Abstract
The utility model discloses an inner spraying water channel structure for a cutting head of an excavator. The inner spraying water channel structure comprises a regular working flow channel, wherein the regular working flow channel is composed of an outer connector, a water inlet sleeve flow channel I, a rotary sealing, a water inlet sleeve flow channel II, a static sealing I, a main shaft flow channel, a static sealing II, a spline housing flow channel, a check valve, a water cavity, a nozzle flow channel and a nozzle that are sequentially communicated. The inner spraying water channel structure also comprises a high pressure water flow channel which is used for communicating the surface of the cutting head and the water cavity; and a dredging flow channel is formed by the high pressure water flow channel, the water cavity, the nozzle flow channel and the nozzle. In the inner spraying water channel structure, the regular working flow channel and the dredging flow channel are separated, high pressure water can flow into the water cavity from the high pressure water flow channel when the nozzle or the nozzle flow channel is dredged, and certain pressure is formed in the water cavity, so that the nozzle or the nozzle flow channel can be dredged; and the high pressure water does not pass through the sealings at various positions, so that the damage to the sealing by the high pressure water is avoided.
Description
Technical field
The utility model relates to a kind of cutting head of roadheader internal spraying channel structure, particularly a kind of Vertical Axis Road-header cutterhead internal spraying channel structure.
Background technology
At present, the Vertical Axis Road-header internal spraying system is short application life, and nozzle or nozzle flow channel easily stop up, and are difficult for after the obstruction unclogging the channel; When directly water under high pressure being fed operate as normal runner (internal spraying runner) mediation nozzle, can destroy sealing, can't use to such an extent as to internal spraying system loses efficacy, thereby reduce the cutterhead service behaviour, and influence dedusting.
Therefore, need improve to the internal spraying channel structure of cutting head of roadheader nozzle or nozzle flow channel stop up to lose efficacy is difficult for the situation of mediation.
Summary of the invention
In view of this, the utility model provides a kind of cutting head of roadheader internal spraying channel structure, not destroying under the prerequisite that internal spraying system seals, can connect the mediation water under high pressure at the scene everywhere, and nozzle or nozzle flow channel are dredged.
Cutting head of roadheader internal spraying channel structure of the present utility model, comprise the operate as normal runner, described operate as normal runner is made of the socket that is communicated with successively, water inlet cover runner I, rotatory sealing, water inlet cover runner II, static seal I, main shaft runner, static seal II, spline housing runner, one way valve, water cavity, nozzle flow channel and nozzle, also comprise the water under high pressure runner that is communicated with cutterhead surface and described water cavity, described water under high pressure runner, water cavity, nozzle flow channel and nozzle constitute the mediation runner.
Further, described water under high pressure runner is the cone runner;
Further, also comprise water under high pressure joint and plug screw, described water under high pressure joint and plug screw all with water under high pressure runner threaded engagement.
The beneficial effects of the utility model are: the utility model separates operate as normal runner and mediation runner, when nozzle or nozzle flow channel are dredged, water under high pressure feeds water cavity from the water under high pressure runner, in water cavity, form certain pressure, thereby nozzle or nozzle flow channel are dredged, water under high pressure seals everywhere without internal spraying system, has avoided the destruction of water under high pressure to sealing; The utility model can not connect the mediation water under high pressure under the down-hole does not need to dismantle the situation of cutterhead, it is dredged, and has improved nozzle or nozzle flow channel and has stopped up to lose efficacy and be difficult for the situation of mediation.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Structural representation when Fig. 1 is the utility model operate as normal;
Structural representation when Fig. 2 dredges nozzle or nozzle flow channel for the utility model.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
Cutting head of roadheader internal spraying channel structure of the present utility model, comprise the operate as normal runner, described operate as normal runner is made of the socket 1 that is communicated with successively, water inlet cover runner I 2, rotatory sealing 3, water inlet cover runner II 4, static seal I 5, main shaft runner 6, static seal II 7, spline housing runner 8, one way valve 9, water cavity 10, nozzle flow channel 11 and nozzle 12, also comprise the water under high pressure runner 13 that is communicated with cutterhead surface and described water cavity 10, described water under high pressure runner 13, water cavity 10, nozzle flow channel 11 and nozzle 12 constitute the mediation runners.
In the present embodiment, described water under high pressure runner 13 is the cone runner; The cone runner is convenient to sealing, can effectively prevent to leak.
Structural representation when Fig. 1 is the utility model operate as normal, as shown in the figure, when the cutterhead operate as normal, water under high pressure runner 13 is clogged with a plug screw 15 with water under high pressure runner 13 threaded engagement, internal spraying water 16 feeds the operate as normal runner from socket 1, at last by nozzle 12 ejections.
Structural representation when Fig. 2 dredges nozzle or nozzle flow channel for the utility model, as shown in the figure, when nozzle or nozzle flow channel obstruction, plug screw 15 is taken out, water under high pressure runner 13 places connect the water under high pressure joint 14 with its threaded engagement, the water under high pressure 17 that high-pressure hydraulic pump provides feeds water cavity 10 from water under high pressure runner 13, forms certain pressure in water cavity 10, thereby nozzle 12 or nozzle flow channel 11 are dredged; Because the restriction of one way valve 9, water under high pressure 17 can not enter the sealing everywhere of internal spraying system, but therefore the mediation runner of flowing through, does not destroy internal spraying system and seal everywhere during mediation.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
