Description

Technical Field

[0001] The present invention relates to the technical field of power cable erection, and particularly to a crimping device for field power cable erection. Background Art

[0002] When building a power system, it is often necessary to erect a large number of cables in the wild. The coiled cables have no joints, and when installing cables in the wild, it is necessary to manually install cable joints at both ends of the cables. Currently, when installing a cable joint, a person first uses a tool to cut off the outer skin of the cable. This process may cut a person's hand and is somewhat dangerous. After the outer skin is cut off, it is necessary for a person to pull off the outer skin to expose the core. Since the outer skin tightly wraps around the core, it is very laborious to manually tear it off. Finally, it is necessary for a person to put the cable joint on the core and then use other tools to tightly crimp the joint onto the core, which is rather troublesome. Therefore, in view of the above current situation, there is an urgent need to develop a crimping device for field power cable erection that has various functions, can cut off the outer skin of the cable and tightly press and fix the cable joint to the core of the cable, is convenient to use, saves manpower, and has higher safety, so as to overcome the deficiencies in current practical applications and meet the current requirements. Summary of the Invention

[0003] The purpose of the present invention is to provide a crimping device for field power cable erection to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A crimping device for field power cable erection includes an outer frame, a support seat, a pressing mechanism, a circumferential cutting mechanism, a pushing and pulling mechanism, a crimping mechanism, a lifting handle, and a mobile power source. The support seat is fixedly installed inside the outer frame. A positioning groove is provided on the support seat. The pressing mechanism is fixedly installed on the support seat. The circumferential cutting mechanism is installed on the front side of the support seat. The pushing and pulling mechanism is installed inside the outer frame on the front side of the support seat. The crimping mechanism is arranged on the pushing and pulling mechanism. When in use, first pass the cable through the positioning groove, press the cable onto the support seat through the pressing mechanism, then clamp the front end of the cable by the crimping mechanism. Then, cut off the wrapping layer outside the cable through the circumferential cutting mechanism. Then, drive the crimping mechanism to move forward through the pushing and pulling mechanism, and pull off the cut wrapping layer on the cable forward through the crimping mechanism, so that the core inside the cable is exposed. Then, put the cable joint on the core of the cable, drive the crimping mechanism to return by the pushing and pulling mechanism, and then squeeze the cable joint by the crimping mechanism so that the cable joint tightly fits onto the core of the cable.

[0005] Preferably, the pressing mechanism includes: a heightening frame, a first electric telescopic rod, and a pressing ring. The heightening frame is fixed to the support base.

During use, a person turns the rotary handle by hand. The rotation of the rotary handle drives the threaded sleeve to rotate. The rotation of the threaded sleeve drives the threaded rod to move downward. The threaded rod drives the lifting plate and the cutting blade to move downward, so that the cutting blade cuts into the outer skin of the cable. Then, the output shaft of the first motor drives the small gear to rotate. The rotation of the small gear drives the large gear to rotate. The rotation of the large gear drives the transfer plate to rotate. The rotation of the transfer plate drives the cutting mechanism to rotate, so that the cutting blade rotates around the cable for one circle, thereby cutting off the outer skin of the cable.

[0008] Preferably, the pushing and pulling mechanism includes: a second electric telescopic rod, a connecting block, a support plate, a slider, and a linear slide rail. Two second electric telescopic rods are fixedly installed within the outer frame. The telescopic end of each second electric telescopic rod is fixedly connected to a connecting block.

The two crimping blocks are arranged oppositely. A second limiting guide rod that is inserted into the support plate is fixed to the lower sides of the first threaded block and the second threaded block. The helix directions of the first external thread and the second external thread are opposite. When in use, the second motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the first threaded block and the second threaded block to move towards each other. The first threaded block and the second threaded block drive the two crimping blocks to move towards each other.

[0010] Preferably, the second limiting guide rod is slidably connected to the support plate, and a limiting sliding groove for the movement of the second limiting guide rod is provided on the support plate.

[0013] The beneficial effects of the present invention are as follows: When using the crimping device for field power cable erection, the cable is passed through the positioning groove, and then the pressing ring is driven down by the first electric telescopic rod. The cable is pressed into the positioning groove by the pressing ring. Then, the second motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the first threaded block and the second threaded block to move towards each other. The first threaded block and the second threaded block drive the two crimping blocks to move towards each other, so that the two crimping blocks clamp the outer skin of the cable. Then, a person rotates the rotary handle by hand. The rotation of the rotary handle drives the threaded sleeve to rotate. The rotation of the threaded sleeve drives the threaded rod to move downwards. The threaded rod drives the lifting plate and the cutting blade to move downwards, so that the cutting blade cuts into the outer skin of the cable. Then, the output shaft of the first motor drives the small gear to rotate. The rotation of the small gear drives the large gear to rotate. The rotation of the large gear drives the transfer plate to rotate. The rotation of the transfer plate drives the slitting mechanism to rotate, so that the cutting blade rotates around the cable for one circle, thereby cutting off the outer skin of the cable. Then, the second electric telescopic rod drives the connecting block and the support plate to move forward. The support plate drives the crimping mechanism to move forward, so that the crimping mechanism pulls out the cut outer skin on the cable. Then, the crimping mechanism loosens the cable, so that the core of the cable is exposed. Then, the cable joint is sleeved on the core of the cable. The pushing and pulling mechanism drives the crimping mechanism to return to its position, and then the two crimping blocks approach each other, so that the two crimping blocks tightly fit the cable joint to the core of the cable. In summary, the present invention has various functions. It can not only cut off the outer skin of the cable but also tightly press and fix the cable joint to the core of the cable. It is convenient to use, saves manpower, and has higher safety. BRIEF DESCRIPTION OF THE DRAWINGS
