Embodiment 1

Specific embodiment according to the present utility model is as Figure 1-Figure 5 that the energy-saving prefabricated component of the utility model is used The open triangle boom hoisting of single base, comprising:

Pedestal 1 is lifted, as shown in Fig. 2, lifting pedestal 1 cuts into triangle using thick steel plate, for carrying hoisting axis 2, Lifting pedestal 1 includes connection side, mounting hole and loss of weight delthyrium, in order to avoid stress concentration, in loss of weight delthyrium and lifting bottom The corner of seat 1 is provided with rounded corner；The connection of pedestal 1 is lifted when including the first connection 11, the second connection side 12 and bottom connect Edge fit 13, first connection while 11 and second connect while 12 be located at triangle lifting pedestal 1 left and right both sides, bottom connect Edge fit 13 is located at the bottom edge of the lifting pedestal 1 of triangle, for contacting energy-saving prefabricated component 4, prevents energy-saving prefabricated component 4 sliding It is de-；First connection in the 11, second connection 12 connect with bottom side 13 length it is identical, make to lift pedestal 1 to be in one equilateral three It is angular, the design of equilateral triangle, it can be ensured that triangle boom hoisting can be pressed in the appearance of energy-saving prefabricated component 4 well Face, simultaneously as three connection side indifferences, can arbitrarily choose a connection side when in use and connect with energy-saving prefabricated component 4 Touching, in this way long-time service three hoisting axis 2 abrasion loss be it is the same, can effectively extend the service life of triangular hanging tool.Peace On the connection side on three vertex that dress hole is located at equilateral triangle.First connection while 11, second connection while 12 and bottom connect The lateral surface of edge fit 13 is provided with non-slip groove 14, in this way in lifting, is pressed in energy-saving prefabricated component 4 by non-slip groove 14 Contact site, can play the role of preferably it is anti-skidding, meanwhile, be both provided with non-slip groove 14 on three connection sides, can hang Three 2 indifferences of hoisting axis use when dress, keep each hoisting axis 2 consistent with connection side abrasion condition, convenient for improving boom hoisting Service life, while reducing using difficulty.

Hoisting axis 2, as shown in figure 3, hoisting axis 2 be assemblied in lifting pedestal 1 connection side mounting hole in, and with lifting bottom Plane where seat 1 is vertical, and for carrying and guiding hoist cable 3, there are three the settings of hoisting axis 2, line shape between three hoisting axis 2 At an equilateral triangle；Hoisting axis 2 includes:

Mounting portion 21, mounting portion 21 is located at one end of hoisting axis 2, cylindrical, with mounting hole assemble, by hoisting axis 2 with Pedestal 1 is lifted to connect.

Work department 23, one end of work department 23 is located at one end of mounting portion 21, cylindrical, for carrying and guiding hoist cable 3；23 diameter of work department is greater than the diameter of mounting portion 21, and positioning shaft shoulder 22 is formed between work department 23 and mounting portion 21.

Transition part 24, transition part 24 is located at the other end of work department 23, for the transition between work department 23 and retaining ring 25； Transition part 24 is in semicircular arc along shaft section, convenient for guidance hoist cable 3 to work department 23, while the abrasion hoist cable 3 of minimum.

Retaining ring 25, retaining ring 25 are located at the other end of hoisting axis 2, and the diameter of retaining ring 25 is greater than the diameter of work department 23, is used for Prevent hoist cable 3 from falling off during the work time.

In the embodiments of the present invention, mounting portion 21, work department 23, transition part 24 and retaining ring 25 are integrally formed knot Structure.

Since in lifting work, the weight of energy-saving prefabricated component 4 is generally large, critical between hoisting axis 2 and mounting hole to match It closes, meanwhile, hoisting axis 2 and lifting 1 junction of pedestal are subjected to soldering, it is ensured that its is solid and reliable.When production batch is larger When, for save the cost, manufacture difficulty is reduced, triangle boom hoisting can be processed using monoblock cast.

As shown in figure 4,3 one end of hoist cable passes through the bottom of energy-saving prefabricated component 4 in lifting use process, it will be energy-saving Prefabricated component 4 surrounds, and turns to rope sling using 3 one end of hoist cable, is set in the ipsilateral hoisting axis 2 on bottom connection side 13, slowly slings Hoist cable 3 makes other two hoisting axis 2 catch on hoist cable 3 close to the position of 1 inside of lifting pedestal, due to stress, the lifting of triangle Bottom connection 13 non-slip groove of side, 14 position of pedestal 1 can be pressed on energy-saving 4 surface of prefabricated component, generate frictional force, avoid saving It can 4 slippage of type prefabricated component.

It is risen as shown in figure 5, the embodiments of the present invention additionally provide the energy-saving open triangle of prefabricated component single base The application method of device for hoisting, includes the following steps:

S1 chooses suitable triangle boom hoisting according to the outer diameter of energy-saving prefabricated component 4, it is ensured that in hoisting process, rises The bottom connection side 13 of device for hoisting can be pressed in the outer surface of energy-saving prefabricated component 4 well；

S2, hoist cable 3 bypass energy-saving prefabricated component 4, and 3 one end of hoist cable is set in hoisting axis ipsilateral on the connection side 13 of bottom On 2；

Bottom is connected the 11, second connection 12 intersection point of side when the correspondence hoisting axis 2 of the other side on 13 and first connect by S3 Work department 23 of the hoisting axis 2 at place close to 1 inside of lifting pedestal is fastened on respectively on hoist cable 3；

In hoisting process, if it find that the inside of two hoisting axis 2 cannot tightly close to hoist cable 3, illustrate that triangle rises Device for hoisting is oversized, not can be carried out safty hoisting, needs replacing the triangle boom hoisting of small size；

S4 slowly rises hoist cable 3, tenses hoist cable 3, it is ensured that hoist cable 3 is located at the work department of the hoisting axis 2 of each cooperation 23；

S5 carries out lifting operation to energy-saving prefabricated component 4；

In hoisting process, the state of triangle boom hoisting is paid close attention to, it is ensured that safety；

S6, lifting are completed, and hoist cable 3 is reduced, and unclamp triangle boom hoisting, and the lifting for carrying out next energy-saving prefabricated component 4 is made Industry.

Embodiment 2

As shown in Figure 6,7, in the present embodiment, the energy-saving prefabricated of different-diameter is directed in order to promote triangle boom hoisting The adaptability of part 4 is symmetrically arranged with 6 hoisting axis, 2,6 hoisting axis of spacing distribution along symmetry axis on the connection side 13 of bottom 2 correspond to two-by-two, and the hoisting axis 2 for connecting 12 point of intersection in the 11, second connection with first cooperates, and form three isosceles triangles, The design of isosceles triangle, it can be ensured that in lifting, the midpoint on bottom connection side 13 is pressed in above energy-saving prefabricated component 4, is kept away Exempt from the offset of triangle boom hoisting, while can ensure three connection side uniform forces of triangle boom hoisting, avoids stress not Damage caused by；The hoisting axis 2 is provided in 25 plane of retaining ring of three hoisting axis 2 in side on bottom connection side 13 to be suitble to The diameter range of the energy-saving prefabricated component 4 of lifting, in practical hoisting process, according to the diameter dimension of energy-saving prefabricated component 4, choosing Suitable hoisting axis 2 is taken, lifting operation is carried out.
