The utility model discloses a road construction trench excavation equipment relates to road construction technical field, including the drill rod main part, and the drill rod main part is equipped with the intercepting roof, and the intercepting roof is fixedly installed on the drill rod main part through the fixed mechanism, and the intercepting roof is evenly distributed with a plurality of intercepting mesh holes, and the outside of intercepting roof is equipped with the intercepting side cover, and the outside of intercepting side cover is evenly provided with a plurality of intercepting straight seams along the circumferential direction, and the top of intercepting roof is fixedly installed with the symmetrical guide rod, and the intercepting side cover is slidingly connected on the outer surface of guide rod, and the top of guide rod is fixedly connected with the anti -drop cap, the utility model discloses through the setting of intercepting mesh hole, intercepting straight seam, and air can be relatively smooth through, make air flow relatively more dispersed and orderly, this reduces the strong air vortex and air flow impact that produces because of intercepting roof quick lift, and the disturbance of air in intercepting roof, intercepting side cover is relatively small, avoids producing the relatively large dust influence operator observation construction condition.

The utility model belongs to the technical field of electromagnetic loading, and particularly relates to a long-service-life electromagnetic drive loading device and an electromagnetic riveting device, which comprise a discharge coil arranged on a coil framework. A discharge coil and a coil framework are mounted in the metal magnetic conductive shell; the annular driving sheet is mounted on the driving sheet framework, and the annular driving sheet and the discharge coil are oppositely arranged; a cooling channel used for cooling the annular driving piece is arranged in the driving piece framework. The amplifier is fixedly connected with the driving sheet framework, and the amplifier is used for installing a driven part; the metal reset guide rod is arranged in the metal magnetic conductive shell, penetrates through the coil framework and the driving sheet framework and then is fixedly connected with the amplifier, and a reset piece is arranged on the metal reset guide rod; according to the utility model, the heat dissipation capability of the coil is improved, thereby improving the electromagnetic driving efficiency and prolonging the service life.
