At present, there is no sand mining device at the lower end of the running part of the locomotive. Patent 2011102776776 discloses a sand mining device for a locomotive body of our company, but in the actual operating environment, the instrument for collecting sand samples is still lacking, and the spatial arrangement of the locomotive front-end obstacle removal device structure cannot be well utilized.

Contents of the invention

In order to overcome the deficiencies of the existing technology, the invention provides a sand mining instrument device at the lower end of the running part of the locomotive.

The technical solution adopted by the present invention to solve the technical problem is: a sand mining instrument device at the lower end of the running part of the locomotive, including the lower end of the original running part of the locomotive where the sand mining instrument is installed, and the sand mining instrument includes a sand mining box and a sand collecting pipe , the sand collection pipe is installed in the sand mining box, and the sand mining box is connected and fastened with the bottom plate of the obstacle remover through bolts. , the mouth of the sand collection pipe is connected with the slot.

According to another embodiment of the present invention, it further includes that the sand collection pipe is a cylindrical steel pipe with an inner diameter of ￠16.

According to another embodiment of the present invention, it further includes that the door of the sand mining box is provided with a door lock structure.

The beneficial effect of the present invention is that the present invention can solve the collection of sand grains acting on the surface of the lower end of the running part of the locomotive under the harsh conditions of wind and sand, and is useful for studying the wind and sand abrasion resistance of the outer surface coating system of the running part of the locomotive and delaying the expiration date of the coating The test basis is provided and has practical value, and the invention has simple structure and convenient installation.

Detailed ways

As shown in Figures 1 and 2, a sand mining device at the lower end of the running part of a locomotive comprises the lower end 1 of the original locomotive running part where the sand mining device 2 is installed, and the sand collecting device 2 includes a sand collecting box 7 and a sand collecting pipe 3. The sand collection pipe 3 is installed in the sand mining box 7, and the sand mining box 7 is connected and fastened with the bottom plate 10 of the obstacle remover 5 through the bolt 4. The sand mining box 7 is provided with a sand mining box door 8 that can be opened and closed freely. The locomotive obstacle remover 5 is provided with a slot 6, and the mouth of the sand collecting pipe 3 communicates with the slot 6. The size, position and angle of the 3 nozzles of the sand-collecting pipe meet the needs of the sand sample collection sample, the second is to meet the needs of the sand sample particle size, and the third is the requirement of the wind direction in the locomotive operation. In order not to affect the arrangement of other structures of the locomotive as much as possible, the sand mining instrument uses the space of the obstacle remover structure device at the front end of the locomotive, and installs the sand harvester on the inner side of the obstacle remover to collect sand samples acting on the lower surface of the running part , for the analysis of its particle size, so as to study the wind and sand resistance performance test of the paint on the lower end of the running part.

As shown in Figures 3 and 4, the sand collection pipe 3 is a cylindrical steel pipe with an inner diameter of ￠16, which ensures the installation, fixation and detachability of the sand mining instrument, and also ensures the stability of the overall structure under the environmental conditions of use. corrosion resistance.

As shown in Fig. 5 and Fig. 6, the door 8 of the sand mining box is provided with a door lock structure 9. The sand collecting pipe can be fixed and taken out conveniently by closing and opening the collection box door, which facilitates the collection of sand samples, and the device has good detachability.

The invention is an instrument for collecting sand samples of locomotives in the actual operating environment. The invention solves the problem of collecting sand particles acting on the lower surface of the running part of the locomotive under severe wind and sand conditions. It is useful for studying the outer surface coating of the running part of the locomotive It is of practical value to provide an experimental basis for the wind and sand abrasion resistance of the system and to delay the failure of the coating.

The sand mining instrument is mainly used for collecting test sand. After the locomotive has been running for a period of time and the sand sample is collected, it should be convenient enough to take out the sand sample. At the same time, the sand mining instrument can be removed when there is no need for sand mining in the future. There is no conflict with other structures of the locomotive, and it is convenient to take sand and disassemble it.

Collect the wind and sand that acts on the lower surface of the running part in the actual application environment of the locomotive, test and study the wind and sand resistance performance of the surface coating system of the running part of the locomotive, and design the surface coating scheme of the running part of the locomotive in a targeted manner, so as to confirm the locomotive under the severe wind and sand conditions. The decorative effect and service life of the surface coating.
