Fig. 1 is the structure chart of existing hydraulic chock running valve group and nameplate mechanism thereof;
The structure chart of the nameplate mechanism of the hydraulic chock running valve group that Fig. 2 provides for the embodiment of the present invention; For ease of understanding, in figure, also show operating valve set;
Fig. 3 is the cross section view that draw-in groove put into by nameplate;
Fig. 4 is the cross section view that end cap puts into draw-in groove.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
The structure chart of the nameplate mechanism of the hydraulic chock running valve group that Fig. 2 provides for the embodiment of the present invention; Fig. 3 is the cross section view that draw-in groove put into by nameplate; Fig. 4 is the cross section view that end cap puts into draw-in groove; As shown in figs 2-4, the nameplate mechanism of this hydraulic chock running valve group can comprise: multiple nameplate 1 and draw-in groove 4, and draw-in groove 4 is arranged in the operating valve set of hydraulic support, and the quantity of multiple nameplate 1 is consistent with the quantity of monolithic control valve in operating valve set; Multiple nameplate 1 is arranged in draw-in groove 4, and with each monolithic control valve one_to_one corresponding, with the action sign of corresponding monolithic control valve on each nameplate 1, as " column rises column and falls " in Fig. 2, " passing stretch pass receive " and " main feed liquor master returns liquid " etc.
By being arranged to multiple nameplate 1 being used to indicate action separately, each nameplate 1 is placed in draw-in groove 4, when a certain action sign mistake, when not disassembling operating valve set, the replacing of each nameplate can be realized, all nameplates of operating valve set need not be changed, cost-saving, overall structure is simple, quick and easy for installation.
Preferably, the quantity of draw-in groove 4 is consistent with the quantity of monolithic control valve, and draw-in groove 4 one_to_one corresponding is arranged on each monolithic control valve.Particularly, each monolithic control valve is provided with two L shape clamps, 2, two L shape clamps 2 and is parallel to each other and interval predeterminable range, and the hollow space between two L shape clamps 2 forms draw-in groove 4.Further preferably, two L shape clamp 2 specular on monolithic control valve are arranged, so that firmly block nameplate 1.L shape clamp 2 can be welded on monolithic control valve, can certainly direct machine-shaping on monolithic control valve.Particularly, L shape clamp 2 can be welded on monolithic control valve by spot welded type, and in addition, L shape clamp 2 is welded on monolithic control valve in the horizontal direction, to avoid landing from draw-in groove 4 under the effect of own gravity.
