Description

Technical Field

[0001] The invention relates to the technical field of slotting equipment, in particular to a slotting device for water conservancy project construction. Background Art

[0002] In water conservancy projects, the installation and layout of pipelines are crucial. Water conservancy projects need to open some square grooves for installing cable ducts on the surface of the constructed concrete buildings. The existing solution is to form a square groove by reciprocating cutting with a toothless saw blade.

[0003] For example, a grooving device for water conservancy engineering construction with announcement number CN213137321U relates to the field of water conservancy engineering. The grooving device for water conservancy engineering construction comprises an impact drill, a drill bit is fixedly installed at the bottom end of the impact drill, a support frame is fixedly sleeved on the outer surface of the impact drill, a walking mechanism is fixedly installed at the front end of the support frame, and the walking mechanism and the support frame are fixedly connected by a reset spring. The impact drill drives the drill bit to first open a hole on the concrete surface and then expands the single inner wall of the hole under the restriction of the guide rail to form a placement groove, which can achieve the effect of single-movement grooving and solve the problem of inconvenience in opening holes in the prior art.

[0004] Another example is a wall grooving device with announcement number CN219600011U, which includes a protective shell, which is rotatably connected to a first cross bar and a second cross bar, the axes of the first cross bar and the second cross bar are located on the same straight line, and the first cross bar is provided with a coupling mechanism for coupling with the second cross bar; the first cross bar is slidably connected to a first slotting wheel and a second slotting wheel, and an adjustment mechanism for adjusting the first slotting wheel and the second slotting wheel is provided in the protective shell, and the protective shell is provided with a driving member for driving the first cross bar to rotate, and the first slotting wheel and the second slotting wheel slot the wall at the same time, which is beneficial to improving the efficiency of slotting the wall.

[0005] Traditional grooving devices use a drill for impact or a cutting machine for cutting. When using a drill for cutting, the impact force generated is large, and the flying stones may easily injure nearby workers. The groove wall after grooving is also not smooth, which may easily damage the placed cables. When using a saw blade for cutting, it is necessary to open multiple parallel wire grooves, and then use tools to remove the excess wall. Not only is it difficult to adjust the size of the groove, but in the later process of removing the wall, the part adhered to the wall is thicker, and it is time-consuming and laborious to remove, resulting in poor use effect.

[0014] Preferably, a fixing sleeve is fixedly mounted on the inner wall of the protective outer cover, the fixing sleeve is arranged on the outer periphery of the telescopic cylinder, and a sliding hole is opened on the side wall of the fixing sleeve.

[0015] Preferably, a stop block is fixedly mounted on the upper end of the cutting outer cover, and a limit block is fixedly mounted on the inner wall of the cutting outer cover.

[0016] Preferably, sliding blocks are fixedly installed at both ends of the connecting cylinder close to one side of the telescopic cylinder, and the sliding blocks are slidably installed in the sliding holes.

[0017] Preferably, a water pipe is connected to one side of the sliding block, the water pipe is communicated with the connecting cylinder, and a spray head is installed at the lower end of the connecting cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. A cutting machine is arranged inside the cutting cover. Both cutting machines are tilted, and the cutters of the cutting machines are also tilted. After the cutting machine is turned on, the cutters rotate to bevel the wall. The beveled cutter forms a certain angle with the material to be cut, and the cutting force and cutting heat are relatively small, which can reduce the cutting pressure and improve the cutting quality and life of the cutting machine. The cutter of the cutting machine cuts the wall into two cutting lines, and then removes the cutting part through other sharp tools to open a suitable groove. The cutting machine bevels, and the deeper the wall cuts, the closer the distance between the two cutters is, that is, the cross-section of the wall after cutting is a trapezoid. Compared with the rectangular cross-section formed by traditional straight cutting, the waste material after cutting is less adhered to the wall and is easier to remove. The force on the wall is a straight line. Compared with traditional drill bits, the wall fracture surface produced by bevel cutting is also relatively neat, which is convenient for grooving on the side of the wall of water conservancy projects and the placement of workpieces.

[0019] 2. The first support rod stands on the ground, the baffle is against the wall, the second support rod is inclined and pressed between the ground and the baffle, the baffle is parallel to the wall, the bolt is pressed against the wall, the nut is rotated, and one end of the bolt can be away from the baffle, which is convenient for fitting to the uneven wall, and convenient for limiting and fixing the baffle. The mounting rod slides in the connecting sleeve, and the distance between the two baffles is adjustable, which is convenient for fixing the position of the two baffles according to the flatness of the wall, thereby increasing the adaptability of the device.

[0020] 3. During the movement of the outer shell, the mounting ears and the outer shell move along the inclined extrusion block, that is, the mounting ears, the outer shell and the cutting machine are pressed downward, which provides a driving force for the cutting depth of the cutting machine. The two mounting rods have the same structure, and the cutting machine has uniform force on both sides, which has a good cutting effect and further ensures the stability of the cutting tool. Multiple extrusion blocks are combined into an uneven surface. The thickness of the wall to be removed is different. When removing in the later stage, you can start from the thinner area and cut a deeper groove, which further reduces the pressure of later removal.

[0021] 4. During the extension and retraction process of the telescopic cylinder, the position of the fixed sleeve remains unchanged, and the sliding blocks connected to both sides of the cylinder body move up and down in the sliding hole, adaptively adjusting the height of the top plate. By setting the third elastic member, the third elastic member is in a compressed state in the initial state, which plays a certain role in boosting the downward pressure on the top plate.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 5 A grooving device for water conservancy project construction includes a supporting mechanism 1 and a mounting mechanism 2 installed on one side of the supporting mechanism 1. One end of the supporting mechanism 1 is close to the wall, and the lower end thereof is supported by the ground. A grooving mechanism 3 is installed on the mounting mechanism 2. The grooving mechanism 3 includes an outer shell 31. Mounting ears 32 are fixedly installed at both ends of the outer shell 31. The outer shell 31 is connected to the mounting mechanism 2 through the mounting ears 32, so that the outer shell 31 can be close to the wall.

[0026] Two cutting components 5 are arranged inside the slotting mechanism 3. The cutting component 5 includes a cutting cover 51. A cutting machine 52 is arranged inside the cutting cover 51. Both cutting machines 52 are arranged at an angle. The cutters of the cutting machines 52 are also arranged at an angle. After the cutting machines 52 are turned on, the cutters rotate to bevel the wall. The beveled cutters form a certain angle with the material to be cut. The cutting force and cutting heat are relatively small, which can reduce the cutting pressure and improve the cutting quality and life of the cutting machine 52.

[0027] A protective mechanism 4 is provided at the upper end of the slotting mechanism 3, and the protective mechanism 4 includes a protective outer cover 41 installed at the upper end of the outer shell 31. By providing the protective outer cover 41, the waste generated by cutting is blocked inside the protective outer cover 41 and will not splash everywhere, which has a certain protective effect.

[0028] The cutting cover 51 is provided with a first connecting piece 53 , a second connecting piece 54 is provided on a side of the cutting cover 51 away from the first connecting piece 53 , and a telescopic cylinder 42 is installed on the top wall of the protective cover 41 .

[0029] A connecting mechanism 6 is provided inside the slotting mechanism 3 , and the connecting mechanism 6 includes a connecting cylinder 61 fixedly installed at the lower end of the telescopic cylinder 42 .

[0030] The position of the telescopic cylinder 42 is fixed, and the output end of the telescopic cylinder 42 is fixedly connected to the connecting cylinder 61. Connecting blocks 65 are fixedly installed on both sides of the lower end of the connecting cylinder 61. The connecting blocks 65 are rotatably connected to the two first connecting members 53. When the telescopic cylinder 42 is extended, the connecting cylinder 61 moves downward, and the two cutting covers 51 move away from each other. The width and depth of the cutting can be increased, and a larger groove can be opened. Conversely, when the telescopic cylinder 42 is shortened, the width and depth of the cutting can be reduced, and a smaller groove can be opened to meet different needs.

[0031] A slide rail 37 is fixedly installed on the side wall of the outer shell 31, and a second elastic member 38 is installed in the slide rail 37. The second elastic member 38 has the same structure as the first elastic member 24, and both are elastic structures. The second connecting member 54 is slidably installed in the slide rail 37, and the two ends of the second elastic member 38 are respectively fixedly connected to the second connecting member 54 and the inner wall of the slide rail 37. When the telescopic cylinder 42 is extended or shortened, the connecting cylinder 61 moves up and down, and the two cutting covers 51 rotate with the second connecting member 54 as the fulcrum. The inclination amplitude of the two cutters 52 changes and moves away from each other, thereby ensuring the stability of the cutters 52 when adjusting the angle.

[0032] The cutting machine 52 cuts at an angle. The deeper the wall is cut, the closer the distance between the two cutters is, that is, the cross-section of the wall after cutting is a trapezoid. Compared with the rectangular cross-section formed by traditional straight cutting, the waste after cutting is less adhered to the wall and is easier to remove. The force on the wall is a straight line. Compared with traditional drill bits, the wall fracture surface produced by the oblique cutting is also relatively neat, which is convenient for grooving the side of the wall of water conservancy projects and placing workpieces.

[0033] Example 2: Please refer to Figure 2-Figure 5The support mechanism 1 includes a baffle 11, a first support rod 13 is fixedly installed at the lower end of the baffle 11, the first support rod 13 stands on the ground, the baffle 11 is against the wall, a slide groove 14 is provided on the baffle 11, and a second support rod 15 is installed on one side of the baffle 11, one end of the second support rod 15 is slidably installed in the slide groove 14, and a movable head is provided at one end of the second support rod 15, which slides in the slide groove 14 to move the position of the second support rod 15 so that the second support rod 15 is tilted and pressed between the ground and the baffle 11, which is convenient for further fixing the baffle 11, and bolt top blocks 12 are threadedly installed on the upper and lower sides of the baffle 11, and the bolt top block 12 includes a bolt and a nut. The baffle 11 is parallel to the wall, the bolt is pressed against the wall, and the nut is rotated, so that one end of the bolt can be away from the baffle 11, which is convenient for fitting to the uneven wall and facilitating the limiting and fixing of the baffle 11.

[0034] A connecting sleeve 16 is fixedly installed on the inner wall of the baffle 11, and an avoidance groove 17 is opened on the connecting sleeve 16. The mounting mechanism 2 includes a mounting rod 21 slidably installed in the connecting sleeve 16, and the mounting rod 21 slides in the connecting sleeve 16. The distance between the two baffles 11 is adjustable, which is convenient for fixing the positions of the two baffles 11 according to the flatness of the wall, thereby increasing the adaptability of the device. The mounting rod 21 is used to connect the two baffles 11, and the slotting mechanism 3 is arranged on the mounting rod 21. After the baffle 11 is fixed, the slotting mechanism 3 can be limited and fixed. After the cutting machine 52 is turned on, the tool of the cutting machine 52 can cut the wall, and the position of the outer shell 31 can be moved to cut the wall into two cutting lines, and then the cutting part can be scraped off by other sharp tools to open a suitable slot.

[0035] Example 3: Please refer to Figure 2-Figure 6 A plurality of equally spaced extrusion blocks 22 are rotatably installed on one side of the mounting rod 21. The extrusion block 22 is arranged at one end of the mounting rod 21 close to the wall. The height of the extrusion block 22 is less than the width of the avoidance groove 17. A clamping groove 33 is provided on the mounting ear 32. The clamping groove 33 is slidably connected with the mounting rod 21. Concave holes 34 are provided on both sides of the outer shell 31. A driving shaft 35 is provided on the inner wall of the concave hole 34. A driving wheel 36 is installed on the driving shaft 35. After the cutting machine 52 is turned on, the tool of the cutting machine 52 can cut the wall. The driving shaft 35 drives the driving wheel 36 to rotate, so as to drive the outer shell 31 and the cutting machine 52 to walk on the wall and make a linear motion, which plays a driving and assisting role for manual self-propelled movement, and saves manpower to a great extent.

[0036] During the movement of the outer shell 31, the snap-in groove 33 of the mounting ear 32 slides along the mounting rod 21. When the mounting ear 32 moves to the position of the extrusion block 22, the mounting ear 32 and the outer shell 31 move along the inclined extrusion block 22, that is, the mounting ear 32, the outer shell 31, and the cutter 52 are pressed downward, providing a driving force for the deep cutting of the cutter 52. The two mounting rods 21 have the same structure, and the depth force on both sides of the cutter 52 is uniform, so the cutting effect is good, which further ensures the stability of the cutting tool.

[0037] An embedded groove 23 is provided on the rotating rod, and a first elastic member 24 is jointly arranged between the extrusion block 22 and the embedded groove 23. The first elastic member 24 is a member made of any elastic structure such as a spring, a metal sheet, etc. In the initial state, the first elastic member 24 is in an expanded state, and one end of the extrusion block 22 is higher than the mounting rod 21. After the extrusion block 22 is forced to squeeze the first elastic member 24, it can fit in the embedded groove 23, and the first elastic member 24 has a relatively small elasticity and can withstand a heavier force without deformation. When the outer shell 31 encounters a hard material that cannot be cut by the cutting machine 52 during movement, the mounting ear 32 is blocked by the extrusion block 22 and cannot continue to move forward. At this time, the extrusion block 22 squeezes the first elastic member 24, thereby reducing the inclination angle of the extrusion block 22, avoiding the forward movement of the outer shell 31, and providing buffering and protection for the device. When the mounting ear 32 passes over the extrusion block 22, the extrusion block 22 is reset under the action of the first elastic member 24, so as to facilitate the restoration of the secondary use of the device.

[0038] A plurality of extrusion blocks 22 are combined together to form an uneven surface, and the paths of the mounting ears 32 and the outer shell 31 passing over the extrusion blocks 22 are also uneven. Therefore, the bottom surface of the trough body after cutting by the cutting machine 52 is wavy. Therefore, the thickness of the wall to be removed is different. When removing in the later stage, you can start from the thinner area and cut a deeper trough body, which further reduces the pressure of later removal.

[0039] Example 4: Please refer to Figure 2-Figure 8 A limit block 56 is fixedly installed on the inner wall of the cutting cover 51. When the two cutting machines 52 approach each other to the limit, the two limit blocks 56 fit together, which limits the minimum angle between the cutting machines 52 and prevents the knives of the two cutting machines 52 from colliding with each other.

[0040] A stop block 55 is fixedly installed on the upper end of the cutting cover 51, and sliding blocks 62 are fixedly installed on both ends of the connecting cylinder 61 close to the telescopic cylinder 42. A third elastic member 64 is provided at the lower end of the sliding block 62, and a top plate 67 is fixedly installed at the lower end of the third elastic member 64. The third elastic member 64 is provided on the outer periphery of the fixed sleeve 43, and the top plate 67 is overlapped and installed on the upper end of the limit block 56.

[0041] During the process of adjusting the angle of the cutting machine 52, the top plate 67 always applies pressure on the upper end of the stop block 55, thereby ensuring the stability of the cutting machine 52 during the process of adjusting the angle.

[0042] A fixed sleeve 43 is also fixedly mounted on the inner wall of the protective outer cover 41 . The fixed sleeve 43 is arranged on the outer periphery of the telescopic cylinder 42 . A sliding hole 44 is opened on the side wall of the fixed sleeve 43 . The sliding block 62 is slidably mounted in the sliding hole 44 .

[0043] During the extension and retraction process of the telescopic cylinder 42, the position of the fixed sleeve 43 remains unchanged, and the sliding blocks 62 connected to both sides of the cylinder body 61 move up and down in the sliding hole 44, adaptively adjusting the height of the top plate 67. By setting the third elastic member 64, the third elastic member 64 is in a compressed state in the initial state, which plays a certain boosting role in the downward pressure on the top plate 67.

[0044] A water pipe 63 is connected to one side of the sliding block 62. One end of the water pipe 63 is connected to the connecting cylinder 61, and the other end is connected to a water pump. The water pump is placed in water. A nozzle 66 is installed at the lower end of the connecting cylinder 61. After the water pump is turned on, water is introduced into the water pipe 63 and the connecting cylinder 61. The water is sprayed out from the nozzle 66 and splashed on the contact surface between the cutting machine 52 and the wall, further reducing the heat and pressure generated during the cutting process on the cutting machine 52, and also reducing dust, with good use effect.
