released when the intermediate rotating rod 9 rotates, thereby accelerating the separation of the concrete and the intermediate rotating rod 9, rather than simply relying on the forming mold 5 to drive the concrete to rotate centrifugally to cause the concrete to separate from the intermediate rotating rod 9.

[0048] The sliding of the intermediate rotating rod 9 can be controlled by the telescopic rod 2; the conveying support 8 supports the sliding of the telescopic rod 2 and the intermediate rotating rod 9, and the function of the first transmission wheel 11 is to reduce the friction resistance of the telescopic rod 2 and the intermediate rotating rod 9 during sliding.

After the forming mold 5 is closed, the upper and lower first connecting plates 40 are fixedly connected by a plurality of evenly distributed first bolts 39; the top of the upper forming mold 5 is detachably mounted with an opening and closing plate 38 by bolts; the upper forming mold 5 and the lower forming mold 5 form a plurality of evenly distributed rotating convex rings after closing; before pouring, the lower forming mold is firstly placed on the bottom support Then, the tied steel bar 10 is placed between the two fixing rings 56 on both sides, and the end of the steel bar 10 is fixed to the fixing ring 56 on the corresponding side; then the upper forming mold 5 is placed on the upper side of the lower forming mold 5, and the upper forming mold 5 and the lower forming mold 5 are connected; the two ends of the forming mold 5 are connected to the two mounting sleeves 37 by bolts; after the upper forming mold 5 and the lower forming mold 5 are closed, a plurality of evenly distributed rotating convex rings are formed, which correspond to the bottom supporting mechanism 7 one by one and rotate with each other. The bottom supporting mechanism 7 supports and guides the forming mold 5.

[0053] like Figure 1 , 5 As shown, a plurality of top support mechanisms 6 are evenly installed on the upper side of the base, such as Figure 5 , 6As shown, the top support mechanism 6 includes a fixing sleeve 44, a clamping wheel 43, a mounting lug 47, a mounting swing arm 48, a first spring 50, a mounting rod 49, a second bolt 51, and a second connecting plate 52, wherein two mounting lugs 47 are symmetrically fixedly mounted on the upper side of the base 1, the lower ends of the two mounting swing arms 48 are swingably mounted on the two mounting lugs 47, and the upper ends of the two mounting swing arms 48 are respectively provided with a second connecting plate 52; after the two mounting swing arms 48 are closed, the two second connecting plates 52 are tightly fitted and connected by a second bolt 51; a fixing sleeve 44 is fixedly mounted on each mounting swing arm 48, a mounting rod 49 is slidably mounted in the fixing sleeve 44, and a first spring 50 is mounted between the mounting rod 49 and the fixing sleeve 44; the first spring 50 is a compression spring; a clamping wheel 43 is rotatably mounted on the mounting rod 49, and the clamping wheel 43 cooperates with the upper part forming mold 5.

Compared with the traditional method of driving the concrete to rotate only by the friction between the forming mold 5 and the concrete, the insertion rod 63 added in the present invention can further reduce the jumping phenomenon during the centrifugal process.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0057] Implementation method: When using the equipment designed by the present invention, before use, first place the lower half of the forming mold 5 on the bottom support mechanism 7, then place the tied steel bars 10 between the two fixing rings 56 on both sides, and fix the ends of the steel bars 10 to the fixing rings 56 on the corresponding side; then control the telescopic pull rod 2 so that the middle rotating rod 9 is inserted into the inner side of the steel bars 10.

[0058] The third motor 23 is controlled to work, and the third motor 23 drives the second gear 28 to rotate. The rotation of the second gear 28 drives the third gear 30 to rotate. The rotation of the third gear 30 drives the threaded sleeve 34 to rotate. Since the threaded sleeve 34 is rotatably installed on the rotating ring 22, the rotation of the threaded sleeve 34 will drive the installation slide rod 32 to slide. The sliding of the installation slide rod 32 drives the clamping piece 27 to slide, so that the clamping piece 27 cooperates with the installation sleeve 37, and the guide block 42 cooperates with the guide groove 31.

[0059] Afterwards, place the upper molding die 5 on the upper side of the lower molding die 5, and connect the upper molding die 5 and the lower molding die 5; the two ends of the molding die 5 are connected to the two mounting sleeves 37 by bolts; the upper molding die 5 and the lower molding die 5 form a plurality of evenly distributed rotating convex rings which correspond to the bottom supporting mechanism 7 one by one and rotate with each other after closing; then open the opening and closing plate 38 for pouring, and close the opening and closing plate 38 after the pouring is completed.

[0060] Then the second motor 19 is controlled to work, the second motor 19 will drive the second screw 20 to rotate, the second screw 20 drives the support slip ring 21 to slide on the base 1 under the action of the thread, the support slip ring 21 drives the pull ring 35 to slide through the rotating ring 22, the installation slide rod 32 and the clamping part 27, the pull ring 35 drives the fixed slide sleeve 54 to slide through the transmission sleeve 53, the fixed slide sleeve 54 drives the fixed ring 56 to slide through the third bolt 58, the two fixed slip rings pull the steel bar 10 installed therebetween, so that the steel bar 10 generates prestress.

[0061] Afterwards, the fourth motor 26 is controlled to work. The fourth motor 26 can drive the first gear 25 to rotate. The rotation of the first gear 25 drives the gear ring 24 to rotate. The rotation of the gear ring 24 drives the rotating ring 22 to rotate relative to the supporting slip ring 21. The rotation of the rotating ring 22 drives the mounting slide rod 32 installed thereon to rotate around the axis of the rotating ring 22. The mounting slide rod 32 drives the clamping part 27 to rotate. The rotation of the clamping part 27 can drive the mounting sleeve 37 to rotate through the cooperation of the guide block 42 and the guide groove 31. The mounting sleeve 37 rotates through the guide block 64 and the guide groove 59 to drive the fixed sleeve 54 to rotate. The fixed sleeve 54 rotates through the limit block 55 to drive the intermediate rotating rod 9 to rotate. At the same time, the fixed sleeve 54 rotates through the third bolt 58 to drive the fixed ring 56 to rotate. During the rotating centrifuge, the concrete in the forming mold 5 is gradually formed.

[0062] When the intermediate rotating rod 9 is driven to rotate by the limit block 55, when the centrifugal force received by the limit block 55 becomes larger, the limit block 55 will be disengaged from the intermediate rotating rod 9 and lose the driving effect on the intermediate rotating rod 9. At this time, the rotation of the intermediate rotating rod 9 will be relatively slow. In this state, the concrete in the forming mold 5 has been basically formed. At this time, if it is observed that the rotation speed of the intermediate rotating rod 9 slows down, the shell controls the friction block 15 to contact with the intermediate rotating rod 9, and the friction block 15 brakes the rotation of the intermediate rotating rod 9, so that the intermediate rotating rod 9 can stop quickly and can be pulled out by the telescopic pull rod 2.

[0063] Open the connection between the forming mold 5 and the two installation sleeves on both sides, open the third bolts 58 between the fixed installation sleeve and the fixing ring 56, cut off the redundant third bolts 58, and then drive the forming mold 5 to perform the next demoulding process.
