The present application discloses a kind of track leveling equipment for railway track laying construction, it is related to track traffic equipment technical field, the present application includes track and tamping car, further include: two leveling components, leveling component is used to the ballast around the sleeper is leveled and is handled, the leveling component includes fixed plate, and fixed plate bottom sliding installation has push flat plate, push flat plate is installed on ballast take-off mechanism, ballast take-off mechanism is used to the ballast around the sleeper is collected or the ballast of collected discharge according to the moving distance of push flat plate relative to fixed plate.Occupation is in: can be self-adapting leveling before tamping and real-time sensing ballast compactness and height, and utilize the displacement of push flat plate in leveling process automatically stepless regulation tamping vibration intensity, while the displacement of push flat plate can also trigger ballast take-off mechanism, realize the collection of excess ballast or the release filling of collected ballast, greatly improve tamping quality, energy efficiency and track laying precision.

This invention provides a method for controlling the travel path based on monocular vision recognition and an unmanned laying vehicle for crack-resistant base fabric, belonging to the technical field of machine vision recognition. The method includes using a monocular video acquisition device to collect video information of a target reference object on the crack-resistant base fabric laying equipment and converting it into image data to determine the initial center coordinate position of the target reference object in the image; adjusting the acquisition angle of the monocular image acquisition device on the target reference object according to the initial center coordinate position of the target reference object in the image, so that the distance between the initial center coordinate position of the target reference object in the image and a preset target center coordinate position in the image meets a preset initial distance; acquiring the travel center coordinate position of the target reference object in the image in real time and calculating the deviation between the travel center coordinate position and the target center coordinate position; and controlling the travel path based on the calculated deviation. This invention can significantly improve the flatness and efficiency of crack-resistant base fabric laying and effectively reduce labor costs.

The invention discloses a winding forming die for a tail stay tube of an unmanned aerial vehicle. The winding forming die comprises a mandrel, a small-head yarn blocking ring, a large-head yarn blocking ring, a pressing ring, a force application ring and a clamping shaft. The mandrel is the main part of the whole die, is consistent with the tube surface of the tail boom in shape and is used for winding the tube surface of the tail boom; the small-head yarn blocking ring and the large-head yarn blocking ring are of an annular flange plate and nail-shaped structure, are fixed to the mandrel through bolts and are used for blocking yarn during winding. The pressing ring is used for pressing the flange of the small end of the tail stay tube, the force application ring and the corresponding shaft are provided with threaded holes used for applying pressure to the pressing ring, the flange of the tail stay tube is pressed by applying force through the bolt, and the forming quality of the flange of the tail stay tube is guaranteed. The clamping shaft is used for clamping the driving end of the winding machine when the tail supporting pipe is wound. The winding forming mold for the tail stay tube of the unmanned aerial vehicle can guarantee the product quality of the tail stay tube, and is reasonable in structural design, convenient to demold and convenient to use.

This invention discloses a spherical support plate for a flexible horizontal fall arrestor for towers, comprising a spring damping device with a guide rod; a fixing fitting including a support plate with a reinforcing seat on one side, the guide holes on the support plate and the reinforcing seat being concentric and having the same diameter; and a support rod with a limiting ring, one end connected to the reinforcing seat and the other end having an external threaded section; a first nut and a second nut are threaded onto the external threaded section; wherein the guide rod passes through the guide holes on the support plate and the reinforcing seat. This invention features shock absorption for flexible guide rails and a simplified structure.

The application discloses a construction method of ecological revetment, which comprises the following steps: a, preparation before construction; b, digging a base groove; c, laying the base groove; d, installation of a limiting seat; and e, setting a planting groove. The application divides the revetment along the line, carries out sectional construction, firstly sets a water retaining wall to separate the water of a river channel from a construction section, then digs a base groove and flattens the base groove, secondly lays geotechnical cloth on the surface of the base groove in sections through a laying trolley, one end of the geotechnical cloth laid later is pressed on the geotechnical cloth laid earlier to ensure seamless connection between the geotechnical cloths, sand and stone layers are filled after the geotechnical cloth is laid, a steel mesh is arranged on the sand and stone layers, and a concrete layer is poured to ensure the structural strength of the revetment, limiting blocks at the bottom of the limiting seat are inserted into limiting holes for positioning and installation, then an installation frame and a grid are installed on the concrete layer, the grid divides the installation frame into a plurality of planting grooves, and the planting grooves are used for planting green plants.
