Detailed Description
The present invention will be described in detail below with reference to the drawings and detailed embodiments for better understanding of the technical aspects of the present invention by those skilled in the art.
As shown in fig. 1 to 8, the present invention discloses a device for hooking a rope to an overhead line, which comprises a bracket 10, a telescopic mechanism 20, a swing arm 30, and a clamping mechanism 40. The bracket 10 is detachably arranged on the cross arm 100 of the electric tower, and the cross arm 100 of the electric tower is vertical to the trend of the overhead line 200 (can be perpendicular to different surfaces). The telescopic mechanism 20 is transversely arranged on the support 10 and can rotate on a plane perpendicular to the extending direction of the telescopic mechanism 20, and the extending direction of the telescopic mechanism 20 is parallel to the running direction of the overhead line 200. The swing arm 30 is connected to the distal end (end remote from the bracket 10) of the telescopic mechanism 20 to swing by rotation of the telescopic mechanism 20. Attached to the free end of the rocker arm 30 is a clamping mechanism 40, the clamping mechanism 40 having a clamped condition to hold the cord 400 thereon and an open condition to release the cord 400. When the telescopic mechanism 20 is telescopic and the swing arm 30 swings to drive the clamping mechanism 40 to cross the overhead wire 200 from above the overhead wire 200, the clamping mechanism 40 is switched from the clamping state to the open state, and the rope 400 is released to hang the rope 400 on the overhead wire 200.
The following describes a method of using the device described above:
as shown in fig. 7, firstly, the whole device is installed on a cross arm 100 of an electric tower by means of a bracket 10, and at this time, a telescopic mechanism 20 is parallel to an overhead line 200 and is at a distance from the overhead line 200; switching the clamping mechanism 40 to an open state, disposing the rope 400 in the clamping mechanism 40 and switching the clamping mechanism 40 to a closed state again, at which time the rope 400 is held by the clamping mechanism 40; then, as shown in fig. 8, the telescopic mechanism 20 is extended to a length that can avoid the stopper after the swing arm 30 swings (the present application will be described only by taking the case of avoiding the damper 300); then, as shown in fig. 8, when the telescopic mechanism 20 is rotated to rotate the swing arm 30 and the rotation angle of the swing arm 30 is such that the rope 400 held by the holding mechanism 40 straddles the overhead wire 200, the holding mechanism 40 is controlled to switch to the open state, and at this time, the rope 400 falls to be hung on the overhead wire 200.
The present invention uses the telescopic function of the telescopic mechanism 20 and the swing function of the swing arm 30 to avoid the obstacle and to cross the rope 400 over the overhead line 200, and the rope 400 is hung on the overhead line 200 by opening the clamping mechanism 40, thereby avoiding a series of problems mentioned in the background art caused by the adoption of a worker to throw the rope 400.
In a preferred embodiment of the present invention, as shown in fig. 3 and in combination with fig. 2, the stand 10 includes a card holder 11 and a column 12 disposed on the card holder 11; telescoping mechanism 20 is connected to upright 12; wherein: the bottom of the clamping seat 11 is provided with a clamping groove 111 penetrating along the extending direction of the cross arm 100; two opposite side walls of the clamping groove 111 are provided with a storage groove 114, a stop block 112 is arranged in the storage groove 114, a spring 113 is connected between the stop block 112 and the groove bottom of the storage groove 114, the head of the stop block 112 extends out of the groove wall, a guide surface 1121 is formed at the lower part of the stop block 112, and the cross arm 100 is forced to retract and extend out by contacting with the guide surface 1121 so that the cross arm 100 is clamped in the clamping groove 111 above the stop block 112.
The advantages of the above embodiment are:
the whole device can be firmly clamped on the cross arm 100 by utilizing the extension and contraction of the stop block 112, and the fixing process is simple and the operation is convenient.
In a preferred embodiment of the present invention, as shown in FIG. 2, a torsion mechanism 50 is provided between the telescopic mechanism 20 and the bracket 10; the torsion mechanism 50 includes: stator sleeve 51, rotor shaft 52, and torsion springs.

In this embodiment, the telescopic mechanism 20 drives the swing arm 30 to swing by applying a torsion force to the handle 53, so that the rope 400 is convenient to transport to the upper side of the overhead line 200. In addition, by reasonably setting the stopper structure, the rocker arm 30 automatically returns under the action of the torsion spring after the rope 400 is released. For example, the rocker arm 30 may be automatically returned to the vertical state by reasonably providing the stopper structure, but naturally, the rocker arm 30 may be automatically returned to the vertical state by providing the torsion state of the torsion spring, for example, when the rocker arm 30 is in the vertical state, the installation state of the torsion spring is in a free state without elastic potential energy, that is, without torque, and further, the swing may be naturally returned.
It should be noted that: in most cases, the rocker arm 30 is normally not limited by a stop structure, so as to prevent the rocker arm 30 from being unable to avoid obstacles or interfering with other objects (including operators) due to limited swinging in the opposite direction.
In a preferred embodiment of the present invention, as shown in fig. 5, the clamping mechanism 40 is mounted on the rotating shaft 60, and the rotating shaft 60 is mounted on the free end of the rocker arm 30 via the bearing 80, so that the clamping mechanism 40 is always in an open orientation when the rocker arm 30 swings. In this embodiment, the bearing 80 prevents the rotation shaft 60 from being damped, so that the clamping mechanism 40 is always in an upright state with an opening facing, and thus the rope 400 is conveniently released.

The moving lever 22 expands and contracts to change the length of the expansion mechanism 20 by the driving of the first motor 241. A stop switch is provided on the rear end of the outer tube 21, and controls the first motor 241 to stop operating when the moving lever 22 is completely retracted.
