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 utility model pertains only to the lift structure on basis, it, can be practical new by this when specifically used
There is the cooperation of equipment described in type the equipment of transport function to use.
Utility model works principle is as follows:
The utility model is moved at big quality concrete pipe fitting first, so that big quality concrete pipe fitting is located at two
Between grip block.The utility model is in elongation state now at original state, i.e. the two of dual-rod hydraulic cylinder piece piston rod, this
It carves grip block and not yet contacts big quality concrete pipe fitting, so grip block is located at vertical height lowest part in self 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 clamp 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 meeting of moving up of two grip blocks is so that the big quality concrete pipe fitting while realization that are clamped by it move up work
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 to operate, it is only necessary to be operated with the equipment with the function of motion that the utility model is used cooperatively.It is described
Equipment with the function of motion can be small-sized lifting machine etc..
It should be noted that the utility model uses the power take-off mechanism with a movement to can be realized to big quality
The radial of concrete pipe clamps and vertically to two movements of promotion.Although and hawser in the prior art bundlees artificial mobility
It is relatively strong, but complicated operation, especially when big quality concrete tubing circumference does not have the space of hawser nesting, such as
The big quality concrete pipe fitting of the big quality placed on cement flooring, staff can only be by the way of stretching the meaning by round cable
Rope sling is at big quality concrete pipe fitting both ends, and not only work consuming is time-consuming, but also the labor intensity of staff is very big, also easily wears
Hawser, ground and big quality concrete pipe fitting.Meanwhile on the basis of the utility model states function in realization, use very
Simple structure relies solely on support plate and grip block not using the direction-changing drive mechanisms such as connecting rod, rocker arm of any complexity
Transmission cooperation, maintenance rate is very low, and service life is only limited by its founding materials performance itself.
The utility model may be implemented to carry out clamping promotion to the big quality concrete pipe fitting of big quality, while in order to improve
Big quality concrete pipe fitting is promoted and is stablized, prevents big quality concrete pipe fitting from falling off from grip block, the utility model is also adopted
It is limited with initial and end both ends of the clamping mechanism to big quality concrete pipe fitting: when big quality concrete pipe fitting had been elevated
Cheng Zhong can contact two detent bar bottom ends, since detent bar and column are hinged, so detent bar will not influence big quality concrete
The rising of pipe fitting, but rotation can be contacted and present by big quality concrete pipe fitting, when big quality concrete pipe fitting promotes operation
After in place, start motor, motor moves riffled tube rotation by pulley-sprocket-belt, due to the hand of spiral phase of two threaded rods
Instead, so the rotation meeting of riffled tube is so that two threaded rods are backwards to movement, the end of two threaded rods is due to contacting two detent bars, institute
It will push two detent bars with the movement of threaded rod and rotate up to the bottoms of two detent bars and be in contact and realize close conflict, so
Two detent bars can be realized under the case where big quality concrete pipe fitting falls off from grip block to big quality concrete pipe fitting
Load-bearing, prevent the generation of safety accident.Certainly, two sets of equipment can be arranged on a mounting board to improve to big in the utility model
The clamping effect of quality concrete pipe fitting.The clamping mechanism play as security protection project and measures in emergency circumstances.
More preferably, the utility model also provides more brilliant technical side to guarantee the safety of operation process
Case:
1) in order to guarantee that grip block drove big quality concrete pipe fitting moves up operation without deviation, so the application is using the
One, second liang of set positioning sliding block move up to grip block the limit of glide direction, while first, second liang of set positioning sliding block
The drawing that both direction can be carried out to grip block prevents grip block from rotating around the strut of positioning sliding block；
2) the first notch in support plate and grip block clearance fit, the process that moves up of only grip block does not provide displacement
And space compensation, while limit operation further also is carried out to the movement that moves up of grip block；
3) also for preventing grip block from rotating around the strut of positioning sliding block, the utility model is cooperated by guiding mechanism
Two sets of positioning sliding blocks are limited and are oriented to grip block: contacting the guide rod of guiding mechanism when moving to its top on grip block
When, guide rod can be moved outwardly until that guide rod is contacted and realized with the fitting groove on grip block and match to spring force is overcome
It closes.Due to the arc-shaped semicircular of grip block, so it still can persistently contact guide rod during moving up, so make
The spring moment remain substantially stretched state, and drive guide rod to grip block carry out continue compressing contact, and then realize limit lead
To effect and grip block is improved to the clamping effect of big quality concrete pipe fitting.
Meanwhile for grip block and the assembly of positioning sliding block consider that the grip block bottom in the utility model is equipped with
Installation notch, allow the connecting rod of positioning sliding block and strut probeed into from installation notch and respectively with fitting groove and limiting slot into
Row cooperation, while strut both ends are blocked by limit screw cap, prevent grip block from shaking phenomenon occur.When positioning sliding block with
After the assembly is completed, installation notch can be fixed by plugging block or detachable closure for grip block.
The intrados of grip block uses frosted structure basis, can be improved between grip block and big quality concrete pipe fitting
Frictional force.
The utility model compared with prior art, has the advantages that the utility model is simple in sturcture, ingenious in design, energy
It is enough that effectively big quality concrete pipe fitting is clamped, promotes operation, on the basis of guaranteeing operation safety, increase substantially
Working efficiency.
