[0023] The beneficial effects of the present invention are as follows:

[0024] 1) The insulating sheath closing device of the present invention consists of an upper shell and a lower shell, which are used to place and close the insulating sheath of the parallel groove wire clamp. The upper shell and the lower shell are provided with grooves adapted to the insulating sheath structure, and the insulating sheath of the parallel groove wire clamp is placed in the grooves; the upper shell and the lower shell are hingedly connected to form a structure that can be opened and closed, and the insulating sheath has an automatic snap-fitting function.

Regardless of the angle of the rod body held by the operator and the conductor, the insulating sheath closing device is always parallel to the ground, and the parallel groove wire clamp can also be used as a reference point to adjust the insulating sheath closing device to any angle; the mechanical structure is simple and the transmission is reliable, which can effectively solve the problem of live installation of the insulating sheath of the parallel groove wire clamp under special terrain conditions.

[0026] 3) The present invention is powered by a DC motor, which can realize forward and reverse rotation through a remote control switch.

DETAILED DESCRIPTION

[0037] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0039] As described in the background, the left and right clamping plates of conventional live insulation sleeve installation tools are not suitable for installing the insulation sleeves of parallel-groove cable clamps. Consequently, they cannot transport the insulation sleeves over long distances and are not adaptive to the installation angle of the insulation sleeves. To address these technical issues, the present invention proposes an insulating rod for installing the insulation sleeves of parallel-groove cable clamps.

[0040] Example 1

[0041] In a typical embodiment of the present invention, Figure 1-2As shown, an insulating rod for installing an insulating sheath includes a rod body 6, a balancer assembly disposed at the end of the rod body 6, and an insulating sheath closing device mounted on the balancer assembly. The rod body 6 is made of insulating material and provides insulation. The insulating sheath closing device includes an upper shell 1 and a lower shell 2. The upper shell 1 is provided with an upper groove 1-2 adapted to the insulating sheath structure, and the lower shell 2 is also provided with a lower groove 2-2 adapted to the insulating sheath structure. The insulating sheath of the parallel groove clamp can be placed in the groove. The upper shell 1 is provided with a first hinged ear 1-4; the lower shell 2 is provided with two second hinged ears 2-5, which are adapted to the first hinged ears 1-4. The upper shell 1 and the lower shell 2 are hingedly connected to form an openable and closable structure. The opening and closing structure closes the insulating sheath, and the insulating sheath has an automatic snap-fit ​​function. When the upper shell 1 and the lower shell 2 are closed, the insulating sheath automatically snaps in place.

[0042] like Figure 3-4 As shown, the parallel groove wire clamp is a connecting hardware between the main line and the lead wire. It is necessary to consider the structure of the main line and the lead wire passing through the insulating sheath. Therefore, four semicircular first wire grooves 1-3 are provided on the upper shell 1, and four semicircular second wire grooves 2-3 are provided on the lower shell 2. The first wire grooves 1-3 and the second wire grooves 2-3 are arranged relative to each other to form a circular hole groove for the wire to pass through.

[0043] The balancer assembly includes a dual-annular balancer 4 and a drive control assembly 5 for an insulating sheath closing device. The dual-annular balancer 4 is used to ensure that the cylindrical housing of the drive control assembly always remains in an axially vertical state. The drive control assembly 5 includes a power supply, a micro-motor drive mechanism, and a control unit. The micro-motor drive mechanism is connected to the upper housing 1 via a push rod 3 and is used to drive the opening and closing of the upper housing 1. The lower end of the push rod 3 is connected to the micro-motor drive mechanism. The micro-motor drive mechanism is composed of a worm gear connected to the motor main shaft, the worm gear is connected to the lower end of the push rod 3, and the upper end of the push rod 3 is hinged to the drive hinge lug 1-5 provided on the upper housing 1. When the motor drives the worm gear to rotate, it will drive the worm gear to reciprocate, thereby driving the upper housing 1 to rotate around the axis of the first hinge lug 1-4 through the push rod 3, thereby realizing the opening and closing of the upper housing 1 and the lower housing 2.

[0044] The control unit is used to control the rotation and stop of the motor. The control unit consists of a wireless signal receiver and a control module, and is used to receive signals from the remote control switch 7. The control unit can choose existing technology and will not be repeated here.

[0045] like Figure 6As shown, the drive control assembly 5 is cylindrical, and a through hole 5-3 is provided on the upper bottom surface of the cylinder for passing the push rod 3 so that the push rod 3 can reciprocate under the action of the micro-motor drive mechanism; two first support shafts 5-2 are radially arranged on the assembly shell 5-1 of the drive control assembly 5.

[0046] The double ring balancer 4 includes an inner ring 4-3 and an outer ring 4-2. The outer side surface of the inner ring 4-3 is provided with two second support shafts and two first through holes 4-1 penetrating the inner side surface along the axial direction. The outer side surface of the outer ring 4-2 is provided with two second through holes penetrating the inner side surface. Figure 5 As shown, the two first through-holes 4-1 provided on the inner ring 4-3 are used to mount the first support shaft 5-2, and the inner diameter of the inner ring 4-3 is larger than the diameter of the drive control assembly 5. The two second through-holes provided on the outer ring 4-2 are used to mount the second support shaft, and the radial directions of the first through-holes 4-1 and the second support shaft are perpendicular to each other. The dual-ring balancer 4 functions similarly to a gyroscope structure. The first support shaft 5-2 can rotate about its own axis within the first through-hole 4-1, and the second support shaft can rotate about its own axis within the second through-hole. The drive control assembly 5 is light on top and heavy on the bottom. Under the action of gravity, regardless of the angle at which the rod body 6 is tilted, the dual-ring balancer 4 can ensure that the cylindrical axis of the drive control assembly 5 is perpendicular to the horizontal plane. In its normal state, the parallel groove wire clamp is horizontal, and the direction of the lead through-holes in the upper shell 1 and lower shell 2 above the drive control assembly 5 is consistent with the direction of the parallel groove wire clamp. When the parallel groove clamp has a certain inclination angle, the angle of the insulating sheath closing device can be fine-tuned by the rod body 6 with the parallel groove clamp as a reference point to adapt to the direction of the parallel groove clamp, thereby ensuring that the insulating sheath is installed in place.

[0047] like Figure 7 As shown, the rod body 6 is made of insulating material, and the rod body 6 can be extended by connection so as to adjust the length according to different working scenarios. The end of the rod body 6 is fixedly connected to the side of the outer ring 4-2, and can be fixedly connected by screws or the like; a handle is provided at the lower end of the rod body 6, and a remote control switch 7 is provided above the handle, which has a motor standby button, a motor forward and reverse buttons for controller standby and operation and motor forward and reverse operation. The remote control switch 7 controls the control unit through wireless signals, and the control unit drives and controls the micro motor drive mechanism.

[0048] Example 2

[0049] How to use the insulating rod for installing the insulating sheath:

[0050] S1: placing the insulating sheath of the parallel groove clamp in the insulating sheath closing device, which is used to transport the insulating sheath from the ground to the parallel groove clamp in the air. The insulating sheath of the parallel groove clamp is in an open state and placed in the grooves in the upper shell and the lower shell to prevent the insulating sheath from falling off during long-distance transportation;

[0051] S2: After the operator reaches the working position, he / she adjusts the rod to an appropriate length so that the insulating sheath closing device can reach the parallel groove clamp and align the insulating sheath with the parallel groove clamp. If the insulating sheath and the parallel groove clamp cannot be aligned, the lower housing and the parallel groove clamp are used as fulcrums, and the double ring balancer can be used to rotate to fine-tune the angle of the insulating sheath closing device so that it is aligned with the parallel groove clamp.

[0052] S3: The operator holds the handle and controls the motor through the remote control switch to drive the push rod 3 to close the upper shell, and then the insulating sheath of the groove clamp is automatically engaged;

[0053] S4: After the insulating sheath of the parallel groove wire clamp is firmly engaged, the motor is controlled to move in the reverse direction through the remote control switch, the insulating sheath closing device opens, and then the operator holds the rod and moves it downward to separate from the insulating sheath.

[0054] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
