Description

Technical Field

[0001] This application relates to the technical field of grooving equipment, and in particular, to a grooving equipment. Background Art

[0002] Grooving equipment is a special mechanical equipment used for excavating deep and narrow grooves, and is widely used in fields such as urban construction, road construction, and subway construction. It mainly includes bucket-wheel grooving machines, rotary grooving machines, impact grooving machines, disc-type grooving equipment, etc.

[0003] Currently, the existing disc-type grooving equipment includes a front power device and a tail cutting device. The cutting device consists of a cutting disc and a power system. When in use, the front power device drives the tail cutting device to move forward, and then the power system drives the cutting disc to rotate to cut the ground to form a groove.

[0004] During the long-term use of the disc-type grooving equipment, the tooth blocks on the cutting disc will become dull, resulting in a decrease in cutting efficiency and the quality of the groove not meeting the standard. Especially when only a few tooth blocks are dull, replacing the entire cutting disc is too wasteful, and continuing to use it will affect the working effect. Utility Model Content

[0005] In order to improve the cutting efficiency when a few tooth blocks are dull, this application provides a grooving equipment.

[0006] This application provides a grooving equipment, adopting the following technical solution:

Detailed implementation mode

[0038] The following will further elaborate on this application in conjunction with the Figures 1-4 accompanying drawings.

[0039] The embodiment of this application discloses a grooving device. Refer to Figure 1 , the grooving device includes a power unit 1. The power unit 1 is of a vehicle body structure. One side of the tail end of the power unit 1 is hinged with a mounting bracket 11, and a saw blade 2 is rotatably connected to the mounting bracket 11. The power unit 1 is provided with a driving unit 3. The driving unit 3 includes a driving motor, and the driving motor is fixedly installed on the mounting bracket 11. The output shaft of the driving motor is detachably fixed to the saw blade 2. When in use, the driving motor is started to drive the saw blade 2 to rotate, and the ground is cut to form a groove.

[0040] The mounting bracket 11 is detachably fixed with a protective cover 7. The protective cover 7 is located above the saw blade 2 and covers the saw blade 2. One side side wall of the protective cover 7 is open. On the one hand, it is convenient to disassemble and install the saw blade 2. On the other hand, when the saw blade 2 cuts the ground, the soil lifted by the saw blade 2 falls on the inner wall of the protective cover 7 and then detaches through the open side of the protective cover 7.

[0041] The power unit 1 is also electrically connected to a hydraulic control system and sensors. During operation, the power unit 1 moves forward. At this time, the hydraulic system presses down the saw blade 2 for grooving. The sensors sense the speed, vehicle body attitude, etc. of the power unit 1 and transmit them to the power unit 1. Then the power unit 1 controls the hydraulic system to output downward pressure on the saw blade 2, so that the grooving depth of the saw blade 2 on the ground can be kept in a consistent state.

[0042] The saw blade 2 includes a disc body 21, a mounting strip 22 and saw teeth 23. The disc body 21 is of a disc-shaped structure, and the mounting strip 22 is of an annular structure. The mounting strip 22 is fixedly installed on the outer peripheral side of the disc body 21. The thickness of the mounting strip 22 is greater than the thickness of the disc body 21, and the distances between the two ends of the disc body 21 and the adjacent ends of the mounting strip 22 are equal.

[0043] Refer to Figure 1 And Figure 2, one end of the mounting strip 22 is formed with a mounting groove 222 extending axially. There are multiple mounting grooves 222 which are evenly spaced circumferentially, and the notches of adjacent mounting grooves 222 are located on opposite sides. The mounting strip 22 is provided with mounting blocks 4, and the mounting blocks 4 correspond to the mounting grooves 222 one by one. The mounting blocks 4 slide in the mounting grooves 222. The saw teeth 23 correspond to the mounting blocks 4 one by one. The saw teeth 23 are fixed on the mounting blocks 4 and protrude outside the mounting grooves 222.

[0044] A limiting block 41 is fixedly connected to the side wall of the mounting block 4. A limiting groove 221 is formed by communicating the side walls of the mounting groove 222, and the limiting groove 221 extends axially. The limiting block 41 slides in the limiting groove 221 to limit the mounting block 4 and reduce the possibility of the mounting block 4 disengaging from the mounting groove 222 in the direction away from the axis of the disk body 21.

[0045] See Figure 3 And Figure 4 , the mounting strip 22 is provided with a fixing member, and the fixing member includes a fixing bolt 5. The mounting strip 22 is formed with a threaded hole extending in a direction perpendicular to the axis of the disk body 21, and the threaded hole communicates with the mounting groove 222. The fixing bolt 5 is threadedly connected to the wall of the threaded hole. A sliding hole is formed on the side of the mounting block 4 facing away from the saw teeth 23, and the fixing bolt 5 is inserted into the sliding hole. When the mounting block 4 is installed and slides into the mounting groove 222, the fixing bolt 5 is threadedly connected through the threaded hole and then inserted into the sliding hole until the bolt head of the fixing bolt 5 abuts against the inner circumferential side wall of the mounting strip 22, so as to realize the connection and fixation between the mounting block 4 and the mounting strip 22.

[0046] A control hole is formed in the middle of the mounting block 4, and the extending direction of the control hole is parallel to the axis of the disk body 21. The mounting block 4 is provided with a control column 42, and the control column 42 passes through the control hole and is threadedly connected to the wall of the control hole. Both ends of the control column 42 protrude outside the mounting block 4. During use, by rotating the control column 42, the length of the control column 42 protruding outside the mounting block 4 is adjusted; when the mounting block 4 is installed, the end of the control column 42 abuts against the wall of the mounting groove 222. When the position adjustment of the mounting block 4 is completed, it is used to limit the position of the mounting block 4 so that there can be a staggered arrangement between adjacent saw teeth 23, improving the cutting effect of the saw disk 2 on the ground.

[0047] See Figure 2 And Figure 3 , the mounting strip 22 is formed with a card slot 223, and the card slot 223 extends in a direction perpendicular to the axis of the disk body 21 and communicates with the mounting groove 222. The mounting strip 22 is provided with a card block 6. The card block includes a block body and a clamping portion. There are two clamping portions which are respectively fixed on opposite sides of the block body. The clamping portions are clamped into the card slot 223, and there is friction between the clamping portions and the wall of the card slot 223, so that the card block 6 is preliminarily fixed after installation.

[0048] SeeFigure 2 With Figure 4 , on one side of the clamping block 6 close to the mounting block 4, an abutting surface 61 is formed obliquely. During installation, the clamping block 6 is snapped into the card slot 223 until the abutting surface 61 abuts against one side of the mounting block 4 close to the notch of the mounting groove 222. A fixing block is fixedly connected to the side wall of the clamping block 6, and a control bolt 63 is threadedly connected to the fixing block. The bolt head of the control bolt 63 protrudes axially out of the mounting groove 222 along the disk body 21, and the control bolt 63 is rotatably connected to the connecting block 62. A connecting groove 43 is formed in the mounting block 4. When the clamping block 6 is snapped into the card slot 223, the connecting block 62 is snapped into the connecting groove 43. The connecting groove 43 communicates with the sliding hole, and the connecting block 62 is formed with a plugging groove 621. When the clamping block 6 is installed, the control bolt 63 is rotated to adjust the position of the connecting block 62 so that the plugging groove 621 is aligned with the sliding hole, and then the fixing bolt 5 is rotated so that the fixing bolt 5 is threadedly connected to the groove wall of the plugging groove 621, further improving the installation stability of the clamping block 6.

[0049] The implementation principle of a grooving device according to an embodiment of the present application is as follows:

[0050] When replacing the passivation saw teeth 23, first reverse-rotate to remove the fixing bolt 5, then take out the clamping block 6, then slide the mounting block 4 out of the mounting groove 222, and then a new saw tooth 23 can be replaced. During replacement, the mounting block 4 is slid into the mounting groove 222, then the clamping block 6 is snapped into the card slot 223, then the control bolt 63 is rotated to adjust the position of the connecting block 62 so that the plugging groove 621 is aligned with the sliding hole, and finally the fixing bolt 5 is installed. At this time, the bolt head of the fixing bolt 5 abuts against the inner peripheral side wall of the mounting strip 22, and the screw part of the fixing bolt 5 is threadedly connected to the groove wall of the plugging groove 621.

[0051] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
