Description
Technical field
The present invention relates to a kind of oil drilling pump piston dismantling device, belong to oil drilling pump piston dismantling device technical field.
Background technology
In wellbore construction, because the solid concentrations such as landwaste in drilling fluid are high, or cylinder sleeve piston is long for service time, and the problem such as piston mass, leakage loss is bad and pitch brace is loose for cap to cause wellbore pump piston to sting, cause water on pump bad, pump pressure is unstable, affect the service efficiency of drilling pump, therefore need often to change piston assembly or glue core, fastening pull rod is for cap, the operational sequence of spot replace piston is: first laid down by valve case gland, take out valve wiper block, spring, valve, lay down pitch brace holding card, piston and pull bar take out by dish pump, ground on the scene pipe wrench, pitch brace pressure cap is laid down in two people's cooperations, take off old piston, load onto new piston, after tightening piston pressure cap, again cylinder sleeve is put in piston assembly, with crowbar, hammer heads in cylinder sleeve, tighten pitch brace holding card again, load valve, spring, wiper block, tighten valve case gland, complete and change piston operation.Need 3 people to coordinate during replacing, labour intensity greatly, the easily personnel that cause injures; Easily cause piston glue core and pitch brace screw thread to damage in advance during loading, shorten service time, increase replacement frequency; Many, the consuming time length of operational sequence, have impact on normally putting into operation of drilling pump, thus reduces wellbore construction timeliness.
Summary of the invention
The object of the invention is to overcome that the dismounting labour intensity existed in above-mentioned prior art is large, personnel's easily injured, defect such as piston glue core and pull bar leading screw is fragile, operational sequence is many, length consuming time, designing a kind of oil drilling pump piston dismantling device.
The present invention is become by righting gusset, leading screw, gusset set bolt, screw set head group.Righting gusset has center screw, and periphery has the screw corresponding with mud pump head; Threads of lead screw is arranged in the center screw of righting gusset, and its front end is the square joint having connecting hole, square joint can be distinguished installing sleeve nut, piston Tool for detaching and piston pressure cap.
The present invention uses the pullover and leading screw of leading screw by changing, and can realize piston steady fast assembling-disassembling and fastening on wellbore pump piston pull bar, thus simplification flow chart, improve operation timeliness, reduce labor intensity, effectively avoid the damage in advance of piston, realize safe and efficient production.

Detailed description of the invention
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, the present invention is made up of righting gusset 1, leading screw 2, gusset set bolt 3, leading screw pullover 4.Righting gusset 1 has center screw, and periphery has the screw corresponding with mud pump head 5; Leading screw 2 screw thread is arranged in the center screw of righting gusset 1, and its front end is the square joint having connecting hole, square joint can be distinguished installing sleeve nut 4a, piston Tool for detaching 4b and piston pressure cap 4c.
Sleeve nut 4a upper end cover has the cubic through hole 4a-1 with leading screw 2 front end square joint matched in clearance, and sleeve nut 4a inwall is processed with the spline 4a-2 coordinated for cap 6 with pitch brace.
Piston Tool for detaching 4b is made up of connecting rod 4b-2, dop 4b-3.Connecting rod 4b-2 front end is the square head cooperatively interacted with the square joint of leading screw 2 front end, and is connected with leading screw 2 front end square joint connecting hole by pin 4b-1, and connecting rod 4b-2 rear end is connected with dop 4b-3 by pin 4b-4.
Dop 4b-3 is U-shaped dop, is arranged on connecting rod 4b-2 rear end by bearing pin 4b-4.
Piston pressure cap 4c upper end cover has the cubic through hole 4c-1 with leading screw 2 front end square joint matched in clearance.
Leading screw 2 tail end is welded with sleeve pipe, can insert afterburning thick stick and drive screw turns.
After righting gusset 1 of the present invention is connected by gusset set bolt 3 with pump head 5, sleeve nut 4a and leading screw 2 front end square joint are connected and fixed, rotational lead screw 2, lays down pitch brace for cap 6; Take off sleeve nut 4a, change piston Tool for detaching 4b, the U-shaped dop 4b-3 on piston Tool for detaching 4b is stretched in piston 7 tie rod hole, rotary U-type dop 4b-3 is vertical with connecting rod 4b-2, is clamped on piston 7 tie rod hole, rotational lead screw 2, U-shaped dop 4b-3 pulls piston 7, is extracted; Take off piston Tool for detaching 4b, be arranged on the square joint of leading screw 2, rotational lead screw 2 by piston pressure cap 4c, the piston that need change heads into and in pitch brace hole pitch brace 8 screw thread being held level with both hands surely enter and need change; Sleeve nut 4a is arranged on leading screw square joint, then pitch brace is arranged on pitch brace 8 screw thread for cap 6, rotational lead screw 2, pitch brace is fastening for cap 6.
Using leading screw pullover 4 and leading screw 2 by changing, piston 7 steady fast assembling-disassembling and fastening on wellbore pump piston pull bar 8 can be realized, thus simplification flow chart, improve operation timeliness, reduce labor intensity, effectively avoid the damage in advance of piston, realize safe and efficient production.
