Description

Technical Field

[0001] The invention relates to the field of prefabricated pile production, and in particular to a prefabricated pile pumping material distribution device. Background Art

[0002] Precast concrete piles are precast concrete components with steel cages inside that are prefabricated in factories. At present, the production of precast piles generally adopts two processes, namely, the method of laying materials before closing the mold and the method of closing the mold before laying materials. The method of laying materials before closing the mold is a method of laying materials into the open mold manually or by a material truck. This method is slow, the product quality is greatly affected by human factors, and requires a lot of labor. In addition, during the laying process, the waste of concrete materials is very serious.

[0003] The method of closing the mold first and then distributing the material is an improvement on the method of distributing the material first and closing the mold later. For example, a precast pile pumping distribution method previously disclosed by the applicant makes the precast pile mold into a whole, and directly delivers concrete to the precast pile mold through the precast pile pumping distribution equipment. Its structure includes a concrete pump, a delivery pipe connected to the concrete pump for distributing the material to the precast pile mold, and a supporting trolley supporting the delivery pipe. The delivery pipe and the precast pile mold are arranged along the same straight line; the precast pile mold and the supporting trolley can reciprocate along the guide rail relative to the concrete pump, and the delivery pipe connected to the concrete pump extends into the precast pile mold to achieve distribution. Compared with the traditional distribution method, this distribution method significantly reduces material waste and improves efficiency.

[0004] However, during the material laying process, the delivery pipe will extend into the precast pile mold, resulting in concrete material attached to the outer wall of the delivery pipe. During the reciprocating motion of the precast pile mold relative to the delivery pipe, the concrete material attached to the outer wall of the delivery pipe will cause the following problems: concrete material accumulates at the material laying port of the precast pile mold, making it difficult for the delivery pipe to enter the precast pile mold; the delivery pipe with concrete material attached to the outer wall enters the precast pile mold again for material laying, resulting in gaps in the precast piles produced, thereby reducing the quality of the precast piles. Summary of the invention

[0005] The purpose of the present invention is to provide a precast pile pumping material distribution equipment with the function of cleaning the outer wall of the conveying pipe in view of the shortcomings of the prior art.

[0052] <Example 1>

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a precast pile pumping material distribution equipment 1, including a concrete pump (not shown in the figure), a delivery pipe 12, a movable cleaning device 10, a support platform 13 and a material receiving portion 14. The delivery pipe 12 is externally connected to the concrete pump for feeding materials to the precast pile mold 11; the support platform 13 is used to support the delivery pipe 12 and the movable cleaning device 10 and drive the movable cleaning device 10 to move; the material receiving portion 14 connects the support platform 13 and the precast pile mold 11 and is located below the movable cleaning device 10 to receive the scraped concrete material.

[0054] Specifically, the delivery pipe 12, the precast pile mold 11, the support platform 13 and the guide rail 2 are arranged along the same straight line direction, the precast pile mold 11 is loaded by a precast pile mold vehicle (not shown in the figure) and can reciprocate along the guide rail 2, and wheels 131 are arranged at the bottom of the support platform 13 for rolling back and forth on the guide rail 2, so that the movable cleaning device 10 fixedly connected to the support platform 13 and the delivery pipe 12 can have axial relative movement, so that the movable cleaning device 10 can scrape off foreign matter on the outer wall of the delivery pipe 12, avoiding the accumulation of attached concrete material at the mouth of the precast pile mold 11 or the delivery pipe 12 with concrete material attached to the outer wall entering the precast pile mold 11 during material laying, resulting in a decrease in the quality of the manufactured precast piles.

[0055] In this embodiment, the specific working process of the precast pile pumping distribution equipment 1 is as follows: precast piles are made, the precast pile mold 11 and the support platform 13 move synchronously toward the pump direction, and reach the distribution end of the precast pile mold 11. The concrete pump distributes the concrete to the precast pile mold 11 through the delivery pipe 12. During the distribution process, the precast pile mold 11 and the support platform 13 move away from the pump. At this time, the outer wall of the delivery pipe 12 will be attached with concrete material. The delivery pipe 12 passes through the movable cleaning device 10 arranged on the support platform 13, and the concrete material on the outer wall of the delivery pipe 12 is scraped into the material receiving part until the delivery pipe 12 reaches the mouth of the precast pile mold 11, and the distribution is completed.

[0056] Furthermore, Figure 1 and Figure 3 As shown, the movable cleaning device 10 has a central through hole 1014 for the delivery pipe 12 to pass through and the hole wall is always in contact with the outer wall of the delivery pipe 12. The movable cleaning device 10 circumferentially covers and closely fits the delivery pipe 12, and can effectively scrape away foreign matter at various locations around the delivery pipe 12.

[0057] like Figure 1 and Figure 3 As shown, the movable cleaning device 10 includes a cleaning part 101 and a movable connecting rod 102; the movable connecting rod 102 connects the cleaning part 101 and the support platform 13 in the length direction. When the cleaning part 101 and the conveying pipe 12 have relative axial movement, the movable connecting rod 102 can at least adjust the central axis direction of the central through hole 1014 according to the position change of any cross-sectional section on the conveying pipe 12 in the central through hole 1014 of the cleaning part 101 relative to the support platform 13.

[0058] In the above structure, the effect of the movable connecting rod 102 is reflected in that: since the conveying pipe 12 is a long tubular structure, and the conveying pipe 12 carries the concrete material, the centroid of each cross section of the conveying pipe 12 is very likely to be radially offset relative to the originally set centroid position due to the gravity or other environmental factors, so that the axis of the conveying pipe 12 becomes a curve. In this embodiment, when the cleaning part 101 moves axially relative to the conveying pipe 12 and / or the conveying pipe 12 moves axially relative to the cleaning part 101, the cleaning part 101 and the support platform 1 are respectively connected at both ends in the length direction. The movable connecting rod 102 of 3 can at least adjust the central axis direction of the central through hole 1014 according to the position change of any cross-sectional section on the conveying pipe 12 in the central through hole 1014 relative to the support platform; that is, the movable cleaning device 10 with the movable connecting rod 102 makes the clearance between the central through hole 1014 of the cleaning part 101 and the radial clearance of the outer wall of the conveying pipe 12 tend to be equal or evenly fitted, so that the outer wall of the conveying pipe 12 can be prevented from being scratched by the movable cleaning device 10, and foreign matters at the radial clearance of the outer wall of the conveying pipe 12 can be effectively scraped off, thereby improving the cleaning quality.

[0059] Specifically, in order to achieve the effect that the movable connecting rod 102 adjusts the central axis direction of the central through hole 1014 according to the position change of any cross-section on the conveying pipe 12 relative to the support platform 13 in the central through hole 1014, the connection mode between the cleaning part 101 and the movable connecting rod 102 is hinged. In this embodiment, the hinged form adopts the pin 103 connection, of course, other hinged forms can also be adopted. Adding a gasket 1031 between the pin 103 and the movable connecting rod 102 can play a role in increasing the connection strength.

[0060] Preferably, the cleaning part 101 is connected to the support platform 13 by hinged connection. The movable connecting rod 102 structure with hinged ends enables the movable connecting rod 102 to change not only the direction of the central axis of the central through hole 1014 of the cleaning part 101 but also the vertical position of the central axis.

[0061] like Figure 4 and 5 As shown, in this embodiment, the cleaning section 101 includes a connecting section 1011 hinged to one end of the movable connecting rod 102 and a cleaning section 1012 connected to the connecting section 1011; the inner contour of the cleaning section 1012 is consistent with the outer contour of the conveying pipe 12, wherein the inner diameter of the connecting section 1011 is larger than the inner diameter of the cleaning section 1012, and the cleaning section 1012 is in contact with the outer diameter of the conveying pipe 12 at the smallest inner diameter.

[0062] Specifically, the cleaning section 101 is cylindrical, and the connecting section 1011 and the cleaning section 1012 are an integral structure. Of course, the connecting section 1011 and the cleaning section 1012 can also be connected by other mechanical means (such as screw connection, clamping connection, plug connection, etc.). The connecting section 1011 is symmetrically provided with mounting holes 1013 for connecting with the movable connecting rod 102 around the central axis. The symmetrically distributed mounting holes 1013 structure is conducive to evenly distributing the thrust force transmitted from the cleaning section 1012 to each movable connecting rod 102. The inner diameter of the connecting section 1011 is larger than the inner diameter of the cleaning section 1012. Preferably, in order to reduce the difficulty of cleaning, the wall thickness of the cleaning section 1012 is gradually reduced to form a sharp cleaning opening 1012a with a blade.

[0063] In order to thoroughly scrape off the foreign matter on the outer wall of the delivery pipe 12, in this embodiment, the inner diameter of the cleaning port 1012a is fitted with the outer diameter of the delivery pipe 12. Theoretically, when they are fitted, the inner diameter of the cleaning port 1012a can completely remove the foreign matter on the outer wall of the delivery pipe 12. However, considering that during the relative movement between the delivery pipe 12 and the cleaning port 1012a, if the cleaning port 1012a and the delivery pipe 12 are in zero-gap contact, a certain friction force will be generated, thereby causing a certain wear on the delivery pipe 12, and it is also not conducive to the smooth movement between the cleaning port 1012a and the delivery pipe 12. Therefore, according to the actual situation, there can be a certain small gap between the inner diameter of the cleaning port 1012a and the outer diameter of the delivery pipe 12, and the small gap is smaller than the particle size of the foreign matter, so as to prevent the foreign matter from entering between the cleaning port 1012a and the delivery pipe 12.

[0064] like Figure 6 As shown, it is a schematic diagram of the structure of the movable connecting rod 102 of this embodiment. The movable connecting rod 102 is a flat plate-like structure with connecting holes 1021 at both ends. The two ends are respectively hinged to the cleaning part 101 and the supporting platform 13, and the cleaning part 101 is fixed on the supporting platform 13. The supporting platform 13 has relative movement with the conveying pipe 12 along the axial direction of the conveying pipe 12.

[0065] like Figure 4 and Figure 5 As shown, the cleaning portion 101 is provided with a cutout 1015 along the axial direction, and the cutout 1015 passes through the cleaning portion 101 .

[0066] In the above structure, by setting the cutout 1015 that passes through the cleaning part 101, the cleaning part 101 can produce a certain radial and / or circumferential deformation, which not only increases the versatility of the conveying pipes 12 with similar outer diameters, but also can adapt to the situation where the roundness deformation of each cross section of the conveying pipe 12 occurs; it can also cooperate with the hinge structure of the above-mentioned movable connecting rod 102 to better adapt to the deformation of the conveying pipe 12 and reduce the wear of the conveying pipe 12 and the cleaning part 101.

[0067] like Figure 1 and Figure 2 As shown, the movable cleaning device 10 is hinged to a fixed support 133 on the support platform 13 , and a material receiving portion 145 is also provided on the support platform 13 .

[0068] like Figure 1As shown, in this embodiment, the material receiving portion 14 connects the support platform 13 and the precast pile mold 11, and is fixedly connected to the support platform 13 and the precast pile mold 11 (or the precast pile mold vehicle). There are many connection methods that can be used, such as welding, screw connection, etc., which are not limited here, as long as the support platform 13 and the precast pile mold 11 are ensured to move synchronously. The material receiving portion 14 is located below the movable cleaning device 10 to receive the scraped concrete material to prevent the scraped concrete material from falling everywhere, affecting the workshop environment, or scattering on the guide rail and around the guide rail to cause the support platform 13 to derail. In addition, within the scope of installation, the width of the material receiving portion 14 is greater than the diameter of the conveying pipe 12 of the precast pile mold 11 to ensure that the scraped concrete material can fall into the material receiving portion 14; the concrete material received in the material receiving portion 14 can be conveyed by a conveyor belt or manually removed or recycled.

[0069] Further, such as Figure 1 and Figure 2 As shown, a positioning mechanism 134 is provided on the support platform 13 for maintaining the moving direction of the conveying pipe 12 when the conveying pipe 12 extends into the precast pile mold 11. Specifically, the positioning mechanism 134 includes a roller 1341 and a roller bracket 1342, the roller bracket 1342 is welded on the support platform 13, the roller 1341 is vertically nested on the roller bracket 1342, so that the roller 1341 can make a circular motion with its own axis as the axis, the rollers 1341 are symmetrically arranged on both sides of the conveying pipe 12, the outer wall of the conveying pipe 12 is in rolling contact with the rollers 1341 on both sides, and the conveying pipe 12 passes through the central through hole 1014 of the movable cleaning device 10 and is tangent to the rollers 1341 on both sides. Since the conveying pipe 12 has a long axial length, if there is no positioning mechanism 134 to position the conveying pipe 12 during the feeding process, the conveying pipe 12 is very likely to deviate from the original direction of travel and collide with the precast pile mold 11, the movable cleaning device 10, etc., causing wear between the components; further, the positioning mechanism 134 is in rolling contact with the conveying pipe 12, reducing the friction resistance and friction damage to the conveying pipe 12 during the positioning process, and after the concrete attached to the outer wall of the conveying pipe 12 that has not been cleaned by the movable cleaning device 10 solidifies, the roller 1341 of the positioning mechanism 134 can crush the solidified concrete.

[0070] In addition, in view of the fact that concrete is easy to solidify, the precast pile pumping distribution equipment 1 provided by the present invention can achieve cleaning while distributing the concrete, which not only improves the cleaning efficiency, but also scrapes off the concrete on the outer wall of the delivery pipe 12 when the concrete is not solidified, thereby reducing the difficulty of cleaning and recycling the scraped concrete.

[0071] In addition, the precast pile pumping material distribution equipment 1 provided by the present invention utilizes the power of the precast pile mold loader to drive the support platform 13 to move as the power of the movable cleaning device 10, so that the movable cleaning device 10 and the conveying pipe 12 can move relative to each other, without providing additional power or manual operation, thus saving energy and labor costs.

[0072] <Example 2>

[0073] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0074] like Figure 7 and Figure 8 As shown, compared with the first embodiment, the precast pile pumping material placing equipment 1 provided in this embodiment further includes a connection control device 15 for controlling the combination and separation of the support platform 13 and the precast pile mold 11 .

[0075] Specifically, Figure 7 and Fig. 9 As shown, the connection control device 15 includes a driving mechanism 151 and a clamping mechanism 152. The driving mechanism 151 is hingedly fixed to the support ear 132 on the support platform 13, so that the driving mechanism 151 can make a circular motion at the hinge point with the support ear 132; the clamping mechanism 152 includes a clamping arm 1521 and a hook ear 1522. One end of the clamping arm 1521 is hingedly connected to the power output end of the driving mechanism 151, and the middle part of the clamping arm 1521 is hingedly connected to the support platform 13. The fixed support 133 is hinged, and the other end of the clamp arm 1521 is provided with a hook ear 1522 that can be engaged with the precast pile mold 11. When the driving mechanism 151 is working, the power output end of the driving mechanism 151 drives the clamp arm 1521 to make a circular motion around the hinge point between it and the fixed support 133, and controls the clamping or loosening of the hook ear 1522 on the precast pile mold 11, thereby realizing the combination and separation of the support platform 13 and the precast pile mold 11. In this embodiment, the driving mechanism adopts a pneumatic drive-cylinder or a hydraulic cylinder, and other driving forms, such as electrical drive, can also be adopted.

[0076] In this embodiment, the specific working process of the prefabricated pile pumping material distribution equipment 1 is as follows: during the prefabricated pile production, the driving mechanism 151 of the connection control device 15 drives the clamping mechanism 152 to open, the prefabricated pile mold 11 approaches the support platform 13, contacts and pushes the support platform 13 to move synchronously in the pump direction, and the delivery pipe 12 passes through the central through hole 1014 of the movable cleaning device 10 and extends into the prefabricated pile mold 11 until the delivery pipe 12 reaches the end of the prefabricated pile mold 11 away from the pump direction, and the delivery pipe 12 starts to distribute the material. At this time, the connection control device 15 is turned on. The driving mechanism 151 of the control device 15 drives the clamping mechanism 152 to clamp the precast pile mold 11, and the precast pile mold 11 drives the support platform 13 to move away from the pump synchronously. The movable cleaning device 10 and the conveying pipe 12 have relative motion, and the cleaning port 1012a scrapes the concrete material on the outer wall of the conveying pipe to the material receiving portion 14. When the conveying pipe 12 reaches the end position of the precast pile mold 11, the driving mechanism 151 drives the clamping mechanism 152 to open, and the support platform 13 is separated from the precast pile mold 11. At this point, the material distribution is completed. Of course, in the entire material distribution process, as long as the conveying pipe 12 and the movable cleaning device 10 have relative motion, the outer wall of the conveying pipe 12 can be scraped.

[0077] Compared with the first embodiment, in this embodiment, the material receiving portion 14 is only fixed on the supporting platform 13, and the connection relationship between the supporting platform 13 and the precast pile mold 11 is controlled by the connection control device 15. This method is not only conducive to the maintenance and replacement of components, but also because the connection relationship between the supporting platform 13 and the precast pile mold 11 is controllable, the actual production range that can be applied is larger.

[0078] <Example 3>

[0079] In this embodiment, the same parts as those in Embodiment 1 or 2 are given the same figure marks, and the same text descriptions are omitted.

[0080] Based on the above embodiments, further improvements can be made. Fig.10 and Fig.12 As shown, the cleaning section 1012 is annular, and is formed by connecting a plurality of arc-shaped pieces end to end, and the cleaning section 1012 is made of rubber.

[0081] In the above structure, the cleaning section 1012 is a split structure. Specifically, the cleaning section 1012 is a rubber ring with a central through hole 1014 formed by connecting four rubber sheets 1012b end to end. The split structure has a better radial deformation than the integrated structure, and can better adapt to the position change of any cross-section on the conveying pipe 12 relative to the support platform in the central through hole 1014, thereby reducing the wear on the pipe wall of the conveying pipe 12. As a preferred embodiment, the cleaning section 1012 is made of an elastic rubber material, which can adapt to a certain deformation of the conveying pipe 12, and the rubber material has a certain friction force, which can better scrape off foreign matter on the outer wall of the conveying pipe 12.

[0082] Furthermore, if Fig.10 As shown, the movable cleaning device 10 provided in this embodiment also has the following structure: a guide portion 104 connected to the cleaning portion 101. The guide portion 104 is in a conical shape with an inner diameter increasing from the end connected to the cleaning portion 101 to the end away from the cleaning portion 101.

[0083] like Fig.12 Hehe Fig.13 As shown, in this embodiment, an external thread (not shown in the figure) is provided at one end of the small inner diameter of the guide portion 104, which is threadedly connected to the connecting section 1011, so that the guide portion 104 is fixedly connected to the cleaning portion 101, and four axial grooves 1042 corresponding to the number of rubber sheets 1012b are provided along the inner circumferential wall of the guide portion 104 around the central axis, and a threaded hole 1041 for installing a rubber ring is provided between each axial groove 1042.

[0084] Compared with the first and second embodiments, the guide portion 104 of the movable cleaning device 10 provided in this embodiment can collect the foreign matter on the outer wall of the delivery pipe scraped off by the cleaning portion 101 to a designated collection point, thereby preventing the foreign matter on the outer wall of the delivery pipe from being scattered around and affecting the working environment.
