Abstract
The utility model relates to a steering frame traction device. The steering frame traction device comprises a traction centre pin, a traction center base, a traction rubber pile, an anti-overcharging stop catch and a lifting pad, and further comprises a lifting mat fixed below the lifting pad. The outer diameter of the lifting mat is greater than the spacing distance of the anti-overcharging stop catch. The maximum width of the traction centre base is smaller than the spacing distance of the anti-overcharging stop catch.. The anti-overcharging stop catch is arranged in a middle and lower position of an installation hole wall of the steering frame traction device. The lifting mat is matched with the anti-overcharging stop catch to lift. Based on the original structure and under the premise of not changing other parts interfaces of the steering frame, the structure is optimized so that the traction device can be assembled without reversing the steering frame so as to cancel the steps of reversely assembling the frame, thereby simplifying the assembling process, improving the production efficiency, and saving the production cost.
Description
Technical field
The utility model relates to a kind of bogie truck draw gear, belongs to the rail vehicle truck technical field.
Background technology
Metropolis series bogie truck has all adopted the draw gear of traction rubber metal pad formula, and this device is positioned at truck frame crossbeam center, can realize the anti-function that overcharges with integral lifting.Shown in Fig. 1-3, this device comprises centre of pull pin 1, centre of pull seat 2, anti-backstop 3, traction rubber metal pad 4, jigger mast 5, the jigger mast binding bolt 6 of overcharging, the anti-bolt 10 that overcharges.The centre of pull pin to car body, when car body lift by crane, drives centre of pull pin and centre of pull seat through bolted connection, finally overcharges the anti-backstop that overcharges on the bolt support bogie truck with whole bogie truck lifting by being installed in anti-on the centre of pull seat.As shown in Figure 2; Centre of pull seat 2 has two boss 11 to be used for installing the anti-bolt 10 that overcharges and since on the bogie truck two anti-ly overcharge backstop 3 and stop that the centre of pull seat can only be put into bogie pivot center from the below of bogie truck; And in producing at the scene; Because bad operation below bogie truck, the general upset tire that adopts is the bogie truck turned upside down, and (promptly be below bogie truck up) put into bogie pivot center with centre of pull seat 2 from top to bottom.It is thus clear that the bogie truck draw gear of this structure when bogie truck is assembled, must adopt framework upset tire framework to be placed antiposition, packaging technology more complicated, inefficiency.
Summary of the invention
The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, and a kind of bogie truck draw gear is provided; On the original structure basis, do not change under the prerequisite with other parts interfaces of bogie truck, structure is optimized; Draw gear can be assembled under the situation of nonreversible framework, thus cancellation framework antiposition assembling procedure, simplified assembling process; Enhance productivity, save production cost.
In order to solve above technical matters; The bogie truck draw gear that the utility model provides; Composition comprises: centre of pull pin, centre of pull seat, traction rubber metal pad, anti-backstop, the jigger mast of overcharging; It is characterized in that: also have the pad that hangs that is fixed in the jigger mast below, the said pad external diameter that hangs is greater than the anti-spacing distance that overcharges backstop, and the maximum width of said centre of pull seat is less than the anti-spacing distance that overcharges backstop; The said anti-backstop that overcharges is arranged at the middle upper/lower positions that the bogie truck draw gear is installed hole wall, saidly hangs pad and fills backstop and cooperates realization to lift by crane.
Further, hang pad and fix through lifting pad binding bolt and jigger mast, said hang the pad binding bolt from down and on be screwed into and hang pad and jigger mast, said hang the pad lower surface and hang to fill up between the binding bolt head upper surface be provided with adjusting pad.
Further, said jigger mast fastens as one through jigger mast binding bolt and centre of pull pin and centre of pull seat.
The installation method of this bogie truck draw gear may further comprise the steps:
The first step, from top to bottom the centre of pull seat is put into bogie truck draw gear mounting hole;
Second step, centre of pull pin are put into the centre of pull seat;
The 3rd step, from the below jigger mast is close to the lower surface of centre of pull seat;
The 4th goes on foot, with the jigger mast binding bolt jigger mast, centre of pull seat, centre of pull is locked and be solidly connected;
The 5th goes on foot, will hang from the below lower surface that pad is close to jigger mast;
The 6th the step, with hang the pad binding bolt will hang the pad and jigger mast be fastenedly connected.
Further, in the 6th step, at first on the double-screw bolt that hangs the pad binding bolt, overlap adjusting pad, and then install and hang the pad binding bolt.
The centre of pull seat is on the basis of prototype, to improve, and has removed the boss of original both sides, does not change with the interface of other parts.When car body lifts by crane; Drive centre of pull pin, centre of pull seat lift by crane together; And the lifting pad tightens together through lifting pad binding bolt and jigger mast; Jigger mast tightens together through jigger mast binding bolt and centre of pull pin and centre of pull seat again, finally by the anti-backstop that overcharges on the lifting advance expenditure support bogie truck with whole bogie truck lifting.Adjusting pad below the lifting pad can be used for adjusting the lifting pad and overcharges the gap between the backstop.
Through changing the position of backstop on centre of pull holder structure and the truck transom, make the centre of pull seat to put into the crossbeam center from the crossbeam top.This apparatus structure mentality of designing is simple, and convenient in application can improve production and assembly efficient, saves production cost, and can apply to the guideway vehicle field widely.
