Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a snow melting device for melting snow on an orbit.

Snowfall on tracks often remains as it is, which is extremely dangerous for train operation. Conventionally, snow melting equipment has been used to remove snow by spraying water or warm water onto the track surface, but in order to increase the distance of water spraying, In the case of a system in which the jet pipe was rotated by the reaction of the jetted water, the rotation speed was too high, so the snow melting effect was poor. However, if the bending angle of the jet pipe is made looser and the torque is reduced, the rotational speed becomes slower, but there is a problem that the jet pipe cannot turn due to fluctuations in the amount of water supplied.

Furthermore, since the track extends long in one direction, there has been a demand for a snow melting device that has a long water spraying surface on one side along the track.

In view of the above-mentioned problems, the present invention provides snow melting for tracks that has a slow rotational speed of the spout pipe that sprays water and can sufficiently melt snow, and has a long spraying surface in one direction along the track. The purpose is to provide a device.

An embodiment of the snow melting device of the present invention will be described below with reference to the drawings.

(1) is a cylinder shaft whose upper end is stopped, and a peripheral edge (3) is formed on the outer periphery of the midsection to be rotatably inserted into a rotation joint cylinder (2), which will be described later. A communication portion (4) is formed on the upper outer periphery. The rotary joint cylinder (2) has a cylinder hole part (5) which is slidably crowned with the communication part (4) of the cylinder shaft (1) and extends downward beyond the peripheral edge (3). It consists of an outer cylinder part (6), and a jet pipe joint part (7) (?) protrudes obliquely upward at a symmetrical position displaced by 180 degrees on the side of the cylinder hole part (5). A pipe thread is screwed into each end, and water guide holes (8) (8) continuous with the chain pipe thread are opened facing the inner wall of the cylindrical hole (5). In addition, the female thread screwed on the inner periphery of the lower end of the outer cylinder part (6) has a cylinder shaft (1).
An annular retaining ring (lO) rotatably inserted into the shaft cylinder part (9) is screwed into the cylindrical space (A) between the outer cylinder part (6) and the shaft cylinder part (9). is formed by inserting a washer (11) between the peripheral edge (3) and the holding ring (lO).

Furthermore, a washer (
11) is inserted, and the space between the first cylinder shaft (+) and the lower end of the rotary joint cylinder (2) is completely sealed by these, and the rotary joint cylinder (2) is inserted against the cylinder shaft (1). It will start rotating.

Also, (12) and (12) are the jet pipe joint parts (?) (
7) is a spout tube that is screwed to the tip of the spout (
13) (13) is opened, and a water plate (15) is integrally formed at the end of the elongated rod (14) extending from the tip thereof.

In the communication part (4) that comes into sliding contact with the cylinder hole part (5) of the rotary joint cylinder (2), there are two holes unevenly distributed on one side at the height of the water guide hole (8).
Water outlet holes (1B) (18) are drilled, and the water outlet holes (1B) (18) are drilled.
B) An annular small groove (17) that communicates with (1B) and upper and lower annular small grooves (17a) that do not communicate with the water outlet (1B) (
17b) is formed on the outer periphery, and a water hole (1B
) (lft) is provided with the lower annular groove (1
? A small through hole (18) communicating with b) is drilled, and another small through hole (1
8a) is drilled. In addition, (19) is a swinging blade in which a shaft hole (21) is rotatably inserted into a fixed shaft (20) which is erected and fixed at the upper end of the rotary joint cylinder (2), and is formed on the periphery of the shaft. A tension spring (24) is interposed between the four parts (22) and the end plate (23) which is provided on the stepped part (2Oa) provided at the end of the fixed shaft (20). The end plate (23) is fixed to an appropriate rotational position via a locking pin (25), and the swinging blade (19) is elastically biased in the clockwise direction with respect to the rotational joint cylinder (2). At the tips of the side arms (2e) (2e) protruding on both sides of the swinging blade (19), there is a partition plate (27) opposite to the back part of the water shield fixed to the outside of the jet pipe (12), respectively. - A reflecting plate (28) curved in the circumferential direction is formed in one piece, and abutment protrusions (29) protrude from the jet pipe joint part (7) (?) of the rotary joint cylinder (2), respectively. (28) and the side arm (28)
) (2El) collide with each other, and the rotating joint tube (2) and the swinging blade (
18) will rotate together with a swing range of 180 degrees. Note that (30) in the figure is a cap for protecting the tension spring (page 24).

In the snow melting device having the above configuration, when water or hot water is supplied from the riser pipe, the water or hot water passes through the cylinder shaft (1) and the water outlet (
1B) Water flows into the water guide hole (8) (8) from (1B) and is vigorously jetted out from the spout ports (13) of both jet pipes (12) (12). At this time, due to the elasticity of the tension spring (24), the side arms (2B) (2B) touch the contact protrusion (29).
(29) and the jet ports (13) (13) of the jet pipes (+2) (12) open toward the slopes of the reflectors (28) (28), so the jet ports (13) ( The water ejected forcefully from 13) hits the reflector plate (2s) (28) and is bounced back in the circumferential direction, and the swinging blade (+9) momentarily gains counterclockwise torque, causing the rotation joint to The tube (2) is rotated and displaced. Therefore, the water spouted from the spout (13) comes off the reflecting plate (28), flies out, hits the water mirror plate (15), and scatters. In addition, regarding the spout pipe (12), it is possible to adjust the watering range by preparing one with a different angle of inclination of the water plate (15) for both long and short distances and replacing it according to the purpose. It is. When the jet water no longer comes into contact with the reflecting plate (2B) (28), the torque is removed, so the tension spring (24)
), the swinging blade (19) is rotated to the right as if returning to its original position, and its side arms (2B) (2B) engage the abutment protrusion (2B).
29) (29), and the swinging blade (18) and the rotary joint tube (2) are both rotated slightly clockwise from their original positions.

By repeating this, the rotary joint cylinder (2) is intermittently rotationally displaced relative to the cylinder axis (1), and the elastic force of the tension spring (24) can be changed by rotating the end plate (23). The rotation speed can be adjusted by

In addition, as the rotary joint cylinder (2) rotates, the cylinder shaft (1
) The water outlet holes (1B) (1B) have a position where they communicate directly with the water guide holes (8) and a position where they communicate via the annular groove (17). )
(16), the flow rate of water increases and the water ejected from the spout (13) is scattered far, but at a position that communicates with the small annular groove (17), the flow rate of water decreases. The flying distance from the spout (13) becomes shorter. In addition, since the above-mentioned water outlet (ift) (1B) is installed unevenly on the negative side, the water spray surface (B) is on one side of the snow melting device and has a shape that extends long in the front and back direction, and is installed on the side of the track. Then, water will be sprinkled along the trajectory.

As explained above, the snow melting device of the present invention not only can spray water along the raceway surface because the water spraying surface is elongated in one direction, but also has excellent water spraying pipes that can be spun smoothly. It has features such as being able to exhibit snow melting effects and having fewer breakdowns.
