Embodiment Construction

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Such as Figure 1-4 As shown, an automatic control device for a caisson wall excavator includes a ring guide rail (100) and an excavation main frame (200), and the excavation main frame (200) moves on the ring guide rail (100). device and control unit; the locator includes an RFID transponder (102) and an identifier (202); the RFID transponder (102) is evenly distributed on the circular guide rail (100); the identifier (202) is installed on the mining host (200) On, the serial number of the RFID transponder (102) can be read; the control unit can analyze the information of the identifier (202) to determine the position of the mining host (200).

[0027] Preferably, the loop guide rail (100) includes a rail seat (101) and a protective cover (103), and the feature is that the RFID transponder (102) is installed on the guide rail seat (101) ...

Abstract

The invention relates to an automatic control device for an open caisson wall-sleeving excavator. The automatic control device is characterized by comprising a positioner and a control unit; the positioner comprises RFID transponders and a recognizer; the RFID transponders are uniformly distributed on a circumferential guide rail; the recognizer is installed on an excavation host and can read the number of the RFID transponders; and the control unit can analyze information of the recognizer and determine the position of the excavation host. Meanwhile, the invention provides an automatic control method of the open caisson wall-sleeving excavator. The working posture of the open caisson wall-sleeving excavator can be automatically controlled through the automatic control device, automatic even excavation and automatic over-excavation deviation rectifying in an open caisson of the excavator are achieved, the sinking precision of the open caisson can be improved, and the automatic control device and method have important significance on reducing interference of human factors.

Description

technical field [0001] The invention relates to an automatic control device and method for a caisson wall excavator, which are applied in the fields of underground structures and foundation engineering in civil engineering. Background technique [0002] Excavators are often used in caisson excavation. At present, the movement of the excavator is manually controlled, and it is difficult to achieve uniform and symmetrical excavation of the caisson, which may easily cause the caisson to deviate. At the same time, when the remote-controlled wall-mounted excavator is used, the depth of the caisson reaches more than 30 meters, and it is difficult for ground remote personnel to directly observe the state of the wall-mounted excavator. In order to achieve uniform and symmetrical excavation of caissons, reduce the interference of subjective factors of operators, and realize automatic uniform excavation and automatic over-excavation correction in caissons of excavators, it is of great...
