Abstract
The invention relates to a sanding pipe assembled installed on a railcar sanding device, comprising a pipe wall made of rubber materials, and a rigid wire formed from by elastic steel wires and a memory wire formed from by memory alloy elastic wire are installed in the pipe wall. Because the rigid wire and the memory wire are installed in the rubber materials of the sanding pipe, the sanding pipe can automatically restore the original shape after being deformed by the action of external force, so thereby the sanding pipe in the structure can not generate cause the problems that sand is sanded out of a steel rail and a valve core and a valve seat are damaged after being struck impacted by external force.
Description
Technical field
The present invention relates to a kind of sand pipe that is installed on the railcar sanding device.
Background technology
Existing railcar such as diesel locomotive can safety arrestments in the process of operation, and four jiaos at each bogie truck of locomotive all are equipped with sanding device usually.Sanding device can spread sand between wheel and the rail, so that the mode of binding force prevents that tyre skidding and hub surface from being abraded through increasing between the two.
Yet existing sanding device is by a sand reservoir box and is installed in the spool and the valve seat of this sand reservoir box lower bottom part successively, and the sand pipe that is connected with the mouth of valve seat constitutes, and sand pipe is the bend pipe of being processed by metallic material.
This sanding device at first sends the command signal that the spool of sand reservoir box lower bottom part is opened by control setup when work, the sand in the sand reservoir box is fallen on the rail through valve seat and bend pipe.Though the sanding device of this kind structure can increase the binding force between wheel and the rail, can prevent that tyre skidding and protection hub surface from not abraded, because sand pipe is being walked in the process with garage; Obstacle with the track limit bumps sometimes, and the sand pipe in this storage sand device is processed by metallic material, and this tubular elastic limit is less relatively; And not memory under normal conditions, and promptly can produce deformation after the obstacle collision; And the distortion back is not because there is memory can not recover original state; So, the sand pipe of this kind structure in case with obstacle collision after very easily damage, be to be rigidly connected because of itself and spool and valve seat simultaneously; Do the time spent when sand pipe receives bigger external force, also be prone to together damage together with described spool and valve seat.
Summary of the invention
The purpose of this invention is to provide a kind of sand pipe on the railcar sanding device that is provided in that the revertible mode in back solves problems such as sand pipe and spool valve seat damage that is out of shape.
The sand pipe that is installed on the railcar sanding device that the present invention proposes is the tube wall of being processed by elastomeric material, and rigid filaments that is made up of elastic wire and the memory silk that is made up of the memorial alloy elastic yarn are installed in this tube wall.
Said sand pipe is provided with first curve and second curve, and wherein, first curve and the formed bend angle of second curve are the 130-140 degree.The bending direction of said first curve and second curve is vertical each other or vertical basically.Said second curve to free end is a round type.
The sand pipe that is provided on the railcar sanding device proposed by the invention adopts elastomeric material to process; And rigid filaments is installed in elastomeric material and the memory silk is arranged; This kind sand pipe can be restored to the original state after receiving external force effect generation deformation automatically; So,, can not occur sand is spread the problem beyond the rail even if after adopting the sand pipe of this kind structure to receive external force collision yet; Simultaneously, because elastomeric effect, can not make spool and valve seat damage receiving big external force effect, so the service life of sanding device that is equipped with this kind sand pipe is longer yet.
Description of drawings
Accompanying drawing 1 is the surface structure scheme drawing that is provided in 1 one embodiment of sand pipe on the railcar sanding device proposed by the invention;
Accompanying drawing 2 is section-drawings of sand pipe 1 upper area among Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the overall appearance structure that is provided in 1 one embodiment of sand pipe on the railcar sanding device proposed by the invention.This sand pipe 1 is the tube wall of being processed by elastomeric material 11, and rigid filaments 12 that is made up of elastic wire and the memory silk 13 that is made up of the memorial alloy elastic yarn are installed in this tube wall 11.Described rigid filaments 12 can put in one deck with memory silk 13 that (the black part is promptly represented rigid filaments 12 among Fig. 2; Also can represent memory silk 13); Promptly a rigid filaments 12 and memory silk 13 interval types are put; Perhaps several rigid filaments 12 are put with several memory silk 13 interval types, perhaps in tube wall 11, are provided with one deck rigid filaments 12 and one deck memory silk 13 (not providing this kind structure among the figure).Sand pipe 1 is provided with first curve 14 and second curve 15; First curve 14 and second curve, 15 formed bend angles are the 130-140 degree; And the bending direction of first curve 14 and second curve 15 is vertical each other or vertical basically, and promptly both are not at grade.Sand pipe 1 is a round type at second curve 15 to the free end.
Claims (3)
1. be installed in the sand pipe on the railcar sanding device, it is characterized in that: this sand pipe is the tube wall of being processed by elastomeric material, and rigid filaments that is made up of elastic wire and the memory silk that is made up of the memorial alloy elastic yarn are installed in this tube wall.
2. sand pipe according to claim 1 is characterized in that: said sand pipe is provided with first curve and second curve, and wherein, first curve and the formed bend angle of second curve are the 130-140 degree.
3. sand pipe according to claim 2 is characterized in that: said second curve to free end is a round type.
