Abstract

A kind of motor rapid adjustment and anti-theft device.Solve mainly that the motor adjustment is wasted time and energy and easily stolen problem.It is characterized in that: four jiaos are hinged with swinging axle (4) between chassis (1) and holder (3); rear end, chassis (1) is fixed with " L " shape adjustment rack (5); vertical rectangular opening on the stud (6) of adjustment rack (5) is built-in with adjusts bolt (7); bolt (7) is inner to link to each other with holder (3); connect the outer protective sleeve (9) that is with of hinged nut (8) between motor (2) and chassis (1) and holder (3); be equipped with jackscrew (10) respectively in protective sleeve (9) upper end and nut (8) the lower end radial hole; be filled with dried holiday in the outer stomidium of jackscrew (10), jackscrew (10) the inner of protective sleeve (9) upper end places in the annular groove (11) of the outer upper end of nut (8).This motor rapid adjustment and anti-theft device have the time saving and energy saving and antitheft characteristics of adjusting.

Description

Motor rapid adjustment and anti-theft device

Technical field:

The utility model relates to the used adjusting device of pumping-unit motor, especially motor rapid adjustment and anti-theft device in the oil recovery field, oil field.

Background technology:

In oil recovery field, oil field, power on the oil pumper is generally motor, motor adopts chute type to fix more, when adjusting the motor pulley parameter, and when changing motor belt, must unload on the lower railway many set bolts and motor jackscrew, with crowbar or sledgehammer mobile motor, after having assembled, with same manner motor is retracted original position more again, fastening bolt, the problem that waste time and energy with regard to existing like this, labor strength is big, and sometimes the workman for following the line of least resistance, the belt semi-mounted on belt pulley, use driven by motor, thereby cause security incident frequently to take place.In recent years simultaneously, motor and the stolen phenomenon of motor track are also relatively more serious, influence ordinary production.

The utility model content:

Waste time and energy and easily stolen deficiency in order to overcome existing motor adjustment, the utility model provides a kind of motor rapid adjustment and anti-theft device, and this motor rapid adjustment and anti-theft device have the time saving and energy saving and antitheft characteristics of adjusting.

The technical solution of the utility model is: this motor rapid adjustment and anti-theft device comprise the holder of chassis and fixed electrical machinery; four jiaos are hinged with swinging axle between chassis and holder; the extreme end of chassis is fixed with L shaped adjustment rack; vertical rectangular opening on the stud of adjustment rack is built-in with the adjustment bolt; adjusting bolt the inner links to each other with holder; the hinged nut that connects between motor and chassis and holder is with protective sleeve outward; be equipped with jackscrew respectively in protective sleeve upper end and the nut lower end radial hole; be filled with dried holiday in the outer stomidium of jackscrew; jackscrew the inner of protective sleeve upper end places in the annular groove of the outer upper end of nut, and the nut top axial has polygonal hole.

The beneficial effect that the utlity model has is: this motor rapid adjustment and anti-theft device are owing to adopted such scheme, adjust the purpose that bolt can be realized adjusting the motor belt parameter and change belt by rotation, thereby reach time saving and energy saving rapid adjustment motor belt parameter and change the belt purpose, eliminated potential safety hazard; Owing to outside the hinged nut that connects between motor and chassis and holder, be with protective sleeve, solve the generation of motor and the stolen phenomenon of motor track simultaneously, effectively reduced production costs, guaranteed ordinary production.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is structure cutaway views of nut 8 among Fig. 1.

1-chassis among the figure, 2-motor, 3-holder, 4-swinging axle, 5-adjustment rack, 6 studs, 7-bolt, 8-nut, 9-protective sleeve, 10-jackscrew, 11-annular groove, the polygonal hole of 12-.

Embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By Fig. 1 in conjunction with shown in Figure 2; this motor rapid adjustment and anti-theft device comprise the holder 3 of chassis 1 and fixed electrical machinery 2; chassis 1 and holder have swinging axle 4 by bolted splice up and down for 3 four jiaos; 1 rear end, chassis is fixed with L shaped adjustment rack 5; vertical rectangular opening on the stud 6 of adjustment rack 5 is built-in with adjusts bolt 7; bolt 7 the inners link to each other with holder 3; the hinged nut 8 outer protective sleeves 9 that are with that connect 3 of motor 2 and chassis 1 and holders; protective sleeve 9 upper ends and nut 8 lower end radial holes are built-in with jackscrew 10; be filled with dried holiday in the jackscrew 10 outer stomidiums; jackscrew 10 the inners of protective sleeve 9 upper ends place in the annular groove 11 of nut 8 outer upper ends, and the nut top axial has polygonal hole 12.

During actual the use, chassis 1 is welded on the support of oil pumper, when adjusting motor 2 belt pulley parameters or changing motor 2 belts, to adjust bolt 7 earlier and unclamp, at this moment holder 3 moves forward at the pulling swinging axle 4 of motor belt, at this moment can adjust motor 2 belt pulley parameters or change motor 2 belts, after adjusting motor 2 belt pulley parameters or changing motor 2 belts, bolt 7 is adjusted in reverse rotation once more, and bolt 7 pulling bottom moving axis 4 are upwards mobile backward with holder 3 adjusting, with tension on belt.Thereby realize time saving and energy saving rapid adjustment motor belt parameter and change the belt purpose, eliminated potential safety hazard; Simultaneously when motor 2 and chassis 1 are installed with holder 3; with in 8 four jiaos of holes of interior cubic spanner insertion nut 12 nut 8 being screwed on the screw rod; again jackscrew 10 is withstood on the screw rod; then protective sleeve 9 is enclosed within outside the nut 8; again jackscrew 10 is withstood in the annular groove 11 of the outer upper end of nut 8, at last with jackscrew 10 holes with dried holiday shutoff, thief can only rotate protective sleeve 9 when stealing like this; can't rotating nut 8, thus reach antitheft purpose.
