Description

A kind of fast erecting hanger and its application method
Technical field
The present invention relates to the lifting fields of electromechanical installation.More particularly to a kind of fast erecting hanger and its user Method.
Background technique
In the realm of building construction, the lifting operation of material, equipment can be usually encountered.The prior art is more according to construction site Condition setting lifting mast, lifting portal frame or hang hoisting rig using superstructure crossbeam etc., carry out lightweight material, set The standby lifting operation waited.
But not can be used as the crossbeam of suspension centre at the scene, column is also not easy to the case where lifting using hoisting machinery Under, and there is the case where high and low fall on ground, it has not been convenient to set up hanger.
Therefore, the unevenness or pit-hole position on place how are avoided under lesser space environment, it is quick, easy and steady Surely the hanger for lifting operation is set up, is this field technical problem urgently to be resolved.
Summary of the invention
The purpose of the present invention is to provide a kind of fast erecting hanger and its application methods, can be in lesser space environment Under, the unevenness or pit-hole position on place are avoided, quick, easy and steadily erection is used for the hanger of lifting operation.
In order to solve the above technical problems, the invention provides the following technical scheme:
A kind of fast erecting hanger, including support, three supporting legs, three limit card slots, three bolts and lifting lug, it is described The upper end of three supporting legs is hingedly connected on support, and the corresponding limiting card is arranged in the position that the support corresponds to every supporting leg Slot after bolt insertion limit card slot, can limit corresponding supporting leg and be flared out, the limit card slot in circular arc type and with The hinged place of corresponding supporting leg and support is the center of circle, and the lifting lug is set to the bottom of the support, the supporting leg include upper leg with Lower leg, the upper leg and the lower leg are articulated and connected.
Preferably, in above-mentioned fast erecting hanger, the lifting lug is located at the inside in the surrounded space of three supporting legs.
Preferably, in above-mentioned fast erecting hanger, the support includes " fourth " font gusset, " fourth " font Gusset includes two piece of first vertical plate connected vertically and the second vertical plate, and the lifting lug is set to the bottom of the first vertical plate, Wherein two supporting legs and its corresponding limit card slot are set in the first vertical plate and are located at the two sides of the second vertical plate, and in addition one Supporting leg and its corresponding limit card slot are set in the second vertical plate.
Preferably, in above-mentioned fast erecting hanger, the top of first vertical plate and the second vertical plate passes through one Top plate connection.
Preferably, in above-mentioned fast erecting hanger, the lower end of the lower leg is equipped with spring roller, and the two of the lower leg Side is symmetrically arranged with contact footing, when lifting lug does not bear lifting load, the spring roller and ground face contact;When lifting lug receiving is hung When filling load, the spring roller compression, and by contact footing and ground face contact.
Preferably, in above-mentioned fast erecting hanger, the contact footing includes diagonal brace and bottom plate, the diagonal brace Upper end is fixedly connected with lower leg, and the lower end of the diagonal brace is fixedly connected with bottom plate.
The invention also discloses a kind of application methods of fast erecting hanger as described above, include the following steps:
Step 1 adjusts each supporting leg by adjusting the position of bolt in each limit card slot according to live site condition Opening angle, have the case where high and low fall to adapt to ground, when ground is higher, tune up the opening angle of corresponding supporting leg;When When ground is lower, the opening angle of corresponding supporting leg is turned down, and the lower leg of each supporting leg is in a vertical state always;
Step 2 hangs chain block on lifting lug or hangs lockset progress lifting operation.
Preferably, in the application method of above-mentioned fast erecting hanger, the lower end of the lower leg is equipped with spring roller, institute The two sides for stating lower leg are symmetrically arranged with contact footing, when hanger needs mobile, by lifting lug zero load, so that the spring roller and ground Face contact facilitates hanger to move integrally;When lifting lug bears lifting load, the spring roller, which is pressurized, to be compressed, so that contact bottom Foot and ground face contact, increase the frictional force between ground and hanger, consolidate hanger.
By techniques disclosed above scheme it is found that compared with prior art, beneficial effects of the present invention are as follows:
Fast erecting hanger provided by the invention, using support, three supporting legs, three limit card slots, three bolts and Lifting lug, the lifting lug are set to the bottom of the support, and the supporting leg includes upper leg and lower leg, and the upper leg and the lower leg are cut with scissors It connects in succession, so that lower leg is in a vertical state always, the lifting load of hanger is transferred on ground, ensure that hanger is whole Body stability;And by the way that the upper end of three supporting legs to be hingedly connected on support, the support corresponds to every supporting leg The corresponding limit card slot is arranged in position can limit corresponding supporting leg and be flared out after the bolt is inserted into limit card slot, The limit card slot is in circular arc type and the center of circle is in the hinged place to correspond to supporting leg and support, therefore, can be according to live place item Part quickly adjusts the opening angle of each supporting leg by adjusting the position of bolt in each limit card slot, has height to adapt to ground The case where low head, tunes up the opening angle of corresponding supporting leg when ground is higher;When ground is lower, corresponding supporting leg is turned down Opening angle so that three leg stabilizing brackets of hanger be set to differentiated levels ground on can stabilizing bracket be set to height On the ground of low injustice, the applicability and stability of hanger are improved, and it is convenient, fast to have the advantages that hanger is set up.
The application method of fast erecting hanger provided in this embodiment, by adjust the position of bolt in each limit card slot come The opening angle for adjusting each supporting leg tunes up the opening angle of corresponding supporting leg when ground is higher;When ground is lower, turn down The opening angle of corresponding supporting leg, thus, it, can be secured according to levelling of the land degree, the ground at scene when setting up the hanger The position in cavity is reserved on situation and ground, is adjusted to the opening angle of three supporting legs, applicability with higher and flexibly Property.Also, the upper leg and the lower leg are articulated and connected, so that lower leg is in a vertical state always, by the lifting load of hanger It is transferred on ground, ensure that hanger overall stability and safety.
