Invention content
In order to solve the problems in the existing technology, the purpose of this utility model, which is to provide one kind, can be fixed on electric pole Upper power construction construction ladder.
In order to achieve the above-mentioned object of the invention, the utility model uses technical solution as described below:
One kind can be fixed on power construction construction ladder on electric pole, including ladder, crossbeam, arc top beam, ladder lock, anchor ear And safety device, several crossbeams are set between the ladder, are climbed upwards by crossbeam for construction worker, the crossbeam on ladder top For arc top beam, the lower section at arc top beam both ends fixes two elastic strings on ladder, safety belt is fixed among elastic string;Arc The intermediate of shape top beam installs anchor ear, and anchor ear includes anchor ear cross-arm, upper anchor ear and lower anchor ear, upper anchor ear and the opposite formation of lower anchor ear The cavity of similar round is wrapped in by screw bolt and nut cooperation on arc top beam, and anchor ear cross-arm both ends open up threaded hole, pass through spiral shell The cooperation of screw bolt and nut is fixed together with ladder lock cross-arm, and the ladder lock includes ladder lock cross-arm, connecting rod, moon template, rubber, consolidates Determine ring arm, thin stupefied item, flexible ring arm and sleeve, ladder lock cross-arm, which is fixed by the connecting rod, is connected to a moon template bottom(Month template 9 is There is the plate of certain radian), moon template bottom also sets up fixed ring arm, and one end of fixed ring arm is fixed on the bottom of moon template, The other end installation sleeve of fixed ring arm, sleeve be sleeved on it is free to slide in flexible ring arm, it is solid with sleeve under fastening bolt effect Fixed, locking, ring arm of stretching remove the slipper on sleeve, and ring arm inside and the upper surface of moon template are respectively mounted rubber, rubber Corresponding moon template and the part surface of flexible ring arm are designed with thin stupefied item.
Further, the extended length of elastic string is no more than 2/3 height of ladder.
Further, rubber is fixed by sunk screw.
Further, sliding length of the sleeve in flexible ring arm is within 20cm.
Due to the adoption of the above technical scheme, the utility model has following superiority:
The crossbeam on ladder top is designed to that arc top beam, card on utility poles, avoid ladder from rolling, are arranged on crossbeam Anchor ear and ladder lock on utility poles by ladder locking place slide downward when ladder uses, ladder lock surface is designed with thin stupefied Item further increases the safety of construction ladder, is fixed with safety device on the lower section ladder at crossbeam both ends, provides construction worker More one layer of safety guarantee, ladder lock use telescopic structure, adapt to the electric pole of different-diameter, have a wide range of application.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram being fixed on power construction construction ladder on electric pole.
Fig. 2 is a kind of to be fixed on electric pole the structure of anchor ear and ladder lock connection type in power construction construction ladder and show It is intended to.
Fig. 3 is a kind of structural schematic diagram being fixed on anchor ear in power construction construction ladder on electric pole.
In figure:1, ladder;2, crossbeam;3, arc top beam;4, sleeve;5, flexible ring arm;6, thin stupefied item;7, fixed ring arm; 8, rubber;9, moon template;10, connecting rod;11, ladder lock cross-arm;12, anchor ear cross-arm;13, upper anchor ear;14, lower anchor ear;15, elastic Rope;16, safety belt.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.
Please referring to Fig.1~3, in the utility model embodiment, one kind can be fixed on power construction construction ladder on electric pole, Including ladder 1, crossbeam 2, arc top beam 3, ladder lock, anchor ear and safety device, several crossbeams 2 are set between the ladder 1, for applying Work worker is climbed upwards by crossbeam, and the crossbeam on 1 top of ladder is arc top beam 3, the lower section at 3 both ends of arc top beam, in ladder 1 On fix two elastic strings 15, fixed safety belt 16 among elastic string 15;Installation anchor ear, anchor ear include among arc top beam 3, The opposite cavity for forming similar round of anchor ear cross-arm 12, upper anchor ear 13 and lower anchor ear 14, upper anchor ear 13 and lower anchor ear 14, passes through bolt It is wrapped on arc top beam 3 with nut cooperation, 12 both ends of anchor ear cross-arm open up threaded hole, pass through cooperation and the ladder of screw bolt and nut Button cross-arm 11 is fixed together, and the ladder lock includes ladder lock cross-arm 11, connecting rod 10, moon template 9, rubber 8, fixes ring arm 7, is thin Stupefied item 6, flexible ring arm 5 and sleeve 4, ladder lock cross-arm 11 are fixedly connected on 9 bottom of moon template by connecting rod 10(Month template 9 is There is the plate of certain radian), the moon template 9 bottom also set up fixed ring arm 7, one end of fixed ring arm 7 is fixed on the bottom of moon template 9 Portion, the other end installation sleeve 4 of fixed ring arm 7, sleeve 4 be sleeved on it is free to slide in flexible ring arm 5, under fastening bolt effect with Sleeve 4 is fixed, is locked, ring arm 5 of stretching removing slipper on sleeve 4, and on the inside of the ring arm and upper surface of moon template 9 is respectively mounted Rubber 8, rubber 8 are fixed by sunk screw, and the part surface of 8 corresponding months templates 9 of rubber and flexible ring arm 5 is designed with thin stupefied Item.
The operation principle of the utility model is:
When using the utility model, the diameter first according to electric pole is needed, by the flexible ring arm of fastening bolt adjusting and admittedly Determine the distance between ring arm, then on utility poles by the arc top beam 3 on 1 top of ladder card, prevents ladder 1 from rolling, separately It is outer to need electric pole being stuck between the flexible ring arm of ladder lock and fixed ring arm, ladder 1 is moved backward, ladder lock 1 is allowed to be locked at electricity In line bar, construction worker is helped ladder 1 to climb upwards, after touching safety device, safety belt 16 is tied up by crossbeam 2 On the waist of oneself, due to safety belt both ends connecting rope be elastic string 15, even if make worker accidentally fall elastic string if can play Good cushioning effect avoids under the action of inertia, causing worker the discomfort on body;On the other hand, as device makes With the increase of time, rubber 8 can be gradually worn out, and expose the head of sunk screw, reduce the contact surface of rubber 8 and electric pole Product influences the antiskid effect of ladder lock, therefore is both provided with thin stupefied item 6 in ladder lock place corresponding with rubber 8, both plays auxiliary anti-slipping Effect, also ensure safety and the durability of device.
