Summary of the invention:
This utility model provides a kind of device carrying out bolt fastening in having the deep narrow space of obstacle, and this device utilizes bicycle
Principle is converted to open space pulls rocking bar up and down by pulling rocking bar about deep narrow space, reaches to solve conventional means and cannot be carried out
There is the problem that the deep narrow space pipeline bolt of obstacle fastens.
This utility model solves its technical problem and be the technical scheme is that
A kind of have the deep narrow space of obstacle in carry out the device of bolt fastening, including stainless steel strut, driving gear, driven tooth
Wheel, ratchet, ratchet, spring leaf, rocking bar, chain, detachable jaw, it is characterised in that: the fixing active respectively of stainless steel strut two ends
Gear and driven gear, chain is enclosed within driving gear and driven gear, and ratchet one end and spring leaf one end are separately fixed at master
On moving gear, the ratchet other end and the spring leaf other end are separately fixed on ratchet, and ratchet and rocking bar are fixed together, and ratchet
Being co-axially mounted with driving gear, detachable jaw adsorbs on driven gear
This utility model also includes protective cover, and protective cover covers on outside chain, covers chain, prevents accident.
Described stainless steel strut is adopted as 5mm thickness Q235 steel plate and is made, and is ensureing fixing driving gear and driven gear
Under premise, reduce steel plate area to alleviate weight.
Described chain is made up of 8-shaped inner guide plate, the outer guide plate of 8-shaped and pin, outer guide plate parcel inner guide plate, and passes through
Pin is fixed.
Described ratchet is connected with driving gear by bearing.
Described rocking bar is steel handle, and ratchet is the gear of lance tooth mouth.
Described ratchet and spring leaf are fixed on driving gear, and spring leaf recovers naturalness under elastic force effect and passes through spine
Pawl locking teeth mouth, when ratchet rotates clockwise, ratchet lance tooth mouth is by ratchet jack-up, one tooth mouth position of pawl wheel, spine
Pawl locks next tooth mouth under spring leaf effect.Described ratchet is the hook members of locking ratchet lance tooth mouth, spring leaf
For rustless steel band steel band.
Described protective cover is that 2mm thickness stainless-steel sheet is made, and chain gamut is wrapped up by protective cover.
Described detachable jaw is circular steel components, and inside groove is more bigger than bolt, and back is convex block, by draw-in groove and magnetic
Power is adsorbed on driven gear.
The beneficial effects of the utility model are: by the device of this pipeline bolt fastening, shake pulling about deep narrow space
Bar is converted to open space and pulls rocking bar up and down, it is possible to resolve particularly there is an obstacle in deep narrow space at pipeline, and with conventional hands
The problem carrying out bolt fastening in the environment of Duan Wufa operation.Simple to operate, cost is relatively low.
Accompanying drawing illustrates:
Fig. 1 is this utility model device generalized section.
Reference: 1-stainless steel strut, 2-driving gear；3-driven gear, 4-ratchet, 5-ratchet, 6-spring leaf, 7-shakes
Bar, 8-chain, 9-protective cover, the detachable jaw of 10-.
Detailed description of the invention:
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Shown in Fig. 1, this utility model includes stainless steel strut 1, driving gear 2, driven gear 3, ratchet 4, ratchet 5, bullet
Reed 6, rocking bar 7, chain 8, protective cover 9, detachable jaw 10, it is characterised in that: driving tooth is fixed at stainless steel strut 1 two ends respectively
Wheel 2 and driven gear 3, chain 8 is enclosed within driving gear 2 and driven gear 3, and ratchet 5 one end and spring leaf 6 one end are fixed respectively
On driving gear 2, ratchet 5 other end and spring leaf 6 other end are separately fixed on ratchet 4, and ratchet 4 and rocking bar 7 are fixed on
Together, and ratchet 4 is co-axially mounted with driving gear 2, and ratchet 4 is connected with driving gear 2 by bearing, described detachable jaw 10
For circular steel components, inside groove is more bigger than bolt, and back is convex block, detachable jaw 10 by draw-in groove and magnetic-adsorption from
On moving gear 3, protective cover 9 covers on outside chain 8, covers chain 8, prevents accident；Described chain 8 is led by 8-shaped
The outer guide plate of plate, 8-shaped and pin composition, outer guide plate parcel inner guide plate, and fixed by pin.
