Description

The handwheel lifting gear of drilling fluid vibrating sieve

Technical field

The utility model relates to a kind of lifting gear, is specifically related to the handwheel lifting gear of drilling fluid vibrating sieve.

Background technology

Drilling fluid vibrating sieve is the one-level solid control equipment in drilling mud solid control system, process from shaft bottom and return mud the solid phase particles more than 85 μ m that starch, the major function of drilling fluid vibrating sieve is to separate solid phase particles in drilling fluid, lifting gear is one of important component part of vibrosieve, thereby its Main Function is to regulate the inclination angle of screen box to reach the inclination angle of adjusting sifting bed, realizes and control the long object of the stream of drilling fluid on sifting bed.The sifting bed lifting gear of existing drilling fluid vibrating sieve, ubiquity complex structure, large, the inconvenient operation of taking up room and adjust the defect highly inconsistent, degree of regulation is not high, and handwheel easily skids while regulating with handwheel.

Utility model content

Problem to be solved in the utility model is the sifting bed lifting device structure complexity of existing drilling fluid vibrating sieve, the problem of inconvenient operation.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of vibrosieve handwheel lifting gear, comprise turning cylinder and a left side that is symmetricly set on described turning cylinder two ends, right elevating mechanism, a described left side, right elevating mechanism comprises respectively handwheel and screw elevator, described screw elevator is connected with described turning cylinder by shaft coupling, described screw elevator comprises casing and is sleeved on the bolt jointing part in described casing, in described casing, be provided with Worm and worm-wheel gearing, described Worm and worm-wheel gearing comprises the worm screw of horizontal direction and the worm gear being connected with described worm engaging.

In technique scheme, described worm screw two ends are stretched out casing and are formed outside connecting portion and inner side connecting portion, described outside connecting portion and described handwheel adopt key connecting, and the outside of described handwheel is fixed with handwheel end cap, and described inner side connecting portion and described shaft coupling adopt key connecting.

In technique scheme, described worm gear center has internal thread through hole, described screw sleeve is contained in described internal thread through hole and with described worm gear and forms thread transmission, the top of described screw rod is fixed with flange, on described flange, have multiple tapped through holes, on the end face of described casing, be also provided with positioning sleeve, described screw rod is installed in described positioning sleeve from top to bottom.

In technique scheme, the outer rim of described handwheel is interval with projection and pit, and described handwheel end cap periphery is uniformly distributed multiple triangle grooves, and the outside of each described triangle groove rear end has a through hole.

The utility model, because connect by shaft coupling between turning cylinder and screw elevator, the inner Worm Wheel System that adopts of screw elevator, compact conformation, volume are little, because Worm and worm-wheel gearing has the advantage of self-locking, have ensured that vibrosieve keeps screen box inclination angle constant under normal operation again, realize and control the long object of the stream of drilling fluid on sifting bed, adjusting screw(rod) separately, realizes fine setting, and degree of regulation is high, simple in structure, good looking appearance, easy to operate, there is good practicality.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the isometric view of the utility model screw elevator;

Fig. 3 is the utility model screw elevator and screen box catenation principle figure.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in detail.

As depicted in figs. 1 and 2, the handwheel lifting gear of the drilling fluid vibrating sieve that the utility model provides, comprises turning cylinder 4 and the left and right elevating mechanism that is symmetricly set on turning cylinder 4 two ends.

Left and right elevating mechanism comprises respectively handwheel 1 and screw elevator 2, screw elevator 2 is made up of screw rod 27, casing 21 and the Worm and worm-wheel gearing that is arranged in casing 21, worm screw 23 two ends are stretched out casing 21 and are formed outside connecting portion and two connecting portions of inner side connecting portion, on the connecting portion of outside, offer keyway, between handwheel 1 and screw elevator 2, connect by the flat key being arranged on the connecting portion of outside, simple in structure, between inner side connecting portion and turning cylinder 4, connect by flat key box coupling 3, make it jointly to rotate with transmitting torque, transmission accuracy is high.

Worm gear 22 centers have internal thread through hole, screw rod 27 is sleeved in internal thread through hole and with worm gear 22 and forms thread transmission, the top of screw rod 27 is fixed with flange 25, on flange 25, have four tapped through holes 26, on the end face of casing 21, be fixed with positioning sleeve 24, screw rod 27 is installed in positioning sleeve 24 from top to bottom.

As shown in Figure 3, the top of flange 25 is provided with spring mechanism, spring mechanism comprises that upper spring backing plate 72, lower spring backing plate 71 and centre bore are stuck in the spring 73 of upper and lower spring backing plate raised position, upper spring backing plate 72 and screen box are bolted, lower spring backing plate 71 and flange 25 are bolted, because spring 73 external surfaces are quality of rubber materials, while regulating height, with frictional force between bossing is not enough to drive the rotation of upper spring backing plate, can only move up and down.

Again referring to Fig. 1, the outer rim of handwheel 1 is interval with projection and pit, in rotating handwheel, can increase friction, prevent that hand from skidding, the center of handwheel 1 has through hole, the outer face of outside connecting portion is provided with screwed hole of centre, and outside connecting portion is set with upper handwheel end cap 5 after passing the through hole on handwheel 1, and fixing with bolt 6.The periphery of handwheel end cap 5 is uniformly distributed 8 triangle grooves, and the top rounding arc angle of triangle groove is also pointed to handwheel end cap 5, rear end indent certain radian, and outside, each triangle groove rear end has a through hole.

The using method of the vibrosieve handwheel lifting gear that the utility model provides is as follows:

In the time that vibrosieve needs to adjust screen box inclination angle down in working order, grasp handwheel outer rim, rotate the handwheel 1 of one end, horizontal direction worm screw 23 is rotated, and by passing through flat key box coupling 3 transmitting torques, drive turning cylinder 4 both sides worm gears 22 to rotate, worm gear 22 rotates and drives on screw rod 27, lower movement, make whole lifting gear increase or decline, because Worm and worm-wheel gearing has the advantage of self-locking, ensure that vibrosieve keeps screen box inclination angle constant under normal operation, thereby by regulating the inclination angle of screen box to reach the inclination angle of adjusting sifting bed, realize and control the long object of the stream of drilling fluid on sifting bed, if if user is more tired with hand rotation handwheel for a long time, the triangle groove of stopping on wheel can also tramp with one's feet, control the rotation of handwheel.

When vibrosieve is during in stopped status, regulate separately the screw rod 22 of one end, can change the height of one-sided screen box, can realize fine adjustment function, can avoid occurring drilling fluid bias current on oscillating screen and run advantages such as losing phenomenon.

This apparatus structure is simple, and good looking appearance is easy to operate, is not easy to damage, and long service life, has good practicality.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
