The rock burst ejection protection device is simple in structure, convenient to use, low in manufacturing cost and easy to maintain, solves the problem that rock burst ejection is lack of protection caused by rock burst in the prior art through the simple structure, achieves comprehensive protection and safety protection of a working face, is simple and rapid in equipment arrangement, and has great market popularization value.
Description
Technical Field
The utility model relates to the field of underground safety equipment, in particular to an anti-rock-burst combined anchor net cable.
Background
Deep or tectonic areas of underground mining where stresses are high, or by rock bursts, i.e. the phenomenon of sudden failure in the rock mass in the immediate vicinity of the hole. The rock burst is one of the main potential safety hazards faced by deep-well mines, the slight rock burst only strips rock slices, no ejection phenomenon exists, 4.6-level seismic intensity can be measured seriously, and the rock slice ejection phenomenon is accompanied. For the above situations, the existing treatment mode generally adopts hydraulic support rod support, but for the rock fragment ejection situation, corresponding special protection measures or tools are still lacked.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the anti-rock-burst combined anchor net cable which is simple in structure, safe, reliable and convenient to use.
The equipment comprises a main body supporting rod, wherein the main body supporting rod is a main body supporting piece of the equipment; two main body supporting rods are oppositely arranged, and a protective net is arranged between the two main body supporting rods;
the locking device is fixedly arranged on the main body supporting rod and comprises a ball head bearing, and a locking clamp is fixedly arranged on the ball head bearing.
Furthermore, each of the holding and locking devices on the accurate lifting support rod is at least provided with two holding and locking devices, and the holding and locking devices are arranged in an even array mode.
That is to say, embrace the setting of locking clamp corresponding hydraulic pressure branch, it is fixed through embracing the locking clamp on adjacent hydraulic pressure branch, the protection network protection that is fixed in the rock fragment of realization equipment.
Further, the opposite side edges of the locking device are provided with protective net clamping pieces on the main body supporting rods, and the protective net clamping pieces are provided with fastening devices.
Further, the protective net is a steel woven net.
The utility model has the beneficial effects that: the rock burst ejection protection device is simple in structure, convenient to use, low in manufacturing cost and easy to maintain, solves the problem that rock burst ejection is lack of protection caused by rock burst in the prior art through the simple structure, achieves comprehensive protection and safety protection of a working face, is simple and rapid in equipment arrangement, and has great market popularization value.

The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
Referring to fig. 1, the anti-rock-burst combined anchor net cable of the present invention comprises a main body support rod 4, wherein the main body support rod 4 is a main body support member of the present apparatus; two main body supporting rods are oppositely arranged, and a protective net 3 is arranged between the two main body supporting rods 4;
on the main part bracing piece 4, fixed locking device 1 that is provided with, locking device 1 includes the bulb bearing, the fixed locking clamp that is provided with on the bulb bearing.
Furthermore, the holding and locking device 1 on each accurate lifting support rod is at least provided with two, and the arrangement form is uniform array arrangement.
That is to say, embrace the setting of locking clamp corresponding hydraulic pressure branch, it is fixed through embracing the locking clamp on adjacent hydraulic pressure branch, realize that the protection network 3 that is fixed in the rock fragment of equipment protects.
Further, the opposite side edges of the locking device 1 are provided with protective net clamping pieces 2 on the main body supporting rod 4, and the protective net clamping pieces 2 are provided with fastening devices.
Preferably, the protective net clamping pieces 2 are in the form of two wing plates arranged in two rows, and a gap between the two wing plates is used for placing the protective net 3;
the fastening device can adopt a form of penetrating a bolt to match with a nut to limit the protective net 3.
Further, the protection net 3 is a steel woven net.
That is, the protection net 3 is cut according to the arrangement of the hydraulic struts, and the main body support rods 4 are respectively assembled at both ends thereof, that is, the protection net 3 is placed on the protection net clips 2 and fixed. Utilize to embrace and lock the clamp and wholly lock equipment between two hydraulic prop, the setting of ball head bearing is promptly to avoid setting up the inconvenient assembly that the direction slope leads to because of hydraulic prop, plays the effect of nimble assembly.
While there have been shown and described what are at present considered the fundamental principles and essential features of the utility model and its advantages, it will be apparent to those skilled in the art that the utility model is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
