Description
Technical field
The utility model belongs to clamp art, more particularly, to a kind of self-locking type fixture.
Background technology
In modern Bridge guardrail and highway barrier, according to the grade of highway, consider its safety, harmony,
Need the factors such as the characteristic of protection object and live geometrical condition to determine anti-collision level, then further according to this body structure, economy with
And the factors such as construction and maintenance carry out the selection of structural form, usually concrete guardrail are selected to be located at the two of bridge and highway
Side, primary structure member of the concrete guardrail as bridge and highway barrier have the good characteristic for absorbing vehicle collision energy, together
When also allow for processing.
In concrete guardrail installation, because concrete guardrail volume is big, weight reaches 2.5 tons or so, installation position
Set narrow, line style requirement height after installation.When leading to the installation fee of concrete guardrail, expense is artificial, safety is poor, cannot be satisfied high speed
The requirement of high road pavement construction do mechanization operation.
Existing construction technology, there are two ways to concrete guardrail piece installation in median strip generally uses：
Method one is lifted using the truck crane of 8T.4 meters of concrete guardrail leaf length, 1 meter of height, it is contemplated that concrete protects
Appearance must smooth out and neatly after the installation of column piece, so concrete guardrail piece can not design hole for hoist.The lifting of truck crane is adopted
It being bound and is lifted with steel wire rope, steel wire rope is soft connection, when concrete guardrail piece is seated on sleeper beam, will produce shaking,
In addition concrete guardrail piece volume is big, weight is big, installer can not accurate accurately raising and lowering, swing.Often
When lifting in place, safety accident easily occurs.And the installation time in place is long, installs a piece of concrete guardrail piece and needs 20-30
Minute metal binding wire rope, lifting solve steel wire rope in place, probably need 4-5 worker's hoistman one, lifting commander's work one
Name, installer 2-3 people.
Method two is installed in place using gantry crane.Concrete guardrail piece is first lifted into sleeper beam with loading machine or fork truck
Near, then coordinate bottle gouard moved by hands, additional artificial knocking and push to carry out precise positioning with portal frame.This method is original
Artificial semi-mechanization operation, is installed time 20-30 minutes in place, needs artificial 5-6 people loader engineer one, portal frame movement
Worker 2, installer 3.
Because of concrete guardrail sheet weight weight, volume is big, and the position dimension of fixing bolt is deviated when prefabricated, Er Qiexu
Up and down, the installation positioning around that several centimetres are completed on narrow sleeper beam, realize perfect line style installation.
Existing lifting common apparatus is all soft steel wire rope connection, can not be accurate, easily realizes 360 degree of low-angle adjustment.Institute
Long with the set-up time, installer is more, and safety is poor.

17 inner groovy direction of annular groove is consistent with the telescopic direction of extensible member 3,17 inner groovy direction of annular groove and extensible member 3
Telescopic direction be vertical direction, hydraulic cylinder 11 is used to drive the movement of telescopic rod 12, and the movement of telescopic rod 12 for pair
The movement of first rotation axis 7, support plate 6 is closed when the first rotation axis 7 moves down, and support plate 6 is opened when the first rotation axis 7 moves up
It opens.
When extensible member 3 is in shortest length, the angle between first support arm 4 and second support arm 5 is minimum angles, at this time
The distance between opposite support plate 6 is maximum distance, and fixture 2 is open configuration；When extensible member 3 is in extreme length, first
Angle between arm 4 and second support arm 5 is maximum angle, is bonded at this time with respect to support plate 6, and fixture 2 is clamped condition.
Ball 13 is always positioned in annular groove 17, since there is concrete guardrail larger weight, fork truck in operation can
Generate mobile vibration, to influence the clamping of fixture 2 so that telescopic rod 12 generated under the action of vibration it is certain upper
Lower movement, and telescopic rod 12 is fixedly connected with hydraulic cylinder 11 at this time, to so that ball 13 generates certain vibration so that rolling
Pearl 13 moves freely certain buffering, it can be achieved that vibration under the action of impact force in annular groove 17, and ball 13 exists
Movement in annular groove 17, impact of the less vibration to holder 1 so that holder 1 more has higher service life.
In actual use, holder 1 is fixed on the hoistable platform of fork truck, so that fixture under the action of fork truck
2 are located above the object to be clamped, and fixture 2 is directed at wanted concrete guardrail by the effect of rotary motor 10, will be stretched
Part 3 is shunk so that extensible member 3 is whole up to be pushed up, and ball 13 withstands the bottom of annular groove 17, the telescopic rod 12 of subsequent extensible member 3
It retracts, the first rotation axis 7 in second support arm 5 is above carried, to which fixture 2 opens, the hoistable platform of fork truck is declined, fixture 2
On concrete guardrail, extensible member 3 is stretched out, ball 13 withstands 17 top of annular groove, and telescopic rod 12 extends, and drives second
The first rotation axis 7 on arm 5 declines, and to which fixture 2 clamps, the support plate 6 in second support arm 5 is close to concrete guardrail；It will fork
The hoistable platform of vehicle rises, and fixture 2 is under the action of being clamped object gravity so that and the first rotation axis 7 is forced downwards always,
Concrete guardrail the more is pressed from both sides the more tight, and ball 13 is detached from 17 top of annular groove after object is clamped, and ball 13 is interior certainly in annular groove 17
By moving.
Holder 1 is fixed on the hoistable platform of 7t fork trucks, is lifted to holder 1 by the hoistable platform of fork truck, and move
Fixture 3 is moved on concrete guardrail by electrical forklift, can be in institute by adjusting rotary motor 10 come the steering of alignment jig 3
Self-locking is realized under the action of folder object gravity, and the more locks the more tight, it is ensured that concrete guardrail is when transporting and installing in place
Stability, it is ensured that safety.
Since fixture 3 needs to realize the action turned round with opening and closing, so having installed two-way liquid additional in the hydraulic system of fork truck
Pressure control valve and two operation handles.It can realize the clamping of concrete guardrail piece by truck driver simple operations, rise
It hangs, transports, upper and lower 360 degree installations in place all around and loose folder action.
This method coordinates fork truck lifting transhipment concrete guardrail, can safely and effectively realize large volume, the height of large-tonnage
The Fast Installation of fast highway median strip concrete guardrail, installing a piece of concrete guardrail piece only needs 2-3 minutes, has saved big
The time of amount；This method construction only needs truck driver one, installer one.It can be the Serial regulation of concrete guardrail
Not only beautiful to best position but also quick, time saving, saving of labor, safety is good.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model；Cause
