Abstract
The utility model relates to a heavy damping scour protection energy -absorbing hydraulic support belongs to the colliery and struts the field, especially is applied to the deep mine and has among the rock burst sideway tunnel advance support. The utility model discloses having the rigidity and strutting the double grading of ability and the flexible energy -absorbing of stepping down, can provide sufficient setting load and working resistance promptly under the quasi -static loading condition, under moving carrier strip spare, strong magnet (neodymium iron boron) and energy -absorbing member (the arris pipe is rolled over to bent shell) in the support are had an effect immediately, realize stepping down fast and the absorbing effect through failure deformation, can resist and cushion the major part and assault kinetic energy to the stability of assurance personnel safety and equipment. The technical scheme of its solution is, two strong magnets are arranged the upper and lower both ends of energy -absorbing component in respectively to the mutual exclusion nature of application strong magnet and the plasticity of energy -absorbing component, the utility model discloses strengthened hydraulic support's damping coefficient, the adaptation has rock burst's region, can crush by the effective control, and the security performance is high.
Description
Technical field
This utility model relates to bump mine support equipment, particularly relates to a kind of heavy damping erosion control energy-absorbing hydraulic support.
Background technology
At present, along with coal resources in China develops to deep, the bump generation frequency is also come more many, and disaster is increasingly severe situation, causes great threat to the life security of Safety of Coal Mine Production and vast Coal Mine Staff. Bump is one of disaster threatening mineral industry production safety in the whole world, once occur, support damage, side fall roof, tunnel blocking can be caused, injure personnel, cause workmen to be injured by a crashing object, traumatic injury, squeeze wound, even owing to tunnel blocks death by suffocation, therefore, the preventing and treating of bump is always up the global problem that underground mining faces.
Conventional hydraulic support produces support force mainly by fluid pressure and realizes automatically moving setting a kind of hydraulic power unit carrying out roof timbering and management, main material aspect and hydraulic support electrohydraulic control technology aspect to stent structural members has carried out the research of high intensity, want to utilize high rigidity support system to resist bump, but the restriction based on technology, the support apparatus of high especially rigidity can not be built, and the equipment cost of high rigidity is relatively big, economic benefit is low. Utilize high rigidity support system can only unilaterally solve roadway support and strengthen degree, when the smaller fashion of the impulsive force of bump can be resisted and cushion, it is unlikely to damage hydraulic support, but, when bigger bump can not effectively resists and cushion temporarily, cause roadway deformation amount big, more it cannot be guaranteed that the safety of staff and equipment.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is exactly provide a kind of heavy damping erosion control energy-absorbing hydraulic support for bump mine, hydraulic support damped coefficient can be effectively improved, abandon the support system improving rigidity simply, enhanced erosion control energy-absorbing effect, resisted and buffered big bump, greatly reduce roadway deformation amount, thus ensureing the safety of staff and equipment.
The technical scheme that this utility model solves is, including pillar, strong magnet and energy absorbing members, at lower rod end equipped with a pair strong magnet and energy absorbing members, utilize the same sex mutual exclusion principle of Magnet, by the one side opposite of strong magnet identical polar, energy absorbing members is clamped by two pieces of strong magnet annulus, and one of strong magnet is hinged with lower rod end, another block and base upper end thereof, energy absorbing members is also hinged with strong magnet.
In this utility model, strong magnet is that the ndfeb magnet with high magnetic is made, and energy absorbing members is that the moulding element with higher-strength is made, and its thin-wall metal pipe being filled with porous foam alloy material is made, and thin-wall metal pipe is bent shell folding rib pipe.
This utility model enhances the damping energy dissipation mechanism of hydraulic support greatly, add the erosion control energy-absorbing effect of hydraulic support, economical and practical, safe and reliable, for having, effect in the lame advanced supporting of bump tendency is better, effectively can sink by controlroof, be greatly improved security performance, it is ensured that the safety of staff and equipment.

In figure, 1 base, 2 pillars, 3 back timbers, 4 caving shields, 5 push units, 6 linkages, 7 strong magnets, 8 energy absorbing members.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Be can be seen that by Fig. 1-2, this utility model includes base 1, pillar 2, back timber 3, strong magnet 7 and energy absorbing members 8, base 1 pillar 2 installed above, in pillar 2 lower end equipped with a pair strong magnet 7 and energy absorbing members 8, energy absorbing members is clamped by two pieces of strong magnet annulus, and one of strong magnet and lower rod end are hinged, another block and base upper end thereof, energy absorbing members is also hinged with strong magnet, forms the meat clip Mo structure.
Described strong magnet 7 has four pairs, and energy absorbing members 8 has four, is attached separately on corresponding hydraulic prop 2.
For ensureing result of use, strong magnet 7 is that the ndfeb magnet with high magnetic is made.
Described strong magnet 7 is the same sex mutual exclusion principle utilizing Magnet, so by the one side opposite of strong magnet 7 identical polar, when energy absorbing members pressurized, the magnetic that strong magnet 7 produces increases, and can resist external bump.
Described a kind of heavy damping erosion control energy-absorbing hydraulic support, is characterized in that, described energy absorbing members 8 is that the moulding element with higher-strength is made, and its thin-wall metal pipe being filled with porous foam alloy material is made, and thin-wall metal pipe is bent shell folding rib pipe.
Move towards to install along tunnel when support is installed, according to underworkings actual height, select the hydraulic support of proper height, and carry out protective measure.
This utility model enhances the damping energy dissipation mechanism of hydraulic support greatly, add the erosion control energy-absorbing effect of hydraulic support, economical and practical, safe and reliable, for having, effect in the lame advanced supporting of bump tendency is better, effectively can sink by controlroof, be greatly improved security performance, it is ensured that the safety of staff and equipment.
After using this utility model in tunnel, when quasi-static loading, the pressure of roadway surrounding rock can pass through pillar 2 and pass to strong magnet 7 and energy absorbing members 8, thus providing enough setting loads and working resistance.
When there is bump; after the pressure that strong magnet 7 and energy absorbing members 8 bear exceedes its threshold values; then energy absorbing members 8 can destroy immediately and carry out energy-absorbing and step down; and then the magnetic force that strong magnet 7 produces increases as well as the compression of energy absorbing members 8; thus resisting and buffered big impact kinetic energy; make the state that the maintenance of hydraulic support entirety is stable, reach the safety of protection staff and equipment.
This utility model is not limited to above-mentioned hydraulic support; it is applicable to most hydraulic support, and any conspicuously improved or change that this utility model is done is all without the protection domain exceeding this utility model claims only illustrated by way of example.
