The application belongs to the technical field of communication construction, and particularly relates to a pay-off device for communication construction. In view of the problem that the existing communication wiring equipment cannot stably fix various specifications of cable rollers, the following scheme is proposed, which comprises a fixing base, a fixing plate vertically arranged and welded and fixed at the top of the fixing base, a guide wire disc fixing frame slidably connected to the inner wall of one side of the fixing base, the fixing base being fixed at the top position through bolts, and a driving machine box fixed at the middle position of one side of the fixing plate through bolts. The electric push rod can push out the supporting plate and contact the inner wall of the wire roller disc, so that the wire roller disc can be stably fixed.

This utility model discloses a grinding fluid dilution testing device, comprising: a main water inlet pipe, a first valve and a first check valve, two water inlet components, each water inlet component including a water inlet pipe, a first three-way valve and a first flow meter; two sample injection components, each sample injection component including a first sample injection pipe, a peristaltic pump and a second flow meter; the water inlet pipe and the first sample injection pipe are both connected to a delivery pipe, the delivery pipe being equipped with a third three-way valve, a third flow meter and at least one detector; an empty pipe is connected to the delivery pipe; the second sample injection pipe is equipped with a fourth three-way valve, a second valve, and at least one second check valve, the second sample injection pipe being connected to the output end of the delivery pipe, and the output end of the second sample injection pipe being connected to the main water inlet pipe. This utility model enables the mixing and dilution of grinding fluid and pure water through two pipelines, with backup measures, improving testing efficiency, and allowing switching to the corresponding pipeline according to different needs to meet different testing requirements.

This invention discloses a manufacturing and forming method for steel wire mesh reinforced tubes, relating to the technical field of steel wire mesh reinforced tubes. The method includes the following steps: S1, fixing the steel wire unwinding coil onto the cross-shaped positioning rod using a cross-shaped positioning rod, and using the magnetic force of a stopping electromagnetic ring to attract and fix the position of the metal limiting block and the cross-shaped positioning rod. The steel wire is then passed through the steel wire docking box, tensioning guide wheel, burr removal channel, and steel wire welding wheel located at the top of the welding support shaft seat. This invention has a scientifically sound and reasonable structure, and is safe and convenient to use. Through the cooperation of a detection camera, electrically controlled wire clamping pliers, a sleeve electric push rod, and hydraulic crimping pliers, the detection camera observes the steel wire passing through the steel wire docking box, thereby clamping and fixing the end of the old steel wire, limiting it below the hydraulic crimping pliers to prevent the steel wire from running out. Simultaneously, it facilitates moving the hydraulic crimping pliers and sleeve to the top of the end of the old steel wire.
