UGV bridging system includes a first end of a first elongated span of a hinged bridge structure disposed on a deployment support bracket which is secured to a UGV. A second elongated span is hingedly supported at a second end of the first elongated span opposed from the first end. A tension element applies a tension force to the first elongated span at a location intermediate the first and second ends. The tension force secures the first elongated span in a stowed position adjacent the deployment support bracket. A retention element associated with the deployment support bracket prevents the second elongated span from rotating about the hinge axis in response to a spring bias force. Deployment involves pivoting the first elongated span and concurrently releasing the second elongated span from the retention element in response to the extending.

An assembly for budding a pre-fabricated modular boat dock structure is disclosed. The assembly is designed to be modular so it can be fabricated in a shop environment and then installed by assembling it on site. The assembly is further designed to enable the individual component modules to be powder coated prior to installation so that the pre-fabricated modular boat dock will be rust resistant and have a much longer expected lifespan than a custom boat dock which is built on site would have. The pre-fabricated modular boat dock structure has a pleasing aesthetic appearance after having been powder coated and is useful in extending the life of a boat dock structure used to shelter boats stored immediately adjacent to a body of water.

In conclusion, the camouflage type long-span automatic rapid-extension emergency bridge is reasonable in structural design. In the event of an emergency, the temporary emergencybridge can be quickly constructed so as to facilitate the passage of people and vehicles.

The invention discloses a telescopic trestle attached to a cantilever beam of a self-elevating drilling platform and an application method thereof. The telescopic trestle is installed on the side wall of the cantilever beam of the self-elevating platform; the telescopic trestle includes a top supporting device, a mechanical transmission device, a trestle Fixed section, movable section of trestle, guide rail, folding guardrail, crawler-type trunking, telescopic inclined ladder, implantation mechanism. The telescopic trestle bridge provided by the present invention realizes the connection between the jack-up drilling platform and the fixed platform by virtue of the characteristics of the cantilever beam of the jack-up drilling platform and its own foldable and telescopic features, improves the working range of the trestle bridge, and saves the platform The installation space has changed the construction form of the traditional trestle bridge and saved the labor cost of trestle construction.

A pedestrian overbridge vehicle comprises a vehicle chassis. Hydraulic cylinder supporting legs are distributed below a frame of the vehicle chassis, a control cabinet is arranged on the frame of the vehicle chassis, the frame of the vehicle chassis is connected with a platform through distributed lifting hydraulic cylinders, the rear end of the platform is connected with an overbridge stairway and provided with an overbridge stairway winding mechanism, and the platform surface of the platform is provided with an overbridge body capable of stretching out and drawing back towards one side of a vehicle body; the overbridge body is provided with two rows of vertical shafts which are arranged longitudinally, hydraulic cylinder type telescopic cross pull rods and fixed cross pull rods, wherein the hydraulic cylinder type telescopic cross pull rods and the fixed cross pull rods are arranged longitudinally and alternatively and symmetrically arranged in an up-and-down mode; the two ends of each hydraulic cylinder type telescopic cross pull rod and the two ends of each fixed cross pull rod are in hinged connection with the corresponding vertical shafts, an overbridge body side plate is arranged between every two adjacent vertical shafts and is in hinged connection with the vertical shafts, and the inner side of the lower portion of each overbridge body side plate is provided with towing parts used for being connected with overbridge floor plates; one end of the overbridge body is connected with the platform, and the other end of the overbridge body is provided with overbridge body butt-joint connecting parts. The pedestrian overbridge vehicle can be used for composing a temporary pedestrian overbridge easily, conveniently and rapidly.

The invention discloses a shape-changing bridge for garden landscape, and relates to the field of garden landscape bridges. The shape-changing bridge comprises lake shores, a bridge plate and liftingmechanisms. The bridge plate is erected between the opposite two lake shores. First grooves matched with the end of the bridge plate are formed in the tops of the faces, close to each other, of the two lake shores. Second grooves are formed in the upper surfaces of the lake shores. A plurality of through holes communicating with the first grooves are formed in one lateral wall of the second groove. Fixing mechanisms connected with the end face of the bridge plate are mounted in the second grooves. The fixing mechanisms comprise stopping blocks, ropes and springs. The stopping blocks are slidably connected with the bottom inner walls of the second grooves. One lateral faces of the stopping blocks are fixedly connected with one ends of the ropes. The other ends of the ropes penetrate throughthe through holes and are fixedly connected with the end face of the bridge plate. Through the rubber bridge plate connected between the two lake shores and the fixing mechanisms and the lifting mechanisms used for improving stability and safety of the bridge plate, normal passage of persons is guaranteed, and ornamental value and enjoyment of the shape-changing bridge are improved.
