The invention relates to a road block removal device of a fire engine, which belongs to the technical field of special vehicles. The road block removal device of the fire engine comprises a pair of crossbeams of a chassis frame. The road block removal device comprises a bracket, an upper connecting rod rack, a lower connecting rod rack, a shoveling plate seat, a main shoveling plate and a pair of acting cylinders, wherein the bracket is fixed between the crossbeams of the chassis frame; moreover, the bracket is positioned at one ends of the crossbeams of the chassis frame, which are towards an engine head of a fire engine; the upper connecting rod rack is connected with the bracket; the lower connecting rod rack is connected with the bracket; one side of the shoveling plate seat is connected with the upper connecting rod rack; moreover, the shoveling plate seat is also connected with the lower connecting rod rack, a first inclined plane and a second inclined plane are formed at the other side of the shoveling plate seat, and the first inclined plane and the second inclined plane form a reversed V shape with each other; the main shoveling plate is fixed with the first inclined plane and the second inclined plane, and a side shoveling plate is respectively connected in the height directions of both sides of the main shoveling plate; the acting cylinders are hinged on the bracket; and moreover, the columns of the acting cylinders are connected with the shoveling plate seat. During block removal, the road block removal device of the fire engine is very beneficial to expelling blocks towards both sides, and the resistance can be decreased; moreover, the efficiency of block removal is enhanced, and the vehicular power consumption is saved; the road block removal device of the fire engine can adapt to the effect of flexibility at a working state and a non-working state; and the road block removal device of the fire engine has a simple structure and is beneficial to manufacture, installation and maintenance.

The invention relates to a suspending rod special for suspending a barrier-cleaning device. The suspending rod comprises a hinge plate, a suspending head and a cable penetrating device, wherein the hinge plate is arranged at the front end of an insulating rod; the suspending head is arranged on the hinge plate in a swinging form; the cable penetrating device is arranged on the lower part of the insulating rod and is used for controlling the suspending head to open and close; the suspending head comprises a Y-shaped head; a hanging rod and a limiting hook which are connected with each other are respectively arranged on the two sides of the opening of the Y-shaped head; a reel wound with a cable is arranged in the insulating rod; and the cable penetrates through the cable penetrating device and then is connected with the limiting hook. The suspending rod can be used for picking the barrier-cleaning device on the ground to the position of the wire and then controlling the barrier-cleaning device to unhook on the ground so as to complete the suspension, so that a large amount of suspending time is saved, the quantity of personnel operation is saved, and the wire barrier cleaning efficiency is increased.

The invention discloses a high-altitude unmanned aerial vehicle for removing obstacles. A cutting device is fixed on the unmanned aerial vehicle by a cloud deck, and the cutting device and the cloud deck are in wireless connection with a cutting remote controller by a wireless emitter. The high-altitude unmanned aerial vehicle has the advantages of high obstacle removing efficiency, convenience in use and simplicity in operation, can deal with obstacle removing work in all altitudes, and even can deal with long-spanned obstacle removing tasks such as high mountains, deep gullies and rivers.

The invention discloses a special mechanical warehouse clearing device for mine bins. Two guide pulleys are installed on the front side of the top of the mine bin. A guide wire rope is fixed on the left and right sides of the top of the mine bin. Row of rake teeth, the front end of the rake teeth is gradually inclined downward relative to the rear end, the front end of the rake teeth is 2-6cm higher than the bottom of the rake wheel, the lower ends of the two traction wire ropes are fastened to the front end of the rake frame, and the upper end of the traction wire rope is wound around After passing through the corresponding guide pulleys, it is fastened to the front end of the sliding steel plate. The movable pulley is installed at the rear end of the sliding steel plate. The main wire rope of the winch goes around the movable pulley and then folds back for fixed installation. A guide tube is fixedly installed at the left and right ends of the sliding steel plate. , and each guide tube is sheathed on its corresponding guide wire rope.
