Abstract
A novel sanding device for a locomotive is composed of a sandbox. A sanding valve is fixed under the sandbox. A sanding pipe is connected under the sanding valve. A dust filtering board is arranged onthe body of the sanding valve. An air inlet chamber is arranged under the dust filtering board. The air inlet chamber is communicated with an air inlet on the valve body. A sand shakeout pipe is arranged in the sandbox. The upper end of the sand shakeout pipe is connected with a sand shakeout pipe cover and the lower end is communicated with the sanding pipe. A vent pipe is arranged in the sandbox. The upper end of the vent pipe is located above the sandbox chamber and is covered with the vent pipe cover and the lower end is communicated with the sanding pipe. Because the air blows, the sanddrops smoothly, uniformly and controllably so as to guarantee the friction coefficient between the wheel and the track and prevent the phenomenon of locomotive idle running and slope stopping. The airmaintains positive pressure in the sandbox so as to prevent the extraneous steam from entering into the box. The heating member is able to heat the supplied air and further heat the sand in the sandbox with the hot air so as to guarantee the normal sanding in the cold region.
Description
Technical field
The utility model relates to a kind of sanding device, the novel sanding device of particularly a kind of locomotive.
Background technology
Sanding device on the railway locomotive is used for starting and glancing impact increase wheel and interorbital friction coefficient, existing sanding device is that a tool sandbox is arranged, sanding valve is arranged below sandbox, the sanding valve below connects sand pipe, by the unlatching of sanding valve, the sand material in the sandbox is spread between wheel and track.Existing sanding device is difficult for shaking out, stucco amount inequality, and sand production rate is uncontrollable, in time, lacked for a long time, causes wheel and interorbital friction coefficient not enough, causes locomotive wheel spin, stop on the slope, also occurs the unnecessary waste and the harden phenomenon of sand in sandbox of sand easily.
Summary of the invention
The purpose of this utility model provides a kind of sand amount whereabouts easy to control, even, guarantee the locomotive sanding device that wheel and interorbital have enough friction coefficient, stop locomotive wheel spin, phenomenon is stopped on the slope, overcomes the deficiencies in the prior art; Another purpose of the utility model provides a kind of heating function, sand can not occur hardening sanding device of phenomenon that has.
Locomotive sanding device of the present utility model, it comprises sandbox 13, below sandbox 13, be fixed with sanding valve, the sanding valve below connects sand pipe, it is characterized in that: on the valve body 3 of sanding valve, be provided with dust-filtering plate 9, there is inlet chamber 17 below of dust-filtering plate 9, and inlet chamber 17 is communicated with admission port 15 on the valve body 3; In sandbox 13, be provided with knockout pipe 10, the last termination knockout shroud 11 of knockout pipe 10, the lower end is connected with sand pipe 5; Be provided with breather pipe 2 in sandbox 13, the upper end of breather pipe 2 is positioned at sandbox 13 inner chambers top and is covered with breather cap 19, and the lower end is connected with sand pipe 5.
Locomotive sanding device of the present utility model, wherein said dust-filtering plate 9 inboards are provided with the electric heating part 14 that joins with electrical controller.
Locomotive sanding device of the present utility model, unobstructed, even, controlled when sand is fallen owing to there is gas to blow, guaranteed the friction coefficient between wheel and the track, overcome locomotive wheel spin, phenomenon is stopped on the slope; Gas makes and keeps malleation in the sandbox, has prevented from that extraneous steam from entering to cause hardening or freezing of sand in the case.Because heating member is arranged, when needs were dried heating to grit, heating member can heat the gas that infeeds, and utilizes hot air that the sand in the sandbox is heated, and guarantees normally to carry out in the stucco of cold zone.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is that K shown in Figure 1 is to enlarged diagram;
Fig. 3 is an A portion enlarged diagram shown in Figure 1.
The specific embodiment
As Figure 1-3: 13 is sandbox, at the oblique upper of sandbox 13 sandbox door mechanism 12 is installed.The below screw of sandbox 13 is connected with block 1, and block 1 is connected with valve body 3 bolt of below.
Between valve body 3 upsides and block 1, clamp the ventilative dust-filtering plate 9 of powdered metallurgical material, be equipped with packing seal in the both sides up and down of dust-filtering plate 9.Below dust-filtering plate 9, form inlet chamber 17.
10 is the knockout pipe, and the lower end of knockout pipe 10 is passed between dust-filtering plate 9 and the valve body 3 and is threaded.Be connected to knockout shroud 11 in the upper end of knockout pipe 10.
Screw retention has bottom 7 in the bottom of valve body 3, and the attachment cap 6 that has been threaded below bottom 7 middle parts is installed with sand pipe 5 by attachment cap 6 and wedge-shaped sleeve 20.In valve body 3 inboards valve pocket 21 is arranged, knockout pipe 10 is interconnected by valve pocket 21 with sand pipe 5.Plug 4 has been threaded on bottom 7.
Be provided with breather pipe 2 in sandbox 13, the top of breather pipe 2 is connected to breather cap 19, and the below is passed dust-filtering plate 9 and is threaded with valve body 3.The inner chamber of breather pipe 19 is connected with sand pipe 5 by valve pocket 21.
In the side of valve body 3 electric heating assembly 8 is installed, the heat generating member 14 in the electric heating assembly 8 is positioned at the inner chamber of dust-filtering plate 9.Electric heating assembly 8 is connected with electrical controller lead on the locomotive.
Be provided with two admission ports 15 on valve body 3, admission port 15 is connected with the inlet chamber 17 of dust-filtering plate 9 belows by the air flue 16 of valve body 3 inboards.Be provided with filter 18 in the inboard of admission port 15 and be used for filtration the gas that enters.
During installation, two admission ports 15 join by the pneumatics on adaptor union and pipeline and the locomotive, and one of them is the normality air feed, keep being in barotropic state in the sandbox, and extraneous steam is difficult for entering.Air feed when another is stucco.As the needs stucco, the gas permeation dust-filtering plate 9 that enters air flue 16, inlet chamber 17 from admission port 15 blows to the sand in the sandbox 13, make the sand upward movement, and the gap between knockout pipe 10 and knockout shroud 11 enters in the knockout pipe 10, spread between wheel and track by sand pipe 5 through valve pocket 21 downwards then.The gas that enters in the sandbox 13 enters in the breather pipe 2 from breather pipe 2 upper ends, discharges by valve pocket 21, knockout pipe 5 then.When needs were dried heating to sand, heating component heated the air of the normality air feed of process dust-filtering plate 9, utilizes hot air that the sand in the sandbox is heated, and guarantees normally to carry out in the stucco of cold zone.
