Abstract
The utility model relates to a safe well logging pulley which comprises a shaft seat, a hanger shaft, a hanger shaft outer shell, a fixing plate, a pulley body, a pulley shaft, cylindrical roller bearings, a protection hood and another shaft seat. The pulley body is arranged in the protection hood, the outer edge of the pulley body corresponds to a rope guiding support which is fixed on the protection hood through the fixing plate, the pulley shaft sequentially penetrates through the pulley body, the fixing plate, and the protection hood from inside to outside, the two ends of the pulley shaft are fixed through nuts, the cylindrical roller bearings are arranged between the pulley body and the pulley shaft, the hanger shaft penetrates through the hanger shaft outer shell and the fixing plate and is fixed through a disc type nut, and the shaft seats are connected with the hanger shaft outer shell. The safe well logging pulley has the advantages of being simple in structure, convenient to install, and low in cost, a steel rope, a steel cable, a cable and the like are wound in sequence, the pulley body, the rope guiding support, the fixing plate and the protection hood together form a sealed space, the steel rope and the like are prevented from falling out of a pulley groove, other objects can not easily get involved in the pulley in the rotating process, and the safety coefficient is improved.
Description
Technical field
The utility model relates to a kind of safe well surveying pulley, relates in particular to the safe well surveying pulley of special guide piece 5700 that a kind of petroleum well logging cable for oil production and logging equipment is carried.
Background technology
Well surveying pulley is a kind of lifting guide piece that is applied to oil well logging.Be widely used in petroleum industry.But common well surveying pulley exists cable to drop out the risk of pulley groove, and cable is easily pulled off, and causes damage.If someone is on well surveying pulley side, also can cause injury to personnel, cable, in course of conveying, also has the risk that is involved in other article in addition.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide safe well surveying pulley, prevents that steel cable from dropping out pulley groove.
For achieving the above object, the utility model is achieved through the following technical solutions:
Safe well surveying pulley; comprise axle bed, hanging axis, hanging axis shell, adapter plate, pulley body, sheave shaft, cylindrical roller bearing, protective case, axle bed; in protective case, be provided with pulley body; pulley body outer is corresponding with rope guide rack; rope guide rack is fixed on protective case by adapter plate; sheave shaft is from inside to outside successively through pulley body, adapter plate, protective case; sheave shaft two ends are fixed by nut; between pulley body and sheave shaft, be provided with cylindrical roller bearing; hanging axis is through hanging axis shell and adapter plate; and fix by dish-shaped nut, axle bed is connected with hanging axis shell.
Pulley body outer is provided with pulley groove.
Axle bed is provided with bearing pin.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, easy for installation, cost is low; ensure that steel cable, wirerope, cable etc. reel in turn, by the enclosure space of pulley body, rope guide rack, adapter plate, the common composition of protective case, prevented that steel cable etc. from dropping out pulley groove; and in pulley rotary course, be difficult for being involved in other article, safety factor improves.

In figure: 1-bearing pin 2-axle bed 3-hanging axis 4-hanging axis shell 5-dish nut 6-adapter plate 7-pulley body 8-cylindrical roller bearing 9-sheave shaft 10-nut 11-protective case 12-rope guide rack.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, safe well surveying pulley, comprise axle bed 2, hanging axis 3, hanging axis shell 4, adapter plate 6, pulley body 7, sheave shaft 9, cylindrical roller bearing 8, protective case 11, axle bed 2, in protective case 11, be provided with pulley body 7, pulley body 7 outers are corresponding with rope guide rack 12, rope guide rack 12 is fixed on protective case 11 by adapter plate 6, pulley body 7 outers are provided with pulley groove, sheave shaft 9 is from inside to outside successively through pulley body 7, adapter plate 6, protective case 11, sheave shaft 9 two ends are fixing by nut 10, between pulley body 7 and sheave shaft 9, be provided with cylindrical roller bearing 8, hanging axis 3 is through hanging axis shell 4 and adapter plate 6, and fixing by fly nut 5, axle bed 2 is connected with hanging axis shell 4, axle bed 2 is provided with bearing pin 1.
In pulley body 7, pack two cylindrical roller bearings 8 into, and pack in plastic safety cover 11.Pack adapter plate 6 on the both sides of pulley, pass with sheave shaft 9, to connect plastic safety cover 11 and pulley body 7, and tighten fixing at sheave shaft 9 two ends with nut 10.On top,, be tightened with dish-shaped nut 5 through hanging axis shell 4 and adapter plate 6 with hanging axis 3.Again axle bed 2 is connected with hanging axis shell 4, bearing pin 1 is passed to axle bed 2.So just complete the assembling of safe well surveying pulley.When use, steel cable, wirerope, cable etc. are put into the pulley groove of pulley body 7 outers.
The utility model is simple in structure; easy for installation; cost is low; ensure that steel cable, wirerope, cable etc. reel in turn; by the enclosure space of the common composition of pulley body, rope guide rack, adapter plate, protective case, prevent that steel cable etc. from dropping out pulley groove, stop steel cable completely and dropped out pulley groove accident and occur; even operating personal operates near pulley, also there will not be accident.And in pulley rotary course, be difficult for being involved in other article, safety factor improves.
