Abstract
The invention discloses a flexible protecting net for a hydraulic bracket of a coal mine. The flexible protecting net comprises a protecting net, wherein the protecting net is of a rectangular structure, and consists of a flexible steel wire net, steel wire ropes, an upper connecting plate and a lower connecting plate; the steel wire ropes are arranged at the edges of left side and right side of the flexible steel wire net; the upper connecting plate and the lower connecting plate are arranged at the upper edge and lower edge of the flexible steel wire net; at least two upper lug rings are spaced on the upper connecting plate, and are respectively connected with a spring balance device; at least two connecting members are spaced on the lower connecting plate, and are used as ring chains. The flexible protecting net has the advantages that the problems of low protection height and protection failure of surface plating layer of hydraulic vertical columns of the traditional rigid steel net are solved; the labor intensity of maintenance workers is decreased, the productivity is improved, and the maintenance, loading and unloading by workers under the well are convenient.
Description
Technical field
The present invention relates to coal-mine hydraulic support, be especially for the soft protecting net of coal mine hydraulic supporting.
Background technology
At present, the protection network that mine underground hydraulic support is used uses hard steel mesh mostly, is fixed between two front columns of hydraulic support, and during for preventing coal work, the coal cinder of avalanche jeopardizes the safety of staff.For the hydraulic support of relatively high working face, extension type typically made by hard steel mesh, uses height with support lift adjustment.But, due to the restriction of converted steel web frame, regulation height can not be the highest, and this coal cinder allowing for avalanche often flies into walkway from the online side of converted steel and jeopardizes the safety of workman.Further, hydraulic vertical prop can not be protected by the hard steel mesh of this kind of structure, causes hydraulic vertical prop overlay coating easily to be broken by the coal cinder of avalanche.
Summary of the invention
Present invention aim at providing a kind of soft protecting net for coal mine hydraulic supporting.
For achieving the above object, the present invention takes following technical proposals:
Soft protecting net for coal mine hydraulic supporting of the present invention, including the protection network of rectangular configuration, steel wire rope that the protection network of described rectangular configuration by flexible steel silk screen and is arranged on described flexible steel silk screen left and right sides edge and be arranged on the online edge of flexible steel wire and the upper junction plate of lower edge, lower connecting plate form；Being arranged at intervals with earrings at least two on described upper junction plate, described each upper earrings is connected to a Spring balancer；At least two connecting elements it is arranged at intervals with on described lower connecting plate.
Being arranged on the connecting elements on described lower connecting plate is loop chain.
The invention has the advantages that and solve conventional rigid steel mesh protection insufficient height and hydraulic vertical prop overlay coating problem can not be protected.Reduce service worker labor intensity simultaneously, improve productivity ratio, the purpose facilitating underground labour to keep in repair and loading and unloading.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the use view of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, soft protecting net for coal mine hydraulic supporting of the present invention, protection network including rectangular configuration, the protection network of described rectangular configuration is by flexible steel silk screen 1 and the steel wire rope 2,3 that is arranged on described flexible steel silk screen 1 left and right side edge, and is arranged on the upper junction plate 4 at the upper and lower edge of flexible steel silk screen 1 and lower connecting plate 5 forms；Being arranged at intervals with two upper earrings 6,7 on described upper junction plate 4, described each upper earrings 6,7 is connected to one for the Spring balancer 9,10 being connected with hydraulic support top beam 8；Two it are arranged at intervals with for the loop chain 12,13 being connected with hydraulic support foundation 11 on described lower connecting plate 5.
During hydraulic support work, the built-in steel wire rope 14 of Spring balancer 9,10 pulls out to be tightened flexible steel silk screen 1, it is achieved walkway and the double protection of column 15, reaches to collapse when effectively stopping coal mining and flies coal cinder and enter walkway or impact damage column 15 coating purpose.
