Description

Technical Field

[0001] This invention relates to the field of large anchor foundation construction technology, specifically to a gravity-assisted diaphragm wall cleaning device and cleaning method. Background Technology

[0002] With the maturity and advancement of construction technology, diaphragm walls (or simply diaphragm walls) are increasingly used in the foundations of large bridges, and are showing a strong trend of replacing caisson foundations and pile foundations in ultra-deep and ultra-large foundations. The shaft-type composite diaphragm wall foundation uses the diaphragm wall construction method to build the wall, connecting wall segments into a compartment with a rectangular, polygonal, or circular top view. After excavating the original soil inside the compartment, underwater bottom sealing concrete pouring is required to form a unified structure between the bottom of the compartment and the diaphragm wall. To ensure a stable bond between the bottom sealing concrete and the diaphragm wall, and to prevent water seepage or sudden surges at the joints that could affect subsequent construction progress and anchorage quality, it is necessary to specifically clean the mud and loose gravel adhering to the diaphragm wall compartment wall surface.

[0003] Patent publication number "CN112705500A" discloses a wall-mounted floor scrubber, comprising a drive box. The drive box is a rectangular box-shaped structure with an opening on one side. A motor is mounted on the outer side of the drive box. The motor's power output shaft extends into the drive box and is axially fixed to the drive shaft as a whole. The end of the drive shaft extends axially out of the drive box and is axially fixed to the cleaning disc as a whole. A drive arm is radially fixedly mounted on the drive shaft, and a drive linkage that can rotatably connect and cooperate with the end of the drive arm is fixedly mounted thereto.

[0027] In another aspect, the present invention provides a method for cleaning a wall-mounted floor using any of the gravity-assisted wall-mounted cleaning devices described above. The cleaning method includes the following steps:

[0028] S1. The guide support mechanism is vertically installed on the compartment base;

[0029] S2. Use the center of gravity adjustment mechanism to adjust the center of gravity of the whole connected with the guide support mechanism to be in the space between the guide support mechanism and the partition wall to be cleaned, so that the top of the guide support mechanism tilts towards the partition wall and is fixed on the partition wall under the action of gravity.

[0030] S3. Use the cleaning mechanism to clean the compartment walls, and simultaneously raise and lower the sliding lifting mechanism to ensure that the cleaning mechanism thoroughly cleans the compartment walls vertically.

[0031] Further, step S2 includes using a first driving device to drive the swing arm to rotate around the hinge towards the compartment wall, so that the center of gravity of the whole connected with the guide ladder beam shifts towards the compartment wall, the bottom end of the guide ladder beam is fixed so that the top end tilts towards one side of the compartment wall, and the swing arm tail cone on the swing arm is inserted and fixed on the compartment wall.

[0032] The advantages of this invention include: 1. The center of gravity of the guide support mechanism can be shifted towards one side of the compartment wall through the center of gravity adjustment mechanism, thereby tilting and fixing the top of the guide support mechanism to the compartment wall, which can stably fix the top of the guide support mechanism to the wall, so that the cleaning mechanism can apply sufficient pressure to the wall for effective cleaning; the lifting mechanism can drive the cleaning mechanism to move up and down to achieve comprehensive cleaning of the wall; this device is easy to use, has good cleaning effect, and high work efficiency.

[0033] 2. The center of gravity adjustment mechanism is hinged to the guide support mechanism. The center of gravity of the mechanism can be adjusted by rotating around the hinge. This method makes it simpler to adjust the center of gravity.

[0034] 3. The swing arm can rotate around the hinge to adjust the center of gravity of the whole connected with the guide support mechanism, and can be used with the first drive device to drive the swing arm to rotate; the tail cone of the swing arm can be inserted and fixed to the wall of the compartment to stably fix the top of the guide support mechanism to the wall.

[0035] 4. The lifting mechanism can be slidably connected to the guide rail via a vertical slider, and can be longitudinally slidably connected to the cleaning mechanism via a mounting bracket; the lifting mechanism can be driven to rise and fall via a second drive device.

[0036] 5. The sliding fastener is longitudinally slidably connected to the mounting bracket. The sliding fastener is driven to slide by the third drive device, so that the cleaning component set on the sliding fastener always exerts positive pressure on the wall during the lifting process, and sticks to the wall to achieve cleaning power.

[0037] 6. The cleaning base allows for the installation of brushing components and sliding installation of flushing components, which can improve the cleaning effect through dual cleaning operations.

[0038] 7. The guide ladder beam serves as a support column and is relatively long, making it easy to adjust the center of gravity. The fixed bottom cone can be inserted and fixed to the compartment base. The swing arm base is used to hinge the center of gravity adjustment mechanism and can also be used to hoist the guide ladder beam.

[0039] 8. The two columns connected by the crossbeam form a guide ladder beam, which supports the lifting mechanism and has high stability. The two columns are equipped with guide rails. The use of double rails can improve the stability of the lifting mechanism during sliding and prevent lateral deviation.

[0040] 9. The verticality of the guide support mechanism, i.e., the angle with the vertical direction of space, can be detected by the tilt sensor, which facilitates the adjustment of the center of gravity of the guide support mechanism.

[0041] 10. The cleaning method of the present invention uses a gravity-assisted wall-mounted cleaning device to clean the partition wall. After adjusting the center of gravity of the entire cleaning device and fixing the bottom end of the guide support mechanism, the top end of the guide support mechanism is tilted towards one side of the partition wall and fixed on the partition wall, so that the cleaning mechanism generates sufficient pressure on the wall for cleaning; the lifting and sliding cleaning mechanism can perform vertical and comprehensive cleaning of the wall.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0057] This invention relates to a gravity-assisted diaphragm wall cleaning device for cleaning diaphragm walls. The device adjusts the center of gravity of the guide support mechanism 3 via a center-of-gravity adjustment mechanism 4, fixing the bottom of the guide support mechanism 3 and then tilting its top towards the diaphragm wall compartment wall, thus fixing it to the compartment wall. This allows the cleaning mechanism 1, mounted on the guide support mechanism 3, to press against the wall surface with positive pressure. The lifting mechanism 2 adjusts the lifting and sliding of the cleaning mechanism 1 to clean the compartment wall.

[0058] A gravity-assisted, wall-mounted cleaning device, such as Figures 1-10As shown, the system includes a guide support mechanism 3, a lifting mechanism 2, a cleaning mechanism 1, and a center of gravity adjustment mechanism 4. The guide support mechanism 3 is equipped with a guide rail 33 along its axial direction. One end of the guide support mechanism 3 can be fixed to the compartment base. The guide support mechanism 3 supports the lifting mechanism 2 and the cleaning mechanism 1, providing guidance for the lifting mechanism 2 to move up and down. The lifting mechanism 2 is mounted on the guide support mechanism 3 in conjunction with the guide rail 33, allowing it to move up and down. The cleaning mechanism 1 is mounted on the lifting mechanism 2 and is used to clean the compartment wall. The center of gravity adjustment mechanism 4 is located on the upper part of the guide support mechanism 3 and is used to adjust the center of gravity of the guide support mechanism 3 so that the center of gravity of the guide support mechanism 3, which is connected to the guide support mechanism 3 as a whole, is located within the space formed by the guide support mechanism 3 and the wall. Under the action of gravity, the top of the guide support mechanism 3 is tilted and fixed to the compartment wall. After the top of the guide support mechanism 3 is fixed to the wall, the cleaning mechanism 1 has sufficient pressure on the wall for effective cleaning. The lifting mechanism 2 can drive the cleaning mechanism 1 to move up and down to achieve vertical and comprehensive cleaning of the wall.

[0059] like Figures 1-3 As shown, one end of the center of gravity adjustment mechanism 4 is hinged to the top of the guide support mechanism 3, and the other end is used to rotate around the hinge to adjust the center of gravity of the guide support mechanism 3 before being fixed to the partition wall. The center of gravity of this cleaning device is adjusted by rotation, which is simple and efficient.

[0060] More specifically, such as Figures 1-3 and Figure 7 As shown, the center of gravity adjustment mechanism 4 includes a swing arm 42 hinged to the top of the guide support mechanism 3 and a swing arm tail cone 44 located at the end of the swing arm 42 away from the guide support mechanism 3. The swing arm tail cone 44 has a conical structure. Preferably, the center of gravity adjustment mechanism 4 also includes a rotating beam 41 hinged to the top of the guide support mechanism 3 and a counterweight 43 located on the swing arm 42. The counterweight 43 preferably consists of multiple counterweight crossbars located at the end of the swing arm 42 away from the guide support mechanism 3. The two swing arms 42 are fixedly connected to the two ends of the rotating beam 41.

[0061] All components of this invention meet the actual assembly requirements for cleaning, and parameters such as size and length can be adjusted to meet the actual requirements for cleaning walls.

[0062] In addition, the guide support mechanism 3 may also be provided with a first drive device for driving the swing arm 42 to rotate around the hinge. The first drive device is preferably a motor. The motor is vertically mounted on the guide support mechanism 3. The output end of the motor is provided with transmission teeth. The end face of the rotating crossbar or the side of one end of the swing arm 42 is provided with end face teeth that can mesh with the transmission teeth. That is, the end face teeth mesh with the transmission teeth on the side of the output end of the motor. The center of gravity of the entire cleaning device is adjusted by driving the rotating crossbar to rotate through the motor. This is simple and convenient.

[0063] like Figures 1-3 and Figure 5As shown, the lifting mechanism 2 includes a mounting frame 21, a vertical slider 22 fixed on the mounting frame 21 and sliding in cooperation with the guide rail 33, and a second drive device for driving the mounting frame 21 to move up and down; the mounting frame 21 is used to longitudinally slide and connect the cleaning mechanism 1. The second drive device can be an external device, such as using a winch as the second drive device to pull the lifting mechanism to move up and down; preferably, the mounting frame 21 is provided with a diagonal brace 25 and a vertical extension section 24 located at the bottom of the mounting frame 21 near the vertical slider 22; the two ends of the diagonal brace 25 are respectively connected to the extension section 24 and the side of the mounting frame 21 away from the vertical slider 22. In one specific embodiment, the mounting frame 21 is formed by connecting four horizontal support rods 211, four vertical support rods 212, and four longitudinal support rods 213 to form a three-dimensional rectangular frame. The two horizontal support rods 211 near the guide support mechanism 3 are provided with sliders at their ends. The two vertical support rods 212 near the guide support mechanism 3 extend downward to form the aforementioned extension sections 24. The bottom ends of the two extension sections 24 are connected to the horizontal support rods 211 with vertical sliders 22 at both ends. The bottom end of the extension section 24 is connected to the longitudinal support rod 213 located at the bottom of the rectangular frame by a rod-shaped diagonal brace 25. The diagonal brace 25 is connected to the end of the longitudinal support rod 213 away from the vertical slider 22.

[0064] like Figures 1-4 As shown, the cleaning mechanism 1 includes a sliding fastener 11 for sliding connection with the mounting bracket 21, a third driving device for driving the sliding fastener 11 to slide, and a cleaning assembly fixed to the sliding fastener 11 for brushing and / or rinsing the wall surface.

[0065] The third drive device can drive the cleaning mechanism 1 to slide longitudinally on the mounting frame 21, so that the cleaning mechanism 1 is always close to the compartment wall, adapting to the compartment wall with poor flatness and achieving effective pressure for cleaning.

[0066] In some embodiments, the third driving device includes a telescopic hydraulic cylinder or pneumatic cylinder that is mounted on the mounting bracket 21 and whose telescopic end is connected to the cleaning mechanism 1.

[0067] In other embodiments, the third drive device is an elastic telescopic assembly with its two ends connected to the mounting bracket 21 near the guide support mechanism 3 and the cleaning mechanism 1, respectively, for elastically supporting the cleaning mechanism 1 against the compartment wall.

[0068] like Figure 4 As shown, in some embodiments, the cleaning assembly includes a cleaning component base 12, a brushing component 13 fixed to the cleaning component base 12 for scrubbing the compartment wall, and a rinsing component 14 laterally slidably connected to the cleaning component base 12 for rinsing the compartment wall. Further, the rinsing component 14 includes a multi-hole water jet nozzle that sprays water downwards at an angle to one side of the compartment wall; the brushing component 13 includes a wire brush laterally disposed on the cleaning component base 12.

[0069] The lifting mechanism 2, by sliding the wire brush, can scrub the walls of the compartment, effectively removing larger deposits such as mud and pebbles. A multi-hole water jet nozzle can be used to spray high-pressure water onto the walls, effectively removing smaller deposits such as mud and sand remaining in the grooves. This cleaning device can be equipped with either the scrubbing component 13 or the rinsing component 14 for wall cleaning, or both can be installed simultaneously for dual cleaning operations, further improving the cleaning effect.

[0070] like Figure 5 As shown, in some embodiments, a longitudinal groove 23 is formed between the two longitudinal support rods 213 on both sides of the mounting bracket 21; the sliding fastener 11 is a plate-like structure, and longitudinal sliders 111 are provided on both sides of the sliding fastener 11, which can be embedded in the longitudinal groove 23 and slide along the axial direction of the longitudinal groove 23. The longitudinal support rods 213 can limit the sliding fastener 11 in the vertical direction, and the vertical support rods 212 located on both sides of the sliding fastener 11 can limit the sliding fastener 11 in the lateral direction, so that the sliding fastener 11 can only slide longitudinally.

[0071] like Figure 4 As shown, in some other embodiments, the bottom end of the cleaning component base 12 is provided with a transverse groove 15; the rinsing component 14 is slidably disposed in the transverse groove 15 along the axial direction of the transverse groove 15, and the rinsing component 14 slides laterally on the cleaning component base 12 to spray water, thereby rinsing the wall surface covered by the cleaning component base 12.

[0072] like Figure 6 As shown, the guide support mechanism 3 includes a guide ladder beam 30 with a guide slide rail 33, a fixed bottom cone 34 fixed at both ends of the guide ladder beam 30, and a swing arm base 35 for connecting the center of gravity adjustment mechanism 4. The fixed bottom cone 34 has a cone-shaped structure.

[0073] Some embodiments, such as Figure 6 and Figure 8 As shown, the guide ladder beam 30 includes two opposing columns 31, which are fixedly connected by multiple connecting beams 32 to form a ladder-like structure. The guide slide rail 33 is arranged on the same side of the two columns 31 along the axial direction of the columns 31. The swing arm base 35 is located at the top of the two columns 31. Preferably, the swing arm base 35 is provided with a lifting hole for lifting the columns 31. The guide slide rail 33 includes an L-shaped slide rail, one side of which is fixedly connected to the column 31. The vertical slider 22 includes a U-shaped structure that fits into the other side of the L-shaped slide rail. That is, the vertical sliders 22 on both sides of the mounting frame 21 fit into the L-shaped slide rail on the two columns 31, so that the mounting frame 21 can only slide vertically.

[0074] like Figure 6As shown, the guide support mechanism 3 is equipped with a dual-axis tilt sensor 36 for detecting the tilt angle of the guide support mechanism 3. The tilt sensor 36 can detect the verticality of the guide support mechanism 3, i.e., the angle with the vertical direction of space, facilitating the adjustment of the center of gravity of the guide support mechanism 3 by the center of gravity adjustment mechanism 4. It can be understood that based on the detection of the verticality of the guide support mechanism 3 by the tilt sensor 36, the maximum vertical tilt angle of the guide support mechanism 3 can be controlled. For support safety, using the length of the swing arm 42 and the maximum permissible vertical tilt angle of the guide support mechanism 3, the maximum distance between the guide support mechanism 3 and the ground-connected wall is calculated using trigonometric functions. During construction, the distance between the guide support mechanism 3 and the ground-connected wall is controlled within the maximum distance, specifically, but not limited to, within 70% of the maximum distance.

[0075] The present invention also provides a method for cleaning diaphragm walls, using the above-mentioned gravity-assisted diaphragm wall cleaning device, the cleaning method comprising the following steps:

[0076] S1. The guide support mechanism 3 is vertically installed on the compartment base;

[0077] S2. Use the center of gravity adjustment mechanism 4 to adjust the center of gravity of the guide support mechanism 3 as a whole to be in the space between the guide support mechanism 3 and the partition wall to be cleaned, so that the top of the guide support mechanism 3 is tilted towards the partition wall and fixed on the partition wall under the action of gravity.

[0078] S3. Use cleaning mechanism 1 to clean the partition wall, and at the same time raise and lower sliding lifting mechanism 2 so that cleaning mechanism 1 can thoroughly clean the partition wall vertically.

[0079] In some embodiments, step S2 above includes using a first driving device to drive the swing arm 42 to rotate around the hinge towards the compartment wall, so that the center of gravity of the whole connected with the guide ladder beam 30 is shifted towards the compartment wall, the bottom end of the guide ladder beam 30 is fixed on the compartment base so that the top end is tilted towards the compartment wall, and the swing arm tail cone 44 on the swing arm 42 is inserted and fixed on the compartment wall.

[0080] In actual construction, lifting equipment can be used to hoist the guide ladder beam 30 and move it to one side of the compartment wall to be cleaned. Based on the tilt sensor 36 sensing the posture of the guide ladder beam 30, the swing arm 42 is rotated and adjusted to make the guide ladder beam 30 vertical and inserted and fixed on the compartment base. The swing arm 42 is rotated toward the side of the compartment wall to be cleaned, so that the center of gravity of the entire device connecting the guide ladder beam 30 is shifted toward the compartment wall, and the top of the guide ladder beam 30 moves toward the compartment wall, so that the swing arm tail cone 44 on the swing arm 42 is inserted and fixed on the compartment wall. The third drive device is used to make the brush 13 of the cleaning mechanism 1 abut against the compartment wall. The lifting mechanism 2 and the cleaning mechanism 1 are a whole. Under the action of gravity, the lifting mechanism 2 slides down along the guide rail 33 to clean the compartment wall. A winch can be used to connect the lifting mechanism 2 through the traction rope to control the lifting and sliding speed of the lifting mechanism 2.

[0081] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
