Description

Top pillar pit protection and standby device

Technical Field

The utility model relates to a support pillar nest protection and spare device belongs to hydraulic support equipment technical field in the pit.

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 support post nest otic placode part damage's probability high. As shown in figures 1-3, the rod head 8 of the hydraulic telescopic upright post 6 is provided with a hinge hole 9, the pin 7 passes through the hinge hole 9 and is embedded between the column socket ear plates 2, and the rod head 8 is pressed against the lower part of the column socket body 1. The use of the column is directly influenced by the damage of the column socket ear plate 2, the column cannot be fixed to normally fall, the underground environment is severe, the space is limited, the replacement and repair difficulty is high, and the propelling speed of a working face is greatly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a post nest protection and standby device has overcome the not enough of prior art existence, provides a protection and standby device that prevents further damage of back timber post nest.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a top column nest protection and standby device, includes back timber main part and the column nest body of welding in the back timber main part, and the both ends of column nest body are equipped with the gusset, and the both sides of column nest body are provided with 2 pairs of column nest otic placodes, and every to column nest otic placode parallel arrangement is in the inboard of gusset, and the gusset sets up with the column nest otic placode is perpendicular, and the outside welding that is located every gusset between the column nest otic placode has shelves round pin piece, and it has the reserve pinhole to open at shelves round pin piece and gusset overlap the position.

Preferably, the roof beam further comprises an inclination angle sensor, a controller and an alarm, wherein the inclination angle sensor is arranged at the top of the roof beam main body, the inclination angle sensor is connected with the input end of the controller, and the output end of the controller is connected with the alarm.

Compared with the prior art, the utility model following beneficial effect has.

On one hand, the utility model adds the spare pin hole, so that when the lug plate of the column nest is damaged, the spare pin hole can be hinged with the hinge hole of the rod head of the hydraulic telescopic stand column through the mounting pin shaft to fix the hydraulic telescopic stand column, thereby shortening the time for replacing the column nest body and improving the working efficiency; on the other hand, the utility model discloses an installation inclination sensor carries out alarm control when can approaching extreme position to the excessive low head of hydraulic support, plays the prevention guard action, reduces and avoids the emergence number of times of this problem.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 4 and 5, the utility model relates to a post socket protection and standby device, including back timber main part 5 and the post socket body 1 of welding on back timber main part 5, the both ends of post socket body 1 are equipped with gusset 10, and the both sides of post socket body 1 are provided with 2 pairs of post socket otic placodes 2, and every inboard at gusset 10 to 2 parallel arrangement of post socket otic placodes, gusset 10 and the perpendicular setting of post socket otic placode 2, and the outside welding that is located every gusset 10 between every pair of post socket otic placode has shelves round pin piece 3, and it has standby pinhole 11 to overlap the position at shelves round pin piece 3 and gusset 10.

As another embodiment, the present embodiment further includes an inclination sensor 4, a controller and an alarm, the inclination sensor 4 is disposed on the top of the top beam main body 5, the inclination sensor 4 is connected to an input end of the controller, and an output end of the controller is connected to the alarm through a relay. The inclination angle sensor 4 can adopt a model SCA60C, the alarm can adopt a rotary warning lamp, and the controller can adopt a 51-series single chip microcomputer.

As another embodiment, in order to further improve the measurement accuracy of the inclination angle, an inclination angle sensor 4 may be additionally provided on each of the base and the shield beam.

To the working process and principle of the utility model further explain: the inclination angle sensor 4 monitors the inclination angle of the top beam main body 5 in real time, the inclination angle of the top beam main body 5 relative to the base is set, and when the monitored inclination angle is larger than or equal to the set inclination angle, the alarm emits light and sounds to give an alarm. At the moment, whether the column socket ear plate 2 is broken or not is checked, if the column socket ear plate is broken, the original pin shaft is removed, the lengthened pin shaft penetrates through the spare pin hole 11 in the pin retaining block 3 and the hinge hole 9 of the rod head 8, the hydraulic telescopic stand column 6 is enabled to be propped against the column socket body 1, and the hydraulic support can be continuously and normally used.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
