Description
Technical field
The utility model belongs to electric armour clamp technical field, relates in particular to a kind of novel pair of cross-arm.
Background technology
Cross-arm is part important in shaft tower, is mainly used to installing insulating and gold utensil, with support conductors, lightning conducter, and makes it the safe distance that keeps in accordance with regulations certain; The relatively scattered installation of parts of conventional cross-arm mainly adopts two people's cooperations to carry out, two people are intersected up and down to station, in operation, first need to turn on anchor ear one side bolt, coordinate again from being inserted in outside to inside electric pole, one people's holder is held up, one people twists bolt, on electric pole, in narrow space, complete two people that installation need to install while thering is good tacit degree and fitting operation the moment of attentiveness concentrate, labour intensity is large, dangerous high, in installation process, also should prevent misoperation at any time and cause dropping of workpiece, injure ground auxiliary; First work high above the ground should ensure operator's safety.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of installation to simplify, novel pair of safe cross-arm.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of novel pair of cross-arm, comprises cross-arm A and cross-arm B, and the two ends of described cross-arm A and cross-arm B are all respectively arranged with hook and are connected by tension spring; Described cross-arm A and cross-arm B are symmetrically arranged L-type equal leg angle, and cross-arm A and cross-arm B middle inside are welded respectively and be provided with curved buckle in circular arc excurvation buckle and circular arc, and in described circular arc excurvation buckle and circular arc, curved buckle cooperatively interacts; On the riser of cross-arm A and cross-arm B, be provided with symmetrical interior hexagonal clamping screw; On the transverse slat of described cross-arm A and cross-arm B, all have loose slot.
The two ends of cross-arm A and cross-arm B are all respectively arranged with hook and are connected by spring, cross-arm A and cross-arm B middle inside are welded respectively and are provided with curved buckle in circular arc excurvation buckle and circular arc, the tension spring that is arranged at cross-arm A and two ends, cross-arm B left and right provides auxiliary pulling force that cross-arm A and cross-arm B are linked together, ensure globality, convenient installation, the inside and outside buckle of circular arc can successfully engage when mounted centered by electric pole, and hold tightly on electric pole, one people can easily complete installation, has also saved labour when improving fail safe; On the riser of cross-arm A and cross-arm B, be provided with symmetrical interior hexagonal clamping screw, hexagonal clamping screw in adopting, steps up intensity higher, and the stability that Bidirectional horizontal stretcher is located on electric pole strengthens; On the transverse slat of cross-arm A and cross-arm B, all have loose slot, facilitate installing insulating and gold utensil, and can regulate at any time mounting distance; Integral type is installed and is greatly reduced the possibility that high-altitude workpiece drops, and avoids damaging to ground support staff.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts integral type to install, and step is simplified, and saves labour, and fail safe improves, and has also greatly promoted operating efficiency simultaneously.
Brief description of the drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation that the utility model is overlooked;
Mark in figure: curved buckle 5, interior hexagonal clamping screw 6 and tension spring 7 in cross-arm A1, cross-arm B2, loose slot 3, circular arc excurvation buckle 4, circular arc.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in fig. 1, the utility model is a kind of novel pair of cross-arm, comprises cross-arm A1 and cross-arm B2, the two ends of described cross-arm A1 and cross-arm B2 are all respectively arranged with hook and are connected by tension spring 7; Described cross-arm A1 and cross-arm B2 are symmetrically arranged L-type equal leg angle, and cross-arm A1 and cross-arm B2 middle inside are welded respectively and be provided with curved buckle 5 in circular arc excurvation buckle 4 and circular arc, and in described circular arc excurvation buckle 4 and circular arc, curved buckle 5 cooperatively interacts; On the riser of cross-arm A1 and cross-arm B2, be provided with symmetrical interior hexagonal clamping screw 6; On the transverse slat of described cross-arm A1 and cross-arm B2, all have loose slot 3.
Before installation, tension spring 7 is in relaxed state, first cross-arm A1 and cross-arm B2 are outwards stretched when mounted, adjust curved buckle 5 in circular arc excurvation buckle 4 and circular arc simultaneously, it is engaged centered by electric pole, pack into from top to bottom in electric pole, be adjusted to applicable position, orientation and smooth, in installing, hexagonal clamping screw 6 is locked, loose slot 3 on the transverse slat of cross-arm A1 and cross-arm B2 facilitates installing insulating and gold utensil, and can adjust at any time mounting distance; Left and right tension spring 7 provides auxiliary pulling force, cross-arm A1 and cross-arm B2 are linked together, convenient installation, the inside and outside buckle of circular arc is held tightly on electric pole and plays orientation, hexagonal clamping screw 6 in installation that now can be convenient, hexagonal clamping screw 6 in using, the intensity of stepping up is higher, and the stability that Bidirectional horizontal stretcher is located on electric pole strengthens; Integral type is installed, and step is simplified, and fail safe is higher, and a people can complete, and saves labour, effectively increases work efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
