Description
Technical field
The present invention relates to mast technical field more particularly to mast auto-unlocking devices.
Background technique
Elevation mast is all widely used in various fields, in use, it is sometimes desirable to be kept for a long time
Extended state just needs mechanically to lock each section at this time, to prevent in decompression mast glide.Common mechanical locking
Method have bolt-type and two kinds of hood type, regardless of requiring personnel using any mode and being unlocked manually at the scene.With
The extension of application field, mast require the more to rise the more high, the elemental height of opposite mast is also higher and higher therewith, in no external world
Under the assistance of tool, corresponding height, which is not achieved, in operator cannot achieve unlock, and in addition some fields operator can not arrive at
Scene realizes that unlock is more difficult.
Summary of the invention
Technical problem to be solved by the invention is to provide easy to operate, it is able to achieve without tool and operation of ascending a height
The mast auto-unlocking device of more piece mast automatic unlocking.
The present invention is to be achieved by the following technical programs:
Mast auto-unlocking device comprising bolt retaining mechanism and automatic unlocking mechanism, the bolt retaining mechanism packet
It includes and is fixedly installed in the upper bayonet mount of the every set successively of mast, the bolt being installed in bayonet mount, is set on bolt
Guide ring and locking spring, the latch end stretches out bayonet mount, locking groove is equipped in bayonet mount, locks bullet
Spring and guide ring are respectively positioned in locking groove and locking spring one end is fixedly connected with locking groove, and the other end is fixed with guide ring
Connection, the automatic unlocking mechanism include the U-shaped plate and sliding solution closing piece for being successively fixedly installed in latch end, the U-shaped
Plate upper outside be equipped with U-shaped plate inclined-plane and its U-lag be installed on the U-shaped plate of a section bolt and sliding solve closing piece it
Between, the sliding solution closing piece bottom inside is equipped with the sliding solution closing piece inclined-plane matched with U-shaped plate inclined-plane.
Further, bolt is equipped with positioning spline, is equipped with the locating plate being fixedly connected with bayonet mount in positioning spline.
Further, the front end of bolt is equipped with nylon slide head.
Further, nylon slide head top and body of rod contact site are plane.
Further, it most descends the auto-unlocking device of section to be fixedly installed with automatic driving part, pushes outward or drawing is inserted
Pin.
Further, automatic driving part is cylinder.
Advantageous effect of the invention
The mast auto-unlocking device that the present invention protects, when being in the lock state, due to the effect of locking spring, bolt
Front end is inserted into corresponding section set, when unlock, only needs manually or automatically, such as to use oil cylinder, cylinder, electric pushrod
Or any other mode extracts the bolt of most next section, the upper section mast body of rod glides under the effect of gravity, is mounted in a upper section
Its sliding solution closing piece of the upper auto-unlocking device of section set and the U-shaped plate phase mounted in next another upper tripper of set successively
Contact generates an outside lateral force since two inclined-planes of contact portion cooperate, and makes top equipped with sliding unlock
The bolt sidesway of block, so that bolt is extracted, it is easy to operate, more piece mast is able to achieve certainly without tool and operation of ascending a height
Dynamic unlock.
Detailed description of the invention

Specific embodiment
Mast auto-unlocking device comprising bolt retaining mechanism and automatic unlocking mechanism, the bolt retaining mechanism packet
It includes the bayonet mount 1 being fixedly installed on the every set 9 successively of mast, the bolt 2 being installed in bayonet mount, be set in bolt
On guide ring 3 and locking spring 4, bayonet mount and mast are fixedly connected with mode per bolt preferred between set successively, convenient
Dismounting, the latch end stretch out bayonet mount, locking groove 12 are equipped in bayonet mount, locking spring and guide ring are equal
Positioned at locking groove in and locking spring one end with locking groove be fixedly connected, the other end is fixedly connected with guide ring, it is described oneself
Dynamic unlocking mechanism includes successively being fixedly installed in U-shaped plate 7 and sliding solution closing piece 8, U-shaped plate and the sliding unlock of latch end
It can be bolted and fixed between block and bolt, easy disassembly, the U-shaped plate upper outside is equipped with U-shaped plate inclined-plane
13 and its U-lag be installed between the U-shaped plate of a section bolt and sliding solution closing piece, the sliding solves closing piece bottom inside and sets
There is the sliding solution closing piece inclined-plane 14 matched with U-shaped plate inclined-plane, making the two that can generate a lateral force at the time of contact will insert
Pin is pushed outwardly.
Further, bolt is equipped with positioning spline 10, is equipped with the positioning being fixedly connected with bayonet mount in positioning spline
Piece 6 is set in the scope of activities of bolt within respective range, prevents bolt from crossing movement, and when locking damages mast, or solution
Bolt is thoroughly extracted when lock.
Further, the front end of bolt is equipped with nylon slide head 5, makes it when mast moves up and down, bolt is only in the body of rod
On slide and unlikely scuffing mast surface.
Further, nylon slide head top and body of rod contact site are plane 15, in pressure-bearing Shi Keyu body of rod contact portion
In face contact, to reduce compression.
Further, it most descends the auto-unlocking device of section to be fixedly installed with automatic driving part, pushes outward or drawing is inserted
Pin is realized and automatically controls unlock, more time saving and energy saving, is not necessarily to artificial drawing bolt.
Further, automatic driving part is cylinder 11, and automatic far distance control unlock may be implemented, operate more convenient province
Power.
When mast is in raised configuration, due to the effect of locking spring, the front end of bolt is inserted into a pole body
In the groove of internal gib block, corresponding two section realizes locking, when unlock, only needs manually or automatically, such as using oil cylinder,
Cylinder, electric pushrod or any other mode extract the bolt of most next section, the upper section mast body of rod under the effect of gravity under
It is sliding, its sliding solution closing piece of upper auto-unlocking device is covered successively mounted in upper one fills with mounted in another the upper unlock of next set successively
The U-shaped plate set is in contact, and since two inclined-planes of contact portion cooperate, generates an outside lateral force, makes
Bolt sidesway of the portion equipped with sliding solution closing piece, so that bolt is extracted, it is easy to operate, it can without tool and operation of ascending a height
Realize more piece mast automatic unlocking.
In conclusion the mast auto-unlocking device that the present invention is protected, easy to operate, without tool and work of ascending a height
Industry is able to achieve more piece mast automatic unlocking, and can realize what long-distance automatic control unlock and realization can not be reached in personnel
Position analysis unlock.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
