The erecting by overhang that uses technique scheme to provide, makes originally to need the operation of 2～4 operable hanging chain blocks of people's ability to become simply, only needs now 1 people just can operate safely, greatly reduces human cost.After the erecting by overhang that use technique scheme provides, anchor pole is only subject to along the active force of anchor pole axial direction, has greatly improved the Security of lifting operation.In addition, due to chain block be subject to force direction single, extended the life cycle of chain block, saved instrument cost.
Brief description of the drawings
The schematic diagram of the erecting by overhang that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the schematic diagram of the first link in Fig. 1;
Fig. 3 is that the A of Fig. 1 is to view.
Embodiment
Referring to Fig. 1-Fig. 3, the embodiment of the present invention provides a kind of erecting by overhang, wherein, comprises the first link and the second link; The first link is for being rotationally connected with anchor pole 1, and the direction of rotatingshaft is along the axial direction of anchor pole 1; The second link is fixed on the first link, for hanging chain block (scheming not shown).
The first link can adopt steel plate bending to be suitable shape, also can adopt steel pipe to piece together, bend or weld formation.The second link can be steel pipe or wire rope etc.
The first link and anchor pole are rotationally connected, and the active force that the first link applies anchor pole is along the axial direction of anchor pole.When lifting, no matter chain block pulling force that the second link is applied along where to, when this pulling force is passed to anchor pole, it is all the axial direction along anchor pole, so in 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, makes originally to need the operation of 2～4 operable hanging chain blocks of people's ability to become simply, only needs now 1 people just can operate safely, greatly reduces human cost.After the erecting by overhang that use technique scheme provides, anchor pole is only subject to along the active force of anchor pole axial direction, has greatly improved the Security of lifting operation.In addition, due to chain block be subject to force direction single, extended the life cycle of chain block, saved instrument cost.
Referring to Fig. 1, further, the first link adopts following preferably implementation.The first link comprises that the first round steel 2, the second round steel 3 and the 3rd round steel 4, the second round steel 3 are U-shaped, and the first round steel 2 and the 3rd round steel 4 are separately positioned on the two ends of the second round steel 3; On the second round steel 3, offer the perforate 31 of vertical setting, for being rotationally connected with anchor pole 1; On the first round steel 2 and the 3rd round steel 4, correspondence offers the first through hole 21 and the second through hole 41, the second links wear by the first through hole 21 and the second through hole 41.
In erecting by overhang, the intensity of all parts can be a little more than anchor rod strength, herein, taking the diameter of the first round steel, the second round steel and the 3rd round steel all as 20mm is as example.The size and shape of the perforate of the second round steel and anchor pole joint is according to the size decision of anchor pole, and the setting position basis of perforate is by Heave Here determining positions.Herein, the first link and anchor pole are rotationally connected, and have eliminated stress and have concentrated the destruction of bringing to device.The second round steel be U-shaped can also be by the stressed component that is divided into equably two equivalent of anchor pole 1, concentration phenomenon eliminates stress.
The whole size of the first link and the second link can specifically be set according to the tonnage of the weight in the tonnage of chain block and lifting.Be understandable that, when above-mentioned erecting by overhang level is installed, can be used for tractive weight.
On chain block with crotch.In technique scheme, the first round steel and the 3rd round steel are used for supporting the second link, and the second link is used for hanging chain block.The first link adopts above-mentioned implementation, and required main material and join material and be mine common used material is sought material easy, and single cost is below 20 yuan.
The erecting by overhang that technique scheme provides, adopts round steel to be welded, and sound construction is not easy to damage, and durable in use, cost drops into low, and reusable.In addition, the reliability of erecting by overhang is strong, easy to use, is easy to the on-the-spot operation of grasping.The erecting by overhang that uses technique scheme to provide, can eliminate the tackles causing because of discontinuity and come off, damage, the lifting such as Heave Here fracture defect.
Further, the first round steel 2 and the 3rd round steel 4 all weld with the 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, the second link can be straight-bar 5, straight-bar 5 one end are provided with baffle plate 51, the other end is provided with screw thread, and on screw thread, for mounting nuts, baffle plate 51 and nut are for limiting the position of the second link with respect to the first through hole 21 and the second through hole 41.The other end of straight-bar is set to screw thread, is that after completing, the nut of screwing on screw thread, to prevent that straight-bar 5 from having excessive displacement for the ease of straight-bar 5 is passed to the first through hole 21 and the second through hole 41.
Straight-bar is longer than service life of steel wire rope, and can be by Reusability.Adopt the second link of above-mentioned implementation, simple in structure, manufacturing cost is low.
The erecting by overhang that technique scheme provides, easy and simple to handle, when use, only anchor pole need be connected with the first link bolt, then chain block being suspended on to the second link can lift by crane.Because bolt between the first link and anchor pole is connected, the active force that anchor pole is subject to all can be along the axial direction of anchor pole, thereby greatly reduces the possibility that anchor pole comes off, and has also solved the problem that the operation cycle is long, difficulty of construction is large of lifting by crane in prior art.In addition, the safety coefficient of the hoist having hung is increased, the risk that anchor pole is cut off reduces greatly, the lifting Security of chain block is strengthened, extended chain block life cycle, reduced construction cost, reduced labor intensity and human cost.
Finally it should be noted that: above each embodiment, only in order to technological scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or some or all of technical characteristics is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technological scheme.
