Abstract
The utility model discloses a dual-opening derrick cap, and relates to the technical fields of transmission and distribution line construction, mounting and teaching tools. Two base sleeves are fixedly connected to the lower end face of a connecting plate. The upper end face of the connecting plate is fixedly connected with two hook plates which are connected through a connecting pillar. Duck mouth-shaped openings are formed in the left and right upper corners of the hook plates. Locking holes are formed in the hook plates above the duck mouth-shaped openings. One end of each cambered locking part is hinged with the connecting pillar below the corresponding duck mouth-shaped opening, and the other end of each cambered locking part is a free end in which a through hole is formed. Due to the use of the derrick cap, an electric pole and a derrick can be separated in a pole erection process, and the electric pole can be firmly fixed on a towing ring particularly in the removing and lowering processes of the electric pole. The dual-opening derrick cap has the characteristics of high safety and reliability.
Description
Technical field
The utility model relates to electric line construction, installation, teaching aid technical field, relates in particular to a kind of twoport pole cap.
Background technology
Reinforced concrete pole is widely used at electric line, and the group pole erecting is one of power supply enterprise's power transmission and distribution specialty routine work project, and workload is big, the technical requirements height, and the operation number is many, and is dangerous big.Because electric pole weight is heavier, be again a kind of slender member, dangerous big in high-altitude installation and the lifting process, needed Work tool is many, need work compound in many ways during operation, technical difficulty is big, and operation technique requires high, in the vertical rod process, if use formula " people " the word pole that falls to come vertical rod and remove discharge lever, must use the pole cap, old-fashioned pole cap pole in the lifting process is asynchronous with the electric pole disengaging, makes the vertical rod process imperfect.
The utility model content
Technical problem to be solved in the utility model provides a kind of pole cap that pole and electric pole are broken away from synchronously.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of twoport pole cap, it is characterized in that two base sleeves are fixedly connected on the lower surface of junction plate, the upper surface of described junction plate is fixedly connected with two hanger plates, connect by joint pin between the hanger plate, the upper left corner and the upper right corner of described hanger plate are provided with opening, the hanger plate of described opening top is provided with obturator hernia, the joint pin of one end of arc latching member and opening below is hinged, and the other end is free end and which is provided with through hole.
Preferably: be fixedly connected with stiffener between hanger plate and the junction plate.
Preferably: be provided with safety collar between two base sleeves, described safety collar is fixed on the lower surface of described junction plate.
The beneficial effect that adopts technique scheme to produce is: carrying out electric pole when standing up operation, the tow lug of " a 8 " font is enclosed within the opening, one end of " 8 " font tow lug connects the required electric pole that stands up by wire rope, the other end connects power end by haulage cable, when electric pole stood up 70 ° of left and right sides, " 8 " font tow lug was deviate from from opening, and at this moment pole can come off synchronously, finish electric pole and stand up, make the vertical rod process complete.In the process of vertical rod, also need to use a safety rope to be connected with safety collar on the pole cap, can prevent that the unexpected landing of pole from causing security incident.Fell when operation carrying out electric pole, " 8 " font tow lug was placed in the opening, closed the arc latching member at two ends, prevented that " 8 " font tow lug from deviating from from opening, caused security incident.By using described pole cap, electric pole and pole can break away from synchronously in the process of vertical rod, and have safety and high reliability features.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1;
Wherein: 1, base sleeve 2, hanger plate 3, safety collar 4, opening 5, obturator hernia 6, arc latching member 7, stiffener 8, junction plate 9, joint pin.
The specific embodiment
Shown in Fig. 1-2, a kind of twoport pole cap, two base sleeves 1 are fixedly connected on the lower surface of junction plate 8, the upper surface of junction plate 8 is fixedly connected with two parallel hanger plates 2, keep certain distance between the hanger plate, be fixedly connected with stiffener 7 between hanger plate 2 and the junction plate 8, be used for increasing the intensity of connection, connect by joint pin 9 between the hanger plate 2.The upper left corner of hanger plate 2 and the upper right corner are provided with opening 4, and the hanger plate 2 of described opening 4 tops is provided with obturator hernia 5, and the joint pin of an end of arc latching member 6 and opening 4 belows is hinged, and the other end is free end and which is provided with through hole.Be provided with safety collar 3 between two base sleeves 1, described safety collar 3 is fixed on the lower surface of described junction plate 8.
Stand up when operation carrying out electric pole, at first, at the head of pole and fixing, this moment, the arc latching member was not with closure of openings with two base sheath jacket casings.Secondly, " a 8 " font tow lug is enclosed within the opening 4, an end of " 8 " font tow lug connects the required electric pole that stands up by wire rope, and the other end connects power set by traction steel wire.Again, respectively with the safety collar on two wire rope connection pole caps, the wire rope of pulling power end, when electric pole stands up 70 ° of left and right sides, " 8 " font tow lug is deviate from from opening 4, hold the wire rope be connected with safety collar simultaneously and prevent that the unexpected landing of pole from causing security incident, with the pole ground of falling.The steel wire that tightens up " 8 " font tow lug power end at last stands up electric pole to 90 ° and finishes the process that electric pole stands up.
Fell when operation carrying out electric pole, at first " 8 " font tow lug was placed in the opening, and used the arc latching member with closure of openings then, prevented that " 8 " font tow lug from deviating from from opening, caused security incident.Then, the wire rope at operation " 8 " font tow lug two ends and the wire rope on the safety collar are put into electric pole.
Used specific case herein principle of the present utility model and embodiment thereof are set forth, the explanation of above embodiment is just with helping understand method of the present utility model and core concept thereof.Should be pointed out that for the person of ordinary skill of the art, can also carry out some improvement and modification to the utility model under the prerequisite that does not break away from the utility model principle, these improvement and modification also fall in the protection domain of the utility model claim.
