Embodiment Construction

[0030] figure 1 The demolition robot 1 is shown in more detail. An operator 2 (machine operator) walks beside the demolition robot 1 and performs wireless remote control of the demolition robot 1 via a remote control device 4 comprising a transmitter / receiver unit. A chassis comprising a carriage with a top carriage 6 and a bottom carriage 7 is indicated generally at 5 . The top bracket 6 is twistably mounted on the bottom bracket 7 to swing in a horizontal plane. The bottom bracket 7 is equipped with propulsion means comprising rails 8 . The supporting legs are indicated at 9 and operated by associated hydraulic cylinders, while the operable arm means indicated at 10 are supported on the top carriage 6 and can be operated by means of hydraulic cylinders. The cables are indicated with 12 and are intended to be connected to a fixed three-phase electrical network to provide the demolition robot 1 with electrical input power in the form of electrical energy. The fixed three-p...

Abstract

The invention relates to a demolition robot (1) comprising: a cable (12) intended to be connected to an electrical network for powering a motor (21); a pump (22) powered by an electric motor to generate a hydraulic flow for the consumer (13), where the motor (21) can be activated at different thermal load values (FT) according to the need of the current consumer (13) for hydraulic power; a control unit (24) arranged to receive information about thermal loads (FT) on the motor to determine partial thermal damage values (SL, SM, SH) on the motor under various thermal loads (FT). In order to minimize the risk of thermal damage to the motor, the control unit (24) is adapted to compare said partial thermal damage value (SL, SM, SH) with a standard partial thermal damage (A) and to limit the thermal load (FT) on the motor (21) to a maximum allowable thermal load value (PTmax) when the partial thermal damage value (SL, SM, SH) exceeds the standard partial thermal damage (A) by a predetermined value (A ').

Description

technical field [0001] The invention relates to a demolition robot in which an electric motor is installed and powers a load in the form of a hydraulic pump which, by means of a so-called power regulation, can supply the consumables of the demolition robot with variable hydraulic output power hydraulic flow. In the demolition device, control and monitoring functions are included in order to prevent the demolition robot from being used in a manner that could cause thermal damage to the electric motor of the demolition robot. Background technique [0002] The energy supply or input power for the demolition robot usually consists of electrical current, which is obtained from the conventional three-phase power distribution network at the site. The demolition robot is supplied with electrical energy via cables which are connected to suitable outlets in the electricity distribution network. The demolition robot has an electric motor and a three-phase device that provides input p...
