Description

Technical Field

[0001] The utility model relates to the technical field of railway turnout cleaning, in particular to a railway turnout snow and sand removal blowing device. Background Art

[0002] A turnout is a line connection device that allows locomotives and vehicles to transfer from one track to another. It is also one of the weak links of the track. It is usually laid in large quantities at stations and marshaling yards. With turnouts, the line's capacity can be fully utilized. Even for single-track railways, laying turnouts and building a fork line that is longer than the length of the train can allow trains to run in opposite directions. Snow and sand will reduce the friction between the rails and wheels, increase the braking distance of the train, and affect the safety of train travel; fine particles and chemicals in the sand may corrode the surface of the rails, causing damage to the rails and reducing their service life; snow and sand may clog the sensors and equipment of the signal system, affecting the accuracy and reliability of the signal.

[0003] Snow and sand conditions at turnouts vary depending on geographic location, climate conditions and seasonal changes; in areas with thicker snow or more sand, greater downforce is required to ensure effective removal; while in areas with thinner snow or less sand, excessive downforce may cause unnecessary equipment wear or damage

[0004] In actual use, the downward pressure adjustment method of the snow and sand removal blowing device is relatively complicated, requiring the operator to perform tedious adjustment steps; this not only increases the difficulty of operation, but may also affect work efficiency.

[0005] Therefore, a railway turnout snow and sand removal blowing device is needed to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a railway turnout snow and sand removal blowing device to solve the problem that the downforce adjustment method proposed in the above background technology is relatively complicated.

The joint assembly 3, the downward pressure adjustment assembly 3 includes an adjustment rod 31, the adjustment rod 31 is a telescopic rod, the adjustment rod 31 is installed between the connecting block 23 and the purge base 25, and an adjustment bolt 32 is arranged on the adjustment rod 31. The support assembly 1 provides stable support for the entire device to ensure that the device can work stably during the snow and sand removal process; the first connecting rod 22 ensures that the purge assembly 2 can be firmly installed on the support base 11; when the adjustment rod 31 is extended or shortened, it will drive the angle of the second connecting rod 24 to change, so that the purge base 25 can be lowered or raised. After the angle is fixed, it is fixed by the adjusting bolt 32, so as to adjust the contact area with the turnout surface and the downward pressure.

[0022] Four sets of moving wheels 12 are installed at the lower end of the supporting base 11, and the moving wheels 12 enhance the mobility and flexibility of the railway turnout snow and sand removal blowing device, so that the device can perform snow and sand removal work more efficiently and conveniently.

[0023] Mounting holes 111 are provided on both sides of the front end of the support base 11, and the first connecting rod 22 is installed inside the mounting hole 111. An angle fixing bolt 4 is provided on the side of the mounting hole 111.

[0025] An air outlet 251 is provided on the blowing base 25, and a blower 21 is fixedly installed on the upper end of the supporting base 11. The blower 21 is connected to the air outlet 251 through a connecting pipe 28. The wind force generated by the blower 21 is transmitted to the air outlet 251 through the connecting pipe 28. While the brush 27 is cleaning, the wind force output by the air outlet 251 blows away the accumulated snow and sand, thereby realizing rapid, efficient and thorough cleaning of the railway turnout.

[0026] A scraper 5 is provided at the lower end of the second connecting rod 24. The scraper 5 directly contacts the surface of the railway turnout and effectively scrapes away the snow, sand, ice and the like which are difficult to be blown or brushed off on the turnout through its hard material properties.

[0027] As an embodiment of the utility model: when using the snow and sand removal blowing device for railway turnouts, first use the four sets of moving wheels 12 to move the device to the turnout position where the operation is required, adjust the angle of the first connecting rod 22 as needed, and fix the position of the first connecting rod 22 by rotating the angle fixing bolt 4 to ensure that the blowing base 25 can be correctly aligned with the turnout surface;

[0028] According to the actual situation of snow and sand on the turnout, the adjusting rod 31 in the downward pressure adjusting assembly 3 is adjusted to extend or shorten, thereby changing the contact area and downward pressure between the blowing base 25 and the turnout surface, and the adjusting bolt 32 is used to fix the position of the adjusting rod 31 to ensure that the downward pressure remains stable during operation. The power switches of the drive motor 26 and the blower 21 are turned on, and the drive motor 26 is started to make the brush 27 start to rotate at high speed to physically remove the snow and sand on the turnout surface. At the same time, the wind force generated by the blower 21 is transmitted to the blowing port 251 through the connecting pipe 28, and while the brush 27 is cleaning, the wind force output by the blowing port 251 blows away the snow and sand, thereby achieving fast, efficient and thorough cleaning; thereby completing the use of the railway turnout snow and sand removal blowing device.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
