DETAILED DESCRIPTION

[0042] The present invention is further described in detail below through specific embodiments:

[0043] like Figure 1-Figure 9As shown, an embodiment of the present invention proposes a channel or river channel concrete lining plate cutting equipment under flowing water state, including an underwater cutting machine 1 and a truss 2, a traveling beam 3 and a telescopic frame structure 4; wherein, the truss 2 is arranged on the plane where the slope of the channel or river channel is located and arranged along the length direction of the plane; the traveling beam 3 is slidably connected to the truss 2 along the length direction of the truss 2 and arranged along the width direction of the plane; the telescopic frame structure 4 is slidably connected to the traveling beam 3 along the length direction of the traveling beam 3, and the underwater cutting machine 1 is rotatably connected to the telescopic frame structure 4 through a rotating structure 5, and the telescopic frame structure 4 is also used to drive the rotating structure 5 to drive the underwater cutting machine 1 to move in a direction perpendicular to the traveling beam 3.

[0044] The channel or river channel concrete lining plate cutting equipment under the flow state is mainly composed of an underwater cutting machine 1, a truss 2, a driving beam 3, a telescopic frame structure 4 and a rotating structure 5. The underwater cutting machine 1 can move along the length direction, width direction and perpendicular to the driving beam 3 on the slope of the channel or river channel, so that the underwater cutting machine 1 can meet the cutting work of the damaged concrete lining plate on the underwater slope, thereby improving the work efficiency and reducing the work difficulty of the staff.

[0045] It should be noted that the underwater cutting machine 1 uses an existing power device to make the traveling beam slide along the track beam of the truss; the power device is, for example, the cooperation of a winch and a steel wire traction rope.

[0046] In order to better understand the channel or river concrete lining plate cutting equipment under the flow state, the structure of the underwater cutting machine 1 and the like will be further optimized below.

[0047] First is the underwater cutting machine 1.

[0048] like Figure 3 and Figure 4 As shown, according to another embodiment of the present invention, a channel or river concrete lining plate cutting equipment under flowing water state, wherein the underwater cutting machine 1 includes a first drive 11 and a cutting blade 12, the first drive 11 is connected to the rotating structure 5; the cutting blade 12 is driven to rotate by the first drive 11.

[0049] Here, the first driver 11 drives the cutting blade 12 to rotate and cut the damaged concrete lining plate. Considering the waterproof problem, the first driver 11 generally adopts a hydraulic drive motor, which has a waterproof effect.

[0050] Specifically, a first connection mode between the first driver 11 and the cutting blade 12 is: the cutting blade 12 can be directly connected to the output shaft of the first driver 11, and the first driver 11 directly drives the cutting blade 12 to rotate to cut the damaged concrete lining plate.

[0051] The second connection mode between the first driver 11 and the cutting blade 12 is: a bracket located on one side is connected to the outer wall of the first driver 11, the cutting blade 12 is rotatably connected to the bracket through a rotating shaft, and the rotating shaft is connected to the output shaft of the first driver 11 through a transmission structure. In this embodiment, the transmission structure includes two pulleys 13 and a transmission belt 14 connected between the two pulleys 13, one of the pulleys 13 is connected to the output shaft of the first driver 11, and the other pulley 13 is connected to the rotating shaft. When the first driver 11 is started, the first driver 11 drives the pulley 13 connected thereto to rotate, and then transmits the power through the transmission belt 14, the other pulley 13 and the rotating shaft in turn to drive the cutting blade 12 to rotate to cut the damaged concrete lining plate.

[0052] Among them, the second connection method between the first driver 11 and the cutting blade 12 is the preferred method. Compared with the first connection method, this design can require the diameter of the cutting blade 12 to be relatively small, so as to reduce the probability of the cutting blade 12 breaking during the cutting process, which is conducive to the cutting blade 12 cutting through the concrete lining plate and better meeting the use requirements.

[0053] When the underwater cutting machine 1 cuts the damaged area of ​​the concrete lining plate under the flowing water state, the traveling beam 3 is controlled to slide along the truss 2, driving the cutting blade 12 to move to the damaged area of ​​the concrete lining plate, and the telescopic device 44 controls the cutting blade 12 to move down to the damaged area of ​​the concrete lining plate. The cutting blade 12 cuts the middle area of ​​the damaged area of ​​the concrete lining plate under the cooperation of the first driver 11, the second driver 51 and the third driver 310, and the cutting depth during cutting exceeds 10 mm of the thickness of the concrete lining plate in the damaged area of ​​the concrete lining plate. After completing the transverse cutting, the second driver 51 controls the cutting blade 12 to rotate 90 degrees to complete the longitudinal cutting of the cutting line in the middle area. The second driver 51 then repeats the rotation of 90 degrees twice in sequence, so that the cutting line of the cutting blade 12 is a closed loop, and the middle cutting of the damaged area of ​​the concrete lining plate can be completed, and the concrete panel to be recycled is formed by cutting. After the concrete panel to be recycled is recycled, a backfill groove B is formed in the damaged area of ​​the concrete lining plate.

[0054] Among them, each side of the backfill groove B formed by cutting needs to accurately cut the overlap area of ​​the new and old geomembranes, so that the subsequent new geomembrane has a reasonable overlap length. It is necessary to accurately cut each side of the backfill groove B; that is, reserve 3 to 5 mm without cutting through the lining plate and geomembrane, and use a crushing structure and a cleaning shovel to damage and remove the concrete in this area. In order to make this process go smoothly and effectively, such as Figure 5-Figure 8As shown, the outer wall of the first driver 11 is detachably connected to a crushing structure 15 located at the rear side of the cutting blade 12, wherein the crushing structure 15 includes a wedge plate 151, which is located behind the cutting blade 12 and arranged in the same plane, and the wedge plate 151 has a gradual crushing portion whose outer edge thickness gradually increases toward the middle, the starting end thickness of the gradual crushing portion is less than the thickness of the cutting blade 12, and the end thickness of the gradual crushing portion is greater than the width of the cutting seam formed by the cutting blade 12.

[0055] In this embodiment, the structure of the gradual crushing part is designed to facilitate the insertion of the wedge plate 151 into the cutting seam formed by the cutting blade 12, and to generate extrusion in the cutting seam to crush the concrete lining plate. Specifically, the traveling beam 3 controls the cutting blade 12 to perform multiple strip cuttings along the 150mm wide area of ​​the concrete lining plate around the edge of the backfill groove B to form a cutting seam; a single cutting forms a strip cutting strip, the cutting width of the strip cutting strip is 25mm, and the vertical distance between the bottom of the strip cutting strip and the bottom of the concrete lining plate is 5mm, forming a backfill groove C; the gradual crushing part of the wedge plate 151 is embedded in the cutting seam to generate extrusion to crush the concrete lining plate.

[0056] Specifically, a connecting plate is fixedly connected to the outer wall of the first driver 11, and the top of the wedge plate 151 is fixedly connected to the connecting plate via a connecting strip 153. In addition, two reinforcing blocks 152 located on different sides of the wedge plate 151 are connected between the connecting strip 153 and the wedge plate 151 to ensure that the wedge plate 151 has sufficient connection stability.

[0057] like Figure 5-Figure 8 As shown, in order to clean the broken concrete in the 150mm area around the backfill groove B, the outer wall of the first driver 11 is detachably connected with a cleaning structure 16 located at the rear side of the cutting blade 12. After the backfill groove B is accurately cut, the cleaning structure 16 moves with the underwater cutting machine 1 to clean the broken concrete.

[0058] Specifically, the cleaning structure 16 includes a cleaning shovel 161, which is located on one side behind the cutting blade 12 and is hinged with a connecting rod 162 fixedly connected to the outer wall of the first driver 11. The cleaning shovel 161 and the outer wall of the first driver 11 are also hingedly connected with a telescopic adjuster 163 for driving the cleaning shovel 161 to rotate;

[0059] In this embodiment, the two ends of the telescopic adjuster 163 are respectively connected to the cleaning shovel 161 and the outer wall of the first driver 11 by hinge connection. The telescopic adjuster 163 can be a hydraulic telescopic rod. The positions where the telescopic adjuster 163 and the connecting rod 162 are connected to the outer wall of the first driver 11 are all connected to the connecting plate. The telescopic adjuster 163 extends to control the cleaning shovel 161 to descend, so that the shovel mouth of the cleaning shovel 161 moves toward the side close to the cutting blade 12, and the shovel mouth of the cleaning shovel 161 faces the broken concrete. The cleaning shovel 161 is in working state. The cleaning shovel 161 moves with the underwater cutting machine 1 to clean the broken concrete and scrape off the 5mm thick concrete at the bottom of the concrete lining plate, exposing the original geomembrane at the local part of the backfill groove C. The traveling beam 3 controls the cleaning shovel 161 to clean the surface of the concrete lining plate in the 150mm wide area around the edge of the backfill groove C; when the cleaning shovel 161 completes the operation, the telescopic adjuster 163 retracts to control the cleaning shovel 161 to rise and return to its original position, so that the shovel mouth of the cleaning shovel 161 is away from the slope, so as to achieve the purpose of not affecting the cutting work of the cutting blade 12.

[0060] It should be noted that during the cutting process of the middle area of ​​the slope repair of the channel or river channel under the flowing water state, the crushing structure 15 and the cleaning structure 16 may not be installed on the underwater cutting machine 1 .

[0061] The second is the running beam 3.

[0062] like Fig. 9 As shown, according to another embodiment of the present invention, a channel or river concrete lining plate cutting equipment under flowing water state, wherein the traveling beam 3 has a guide slide 36 which is conducted along its length direction, and the side wall of the guide slide 36 is connected with a disassembly and assembly notch arranged along its movement path, and a rack 37 is arranged at the bottom of the guide slide 36 along its length direction, and the rack 37 is meshed with a traveling gear 38 located in the guide slide 36, and the traveling gear 38 is connected to a third driver 310 which is located outside the traveling beam 3 and fixedly connected to the telescopic frame structure 4 through a connecting shaft which freely passes through the disassembly and assembly notch.

[0063] When it is necessary to move the underwater cutting machine 1 along the length direction of the traveling beam 3 for cutting, the third driver 310 is started to rotate the traveling gear 38, and the traveling gear 38 and the third driver 310 are moved along the length direction of the guide slide 36 through the cooperation of the rack 37. The guide slide 36 drives the traveling gear 38, thereby driving the telescopic frame structure 4 to move along the length direction of the guide slide 36, that is, to move along the length direction of the traveling beam 3. The telescopic frame structure 4 drives the underwater cutting machine 1 to move along the length direction of the traveling beam 3 for cutting through the rotating structure 5.

[0064] The driving beam 3 specifically includes a top plate 31, a bottom plate 32, and two vertical plates 33 connected between the top plate 31 and the bottom plate 32. The two vertical plates 33 are connected to a "U"-shaped plate 41 on the separated sides. One end of the horizontal section of the "U"-shaped plate 41 is connected to the corresponding vertical plate 33 and its vertical section is arranged toward the bottom plate 32. Both ends of the bottom plate 32 facing the top plate 31 are connected to side plates 35. The two vertical plates 33, the two "U"-shaped plates 41, the bottom plate 32 and the two side plates 35 are surrounded to form two parallel and spaced arrangements. The gap formed between each "U"-shaped plate 41 and the corresponding side plate 35 is the corresponding disassembly gap; the two guide slides 36 are arranged with a rack 37, and the gears are meshed with the gears located in the corresponding guide slides 36, one of which is the above-mentioned traveling gear 38, and the other gear is the guide gear 39 and is rotatably connected to the telescopic frame structure 4 through a connecting rod passing through the corresponding disassembly gap, so as to ensure that the underwater cutting machine 1 can stably move along the length direction of the traveling beam 3 to cut. Among them, the guide slide 36 is connected along the length direction of the traveling beam 3, so that the guide gear 39 or the traveling gear 38 can be quickly removed from the corresponding guide slide 36; the third driver 310 can be a power device such as a hydraulic drive motor.

[0065] Next is the telescopic frame structure 4.

[0066] like Fig. 9 As shown, according to another embodiment of the present invention, a channel or river concrete lining plate cutting equipment under flowing water state, wherein the telescopic frame structure 4 includes a connecting seat and an adjusting plate 43, the connecting seat is slidably connected to the traveling beam 3 along the length direction of the traveling beam 3, the adjusting plate 43 is movably connected to the bottom of the connecting seat through a plurality of telescopic devices 44, and the rotating structure 5 is connected to the adjusting plate 43.

[0067] In this embodiment, the connecting seat includes an "L"-shaped plate 34 and horizontal plates 42 connected on both sides of the "L"-shaped plate 34. The "L"-shaped plate 34 is slidably covered on the bottom side of the traveling beam 3. There are two telescopes 44 and one is connected between each horizontal plate 42 and the adjustment plate 43. The above-mentioned third driver 310 is fixedly connected to one of the horizontal plates 42 and the output shaft of the third driver 310 freely passes through this horizontal plate 42. The above-mentioned connecting rod connected to the guide gear 39 is connected to the inner wall of the "L"-shaped plate 34.

[0068] Among them, both of the telescopic devices 44 can be hydraulic telescopic rods; the two telescopic devices 44 are operated to perform telescopic adjustment, driving the adjustment plate 43 to move away from the traveling beam 3, thereby driving the underwater cutting machine 1 to move away from the traveling beam 3 through the rotating structure 5, so that the rotating cutting blade 12 is extended into the damaged concrete lining plate, and at the same time, the underwater cutting machine 1 moves along the length or width direction of the plane where the slope is located to cut the damaged concrete lining plate.

[0069] Finally, there is the rotating structure 5.

[0070] like Fig. 9 As shown, according to another embodiment of the present invention, a channel or river concrete lining plate cutting equipment under flowing water state, wherein the rotating structure 5 includes a second driver 51, a driving gear 52 and a transmission gear 53, the second driver 51 is installed on the adjustment plate 43 through a mounting bracket, the driving gear 52 is driven to rotate by the second driver 51, the transmission gear 53 is meshed with the driving gear 52 and is coaxially connected with a mounting plate 54, and the underwater cutting machine 1 is connected to the mounting plate 54.

[0071] When the second driver 51 is running, the driving gear 52 rotates to drive the transmission gear 53 to rotate, and the mounting plate 54 rotates with the transmission gear 53 to drive the underwater cutting machine 1 to rotate, so that the cutting direction of the cutting blade 12 can be changed according to the demand. After the backfill groove B is accurately cut, the cleaning shovel 161 rotates counterclockwise under the drive of the rotating structure 5, and the broken concrete around the geomembrane overlap area can be cleaned.

[0072] In this embodiment, the second driver 51 may be a hydraulic drive motor, and the second driver 51 may be connected to the adjustment plate 43 through a seat plate, the driving gear 52 is located between the "L"-shaped plate 34 and the adjustment plate 43, and the adjustment plate 43 is located between the driving gear 52 and the mounting plate 54, so as to be arranged reasonably. The mounting plate 54 is fixedly connected to the base of the first driver 11 through a plurality of fixing bolts.

[0073] It should be noted that the first driver 11, the second driver 51, the third driver 310, the telescopic device 44, the telescopic regulator 163 and the power device can all be controlled to start and stop by an existing automatic controller or automatic control system.

[0074] The cutting device is specifically used as follows:

[0075] First, the automatic controller or automatic control system can be used to control the first driver 11, the second driver 51, the third driver 310, the telescopic device 44 and the power device to start and stop according to the demand, so as to drive the cutting blade 12 to cut the damaged concrete lining plate of the slope, and form a grid-shaped cutting line (such as Figure 3 , Figure 4 as well as Fig.10 ), forming a concrete panel to be recycled, and after the concrete panel to be recycled is recycled, a backfill groove B is formed in the damaged area of ​​the concrete lining plate;

[0076] Thirdly, the automatic controller or automatic control system controls the first driver 11, the second driver 51, the third driver 310, the retractor 44 and the power device to start and stop according to the demand to perform multiple strip cuttings on the concrete lining board in the 150mm wide area around the edge of the backfill groove B to form a cutting seam; a single cutting forms a strip cutting strip, the cutting width of the strip cutting strip is 25mm, and the vertical distance between the bottom of the strip cutting strip and the bottom of the concrete lining board is 5mm, forming a backfill groove C;

[0077] Then, the crushing structure 15 and the cleaning structure 16 are assembled on the underwater cutting machine 1, and finally the underwater cutting machine 1 is moved underwater. The first driver 11, the second driver 51, the third driver 310, the telescopic device 44, the telescopic regulator 163 and the power device are controlled to start and stop according to the demand through the automatic controller or the automatic control system, so as to drive the cutting blade 12 to perform precise cutting along each cutting seam, and in the process of precise cutting by the cutting blade 12, the wedge plate 151 is used to break the precisely cut concrete lining plate to form crushed concrete (such as Figure 5 and Figure 6 ); then adjust the cleaning shovel 161 to the working state to clean the broken concrete through the cleaning shovel 161 (such as Figure 7 and Figure 8 ). The automatic controller or automatic control system can use existing technology to realize the motion control of corresponding components.

[0078] The slope of the channel or river in this scheme is the slope of the channel or river where the water is in a flowing state.

[0079] This solution first uses cutting to form backfill groove B, then uses strip cutting around backfill groove B and crushes it with a crushing structure, and then uses a sweeping shovel to remove concrete fragments in the surrounding area. Avoid cutting damage to the unrepaired slabs and ensure that the overlap of the new and old geomembranes around the repair area is basically clean and the pasting is effective.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
