Description

Technical Field

[0001] The invention relates to the technical field of pipe pile production and processing, and in particular to a pipe pile distribution hopper. Background Art

[0002] With the rapid development of my country's construction, the demand for pipe piles has greatly increased. When producing pipe piles, concrete materials need to be placed in a mold equipped with a pipe pile reinforcement cage. However, during the current material distribution and feeding, it is difficult for the concrete materials to be completely distributed in the mold, which will cause part of the concrete materials to fall on the mold reinforcement plates on both sides of the mold under the pipe pile and the ground. Then, the concrete materials are manually shoveled from the ground and the mold edge, piled up and compacted; this will cause the following problems: 1. When the concrete materials are piled up and compacted, they will basically exceed the inner diameter height of the upper mold of the mold; when the upper and lower molds are closed, the higher part of the concrete collapses under pressure and falls to the mold edge, making it impossible for the upper and lower molds to be completely buckled; a. When the mold is separated a. When the centrifugal force rotates at high speed, concrete is easily thrown out of the gap, causing slurry leakage and producing defective or waste products; b. Because the upper and lower molds are not fully engaged, the mold wheel is out of round. When the mold rotates at high speed, it is easy to cause mold jumping, affecting the quality of concrete molding, and even the mold flies out and causes serious safety accidents; c. The mold clamping part is not fully engaged and centrifugal mold jumping will greatly promote mold deformation; 2. The concrete that falls to the ground is not completely scooped up and placed into the mold according to each mold one by one, which will cause the pipe pile to have less material and the quality problem of insufficient wall thickness of the pipe pile; therefore, pipe pile companies generally increase the material input to solve the quality problem of insufficient material, which greatly increases the product cost.

DETAILED DESCRIPTION

[0057] Embodiment 1

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 4The figure shows the pipe pile distribution hopper disclosed in the present invention, including two side plates 10 arranged opposite to each other, a distribution cavity is formed between the two side plates, the distribution cavity is opened at the top and the bottom to form a material dropping channel, the side plates 10 can slide and spread concrete materials when the distribution hopper moves axially relative to the pipe pile bottom mold in the pipe pile bottom mold, and the two ends of the distribution cavity are provided with a first pressing structure 2 for spreading and pressing concrete materials when the distribution hopper moves axially relative to the pipe pile bottom mold in the pipe pile bottom mold, and the first pressing structure 2 is provided with a first pressing surface 22, and the side of the first pressing surface 22 away from the distribution cavity is inwardly contracted relative to the side close to the distribution cavity, so that when the distribution hopper distributes materials along the axial direction of the pipe pile mold, the first pressing surface can spread and press the concrete materials falling on the pipe pile bottom mold. Specifically, this embodiment includes a forming bucket 1, which includes two oppositely arranged side plates 10 and end plates 11 arranged at both ends of the side plates 10. The lower parts of the two side plates 10 can be respectively inserted into the gaps 73 on the corresponding sides between the receiving pipe pile reinforcement cage 70 and the pipe pile lower mold 71. The upper end of the forming bucket 1 is a feed port 12, and the lower end is a discharge port 13. The forming bucket 1 is provided with a first pressing structure 2 at both ends of the end plates 11, which can be used to spread and press concrete material (usually concrete with a slump of 40-60 mm) falling on the receiving pipe pile reinforcement cage.

[0059] Specifically, Figure 5a and Figure 5b As shown, the side plate 10 includes a feed portion 100, a discharge portion 101 and a stopper portion 120 connected in sequence. Figure 3 and Fig.18 As shown, the feed parts 100 of the two side plates 10 are relatively arranged to form the feed port 12, and the discharge parts 101 of the two side plates 10 are relatively arranged to form the discharge port 13. Preferably, the feed part 100 and the discharge part 101 are at a certain angle, so that the feed port 12 is a structure that gradually closes from top to bottom, and the discharge port 13 is a structure that gradually opens from top to bottom to facilitate receiving concrete material and distributing the concrete material into the lower mold of the pipe pile and the steel cage. The blocking part 102 is at a certain angle to the discharge part 101, so that the blocking part 102 can be inserted into the gap 73 between the steel cage of the receiving pipe pile and the lower mold of the pipe pile. The discharge part and the blocking part can prevent the concrete material from falling from both sides to the edges of both sides of the lower mold of the pipe pile during distribution. Reinforcing ribs 16 are also provided on the outer wall of the forming bucket body.

[0060] Since the concrete material used for the pipe piles is dry hard concrete (concrete with a slump of 40-60mm), when the concrete material falls from the pipe pile distribution hopper onto the steel cage, it is cut by the steel bars, and the porosity of the concrete entering the mold is relatively high, so that the concrete accumulation height is relatively high. The concrete material accumulated by the traditional distribution device will partially collapse and fall onto the edges of both sides of the mold under the pipe pile or fall outside the mold. In the present invention, the pipe pile distribution hopper is provided with a first pressing structure for smearing and pressing the concrete material falling onto the steel cage. Specifically, the first pressing structure 2 is a pressing plate 20, and the pressing plate 20 is arranged at both ends of the forming bucket 1 provided with the end plate 11, such as Figure 6a and Figure 6b As shown, the lower part of the pressing plate 20 is provided with an arc-shaped groove 21 that can match the shape of the steel cage of the receiving pipe pile. The arc-shaped groove 21 is close to the first pressing surface 22 on the side of the discharge port 12. The first pressing surface 22 is an arc-shaped surface or an inclined surface, so that the arc-shaped groove gradually closes from one end of the discharge port to the other end. When distributing materials to the lower mold of the pipe pile and the steel cage, the lower mold of the pipe pile drives the steel cage to move relative to the pipe pile distributing bucket disclosed in the present invention. When the concrete material falls from the discharge port onto the steel cage, the steel cage and the pipe pile distributing bucket are in contact with each other. The movement causes the first pressing surface 22 on the pressing plate to spread and press the concrete material falling on the steel cage, generating vertical pressure on the concrete material and increasing the contact area between the side plate of the forming bucket and the material, making the smoothing contact area larger and enhancing the smoothing effect. Under the pressure of the first pressing surface, the surface layer of the concrete material formed when it is placed in the mold has a low porosity and is more compacted, eliminating the collapse of the concrete material falling on the steel cage, and further eliminating the problem of the concrete material falling to the edges of both ends of the mold under the pipe pile due to collapse.

[0061] The pressing plate 20 can be fixed at both ends of the forming bucket. When the pressing plate is fixed at both ends of the forming bucket, the contour line of the arc-shaped groove of the pressing plate is smaller than the contour line formed by the discharge port. Since the contour of the arc-shaped groove is smaller than the contour line formed by the discharge port, more concrete material falls on the steel cage. When the concrete material passes through the first pressing surface, the pressing surface can exert a greater spreading pressure on the concrete material, thereby improving the spreading pressure effect of the concrete material.

[0062] Furthermore, the forming hopper 1 is provided with a press plate accommodating cavity 14 at both ends of the end plate 11, the press plate 20 is placed in the press plate accommodating cavity 14, and a vibrator 23 is fixed to the top of the press plate 20, preferably an air vibrator, and the vibrator 23 can drive the press plate 20 to vibrate up and down in the press plate accommodating cavity 14. Figure 6bAs shown, the arc groove also includes a second pressing surface 24 and a third pressing surface 25. The second pressing surface 24 is located on the side of the arc groove opposite to the first pressing surface 22. Preferably, the second pressing surface is an arc surface or an inclined surface, so that the side of the arc groove provided with the second pressing surface is a gradually contracted structure. The third pressing surface 25 is a plane connecting the first pressing surface and the second pressing surface. The pressing plate is placed in the pressing plate accommodating cavity, and the vibrator on the pressing plate can drive it to vibrate up and down in the pressing plate accommodating cavity, so that when the concrete material falling from the discharge port onto the steel cage passes through the pressing plate, it is not only pressed by the first pressing surface, but the vibration of the pressing plate driven by the vibrator not only increases the pressing pressure of the first pressing surface, but also the third pressure surface can also press the concrete material, further improving the pressing effect, and effectively eliminating the problem of the concrete material collapsing and falling to the edges of both sides of the mold under the pipe pile. The pressing plate is provided with a second pressing surface, which can press the concrete material in both directions when the steel cage is reciprocated. Furthermore, since the vibrator is fixed on the pressing plate, the vibrator will only drive the pressing plate to vibrate when it vibrates, which can effectively avoid the problem that when the vibrator acts on the entire forming bucket, the moisture in the concrete material is separated from the material due to vibration, thereby affecting the quality of the concrete material.

[0063] Furthermore, the two ends of the forming bucket body are also provided with a second pressing structure for smearing and pressing the concrete material at the connection position between the discharge part 101 and the blocking part 102 on the steel cage falling into the receiving pipe pile, such as Figure 8a , Figure 8b and Figure 8cAs shown, the second pressing structure includes a fixing portion 30, a fifth pressing surface 31 and a fourth pressing surface 33, the fifth pressing surface 31 and the fourth pressing surface 33 are connected, the fifth pressing surface 31 is coplanar with the inner side surface of the discharge portion 101, and the second pressing structure is welded to the lower part of the end of the forming bucket body (specifically, the lower part of the discharge portion and the position of the stop portion) through the fixing portion 30, and one side edge of the fourth pressing surface 33 is a connecting edge connected to the inner side surface of the connection between the discharge portion 101 and the stop portion 102, and the middle part of the other side edge of the fourth pressing surface 33 is converged inwardly relative to the connecting edge, and the convergence of the middle part inwardly means that the upper and lower end points of the edge remain unchanged relative to the connecting edge, and the line between the two end points is converged inwardly relative to the connecting edge. In this embodiment, a smooth past curved surface is formed between the two edges. The material stopper 102 is inserted into the gap between the steel cage of the receiving pipe pile and the lower mold of the pipe pile. In this embodiment, the material stopper is preferably set as a vertical baffle structure. Since there is a certain angle between the discharge part and the material stopper, when the concrete material enters the space formed by the discharge part, the material stopper and the steel cage, the concrete material is easy to form a certain angle at the connection position of the discharge part and the material stopper. The concrete material of this shape is easy to collapse and fall on the edges of both sides of the lower mold of the pipe pile. A second pressing structure is provided, and the fourth pressing surface of the second pressing structure is a smooth curved surface that gradually converges toward the steel cage. The concrete material with a sharp angle formed at the connection between the discharge part and the material stopper can be further smoothed and pressed, eliminating the sharp angle structure, and further avoiding the collapse of the concrete material. The first pressing structure 2, the side plate 10 and the second pressing structure perform all-round sliding and pressing of the concrete material falling into the bottom mold of the pipe pile (including falling on the steel cage), so that after the concrete material is placed by the distribution hopper described in this embodiment, the prone-to-collapse areas are eliminated, and the problem of concrete falling due to loose and unformed material is solved, thereby realizing the fully automated production of pipe piles, greatly improving production efficiency, reducing labor, reducing the probability of mold deformation, and ensuring the quality of mold closing.

[0064] Furthermore, it also includes a forming bucket frame 4 and a forming bucket width adjustment device 5, such as Figure 9a and Figure 9b As shown, the forming bucket frame 4 includes two sets of vibration frames 40 arranged opposite to each other and vibration frame connecting members 41 for connecting the two sets of the vibration frames 40. The vibration frames 40 are located at both ends of the forming bucket, and the vibration frame connecting members 41 are located on both sides of the forming bucket. Fig.10a , Fig.10b , Fig.10c as well as Fig.10dAs shown, the vibration frame 40 includes a first fixing plate 400, a second fixing plate 401, a third fixing plate 402, a fourth fixing plate 403 and a fifth fixing plate 404. The first fixing plate 400 is horizontally arranged, and two second fixing plates 402 are respectively fixed on both sides of the first fixing plate 400, the third fixing plate 402 is fixed to the front end of the first fixing plate 400, and the fourth fixing plate 403 is fixed to the lower side of the first fixing plate 400. The fourth fixing plate has an arc-shaped groove matching the shape of the steel cage, and the two fifth fixing plates 404 are relatively arranged and fixed to the lower side of the first fixing plate 400 and are located on the side of the fourth fixing plate 403 facing the forming bucket. The two ends of the side of the fourth fixing plate 403 facing the forming bucket are respectively fixedly connected to the vibrator connecting member 41. Specifically, as shown in FIG. Fig.11a and Fig.11b As shown, the vibration frame connecting member 41 includes a sixth fixing plate 410 and a seventh fixing plate 411. The seventh fixing plate 411 is a long strip. There are one or more seventh fixing plates. In the figure, there are two seventh fixing plates. The two seventh fixing plates are arranged in parallel. The sixth fixing plates 410 are fixed to both ends of the seventh fixing plate 411 respectively. The sixth fixing plate 410 is fixedly connected to the fourth fixing plate 403. The forming bucket is installed in the forming bucket frame, as shown in FIG. Fig.12 As shown, the space enclosed by the first fixing plate 400 , the fourth fixing plate 403 , the two fifth fixing plates 404 and the end plate 11 forms the press plate accommodating chamber 14 , and a press plate replacement port 405 is provided on the first fixing plate at a position opposite to the press plate.

[0065] like Fig.13a , Fig.13b , Fig.14a , Fig.14b and Fig.14c As shown, the end plate 11 includes two first end plates 110, and the two first end plates 110 are respectively fixed on the two side plates 10. The side plates 10 and the first end plates 110 fixed at both ends of the side plates 10 form a forming bucket assembly 15. The two groups of the forming bucket assemblies 15 are installed on the forming bucket frame 4 through the forming bucket width adjustment device 5. The distance between the two groups of the forming bucket assemblies can be adjusted by the forming bucket width adjustment device. Specifically, as Fig.15As shown, the forming bucket width adjustment device 5 includes two groups of guide rods 50 installed on the forming bucket frame 4 and guide blocks 51 fixed on the first end plate 110. The two ends of the guide rods are installed with connecting blocks 54. The connecting blocks 54 are fixedly connected to the second fixing plates 401 on the corresponding sides, so that the guide rods are fixed on the forming bucket frame, and the forming bucket assembly is installed on the guide rods through the guide blocks. The guide blocks can move on the guide rods, and then the distance between the two groups of forming bucket assemblies can be adjusted. The guide blocks 51 are provided with locking screws 53, and the guide rods are provided with multiple groups of locking holes 500. The guide blocks 51 can move on the guide rods 50 and be locked at different locking hole positions by the locking screws 53.

[0066] like Fig.16 and Fig.19 As shown, the forming bucket frame 4 is also provided with a forming bucket lifting device for lifting the forming bucket 1, and the forming bucket lifting device includes a lift mounting seat 60 and a lift 63. In one embodiment, the lift 63 is a worm lift;

[0067] The elevator mounting seat 60 is installed on the forming bucket frame, and a worm fixing hole is provided on the elevator mounting seat 60. The worm of the worm elevator is fixed to the elevator mounting seat through the worm fixing hole. The driving device of the worm elevator is installed on the unloading device 9. The driving device can drive the worm to rise or fall, thereby realizing the rise or fall of the pipe pile distribution bucket. At the same time, since the pipe pile distribution bucket of the present invention is driven to rise and fall by the worm, the worm realizes a hard connection between the pipe pile distribution bucket and the unloading device, avoiding the problem of soft connection drive between the pipe pile distribution bucket and the unloading device. When there is too much concrete material at the discharge port in the pipe pile distribution bucket, the pipe pile distribution bucket will be lifted up by the concrete material, causing the concrete material to scatter.

[0068] Preferably, if Fig.16 and Fig.17As shown, the elevator mounting seat 60 is installed on the forming bucket frame 4 through a connecting pin assembly 8, and the connecting pin assembly 8 includes a ball head bolt 80, a spring 81, an elastic gasket 82 and a nut 83.

The ball head bolt 80 passes through the groove hole 62 and the bolt fixing hole 406 and is fixed by the nut 83. The elevator mounting seat 60 and the forming bucket frame 4 are connected. The spring 81 is arranged between the forming bucket frame 4 and the nut 83, and the spring 81 is sleeved on the ball stud 80. The elastic gasket 82 is arranged between the forming bucket frame 4 and the nut 83. When the pipe pile distribution bucket contacts the lower mold of the pipe pile, the spring can play a buffering role. At the same time, the ball stud is adopted, and the ball stud can realize the relative rotation of the pipe pile distribution bucket and the pipe pile reinforcement cage (the ball stud can realize 360° rotation), which can facilitate adjustment when the pipe pile distribution bucket (center line of the discharge port) is not parallel to the pipe pile reinforcement cage (axis line), so that the pipe pile distribution bucket is parallel to the pipe pile reinforcement cage. Since a forming bucket width adjustment device and a forming bucket lifting device are provided, the width of the forming bucket discharge port and the height between the discharge port and the steel cage can be adjusted. At the same time, a pressure plate replacement port is provided at a position opposite to the pressure plate on the first fixed plate, and pressure plates with different arc groove sizes can be replaced. Therefore, when casting pipe piles of different diameters, the device can be used to effectively eliminate the problem of concrete material falling onto the edges of both sides of the mold under the pipe pile. In order to solve this problem, in addition to setting the pressure plate in a replaceable form, it can also be set in a size-adjustable form to meet the processing needs of pipe piles of different diameters.

[0069] Furthermore, a handle 74 is provided on the pressing plate to facilitate replacement of pressing plates of different sizes. The pressing plates of different sizes only have different sizes of arc-shaped grooves of the pressing plates to meet the requirements of different pipe diameters.
