Description
Technical field
The invention belongs to constructing tunnel technical field of auxiliary equipment, and in particular to a kind of section of jurisdiction grabbing device.
Background technology
, it is necessary to be grabbed using the section of jurisdiction of segment crane during shield formula tunneling boring hard rock mole tunnel excavation is used
Take device to capture section of jurisdiction, then transport to destination, then section of jurisdiction is put down.When there is the crawl of left and right two section of jurisdiction
Kong Shi, it is necessary to captured with the section of jurisdiction grabbing device of double extraction heads.The section of jurisdiction grabbing device for double extraction heads that tradition uses
In, extract head at using be rotatably inserted into or vertical displacement insertion section of jurisdiction crawl hole in the form of complete insertion section of jurisdiction, insertion section of jurisdiction
Afterwards, so complete section of jurisdiction crawl.But section of jurisdiction is reinforced concrete structure, in manufacturing process, often there are two sections of jurisdiction
The excessive situation of hole site error.Therefore, the form of traditional two kinds extraction head grasping pipe pieces often can not meet use, scene
During operation, worker need to by section of jurisdiction hole carry out perforate or polishing again, when serious, section of jurisdiction need re-work, can just be crawled and
Handling, labor intensity is big, and operating efficiency is low.
The content of the invention
The present invention is to solve when section of jurisdiction hole site error is excessive, traditional grabbing device can not normal use, need
Section of jurisdiction hole progress again perforate or polishing setting are re-worked, workload increase, labor intensity increase, operating efficiency is low etc.
Technical problem, so as to provide a kind of section of jurisdiction grabbing device that normal work is remained in the case where section of jurisdiction hole error is excessive.
In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：
A kind of section of jurisdiction grabbing device, including hanging beam, suspender and rotating shaft, rotating shaft link together hanging beam and suspender；It is described
Suspender includes fixed cover component and telescopic component, and the fixed cover component includes fixed cover and fixed cover poppet, fixed cover carry
Lifting head is arranged on one end of fixed cover, and shaft hole is provided with fixed cover, voussoir hole, voussoir hole are provided with the left of fixed cover
It is vertical with shaft hole；Rotating shaft links together hanging beam and fixed cover through the shaft hole on the hole and fixed cover on hanging beam；Institute
Stating telescopic component includes telescopic and telescopic poppet, and telescopic poppet is arranged on one end of telescopic, telescopic it is another
One end is slidably mounted in fixed cover and is in contact with the inclined-plane of voussoir, and voussoir is arranged in the voussoir hole of fixed cover.
One end that telescopic is arranged in fixed cover is provided with the inclined-plane line of arc connector, arc connector and voussoir
Contact.On the one hand linear contact lay can make voussoir that telescopic is limited in fixed cover, on the other hand can prevent voussoir from sliding.
The inclined-plane of the voussoir and the angle of vertical direction are θ, and θ is less than the angle of friction of voussoir and arc connector.Adopt
Together with ensuring that voussoir can stably limit telescopic with fixed cover with this structure.
One end of the voussoir is provided with adjustment hole, and fixture block is provided with adjustment hole.Fixture block plays second protection to voussoir
Effect, be again prevented from voussoir and come off.
The fixed cover is located at the length that the length on the left of shaft hole is located at less than fixed cover on the right side of shaft hole.
The leading inside of the fixed cover poppet and telescopic poppet is arcwall face.Arcwall face structure to be lifted
In head quick insertion section of jurisdiction hole.
The present invention is slidably mounted in fixed cover by telescopic, and limits the position in telescopic by voussoir, to
The distance between fixed cover poppet and telescopic poppet are adjusted, to adapt to the section of jurisdiction hole of different pitch-rows, improves applicability, i.e.,
Make be section of jurisdiction pitch-row mismachining tolerance it is excessive in the case of, need to only adjust the i.e. achievable section of jurisdiction in position of the voussoir in voussoir hole just
Often crawl, simplify workload, improve operating efficiency.And simple in construction, low manufacture cost of the invention.
Brief description of the drawings
Fig. 1 is a kind of structural representation of section of jurisdiction grabbing device of the present invention.
Fig. 2 is Fig. 1 A-A to sectional view.
Fig. 3 is use state figure figure one of the present invention.
Fig. 4 is use state figure figure two of the present invention.
Embodiment
As Figure 1-4, a kind of section of jurisdiction grabbing device, including hanging beam 1, suspender and rotating shaft 6, rotating shaft 6 is by hanging beam 1 and suspender
Link together.The suspender includes fixed cover component and telescopic component, and the fixed cover component includes fixed cover 2 and fixed cover
Poppet 3, the leading inside of the fixed cover poppet 3 is arcwall face, and arcwall face structure causes fixed cover poppet quickly to insert
Enter in the hole of section of jurisdiction.Fixed cover poppet 3 is arranged on one end of fixed cover 2, and shaft hole 4, the fixation are provided with fixed cover 2
Length of the set 2 positioned at the left side of shaft hole 4 is less than the length that fixed cover 2 is located at the right side of shaft hole 4.It is provided with the left side of fixed cover 2
