During concrete enforcement, vertical support middle part in vehicle frame both sides is provided with left and right guide rail, and lifting pedestal both sides are fixed left and right guide wheel assembly respectively, and left and right guide wheel assembly is located in the left and right guide rail.Be located in the left and right guide rail by left and right guide wheel assembly, guarantee that the lifting pedestal does not produce deflection when lifting.
During concrete enforcement, vehicle frame has front-wheel and trailing wheel, and trailing wheel is a universal wheel.
Hydraulic jack rises and can adopt handle adjusting or pin to step on multiple modes such as adjusting.
The utility model is adopted as the hydraulic drive lifting technology, realizes the lifting and the accurate lock function of equipment.The steady lift action of hydraulic jack jack-up, left and right guide wheel assembly make the lifting pedestal not produce deflection when lifting.
The beneficial effects of the utility model are: owing to adopt the hydraulic drive lifting technology, have lifting steadily, turn to light and flexible, characteristics such as easy to operate, safe and reliable, be the ideal tools that reduces labor intensity, enhances productivity, realizes the breaker safe transhipment.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is that the utility model embodiment master looks schematic diagram;
Fig. 2 is that schematic diagram is looked on the utility model embodiment right side.
Among the figure: 1, hydraulic jack 2, guide wheel assembly 3, sprocket wheel beam 4, movable sprocket wheel 5, crossbeam 6, bottom girder 7, guide rail 8, lifting chain 9, front-wheel 10, trailing wheel 11, vehicle frame 12, lifting pedestal
Embodiment
According to Fig. 1, shown in Figure 2, embodiment states to the utility model below:
High pressure middle switchgear running car, the lifting pedestal 12 that is held main circuit breaker by vehicle frame 11 and holder constitutes, and vehicle frame 11 is L shaped, and vehicle frame 11 has two left and right trailing wheels 9 and two left and right front-wheels 10, and left and right trailing wheel is a universal wheel; Vertical support middle part, vehicle frame 11 both sides is provided with left and right guide rail 7, lifting pedestal 12 both sides are fixed left and right guide wheel assembly 2 respectively, left and right guide wheel assembly 2 is located in the left and right guide rail 7, be located in the left and right guide rail 7 by left and right guide wheel assembly 2, guarantee that the lifting pedestal does not produce deflection when lifting; This embodiment also comprises hydraulic jack 1, left and right lifting chain 8, sprocket wheel beam 3 and is arranged on the left and right movable sprocket wheel 4 of sprocket wheel beam 3, and frame 11 is provided with crossbeam 5, and hydraulic jack 1 rises and can adopt handle to regulate or pin is stepped on multiple modes such as adjusting.Hydraulic jack 1 is fixed in the middle of the bottom girder 6 of vehicle frame 11, and hydraulic jack 1 top is fixedly connected on the middle part of sprocket wheel beam 3, and left and right lifting chain 8 one ends are fixed on the crossbeam 5, and by left and right movable sprocket wheel 4, the other end is fixed on the lifting pedestal 12 respectively.Circuit breaker cart is placed on the lifting pedestal 12, adopting hydraulic jack 1 to drive on the sprocket wheel beam moves, realize the lifting and the decline of lifting pedestal 12 by promoting chain 8, realize the position of transporting and rise to the required installation of switch cubicle from ground of circuit breaker cart, or circuit breaker transports from switch cubicle.
