The specific embodiment
With reference to the accompanying drawings 1, the specific embodiment of the present utility model is described in further detail.
With reference to Fig. 1, two gantry lifting turnover machine comprises: concrete foundation 1, installation adjustable plate 2, portal frame 3, maintenance cat ladder 4, hoisting mechanism 5, balance weight mechanism 6, safety barrier 7, clamping tooling 8, workpiece (cantilever crane of cement pump truck) 9, workpiece conveying equipment 10, control cabinet 11, switching mechanism 12.
Two portal frames 3 are arranged on welding post two ends in opposite directions and over the ground, thus can be in pairs supporting, jointly praise a clamping tooling 8; The two ends of clamping tooling be connected with hoisting mechanism 5 on two portal frames respectively (should use corresponding clamping tooling for different length, the width of workpiece).Two similar two legs of column A6(of each portal frame) divide both sides across the ground rail; The ground rail 13 that is used for transmitting workpiece is laid on the central authorities of two columns (visible two the ground rails of figure are laid in rail hole, ground), and this ground rail extends to adjacent stations after passing through respectively two portal frames along the line of centres of two portal frames.Workpiece conveying equipment 10 moves along the ground rail, successively workpiece is delivered to adjacent station, processes by setup program.
In described hoisting mechanism (referring to Fig. 2, Fig. 3), slide rail A4 vertically is arranged on the column A6 of portal frame upper (portal frame both sides respectively configure a slide rail), riser A5 is positioned on slide rail slidably by corresponding slide block A5-1, by the preferred servomotor of motor A1() the screw mechanism A2 that drives orders about riser and moves up and down along slide rail.In Fig. 3 as seen: the lower end of leading screw A7 is connected with check plate A9 on Connection Block A10 by bearing pin A8; Motor orders about screw (in figure, screw omits) and rotates, and screw mandrel is just vertically driven, and riser namely is being driven and is moving up and down.
