Further, described well surveying pulley, also comprises:
Support, described support is arranged on the both sides of described main frame by center shaft, prevent cable job-hopping by opening support.
Further, described well surveying pulley, also comprises:
Cleaning shoe assembly, described cleaning shoe assembly is arranged on main frame inside top, and near described wheel assembly top, for the mud on cable is cleared up.
Further, described cleaning shoe assembly comprises:
Cleaning shoe and fix screw, described cleaning shoe is fixedly connected with described main frame by described fix screw.
Further, described cleaning shoe bottom section is the right angle trigonometry shape of handstand.
Further, the diameter of described the first cell body is 0.8-1.1 rice, is applicable to the hard cable operation that diameter is less than or equal to 38mm.
Further, the diameter of described the second cell body is 0.8 meter, is applicable to the normal cable operation that diameter is less than or equal to 11.8mm.
The well surveying pulley that the utility model provides, by the first cell body and the second cell body are set on wheel assembly, the cable of any diameter all can be passed through smoothly, when the hank of cable also can be passed through together time smoothly by the cable assembly of different-diameter, can meet the different construction requirements of horizontal drainhole and inclined shaft well logging.
Accompanying drawing explanation
The structural representation of the well surveying pulley that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the lateral plan of well surveying pulley shown in Fig. 1;
Fig. 3 is the structural representation of I part in well surveying pulley structure shown in Fig. 2;
Structural representation when Fig. 4 is the medium-height trestle of well surveying pulley structure shown in Fig. 1 open mode.
The specific embodiment
Referring to Fig. 1-3, a kind of well surveying pulley that the utility model embodiment provides, comprises connector 1, main frame 7, support 6, cleaning shoe assembly 2, the wheel assembly 5 that is provided with the first cell body 5-1 and the second cell body 5-2 and suspension ring 8; Main frame 7 tops are by connector 1 and creep into group elevator equipment connection, and main frame 7 bottoms are connected with suspension ring 8; Wheel assembly 5 is arranged on the hollow part in the middle of main frame 7 by center shaft, and the first cell body 5-1 is arranged on the outer circumference surface of wheel assembly 5, and the diameter of the first cell body 5-1 is 0.8-1.1 rice, is applicable to the hard cable 3 that diameter is less than or equal to 38mm and moves.The preferred value of the first cell body 5-1 diameter is 1 meter, and cable can only bear sinuousness to a certain degree, when curvature hour, can reduce the service life of cable, and break-make decreasing insulating, in the time adopting the cell body of 1 rice diameter, cable can be not influenced, and service life and break-make insulating power are good.The second cell body 5-2 is arranged on the first cell body 5-1 bottom, and the diameter of the second cell body 5-2 is 0.8 meter, is applicable to the normal cable operation that diameter is less than or equal to 11.8mm.If necessary, can improve the diameter of two cell bodies.
At work, hard cable 3, first by pulley, as shown in Figure 4, in the course of the work, is opened the support on pulley 6 to both direction, make the free-running operation in the first cell body 5-1 under the protection of support 6 of hard cable 3.When in hard cable 3 lower going-into-wells of certain length, its latter linked normal cable 4, by pulley, moves in the second cell body 5-2 of pulley.By the first cell body 5-1 and the second cell body 5-2 are set on wheel assembly 5, make ￠ 11.8mm normal cable 4 when by pulley, keep stable, do not swing back and forth, the hard cable 3 that diameter is larger also can steadily pass through in the first cell body 5-1, does not occur the hidden danger such as job-hop.On hard cable 3 and normal cable 4, carry in process, hard cable 3 can be attached on the first cell body 5-1 and the second cell body 5-2 of pulley with the mud that normal cable 4 is brought from well, can remove the mud on the first cell body 5-1 and the second cell body 5-2 by cleaning shoe assembly 2.
The well surveying pulley that the utility model provides, its beneficial effect is as follows:
(1) by the first cell body and the second cell body are set on wheel assembly, the cable of any diameter all can be passed through smoothly, when the hank of cable also can be passed through together time smoothly by the cable assembly of different-diameter, can in pulley, not swing back and forth, can meet the different construction requirements of horizontal drainhole and inclined shaft well logging.
(2) by increasing cleaning shoe assembly, can carry out secondary cleaning to cable, the mud being attached on cable is scraped totally.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
