4results about How to "Resolve rebound" patented technology

The utility model belongs to mechanical safety and protection device field especially, it is a kind of buffer mechanism of elevator, it includes buffer base, the bottom of buffer base is equipped with four connecting chambers, the inside of four connecting chambers is equipped with four spherical grooves;The bottom of buffer base is equipped with four permanent magnet dampers, the top of four permanent magnet dampers is all fixedly installed with connector, four connectors are respectively matched with corresponding connecting chamber.This utility model can improve the energy absorption efficiency high and wide range of adaptation, cope with high speed or heavy load impact, make overall structure can adapt the multiple working conditions from low speed light load to high speed heavy load, and the oil in hydraulic sleeve can effectively inhibit the elastic rebound of disc spring and alloy spring, avoid the rebound problem of traditional single spring structure, greatly improve the buffering effect of equipment.

The utility model discloses a scouring pad leveling device, which relates to the technical field of scouring pad leveling, and comprises an operating table and a mounting plate, the upper side of the operating table is fixedly connected with a vertical plate, two groups of symmetrically arranged positioning mechanisms are mounted outside the vertical plate, the outside of the operating table is fixedly connected with a mounting seat, and the mounting seat is fixedly connected with a base. A heating mechanism is mounted on one side of the mounting seat, two groups of symmetrically arranged sliding plates are slidably connected to the upper side of the operating table in a limiting manner, a leveling strip is fixedly connected to the bottom of the mounting plate, the tail end of the leveling strip is sharpened, and a pressing mechanism is mounted between the mounting plate and the sliding plates. According to the device, through the dual effects of heating power and mechanical force, the scouring pad fiber reset resistance is remarkably reduced, the efficient and uniform leveling effect is achieved, and meanwhile the device can meet the machining requirements of scouring pads of different sizes.

This invention discloses a tunnel shotcrete rebound recovery device, which includes a transport vehicle equipped with a collection device for collecting rebounded concrete, a mixing device for thoroughly mixing the collected concrete, and a compensation device for compensating the mixed concrete with slurry. The collection device includes a collection funnel with two aggregate plates inclined to both sides, and a storage bin at the bottom of the collection funnel. The mixing device includes a mixing drum driven by a drive motor, with an inlet and an outlet at both ends of the mixing drum. A conveying mechanism is provided between the storage bin and the inlet to transport a fixed amount of concrete from the storage bin to the mixing drum. A discharge funnel is located below the outlet, and a pump is located below the discharge funnel, with a conveying pipe at the outlet end of the pump. This solution enables automated recovery and utilization of rebounded concrete, avoiding resource waste.
