Abstract
A guide rail vibration isolation structure comprises elevator guide rail fixed plates, a support steel structure, elastic vibration reduction pieces and adjusting bolts, wherein an elevator guide rail is mounted on the support steel structure through the guide rail fixed plates rather than directly fixed and mounted on a steel sectional material; the elastic vibration reduction pieces are connected with the support steel structure through the adjusting bolts and are fixed on a building structure in a lift shaft through mounting screw holes on the two sides; rigid connection between the elevator guide rail and the building structure is eliminated, as a result, solid transmission of structure vibration of the elevator guide rail is cut off; each support steel structure is provided with two elastic vibration reduction pieces, and bolt holes for the adjusting bolts are uniformly formed in the planes of the front side, left side and right side of each elastic vibration reduction piece, the perpendicularity of the elevator guide rail and parallelism between two elevator guide rails can be conveniently adjusted, and friction and vibration noise is reduced.
Description
Technical field
The present invention relates to a kind of Noise and Vibration Control transformation, the technology that the low-frequency vibration noise solid that while preventing elevator operation, guide rail cliding friction produces is propagated.
Background technology
Lift car and counterweight housing of elevator are the modes that slides of leading boots and be fixed on the cage guide of both sides with U-shaped, cage guide is fixed on elevator hoistways inner side, at present, cage guide is to use guide rail fixed plate to be fixed on steel profile, and in steel profile and hoistway, building structure is directly installed.When elevator operation, when car, counterweight frame and main guide rail move up and down, lead friction between the friction between boots (guide wheel) and cage guide, each turning unit and hoist ropes and vibration, towing machine system vibration is passed to car by hoist ropes and also all will be delivered to guide rail, " overhead speaker " that vibration forms by the rigid attachment between cage guide and building structure enters building structure, structural vibration spreads in resident family's building structure close with hoistway, forms the rest of low-frequency vibration influence of noise resident family.
Cause the reason of cage guide structural vibration to also have cage guide that situation is installed bad or use after certain phase, the requirement that the parallelism between the squareness of cage guide and two cage guides fails to meet JG/T5072.2-1996 " elevator T type guide rail inspection rule " causes friction and vibration aggravation.Because the installation of guide rail is direct fixed installation, be difficult to reach alleviation through adjusting.
The method of dealing with problems is at present, changes the U-shaped boots of leading of lift car into rolling pulley group, because rolling pulley group is by spring controlled, can reduce that elevator is operating to be contacted with rigidity with cage guide friction.But, exist following not enough: the cage guide difference 1, using due to two kinds of modes of sliding, the guide rail that assembly pulley uses is larger, relate to the series of problems such as replacing of cage guide; 2, at the express elevator of cage operation speed >=2m/s, the cage guide friction that rolling pulley group produces and vibration still exist, and cage operation speed is higher, and friction and vibration are larger, larger on the impact of resident family.
Summary of the invention
In order to overcome that low-frequency vibration noise solid that cage guide cliding friction produces is propagated and by the U-shaped deficiency of leading boots and change into rolling pulley group, the object of the present invention is to provide a kind of vibration isolation mounting structure of cage guide, barrier structure Vibration propagation approach, can effectively control cage guide transmission of vibration, remove the impact of low-frequency vibration noise on resident family.Meanwhile, can adjust the squareness of cage guide.
The technical solution adopted for the present invention to solve the technical problems is: guide rail vibration insulation structure is set and replaces the direct hard-wired steel profile of former cage guide, guide rail vibration insulation structure is made up of guide rail fixed plate, support steel structure, elastic damping part, adjustment bolt.Cage guide is arranged in support steel structure by guide rail fixed plate, and elastic damping part connects with support steel structure by adjusting bolt.Support steel structure is made up of U-shaped steel plate structure and ribbed stiffener, and ribbed stiffener is arranged between U-shaped steel plate structure front and two flank side surface.U-shaped steel plate structure front arranges the circular hole of two mounting guide rail adapter plates and two and the levels of adjusting bolts is installed to slotted hole, and U-shaped steel plate structure side respectively has one the level of adjusting bolt to be installed to slotted hole.Can allowing at oval direction adjustment bolt position of slotted hole.Two elastic damping parts of each support steel setted structure, the positive facial plane of each elastic damping part and left and right side plane all arrange adjusts the bolt hole of bolt, and elastic damping part uses hold-down bolt to be fixed in hoistway in building structure by upper and lower two mounting holes.
Elastic damping part is formed by rubber and metal composite, and surface is all rubber-coated, and its rigidity, deformation range, load scope meet the installation specification requirement of cage guide, can fix reliably cage guide.It is low that elastic damping part has natural frequency under rated load, the feature that vibration isolating effect is good.The feature of elastomeric material is to have interior friction, and critical damping is larger, can absorbing vibrational energy, and decay, intercept vibration and transmit.Adjust the squareness of building structure in cage guide and hoistway by the A bolt in turnable elastic vibration-damped component front, adjust the parallelism between squareness and two cage guides about cage guide by the B bolt of turnable elastic vibration-damped component side.
The invention has the beneficial effects as follows, eliminate being rigidly connected between cage guide and building structure, decay, iris action by elastic damping part to cage guide vibration, the impact of the low-frequency vibration noise that elimination vibration of elevator brings on resident family.Can fix reliably cage guide, the parallelism between convenient squareness and two cage guides of adjusting guide rail, reduces friction and vibration noise.
