Description
Technical field
The present invention relates to a kind of transmission line high-altitude operation rope ladder connector, the particularly adjustable rope ladder head of a kind of transmission line of electricity.
Background technology
In transmission line of electricity, the operation of overhead wire needs to use rope ladder usually, and the end of rope ladder is referred to as rope ladder head, and rope ladder is connected on circuit by rope ladder head, and then operating personnel climbs up circuit by rope ladder and carries out Job Operations.Rope ladder head of the prior art adopts contour cleat stanchion, is fixed on the line by colligation or other modes such as mounting of sliding.Its weak point is, this feature of first contour cleat stanchion certainly will need circuit to provide contour position to make it easy to connection, which limits the service condition of rope ladder, cannot use as required, bring very large inconvenience; In addition once there is the not isometry position that the discrepancy in elevation is excessive, the side of rope ladder head is just easy to come off from trolley line, brings great personal safety hidden danger to operating personnel.
Summary of the invention
The object of the invention is to provide according to the deficiencies in the prior art part a kind of easy to operate, safety is high, the transmission line of electricity of good reliability is adjustable rope ladder head.
The object of the invention is to be realized by following approach:
Transmission line of electricity is adjustable rope ladder head, its structural feature is, include two adjustable cleat stanchions and pulley gear, every root is adjustable, and cleat stanchion all includes fixing cleat stanchion and movable cleat stanchion, the upper portion hollow of fixing cleat stanchion, and be distributed with the through hole that a plurality of transverse direction runs through vertically, movable cleat stanchion is arranged in the hollow cavity of fixing cleat stanchion, can relatively fix cleat stanchion to move up and down, movable cleat stanchion is distributed with the pin-and-hole corresponding with through hole on fixing cleat stanchion vertically simultaneously, when the through hole on fixing cleat stanchion corresponding with the pin-and-hole on movable cleat stanchion through time, latch can be inserted, thus connect and fixing cleat stanchion and movable cleat stanchion, be installed with pulley gear in the upper end of movable cleat stanchion, pulley gear includes the semi-surrounding inverted U framework that Open Side Down and the pulley installed in the frame, the bottom of fixing cleat stanchion connects operating rope ladder.
Before using, according to the job position of transmission line of electricity, calculate the difference in height needing the two ends of hanger rope ladder head, then adjustment activity cleat stanchion is in the position of fixing cleat stanchion internal cavity, thus adjusts the length of this adjustable cleat stanchion termination, is fixed finally by latch.During use, by the power line of the open side of pulley gear near job position, and make power line enter inverted U framework from opening, frame leans against below pulley, realizes the connection by adjustable rope ladder head and circuit.Main points of the present invention are, adjustment height can be carried out in rope ladder head cleat stanchion upper end.Hanging ladder on the trolley line of the large transmission line of electricity span of the discrepancy in elevation, can turn down the rope ladder post of eminence, make rope ladder head two pulleys be linked into trolley line and to be unlikely to come off.Rope ladder head height can regulate arbitrarily according to trolley line span discrepancy in elevation size, therefore easy to operate, safety is high, good reliability.
The present invention can be specially further:
Also include Manual brake device, it includes brake hand handle, brake shoes and spring catch, spring catch is arranged on the wheel shaft inner chamber of pulley, brake shoes symmetry is arranged on inverted U framework biside plate corresponding to the two sides of pulley, the upper surface of its one end and inverted U framework is hinged, the movable end of spring catch is positioned on the other end side of brake shoes, and brake hand is the fixed end of linking springs pin.
During use, pull brake hand handle, thus spring catch is pressed to brake shoes, make brake shoes press to pulley direction further, under the rubbing action of brake shoes, realize braking action.Thereby, it is possible to can not run toward lower is sliding when guaranteeing that rope ladder head hangs on the large trolley line of the discrepancy in elevation, and rope ladder head can also manually be fixed after rope ladder is moved to job position by brake gear by operating personnel again.
Also include a movable sliding sleeve, it includes movable frame, guide rod and hook-shapedly to seal up a door, described movable frame is by four external members, two treadles and two compression spring set quadrangularly frameworks, wherein each two the external member covers in left and right are through on fixed ladder post following side, for four summits of quadrilateral frame, two treadles are respectively the bottom and upper segment of quadrilateral frame, the two ends of treadle are fixedly connected with left and right external member respectively, two Compress Springs are respectively the left side and the right of quadrilateral frame, and Compress Spring is between two external members of same fixing cleat stanchion; Outside two external members of same fixing cleat stanchion, be provided with guide rod, two external members are run through in guide rod bottom, and top is connected with hook-shaped sealing up a door; Describedly hook-shapedly seal up a door as a kind of rod member of L-type, one end is connected with guide rod top, then extends to another side plate according to the side plate of L-type from inverted U framework, seals closed by the opening of inverted U framework, the other end of L-type rod member, then in hook-shaped, is connected with another side plate of inverted U framework.
During use, operating personnel can step on the top of movable frame by pin, make its top under the elastic force effect of Compress Spring, to close below, drive guide rod to pull simultaneously downwards, drive further and swing as the L-type rod member of sealing up a door, pull the side plate of inverted U framework to press to middle pulley thus, realize braking action, controlling rope ladder head can not slide.Like this, when operating personnel due to operational requirements cannot hand-operated brake fix time, pin can be adopted to touch on the brake.On the other hand, while realization brake is fixing, inverted U framework can also be closed, avoid adjustable rope ladder head in use procedure to jump out of wire, improve safety and the operating reliability of operating personnel.
In sum, the invention provides the adjustable rope ladder head of a kind of transmission line of electricity, main points are, adjustment height can be carried out in rope ladder head cleat stanchion upper end.Hanging ladder on the trolley line of the large transmission line of electricity span of the discrepancy in elevation, can turn down the rope ladder post of eminence, make rope ladder head two pulleys be linked into trolley line and to be unlikely to come off.Rope ladder head height can regulate arbitrarily according to trolley line span discrepancy in elevation size, therefore easy to operate, safety is high, good reliability.
