Description

Pole centralizer

technical field

The utility model relates to an electric power construction tool, in particular to an auxiliary device for erecting electric poles.

Background technique

In electric power construction, to erect a pole is generally to place one end of the pole obliquely into the pole pit by manpower, then bind the other end of the pole with a steel wire rope, and pull up the pole vertically into the pole pit by manpower. , this method uses more people, labor intensity is big, safety factor is low, and is not suitable for the situation that workload is bigger. In addition, the erected pole can also be directly erected at the pole end by a crane, which is easy to fall off, causing damage to the pole and affecting the service life of the pole.

Utility model content

The technical problem to be solved by the utility model is to provide a pole centralizer, which has the characteristics of good holding effect, easy lifting, safety, time saving and labor saving.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The pole centralizer includes two semicircular steel hoops, the two ends of the semicircular steel hoops are bent outwards to set mounting ears, and a fastener is connected between the opposite mounting ears of the two semicircular steel hoops. Each of the outer sides of the middle part of the semicircular steel hoop is welded with a ring for easy lifting.

The further improvement of the utility model is that: the inner arc radii of the two semicircular steel hoops are equal, the sum of the two inner arc radii is less than the outer diameter of the top of the pole, and the inner sides of the two semicircular steel hoops are respectively provided with at least A non-slip and wear-resistant non-slip mat.

The further improvement of the utility model is that one side of the anti-slip mat is connected to the inner arc of the semicircular steel hoop, and the other side of the anti-slip mat is an arc whose radian is equal to that of the inner arc of the semicircular steel hoop structure.

A further improvement of the utility model is that: the mounting ear is provided with a threaded hole, and the fastener includes a screw corresponding to the threaded hole and a nut matched with the screw.

The further improvement of the utility model is that: the suspension ring is welded at the center of the outer arc of the semicircular steel hoop.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The two semicircular steel hoops of the utility model are put on the top of the electric pole, and the semicircular steel hoops are fastened by the screw rod of the fastener and the screw cap. and is smaller than the outer diameter of the pole, and the inner side of the semicircular steel hoop is provided with an anti-skid pad, so the semicircular steel hoop will be tightly locked with the pole, and the phenomenon that the pole and the steel hoop will not fall off will not occur. In addition, the electric pole is hoisted directly to the two suspension rings by the crane hook and put into the pole pit, which saves time and effort, and there is no potential safety hazard.

The lifting ring is welded at the center of the arc of the semicircular steel hoop. When the crane passes through the lifting ring to erect the pole, the force on the pole will be uniform, and the pole will not be tilted. It is easy to put the pole vertically into the pole pit.

Detailed ways

Below in conjunction with embodiment the utility model is described in further detail:

The pole centralizer, whose structure is shown in Figure 1 and Figure 2, includes two semicircular steel hoops 2, the inner arc radii of the semicircular steel hoops 2 are equal, and the sum of the two inner arc radii is less than the electric pole The outer diameter of the top, two semicircular steel hoops 2 inner sides are respectively provided with 2 anti-slip and wear-resistant anti-slip pads 5, one side of the anti-slip pads 5 is connected on the inner arc of the semi-circular steel hoop 2, the anti-slip pads 5 The other side is an arc structure whose radian is equal to the arc radian of the inner circle of the semicircular steel hoop 2 .

Both ends of the semicircular steel hoop 2 are bent outwards to set mounting ears, and threaded holes are set on the mounting ears. A fastener is connected between the opposite mounting ears of the two semicircular steel hoops 2 , and the fastener includes a screw 1 corresponding to the threaded hole and a nut 4 matched with the screw 1 . The outer sides of the two semicircular steel hoops 2 middle parts are respectively welded with a lifting ring 3 that is convenient for lifting, and the lifting ring 3 is located at the center of the semicircular steel hoop 2 outer arcs.

Two semicircular steel hoops 2 with the same inner arc radius are set on the top of the pole, and the semicircular steel hoop 2 is tightly held by the screw 1 and nut 4 of the fastener that can adjust the length, and then lifted by a crane After hooking to two lifting rings 3 respectively welded at the arc centers of the two semicircular steel hoops 2, the electric pole is lifted and put into the pole pit, which saves time and effort, and has no potential safety hazard.
