Description

Technical Field

[0001] This invention belongs to the field of mud pumping technology, specifically an adjustable height mud pumping device. Background Technology

[0002] Mud pits are critical circulation facilities in the construction of foundation engineering projects such as diaphragm walls and cast-in-place piles. They are mainly used for storing, recovering, and purifying the mud used for wall protection. As the core of the mud circulation system, the level and cleanliness of the mud inside the mud pit directly affect the stability of the trench walls, the quality of borehole formation, and the construction cost. Therefore, efficient and stable pumping and circulation of the mud in the mud pit is fundamental to ensuring the smooth progress of the project.

[0003] Currently, submersible pumps and other stationary equipment are commonly used for mud pumping during construction. Their basic structure includes a pump body, motor, and outlet pipe. During operation, the pump body is submerged to the bottom of the mud pit, and the mud is pumped out using electric power. While this equipment is simple in structure, its pumping height is fixed during installation. During construction, especially in the concrete pouring stage, mud overflows due to displacement, causing the liquid level to rise. Conversely, during the cleaning stage, the liquid level drops rapidly. To accommodate these frequent level fluctuations, operators must frequently lift the pump out of the pit, readjust its submersion depth, and then reinstall it. A single adjustment can take several hours. This is not only labor-intensive and inefficient, but also poses safety hazards during the adjustment process.

[0004] In practical applications, the aforementioned traditional fixed pumping equipment has poor adaptability and low efficiency. It cannot automatically adapt to the drastic fluctuations in the mud tank level, and manual adjustment is time-consuming and labor-intensive, which seriously affects construction efficiency. At the same time, the fixed depth can easily lead to incomplete pumping or cause equipment overload, wear, or even burnout due to pumping high-concentration slurry from too deep a burial depth.

[0005] Therefore, the present invention provides an adjustable height mud pumping device. Summary of the Invention

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 and Figure 8 As shown in the embodiment of the present invention, an adjustable height mud pumping device includes two sets of inclined support rods 1; each set of inclined support rods 1 is arranged in a figure-eight shape; an installation ring 2 is fixedly connected to the top of the inclined support rod 1; a crossbar 3 is provided on the inner ring between the two sets of installation rings 2; a hanging lug 4 is fixedly connected to the outer ring of the middle part of the crossbar 3; a hand chain hoist 5 is hung on the hanging lug 4; and a mud pump 6 is hung on the bottom of the hook of the hand chain hoist 5. Specifically, the mounting rings 2 at the top of each pair of inclined support rods 1 are coaxially aligned. The two ends of the crossbar 3 pass through the mounting rings 2 on both sides. The outer ring of the mounting ring 2 has a threaded hole, and a screw is installed inside the threaded hole. The screw presses against the outer wall of the crossbar 3, fixing and locking the mounting ring 2 to the crossbar 3, thus forming a figure-eight support structure for each pair of inclined support rods 1. The top of the lug 4 has a pair of C-shaped clamps, which clamp the crossbar 3. Multiple bolts are used on both sides of the two C-shaped clamps. The connection is locked, and a U-shaped ring is fixed to the bottom surface of the C-shaped clamp plate; the hook on the top of the hand chain hoist 5 is hung on the U-shaped ring at the bottom of the hanging ear 4, and the hook at the bottom of the hand chain hoist 5 is hung on the mud pump 6; the impeller at the bottom of the mud pump 6 can break up the plated mud blocks below 50mm, and the enlarged flow channel design reduces clogging, and can pump out high slag mud with a sand content of up to 15%; the flow parts are made of high chromium alloy or FRP composite material, which improves wear resistance by 3 times and extends service life by more than 50% compared with traditional equipment; The mud generated during construction is transported to a mud pit for recycling and storage. The mud level in the mud pit will fluctuate frequently due to different stages of construction. At this time, it is necessary to adjust the height of the mud pump 6 in the mud pit in time. In practice, the spacing between the bottoms of the two inclined support rods 1 in each group is adjusted according to the width of the mud pit, so that the bottoms of the two inclined support rods 1 in each group can be supported on the top of the two sides of the mud pit. The mounting ring 2 and the crossbar 3 are fixed and locked with screws, so that the crossbar 3 is fixed horizontally above the middle of the mud pit. The hook of the hand chain hoist 5 is used to lower the mud pump 6 into the mud pit. The operator controls the lifting and lowering of the hook of the hand chain hoist 5 by pulling the chain, thereby controlling the lifting and lowering of the mud pump 6. When faced with fluctuations in the mud level in the mud pit, operators only need to operate the hand-operated hoist 5 to adjust the lifting and lowering of the mud pump 6, avoiding the cumbersome process of tying, hoisting, and lowering the steel wire rope in the traditional method. This greatly reduces non-operational waiting time and ensures the continuity of construction. At the same time, timely adjustment of the height of the mud pump 6 greatly avoids damage to the mud pump 6. Moreover, the entire adjustment process is simple and can be completed independently by the operator, reducing the reliance on multiple people to cooperate and saving labor costs.

[0024] In some embodiments, such as Figures 1 to 3 As shown, each pair of mounting rings 2 has multiple positioning slots 7 and multiple positioning strips 8 fixedly connected around the end faces of the adjacent rings; the positioning slots 7 and the positioning strips 8 can engage; each pair of mounting rings 2 has clamps 9 on both sides; the clamps 9 are sleeved on the outside of the crossbar 3 and can be fixed and locked on the outside of the crossbar 3. Specifically, the positioning slots 7 and positioning strips 8 are evenly arranged around the axis of the mounting ring 2, and the number and position of the positioning slots 7 and positioning strips 8 correspond to each other, so that the positioning strips 8 can engage with the positioning slots 7; the clamp 9 includes a pair of C-shaped clamps, which are respectively clamped on both sides of the crossbar 3, and the two C-shaped clamps are locked and fixed by bolts on both sides, thus fixing the clamp 9 to the crossbar 3; the two clamps 9 are respectively located on both sides of the two mounting rings 2, fixing the position of the two mounting rings 2, thereby ensuring that the positioning strips 8 engage with the positioning slots 7; In specific operation, when it is necessary to adjust the angle between the two inclined support rods 1, loosen the clamp 9 on one side so that the clamp 9 can move along the crossbar 3 and push the clamp 9 away from the mounting ring 2 so that the two mounting rings 2 can separate. At this time, loosen the screws on the mounting ring 2 so that the fixing between the mounting ring 2 and the crossbar 3 is loosened, and push the two mounting rings 2 away from each other so that the positioning strip 8 disengages from the positioning slot 7. Adjust the angle between the two inclined support rods 1 so that the two mounting rings 2 rotate relative to each other so that the positioning strip 8 and the positioning slot 7 are aligned again. Then, push the two mounting rings 2 closer together so that the positioning strip 8 and the positioning slot 7 are engaged again. Use screws to fix and lock the mounting rings 2 and the crossbar 3 to fix the angle between the two inclined support rods 1. Then, use the clamps 9 on both sides to clamp the two mounting rings 2 together. Finally, tighten the clamps 9 to complete the entire adjustment process. By adjusting the engagement position of the two mounting rings 2, the opening angle between the two inclined support rods 1 is changed, thereby flexibly adapting to mud pits of different widths and shapes, greatly improving the versatility and application range of the equipment. The positioning clip 8 engages with the positioning slot 7, and the clamps 9 on both sides hold and fix it, forming a double fixing mode. This can effectively resist the vibration during equipment operation and prevent the two mounting rings 2 from accidentally coming loose, greatly improving the safety and stability during operation.

[0025] In some embodiments, such as Figures 1 to 6 As shown, a support leg 10 is provided at the bottom of the inclined support rod 1; a connecting plate 11 is fixedly connected to both the bottom end of the inclined support rod 1 and the top end of the support leg 10; a through hole is provided in the middle of the connecting plate 11; multiple anti-slip protrusions are evenly fixedly connected to both sides of the connecting plate 11 and around the through hole; double-headed bolts 12 are provided in the through holes of the two connecting plates 11; a rubber gasket 13 is provided between the two connecting plates 11; the double-headed bolts 12 pass through the rubber gasket 13; In specific operation, after the opening angle between the two inclined support rods 1 is adjusted, the nuts at both ends of the double-headed bolt 12 are loosened so that the two connecting plates 11 can rotate around the double-headed bolt 12, and the angle of the support leg 10 is controlled and adjusted. According to the actual ground conditions, the angle of the support leg 10 is adjusted so that it can stand completely vertically on the ground, ensuring the maximum contact area and support stability with the ground. After the support leg 10 is adjusted, tighten the nuts at both ends of the double-ended bolt 12, so that the two connecting plates 11 move closer together and squeeze the rubber pad 13 in the middle. The anti-slip ridges on the connecting plate 11 will be deeply embedded in the contact surface of the rubber pad 13 and the nut. The rubber pad 13 deforms after being compressed, which not only fills the micro gaps, but also generates huge static friction, ensuring the connection strength and positional stability between the support leg 10 and the inclined support rod 1. By adjusting the angle of the support legs 10, it can be ensured that each support leg 10 can be independently and vertically pressed into the ground. Even in uneven or sloping construction sites, it can provide a stable and level support platform for the entire equipment, effectively preventing the equipment from shaking or tipping over.

[0026] In some embodiments, such as Figures 3 to 7 As shown, the outer ring of the support leg 10 is provided with multiple mounting grooves 14; an arc-shaped strip 15 is rotatably mounted on the bottom of the mounting groove 14; the arc-shaped strip 15 can fit against the outer wall of the support leg 10; the middle part of the side of the arc-shaped strip 15 away from the support leg 10 is a planar structure; sliding grooves 16 are provided on both sides of the mounting groove 14; sliders 17 are slidably mounted inside the sliding grooves 16 on both sides; a push plate 18 is rotatably mounted between two sliders 17; the other end of the push plate 18 is rotatably connected to the arc-shaped strip 15. Specifically, the mounting groove 14 is opened along the axial direction of the support leg 10 on the outer side of the support leg 10; a circular hole is opened at the bottom of the mounting groove 14, and the circular hole penetrates the bottom of the mounting groove 14 and the outer wall of the support leg 10, and a hinge shaft is inserted inside the circular hole; an insert is fixedly connected to the bottom of the arc-shaped strip 15 near the mounting groove 14, and a through hole matching the circular hole is opened in the middle of the insert, and the hinge shaft passes through the through hole of the insert to rotatably connect the arc-shaped strip 15 and the mounting groove 14; a round rod is fixedly connected between the sliders 17 on both sides, and the round rod rotatably passes through the top of the push plate 18; the bottom of the push plate 18 is hinged to the arc-shaped strip 15; During mud pumping operations, the ground around the mud pit often becomes muddy and soft due to mud spillage. When traditional outriggers are directly supported on such ground, they are prone to sinking due to concentrated pressure, causing the entire support structure to become unstable, tilt, or even cause a collapse, posing a significant safety hazard. In operation, after the support leg 10 is placed vertically on the ground, the operator moves the arc-shaped plate 15 on the outer ring of the support leg 10, causing the arc-shaped plate 15 to rotate around the hinge axis, so that the arc-shaped plate 15 rotates to a horizontal state. The rotation of the arc-shaped plate 15 will drive the push plate 18 above to move downward. The push plate 18 will rotate accordingly and push the sliders 17 at both ends to slide downward along the slide groove 16. When the arc-shaped plate 15 rotates to a horizontal state, the insert at its bottom will contact the inner bottom surface of the mounting groove 14. At the same time, the arc-shaped plate 15, the push plate 18 and the inner wall of the mounting groove 14 form a triangular stable structure, thereby limiting the arc-shaped plate 15 to a horizontal posture, so that the outer wall of the arc-shaped plate 15 contacts the ground, forming a stable support base plate. The extended arc-shaped strip 15 significantly increases the ground contact area of ​​the support leg 10, effectively dispersing the pressure of the equipment weight on the ground. This fundamentally prevents the support leg 10 from sinking on muddy ground, ensuring the stability of the support structure throughout the operation and greatly improving construction safety.

[0027] Furthermore, such as Figures 5 to 7 As shown, a rubber sheet 19 is bolted to the side of the mounting groove 14 away from the arc-shaped strip 15; a plurality of strip-shaped protrusions 20 are uniformly fixed to the arc surface of the push plate 18 away from the arc-shaped strip 15; the strip-shaped protrusions 20 can be pressed into contact with the rubber sheet 19. Specifically, the mounting groove 14 has a groove on the side away from the arc-shaped strip 15, the rubber sheet 19 is installed in the groove, and the two sides of the rubber sheet 19 are fixedly connected to the groove by multiple screws; the top of the push plate 18 has an arc-shaped structure, and multiple strip protrusions 20 are evenly fixed on the arc-shaped surface of the top of the push plate 18, and the length direction of the strip protrusions 20 is parallel to the width direction of the push plate 18. When the arc-shaped strip 15 is moved and rotated to a horizontal position, it will drive the push plate 18 to move downward and rotate at the same time; the strip protrusion 20 on the arc surface at the top of the push plate 18 will rotate accordingly and eventually come into contact with the rubber sheet 19 at the top of the mounting groove 14 and generate compression; since the movement trajectory of the push plate 18 is determined, when the arc-shaped strip 15 reaches the horizontal limit point, the compression of the strip protrusion 20 on the rubber sheet 19 will also reach its maximum, thereby generating a continuous positive pressure between the two; The compression between the strip protrusion 20 and the rubber sheet 19 generates a huge static friction force, which can resist the tendency of the push plate 18 to move upward unexpectedly, thus providing a reliable mechanical self-locking for the arc-shaped strip 15 in a horizontal working state; it can effectively prevent the arc-shaped strip 15 from accidentally loosening or swinging back due to uneven ground, personnel collisions or equipment vibrations, ensuring the long-term stability of the support foundation and eliminating safety hazards.

[0028] In some embodiments, such as Figures 8 to 9As shown, a multi-chain sling 21 is attached to the bottom of the hook of the hand chain hoist 5; each chain of the multi-chain sling 21 is fixedly connected to the top outer wall of the mud pump 6. Specifically, the top of the multi-chain sling 21 is a truncated cone, and a U-shaped ring is fixed to the top of the truncated cone. Multiple chains are fixed to the bottom of the truncated cone. The multi-chain sling 21 is fixed to the outer ring of the mud pump 6 through the multiple chains of the multi-chain sling 21. The weight of the mud pump 6 is distributed by multiple chains of the multi-chain sling 21, which effectively avoids local stress concentration that may be caused by single-point suspension; reduces the risk of breakage due to insufficient strength of a single suspension point, and improves the safety and reliability of the lifting process. The mud pump 6 is evenly pulled from all sides by multiple chains of the multi-chain sling 21, forming a stable hoisting structure; it can effectively limit the swaying and tilting of the mud pump 6, ensuring that it always maintains the expected vertical posture.

[0029] In some embodiments, such as Figures 8 to 9 As shown, a cover 22 is bolted to the top outer ring of the multi-chain sling 21; the diameter of the cover 22 is larger than the diameter of the mud pump 6. Specifically, the baffle 22 has a cymbal-shaped structure with an opening in the middle. The opening of the baffle 22 fits onto the outer ring of the truncated cone of the multi-chain sling 21 and is secured with multiple screws. The baffle 22 effectively prevents mud from splashing onto the chain of the hand chain hoist 5, ensuring that the chain and internal mechanism of the hand chain hoist 5 remain clean and operate smoothly. This guarantees the absolute reliability of the height adjustment function of the mud pump 6, avoids work interruptions due to equipment failure, extends the service life of the equipment, and reduces maintenance costs.

[0030] In some embodiments, such as Figures 1 to 3 , Figures 10 to 11 As shown, the inclined support rod 1 has multiple positioning holes 23 evenly distributed in its middle; a sleeve rod 24 is provided between the two inclined support rods 1 on both sides; both ends of the sleeve rod 24 are rotatably fitted with threaded sleeves 25; both ends of the sleeve rod 24 are slidably fitted with screws 26; the threaded sleeves 25 and the screws 26 are threadedly engaged; the end of the screw 26 away from the sleeve rod 24 can pass through the positioning holes 23; a C-shaped fixing plate 27 and a C-shaped sliding plate 28 are fixedly connected to the end of the screw 26 away from the sleeve rod 24; the fixing plate 27 and the sliding plate 28 are respectively located on both sides of the inclined support rod 1; a nut is threaded onto the outer ring of the end of the screw 26 away from the sleeve rod 24. In practice, after the inclined support rod 1 and the crossbar 3 are installed and fixed, the nut at the end of the screw rod 26 and the sliding clamp 28 are removed from the screw rod 26. The screw rod 26 is passed through the positioning hole 23 on the inclined support rod 1. The sleeve rod 24 and the screw rod 26 are raised to the horizontal, so that the other screw rod 26 is aligned with the positioning hole 23 on the other side of the inclined support rod 1. The screw sleeves 25 at both ends of the sleeve rod 24 are rotated, driving the screw rods 26 on both sides to slide out of the screw sleeves 25, so that the other screw rod 26 is inserted into the positioning hole 23 on the other side. At this time, the two screw rods 26 are respectively inserted into the corresponding positioning holes 23 on both sides, and the arc surface of the fixing clamp 27 contacts the outer wall of the inclined support rod 1. Then, the sliding clamp 28 is put on the screw rod 26 and locked with a nut, so that the sliding clamp 28 and the fixing clamp 27 clamp the inclined support rod 1, achieving reliable fixation. An adjustable support point is added between the inclined support rods 1 on both sides by using sleeve rod 24 and screw rod 26 to form a stable triangular support structure, which effectively reduces the deformation and vibration of the support frame and ensures the stability of the mud pump 6 during operation. Since multiple positioning holes 23 are opened on the support rod, and the overall length of sleeve rod 24 and screw rod 26 is adjustable, it can flexibly adapt to different opening widths and heights of the support frame, providing a guarantee for the stable operation of the equipment under various working conditions.

[0031] In some embodiments, such as Figure 1 and Figure 10 As shown, a plurality of hanging rods 29 are fixedly arranged around the outer ring of the middle part of the sleeve rod 24; the hand chain of the hand chain hoist 5 can be hooked to the hanging rods 29; Specifically, multiple hanging rods 29 are radially fixed to the outer ring of the sleeve rod 24 around the axis of the sleeve rod 24; after the operator adjusts the height of the mud pump 6 by using the hand chain hoist 5, the hand chain of the hand chain hoist 5 is hung on the hanging rod 29. Because the ground was muddy, if the chain of the hand chain hoist 5 was dragged on the ground, it would easily get covered in mud. After the mud dried, it would cause the chain joints to stiffen, making it difficult to pull, and even damaging the internal mechanism of the hand chain hoist 5. Hanging it on the hanging rod 29 keeps the chain clean and dry at all times, ensuring that the hand chain hoist 5 is always in a ready-to-operate state and guaranteeing the absolute reliability of the lifting function.

[0032] Working principle: Based on the width of the mud pit, adjust the distance between the bottoms of the two inclined support rods 1 in each group so that the bottoms of the two inclined support rods 1 in each group can be supported on the top of the two sides of the mud pit wall respectively. Loosen the clamp 9 on one side so that the clamp 9 can move along the crossbar 3 and push the clamp 9 away from the mounting ring 2 so that the two mounting rings 2 can separate. At this time, loosen the screws on the mounting ring 2 so that the fixing between the mounting ring 2 and the crossbar 3 is loosened and the two mounting rings 2 are pushed away from each other so that the positioning strip 8 is disengaged from the positioning slot 7. Adjust the angle between the two inclined support rods 1 so that the two mounting rings 2 rotate relative to each other so that the positioning strip 8 and the positioning slot 7 are aligned again. Then, push the two mounting rings 2 closer to contact each other so that the positioning strip 8 and the positioning slot 7 are engaged again. Use screws to fix and lock the mounting ring 2 and the crossbar 3 to fix the angle between the two inclined support rods 1. Use screws to fix and lock the mounting ring 2 and the crossbar 3 so that the crossbar 3 is fixed horizontally above the middle of the mud pit. After the opening angle between the two inclined support rods 1 is adjusted, loosen the nuts at both ends of the double-headed bolt 12 so that the two connecting plates 11 can rotate around the double-headed bolt 12, control and adjust the angle of the support leg 10. Adjust the angle of the support leg 10 according to the actual ground conditions so that it can stand completely vertically on the ground, ensuring the maximum contact area and support stability with the ground. At this time, the operator moves the arc-shaped strip 15 on the outer ring of the support leg 10, causing the arc-shaped strip 15 to rotate around the hinge axis, so that the arc-shaped strip 15 rotates to a horizontal state. The rotation of the arc-shaped strip 15 will drive the push plate 18 above to move downward. The push plate 18 will rotate accordingly and push the sliders 17 at both ends to slide downward along the slide groove 16. When the arc-shaped strip 15 rotates to a horizontal state, the insert at its bottom will contact the inner bottom surface of the mounting groove 14. At the same time, the arc-shaped strip 15, the push plate 18 and the inner wall of the mounting groove 14 form a triangular stable structure. Thus, the arc-shaped strip 15 is constrained to a horizontal posture, so that the outer wall of the arc-shaped strip 15 contacts the ground, forming a stable support base plate. Next, remove the nut and sliding clamp 28 from the end of the screw 26, pass the screw 26 through the positioning hole 23 on the inclined support rod 1, raise the sleeve 24 and the screw 26 to the horizontal, so that the other screw 26 is aligned with the positioning hole 23 on the other side of the inclined support rod 1, rotate the threaded sleeves 25 at both ends of the sleeve 24, drive the screws 26 on both sides to slide out of the threaded sleeves 25, so that the other screw 26 is inserted into the positioning hole 23 on the other side; at this time, the two screws 26 are respectively inserted into the corresponding positioning holes 23 on both sides, and the arc surface of the fixing clamp 27 contacts the outer wall of the inclined support rod 1; then put the sliding clamp 28 on the screw 26 and lock it with the nut, so that the sliding clamp 28 and the fixing clamp 27 clamp the inclined support rod 1 to achieve reliable fixation; The mud level in the mud pit fluctuates frequently due to different stages of construction. Therefore, it is necessary to adjust the height of the mud pump 6 within the mud pit in a timely manner. Operators control the lifting and lowering of the mud pump 6 by pulling the chain of the hand chain hoist 5, thereby controlling the hoist's hook. This avoids the cumbersome processes of tying, hoisting, and lowering the mud pump 6 in traditional methods, greatly reducing non-operational waiting time and ensuring construction continuity. Simultaneously, timely adjustment of the mud pump 6's height significantly reduces the risk of damage. Furthermore, the entire adjustment process is simple and can be completed independently by the operator, reducing reliance on multiple collaborators and saving labor costs.
