Abstract
The utility model relates to an adjustable device for a limit switch of a backup arm of a lithology density logging tool used for controlling the expanding and contracting of the backup arm of the lithyology density tool to be in place timely, reducing the troublesome methods for disassembling devices and solving the problems of easy damage of the devices. The utility model adopts the technical scheme that a groove is arranged at the corresponding position of the center of both ends of a fixed bottom plate so as to lead the limit switch to move conveniently in the groove, the limit space of the limit switch is adjusted to a greater extent, a limit reed can be timely in contact or connection with a top ring of a transmission screw switch, and the action of the limit switch is in place timely. The adjustable device has low modification cost and strong practicability, is beneficial to filed popularization and has potential application prospects in respects of improving the maintenance quality of the tool and the time efficiency.
Description
Technical field
The utility model relates to a kind of litho-density tool device backup arm limit switch tunable arrangement; be used to control the position limitation protection that lithology and density logging instrument backup arm opens, draws in mechanical trip, belong to the structure of modification of logger in the petroleum industry geophysical exploration technology.
Background technology
At present, the litho-density tool device all is the instrument that the well arm is pasted in the band backup, and what backup arm opened, draws in is angle-controlled in the control of stop switch reed and turn-screw switch dome loop contacts path size.Excessive when former limit switch stroke, make and position-limiting spring leaf and turn-screw switch dome loop contacts overlong time cause backup arm to draw tension in; Or position-limiting spring leaf do not contact with turn-screw switch apical ring, forces turn-screw still in overload operation, easily causes pulling force excessive and break leading screw or mechanically deform.In the actual production, only open former limit switch device after, regulate turn-screw switch apical ring and change limit switch and turn-screw contactinterval.Former limit switch is to join with fixed base plate; and at the fixing circular hole of two limit switches of a distance, base plate position design; join with screw fixed limit switch and instrument; spacing stroke is 2.5 centimetres; as shown in Figure 1, suitably regulate turn-screw switch dome ring position, connect when turn-screw switch apical ring and spacing left reed or right reed contact point bump; limit switch work (separate or merge) reaches the control to gathering of instrument backup arm or opening angle.Spacing stroke is the spacing of switch apical ring and position-limiting spring leaf left side contact point to the right side contact point.Because limit switch and turn-screw switch apical ring all are installed in instrument internal, and instrument skeleton space is less, frame for movement connects compact, connecting line is too much, cause the by-pass cock apical ring to move difficulty, simultaneously limit switch in the maintenance process is changed part, connecting line welding, device dismounting and installation and brought inconvenient difficulty.Thereby influenced the maintenance timeliness of instrument; Backup arm taking place again easily draw tension in or open problems such as excessive, limit switch evil idea, cause the instrument corresponding failure to increase, has influenced instrument logging quality and service efficiency.
Summary of the invention
The purpose of this utility model is the fixed installation and the suitable adjustable of litho-density tool device backup arm stop switch are improved, a kind of litho-density tool device backup arm limit switch tunable arrangement of architecture advances is provided, guarantees that the instrument backup arm draws in and opens accurately and put in place.
The utility model adopts following technical scheme, be that a kind of litho-density tool device backup arm limit switch tunable arrangement is made of the fixed base plate, limit switch, turn-screw, switch apical ring, screw, spacing right reed, the spacing left reed that connect shell, limit switch is installed on the fixed base plate, left and right sides position-limiting spring leaf is fixed on the limit switch by screw, the switch apical ring is arranged on the turn-screw, it is characterized in that having two stopper slots on the correspondence position of center, fixed base plate two ends.
This spacing flute length be 8 millimeters, wide be 3 millimeters, the stopper slot terminal is the round edge limited mouth, opening is rectangular flat mouthful, its spacing stroke is widened 8 millimeters in the same way by original 2.5 centimetres.
Limit switch can be convenient mobile in this groove, strengthen largely and regulate the spacing spacing of limitation travel switch, promptly increase or reduce the stroke of position-limiting spring leaf and switch dome loop contacts, make spacing left reed or right reed in time bump and connect turn-screw switch apical ring, reach the limit switch action and be in time.
The beneficial effects of the utility model are to be in time, conveniently to adjust the limit switch path, reduce the cumbersome approaches of dismantling device and the problem that easily causes device failure, this apparatus structure and manufacturing process are simple, safe and reliable, debugging is easy, device adopts adjustable frame for movement, convenient disassembly, dependable performance, highly sensitive.

The specific embodiment
Below in conjunction with Fig. 3 and Fig. 4 and embodiment structure of the present utility model is further specified, litho-density tool device backup arm limit switch tunable arrangement of the present utility model is by the fixed base plate 7 that connects shell, limit switch 3, turn-screw 1, switch apical ring 6, screw, spacing left reed 2, spacing right reed 5 constitutes, limit switch 3 is installed on the fixed base plate 7, a left side, the right limit reed is fixed on the limit switch 3 by screw, switch apical ring 6 is arranged on the turn-screw 1, it is characterized in that having two stopper slots 8 on the correspondence position of center, fixed base plate 7 two ends.
This spacing flute length be 8 millimeters, wide be 3 millimeters; The stopper slot terminal is the round edge limited mouth, and opening is rectangular flat mouthful.
The utility model improvement cost is low, and is practical.Help on-the-spot the popularization, providing powerful technical support aspect raising apparatus guarantee quality and the timeliness, have great application prospect simultaneously.
