Description

A cross-arm replacement tension-resistant installation frame

【Technical field】

The invention relates to a cross-arm mounting frame, in particular to a cross-arm replacement tension-resistant mounting frame.

【Background technique】

As is known, tension-resistant cross-arms are set on both sides of the upper part of the utility pole, and the porcelain bottle is supported by the tension-resistant cross-arm. The overhead wire is fixed on the cross-arm to form a utility pole. When the tension-resistant cross-arm is old or rusted, it needs to be replaced. Tension-resistant cross-arm, because both sides of the tension-resistant cross-arm extend too long, so it is very difficult to fix the hoops on the opposite sides of the two cross-arms to the utility pole, and the personnel under the pole can hardly help.

【Content of invention】

In order to overcome the deficiencies in the background technology, the present invention discloses a cross-arm replacement tension-resistant installation frame. The invention uses the cooperation of the grooved wheel, the lower slotted plate and the personnel under the pole to quickly complete the replacement of the tension-resistant cross-arm .

In order to realize the above-mentioned purpose of the invention, the present invention adopts following technical scheme:

A cross-arm replacement tension-resistant installation frame, including a semicircle on one side, a semicircle on the other side, a slide plate, a sheave and a lower slotted plate, a semicircle on one side, and a side extension plate at the butt end of the semicircle on the other side. The hoop is provided with intubation tubes on both sides of the outer edge of the hoop, and the positioning screw passes through the outer walls of the two intubation tubes and then pushes against the middle of the two slide plates in the two intubation tubes. A lower slotted plate is respectively provided at the lower ends of the two slide plates. , the outer sides of the upper parts of the two skateboards are respectively provided with wheel seats, and the two wheel seats are respectively provided with sheaves.

The cross-arm replaces the tension-resistant installation frame, and the upper and lower sides of the two wheel seats are fixed on the upper outer side of the slide plate by connecting screws, and the shaft of the sheave is passed on the wheel seats.

The cross-arm replaces the tension-resistant installation frame, and two adjustment holes with internal threads are arranged on the outer wall of the two intubation tubes, and the positioning screw passes through the adjustment holes and pushes against the outside of the middle part of the slide plate.

Due to the adoption of the above-mentioned technical scheme, the present invention has the following beneficial effects:

The cross-arm replacement tension-resistant installation frame according to the present invention uses a sheave to make the personnel under the pole pull the rope, so that the two cross-arms can be quickly put on the pole and positioned, and the personnel on the pole can position the hoops of the two cross-arms through the lower slotted plate. The replacement of the tension-resistant cross-arm can be completed quickly; when the invention replaces the tension-resistant cross-arm, the staff on the pole is relatively relaxed; the structure of the invention is simple and practical.

Fig. 2 is a structural representation of a semicircle on one side and a semicircle on the other side of the present invention;

In the figure: 1, skateboard; 2, wheel seat; 3, shaft; 4, sheave; 5, connecting screw; 6, connecting bolt; 7, positioning screw; 8, intubation; 9, semicircle on one side; 10, Semicircle on the other side; 11, the lower slotted plate; 12, the adjustment hole; 13, the side extension plate.

【detailed description】

The present invention can be explained in more detail by the following examples, and the purpose of disclosing the present invention is intended to protect all changes and improvements within the scope of the present invention, and the present invention is not limited to the following examples;

In conjunction with the cross arm described in accompanying drawing 1 or 2, replace the tension-resistant installation frame, comprise semicircle 9 on one side, semicircle 10 on the other side, slide plate 1, sheave 4 and lower grooved plate 11, semicircle 9 on one side, semicircle on the other side The side extension plate 13 at the butt joint end of the semicircle 10 forms a pole hoop through the connecting bolt 6, and intubation tubes 8 are respectively arranged on both sides of the outer edge of the hoop, and two adjustment tubes with internal threads are arranged on the outer walls of the two intubation tubes 8 up and down. Holes 12, positioning screws 7 pass through the adjustment holes 12 on the outer walls of the two intubation tubes 8, and are placed on the middle part of the two slide plates 1. The lower ends of the two slide plates 1 are respectively provided with a lower slotted plate 11, and the upper and lower sides of the two wheel bases 2 It is fixed on the upper outer side of the slide plate 1 by connecting screws 5 , and the shaft 3 of the sheave 4 passes through the wheel seat 2 .

Implement the cross arm of the present invention to replace the tension-resistant installation frame. When using, fix the side extension plate 13 of the semicircle 9 on one side and the semicircle 10 on the other side to the upper end of the utility pole, and then use the set screw 7 to adjust the position of the lower slotted plate 11. height, pass the two ropes through the two sheaves 4 respectively, and the personnel under the pole can pull the two tension-resistant cross-arms tied in the middle of the two tension-resistant cross-arms to the pole, and then the personnel on the pole can adjust the hoops of the two cross-arms , so that the two semicircular hoop cross arms are in the grooves of the lower slotted plate 11, the personnel on the pole can install the tension-resistant cross-arm; when the present invention takes off the tension-resistant cross-arm, two ropes are tied on The middle part of the tension-resistant cross-arm, and then the staff on the pole can disassemble the two tension-resistant cross-arms, which can effectively prevent the old two tension-resistant cross-arms from falling and hurting the people under the pole .

The unspecified parts of the present invention are prior art.
