Abstract
The utility model discloses a vibration damper for a traction machine. The vibration damper for the traction machine comprises the traction machine, a rope gripper, a bearing beam, a beam, damping springs, a bolt and bases, wherein the traction machine and the rope gripper are fixedly arranged on the bearing beam; the bearing beam is arranged on the beam; a damping spring III is arranged between the bearing beam and the beam on the lower part of the traction machine, and a base II is fixedly arranged at the position of the damping spring III on the lower part of the beam; mounting holes are formed in a bearing beam end and a beam end in the direction of the rope gripper respectively; the bolt is fixedly connected with a base I after penetrating through the bearing beam and the beam; a damping spring I is arranged on the rod part of the bolt between the bearing beam and the beam; a damping spring II is arranged on the rod part of the bolt between the beam and the base I; and the bases I and the base II are fixedly arranged on the ground. After the vibration damper for the traction machine is arranged, the upward and downward vibration of the traction machine can be positively and negatively compensated through the distal damping springs I and II, so that a vibration damping effect is ensured, and meanwhile, influence on the use of the rope gripper is avoided.
Description
Technical field
The utility model relates to elevator cushion technique field, refers to a kind of towing machine bumper especially.
Background technology
For traditional elevator, all must use velocity limiter to monitor and control the descending hypervelocity of car at any time, but the up hypervelocity of car and the danger of rushing to summit also exist really, when its reason is car zero load or minimum load, the counterweight amount of stressing is greater than car, in case misfunctioning of brake or machine shaft, key, pin etc. fracture, or because traction sheave grooving severe wear causes hoist ropes to skid therein.According to stipulating among the GB7588-2003; tracking-driven elevator should be installed protection device for over-speed ascending; this device comprises speed monitoring and deceleration assembly; should be able to detect the runaway speed of up car; when car speed during more than or equal to rated speed of lift 115%; should be able to make the car stop, or make its speed drop to the permission range of use of counterweight buffer at least.This device should act on car, counterweight, steel rope system or the traction sheave, when this device action, should make electric safety device action or control circuit dead electricity, and motor shuts down, drg action, i.e. wire holder.For reaching the operating needs of wire holder, generally all be that towing machine and wire holder are fixed on the mounting seat, so noise pass to indoor easily by structure-borne sound transmission.In elevator(lift) machine room being carried out the damping construction or transforming, generally all be under mounting seat, to increase damping spring, but because the operating needs of wire holder, the vibrations distortion that allows is less, this conflicts mutually with the raising of damping effect, and the use that therefore improves damping effect and do not influence simultaneously wire holder just becomes the technical barrier that needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is to provide a kind of remote protecting device, when guaranteeing damping effect, reduces the vibrations of base, thereby does not influence the use of wire holder.
For realizing the purpose of this utility model, intend by the following technical solutions:
The towing machine bumper, towing machine, wire holder, bearing beam, crossbeam, damping spring, bolt and base have been comprised, towing machine and wire holder all are fixedly mounted on the bearing beam, it is characterized in that: described bearing beam is installed on the crossbeam, and between the bearing beam of towing machine bottom and crossbeam, damping spring three being set, the crossbeam bottom of damping spring three positions sets firmly base two; Load-bearing beam-ends and the crossbeam end of described wire holder direction are provided with mounting hole, bolt is captiveed joint with base one after passing bearing beam and crossbeam, on the bolt shank between bearing beam and the crossbeam, be provided with damping spring one, and on the bolt shank between crossbeam and the base one, be provided with damping spring two; Described base one and base two set firmly on the ground.
Compared with prior art, the utility model installs a crossbeam additional under bearing beam, and at the crossbeam of towing machine far-end two damping springs are installed up and down, the towing machine vertical tremor can carry out positive and negative compensation by two damping springs of far-end, thereby make that whole vibrations are less, when guaranteeing damping effect, do not influence the use of wire holder.
Description of drawings
Fig. 1 is the constructional drawing of the utility model embodiment.
Label among the figure is: 1, towing machine; 2, wire holder; 3, bolt; 4, bearing beam; 5, crossbeam; 61, damping spring one; 62, damping spring two; 63, damping spring three; 71, base one; 72, base two; 8, ground.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model embodiment has comprised towing machine 1, wire holder 2, bolt 3, bearing beam 4, crossbeam 5, damping spring 1, damping spring 2 62, damping spring 3 63, base 1, base 2 72, towing machine 1 and wire holder 2 all are fixedly mounted on the bearing beam 4, bearing beam 4 is installed on the crossbeam 5, and between the bearing beam 4 of towing machine 1 bottom and crossbeam 5, damping spring 3 63 being set, crossbeam 5 bottoms of damping spring 3 63 positions set firmly base 2 72; Bearing beam 4 ends and crossbeam 5 ends of wire holder 2 directions are provided with mounting hole (not marking among the figure), bolt 3 passes bearing beam 4 captives joint with base 1 with crossbeam 5 backs, in the bolt 3 bar portions between bearing beam 4 and the crossbeam 5, be provided with damping spring 1, and in the bolt 3 bar portions between crossbeam 5 and the base 1, be provided with damping spring 2 62; Base 1 and base 2 72 set firmly on the ground.Towing machine 1 is in operation and when braking, vertical tremor, but carry out positive and negative compensation by damping spring 1 and the damping spring 2 62 that is arranged on far-end, and make that whole vibrations are less, when guaranteeing damping effect, do not influence the use of wire holder.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
