Abstract
The utility model discloses a sliding block copper bush installing and clamping device which comprises a semicircular fixing device, an adjustment jackscrew and a soft steel cable load-carrying plate. The soft steel cable load-carrying plate is connected with the semicircular fixing device through the adjustment jackscrew and an adjustment jackscrew seat; two sides of the semicircular fixing device are respectively provided with soft steel cable guide sliding wheels and soft steel cable anti-disengaging guide grooves; a jackscrew adjustment rod inserting hole and a soft steel cable adjustment fixing screw are arranged on the soft steel cable load-carrying plate. The sliding block copper bush installing and clamping device strengthens operation safety, shortens the well stopping time of an oil well, reduces loss of crude oil, guarantees normal operations of equipment and reduces labor cost and cost consumption of materials. Compared with the prior art, the sliding block copper bush installing and clamping device has the advantages of being time-saving and labor-saving in operation, convenient to install and the like.
Description
Technical field
The utility model relates to the maintenance of petroleum industry chain drive pumping unit servicing unit, particularly slide block copper sheathing the instrument of using of changing is installed.
Background technology
The chain drive pumping unit of petroleum industry is in the production run process, and its slide block copper sheathing occurs damaging through regular meeting, must change.Because slide block is very little with the gap between the sliding thick stick, because opening copper sheathing diameter greater than sliding thick stick diameter, therefore is difficult to insert in the narrow and small slit smoothly goes, needs use the crude iron silk with the copper sheathing tighten usually during replacing, and be aided with external force and just can finish.The easy so local modification of copper sheathing that causes causes damage, reduces the application life of copper sheathing, prolongs the set-up time, not only influences oil well output but also increase maintenance difficulty, workload and cost.
The utility model content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and provides a kind of simple in structure, easy to operate, safe and reliable slide block copper sheathing that fastener is installed.
The utility model is taked following technical measures: a kind of slide block copper sheathing is installed fastener, comprise semi-circular, regulate jackscrew, bowden cable stressed plate, described bowden cable stressed plate links together by regulating jackscrew and adjusting jackscrew seat and semi-circular, described semi-circular both sides are provided with the bowden cable leading block, and the bowden cable stressed plate is provided with jackscrew adjusting rod jack and bowden cable is adjusted fixed screw.
Described semi-circular both sides also are provided with bowden cable anticreep gathering sill, are used with the bowden cable leading block.
The beneficial effects of the utility model are the safeties that strengthened operation, have shortened stopping the well time of oil well, have reduced the crude oil loss, have guaranteed the normal operation of equipment, have reduced labour cost and material cost consumption.Compared with prior art, have the operation time saving and energy saving, be convenient to advantages such as installation.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of slide block copper sheathing is installed fastener, comprise semi-circular 1, regulate jackscrew 2, bowden cable stressed plate 4, described bowden cable stressed plate 4 links together with semi-circular 1 by regulating jackscrew 2 and regulating jackscrew seat 3, described semi-circular 1 both sides are provided with bowden cable leading block 5 and bowden cable anticreep gathering sill 6, and bowden cable stressed plate 4 is provided with jackscrew adjusting rod jack 7 and bowden cable is adjusted fixed screw 8.
When copper sheathing is installed at the scene, at first copper sheathing 10 is installed on the sliding thick stick 11, again semi-circular 1 is stuck on the copper sheathing 10, then with bowden cable 9 bifilar being wrapped on the copper sheathing 10, by being fixed on the stressed plate 4 behind anticreep gathering sill 6 and the leading block 5, after adjusting fixed screw 8 and making bowden cable 9 stressed, to add draft control lever again inserts to screw in the adjusting rod jack 7 and adjusts jackscrew 2 bowden cable 9 is tightened up, make copper sheathing 10 and sliding thick stick 11 coincide seamless in the gap that can be installed into slide block and sliding thick stick 11 smoothly till, under the effect of slight external force, copper sheathing 10 is in place.At last, unload the utility model, more change jobs and finish, oil pumper can run well.
The utility model is not limited to the above specific embodiment, and every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention belong to scope of protecting of the present utility model equally.
