Description
Technical field
The utility model belongs to the main control valve system of colliery bracket control system, particularly a kind of adjacent frame system of manual guide that is used for the control of hydraulic support main valve.
Background technology
Manually the adjacent frame system of guide is a most crucial control system in the hydraulic support hydraulic control system.Be mainly used in control and respectively carry out oil cylinder to hydraulic support hydraulic power is provided, realize every protective function of hydraulic support.The main valve control system of using mainly contains electrohydraulic control system and Direct Action Type manual control system at present, and electrohydraulic control system is mainly used in the hydraulic prop control of high seam; The Direct Action Type manual control system is mainly used in girdle or the control of economical hydraulic prop.
Though the control system of these two kinds of forms can satisfy actual needs substantially, also have following problem: (1) generally is used for the supporting control of high seam because electrohydraulic control system costs an arm and a leg, and is used for girdle, and cost is higher.(2) the Direct Action Type manual control system is owing to be that handle is directly controlled valve core of main valve, and the operational torque that needs is big, and the operator is tired easily in the operating process.(3) because the operation of hydraulic prop equipment must be neighboring frame-operated, so the main valve of Direct Action Type manual control system must be installed in adjacent frame, and this has determined that the fluid pressure line of whole system is many, and the pipeline complexity.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of integrated degree height, simple to operate, laborsaving, hydraulic control system cheaply are provided.
Technical solution of the present utility model is: the adjacent frame control system of manual guide comprises the main valve group and the manual guide's Control Component that are connected by multi-core pipe; Wherein the main valve group comprises main valve body and spool; Manually guide's Control Component comprises manual pilot valve and fluid proportion plate; Multi-core pipe comprises positioning disk, chuck, tail joint, fixed cover, screw thread cutting ferrule, snap joint, core pipe assembly, alignment pin and hose assembly; The core pipe end of core pipe assembly is arranged in the tail joint in order; Place chuck and positioning disk on the fixed cover; Positioning disk is fixedlyed connected by alignment pin with chuck, and is placed on the port part of tail joint; Moving up and down of positioning disk and chuck restriction core pipe assembly, the move left and right of fixed cover restriction core pipe assembly; Cover tail joint in the screw thread cutting ferrule; Snap joint is enclosed within outside the screw thread cutting ferrule; Snap joint is connected multi-core pipe sebific duct two ends respectively with the joint of manual guide's Control Component and main valve group, make pilot valve working chamber and reversal valve control chamber corresponding one by one by the core pipe assembly.
When being connected the multi-core pipe two ends respectively with the joint of manual guide's Control Component and main valve group, described snap joint positions with dog screw.
The utility model beneficial effect compared with prior art is:
(1) integrated degree height.The utility model is owing to adopted the multi-core pipe technology, the main valve group and manually guide's Control Component can be installed in respectively on this and the adjacent frame, the main valve group is connected by multi-core pipe with manual guide's Control Component, manually pilot valve, multi-core pipe, valve core of main valve are corresponding one by one, only need operate in the operating process the pilot valve on guide's Control Component of adjacent frame, control liquid reaches the control to the main valve group by spool corresponding in the arrival main valve group of multi-core pipe.So just reached and used a multi-core pipe to replace the purpose of many pipes, made the integrated degree of whole system obviously improve.
(2) simple to operate, laborsaving.Because only need operate pilot valve, operational torque is very little, so the operator can be more laborsaving in operating process, make the utility model hommization more in operating process.
(3) cost is low.Because whole system all is pure hydraulic control, saved automatically controlled part, so the cost of whole system is also lower, is adapted at using in girdle and the economical hydraulic prop equipment.
Description of drawings
Accompanying drawing 1 is a schematic diagram of the present utility model;
Accompanying drawing 2 is a schematic diagram of the present utility model;
Accompanying drawing 3 is a multi-core pipe schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, manually the adjacent frame control system of guide comprises main valve group 1, multi-core pipe 2, manual guide's Control Component 3.Wherein main valve group 1 comprises main valve body and spool; Manually guide's Control Component 3 comprises manual pilot valve and fluid proportion plate.Manually guide's Control Component 3 is connected by multi-core pipe 2 with main valve group 1.
As shown in Figure 3, multi-core pipe 2 comprises positioning disk 21, chuck 22, tail joint 23, fixed cover 24, screw thread cutting ferrule 25, snap joint 26, core pipe assembly 27, alignment pin 28 and hose assembly 29.
The core pipe end of core pipe assembly 27 is arranged in the tail joint 23 in order by positioning disk 21, chuck 22 and fixed cover 24; Place chuck 22 and positioning disk 21 on the fixed cover 24; Positioning disk 21 is fixedlyed connected by alignment pin 28 with chuck 22, and is placed on the port part of tail joint 23; Positioning disk 21 moves up and down with chuck 22 restriction core pipe assemblies 27, the move left and right of fixed cover 24 restriction core pipe assemblies 27.Cover tail joint 23 in the screw thread cutting ferrule 25; Snap joint 26 is enclosed within outside the screw thread cutting ferrule 25.
This is the operating principle of the adjacent frame control system of guide manually: be schematic diagram of the present utility model as shown in Figure 1, above a row be the manual pilot valve of manual guide's Control Component 3, below one arrange and be the valve core of main valve of main valve group 1.By the manual pilot valve of operation two-position three way, promptly press lower handle K, the valve core of main valve work corresponding with it realizes providing hydraulic power to hydraulic prop equipment.After the execution architecture motion puts in place, put down handle K, the valve core of main valve corresponding with it then quits work.
