4results about How to "Increase maintenance space" patented technology

The application discloses a rail polishing unit and a rail polishing trolley, and the rail polishing unit comprises a suspension assembly, a unit frame assembly, a motor mounting platform, a motor guide assembly, a polishing motor, a polishing grinding wheel, a lifting driving mechanism and a deflection driving mechanism. The suspension assembly is connected with a trolley frame, and the unit frame assembly is slidably connected with the suspension assembly. The motor mounting platform is hinged with the lower part of the unit frame assembly, and the motor guide assembly is connected with the motor mounting platform. The polishing motor is slidably connected with the motor guide assembly, and the polishing grinding wheel is connected with the output shaft of the polishing motor. The two ends of the lifting driving mechanism are respectively hinged with the polishing motor and the motor mounting platform. The two ends of the deflection driving mechanism are respectively hinged with the trolley frame and the motor mounting platform. The application can solve the technical problems of the existing rail polishing unit, such as large space occupation, large lifting resistance, low polishing efficiency and poor maintainability.

The utility model discloses a kind of operation systems for steel metallurgical industry mixing iron furnace area, comprising: a high corridor;A sampling platform is obtained by being outwardly extended and being arranged from high corridor, and is located the top of track;A lifting baffle, it is located at the front end of tank car direction of one side edge of sampling platform and is set;A sampling groove, it is strip long groove on sampling platform along the extension direction of track, the edge of sampling groove is provided with scale and track along its extension direction;A slider, it is the block structure with through hole in center, it is arranged across sampling groove, for sliding in two tracks correspondingly;Lifting baffle is used to give the guidance of tank car parking position for lowering;Slider is used to move to the best area of sampling according to scale;Sampling rod, vertically insert into the ladle of tank car through the center through hole of slider to sample down.It solves the problem of poor safety of existing mixing iron furnace area work, inconvenient sampling.

The application provides a mechanical hand clamp changing tool, which comprises a bottom plate, a vertical plate fixedly connected with the bottom plate, a clamp locking device arranged on a first side of the vertical plate and fixedly connected with the bottom plate, a clamp toe changing device arranged on a second side of the vertical plate and fixedly connected with the bottom plate, a clamp changing device fixedly connected on the surface of the second side of the vertical plate, a mechanical hand sleeve fixing seat dismounting device and a clamp positioning device. The scheme has the advantages of simple structure, simple working principle, increased maintenance space for personnel in the maintenance process, reduced radiation dose of workers in the maintenance process, greatly improved work efficiency, realized continuous and stable operation of the mechanical hand in the radioactive environment and ensured stable operation of the main process system.

The present application relates to the technical fields of heating furnace, and discloses a crude oil conveying skid-mounted pipeline heating furnace, which comprises a protective shell, the lower surface of the protective shell is fixedly connected with a support frame, the inner wall of the support frame is fixedly connected with a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly provided with a moving frame, the outer wall of the moving frame is slidably connected with the inner wall of the protective shell, the upper surface of the moving frame is fixedly connected with a fixing frame, the inner wall of the fixing frame is slidably connected with a vibrating plate, the upper surface of the vibrating plate is fixedly connected with a support, and the inner wall of the support is fixedly connected with a skid-mounted pipeline heating furnace body. By opening the hydraulic cylinder to drive the moving frame to move downward, the inclined plate is extruded with the inner wall of the protective shell, the sliding block is gradually slid inward in the moving frame, the clamping block is centered and moved, the fixing and clamping of the heating furnace are completed, the stability of operation is ensured, and when the moving frame moves upward, the heating furnace is moved to the upper surface of the protective shell, the clamping block is separated from the outer wall of the heating furnace, and the effect of expanding the maintenance space is achieved.
