Abstract
The invention relates to a coupling, in particular to a railway vehicle rescue coupling, which is of a box-shaped structure, and solves the problem of inconvenience in carrying and mounting on site of a rescue coupling. The railway vehicle rescue coupling made of high-strength weathering steel comprises a coupling head, a coupling body and a coupling tail, the coupling is integrally in a hollow box shape, reinforcing vertical ribs or stiffening plates are added at a coupling knuckle of the coupling head and a tail pin hole of the coupling tail, the coupling head can be hooked with a 13 type coupling and a 17 type coupling, and the coupling tail can enter a rotating sleeve of a 16 type coupling. The railway vehicle rescue coupling is light in weight and convenient for on-site carrying and mounting as the weight of the coupling is about one quarter of that (240kg) of the 17 type coupling, and is high in strength due to the fact that the coupling is integrally of a box-shaped structure and made of high-strength structural steel, strength of portions subject to large stress are locally enhanced, and the minimum failure load of the coupling is about one thirty-fifth of that (3430kN) of the 17 type coupling.
Description
Technical field
The present invention relates to a kind of hitch, be specifically related to a kind of rolling stock rescue hitch.
Background technology
At present, China 80t level or 70t level railway truck use 16,17 type hitches and draw bar to connect.When vehicle hitch et out of order, need carry out loopback with breakdown locomotive.In the vehicle rescue process in the past, need to join extension, and 16,17 type hitch weight are about 240kg, onsite moving and very inconvenience of installation with 16,17 type hitches and locomotive.
Summary of the invention
The present invention has solved the problem of rescue hitch onsite moving and inconvenient installation through adopting a kind of hitch of box-structure.
The present invention is realized by following technical scheme:
A kind of rolling stock rescue hitch; By the gib head part; Hook body and hook portion are formed, and integral body is interior empty van type, and the hook tongue place of gib head part and the pin hole place of hook portion are provided with and strengthen stud or stiffening plate; The gib head partial shape can join with 13,17 type hitches to be hung, and hook portion shape and structure can get into 16 type hitch turning sets.
It is high-strength weathering steel that the present invention rescues the hitch material.
It is in light weight that the present invention rescues hitch, and weight is about 1/4 of 17 type hitch weight (240kg), is convenient to onsite moving and installation; Intensity is high simultaneously, and integral body is box type construction, adopts the high-tensile structural steel manufacturing, strengthens than large part is local stressed, and minimize destruction load is about about 1/35 of 17 type hitch minimize destruction load (3430kN).
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; The present invention is by gib head part 1, and hook body 2 is formed with hook portion 3, and integral body is to form box by the high-strength weathering steel assembly welding; The hook tongue place of gib head part 1 is provided with and strengthens stud or stiffening plate 4; The pin hole place of hook portion 3 also is provided with and strengthens stud or stiffening plate 5, and the gib head partial shape can join with locomotive coupler to be hung, and hook portion shape and structure can get into 16 type hitch turning sets.
The present invention rescues hitch material yield intensity and is not less than 450MPa, and weight is 65kg, minimize destruction load: 100kN, traction highest running speed: 50km/h, maximum towing vehicle quantity: 30 of 9 of 80t level lorry loaded vehicle or empty wagons.
The concrete occupation mode of the present invention is following:
16,17 type hitches that existing car traction end is damaged or draw bar are removed the back and are installed to be somebody's turn to do by following requirements and rescue hitch:
1, removes former hitch
When traction end is the fixed end of 17 type hitches or draw bar, open draft key supporting plate bolt, the draft key supporting plate is taken off, take out draft key, former hitch is taken out.
When traction end is the round end of 16 type hitches or draw bar, open draft key supporting plate bolt, take off the draft key supporting plate, take out the draft key holder, with hitch or draw bar Rotate 180 °, take out draft key, former hitch is taken out.
2, the rescue hitch is installed
When traction end is the fixed end of 17 type hitches or draw bar, will rescue hitch and insert from the striker place, insert draft key, hold-down hook end pin supporting plate and bolt.
When traction end is the round end of 16 type hitches or draw bar, will rescue hitch and insert from the striker place, insert draft key (need not rotate the rescue hitch), the draft key holder of packing into, hold-down hook end pin supporting plate and bolt.
3, join to worry and draw
The hauling engine hitch leaves to the standard-sized sheet position, carries out contraposition and joins extension.
Should try traction after joining extension, check that each position can be by the relevant requirements running under power after normal.
This rescue hitch can satisfy the requirement of speedily carrying out rescue work of 80t level or 70t level railway truck, is applicable to substitute behind 16,17 type hitches and the draw bar to hang with the couplet of locomotive in the vehicle loopback process.
Claims (2)
1. a rolling stock is rescued hitch; By the gib head part; Hook body and hook portion are formed, and it is characterized in that: hitch is whole to be interior empty van type, and the hook tongue place of gib head part and the pin hole place of hook portion are provided with and strengthen stud or stiffening plate; The gib head partial shape can join with locomotive coupler to be hung, and hook portion shape and structure can get into 16 type hitch turning sets.
2. a kind of rolling stock rescue hitch according to claim 1, it is characterized in that: this hitch material is a high-strength weathering steel.
