[0002] With the continuous development of cities in various regions, the factors affecting the traffic capacity of urban roads are gradually increasing. In order to improve the traffic capacity of roads, various cities and regions are constantly building high-speed railways, highways, etc., and overhead transmission lines are an important part of the current power grid. Correspondingly, the number of crossings between overhead transmission lines and high-speed railways, highways and other roads has also increased. In order to make the overhead wires meet the safety distance for important crossings, an optimized design of the tower crossarm is proposed.

[0006] The outer side of the motor is sleeved with a rain cover, and the inner side wall of the rain cover is provided with a power supply for supplying power to the motor;

[0007] An anti-mistouch ring is arranged on the outer side of the motor start button, and a protrusion is arranged on the forward rotation opening button of the motor start button.

[0008] Preferably, a right-angle surface matching the side surface of the tower is provided on the side of the second connecting seat close to the tower.

[0009] Preferably, a rubber gasket is laid on the right-angle surface.

[0010] Preferably, the movable block is a metal block with a threaded hole in the middle and a slot on the side, and a limiting rod is welded on the side of the second connecting seat, and the other end of the limiting rod passes through the movable block.

[0011] The technical effects and advantages of the present invention are as follows: the iron tower temporarily fixes the cross arm with a bypass cable, and the forward and reverse rotation of the motor is used to realize the rapid loading and unloading of the cross arm, which saves time and effort, reduces the workload of operators, and eliminates the need for operators to carry the cross arm and turn the screw at the same time, making it more practical.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The present invention provides Figure 1-2The shown embodiment is a temporary fixed cross arm for bypass cables of an iron tower, comprising a cross bar 1 and a first connecting seat 2 fixedly mounted on the cross bar 1, one end of the cross bar 1 is sleeved with a second connecting seat 3, the inner side of the second connecting seat 3 is provided with a cavity 4, a motor 5 is fixedly mounted on the lower end of the second connecting seat 3, the output shaft of the motor 5 extends into the cavity 4, and a first gear disc 6 is fixedly mounted on the output shaft of the motor 5, a screw rod 7 is rotatably mounted on the side of the second connecting seat 3, a second gear disc 8 is welded to one end of the screw rod 7 extending into the cavity 4, the second gear disc 8 is transmission-connected with the first gear disc 6, the screw rod 7 passes through a threaded hole through which a movable block 10 is opened, and the screw rod 7 is threadedly connected to the movable block 10, and two motor start buttons 11 are provided at the lower end of the second connecting seat 3, which respectively control the forward and reverse rotation of the motor 5. After placing the cross arm in a suitable position, press the motor start button 11 to start the motor 5, so that the movable block 10 moves along the screw rod 7, so that the movable block 10 finally clamps the side of the tower connecting frame, release the motor start button 11, and the motor 5 is turned off, thereby completing the fixation. It is convenient and quick, eliminating the need for the operator to carry the cross arm and turn the screw rod 7 at the same time, reducing the operator's workload and making it more practical.

[0017] The outer side of the motor 5 is sleeved with a rain cover 12, and the inner side wall of the rain cover 12 is provided with a power supply 13 for supplying power to the motor 5 to prevent rainwater from soaking into the inside of the motor 5 and causing damage to the motor 5.

[0018] The outer side of the motor start button 11 is provided with an anti-accidental touch ring 14, and the forward start button of the motor start button 11 is provided with a protrusion 15. By providing the anti-accidental touch ring 14 slightly lower than the motor start button 11, the operator is prevented from accidentally pressing the motor start button 11 and causing the motor 5 to start unexpectedly. The protrusion 15 can facilitate the operator to accurately find the button corresponding to the forward or reverse rotation of the motor start button 11, thereby starting the motor 5 to rotate forward and reverse, and realizing the installation or disassembly operation of the crossarm.

[0019] The second connecting seat 3 is provided with a right-angle surface 16 matching the side of the tower on one side close to the tower. After the movable block 10 presses both sides of the connecting frame of the tower, the right-angle surface 16 presses against the front of the connecting frame of the tower, fitting tightly to ensure the stability of the installation.

[0020] A rubber gasket 17 is laid on the right-angle surface 16 to provide a buffer to prevent the second connecting seat 3 from pressing the iron tower connection too tightly and causing damage.

[0021] The movable block 10 is a metal block with a threaded hole in the middle and a slot 19 on the side, and a limiting rod 18 is welded to the side of the second connecting seat 3. The other end of the limiting rod 18 passes through the movable block 10. The limiting rod 18 limits the movable block 10 to prevent the movable block 10 from rotating, ensuring that the movable block 10 slides stably along the screw rod 7 and hangs on the side of the tower connecting frame through the side groove to complete the tightening.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
