Electromechanical pipeline pre-embedding device

ActiveCN224289197UReduce the inconvenience of fixing to the casingImprove plugging efficiencyPipe laying and repairElectrical apparatusEmbedded technologyLine tubing
This application relates to a pre-embedded electromechanical pipeline device, belonging to the field of electromechanical pipeline pre-embedded technology. It includes a sleeve with caps at both ends. The caps have internal fixing components for securing them to the sleeve. Each fixing component includes two sets of snap-fit ​​blocks, a support plate fixedly installed on the outer surface of each snap-fit ​​block for support, a T-shaped slider fixedly installed at opposite ends of the two support plates, and a moving structure fixedly installed on opposite sides of the two snap-fit ​​blocks for pushing them to move. This pre-embedded electromechanical pipeline device, by incorporating the fixing components, ensures that when the caps are removed from the sleeve, the snap-fit ​​blocks, support plates, T-shaped sliders, screws, operating blocks, pull plates, push-pull rods, support blocks, crossbars, and connecting blocks are all fixedly installed inside the caps. This effectively reduces the difficulty of securing the caps to the sleeve due to missing parts and improves the sealing efficiency of the sleeve.

A device and method for preparing rubber linings for pipes

This invention discloses a device for preparing rubber linings for pipes, comprising a base plate, a placement frame fixedly connected to the front of the base plate, and a pipe movably sleeved on the top of the placement frame. The invention utilizes an inner annular groove and a flow channel within a support plate, along with a mounting ring fixedly fitted to the outer surface of a spraying rod and a hole on the mounting ring. Hot-melt rubber is introduced into the internal channel of the spraying rod, and with the aid of annularly distributed outlet pipes, the hot-melt rubber is sprayed into the space between the pipe and the spraying rod, forming a lining layer. During the gradual cooling and curing process, a motor continuously rotates the spraying rod to prevent the cured lining from adhering to it, ensuring easy removal of the spraying rod after curing. This maintains the stability of the rubber lining and prevents tearing during separation if the lining is adhered, ensuring stable molding and good performance of the rubber lining.
