Abstract
The utility model relates to narrow-rail railway transportation traction equipment in the industries such as tunnel construction and mining, and particularly to a vibration damping device for an axle box of an industrial and mining electric locomotive. The vibration damping device for the axle box of the industrial and mining motor comprises two sets of rubber vibration-damping springs, which are in a reverse-V-shaped arrangement on the axle box. The two sets of rubber vibration-damping springs are jointed with an opening of a side plate of the locomotive body through a supporting seat. The opening of the side plate of the locomotive body is of an isosceles trapezoid shape. Furthermore an included angle beta between two equal waists and an included angle alpha between the two sets of rubber vibration-damping springs, and a supporting seat is square. The vibration damping device for an axle box of the industrial and mining electric locomotive has the following advantages: simple and reasonable structure of the axle box vibration-damping springs, shortened fabrication and assembling time, reduced cost and improved efficiency.
Description
Technical field
The utility model relates to the narrow gage railway transportation tractor equipment in the industries such as constructing tunnel and mining, specifically is that a kind of axle box damping spring adopts the fixing industrial-mineral electric locomotive of novel draw bail.
Background technology
The draw bail of existing industrial-mineral electric locomotive axle box damping spring as shown in Figure 1, two groups of rubber shock-absorbing springs 4 are down ' V ' font and arrange setting on axle box 2, car body side plate 1 opening becomes square frame shape structure, two groups of rubber shock-absorbing springs 4 are wedge shape by shape supporting seat 3 cooperates connection with the opening part of car body side plate 1, because the shape of supporting seat 3 is complicated, the general forging that adopts shapes then; Make that the work capacity of draw bail in making, assembling of axle box damping spring is big, cost is higher.
Summary of the invention
There are problems such as processed complex, cost height in the utility model in order to solve the existing industrial-mineral electric locomotive axle box damping spring structure that is connected and fixed, and a kind of industrial-mineral electric locomotive axle box shock absorption device is provided.
The utility model is to adopt following technical scheme to realize: industrial-mineral electric locomotive axle box shock absorption device, be included on the axle box and be down two groups of rubber shock-absorbing springs that setting arranged in ' V ' font, two groups of rubber shock-absorbing springs cooperate connection by supporting seat with the opening part of car body side plate, the car body side plate opening part is isosceles trapezoid, and its two waists angle β is identical with two groups of rubber shock-absorbing springs arrangement angulation α sizes, and supporting seat is square.
Compared with prior art, car body side plate opening part of the present utility model is isosceles trapezoidal structure, and is as broad as long when its processing technology and opening part are square frame shape, do not increase the difficulty of technology; Because the car body side plate opening part makes that to the employing of isosceles trapezoidal structure supporting seat is square, the supporting seat that is wedge shape with shape is compared, and is simple in structure, and easily processing adopts the complementary angle material of general steel plate to get final product, and can simplify technology greatly, with low cost.Axle box damping spring draw bail of the present utility model is simple, reasonable, can shorten manufacturing, built-up time, and cost-cutting is raised the efficiency.
Description of drawings
Fig. 1 is existing industrial-mineral electric locomotive axle box shock absorption device scheme drawing;
Fig. 2 is the utility model industrial-mineral electric locomotive axle box shock absorption device scheme drawing;
Among the figure: the 1-car body side plate; The 2-axle box; The 3-supporting seat; 4-rubber shock-absorbing spring.
The specific embodiment
The utility model industrial-mineral electric locomotive axle box shock absorption device, be included in and be down two groups of rubber shock-absorbing springs 4 that setting arranged in ' V ' font on the axle box 2, two groups of rubber shock-absorbing springs 4 cooperate connection by supporting seat 3 with the opening part of car body side plate 1, car body side plate 1 opening part is isosceles trapezoid, and its two waists angle β is identical with two groups of rubber shock-absorbing springs, 4 arrangement angulation α sizes, and supporting seat 3 is square.
