Description

Technical Field

[0001] The utility model relates to the technical field of inspection hammers, and more specifically, to a magnetic inspection hammer for diesel locomotives. Background Art

[0002] In the maintenance process of diesel locomotives, the inspection work of ground crew is crucial, which is directly related to the overall safety performance and stable operation of the vehicle. Among them, the inspection hammer is a useful assistant in their hands, used to accurately check the tightening degree of bolts and the integrity of connecting parts.

[0003] However, in actual operation, when tightening bolts, it is often necessary to temporarily place the inspection hammer aside. Simply placing it on the ground not only makes it easy to forget to pick it up, but also inconvenient for subsequent operation and picking up, and it is more likely to be left on the locomotive during the busy process, which undoubtedly brings potential safety hazards to the operation of the locomotive.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:

[0022] Referring to the attached Figure 1 As shown, a magnetic adsorption type inspection hammer for a diesel locomotive includes a hammer handle 1, a hammer head 2, a connection component 3 and a magnet 4; wherein, one end of the hammer handle 1 is connected with the hammer head 2, and the other end of the hammer handle 1 is detachably connected with the magnet 4 through the connection component 3 so that the magnet 4 can be used to adsorb on the top or side of the diesel locomotive carriage.

[0023] By adding a magnet 4 to this device, the inspection hammer can be easily adsorbed on the diesel locomotive, making it convenient to pick up and place the inspection hammer; the connection component 3 is provided to facilitate the replacement of the magnet 4, which has better usability.

[0024] For the above solution, regarding the specific structure of the connection component 3:

[0025] Refer to the attached Figure 2 As shown, the connection component 3 includes a housing 31, a mounting rod 32, and a fastening bolt 33; one end of the housing 31 is open and the other end is fixedly connected to the bottom of the hammer handle 1. A mounting rod 32 is vertically arranged inside the housing 31. One end of the mounting rod 32 is connected to the magnet 4 through the fastening bolt 33, and after connection, the magnet 4 contacts the housing 31 to seal the top of the housing 31.

[0026] Among them, the magnet 4 has a rectangular or circular structure. Considering the adsorption area and effect of the magnet 4, the diameter of the magnet 4 is not less than the diameter of the housing 31 so that during the placement of the inspection hammer, the magnet 4 can contact the top or side of the diesel locomotive carriage as much as possible.

[0027] Specifically, regarding the connection structure between the mounting rod 32 and the magnet 4:

[0028] Refer to the attached Figure 2 As shown, one end of the mounting rod 32 is provided with a fixing hole 321. Correspondingly, a counterbore 41 is provided on the upper surface of the magnet 4. The fastening bolt 33 passes through the counterbore 41 and is threadedly connected to the fixing hole 321; in the solution, in order to facilitate the removal of the fastening bolt 33, the fastening bolt 33 is a countersunk head screw or a wing screw.

[0029] To avoid the situation where the magnet 4 cannot be adsorbed due to weakened magnetic force, considering the user's judgment of the magnetic force of the magnet 4 to complete the replacement of the magnet 4, for this reason, refer to the attached Figure 3 and the attached Figure 4 As shown, the connection component 3 further includes a metal ring 34 and an indicating block 35; the metal ring 34 is sleeved outside the mounting rod 32, and an indicating block 35 is arranged on the side of the metal ring 34. The outer end of the indicating block 35 is inserted into an observation port 311 provided on the housing 31, and the indicating block 35 contacts the end of the observation port 311 close to the magnet 4 in the normal magnetic force state of the magnet 4, and contacts the end of the observation port 311 far from the magnet 4 in the demagnetized state of the magnet 4; during the implementation of the solution, the magnet 4 can adsorb the metal ring 34 in the normal state, thereby making the indicating block 35 close to the magnet 4. After the magnetic force of the magnet 4 weakens, it is not enough to adsorb the metal ring 34. Therefore, the indicating block 35 will move away from the magnet 4. The user can know the magnetic force situation of the magnet 4 by observing the position of the indicating block 35, and then judge whether the magnet 4 needs to be replaced.
