Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of valve refractory test draw gear, comprises winch 1, retarder 2, controller 3, steel rope 4, assembly pulley 5, rail vehicle 6, track 7, coder 8, frequency converter 9.Described steel rope 4 is wound on the reel 10 of winch 1, two ends stretched out from reel 10 are connected with the front end of the rail vehicle 6 fallen within track 7 and end respectively through assembly pulley 5, in closed loop arrangement states, rail vehicle 6 is provided with water storage tank 12, the end of that one end respective carter car 6 of water storage tank 12; Described assembly pulley comprises n pulley, and n is not less than 4, the distance run can be needed to set according to rail vehicle 6, be advisable so that steel rope 4 is all stretching everywhere; The input and output side of described retarder 2 is connected with reel 10 with the motor 11 of winch 2 respectively; Described coder 8 is arranged on reel 10 main shaft of winch 1, and its signal feedback is connected to controller 3; The input interface of described frequency converter 9 is connected to controller 3, and output interface is connected to the motor 11 of winch 1.
After test condition all possesses, controller 3 sends advancement commands, winch 1 is started working, coder 8 also starts thereupon, and that one end steel rope 4 be connected with rail vehicle 6 end puts rope with reel 10, and that one end steel rope 4 be connected with rail vehicle 6 front end is with reel 10 rope closing, separate unit winch 2 put rope consistent with rope closing speed, relend help assembly pulley 5 guide effect into, steel rope 4 remains straight condition, thus the rail vehicle 6 driving conveying valve is steadily forward.
The impulse singla that controller 3 pairs of coders 8 feed back counts, when this numerical value reaches the advance process reduction of speed setting value preset, controller 3 sends reduction of speed instruction to frequency converter 9, the rail vehicle 6 started under the drive of multistage speed driving winch 1 is down to Ultra-Low Speed with S curve and is run, until counted number of pulses reach enter setting value time, controller 3 sends halt instruction and counting procedure is reset reset simultaneously, and frequency converter 9 stops exporting, and the rail vehicle 6 of heavy burden smoothly stops at target stop position.
After bonfire test, controller 3 sends retrogressing instruction, winch 1 task again, coder 8 also starts thereupon again, and that one end steel rope 4 be connected with rail vehicle 6 front end puts rope with reel 10, and that one end steel rope 4 be connected with rail vehicle 6 end is with reel 10 rope closing, separate unit winch 2 put rope consistent with rope closing speed, relend help assembly pulley 5 guide effect into, steel rope 4 remains straight condition, thus drives the rail vehicle 6 of conveying valve steadily to retreat.
The impulse singla that controller 3 pairs of coders 8 feed back counts, when this numerical value reaches the fallback procedures reduction of speed setting value preset, controller 3 sends reduction of speed instruction to frequency converter 9, the rail vehicle 6 started under the drive of multistage speed driving winch 1 is down to Ultra-Low Speed with S curve and is run, until counted number of pulses reach fall back on setting value time, controller 3 sends halt instruction and counting procedure is reset reset simultaneously, and frequency converter 9 stops exporting, and the rail vehicle 6 of heavy burden smoothly stops at target stop position.
