The utility model discloses a ground pulley assembly capable of preventing the hands from being clamped. The ground pulley assembly comprises a pulley, a main body rack and a support frame, wherein a device for preventing the hands from being clamped is also arranged on the axle of the pulley, and comprises two slender anti-jump brackets and anti-jump blocks respectively arranged on the anti-jump brackets; one ends of the two anti-jump brackets are sheathed on the axle of the pulley by shaft sleeves, and the tops of the other ends of the anti-jump brackets are respectively provided with the anti-jump block; each anti-jump block is formed by two bases with semicircular structures and a hoop used for fixing the two bases with the semicircular structures together; after touching a cable, a worker is stopped by the anti-jump blocks and is not drawn into a sliding groove, so that personal injury is avoided. The safety of engineering operation is improved. The ground pulley assembly is suitable for any similar ground pulley, thus being wide in application prospect.
Description
Technical field
The utility model relates to a kind of used tool of petroleum exploration field, especially a kind of lower sheave assembly of finger.
Background technology
The Pulley of well logging use plays the weight of bearing cable and downhole instrument in during well logging, carries out the effect of cable guiding simultaneously, is when well logging one of indispensable cellar connection.Wherein lower sheave has been mainly the effect of cable guiding.Existing lower sheave is made up of pulley, main shaft, main frame and anti-hurdle race.When well logging, chain is fixed on lower sheave on drilling well crossbeam by the pulling shaft on lower sheave main frame.When wellhead cable is installed, first cable will pass through from the chute bottom of lower sheave, then upwards runs to top sheave.Extend downwardly into well head from the chute top of top sheave, connecting downhole instrument.In order to prevent cable job-hopping, anti-hurdle race is installed on lower sheave.When lower sheave is installed, the point of contact bearing of trend according to cable on lower sheave, installs anti-hurdle race with fixed angle.It can effectively protect cable to move at pulley groove.
When staff works at the limited drilling platform of activity space, may touch for some reason the cable of smooth operation, do not have the operating lower sheave of finger pinch device will moment by the hand that touches cable along with cable proceeds in pulley, the personnel that cause injure.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of and prevents that operating personal from, touching near lower sheave after the cable of operation, being brought into lower sheave by operating cable, thus the lower sheave assembly of the finger that the personnel that cause injure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of lower sheave assembly of finger, comprise pulley, main frame, bracing frame, on the wheel shaft of pulley, be also provided with finger pinch device, described finger pinch device comprises two elongated anti-jump supports and is arranged on anti-jump on anti-jump support, two anti-jump support one end are enclosed within by axle sleeve on the wheel shaft of pulley, other end top is equipped with respectively anti-jump, be enclosed within on the one end of two anti-jump supports in pulley axle and be provided with the circular arc through slot take pulley axle as the center of circle, two anti-jump supports can rotate by axle sleeve in pulley axle, and pass circular arc through slot by the screw rod being arranged on main frame, the relative position of two anti-jump supports is fixed and adjusted to the nut of screwing on, the anti-jump clip being fixed together by the base of two semi-circular structures with by the base of two semi-circular structures forms, when the base of two semi-circular structures is involutory together, be formed with therebetween the through hole that cable is passed through, on clip, corresponding through hole position arranges corresponding through hole.
Described base is connected by screw thread mode with clip, and clip is disc, is provided with the channel slot connecting with the through hole of clip, the passage that channel slot is installing cables in disc face.
Described anti-jump bulk matter is wear-resisting non-metallic material.
The beneficial effects of the utility model are: cable is by 2 on anti-jump support in lower sheave anti-jump top sheaves that rerun.Staff touches and also can be subject to anti-jump stop and can not be involved in chute after cable, has avoided life injury.Improve the safety of engineer operation.This finger pinch device is applicable in any similar lower sheave, and application prospect is extensive.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-5, the lower sheave assembly of finger of the present utility model, comprise pulley 1, main frame 2, bracing frame 5, on the wheel shaft of pulley 1, be also provided with finger pinch device, described finger pinch device comprises two elongated anti-jump supports 3 and is arranged on anti-jump 4 on anti-jump support 3, two anti-jump support 3 one end are enclosed within by axle sleeve 6 on the wheel shaft of pulley 1, other end top is equipped with respectively anti-jump 4, be enclosed within on the one end of two anti-jump supports 3 on pulley 1 wheel shaft and be provided with the circular arc through slot 7 take pulley 1 wheel shaft as the center of circle, two anti-jump supports 3 can rotate by axle sleeve 6 on pulley 1 wheel shaft, and pass circular arc through slot 7 by the screw rod 8 being arranged on main frame 2, the relative position of two anti-jump supports 3 is fixed and adjusted to the nut 9 of screwing on, formed by the base 11 of two semi-circular structures and clip 12 that the base of two semi-circular structures 11 is fixed together for anti-jump 4, when the base 11 of two semi-circular structures is involutory together, be formed with therebetween the through hole 13 that cable is passed through, on clip 12, the position of corresponding through hole 13 arranges corresponding through hole 14.
Described base 11 is connected by screw thread mode with clip 12, and clip 12 is disc, is provided with the channel slot 15 connecting with the through hole 14 of clip 12 in disc face, the passage that channel slot 15 is installing cables.
Described anti-jump 4 materials are wear-resisting non-metallic material.
When well logging, cable, first through anti-jump on the anti-jump support in bottom, then passes through from the chute bottom of lower sheave, upwards by anti-jump of the anti-jump support in top.Adjust anti-jump support angle, make anti-jump consistent with cable operation angle.Cable upwards continues to run until top sheave.Extend downwardly into well head from the chute top of top sheave, connecting downhole instrument.Anti-jump one side can effectively prevent that cable from altering groove, on the other hand because there is the existence of anti-jump, when staff works on the drilling platform of limited space, touch because of carelessness cable, the cable of operation takes staff to anti-jump when neighbouring, just stopped by anti-jump, can not be brought in pulley groove, the personnel that cause injure.In addition, due to anti-jump be to be made by wear-resisting non-metallic material, cable moves and can effectively prevent by anti-jump frictionally damage in anti-jump.This novel project organization has played the effect of finger well.
In sum, content of the present utility model is not limited in the above-described embodiment, knowledgeable people in same area can propose easily other embodiment within technical director's thought of the present utility model, but within this embodiment is included in scope of the present utility model.
