A lorry-mounted crane special for railways comprises a rotary base, and a rotary table is disposed on the rotary base; the rotary table is connected with crane arms, and the crane arms comprise a rotation arm and a telescopic arm; the outer end of the telescopic arm is connected with a suspension-hook support arm; the lower part of the suspension-hook support arm is connected with a far-end suspension hook; a telescopic oil cylinder is connected between the rotation arm and the rotary table; the lower part of the rotary arm is provided with a slide way; an electric hoist is installed in the slide way and is capable of rolling along the slide way; and the lower part of the electric hoist is connected with a near-end suspension hook. The lorry-mounted crane special for railways is installed on a railway vehicle and is used for loading and unloading works of materials, tools and equipment needed in railway construction and maintenance. The lorry-mounted crane special for railways solves the problem that hoisting work usually needs to raise an arm. By using the lorry-mounted crane special for railways, a heavy object is directly hung on the far-end suspension hook of the suspension-hook support arm without depending on a steel wire rope for hoisting when hoisting is performed, loaded telescoping can be optionally performed through the crane arm and the heavy object can be hoisted to a needed position, also due to the fact that the lower part of the electric cucurbit is provided with the near-end suspension hook, close-range hoisting work can be realized, and blind areas do not exist in the working level scope. By using the lorry-mounted crane special for railways, the working efficiency is improved, the working height is increased, and operation is convenient.

The invention discloses an assembly method for intelligent special fire extinguishing bombs for unmanned aerial vehicles, which belongs to the field of fire extinguishing bombs, and includes a shell, an inner isolation tube, a booster device, a front connector, a rear connector, a sensor assembly and a power propulsion device; the shell , the inner isolation tube, the front connector and the rear connector are sealed to form a storage space for storing dry powder; the pressurization device includes a control chip, a detonator and a detonating cord; the sensor component includes a temperature sensor, an infrared sensor and a smoke sensor. The special intelligent fire extinguishing bomb for drones of the present invention, by sealing and isolating the fire extinguishing agent and the supercharging device, eliminates the hidden danger of misoperation caused by friction between the two under the action of high acceleration, and improves the working reliability; the control chip is combined with the sensor The configuration of the components realizes intelligent fire extinguishing, and at the same time, the structure is compact and reasonable, and the fire extinguishing bomb hits the fire extinguishing area more quickly and accurately to achieve the fire extinguishing goal, with faster response speed, higher working height and stronger fire extinguishing ability.

The invention discloses a portable electric energy meter, and the electric meter box comprises a box cover. The lower end of the box cover is connected with an electric meter box through a hinge. The lower end of the electric meter box is fixedly connected with a telescoping sleeve, and the interior of the telescoping sleeve is slidingly connected with a telescoping rod in a sleeved manner. The lower end of the telescoping rod is fixedly connected with a pedestal, and the lower end port of the telescoping sleeve is fixedly connected with a buffering spring. The lower end of the buffering sleeve is fixedly connected with the pedestal, and an inner side of the buffering spring is movably connected with the telescoping rod in a sleeved manner. The front and rear ends of two sides of the electric meter box are respectively in fixed connection with a threaded groove, and the inner sides of the threaded grooves are provided with supporting rods. The lower end face of each supporting rod is provided with a threaded projection, and the inner sides of the threaded grooves are in threaded connection with the threaded projections. The electric energy meter is novel in design, is enabled to be portable, is improved and enhanced in structure to certain extent, and is more convenient and safer for a technician to use.

The invention discloses boxed cotton transport equipment. The boxed cotton transport equipment structurally comprises a flat plate which is provided with traveling devices for driving the equipment tomove in a loop array form; steering devices which are located on the flat plate to enable the traveling devices to be turned are arranged between the traveling devices; and an adjusting conveying device capable of conducting height change so that cotton can be conveyed to different height positions is arranged above the steering devices. The boxed cotton transport equipment is provided with the steering devices and the adjusting conveying device, it is achieved that the equipment is precisely transported to the designated position, in addition, through the function of adjusting the height ofthe conveying structure, efficient conveying of cotton is achieved, the working efficiency of the equipment is improved, and the working height of the equipment is increased.
