Abstract

The utility model provides a device for preventing an unmanned trolley from colliding into a fireproof door. The device comprises a proximity switch (1), a relay (2), an audible and visual alarm (3), a master control cabinet (4), and an unmanned trolley (5) with the wireless communication function, wherein the signal source end (1a) of the proximity switch (1) is connected with the relay (2) and the master control cabinet (4) in sequence; the other end of the relay (2) is connected with the master control cabinet (4); one contact point of the relay (2) is connected with the audible and visual alarm (3); the unmanned trolley (5) with the wireless communication function receives signals from the master control cabinet (4) and move correspondingly according to the received signals. According to the utility model, the device can be used for controlling potential hazard sources of the opening or closing of a fireproof door on site, has the alarming function and can prevent the fault that the unmanned trolley collides into the fireproof door, so that the maintenance cost of the device is reduced and the operation reliability of the device is improved excellently.

Description

A kind of device that prevents unmanned dolly collision fire protection gate

[technical field]

The utility model relates to unmanned cart system transformation and electrical design, particularly a kind of device that prevents unmanned dolly collision fire protection gate.

[background technology]

Now, a lot of unmanned cart systems lack the control to potential dangers such as on-the-spot fire protection gates, if fire protection gate is to reaching position completely or having closed, the material of fire protection gate cannot make unmanned dolly receive block signal, unmanned dolly can knock fire protection gate by force, cause unmanned little vehicle device and fire protection gate to occur damage in various degree, affect stabilization of equipment performance.

[utility model content]

For the problems referred to above, the utility model provides a kind of device that prevents unmanned dolly collision fire protection gate, and the technical solution of the utility model is as follows:

A kind of device that prevents unmanned dolly collision fire protection gate, comprise approach switch 1, relay 2, combined aural and visual alarm 3, the overhead control cabinet 4 and the unmanned dolly 5 with radio communication with radio communication, the signal source 1a of described approach switch 1 sequentially connects described relay 2 and described overhead control cabinet 4; Described relay 2 other ends are connected with described overhead control cabinet 4, and described relay 2 one contacts are connected with described combined aural and visual alarm 3, described in there is radio communication unmanned dolly 5 receive the signal from overhead control cabinet 4, make corresponding action according to the signal receiving.

Further, described approach switch 1, the positive-negative power of relay 2 and combined aural and visual alarm 3 is all taken from described overhead control cabinet 4.

Further, described approach switch 1 is arranged on fire protection gate 5 sides, fixing on the wall by support 6.

The utility model compared with prior art has the following advantages:

1, a kind of device that prevents unmanned dolly collision fire protection gate described in the utility model can open or close potential danger source to on-the-spot fire protection gate and make control;

2, a kind of device that prevents unmanned dolly collision fire protection gate described in the utility model can be got a warning function and can judge fast which fire protection gate breaks down staff with combined aural and visual alarm;

3, a kind of device that prevents unmanned dolly collision fire protection gate described in the utility model can prevent unmanned dolly to collide the generation of fire protection gate fault, saves the service expenditure of equipment, and has well improved equipment serviceability.

Brief description of the drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is that a kind of device that prevents unmanned dolly collision fire protection gate of the utility model connects block diagram;

Fig. 2 is a kind of device mounting circuit figure that prevents unmanned dolly collision fire protection gate of the utility model;

Fig. 3 is the mounting means figure of approach switch in a kind of device that prevents unmanned dolly collision fire protection gate of the utility model.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, a kind of device that prevents unmanned dolly collision fire protection gate, comprise approach switch 1, relay 2, combined aural and visual alarm 3, overhead control cabinet 4 and the unmanned dolly 5 that disposes radio communication, the signal source (1a) of described approach switch 1 sequentially connects described relay 2 and described overhead control cabinet 4; Described relay 2 other ends are connected with described overhead control cabinet 4, and described relay 2 one contacts are connected with described combined aural and visual alarm 3, described in there is radio communication unmanned dolly 5 receive the signal from overhead control cabinet 4.Described approach switch 1, the positive-negative power of relay 2 and combined aural and visual alarm 3 is all taken from described overhead control cabinet 4.Described approach switch 1 is arranged on fire protection gate 5 sides, fixing on the wall by support 6, to ensure the stability of approach switch 1 induced signal.

In the time that approach switch 1 senses that fire protection gate is closed or does not reach, the signal source (1a) of approach switch 1 can inspire relay 2 and move open contact closure, combined aural and visual alarm 3 is reported to the police, staff is played the effect of a warning and can judge fast which fire protection gate breaks down; The signal that the cabinet of overhead control simultaneously 4 receives from approach switch 1, after analyzing this signal, overhead control cabinet 4 sends block signal by radio communication to unmanned dolly 5, by radio communication, unmanned dolly 5 is controlled unmanned dolly 5 according to the obstruction signal receiving and is stopped exercising.

When sensing fire protection gate, opens completely approach switch 1, the signal source (1a) of approach switch 1 inspires relay 2 open contacts and disconnects, combined aural and visual alarm 3 stop alarms, the block signal that the cabinet of overhead control simultaneously 4 transmits to unmanned dolly 5 disappears, and unmanned dolly 5 continues to exercise by fire protection gate automatically.

Above-mentioned explanation illustrates and has described preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in utility model contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
