The invention discloses a vehicle-carrying tray, which comprises a bottom frame consisting of a left edge beam and a right edge beam which are parallelly arranged and cross beams arranged between the left edge beam and a right edge beam. The vehicle-carrying tray is characterized in that: the vehicle-carrying tray also comprises an auxiliary frame which is positioned at the central position of the bottom frame and is respectively parallel to the left edge beam and the right edge beam; a first parking plate is paved between the auxiliary frame and the left edge beam, and a second parking plate is paved between the auxiliary frame and the right edge beam; one end of the first parking plate is vertically fixed with the left edge beam; the other end of the first parking plate and the auxiliary frame are vertically fixed relative to a side edge arranged on one side of the left edge beam; one end of the second parking plate is vertically fixed with the right edge beam; and the other end of the second parking plate and the auxiliary frame are vertically fixed relative to a side edge arranged on one side of the right edge beam. Compared with the prior art, the vehicle-carrying tray has the advantages that: the bottom frame of the vehicle-carrying tray is provided with the auxiliary frame, and the parking plates have small span and need thinner materials, so the raw materials are obviously saved and the cost is reduced; and the vehicle-carrying tray can also avoid direction shift in the process that a vehicle pulls in, and ensures that the vehicle parks at a correct position.

The invention discloses a fully-automatic emergency escape door for a large and medium passenger car. The fully-automatic emergency escape door comprises a door frame arranged on the side face of a car body; the bottom of the door frame is flush with the floor of a compartment, an ascending window and a pedal are mounted at the top and the bottom of the door frame correspondingly in a hinged mode,and an elastic opening structure and an automatic retracting mechanism are arranged between the door frame and the ascending window as well as between the door window and the pedal; when the passenger car is in use, the ascending window and the pedal are usually folded into the door frame to be connected with the car body into a whole; during emergency escape, the ascending window and the pedal are automatically bounced to form an escape channel; and after escape is completed, the ascending window and the pedal are automatically retracted. The fully-automatic emergency escape door has the advantages that the manufacturing cost is low, opening is convenient, the used time is extremely short, evacuation is rapid, and practicality and reliability are achieved.

A semi-automatic three-dimensional underground garage belongs to the field of underground construction engineering. The road sideline, road center line, ground, garage entrance, and garage exit of the ground structure are the above-ground parts of the garage; the card reader, car lift, elevator door, and hoist are the lifting and lowering mechanisms of the garage; the passenger elevator, walking ladder, Ventilation pipe wells, garage columns, garage main structure, parking spaces, and equipment pipes are the underground part of the garage. The structure of the garage is symmetrical and simple, the main structural material is reinforced concrete or steel pipe concrete, and the cost is low; the layout of the structural column spacing is reasonable, and the usable area of ​​the garage is maximized. At the same time, the garage is equipped with auxiliary facilities, which can meet the operation and management of the garage, and can also deal with emergencies to ensure safe use.

The invention relates to a car platform for non-avoidance stereoscopic parking equipment. The car platform comprises a bearing plate, flanges, a base frame and slopes; the flanges are arranged on left and right sides of the bearing plate, the base frame is arranged at the bottom of the bearing plate, and the slopes are arranged at the front and rear ends of the bearing plate, wherein wheel spacing grooves are formed in the front and rear ends of the top of the bearing plate, and a floating board is arranged in the wheel spacing groove; a support spring and a support rod are arranged at the bottom of the floating board, and an abdicating hole is formed in the base frame with respect to the support rod. The car platform is simple and reasonable in structure, when the car platform lands, the car is convenient to pull out; when the car platform leaves from the ground, the car on the car platform can effectively prevent from car sliding.

The embodiment of the invention discloses a single-portal crane span oblique beam falling construction method and construction equipment. The construction method comprises the following steps that beam-transporting carriers are conveyed to the portion between crane rails; a portal crane is operated to lift a prefabricated U-type beam from a beam making pedestal; the portal crane is operated to move along the crane rails, and a fixed end lifting apparatus is located above the rear beam-transporting carrier; the portal crane is operated to make the fixed end lifting apparatus separated from oneend of the prefabricated U-type beam, and the fixed end lifting apparatus is lifted; the portal crane is operated to move so that a rotary lifting apparatus and the other end of the prefabricated U-type beam can be located above the front beam-transporting carrier; and the rotary lifting apparatus is operated to be separated from the other end of the prefabricated U-type beam, and the rotary lifting apparatus is lifted. According to the method, the rotary lifting apparatus is exquisitely used for rotating a beam body in the conveying process, so that the beam-transporting carriers are driven away from the beam falling area after beam falling conveniently, and the operation efficiency is improved.
