Problems solved by technology

When tightening, the bolts are not tightened according to the tightening torque usually set by the bolts, but the bolts are tightened until they cannot be rotated. Such an operation will cause great damage to the bolts. Same
During maintenance and adjustment, the operator needs to observe whether the distance between the two sides of the obstacle remover and the rail surface is consistent to determine whether it is level. Therefore, it is very inconvenient to adjust the obstacle remover
Moreover, due to this force-bearing method, if the fastening operation is improper or the vibration during operation causes the bolts to be fastened poorly, there may even be a dangerous situation where the obstacle remover will slip when the locomotive is running.

Embodiment Construction

[0012] The specific embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 with figure 2 As shown, it is a structural schematic diagram of the connecting device of the locomotive obstacle remover of the present invention, and the fixing hole where the front end plate 1 of the locomotive is connected with the obstacle remover 5 is welded with the fixing plate 2 (such as image 3 As shown), the fixed plate 2 and the front end plate 1 are all processed with long strip through holes, and the fixed plate 2 has a surface that is processed into a zigzag surface, and the movable block 3 (such as Figure 4 shown) also has a surface that is processed into a sawtooth-shaped surface, and the fixed plate 2 and the movable block 3 have the same sawtooth shape, which can be an equilateral triangle (such as Figure 5 shown), it can also be an isosceles trapezoid. The bolt 4 passes through the washer 7, t...

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

Technical field: [0001] The invention relates to a connection device of a locomotive obstacle remover. Background technique: [0002] The obstacle remover is an important part of the safe operation of the locomotive. Its installation structure should be firm and reliable. During maintenance, it should be able to adjust the height according to the needs of the locomotive. [0003] The installation of the obstacle remover of the traditional shunting locomotive mainly relies on bolts to fasten the obstacle remover to the front end plate of the locomotive. The weight of the entire obstacle remover is borne by the friction between the two planes of the front end plate and the obstacle remover. Although the structure is simple, it requires high bolt strength and fastening operation. When tightening, the bolts are not tightened according to the tightening torque usually set by the bolts, but the bolts are tightened until they cannot be rotated. Such an operation will cause great d...
