Description

A kind of lift safety climbing ladder

Technical field

This utility model relates to a kind of power equipment maintaining aid, specifically a kind of lift Safety climbing ladder.

Background technology

In prior art, in order to prevent non-operating personnel from stepping on bar, existing switch lever, disconnecting link bar, Fall opening lever, the cat ladder lowermost end of cable pole installation requires away from ground to be 2.5 meters, during maintenance activity, Repair personnel needs first to step on bar with climbers, changes climbers again and climb along cat ladder behind cat ladder position Stepping on, this can waste emergency repair time, delayed repairing progress, additionally run into rain, avenge, frost etc. is disliked During bad weather, electric pole is wet and slippery, and operating personnel utilizes climbers easily to skid when stepping on bar, exists from height The security risk fallen in place, carries out rushing to repair operation if erect one section of cat ladder in electric pole bottom, though So can ensure that repair personnel's safety steps on bar smoothly, but lift one section of cat ladder and carry out repairing work everywhere Industry can additionally consume the muscle power of operating personnel, easily causes operating personnel tired, special rural power grids Mostly it is in the fields, lifts cat ladder and further increase the arduous of repair personnel.

Utility model content

The purpose of this utility model is to provide a kind of lift safety climbing ladder, last by cat ladder One joint transform liftable form as, utilizes pull bar to put down, the most then hang up during repairing, operation letter Just and effectively eliminate safe hidden trouble, saved repair personnel and stepped on the bar time, be effectively ensured rush to repair into Degree.

The purpose of this utility model is achieved through the following technical solutions:

A kind of lift safety climbing ladder, including fixing cat ladder and lifting cat ladder, fixing cat ladder is fixed On electric pole, described lifting cat ladder cat ladder fixing with lowermost end one joint is slidably connected, described lifting Cat ladder bottom is hinged with hook, and when described lifting cat ladder rises, the hook on lifting cat ladder is hung On the cat ladder crossbeam of the fixing cat ladder of lowermost end one joint.

Each side plate top of described lifting cat ladder is equipped with two bending clamps, and said two is rolled over Curved clamp is stuck on two edges of fixing cat ladder side plate.

Space is left, when lifting cat ladder slides, on fixing cat ladder between said two bending clamp Cat ladder crossbeam passed by the space between two bending clamps.

When lifting cat ladder and falling completely, described bending clamp is stuck in fixing cat ladder bottom.

Described hook bottom is hinged on the crossbeam of described lifting cat ladder bottom, at described hook Top is provided with flap.

Described lifting cat ladder drives lifting by a pull bar, and described tie rod end is inserted into described In flap.

Described hook is provided with safe direction board.

The bottom of described lifting cat ladder is provided with pedal position.

Fixing cat ladder is fixed on electric pole by anchor ear.

Advantage of the present utility model with good effect is:

1, this utility model transform the final section of last cat ladder as liftable form, repairing Shi Liyong pull bar puts down, the most then hang up, easy and simple to handle and effectively eliminate safe hidden trouble, and saves Repair personnel steps on the bar time, and repairing progress be effectively ensured.

2, this utility model simple in construction, easy for installation and connect reliable.

3, hook of the present utility model is arranged on lifting cat ladder by anti-theft bolt, the most anti- Only there is theft Loss in hook.

Wherein, 1 is electric pole, and 2 is lifting cat ladder, and 3 is fixing cat ladder, and 4 is anchor ear, and 5 are Hook, 6 is safe direction board, and 7 is flap, and 8 is cat ladder crossbeam, and 9 is bending clamp, 10 For pull bar, 11 is pedal position.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in figures 1-4, this utility model includes fixing cat ladder 3 and lifting cat ladder 2, Gu Determining cat ladder 3 to be fixed on electric pole 1 by anchor ear 4, described lifting cat ladder 2 saves with lowermost end one Fixing cat ladder 3 is slidably connected, and described lifting cat ladder 2 bottom is hinged with hook 5, such as Fig. 2 institute Showing, when described lifting cat ladder 2 rises, the hook 5 on lifting cat ladder 2 hangs over lowermost end one On the cat ladder crossbeam 8 of the fixing cat ladder 3 of joint.

As it is shown on figure 3, be equipped with two bendings on each side plate top of described lifting cat ladder 2 Clamp 9, said two bending clamp 9 is stuck on two edges of fixing cat ladder 3 side plate, So lifting cat ladder 2 just can slide on fixing cat ladder 3, and fixes cat ladder 3 when sliding On cat ladder crossbeam 8 passed by the space between two bending clamps 9, when lifting cat ladder 2 complete When entirely falling, described bending clamp 9 is stuck in fixing cat ladder 3 bottom, thus ensures to lift cat ladder 2 do not depart from fixing cat ladder 3.

As in figure 2 it is shown, described hook 5 bottom is hinged on the horizontal stroke of described lifting cat ladder 2 bottom Liang Shang, is provided with flap 7 on described hook 5 top, and as shown in Figure 4, operating personnel utilizes one Individual pull bar 10 makes described lifting cat ladder 2 rise or put down, and described pull bar 10 end is inserted into institute Stating in flap 7, on the one hand operating personnel can lift lifting cat ladder 2 by pull bar 10, separately On the one hand hook 5 can also be hung over the cat ladder of fixing cat ladder 3 by operating personnel by pull bar 10 On crossbeam 8.

As in figure 2 it is shown, be provided with safe direction board 6 on described hook 5, climb in described lifting The bottom of ladder 2 is provided with pedal position 11, and when lifting cat ladder 2 and putting down completely, operating personnel can With step on described pedal position 11 climb up lifting cat ladder 2.Hook 5 of the present utility model is by anti- Steal bolt to be arranged on lifting cat ladder 2, effectively prevent from linking up with 5 generation theft Loss, institute State anti-theft bolt and be known in the art technology.
