The specific embodiment
For above-mentioned and other purpose of the present utility model, feature and advantage can be become apparent, preferred embodiment of the present utility model cited below particularly, and shown in the conjunction with figs., be described in detail below:
Please refer to shown in Figure 2ly, the insulation structure for the lifting facility of the utility model first embodiment comprises a supporter 1, a pulley 2, an inverted impulse body 3, a suspension hook 4, at least one insulator 5, a bearing 6 and a ring body 7.This supporter 1 is selected from the preferable metal material of rigidity, for example steel, iron, tungsten or its alloy etc., and this supporter 1 has an accommodation space 10, and for ccontaining this pulley 2, this pulley 2 this supporter 1 is relatively made pivot pendular motion freely.This pulley 2 is provided with several messenger wires 20, for the ease of adjusting the bearing capacity of these lifting facility, each messenger wire 20 is formed by the metal wool braiding that several have rigidity, this messenger wire 20 is controlled by one and rotates facility (not illustrating), a motor for example, so when these rotation facility drive this messenger wire 20, but these pulley 2 rotations of interlock, and then control this supporter 1 and do and move up and down.
Referring again to shown in Figure 2, the accommodation space 10 of the supporter 1 of the utility model first embodiment also can articulate this inverted impulse body 3.This inverted impulse body 3 has an outer peripheral face 30 and an inner peripheral surface 31.This inverted impulse body 3 also as this pulley 2 equally relatively this supporter 1 do pivot pendular motion freely.This inverted impulse body 3 from top to bottom is provided with a through hole that runs through (not indicating) in middle position in addition, and this inner peripheral surface 31 defines and is formed within this through hole.By this, this suspension hook 4 and insulator 5 can be placed within this through hole, and the part of this through hole has the path length of broad, further are placed within this through hole for this bearing 6.This suspension hook 4 is held a pre-welding thing (not illustrating) with constant weight in order to collude, collude and hold intensity in order to increase it, the some of this suspension hook 4 protrudes from outside the through hole of this inverted impulse body 3, and lock by a connecting element 40, and these connecting element 40 preferable nuts that are selected from, so that by screwing togather this suspension hook 4 of locking.In addition, this suspension hook 4 pivots in the through hole of this inverted impulse body 3 for convenience, and this bearing 6 can be selected from a ball bearing of main shaft or a needle bearing, and so this suspension hook 4 can rotate within this through hole freely along with this bearing 6.Simultaneously, in order to strengthen the intensity of lifting facility, this inverted impulse body 3, suspension hook 4, connecting element 40 and bearing 6 all are selected from one and have the preferable metal material of rigidity, for example steel, iron, tungsten or its alloy etc.
Referring again to shown in Figure 2, the insulator of the utility model first embodiment 5 is preferable to be selected from one and to have the splendid material of the characteristic of being electrically insulated, for example Teflon.The one side of this insulator 5 is arranged at the inner peripheral surface 31 of this inverted impulse body 3, and this suspension hook 4 of the another side butt of this insulator 5 and bearing 6, so that intercept the contact condition of this inverted impulse body 3 and suspension hook 4 and bearing 6; In addition, this insulator 5 forms an extension 50 in addition in the end face (not indicating) of this inverted impulse body 3, so that intercept the contact condition between this inverted impulse body 3 and the connecting element 40.This insulator 5 can be integrally formed inner peripheral surface that is arranged on this inverted impulse body 3 31 and end face; Perhaps but layering is incorporated into the inner peripheral surface 31 and the end face of this inverted impulse body 3, so that increase the nargin that this insulator 5 is provided with, and improves the convenience of changing this insulator 5.
Referring again to shown in Figure 2, when colluding, this suspension hook 4 holds this pre-welding thing, when carrying out welding operation, this pre-welding thing need apply a big electric current usually so that carry out this welding operation, this moment, so this big electric current that applies that can insulate further conducted to this messenger wire 20 along outer peripheral face 30, supporter 1 and the pulley 2 of this inverted impulse body 3 because this insulator 5 is arranged between this inverted impulse body 3 and suspension hook 4, connecting element 40 and the bearing 6.By this, this messenger wire 20 can effectively be avoided impact because of the big electric current damage that wrecks.
Referring again to shown in Figure 2, be provided with a ring body 7 between this suspension hook 4 and the insulator 5 in addition, and these ring body 7 preferable metal material that a hardness is higher than the hardness of this insulator 5, for example iron, steel, tungsten and alloys thereof of being selected from.Therefore, when this suspension hook 4 carries out colluding of this pre-welding thing when holding operation, this suspension hook 4 is unlikely the extruding that is subjected to this connecting element 40 because of this insulator 5 and radially oppresses, and then limits the slew mode of this suspension hook 4 in the through hole of this inverted impulse body 3.
Please refer to shown in Figure 3ly, be the insulation structure of the lifting facility of the utility model second embodiment.Compared to first embodiment, second embodiment is provided with this insulator 5 except inner peripheral surface 31 and the part end face at this inverted impulse body 3, further the outer peripheral face 30 in this inverted impulse body 3 is provided with another insulator 5 ', so that intercept the contact condition of this supporter 1 and inverted impulse body 3.By this, hold this pre-welding thing, when carrying out welding operation, be equipped with this insulator 5 and 5 ' between this supporter 1, inverted impulse body 3 and the suspension hook 4, and can further improve insulation effect, to avoid this messenger wire 20 to be subjected to the destruction of big electric current and to rupture when this suspension hook 4 colludes.
As mentioned above, commonly use the lifting facility compared to Fig. 1, when carrying out welding operation, this supporter 90, pulley 91, inverted impulse body 93 and suspension hook 94 directly articulate mutually, to provide this big electric current to conduct to a conductive path of this messenger wire 92, and then causing the charge into shortcomings such as destroying fracture of this messenger wire 92 because of big electric current, the utility model is by this suspension hook 4 and connecting element 40 are provided with the exhausted body 5 of this edge relatively in the inner peripheral surface 31 of this inverted impulse body 3 and end face part; In addition, also can this insulator 5 ' be set at the outer peripheral face 30 of this supporter 1 and inverted impulse body 3, it can effectively intercept between this supporter 1, inverted impulse body 3 and this suspension hook 4 really and directly be in contact with one another state, avoiding this messenger wire 20 to destroy fracture, and then increase working security and improve the facility life-span because of big charging into of electric current.
