The invention discloses an automatic vehicle hoisting and translating device and belongs to the field of vehicle accessories. The automatic vehicle hoisting and translating device is composed of an even number of hoisting mechanisms and translating mechanisms, motors are arranged on the hoisting mechanisms and the translating mechanisms, the upper portions of the hoisting mechanisms are fixedly connected on a vehicle sill, the translating mechanisms are arranged on the lower portions of the hoisting mechanisms, lower lateral supports of the translating mechanisms are connected with a plurality of translating rollers and a plurality of translating motors, the translating rollers are connected with the translating motors, and all the motors are connected with receivers. The automatic hoisting and translating device is capable of rapidly and safely dealing with vehicle fault during driving and keeping driving road in smooth running.

The invention relates to a soil solidifier and a soil solidification method. The soil solidifier comprises 15 to 30 percent of fly ash, 4 to 15 percent of lime, 10 to 20 percent of sodium silicate, 8 to 20 percent of caustic soda, 5 to 16 percent of gypsum, 10 to 32 percent of common silicate cement, 0.5 to 3.5 percent of fluorite and 0 to 1.5 percent of sodium sulfate. During solidification of soil, the soil solidifier is tight, relatively low in contraction and swelling coefficient and extremely small in solidified soil body contraction amount; deformation and cracks which are caused by expansion with heat and contraction with cold because of temperature change are avoided; therefore, the solidified soil body is high in seepage resistance, freezing resistance and cracking resistance; the problems of low water stability, high dry cracking performance and simplicity in cracking during solidification of the soil by the conventional solidification material are well solved; and the solidified soil body has a relatively good heat isolation function. The soil solidification method is easy to construct, time-saving and labor-saving; the solidifier cannot be influenced by the temperature; the solidification time is short; the working efficiency is high; the working period can be greatly shortened; and the cost is reduced.

The invention relates to a crevasse plugging system and plugging method. The crevasse plugging system comprises a hanging bridge used for being suspended above a crevasse; the hanging bridge is provided with a plurality of pile holes, and a stopping pile rod is arranged in each pile hole in a penetrating manner; the lower end of each stopping pile rod is used for being inserted into a riverbed ofthe crevasse; and the crevasse plugging system further comprises a water stopping piece abutting against the stopping pile rod in the flood flowing direction to stop flood. Due to the fact that the two ends of the hanging bridge are correspondingly fixed to the two sides of the crevasse, a channel for an operator to pass through is formed, and it is avoided that a person performs operation in theflood; each hanging plate, suspending above the crevasse, of the hanging bridge is provided with the stopping pile rod in a penetrating manner, and the stopping pile rods are used for being inserted into the riverbed; the water stopping piece is placed on the side, close to the inner side of the crevasse, of each stopping pile rod; each water stopping piece is limited due to stopping by the corresponding stopping pile rod, and a role of stopping the flood temporarily can be played; and at the moment, soil and stone, sand bags and other filler are thrown into the side, backing onto the riverbed, of the water stopping pieces, and washing away by the flood is not likely to be caused, the crevasse plugging time is shortened, and the work efficiency is improved.

The invention relates to an arched bent suspension bridge structure which comprises a longitudinal main beam, a plurality of groups of transverse arch ribs are arranged on the main beam and stretch across the main beam, and vertical slings are arranged between the arch ribs and the main beam. The arch ribs stretch across the main beam, and the two ends of the arch ribs are provided with stress points, for example, the ground serves as the stress points. Vertical slings are arranged on the arch ribs, the slings take the arch ribs as stress points and provide upward pulling force for the main beam, so that no pier is arranged in a certain section of longitudinal range of the main beam, and the structure is particularly suitable for the conditions that roads are arranged on the ground below the main beam, pipelines and subways are arranged under the ground, and piers are not suitable for being arranged.

The invention discloses a high-voltage power transmission and distribution cable cross-road erection tool and a wire erection method, including a wire tension device, a wire release tension mechanism, a fast wire pull mechanism, a lead wire ray device, a cable traction rope, and at least two wire take-up brackets. Lead wires and cable pull ropes are sequentially connected to cables through mouse-shaped connectors, and the wire-taking bracket includes a base, a vertical pole and a wire-taking horizontal bar. The time required to use the machine tool is 1 / 4 of the original time, and only 2 operators are needed, and at least 5 people are required for the machine tools in the prior art; It will not affect road transport at all.

The invention discloses a dock boarding ladder. The boarding ladder comprises a guiding plate, a long ladder and a derrick ladder, the lower end of the long ladder is slidably connected with the guiding plate, the upper end of the long ladder is hinged to the bottom of the derrick ladder, and fixing parts connected with grooves and tongues in the ship side in a hung mode are further arranged on the outer walls of the derrick ladder. The dock boarding ladder is simple in structure and convenient to use and can adapt to different ship heights, the derrick ladder of the boarding ladder is hung onthe ship side, the derrick ladder is hinged to the long ladder, the lower end of the long ladder is connected with the guiding plate through a sliding structure, when the height of a ship is changed,the lower end of the long ladder slides on the guiding plate, thus an included angle between the long ladder and the derrick ladder is automatically adjusted to the optimal position and does not needto be adjusted all the time by a worker, the flexibility of the boarding ladder is improved, and the adaptability of the boarding ladder is expanded.
