Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to an integrated mast integrating a rotary sensor and a GNSS antenna and an excavator. Background Art

[0002] In the precision work of an excavator, in order to accurately control the attitude of the excavator, reduce the consumption of materials and fuel, and reduce the number of auxiliary personnel, it is necessary to use a 3D guidance assistance system for assistance. The 3D guidance assistance system can display in real time data such as the attitude of the excavator and the three-dimensional coordinates of the tip of the excavator bucket. The operator can guide the operation through the graphical information fed back by the 3D guidance assistance system, so as to achieve the effect of improving the construction quality.

[0003] The main components of the 3D guidance assistance system include a display, a controller, sensors, a GNSS antenna, a radio antenna, etc. Among them, the GNSS antenna is a signal receiving antenna of the Global Navigation Satellite System (GNSS). In order to improve the signal reception effect, it needs to be installed outside the excavator housing; the sensors generally include an inclination sensor, a pitch sensor, a rotary sensor, etc. Among them, the rotary sensor is required to be installed at the center of rotation of the excavator and above to monitor the rotation state of the slewing body.

[0004] In the prior art, the rotary sensor is usually arranged inside the excavator housing. However, since there are many types and large quantities of hardware to be installed inside the excavator housing, and the rotary sensor needs to be installed with a separate mounting base, there are situations where the rotary sensor is inconvenient to arrange, is easily interfered or collided by other devices; at the same time, the cable of the rotary sensor is usually exposed inside the excavator housing, the wiring is complex, there are safety hazards, and the inspection and maintenance are more difficult. Summary of the Utility Model

[0005] Aiming at the problems in the prior art that the rotary sensor is arranged inside the excavator housing, the rotary sensor is inconvenient to arrange, is easily interfered or collided by other devices, the cable wiring of the rotary sensor is complex, there are safety hazards, and the inspection and maintenance are more difficult, the utility model provides an integrated mast integrating a rotary sensor and a GNSS antenna and an excavator, which does not need to set a mounting base to arrange the rotary sensor separately, and avoids the rotary sensor being interfered or collided by other devices; it can reduce the exposure of the cable outside the integrated mast, and make the cable layout of the rotary sensor and the GNSS antenna safer, more reasonable and more beautiful.

[0006] The present utility model provides an integrated mast integrating a rotary sensor and a GNSS antenna, which comprises a vertically arranged mast tube body. The top end of the mast tube body is connected to the rotary sensor. A connecting block is arranged on the side surface of the mast tube body, and the connecting block is connected to a vertically arranged connecting rod. The top end of the connecting rod is connected to the GNSS antenna. A wire passing hole is arranged on the side surface of the mast tube body, and the cables of the GNSS antenna and the rotary sensor pass through the wire passing hole and enter the interior of the mast tube body. A mast base is arranged at the bottom of the mast tube body.

[0007] Further, the mast tube body is a hollow stainless steel tube.

[0008] Further, an installation groove is arranged at the top end of the mast tube body, and the rotary sensor is connected to the mast tube body through the installation groove.

[0009] Further, a thread is arranged at the top end of the connecting rod, and the GNSS antenna is threadedly connected to the connecting rod.

[0010] Further, a rubber ring is arranged in the wire passing hole, which can protect the cable passing through the wire passing hole and prevent the cable from being scratched by the wire passing hole.

[0011] Further, a maintenance opening is arranged on the side surface of the mast tube body, which is convenient for maintaining the lines arranged inside the mast tube body.

[0012] Further, screw holes are arranged on the base, and bolts can be used to pass through the screw holes to fixedly connect the mast base to the surface to be connected.

[0013] In a second aspect, the present utility model provides an excavator equipped with the above integrated mast, which comprises a traveling device. A slewing body is rotatably connected above the traveling device. An excavator housing is arranged outside the slewing body, and the integrated mast is installed on the excavator housing.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the integrated mast integrating a rotary sensor and a GNSS antenna provided by the present utility model, the rotary sensor and the GNSS antenna are centrally arranged on the integrated mast. There is no need to set up an installation base to separately arrange the rotary sensor, and the rotary sensor does not need to be arranged inside the excavator, avoiding being interfered with or collided by other devices during use.

[0016] 2. The cables of the rotary sensor and the GNSS antenna pass through the wire passing hole and enter the interior of the mast tube body for centralized wiring. On the one hand, the process of separately wiring the rotary sensor can be saved, reducing the total workload of wiring. On the other hand, the exposure of the cables outside the integrated mast can be reduced, making the cable layout of the rotary sensor and the GNSS antenna safer, more reasonable and more beautiful.
