Description
Technical field
The utility model relates to building field, specifically a kind of modified non-excavating construction rig.
Background technology
In non-excavating construction, the operating personnel might can't predict situations such as the concrete trend, buried depth of network of underground, and it is crossing therefore just might to meet underground high voltage cable in adopting drilling machine construction.As shown in Figure 1, it is the vivid schematic diagram of general rig, and rig generally comprises the drill bit 3 that sets gradually, drilling rod 2, bores body 1 and ground connection anchor 4, when drill bit 3 is charged, drill bit 3, drilling rod 2, bore body 1, ground connection anchor 4 forms electrical loop and leads away electric energy.When rig ran into underground high voltage cable 5, high voltage cable 5 was very easily got into by drill bit 3 and breakage.Therefore, after high voltage cable 5 breakages, the high voltage of moment can pass through drill bit 3, drilling rod 2, brill body 1, ground connection anchor 4 and the earth formation moment high potential.Yet,, step voltage can take place when arbitrarily walking about get an electric shock owing to do not know what's going on the operating personnel of rig periphery, bring great operating risk.
The utility model content
In view of this, the utility model is necessary to provide a kind of modified non-excavating construction rig, and it can be when rig and the earth formation moment high potential, and the related personnel around the caution rig is mobile, reduces the risk of step voltage electric shock.
The utility model is achieved in that a kind of modified non-excavating construction rig, and it comprises drill bit, drilling rod, brill body and the ground connection anchor that sets gradually; Be arranged with the warning sleeve on this drilling rod, this warning sleeve comprises tubular shell and warning circuit; This warning circuit comprise tubular induction coil, photoelectrical coupler, pull-up resistor, on draw power supply, CPU, voice cue module; This tubular induction coil is enclosed in the sidewall interlayer of this tubular shell, and concentric with this tubular shell, this photoelectrical coupler, this pull-up resistor, draws power supply, this CPU, this voice cue module to be installed on this tubular shell on this; This CPU has trigger end and control end, and this control end connects this voice cue module, and this trigger end is connected in via this pull-up resistor and draws power supply on this; The two ends of this tubular induction coil are connected to the two ends of the light emitting diode of this photoelectrical coupler, and the colelctor electrode of the triode of this photoelectrical coupler is connected in this trigger end, the electrical ground connection of its emitter stage.
As the further improvement of such scheme, this photoelectrical coupler, this pull-up resistor, draw power supply, this CPU, this voice cue module to be arranged on the circuit board on this, this circuit board is fixed on this tubular shell.
Preferably, this circuit board is fixed on the lateral wall of this tubular shell.
Again preferably, the lateral wall of this tubular shell is provided with mounting groove, and this circuit board is housed in this mounting groove.
Modified non-excavating construction rig of the present utility model can protect related personnel around the rig such as operating personnel when rig taking place get an electric shock, and step voltage can not take place because walking about get an electric shock.
Description of drawings
Fig. 1 is the structural representation that existing modified non-excavating construction is used rig.
The modified non-excavating construction that Fig. 2 provides for the utility model preferred embodiments frame for movement schematic diagram of the warning sleeve of rig.
Fig. 3 is the electrical block diagram of warning sleeve among Fig. 2.
Main symbol description: bore body 1, drilling rod 2, drill bit 3, ground connection anchor 4, high voltage cable 5, tubular shell 6, CPU 7, voice cue module 8, photoelectrical coupler 9, tubular induction coil L, pull-up resistor R, on draw power Vcc, light emitting diode D, triode Q.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 2, its modified non-excavating construction that provides for the utility model preferred embodiments frame for movement schematic diagram of the warning sleeve of rig.The modified non-excavating construction that the warning jacket casing is located at is as shown in Figure 1 used on the drilling rod 2 of rig, and this warning sleeve comprises tubular shell 6 and warning circuit (not shown).Please in conjunction with Fig. 3, this warning circuit comprise tubular induction coil L, photoelectrical coupler 9, pull-up resistor R, on draw power Vcc, CPU 7, voice cue module 8.
This tubular induction coil L is enclosed in the sidewall interlayer of this tubular shell 6, and concentric with this tubular shell 6.Photoelectrical coupler 9, pull-up resistor R, on draw power Vcc, CPU 7, voice cue module 8 to be installed on this tubular shell 6.
This CPU 7 has trigger end and control end, and this control end connects this voice cue module 8, and this trigger end is connected in via this pull-up resistor R and draws power Vcc on this.After the trigger end of this CPU 7 was received triggering signal, the control end of this CPU 7 sent control signal driving voice cue module 8 and carries out voice suggestion, and the related personnel around the caution rig is mobile, reduces the risk of step voltage electric shock.
