Description

Technical Field

[0001] This utility model belongs to the technical field of bucket wheel stacker-reclaimers, specifically relating to a voice alarm system for bucket wheel stacker-reclaimers. Background Technology

[0002] The bucket wheel stacker-reclaimer mainly consists of a traveling mechanism, a slewing mechanism, a pitching mechanism, a cantilever belt, a bucket wheel mechanism, a tail car, a guide chute, and a hopper. When the cantilever belt rotates forward, the bucket wheel rotates, and the collected material is transported to the central hopper via the cantilever belt, falling onto the main belt to achieve material collection. When the cantilever belt rotates in reverse, the goods transported by the main belt pass through the tail car and the hopper, falling onto the cantilever belt and being dumped into the stockpile to achieve material stacking.

[0003] Every action of a bucket wheel stacker-reclaimer should be preceded by a warning and be precisely controllable to ensure the safe operation of the equipment. Therefore, this application provides a voice alarm system for a bucket wheel stacker-reclaimer, specifically designed for the safety protection of the stacker-reclaimer, which can take corresponding alarm measures based on the operating status of the stacker-reclaimer.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A voice alarm system for a bucket wheel stacker-reclaimer includes:

[0008] The PLC controller is used to issue action commands for each dynamic mechanism.

[0009] The digital output module is used to receive action commands from the PLC controller and output a DC high level through the corresponding relay;

[0010] The voice controller is used to accept the DC high level output from the corresponding relay and output sound by combining it with a loudspeaker;

[0011] The warning light is used to receive a DC high-level output from the corresponding relay and to output a flashing light.

[0012] Preferably, the system also includes a communication module and an I / O module; the communication module is used to enable communication between the PLC controller and each module; the I / O module is used to transmit commands.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The voice alarm system of the bucket wheel stacker-reclaimer of the present invention is developed based on PLC. Through sensors and protection limit switches, the various mechanisms are coordinated to realize the stacking and reclaiming of materials. Moreover, the system can provide prompts for each step of the mechanism through voice and light, which helps to ensure the safe operation of the equipment. Attached Figure Description

[0015] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] See attached document Figure 1 A voice alarm system for a bucket wheel stacker-reclaimer includes:

[0019] The PLC controller is used to issue action commands for each dynamic mechanism.

[0020] The digital output module is used to receive action commands from the PLC controller and output a DC high level through the corresponding relay;

[0021] The voice controller is used to accept the DC high level output from the corresponding relay and output sound by combining it with a loudspeaker;

[0022] The warning light is used to receive a DC high-level output from the corresponding relay and to output a flashing light.

[0023] In this embodiment, the system also includes a communication module and an I / O module; the communication module is used to connect the PLC controller with each module, and the I / O module is used to transmit commands. Through sensors and protection limit switches, the various mechanisms coordinate to achieve the stacking and retrieving of materials.

[0024] This utility model's voice alarm system for a bucket wheel stacker-reclaimer uses a small PLC as its core. It issues commands for the actions of various dynamic mechanisms, which are then transmitted via digital output modules and corresponding relays to output a high-level DC signal. When a high-level command is input to the voice controller, it outputs sound in conjunction with a loudspeaker; when a high-level command is input to a flashing warning light, it flashes a light.

[0025] In addition, before the loudspeaker broadcasts the message, the voice controller needs to perform a voice format conversion, converting the text information into speech before outputting the sound through the loudspeaker.

[0026] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
