Specific embodiment

The utility model is further illustrated with reference to the accompanying drawings and detailed description:

As shown in figs. 1 to 6, a kind of tunnel form trolley vault grouting mouth automatic plugging apparatus, including grouting bucket ontology, institute It states grouting bucket ontology to adopt a split structure, including struggle against outside the mouth that is in the milk 1 and grouting mouth internal conflict 2,1 is struggled against outside the grouting mouth as half envelope Structure is closed, the top rotation connection on the top of bucket 1 and mouth internal conflict 2 of being in the milk outside the mouth that is in the milk, mouth internal conflict 2 of being in the milk corresponds to bucket outside the mouths that are in the milk The opening of 1 semi-closed structure, sides flexible connection driving mechanism 3 of the mouth internal conflict 2 far from bucket 1 outside grouting mouths of being in the milk, driving machine Structure 3 drives mouth internal conflict 2 of being in the milk to make rotary motion inside bucket 1 outside grouting mouths, and the driving mechanism 3 is hydraulic cylinder, the liquid 2 flexible connection of telescopic rod and the internal conflict of grouting mouth of compressing cylinder, the other end are articulated to oil cylinder back seat 4, and oil cylinder back seat 4 is fixed to On formwork jumbo.

Bucket 1 is fixedly installed in the position of formwork jumbo vault grouting mouth by fixed pin shaft 6 outside the grouting mouth.

The top of bucket 1 and the top of grouting mouth internal conflict 2 are by turning round the rotation connection of pin shaft 5 to Schaltisch outside the grouting mouth The position of vehicle vault grouting mouth.

As an embodiment, bucket 1 includes grouting mouth fixed frame 102 and grouting outside grouting mouth described in the present embodiment Mouth pipe 101, grouting mouth pipe 101 are built on grouting mouth fixed frame 102, and the side of grouting mouth pipe 101, which lays to be open, makes the mouth that is in the milk Pipe 101 is in semi-closed structure, and grouting mouth fixed frame 102 is installed on the position of formwork jumbo vault grouting mouth by fixed pin shaft 6； The grouting mouth internal conflict 2 includes grouting mouth internal conflict ontology 201, baffle 202 and oil cylinder front stall 203, and be in the milk mouth internal conflict ontology 201 Oil cylinder front stall 203 is laid in upper planar horizontal cloth baffled 202, the trailing flank of grouting mouth internal conflict ontology 201, and hydraulic cylinder stretches Bar and oil cylinder front stall 203 are flexibly connected.

When formwork jumbo is in vault grouting state, vault is in the milk, and mouth is in the open state, and driving mechanism 3 drives grouting mouth Rotary motion, i.e. the telescopic rod retraction of hydraulic cylinder are made in internal conflict 2 inside bucket 1 outside the mouths that are in the milk, and grouting mouth is left in grouting mouth internal conflict 2 The opening of 1 semi-closed structure of outer bucket, concrete opening of the semi-closed structure of bucket 1 outside grouting mouth enter formwork jumbo arch Vault filling concrete is realized on top；

When vault concrete is filled, stop pump concrete, the telescopic rod of hydraulic cylinder stretches out, and grouting mouth is pushed to conflict internally 2 make rotary motion inside bucket 1 outside grouting mouth around fulcrum post axis 5, until the telescopic rod of hydraulic cylinder is fully extended, in grouting mouth Bucket 2 moves to the opening for 1 semi-closed structure that struggles against outside the mouth that is in the milk, the semi-closed structure of bucket 1 and grouting mouth 2 structures of internal conflict outside the mouth that is in the milk Baffle 202 at closed space, mouth internal conflict 2 of being in the milk is concordant with the panel on formwork jumbo vault, realizes to vault grouting mouth Closure.

The embodiment of the above, the only preferred embodiment of the utility model not limit the utility model Practical range, therefore all equivalent change or modifications done according to structure, feature and principle described in the utility model patent range, It should be included in present utility model application the scope of the patents.
