Abstract

The utility model discloses the operator guards of a kind of coal mine gob base plate monitoring line; it comprises the groove (7) of excavation on floor rock (8) surface; pvc pipe (2) is equipped with in described groove (7); monitoring line (1) is placed in this pvc and manages in (2); the outside of described pvc pipe (2) is enclosed with spongy layer (5); the outside of described spongy layer (5) is filled with cinder layer (6), the upper end face of this cinder layer (6) and suitable for reading the flushing of groove (7).The utility model protected effect is desirable, because whole monitoring line is all the mode adopting side to enter, not only not easily scratches monitoring line, only need open step by step and overhauling, greatly reducing installation and the cost of overhaul when overhauling.

Description

The operator guards of a kind of coal mine gob base plate monitoring line

Technical field

The utility model relates to mining cable protector, what be specifically related to is the operator guards that a kind of coal mine gob base plate monitors line.

Background technology

In order to ensure that the safety of coal work is carried out, under the impact of disaster, need to the fire causing goaf hidden danger, water, gas, press, environment etc. monitors in real time.At present, limit by condition, have to adopt the mode of wire transmission signal in the monitoring system of coal mine gob, underground coal mine bad environments and coal-face are constantly pushed ahead along with production process, bring very large inconvenience to the maintenance of supervisory control system.Especially the injuring by a crashing object across the falling rocks falling to causing of roof overburden, pound disconnected monitor signal line, cause system cannot continue monitoring, and be difficult to repair, cause great threat to safety monitoring.

For this phenomenon; common way wears a protection tube in the outside of monitoring line; although this kind of structure can in certain degree monitoring for protection line; but threading process trouble very, and very easily scratch monitoring line, once be damaged; whole protection tube is needed to trip out completely; and the extraction of monitoring line just can be checked that trouble very greatly reduces the operating efficiency of maintenance.

Utility model content

The utility model object is to provide the operator guards of a kind of coal mine gob base plate monitoring line, and it can solve problem existing in background technology effectively.

The operator guards of a kind of coal mine gob base plate monitoring line; it comprises the groove 7 of excavation on floor rock 8 surface; pvc pipe 2 is equipped with in described groove 7; monitoring line 1 is placed in this pvc pipe 2; the outside of described pvc pipe 2 is enclosed with spongy layer 5; the outside of described spongy layer 5 is filled with cinder layer 6, and the upper end face of this cinder layer 6 flushes with the suitable for reading of groove 7.

The head and the tail two ends of described pvc pipe 2 are respectively equipped with the interface 9 of docking mutually.

Described pvc pipe 2 entirety is axially fasten all-in-one-piece tubular structure, and the side of its junction is provided with hinge 3, and its opposite side is provided with corresponding snap close 4.

Owing to have employed above technical scheme; the utility model has following beneficial effect: protected effect is desirable, because whole monitoring line is all the mode adopting side to enter, not only not easily scratches monitoring line; only need open step by step when overhauling and overhaul, greatly reduce installation and the cost of overhaul.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of pvc pipe in the utility model;

Fig. 3 is the cutaway view of Fig. 2.

Embodiment

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment being clearly and completely described.

Embodiment 1

Referring to Fig. 1-3; the operator guards of a kind of coal mine gob base plate monitoring line; it comprises the groove 7 of excavation on floor rock 8 surface; pvc pipe 2 is equipped with in described groove 7; monitoring line 1 is placed in this pvc pipe 2; the outside of described pvc pipe 2 is enclosed with spongy layer 5, and the outside of described spongy layer 5 is filled with cinder layer 6, and the upper end face of this cinder layer 6 flushes with the suitable for reading of groove 7.

Embodiment 2

Referring to Fig. 1-3, the method for embedding of a kind of coal mine gob base plate monitoring line, is achieved by following steps:

1) first lay monitoring line 1 at return airway, then on floor rock 8, dig a groove 7 near coal side, then monitoring line 1 is placed in groove 7;

2) under the effect of hinge 3, open the snap close 4 on pvc pipe 2, monitoring line 1 is put into pvc pipe 2 successively;

3) rear being connected is docked between the head and the tail of every root pvc pipe 2 by interface 9;

4) then wrap to the pvc pipe 2 connected with spongy layer 5;

5) finally with cinder 6, spongy layer 5 and pvc pipe 2 are covered again.Through the process of above-mentioned measure, monitoring line 1 is carried out effective protection, has avoided the destruction of falling rocks, ensure that the safe operation of monitoring system.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
