The utility model relates to the technical field of electric power cross arm machining, and discloses a cutting device for electric power cross arm machining, which comprises a cutting table, a cutting limiting seat is fixedly mounted at the top of the cutting table, a cutting limiting groove is formed in the cutting limiting seat, a cross arm body is arranged above the cutting table, and a cutting groove is formed in the cross arm body. And the outer wall of the cross arm body is inserted into the cutting limiting groove, a cutting machine is arranged on the upper portion of the interior of the cutting limiting seat, and the cutting machine is located above the cross arm body. Through cooperation of the limiting cover, the through opening, the air extracting pump, the filter screen, the collecting cover, the mounting cover, the sealing ring and the air extracting opening, metal chippings generated during cross arm cutting can be sucked into the limiting cover and collected through the collecting cover, the metal chipping cleaning efficiency is improved, the cleanliness of the surface of the cutting table is kept, the collecting cover can be rapidly disassembled and assembled, and the labor intensity of workers is reduced. And the metal scraps collected in the collecting cover can be conveniently cleaned.

The invention relates to the technical field of building construction, and discloses a mechanical building construction trowelling device which comprises an anti-skid base, a trowelling mechanism is arranged on the left side of the anti-skid base, the trowelling mechanism comprises a supporting frame, and the bottom of the right side of the supporting frame is fixedly connected to the left side of the anti-skid base. A rack is fixedly embedded in the right side of the supporting frame, and a mounting frame is arranged on the outer wall of the supporting frame. A trowelling plate is driven to vertically move upwards to trowelling concrete on a wall surface, at the moment, the trowelling plate scrapes redundant concrete slurry, the concrete slurry falls into a collecting cover, and meanwhile a driving shaft and a spiral blade are driven to rotate in the collecting cover; and the slurry in the collecting cover is conveyed into the storage frame through the conveying hose and the discharging pipe, so that the device can drive the spiral blade to rotate while performing scraping operation on the wall surface, the scraped slurry is conveyed and recycled, and waste of the concrete slurry is reduced.

The utility model discloses an elevator buffer pile with a positioning and adjusting function, which comprises a mounting base, a groove is arranged on the upper surface of the mounting base, an adjusting lead screw is rotatably connected to the inner wall of the groove of the mounting base, two transmission sliders are slidably connected to the inner wall of the groove of the mounting base, and a support rotating arm is rotatably connected to the upper end of each transmission slider. The elevator buffer pile with the positioning and adjusting functions is provided with a supporting sliding plate and a first friction block, when the elevator buffer pile works, replacement is facilitated through a detachable contact baffle, so that the contact effect is kept, after an upper connecting block is extruded, a first toothed plate is driven by the supporting sliding plate to slide downwards and compress a spring, and the first toothed plate drives a linkage gear to rotate; the linkage gear drives the second toothed plate to ascend, the inclined surface of the first friction block is pushed through the arc-shaped design of the second toothed plate, the first friction block horizontally slides, friction force is pressed on the side face of the upper connecting block through the first friction block, and therefore damping is improved for buffering.
