Description
Technical field
The utility model relates to a kind of bogie truck, relates in particular to a kind of bogie truck with multi-functional wheel shaft lifting appliance.
Background technology
In bogie truck assembling process and after completing when handling, need bogie truck possess axle system can with the function of framework integral lifting.Railway locomotive steering was for realizing this function in the past, backstop and hoisting function framing member are generally set directly over axle box, directly over backstop be set require the perforate of framework lower cover, this has not only weakened bogie rigidity, also raised the height of whole bogie truck simultaneously, so the height of whole locomotive.
Summary of the invention
The technical problems to be solved in the utility model is: the structure of existing bogie truck has not only weakened bogie rigidity, has also raised the height of whole bogie truck simultaneously, and even the height of whole locomotive, and a kind of bogie truck with multi-functional wheel shaft lifting appliance is provided.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical matters adopts: this bogie truck with multi-functional wheel shaft lifting appliance comprises lifting appliance and framework, lifting appliance is arranged on the lateral surface of truck journal box, described lifting appliance is " day " word structure, lifting appliance top is horizontal stop surface, both sides, lifting appliance top are respectively provided with a T shape hanger, the middle strut rail place of described lifting appliance is provided with vertical damper interface, lifting appliance is provided with the interface of 6 places for being connected with axle box, described framework is provided with suspension hook, the side of described framework is provided with side block.
The beneficial effects of the utility model are: this bogie truck with multi-functional wheel shaft lifting appliance simple in structure, avoid perforate on framework lower cover, and increase bogie rigidity, reduce the height of bogie truck, handling is convenient, saves time, and can improve the production efficiency of manufacture.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Figure 1A to structural representation;
Fig. 3 is local structural representation;
Wherein: 1, lifting appliance, 2, horizontal stop surface, 3, T shape hanger, 4, vertical damper interface, 5, interface, 6, truck journal box, 7, framework, 8, suspension hook, 9, side block.
Detailed description of the invention
As shown in figures 1 and 3, figure comprises lifting appliance 1 and framework 7, lifting appliance 1 is arranged on the lateral surface of truck journal box 6, described lifting appliance 1 is " day " word structure, lifting appliance 1 top is horizontal stop surface 2, lifting appliance 1 both sides, top are respectively provided with a T shape hanger 3, the middle strut rail place of described lifting appliance 1 is provided with vertical damper interface 4, lifting appliance 1 is provided with the interface 5 of 6 places for being connected with axle box, described framework 7 is provided with suspension hook 8, as shown in Figure 2, the side of framework 7 is provided with side block 9.
The feature of this bogie truck has:
(1) lifting appliance 1 possesses the function of bogie truck together with wheel shaft lifting.This lifting appliance 1 is arranged on truck journal box 6 lateral surfaces, is connected with wheel shaft.The T shape hanger 3 of this lifting appliance is used in conjunction with the suspension hook 8 on framework 7.When bogie truck is lifted, T shape hanger 3 contacts with suspension hook 8, with together slinging together with wheel shaft by lifting appliance, realizes the integral lifting of bogie truck.While lifting, between T shape hanger 3 and suspension hook 8, leave certain spacing, both made can not contact under normal operating condition, and ensure that pull bar can excessively not reverse in the time of lifting, primary spring can not thrown off with framework.
(2) lifting appliance 1 possesses the effect of wheel shaft to transverse force between framework of transmitting.The horizontal stop surface 2 of this lifting appliance is used in conjunction with the side block 9 of framework 7 sides.
(3) lifting appliance 1 is also for one is that vertical damper provides assembling vertical damper interface 4.
(4) avoid the perforate of framework lower cover, increased bogie rigidity.
(5) horizontal stop surface 2 and lifting appliance 1 are moved on to axle box side, framework 7 highly can more close axle box, thereby reduces the bottom-to-top-height of bogie truck.
This bogie truck with multi-functional wheel shaft lifting appliance simple in structure, has avoided perforate on framework lower cover, has increased bogie rigidity, has reduced the height of bogie truck, and handling is convenient, saves time, and can improve the production efficiency of manufacture.
