Description

Technical Field

[0001] This invention relates to the field of mud extraction technology, and in particular to a mud extraction device for construction engineering. Background Technology

[0002] In the field of engineering and construction, buildings require a stable foundation. The construction of the foundation requires drilling holes in the foundation pit, followed by driving pipe piles into the holes for subsequent construction. However, if pipe piles are not driven into the holes in time after drilling, rainwater and silt will flow into the holes during windy and rainy weather, causing the holes to be filled with mud. This muddy water will fill the entire hole, affecting the driving of pipe piles. Therefore, it is necessary to extract the mud from the holes.

[0003] Most existing mud extraction devices extract most of the water from the borehole and then use an extraction cylinder to extract the mud. However, since the mud still contains a certain amount of water, when the mud in the extraction cylinder is poured onto the collection truck, water carrying mud drips onto the area around the extraction truck, making the construction site environment too muddy. At the same time, during the extraction process, there may be some clumps of soil in the mud, which will affect the extraction effect. Therefore, how to reasonably solve this problem is something we need to consider. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mud extraction device for construction engineering. After each mud extraction, the device can compress the mud to reduce residual water, thereby preventing water from causing the mud to drip everywhere. At the same time, the device can break up clumps of soil by using a crushing rod, thus preventing clumps of soil from being unable to enter the extraction cylinder and allowing the mud to be discharged quickly. In addition, the device has an indicator light to indicate the depth of remaining mud when the extraction is almost complete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mud extraction device for construction engineering includes an extraction cylinder, an extraction groove at the lower end of the extraction cylinder, a sealing component at the opening of the extraction groove, a threaded rod rotatably connected to the top of the extraction groove, a threaded sleeve threadedly connected to the threaded rod, a rectangular plate fixedly connected to the lower end of the threaded sleeve, a movable plate slidably connected to the extraction groove, a drive motor installed at the upper end of the extraction cylinder, the output shaft of the drive motor extending into the extraction cylinder and fixedly connected to a third gear, a fourth gear cooperating with the third gear on the threaded rod, and a first one-way bearing between the fourth gear and the threaded rod.

[0006] Preferably, the sealed assembly includes horizontal boxes disposed on the left and right sides of the extraction cylinder. Each of the two horizontal boxes has a first electromagnet on its opposite inner wall. Each of the two horizontal boxes has a partition slidably connected inside. The adjacent surfaces of the two partitions and the corresponding first electromagnets are elastically connected by a first spring. Each of the two partitions has multiple drain outlets, and each drain outlet has filter cotton inside. The adjacent surfaces of the two partitions extend into the extraction tank.

[0007] Preferably, a folding airbag is fixedly connected between adjacent surfaces of the rectangular plate and the movable plate. The upper end of the folding airbag is connected to a short tube. A vertical box is provided on the left side of the extraction cylinder. A slider is slidably connected inside the vertical box. The lower end of the slider is elastically connected to the inner bottom of the vertical box through a second spring. A connecting tube is connected to the top space of the vertical box. The connecting tube and the short tube are connected through a flexible tube.

[0008] Preferably, a resistive sheet is provided on the left inner wall of the vertical box, a conductive sheet is provided on the right inner wall of the vertical box, and a cooperating conductive block is provided at the lower end of the slider and at the inner bottom of the vertical box.

[0009] Preferably, an indicator light is installed at the upper end of the extraction cylinder, and a hanging ring is fixedly connected to the upper end of the extraction cylinder.

[0010] Preferably, a telescopic rod is fixedly connected to the end of the output shaft of the drive motor, the telescopic end of the telescopic rod passes through the rectangular plate and is fixedly connected to a first gear, a rectangular block is fixedly connected to the lower end of the rectangular plate, a second gear is provided on the outer wall of the rectangular block, and a second one-way bearing is provided between the second gear and the rectangular block.

[0011] Preferably, the rectangular block has a movable cavity, the top of the movable cavity has a second electromagnet, a connecting block is slidably connected in the movable cavity, the adjacent surfaces of the connecting block and the second electromagnet are elastically connected by a third spring, the lower end of the connecting block is fixedly connected to a vertical rod, the lower end of the vertical rod passes through the movable plate, and the outer wall of the vertical rod is provided with a plurality of breaking rods along its axial direction.

[0012] The present invention has the following beneficial effects: 1. Compared with the existing technology, by setting the threaded rod and threaded sleeve, the rectangular plate can drive the moving plate to move down when the drive motor runs counterclockwise, thereby squeezing the mud in the extraction tank, reducing the residual water in the mud, thus avoiding the situation that the extraction mud will make the surrounding environment of the building too muddy, and also making it easier to quickly and completely discharge the extracted mud later. 2. Compared with the existing technology, by setting up the crushing rod, multiple crushing rods can rotate during the clockwise operation of the drive motor, thereby breaking up larger clumps of soil. This avoids the situation where the soil is too large and affects the closure of the sealing component, resulting in the inability to extract the mud. 3. Compared with existing technologies, by setting up resistive elements and indicator lights, it is possible to determine whether the extraction tank is full of mud by the brightness of the indicator lights during the mud extraction process, and at the same time, to determine the depth of the remaining mud when the mud extraction is almost complete.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] Reference Figures 1-5A mud extraction device for construction engineering includes an extraction cylinder 1, an extraction groove 2 at the lower end of the extraction cylinder 1, a sealing component at the opening of the extraction groove 2, a threaded rod 29 rotatably connected to the top of the inner side of the extraction groove 2, a threaded sleeve 30 threadedly connected to the threaded rod 29, a rectangular plate fixedly connected to the lower end of the threaded sleeve 30, a sliding plate 10 slidably connected to the inner side of the extraction groove 2, a drive motor 26 installed at the upper end of the extraction cylinder 1, and a third gear 27 fixedly connected to the end of the output shaft of the drive motor 26 extending into the extraction cylinder 1. The 9th gear is equipped with a fourth gear 28 that meshes with the third gear 27. A first one-way bearing is provided between the fourth gear 28 and the threaded rod 29. When the output shaft of the drive motor 26 drives the third gear 27 to rotate counterclockwise, the third gear 27 drives the fourth gear 28 to rotate clockwise, thereby causing the fourth gear 28 to drive the threaded rod 29 to rotate clockwise. When the output shaft of the drive motor 26 drives the third gear 27 to rotate clockwise, the third gear 27 drives the fourth gear 28 to rotate counterclockwise. At this time, the fourth gear 28 cannot drive the threaded rod 29 to rotate.

[0017] The sealed assembly includes horizontal boxes 4 arranged on the left and right sides of the extraction cylinder 1. Each horizontal box 4 has a first electromagnet 5 on its opposite inner wall. Each horizontal box 4 has a partition 7 slidably connected inside. The side of the partition 7 closest to the corresponding first electromagnet 5 is magnetic. When the first electromagnet 5 is energized, it repels the adjacent surface of the corresponding partition 7. The two partitions 7 are elastically connected to the adjacent surfaces of the corresponding first electromagnet 5 by a first spring 6. Each partition 7 has multiple drain outlets, and each drain outlet contains filter cotton. The adjacent surfaces of the two partitions 7 extend into the extraction tank 2.

[0018] In this system, a folded airbag 11 is fixedly connected to the adjacent surfaces of the rectangular plate and the movable plate 10. A short tube is connected to the upper end of the folded airbag 11. A vertical box 16 is located on the left side of the extraction cylinder 1. A slider 19 is slidably connected inside the vertical box 16. The lower end of the slider 19 is elastically connected to the inner bottom of the vertical box 16 via a second spring 18. A connecting tube 12 is connected to the top space of the vertical box 16. The connecting tube 12 and the short tube are connected via a flexible tube 13. A resistor 17 is located on the left inner wall of the vertical box 16, and a conductive sheet is located on the right inner wall of the vertical box 16. Wires are connected to the lower ends of both the resistor 17 and the conductive sheet. An external power supply is provided. The external power supply, resistor 17, slider 19, conductive sheet and indicator light 14 form a circuit through wires. The more the slider 19 moves down, the shorter the length of resistor 17 connected in the circuit, and the greater the current through indicator light 14. The lower end of slider 19 and the inner bottom of vertical box 16 are provided with mutually cooperating conductive blocks 25. A remote control switch is provided. The external power supply, remote control switch, two conductive blocks 25, first electromagnet 5, second electromagnet 23 and solenoid valve form a circuit through wires. The remote control switch and two conductive blocks 25 are connected in parallel in the circuit.

[0019] An indicator light 14 is installed at the upper end of the extraction cylinder 1, and a hanging ring 15 is fixedly connected to the upper end of the extraction cylinder 1.

[0020] The output shaft of the drive motor 26 is fixedly connected to a telescopic rod 3. The telescopic end of the telescopic rod 3 passes through a rectangular plate and is fixedly connected to a first gear 20. A rectangular block 22 is fixedly connected to the lower end of the rectangular plate. A second gear 21 is provided on the outer wall of the rectangular block 22. A second one-way bearing is provided between the second gear 21 and the rectangular block 22. When the output shaft of the drive motor 26 drives the first gear 20 to rotate clockwise, the first gear 20 drives the second gear 21 to rotate counterclockwise, thereby causing the second gear 21 to drive the rectangular block 22 to rotate clockwise. When the output shaft drives the first gear 20 to rotate counterclockwise, the first gear 20 drives the second gear 21 to rotate clockwise. At this time, the second gear 21 cannot drive the rectangular block 22 to rotate. The rectangular block 22 has a moving cavity. The top of the moving cavity is equipped with a second electromagnet 23. A connecting block is slidably connected in the moving cavity. The connecting block is made of iron material. The adjacent surfaces of the connecting block and the second electromagnet 23 are elastically connected by a third spring 24. The lower end of the connecting block is fixedly connected to a vertical rod 8. The lower end of the vertical rod 8 passes through the moving plate 10. The outer wall of the vertical rod 8 is provided with multiple breaking rods 9 along its axial direction.

[0021] The functional principle of this invention can be explained by the following operation: When extracting mud, the extraction cylinder 1 is vertically placed into the borehole using the hook on the hoisting equipment. At the same time, the drive motor 26 is started, causing the output shaft of the drive motor 26 to rotate clockwise. Due to the setting of the first one-way bearing, the clockwise rotation of the output shaft of the drive motor 26 will drive the telescopic rod 3 to rotate, while the threaded rod 29 will not rotate. At this time, the rotation of the telescopic rod 3 drives the rectangular block 22 to rotate through the first gear 20 and the second gear 21, thereby causing the vertical rod 8 to drive multiple crushing rods 9 to rotate. During the process of adding mud into the extraction cylinder 1, the mud will enter the extraction tank 2, thereby causing the rotation of the crushing rod 9 to break up larger pieces of soil, preventing the subsequent sealing component from sealing the opening of the extraction tank 2 and causing any impact. During the process of the mud entering the extraction tank 2, the moving plate 10 will move upward to compress the folded airbag 11, causing the gas in the folded airbag 11 to be forced into the top space of the vertical box 16, increasing the gas volume and air pressure in the top space of the vertical box 16. This causes the slider 19 to move downward, thereby shortening the length of the resistor 17 connected to the circuit. This increases the current through the indicator light 14 and increases the brightness of the indicator light 14. When the slider 19 moves downward to the point where the two conductive blocks 25 are in contact, the two first electromagnets 5 and the second electromagnet 23 will be energized, and the brightness of the indicator light 14 will reach its maximum. When the second electromagnet 23 is energized, it will attract the connecting block, causing the vertical rod 8 to move multiple breaking rods 9 upward. At the same time, when the two first electromagnets 5 are energized, they will repel the corresponding partitions 7, causing the two partitions 7 to move relative to each other and seal the opening of the extraction slot 2. At this time, the staff can control the drive motor 26 to turn off, and then lift the extraction cylinder 1 with the hoisting equipment. When the extraction cylinder 1 is completely separated from the mud, the output shaft of the drive motor 26 can be controlled to rotate counterclockwise, so that the rectangular block 22 does not rotate and the threaded rod 29 rotates clockwise. The clockwise rotation of the threaded rod 29 drives the threaded sleeve 30 to move down. Since the two conductive blocks 25 are in contact, the solenoid valve on the connecting pipe 12 is also in the energized state. The connecting pipe 12 is sealed, so that the downward movement of the threaded sleeve 30 will drive the rectangular plate and the moving plate 10 to move down, squeezing the mud. At this time, the water in the mud will fall into the borehole after being filtered by the filter cotton, and the mud and other substances in the mud will remain in the extraction cylinder 1. It is worth mentioning that as the mud is continuously extracted, the water in the borehole will increase. Therefore, it is necessary to use pumping equipment regularly to extract the water from the surface of the borehole to facilitate the subsequent extraction of mud. When the extraction cylinder 1 moves above the collection vehicle, the first electromagnet 5 can be de-energized and the second electromagnet 23 can be de-energized, thereby opening the slot of the extraction tank 2. Then, the output shaft of the drive motor 26 is controlled to rotate counterclockwise to quickly discharge the mud. After the mud is discharged, the handle is turned to reset the threaded sleeve 30 and the rectangular plate. During the reset process, the solenoid valve on the connecting pipe 12 is de-energized, thereby resetting the slider 19. It is worth mentioning that when there is less mud in the borehole, the extraction cylinder 1 is completely placed into the mud. The lower end of the extraction cylinder 1 will contact the bottom of the borehole, resulting in less mud entering the extraction tank 2. This causes the slider 19 to move down a shorter distance. At this time, the operator can judge the depth of the remaining mud by the brightness of the indicator light 14. Since the two conductive blocks 25 cannot contact each other, the operator needs to use the remote control switch to control the first electromagnet 5, the second electromagnet 23 and the solenoid valve.
