Abstract
The utility model relates to a device for preventing coal wall caving of a working face from causing personal injuries, which is used for raising safety of the coal-mining working face. Two oil cylinders and a protective net are mounted on a working face support top beam. The protective net is regulated through the two oil cylinders, so as to effectively prevent coal briquettes falling from wall caving from splashing to a support and from causing personal injuries. The protective net is made from polyester fiber materials and thus has the characteristics of flame retardance, corrosion resistance, ageing resistance, high strength, high node strength, softness and the like. The protective net is mounted at a position between the support top beam and a face guard, the protective width of the protective net is equal to the width of the support, and the height of the protective net is determined by the size of the support. Because the protective net has the characteristics of high strength, ageing resistance and the like, unnecessary injuries caused by coal wall caving can be effectively prevented. In this manner, security is effectively ensured and production efficiency is accelerated.
Description
Technical field
The utility model relates to a kind of device that prevents that the wall caving personnel that cause from injuring, and is specifically related to a kind of device that prevents that the working face wall wall caving personnel that cause from injuring.
Background technology
The supporting of support is the main support pattern of current mine production operation, and stent car has supporting, puts the characteristics such as coal.The support that existing large mining height fully-mechanized coalface is used is along with scientific and technological development, and mining height is increasing.Be accompanied by corresponding problem, due to the increase of mining height, the wall caving situation of working face wall is day by day cumulative.Make coal production have certain potential safety hazard.
Summary of the invention
In order to address the above problem, the utility model provides a kind of device that prevents that the working face wall wall caving personnel that cause from injuring, and this device can be kept out by wall caving and be caused the serious situation of coal breakage, for the safety of High-efficient Production provides safeguard.
The utility model solves the technical scheme that its technical problem adopts: a kind of device that prevents that the working face wall wall caving personnel that cause from injuring, back timber at force piece is installed two oil cylinders and a polyester fiber protective screening, between oil cylinder and back timber, by connecting rod, fixes.And, by the hydraulic control system on support, control the flexible of oil cylinder, thereby reach the protection to working face wall.
Good effect of the present utility model is: cost is little, mobility is high, security performance is good.The personnel that the working face wall wall caving causes that prevent that can be effectively positive injure problem, have greatly improved the potential safety hazard of colliery High-efficient Production, have promoted the production efficiency of large-mining-height working surface.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The structure chart when integral body that Fig. 1 is support and utility model is not used.
The structure chart when integral body that Fig. 2 is support and utility model is used.
In figure: 1, set cap, 2, oil cylinder, 3, the polyester fiber protective screening, 4, connecting rod, 5, hydraulic control system, 6, face guard.
The specific embodiment
As shown in Figure 1 and Figure 2: a kind of device that prevents that the working face wall wall caving personnel that cause from injuring, at set cap (1), oil cylinder (2) is installed, and a slice polyester fiber protective screening (3) is installed between oil cylinder (2) and face guard (6), and by connecting rod (4), oil cylinder is fixed on back timber, control the flexible of oil cylinder (2) and face guard (6) by hydraulic control system (5), realize protecting the danger that the coal wall caving personnel that cause injure.Polyester fiber protective screening (3) has the characteristics such as fire-retardant, corrosion-resistant, anti-aging, that intensity is high, and node intensity is high, soft.The utility model infrastructure cost is little, mobility is high, security performance is good.The personnel that the working face wall wall caving causes that prevent that can be effectively positive injure problem, have greatly improved the potential safety hazard of colliery High-efficient Production, have promoted the production efficiency of large-mining-height working surface, have more promotional value.
Claims (1)
1. a device that prevents that the working face wall wall caving personnel that cause from injuring; it is characterized in that: two oil cylinders (2) are installed in the back timber position at support (1); and be fixed on support by connecting rod (4); and polyester fiber protective screening (3) is installed between oil cylinder (2) and face guard (6); control the flexible of oil cylinder and face guard (6) by hydraulic control system (5), make effectively Protection personnel of protective screening (3).
