Abstract
A kind of Anti-overturning protection device of tunnel arch machine; it is set on the front leg strut of arch machine comprising be mounted on and covered outside supporting leg close to switch, be installed on the pressure sensor for covering upper tablet in supporting leg and being mounted on the pressure born on support oil cylinder with real-time display front leg strut.So, when supporting leg inner sleeve reaches maximum position along the sliding of supporting leg housing, tablet can be detected close to switch and indicator light is bright, at this time, cantilever crane just starts to act, and is avoided that the faulty operation that cantilever crane just acts when front leg strut is not fully extended, can also prevent arch machine from acting cantilever crane in the case where front leg strut pressure is above or below setting pressure, to avoid tumbling.
Description
Technical field
The utility model relates to a kind of Anti-overturning protection devices of tunnel arch machine.
Background technique
In constructing tunnel, when country rock grade is poor, generally require to carry out arch supporting, to improve the stabilization of country rock
Property.In arch vertical using arch machine, needs to open arch machine supporting leg, supported arch machine to level using supporting leg.
In supporting leg opening procedure, if operation error, supporting leg is not fully extended to begin to operation cantilever crane, it is possible to cause
Arch machine is tumbled generation；When cantilever crane works, if cantilever crane payload overload, it will lead to front leg strut payload overload or rear support leg load be lower than
Safety value also has the possibility tumbled；If the bearing strength on ground is inadequate, can also encircle in addition, the ground of supporting leg support is unstable
Frame machine is tumbled.
Utility model content
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of tunnel arch
The Anti-overturning protection device of frame machine.
A kind of anti-dumping of tunnel arch machine that in order to solve the above technical problems, the technical scheme adopted by the utility model is:
Turn over protective device, which is characterized in that the device is set on the front leg strut of arch machine, including close switch, tablet and pressure
Sensor；This is installed on outside the supporting leg of front leg strut close to switch and puts on, which is installed on the supporting leg inner sleeve root of front leg strut,
When so that supporting leg inner sleeve reaching maximum position along the sliding of supporting leg housing, tablet can be detected close to switch；The pressure sensing
Device is installed on the pressure born on the support oil cylinder of front leg strut with real-time detection front leg strut.
It is put on outside the supporting leg of the front leg strut and is fixed with mounting plate, this is fixed on mounting plate close to switch.
Mounting blocks are fixed on the support oil cylinder of the front leg strut, which is installed on mounting blocks.
The pressure sensor is connected with control panel.
In this way, the present apparatus works as branch in putting on installing outside the supporting leg of front leg strut close to switching, putting on installing tablet in supporting leg
When leg inner sleeve reaches maximum length, tablet can be detected close to switch, and light close to switch, arch horn frame just starts
Movement；Meanwhile the present apparatus can display real-time the real-time pressure of front leg strut receiving in installing pressure sensor on support oil cylinder, when
When real-time pressure is more than front leg strut allowable stress, cantilever crane stopping movement；When minimum pressure of the real-time pressure lower than front leg strut setting
When power, also stopping acts cantilever crane, is avoided that tumbling for arch machine.
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the utility model close to switch scheme of installation.
Fig. 2 is the pressure sensor scheme of installation of the utility model.
Specific embodiment
The utility model be a kind of tunnel arch machine Anti-overturning protection device, be set to arch machine tool supporting leg housing 1,
On the front leg strut of supporting leg inner sleeve 2 and support oil cylinder 3.The Anti-overturning protection device includes passing close to switch 4, tablet 5 and pressure
Sensor 6.
Referring to Fig. 1, this is installed on the supporting leg housing 1 of front leg strut close to switch 4 by mounting plate 7, the tablet 5 installation
In 2 root of supporting leg inner sleeve of front leg strut, when so that supporting leg inner sleeve 2 reaching maximum position along the sliding of supporting leg housing 1, close to switch
4 can detect tablet 5, at this point, bright close to switch indication light (not shown), arch horn frame just starts to act.
Referring to fig. 2, which is installed on the support oil cylinder 3 of front leg strut by mounting blocks 8, the pressure sensing
Device 6 is connected to show the real-time pressure of front leg strut receiving with control panel (not shown), and compared with setting pressure, when
When front leg strut real-time pressure is more than allowable stress, arch horn frame stopping movement；When front leg strut real-time pressure is lower than setting
When minimum pressure, also stopping acts cantilever crane, to avoid tumbling for arch machine.
