Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing equipment, and in particular to energy-saving pipe pile concrete admixture proportioning equipment and a method thereof. Background Art

[0002] Pipe piles are mainly used in construction projects to bear the vertical load of buildings and avoid settlement of foundation land. Therefore, pipe piles need to have high tensile strength. In the production process of pipe pile concrete, other materials need to be added to conventional concrete. The admixtures include water reducers, ground slag, etc. These admixtures also need to be added to cement mortar after proportioning, and the admixtures and cement mortar are fully mixed by stirring.

[0003] The amount of cement mortar required for a pipe column is large, so during the mixing process of the cement mortar, the mixing device is subjected to a large load. Conventional mixing devices use a driving motor to drive the mixing shaft to stir the cement mortar. During the stirring process, the friction force when it contacts the cement mortar will be directly transmitted to the motor, which will cause a higher load on the motor. The high load will reduce the speed of the motor. For the mixing device that needs to maintain a certain mixing speed, the reduction in speed will affect the mixing quality of the cement mortar, thereby causing uneven mixing of the cement mortar.

[0016] A method for mixing admixtures for energy-saving pipe pile concrete comprises the following steps:

[0017] Step 1: Put cement, sand and water into the mixing drum in a ratio of 1:3.8:0.9, the motor drives the second gear to rotate through the first gear, and the second gear drives the mixing shaft to mix the mixed cement mortar;

[0018] Step 2: The first gear drives the outer ring to rotate through the inner ring so that the second connecting rod drives the outer ring to rotate, and the outer ring drives the power-assisting plate to assist the cement mortar in the mixing drum to flow and mix;

[0019] Step 3: Add the admixture water reducer, ground slag and silica fume of the pipe pile into the rotating box according to the proportion;

[0020] Step 4: When the rotating box rotates, the admixture put into it will be discharged downward onto the cement mortar through the feeding pipe, and the cement mortar will be stirred by the stirring shaft and the power plate, so that the admixture is mixed with the cement mortar;

[0021] Step 5: During the rotation of the rotating box, the resistance rod is caused to shake continuously under the effect of the resistance ring, and the shaking of the rotating box causes the feeding pipe to shake, thereby preventing the residual admixture in the feeding pipe.

[0022] As described above, the beneficial effects of the energy-saving pipe pile concrete admixture proportioning device and method thereof in the present invention are as follows:

[0023] The transmission can be shared to the four second gears through the first gear, thereby achieving the balance and sharing of the transmission, thereby achieving the effect of labor saving and achieving the purpose of energy saving of the motor. Through different rotation ratios, the speed of the second gear can be faster than that of the first gear, which can effectively convert the rotation of the motor, allowing the stirring shaft to fully stir and mix the cement mortar in a short time, and the spiral stirring effect of the stirring shaft can make the cement mortar form an up and down reflux in the mixing drum, effectively improving the mixing efficiency of the cement mortar;

[0024] The outer ring drives the power plate to rotate inside the mixing drum, thereby realizing horizontal stirring of the cement mortar inside the mixing drum, thereby assisting the flow of the cement mortar, thereby avoiding the inability of the cement mortar to flow and mix effectively when too much cement mortar is stirred, thereby improving the effectiveness of cement mortar mixing. In addition, by stirring the flowing cement mortar, the resistance of the cement mortar to the stirring shaft can be further reduced, thereby reducing the load of the motor and achieving an efficient stirring effect;

[0025] The admixture is dropped downward from the connection point between the feeding pipe and the rotating box, so that the admixture can drop downward from the gap of the connecting rod 1 to the cement mortar in the mixing drum through the feeding pipe in a rotating state. The rotating feeding method can avoid the problem that the admixture cannot be evenly mixed with the cement mortar when the existing admixture is added at a single position. The rotating feeding can make the admixture evenly added to the cement mortar, thereby improving the uniformity of the mixing of the admixture and the cement mortar.

[0026] The shaking of the rotating box will also drive the feeding pipe to shake synchronously in the shaking hole. At this time, the shaking of the feeding pipe can shake off the admixtures remaining in the feeding pipe, preventing the feeding pipe from adhering to the inner surface of the feeding pipe for a long time, which will cause the feeding pipe to discharge the admixture unsmoothly in the long run, ensuring that the admixtures added meet the ratio of cement mortar in the mixing drum, reducing the error in the cement mortar ratio caused by the residue of admixtures;

[0027] By disconnecting the meshing relationship between convex tooth 2 and convex tooth 1, part of the load can be released, and automatic disconnection can be achieved after the addition of the additive is completed, thereby reducing the load on the motor when driving, thereby achieving the effect of energy saving on the motor. In addition, due to the rolling action of the ball, the rotation of the rotating block 2 can be prevented from being stuck, the smoothness of the rotation of the rotating block 2 is improved, and the additional load on the motor caused by the undisconnected structure can be further reduced.

The inner part of the annular groove 51 at the bottom of the outer ring frame 41 is rotatably connected with an outer ring ring 52, and the lower surface of the outer ring ring 52 is fixedly connected with a plurality of power-assisting plates 55 arranged in a circular array, and the shape of each power-assisting plate 55 after rotation is adapted to the shape of the inner side surface of the mixing drum 1, so as to fit the mixing drum 1 The inner surface of the inner ring 43 rotates to ensure effective stirring of the mortar in the mixing drum 1, and the inner surface of each power-assisting plate 55 is fixedly connected to a plurality of flat plates for increasing the contact range with the mortar in the mixing drum 1. The inner ring groove 51 at the bottom of the inner ring frame 43 is rotatably connected to the inner ring 53, and the inner ring surface of the inner ring 53 is provided with a plurality of teeth arranged in a circular array, and the inner ring 53 is meshed with the second gear 47 through the teeth, and a plurality of connecting rods 54 arranged in a circular array are fixedly connected between the inner ring surface of the outer ring 52 and the outer ring surface of the inner ring 53.

[0051] like Figure 3 , Figures 6 to 9As shown, a feeding assembly for quantitatively and evenly rotating and feeding the admixture is provided at the top of the inner ring frame 43, and the feeding assembly includes a fixed frame 61 fixedly connected to the upper surface of the inner ring frame 43, and the fixed frame 61 is composed of four main rods and a platform. The outer surface of the four main rods of the fixed frame 61 is provided with a spring groove 62, and the bottom of the groove wall of the four spring grooves 62 is fixedly connected with a spring 1 63, and the top of the four spring 1 63 is fixedly connected with a movable rod 64, and the four movable rods 64 slide inside the spring groove 62, and the top of the four movable rods 64 is commonly fixedly connected with a fixed platform 65, and the top of the side wall of the four main rods of the fixed frame 61 is provided with symmetrical limiting grooves 66, and the bottom of the fixed platform 65 is fixedly connected with a limiting hook 67 corresponding to the position of each limiting groove 66, and the shape of the limiting hook 67 is L-shaped, and the bottom of the limiting hook 67 slides inside the corresponding limiting groove 66, which is used to stabilize the up and down movement of the fixed platform 65 while also preventing the upward movement of the fixed platform 65 from being too high and detaching.

[0052] like Figures 6 to 12 As shown, the feeding assembly also includes a rotating block 68 that is rotatably connected to the middle of the fixed platform 65 with a limited position, and the bottom of the rotating block 68 is fixedly connected to a convex tooth 69 arranged in a circular array, and the top of the rotating block 68 is fixedly connected to a rotating plate 610, and the upper surface of the rotating plate 610 is fitted with a rotating box 611, and the interior of the rotating box 611 is arranged as a circular cavity, and a circular groove 612 is provided at the top of the rotating box 611 and at the top of the circular cavity of the rotating box 611, and a circular hole is provided in the groove wall of the circular groove 612 for feeding the admixture, and a rotating hole is provided in the middle of the platform of the fixed frame 61, and a rotating block 2 613 is rotatably connected in the rotating hole in the middle of the platform of the fixed frame 61, and a tooth plate 614 is fixedly connected to the bottom of the rotating block 2 613, and the outer ring of the rotating block 2 613 A rolling groove is provided between the surface and the wall of the rotating hole groove in the middle of the platform of the fixed frame 61, and a ball 615 is rollingly connected between the rotating block 613 and the rolling groove of the fixed frame 61 platform. The ball 615 is used to assist the rotating block 613 in rotating. A groove is provided on the top of the rotating block 613, and a convex tooth 616 arranged in a circular array is fixedly connected in the groove of the rotating block 613. The convex tooth 616 and the convex tooth 69 are meshed with each other. A gear shaft 617 is fixedly connected to the top of one of the rotating shafts 46. The gear shaft 617 consists of a straight rod and a gear disk. The gear disk of the gear shaft 617 is meshed with the tooth plate 614, and the gear disk of the gear shaft 617 is smaller in diameter than the tooth plate 614, so that when the gear shaft 617 drives the tooth plate 614 to rotate, the tooth plate 614 rotates at a slower speed.

[0053] like Figure 3 , Figure 8 , Fig.11 and Fig.12As shown, the feeding assembly also includes a shaking hole 618 opened at the bottom of the rotating plate 610, and a feeding pipe 619 is fixedly connected to the bottom of the rotating box 611. The feeding pipe 619 passes through the shaking hole 618. The top of the feeding pipe 619 is connected to the annular cavity of the rotating box 611. The bottom of the feeding pipe 619 extends above the connecting rod 42, and the height of the upper surface of the mixing drum 1 is higher than the bottom end of the feeding pipe 619. It is used to prevent the admixture from leaking to the area outside the mixing drum 1 during the process of the feeding pipe 619 rotating to feed the admixture, so as to ensure that the admixture can be effectively fed into the inside of the mixing drum 1. The admixture inside the annular cavity of the rotating box 611 can be discharged to the connecting rod 42 through the feeding pipe 619. The gap between 42 and the outer ring frame 41 allows the admixture to fall into the interior of the mixing drum 1. The diameter of the shaking hole 618 is larger than the diameter of the feeding tube 619, so that there is a shaking space when the feeding tube 619 shakes. The upper surface of the mixing drum 1 is fixedly connected with a fixing rod 620, and the fixing rod 620 is set to be L-shaped. The top of the fixing rod 620 passes through the circular groove 612 and extends to the inside of the circular cavity of the rotating box 611. The top of the fixing rod 620 is slidably connected with a limiting plate 621, and the limiting plate 621 is located inside the circular cavity of the rotating box 611. The limiting plate 621 fits tightly with the groove wall of the circular cavity of the rotating box 611 to block the admixture.

[0054] like Figure 2 , Figure 6 , Fig. 9 and Fig.12 As shown, a shaking assembly is provided on the rotating plate 610, and two shaking grooves 71 symmetrically distributed about the rotating block 1 68 are opened at the bottom of the rotating plate 610, and springs 2 72 are fixedly connected to the inner groove walls on both sides of the two shaking grooves 71, and a shaking block 73 is fixedly connected between the two springs 2 72, and the shaking block 73 slides inside the shaking groove 71, and the top of the shaking block 73 is fixedly connected to the lower surface of the rotating box 611, and the bottom of the shaking block 73 is fixedly connected to a resistance rod 74, and the outer ring surface of the fixed platform 65 is fixedly connected to a resistance ring 75, and the outer ring surface of the resistance ring 75 is configured to be corrugated, and the resistance rod 74 resists against the resistance ring 75.

[0055] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0056] The initial state is:

[0057] No additive is put into the annular cavity of the rotating box 611, and the spring 1 63 is not squeezed. The spring 1 63 makes the fixed platform 65 in the highest position through the movable rod 64, so that the rotating block 1 68 drives the convex tooth 1 69 not to engage with the convex tooth 2 616 in the groove of the rotating block 2 613.

[0058] The working status is:

[0059] First, sand, gravel and cement are put into the hopper 3 through a transportation equipment such as a forklift or a conveyor belt that can transport sand, gravel and cement, and then discharged into the mixing drum 1 through the hopper 3. At this time, the admixture to be put into the mortar is first put into the annular cavity of the rotating box 611 through the existing weighing device. Under the action of the weight of the admixture, the rotating box 611 moves downward, and the rotating box 611 presses down the rotating plate 610. The rotating plate 610 will drive the fixed platform 65 to move downward through the rotating block 1 68. The fixed platform 65 drives the movable rod 64 to move downward in the spring groove 62 and compress the spring 1 63. In addition, the downward movement of the rotating block 1 68 will make the convex tooth 1 69 mesh with the convex tooth 2 616, so as to facilitate the subsequent rotating block 2 613 to drive the rotating plate 610 to rotate through the meshing relationship between the convex tooth 2 616 and the convex tooth 1 69.

[0060] The labor-saving component mixes the cement and sand and gravel put into the mixing drum 1:

[0061] The water source is injected into the working state, and then the motor 44 is started. The output shaft of the motor 44 drives the first gear 45 to rotate, and the first gear 45 drives the second gear 47 meshing therewith to rotate, and the second gear 47 drives the rotating shaft 46 to rotate on the inner ring frame 43. The second gear 47 also drives the stirring shaft 48 to rotate at the same time, so that the stirring shaft 48 can stir and mix the cement, sand and water in the mixing drum 1. The first gear 45 can share the transmission to the four second gears 47, so as to achieve the balance and sharing of the transmission, and then achieve the effect of saving labor, so as to achieve the purpose of energy saving for the motor 44. Through different rotation ratios, the speed of the second gear 47 can be faster than that of the first gear 45, and the rotation of the motor 44 can be effectively converted, so that the stirring shaft 48 can fully stir and mix the cement mortar in a short time, and the spiral stirring effect of the stirring shaft 48 can make the cement mortar form an up and down reflux in the mixing drum 1, effectively improving the mixing efficiency of the cement mortar.

[0062] The booster assembly assists the stirring shaft 48 to mix cement mortar:

[0063] During the rotation of the second gear 47, the second gear 47 will drive the inner ring 53 to rotate in the annular groove 51 at the bottom of the inner ring frame 43 through the teeth of the inner ring 53. During the rotation of the inner ring 53, the outer ring 52 will be driven to rotate in the annular groove 51 at the bottom of the outer ring frame 41 through the second connecting rod 54. The outer ring 52 drives the power plate 55 to rotate inside the mixing drum 1, thereby stirring the cement mortar inside the mixing drum 1, which can assist the flow of the cement mortar and avoid the ineffective flow and mixing of the cement mortar when too much cement mortar is stirred, thereby improving the effectiveness of the cement mortar mixing. In addition, by stirring the flowing cement mortar, the resistance of the cement mortar to the stirring shaft 48 can be further reduced, the load of the motor 44 can be reduced, and an efficient stirring effect can be achieved.

[0064] The feeding component evenly feeds the admixture into the cement mortar in the mixing drum 1:

[0065] During the rotation of the rotating shaft 46, the rotating shaft 46 engages with the toothed disc of the gear shaft 617 and drives the straight rod of the gear shaft 617 to rotate. The gear shaft 617 drives the toothed plate 614 to rotate through the toothed disc. The toothed plate 614 drives the rotating block 613 to rotate in the rotating hole of the fixed frame 61. In addition, under the rolling action of the ball 615 in the rolling groove between the rotating block 613 and the fixed frame 61, the rotating block 613 can rotate more smoothly, and the rotating block 613 can rotate more smoothly through the convex tooth 614. The meshing relationship between 16 and the convex tooth 69 drives the rotating block 68 to rotate in the middle of the fixed platform 65, and the rotating block 68 drives the rotating plate 610 to rotate. The rotating plate 610 drives the rotating box 611 to rotate synchronously through the shaking groove 71. During the rotation of the rotating box 611, the feeding pipe 619 is driven to rotate synchronously. At this time, the feeding pipe 619 is kept above the connecting rod 42 and rotates. Because the fixed rod 620 and the limit plate 621 remain stationary, the feeding pipe 619 is kept above the connecting rod 42. During the rotation of 611, the fixed rod 620 forms a sliding state in the circular groove 612. In addition, the rotating box 611 will also drive the admixture therein to rotate synchronously when it rotates. However, due to the limitation of the limit plate 621, the admixture will be blocked from effectively rotating synchronously with the rotating box 611, so that the limit plate 621 will form a blockage for the admixture. When the rotating box 611 drives the feeding pipe 619 to rotate to the admixture position, the admixture will fall downward from the connection between the feeding pipe 619 and the rotating box 611, so that the admixture can fall downward from the gap of the connecting rod 42 in a rotating state onto the cement mortar in the mixing drum 1 through the feeding pipe 619. By rotating the admixture, it can be avoided that the existing single-position delivery of the admixture cannot ensure that the admixture is evenly mixed with the cement mortar. The rotating delivery can make the admixture evenly delivered to the cement mortar, thereby improving the uniformity of the mixing of the admixture and the cement mortar, and further improving the production quality of the cement mortar.

[0066] Shake the assembly to avoid residual admixture:

[0067] During the rotation of the rotating plate 610, the rotating plate 610 will drive the shaking block 73 in the shaking groove 71 to rotate synchronously, and the shaking block 73 will drive the contact rod 74 to rotate synchronously. During the rotation of the contact rod 74, due to the interference relationship with the contact ring 75 and the wavy outer surface of the contact ring 75, the contact rod 74 will drive the shaking block 73 to shake inside the shaking groove 71 along the wavy surface of the contact ring 75. At this time, the shaking block 73 will continuously produce deformation, stretching and compression on the spring 2 72. During the shaking of the shaking block 73, the rotating box 611 will be driven to shake synchronously. In addition, the shaking of the rotating box 611 will The limiting plate 621 tightly fitted in its annular cavity is driven to shake synchronously on the top of the fixed rod 620. The shaking of the rotating box 611 will also drive the feeding pipe 619 to shake synchronously in the shaking hole 618. At this time, the shaking of the feeding pipe 619 can shake off the admixture remaining in the feeding pipe 619, thereby preventing the feeding pipe 619 from adhering to the inner surface of the feeding pipe 619 for a long time, which will cause the feeding pipe 619 to discharge the admixture unsmoothly in the long run, thereby ensuring that the added admixture meets the ratio of the cement mortar in the mixing drum 1, reducing the error in the cement mortar ratio caused by the residue of the admixture, and further ensuring that the cement mortar meets the production quality.

[0068] Release the meshing relationship between the second protruding tooth 616 and the first protruding tooth 69:

[0069] When the admixture in the annular cavity of the rotating box 611 is discharged, the rotating box 611 will reduce its weight. Under the elastic reset action of the spring 1 63, the movable rod 64 will move upward inside the spring groove 62, and the movable rod 64 will drive the fixed platform 65 to move upward, and the fixed platform 65 will drive the limiting hook 67 to move upward inside the limiting groove 66. The limiting groove 66 restricts the limiting hook 67, thereby preventing the fixed platform 65 from moving too high and disengaging. The fixed platform 65 will drive the rotating block 1 68 rotating in the middle thereof to move upward synchronously, and the upward movement of the rotating block 1 68 will drive the convex tooth 1 69 to be unable to mesh with the convex tooth 2 616. Even if the gear shaft 617 drives the tooth plate 614 to rotate, and the tooth plate 614 drives the rotating block 2 613 to rotate in the rotating hole of the fixed frame 61, the rotating block 2 613 cannot pass through the convex tooth 2 616. As the convex tooth 69 drives the rotating block 68 to rotate, the rotating block 68 no longer drives the rotating plate 610 to rotate. After the rotating plate 610 stops rotating, the rotating box 611 thereon also stops rotating, thereby stopping the addition of the admixture. In addition, the rotating plate 610 can remain stable through the interference relationship between the interference rod 74 and the interference ring 75, and will not shake at will. By releasing the meshing relationship between the convex tooth 2 616 and the convex tooth 69, part of the load can be released, and automatic disconnection can be achieved after the addition of the admixture is completed, thereby reducing the load on the motor 44 during driving, thereby achieving the effect of energy saving for the motor 44. In addition, due to the rolling action of the ball 615, the rotation of the rotating block 2 613 can be prevented from being stuck, thereby improving the smoothness of the rotation of the rotating block 2 613, and further reducing the additional load on the motor 44 caused by the undisconnected structure.

[0071] Step 1: Cement, sand and water are put into the mixing drum 1 in a ratio of 1:3.8:0.9, the motor 44 drives the second gear 47 to rotate through the first gear 45, and the second gear 47 drives the mixing shaft 48 to mix the mixed cement mortar;

[0072] Step 2: The first gear 45 causes the second connecting rod 54 to drive the outer ring 52 to rotate through the inner ring 53, and the outer ring 52 drives the power-assisting plate 55 to assist the cement mortar in the mixing drum 1 to flow and mix;

[0073] Step 3: Add the pipe column admixture water reducer, ground slag, silica fume, etc. into the rotating box 611 according to the proportion;

[0074] Step 4: When the rotating box 611 rotates, the admixture put into it is discharged downward onto the cement mortar through the feeding pipe 619, and the cement mortar is stirred by the stirring shaft 48 and the assisting plate 55, so that the admixture is mixed with the cement mortar;

[0075] Step 5: During the rotation of the rotating box 611 , the abutment rod 74 is caused to continuously shake due to the shape of the abutment ring 75 . The shaking of the rotating box 611 causes the feeding pipe 619 to shake, thereby preventing the residual admixture in the feeding pipe 619 .
