Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locomotive parking auxiliary equipment, in particular to a locomotive iron shoe. Background Art
[0002] Iron shoes are an important measure to ensure the safety of the locomotive when it is stopped. Iron shoe braking is based on the principle that after the wheels on one or two rails are braked by iron shoes, sliding friction along the rail surface replaces the original wheel rolling friction. The strong friction generated after the wheels press on the iron shoes gives resistance to the vehicle, causing the vehicle to quickly lose its original speed and reach the purpose of stopping after a certain sliding distance. If the locomotive is stopped and the iron shoes are not used to quickly prevent slipping, it may cause the locomotive to slip and cause a safety accident. In order to prevent accidents, iron shoes can be used with the vehicle.
[0003] When the inner-line locomotive uses iron shoes in a stopped state, the iron shoes are often placed randomly in various places on the line or in various places in the West District Maintenance Depot. They are not returned to their original positions in time after use, and they need to be found and moved back and forth when they are used again. And because the iron shoes are placed randomly, people walking in this area are prone to tripping and posing a safety hazard. If an anti-slip device is required, the iron shoes cannot be quickly fastened, which can easily cause the locomotive to slip and cause a safety accident. The existing iron shoes only rely on the friction between the counterweight and the rail. After the iron shoes are used for a long time, the surface of the counterweight will easily become smooth, affecting the braking effect of the iron shoes and having a poor anti-slip effect.
[0004] Therefore, it is urgent to design a locomotive iron shoe to solve the problem that the existing locomotive iron shoe cannot be placed on the vehicle and is easy to find when used, and the iron shoe will cause poor anti-slip effect when used for a long time. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1:
[0023] like Figure 1-Figure 2 As shown, a locomotive iron shoe comprises an iron shoe 1 and an iron shoe placement mechanism 2. The iron shoe 1 is placed on the iron shoe placement mechanism 2. The iron shoe placement mechanism 2 comprises an upper hanging ring 2.1, a lower hanging ring 2.2, a buffer spring 2.3, a chain 2.4 and a hook 2.5. The inner side of the lower hanging ring 2.2 is fixedly mounted on the locomotive frame guard plate 4. A plurality of buffer springs 2.3 are connected between the lower hanging ring 2.2 and the upper hanging ring 2.1. The iron shoe 1 is inserted into the upper hanging ring 2.1 and the lower hanging ring 2.2. The counterweight 1.2 of the iron shoe 1 is blocked at the upper part of the upper hanging ring 2.1.
[0024] The lower hanging ring 2.2 and the upper hanging ring 2.1 are square metal rings adapted to the width of the stop iron 1.1. The inner side of the lower hanging ring 2.2 is welded to the locomotive frame guard plate 4. The upper part of the lower hanging ring 2.2 is connected to the upper hanging ring 2.1 through a buffer spring 2.3, and the upper hanging ring 2.1 is not fixed around. The locomotive wheel axle 3 is arranged inside the locomotive frame guard plate 4, and the locomotive wheel is installed on the locomotive wheel axle 3.
[0025] The iron shoe 1 comprises an iron stop 1.1, a counterweight 1.2, an anti-sliding block 1.3, a handle 1.4 and a chain mounting plate 1.5. The front part of the iron stop 1.1 is an inclined shovel-shaped structure. The iron stop 1.1 is plugged under the locomotive wheel of the locomotive. The middle and rear part of the iron stop 1.1 is provided with a counterweight 1.2.
[0026] The rear of the stop iron 1.1 is provided with an anti-slip block 1.3, which is a downwardly curved rubber block in close contact with the rail. The anti-slip block 1.3 provides the iron shoe with a second level of anti-slip protection, thereby preventing the iron shoe 1 from slipping due to the smooth contact surface between the counterweight block 1.2 and the rail, and providing higher safety.
[0027] A handle 1.4 is installed at the rear of the counterweight 1.2, and the upper part of the handle 1.4 is fixedly connected to a chain mounting plate 1.5, and the other side of the chain mounting plate 1.5 is fixed to the counterweight 1.2. The chain mounting plate 1.5 is provided with a mounting hole, and one end of a chain 2.4 is mounted on the mounting hole.
[0028] The other end of the chain 2.4 is connected to a hook 2.5, and the hook 2.5 is mounted on a motorcycle frame guard plate 4.
[0029] Embodiment 2: The working principle of the locomotive iron shoe using the structural form of embodiment 1.
[0030] An upper hanging ring 2.1 and a lower hanging ring 2.2 are made, and a concave iron is gripped with an iron plate. A buffer spring 2.3 is welded between the upper hanging ring 2.1 and the lower hanging ring 2.2. The lower hanging ring 2.2 is fixed on the locomotive frame guard plate 4 at the driving wheel of the inner line locomotive. An iron shoe 1 is placed according to the actual situation of the locomotive on site, and two hooks are welded with an iron plate (one is the hook 2.5 on the locomotive frame guard plate 4, and the other is the chain mounting plate 1.5 on the iron shoe 1). An iron chain is used near the frame to firmly connect the iron shoe 1 to the car body. When not in use, the iron shoe 1 is placed on the frame for fixing. The chain prevents the iron shoe from being taken away and placed at will when it is along the wheel or not in use, so as to ensure that each locomotive is equipped with two iron shoes to ensure the wheel stopping measures when the locomotive is braked.
