Abstract
The utility model relates to a transmission device for a bogie of a bogie type heat treatment furnace, in particular to a transmission device for a bogie of a frequency control motor train unit, which comprises a bogie body; a driving wheel and a driven wheel are arranged at the bottom of the bogie body; lead rails along which the driving wheel and the driven wheel can slide are laid on the ground; a drive mechanism arranged on the driving wheel comprises a frequency converting motor, a speed reducer and a transmission shaft; and the output end of the frequency converting motor is connected with the speed reducer which is connected with the driving wheel through the transmission shaft. The drive mechanism is arranged at the bottom of the bogie body, so the structure of the bogie is compact, thus greatly reducing the occupying area and avoiding underground project, which is convenient for the installation and operation of the bogie. The transmission device adopts frequency control, so the transmission speed is adjustable, thereby effectively improving the work efficiency.
Description
Technical field
The utility model relates to the transmission device of chassis in the car-type heat treating furnace, especially a kind of frequency control EMUs chassis transmission device.
Background technology
Since the reform and opening-up, China's plastics industry, mould industry, power industry, wind-powered electricity generation and big weight equipment manufacturing industry develop rapidly, increasing with the demand of steel to large-scale plastic-forming die steel, large gear with steel, macrotype axes series, and require more and more higher to the composition of material, performance, description, supply of material state etc.Annual import volumes of these materials of China's use at present and year consumption are very big.For this reason, domestic many units are developing the new special steel, according to the alloying composition design principle of steel and in conjunction with the truth of china natural resources and metallurgical technology, the new steel grade of development high-performance, long-life, the valuable alloying element consumption of reduction replaces expensive import steel.Making great efforts raising metallurgy and forging rolling quality, optimizing Technology for Heating Processing simultaneously.Because above-mentioned new material belongs to large-scale steel-casting more, general Equipment for Heating Processing can not satisfy its heat treatment requirements, exploitation also development meets the energy policy of China, and heat-treatment furnace large-scale, energy-conservation, efficient, with high content of technology and that have an independent intellectual property right becomes the task of top priority.
The chassis that car type furnace of the same type is in the market used generally all is that single motor band decelerator drives or employing cogwheel structure, and these transmission devices all exist some shortcomings: the transmission speed of design is single, is unfavorable for enhancing productivity; Need driving mechanism is hidden in underground, the civil engineering workload is big, installs inconvenient.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problems of the technologies described above, the utility model provides a kind of frequency control EMUs chassis transmission device, and frequency control is adopted in the driving of chassis, has effectively improved production efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of frequency control EMUs chassis transmission device, has the chassis car body, chassis car body bottom is provided with driving wheel and driven pulley, be equipped with on the ground and can make driving wheel and driven pulley guide rail along its slip, the driving mechanism that is provided with on the driving wheel comprises variable-frequency motor, decelerator and power transmission shaft, the output connection reducer of variable-frequency motor, decelerator is in transmission connection by power transmission shaft and driving wheel.
According to the needs of loading capacity, many group driving wheels can be set, the interlaced uniform both sides of driving wheel and driven pulley.
The beneficial effects of the utility model are: driving mechanism is arranged on chassis car body bottom, makes the chassis compact conformation, significantly reduced floor space, avoided underground engineering, and be convenient to installation and operation; Adopt frequency control, transmission speed is adjustable, has improved operating efficiency effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. chassis car body, 2. driving wheel, 3. driven pulley, 4. guide rail, 5. variable-frequency motor, 6. decelerator, 7. power transmission shaft.
The specific embodiment
As shown in Figure 1, a kind of frequency control EMUs chassis transmission device, has chassis car body 1, chassis car body 1 bottom is provided with driving wheel 2 and driven pulley 3, driven pulley 3 does not show in the drawings, be equipped with on the ground and can make driving wheel 2 and driven pulley 3 guide rail 4 along its slip, the driving mechanism that is provided with on the driving wheel 2 comprises variable-frequency motor 5, decelerator 6 and power transmission shaft 7, the output connection reducer 6 of variable-frequency motor 5, decelerator 6 is in transmission connection by power transmission shaft 7 and driving wheel 2, according to the needs of loading capacity, driving wheel 2 has many groups, driving wheel 2 and driven pulley 3 interlaced uniform both sides.
This chassis is made up of steel construction lead frame part and refractory material masonry, adopts frequency control to drive.The speed of chassis can be set at a slow speed, wait fast, at a slow speed three sections speed.Be equipped with guide rail 4 on the outer mill floor of stove.During chassis work, earlier fire door is all opened; Fast chassis is shifted out in stove, when station, become at a slow speed and stop.With the workshop crane workpiece to be heated is put on the chassis parallels, when chassis enters in the stove, move the same, advance fast, stop slowly when putting in place, prevent the collision of chassis and body of heater, shove charge finishes, close fire door, furnace bottom electric pushrod hold down gag starts simultaneously, after furnace bottom and the oven door sealing, stove work, workpiece is heated, treat that operation finishes after, the electric pushrod that unclamps fire door is door opened to opening fully, furnace bottom electric pushrod hold down gag unclamps simultaneously, after opening the furnace bottom sealing, chassis is left outside the stove, unloads workpiece by the workshop crane.
