Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a mud splash baffle applied to the construction of triaxial mixing piles. Background Technology

[0002] Triaxial mixing piles are widely used in foundation engineering construction. When the equipment is mixing, a large amount of mud splashes will inevitably be generated as the drill bit rotates at high speed and cement slurry is injected. In order to prevent mud from polluting the surrounding environment and to ensure the safety of on-site construction personnel, anti-splash baffles are usually installed on the outside of the mixing equipment for shielding.

[0003] Most current splash guards use a rigid structure with a fixed height, which cannot be flexibly raised and lowered according to changes in drilling depth or the needs of different construction stages, resulting in limited protection range and sometimes even interfering with the normal operation of machinery. At the same time, existing closed guards make it inconvenient for construction personnel to observe the internal pile mixing status in real time, and opening unprotected openings directly will cause mud to overflow. In daily construction, there is a lack of a structure that balances the convenience of observation and the safety of sealing. In addition, the ground surface of the construction site is often uneven and undulating. When the bottom edge of the traditional straight guard comes into contact with the uneven ground, there will be obvious gaps. During equipment movement or operation, splashed mud will seep out from the gaps at the bottom, which greatly reduces the overall protection effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mud splash guard for use in the construction of triaxial mixing piles. It solves the problems of existing splash guards having a fixed and unadjustable height, lacking a safe and reliable internal observation structure, and having gaps at the bottom that lead to slurry leakage due to uneven construction sites.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mud splash guard for use in triaxial mixing pile construction, comprising two mounting plates, a hydraulic rod fixedly connected to the top of each mounting plate, the telescopic end of the hydraulic rod penetrating the mounting plate and fixedly connected to a splash guard, two splash guards, two folding plates disposed between the two splash guards, the folding plates and the splash guards being interlocked, a limiting shaft penetrating between the splash guards and the folding plates, an observation port being provided in the middle of one of the splash guards, two side doors being rotatably connected to the edge of the observation port on the splash guard, and a lifting adjustment mechanism being provided on the outer side of the splash guard.

[0006] Preferably, the lifting and adjusting mechanism includes two slide rails, which are respectively fixedly connected to the top of the splash guard. Slider blocks are slidably connected to both sides of the slide rails. Rotating bars are rotatably connected to the outer side of the sliders. T-shaped blocks are rotatably connected to the other ends of the two rotating bars. The T-shaped blocks are fixedly connected to the outer side of the mounting plate. Mounting limiting holes are provided on both sides of the outer side of the mounting plate. Engaging grooves are provided on adjacent sides of the two mounting plates. Mounting bars are fixedly connected to the outer side of the splash guard and the folding plate. Multiple V-shaped slurry baffles are fixedly connected to the outer side of the mounting bars.

[0007] Preferably, a self-locking mechanism is provided on the outer side of the side door. The self-locking mechanism includes two semi-locking pins, which are respectively fixedly connected to the adjacent outer sides of the two side doors. A semi-arc rail is fixedly connected to the outer side of the side door. An arc-shaped locking block is slidably connected to the outer side of the semi-arc rail. A retraction spring is fixedly connected to the outer side of the arc-shaped locking block. A limiting post is fixedly connected to the outer side of the side door. The end of the retraction spring away from the arc-shaped locking block is rotatably connected to the outer side of the limiting post.

[0008] Preferably, the bottom end of the splash guard is provided with an adaptive telescopic mechanism, which includes two grooves. The two grooves are respectively opened at the bottom end of the splash guard. A telescopic chain baffle is slidably connected to the inner side of the groove. Both ends of the telescopic chain baffle are fixedly connected to a fixing plate. The outer sides of the two fixing plates are rotatably connected to casters.

[0009] Preferably, the connection point between the hydraulic rod and the splash plate is located at the top center of the splash plate, and both ends of the limiting shaft extend to the outside of the splash plate.

[0010] Preferably, a rotating shaft is provided at the rotating connection point between the rotating bar and the slider and the T-shaped block, and the mounting bar is arranged along the length direction of the splash guard and the folding plate.

[0011] Preferably, the plurality of V-shaped baffles are arranged at equal intervals along the length of the mounting strip, and the opening of the engaging groove faces the adjacent direction of the two mounting plates.

[0012] Preferably, the arc-shaped opening of the semi-arc track faces the outside of the side door, the arc-shaped locking block is adapted to the semi-locking post, and the adjacent ends of the two side doors fit together.

[0013] Preferably, the limiting post and the semi-circular rail are located on different sides of the side door, and the arc-shaped locking block engages with the semi-locking post when the retraction spring is in its natural state.

[0014] Preferably, the groove is formed along the width direction of the splash guard, the length of the telescopic chain baffle is adapted to the width of the splash guard, and the wheel surface of the universal wheel extends to the outside of the fixed plate.

[0015] This invention provides a mud splash shield for use in triaxial mixing pile construction. It has the following beneficial effects: 1. This invention, by setting up a lifting and adjusting mechanism, uses a hydraulic rod to drive the splash guard and folding plate to rise and fall. At the same time, with the linkage of the slide rail, slider, rotating bar and T-block, the splash guard maintains the stability of the overall structure during the lifting and falling process. This design can flexibly adjust the protection height of the baffle according to different stages of the construction of the three-axis mixing pile, effectively improving the applicability of the anti-splash device.

[0016] 2. The present invention has an observation port and a side door set on the splash plate, and is used in conjunction with a self-locking mechanism. Construction personnel can quickly open the side door to check the internal construction conditions by sliding the arc-shaped locking block to disengage it from the half-locking column. The structure is easy to operate and can reliably lock the side door when observation is not required, preventing mud from accidentally overflowing or splashing from the observation port during the construction process.

[0017] 3. The splash guard of the present invention is provided with an adaptive telescopic mechanism at the bottom. When it passes through the universal wheel moving device, if it encounters uneven ground, the telescopic chain baffle can passively slide up and down in the grooves at both ends. This design enables the bottom of the device to adapt to the terrain undulations of the construction site, avoid the problem of bottom grout leakage caused by uneven ground, and ensure the tightness of protection.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 This invention provides a mud splash guard for use in the construction of triaxial mixing piles, comprising two mounting plates 1, a hydraulic rod 5 fixedly connected to the top of the mounting plate 1, the telescopic end of the hydraulic rod 5 passing through the mounting plate 1 and fixedly connected to a splash guard 6, the number of splash guards 6 being two, two folding plates 7 being provided between the two splash guards 6, the folding plates 7 and the splash guards 6 being interlocked, a limiting shaft 8 being provided through the splash guards 6 and the folding plates 7, an observation port 9 being provided in the middle of one of the splash guards 6, two side doors 10 being rotatably connected at the edge of the observation port 9 of the splash guard 6, and a lifting adjustment mechanism 2 being provided on the outer side of the splash guard 6; The lifting and adjusting mechanism 2 includes two slide rails 26, which are fixedly connected to the top of the splash plate 6. Slider 21 is slidably connected to both sides of the slide rails 26. Rotating strips 22 are rotatably connected to the outer side of the sliders 21. T-shaped blocks 23 are rotatably connected to the other ends of the two rotating strips 22. T-shaped blocks 23 are fixedly connected to the outer side of the mounting plate 1. Mounting limiting holes 24 are opened on both sides of the outer side of the mounting plate 1. Engaging grooves 25 are opened on the adjacent side of the two mounting plates 1. Mounting strips 27 are fixedly connected to the outer side of the splash plate 6 and the folding plate 7. Multiple V-shaped baffles 28 are fixedly connected to the outer side of the mounting strips 27. The hydraulic rod 5 is connected to the splash plate 6 at the top center of the splash plate 6, and the two ends of the limiting shaft 8 extend to the outside of the splash plate 6; the rotating bar 22 is provided with a rotating shaft at the rotating connection with the slider 21 and the T-block 23; the mounting bar 27 is arranged along the length direction of the splash plate 6 and the folding plate 7; multiple V-shaped baffle plates 28 are arranged at equal intervals along the length direction of the mounting bar 27, and the slots of the locking grooves 25 face the adjacent directions of the two mounting plates 1; Specifically, two mounting plates 1 are placed on the outside of the mixing head cover. Since there are mounting posts on the outside of the mixing head cover, the mounting limiting holes 24 on the top of the mounting plate 1 are passed through the mounting posts on the outside of the mixing head cover. The mounting plates 1 are then installed on the outside of the mixing head cover using nuts. Subsequently, folding plates 7 are inserted into both ends of the two splash plates 6 respectively. Then, the limiting shaft 8 is passed through the splash plates 6 and folding plates 7 from the top in sequence, thereby connecting the folding plates 7 and splash plates 6 together, thus completing the installation of the anti-splash baffle. Before the construction of the triaxial mixing pile is carried out, the hydraulic rod 5 is activated to push the splash plates 6 downwards, and the folding plates 7 are moved forward together. As the splash plate 6 moves downward, the distance between it and the T-shaped block 23 gradually increases. Since the position of the T-shaped block 23 is fixed, the rotation angle of the rotating bar 22 changes accordingly, which in turn drives the sliders 21 on both sides of the top slide rail 26 of the splash plate 6 to slide along the slide rail 26, providing guidance and limiting for the splash plate 6 as it moves downward, thus keeping it stable. At the same time, mounting strips 27 are fixedly connected to the splash plate 6 and the folding plate 7 in sequence, and a V-shaped baffle plate 28 is fixedly connected below the mounting strips 27. The inclined surface of the V-shaped baffle plate 28 can guide the mud to slide downward, preventing the splashed mud from sticking to the splash plate 6 and the folding plate 7.

[0022] See appendix Figure 5 and attached Figure 6 A self-locking mechanism 3 is provided on the outer side of the side door 10. The self-locking mechanism 3 includes two half-locking pins 31, which are fixedly connected to the adjacent outer sides of the two side doors 10 respectively. A semi-arc rail 32 is fixedly connected to the outer side of the side door 10. An arc-shaped locking block 33 is slidably connected to the outer side of the semi-arc rail 32. A retraction spring 34 is fixedly connected to the outer side of the arc-shaped locking block 33. A limiting post 35 is fixedly connected to the outer side of the side door 10. The end of the retraction spring 34 away from the arc-shaped locking block 33 is rotatably connected to the outer side of the limiting post 35. The arc-shaped opening of the semi-arc track 32 faces the outside of the side door 10, the arc-shaped locking block 33 is adapted to the semi-locking post 31, and the adjacent ends of the two side doors 10 fit together; the limiting post 35 and the semi-arc track 32 are located on different sides of the side door 10 respectively, and the arc-shaped locking block 33 and the semi-locking post 31 are engaged when the retraction spring 34 is in its natural state. Specifically, when it is necessary to observe the construction of the three-axis mixing pile, the arc-shaped locking block 33 is manually rotated. At this time, the two arc-shaped locking blocks 33 will slide above the semi-arc rail 32 and stretch the spring 34 until the two arc-shaped locking blocks 33 are in a vertical state, so that the arc-shaped locking blocks 33 disengage from the semi-locking column 31, thereby releasing the arc-shaped locking blocks 33 from the semi-locking column 31. Then, the side door 10 is pulled outward to open the locked side door 10. During this process, the V-shaped baffle plate 28 can be used as a force-bearing handle to pull. After opening the side door 10, the construction of the three-axis mixing pile can be inspected or spot-checked.

[0023] See appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 7 The bottom end of the splash guard 6 is provided with an adaptive telescopic mechanism 4. The adaptive telescopic mechanism 4 includes two grooves 41. The two grooves 41 are respectively opened at the bottom end of the corresponding splash guard 6. The inner side of the groove 41 is slidably connected to the telescopic chain baffle 42. Both ends of the telescopic chain baffle 42 are fixedly connected to the fixing plates 43. The outer sides of the two fixing plates 43 are rotatably connected to the universal wheels 44. The groove 41 is opened along the width direction of the splash plate 6, the length of the telescopic chain baffle 42 is adapted to the width of the splash plate 6, and the wheel surface of the universal wheel 44 extends to the outside of the fixed plate 43. Specifically, after the lifting adjustment mechanism 2 completes the adjustment, the caster wheel 44 is in contact with the ground. When moving, the caster wheel 44 will roll on the ground. When the ground is uneven, the telescopic chain baffle 42 will automatically slide up and down due to the pressure of the ground protrusion or its own weight, so as to adapt to the height difference of the ground. The telescopic chain baffle 42 will slide in the groove 41 to maintain the continuity of the bottom protection structure.

[0024] Working principle: First, align and fix the mounting limiting hole 24 of the mounting plate 1 to the outside of the stirring head cover. Insert the folding plate 7 between the two splash plates 6. Then, use the limiting shaft 8 to pass through the splash plate 6 and the folding plate 7 to complete the connection of the baffle assembly. When adjusting the height, the hydraulic rod 5 pushes the splash plate 6 and the folding plate 7 to move downwards synchronously. During the downward movement, because the position of the mounting plate 1 is fixed, the increased distance between the baffle and the mounting plate 1 causes the angle of the rotating bar 22 to change, thereby driving the slider 2 in the top slide rail 26 of the splash plate 6. 1. Sliding mechanism: In addition, the mounting strip 27 and V-shaped baffle 28 fixed on the outside of the baffle move synchronously with the overall structure. This mechanism can adjust the working height of the anti-splash baffle according to actual needs. The linkage mechanism between the slide rail 26 and the slider 21 improves the structural stability of the baffle during lifting and lowering, and prevents the baffle from tilting and getting stuck during movement. The V-shaped baffle 28 on the outside can use its inclined surface to change the splash trajectory of the mud, guide the mud to slide down, reduce the adhesion and accumulation of mud on the surface of the baffle, and facilitate subsequent cleaning. Furthermore, through the self-locking mechanism 3, when it is necessary to check the internal working status during construction, the operator manually moves the arc-shaped locking block 33, causing the arc-shaped locking block 33 to stretch and contract the spring 34 and slide along the semi-arc rail 32, disengaging from the semi-locking post 31 and releasing the locked state. Then, the side door 10 is opened to expose the observation port 9. After the inspection is completed, the side door 10 is closed. Under the action of the reset elastic force of the contraction spring 34, the arc-shaped locking block 33 automatically resets and re-locks onto the semi-locking post 31, completing the locking of the side door 10. By utilizing the spring reset force and the mechanical cooperation of the sliding rail 26 locking block, the side door 10 is quickly opened and closed and automatically reset and locked. The fastening parts are simplified, and it can resist the impact force generated by the splashing of mud inside, preventing the side door 10 from being opened accidentally. Meanwhile, through the adaptive telescopic mechanism 4, after the hydraulic rod 5 completes the overall height setting of the baffle, the universal wheel 44 at the bottom touches the ground and bears the force. During the overall movement of the device, the universal wheel 44 rolls along the ground. When there is an unevenness in the ground, the telescopic chain baffle 42 is squeezed by the ground or affected by gravity, and slides up and down relative to each other in the groove 41 to compensate for the height difference of the ground. This allows the bottom of the baffle to conform to the ground contour in real time, sealing the bottom gap caused by the terrain undulation and blocking the path of mud leakage. At the same time, the universal wheel 44 at the bottom provides rolling support for the horizontal movement of the device, reducing the frictional resistance of the equipment's translation.
