Description
[technical field]
The utility model relates to transportation device field, colliery, especially relates to a kind of push unit for mobile coal mine work area scrapper conveyor head, tail.
[background technology]
Known, scrapper conveyor is transportation device important in Coal Transport process, and it is mainly used in longwall mining driving surface, and bears transportation burden; The principle of work of scrapper conveyor is using the bearing piece of unlimited chute as coal, spoil or material etc., scraper plate is fixed on chain and forms scraper chain, and as driving component, after head driving section starts, the sprocket wheel on head axle is driven to rotate, make scraper chain circular flow, thus drive material to move along chute, until to chain-drive section unloading; But, in actual applications, the passing of blast mining face in coal mine scrapper conveyor all relies on the artificial utensils such as individual prop that use to pass substantially, owing to still there is no special passing equipment at present, therefore, often cannot follow up in production process passing scrapper conveyor in time, namely the passing of scrapper conveyor head, tail can only withstand on cantilever support rear column or pushing and sliding on the spoil of old man by individual prop, the potential safety hazards such as this very easily causes rear column to tilt, and supporting is unstable, and supporting situation is poor and top is inclined, top is sliding; Simultaneously, because the head of scrapper conveyor, tail weight are larger, when adopting individual prop to pass, it passes fulcrum on individual prop or old man's spoil, and coal mine work area base plate is softer, and ponding is more, therefore, these factors have directly caused the passing of scrapper conveyor head, tail abnormal difficult, namely existing scrapper conveyor head, not only labor strength is large in passing process for tail, and potential safety hazard is also more.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of scrapper conveyor head, tail shifting device, the object that described device can realize scrapper conveyor head fast and effectively, tail is passed along with the propelling of driving surface.
For achieving the above object, the utility model adopts following technical scheme:
A kind of scrapper conveyor head, tail shifting device, described device comprises lower bottom base, glide path, bilge logs, lower connecting base, jack, upper connecting base and upper poppet; Described lower bottom base upper side is fixed with glide path, and the upper side tail end that lower bottom base correspondence is positioned at glide path side is fixed with lower connecting base, and this lower connecting base is connected with the tail end of jack by connecting pin; Described jack is parallel with glide path, and the head end of jack is connected with upper connecting base by bearing pin, and this upper connecting base is fixedly connected with the bottom faces head end of upper poppet; Be fixedly connected with the top of bilge logs in the middle part of described upper poppet bottom faces, this bilge logs is inverted arcuate structure, and bearing fit corresponding to the top of glide path; The top surface of upper poppet is provided with steady nail, and the steady nail both sides that are positioned at bilge logs relative to jack.
Further, described upper poppet is provided with the connecting bore for fixing scrapper conveyor head or tail.
Further, described bilge logs and glide path are made by the solid drawn pipe of 27SiMn.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Scrapper conveyor head described in the utility model, tail shifting device structure are simple, good looking appearance, are convenient to install, and are easy to operation; Described device not only effectively can reduce self taking driving surface pedestrian and transport channel under the prerequisite ensureing intensity, but also can effectively reduce the basis of passing resistance reach realize scrapper conveyor head fast, object that tail is passed with the propelling of driving surface.

[detailed description of the invention]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Scrapper conveyor head by reference to the accompanying drawings described in 1 ~ 2, tail shifting device, described device comprises lower bottom base 1, glide path 2, bilge logs 3, lower connecting base 4, jack 6, upper connecting base 8 and upper poppet 9; Described lower bottom base 1 upper side is fixed with glide path 2, and the upper side tail end that lower bottom base 1 correspondence is positioned at glide path 2 side is fixed with lower connecting base 4, and namely lower connecting base 4 is fixed on the tail end of lower bottom base 1 upper side, and is relatively positioned at the side of glide path 2; Lower connecting base 4 is connected with the tail end of jack 6 by connecting pin 5, this jack 6 is parallel with glide path 2, and the head end of jack 6 is connected with upper connecting base 8 by bearing pin 7, this upper connecting base 8 is fixedly connected with the bottom faces head end of upper poppet 9, namely go up poppet 9 and can carry out synchronous shift with the expanding-contracting action of jack 6, thus reach with this object that head 11 or the tail of the scrapper conveyor being fixed on upper poppet 9 upper side are passed;
For the benefit of go up poppet 9 with jack 6 synchronization action, the top that can be by cross section the bilge logs 3 of reversed arced structure is fixedly connected in the middle part of the bottom faces of upper poppet 9, with at the bottom of the inner arc of this bilge logs 3 with the top of glide path 2 corresponding bearing fit, namely go up poppet 9 and can be carried out slide displacement smoothly by the bearing fit between bilge logs 3 and glide path 2 when action; For actv. reduces to pass resistance, described bilge logs 3 and glide path 2 all adopt the solid drawn pipe of 27SiMn to make, due to this pipe through modified, Linear cut and fine grinding shaping, and its slideway contacting surface adopts chromium plating process, require that roughness reaches Ra3.2, therefore, this actv. has ensured guiding particularity between bilge logs 3 and glide path 2 and smoothness;
For avoiding the head 11 of scrapper conveyor or tail left and right skew to occur when upper poppet 9 displacement, steady nail 10 can be set at the top surface of upper poppet 9, to reach fixing and the object of skew occurs for limiting scraper machine head 11 or tail; As required, for ease of being fixed head 11 or the tail of scrapper conveyor by steady nail 10, described steady nail 10 and jack 6 be the relative both sides being positioned at bilge logs 3 respectively; Simultaneously, for strengthening fixed effect, multiple connecting bore for fixing scrapper conveyor head 11 or tail can also be set out with it at the plate of upper poppet 9, thus reach the object utilizing bolt the head 11 of scrapper conveyor or tail and upper poppet 9 actv. to be fixed together.
Implement scrapper conveyor head described in the utility model, during tail shifting device, first the head 11 of scrapper conveyor or tail are fixed on the upper side of upper poppet 9, then jack 6 is started when needs are passed, poppet 9 in the flexible drive of jack 6 is utilized to move forward along the sliding pair be made up of bilge logs 3 and glide path 2, and drive head 11 or the tail synchronous reach of scrapper conveyor simultaneously, due to bilge logs 3 employing is arcuate structure, curved fitting surface between itself and glide path 2, therefore, the object adjusting left and right height according to transitional slot slope change can be reached in the process of movement by this arc fitting surface, when the head 11 of scrapper conveyor or tail move into place, be fixed by external force, and then shrink jack 6, now, because the head 11 of scrapper conveyor or tail are firmly fixed, therefore, described device can complete reach under the application force of jack 6, and returning to incipient state, circulation performs aforesaid operations, and described device just can drive the head 11 of scrapper conveyor or tail to reach the object of passing fast with the propelling of driving surface.
The non-detailed portion of the utility model is prior art, therefore the utility model is not described in detail.
