The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
Shown in figure, crane supporting device is comprised of two pairs of bracing frames 2, crane slide bar 3, coaster 10, chain block 4 and spider assemblies 6 before and after the lifting.
When boiler holder 1 is installed, first entablatrance behind the boiler holder 7 is installed, guarantee the stability of boiler holder, the front entablatrance of entablatrance 8 and boiler holder 9 temporary transient elder generations do not install in the boiler holder at this moment, but they and the two pairs of bracing frames 2 in front and back and crane slide bar 3 are fitted together, be assemblied on the boiler holder 1.Coaster 10 is equipped with in crane slide bar 3 inside, and coaster 10 is connected with chain block 4, is used for lifting heat exchanger 5.By the movement of coaster 10, heat exchanger 5 can be transported to the installation site of appointment on the boiler holder 1.
After heat exchanger 5 is in place, crane supporting device is taken off, entablatrance 9 before entablatrance in the boiler holder 8 and the boiler holder is installed on the boiler holder 1, entablatrance 9 is detouchables before middle entablatrance 8 and the boiler holder.As shown in Figure 5; prefabrication and assembly construction hole on the front entablatrance 9 of entablatrance 8 and boiler holder in the boiler holder; the central lines of Kong Weiyu heat exchanger 5 required installation sites; guarantee that heat exchanger do not run into other poles on the boiler holder 1 when crane slide bar 3 moves, to avoid potential safety hazard and to damage heat exchanger.Positioning baffle 18 being installed on the boiler holder 1, putting down when heat exchanger 5 touches positioning baffle 18, namely is its correct installation site.
Two pairs of bracing frames (2) are designed to one high and one low structure before and after the lifting, adopt the structure that front support stand is high, bracket of rear mounting is low during mounting heat exchanger 5, this moment is when heat exchanger 5 is hung the height of demand, only need enforce a little heat exchanger 5, overcome the static friction force of coaster 10, make coaster 10 mobile backward along crane slide bar 3 with heat exchanger 5, by the deadweight of heat exchanger 5, easily its carrying is put in place.During dismounting, low bracing frame is front, and high carriage is rear, and heat exchanger 5 by its deadweight, can be dismantled along being axially slided to outside the boiler holder of crane slide bar 3 equally very easily like this.
When lifting the boiler of other models, as shown in Figure 6, use the front entablatrance 11 of this model boiler, and the middle entablatrance of this model, same prefabrication and assembly construction hole on these crossbeams, bracing frame 2 and slide bar 3 are constant, can implement lifting.Realized the demand of same set of suspender installation different product.
Spider assembly 6 is installed in boiler holder 1 bottom, and described tripod assembly 6 comprises tripod 15, vertical extension rod 13 and horizontal expansion bar 14 and device for fastening, plays fixedly boiler holder when the lifting heat exchanger.Described tripod assembly has vertical extension rod 13 and horizontal expansion bar 14.By changing or regulate vertical extension rod 13 and replacing or regulating the bearing force that horizontal expansion bar 14 can increase the spider assembly, adjusting bottom 12 plays the fine setting effect, makes boiler holder 1 integral body can keep balance when stressed.After using end, the horizontal expansion bar can be retracted in the spider 15, be easy to carry.Simultaneously vertical extension rod 13 can be designed to along artis rotatable, and is retracted in the horizontal expansion bar 14.
Described device for fastening comprises circular side shield 16 and claw 17, and eccentric through-hole of processing is installed in it on spider by screw on the circular side shield 16.As shown in Figure 8 circular side shield 16 rotations are got out of the way, spider assembly 6 is installed on the boiler holder 1, then circular side shield 16 as shown in Figure 9, plays spacing effect with spider 15 and claw 17 by the deadweight reposition.
It should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
