Description
Technical Field
The utility model belongs to the technical field of hydraulic support, concretely relates to hydraulic support of capital pin installation double insurance.
Background
Hydraulic support is in the working face use, roof pressure distributes unevenly, lead to the back timber atress inequality to have become the normality, carry out three machines according to the working face particular case and form a complete set, the anterior supporting size of general support is great, when guaranteeing hydraulic support overall stability, it arranges by the back timber front end to tend to the support front stall, still it is big apart from coal wall accuse apical area, consequently, row's stand working resistance inequality around often appearing, lead to the unstable condition of support low-head "pull out the back post", if there is not timely discovery of operating personnel, cause the probability of support post nest ear part damage to be high. The damage of the column nest lug directly affects the use of the column, the column cannot be fixed to affect the normal lowering, the underground environment is severe, the space is limited, the replacement and repair difficulty is high, and the propelling speed of the working face is greatly affected.
Disclosure of Invention
The utility model discloses support post nest ear part spoilage to current hydraulic support is high, changes the high problem of the repair degree of difficulty, provides a hydraulic support of capital pin installation dual fail-safe.
The utility model adopts the following technical scheme:
the utility model provides a hydraulic support of post apex pin installation dual fail-safe, includes back timber, shield roof beam, tail-boom and base, and the one end of back timber is articulated with the one end of shielding the roof beam, and the other end of shielding the roof beam is articulated with the one end of tail-boom, is equipped with the stand between back timber and the base, and the one end of stand is articulated with the post nest ear of back timber bottom, and the other end is articulated with the base, the bottom of back timber, the upper end of base and the bottom of shield roof beam are equipped with the sensor respectively, are equipped with the drilling that corresponds with the column cap pore pair of stand on the main rib board of post.
And a pin shaft corresponding to the drilled hole is arranged in the drilled hole.
And a stop pin block for connection is arranged on the outer side of the pin shaft.
The utility model has the advantages as follows:
1. the utility model discloses a control back timber pivot angle at back timber, base, shield roof beam installation sensor, carries out alarm control when approaching extreme position to the support is excessively low, plays the prevention guard action, reduces and avoids the emergence number of times of this problem.
2. The utility model discloses a reserve pinhole design is just to drilling stand connecting pin department on the major rib board of post nest ear both sides, can use reserve pinhole installation round pin axle fixed stand after the ear damages, and the round pin axle is connected with the shelves block pin in the outside, guarantees the stand and normally connects the use.
Through the setting, the damage can be avoided to the greatest extent, and if the damage happens, the replacement can be remedied by using a simple and convenient mode.
Drawings
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is a schematic top view of the present invention;
wherein: 1-top beam; 2-a shield beam; 3-tail beam; 4-a base; 5-upright column; 6-a sensor; 7-drilling.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in the figure, a hydraulic support of post apex pin installation dual fail-safe, including back timber 1, shield roof beam 2, tail-boom 3 and base 4, the one end of back timber 1 is articulated with the one end of shield roof beam 2, and the other end of shield roof beam 2 is articulated with the one end of tail-boom 3, is equipped with stand 5 between back timber 1 and the base 4, and the one end of stand 5 is articulated with the post nest ear of back timber 1 bottom, and the other end is articulated with base 4, the upper end of the bottom of back timber 1, base 4 and the bottom of shield roof beam 2 are equipped with sensor 6 respectively, are equipped with the drilling that corresponds with the column cap pore pair of stand 5 on the major rib board of post nest ear both sides.
And a pin shaft corresponding to the drilled hole is arranged in the drilled hole.
And a stop pin block for connection is arranged on the outer side of the pin shaft.
The principle of the utility model is as follows:
the first step is as follows: the hydraulic support adopts an electro-hydraulic system, a sensor is installed on the top beam, the base and the shield beam, the posture of the support is controlled through the sensor, the angle of the support top beam relative to the base is limited, the support is prevented from excessively lowering, the rear upright post is enabled to be transited and pulled up, and the damage to the top beam and the column nest is avoided.
The second step is that: and designing a spare pin hole and installing a spare pin shaft. After the lug of the column nest is broken, the standby pin hole is started to be matched with the column head hole of the column, and the standby pin shaft is installed.
The hydraulic support adopts an electro-hydraulic control system, wherein sensors are arranged at a plurality of positions, the control is carried out aiming at the swing angle of the top beam, and an alarm is given when the support excessively lowers the head. The installation of sensors and the electro-hydraulic control system of the hydraulic support are well known to those skilled in the art.
