Abstract

The invention discloses a connection device of a locomotive cowcatcher. A front end plate (1) of the locomotive is provided with a fixed plate (2); both the fixed plate (2) and a loose piece (3) have a surface which is processed into a surface with a zigzag section; the fixed plate (2) and the loose piece (3) have the same zigzag shape; a bolt (4) passes through a gasket (7), a cowcatcher (5), the front end plate (1), the fixed plate (2) and the loose piece (3); the other end of the bolt is fastened by double nuts (6); and the saw teeth of the zigzag surfaces of the fixed plate (2) and the loose piece (3) are meshed. By adopting the connection device disclosed by the invention, the connection between the cowcatcher and the front end plate of the locomotive is more reliable, the bolt fastening operation is more standard, and the height of the cowcatcher is easier to adjust.

Description

The connecting device of cowcatcher
Technical field:
The present invention relates to a kind of connecting device of cowcatcher.
Background technology:
Pilot is the vitals of locomotive safety running, and its mounting structure should be solid and reliable, during maintenance, also should be able to carry out height adjustment according to the locomotive needs.
The installation of the pilot of tradition shunting locomotive; The main bolt that relies on is fastened on pilot on the locomotive front end-plate is; Whole pilot weight is all born by the friction force between front end-plate and two planes of pilot, though simple in structure, higher to the intensity and the fastening operation requirements of bolt.When fastening, be not carry out according to the Tightening moment that bolt is usually set fastening, but with bolt be tightened onto can not rotate till, such operation is bigger to the infringement of bolt, simultaneously, the degree of screwing of each bolt is also different.In when adjustment maintenance, operating personal need observe that the distance of pilot both sides and rail level is whether consistent confirms its whether level, therefore, and to the adjustment ten minutes inconvenience of pilot.And, determined by this force way, if the vibrations in fastening misoperation or the utilization process cause bolted bad, even the dangerous situation of pilot landing when locomotive operation can appear.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, provide that a kind of that cowcatcher is connected with the locomotive front end-plate is more reliable, the connecting device that the maintenance adjustment is more convenient.
Technical scheme of the present invention is: a kind of connecting device of cowcatcher; Locomotive front end-plate and pilot bonded assembly fixed orifice place welding adapter plate, it is zigzag surface that adapter plate and loose piece all are provided with a cross section, each sawtooth cross section can be a triangle; Also can be trapezoidal; Bolt passes packing ring, pilot, front end cover, adapter plate and loose piece, and the other end of bolt is fastening with double nuts, the engagement of the serrated-surface of adapter plate and loose piece.
Use this kind connecting device benefit to be: at first; Rely on the engagement between the gullet plate to carry pilot weight; Improved the force structure that original design only relies on locomotive front end-plate and pilot two planar friction power to carry, made pilot more reliable with being connected of locomotive front end-plate.Secondly, it is control gullet plate engagement distance that bolt mainly acts on, and the standard Tightening moment of bolt just can satisfy fastening requirement, makes the fastening operation of bolt standard more.At last, when the maintenance adjustment, bolt is moved up and down in the strip hole of front end-plate and adapter plate through the engage position of adjusting loose piece and adapter plate sawtooth up and down; The drive pilot moves up and down; Be easy to adjust the height of pilot, and keep the level of pilot, easy to operate.
Description of drawings:
Fig. 1 is the front view of the connecting device of cowcatcher of the present invention.
Fig. 2 is along A-A line cutaway view Amplified image among Fig. 1.
Fig. 3 is the enlarged drawing of front view of the connecting device adapter plate of cowcatcher of the present invention.
Fig. 4 is the enlarged drawing of front view of the connecting device loose piece of cowcatcher of the present invention.
Fig. 5 is the connecting device adapter plate of cowcatcher of the present invention and the sawtooth enlarged drawing of loose piece.
The specific embodiment:
Do further description below in conjunction with the accompanying drawing specific embodiments of the invention.
As depicted in figs. 1 and 2; Structural representation for the connecting device of cowcatcher of the present invention; Locomotive front end-plate 1 and pilot 5 bonded assembly fixed orifice places welding adapter plate 2 (as shown in Figure 3) all are processed with rectangular through hole on adapter plate 2 and the front end-plate 1, and it is zigzag surface that adapter plate 2 has a face to be processed to the cross section; It is zigzag surface that loose piece 3 (as shown in Figure 4) also has a surface to be processed to the cross section; Adapter plate 2 is identical with loose piece 3 zigzag fashions, can be equilateral triangle (as shown in Figure 5), also can be isosceles trapezoid.Bolt 4 passes packing ring 7, pilot 5, front end-plate 1, adapter plate 2 and loose piece 3, and the other end of bolt is fastened on the loose piece 3 with double nuts 6, uses that two nuts 6 are fastening can be used for preventing nut loosening.The engagement of the serrated-surface of adapter plate 2 and loose piece 3.
Rely on the engagement between the gullet plate to carry pilot weight, improved the force structure that original design only relies on front end-plate and pilot two planar friction power to carry, make pilot more reliable with being connected of locomotive front end-plate.Secondly, it is control gullet plate engagement distance that bolt mainly acts on, and the standard Tightening moment of bolt just can satisfy fastening requirement, makes the fastening operation of bolt standard more.At last, when the maintenance adjustment, bolt is moved up and down in the strip hole of front end-plate and adapter plate through the engage position of adjusting loose piece and adapter plate sawtooth up and down; The drive pilot moves up and down; Be easy to adjust the height of pilot, and keep the level of pilot, easy to operate.
What should explain at last is: though abovely described the specific embodiment of the present invention; But those skilled in the art are to be understood that; These only are casehistorys; Can make numerous variations or modification to these specific embodiment, and not deviate from principle of the present invention and essence, protection scope of the present invention is defined by the claims.
