Abstract
The utility model relates to a comprehensive mechanized mining large tilt angle working surface hydraulic bracket pedestrian passage waste rock blocking device which comprises a waste rock blocking beam, a waste rock blocking flashboard and a waste rock blocking jack. The upper end of the waste rock blocking beam is connected with a hydraulic bracket top beam and the lower end thereof is provided with the waste rock blocking flashboard. One end of the waste rock blocking jack is connected with the hydraulic bracket top beam and the other end thereof is connected with the waste rock blocking beam. The waste rock blocking device uses the waste rock blocking beam and the waste rock blocking flashboard to replace the original manual curtain device, thus having good waste rock blocking effect, and being safe and reliable. In addition, the waste rock blocking device adopts the waste rock blocking jack to control the tilt angle of the waste rock blocking flashboard, adopts a waste rock blocking flashboard jack to control the vertical height of the waste rock blocking flashboard, uses a full hydraulic automatic control, and reduces labor intensity.
Description
Technical field
The utility model belongs to the coal mine machinery technical field, is specifically related to a kind of comprehensive mechanical coal mining large inclination working surface hydraulic support walkway 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.
Comprehensive mechanical coal mining work plane high inclination-angle hydraulic support is a difficult point in the hydraulic support design, wherein protects pedestrains safety, is Safety of Coal Mine Production, the highly efficient and productive most important thing.Hydraulic support walkway " retaining cash device " is exactly the pedestrian space that a safety is provided for coal-face, guarantees the safety operation of mining.Because the large inclination working surface inclination angle is bigger, in process of production can the landing coal cinder, slungshot etc. drops on operator's walkway, hurts sb.'s feelings serious threat coal miner's life security easily." retaining cash device " is exactly to take measures on working surface hydraulic support, avoids the generation of this type of accident as possible.The existing retaining cash device that uses mainly is artificial curtain (as shown in Figure 1).Its shortcoming is: retaining cash chain (part 2) or belt retaining spoil, retaining cash weak effect; In addition, artificial curtain, labour intensity is big.
The utility model content
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, provides a kind of retaining cash effective, safe and reliable comprehensive mechanical coal mining large inclination working surface hydraulic support walkway retaining cash device.
For achieving the above object, the technical solution used in the present invention is as follows:
Comprehensive mechanical coal mining large inclination working surface hydraulic support walkway retaining cash device of the present utility model comprises retaining cash beam, retaining cash plate and retaining cash jack, and retaining cash beam upper end is connected with the hydraulic support back timber, and the lower end is provided with retaining cash plate; Retaining cash jack one end is connected with the hydraulic support back timber, and the other end is connected with retaining cash beam.
This retaining cash device also comprises retaining cash plate jack, and retaining cash plate jack upper end is connected with retaining cash beam upper end, and the other end is connected with retaining cash plate lower end, and the retaining cash plate other end is movable to be inserted in the retaining cash beam.
Retaining cash beam upper end is preferably hinged with the hydraulic support back timber.Retaining cash jack one end and hydraulic support back timber are preferably hinged, and the other end is hinged with retaining cash beam.
Because the utility model substitutes original artificial Curtain hanging device with retaining cash beam and retaining cash plate, the retaining cash is effective, safe and reliable; Adopt the angle of inclination of retaining cash jack control retaining cash plate in addition, adopt the vertical height of retaining cash plate jack control retaining cash plate, all-hydraulic automatic control reduces labour intensity.
Description of drawings
Fig. 1 is the large inclination working surface hydraulic support schematic diagram that the retaining cash device of prior art is housed;
Fig. 2 is the large inclination working surface hydraulic support schematic diagram that retaining cash device of the present utility model is housed.
The specific embodiment
As shown in the figure, comprehensive mechanical coal mining large inclination working surface hydraulic support walkway retaining cash device of the present utility model comprises retaining cash beam 3, retaining cash plate 4 and retaining cash jack 6, and retaining cash beam 3 upper ends and hydraulic support back timber 1 are hinged, and the lower end is provided with retaining cash plate 4; Retaining cash jack 6 one ends and hydraulic support back timber 1 are hinged, and the other end is hinged with retaining cash beam 3.
This retaining cash device also comprises retaining cash plate jack 5, and retaining cash plate jack 5 upper ends are connected with retaining cash beam 3 upper ends, and the other end is connected with retaining cash plate lower end, and retaining cash plate 4 one ends are movable to be inserted in the retaining cash beam 3.
In the manufacturing process, retaining cash jack 6 drives retaining cash beam 3 and retaining cash plate 4 to the operating position under the effect of hydraulic power, and retaining cash plate jack 5 can realize keeping off the flexible of cash plate 4.Whole process is easy to install, saves the labour.
