Abstract
The utility model discloses an eccentric linkage device which comprises a driving shaft, a shaft sleeve, a containing space, a swivel and centrifugal blocks, wherein the driving shaft is contained by the containing space, the containing space internally comprises a plurality of grooves which are formed by the inwards-concave inner wall of the shaft sleeve, the driving shaft is fixed by the swivel which is provided with a connection part, and the connection part is connected with the centrifugal blocks through a spring. When the driving shaft rotates, under the action of centrifugal force, and the centrifugal blocks have tendencies that one ends of the centrifugal blocks are clamped into the grooves, and the shaft sleeve is enabled to rotate along with the driving shaft. When a moving object overspeeds, the speeding object is initiatively connected with a braking system by the eccentric linkage device, so that occurrence of safety accident can be avoided.
Description
Technical field
The utility model relates to a kind of eccentric continuous action device.
Background technique
In the prior art, with the equipment of certain speed operation if there is mechanical failure, the meeting quite dangerous, take at the hanging basket of building-site construction as example, hanging basket is in transportation article or personnel, if elevating system breaks down, cause hanging basket to accelerate tenesmus, although be provided with parking brake in some hanging basket, yet the time of origin of accident is extremely short, be difficult to the enough reaction time of people that is in the hanging basket, easily cause the accident, if what transport in the hanging basket is article, parking brake is useless especially, how to accomplish when hanging basket exceeds the speed limit, the elevating system of hanging basket links to each other with brake system automatically, thereby makes brake system braking hanging basket, is a problem demanding prompt solution.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of eccentric continuous action device, when the situation of hypervelocity appears in the object of motion, will the object of hypervelocity is connected with brake system, thereby avoid the generation of security incident.
For reaching this purpose, the utility model by the following technical solutions:
A kind of eccentric continuous action device comprises driving shaft; Axle sleeve, in establish the holding space that holds driving shaft, comprise many grooves that cave in and form by sleeve lining in the holding space; Turning of rigid drive shaft, turning is provided with the convergence part; The centrifugal-block that connects the convergence part by spring; When driving shaft rotates, under centrifugal action, centrifugal-block is deposited and is at one end snapped in groove and make axle sleeve follow the trend that driving shaft rotates, and there is the other end to withstand to be opened in the trend of the projection on turning in centrifugal-block.Many groove extends axially along holding space, and is evenly distributed in the holding space.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
After the utility model is implemented, when the rotating speed of driving shaft surpasses certain threshold values, because driving shaft is the convergence part fixedly, and link to each other by spring between convergence part and the centrifugal-block, under centrifugal action, centrifugal-block overcomes spring force and makes centrifugal motion, thereby make centrifugal-block one end snap in groove, the other end withstands the projection that is opened on turning, and rotates together thereby make axle sleeve follow driving shaft, if axle sleeve is connected with brake system, driving shaft is driven by the elevating system such as hanging basket, can exceed the speed limit lifting when being about to accident occur at hanging basket, the elevating system of hanging basket is braked, thereby avoid the generation of security incident.
Description of drawings
Fig. 1 is the utility model embodiment 1 overall structure schematic diagram:
Wherein: 1, driving shaft; 2, axle sleeve; 21, groove; 3, centrifugal-block; 4, turn; 41, projection; 5, convergence part; 6, spring; 7, holding space.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
Embodiment 1
Propose a kind of eccentric continuous action device, comprise driving shaft 1; Axle sleeve 2, in establish the holding space 7 that holds driving shaft 1, comprise many grooves 21 that cave in and form by axle sleeve 2 inwalls in the holding space 7; Rigid drive shaft 1 turn 4, turning 4 is provided with convergence part 5; The centrifugal-block 3 that connects convergence part 5 by spring 6; When driving shaft 1 rotates, under centrifugal action, centrifugal-block 3 is deposited and is at one end snapped in groove 21 and make axle sleeve 2 follow the trend that driving shaft 1 rotates, and there is the other end to withstand to be opened in the trend of the projection 41 on 4 of turning in centrifugal-block 3.Many groove 21 extends axially along holding space 7, and is evenly distributed in the holding space 7.
When the rotating speed of driving shaft 1 surpasses certain threshold values, because driving shaft 1 is convergence part 5 fixedly, and link to each other by spring 6 between convergence part 5 and the centrifugal-block 3, under centrifugal action, centrifugal-block 3 overcomes the elastic force of spring 6 and makes centrifugal motion, thereby make centrifugal-block 3 one ends snap in groove 21, the other end withstands and is opened in the projection 41 of turning on 4, thereby making axle sleeve 2 follow driving shaft 1 rotates together, if axle sleeve 2 is connected with brake system, make driving shaft 1 by driving such as the elevating system of hanging basket, namely can exceed the speed limit lifting when being about to accident occur at hanging basket, elevating system to hanging basket brakes, thereby avoids the generation of security incident.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and model utility design thereof, all should be encompassed within the protection domain of the present utility model.
