Description

A kind of crane for power tower

technical field

The invention relates to a crane for power poles and towers, which belongs to the field of power transmission and transformation.

Background technique

At present, in the erection of high-voltage transmission towers, due to their high height, the raw materials need to be transported to the sky with the help of lifting equipment. At present, because there is no such equipment used in the construction of power towers, large cranes are usually used in construction. and other equipment, but large cranes need to occupy large site resources when used, so they cannot be used in areas with small construction sites such as mountains. The problem of high cost, and when large cranes and other equipment cannot be used, construction personnel often need to rely on manpower to lift and transport raw materials. The work intensity is huge and the efficiency is not high, which seriously affects the construction and maintenance of power poles and towers.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a crane for power poles and towers.

To achieve the above object, the present invention is achieved through the following technical solutions:

A crane for power poles and towers, the crane for power poles and towers is composed of a chassis plate, a support column, a lifting arm and a strengthening beam, the support column and the upper surface of the chassis plate are connected by bolts, and the support column consists of at least two The section cylinder is composed of and connected by bolts. The cylinder is a hollow cylindrical structure, and the two ends of the cylinder are provided with connecting flanges. The inner surface of the cylinder is evenly distributed with strengthening protrusions parallel to the axis of the cylinder. It is arc-shaped, and there are at least four hinged holes on the outer surface of the column. The reinforced beam is composed of at least two support arms, wherein one end of the support arm is hinged and the included angle is 15°-120°. The reinforced beam support arm The hinged end is hinged with the hinged hole of the column, and the other end of the support arm is connected with the power pole tower. The lifting arm is a hydraulic telescopic arm. The stranding wheel is connected, and the stranding wheel is provided with a backguy in addition, and the backguy naturally sags after passing the support wheel, and the front end of the backguy is additionally provided with a suspension hook, and the lifting arm is connected with the column through a steering mechanism in addition.

The steering mechanism is composed of a driving motor, a driving gear and a steering chainring, wherein the driving gear is connected with the driving motor and meshed with the steering chainring.

The cross section of the support arm is rectangular, triangular or oval.

The structure of the present invention is stable and light, and compared with the traditional lifting equipment, the site adaptability is stronger, and the on-site construction is more closely matched, which can greatly reduce the construction cost and the labor intensity of the construction personnel, and improve the construction quality and efficiency.

Detailed ways

As shown in Figures 1 and 2, a crane for power poles and towers, the crane for power poles and towers is composed of a chassis plate 1, a support column, a lifting arm 2 and a strengthening beam, and the support column and the upper surface of the chassis plate 1 Connected by bolts, the support column is composed of at least two columns 3 and connected by bolts, the columns 3 are hollow cylindrical structures, wherein the two ends of the columns 3 are provided with connecting flanges 4, and the inner surfaces of the columns 3 are uniform. The reinforced protrusions 5 parallel to the axis of the cylinder are arranged, the section of the reinforced protrusions 5 is arc-shaped, and the outer surface of the cylinder 3 is partially provided with four hinged holes 6, and the reinforced beam is composed of at least two support arms 7 One end of the support arm 7 is hinged and the included angle is 15°-120°. The hinged end of the reinforced beam support arm 7 is hinged with the hinge hole 6 of the column body 3. The other end of the support arm 7 is connected with the power tower 8. The lifting arm 2 is a hydraulic telescopic arm, and the front end of the upper surface of the lifting arm 2 is provided with a backguy support wheel 9, and the rear end is provided with a stranding wheel 10 and a driving device 11, and the driving device 11 is connected with the stranding wheel 10, and the stranding wheel 10 is provided with a backguy 12 in addition, and a backguy 12 hangs down naturally after passing through the supporting wheel 9, and the front end of the backguy 12 is additionally provided with a suspension hook 13, and the lifting arm 2 is connected with the column body 3 through a steering mechanism in addition, and the steering mechanism is composed of a driving motor 14, a driving gear 15 and a steering chainring 16, Wherein the driving gear 15 is connected with the driving motor 14 and meshes with the steering chainring 16 .

When in use, the chassis plate is pre-embedded and installed at the center or side of the foundation of the transmission tower, and then one end of the column constituting the support column is fixed on the chassis plate by bolts, and the other end is connected to the lifting arm, and the column body is connected with the lifting arm. The height of the transmission tower increases step by step, and the supporting column body can be connected to the completed position of the transmission tower through the reinforced beam. As the height of the transmission tower increases, the ground materials can be lifted to the construction position through the lifting arm.
