Technical field
The utility model relates to a kind of mining multi-core pipe sebific duct of coal mine fully-mechanized mining support apparatus, particularly a kind of hydraulic support.
Background technique
High-pressure rubber pipe is widely used in the machinery such as mine, metallurgy, chemical industry, and especially down-hole fully-mechanized mining equipment and engineering machinery are used more general.The all hydraulic pipeline of coal mine fully-mechanized mining and high-grade conventional mining support apparatus is made up of sebific duct and associated pipe auxiliary substantially.Mining hose is the important control channel of the adjacent frame control system of hydraulic support, and it connects the control chamber of this hydraulic support pilot valve active chamber and adjacent frame main valve selector valve.
Present sebific duct specifications and models are many, and use amount is very big, and the fault form of expression of sebific duct is also many, the reason complexity.In working surface and tunnel, the pressure duct that hundreds of rice is long, exposed, any fault all may increase potential safety hazard, and fault will directly cause working surface to be shut down, and influence manufacturing efficiency, increase maintenance cost; In addition, under rugged environment, change sebific duct, inevitable contaminated system, the potential faults of other links of increase system reduces the reliability and the efficient of whole hydraulic system.And down-hole actual conditions environment is more abominable, complex circuit, a large amount of sebific ducts messy unordered, take up room big, the inconvenience management.
The model utility content
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides good, the easy and simple to handle hydraulic support of a kind of core pipe safety protection mining multi-core pipe sebific duct.
Technical solution of the present utility model is: mining multi-core pipe sebific duct comprises positioning disk, chuck, tail joint, fixed cover, screw thread cutting ferrule, rapid pipe joint, core pipe assembly, locating stud and hose assembly; The core pipe assembly is arranged in the hose assembly in order; Positioning disk is fixedlyed connected by locating stud with chuck; Positioning disk, chuck, fixed cover and screw thread cutting ferrule are fixed on the sebific duct two ends in order with the core pipe end; Positioning disk and chuck restriction core pipe assembly up and down and about move, fixed cover moves Vertical direction fixed core pipe assembly; Cover tail joint in the screw thread cutting ferrule; Rapid pipe joint is enclosed within outside the screw thread cutting ferrule, and rapid pipe joint is connected multi-core pipe sebific duct two ends with the joint of hydraulic bracket system.
The quantity of described core pipe assembly is 6～24.
The lower end of described tail joint connects an elbow assembly by the draw-in groove form.
The rated pressure of described core pipe assembly is greater than 60Mp, and booster pressure is greater than 120Mp.
The utility model advantage compared with prior art is:
(1) mining multi-core pipe sebific duct is installed between the control chamber of the pilot valve of hydraulic support and main valve selector valve, reaches to link up pilot valve active chamber and selector valve control chamber.Selector valve and then control set corresponding action by every little core management and control system correspondence.Mining multi-core pipe sebific duct of the present utility model is that many core pipes are contained in the sebific duct, and the effect of the little core glue of protection is played with big sebific duct parcel in the outside, greatly reduces the damage of down-hole actual environment to the core pipe.
(2) the core pipe of mining multi-core pipe sebific duct of the present utility model, what all adopt is high pressure core pipe, rated pressure reaches 60Mp, and booster pressure is up to 120Mp.The normally used emulsified liquid pressure of support apparatus is 31.5Mp under the coal mine, and this mining multi-core pipe sebific duct can reach the down-hole high pressure usage requirement fully.
(3) because there are fixing device and positioning device in sebific duct of the present utility model two ends, improve installation efficiency, accomplished every core pipe plug-in mounting simultaneously, simple to operation.
(4) sebific duct of the present utility model integrates many little core pipes, according to arranging in proper order, thereby save space and sebific duct and avoid messy unordered, the actual conditions environment is more abominable in the down-hole, the core pipe of this multi-core pipe is to be contained in the sebific duct the inside, has avoided the phenomenon that pipeline is scattered, inconvenience is managed.
Description of drawings
Fig. 1 is the schematic representation of the mining multi-core pipe sebific duct of the utility model;
Fig. 2 is the plan view of the mining multi-core pipe sebific duct of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, mining multi-core pipe sebific duct of the present utility model comprises positioning disk 1, chuck 2, tail joint 3, fixed cover 4, screw thread cutting ferrule 6, rapid pipe joint 7, core pipe assembly 8, locating stud 9 and hose assembly 10.
Core pipe assembly 8 is arranged in the hose assembly 10 in order, and the positioning disk 1 at sebific duct two ends, chuck 2, fixed cover 4 and screw thread cutting ferrule 6 are fixed on the sebific duct two ends in order with the core pipe end.Positioning disk 1 is fixedlyed connected by locating stud 9 with chuck 2; Positioning disk 1 and chuck 2 restriction core pipe assemblies 8 about and about move, fixed cover 4 is mobile Vertical direction fixed core pipe assembly 8.Cover tail joint 3 in the screw thread cutting ferrule 6; Rapid pipe joint 7 is enclosed within outside the screw thread cutting ferrule 6; Rapid pipe joint 7 is connected multi-core pipe sebific duct two ends with the joint of hydraulic bracket system, position with positioning screwn during connection, to determine the conformity of every core pipe assembly 8 orders, thereby allow pilot valve active chamber and selector valve control chamber, corresponding one by one by core pipe assembly 8, make each pilot valve control corresponding selector valve.
