Embodiment
Fixed pulley 2 structures are: bottom plate 201, dividing plate 207 and upper mounted plate 202 are connected through connecting link 208; Respectively with in the chamber of dividing plate 207 two pulleys 206 are installed at bottom plate 201 and upper mounted plate 202; Pulley 206 centers are equipped with bearing 211; Bearing cap 203 is installed in the inboard of bottom plate 201, upper mounted plate 202 through screw rod 205, and interannulars are equipped with 210, two bearing 211 outsides of back-up ring in two bearings 211 has jump ring 209; Axis 212 passes bottom plate 201, dividing plate 207, pulley 206, bearing cap 203 and upper mounted plate 202, and axis 212 upper ends and nut 204 engagements;
Travelling block 5 structures are: two fixed heads 504 are connected through connecting rod 502 with vertical clapboard 508; Two 504 of fixed heads are equipped with two perpendicular pulleys 506; Perpendicular pulley 506 centers are equipped with vertical pivot and hold 510, two vertical pivots and hold 510 interior interannular and 509, two vertical pivots of guide ring are installed hold 510 outsides perpendicular jump ring 507 is arranged; Vertical pivot holds on 510 the outside fixed head 504 bearing gland 503 is installed; Axle 505 passes two fixed heads 504, perpendicular pulley 506, bearing gland 503, vertical clapboard 508, and axle 505 upper ends and big nut 511 engagements, is equipped with in fixed head 504 upper ends and colludes 501.
The utility model is through the use of pulley blocks; Effectively increase the measurement range that mechanical cabinet holds measuring instrument; And carry out architecture advances and solve the freezing easily broken problem of rope in winter; Pulley inner increase bearing and bearing cap make pulley dirigibility under the big environment of dust unaffected, reach the purpose of accurate measurement.Reduce the travelling block center of gravity through triangle fixed head structure; Make center of gravity be lower than the centre of gyration; Pulley roll over offset and twisted rope phenomenon appear in the effectively anti-limited slip wheel lifting process, therefore, and also can be even do not change the new type measuring instrument device through technological transformation; Drop into a small amount of manufacturing expense and reach the monitoring purpose, can seek the reduction of manufacturing cost.
The pulley blocks of design is that dynamic and static pulley is the sister block chip architecture voluntarily, singly colludes travelling block parts composition and comprises: pulley spindle, bilateral triangle fixed head, middle baffle plate, pulley sheet, bearing, bearing cap, suspension hook, limit shaft and axle sleeve, jump ring and securing member etc.
Travelling block adopts and singly colludes angle type fixed head sister block combined open structure.The design of triangle fixed head makes the pulley blocks center of gravity below the centre of gyration, makes one-piece construction firmly stable; 3 spacing fixing and central dividing plate designs can effectively limit rope and can not cause mutual winding and go out groove card rope phenomenon; The sister block sheet can satisfy the stroke needs; Pulley rotating mechanism adopts standard 206 bearings; Guarantee that the pulley sheet rotates flexibly, bearing adopts the spacing and one-sided tongue sealing of one-sided end cap seal jump ring spacing, and the sealing position limiting structure effectively protects bearing not corroded by rainwater and dust; Improve bearing serviceable life, the fixed position of stable bearing in pulley; Singly collude Open architecture sleet is passed through smoothly, on pulley, do not produce direct current accumulation formation and freeze, solved the freezing problem of pulley in winter.
Fixed pulley adopts
type fixed head sister block Open architecture.
type fixed head two ends perforate; Be prone to adopt screw to fix, also can adopt welding fixing.Other structure is identical with travelling block.
This pulley blocks design dismounting arbitrarily; In wire rope handling rope process, can the sheave segment part be taken apart, the rope that coiling is good is inserted in the corresponding pulley, can come into operation after reinstalling; Flexible being easy to safeguarded, makes our long distance that pulley blocks rope process is installed and obtained simplifying greatly.
Pulley spindle according to the dimensional data of pulley sheet, catch and back-up ring lengthening after, can expand to the pulley blocks of multiple combinations such as six, seven, eight, enlarge the usable range of pulley blocks.
The gas chamber piston links to each other with the magnetcisuspension float through rope pulley, 22.8 meters of throw of poston, and original system is single travelling block structure, the magnetcisuspension float should move 11.4 meters in the piston domain of walk, and existing measuring system range has only 6 meters, can't satisfy measurement requirement.According to the laborsaving characteristics of taking distance of travelling block; Adopt two travelling block pulley block structures; Piston walking same distance magnetcisuspension float displacement shortens to 50% of former displacement; Make to measure effective travel and expand and be twice, can satisfy 24 meters of piston walkings during 6 meters of magnetcisuspension float walkings, can satisfy the piston total travel fully and measure.
Improve and carry out emphasis: enlarge the effective range of magnetcisuspension float measuring mechanism, replace the sub-measurement range of original single-sheaved block mechanism's expansion suspension, make that the gas chamber energy storage is effectively enlarged through using homemade pulley blocks.
Practice condition and treatment Countermeasures: in order to reach the expansion measurement range, improve the stability of measuring mechanism, reduce the purpose of breakdown maintenance rate, decision is transformed to the drive disk assembly-pulley that mainly influences measurement effect.Modification scheme at first will solve measures the range problem, so original single-sheaved block changed into the pulley blocks of four pulleys; Next solves operation stability of equipment, changes the outer closure structure of pulley, adopts Open architecture.The pulley of outer closure structure receives freezing the influence greatly of sleet in winter; It is the main cause that pulley can not be run well; Adopt Open architecture that sleet is passed through smoothly; On pulley, do not produce direct current accumulation formation and freeze, solved the freezing problem of pulley in winter, in actual application, obtained confirmation.
