Abstract
The utility model belongs to train parts, particularly a brake shoe rock used for connecting a brake shoe and a brake shoe holder of trains. The brake shoe rock is composed of an occlusion member, the shape of which is provided with radian and the tail part of which is provided with taper, and a concealed member which is inserted in the occlusion member and is provided with corresponding radian, wherein the shape of the occlusion member and the radian of the occlusion member are matched with the radian of a brake shoe back, brake shoe nostril and a matched hole of the brake shoe holder so as to form a tight cooperation with the brake shoe and the brake shoe holder; the concealed member uses a metal member, and the occlusion member is made of macromolecular material. The brake shoe rock has the advantages of reasonable shape and structure, convenient installation, light weight, abrasion resistance and age resistance, bears strong impact force and repeated tension, lowers the labor intensity of maintenance work and reduces the cost of railway transportation.
Description
Technical field
The utility model belongs to the train parts, particularly a kind of brake shoe watt pricker that is used for the connection of train brake shoe.
Background technique
Brake shoe watt pricker is to be used for link that train brake shoe and brake shoe watt holder are connected with each other, because its Placement is socket connection, and its material is metallic material, so often owing to artificial factor is lost.And its wear resistance, shock resistance are also not ideal enough.
Summary of the invention
It is light, wear-resisting, anti-aging that the purpose of this utility model provides a kind of body, shape and brake shoe watt pricker rational in infrastructure.
According to brake shoe of the present utility model watt pricker, it is characterized in that this brake shoe watt pricker has radian and afterbody by profile and has containing part and inserting this hiding part with corresponding radian that contains in the middle of the part and form of tapering.
Describedly contain part profile and the radian that is had thereof and be complementary, form and the closely cooperating of brake shoe and watt holder with the matching hole of radian, brake shoe watt nostril and the brake shoe watt holder of the brake shoe watt back of the body.
It is to contain 50～70% of part total length that described hiding part inserts the degree of depth of containing part.
Described hiding part is the metalwork with sufficient intensity, contains part for having tensile strength 75～100MPa, and impact strength is 7～9.6MPa, flexural strength 140～170MPa, the macromolecular material of incompressible intensity 100～130MPa.
Because configuration design of the present utility model is reasonable, can securely the high strength of hiding part organically be combined with intensity and the toughness of containing part, the impact force of intensity and stretching repeatedly when making this brake shoe watt pricker bear equipment operation effectively, and have characteristics such as body is light, wear-resisting, anti-aging, help the normal operation of equipment and alleviate the workload that the workman changed or overhauled watt pricker.Owing to play a protective role to hiding part with containing part, can prevent losing of brake shoe watt pricker, not only improve the operating rate of equipment, and reduced cost.
Description of drawings
Fig. 1 is structural representation of the present utility model and user mode figure.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in the figure, brake shoe of the present utility model watt pricker is characterized in that this brake shoe watt pricker has radian and afterbody by profile and has containing part 2 and inserting these hiding parts 1 with corresponding radian that contain in the middle of the part 2 and form of tapering.
As shown in the figure, the described matching hole that contains radian, brake shoe watt nostril 5 and the brake shoe watt holder 3 of part 2 profiles and the radian that is had and the brake shoe watt back of the body is complementary, and forms with brake shoe 4 and reaches closely cooperating of watt holder 3.
It is to contain 50～70% of part 2 total lengths that described hiding part 1 inserts the degree of depth of containing part 2.
Described hiding part 1 contains part 2 for having tensile strength 75～100MPa for having the metalwork of sufficient intensity, and impact strength is 7～9.6MPa, flexural strength 140～170MPa, the macromolecular material of incompressible intensity 100～130MPa.
This brake shoe watt pricker shape and shape are rational in infrastructure, and body is light, wear-resisting, anti-aging, and is easy for installation, reduced maintenance work labor intensity, reduced cost of railway traffic.
