Description

Technical Field

[0001] The utility model relates to the technical field of internal combustion engine maintenance tools, and particularly relates to a locomotive inspection hammer with replaceable hammer heads. Background Technique

[0002] In the maintenance work of diesel locomotives, maintenance personnel usually use a tool called an inspection hammer for detailed inspections. This inspection mainly focuses on whether bolts, nuts or other connectors are loose, because any slight looseness may pose serious safety hazards during the operation of diesel locomotives.

[0003] For the inspection hammer, its hammer head is generally made of metal materials. This metal-made hammer head can indeed meet the basic inspection requirements in most cases. However, when facing the components in the locomotive with complex structures and different materials, this metal hammer head seems a bit inadequate. Especially when inspecting those relatively fragile components, if the metal hammer head is still used for knocking, it is very likely that these components will be damaged due to improper control of the force, and even affect the normal operation of the entire locomotive.

[0004] In terms of structure, most of the existing inspection hammers have an integrated design for their hammer heads. Although this design enhances the overall strength of the hammer head to a certain extent, it also brings some disadvantages. Once the flat head part or the pointed head part of the hammer head is damaged due to long-term use or accidental impact, it is often impossible to replace the damaged part alone, but the entire hammer head needs to be replaced. This not only increases the maintenance cost but also reduces the use efficiency of the inspection hammer. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems raised in the above background technique, and then propose a locomotive inspection hammer with replaceable hammer heads.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

Two non-magnetic bodies are symmetrically arranged on both sides of the permanent magnet, and the two non-magnetic bodies are located between the two magnetic guiding seats to separate the two magnetic guiding seats.

[0011] Further, a first blind hole and a second blind hole are symmetrically arranged on the magnetic guiding seat. The first blind hole corresponds to the first guiding hole and is inserted with the first magnetic guiding rod, and the second blind hole corresponds to the second guiding hole and is inserted with the second magnetic guiding rod.

[0012] Further, a convex seat is formed at the front end of the connecting seat, and the knob assembly is arranged on the convex seat and is connected to the magnetic force assembly.

[0013] Further, the knob assembly includes a guiding block, a rotating shaft, a knob and a positioning pin; the guiding block is placed in the concave cavity and is connected with the rotating shaft at the end. A positioning hole is arranged on the rotating shaft, and one end of the rotating shaft passes through a through hole arranged on the connecting seat and is connected with the knob outside the convex seat. The positioning pin passes through a jack arranged on the convex seat and is inserted into the positioning hole to position the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model can replace the flat head hammer or the pointed head hammer separately when needed, without replacing the whole hammer head, saving the maintenance cost.

[0016] 2. The utility model adsorbs and fixes the flat head hammer or the pointed head hammer through the magnetic force assembly.

[0026] For the above solution, specifically regarding the connection structure between the connection base 2 and the magnetic component 5:

[0027] Refer to the appendix Figure 4 As shown, an installation cavity 23 that communicates with both the first guide hole 21 and the second guide hole 22 is provided inside the connection base 2, and the magnetic component 5 is installed in the installation cavity 23.

[0028] For the above solution, specifically regarding the structure of the magnetic component 5:

[0029] Refer to the appendix Figure 3 and the appendix Figure 4 As shown, the magnetic component 5 includes a magnetic conduction base 51, a permanent magnet 52, and a non-magnetic conductor 53; there are two magnetic conduction bases 51 which are symmetrically arranged in the installation cavity 23, a cavity 511 is formed between the two magnetic conduction bases 51, the permanent magnet 52 is rotatably installed in the cavity 511, the permanent magnet 52 has N and S poles along the diameter direction, and a concave cavity 521 for accommodating the knob assembly 6 is provided at the end of the permanent magnet, two non-magnetic conductors 53 are symmetrically arranged on both sides of the permanent magnet 52, and the two non-magnetic conductors 53 are located between the two magnetic conduction bases 51 to separate the two magnetic conduction bases 51.

[0030] Among them, considering the positioning effect of the magnetic component 5 on the first magnetic conduction rod 31 and the second magnetic conduction rod 41, for this reason, refer to the appendix Figure 4 As shown, blind holes 512 and 513 are symmetrically arranged on the magnetic conduction base 51, the blind hole 512 corresponds to the first guide hole 21 and accesses the first magnetic conduction rod 31, and the blind hole 513 corresponds to the second guide hole 22 and accesses the second magnetic conduction rod 41.
