[0042] Embodiment 1

[0043] In order to solve the problem that the excavator operator cannot know in real time whether the current excavation is close to the safety distance, thereby easily causing the pipeline to be easily damaged by controlled excavation. As shown in Figures 1-4 A kind of excavator construction protects underground pipeline real-time early warning device is provided, including fixed structure 1 in the excavator with the small arm connected to shovel, telescopic structure 2 arranged on fixed structure 1, pipeline distance sensor 3 for real-time sensing the distance between ground and underground pipeline arranged on telescopic structure 2, and monitoring module 4 for real-time monitoring of the current shovel distance of shovel by telescopic structure 2 telescoping arranged on telescopic structure 2. The pipeline distance sensor 3 is electromagnetic inductor or / and ground penetrating radar and the like.

[0044] In practice, the device is fixed on the small arm connected with the bucket of the excavator through the fixed structure 1, and the telescopic structure 2 needs to be ensured to be in the appropriate position. After being fixed, when the excavator is excavating, the bucket excavates underground, at this time, the telescopic structure is in contact with the ground and is compressed, so that the pipeline distance sensor can sense the distance between the ground and the underground pipeline in real time, which is convenient for the operator to feedback the relative position of the excavator and the pipeline, thereby reducing the risk of misoperation. At the same time, the monitoring module accurately controls the excavation depth and range of the bucket, improves the precision and quality of construction, and enables the excavator operator to know in real time whether the current excavation is close to the safe distance, thereby avoiding the problem that the pipeline is easily damaged by controlled excavation. For example, the ground is an unexcavated ground A, the excavation depth is B, and the pipeline position is C. When the telescopic structure cooperates with A, the distance between the unexcavated ground and the underground pipeline is A minus C. When the telescopic structure cooperates with the B-depth ground, the distance between the currently excavated ground and the underground pipeline is A minus the sum of B and C. The specific method is determined according to the setting of the telescopic structure.

[0045] Embodiment 2

[0046] On the basis of embodiment 1, the telescopic structure 2 includes a sleeve rod 5 arranged on the fixed structure 1. Along the length direction of the sleeve rod 5, a cavity 6 is arranged on the sleeve rod 5, and a transparent partition plate 7 is arranged in the cavity 6 to divide the cavity 6 into a first cavity 9 and a second cavity 10. The first cavity 9 is sealed at one end of the fixed structure 1 and is open at the other end. The second cavity 10 is sealed at both ends. A return spring 11 is arranged on the sleeve rod in the first cavity 9 at one end of the fixed structure 1, and a telescopic rod 12 is connected to the return spring 11. The telescopic structure divides the cavity into the first cavity and the second cavity through the transparent partition plate, which is convenient for arranging the pipeline distance sensor and the monitoring module. When the telescopic rod is compressed under force, the pipeline distance sensor and the monitoring module will collect corresponding data according to the specific situation, which not only ensures that the distance between the pipeline distance sensor and the underground pipeline is accurately sensed, but also facilitates the monitoring module to accurately control the excavation depth and range of the bucket. Conversely, the reset can be operated once.

[0047] Embodiment 3

[0048] On the basis of embodiment 2, a transparent protective cover 13 is arranged on the telescopic rod 12 at the opposite end connected with the reset spring 11, and the pipeline distance sensor 3 is arranged on the telescopic rod 12 in the transparent protective cover; when the telescopic structure 2 is in the reset state, the distance between the pipeline distance sensor 3 and the pipeline is the distance between the bucket tooth and the pipeline when the bucket tooth and the ground are in the vertical state, and the pipeline distance sensor 3 on the telescopic rod 12 can be in contact with the ground when the bucket excavation process changes. The purpose of arranging the transparent protective cover is to prevent the pipeline distance sensor 3 from being impacted, and to limit the initial position of the pipeline distance sensor 3 on the telescopic structure, so that the telescopic structure can be in contact with the ground through the transparent protective cover at any time during the bucket excavation process, so that the pipeline distance sensor 3 can accurately identify the distance between the ground and the pipeline at any time during the movement of the telescopic structure.

[0049] Embodiment 4

[0050] On the basis of embodiment 3, the monitoring module 4 includes a plurality of infrared receivers 14 arranged at equal intervals along the length direction of the second cavity 10, and an infrared emitter 15 arranged on the telescopic rod 12 at one end of the reset spring 11, located on one side of the infrared receiver 14. Each infrared receiver 14 can present a corresponding depth at the end of the construction personnel. When the telescopic rod is compressed during the bucket operation, the information emitted by the infrared emitter on the telescopic rod will be received by the infrared receivers from bottom to top in turn, and the signal received by each height of the infrared receiver can be used to monitor the bucket distance in real time, so that the distance change between the bucket and the pipeline can be accurately obtained. Conversely, the telescopic rod is reset, and the next excavation monitoring can be performed. For example, the pipeline distance sensor 3 cooperates with the undug ground A to obtain the distance between the ground and the pipeline, and subtracts the safety distance. Since the small arm is moving, the pipeline distance sensor 3 will also be used, so that the nearest distance can be obtained in real time to obtain the most reliable safety impact, and the most reliable safety bucket distance of the bucket excavation can be obtained. The corresponding infrared receiver 14 can be corresponded to the corresponding infrared receiver 14, so that the construction personnel can directly observe whether the signal is received by the corresponding infrared receiver 14 during excavation; when the pipeline distance sensor 3 cooperates with the ground of the current excavation depth, the current distance between the ground and the pipeline can be sensed by the pipeline distance sensor 3, and the current bucket distance that can be excavated can be judged by the infrared receiver 14, so as to judge whether the bucket excavation is close to or reaches the safety bucket distance that needs to be maintained. If it is close, the operation can be slowed down, and if it reaches the safety bucket distance that needs to be maintained, the operation is stopped.

[0051] Embodiment 5

[0052] On the basis of embodiment 4, the first cavity 9 is a square cavity, and the first cavity is defined as a square cavity, which aims to prevent the telescopic rod from rotating, which may cause the signal emitted by the infrared emitter to be unable to be received by the infrared receiver, thereby affecting the monitoring problem. Of course, in practice, it is not excluded that other structures can also be used.

[0053] Embodiment 6

[0054] On the basis of embodiment 5, the telescopic structure 2 is located on both sides of the bucket and separated from the bucket, and the telescopic structure is located on both sides of the bucket and separated from the bucket, which facilitates the rotation of the bucket, and the telescopic structure does not rotate, and can be directly matched with the unexcavated ground, so as to quickly obtain the digging distance of the bucket, thereby facilitating rapid construction and improving construction efficiency.

[0055] Of course, in practice, the telescopic structure 2 located on both sides of the bucket can also be attached to the bucket, which is used to match the pipeline distance sensor 3 with the current excavated ground. Considering the possible poor matching effect, it is best to choose the implementation manner of the present embodiment.

[0056] Embodiment 6

[0057] On the basis of embodiment 5, the fixed structure 1 includes two clamps 16 clamped on the small arm, which is set according to the shape of the small arm structure, a protective pad 17 set on the inner side of the clamp 16 and a support rod 18 set on the clamp 16, and a bolt and a nut matched with the two clamps 16; the telescopic structure 2 is fixedly arranged on the support rod 18. By clamping the small arm with the two clamps and using the protective pad and the bolt and nut to fix, the stability of the fixed structure is ensured, and the displacement of the structure caused by vibration during excavation is reduced.
