Description

The bar that falls is turned first

Technical field

The present invention relates generally to power domain, be specifically related to a kind of fall bar to turn first.

Background technology

The electrical power trans mission/distribution system circuit of below 35kV is almost single pole entirely, and they are rod or cement pole.Can't do without stepping on bar operation when the outside line worker construction of line or maintenance circuit, staff is when stepping on bar process or masthead operation, just in case there is pole collapse accident, situation is one act that people do not wish to see.Because have individual tilting procedure before electric pole falls down to the ground, the weight now electric pole likely slided comprises people, all can rotate to the direction of falling bar centered by electric pole under self gravitation effect, finally fixes immediately below tilting bar.When isoelectric line bar falls down to the ground, the forehand of falling bar, in the midline of human body, runs into this thing and more ominous than propitious.

summary of the inventiontechnical problem to be solved by this invention is as follows: the first, have button bar to be coated with electric pole owing to falling the turn proostracum of first of bar, fill a torticollis after rear first to contact to earth long tube, before electric pole does not also fall down to the ground, the long tube that contacts to earth first contacts to earth, rear first diagonal brace power is given in torticollis effect, the human body that the bar that falls is turned in first and first is that axle is turned to above electric pole with electric pole, has escaped the event that bar is hit the person and has occurred.The second, the inner side of proostracum, Hou Jia and right first all arranges reinforcement, and before making, keep fixed position between right, rear three first, protection human body does not crush injury when overturning.Three, all there is cushion owing to falling turn rear side and right side in first of bar, make down bar first of turning play cushioning effect when upset to human body.

In order to solve the problems of the technologies described above, technical scheme of the present invention is:

A kind of fall bar to turn first, it is characterized in that: include the sheet frame armor be made up of proostracum, You Jia, rear first three, described proostracum front is fixed with buckling rod ring, and buckling rod ring is formed closed circular by latch closure; Described rear first rear left side fixes a torticollis by axle key and to contact to earth long tube, and the torticollis long tube that contacts to earth draws aluminium flake acting in conjunction by a Gen Zhila aluminium flake and two, and the straight-tube portion of the long tube that contacted to earth by torticollis keeps vertical with rear first face.

Described fall bar to turn first, it is characterized in that: described is drawn aluminium flake to be flute profile thin slice.

Described fall bar to turn first, it is characterized in that: a described Gen Zhila aluminium flake draws the intensity of aluminium flake only the straight-tube portion of the long tube that contacts to earth need be kept vertical with rear first face, the support strength more than can not having too much with two.

Described fall bar to turn first, it is characterized in that: a described Gen Zhila aluminium flake and two draw wherein one end of aluminium flake to be fixed in rear first, and the other end is fixed on solid pipe ring by screw and puts, and contacts to earth on long tube Gu pipe ring cover is sleeved on torticollis.

Described fall bar to turn first, it is characterized in that: the inner side of described proostracum and You Jia and Hou Jia and You Jia junction respectively arranges two reinforcements.

Described fall bar to turn first, it is characterized in that: described You Jia and rear first are all equipped with thicker cushion.

Described fall bar to turn first, it is characterized in that: inside described rear first, shoulder belt and loins frenulum are hung in installing respectively.

Beneficial effect of the present invention is:

A, electric pole fall down to the ground in process, human body is torqued into above bar below bar, escaped bar hit the person one difficult.

B, between first and first, be provided with reinforcement, ensure that down that bar to turn in process human body from extruding.

C, first inboard bolsters cushion, and reduce to fall bar and to turn first injury to human body when giving play to the function effect.

Detailed description of the invention

As shown in Figure 1, a kind of fall bar to turn first, by sheet frame armor be made up of proostracum 11, right first 4, rear first 8 three, proostracum 11 front is fixed with the buckling rod ring 1 of diameter slightly larger than pole bottom diameter, and this buckling rod ring 1 passes through latch closure 2 and formed closed circular.To be contacted to earth long tube 7 by the torticollis that a high strength lightweight material fixed by axle key 9 in rear first 8 rear left side, contact to earth long tube 7 of this torticollis draws aluminium flake 12 by solid pipe ring cover 6 under holding screw nail 13 is reinforced by draw aluminium flake 5 and two of a thin slice flute profile, makes the contact to earth straight-tube portion of long tube 7 of torticollis keep vertical with rear first 8.Right first 4 and rear first 8 are all equipped with thicker cushion 10.The inner side of proostracum 11 and right first 4 and rear first 8 and right first 4 junction, respectively arrange two reinforcements 3, reinforcement 3 particular location is shown in that B---B view (moving cushion) is namely shown in Fig. 4.To turn the use of first for the ease of falling bar, inside rear first as shown in A---A view and Fig. 3, shoulder belt 14 and loins frenulum 15 are hung in installing respectively.

Light in order to ensure down bar first of turning, require that each component materials of this device is all that high strength is lightweight, but to draw in aluminium flake 5 and Fig. 2 two to draw the intensity of aluminium flake 12 can not be too high as in Fig. 1, in order to avoid play inhibition to falling bar first job function of turning.

The solution of the present invention implementation process is as follows:

Staff can before stepping on bar, bar first of turning of falling as shown in Figure 3 hung shoulder belt 14 and hung on two shoulders, waist is fastened loins frenulum 15; When stepping on bar by the latch closure 2 in Fig. 1 electric pole circle in buckling rod ring 1, relievedly can step on bar.

Staff is when stepping on bar process or masthead operation, once there is pole collapse accident, staff, in the process of falling bar, due to the effect of person gravity, is first torqued into immediately below electric pole toppling direction.When electric pole contacts to earth down to the long tube that contacts to earth after human body, because there is torticollis part long tube upper end, the axle key (as 9 in Fig. 1) at torticollis top is stopped in the left side of rear first, stagger a bit of distance in axle key and the direction of falling bar, this segment distance is under electric pole and the effect of personal fall's power, with electric pole axis for fulcrum forms a moment of torsion, this moment of torsion is easy to just destroy the supporting role of propping up sheet and two pulling-on pieces that intensity is not high originally, and before electric pole lands, human body is torqued into above bar below bar, escaped bar hit the person one difficult.Due to the inner side of proostracum and You Jia and Hou Jia and You Jia junction, respectively arrange two reinforcements (as 3 in Fig. 1), when the long tube that contacts to earth contacts to earth, forward and backward first can keep fixed range, keeps human body and is not squeezed.Cushion (as 10 in Fig. 1) inside Hou Jia and right first plays cushioning effect to human body in twist process, reduces to fall bar and to turn the injury of first function to human body.
