Description

Technical Field

[0001] This utility model relates to the field of mixing pile construction technology, and in particular to a mud splash prevention device for mixing piles. Background Technology

[0002] During the construction of triple-axis mixing piles, the rotation of the drill rod generates a large amount of mud. If not effectively contained, the splashing mud will not only pollute the construction site environment and increase cleanup costs, but may also affect the safety and health of construction workers and even damage surrounding equipment. Therefore, mud-blocking technology has become a key element in ensuring the smooth progress of construction.

[0003] Currently, the most common method for addressing mud splashing in triple-axis mixing pile construction is the use of fixed mudguards. These mudguards are typically made of steel or wood plates and are installed around the drill rod through welding or bolting. They form a rigid physical barrier to prevent mud from spreading. However, this existing technology has several shortcomings in practical use. First, the fixed position of the mudguard cannot be dynamically adjusted with the raising and lowering of the drill rod, making it difficult to precisely match the drill rod's working trajectory. This causes mud to easily overflow from the gap between the mudguard and the drill rod, significantly reducing the mud-blocking effect. Furthermore, the friction between the two causes wear and tear on the device, shortening its service life. Second, traditional mud bottom collection devices often use an open structure, making it easy for mud to splash secondary when falling into the collection device, hindering effective mud recovery. Third, the weight of materials such as steel mudguards increases the load on construction equipment, affecting its operating efficiency. Moreover, they are inconvenient to assemble and disassemble during construction, consuming significant manpower and time costs, and hindering rapid construction progress and flexible adjustments. Utility Model Content

[0004] The technical problems to be solved by this utility model are: poor adaptability, low mud recovery efficiency, and heavy materials.

[0005] To solve the above-mentioned technical problems, this utility model provides a mud splash prevention device for mixing piles, including a shielding component and a base;

[0006] The shielding assembly includes multiple shielding units, which are rotatably connected to each other. The shielding units at one end of the multiple shielding units are used to connect to the mixing pile drill rod, and the shielding units at the other end of the multiple shielding units are connected to the base.

[0007] Preferably, the shielding unit includes a first shielding plate and a second shielding plate, with the first shielding plate rotatably connected to the second shielding plate.

[0008] Preferably, the shielding unit includes a connecting assembly, which includes a first connecting block, a second connecting block, and a rotating shaft. One end of the first connecting block is fixedly connected to the first shielding plate, and the other end of the first connecting block is rotatably connected to the rotating shaft. One end of the second connecting block is fixedly connected to the second shielding plate, and the other end of the second connecting block is rotatably connected to the rotating shaft.

[0009] Preferably, the number of connecting components is two, with two first connecting blocks spaced apart on the first shield and two second connecting blocks spaced apart on the second shield.

[0010] Preferably, the shield is made of aluminum alloy.

[0011] Preferably, the length of the first and second shielding plates is 2.2m to 2.8m, the width of the first and second shielding plates is 0.4m to 0.8m, and the thickness of the first and second shielding plates is 0.4cm to 0.8cm.

[0012] Preferably, the mud splash prevention device for mixing piles further includes a support frame, which includes multiple spaced support rods. One end of each support rod is curved, and each support rod is fixedly connected to the base. Multiple shielding units located at their other ends are connected to the base by connecting to the support rods.

[0013] Preferably, the mud splash prevention device for the mixing pile further includes an installation assembly, which includes a sliding member and a connecting plate. The sliding member is slidably connected to the mixing pile drill rod, one side of the connecting plate is fixedly connected to the sliding member, and the other side of the connecting plate is fixedly connected to a shielding unit for connecting to the mixing pile drill rod.

[0014] Preferably, the installation assembly further includes a connecting rod, and there are multiple sliding elements, each of which is slidably connected to a corresponding mixing pile drill rod. The multiple sliding elements are spaced apart and fixedly connected to the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the mud splash prevention device for mixing piles according to this utility model embodiment are as follows:

[0016] (1) In this embodiment of the invention, multiple shielding units are rotatably connected, and both ends are connected to the mixing pile drill rod and the base, respectively, so that the shielding components can closely fit the lifting trajectory of the drill rod. During the lifting and lowering of the drill rod, the shielding units can flexibly rotate and adjust their angles to always maintain effective shielding of the mud. Compared with fixed mudguards, this can significantly reduce the leakage of mud from the gaps, significantly improve the mud-blocking efficiency, and effectively prevent mud from polluting the construction site environment.

[0017] (2) The modular structure with rotating connection makes the shielding component highly adaptable, allowing for flexible adjustment and installation according to different specifications and construction conditions of the mixing pile drill rods. Whether it is a change in drill rod diameter or a difference in the terrain of the construction site, the device can achieve good adaptation by adjusting the combination and angle of the shielding units, effectively solving the problem of poor adaptability in the existing technology and meeting diverse construction needs.

[0018] (3) Compared to a bulky single steel baffle, this device uses a design of multiple individual units rotating and connected, making the overall structure lighter and the connection method between the components easy to disassemble and assemble. During the equipment installation before construction and the equipment transfer after construction, it can significantly save manpower and time costs, effectively improve construction efficiency, and facilitate rapid construction progress and flexible adjustments.

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 As shown, a preferred embodiment of the present invention provides a mud splash prevention device for mixing piles, which includes a shielding component 1 and a base 2.

[0035] The shielding assembly 1 includes multiple shielding units 11, which are rotatably connected to each other. The shielding unit 11 located at one end of the multiple shielding units 11 is used to connect to the mixing pile drill rod 200, and the shielding unit 11 located at the other end of the multiple shielding units 11 is connected to the base 2.

[0036] Based on the above solution, multiple shielding units 11 in this embodiment are rotatably connected, with their ends connected to the mixing pile drill rod 200 and the base 2, respectively, so that the shielding component 1 can closely conform to the lifting trajectory of the drill rod. During the lifting and lowering of the drill rod, the shielding unit 11 can flexibly rotate and adjust its angle to always maintain effective shielding of the mud. Compared with fixed mudguards, this significantly reduces the leakage of mud from gaps, significantly improves mud-blocking efficiency, and effectively avoids mud pollution of the construction site environment. The modular structure of the rotatable connection gives the shielding component 1 strong adaptability, allowing for flexible adjustment and installation according to different specifications and construction conditions of the mixing pile drill rod 200. Whether it is a change in drill rod diameter or a difference in construction site terrain, this device can achieve good adaptation by adjusting the combination and angle of the shielding units 11, effectively solving the problem of poor adaptability in the prior art and meeting diverse construction needs. The device adopts a design of multiple units rotatably connected, making the overall structure lighter, and the connection method between each component is easy to disassemble and assemble. During the equipment installation before construction and the equipment transfer after construction, it can significantly save manpower and time costs, effectively improve construction efficiency, and facilitate rapid construction progress and flexible adjustments.

[0037] Furthermore, the shielding unit 11 includes a first shielding plate 111 and a second shielding plate 112, with the first shielding plate 111 rotatably connected to the second shielding plate 112.

[0038] Multiple shielding units 11 are rotatably connected, with each end connected to the mixing pile drill rod 200 and the base 2, respectively, allowing the shielding assembly 1 to closely conform to the lifting trajectory of the drill rod. During the lifting and lowering of the drill rod, the shielding units 11 can flexibly rotate and adjust their angles, always maintaining effective shielding of the mud, significantly reducing mud overflow from gaps, significantly improving mud-blocking efficiency, and effectively preventing mud pollution of the construction site environment. The modular structure with rotatable connections is adaptable, allowing for flexible adjustment and installation according to different specifications and construction conditions of the mixing pile drill rod 200. Whether it is a change in drill rod diameter or a difference in construction site terrain, the device can achieve good adaptation by adjusting the combination and angle of the shielding units 11, meeting diverse construction needs. Through dynamic synchronous adjustment, hard collisions between mechanical parts are reduced, extending the service life of the entire mud splash prevention device, reducing equipment maintenance costs and downtime replacement time, and ensuring the continuity of construction. The device adopts a design of multiple units rotatably connected, making the overall structure lighter, and the connection method between each component facilitates disassembly and assembly. During the equipment installation before construction and the equipment transfer after construction, it can significantly save manpower and time costs, effectively improve construction efficiency, and facilitate rapid construction progress and flexible adjustments.

[0039] Furthermore, the shielding unit 11 includes a connecting assembly 113, which includes a first connecting block 1131, a second connecting block 1132, and a rotating shaft 1133. One end of the first connecting block 1131 is fixedly connected to the first shielding plate 111, and the other end of the first connecting block 1131 is rotatably connected to the rotating shaft 1133. One end of the second connecting block 1132 is fixedly connected to the second shielding plate 112, and the other end of the second connecting block 1132 is rotatably connected to the rotating shaft 1133.

[0040] The first connecting block 1131 and the second connecting block 1132 are rotatably connected to the rotating shaft 1133, allowing the first shielding plate 111 and the second shielding plate 112 to rotate relative to each other around the rotating shaft 1133, forming an adjustable shielding angle. The shielding range can be dynamically adjusted according to the actual direction of mud splashing during construction based on the operating angle of the mixing pile machinery, precisely covering the splash area and improving splash prevention efficiency. The first shielding plate 111 and the second shielding plate 112 are connected by the rotating shaft 1133, allowing them to be folded away when not in use, reducing the device's size, facilitating transportation and storage, and lowering transportation costs. During installation, the position of the shielding plates can be adjusted by rotating the connecting blocks, allowing for quick positioning without complex tools and shortening pre-construction preparation time.

[0041] Furthermore, there are two connecting components 113, with two first connecting blocks 1131 spaced apart on the first shielding plate 111 and two second connecting blocks 1132 spaced apart on the second shielding plate 112.

[0042] By setting two spaced connecting blocks on each of the first baffle plate 111 and the second baffle plate 112, a symmetrical double-support structure is formed, which significantly improves the overall stability compared to a single connecting component 113. When mud splashes onto the baffle plate, the two connecting components 113 can evenly distribute the impact force, avoiding the baffle plate tilting, deformation, or breakage of the connecting component 113 caused by unilateral force, which is especially suitable for high-pressure splashing scenarios. The symmetrically distributed connecting blocks can balance the torque on both sides of the baffle plate, preventing eccentric wear of the rotating shaft 1133 due to uneven force, and extending the service life of the device.

[0043] Furthermore, the shield is made of aluminum alloy.

[0044] Aluminum alloy has a density approximately one-third that of steel, making it lighter for the same volume. Reducing the overall weight of the splash shield facilitates handling, installation, and dismantling by construction workers, making it particularly suitable for construction sites requiring frequent equipment movement. It also reduces the load-bearing requirements on mounting brackets or mechanical support structures, preventing increased equipment load due to excessive shield weight and improving mechanical stability. A dense alumina passivation film naturally forms on the aluminum alloy surface, effectively resisting corrosion from moisture, acids, and alkalis in the mud. This avoids problems such as reduced shield structural strength and coating peeling caused by rust, extending the device's lifespan and reducing replacement frequency. Compared to steel, it eliminates the need for additional rust-preventive paint or anti-corrosion treatment, reducing both initial manufacturing and subsequent maintenance costs.

[0045] Furthermore, the length of the first shielding plate 111 and the second shielding plate 112 is 2.2m to 2.8m, the width of the first shielding plate 111 and the second shielding plate 112 is 0.4m to 0.8m, and the thickness of the first shielding plate 111 and the second shielding plate 112 is 0.4cm to 0.8cm.

[0046] In this embodiment, a length of 2.5m is preferred to accommodate the common pile diameter range of mixing piles and the size of construction equipment. This allows for compatibility with small piles or narrow construction spaces, avoiding operational limitations due to excessively long shielding plates. It also effectively covers the mud splash range during pile construction, reducing lateral splash blind spots. The installation height of the shielding plate can be adjusted according to the pile depth. During drilling, as the mud splash range changes with depth, a longer shielding plate can cover a larger vertical area, ensuring a consistent splash-proof effect throughout the process. In this embodiment, a width of 0.5m is preferred to reduce material consumption and equipment weight, while also blocking upward-splashing mud to prevent contamination of the equipment top or surrounding facilities. In this embodiment, a thickness of 0.5m is preferred, as it is suitable for conventional mud splash pressure, and the aluminum alloy material maintains sufficient rigidity at this thickness while being lightweight for easy handling; it also prevents deformation or breakage of the shielding plate.

[0047] Furthermore, the mud splash prevention device for mixing piles also includes a support frame 3, which includes multiple spaced support rods 31. One end of each support rod 31 is curved, and each support rod 31 is fixedly connected to the base 2. Multiple shielding units 11 located at their other ends are connected to the support rods 31 to the base 2.

[0048] Multiple support rods 31 with one end curved together form a storage opening, which can store the shielding component 1 after it is folded when the drill rod moves down.

[0049] Furthermore, the mud splash prevention device for the mixing pile also includes an installation assembly 114, which includes a sliding member 1141 and a connecting plate 1142. The sliding member 1141 is slidably connected to the mixing pile drill rod 200, one side of the connecting plate 1142 is fixedly connected to the sliding member 1141, and one side of the connecting plate 1142 is fixedly connected to the shielding unit 11 for connecting to the mixing pile drill rod 200.

[0050] The sliding element can slide up and down along the drilling rod 200 of the mixing pile, allowing the shielding unit 11 to dynamically adjust its height as the drilling rod 200 drills or is lifted, covering mud splash points at different depths. The fixed connection between the connecting plate and the sliding element allows the shielding unit 11 to adjust its tilt angle synchronously during sliding, adapting to changes in the verticality of the drilling rod 200 or deviations in the direction of mud injection, thus improving the shielding fit.

[0051] Furthermore, the installation assembly 114 also includes a connecting rod 1143 and multiple sliding members 1141. The multiple sliding members 1141 are slidably connected to the corresponding mixing pile drill rod 200, and the multiple sliding members 1141 are spaced apart and fixedly connected to the connecting rod 1143.

[0052] When mud impacts the shielding plate, multiple sliding parts 1141 work together via connecting rod 1143 to prevent the sliding parts 1141 from detaching from the drill pipe 200 or the shielding plate from tilting due to single-point overload. The rigid support of connecting rod 1143 suppresses the vibration amplitude of the shielding plate, reducing bolt loosening or component fatigue damage caused by long-term vibration. During the drilling process of the drill pipe 200, the mud splash point changes with depth, and connecting rod 1143, together with multiple sliding parts, moves upward synchronously, ensuring the shielding plate always covers the splash area.

[0053] In summary, this utility model embodiment provides a mud splash prevention device for mixing piles. Multiple shielding units 11 are rotatably connected, with both ends connected to the mixing pile drill rod 200 and the base 2, respectively. This allows the shielding component 1 to closely conform to the lifting trajectory of the drill rod. During the lifting and lowering of the drill rod, the shielding unit 11 can flexibly rotate and adjust its angle, always maintaining effective shielding against mud. Compared to fixed mudguards, this significantly reduces mud overflow from gaps, significantly improves mud-blocking efficiency, and effectively prevents mud pollution of the construction site environment. The modular structure with rotatable connections gives the shielding component 1 strong adaptability, allowing for flexible adjustment and installation according to different specifications and construction conditions of the mixing pile drill rod 200. Whether it's a change in drill rod diameter or differences in construction site terrain, this device can achieve good adaptation by adjusting the combination and angle of the shielding units 11, effectively solving the problem of poor adaptability in existing technologies and meeting diverse construction needs. The device adopts a design with multiple units rotatably connected, making the overall structure lighter, and the connection method between the components facilitates disassembly and assembly. During the equipment installation before construction and the equipment transfer after construction, it can significantly save manpower and time costs, effectively improve construction efficiency, and facilitate rapid construction progress and flexible adjustments.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
