Description

Technical Field

[0001] This application relates to the field of surveying instrument technology, and in particular to an RTK instrument with a painting function. Background Technology

[0002] In fields such as building construction, road construction, and land planning, point setting is a fundamental and crucial task. Traditional RTK instruments are mainly used to acquire high-precision geographic location information to complete point setting tasks. However, in practice, after the positioning work is completed, manual spray painting marking is still required. This manual spray painting method has many drawbacks: on the one hand, manual spray painting marking is slow, which seriously affects the efficiency of point setting; on the other hand, manual spray painting is very prone to errors, resulting in inaccurate marking positions, which seriously affects the accuracy of subsequent construction or planning work.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this application is to provide an RTK instrument with a painting function to solve or alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] This application provides an RTK instrument with a painting function, the instrument comprising:

[0007] The RTK host is also connected to an antenna. The RTK host receives location information in real time through the antenna and processes it to obtain positioning data.

[0008] The RTK host is fixed to the top of the centering rod;

[0009] The painting mechanism is located at the bottom of the centering rod. After the RTK host completes the positioning, it sends a painting signal to the painting mechanism, and the painting mechanism performs painting at the positioning point.

[0035] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0036] According to specific embodiments of this application, such as Figure 1-2 As shown, this application provides an RTK instrument with a painting function, the instrument including:

[0037] RTK host 1 is connected to antenna 2. RTK host 1 receives location information in real time through antenna 2 and processes it to obtain positioning data.

[0038] Centering rod 3, RTK host 1 is fixed on top of centering rod 3.

[0039] The painting mechanism 5 is located at the bottom of the centering rod 3. After the RTK host 1 completes the positioning, it sends a painting signal to the painting mechanism 5, and the painting mechanism 5 performs painting at the positioning point.

[0040] The painting mechanism 5 includes at least a painting frame 51, which is fixed to the bottom of the centering rod 3.

[0041] The paint spray frame 51 has a receiving cavity, and a paint can 55 is provided in the receiving cavity. In this embodiment, an openable side cover 54 is provided on one side of the receiving cavity of the paint spray frame 51. The side cover 54 can be fixed to the paint spray frame 51 by means of screws, quick-release buckles, etc.

[0042] The paint spraying frame 51 is also equipped with a paint spraying valve, which is located below the paint tank 55 and is connected to the outlet of the paint tank 55.

[0043] The bottom of the paint spraying frame 51 is also provided with a spray nozzle, which is connected to the paint spraying valve and is set towards the ground.

[0044] In this RTK instrument, after the RTK host 1 completes precise positioning, it transmits its positioning data to the painting mechanism 5, allowing the painting mechanism 5 to begin painting operations. At this time, the painting mechanism 5 controls the paint valve to open for a set time. The pigment tank 55 is a pressurized tank. After the air valve opens, the pigment in the pigment tank 55 enters the spray nozzle through the paint valve and is guided by the spray nozzle to spray onto the ground. The entire positioning and marking operation of this RTK instrument is carried out simultaneously, eliminating the need for additional manual painting operations. This not only greatly improves the efficiency of positioning and marking but also avoids errors caused by manual painting, significantly improving the positional accuracy of point painting and ensuring the precision of the construction operation.

[0045] The centering rod 3 is also equipped with a signal transmitting handle 4, which contains a signal transmitter. The signal transmitter is electrically connected to the RTK host 1 and is used to transmit a painting signal to the painting mechanism 5 after receiving the positioning data from the RTK host 1.

[0046] In this embodiment, a signal transmission switch is also provided on the signal transmission handle 4. The signal transmission switch is electrically connected to the signal transmitter. When a paint spraying signal needs to be sent, the operator presses the signal transmission switch to send a paint spraying signal to the paint spraying mechanism 5.

[0047] In other embodiments, a power switch can be installed on the signal transmitting handle 4. This power switch connects to the circuit of the painting mechanism 5. After the RTK host 1 completes precise positioning, the operator presses the power switch, energizing the circuit in the painting mechanism 5 and opening the paint valve to perform the painting operation. After the painting operation is completed, the power switch is released, de-energizing the circuit in the painting mechanism 5 and stopping the painting operation. The painting mechanism 5 also includes a servo motor, which is connected to the paint valve for controlling its opening and closing.

[0048] In this embodiment, the opening and closing of the paint spray valve is controlled by a servo motor, which enables more precise control of the spray valve and helps to improve the efficiency of the painting operation.

[0049] The painting mechanism 5 also includes a power supply 52 and a signal receiver 53. The signal receiver 53 is located between the power supply 52 and the servo motor. When the signal receiver 53 receives the painting signal from the signal transmitter, it powers the servo motor.

[0050] In this embodiment, the signal receiver 53 and the signal transmitter can transmit signals wirelessly via Bluetooth or a signal cable, etc., and there are no restrictions here.

[0051] When the signal receiver 53 receives the paint spraying signal from the signal transmitter, the signal receiver 53 controls the circuit between the power supply 52 and the servo motor to be energized for a set time. At this time, the servo motor starts to work and drives the paint spraying valve to open for a set time. After the paint spraying operation is completed, the circuit between the power supply 52 and the servo motor is de-energized and the paint spraying valve closes.

[0052] The paint spray valve includes a cam 59 and a cam cavity 510. The cam 59 is mounted on the output shaft of a servo motor and is driven to rotate by the servo motor. In this embodiment, the servo motor drives the cam 59 to rotate within the cam cavity 510.

[0053] The paint spray valve also includes a sealing ball 57 and a sealing channel 58. The top end of the sealing channel 58 is connected to the opening of the paint tank 55, and the bottom end of the sealing channel 58 is connected to the cam cavity 510.

[0054] The blocking ball 57 blocks in the blocking channel 58, the blocking channel 58 contacts the blocking ball 57 and the cam 59, and a spring 56 is provided between the blocking ball 57 and the top of the blocking channel 58.

[0055] In this embodiment, when painting is required, the servo motor controls the cam 59 to rotate, causing the sealing ball 57 to move downward under the force of the spring 56. The sealing ball 57 enters the cam cavity 510 from the sealing channel 58. At this time, the pigment paint in the pigment tank 55 is sprayed into the cam cavity 510 from the sealing channel 58 under pressure. When the painting operation is completed, the servo motor drives the cam 59 to reset, and the sealing ball 57 re-enters the sealing channel 58, thus sealing the sealing channel 58.

[0056] In this embodiment, the diameter of the blocking ball 57 is the same as the inner diameter of the blocking channel 58, so that the blocking ball 57 can block the blocking channel 58; one end of the spring 56 is fixed to the top of the blocking channel 58, and the other end of the spring 56 is fixed to the blocking ball 57, so as to ensure that there is always an effective connection between the spring 56 and the blocking ball 57, so that the blocking ball 57 is always subjected to the elastic force of the spring 56.

[0057] The spray nozzle includes multiple main spray nozzles 61, all of which are connected to the bottom of the cam cavity 510, and the main spray nozzles 61 have a set angle with the axis of the paint spray frame 51.

[0058] The spray nozzle also includes multiple secondary spray nozzles 62. Each main spray nozzle 61 is connected to a secondary spray nozzle 62, and the axis of the secondary spray nozzle 62 is parallel to the axis of the paint spraying frame 51.

[0059] In this embodiment, after the pigment paint enters the cam cavity 510, it first flows into the main spray hole 61. Since the main spray hole 61 and the axis of the paint spraying frame 51 are at a certain angle, the pigment paint in the main spray hole 61 is radiated outward. At the same time, a portion of the pigment paint in the main spray hole 61 enters the secondary spray hole 62, and the pigment paint in the secondary spray hole 62 is sprayed vertically downward. Through the coordinated action of the main spray hole 61 and the secondary spray hole 62, the pigment paint can be sprayed more evenly onto the ground, resulting in a more uniform paint spraying effect.

[0060] The pigment can 55 is equipped with a quick-connect male connector, and the paint spray frame 51 is equipped with a quick-connect female connector in its receiving cavity. The quick-connect male connector and the quick-connect female connector are connected and installed.

[0061] In this embodiment, the quick-connect male connector on the paint can 55 is inserted into the quick-connect female connector on the paint spray frame 51, which facilitates the quick installation and removal of the paint can 55.

[0062] In other embodiments, a male thread may be provided at the outlet of the pigment tank 55, and a female thread may be provided in the receiving cavity of the paint frame 51. In this case, the male thread of the pigment tank 55 can be mated and installed in the female thread of the paint frame 51.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
