Abstract
The utility model discloses a spring conical surface stopper, including the casing, have one section external screw thread the transmission shaft, set up in transmission shaft outband screw thread section and have internal screw thread gear, conical surface friction disk, ratchet, still include driving sleeve, spring, the driving sleeve sets up on the transmission shaft, the spring set up on the transmission shaft and with transmission shaft liner connection. Wherein, gear and rotation axis connection to be located that section of axis of rotation outband screw thread, transmission shaft and transmission shaft liner connection, the driving sleeve is connected with conical surface friction disk. When the spring application driving sleeve, conical surface friction disk compresses tightly production frictional force with the friction surface that corresponds simultaneously to reach the effect of braking. Start or during the time -out at power, through the relative motion of transmission shaft and gear, the horizontal migration of realization gear steps up or loosens the ratchet to reach the mesh of auto -lock or unblock.
Description
technical field:
The utility model relates to spring and loads and adopt mechanical device to carry out the mechanical braking field of folding, is specifically related to a kind of spring conical surface break.
background technique:
At present, during existing winch manual brake work, be divided into two class modes of braking: first kind break be directly installed on speed reducer and motor to wheel outer rim, during this brake operation, completely by manual operation, it is comparatively large to there is braking moment in it, and labor intensity is large, the shortcoming that manipulator's physical output is large.
Another kind of break utilizes hydraulic pressure, motor to drive Non-follow control, and it is longer that it has the hydraulic control reaction time, and drive and control of electric machine Safety performance requires the shortcomings such as high.
Model utility content
For above problem, the utility model provides a kind of structure simple, easy to operate spring conical surface break.
In order to solve the problems of the technologies described above, the technological scheme of employing is as follows: a kind of spring conical surface break, comprises casing, with one section of externally threaded transmission shaft, is arranged on transmission shaft band external thread section and is with female gear, conical surface friction dish, ratchet; It is characterized in that, also comprise driving sleeve, spring; Described driving sleeve is arranged on transmission shaft, and described spring to be arranged on transmission shaft and to be connected with driving sleeve.
The beneficial effect of this programme: 1, structure is simple: in the technical program, gear is connected with rotatingshaft, and transmission shaft is connected with driving sleeve, and driving sleeve is connected with conical surface friction dish.When spring compression driving sleeve, conical surface friction dish and corresponding rubbing surface compress and produce frictional force simultaneously, thus reach the effect of braking.2, easy to operate: only to need the effect regulating the position of driving sleeve just can reach braking or open, by with one section of externally threaded transmission shaft with to be arranged on transmission shaft band external thread section and to be with female gear, at dynamic start or when suspending, by the relative movement of transmission shaft and gear, realize gear move horizontally step up or unclamp ratchet, thus reach the object of self-locking or unblock.
Above scheme is base case of the present utility model.
Preferred version 1, as the improvement to base case, described conical surface friction dish is arranged on driving sleeve, and the shape at the friction position of conical surface friction dish is taper.Advantage is, rubbing surface is arranged to the conical surface, can increase pressure, thus improving frictional force, making braking effect better when compressing.
Preferred version 2, as the improvement to base case, also comprises pushing shaft, promotes axle sleeve, bearing, after described pushing shaft is arranged on transmission shaft, pushing shaft establishes outside thread; The internal thread that described bearing settlement matches with outside thread on pushing shaft.Advantage is, by arranging the mode of screw thread, realizes the Horizontal displacement of pushing shaft, and structure is simple, easy to operate.
Preferred version 3, as the improvement to preferred version 2, described pushing shaft also arranges handle, and advantage is, increases moment of rotation during operation, simple to operate, laborsaving.
Preferred version 4, as the improvement to preferred version 2, described pushing shaft is sheathed on pushing shaft, promotes axle sleeve one end and to limit the flange of position.Advantage is, is promoted to leave corresponding rubbing surface by conical surface friction dish, avoids actuating length excessive, and spring pressure is excessive causes handle revolution to damage people.
Preferred version 5, as the improvement to base case, described driving sleeve and the Placement of transmission shaft are that key is connected.The part that key connects and axle can also slide along axle while turning, and structure is simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
For making content of the present utility model more become apparent, be described further below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, when needs lifting heavy, forward swinging handle 9(sets forward swinging handle, pushing shaft is to left movement), the outside thread of pushing shaft 8 and the screw-internal thread fit of bearing 202 make pushing shaft 8 be moved to the left, and drive the promotion axle sleeve 7 be located on pushing shaft to be synchronously moved to the left simultaneously, promote axle sleeve 7 and promote friction disk 5 and driving sleeve 6 synchronizing moving left, friction disk 5 leaves friction plate 11, simultaneously holddown spring 4.Start power, when power drives transmission shaft 1 to rotate, gear 10 is reversed instantaneously by the reaction force of load and moves axially compression ratchet 3, and transmission shaft 1 and gear 10 are that key is connected, thus driven gear 10 rotates, thus lifting heavy.
When promoting in-position and needing to stop, reverse swinging handle 9, the outside thread of pushing shaft 8 and the screw-internal thread fit of bearing 202 make pushing shaft 8 move right, drive the promotion axle sleeve 7 be located on pushing shaft synchronously to move right simultaneously, due to the elastic force of spring 4, friction disk 5 and driving sleeve 6 synchronizing moving to the right, friction disk 5 pressing friction sheet 11, thus reach the object of braking.Meanwhile, because gear 10 and ratchet 3 are locked, ratchet 3 is hinged with ratchet, and braking system self-locking can not be reversed.
When load needs to fall, forward swinging handle 9, the outside thread of pushing shaft 8 and the screw-internal thread fit of bearing 202 make pushing shaft 8 be moved to the left, drive the promotion axle sleeve 7 be located on pushing shaft to be synchronously moved to the left simultaneously, promote axle sleeve 7 and promote friction disk 5 and driving sleeve 6 synchronizing moving left, friction disk 5 leaves friction plate 11, simultaneously holddown spring 4.Start power, power drives transmission shaft 1 to reverse, and gear 10 rotates forward to move axially instantaneously and leaves ratchet 3.Gear 10 is subject to the double reaction plus of load and braking system and reverses, and load can fall.
When load whereabouts intermediate demand aloft stops again, only need cut off power, braking system produces self-locking again immediately, and load can aloft stop.
When needs zero load is fallen, power drives transmission shaft 1 to reverse, and transmission shaft 1 is reversed by driven gear 10, can zero load fall.
