[0044] Example 1

[0045] like Figures 1 to 3 As shown, this embodiment provides a grooving device for building cable troughs, including a grooving mechanism 1, the grooving mechanism 1 includes a plurality of cutting blades 101 and a driving device 102 for driving the cutting blades 101, the grooving device also includes a moving component 2, a positioning component 3, and a control panel 4, and a microcontroller for controlling the operation of the grooving device is installed in the control panel 4.

[0046] The moving component 2 includes a base 201 and a wheel set 202. The wheel set 202 is installed on the lower side of the base 201. The wheel set 202 includes a pair of driving wheels and a pair of driven wheels, which are used to move the base 201. An electric steering gear 203 is provided at the connection between the driven wheels and the base 201. The forward direction of the driven wheels can be adjusted by the electric steering gear 203, thereby changing the moving direction of the base 201.

[0047] The height of the base 201 is adjustable. In this embodiment, as shown in the figure, height telescopic rods 204 are provided at the connection between the driving wheel, the driven wheel and the base 201. At the same time, a spirit level 205 is provided on the base 201. The spirit level 205 and each height telescopic rod 204 are electrically connected to the control panel 4. After the leveling command is input through the control panel 4, the control panel 4 adjusts the extension of each height telescopic rod 204 according to the measurement data of the spirit level 205, so that the base 201 is leveled.

[0048] When the cutting blade 101 needs to be aligned with the height of the slotted position, the required lifting height can be input through the control panel 4, and then the control panel 4 simultaneously adjusts the extension amount of each height telescopic rod 204 to lift the base 201, and finally aligns the cutting blade 101 with the slotted position.

[0049] In this embodiment, the slotting mechanism 1 includes a protective cover 103 in addition to the cutting blade 101 and the driving device 102. Specifically, the cutting blade 101 is installed on the inner side of the protective cover 103, and the driving device 102 is fixedly installed on the outer side of the protective cover 103 and is dynamically connected to the cutting blade 101. The protective cover 103 is provided with an opening on the side facing the second wall for the cutting blade 101 to extend out. A portion of the cutting blade 101 extends out from the opening and can contact the second wall. When the cutting blade 101 is working, it can slot on the second wall.

[0050] In order to adjust the groove depth, the groove mechanism 1 is rotatably connected to the base 201, and a first adjuster 5 is provided at the connection. The first adjuster 5 is used to adjust the cutting depth of the cutting blade 101. Specifically, the first adjuster 5 includes a first rotating shaft 501, a horizontal telescopic rod 502, and an angle sensor. The two ends of the horizontal telescopic rod 502 are respectively rotatably connected to the protective cover 103 and the base 201, and can be telescoped in the horizontal plane to adjust the rotation angle of the groove mechanism 1. One side of the protective cover 103 is fixedly connected to the first rotating shaft 501, so that the groove mechanism 1 can rotate around the first rotating shaft 501, thereby making the cutting blade 101 close to or away from the second wall.

[0051] The angle sensor is installed at the first rotating shaft 501 and is used to measure the rotation angle of the slotting mechanism 1 relative to the initial position. The control panel 4 is electrically connected to the moving component 2, the positioning component 3, the horizontal telescopic rod 502 and the angle sensor.

[0052] When the first rotating shaft 501 rotates, as the rotation angle changes, the distance between the cutting blade 101 and the second wall also changes. Since the diameter and center trajectory of the cutting blade 101 are known, by measuring the rotation angle of the center of the cutting blade 101, the control panel 4 can calculate the change value ΔL of the distance between the cutting blade 101 and the second wall.

[0053] Since the slotting mechanism 1 is rotatably connected to the base 201, and the connection point is located at the edge of the protective cover 103, the rotating shaft at the connection needs to bear the weight of the entire slotting mechanism 1, which puts a relatively large burden on the structure of the connection. Figure 4 As shown, an arc-shaped slide rail 206 is provided on the upper surface of the base 201, and the circle of the arc-shaped slide rail 206 coincides with the axis of the first rotating shaft 501. At the same time, a support member 104 is fixedly provided at the bottom of the protective cover 103. The support member 104 slides in the arc-shaped slide rail 206, thereby supporting the slotting mechanism 1 and reducing the load at the connection. When the slotting mechanism 1 rotates, the support member 104 slides along the arc-shaped slide rail 206 and will not hinder the rotation of the slotting mechanism 1.

[0054] like Figure 2 , Figure 6 The positioning component 3 includes an X-axis positioning component 301 and a Y-axis positioning component 302. The X-axis positioning component 301 includes an optical distance sensor facing the first wall. Specifically, the sensor is an infrared distance sensor for measuring the distance L1 between the slotting device and the first wall. The Y-axis positioning component 302 includes an infrared distance sensor facing the second wall for measuring the distance L2 between the base 201 and the second wall. The first wall and the second wall are perpendicular to each other. At the same time, the directions of the X-axis positioning component 301 and the Y-axis positioning component 302 are also perpendicular. The change value of L1 is the moving distance of the base 201, and the value of L2 is the distance of the base 201 relative to the second wall.

[0055] In other embodiments, the optical distance sensor may also use other types of optical distance measuring devices such as a laser distance measuring sensor.

[0056] like Figure 5 When grooving, the grooving device moves parallel to the second wall, and L2 remains unchanged. According to the change value ΔL of the distance between the cutting blade 101 and the second wall and the distance L2 between the base 201 and the second wall, the depth of the cutting blade 101 cutting into the wall can be measured, which is the grooving depth.

[0057] The control panel 4 is also used to correct the moving direction of the driving wheel group 202. Specifically, when the grooving device moves parallel to the second wall, the control panel 4 fine-tunes the rotation angle of the driven wheel in real time according to the measurement data L2 of the Y-axis positioning component 302, so that the value of L2 remains unchanged at all times, thereby ensuring the uniformity of the grooving depth during the grooving process.

[0058] Through the above-mentioned settings, the construction cable trough grooving device provided in this embodiment can accurately locate the position of the grooving device without the need for manual holding, so that the opened cable trough remains straight and has a uniform depth, thereby improving the aesthetics of the cable trough and avoiding affecting the laying of pipelines. It can be used to replace manual excavation of horizontal cable troughs on the wall.

[0059] When using the above-mentioned slotting device to slot the second wall, the steps are as follows:

[0060] S1. Plan a slotting track on the slotting plane, and at least measure the distances L1 and L2 between the starting point and the end point of the slotting track and the first wall and the second wall;

[0061] S2, inputting the starting point and end point coordinates of the slotting track and the slotting depth through the control panel 4 of the slotting device;

[0062] S3, start the moving component 2 to move the slotting device to the starting position, calibrate the position of the slotting device through the X-axis positioning component 301 and the Y-axis positioning component 302, and adjust the height of the base 201 to align the cutting blade 101 with the planned slotting position;

[0063] S4, start the cutting assembly, use the horizontal telescopic rod 502 to adjust the slotting depth, and measure the slotting depth through the angle sensor;

[0064] S5. After reaching the preset grooving depth, the moving component 2 works to move the grooving device along the grooving track and grooving on the grooving plane. During the movement, the X-axis positioning component 301 and the Y-axis positioning component 302 continuously calibrate the position of the excavation device until the end position is reached, and then the grooving stops.

[0065] Example 2

[0066] This embodiment is further improved on the basis of embodiment 1. Specifically, Figure 7 , Figure 8 As shown, a crosshair fixing assembly 303 is provided on the base 201 , and the crosshair fixing assembly 303 can emit a visible optical mark toward the second wall surface, and the optical mark is used to mark the height of the cutting blade 101 .

[0067] Through this arrangement, the height of the cutting blade 101 can be adjusted more accurately before grooving, so that the grooving position is more accurate.

[0068] One to two cross-line fixed-point components 303 can be provided. If two are provided, they can be arranged in a vertical direction so that the center of the emitted cross-shaped light spot is located in the same horizontal plane as the upper edge and the lower edge of the cutting blade 101 respectively. By adjusting the height of the base 201 and aligning the cross-shaped light spot with the upper edge and the lower edge of the slotting track, the cutting blade 101 can be accurately aligned with the slotting track.

[0069] Example 3

[0070] This embodiment is further improved on the basis of embodiment 2. Specifically, Figure 8 As shown, a dust cover 105 is provided at the opening of the protective cover 103 to block dust generated by the slotting. The dust cover 105 can slide along the opening of the protective cover 103 to make the dust cover 105 close to or away from the second wall.

[0071] Furthermore, a spring can be provided at the sliding rail of the dust cover 105 and the protective cover 103, so that the dust cover 105 is pushed toward the second wall by the spring. When the groove is cut, the dust cover 105 can be as close to the wall as possible to reduce dust diffusion.

[0072] A vertical baffle is provided at one end of the dust cover 105 close to the second wall. When the dust cover 105 is close to the second wall, the baffle can abut against the second wall to prevent the dust cover 105 from being embedded in the wire trough when the wire trough is widened for the second time.

[0073] A cleaning brush 106 is also provided at the opening of the dust cover 105. The cleaning brush 106 is located on one side of the cutting blade 101 when it rotates into the dust cover 105. The cleaning end of the cleaning brush 106 is embedded in the gap between the cutting blades 101. When the cutting blade 101 rotates, the cleaning brush 106 can remove dust and debris carried by the cutting blade 101 to prevent the cutting blade 101 from bringing debris into the dust cover 105.

[0074] Example 4

[0075] This embodiment is further improved on the basis of Embodiment 3. Specifically, in a preferred embodiment of the present invention, the X-axis positioning component 301 and the Y-axis positioning component 302 each independently include two parallel optical distance sensors. In other embodiments, a larger number of optical distance sensors may also be included.

[0076] Through the above settings, when the values ​​measured by the two parallel optical distance sensors are the same, it means that the X-axis positioning component 301 and the first wall surface, and the Y-axis positioning component 302 and the second wall surface remain perpendicular, and the slotting device does not deviate.

[0077] Example 5

[0078] This embodiment is further improved on the basis of embodiment 4. Specifically, Fig. 9 As shown, in a preferred embodiment of the present invention, the X-axis positioning assembly 301 is also used to measure the distance L3 between the slotting device and the third wall. The third wall is parallel to the first wall. During the slotting process, L3 can be used to measure the distance between the slotting device and the third wall to avoid collision.

[0079] In addition, because the slotting device keeps moving in a direction parallel to the second wall surface, the sum of the values ​​of L1 and L3 is a fixed value. If this value changes, even if the value of L2 remains unchanged, it means that the moving direction is no longer parallel to the second wall surface. At this time, the moving direction of the driven wheel can be adjusted according to this value to make L1+L3 return to the initial value. Therefore, the moving direction can be corrected by the distance L3 to improve the moving accuracy.

[0080] In summary, the present invention utilizes the positioning component 3 to measure the distance between the grooving device and two vertical walls, thereby accurately locating the position of the grooving device without the need for manual holding, so that the opened cable trough remains straight and has a uniform depth, thereby improving the aesthetics of the cable trough and avoiding affecting the laying of pipelines.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
