Aforesaid erecting by overhang, preferably,

Said first link comprises first round steel, second round steel and the 3rd round steel, and said second round steel is the U type, and said first round steel and said the 3rd round steel are separately positioned on the two ends of said second round steel;

Offer the perforate of vertical setting on said second round steel, be used for being rotationally connected with said anchor pole;

Correspondence offers first through hole and second through hole on said first round steel and the 3rd round steel, and said second link wears through said first through hole and said second through hole.

Aforesaid erecting by overhang, preferably,

Said first round steel and said the 3rd round steel all weld with said second round steel.

Aforesaid erecting by overhang, preferably,

Said second link is a straight-bar; Said straight-bar one end is provided with baffle plate; The other end is provided with screw thread, is used to install nut on the said screw thread, and said baffle plate and said nut are used to limit the position of said second link with respect to said first through hole and said second through hole.

The erecting by overhang that uses technique scheme to provide, the operation of hanging chain block that makes script need 2～4 people to operate becomes simply, only needs 1 people just can operate safely now, greatly reduces human cost.Behind the erecting by overhang that the use technique scheme provides, anchor pole only receives along the active force of anchor pole axial direction, has improved the Security of lifting operation greatly.In addition and since chain block receive force direction single, prolonged the life cycle of chain block, practiced thrift the instrument cost.

Description of drawings

The schematic representation of the erecting by overhang that Fig. 1 provides for the utility model embodiment;

Fig. 2 is the schematic representation of first link among Fig. 1;

Fig. 3 is that the A of Fig. 1 is to view.

Embodiment

Referring to Fig. 1-Fig. 3, the utility model embodiment provides a kind of erecting by overhang, wherein, comprises first link and second link; First link is used for being rotationally connected with anchor pole 1, and the direction of rotatingshaft is along the axial direction of anchor pole 1; Second link is fixed on first link, is used to hang chain block (scheming not shown).

First link can adopt the steel plate bending to be suitable shape, also can adopt steel pipe to piece together, bend or weld formation.Second link can be steel pipe or wire rope etc.

First link and anchor pole are rotationally connected, and the active force that first link applies anchor pole is along the axial direction of anchor pole.During lifting, no matter the pulling force that chain block applies second link along where to, when this pulling force is passed to anchor pole; It all is axial direction along anchor pole; So in the lifting process, the stability of anchor pole can be guaranteed, the Security of lifting operation is improved.

The erecting by overhang that uses technique scheme to provide, the operation of hanging chain block that makes script need 2～4 people to operate becomes simply, only needs 1 people just can operate safely now, greatly reduces human cost.Behind the erecting by overhang that the use technique scheme provides, anchor pole only receives along the active force of anchor pole axial direction, has improved the Security of lifting operation greatly.In addition and since chain block receive force direction single, prolonged the life cycle of chain block, practiced thrift the instrument cost.

Referring to Fig. 1, further, preferred implementation below first link adopts.First link comprises that first round steel 2, second round steel 3 and the 3rd round steel 4, the second round steel 3 are the U type, and first round steel 2 and the 3rd round steel 4 are separately positioned on the two ends of second round steel 3; Offer the perforate 31 of vertical setting on second round steel 3, be used for being rotationally connected with anchor pole 1; Correspondence offers first through hole 21 and second through hole, 41, the second links wear through first through hole 21 and second through hole 41 on first round steel 2 and the 3rd round steel 4.

The intensity of each parts can be a little more than anchor rod strength in the erecting by overhang, here, all is that 20mm is an example with the diameter of first round steel, second round steel and the 3rd round steel.The size of the perforate of second round steel and anchor pole joint and shape be according to the decision of the size of anchor pole, perforate the position is set according to by the Heave Here determining positions.Here, first link and anchor pole are rotationally connected, and have eliminated stress and have concentrated the destruction of bringing to device.Second round steel is the U type can also be with the stressed component that is divided into two equivalent equably of anchor pole 1, and concentration phenomenon eliminates stress.

The whole dimension of first link and second link can specifically be set according to the tonnage of chain block and the tonnage of the weight in the lifting.It is understandable that, when above-mentioned erecting by overhang level is installed, promptly can be used for the tractive weight.

Have crotch on the chain block.In the technique scheme, first round steel and the 3rd round steel are used to support second link, and second link is used to hang chain block.First link adopts above-mentioned implementation, required main material and join material and be the mine common used material, and it is easy to seek material, and single cost is below 20 yuan.

The erecting by overhang that technique scheme provides adopts round steel weldering system, and sound construction is not easy to damage, and durable in use, cost drops into low, and reusable.In addition, the good reliability of erecting by overhang, easy to use, be easy to the on-the-spot operation of grasping.The erecting by overhang that uses technique scheme to provide can be eliminated the tackles that causes because of discontinuity and come off, damages, lifting such as Heave Here fracture defective.

Further, first round steel 2 and the 3rd round steel 4 all weld with second round steel 3, so that the stability of whole erecting by overhang is better, more durable.

Referring to Fig. 1, in the present embodiment, second link can be straight-bar 5; Straight-bar 5 one ends are provided with baffle plate 51; The other end is provided with screw thread, is used to install nut on the screw thread, and baffle plate 51 is used to limit the position of second link with respect to first through hole 21 and second through hole 41 with nut.The other end of straight-bar is set to screw thread, is for the ease of straight-bar 5 being passed first through hole 21 and second through hole 41, and after the completion, the nut of screwing on the screw thread has excessive displacement to prevent straight-bar 5.

Straight-bar is than wire rope long service life, and ability is used repeatedly.Adopt second link of above-mentioned implementation, simple in structure, the manufacturing cost is low.

The erecting by overhang that technique scheme provides, easy and simple to handle, only need during use anchor pole is connected with the first link bolt, then chain block being suspended on second link can lift by crane.Because bolt is connected between first link and the anchor pole, the active force that anchor pole receives all can be along the axial direction of anchor pole, thereby greatly reduces the possibility that anchor pole comes off, and has also solved and has lifted by crane the problem that the operation cycle is long, difficulty of construction is big in the existing technology.In addition; The safety coefficient of the cucurbit lifting that suspension is good is increased; The risk that anchor pole is cut off reduces greatly, the lifting Security of chain block is able to strengthen, prolonged chain block life cycle, reduced construction cost, reduced labor intensity and human cost.

What should explain at last is: above each embodiment is only in order to the technological scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of each embodiment's technological scheme of essence disengaging the utility model of relevant art scheme.
