Abstract

The invention provides a method adjusting the height of hook of the railway truck. The method adjusting the height of the hook of the railway truck of the invention is that: 1. the core disc consuming discs with different bottom surface heights are made, which present basin-shaped structures; the center of the bottom surface is opened with a round hole; the bottom surface height of the consuming disc has the change range ranging from 5 mm to 40 mm; the bottom surface thickness of the consuming disc is made every 2 mm through 5 mm; 2. one or more consuming discs are selected to be padded between an upper core disc and a lower core disc; the external surface of the side wall of the consuming disc and the bottom surface external surface are matched with the internal surface of the lower core disc; the internal surface of the side wall and the internal surface of the bottom surface are matched with the external surface of the upper core disc; a central pin is inserted into a positioning hole of the upper core disc and the lower core disc for positioning connection. The invention adopts the consuming disc to adjust the height of the hook of the truck, designs the lower core disc and the steering frame bolster into a whole, and ensures the driving safety; the invention has simple and convenient and easy operation, reduces the parts of the steering frames and reduces the application cost.

Description

A kind of method of adjusting height of railway freight-car coupler

Technical field

The present invention relates to a kind of method of adjusting height of railway freight-car coupler.

Background technology

In order to guarantee the extension that can interconnect mutually between the railway truck, the freight car coupler height must be controlled in certain scope.Yet along with the prolongation of lorry operate time, because the abrasion of wheel track and other friction pairs, the hitch height can not meet the demands, and at this moment must adjust the freight car coupler height.The structure of existing railway truck vehicle frame is connected with truck center plate control apparatus 3 between bogie truck 1 and the car body 2 as shown in Figure 1, and hitch 4 is installed in the front end of car body 2.At present, to the method for freight car coupler 4 height adjustments as shown in Figure 2, mainly be to realize by the steel or the bamboo matter backing plate 7 that install different-thickness at truck center plate 5 and 6 of truck bolsters additional, connect by bolt 8 between truck center plate 5 and the truck bolster 6, by the knock hole of center pin 10 insertion truck center plates 5 and body center plate 9, cartridge 5 and body center plate 9 are located by connecting.The shortcoming of this method is to cause becoming flexible, fractureing of tie bolt 8 between truck center plate 5 and the truck bolster 6 easily, jeopardizes traffic safety; Installing additional, bolt 8 must being removed when changing backing plate 7, make troubles to maintenance.

Summary of the invention

At the deficiency of existing freight car coupler height adjustment technology, the invention provides a kind of easy to adjust, method of guaranteeing the adjustment height of railway freight-car coupler of traffic safety.

The present invention is achieved by the following technical solutions:

The method of adjustment height of railway freight-car coupler of the present invention is:

(1) the cartridge abrasion dish of a series of different bottom thickness of making, cartridge abrasion dish is the peviform structure, has a circular hole in bottom center, and the bottom thickness variation range of abrasion dish is 5mm～40mm, sidewall thickness remains unchanged, and the bottom thickness of abrasion dish is made one every 2～5mm;

(2) carry out the hitch height adjustment, the hitch height of Tiao Zhenging as required, select one or more abrasion plate mats between body center plate and truck center plate, the sidewall outside face of abrasion dish and bottom surface outside face cooperate with the truck center plate inside face, side wall inner surfaces and bottom surface inside face cooperate with the body center plate outside face, insert center pin and position connection in the knock hole of upper and lower cartridge.

The present invention adopts abrasion to coil and adjusts the freight car coupler height, compare with existing method and to have the following advantages: (1) can be designed to one-piece construction with truck center plate and truck bolster, no longer adopt bolted connection between the two, so just avoided because bolt looseness, the safety problem that driving brings to lorry fractures.(2) when changing the abrasion dish of different-thickness, truck body need only be lifted and need not dismantle the cartridge bolt, easy row simple to operation.(3) after the abrasion of employing cartridge are coiled and adjusted the hitch height, no longer need original cartridge backing plate, reduced the bogie truck parts, reduced use cost.

The specific embodiment

Embodiment

Fig. 3 has provided the method scheme drawing of adjustment height of railway freight-car coupler of the present invention.At first make the cartridge abrasion dish 11 of a series of different bottom thickness.The structure of cartridge abrasion dish 11 is the peviform structure as shown in Figure 4, has a circular hole in bottom center.The abrasion dish of different bottom thickness is meant: just change the thickness that wears away the face of trying to get to the heart of a matter, its variation in thickness scope is 5mm～40mm, and sidewall thickness remains unchanged.In the series abrasion dish, its bottom thickness is made one every 2～5mm.Abrasion dish 11 adopts the high-abrasive material compacting to form, and has resistance to abrasion and electric conductivity.

When carrying out the hitch height adjustment, the hitch height of Tiao Zhenging selects one or more abrasion plate mats between truck center plate 5 and body center plate 9 (referring to Fig. 3) as required, makes the try to get to the heart of a matter gross thickness of face of each abrasion equal the hitch height that will adjust.The sidewall outside face of abrasion dish 11 and bottom surface outside face cooperate with the inside face of truck center plate 5, and side wall inner surfaces and bottom surface inside face cooperate with the outside face of body center plate 9, insert center pin 10 and position connection in the knock hole of upper and lower cartridge.

The present invention is coiled by the abrasion of installing different-thickness series between body center plate and truck center plate additional and is reached the purpose of adjusting the freight car coupler height.When newly making lorry, install thin abrasion between upper and lower cartridge additional and coil and guarantee the freight car coupler height; When maintenance secondhand goods car, install thicker abrasion between upper and lower cartridge additional and coil and guarantee the freight car coupler height.

The present invention adopts between upper and lower cartridge pad abrasion dish 11 to adjust the freight car coupler height, and has the method that installs backing plate 7 additional 6 of truck center plate 5 and truck bolsters now and compares and have the following advantages:

(1) truck center plate 5 and truck bolster 6 can be designed to one-piece construction, and no longer adopt bolt 8 to connect.So just avoided because the safety problem that driving brings to lorry of becoming flexible, fracture of bolt 8.

(2) coiled 11 o'clock in the abrasion of changing different-thickness, truck body 2 need only be lifted and need not demounting bolt 8, easy row simple to operation.

(3) after employing abrasion dish 11 is adjusted the hitch height, no longer need original backing plate 7, make the bogie truck parts reduce, can reduce use cost.

Claims (1)

1. method of adjusting height of railway freight-car coupler, it is characterized in that: this method is:

(1) the cartridge abrasion dish of a series of different bottom thickness of making, cartridge abrasion dish is the peviform structure, has a circular hole in bottom center, and the bottom thickness variation range of abrasion dish is 5mm～40mm, sidewall thickness remains unchanged, and the bottom thickness of abrasion dish is made one every 2～5mm;

(2) carry out the hitch height adjustment, the hitch height of Tiao Zhenging as required, select one or more abrasion plate mats between body center plate and truck center plate, the sidewall outside face of abrasion dish and bottom surface outside face cooperate with the truck center plate inside face, side wall inner surfaces and bottom surface inside face cooperate with the body center plate outside face, insert center pin and position connection in the knock hole of upper and lower cartridge.
