Description
Technical field
The present invention relates to a kind of non-return device, relate in particular to a kind of wiggling and pressing block formula non-return device capable of reversing of big load.
Background technique
Traditional non-return device roughly is divided three classes: the one, and roller star wheel type non-return device, the 2nd, friction type non-return device, the 3rd, pawl type non-return device.Wherein roller star wheel type non-return device is in order to ensure the effect of check, and structure is huge, and volume heaviness and noise are big; The friction type non-return device is prone to heating, lost efficacy because of the formed friction torque of the frictional force that adopts friction roll realizes check, and wearing and tearing are big; The pawl type non-return device is because of ratchet self structure restriction, under big load working state, is prone to the ratchet phenomenon that fractures.Except that above three kinds of typical non-return devices, present other non-return device that adopts or select the free wheel device that is similar to the non-return device function for use, using effect is all undesirable.
The compressive strength of mechanical material is flexural strength, shear strength 5-6 times.The mode of failure of analysis conventional non-return device mostly is because the crooked shear fracture that fractures and cause because of friction, and working life is short.
Summary of the invention
In order to overcome many defectives that non-return device in the existing technology exists, the invention provides a kind of simple in structure, the check moment of torsion is big, noise is little, intensity is high, reliable operation and the wiggling and pressing block formula non-return device capable of reversing that can conveniently commutate.
In order to achieve the above object, the technological scheme of the present invention's employing is: a kind of wiggling and pressing block formula non-return device capable of reversing comprises check seat, running shaft; Running shaft is located at check seat inner chamber; Its technical characterstic is to be with supporting rotor on the said running shaft, and said supporting rotor two ends are supported on check seat inner chamber by bearing, and check seat inwall is provided with at least one pressure tank; Supporting rotor is provided with at least one wiggling and pressing block, and said wiggling and pressing block is with pressure tank and cooperates or disengaged condition.
Said pressure tank is formed by connecting circular sliding surface and the transition of straight line confined planes.
Said supporting rotor cylindrical circumference is provided with at least one group of adjacent circular arc fore shaft formula swinging chute and spring eye; One end of said wiggling and pressing block is movable to embed in the circular arc fore shaft formula swinging chute, and the working surface of the wiggling and pressing block the other end is with the straight line confined planes of pressure tank and contacts or disengaged condition.
Be provided with spring in the said swinging chute, said spring and wiggling and pressing block are contact condition.
Said pressure tank and wiggling and pressing block are the evenly setting at interval of odd number more than or equal to three groups.
The two ends of said check seat are provided with the assembling seam of symmetry, on the arbitrary load seam bonnet are installed.
After adopting above technological scheme, the beneficial effect that the present invention reaches is:
1, the straight line confined planes of wiggling and pressing block of this non-return device and pressure tank is the positive pressure stress, has brought into play the mechanical property of material to greatest extent, and check power is big, and the check moment of torsion that produces during check is big, reliable operation, and safety coefficient is high, longer service life;
2, because supporting rotor is supported on check seat inner chamber by bearing, the supporting rotor running accuracy is high, and noise is little during non-return device work;
3, because the two ends of check seat are respectively equipped with the assembling seam, on the arbitrary load seam bonnet can be installed, satisfy the check requirement of both direction.
This non-return device global design compact structure, volume are little, in light weight; The swing type briquetting that adopts has changed the stress of member, has overcome because the mechanical material bending fractures and the shear fracture that causes because of friction, and bearing capacity is strong, and working stability increases substantially working life.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the sectional view of Fig. 1.
Among the figure: check seat 1, running shaft 2, bearing 3, supporting rotor 4, wiggling and pressing block 5, circular arc fore shaft formula swinging chute 6, spring eye 7, spring 8, bonnet 9, assembling seam 10, pressure tank 11, circular sliding surface 12, straight line confined planes 13.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in 2, a kind of wiggling and pressing block formula non-return device comprises check seat 1, running shaft 2, bearing 3, supporting rotor 4, wiggling and pressing block 5, circular arc fore shaft formula swinging chute 6, spring eye 7, spring 8, bonnet 9, assembling seam 10, pressure tank 11, circular sliding surface 12 and straight line confined planes 13.Check seat 1 inwall is provided with at least three pressure tanks 11 that evenly are provided with at interval, and every pressure tank 11 is fused by circular sliding surface 12 and 13 transition of straight line confined planes; Supporting rotor 4 is socketed on the running shaft 2 and places check seat 1 inner chamber; Evenly be interval with the circular arc fore shaft formula swinging chute 6 corresponding on supporting rotor 4 excircles with the pressure tank position; Every arc latched formula swinging chute one side is equipped with the spring eye 7 that places on the supporting rotor excircle; Arc latched formula swinging chute links to each other with spring eye, is provided with wiggling and pressing block 5 in every circular arc fore shaft formula swinging chute 6, and an end of wiggling and pressing block 5 is movable to embed in the circular arc fore shaft formula swinging chute 6; Be provided with spring 8 in the spring eye 7; Spring and wiggling and pressing block 5 are contact condition, and under the effect of spring, the working surface of wiggling and pressing block 5 the other ends is contact or disengaged condition with the straight line confined planes 13 of corresponding pressure tank 11; The two ends of check seat are respectively equipped with assembling seam 10, and the assembling seam symmetric arrangement at two ends bonnet 9 is installed on arbitrary assembling seam, and another assembling seam is installed on the body, but all operations of non-return device both direction.
When running shaft 2 drive supporting rotors 4 rotate counterclockwise; Wiggling and pressing block 5 one end pressuring springs 8 and in the working area of 4 of check seat 1 and supporting rotors the sense of rotation with supporting rotor 4 slide; When wiggling and pressing block 5 one ends slip in the pressure tank 11 of check seat 1, sliding to take advantage of a situation along the circular sliding surface 12 of pressure tank slides in the working area, and this moment, non-return device did not have the check effect.
When because outage or other factors cause running shaft 2 to drive when forwarding son 4 and turning clockwise; Wiggling and pressing block 5 one ends are sprung into by 8 moments of spring in the pressure tank 11 of check seat 1 and contact with straight line confined planes 13 in the pressure tank 11; Because check seat 1 is fixing; Then straight line confined planes 13 produces check moment through 5 pairs of supporting rotors of wiggling and pressing block 4, makes running shaft 2 checks, realization work protection.
Because the two ends of check seat 1 are provided with the assembling seam 10 of symplex structure, according to the operating mode needs, non-return device selects for use different direction to install, and satisfies the check effect of various workplaces.
