Description
Technical field
The utility model belongs to Construction Technology field, and in particular to one kind prevents tunnel lining trolley capping tunnel from encircleing
The device on top.
Background technology
When tunnel lining trolley positions in tunnel, since radian is inconsistent before and after the trolley formwork of two ends and worker grasps
It slips up, possible the phenomenon that occurring upper one group of lap-joint concrete capping, the shape at vault during trolley formwork jacking
Into " isolated island " type crackle, larger harm is generated to tunnel operation.
Utility model content
To avoid the generation of such mass defect, the utility model plan offer is a kind of to prevent platform based on tunnel lining trolley
Roof splits the device of tunnel vault.
For this purpose, technical solution is used by the utility model：A kind of device for preventing lining trolley capping tunnel-liner,
It is each to detect alarm unit packet including miniature transformer, three detection alarm units being arranged in parallel and a total alarm unit
Include normally closed manual switch, limit switch and the audible-visual annunciator being cascaded, each audible-visual annunciator and relay
Coils from parallel connection of coils is connected after the normally opened contact parallel connection of three relays with the coil of another audible-visual annunciator, a normally closed relay
Form total alarm unit, the normally-closed contact of the normally closed relay and a normally opened manual switch, one normally closed open manually
The control unit of lining trolley main oil pump motor is formed after pass, a fuse, an A.C. contactor series connection, three limitings are opened
Pass is separately mounted at the backform, left side mould and right side mould of formwork jumbo, and the contact distance corresponding position of three limit switches
3-the 8mm of formwork jumbo camber line at place.
Operation principle：Limit switch, one acousto-optic report of each limit switch series connection are installed respectively at backform and two side forms
Alert device, limit switch contact are higher than formwork jumbo 3-8mm of camber line, and when trolley formwork jacks in place, limit switch contact contact is mixed
Solidifying native face proves that trolley formwork fully supports to place, and limit switch is normally opened to be become to be closed, and connecting audible-visual annunciator i.e. can be certainly
Dynamic alarm.Vault contacted with any group of limit switch of abutment wall concrete surface all can automatic alarm, and can control respectively.After alarm
Lining trolley main oil pump motor is stopped, and operating personnel can not carry out operation of oil cylinde, by considered further that after manually observing whether
It needs to finely tune the flexible of oil cylinder, be needed if desired for finely tuning or carrying out next step operation of oil cylinde through the normally opened manual of control unit
Switch starts main oil pump.It can effectively avoid because concrete is destroyed caused by trolley jacking is excessive the phenomenon that by the device.
The beneficial effects of the utility model are：It can be loaded on existing lining trolley, when trolley formwork is jacked to appropriate
Position when alarm in advance, Oil pump electrical machinery is stopped, and prevents upper one group of lap-joint's concrete during trolley formwork jacking
Capping, it is ensured that subsequent tunnel operation security is reliable；Meanwhile three detection alarm units of the structure setting, respectively to backform, a left side
Side form and right side mould are monitored, and using the sequence progress for first operating jacking cylinder, operating left and right side mould oil cylinder again, it is ensured that
Lining trolley is in the optimum position in tunnel, and combines total alarm unit and alarm stopping operation of oil pump, it is ensured that in tunnel
It is not in capping phenomenon.
