Abstract
The invention relates to a method for monitoring a push jack of a support shield used in underground mining. Acceleration transducers are arranged to measure the positions of the push jack.
Description
Technical field
The present invention relates to a kind of method and apparatus of the advancing jack (Schreitzylinder) for monitoring underground mining shield support used (Ausbauschild).
Background technology
By technical background, learnt, at the inner stroke measurment that adopts length measuring system to realize advancing jack of hydraulic jack.For example apply for this purpose Reed (tongue tube) measuring staff or ultrasonic measuring of length system.But such measuring system for shield support renovate or for very simple shield support cost all higher.
Summary of the invention
Therefore the object of the invention is to propose a kind of for monitoring the method and apparatus of advancing jack, utilize the method and device can not change advancing jack, in situation cheaply, realize the monitoring to advancing jack, the namely monitoring to its each position.
This object realizes by the feature described in independent claims, especially by a kind of method of the very heavy item of passing of monitoring underground mining shield support used, this shield support has at least one base (Kufe) and a back timber (Kappe), between them, arranged at least one pillar, wherein on shield support, be provided with at least one probe, it comprises at least two and be preferably three acceleration transducers, and their measurement axis extends substantially mutually orthogonally.
By DE 102007035848A1, learn a kind of shield support, it has the probe of described type above, and the whole content of this shield support fully becomes the content of present patent application by reference.
In order to monitor the position of advancing jack, according to the present invention, make its motion and gather by probe at the accekeration of surveying between advancing jack moving period.Then by the accekeration gathering, obtained the position of advancing jack.
The present invention based on understanding be, by means of design on shield support or the also acceleration transducer on push unit, can identify the position of advancing jack, this is because conventionally produced new position owing to moving smoothly in provided jack stroke inside.Utilizing probe also can illustrate with what pattern and mode stops shield support.If for example shield support interrupts suddenly motion after having passed through LAP, the trip is roughly equivalent to the range of jack, can infer so thus, and advancing jack has arrived its terminal location.If contrary, during stroke, move and interrupt and reduce at leisure in this speed, can infer so thus, shield support is stuck, and can be realized and fully be moved frame by normal recovery (Rauben).This process also can utilize again probe to monitor, and whether this is moved again and reached terminal location because acceleration transducer can detect shield support.
Advantageous forms of implementation of the present invention is illustrated in manual, accompanying drawing and dependent claims.
The accekeration that probe can be surveyed according to the first favourable form of implementation carries out integration, to obtain the speed of motion.In this way can infer that whether shield support advances in accordance with regulations, and if be, advances in which way.
The form of implementation favourable according to another kind, can be obtained by surveyed accekeration the stroke of advancing jack process, and its mode is for example the acceleration by carrying out in time integration to be carried out to integration again.
In addition the form of implementation favourable according to another kind, can and consider that by surveyed accekeration the range of advancing jack obtains, and whether advancing jack reaches its terminal location.If the known range of advancing jack, so can be by the contrast of terminal location, that is to say that according to speed, dropping to zero determines, whether whether the range of advancing jack realize, or be not so substantially.
In addition according to another advantageous forms of implementation, when not reaching terminal location, shield support can be reclaimed to (geraubt), and then automatically again handle advancing jack, to also move frame (Schreiten) when shield support mounting board.
Maybe advantageously, when advancing jack setting in motion, just start sense acceleration value, because guaranteed in this case not detect other effect for shield support.By the same token maybe advantageously, is not activating other jack of shield support between advancing jack moving period, and this is because otherwise may obtain wrong measured value.
According to invention, be also provided with a kind ofly for implementing the control device of described method above, utilize this control device will pass the very heavy accekeration of being surveyed by probe that activate and detect.In addition the accekeration that control device can be surveyed by means of microprocessor is obtained the position of advancing jack, for example, make the accekeration of obtaining carry out integration twice to the time.In addition the range of passing very heavy can be inputed in control device, thereby can determine by comparison means, whether the stroke of the advancing jack process of obtaining by means of probe is equivalent to the range of advancing jack substantially.
The probe with acceleration transducer can be assemblied on the back timber (Kappe) of shield support.But also can be fixed on base or thrust gear (Schreitwerk) from it because just can detect therein its acceleration in every kind of situation when shield support moves.
Accompanying drawing explanation
Pure exemplarily according to a kind of favourable form of implementation and the present invention will be described with reference to accompanying drawing below.Be depicted as:
Fig. 1 is the lateral view of shield support; With
Fig. 2 is the diagram of gathered accekeration and the speed change curves calculating thus and the stroke of passing by.
The specific embodiment
Fig. 1 has represented the shield support arranging, and it has two bases 14, and they are connected with back timber 22 by pillar 18 respectively.Label 24 and 26 has represented the connecting rod in quadric chain, and they are connected with caving shield 28.
Utilize label 32 to represent a probe purely simply illustrating, it is fixed on the bottom surface of back timber 22.Probe 32 has the accelerator sensor separating in three structures in an illustrated embodiment, their the mutually orthogonal extension of measurement axis, thereby can not depend on installation site and both realize in a longitudinal direction acceleration measurement in a lateral direction.Be roughly ± 1g of the measurement category of acceleration transducer used.In addition alternately or additionally on caving shield 28 and/or on one or two connecting rod 24 and 26, probe also can be set.Probe also can be used as obliquity sensor, as this described in the DE 102007035848.
In addition the shield support shown in Fig. 1 has the thrust gear with an advancing jack 34, and this advancing jack is fixed on conveyer 35, and can be integrated with length measuring system in this jack.For redundancy, or when length measuring system lost efficacy, can be by the position of the signal measuring advancing jack 34 of probe 32.
Be connected with control device with shield support recited above, it is by means of the inclination detector being arranged in connecting rod 24 and 26 on any, and another is arranged on another inclination detector on caving shield 28 and calculates the rise height of support.This calculating is because applied inclination detector can independently carry out with the fore-and-aft tilt of support or lateral inclination.
(unshowned in the accompanying drawings) control device is connected with probe 32, and on the one hand when needed, triggers the motion of advancing jack.On the other hand with the synchronized movement of advancing jack detect, between advancing jack moving period, by the acceleration transducer of probe 32, measure its accekeration.These values are stored and for example according to the time, as change curve A, are illustrated in Fig. 2.Owing to having friction, shield support has positive and negative acceleration, wherein at the terminal acceleration of advancing jack range, drops to suddenly zero.
By accekeration integration in time, can obtain current speed by control device, it illustrates by dotted line B.By integration again finally can obtain advancing jack and be also therefore shield support the stroke of process, the trip is shown in Figure 2 with dotted line C.
Stroke value that survey by contrast and accekeration, velocity amplitude or process calculating, and by obtaining with the range of (known) advancing jack, whether advancing jack arrives its terminal location.If do not reached, control device can automatically again reclaim and follow manipulation so, that is to say that activating advancing jack stretches out and/or regain, thereby makes it still arrive its terminal location.
