In chamber 34, and compression hydraulic cylinder 35 is additionally provided in clamping plate grafting chamber 34.One end of compression hydraulic cylinder 35 and support inserted link 14
The end of the inside of clamping plate grafting chamber 34 is hinged, the other end of compression hydraulic cylinder 35 then with the clamping plate inserting column 36 of ambulatory splint 32
Cavity ends are hinged.And then drive ambulatory splint 32 flexible using compression hydraulic cylinder 35, to pass through ambulatory splint 32 and rear side
Fixed baffle 31 is matched for clamping tightly, and supports inserted link 14 to lift the set cap 52 on support portion 29 to fix, consequently facilitating stretching
Contracting support arm 4 drives the modular bracket for entirely having dropped frame to rotate together, convenient transportation.
The two sides of the carrying cabinet 11 of bearer connection body 2 are separately provided for keeping balance, are conducive to retractable support arm 4
The support mechanism 6 of smooth rotation.Support mechanism 6 includes the support retracting cylinder 16 being vertically arranged, and support retracting cylinder 16 passes through support
Attachment base 15 is connected with the side of carrying cabinet 11.Support hydraulic cylinder 21, support hydraulic cylinder are provided in support retracting cylinder 16
The lower end of 21 one end and 16 inside of support retracting cylinder is hinged；Support hydraulic cylinder 21 reaches on the outside of 16 upper end of support retracting cylinder
The other end, then the middle part with support boots 22 is hinged.Support boots 22 are made of the body structure of rectangular-shape, 22 case of support boots
The both ends of body structure, the upside being in contact with back, are respectively arranged with supporting oblique surface；To increase support boots 22 and tunnel
Contact area between top plate, while reducing the top plate pressure that support mechanism 6 is born, the support stability of lifting device,
And it is conducive to the back condition that support mechanism 6 adapts to different condition.Also, using support hydraulic cylinder 21 in support retracting cylinder 16
Interior is flexible, and to drive support boots 22 to be in contact with top back, to enhance, retractable support arm 4 is flexible, rotates, and
Stability of equilibrium in lift unit formula stent procedures.
The bracket handling device in use, by bracket handling device 49 be arranged in every group of modular bracket of two framves centre,
In walking guide rail 1 in the middle part of tunnel, when needing the modular bracket by rear to move forward to the forefront of advance support section,
Firstly, stretching out the support hydraulic cylinder 21 of 2 two sides support mechanism 6 of bearer connection body, and then drive the support of 21 front end of support hydraulic cylinder
Top boots 22 be in contact with the top plate in top tunnel, with the balance of holding meanss two sides and support it is safe and reliable.Then, revolution is utilized
Mechanism 5 drive retractable support arm 4 to one group of modular bracket to be moved wherein any one frame bracket side rotation and make to stretch
Contracting support arm 4 and walking guide rail 1 are perpendicular, and are moved forward and backward bearer connection body 2, retractable support arm 4 is made to be located at set cap 52
Middle position (as shown in figure 17).Later, telescopic hydraulic cylinder 30 is stretched out, the support inserted link 14 of retractable support arm 4 is driven to stretch out,
Allow the underface lifting support portion 29 and being located in the middle part of set cap 52 of support 14 front end of inserted link；At this point, at compression hydraulic cylinder 35
In the state of stretching, it may be assumed that ambulatory splint 32 and fixed baffle 31 open, convenient for the placement (as shown in figure 18) of set cap 52.
Then, withdraw bracket lifting column 51, be gradually reduced set cap 52, also, when the downside of set cap 52 with
When lifting support portion 29 and being in contact of the support inserted link 14 of stretching drives ambulatory splint 32 to receive inwardly by compression hydraulic cylinder 35
It returns, so that being matched for clamping tightly by ambulatory splint 32 and rear side fixed baffle 31, supports inserted link 14 to lift support portion to fix
Set cap 52 on 29；Meanwhile continuing to withdraw bracket lifting column 51, allow bracket base 50 and the bottom in tunnel to divide completely
From in order to the subsequent rotation of bracket and transport (as shown in figure 19)；Disconnect this bracket into liquid back pipe road and carry out closure
Protection.Then, it withdraws support inserted link 14 and has dropped the modular bracket of frame thereon, then slowly rotate retractable support arm 4
Return the initial position parallel with walking guide rail 1；Later, it is utilized respectively and is connected with 13 lower part of extension sleeve tension connection otic placode 27
Chain tensioner 10, and the chain tensioner 10 being connected by pulley assembly 3 with the walking guide rail 1 of top, by flexible branch
