[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figures 1-7 As shown, a road cutting machine guidance device includes a cutting machine body 1. A handle 2 is fixedly connected to the left side of the cutting machine body 1 near the upper side. Two sliding rods 3 are fixedly connected to the right side of the cutting machine body 1 near the front and rear sides. Several linearly distributed limiting holes 4 are opened on the upper side of the two sliding rods 3. A guiding mechanism 5 is movably sleeved on the outer side of the sliding rods 3.
[0028] The guidance mechanism 5 includes a guide rod 51, with limit components 55 fixedly connected to the front and rear ends of the guide rod 51. A slide block 56 is movably sleeved on the outer side of the guide rod 51. A screw rod 52 is threadedly connected to the inner side wall of the slide block 56. A clamping plate 53 is rotatably connected to the lower side of the screw rod 52. The outer side of the clamping plate 53 is slidably connected to the inner side of the guide rod 51. A laser generator 54 is fixedly connected to the right side of the slide block 56.
[0029] It should be noted that the cutting machine body 1 is used to cut the road surface, creating gaps in the road surface. A column placed on the opposite side acts as a laser reflector. The laser emitted by the laser generator 54 is projected onto the column. Rotating the screw 52 can drive the clamping plate 53 to move up and down, causing the clamping plate 53 to work with the slide 56 to clamp the guide rod 51, thus fixing the position of the slide 56. This allows the laser generator 54 to adjust the relative position of its front and rear sides.
[0030] like Figure 3 , Figure 7 As shown, the limiting component 55 includes an upper retaining sleeve 551, a lower retaining sleeve 552 overlapping the lower side of the upper retaining sleeve 551, the inner sides of the upper retaining sleeve 551 and the lower retaining sleeve 552 being movably sleeved on the outer side of the slide rod 3, two slide sleeves 553 being movably sleeved on the front and rear sides of the upper retaining sleeve 551, and several rectangularly distributed locking blocks 554 being fixedly connected on the front and rear sides of the lower retaining sleeve 552, with the outer side of the locking block 554 being movably sleeved on the inner side of the slide sleeve 553.
[0031] It should be noted that the lower wall of the sliding sleeve 553 has a notch. When the notch is aligned with the locking block 554, the lower locking sleeve 552 can be pushed up directly from the bottom to make the upper locking sleeve 551 and the lower locking sleeve 552 close and cover the outside of the sliding rod 3. Then, the notch and the locking block 554 are misaligned, so that the lower locking sleeve 552 is fixed.
[0032] like Figure 4 As shown, two limiting rods 555 are fixedly connected to the inner side of the upper sleeve 551 at two positions close to the front and rear sides. The inner side of the sliding sleeve 553 is movably sleeved on the outer side of the limiting rods 555 through a circular plate. A first spring 556 is movably sleeved on the outer side of both limiting rods 555, and the first spring 556 is located on the left side of the circular plate.
[0033] It should be noted that the first spring 556 pushes the circular plate, so that the sliding sleeve 553 will not move on its own without human intervention.
[0034] like Figure 4 As shown, four rectangular inserts 557 are movably fitted on the inner front and rear sides of the upper sleeve 551 near the right side. Four rectangular second springs 558 are movably fitted on the inner front and rear sides of the upper sleeve 551 near the right side. The second springs 558 are located on the side of the inserts 557 near the slide bar 3. Buttons 559 are movably fitted on the inner sidewalls of the two slide sleeves 553 near the right side.
[0035] It should be noted that when each sliding sleeve 553 slides, one of the two inserts 557 on that side is inserted into the inner side wall of the sliding sleeve 553, so that the sliding sleeve 553 is fixed, while the lower notch of the sliding sleeve 553 and the locking block 554 are kept aligned or misaligned.
[0036] like Figure 5 As shown, the upper sleeve 551 has a limiting block 5510 movably sleeved on the inner side of its side wall near the left side, and the outer side of the limiting block 5510 is movably sleeved on the inner side of the limiting hole 4. The upper sleeve 551 has a third spring 5511 movably sleeved on the inner side of its side wall near the left side, and the third spring 5511 is located above the limiting block 5510.
[0037] It should be noted that the lower side of the limiting block 5510 is an isosceles triangle. The limiting block 5510 is inserted into the inner side of the limiting hole 4, so that the position of the upper sleeve 551 is fixed. At the same time, the shape of the limiting block 5510 does not affect the direct manual pushing of the limiting component 55.
[0038] like Figure 5 As shown, a baffle 5512 is slidably connected to the upper side of the guide rod 51 near the left side, and a limit plate 5513 is slidably connected to the lower side of the baffle 5512 near the left side. Two push rods 5514 are fixedly connected to the left side of the limit plate 5513, which are symmetrically distributed front and back. The outer side of the push rod 5514 is movably sleeved on the inner side of the upper sleeve 551. A fourth spring 5515 is movably installed on the right side of each of the two push rods 5514.
[0039] It should be noted that the upper side of the limiting block 5510 is provided with a round rod, the upper end of which is coplanar with the upper surface of the upper sleeve 551. Due to the restriction of the baffle 5512, the limiting block 5510 cannot move, causing the limiting component 55 to no longer move on the slide bar 3. Pushing the baffle 5512, the hole on the baffle 5512 is aligned with the round rod on the limiting block 5510, so that the limiting block 5510 can move.
[0040] like Figure 6As shown, the upper sleeve 551 has two limiting grooves 5516 distributed front and back on the upper side near the left side, and the lower protrusion of the baffle 5512 is slidably connected to the inner side of the limiting groove 5516.
[0041] It should be noted that the limiting groove 5516 is L-shaped, which allows the baffle 5512 to be pushed to the right and then pushed to the rear, thus fixing the baffle 5512 and preventing the fourth spring 5515 from driving the baffle 5512 to reset.
[0042] The working principle of this utility model is as follows: First, relying on the column placed opposite as a laser reflector, the laser emitted by the laser generator 54 is projected onto the column. Rotating the screw 52 can drive the clamping plate 53 to move up and down, causing the clamping plate 53 to cooperate with the slide 56 to clamp the guide rod 51, thus fixing the position of the slide 56. This allows the laser generator 54 to adjust the relative position of its front and rear sides. The lower side of the limiting block 5510 is an isosceles triangle. The limiting block 5510 is inserted into the inner side of the limiting hole 4, thus fixing the position of the upper sleeve 551. At the same time, the shape of the limiting block 5510 does not affect the direct manual pushing of the limiting component 55. The upper side of 10 is provided with a round rod, the upper end of which is coplanar with the upper surface of the upper sleeve 551. Due to the restriction of the baffle 5512, the limiting block 5510 cannot move, causing the limiting component 55 to no longer move on the slide rod 3. Pushing the baffle 5512, the hole on the baffle 5512 is aligned with the round rod on the limiting block 5510, allowing the limiting block 5510 to move. By adjusting the screw 52, the position of the front and rear sides of the laser generator 54 is adjusted, and the limiting block 5510 is inserted into the limiting hole 4 at different positions, thereby adjusting the position of the upper and lower sides of the laser generator 54, so that the laser emitted by the laser generator 54 is projected onto the preset laser reflection point. On the laser beam, the cutting machine body 1 maintains the laser point on the laser reflection column when cutting the road surface, thus achieving the purpose of cutting a straight line on the road surface. This eliminates the need for manual marking, reducing the workload of operators. Finally, the lower wall of the sliding sleeve 553 has a notch. When the notch is aligned with the locking block 554, the lower locking sleeve 552 can be pushed up from below, causing the upper locking sleeve 551 and the lower locking sleeve 552 to close and cover the outside of the sliding rod 3. Then, the notch and the locking block 554 are misaligned, causing the lower locking sleeve 552 to be fixed. The first spring 556 pushes the circular plate, so that the sliding sleeve 553 will not move on its own without the influence of manual operation. Each sliding sleeve 55 3. During sliding, one of the two inserts 557 on this side is inserted into the inner side wall of the sliding sleeve 553, so that the sliding sleeve 553 is fixed. At the same time, the lower notch of the sliding sleeve 553 and the locking block 554 are aligned or misaligned. By fixing the upper locking sleeve 551 and the lower locking sleeve 552 with the sliding sleeve 553, the guide rod 51 is installed on the sliding rod 3. Pushing the sliding sleeve 553 causes the locking block 554 to align with the notch on the lower wall of the sliding sleeve 553, so that the upper locking sleeve 551 and the lower locking sleeve 552 can be separated from each other, so that the guide rod 51 can be quickly removed from the sliding rod 3. The installation is convenient, the disassembly is simple, and the maintenance of the device is convenient.
