The invention provides a bridge detection device. A driving car and a driven car are connected with connection frames respectively; the bottom ends of the connection frames are fixedly connected with butt joint driving heads; each butt joint driving head is internally provided with a movable arm which can move transversely at the bottom of a bridge under the driving of the butt joint driving head; in opposite end parts of the two movable arms which are opposite to each other in the transverse direction, one end part is provided with a male head and the other opposite end part is provided with a female head; the two movable arms which are opposite to each other in the transverse direction are in butt joint and released by matching the male head with the female head respectively under the driving of the butt joint driving heads, and a pair of transverse guide rails are formed by the two movable arms which are opposite to each other in the transverse direction; and the transverse guide rails are provided with driving wheels at the two ends of a working walking platform respectively, and the working walking platform moves transversely on the transverse guide rails. When the device provided by the invention is used for overhauling the bridge, a working platform and a retractable arm are at a simply supported beam mechanical state, so that the safety of workers is effectively guaranteed and the device can automatically keep away from obstacles including piers and the like; and the device does not occupy a traffic lane, can work flexibly and conveniently, and has high construction efficiency and low production cost.

The invention relates to the technical field of rail high-speed rail, in particular to a small trolley for rail high-speed rail that is easy to fold, including two winding posts, and a positioning mechanism is arranged on one side of the outer wall of the two winding posts. The outer wall on the opposite side of the winding post is fixedly connected with a folding rod through a positioning mechanism, and the outer wall at the middle of the two folding rods is provided with a connecting mechanism, and the outer wall at the end of the two folding rods is far away from the winding post. Both of them are fixedly connected with supporting columns through positioning mechanism, and there are equidistantly distributed horizontal bars welded between the two coiling columns and between the two supporting columns, and the outer walls of the two supporting columns are provided with plug-in mechanisms , and the two support columns are connected with connecting rods through the plug-in mechanism. The beneficial effect of the invention is that the trolley including the bucket can be completely folded, and when not in use, the space occupied by the trolley can be effectively reduced and the trolley is more convenient to carry.

The invention relates to a meat food preservation device during cold-chain logistics. The meat food preservation device during cold-chain logistics comprises a vehicle body and a refrigeration container. The refrigeration container is fixedly installed on the vehicle body; a tank is fixedly installed in the middle of the bottom part in the refrigeration container; the top part of the tank is opened; rectangular holes are symmetrically formed in the front side face and the back side face of the tank; rectangular plates are arranged in the rectangular holes; the upper ends of the rectangular plates are matched with the top parts in the corresponding rectangular holes in a contacting way; the lower ends of the rectangular plates are matched with the bottom parts in the corresponding rectangular holes in a contacting way; the right end of each rectangular plate is fixedly connected with the right side in the corresponding rectangular hole through a first electric telescopic rod; and each rectangular plate can move back and forth along a length direction of the corresponding rectangular hole. Through a simple mechanical design, the meat food preservation device during cold-chain logistics provided by the invention can be used for automatically simply packing preservative films on meat food, and workers only need to simply treat two non-tightly packed end parts of the simply packed meat food, so that being assisted by the meat food preservation device provided by the invention, the workers can effectively improve preservative film packing speed for the meat food, and a preservative film packing part can move along with the vehicle body.

The invention provides a novel multifunctional air-conditioning umbrella. The novel multifunctional air-conditioning umbrella comprises an umbrella role, an umbrella rib, an umbrella fabric, an air ice storage and refrigeration device, an air evaporative cooling device, a spiral lifting device, a power supply system and a control system, wherein the power supply system is used for supplying power; the control system is used for controlling the air-conditioning umbrella to work; the umbrella rib is mounted at the upper part of the umbrella pole; the umbrella fabric is supported by the umbrella rib; the air ice storage and refrigeration device, the air evaporative cooling device, the power supply device and the control system are all arranged at the lower part of the umbrella pole; the spiral lifting device is arranged on an umbrella tip above the umbrella fabric; and a plurality of air outlets and a plurality of spray nozzles are arranged on the umbrella rib, cold air is conveyed to the air outlets through the air ice storage and refrigeration device, and water is conveyed to the spray nozzles through the air evaporative cooling device. The novel multifunctional air-conditioning umbrella has the advantages that the traditional limitation that 'an umbrella has to be held by hand' is avoided, so that both hands can be liberated, and meanwhile, air under the umbrella can be cooled down, so that a comfortable environment can be provided for a user in hot summer.
