Description
Technical field
The utility model is related to a kind of coal mine fully-mechanized mining working hydraulic support more particularly to a kind of fully-mechanized mining working hydraulic pressure branch
The embedded telescoping mechanism of frame.
Background technology
There is phenomena such as roof fall, wall caving in order to avoid advanced fracture occurs for top plate in production process in fully-mechanized mining working, must
Must reduce in time beam-ends away from.The method of generally use is to add extensible canopy in top beam front end.
Extensible canopy is the overall structure being welded by steel plate splicing group, and main function is advance support, when coalcutter is mined
Later, before not moving frame, top plate is protected in extensible canopy stretching.This structure non-support width can be reduced to and be allowed above the roads Shi Ji
Within range, supporting is avoided to postpone, immediate support is realized to the top plate exposed.
Extensible canopy generally use is built-in structure at this stage, and subsidiary joist is connected with top beam, telescopic jack cloth
It is placed on the downside of top beam body.On the one hand main frame quality is increased；On the other hand coalcutter can be reduced again crosses machine height.
Meanwhile extensible canopy usually used at this stage is mostly five box-structures, and joist, wall supporting jack are carried in the middle part of beam body
Connect joist and the small four-bar mechanism on wall supporting；Four babinets of both sides are integrally built in top beam front end, and telescopic jack is then
It is arranged on the downside of top beam body.This structure makes the too small by height of holder downside coalcutter, when coal seam distribution is relatively thin, holder
Still needing to liter frame to certain altitude position could make coalcutter pass through；Simultaneously because rising, frame is excessively high, and coal mining machine roller may be cut
To the non-coal rock layer in top, not only there is a degree of damage to roller, but also make cutting speed excessively slow, and influenced manufacturing schedule.
Utility model content
The purpose of this utility model is to provide a kind of embedded telescoping mechanism of fully-mechanized mining working surface hydraulic support.
The purpose of this utility model is achieved through the following technical solutions：
The embedded telescoping mechanism of the fully-mechanized mining working surface hydraulic support of the utility model, including top beam and cross section are five
The front end of the extensible canopy of body structure, the extensible canopy is hinged with wall supporting, and joist is not set between the top beam and extensible canopy, described
The thickness of three babinets is less than the thickness of the babinet of both sides in the middle part of extensible canopy, and it is recessed knot to form three babinets in the middle part of extensible canopy
Structure is set between the top beam and extensible canopy there are two telescopic jack, and the lower edge of the top beam front end lip plate is close to both sides
Position is respectively equipped with groove, and two telescopic jacks are respectively embedded into two grooves of top beam and the recessed structures of extensible canopy.
The working face that the utility model embodiment provides it can be seen from above-mentioned technical solution provided by the utility model
The embedded telescoping mechanism of face hydraulic support not only alleviates weight, but also can ensure the machine height excessively of coalcutter.Pass through the device
Use, it is insufficient to solve the problems, such as that coalcutter crosses machine height during fully mechanized mining.

Specific implementation mode
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The embedded telescoping mechanism of the fully-mechanized mining working surface hydraulic support of the utility model, preferable specific implementation mode
It is：
Including the extensible canopy that top beam and cross section are five body structures, the front end of the extensible canopy is hinged with wall supporting, institute
It states and does not set joist between top beam and extensible canopy, the thickness of three babinets is less than the thickness of the babinet of both sides in the middle part of the extensible canopy,
It is recessed structures to form three babinets in the middle part of extensible canopy, sets that there are two telescopic jacks between the top beam and extensible canopy, described
The lower edge of top beam front end lip plate is respectively equipped with groove close to the position of both sides, and two telescopic jacks are respectively embedded into the two of top beam
In the recessed structures of a groove and extensible canopy.
It is equipped with connecting seat in the middle part of the rear end of the extensible canopy, it is very heavy that connection wall supporting is equipped between the connecting seat and wall supporting
Top.
The middle part of the top beam front end lip plate is oblong aperture.
The embedded telescoping mechanism of the fully-mechanized mining working surface hydraulic support of the utility model not only alleviates weight, but also can protect
That demonstrate,proves coalcutter crosses machine height.By the use of the device, it is insufficient to solve the problems, such as that coalcutter crosses machine height during fully mechanized mining.
Specific embodiment：
As shown in Fig. 1 to Fig. 2 d, the utility model uses five box-structures with conventional extensible canopy, unlike：
The utility model eliminates joist, and three babinets in the middle part of extensible canopy are thinned in the case where strength check allows；After extensible canopy
End installation a connecting seat, for connecting wall supporting jack；An oblong aperture is opened up in top beam front center, is connected for wall supporting jack
There are sufficient spaces for the movement of seat.Two grooves are opened up in top beam front end both sides simultaneously, for installing telescopic jack；It will be originally outer
The telescopic jack set is embedded in side in top beam body, this structure greatly reduces original flexible, wall supporting jack the space occupied.
In Fig. 3 it can be seen that, when the minimum mining height 2000mm of hydraulic support, coalcutter on the downside of set cap still there are
128mm crosses machine space, can meet the cycle operation of coalcutter during fully mechanized mining completely.
The utility model not only ensure that the supporting intensity of extensible canopy, but also alleviate weight support frame, it is most important that increase
Coalcutter crosses machine height, effectively prevents the phenomenon that coal mining machine roller cuts non-coal seam, further ensures coal work
Manufacturing schedule；It is reduced simultaneously as roller cuts non-coal seam so that the impurity in raw coal is effectively administered, and is reduced follow-up
The time of washed coal work and difficulty, substantially increase economic benefit, are a kind of effective optimization designs.
The key problem in technology point of the utility model is：
1, the mode of telescopic jack connection top beam and extensible canopy is embedded, including extensible canopy concave configuration and top beam two
The groove structure at end；
2, telescoping mechanism cancels the connection type of joist, but middle and back is equipped with wall supporting jack connecting seat, while top beam
Front center opens up square hole, ensures the movement locus of wall supporting jack with this.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
Subject to the scope of protection of the claims.
