Description

Technical Field

[0001] The utility model belongs to the field of dam concrete construction equipment. Background Art

[0002] A large amount of roller compacted concrete is used on the dam. After rolling and leveling, surface cutting will be carried out according to actual needs. The cutting depth is 50 - 10 cm, and the cutting work is carried out when the concrete is not completely cured but already does not prevent personnel from walking. The existing cutting equipment is a cutting machine dedicated to cutting concrete. The concrete is cut by a rotating cutting wheel, and there are the following problems: First, to avoid damage to the cutting wheel when encountering high-hard stones and causing equipment failures, and also for safety considerations, to avoid fragments from injuring workers when the cutting wheel is damaged, the cutting machine usually cuts the concrete at a relatively low moving speed, resulting in low cutting efficiency; Second, during the cutting process, a large number of stones in the concrete are cut, generating a large amount of stone powder, and the high-speed rotating cutting wheel will also raise the stone powder, resulting in a relatively poor construction environment and being unfavorable to the physical health of workers. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a self-made equipment for cutting dam roller compacted concrete. The utility model has the advantages of relatively high cutting efficiency, good safety and a relatively good construction environment.

[0004] The technical solution of the utility model: A self-made equipment for cutting dam roller compacted concrete includes a handheld rammer. A cutting module is provided at the output end of the rammer. The cutting module includes an adapter plate screwed to the rammer. A cutting plate is provided at the bottom of the adapter plate, and a tooth structure is provided at the bottom of the cutting plate.

[0005] In the self-made equipment for cutting dam roller compacted concrete described above, the upper end of the cutting plate is detachably connected to the adapter plate, and one of the corners at the lower end of the cutting plate is provided with a rounded corner.

[0006] In the self-made equipment for cutting dam roller compacted concrete described above, a pressing plate is provided on one side of the cutting plate, and a mounting plate welded to the adapter plate is provided on the other side of the cutting plate. At least two bolts are provided on the mounting plate. The bolts pass through the mounting plate and the cutting plate and then connect to the pressing plate.

[0007] In the self-made equipment for cutting dam roller compacted concrete described above, a reinforcing rib is provided between the mounting plate and the adapter plate.

[0008] In the self-made equipment for cutting dam roller compacted concrete described above, the cutting plate is in clearance fit with the bolts, and the upper end of the cutting plate abuts against the adapter plate.

[0009] In the self-made equipment for cutting dam roller compacted concrete described above, multiple horizontal through grooves are provided on both sides of the cutting plate, and all the through grooves are located below the pressing plate and the mounting plate.

[0010] In the aforementioned self-made equipment for cutting roller compacted concrete of the dam, the cross-sectional shape of the through groove is a right triangle, with one of the right-angled sides of the right triangle on the bottom surface of the through groove and the hypotenuse of the right triangle on the inclined surface of the through groove.

[0011] Compared with the prior art, the utility model improves the existing rammer. A cutting module is arranged on the rammer. The rammer drives the cutting plate on the cutting module to generate vertical vibration, and at the same time, the self-weight of the rammer is used to cut the concrete. The cutting efficiency is relatively high, and the structural strength of the cutting module is large. During operation, it will not cause fracture damage. Even if it breaks, due to the low movement speed, it will not injure workers, and the safety is good. Since the cutting plate only vibrates up and down to squeeze the stones in the concrete, the stones are squeezed into small pieces and do not form stone powder. Even if a small amount of stone powder is generated, due to the low movement speed of the cutting plate, it is difficult to raise the stone powder, and the construction environment is relatively good. In summary, the utility model has the advantages of relatively high cutting efficiency, good safety and good construction environment.

[0012] In addition, through further structural improvement, by setting a fillet on the cutting plate, it is convenient for the rammer to move forward along the cutting direction, making the utility model relatively convenient to use; by setting a tooth structure at the bottom of the cutting plate, the contact area between the cutting plate and the dried concrete surface layer can be reduced, making it easier to break the concrete and further improving the cutting efficiency; by setting through grooves on both sides of the cutting plate, the cut debris can enter the through grooves and be taken out of the cut seam as the cutting plate rises, playing a role in chip removal, which can also increase the cutting efficiency.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as the basis for limiting the present utility model.

[0021] Embodiment 1. A self-made device for cutting roller-compacted concrete of a dam, which includes a hand-held rammer. A cutting module is provided at the output end of the rammer, and the cutting module is made of overall steel.

[0022] As Figures 1 to 3 shown, the cutting module includes an adapter plate 1 that is screwed to the rammer. A cutting plate 2 is provided at the bottom of the adapter plate 1. The two sides at the bottom of the cutting plate 2 are appropriately ground and narrowed to form cutting edges, and the width of the cutting edges is 2 - 3 mm. The cutting plate 2 is welded to the adapter plate 1. A tooth structure 9 is provided at the bottom of the cutting plate 2. The tooth structure 9 is composed of a plurality of triangular protrusions. A fillet 3 is provided at one of the corners at the lower end of the cutting plate 2.

[0023] The hand-held rammer is a common device of the construction team and can be directly purchased. Assembling the cutting module to the rammer obtains the self-made concrete cutting device, and it will not damage the overall structure of the rammer. After removing the cutting module, the rammer still has its original ramming function, and the improvement cost is extremely low. During use, the worker holds the rammer and uses the rammer to drive the cutting plate 2 to vibrate up and down continuously to cut the concrete. After cutting to a certain depth, move the rammer forward and continue to cut the concrete. During use, keep the fillet 3 in the forward direction of the rammer, and the fillet 3 can make it more convenient for the rammer to move forward. During the cutting operation, although the concrete is not completely solidified, the surface layer has solidified well and is relatively firm. By providing the tooth structure 9 at the bottom of the cutting plate 2, the contact area between the cutting plate 2 and the concrete can be reduced, and better cutting efficiency can be achieved.

[0024] Embodiment 2. Different from Embodiment 1, as Figures 4 to 6 shown, a pressing plate 4 is provided on one side of the cutting plate 2. An installation plate 5 that is welded to the adapter plate 1 is provided on the other side of the cutting plate 2. Three reinforcing ribs 7 are provided between the installation plate 5 and the adapter plate 1. Three bolts 6 are provided on the installation plate 5. The bolts 6 pass through the installation plate 5 and the cutting plate 2 and then connect the pressing plate 4. The cutting plate 2 is in clearance fit with the bolts 6, and the upper end of the cutting plate 2 abuts against the adapter plate 1.

[0025] A plurality of horizontal and vertically arranged through grooves 8 are provided on both sides of the cutting plate 2. The cross-sectional shape of the through grooves 8 is a right triangle, and one of the right-angled sides of the right triangle is on the bottom surface of the through groove 8, and the hypotenuse of the right triangle is on the inclined surface of the through groove 8. All the through grooves 8 are located below the pressing plate 4 and the installation plate 5.

[0026] The thickness of the cutting plate 2 is 10 mm, the groove depth of the through groove 8 is 3 mm, and the cutting plate 2 is heat-treated and hardened.

[0027] Different from Embodiment 1, 1), in Embodiment 2, the cutting plate 2 is detachably connected to the adapter plate. When the cutting plate becomes dull or deformed, the cutting plate 2 can be directly replaced, and the adapter plate 1 can still be used, reducing the use cost. 2), by welding the mounting plate 5 at the bottom of the adapter plate 1 and arranging the reinforcing rib 7 on the mounting plate 5, and clamping the cutting plate 2 on the mounting plate 5 by using the pressing plate 4, the vertical state of the cutting plate 2 can be firmly maintained, making the cutting plate 2 not easily bend and deform, and improving the service life. 3), by arranging the through grooves 8 on both sides of the cutting plate 2, while not increasing the downward cutting resistance of the cutting plate 2, the cut debris can enter the through grooves 8 and be carried out of the cut with the rising of the cutting plate 2, playing a role in chip removal, which can increase the cutting efficiency.
