Description
Technical field
The utility model relates to electric line construction Work tool technical field.
Background technology
In order to guarantee the safety of electric line operation, effectively prevent inoperative personnel's climbing, the cat ladder of the electric line in many urban districts or suburb is overhead higher, can reach 2-3 rice even higher, has brought great inconvenience for staff's the bar operation of stepping on.Inconvenience is being transported, carried to traditional method of ascending a height because common ladder is comparatively heavy, as using common ladder; And stepping on the bar operating personnel in use needs to carry out operation down the auxiliary of another staff, during climbing not only ladder rock greatlyyer, waste time and energy, ladder is also had relatively high expectations to the smooth degree on ground simultaneously, it is inconvenient to use, and has potential safety hazard.
For addressing this problem, CN 201763223U discloses a kind of electric pole hanging ladder, left and right two straight edge frames are arranged, between two straight edge frames, be evenly equipped with the pedal bar vertical with straight edge frame, the hook towards the same side is arranged respectively in the upper end of two straight edge frames, the quarter butt towards this same side is arranged respectively in the lower end of two straight edge frames, quarter butt is vertical with straight edge frame, the outer end of quarter butt is connected with the arc gripper shoe, and the both sides of arc gripper shoe have journal stirrup respectively, and circular hole is arranged on the journal stirrup.The upper end is hooked on the electric pole during use, and lower end arc gripper shoe is against electric pole, with rope the arc gripper shoe is bundled in the lower end of electric pole, uses safety and does not need other people to assist and can step on the bar operation.But because volume is big, transports, carry still inconvenience, and use more loaded down with trivial details.
The utility model content
The technical problems to be solved in the utility model provides a kind of mobile portable cat ladder, has advantages such as in light weight, easy to use and carry, flexible, safe, has significantly improved operating efficiency and safety when electric line is stepped on the bar operation.
Technical solution adopted in the utility model is: a kind of mobile portable cat ladder, comprise grab, and the lower end bracing frame, single lever-type cat ladder main body is distributed with left and right sides pedal on the single lever-type cat ladder main body.
Pedal is the pin nail, and there is arc angle upwards in the outside of pin nail.
Single lever-type cat ladder main body is collapsible or loose joint formula structure.
The accordion structure of single lever-type cat ladder main body is: two steel pipe hinge connection, and the end of two steel pipes is equipped with U-shaped groove, and junction plate is by two axles and two U-shaped groove hinge connection, and the outside is with the packaged type locating sleeve.
The loose joint formula structure of single lever-type cat ladder main body can be that two steel pipes connect by nipple, also can be the loose joint nut connections etc. of two steel pipes.
The lower end bracing frame is: be welded with little steel pipe on the arc, the lower end of single lever-type cat ladder main body is welded with vertical support bar, and connection is cut with scissors mutually with the outer end of little steel pipe in the outer end of vertical support bar, and is provided with postive stop baffle.
The beneficial effect that adopts technique scheme to produce is: the mobile portable cat ladder has advantages such as in light weight, easy to use and carry, flexible, safe, has significantly improved operating efficiency and safety when electric line is stepped on the bar operation.Because the mobile portable cat ladder is single lever-type, collapsible, volume is little, thereby is convenient to transport and carry; Because easy to assembly, during operation, the mobile portable cat ladder is assembled the suspension that puts in place only needed for 10 times in second, and only needed can climb according to normal climbing posture, did not need personnel auxiliary, thereby better convenient and swift in use again; In addition, when the mobile portable cat ladder is suspended on the electric line cat ladder, can be firm be stuck in above, the lower end bracing frame leans against the lower end of electric line electric pole, there is arc angle upwards in the outside of pin nail, can guarantee like this mobile portable cat ladder hang up the back about, all can not skid up and down, controllability is good, amplitude of fluctuation is very little, step on the bar operating personnel and can keep balance, and mobile portable cat ladder intensity is big, can bear a gross weight of stepping on bar operating personnel and entrained instrument, material fully, safe and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
