Description
Technical field
The present invention relates to a kind of suspension bracket, particularly relate to a kind of corner hollow concrete block special hoisting bar.
Background technology
In the concrete revetment on seashore or river bank, the most all laying the concrete block surface layer as slope formula shore protection, this concrete block has
Having stability strong, anti-wave effect is good, is easy to the most again make and facilitate the advantages such as installation, therefore widely used by hydraulic engineering design.
And due to will washing away for a long time and corroding by sea water, so corner hollow concrete block typically becomes the most thereon when manufacturing
Type goes out suspension hook.Therefore when lifting, how to design and can lift by crane and the suspension bracket of safety, especially for lifting by crane as shown in Figure 1
Weight reaches 2t even 3t and above ultra-large type corner hollow concrete block is particularly important.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of not only can lifting but also the corner hollow concrete block special hoisting bar of safety.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is: it includes that be articulated with on same hinge axis first hangs
Bar and the second suspension rod, for supporting a bracer of corner hollow concrete block, the first described suspension rod and the second suspension rod are by lower beam and court
The upper boom that the left oblique upper of lower beam tilts is constituted, and described bracer is connected with the bottom of lower beam and towards the left obliquely downward extension of lower beam,
The first described suspension rod and the second suspension rod in the raw time two upper booms be mutually flared out, two lower beams draw in, described first
When suspension rod and the second suspension rod are in lifting state, two lower beams are mutually flared out, two upper booms draw in；Described the first suspension rod or second
It is additionally provided with on the medial wall of the upper boom of suspension rod and is easy to corner hollow concrete block special hoisting bar and puts into corner hollow concrete block center hole or from four
The bayonet lock that angle hollow concrete block center hole takes out, this bayonet lock is made up of the bull stick being arranged in a mutually vertical manner and kelly, and bar rotation is installed
On the medial wall of wherein upper boom, and kelly is when external force rotates bull stick, and both can be placed in can on the medial wall of this root upper boom
Level is placed on the projection at another root upper boom medial wall.
The first described suspension rod and the second suspension rod symmetry are articulated with on hinge axis.
Described hinge axis is between the first suspension rod and the second suspension rod and is positioned at the link position of upper boom and lower beam, described
One suspension rod and the second suspension rod in the raw time two lower beams be collapsed into vertical parallel shape, at the first described suspension rod and the second suspension rod
When the state of lifting, two upper booms are collapsed into vertical parallel shape.
Described bull stick is additionally provided with the safety of being easy to extended to outside upper boom and rotates the operating handle of bull stick.
The both sides of described lower beam are additionally provided with and increase the offset auxiliary of area of lower beam and corner hollow concrete block center hole inwall and support block.
It is respectively symmetrically on the upper boom of the first described suspension rod and the upper boom of the second suspension rod and is provided with the lifting hole(eyelet) being easy to suspension hook lifting.
After using above structure, present invention have the advantage that the corner hollow concrete block special hoisting bar of the present invention utilizes corner hollow
The center hole of concrete block, uses two suspension rods that can simultaneously rotate relative to same hinge axis, and makes to be formed between the upper boom of suspension rod folder
Angle, so when lifting, utilizes the gravity of corner hollow concrete block self, and the lower beam of suspension bracket opens toward both sides the most naturally, now connects
It is connected on the bracer bottom lower beam and the most firmly supports the bottom of whole corner hollow concrete block, the lower beam opened propping up the most tightly
The inwall of corner hollow concrete block center hole so that it is sliding can not be produced and keep stable.In sum, the corner of the present invention is empty
Heart concrete block special hoisting bar can realize weight reaching 2t even 3t and the lifting of above ultra-large type corner hollow concrete block, during lifting
Safety coefficient high, lifting speed is also fast, and whole special hoisting bar compact conformation rationally, design ingenious, it is simple, convenient to make.
After additionally bayonet lock is arranged, the kelly of bayonet lock is set level, then can prevent two lower beams from opening, it is simple to it is empty that corner put into by whole special hoisting bar
In the center hole of heart concrete block, it is easy to again after rigging out whole special hoisting bar in the center hole of corner hollow concrete block simultaneously
Take out.
Being articulated with on hinge axis as improvement, the first described suspension rod and the second suspension rod symmetry, when making lifting, stress more steadily may be used
Lean on.
As improvement, described hinge axis is between the first suspension rod and the second suspension rod and is positioned at the link position of upper boom and lower beam,
The first described suspension rod and the second suspension rod in the raw time two lower beams be collapsed into vertical parallel shape, the first described suspension rod and
When two suspension rods are in lifting state, two upper booms are collapsed into vertical parallel shape, make the first suspension rod and the second suspension rod opposite from hinge axle rotate and open
The amplitude opened keeps maximizing, more conducively the lifting of the corner hollow concrete block that the safety of lifting is different with size.
As improvement, described bull stick is additionally provided with the safety of being easy to extended to outside upper boom and rotates the operating handle of bull stick, handle
Setting can make operator rotate bull stick outside two upper booms, eliminates the potential safety hazard operating bull stick between two upper booms and exist.
As improvement, the both sides of described lower beam are additionally provided with increase lower beam and corner hollow concrete block center hole inwall and offset area
Auxiliary supports block, auxiliary support block increase lower beam during lifting with the clamping area of the inwall of corner hollow concrete block center hole,
Further increase security performance.
It is easy to hanging of suspension hook lifting as being respectively symmetrically on improvement, the upper boom of the first described suspension rod and the upper boom of the second suspension rod to be provided with
Hole, facilitates the suspension hook operation to special hoisting bar in hoisting process.
