Abstract
The utility model relates to a dustproof cover special for a railway point switch. The dustproof cover comprises a cover body used for being sleeved on one side of the point switch, a through hole for being penetrated through by a detection rod and an actuating rod which are arranged on the point switch is formed on the cover body, the middle section of the cover body is provided with wavy folding ripples, and the diameter of an opening at the front end of the cover body is smaller than that of an opening at the back end of the cover body. According to the dustproof cover, the design of the folding ripple type structure is adopted, so that when the actuating rod on the point switch moves, the cover body is provided with good malleability and waterproof and dustproof during usage, the control circuit portion in the point switch can be protected effectively, and faults can be avoided.
Description
Technical field
The utility model relates to the field of goat, especially a kind of goat Special dustproof cover.
Background technique
When two tracks of railway line converge to a monorail, must there be interpreter mechanism for which single track that two of the desired route selections of railway vehicle converge in track to align, switching mechanism realizes this purpose by the mobile a pair of rail end that is called as track switch, makes two rails of this single track align these two two rails that converge one or the other track in track.But interpreter mechanism is driven by reverse motors, the linear move operation bar of motor or push rod, move track switch in the direction that is transverse to track, by rotating threaded screw member, rotatablely moving of motor shaft can convert the Linear-moving of this implementation to, and the nut of slip or slide block can move along this threaded screw member.When the nut that slides or slide block moved along this threaded screw member, mobile putter came mobile track switch, and except mobile track switch, the nut of slip its end of moving of being everlasting coordinates with mechanism in these ends disconnection motors or reverse motors direction.
what at present interpreter mechanism adopted is switch machine, switch machine and track between by being connected with actuating strut and test rod, due to switch machine all be mounted in the outside, if run into rainy day, snowy day etc., easily cause rainwater to enter on actuating strut and test rod, thereby enter in the Direct box on switch machine, cause the phenomenon such as malfunctioning of switch machine, protective housing in actuating strut and test rod outer cup is all to adopt stationary structure at present, when the actuating strut on switch machine and test rod need to overhaul, need to remove original protective housing, can overhaul, it dismantles trouble, and such protective housing easily causes dust to enter, cause the operate miss of actuating strut and test rod, cause potential safety hazard.
The model utility content
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of goat Special dustproof cover, its waterproof and dustproof is effective, can effectively protect the switch machine inner control circuit.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of goat Special dustproof cover, comprise be used to the body that is nested with on switch machine one side, offer on described body be used to the through hole that places test rod and actuating strut on switch machine, the intermediate section of described body has and is wavy fold line, and described body front opening bore is less than body open rearward end bore.
Have the flanging that concaves on the front edge of described body, the tail end of body has the bound edge that fits with switch machine one side.
The tapered structure of described body.
For can be convenient on the step that body is nested with at switch machine, be connected with at least one convenient mounting ear that body is installed on described bound edge outer side wall.
Convenient for body being nested with on the step of switch machine, described mounting ear quantity is two, and two mounting ears are connected on two outer side walls of bound edge.
In order to have oxidative resistance, anti-ozone and corrosion resistance and vulcanization characteristics, and good insulation preformance, the material of described body is ethylene-propylene-non-conjugated diene rubber, ethylene-propylene-non-conjugated diene rubber is mainly by ethene, propylene and non-conjugated diene hydrocarbon, these three kinds of copolymers form, this kind rubber has minimum proportion, can absorb a large amount of fillers and oil and can influence characteristic.
The beneficial effects of the utility model are; goat Special dustproof cover of the present utility model; adopt the design of fold line formula structure; can make actuating strut on switch machine in when motion; can make body have ductility preferably, in use, can play the purpose of waterproof and dustproof; can effectively protect the control circuit part in switch machine, avoid breaking down.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is that goat Special dustproof of the present utility model is enclosed within the structural representation in using process.
1. bodies in figure, 2. through hole, 3. fold line, 4. flanging, 5. bound edge, 6. mounting ear, 7. switch machine.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
goat Special dustproof cover as shown in Figure 1, comprise be used to the body 1 that is nested with on switch machine one side, the material of body 1 is ethylene-propylene-non-conjugated diene rubber, the tapered structure of body 1, offer on body 1 be used to the through hole 2 that places test rod and actuating strut on switch machine 7, the intermediate section of body 1 has and is wavy fold line 3, body 1 front opening bore is less than body 1 open rearward end bore, has the flanging 4 that concaves on the front edge of body 1, the tail end of body 1 has the bound edge 5 that fits with switch machine one side, be connected with two convenient mounting ears 6 that body 1 is installed on bound edge 5 outer side walls, two mounting ears 6 are connected on two outer side walls of bound edge 5.
Goat Special dustproof cover as shown in Figure 2, be arranged on the switch machine that converges 7 that is used for controlling track of railway one side, at first need to dismantle linkage section on the actuating strut on switch machine 7 and the linkage section on test rod, then the body 1 with this dirt-proof boot is enclosed within on the step of switch machine 7 sides, then utilize anchor ear to embrace on the bound edge 5 of body 1 tail end and form sealing configuration, actuating strut and test rod penetrated from the front end of body 1 from the tail end of body 1 and passed this moment, and fold line 11 is tensile elongation arbitrarily.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to the claim scope.
