Description
Technical Field
[0001] This utility model relates to the field of construction machinery technology, specifically to a slag removal and wall brushing device for underground continuous wall joints. Background Technology
[0002] As a critical support structure in deep foundation pit engineering, the construction quality of the joints of diaphragm walls directly affects the wall's impermeability and overall stability. During actual trenching and concrete pouring, mud, sediment, and other impurities easily remain at the joints. If not thoroughly cleaned, this can lead to loose connections in the subsequent wall structure, and even cause leakage risks, seriously affecting the safety and durability of the project. Therefore, the joint cleaning process is a crucial step in ensuring the quality of diaphragm walls.
[0003] Currently, common slag removal methods mostly rely on manual operation of wire brushes or high-pressure water guns, which suffer from low efficiency, incomplete cleaning, and high labor intensity. While some mechanical slag removal devices can improve work efficiency to some extent, they often struggle to adapt to trench sections of varying widths and depths, and cannot reach into complex crevices to complete cleaning. Especially in complex conditions such as irregular joints or ring-shaped pile foundations, existing mechanical slag removal devices lack flexibility and have limited cleaning effectiveness.

[0037] Example 1
[0038] This embodiment provides a slag removal and wall brushing device for underground continuous wall joints. The device can move freely in the gaps of the underground continuous wall joints and brushes and washes the wall while moving through the sweeping component 3 and the spraying component 4, thereby removing residual mud and sediment to keep the wall surface clean.
[0039] Specifically, such as Figure 1 As shown, the slag removal and wall brushing device for the underground continuous wall joint in this embodiment includes a machine body 1, a moving component 2, a sweeping component 3, and a spraying component 4. The moving component 2 includes at least one pair of traveling wheels symmetrically installed on the middle section of the side wall of the machine body 1 with the wheel surfaces facing outwards, and a distance adjustment device for adaptively adjusting the distance between the two traveling wheels according to the wall spacing. The traveling wheels mainly include a mounting base 22, rollers 21, and a first motor. The rollers 21 are rotatably connected to the mounting base 22, and the first motor drives the rollers 21 to rotate. In practical applications, the first motor can be a hub motor or a wheel-side motor.
[0040] Two mounting seats 22 are fixed to the machine body 1 by a distance adjustment component 5. The distance adjustment component 5 controls the extension and retraction of the mounting seats 22 on both sides, thereby changing the distance between the two traveling wheels. When the distance between the two walls traversed by the slag-cleaning and wall-brushing device is narrow, the distance adjustment component 5 can control the two mounting seats 22 to retract appropriately. Conversely, when the distance between the two walls traversed by the slag-cleaning and wall-brushing device is widened, the distance adjustment component 5 can appropriately expand the two mounting seats 22, thereby ensuring that the two traveling wheels always press against the walls on both sides. In the contact state, when the first motor drives the roller 21 to rotate, the roller 21 can drive the machine body 1 to move along the wall.
[0041] In this embodiment, the moving component 2 adaptively extends and retracts the mounting bases 22 on both sides via a distance adjustment device to adapt to walls with different spacing. Furthermore, the traveling speed and direction of the main body 1 can be controlled by adjusting the rotational speed and steering of the two traveling wheels. Specifically, in a groove formed by two parallel straight walls, the two traveling wheels can be controlled to operate synchronously to pass through the groove. However, in grooves formed by curved walls, corresponding to certain special pile foundation projects, the two traveling wheels can be controlled to operate at different speeds to pass through the groove.
[0042] like Figure 2 As shown, in order to achieve adaptive adjustment of the distance between the two traveling wheels, at least two inwardly extending fixing grooves are provided in the middle section of the corresponding side wall of the body 1 in this embodiment. The two fixing grooves are located on both sides of the body 1 and are respectively located in the direction of the line connecting the two traveling wheels. Based on this, the distance adjustment component 5 used in this embodiment includes a slider 51 and a first spring 52 installed in each fixing groove. The cross-sectional shape of the slider 51 matches the fixing groove and its length is shorter than the fixing groove. This embodiment does not limit the interface shape between the slider 51 and the fixing groove. In practical applications, it can be circular or square. The cross-sectional shape of the slider 51 is preferably square, so that the slider 51 can only slide along the extension direction of the fixing groove, restricting the spin motion of the slider 51 in the fixing groove. The two ends of the first spring 52 are fixedly connected to the inner side of the slider 51 and the inner wall of the fixing groove, respectively; the other side of the slider 51 is fixedly connected to the mounting base 22 of the traveling wheel. In a preferred embodiment, in order to enable the walking wheel to rotate relative to the body 1 and thus achieve steering, the slider 51 and the mounting base 22 of the walking wheel can be detachably connected to facilitate manual adjustment of the forward direction of the walking wheel. Alternatively, a drive mechanism can be used to rotatably connect the two to achieve active steering.
[0043] Based on the above structure, assuming that the distance between the ends of the two traveling wheels is D when the two first springs 52 are in their natural state, the slag-cleaning and wall-brushing device provided in this embodiment can only travel within gaps with a spacing less than D. Specifically, as the gap traversed by the slag-cleaning and wall-brushing device becomes narrower, the force exerted on the two traveling wheels towards the center increases, and the pressure exceeds the spring force, thus compressing the two first springs 52. This reduces the distance between the two traveling wheels to adapt to the change in gap spacing. Correspondingly, as the gap traversed by the slag-cleaning and wall-brushing device becomes wider (still less than D), the pressure on the two traveling wheels gradually decreases, and the spring force exceeds the pressure, causing the two first springs 52 to gradually recover their deformation. This increases the distance between the two traveling wheels to adapt to the change in gap spacing.
[0044] Furthermore, this embodiment can also use the line connecting the two traveling wheels as an axis, driving the two traveling wheels to rotate as a whole, thereby adjusting the direction of travel and cleaning angle of the slag-cleaning and wall-brushing device, and enabling it to flexibly travel along various complex paths within the tank section. For example, by adjusting the travel direction, it can travel along a spiral line between annular gaps, thus significantly improving cleaning efficiency. To achieve flexible steering function between the two traveling wheels, such as... Figure 3 As shown, in this embodiment, each slider 51 is fixedly connected to a steering motor 23. The steering motor 23 can be embedded in the slider 51 or fixedly connected to the outward-facing end of the slider 51. A connecting ring 24 is provided in the mounting base 22 of the traveling wheel near the distance adjustment device, and the connecting ring 24 is keyed to the output shaft of the steering motor 23. Based on this, the two traveling wheels can rotate independently about the direction of their connection, thereby achieving synchronous or asynchronous adjustment of the traveling direction of the two traveling wheels. To achieve precise adjustment of the traveling wheel direction, the steering motor 23 in this embodiment can be a stepper motor or a servo motor.
[0045] like Figure 1 As shown, the cleaning assembly 3 in this embodiment includes multiple cleaning brushes mounted circumferentially on the body 1. Each cleaning brush includes a brush arm 32 and a wheel-shaped brush head 31 rotatably connected to its end, as well as a second motor that drives the brush head 31 to rotate. In this embodiment, each cleaning brush extends radially outward from the body 1 in its natural state. When the body 1 moves forward along a horizontal plane, the ends of each cleaning brush can just contact the wall. In this embodiment, the brush head 31 includes a wheel-shaped brush disc and multiple brush plates evenly distributed outside the brush disc and arranged radially. The brush plates in this embodiment can be made of a relatively hard resin material with good flexibility, thereby cleaning the wall surface by scraping it during rotation. In other embodiments, the brush plates on the outer periphery of the brush disc can also be replaced with metal bristles, thereby cleaning the wall surface by the rotation of the brushes during the rotation of the brush head 31. Similar to the first motor, the second motor in this embodiment can also be a hub motor or a wheel-side motor.
[0046] In this embodiment, the length of the brush arm 32 can be flexibly set as needed. The outward-facing end of the brush arm 32 is connected to the brush head 31, while the other end of the brush arm 32 is rotatably connected to the machine body 1 via a rotating joint. This rotating joint allows the brush arm 32 to rotate along the plane of the machine body 1. Specifically, the cleaning assembly 3 also includes a first elastic element for limiting and resetting the rotation angle of the brush arm 32. In this state, when the slag-cleaning brush wall device passes through a dynamically changing gap, each brush arm 32 can rotate along the rotating joint, dynamically adjusting the spacing of the brush heads 31 on both sides by changing the angle of the brush arm 32 to adapt to the changes in the gap. The function of the first elastic element is to apply prestress to the brush arm 32 to achieve angle adjustment.
[0047] like Figure 4 As shown, the rotating joint in this embodiment includes a limiting shaft on one side of the body 1 and a bushing 300 located at the end of the brush arm 32; the extending direction of the limiting shaft is perpendicular to the plane of the body 1, and the bushing 300 is sleeved on the limiting shaft. In this embodiment, a torsion spring 301 can be provided between the limiting shaft and the bushing 300 of the rotating joint as a first elastic element to achieve angle limitation and reset. In its natural state, the brush arms 32 on both sides are at their maximum opening angle. As the gap traversed by the slag-cleaning brush wall device gradually narrows, the brush head 31 at one end of the two brush arms 32 is subjected to inward pressure and folds inward. During this process, as the angle between the brush arm 32 and the body 1 decreases, the torsion spring 301 is compressed and deformed, thereby creating a tendency for the brush arm 32 to unfold outward. In this situation, when the gap passed by the slag cleaning brush device widens again, the deformation of the torsion spring 301 automatically recovers and applies an outward elastic force to each brush arm 32, making the angle between the brush arm 32 and the body 1 larger, and the brush heads 31 on both sides expand outward.
[0048] For the same purpose, in other embodiments, a diagonal spring fixedly connected to the machine body 1 can be provided on both sides of the rotation plane of the brush arm 32 as the first elastic element for angle limitation and reset. When the two diagonal springs are in their natural state, the brush arm 32 is in a preset equilibrium position. As the gap through which the slag-cleaning brush device passes gradually narrows, and the brush arms 32 on both sides fold inward, the inner diagonal spring is compressed, while the outer diagonal spring is stretched; this gives the brush arm 32 a tendency to reset outward. In this case, when the gap through which the slag-cleaning brush device passes widens again, the deformation of the inner and outer diagonal springs automatically recovers, and an outward elastic force is applied to each brush arm 32, making the angle between the brush arm 32 and the machine body 1 larger, and the brush heads 31 on both sides expand outward.
[0049] Therefore, the first elastic element in this embodiment can adaptively adjust the opening angle of the brush arms 32 on both sides as the width of the gap changes, thereby ensuring that the brush head 31 can always be in close contact with the walls on both sides, thus improving the cleaning effect.
[0050] The spray assembly 4 in this embodiment includes a nozzle 41 mounted on each brush head 31 and a water supply pipe 42 connecting each nozzle 41. The spray direction of the nozzle 41 points outward from the brush head 31. In practical applications, the water supply pipe 42 first extends to the center of the body 1, and then extends along the brush arm 32 to each brush head 31 through multiple branch pipes. In this embodiment, to accommodate the angle adjustment function of the brush arm 32, the water supply pipe 42 in this invention can be a flexible hose. In addition, the body 1 and the brush arm 32 are provided with limiting sleeves for fixing the flexible hose; the water supply pipe 42 passes through the limiting sleeves and fits tightly against the surface of the body 1. The end of the water supply pipe 42 is provided with a flange for connecting a water pump for quick assembly and disassembly.
[0051] In the spray assembly 4 of the wall cleaning brush device in this embodiment, the other end of the water supply pipe 42 is used to connect the water pump and the water source. Both the water pump and the water source are external components of the device in this embodiment. When it is necessary to perform spray cleaning while the brush head 31 is cleaning the wall, the water pump is started to pump cleaning agent or clean water to the spray head 41. The cleaning agent or clean water will be sprayed outward along the spray head 41 under water pressure. In order to achieve cleaning at a distance, the water supply pipe 42 used in this embodiment is relatively long; in practical applications, the water supply pipe 42 can also be used in conjunction with a water pipe cart. When the machine body 1 moves to a distance, the water pipe cart releases the pipe, and when the machine body 1 approaches the water pump, the water supply pipe 42 is wrapped and stored by the water pipe cart.
[0052] Figure 1 In practical application, the slag-cleaning and wall-brushing device shown is lowered into the trench section of the diaphragm wall by the operator, who then activates the wheels and cleaning components 3. The wheels roll along the trench wall, moving the entire device from top to bottom or bottom to top. During movement, when encountering obstacles, uneven walls, or environments with varying cross-sections, the moving components 2 and cleaning components 3 on the machine body 1 retract and fold due to inward forces. Under the action of the elastic elements with reset functions, they maintain a constant pressure against the wall surface, ensuring the stability of the machine body 1 and tight contact. This results in a more uniform and thorough cleaning effect, avoiding cleaning dead spots caused by uneven walls. Simultaneously, the cleaning components 3 around the perimeter are activated to thoroughly scrub the joints of the trench wall. The rotating brush head 31 mechanically scrapes the wall surface, while the high-pressure jet from the nozzle 41 disperses and softens stubborn dirt, achieving a coordinated "flushing and cleaning" operation that significantly improves slag removal efficiency and cleanliness.
[0053] In summary, using the device of this embodiment to replace manual cleaning of diaphragm wall joints can greatly improve work efficiency and reduce the labor intensity and operational risks for workers. Compared with conventional cleaning methods, the slag removal and wall brushing device of this embodiment is not only more efficient and has a better cleaning effect, but also has good adaptability, effectively handling various complex diaphragm wall joint task scenarios, and has higher practical value.
[0054] Example 2
[0055] Based on the solution in Embodiment 1, this embodiment provides a further optimized solution, such as... Figure 5 As shown, in this embodiment, at least one slot is provided at the bottom of the machine body 1; the slag cleaning and brushing device also includes at least one support component 6. Each support component 6 includes a support arm 61 and a roller 21 at its bottom, and a quick-release connector is provided at the top of the support arm 61. The support component 6 is vertically connected to the bottom of the machine body 1 and locked by inserting the quick-release connector of the support arm 61 into the slot.
[0056] In practical applications, when encountering smooth tank walls or work scenarios requiring additional support to prevent equipment from shaking, the support component 6 in the slag cleaning and brushing device of this embodiment can be installed into the slot; through the contact between the roller 21 at the bottom of the support arm 61 and the bottom of the tank or the other side wall, the support arm 61 and the two traveling wheels can form a stable three-point support structure, effectively preventing the equipment from tipping over or swinging during the cleaning process, further ensuring the safety of the operation process and the stability of the cleaning effect.
[0057] To enable quick assembly and disassembly of support component 6, such as Figure 6 As shown, the slot on the body 1 includes a slot that matches the cross-sectional shape of the support arm 61, and inwardly extending limiting grooves on two opposing side walls inside the slot. Correspondingly, the top side of the support arm 61 has two mounting grooves corresponding to the positions of the limiting grooves. The quick-release connector includes two outwardly retractable limiting protrusions 62 disposed within the mounting grooves, and a switch assembly on the support arm 61 for controlling the extension and retraction of the limiting protrusions 62. When the switch assembly is in the locked state, the two limiting protrusions 62 extend outward along the support arm 61 and engage with the limiting grooves; when the switch assembly is in the unlocked state, the two limiting protrusions 62 retract inward along the support arm 61 and disengage from the limiting grooves. Specifically, as... Figure 6 As shown, the structure and principle of the switch assembly in this embodiment for locking and unlocking the quick-release connector are as follows:
[0058] The inner side of the limiting protrusion 62 is fixedly connected to the inner wall of the mounting groove by the second spring 65. When the second spring 65 is in its natural state, the two limiting protrusions 62 extend out of the support arm 61. A sliding groove is provided on the side wall of the support arm 61 along the extension direction of the support arm 61. The switch assembly includes a lever 63 that engages with the sliding groove and can slide along the sliding groove, and a T-shaped pull rope 64. A cavity can be provided in the center of the support arm 61 to allow the pull rope 64 to pass through. The two lateral ends of the pull rope 64 are respectively connected to the inner sides of the two limiting protrusions 62, and the two lateral ends of the pull rope 64 are taut when the two second springs 65 are in their natural state. The vertical end of the pull rope 64 is fixedly connected to the lever 63, and the two vertical ends of the pull rope 64 are taut when the lever 63 is at the top of the sliding groove.
[0059] Based on the above structure, when the lever 63 is at the top of the slide groove, the pull rope 64 is not under force, the two second springs 65 are in their natural state, and the limiting protrusion 62 extends outward from the side of the support arm 61. When the user presses the lever 63 and slides it to the bottom of the slide groove, the pull rope 64 is under force, causing the two limiting protrusions 62 to be pulled towards the center of the support arm 61. The limiting protrusions 62 retract into the mounting groove inside the support arm 61, and the two second springs 65 are in a compressed state at this time. In this state, when the user releases the lever 63, the two second springs 65 return to their original deformation, popping the limiting protrusions 62 out of the mounting groove and causing the lever 63 to return to the top of the slide groove.
[0060] Therefore, when installing the support assembly 6, the user can first press the lever 63 and slide it to the bottom of the groove, causing the two limiting protrusions 62 to retract into the mounting slot. Then, the support arm 61 is inserted into the slot of the body 1. After it is in place, the lever 63 is released, the limiting protrusions 62 pop out and lock with the body 1, and the lever 63 returns to the top of the groove. When it is necessary to remove the support assembly 6, the user can first press the lever 63 and slide it to the bottom of the groove, causing the two limiting protrusions 62 to retract into the mounting slot, releasing the locking relationship between the support arm 61 and the body 1, and then pull the support arm 61 out of the slot of the body 1.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
