Description

Technical Field

[0001] This utility model belongs to the field of pipe pile preparation technology, and in particular relates to a vibratory compaction device for preparing concrete pipe piles. Background Technology

[0002] Vibration devices for concrete pipe pile preparation are key equipment in the production process of concrete pipe piles. They are used to remove air bubbles inside the concrete and improve the encapsulation of aggregates and reinforcing steel skeletons by vibration during concrete pouring and molding, thereby improving the density and uniformity of various parts of the pipe pile cross-section. Existing concrete pipe pile vibration devices mostly use eccentric vibration systems as vibration sources. Typically, a motor drives a rotating shaft equipped with an eccentric block to rotate at high speed. The unbalanced centrifugal force generated by the rotation drives the vibration components to produce high-frequency, small-amplitude reciprocating vibrations, which are then transmitted to the pipe pile mold and the concrete inside.

[0003] In large or long concrete pipe pile molds, the concrete cross-section is large, the mold length is long, and the structure is relatively complex. A single vibration point or a limited number of vibration positions often cannot effectively cover the vibration energy to the entire length and circumference of the pipe pile mold in a timely and uniform manner. This can easily lead to inconsistent vibration effects at different locations and insufficient vibration in some areas. Consequently, air bubbles in these areas cannot be discharged in time, and the fluidity and redistribution of the slurry are insufficient. As a result, after the concrete is formed, it is easy to have appearance defects such as low local density, uneven strength distribution, and even honeycomb surface. Because the vibration devices in related technologies generally adopt a single vibration point arrangement and lack targeted optimization control of the transmission and distribution of vibration energy in large pipe pile molds, quality defects such as honeycomb surface, insufficient density, and uneven internal quality are prone to occur in some areas when large concrete pipe piles are formed. Utility Model Content

[0004] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A vibratory device for preparing concrete pipe piles includes a vibratory assembly and two lateral support assemblies arranged symmetrically on the left and right sides.

[0007] The vibrating assembly is arranged between the two lateral support assemblies and is used to support and vibrate the bottom of the concrete pipe pile mold placed thereon.

[0008] The vibration assembly includes at least two vibration actuators, a vibration support, and an elastic pad layer laid on the upper surface of the vibration support, all distributed along the axial direction of the pipe pile mold. The output ends of the plurality of vibration actuators are connected to the vibration support.

[0009] Each of the lateral support components includes a lateral support seat elastically connected to the mounting base via multiple buffer components, and a rolling support member disposed on the upper end face of the lateral support seat for rolling engagement with the outer circular sidewall of the pipe pile mold.

[0010] Furthermore, it also includes two limiting components arranged symmetrically on the left and right sides. Each limiting component is arranged on the outside of the corresponding lateral support component and includes a limiting support and a limiting rod connected to the limiting support. The limiting rod is arranged along the axial direction of the pipe pile mold and is located on the outside of the outer circle side of the pipe pile mold, and is used to limit the radial displacement of the pipe pile mold during vibration.

[0011] Furthermore, the cross-section of the vibration support is an I-shaped structure.

[0012] Furthermore, the elastic pad is a rubber pad.

[0013] Furthermore, the vibration actuator is a vibration cylinder, and two vibration cylinders are provided, which are arranged symmetrically back and forth along the length direction of the vibration support.

[0014] Furthermore, the upper end face of the lateral support seat of each of the lateral support components is an arc-shaped support surface facing the vibrating component, and the arc-shaped support surface is provided with an installation groove extending along the axial direction of the pipe pile mold.

[0015] The rolling support includes a rotating shaft rotatably disposed in the mounting groove and a plurality of rubber rollers arranged at intervals along the axial direction of the rotating shaft. The outer circumferential surfaces of the plurality of rubber rollers are used for rolling contact with the outer circumferential sidewall of the pipe pile mold.

[0016] Furthermore, each of the buffer components includes a spring seat disposed on the lower end face of the lateral support, a telescopic rod structure, and a buffer spring sleeved on the outside of the telescopic rod structure. The top of the telescopic rod structure is connected to the spring seat, one end of the buffer spring abuts against the spring seat, and the lower end of the buffer component is connected to the mounting base.

[0017] Compared with the prior art, the vibratory compaction device for preparing concrete pipe piles according to this utility model has the following advantages:

[0018] 1. By incorporating multiple vibration actuators distributed axially along the pipe pile mold within the vibratory compaction assembly, and employing I-shaped vibration supports in conjunction with an elastic pad, the vibration force can achieve multi-point loading and a more uniform distribution of vibration energy at the bottom of the pipe pile mold. This improves the vibration coverage effect along the length of the large pipe pile mold. Multi-point vibration loading not only enhances the fluidity and redistribution of concrete at different axial positions within the mold but also more effectively eliminates air bubbles in the concrete, thereby improving the density and uniformity of various parts of the pipe pile cross-section. Simultaneously, the elastic pad's role in vibration coupling and buffering reduces local stress concentration and impact peaks, helping to extend the service life of the mold and related components, and reducing noise and vibration discomfort during equipment operation.

[0019] 2. By setting a lateral support assembly with an arc-shaped support surface and rolling support components on the side of the pipe pile mold, and arranging a buffer assembly with a buffer spring and telescopic structure below it, and supplemented by a limiting assembly set on the outer side, a multi-level support and limiting system is formed, so that the pipe pile mold can obtain stable and reliable lateral support and effective displacement restriction during vibration. The combination of the arc-shaped support surface and the rubber roller can not only conform to the outer contour of the pipe pile mold, but also reduce frictional resistance through rolling contact, which is conducive to keeping the mold stable during feeding, positioning and vibration. The elastic connection of the buffer assembly can absorb some vibration energy, reduce the impact of vibration directly transmitted to the foundation structure, and help improve the smoothness of the whole machine operation. The outer limiting assembly provides rigid limiting protection when the mold deviates abnormally, thereby effectively preventing the mold from dislodging or overturning under high-frequency vibration, improving the safety and consistency of the vibration process.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] This utility model embodiment, combining existing production processes for concrete pipe pile preparation, addresses the problems of single-point or few-point vibration in current concrete pipe pile molding, uneven distribution of vibration energy along the length and circumference of large pipe pile molds, which easily leads to local honeycomb, pitting, and insufficient density. It provides a vibration device for concrete pipe pile preparation. This device improves the vibration transmission path and vibration coverage while ensuring mold stability, thereby optimizing the molding quality of concrete within large pipe pile molds. It incorporates a multi-point vibration loading structure at the bottom of the pipe pile mold, lateral support components with buffering and rolling support functions on the sides of the mold, and limiting components on the outside of the mold to prevent dislocation during vibration.

[0032] In this embodiment, as shown in the accompanying drawings, a vibratory compaction device for preparing concrete pipe piles includes a vibratory compaction assembly 100 and two symmetrically arranged lateral support assemblies 200. The vibratory compaction assembly 100 is arranged between the two lateral support assemblies 200 and is used to support and vibrate the bottom of the concrete pipe pile mold placed thereon, so that the pipe pile mold receives a bottom-up vibration input under the action of the vibratory compaction assembly 100; the arrangement of the two lateral support assemblies 200 and the vibratory compaction assembly 100 forms a clamping relationship in the plane, so as to jointly provide lower support and lateral support to the pipe pile mold during the vibration process.

[0033] The vibratory compaction assembly 100 includes at least two vibratory actuators distributed along the axial direction of the pipe pile mold, a vibratory support 110, and an elastic pad 120 laid on the upper surface of the vibratory support 110. The vibratory support 110 extends axially along the pipe pile mold, and its cross-section is preferably I-shaped to improve its load-bearing capacity and bending stiffness under multi-point loading conditions, thus facilitating the maintenance of overall structural stability. The output ends of the multiple vibratory actuators are respectively connected to the bottom or side of the vibratory support 110 to transmit vibration force to the vibratory support 110 during operation, and then to the bottom of the pipe pile mold above it. The elastic pad 120, laid on the upper surface of the vibratory support 110, is preferably a rubber pad structure, providing elastic buffering and frictional fit between the pipe pile mold and the vibratory support 110, avoiding local stress concentration in the mold caused by rigid contact, and improving vibration coupling effect.

[0034] In practical implementation, the vibration actuator is selected as a vibratory cylinder 130, and two vibratory cylinders 130 are provided, symmetrically arranged front and back along the length of the vibratory support 110. This symmetrical arrangement ensures that the vibratory assembly 100 forms at least two vibration loading points in the axial direction of the pipe pile mold, providing relatively uniform vibration input within the length of the large pipe pile mold and reducing the problems of insufficient local amplitude or vibration dead zones caused by single-point vibration. The vibratory cylinders 130 can be fixed to the bottom of the vibratory support 110 by bolt or flange connection. The vibration frequency and amplitude can be adjusted according to the size of the pipe pile mold and the concrete mix ratio to meet the production needs of pipe piles of different specifications.

[0035] Each lateral support assembly 200 includes a lateral support seat 210, a rolling support member 230 disposed on the upper end face of the lateral support seat 210, and a plurality of buffer assemblies 240 disposed on the lower end face of the lateral support seat 210 for elastic connection with the mounting foundation. The lateral support seat 210 extends axially along the pipe pile mold, and its upper end face is an arc-shaped support surface facing the vibrating assembly 100. The arc-shaped support surface matches the outer arc-shaped contour of the pipe pile mold to be supported, so as to provide stable lateral support when the pipe pile mold is placed. An installation groove 220 extending axially along the pipe pile mold is provided in the arc-shaped support surface. The installation groove 220 is through or partially formed inside the upper end face of the lateral support seat 210 to accommodate the rolling support member 230, so that the rolling support member 230 is reliably installed on the lateral support seat 210 and remains rotatable.

[0036] The rolling support component 230 includes a rotating shaft rotatably disposed within the mounting groove 220 and multiple rubber rollers spaced apart along the axial direction of the rotating shaft. The outer circumferential surfaces of the multiple rubber rollers are used for rolling contact with the outer circumferential sidewall of the pipe pile mold. The rubber rollers can adopt an integral rubber-coated structure or a rubber-coated metal wheel core structure to balance support strength and surface friction performance. When the pipe pile mold is placed between the vibrating assembly 100 and the lateral support assembly 200, the rubber rollers can achieve rolling support for the pipe pile mold through their own rotation, which reduces the sliding friction between the mold and the support structure, and also buffers the impact force during vibration transmission to a certain extent, avoiding damage to the outer wall of the mold.

[0037] To achieve an elastic connection between the lateral support 210 and the mounting foundation, each buffer assembly 240 includes a spring seat 250 disposed on the lower end face of the lateral support 210, a telescopic rod structure connected to the spring seat 250, and a buffer spring sleeved on the outside of the telescopic rod structure. The spring seat 250 is fixedly arranged at the bottom of the lateral support 210, the top of the telescopic rod structure is connected to the spring seat 250, one end of the buffer spring abuts against the spring seat 250, and the lower end of the buffer assembly 240 is connected to the mounting foundation, for example, by mounting it on the equipment foundation or production line platform via a base plate or embedded part. The buffer assembly 240 allows the lateral support 210 to undergo a small-amplitude elastic displacement relative to the mounting foundation during vibration, absorbing some of the vibration energy while maintaining the overall support stability of the pipe pile mold, thereby reducing the vibration impact transmitted to the foundation.

[0038] To prevent excessive radial displacement or displacement of the pipe pile mold during high-frequency vibration, the vibration device in this embodiment also includes two symmetrically arranged limiting components 300. Each limiting component 300 is arranged outside the corresponding lateral support component 200 and includes a limiting support 310 and a limiting rod 320 connected to the limiting support 310. The limiting support 310 is fixed to the foundation or equipment frame by welding or bolting. The limiting rod 320 is arranged along the axial direction of the pipe pile mold and is located outside the outer circle of the pipe pile mold. An appropriate gap is reserved between the limiting rod 320 and the outer circle of the pipe pile mold so that it does not directly contact the mold under normal support. When the pipe pile mold shows a large radial displacement tendency under vibration, the limiting rod 320 can form a limiting block on its outer circle side, thereby effectively limiting the radial displacement of the pipe pile mold during vibration and preventing the mold from leaving the support area of ​​the vibration component 100 and the lateral support component 200.

[0039] How this example works

[0040] Step 1: The vibratory tamping assembly 100 and two lateral support assemblies 200 are pre-installed on the equipment foundation of the production line, and the lateral support assemblies 200 are reliably connected to the installation foundation through the buffer assembly 240. At the same time, the height of the vibratory support seat 110 and the spacing between the two lateral support assemblies 200 are adjusted to match the diameter and length of the pipe pile mold to be processed.

[0041] Step 2: The pre-assembled concrete pipe pile mold is hoisted to the vibrating device using a lifting device, so that the bottom of the pipe pile mold rests on the elastic pad 120 of the vibrating component 100. At the same time, the outer circular side wall of the pipe pile mold contacts the rolling support 230 on the two lateral support components 200 to form a stable support. The position of the limiting component 300 is adjusted so that the limiting rod 320 maintains an appropriate limiting gap relative to the outer circle of the pipe pile mold.

[0042] Step 3: After the concrete pouring is completed and the pipe pile mold is sealed, the vibrating cylinder 130 is started, so that multiple vibrating cylinders 130 work at the set frequency and amplitude. The bottom of the pipe pile mold is subjected to multi-point vibration loading through the vibrating support seat 110 and the elastic pad 120. At the same time, with the cooperation of the lateral support component 200 and the buffer component 240, the posture stability and lateral support elasticity of the pipe pile mold are ensured during the vibration process. At this time, the limiting component 300 plays a protective role against abnormal displacement trends.

[0043] Step four: After the predetermined vibration time is reached or the air bubbles inside the concrete are eliminated and the density meets the process requirements, stop the operation of the vibrating cylinder 130, release the vibration state, and after the concrete has completed its initial setting, remove the pipe pile mold from the vibrating device using lifting equipment to complete this round of concrete pipe pile preparation vibration process.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
