Description
Technical field
The utility model relates to a kind of elevator technology field, particularly relates to that a kind of structure is simple, the car loading and unloading shock absorber of good damping result.
Background technology
Elevator is driven by motor, between floors the device of vertical passenger-carrying or goods.Along with being on the increase of skyscraper, the elevator of large hoisting depth is applied to the building in each field more and more.Car is elevator in order to the box-shaped space of carrying and transport personnel and goods and materials, and personnel and goods and materials pass in and out car by elevator door.If Steel belt elevator system is under higher hoisting depth, when car is positioned at lower floor, in loading and unloading process, the changes in weight of car causes it to produce vibration at vertical direction, and larger position skew is produced when loading moment and static state, the skew of this position even may cause accident to occur.In the steel rope elevator device of large hoisting depth, this problem exists equally.Elevator has story-leveling function again, and lift crosshead is equipped with some photoelectric switchs, near door district, be provided with reflector, and when exceeding the certain threshold value of flat bed scope because of any reason after Elevator landing, main frame can declutch and change moment and make elevator get back to level position.
Steel belt elevator system as domestic at present has employing HoverMode to solve this problem, this technology is at lift car leveling, after gate is opened completely, main frame is declutched, main frame is by the continuous weighting device reading control torque on steel band, thus the vibration damping that car is produced when loading and unloading fast as far as possible, and finally reach quiescence.But this mode also existing defects, the problem of car sinking (or during unloading, car being jumped) when adopting the elevator device of HoverMode to still have client feedback to load in actual use, thinks that this human discomfort has exceeded its tolerance.The principle of HoverMode determines it and cannot solve power and transmit in steel band and cause continuous weighting device reading and car acceleration on steel band to there is the problem necessarily postponed, it is delayed that this makes control system exist, and still can not be well controlled at the acceleration/accel of loading and unloading moment car.Secondly, due to the requirement of standard, HoverMode just can only start after gate is opened completely, therefore if any loading and unloading in door opening process, now HoverMode inoperative, and the vibration of car and position offset still serious.
Summary of the invention

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
A kind of car loading and unloading of the present embodiment shock absorber, as shown in Figure 1, the clamping device including support 2, damping mechanism and guide rail is clamped.
Support 2 is C type, and the bottom of support is fixed on car upper beam 1, and damping mechanism and clamping device are positioned at the inside of support, and damping mechanism has damper rod 9, and damper rod is arranged upward, and damper rod upper end is fixed on frame upper bottom surface.
Damping mechanism also includes erecting frame, damper 8, erecting frame includes base plate 4, base plate is fixed on clamping device, base plate is vertically fixed with stay bearing plate 5, be provided with connecting panel 6 on the supporting plate, connecting panel is L-type, and connecting panel one side is fixed with stay bearing plate, and damper is fixed on connecting panel another side by fixed block 7.Fixed block is provided with through hole, and damper to be inserted in through hole and to be bolted, and fixed block is also provided with some bolts hole, is provided with bolt and is fixed on connecting panel by fixed block in bolt hole.
As shown in Figure 2, clamping device comprises base 21, and base bilateral symmetry is provided with clamping limb 10, and clamping limb middle part is connected with base rotation by the first rotating shaft 14, two clamping limb front ends lay respectively in guide rail both sides, and relative side, the front end of two clamping limbs is all provided with brake plate 20 respectively.Two clamping limb back segments are connected with swing arm 11 separately by the first bearing pin 15, swing arm middle part is rotatably connected on base 21 by the second rotating shaft 16, the other end of two swing arms is connected on the front end of stretching arm 12 by the second bearing pin 17, stretching arm rear end and cylinders.Stretching arm bottom surface is provided with spacing straight trough 18 along length, and on base, correspondence is provided with limited post 19, and limited post is inserted in spacing straight trough.
In normal state, after lift car leveling, clamping device clamps guide rail, and its Clamping force is enough to ensure that car and guide rail can not relative motions.When having people or goods enters car, car has downswing, and damper rod is compressed by support, provides larger damping during compression, and the amplitude of car vibrations is reduced, and vibration rapidly decays to static.The antagonistic force that damper provides in quiescence is very little, thus when personnel enter to more than a threshold value, then story-leveling function is triggered, lift car gets back to level position, and damper rod also gets back to initial position.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as upper beam, support, guide rail, base plate, stay bearing plate herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
