Abstract

The utility model discloses a track gangue-blocking device of a large dip angle working face hydraulic support, which is characterized in that the track gangue-blocking device comprises a protective plate (2) and a protective jack (3), wherein the upper end of the protective jack (3) is articulated at one side of a support top beam (1); the upper end of the protective plate (2) is articulated at the other side of the support top beam (1); and a piston rod of the protective jack (3) is articulated with the protective plate (2). The track gangue-blocking device can be arranged on the large dip angle working face hydraulic support, the dropping coal briquettes and gangues above a roof in the coal mining process can be blocked, the safety above the coal face can be effectively maintained and the safety below the unit is protected, thereby improving the production efficiency of the coal mine and saving the labor cost.

Description

A kind of large inclination working surface hydraulic support machine road retaining cash device
Technical field
The utility model belongs to the coal mine machinery technical field, is specifically related to a kind of large inclination working surface hydraulic support machine road retaining cash device.
Background technology
Comprehensive mechanical coal mining is the important symbol of coal mining technological progress, is that the colliery increases output, raises labour efficiency, increases the important means of economic benefit.The fully-mechanized mining equipment that the comprehensive core of adopting technology of high-yield and high-efficiency is a coal-face, fully-mechanized mining working have three big corollary equipment-coal-winning machines, drag conveyor, hydraulic support, and wherein hydraulic support is one of capital equipment of fully-mechanized mining working.Because the angle of large inclination working surface own is bigger, after the coal cutting of coal-winning machine unit, the spoil in the top board sky can fall, and smashes the unit of below, influences coal work efficient, causes unnecessary economic loss.
The utility model content
The purpose of this utility model is to provide a kind of large inclination working surface hydraulic support machine road retaining cash device, in order to safeguard the safety of coal-face top, the safety of the following unit of protection.
The technical solution of the utility model is as follows:
Large inclination working surface hydraulic support machine road retaining cash device, it is characterized in that: this road retaining cash device comprises protected apron and protection jack, protection jack upper end is hinged on a side of set cap, the upper end of protected apron is hinged on the opposite side of set cap, and the piston rod and the protected apron of protection jack are hinged.
Described protected apron is provided with peep hole.
This use is novel to be installed on the large inclination working surface hydraulic support, can stop the coal cinder, spoil of the overhead landing of top board in the coal mining process etc., can effectively safeguard the safety of coal-face top, the safety of unit below the protection.Thereby improve the production efficiency in colliery, save labour cost.
Description of drawings
Fig. 1 is the structural representation of retaining cash device open mode hydraulic support;
Fig. 2 is the structural representation of retaining cash folding device state hydraulic support;
Fig. 3 keeps off the K of cash device part to view among Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 3, large inclination working surface hydraulic support machine of the present utility model road retaining cash device, comprise protected apron 2 and protection jack 3, protection jack 3 upper ends are hinged on a side of set cap 1, the upper end of protected apron 2 is hinged on the opposite side of set cap 1, and the piston rod and the protected apron 2 of protection jack 3 are hinged.
Described protected apron 2 is provided with peep hole 4.
Operating principle of the present utility model is as follows: during construction, the piston rod of protection jack 3 stretches out under the hydraulic power support, and protected apron 2 is opened, and plays the effect (as Fig. 1) in protection work plane machine road like this.When not constructing, the piston rod of protection jack 3 shrinks under hydraulic power is supported, makes protected apron 2 folding (as Fig. 2).Among Fig. 3, the state diagram when solid line represents that keeping off the cash device opens, the state diagram when dotted line is represented to keep off the cash folding device.

Claims (2)

1. a large inclination working surface hydraulic support machine road keeps off the cash device, it is characterized in that: this road retaining cash device comprises protected apron (2) and protection jack (3), protection jack (3) upper end is hinged on a side of set cap (1), the upper end of protected apron (2) is hinged on the opposite side of set cap (1), and the piston rod and the protected apron (2) of protection jack (3) are hinged.
2. large inclination working surface hydraulic support machine according to claim 1 road retaining cash device is characterized in that: be provided with peep hole (4) on described protected apron (2).
