Abstract
The utility model relates to a kind of Telescopic beam of hydraulic bracket wall supporting jack fixing device, belongs to coal-mine hydraulic support.The utility model comprises: back timber, extensible canopy, wall supporting jack, face guard, two elongated window are provided with bottom back timber, it is characterized in that, extensible canopy is arranged with sleeve, sleeve interior surface has annular groove, and sleeve is built with gudgeon, and gudgeon one end is provided with the first bearing pin, first bearing pin two ends are placed in annular groove respectively, and the gudgeon other end is connected with wall supporting jack.The utility model gudgeon one end is placed in sleeve by the first bearing pin, the gudgeon other end is connected with wall supporting jack, be connected bottom gudgeon with at the bottom of wall supporting jack cylinder, wall supporting jack piston rod is connected with wall supporting, so just give wall supporting jack a supporting role, and limit the rotation of gudgeon around axis.Simplify the type of attachment between extensible canopy face guard, reduce installation, maintenance difficulty, alleviate labour intensity.
Description
Technical field
The utility model relates to a kind of Telescopic beam of hydraulic bracket wall supporting jack fixing device, belongs to coal-mine hydraulic support.
Background technology
Current existing hydraulic support mainly adopts joist to connect face guard and extensible canopy structure.The hydraulic rack structure of joist structure is complicated, and installation, maintenance inconvenience, extensible canopy bulk strength is relatively weak, and manufacturing cost is higher.
Utility model content
The purpose of this utility model be to provide one can structure simple, installation, maintenance convenient, a kind of Telescopic beam of hydraulic bracket wall supporting jack fixing device that production cost is low.
Technical solution
The utility model comprises: back timber, extensible canopy, wall supporting jack, face guard, two elongated window are provided with bottom back timber, it is characterized in that, extensible canopy is arranged with sleeve, sleeve interior surface has annular groove, and sleeve is built with gudgeon, and gudgeon one end is provided with the first bearing pin, first bearing pin two ends are placed in annular groove respectively, and the gudgeon other end is connected with wall supporting jack.
Described first bearing pin adopts the bearing pin of two end band telescopic shafts.
The pod of center line was also provided with in described sleeve.
Described first bearing pin adopts common bearing pin, and is placed in annular groove by pod in sleeve.
In described sleeve, pod center line and extensible canopy end face angle are 0 ° ~ 45 °.
Described first bearing pin center line and extensible canopy end face angle are 45 ° ~ 90 °, limit moving axially of gudgeon.
Advantage of the present utility model and effect are:
1. the utility model gudgeon one end is placed in sleeve by the first bearing pin, the gudgeon other end is connected with at the bottom of wall supporting jack cylinder, wall supporting jack piston rod is connected with wall supporting, so just gives wall supporting jack a supporting role, and limits the rotation of gudgeon around own axes.Simplify the type of attachment between extensible canopy face guard, reduce installation, maintenance difficulty, alleviate labour intensity.
2. be provided with two elongated window bottom back timber, for the transverse shifting of gudgeon relative to back timber.Back timber entirety is box-structure, to ensure back timber bulk strength.
3., at sleeve and the gusset that extensible canopy top board welds, add sleeve strength.
4. the utility model structure is simple, and consumptive material is less, reduces manufacturing cost.
5. the utility model remains extensible canopy middle housing, improves extensible canopy intensity.
Accompanying drawing explanation
Fig. 1 is the utility model assembling schematic diagram;
Fig. 2 is the utility model extensible canopy and tube-in-tube structure schematic diagram;
Fig. 3 is the A-A view of Fig. 2;
Fig. 4 is the utility model back timber base plate gudgeon moving window schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail:
See Fig. 1-Fig. 4, the utility model gusset 3 is welded on sleeve 6 with on extensible canopy 1 top board, and sleeve 6 is welded in the sleeve hole on extensible canopy 1.Then extensible canopy 1 is connected with face guard 10.Then extensible canopy 1 is loaded in back timber 2.Again the first bearing pin 4 is loaded in gudgeon 5, and loaded by sleeve 6 pod in the annular groove of sleeve 6, after gudgeon 5 being rotated 45 ° ~ 90 °, limit moving axially of gudgeon 5.Then be connected bottom gudgeon 5 with wall supporting jack 8 cylinder bottom by the second bearing pin 7, wall supporting jack 8 piston rod is connected with face guard 10 by the 3rd bearing pin 9, limits the rotation of gudgeon 5 around axis.
Extensible canopy 1 is contained in back timber 2, and sleeve 6 is contained in extensible canopy 1, and gudgeon 5 is contained in sleeve 6, and wall supporting jack 8 two ends are connected with face guard 10 with gudgeon 5 respectively.When extensible canopy 1 moves relative to back timber 2, band moving sleeve 6, gudgeon 5, face guard 10, wall supporting jack 8 parts therewith move.Get with the process regained at face guard 10, due to wall supporting jack 8 cylinder bottom and gudgeon 5 hinged, gudgeon 5 pairs of wall supporting jack 8 serve supporting role, make wall supporting jack 8 piston rod stretch out with retraction smooth.
