Description

Technical Field

[0001] The utility model relates to the technical field of track maintenance, in particular to a stable running wheel of an MP12 profiling grinder. Background Art

[0002] The repair work of turnout rail surface requires the repair of rail welds, fat edges, fish scales, and the repair of frogs and pointed base rail profiles. If the bulky MV3 rail grinder is used, at least two transport vehicles and corresponding operators are required to transport the grinding equipment to meet the work needs. The improvement and invention of the "MP12 profiling grinder stable running wheel" saves loading space. An Iveco tool car can carry a variety of grinding equipment, improving the modular grinding efficiency of turnout rail surface repair. Each work team saves a transport vehicle, 4 laborers and 1 car driver. Utility Model Content

[0003] The purpose of the utility model is to provide a stable running wheel for an MP12 profiling grinder, so that the MP12 profiling grinder, which only has the ability to grind rail weld joints, can also have the ability to grind rail fat edges, fish scales and repair profiles, so that old equipment can have new uses, and can replace the expensive MV3 rail fine grinder in rail surface repair work, saving more than 100,000 yuan in equipment procurement costs per unit.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A MP12 profiling grinder stable running wheel, consisting of a fixed frame, a connecting rod and an insulating wheel;

[0006] The fixing frame is composed of a lower crossbar connector of the grinder, a connecting rod sleeve and a positioning pin. The upper connector of the lower crossbar connector of the grinder is fixedly arranged at the lower end of the connecting rod sleeve, and the positioning pin is located in a threaded hole through which the upper end of the connecting rod sleeve is provided.

[0007] The connecting rod comprises an angled end and a long straight end, the angled end of the connecting rod is inserted into the connecting sleeve and fixed by the positioning pin, and a nut is welded to the long straight end of the connecting rod;

[0008] A threaded rod is built into the center of the insulating wheel, which is screwed into a nut at the end of the connecting rod and fixedly connected to the connecting rod.

[0009] Furthermore, the connecting rod sleeve has an elevation angle of 25° and a length of 90 mm.

[0010] Furthermore, the connecting rod is a hollow steel pipe with a total length of 1140 mm, a fold angle of 25°, an outer diameter of 20 mm, and an inner diameter of 16 mm, and the inner diameter of the nut is 16 mm.

[0011] Furthermore, the insulating wheel is a nylon insulating wheel with an outer diameter of 100 mm and a built-in threaded rod with a diameter of 16 mm.

[0012] Beneficial effects of the utility model:

[0013] 1. Stable support function: When in use, after the stable running wheel of the MP12 profiling grinder is installed and fixed, the insulating wheel is placed on the other rail to play a stable support role. The operator does not need to rely on manpower to support the grinder, saving physical strength for the operator;

[0014] 2. Smooth grinding function: With the support of stable running wheels, operators can drive the machine to move smoothly on the rail surface to be polished, making the polished light strip straight and smooth;

[0015] 3. Profile repair function: The MP12 profiling grinder can be used to perform preventive and repair grinding on the rail profile through the angle adjustment device, so as to replace the MV3 rail fine grinder to repair the rail profile and delay or remove fish scale damage;

[0016] 4. Fat edge grinding function: When the MP12 profile grinder is adjusted to 0°, the stable running wheel can stably support the grinder to grind and remove the fat edge of the rail. On the one hand, it replaces the fat edge grinding function of the MC3 turnout fine grinder, and on the other hand, it saves the operator's physical strength to support the grinder with his body;

[0017] 5. Solved the difficulty of vehicle transportation: Originally, one Iveco tool truck could only carry one MV3 rail grinding machine, and other equipment such as generators, turnout fat edge grinders, and profiling grinders could not be transported together; the improved invention of the "MP12 profiling grinder stable running wheel" has given new uses to old equipment, and one machine has multiple uses, so that one Iveco tool truck can carry multiple grinders, generators, angle grinders, flatbed trucks, etc., so that the work team can carry the corresponding grinding machines modularly according to the needs of the operation, thereby improving the grinding coverage and work efficiency.
