Description

Technical Field

[0001] The invention belongs to the technical field of electric power, and in particular relates to an automatic installation device for an insulation piercing wire clamp. Background Art

[0002] The insulated piercing wire clamp is mainly composed of an upper and lower shell, a piercing blade, a sealing gasket, waterproof silicone grease, a bolt, and a nut. The upper and lower shells are connected by bolts and nuts. A lead hole and a main line hole are provided in the insulated piercing wire clamp. The piercing blade is provided on the inner wall of the lead hole and the main line hole. The piercing blades in the main line hole and the lead hole are connected by a conductor. The existing insulated piercing wire clamp is installed manually. During installation, the lead wire is first placed in the lead hole, the main line is placed in the main line hole, and then the nut is tightened. During the tightening process of the nut, the upper and lower shells are pressed. During this process, the piercing blade will pierce the insulation layer of the main line and the lead wire, and the piercing blade will contact the wires in the main line and the lead wire respectively, so that the main line and the lead wire are connected. The existing insulated piercing wire clamp is installed manually, and the operator is prone to electric shock accidents. It is dangerous during operation and directly threatens the personal safety of the operator. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the existing insulated piercing wire clamps are installed manually, the operators are prone to electric shock accidents, and the installation is relatively dangerous. An automatic installation device for insulated piercing wire clamps is provided, which can perform live operations and effectively ensure the personal safety of operators.

[0004] The objective of the present invention is achieved through the following technical scheme: an automatic installation device for an insulation piercing wire clamp, comprising a base, the base is provided with a wire clamp groove for placing the insulation piercing wire clamp, the base is provided with a guide rail, the guide rail is provided with a lead clamping mechanism, a nut tightening mechanism that moves with the lead clamping mechanism and is used to tighten the nut on the insulation piercing wire clamp, the base is provided with a first electric push rod for driving the lead clamping mechanism to move, the base is provided with a lead positioning block for positioning the lead and cooperating with the lead clamping mechanism to clamp the lead, and the base is rotatably connected to a wire clamp clamping arm that rotates with the lead clamping mechanism.

[0005] The present invention can be installed on a boom truck or other platforms for use. When the present invention is in use, the insulated puncture wire clamp is first placed in the wire clamp groove on the base, the lead wire is placed in the lead wire positioning hole, and then the first electric push rod pushes the lead wire clamping mechanism to move forward, and the lead wire clamping mechanism cooperates with the lead wire positioning block to clamp the lead wire. During the movement process, the lead wire clamping mechanism will drive the wire clamp pressing arm to rotate so as to fix and clamp the insulated puncture wire clamp, and on the other hand, it will simultaneously drive the nut tightening mechanism to move forward and dock with the nut on the insulated puncture wire clamp, and then the present invention is approached to the main line through the movement of the boom truck and the main line is stuck in the main line hole, and then the nut tightening mechanism is started to tighten the nut, and after tightening the nut, the first electric push rod moves in the opposite direction to reset the lead wire clamping mechanism, the nut tightening mechanism and the wire clamp pressing arm, and the insulated puncture wire clamp is separated from the present invention through the movement of the boom truck, thereby completing the installation of the wire clamp. The lead wire positioning block plays a positioning role on the lead wire, and can accurately load the lead wire into the lead wire hole. The present invention replaces manual operation with a mechanical method, and the operator does not need to be close to the main line, thereby ensuring the personal safety of the operator.

The lead pressing block is arranged on the first sliding seat and moves with the movement of the first sliding seat. The nut sleeve matches the nut on the insulation piercing wire clamp. When the first sliding seat moves, the pulling spring drives the second sliding seat to move, so that the nut sleeve is sleeved on the nut of the insulation piercing wire clamp. Under the action of the pulling spring, the nut sleeve can be tightly sleeved on the nut. After the motor is started, the nut sleeve can be driven to rotate, thereby tightening the nut.

[0007] Preferably, the nut tightening mechanism further comprises a transmission box, the output shaft of the motor is connected to the input shaft of the transmission box, and the nut sleeve is connected to the output shaft of the transmission box.

The function of the main line guide arm is to guide the main line, so that the main line can slide smoothly into the main line hole of the insulation piercing wire clamp. A guide surface is provided on the main line guide arm, and the main line slides into the main line hole along the guide surface. The main line guide arm can rotate under the drive of the second electric push rod. When the insulation piercing wire clamp is installed in the wire clamp groove, the main line guide arm rotates a certain angle so that the guide surface is located above the main line hole, so that the main line can slide smoothly into the main line hole under the action of the guide surface.

[0010] Preferably, the guide surface is an arc surface.
