A kind of car sheave device
Technical field:
The utility model relates to the elevator technology field, relates in particular to a kind of car sheave device.
Background technology:
Elevator be a kind of be the vertical conveyor of power with the electrical motor, case shape gondola is housed, be used for tier building and take advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment in skyscraper and public place and indispensable.The development of Along with computer technology, automatic technology and Power Electronic Technique, modem elevator have become the representative type electromechanical integrated product.Raising along with whole national economy strength; The people's personal consumption level rises appreciably; The real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth point in whole elevator market.
Existing elevator, its car fag end assembly is installed on sedan-chair frame crossbeam, and its mounting structure is generally the fixed installation formula, as not installing angle when installing, then influences the normal operation of elevator, also can increase noise in addition.
The utility model content:
The purpose of the utility model is to the deficiency of prior art a kind of car sheave device to be provided, and they can 360 ° of rotational automatic adjusting angles, and can effectively reduce noise.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of car sheave device; It comprises car sheave assembly and sedan-chair frame crossbeam, and the car sheave assembly is arranged at said sedan-chair frame crossbeam, and it also comprises screw rod, nut and rubber; Said screw rod wears said rubber after passing car sheave assembly and sedan-chair frame crossbeam again, and nut locking is connected in the screw rod bottom.
Said rubber top is provided with U type bending plate, and the rubber bottom is provided with shrouding, and said screw rod wears said U type bending plate, rubber and said shrouding, and U type bending plate holds out against said sedan-chair frame crossbeam, and nut holds out against said shrouding.
The bottom of said screw rod is provided with the anticreep latch.
The car sheave assembly is provided with the small rubber piece, and said screw rod wears this small rubber piece.
The utility model beneficial effect is:
The described a kind of car sheave device of the utility model; It comprises car sheave assembly and sedan-chair frame crossbeam, and the car sheave assembly is arranged at said sedan-chair frame crossbeam, and it also comprises screw rod, nut and rubber; Said screw rod wears said rubber after passing car sheave assembly and sedan-chair frame crossbeam again; Nut locking is connected in the screw rod bottom, and they can 360 ° of rotational automatic adjusting angles, and can effectively reduce noise.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1; The described a kind of car sheave device of the utility model, its structure are that it comprises car sheave assembly 1 and sedan-chair frame crossbeam 2; Car sheave assembly 1 is arranged at said sedan-chair frame crossbeam 2; It also comprises screw rod 4, nut 7 and rubber 5, and said screw rod 4 wears said rubber 5 after passing car sheave assembly 1 and sedan-chair frame crossbeam 2 again, and nut 7 lockings are connected in screw rod 4 bottoms.
Be provided with U type bending plate 3 as said rubber 5 tops preferred embodiment; Rubber 5 bottoms are provided with shrouding 6; Said screw rod 4 wears said U type bending plate, rubber 5 and said shrouding 6, and U type bending plate holds out against said sedan-chair frame crossbeam 2, and nut 7 holds out against said shrouding 6; U type bending plate can play the effect of reinforcement, and shrouding 6 can play the effect that attaching nut 7 is locked.Further, the bottom of said screw rod 4 is provided with anticreep latch 8, can prevent effectively that nut 7 from coming off and the potential safety hazard that causes.Further, car sheave assembly 1 is provided with small rubber piece 9, and said screw rod 4 wears this small rubber piece 9, and this small rubber piece 9 can reduce the friction between screw rod 4 and the car sheave assembly 1 and reduce noise.
The said a kind of car sheave device of the utility model, car sheave assembly 1 can be through 4360 ° of ground of screw rod rotary setting on sedan-chair frame crossbeam 2, and in addition, rubber 5 can play the effect of reducing friction and reducing noise.Therefore, the utlity model has can 360 ° of rotational automatic adjusting angles, and can effectively reduce the advantage of noise, have guaranteed the normal operation of elevator.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
