Kinematic pair P pair is formd when dynamic secondary R pair, 823 stretching motion of rotating hydraulic cylinder, rotating hydraulic cylinder 823 turns in No. four ear mounts 824
Kinematic pair R pair is formd when dynamic, so that four No. four ear mounts 824 of rotating hydraulic cylinder 823, four of No. three ear mounts 822, four
For four 4-RPR type parallel connection branches of parallel institution, annular roof plate 825 is the moving platform of parallel institution 82, and annular panel 821 is
The fixed platform of parallel institution 82 by fixed platform, four 4-RPR type parallel connection branches, moving platforms forms 44-RPR in the present invention
Type parallel institution 82,82 structure of 44-RPR type parallel machine is with stability is good, dynamic property is good, precision is high, rigidity is strong and bearing capacity
The advantages that big, annular roof plate 825 are mounted on accessory plate 83, and four parallel institutions 82 are simultaneously to the branch on accessory plate 83 when work
Support mechanism 84 is effectively supported, and simultaneously the supporting mechanism 84 in support device 8 works asynchronously, on supporting mechanism 84
Three supporting cylinders synchronous workings, three hydraulic cylinders distinguish vertically different motion according to construction location actual conditions,
Enable flexible material form bearing plate 85 be comprehensively tightly attached to construction location, it is ensured that bearing plate 85 can to construction location into
The effective supporting of row, the supporting mechanism 84 on accessory plate 83 work asynchronously, and according to different situations respectively into being adjusted, make load-bearing
Plate 85 realizes the function that gib automation is adjusted, solves existing tunnel bridge and build to the comprehensive supporting of construction location
If in gib construction process exist manually by the materials such as concrete and steelframe be processed into gib, consuming time is long, throwing
Enter it is big, influence project progress, the construction surface for different structure needed to build corresponding gib, labor intensity of workers is big,
It is complicated for operation, cannot reuse, the problems such as waste of resource and working efficiency are low, reached purpose.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and only illustrating for the description in above embodiments and description is of the invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these change and change
Into all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent
