Description

Technical field:

[0001] The utility model relates to the field of pipe pile production equipment, in particular to a pipe pile concrete pouring device. Background technology:

[0002] Prestressed high-strength concrete pipe piles are made using the pre-stressed centrifugal forming process and steam-cured to form a hollow cylindrical concrete prefabricated component. In the construction field, they are driven into the soil by a pile driver as a foundation.

[0003] In the manufacturing process of pipe piles, concrete needs to be poured into a mold, in which a steel bar skeleton is pre-installed. The mold is two semi-cylindrical shapes, divided into an upper mold and a lower mold. The inner cavity of the mold is a cylindrical cavity. The mold is provided with a number of disc-shaped protrusions on the outside, which are used to cooperate with the centrifuge in the centrifugal forming process. During centrifugal forming, the mold rolls along the center of each disc protrusion, and the concrete slurry inside is evenly distributed to the inner wall of the mold through centrifugal force, and finally a hollow cylindrical pipe pile is made;

[0004] The existing casting is generally open-mold casting, that is, casting first and then closing the two semicircular molds. When casting with open molds, the slump of concrete must not be too large, otherwise the concrete will overflow from the mold during casting, resulting in insufficient concrete casting volume and insufficient wall thickness of the final product. If the slump of the concrete is too small, a higher speed and time are required in the subsequent centrifugal molding process to ensure that the bubbles in the concrete are completely discharged, which is not conducive to subsequent centrifugal molding. In addition, due to the open-mold casting, the concrete slurry is usually poured into the lower mold under the action of gravity, and the aggregate may be retained on the steel skeleton. After the upper mold is closed, the aggregate in the concrete is more likely to accumulate in the upper mold, resulting in different densities of the two halves of the concrete of the product, which affects the quality of the final product. Utility model content:

[0005] The utility model aims to provide a pipe pile concrete pouring device to solve the problems of insufficient concrete pouring amount and uneven pouring in the prior art.

[0006] The utility model is implemented by the following technical scheme: a pipe pile concrete pouring device, characterized in that it comprises a track, a pipe pile carrier, a grouting pipe supporting mechanism, a concrete pump and a grouting pipe; a pipe pile carrier is provided on the track for reciprocating movement, a concrete pump is fixedly provided at one end of the track, a grouting pipe supporting mechanism is provided between the pipe pile carrier and the concrete pump and for reciprocating movement along the track, a grouting pipe is placed on the grouting pipe supporting mechanism, and one end of the grouting pipe is connected to the discharge port of the concrete pump; a plurality of mold rolling mechanisms are fixedly installed on the pipe pile carrier, and a weighing sensor is fixedly installed between the pipe pile carrier and the mold rolling mechanism.

[0007] Furthermore, the mold rolling mechanism includes a bracket, a roller and a rolling motor. The bracket is fixedly installed on the top of the pipe pile carrier, and a weighing sensor is fixedly installed between the bracket and the pipe pile carrier. Two rollers are rotatably provided on the bracket, and grooves matching the pipe pile mold are integrally formed on the outer edges of the rollers. The two rollers are connected by a chain transmission, and the rolling motor is connected to one of the rollers by a chain transmission.

[0008] Furthermore, a driving motor is fixedly provided on the pipe pile carrier vehicle, and the driving motor is connected to the wheels of the pipe pile carrier vehicle through a chain transmission.

[0009] Furthermore, the grouting pipe supporting mechanism includes a fixed bracket and several mobile brackets. The fixed bracket is fixedly set on the ground between the track and the concrete pump, and the mobile bracket is reciprocatingly set on the track between the fixed bracket and the pipe pile carrying vehicle. The fixed bracket and its adjacent mobile bracket, each mobile bracket, and the pipe pile carrying vehicle and its adjacent mobile bracket are all connected by a traction chain.

[0010] Furthermore, the grouting pipe supporting mechanism also includes rollers, which are rotatably provided on the fixed bracket and the movable bracket, and the outer edge of the roller is integrally formed with a groove matching the grouting pipe.

[0011] Furthermore, a conical guide sleeve is sleeved on the outer wall of one end of the grouting pipe inserted into the pipe pile mold.

[0012] The advantages of the utility model are as follows: the pipe pile mold is placed on a rolling mechanism for rolling, and the pipe pile carrier drives the pipe pile mold, and the grouting pipe is gradually pulled out of the mold during grouting, so that concrete slurry can be evenly injected into the pipe pile mold, and the pipe pile mold rotates while grouting, so that aggregates in the concrete slurry can be distributed more evenly, and a weighing sensor is provided at the bottom of the rolling mechanism, which can obtain the grouting amount in real time to ensure sufficient grouting; at the same time, grouting can be carried out on the mold after closing, which solves the problem of easy overflow of concrete slurry with a large slump.

[0022] like Figure 2As shown in the figure: a plurality of mold rolling mechanisms 6 are fixedly installed on the pipe pile carrier 2, and the mold rolling mechanism 6 includes a bracket 601, a roller 602 and a rolling motor 603. A bracket 601 is fixedly installed on the top of the pipe pile carrier 2, and a weighing sensor 7 is fixedly installed between the bracket 601 and the pipe pile carrier 2. Two rollers 602 are rotatably arranged on the bracket 601, and the outer edges of the rollers 602 are integrally formed with grooves matching the pipe pile mold 8. When grouting, the pipe pile mold 8 is placed on the two rollers 602 of the rolling mechanism 6, and the disc-shaped protrusions on the outer wall of the pipe pile mold 8 can be aligned with the rollers. The grooves of 602 fit together to play a limiting role. A plurality of rolling mechanisms 6 are arranged side by side on the pipe pile carrier 2. All rollers 602 are located at the same horizontal plane, which can ensure that the pipe pile mold 8 above it is concentric with the grouting pipe 5. The two rollers 602 are connected by a chain transmission, and the rolling motor 603 is connected to one of the rollers 602 by a chain transmission. During the grouting process, the rolling motor 603 drives the two rollers 602 to rotate, which can drive the upper pipe pile mold 8 to roll. The pipe pile mold 8 is grouting while rolling, ensuring that the concrete slurry is evenly distributed in the pipe pile mold 8.

[0023] like Figure 3 As shown: a driving motor 201 is fixedly provided on the pipe pile carrier 2, and the driving motor 201 is connected to the wheel 202 of the pipe pile carrier 2 through a chain drive. The driving motor 201 is used to provide power to the pipe pile carrier 2, and the driving motor 2 is controlled to rotate forward and reverse, so that the pipe pile carrier 2 can move back and forth on the track 1; during grouting, the pipe pile carrier 2 is first controlled to stop at a position away from the grouting pipe 5, so as to facilitate the placement of the pipe pile mold 8 on the pipe pile carrier 2. After the pipe pile mold 8 is placed, the pipe pile carrier 2 is first controlled to move toward the direction of the concrete pump 4 until the grouting pipe 5 is completely inserted into the pipe pile mold 8, and then as the concrete slurry is injected into the pipe pile mold 8, the pipe pile carrier 2 moves in the opposite direction, slowly pulls out the pipe pile mold 8, and fills the pipe pile mold 8 with a sufficient amount of concrete slurry.

[0024] like Figure 4As shown: the grouting pipe supporting mechanism 3 includes a fixed bracket 301 and a plurality of mobile brackets 302, the fixed bracket 301 is fixedly arranged on the ground between the track 1 and the concrete pump 4, the mobile bracket 302 is reciprocatingly arranged on the track 1 between the fixed bracket 301 and the pipe pile bearing vehicle 2, the fixed bracket 301 and its adjacent mobile bracket 302, each mobile bracket 302, and the pipe pile bearing vehicle 2 and its adjacent mobile bracket 302 are all connected by a traction chain 303, when the pipe pile bearing vehicle 2 moves toward the concrete pump 4, the pipe pile bearing vehicle 2 contacts the mobile bracket 302 and pushes the mobile bracket 302 forward until the grouting pipe 5 is inserted into the bottom of the pipe pile mold 8, and ... During the grouting process, the pile carrier 2 moves in the opposite direction, and each traction chain 303 is tightened in turn. The pile carrier 2 pulls each mobile bracket 302 backward through the traction chain 303, and the mobile bracket 302 lifts the grouting pipe 5 pulled out of the pile mold 8 while moving, to prevent the grouting pipe 5 from falling and bending due to gravity; until all sections of the traction chain 303 are tightened, the grouting pipe 5 is also completely pulled out of the pile mold 8, the fixed bracket 301 and the mobile bracket 302 are evenly distributed below the entire length of the grouting pipe 5, supporting the grouting pipe 5, preventing the grouting pipe 5 from sagging and bending due to gravity, and keeping it aligned with the center position of the pile mold 8, so that it can be smoothly inserted into the grouting port of the pile mold 8 during the next grouting;

[0025] like Figure 5 As shown: a roller 304 is rotatably provided on the fixed bracket 301 and the movable bracket 302, and a groove matching the grouting pipe 5 is integrally formed on the outer edge of the roller 304. The roller 304 is used to fix the grouting pipe 5 supported above it to ensure that the grouting pipe 5 is concentric with the pile mold 8; a conical guide sleeve 501 is sleeved on the outer wall of one end of the grouting pipe 5 inserted into the pile mold 8, and the guide sleeve 501 is used to contact the steel skeleton preset in the pile mold 8 after the grouting pipe 5 is inserted into the pile mold 8. The conical guide sleeve 501 is used to guide the insertion direction of the grouting pipe 5, so that the head of the grouting pipe 5 can be smoothly inserted into the steel skeleton without getting stuck.

[0026] Working principle: when grouting is needed, firstly, the pipe pile mold 8 with the pre-set steel skeleton is placed on the rolling mechanism 6 above the pipe pile carrier vehicle 2 through the overhead crane, and the disc-shaped protrusion on the outer ring of the mold is aligned with the groove of the roller 602, and then the drive motor 201 is started to control the pipe pile carrier vehicle 2 to move toward the grouting pipe 5, and the grouting pipe 5 is inserted into the bottom of the pipe pile mold, and the concrete pump 4 is started to start grouting, and the rolling motor 603 of the rolling mechanism 6 is started at the same time, and the drive motor 201 is controlled to reverse, and the pipe pile mold 8 rotates while slowly retreating. The weight of the injected concrete can be obtained in real time through the weighing sensor 7 between the rolling mechanism 6 and the pipe pile carrier vehicle 2, and the overall grouting amount can be controlled by controlling the retreat speed of the pipe pile carrier vehicle 2. Grouting is carried out while the pipe pile mold 8 rotates, which can ensure that the aggregate in the concrete slurry is evenly distributed in the steel skeleton, and there will be no problem of aggregate deposition on one side of the mold, until the grouting pipe 5 is completely pulled out of the pipe pile mold 8 and the designed grouting weight is reached at the same time, and the grouting is completed.
