DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-4 As shown, a T-Probe measuring rod trolley for laser measurement and positioning includes a vehicle body 1 and a motion mechanism 2 arranged at the bottom 1 of the vehicle body, a cleaning mechanism 3 is arranged on one side of the vehicle body 1, and a spraying mechanism 4 is arranged on the other side, the top of the vehicle body 1 is connected to the surface of a T-Probe measuring rod 6 through a position adjustment mechanism 5, a measuring ball 7 is arranged at the bottom of the T-Probe measuring rod 6, and a reflector 8 is arranged on the top, and the reflector 8 cooperates with a T-Probe laser tracking head 9 arranged on the ground.

[0021] Preferably, the motion mechanism 2 is a crawler-type walking wheel mechanism, and its driving mechanism control end is wirelessly connected to the handheld remote control through the antenna 2.1. In this embodiment, the crawler-type walking wheel mechanism is a magnetic adsorption crawler wheel, which is characterized in that the robot is stably attached to the wall surface by adsorption of permanent magnets and magnetic conductive walls. The crawler surface of the robot is provided with multiple permanent magnets, and the front wheels are driven to rotate through the driving mechanism to drive the crawler to run. The electronic control unit of the driving mechanism is an ESP8266 single-chip microcomputer, which acts on the displacement control of the trolley.

[0022] Preferably, the cleaning mechanism 3 is a drum brush structure. In this embodiment, the drum brush is driven by a motor to rotate to remove dust attached to the surface of the measuring point area.

[0023] Preferably, the spraying mechanism 4 comprises an ink box 4.1, a discharge port of the ink box 4.1 is connected to one end of an electric powder feeding pump 4.2, and the other end of the electric powder feeding pump 4.2 is connected to a powder feeding pipe 4.3.

[0024] Preferably, the position adjustment mechanism 5 includes a plurality of servo motors 5.1 fixedly arranged on the top of the vehicle body 1, the output end of the servo motor 5.1 is fixedly connected to the lower end of the vertical screw 5.2, the surface of the vertical screw 5.2 is matched with the internal thread of the moving block 5.9, the top of the vertical screw 5.2 is rotationally connected to the bottom of the fixed block 5.3, the top of the moving block 5.9 is fixedly connected to the bottom of the vertical moving rod 5.4, the top of the vertical moving rod 5.4 is hinged to the bottom of the tilting rod 5.5, the top of the tilting rod 5.5 is hinged to the edge of the adjusting disk 5.6, the inside of the adjusting disk 5.6 is provided with a fixed T-Probe measuring rod 6, and a measuring hole 1.1 for passing the T-Probe measuring rod 6 is opened inside the vehicle body 1. In this embodiment, when the servo motor 5.1 is working, it can drive the vertical screw rod 5.2 to rotate. Since the surface of the vertical screw rod 5.2 cooperates with the internal thread of the moving block 5.9, the moving block 5.9 can be lifted vertically, thereby driving one side of the tilting rod 5.5 to move through the tilting rod 5.5. Here, it can be divided into the following two situations: 1. The reflector 8 corresponds exactly to the laser irradiated by the T-Probe laser tracking head 9: that is, when the T-Probe measuring rod 6 is controlled to move downward by the position adjustment mechanism 5 so that the measuring ball 7 contacts the surface of the measuring point area, the multiple servo motors 5.1 work together and rotate forward or reverse synchronously, so that the multiple moving blocks 5.9 can be synchronously lowered, and then the multiple vertical moving rods 5.4 can be synchronously lowered, and finally the tilt rod 5.5 and the adjustment disk 5.6 are synchronously lowered, thereby driving the T-Probe measuring rod 6 to move downward so that the measuring ball 7 contacts the surface of the measuring point area. At this time, the reflector 8 corresponds exactly to the laser irradiated by the T-Probe laser tracking head 9; and because the T-Probe measuring rod 6 is in a vertical state in the initial state, the vertical projection of the reflector 8 is the measuring point position where the measuring ball 7 is located.

[0025] 2. The lasers irradiated by the reflector 8 and the T-Probe laser tracking head 9 do not correspond: that is, when the inclination angle of the T-Probe measuring rod 6 is adjusted by the position adjustment mechanism 5, thereby changing the position of the reflector 8, a part of the servo motor 5.1 rotates forward by a certain angle, and another part of the servo motor 5.1 rotates reversely by a certain angle, thereby causing a part of the moving block 5.9 to descend, and another part of the moving block 5.9 to rise, thereby causing a part of the vertical moving rod 5.4 to descend, and another part of the vertical moving rod 5.4 to rise, and finally one side of the adjustment disk 5.6 descends, and the other side rises, and the adjustment disk 5.6 tilts, thereby adjusting the inclination angle of the T-Probe measuring rod. When the measuring ball 7 at the bottom of the T-Probe measuring rod 6 rubs against the ground and generates some displacement, resulting in a change in position. The inclination sensor arranged on the adjustment plate 5.6 can clearly display the inclination angle of the T-Probe measuring rod 6. When the length of the T-Probe measuring rod 6 is known (the length of the T-Probe measuring rod 6 is approximately equal to the distance between the reflector 8 and the measuring ball 7), the deviation between the vertical projection point of the reflector 8 and the measuring point position of the measuring ball 7 can be calculated (that is, under the premise of knowing the angle and hypotenuse of a right triangle, the length of one of the right-angled sides can be obtained), and then the measuring point position data can be corrected.

[0026] More preferably, the plurality of fixing blocks 5.3 are all fixedly connected to the bottom of the fixing plate 5.7, and the bottom of the fixing block 5.3 is fixedly connected to the outer shell of the servo motor 5.1 via a limiting rod 5.8.

[0027] More preferably, the surface of the vertical moving rod 5.4 is in sliding cooperation with the interior of the fixed block 5.3 and the interior of the fixed plate 5.7, and the interior of the moving block 5.9 is in sliding cooperation with the surface of the limiting rod 5.8.

[0028] More preferably, the adjustment disk 5.6 is also provided with an inclination sensor. By providing the inclination sensor, it is convenient to calculate the accurate position of the measuring ball 7 according to the measured distance and the inclination angle of the T-Probe measuring rod 6.

[0029] In addition, the present invention also discloses a method for using the T-Probe measuring rod trolley for laser measurement and positioning, which comprises the following steps: S1. Set up the T-Probe laser tracking head 9, remotely control the motion mechanism 2, move the vehicle body 1 to the measuring point area, start the cleaning mechanism 3 to clean the measuring point area, and set the vehicle body 1 to move forward until the measuring hole 1.1 of the vehicle body 1 faces the measuring point area; S2, control the T-Probe measuring rod 6 to move downward through the position adjustment mechanism 5, so that the measuring ball 7 contacts the surface of the measuring point area; if at this time the reflector 8 and the laser irradiated by the T-Probe laser tracking head 9 just correspond (in this case, since in the initial state, the T-Probe measuring rod 6 is in a vertical state, the vertical projection of the reflector 8 is the measuring point position where the measuring ball 7 is located), then execute step S4; if at this time the reflector 8 and the laser irradiated by the T-Probe laser tracking head 9 do not correspond, then execute step S3; S3, adjusting the tilt angle of the T-Probe measuring rod 6 through the position adjustment mechanism 5, thereby changing the position of the reflector 8, so that the laser irradiated by the T-Probe laser tracking head 9 just corresponds to the reflector 8; S4. The T-Probe laser tracking head 9 emits laser light and receives the laser light reflected by the reflector 8 to measure the position data of the measuring point. In this embodiment, the data obtained by the T-Probe laser tracking head 9 uses MicroPython as the data processing programming software.

[0030] S5. After the data is measured, the vehicle body 1 is set to move forward until the powder delivery pipe 4.3 is directly opposite to the measuring point, and the electric powder delivery pump 4.2 is started to mark the measuring point.

[0031] Furthermore, if the laser irradiated by the reflector 8 and the T-Probe laser tracking head 9 do not correspond at this time, step S3 is executed, and then in the process of executing step S4, by adjusting the inclination angle of the T-Probe measuring rod 6 fed back by the inclination sensor on the disk 5.6, and knowing the length of the T-Probe measuring rod 6, the deviation between the vertical projection point of the reflector 8 and the measuring point position where the measuring ball 7 is located can be calculated, and then the measuring point position data can be corrected; the corrected measuring point position data also facilitates the subsequent accurate marking process.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
