Abstract
The utility model discloses an insulating flexible ladder for overhead work, which comprises a flexible ladder and a ladder head, wherein the ladder head comprises a flexible ladder lock catch connected with the flexible ladder, and a pair of cable hooks; cable pulleys are arranged in the cable hooks; annular grooves are formed in edges of the cable pulleys; the ladder head also comprises a rotary fence of which a rotating shaft is connected to a parallel ladder shaft. With the adoption of the insulating flexible ladder for the overhead work disclosed by the utility model, position movement and turning operation of an operator under an aerial cable are convenient, and the labor intensity of the operator is alleviated. The insulating flexible ladder for overhead work disclosed by the utility model is simple and firm in structure, low in cost, convenient to manufacture and high in safety coefficient.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to power equipment installation, particularly a kind of work high above the ground insulated flexible ladder.
Background technology
The installation of high-altitude cable or maintenance need operating personnel in work high above the ground, although can be from the operation of high-tension electricity transmission tower, between two high-tension electricity transmission towers, distance, conventionally up to km on hundreds of, therefore still needs to use insulated flexible ladder.
Insulated flexible ladder generally adopts nylon rope punching, and round crosspiece pipe is combined to form, and its middle rail pipe is as the horizontal step of climbing use.The insulated flexible ladder that is generally used for high-altitude cable operated also comprises for being directly suspended on the terraced head part on the cable of high-altitude, and ladder head is light-weight high-strength material manufacture, for example aluminium alloys.Operating personnel operate high-altitude cable in terraced head part.
Existing insulated flexible ladder ladder head part design comparison is simple, hooks mobile difficulty after the cable of high-altitude, and operating personnel, when high-altitude application, although can fasten safety rope, still easily rock during operation simultaneously, cause operating difficulties.
Utility model content
For the insulated flexible ladder ladder head that the overcomes prior art technological deficiency of operating difficulties in use, the utility model discloses a kind of work high above the ground insulated flexible ladder.
Work high above the ground insulated flexible ladder, comprise rope ladder and terraced head, described ladder head comprises pair of parallel ladder axle, be arranged on the rope ladder snap close for being connected with rope ladder of parallel terraced axle bottom, and the cable hanger that is arranged on parallel terraced axle upper end, in described cable hanger, cable sheave is installed, cable sheave edge has annular groove, and described ladder head also comprises that rotating shaft is connected to the rotation guardrail on parallel terraced axle.
Preferably, described ladder head comprises two rotation guardrails, lay respectively at the differing heights that parallel terraced axle forms the both sides of plane, and vertical separation is greater than 50 centimetres.
Preferably, described rotation guardrail is semicircular arc.
Preferably, described ladder head also comprises the horizontal step being connected on terraced axle.
Preferably, described cable hanger also has for sealing the hook snap close of cable hanger openend.
Preferably, described rotation guardrail has limited block with parallel terraced shaft connection place, makes to rotate guardrail place plane and is no more than 90 degree with parallel terraced axle clamp angle.
Adopt work high above the ground insulated flexible ladder described in the utility model, handled easily personnel are shift position and the operation of turning under the cable of high-altitude, has reduced operating personnel's labour intensity.The utility model is simple in structure firmly, with low cost, convenient manufacture, and safety factor is high.
Accompanying drawing explanation
Fig. 1 is a kind of specific embodiment structural representation of the rope ladder head of a kind of work high above the ground insulated flexible ladder described in the utility model;
In figure, Reference numeral name is called: the horizontal step 3-of the parallel terraced axle 2-of 1-rope ladder snap close 4-rotation guardrail 5-cable sheave.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Work high above the ground insulated flexible ladder described in the utility model, comprise rope ladder and terraced head, described ladder head comprises pair of parallel ladder axle 1, be arranged on the rope ladder snap close 3 for being connected with rope ladder of parallel terraced axle bottom, and the cable hanger that is arranged on parallel terraced axle upper end, cable sheave 5 is installed in described cable hanger, and cable sheave edge has annular groove, and described ladder head also comprises that rotating shaft is connected to the rotation guardrail 4 on parallel terraced axle 1.
During use, rope ladder is connected to terraced head by rope ladder snap close, by strain relief clamp, in the annular groove of cable sheave 5, operating personnel are rotated down rotation guardrail, be rotated guardrail and surround when operating personnel operate, and have increased operating personnel's processing safety.Cable sheave can slide along cable direction, and handled easily personnel change operating position.
Preferably, described ladder head comprises two rotation guardrails, lay respectively at the differing heights that parallel terraced axle forms the both sides of plane, and vertical separation is greater than 50 centimetres.Two not rotation guardrails of homonymy are set, operating personnel can be operated in the both sides of ladder head.Highly differ and be set to be greater than 50 centimetres, make operating personnel no matter in which side operation, as long as pull lower rotation guardrail, can with sitting posture, operate at lower rotation fence, another strong point as handle or while climbing, strengthens operating personnel's psychological security.Rotation guardrail can be arranged to semicircular arc, and operating personnel's position is limited in the nearer safety zone of distance ladder head.On ladder head, at least one can also be set and be connected to the horizontal step 2 on terraced axle, convenient climbing.Rotation guardrail can arrange limited block with parallel terraced shaft connection place, makes to rotate guardrail place plane and is no more than 90 degree with parallel terraced axle clamp angle, and the operation of handled easily personnel sitting posture or climbing are used.On cable hanger, be provided for sealing the hook snap close of cable hanger openend, avoid cable to come off from cable hanger.
Adopt work high above the ground insulated flexible ladder described in the utility model, handled easily personnel are shift position and the operation of turning under the cable of high-altitude, has reduced operating personnel's labour intensity.The utility model is simple in structure firmly, with low cost, convenient manufacture, and safety factor is high.
Previously described is each preferred embodiment of the present utility model, preferred embodiment in each preferred embodiment is if not obviously contradictory or take a certain preferred embodiment as prerequisite, each preferred embodiment arbitrarily stack combinations is used, design parameter in described embodiment and embodiment is only the utility model proof procedure for clear statement utility model inventor, not in order to limit scope of patent protection of the present utility model, scope of patent protection of the present utility model is still as the criterion with its claims, the equivalent structure that every utilization manual of the present utility model and accompanying drawing content are done changes, in like manner all should be included in protection domain of the present utility model.
