An electric tensioning device and method for a tailstock of a digital distribution unit

Abstract

The invention discloses an electric tightening and loosening device for a tailstock of a digital wiring unit and a method. The device is mainly included and comprises a clamping mechanism and a rotating driving mechanism; the clamping mechanism comprises a chuck; multiple rubber wheel rotating shafts are evenly distributed on and surround the chuck; rubber wheels are mounted in positions, extending out of the chuck, of front ends of the rubber wheel rotating shafts; back ends of the rubber wheel rotating shafts are connected with shaft sleeves rotationally arranged on an end cover; the rotating driving mechanism comprises a motor; an output shaft of the motor is connected with a gear transmission mechanism; and an output shaft of the gear transmission mechanism is connected with the shaft sleeves. With the device, the rotating shafts and the rubber wheels are driven by the motor to rotate, and the tailstock of the digital wiring unit is tightened and dismounted rapidly under the effect of the clamping force of the chuck.

Description

technical field [0001] The invention relates to an electric tool, especially an electric tool for fast tightening and dismounting of a tailstock of a digital distribution unit of a digital distribution frame (cabinet) in a power communication machine room and an operator's communication machine room. Background technique [0002] The digital distribution frame (cabinet) is used for signal wiring and conversion between communication equipment, and the main wiring module is a digital wiring unit, such as figure 1 As shown, the digital wiring unit is mainly composed of panels, L9 five-piece set, conductive plate, grounding wire, cable fixing bracket and other components; L9 five-piece set is composed of Y-shaped head, double pass, and tailstock. Since the distance between the digital units of each system is relatively close, it is inconvenient to connect all the coaxial cables. After the coaxial cable and the tail pipe are welded or crimped, when the tailstock is tightened by h...

AI Technical Summary

Problems solved by technology

Since the distance between the digital units of each system is relatively close, it is inconvenient to connect all the coaxial cables. After the coaxial cable and the tail pipe are welded or crimped, when the tailstock is tightened by hand, due to the small space, it cannot be tightened, or When unscrewing the tailstock, the hand touches the Y-shaped head next to it, causing personal injury; some power communication rooms do not unscrew the tailstock, and it is easy to loosen the cable if it is accidentally touched later. The surface of the device is gold-plated, and it is easy to oxidize and contact with dust when exposed to air, which will affect the loss of internal and external conductors in the later stage

[0003] Although the construction personnel in the computer room know that it is difficult to install and disassemble the tailstock of the digital unit, and have developed some tools for the installation and removal of the tailstock of the digital unit, there are several problems in the existing tools: 1), because there are welding cables on the tailstock , the welding point is relatively weak, and it is easy to loosen when touched. The existing auxiliary tools do not consider the state of the tail pipe after welding the cable to rotate tightly, which will damage the coaxial cable; 2). Similarly, due to the existence of the coaxial cable , and the installation positions between the tailstocks are very close, ordinary auxiliary tools cannot rotate or loosen the tailstock of the digital distribution unit of the welded (or crimped) coaxial cable 360°, and can only rotate 180° at most ° (the cable is easy to be entangled on the tool, causing cable damage) and the coaxial cables are easy to knot, so the practicality is not high; 3), because the general electric elastic screwdriver is easy to screw the 2M head and tailstock ( There is no limit piece), which is not conducive to later maintenance; 4), due to the low efficiency of ordinary auxiliary tools, it takes a long time, which will cause the coaxial double-way connector in the tailstock to oxidize, affecting the loss of inner and outer conductors in the later stage

[0004] At present, the electric power is spreading in a large area to build a backbone communication network, and the amount of digital distribution frames (cabinets) in the communication room will also be large. At present, there is no special tool suitable for the quick loosening of the tailstock of the digital distribution unit, which has caused great harm to the construction personnel.
