Abstract
The utility model discloses a positioning device used for replacing a main transmission shaft safety bolt. A platform moves along a guide rail through depended wheels and idler wheels. Lugs are arranged on two sides of the platform and fixed on the platform and the guide rail through locating pins. A jacking hydraulic cylinder and two guiding extensible rods are respectively arranged on the top face of the platform. An arc-shaped plate is arranged at the top ends of the jacking hydraulic cylinder and the two guiding extensible rods. Two turning wheels are arranged on the concave surface of the arc-shaped plate at intervals. The positioning device facilitates implementing replacement operation of the main transmission shaft safety bolt, improves quality of replacement of the safety bolt, avoids potential safety hazards of the replacement operation and ensures normal operation.
Description
Technical field
The utility model relates to a kind of positioner for changing the final drive shaft safety bolt.
Background technology
In order to realize the overload protection of main motor, usually adopt safety bolt to connect the final drive shaft of main motor catcher and frame in each rolling line.Both protect the overload of main motor, also avoided the super negative stressed of rolling middle equipment, thereby guaranteed the normal operation of motor and rolling equipment.When overhaul of the equipments, usually need to change safety bolt, due to the restriction that is subjected to production scene equipment and place, be generally tiltedly when adopting the driving lifting and hang, namely implement the safety bolt dismounting after the oblique final drive shaft of slinging, and the position is narrow, there is certain potential safety hazard in unfavorable personnel's operation.The dangerous bolt of general replacement one collateral needs about 60 minutes consuming time; and the quality that safety bolt is changed can't be protected; have influence on the assembly precision of final drive shaft reduction box, cause the gear engagement of reduction box and the jumping degree error of each backlash and axle, until shut down the normal production run of impact.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of positioner for changing the final drive shaft safety bolt, utilize the convenient replacing operation of implementing the final drive shaft safety bolt of this positioner, improved the quality that safety bolt is changed, avoid changing the potential safety hazard of operation, guaranteed the normal operation of equipment.
for solving the problems of the technologies described above, the positioner that the utility model is used for replacing final drive shaft safety bolt comprises guide rail, platform, jacking cylinder, arc, two guide extension bars, two ears are climbed, two alignment pins, two rollers, two runners and four rollers, described four rollers are located at respectively four jiaos, described platform, described platform is positioned at described guide rail top and described four rollers against the both sides of described guide rail, described two roller intervals are located between described platform and guide rail, described two ears are climbed and are located at respectively described platform both sides, described two alignment pins insert respectively described two ears and climb and the guide rail both sides, described jacking cylinder vertical center is located at described platform end face, described two guide extension bars are vertical at described platform end face and are positioned at described jacking cylinder both sides, described arc is located at described jacking cylinder and two guide extension masthead ends and arc top and is positioned at the jacking cylinder top, described two runners interval respectively are located at the concave surface of described arc.
The positioner that is used for replacing final drive shaft safety bolt due to the utility model has adopted technique scheme, the platform that is this positioner moves along guide rail by roller and roller, the platform both sides are provided with ear and climb and pass through alignment pin fixed platform and guide rail, the platform end face is respectively equipped with jacking cylinder and two guide extension bars, arc is located at jacking cylinder and two guide extension masthead ends, and the concave surface of arc is located at two runner intervals.The convenient replacing operation of implementing the final drive shaft safety bolt of this positioner has improved the quality that safety bolt is changed, and has avoided changing the potential safety hazard of operation, has guaranteed the normal operation of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation that the utility model is used to change the positioner of final drive shaft safety bolt.
The specific embodiment
as shown in Figure 1, the positioner that the utility model is used for replacing final drive shaft safety bolt comprises guide rail 1, platform 2, jacking cylinder 7, arc 9, two guide extension bars 6, two ears climb 4, two alignment pins 41, two rollers 5, two runners 8 and four rollers 3, described four rollers 3 are located at respectively 2 four jiaos, described platform, described platform 2 is positioned at described guide rail 1 top and described four rollers 3 against the both sides of described guide rail 1, described two roller 5 intervals are located between described platform 2 and guide rail 1, described two ears are climbed 4 and are located at respectively described platform 2 both sides, described two alignment pins 41 insert respectively described two ears and climb 4 and guide rail 1 both sides, described jacking cylinder 7 vertical centers are located at described platform 2 end faces, described two guide extension bars 6 are vertical at described platform 2 end faces and are positioned at described jacking cylinder 7 both sides, described arc 9 is located at described jacking cylinder 7 and two guide extension bar 6 tops and arc top and is positioned at jacking cylinder 7 tops, described two runners 8 interval respectively are located at the concave surface of described arc 9.
When changing the operation of final drive shaft safety bolt, this device moves to final drive shaft below by guide rail with platform, in the platform movement process, four rollers are along guide rail both sides rotation, played the position-limiting action of platform, and platform accurately moves to below final drive shaft platform sliding on two rollers, inserting by two alignment pins the corresponding through hole of through hole and guide rail both sides that platform two of both sides ear climbs this moment makes platform be fixed on guide rail, avoid the relative motion of platform and guide rail, guarantee the safety of operation; Start subsequently jacking cylinder, arc is under the pushing tow of jacking cylinder, and rise until lift the final drive shaft diameter of axle under the acting in conjunction of two guide extension bars, and final drive shaft is positioned on two runners of arc concave surface, when final drive shaft and main motor catcher maintains an equal level, make the final drive shaft screw corresponding with main motor catcher screw by the moving final drive shaft of two runner dishes of arc concave surface, can implement the replacing operation of safety bolt.
Use this positioner obviously to improve overhaul efficiency, work efficiency is original twice, and this positioning device structure is simple, and is reasonable in design, and volume is little, deposit take up space little, use efficient and conveniently, guaranteed the degree of balance of final drive shaft and the assembly precision of reduction box, the service life of having improved equipment, applied widely, can be used for the upkeep operation of all kinds of large-scale power transmission shafts.
