Embodiment
The utility model discloses a kind of device being applied to Maintenance of Electric Transmission Line, staff's climbing trees can be avoided, thus the Personal Safety of the staff when safeguarding transmission line can be improved.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, in a kind of embodiment that Fig. 1 provides for the application, be applied to the structural representation of the device of Maintenance of Electric Transmission Line.
In this embodiment, be applied to the device of Maintenance of Electric Transmission Line, comprise insulating bar 1 and clamping element, wherein insulating bar 1 is made up of insulating material; Clamping element comprises the first clamping section 2 and is hinged at both cross-point locations places with intersect the second clamping section, clamping section 3, first 2 of arranging and the second clamping section 3, the first clamping section 2; The pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section is oppositely arranged and the inwall of the inwall of the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section forms clamp port, link 2b and the insulating bar 1 of the first clamping section are fixedly connected, and the link 3b of the second clamping section is connected with insulating cord 8.
So, by clamping element is connected with insulating bar 1, when carrying out the felling of branch, staff only needs to lift insulating bar 1, clamping element can be sent to the branch position place to being positioned at eminence, owing to forming clamp port between the pinching end 2a of the first clamping section of clamping element and the pinching end 3a of the second clamping section, this clamp port, for holding the limb of branch, plays the effect of fixing branch.To be clamped, with after branch fixes, pulls insulating cord 8, under the effect of insulating cord 8, clamping element and branch can be driven to topple over to the direction away from transmission pressure.Compared with staff's climbing trees in prior art, staff utilizes the device being applied to Maintenance of Electric Transmission Line provided in this programme to stand on ground and can pull branch and topple over to the direction away from transmission pressure, owing to not needing climbing trees, the Personal Safety of the staff when safeguarding transmission line therefore can be improved.
It should be noted that, in this embodiment, due to the first clamping section 2 and the second clamping section 3 intersect setting and both be hinged in crosspoint, so in the process pulling insulating cord 8, the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section can move towards near the direction of the other side, the clamp port that the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section is formed can reduce thereupon, thus can ensure that branch is securely placed in the space that above-mentioned clamp port formed in the process pulling insulating cord 8.
Also it should be noted that, in this embodiment, insulating bar 1 is plastic insulation bar etc., and the intensity of insulating bar should meet the demand of use, and the length of insulating bar 1 can be arranged according to the environment for use of reality and situation simultaneously.
Further in scheme, the inwall of the pinching end 2a of the first clamping section caves in towards the direction of the pinching end 3a away from the second clamping section, the inwall of the pinching end 3a of the second clamping section caves in towards the direction of the pinching end 2a away from the first clamping section, and the inwall of the inwall of the first pinching end stepped up and the pinching end 3a of the second clamping section forms circular clamp mouth.Because the cross section of the limb of branch is generally circular cross section, therefore clamp port is set to circular clamp mouth and can increases contact-making surface between clamp port and branch, and then can ensure that, in the process pulling insulating cord 8, limb is anchored in the space that clamp port formed.
In addition, in this embodiment, for the ease of delimbing, the inwall of the inwall of the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section is provided with blade.So carrying out pulling in the process of insulating cord 8, pinching end 2a in the first clamping section and the pinching end 3a of the second clamping section can move near the direction of the other side, blade can act on a bar, under the effect of blade, limb can be pruned away from trees, thus staff can be avoided further to carry out work high above the ground, improve the Personal Safety of staff.
Hereinbefore, mainly the set-up mode of clamping element is described in detail, is described to the set-up mode of miscellaneous part below.
In this embodiment, the device being applied to Maintenance of Electric Transmission Line also comprises Flexible Connector 4, one end of Flexible Connector 4 is connected with the outer wall of the pinching end 2a of the first clamping section, and the other end of Flexible Connector 4 is connected with the link 3b of the second clamping section.So, by arranging Flexible Connector 4, Flexible Connector 4 plays the effect of support first clamping section 2 and the second clamping section 3, ensure when not pulling insulating cord 8, the clamp port that the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section is formed is that the pinching end 3a being in the folding condition i.e. pinching end 2a of the first clamping section and the second clamping section is not engaged mutually, clamp port has the opening that the limb for branch is passed, thus can ensure that limb can enter in the space that clamp port surrounds; When carrying out pulling insulating cord 8, the pinching end 2a of the first clamping section and the pinching end 3a of the second clamping section moves towards the direction of the other side, now the pinching end of the first clamping element and the pinching end of the second clamping element are engaged mutually, form the clamp port closed, extended state can be at Flexible Connector 4, now Flexible Connector 4 can apply active force to the first clamping section 2 and the second clamping section 3 respectively, thus ensure the limb of branch to be anchored in closed clamp port, thus limb is prevented to be separated with insulation mouth in the process pulling insulating cord 8.
