Abstract
The utility model discloses a multifunctional pole pit device for circuit training. The device comprises a vertical pole pit formed by concrete pouring and a pole fastening device arranged on a vertical pole pit. The vertical pole pit comprises a right-angle trapezoid pit body on the upper portion and a cylindrical pit body on the lower portion, the inclined waist face of the right-angle trapezoid pit body is located on the side face, and the short edge face of the right-angle trapezoid pit body right faces the top face of the cylindrical pit body. The pole fastening device is of a groined frame structure and located above the cylindrical pit body, and the inner side of shape steel on the front side and the inner side of shape steel on the rear side are respectively provided with an arc-shaped supporting frame. When an overhead wire is electrified and a pole needs to be additionally arranged in the span length of two poles, the wire is lifted 700mm firstly, when the multifunctional pole pit device is used, the root portion of the pole is 2 meters underground, namely, the bottom end of the pole is at the bottom of the pole pit, and a safety distance of 700mm is kept between the top of the pole and the electrified wire after the pole is erected, and therefore safety guarantees are provided for a training electrified vertical pole.
Description
Technical field
The utility model relates to a kind of based on multi-functional electric pole foundation ditch device for the circuit training.
Background technology
Traditional overhead wire vertical rod skills training need to be made a call to a foundation ditch usually on the ground.Comparatively laborsaving when digging a pit, hole, etc. in afield, to take half an hour and just can dig out a diameter 500mm, 2 meters dark columniform foundation ditches, vertical rod training on the same day needs landfill foundation ditch, smooth location after finishing.But for making a call to just so uneasy thing of a foundation ditch on cement or asphalt surface, certainly, in inside, training base, make a call to an electric pole foundation ditch, can run into equally the problems such as excavation difficulty and remaining native contaminated environment!
Therefore, how making the electric pole foundation ditch be convenient to the training use is the stubborn problem of pendulum in face of the circuit professional and technical personnel.
While being accepted without the imagination of cutting the earth when actual training vertical rod, a prefabricated electric pole foundation ditch blank is about to appear in one's mind before eyes, that uses columniform foundation ditch of concreting exactly, the inspection well cover of the internal diameter 500mm of a circle on upper cover, just can be used this diameter 500mm, 2 meters dark foundation ditches as long as open inspection well cover during vertical rod; In the time of in electric pole is placed into this foundation ditch, periphery is as long as keep under control with wedge shape hardwood piece, this " hanging type " vertical rod mode just is adapted to the accessible or power failure vertical rod construction of electric pole overhead, electricity is arranged and will in the span of two electric poles, add a vertical electric pole once upper hollow wire, this columniform foundation ditch does not just adapt to the training needs so, reason is that upper strata has electric lead can not be lifted very highly (general 700mm-1000mm), the electric pole ending will penetrate two like this has in the middle of electric wire, and safe construction is brought to adverse influence.
Summary of the invention
The purpose of this utility model, provide a kind of simple in structure, easy to use based on multi-functional electric pole foundation ditch device for the circuit training exactly in order to address the above problem.
The purpose of this utility model is achieved in that
Of the present utility model a kind ofly it is characterized in that based on multi-functional electric pole foundation ditch device for the circuit training, described multi-functional electric pole foundation ditch device comprises the vertical rod foundation ditch formed by concreting and is located at the electric pole fastener on described vertical rod foundation ditch, wherein:
Described vertical rod foundation ditch comprises superposed right-angled trapezium body foundation ditch and is positioned at the cylinder foundation ditch of bottom, and the oblique girdle plane of described right-angled trapezium body foundation ditch is positioned at side, and its minor face face is right against the end face with described cylinder foundation ditch;
Described electric pole fastener is the well cabinet frame structure be fixedly connected into by four shaped steel, and be positioned at described cylinder foundation ditch directly over, wherein, the shaped steel that is positioned at left and right side is fixed in respectively the near coal-mine left and right side of described right-angled trapezium body foundation ditch accordingly, is positioned on the inboard of shaped steel of forward and backward side and is respectively equipped with a circular arc carriage.
Above-mentioned a kind of based on multi-functional electric pole foundation ditch device for the circuit training, wherein, the diameter of described cylinder foundation ditch is 500mm, and the degree of depth is 50cm.
Above-mentioned is a kind of based on multi-functional electric pole foundation ditch device for the circuit training, and wherein, the angle α of described right-angled trapezium body foundation ditch oblique girdle plane and minor face face is 135 °, and the height of its right angle central plane is 170cm.The right-angled trapezium right-angled trapezium
Electricity is arranged and will in the span of two electric poles, add a vertical electric pole time at upper hollow wire, wire is lifted 700mm in advance, while adopting the utility model vertical rod, the root of electric pole is on ground below 2 meters, be that the electric pole bottom is when the utility model bottom, erect rear bar slightly apart from there being electric lead can also keep the safe distance of 700mm when electric pole, training so charged vertical rod has just had safety guarantee.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, the utility model, based on multi-functional electric pole foundation ditch device for the circuit training, comprises the vertical rod foundation ditch formed by concreting and is located at the electric pole fastener 3 on the vertical rod foundation ditch, wherein:
The vertical rod foundation ditch comprises superposed right-angled trapezium body foundation ditch 1 and is positioned at the cylinder foundation ditch 2 of bottom, and the oblique girdle plane of right-angled trapezium body foundation ditch 1 is positioned at side, and its minor face face is right against the end face with cylinder foundation ditch 2;
The diameter of cylinder foundation ditch 2 is 500mm, and the degree of depth is 50cm.
The angle α of right-angled trapezium body foundation ditch 1 oblique girdle plane and minor face face is 135 °, and the height of its right angle central plane is 170cm.
During charged vertical rod, first electric pole is positioned on the oblique girdle plane of right-angled trapezium body foundation ditch 1 in the mode tilted, when the bottom of electric pole arrives the bottom of right-angled trapezium body foundation ditch 1, electric pole is slowly vertical, and by electric pole fastener 3, electric pole root is anchored on to the center of its well cabinet frame structure, and the arc part of circular arc carriage 33 is close on the outer wall cambered surface of electric pole, guaranteed the vertical steadiness of electric pole.
When by external diameter 45mm, long 2 meters put into right-angled trapezium body foundation ditch 1 and when in addition fastening, quietly be born in the basis that steel tube poles nursery uses with flange basal plane steel pipe pile.
