Abstract
The utility model discloses a support device for an aluminium alloy cantilever, comprising a supporting tube (1) and double-lug sleeves (2), wherein the double-lug sleeves (2) are connected and fixed on two ends of the supporting tube (1) by screw threads; two ends of the supporting tube (1) are provided with external screw threads; the inner bores of the double-lug sleeves (2) are provided with internal screw threads; and the double-lug sleeves (2) are sheathed on two ends of the supporting tube (1) by the matching of the internal screw threads and the external screw threads. Compared with the prior art, the support device has the advantages that the main body of the supporting tube is connected with the double-lug sleeves (2) by the screw threads, and thus the defect that the top-thread support device for an aluminium alloy cantilever needs to be repeatedly examined is overcome. The support device for the aluminium alloy cantilever has simple structure, the safety, stability and the reliability of connecting parts are improved, the adaptability with the other parts of the aluminium alloy cantilever positioning system is improved, and the use requirement of a high-speed electrified railway can be satisfied.
Description
Technical field
The utility model relates to a kind of Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement, belongs to high-speed electric railway Catenary Fittings manufacturing technology field.
Background technology
The high-speed electric railway contact system adopts the Aluminium alloy arm for electric railway contact net as supporting part position fixing system in a large number, support tube is as the strength member that bracket system and position fixing system wherein are installed, need be suitable from aspect such as material, performance, interface mode and other parts of Aluminium alloy arm for electric railway contact net as supporting part position fixing system.The bracket bracing or strutting arrangement that generally uses on the circuit has steel support tube and jackscrew type Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement at present, steel support tube and aluminum alloy oblique wrist and arm can't be adaptive, though jackscrew type Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement is installed and used simply, but be subjected to aluminium-alloy pipe material, technology and puller bolt structural limitations, need check, confirm the reliability that puller bolt is locking repeatedly, safety and reliability are relatively low.
Summary of the invention
The technical matters that the utility model solves: design a kind of Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement, its support tube and ears sleeve are by being threaded, not only simple in structure, and the safety of part bonded assembly, stability and reliability have been improved, and with the suitability of other parts of Aluminium alloy arm for electric railway contact net as supporting part position fixing system, satisfied the operating needs of high-speed electric railway.
Technical solution of the present utility model: a kind of Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement, comprise support tube (1), ears sleeve (2), the two ends of described support tube (1) are fixed with ears sleeve (2) by being threaded.
The two ends of described support tube (1) are shaped on outside thread, and the endoporus of ears sleeve (2) is shaped on negative thread, and ears sleeve (2) is contained in the two ends of support tube (1) by the internal and external threads engage sleeves.
Be shaped on leaking hole (5) on the described ears sleeve (2).
Be equipped with pin (3) and spring cotter (4) on the described ears sleeve (2).
The utility model compared with prior art support tube body is connected by screw thread with the ears sleeve, overcome jackscrew type Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement and needed the drawback of inspection repeatedly, not only simple in structure, and the safety of part bonded assembly, stability and reliability have been improved, and with the suitability of other parts of Aluminium alloy arm for electric railway contact net as supporting part position fixing system, satisfied the operating needs of high-speed electric railway.

Fig. 3 is the structure cutaway view of the utility model ears sleeve.
The specific embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of Aluminium alloy arm for electric railway contact net as supporting part bracing or strutting arrangement comprises support tube 1, ears sleeve 2, and the two ends of described support tube 1 are shaped on outside thread, and the endoporus of ears sleeve 2 is shaped on negative thread, and ears sleeve 2 is contained in the two ends of support tube 1 by the internal and external threads engage sleeves.And be shaped on leaking hole 5 on the ears sleeve 2, be equipped with pin 3 and spring cotter 4.Be connected with bracket system or position fixing system with spring cotter 4 by pin 3.
Wherein support tube 1 adopts aluminium alloy extruded moulding and carries out heat treatment reinforcement, two ends mechanism outside thread.Ears sleeve 2 adopts cast aluminium alloy material and precision casting process moulding and carries out heat treatment reinforcement, endoporus mechanism negative thread.Pin 3 is an aluminum alloy materials, and heat treatment reinforcement.
Generally finish the processing and the assembly of support tube 1, ears sleeve 2, pin 3 and spring cotter 4 in factory.Only need take out spring cotter during use and the ears sleeve is connected with bracket system or position fixing system, penetrate spring cotter again and bending gets final product, install simple and convenient by pin.
