Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of hydraulic support main control valve of the utility model breaks the extracting tool of spool, and as shown in Figure 1, comprise for the bracing or strutting arrangement of supporting post-rod 1 and the clamping device for mobile push rod 1, bracing or strutting arrangement is connected by gripper shoe 3 with clamping device.
Bracing or strutting arrangement comprises the support 4 of square table shape, the center of support 4 has through hole, the hole wall of through hole has screw thread, push rod 1 stretches in support 4 through through hole, and the edge of support 4 desktop is provided with the cuboid gripper shoe 3 with its vertical, and the one side of gripper shoe 3 is welded on support 4, the another side of gripper shoe 3 has rectangular recess 11, groove 11 is through with the thickness of slab of gripper shoe 3, and groove 11 is embedded with connecting axle 7, and connecting axle 7 is parallel with the interior concave plane of groove 11.
As shown in Figure 3, clamping device comprises alligator wrench 2, alligator wrench 2 comprises columned handle 9 and clamping device 10, handle 9 is hinged with clamping device 10, handle 9 is provided with the adjustment ball valve 8 for adjusting clamping device 10 openings of sizes with the junction of clamping device 10, handle 9 has the connecting hole 6 coordinated with connecting axle 7, connecting hole 6 is vertical and through along the handle body of handle 9.
Clamping device 10 is for clamping push rod 1.
Clamping device is connected with gripper shoe 3 with the cooperation of connecting axle 7 by connecting hole 6.The diameter of handle 9 is less than the length of connecting axle 7, and handle 9 can be made like this to move around on connecting axle 7.
Push rod 1 one end is curved suspension hook shape, and the other end of push rod 1 is welded with direct rod shape hand handle, hand handle is vertical with push rod 1.The shaft of push rod 1 is carved with screw thread and overlaps and have nut 5, nut 5 is fixed on support 4 by rivet.
The break using method of extracting tool of spool of a kind of hydraulic support main control valve of the utility model is, the structure of hydraulic support main control valve 12 as shown in Figure 4, this device is placed on hydraulic support main control valve 12, one end of suspension hook is had by push rod 1 to insert in hydraulic support main control valve 12 by circular hole b15, the suspension hook of push rod 1 acts on the disconnected spool 13 (structure of disconnected spool 13 as shown in Figure 5) in hydraulic support main control valve 12, disconnected spool 13 triggers through circular hole a14 by the suspension hook of push rod 1, regulate adjustment ball valve 8, push rod 1 is clamped by clamping device 10, handle 9 moves around in rotating shaft 7, handle 9 moves once along the screw thread back-out direction of push rod 1, push rod 1 will rise some distances from hydraulic support main control valve 12, now, regulate adjustment ball valve 8, clamping device 10 is made to unclamp push rod 1, then clamping device 10 is again by the grips of push rod 1 near support 4, handle 9 moves once along the screw thread back-out direction of push rod 1 again, push rod 1 will rise some distances from hydraulic support main control valve 12 again, the clamping device 10 that makes of repetition like this unclamps, clamping, until push rod 1 pulls out completely from hydraulic support main control valve 12, thus till taking out disconnected spool 13.
