Description

Technical Field

[0001] This invention belongs to the technical field of coal mine underground mining support equipment, and in particular relates to an energy-absorbing, anti-impact, and anti-collapse hydraulic support for roadways. Background Technology

[0002] As a crucial component of the mine production system, roadways serve multiple functions, including transportation, ventilation, and pedestrian access. The strength of roadway support directly impacts the efficiency of underground coal mining and the safety of miners. With the rapid development of coal mining in my country, mines are gradually being excavated to deeper depths, leading to an increasingly higher frequency of rockbursts.

[0003] Rockbursts mostly occur in areas such as roadway support pressure zones and mining faces. According to more than 2,500 recorded destructive rockbursts in my country, roadway rockbursts account for about 86.8% of the total number of rockbursts. The cause is that the strain energy accumulated in the rock mass is suddenly released, causing brittle fracture of the rock mass, resulting in large-scale roof collapse of the roadway. The sides of the roadway also shrink inward in large quantities, affecting the normal use of underground mining equipment. Therefore, roadway support has become an important issue.

[0004] However, the hydraulic supports currently used for roadway impact protection mainly include unit-type hydraulic supports, self-moving hydraulic supports, stack-type hydraulic supports, gantry-type hydraulic supports, and hydraulic canopy supports. Because these supports are relatively high in height and have relatively small base areas, they are generally unable to maintain stability when subjected to lateral impact forces and vibrations during rock bursts. This can lead to twisting, tilting, or collapse of unit-type hydraulic supports, affecting normal production operations and potentially causing serious economic losses.

[0005] In addition, when hydraulic supports are subjected to lateral forces due to impact pressure, the hydraulic column is very likely to tilt relative to the base, causing the hydraulic column to lose its original support strength, which in turn can lead to the collapse of the roadway or damage to the hydraulic support, seriously threatening the life safety of underground workers and the normal use of support equipment. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides an energy-absorbing, anti-impact, and anti-collapse hydraulic support for roadways, which has excellent anti-impact performance, can effectively resist lateral forces, and provides effective protection for the advanced support of roadways.

[0038] The following describes a single use of the present invention with reference to the accompanying drawings:

[0039] When the hydraulic support is working normally, the telescopic support legs of the anti-tipping component 5 are in the retracted state, the lower end of the lower support leg 16 rests against the upper surface of the base 3, and the push rod 13 is inserted to its maximum depth into the locking hole of the electromagnetic lock 12. The sandwich-structured energy-absorbing component 6 can provide good support capacity under static load.

[0040] When a ground impact occurs, the hydraulic column 2 is prone to tilting. The tilt angle of the hydraulic column 2 is monitored in real time by a gyroscope. Once the tilt angle of the hydraulic column 2 exceeds the warning value, the intelligent controller will send a start signal to the electromagnetic lock 12 immediately. After receiving the start signal, the electromagnetic lock 12 will quickly control its locking tongue to retract, so that the locking tongue is disengaged from the slot 19, thereby releasing the push rod 13 from locking.

[0041] When push rod 13 is unlocked, the first thrust spring 14, through the release of its spring force, will quickly push push rod 13 outward, thereby causing the upper support leg 15 to swing outward around the hinge axis on the support 10 until the upper support leg 15 abuts against the limiting baffle 18. At the same time, as the upper support leg 15 swings, the lower end of the lower support leg 16 will disengage from the restriction of the upper surface of the base 3. The second thrust spring 17, through the release of its spring force, will quickly push the lower support leg 16 outward until the locking block 21 moves to the location of the locking hole 22. At this time, under the spring force of the locking block pushing spring 23, the locking block 21 will quickly enter the locking hole 22 from the locking block storage groove 24, thereby achieving the limiting of the lower support leg 16.

[0042] After the telescopic support legs of the two sets of anti-tipping components 5 have completed their swing extension, they can cooperate with the auxiliary support frame 4 to form effective lateral support, thereby preventing the hydraulic support from tilting or tipping over under lateral force and ensuring the reliability of the support.

[0043] During underground inspections, workers need to right tilted hydraulic supports. During this process, the tilt angle of the hydraulic column 2, monitored by the gyroscope, quickly falls below the warning value. At this point, the intelligent controller immediately sends a start signal to the locking block reset electromagnet 35. The electromagnet 35 generates a magnetic force, pulling the locking block 21 back into the locking block storage groove 24. The locking block 21 disengages from the locking hole 22, and the lower outrigger 16 is released from its limit position. Subsequently, the intelligent controller sends a start signal to the lower outrigger reset drive cylinder 34. The lower outrigger reset drive cylinder 34 retracts and exerts a pulling force on the lower outrigger 16 until the lower outrigger 16 is pulled back to its initial position. The locking block reset electromagnet 35 is de-energized. Then, with the assistance of the staff, the upper outrigger 15 is pushed inward to its original position. The lower end of the lower outrigger 16 rests against the upper surface of the base 3 of the hydraulic support again. The push rod 13 returns to its maximum insertion depth in the lock hole of the electromagnetic lock 12. Finally, the intelligent controller sends a locking signal to the electromagnetic lock 12. The lock tongue of the electromagnetic lock 12 extends and locks the push rod 13 again. At the same time, the lower outrigger reset drive cylinder 34 returns to its free state, and the anti-tipping component 5 completes the reset.

[0044] When a rock burst occurs, the corrugated plate 26 within the energy-absorbing assembly 6 can quickly deform to reduce the external impact force. Furthermore, the corrugated plate 26 maintains good support during deformation, protecting the hydraulic support from damage and ensuring its normal energy absorption. The corrugated plate 26 is coated with flame-retardant rubber in all directions, completely isolating it from the outside environment. This not only prevents rust but also isolates sparks generated during the crushing process, preventing them from contacting external gas and ensuring underground fire safety.

[0045] The solutions described in the embodiments are not intended to limit the scope of patent protection of this invention. All equivalent implementations or modifications that do not depart from the scope of this invention are included in the patent scope of this case.
