Description
Technical field
The utility model relates to a kind of electric pole protection device.
Background technology
At present, the operating personnel is when climbing electric pole, and both feet respectively overlap the footmuff (being commonly called as " pin is climbed ") of an oval arcuation.The footmuff arc is greater than the diameter of electric pole, so footmuff can pack into electric pole easily in level.When upwards climbing, compress with electric pole after footmuff tilts, the operating personnel relies on the frictional force body support weight between footmuff and the electric pole.When upwards climbing, operating personnel's both hands are encircled electric pole with the location, and both feet are alternately upwards climbed.Pin is climbed easily and is come off during climbing, and pin was climbed easily and skidded winter; Because operating personnel's both hands need free-hand operation, both hands are difficult to play the effect that the pulling way up is climbed, and climb inconvenience, also hazardous simultaneously, in case do not hold electric pole tightly, the people just possibly fall from electric pole.Be not suitable for operating personnel's climbing instrument that both hands use when climbing electric pole in the market.
The utility model content
The purpose of the utility model is to provide a kind of electric pole protection device, when being suitable for the operating personnel and upwards climbing with manual manipulation to play the effect of protection health.
For realizing above-mentioned purpose, the electric pole protection device of the utility model comprises hand pole-climbing, telescopic locking mechanism, long pawl, short pawl and length pawl bracing or strutting arrangement; Length pawl bracing or strutting arrangement is connected in said hand pole-climbing top, and telescopic locking mechanism is located on the said length pawl bracing or strutting arrangement, and telescopic locking mechanism includes push rod; Said long pawl is connected on the length pawl bracing or strutting arrangement of said hand pole-climbing one side, and said short pawl is hinged on the length pawl bracing or strutting arrangement of said hand pole-climbing opposite side, and short pawl has closed position and enable possition; When being provided with gap and short pawl between long pawl and the short pawl and being positioned at closed position with long pawl composition opening elliptic arc coil structures; The end that said short pawl closes on long pawl has fixedly connected to the inner side the arc cover plate, and arc cover plate and said long pawl overlapped when short pawl was positioned at closed position; Said short pawl closes on an end of said long pawl through the hinged brace that is provided with of stator, and the other end of brace and the top of said push rod are hinged.
Be connected with safety rope in the said hand pole-climbing.
The front portion of said long pawl is arranged with gum cover.
Said hand pole-climbing bottom is provided with handle.
Said telescopic locking mechanism comprises cylinder barrel, and sliding in the cylinder barrel is provided with described push rod, and the push rod bottom is provided with blind hole, and the bottom of blind hole is provided with spring, and spring is provided with latch segment; Push rod has a latched position, is provided with lock hole with the corresponding cylinder barrel wall of the said blind hole at latched position place, and the aperture of lock hole is greater than the aperture of said blind hole; When spring is in the diastole position outer end of latch segment be positioned at the opening part of blind hole and flush with the outer end of cylinder barrel wall, the inner of latch segment is positioned at blind hole inside simultaneously; The lock hole place is provided with the unlock button of column; The inner of unlock button radially convexes with the banking stop of ring-type, and the external diameter of banking stop is greater than the aperture of blind hole and less than the aperture of said lock hole.
The outside of the length pawl bracing or strutting arrangement at said short pawl place is fixed with short pawl baffle plate.
The utlity model has following advantage:
1. make short pawl be in the enable possition earlier when using, make the opening between short pawl and the long pawl become big, thereby short pawl and long pawl are centered around on the electric pole of user top, this moment, push rod was in the top lifting position under the drive of short pawl; Make short pawl be in closed position again and make the retaining mechanism locking, be fixed in closed position, make short pawl and the long pawl can be by deviating from the electric pole thereby will lack pawl.Spur the hand pole-climbing and can upwards climb this moment.Encircle electric pole with both hands in the past and compare, make both hands play that the pulling way up is climbed and the effect of protection more easily, use very conveniently, solved the safety problem of the upper and lower shaft tower of attendant.
2. the user is when electric pole is upwards climbed; Can safety rope be posted on safety belt between waist, when the user makes a fault when falling downwards, the electric pole protection device of the utility model can be suspended in the user in midair through safety rope; Fall no longer downwards, thereby play the safeguard protection effect.
3. the front portion of said long pawl is arranged with gum cover, can effectively strengthen the frictional force between long pawl and the electric pole, simultaneously long pawl is played a protective role.
4. the person easy to use that is provided with of handle uses held.
5. during release, only need press unlock button.This moment, banking stop was crushed on the cylinder barrel outer wall; The inner of unlock button just pushes away lock hole (the inner and the inner wall of cylinder that are unlock button flush) with latch segment; Owing to no longer stopped by the cylinder barrel wall latch segment at this moment, so latch segment and push rod can slide along the length direction of cylinder barrel.In the above-mentioned releasing process, said spring is compressed.When locking, only need to lack pawl and be reset to closed position, this moment, push rod was promoted to move to latched position by said brace; When latch segment moved to the lock hole place, under the elastic force effect of spring, latch segment jack-up got into lock hole; Thereby the locking push rod makes short pawl be fixed in closed position.Above-mentioned release, locking process are simple and easy to do, very are convenient to operation.The external diameter of banking stop is greater than the aperture of blind hole, and banking stop stretches into and forms locking in the blind hole in the time of can preventing release.
6. lack being provided with of pawl baffle plate and can prevent that short pawl open degree when opening is excessive.
