Spring, both ends of the spring are connect with top plate and U-shaped frame respectively.
Preferably, the intrados of two grip block is in frosted structure.
It should be noted that the present invention pertains only to the lift structure on basis, it, can will be of the present invention when specifically used
Equipment of the equipment cooperation with transport function uses.
Working principle of the invention is as follows：
The present invention is moved at big quality concrete pipe fitting first so that big quality concrete pipe fitting be located at two grip blocks it
Between.The present invention is in elongation state now at original state, i.e. the two of dual-rod hydraulic cylinder piece piston rod, and grip block is not yet this moment
Big quality concrete pipe fitting is contacted, so grip block is located at vertical height lowest point in its own gravity state.
Then dual-rod hydraulic cylinder controls two piston rod retractions, and drives two support plates and two grip block out movements, when
Two grip blocks are clamped it after contacting big quality concrete pipe fitting, but two support plates are still in out movement this moment, in addition
Grip block is to be slidably matched with positioning sliding block, so two grip blocks can be in the opposite effect of support plate and big quality concrete pipe fitting
Under moved up, i.e., grip block can relative positioning sliding block moved up, and grip block can move into corresponding branch in this process
In first notch of fagging.The moving up of two grip blocks can so that realization moves up work simultaneously by the big quality concrete pipe fitting of its clamping
Industry, until grip block is moved to positioning sliding block and contacts plugging block at its installation notch.In this way, realizing big quality concrete pipe
Part, when needing operating, it is only necessary to which the equipment with the function of motion being used cooperatively with the present invention is operated.It is described to have
The equipment of the function of motion can be small-sized lifting machine etc..
It should be noted that the present invention is using tool, there are one the power take-off mechanisms acted can be realized to big quality coagulation
The radial of native pipe fitting is clamped and vertically to two actions of promotion.Although and the artificial mobility of hawser in the prior art binding compared with
By force, but operation is complex, especially when big quality concrete tubing circumference does not have the space of hawser nesting, such as water
The big quality concrete pipe fitting of big quality placed on muddy ground face, staff can only be by the way of stretching the meaning by round hawser
Big quality concrete pipe fitting both ends are sleeved on, not only work consuming takes, but also the labor intensity of staff is very big, also easily wears cable
Rope, ground and big quality concrete pipe fitting.Meanwhile on the basis of the present invention states function in realization, use very simple
Structure does not use direction-changing drive mechanisms, the transmissions for relying solely on support plate and grip block such as connecting rod, the rocking arm of any complexity to match
It closes, maintenance rate is very low, and service life is only limited by its founding materials performance itself.
The present invention may be implemented to carry out clamping promotion to the big quality concrete pipe fitting of big quality, while in order to improve to big
Quality concrete pipe fitting, which is promoted, to be stablized, and prevents big quality concrete pipe fitting from falling off from grip block, the present invention also uses screens machine
Structure limits the initial and end both ends of big quality concrete pipe fitting：When big quality concrete pipe fitting is during being elevated, meeting
Two screens bar bottom ends are contacted, since screens bar and column are hinged, so screens bar does not interfere with the upper of big quality concrete pipe fitting
It rises, but can contact and present rotation by big quality concrete pipe fitting, after big quality concrete pipe fitting promotes operation in place, open
Dynamic motor, motor move riffled tube by pulley-sprocket-belt and rotate, since the hand of spiral of two threaded rods is on the contrary, within institute
The rotation of screwed pipe can make two threaded rods backwards to movement, and the end of two threaded rods is due to contacting two screens bars, so threaded rod
The mobile bottom that two screens bars can be pushed to rotate up to two screens bars be in contact and realize close conflict, such two screens bar
The load-bearing to big quality concrete pipe fitting can be realized under the case where big quality concrete pipe fitting falls off from grip block, prevented
The only generation of safety accident.Certainly, two complete equipments can be arranged to improve to big quality concrete pipe in the present invention on a mounting board
The clamping effect of part.The clamping mechanism play as security protection project and measures in emergency circumstances.
More preferably, the present invention also provides more remarkable technical solution to ensure the safety of operation process：
1）In order to ensure that grip block drove big quality concrete pipe fitting moves up operation without deviation, thus the application using first,
Second liang of set positioning sliding block to grip block move up the limit of glide direction, while first, second liang of set positioning sliding block can
To carry out the drawing of both direction to grip block, prevent grip block from being rotated around the strut of positioning sliding block；
2）The first notch in support plate and grip block clearance fit, not the process that moves up of only grip block provide displacement and sky
Between compensate, while limit operation further also is carried out to the action that moves up of grip block；
3）Also for preventing grip block from being rotated around the strut of positioning sliding block, the present invention coordinates two sets of positioning by guiding mechanism
Sliding block is limited and is oriented to grip block：When moved on grip block its top contact the guide rod of guiding mechanism when, guide rod
It can be moved outwardly until that guide rod contacts with the fitting groove on grip block and realizes cooperation to overcoming spring force.Due to clamping
The arc-shaped semicircular of block, so it is during moving up or can persistently be contacted to guide rod, so that the spring moment
Remain substantially stretched state, and drive guide rod to grip block carry out continue compressing contact, and then realize limition orientation effect and
Improve clamping effect of the grip block to big quality concrete pipe fitting.
Meanwhile for grip block and positioning sliding block assembly consider, the present invention in grip block bottom be equipped with installation
Notch so that the connecting rod and strut of positioning sliding block can probe into from installation notch and be matched respectively with fitting groove and limiting slot
It closes, while strut both ends is blocked by limit screw cap, prevent grip block from shaking phenomenon occur.When positioning sliding block and clamping
It is packaged match after the completion of, installation notch can be fixed by plugging block or detachable closure.
The intrados of grip block uses frosted architecture basics, can improve between grip block and big quality concrete pipe fitting
Frictional force.
Compared with prior art, the present invention having the following advantages that：The configuration of the present invention is simple, it is ingenious in design, it can be effectively
Big quality concrete pipe fitting is clamped, promotes operation, on the basis of ensureing job safety, increases substantially work effect
Rate.
