The specific embodiment
As shown in Figure 1-2, a kind of passenger train bolster joist maintenance displacement device, comprise support 17, electrical motor 1, the reductor 2 with auto-lock function, driving device 3 and for the fixing clamping fixed mechanism 4 at bolster joist two ends, one end of clamping fixed mechanism 4 is connected with driving device 3 by active axis of revolution, driving device 3 is fixed on support 17, the other end of clamping fixed mechanism 4 is fixed on support 17 by driven axis of revolution, and electrical motor 1 is connected with driving device 3 by reductor 2.The utility model is simple in structure, principle is applicable, practical and convenient, be applicable to various passenger car bogie bolster, the clamping of joist, upset.
Support 17 and clamping fixed mechanism 4 form double bracket structure, and clamping fixed mechanism 4 is for fixing by maintenance object, and clamping fixed mechanism 4 can overturn under the drive of electrical motor 1, reductor 2 and driving device 3.Preferably, be provided with the mounting hole consistent with the existing position of mounting hole of bolster joist on clamping fixed mechanism 4, bolster joist is fixed on clamping fixed mechanism 4 by the mounting hole on existing mounting hole and clamping fixed mechanism 4, and clamping workpiece is firmly convenient.
Reductor 2 is two-stage worm reduction gears 2, has auto-lock function, operates steadily, and workpiece can be realized 360 ° and rotates and be parked in arbitrarily angled.The transmitting ratio of two-stage worm reduction gear 2 is preferably 900:1, can freely the overturn workpiece of 500 ㎏ weight of Intensity Design.
