Description

Technical Field

[0001] The utility model relates to the field of locomotive sand boxes, in particular to a locomotive sand box which is convenient for maintenance and filtration. Background Art

[0002] The locomotive sandbox is a crucial component, primarily used to increase friction between the wheels and rails on wet, slippery, icy, or steeply sloped roads. When these conditions result in insufficient traction or weakened braking, sand from the sandbox is spread between the wheels and rails, forming a film that enhances friction and helps the locomotive travel and brake smoothly. This device is particularly important in adverse weather conditions, effectively preventing the locomotive from slipping and improving operational safety.

[0003] A search revealed Chinese patent publication number CN206031375U, which discloses a sand box filter device comprising a fastening rotary cover and a sand box connection device. The fastening rotary cover is mounted on the sand box connection device via a fixed shaft. The fastening rotary cover comprises a bracket, a steel plate, a fastener, and a rotating cover. The bracket is mounted on the steel plate, the fastener is mounted on the steel plate, and the rotating cover is mounted on the steel plate. A sand inlet is provided in the middle of the sand box connection device, and a precision filter is installed in the sand inlet. The device has a reasonable structural design, is simple to install, and is easy to use. The fastening rotary cover improves its fastening properties, and the precision filter is provided at the sand inlet of the sand box connection device, which not only filters out impurities in the sand but also improves the cleanliness of the sand, thereby improving work efficiency.

[0004] Although this technical solution filters the inside of the sand box by setting a precision filter to ensure that the sand spreader is not blocked, in actual use, the precision filter will filter out a large amount of debris particles during the filtering process. When these debris particles accumulate to a certain extent, they will affect the sinking effect of the sand inside the sand box. Therefore, the precision filter needs to be removed and cleaned, which increases the labor intensity of maintenance and increases the preparation time of the locomotive. Therefore, a locomotive sand box that is easy to maintain and filter is proposed to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 3The utility model provides an embodiment: a locomotive sand box that is easy to inspect and filter, including a sand box 1 for storing sand, a box cover assembly 2 is provided on the top of the sand box 1, and the box cover assembly 2 is opened to conveniently add sand to the inside of the sand box 1, and a sand spreader assembly 3 is provided at the bottom of the sand box 1. When the sand spreader assembly 3 is opened, the sand spreader assembly 3 can evenly spread sand between the wheel and the track, and the top of the sand spreader assembly 3 is fixedly connected with a filter assembly by a bolt 12. The filter assembly is used to prevent debris from entering the inside of the sand spreader assembly 3, ensuring that the sand spreader assembly 3 is not blocked, and preventing To prevent the sand spreader assembly 3 from being damaged, an inspection port 4 for convenient inspection of the internal sand box 1 is provided on the left outer wall of the sand box 1. An inspection component is hinged on the top of the inspection port 4. The inspection component is used to observe and inspect the inside of the sand box 1. The inspection component includes an inspection door 5. The top of the inspection door 5 is hinged on the top of the inspection port 4. The bottom end of the inspection door 5 is detachably connected to the bottom end of the inspection port 4 through a lock. The inspection port 4 can be easily entered by opening the lock at the bottom of the inspection door 5. An observation glass 6 is fixedly connected to the inside of the inspection door 5, and the blockage of debris particles inside the sand box 1 can be observed through the observation glass 6.

[0030] Reference Figure 3-Figure 4 , a buffer seat 7 is fixedly connected to the inside of the inspection assembly, and the inside of the inspection door 5 is fixedly connected to the outside of the buffer seat 7. There are several groups of buffer seats 7, which are evenly distributed on the inside of the inspection door 5 and are all arranged on the periphery of the observation glass 6. A buffer groove 8 is opened inside the buffer seat 7, and a buffer round block 10 is elastically connected to the inside of the buffer groove 8 through a buffer spring 9. When the buffer round block 10 is not under force, the buffer spring 9 will push the buffer round block 10 inward, so that the buffer round block 10 moves toward the inside of the sand box 1. One end of the buffer spring 9 is fixedly connected to the inside of the buffer groove 8, and the other end of the buffer spring 9 is fixedly connected to the buffer The round block 10 is close to one side of the buffer groove 8, and the outer periphery of the buffer round block 10 is slidably connected to the inside of the buffer groove 8. The buffer groove 8 limits the buffer round block 10 to slide along the inner wall of the buffer groove 8. The buffer round block 10 is fixedly connected to the side away from the buffer spring 9 with a protective cage 11. The protective cage 11 is composed of multiple groups of curved horizontal bars and vertical bars. When sand is added to the inside of the sand box 1, the staggered protective cages 11 will reduce the speed at which the sand descends. At the same time, larger debris particles can also be blocked by the protective cage 11 when falling, preventing the debris particles from hitting the observation glass 6, which is located on the inner side of the protective cage 11.

[0031] Reference Figure 1-Figure 2The filter assembly includes a mounting plate 13 that serves as a fixed connection. The four corners of the mounting plate 13 are fixedly connected to the sand spreader assembly 3 by bolts 12. A filter screen 14 is fixedly connected to the top of the mounting plate 13. The filter screen 14 is provided with finer filter holes, which can filter out large particles in the sand that do not meet the standard requirements and debris in the sand (such as grass roots, slag, cigarette butts, waste paper, plate agglomerates, etc.) and retain them in the sand box 1 to ensure that the sand spreader assembly 3 is not blocked. An isolation column 15 is fixedly connected to the top of the mounting plate 13. The isolation column 15 is provided with several groups, and several groups of isolation columns 15 are evenly distributed on the top of the mounting plate 13. The isolation columns 15 are of two types with different lengths. The two types of isolation columns 15 are staggered, and the debris particles can be separated by the isolation columns 15, so that there are gaps between the debris particles, ensuring that finer sand can fall through the gaps between the debris particles.

[0032] Working principle: After the locomotive has been running for a period of time, the inside of the sand box 1 can be observed through the observation glass 6. If there are a lot of debris particles, the inspection door 5 can be opened to clean the inside of the sand box 1. When new sand is added to the sand box 1, the sand falls and contacts the protective cage 11. The protective cage 11 moves outward, driving the buffer block 10 to squeeze the buffer spring 9, generating elastic force and buffering the impact of the sand. The protective cage 11 can also reduce the speed of the falling sand and block the impact of large debris particles on the observation glass 6, preventing damage to the observation glass 6. When the sand spreader assembly 3 needs to be operated, the sand spreader assembly 3 is opened and the sand inside the sand box 1 is discharged. The sand moves downward and the debris particles are blocked by the filter 14 and fall on the isolation columns 15 of varying lengths. The isolation columns 15 create gaps between the debris particles, allowing the sand to continue to fall through the gaps between the debris particles, increasing the sand throughput rate.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
