The invention belongs to the field of lifting, especially the lifting device for loading and unloading equipment for electric maintenance vehicles. It is inconvenient to disassemble and fix large-scale equipment for existing maintenance equipment, which delays work efficiency. Bumping occurs in the middle and cannot meet the needs of use. The following plan is proposed, which includes the maintenance vehicle body. The top of the maintenance vehicle body is symmetrically provided with a fixed bracket, and the side of the fixed bracket away from the maintenance vehicle body is equipped bracket, and one end of the installation bracket is fixedly installed on the body of the maintenance vehicle, a movable bracket is installed inside the installation bracket, and the movable bracket extends to the outside of the installation bracket, and the side of the movable bracket and the installation bracket that are close to each other is provided with the same A movable slot, the invention has a reasonable structure, can avoid collisions of large equipment such as transformers when moving, can improve work efficiency at the same time, and meets the needs of use.

The invention discloses a roller shutter door safety lock. The roller shutter door safety lock comprises a wall, a channel penetrating in the front-rear direction is formed in the wall, safety devices are arranged in the inner walls of the left side and the right side of the channel, each safety device comprises through grooves which are symmetrically formed in the inner walls of the left side and the right side of the channel, and fixing blocks are fixedly connected to the inner walls of the sides, close to the symmetrical center, of the through grooves; and rotating cavities with openings deviating from the symmetrical center are formed in the fixing blocks, and connecting shafts are rotatably connected between the upper inner walls and the lower inner walls of the rotating cavities. The roller shutter door safety lock is easy to operate and convenient to use, the winding speed during retracting of a roller shutter door can be automatically limited, manual traction is avoided, personal safety is ensured, meanwhile, the winding speed is not limited when the roller shutter door is expanded, convenience and quickness are achieved, and the channel can be quickly closed.

The invention discloses a cable laying assisting device. One side of a transmission motor is provided with a double-headed reducer; one end of each first transmission shaft is provided with a drivinggear; one end of each second transmission shaft is provided with a driven gear that is engaged with the corresponding driving gear; one side of each second transmission shaft is provided with a lifting device; the input shaft of each screw jack is connected with the corresponding second transmission shaft through a coupling; the upper part of each screw sleeve I is provided with a screw sleeve III; the upper parts of the supporting plates is provided with a rotating device; the rotating device comprises bearing seats II, rotating shafts I, chucks, and a rotating shaft II; the bearing seats IIare fixedly mounted on the upper parts of the supporting plates respectively; the bearing seats II are internally provided with bearings respectively; the rotating shafts I are installed in bearing inner rings inside the bearing seats II respectively; one end of each rotating shaft I is fixedly connected with the corresponding chuck; and two ends of the rotating shaft II are respectively installedinside the chucks at two sides. The cable laying assisting device of the invention is of an integrated structure. With the cable laying assisting device adopted, operation can be completed by one person, so that work efficiency is high; and the lifting device adopts a linkage manner, and the lifting rate of the lifting device is uniform, and therefore, the inclination of a cable reel can be avoided.

The invention discloses a high-voltage transmission line routing robot, which relates to the technical field of high-voltage transmission lines, and includes a device main body, a fixing clip and a clamping block. A storage box is embedded in the right side of the main body. The invention installs a rotating wheel, When the main body of the device is moving along the transmission line through the rotating wheel, when the rotating wheel is driven by the second motor to rotate, the rubber ring will always expand outward through the elastic force of the first spring, so that the rubber ring can closely fit the power transmission lines of different sizes. line, so that it is not easy to slip between the rotating wheel and the transmission line, and the roller will always be tightly attached to the lower end of the transmission line through the elastic force of the second spring, and the concave arc surface in the middle of the outer surface of the roller can effectively fit the outer surface of the transmission line. The firmness between the rotating wheel and the transmission line can be improved through the roller, so as to avoid the easy falling of the rotating wheel when it rotates and moves along the transmission line.

The invention relates to the technical field of a high-voltage line laying device and particularly relates to an electric power iron tower high-voltage line pre-tightening device. The high-voltage line pre-tightening device of an electric power iron tower comprises a vertical plate, wherein a cross beam plate is transversely welded at an upper end of the right side of the vertical plate, a throughhole penetrating left and right is formed in an upper end of the vertical plate, and an electric telescopic rod and a side support are vertically welded at upper and lower ends of the left side of the vertical plate. The high-voltage line laying device is advantaged in that winding and fixing of a high-voltage cable are achieved through cooperation of a driving motor and a pulley, so stretching and laying of the high-voltage cable are achieved through rotation of a motor, manual pulling is avoided, operation safety and convenience are greatly improved, and high-altitude operation is more convenient, three-stage pre-tightening is realized through motor driving, extension of a telescopic rod and stretching of a balancing weight, so adjustment of pre-tightening force is refined, the magnitude of the pre-tightening force on the high-voltage cable is convenient to control, excessive stretching is avoided, and a purpose of fine adjustment is realized.
