Description

Technical Field

[0001] This utility model relates to the field of mechanical power transmission technology, specifically to a clutch device for rapid power switching. Background Technology

[0002] To achieve untwisting, a cage stranding machine needs to ensure that the pay-off reel and the cage rotate synchronously. Existing technologies typically employ a transmission structure to synchronize the pay-off reel and the cage. Examples include a synchronous belt untwisting cage stranding machine disclosed in Chinese invention publication CN107248437B, and a cage stranding machine and its untwisting system disclosed in Chinese invention publication CN106638069B.

[0003] However, for parallel cage winches, due to the presence of multiple cages, each with corresponding multiple pay-off reels, the transmission structure for synchronizing the pay-off reels with the cages becomes more complex. For different cables, the rotational speeds of each cage may need to be set to the same or different, and the rotational speeds of the corresponding pay-off reels also need to be adjusted accordingly, further complicating the operating conditions of the transmission structure. This situation requires the transmission structure to be able to adapt to power switching under multiple operating conditions.

[0004] To meet the transmission structure requirements under various working conditions, a mechanism that can quickly switch power is urgently needed. Summary of the Invention

[0005] This utility model aims to meet the above-mentioned needs of the prior art and provides a clutch device for rapid power switching, the technical solution of which is as follows.

[0006] A clutch device for rapid power switching, comprising:

[0007] The clutch box contains a coaxially arranged gear and a gear sleeve, as well as a drive mechanism that drives the gear and the gear sleeve to engage and disengage axially. The gear and the gear sleeve mesh with each other at opposite ends.

[0008] The first drive shaft has its first end coaxially connected to the gear and rotating synchronously with the gear, while its second end extends out of the clutch box.

[0009] The second drive shaft has its first end coaxially connected to the gear sleeve and rotates synchronously with the gear sleeve, and its second end also passes out of the clutch box.

[0010] The first pulley and the second pulley are coaxially fixed to the second end of the first drive shaft;

[0011] The third and fourth pulleys are coaxially fixed to the second end of the second drive shaft.

[0012] In one improvement, the clutch housing has a first support seat for rotational engagement with a first drive shaft and a second support seat for rotational engagement with a second drive shaft.

[0013] In another improvement, the gear is connected to the first end of the first drive shaft via a keyway structure to form a rotational synchronous engagement, and the gear can slide axially along the first end of the first drive shaft.

[0014] Furthermore, the gear has a circumferentially arranged annular groove, and the drive mechanism is a shift fork that fits in the annular groove. The shift fork has a handle that extends radially out of the gearbox, and the gearbox has an elongated hole for the handle to move parallel to the axial direction of the gear.

[0015] Furthermore, the clutch housing is equipped with a guide rail parallel to the gear axis, and the handle and the guide rail form a sliding pair.

[0016] In another improvement, the first drive shaft includes a first shaft and a second shaft that are coaxially aligned, and a coupling for connecting the first shaft and the second shaft to each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By using gears and gear sleeves to engage and disengage the first and second drive shafts, the first and second drive shafts can either share the same power source to drive one load or drive two loads simultaneously, or they can use different power sources to drive two loads separately. This can be used in parallel cage winches to meet the transmission structure requirements of multiple working conditions.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0021] Please see Figure 1 As shown, in one embodiment, the present invention provides a clutch device for rapid power switching, the structure of which includes:

[0022] The clutch box 1 has a coaxially arranged gear 2 and gear sleeve 3 inside, as well as a drive mechanism 4 that drives the gear 2 and gear sleeve 3 to engage and disengage axially. The gear 2 and gear sleeve 3 mesh with each other at their opposite ends. For example, the gear 2 is a bevel gear, conical gear, or crown gear with its tooth surface facing the gear sleeve 3, and the end of the gear sleeve 3 facing the gear 2 is set to mesh exactly with the tooth surface of the gear 2.

[0023] The first drive shaft 5 has its first end coaxially connected to the gear 2 and rotates synchronously with the gear 2, while its second end extends out of the clutch box 1.

[0024] The second drive shaft 6 has its first end coaxially connected to the gear sleeve 3 and rotates synchronously with the gear sleeve 3, and its second end also passes out of the clutch box 1.

[0025] The first pulley 51 and the second pulley 52 are coaxially fixed to the second end of the first drive shaft 5;

[0026] The third pulley 61 and the fourth pulley 62 are coaxially fixed to the second end of the second transmission shaft 6.

[0027] In the above embodiment, the first pulley 51 can be connected to the first power source via belt drive, the second pulley 52 can be connected to the first load via belt drive, the third pulley 61 can be connected to the second power source via belt drive, and the fourth pulley 62 can be connected to the second load via belt drive. The first drive shaft 5 and the second drive shaft 6 are engaged and disengaged via gear 2 and gear sleeve 3, allowing the first drive shaft 5 and the second drive shaft 6 to either share the same power source to drive one load or simultaneously drive two loads, or to use different power sources to drive two loads separately.

[0028] When specifically applied to parallel cage winches, the pay-off reel and the winch can be connected to the main shaft of the system through a clutch device that allows for rapid power switching in the above embodiments, thereby meeting the transmission structure requirements under multiple working conditions.

[0029] In a preferred embodiment, the clutch housing 1 has a first support seat 11 for rotating engagement with the first drive shaft 5 and a second support seat 12 for rotating engagement with the second drive shaft 6. Specifically, it can be optionally configured such that the first drive shaft 5 is engaged with the first support seat 11 via bearings, and the second drive shaft 6 is also engaged with the second support seat 12 via bearings.

[0030] In a preferred embodiment, gear 2 is connected to the first end of the first transmission shaft 5 via a keyway structure to form a rotational synchronous engagement, and gear 2 can slide axially along the first end of the first transmission shaft 5. For example, an axially extending convex key is provided on the cylindrical surface of the first transmission shaft 5, and a groove is provided on the inner annular surface of gear 2 to engage with the convex key; the convex key and the groove slide in axial engagement along the first transmission shaft 5. Alternatively, an axially extending groove can be provided on the cylindrical surface of the first transmission shaft 5, and a convex key with a matching groove can be provided on the inner annular surface of gear 2. In fact, the keyway structure is a conventional technical solution in this field, and therefore will not be described in detail with reference to the drawings.

[0031] In a preferred embodiment, the gear 2 has a circumferentially arranged annular groove 21, and the drive mechanism 4 is a shift fork 7 that fits in the annular groove 21. The shift fork 7 has a handle 71 that extends radially out of the gearbox of the gear 2, and the gearbox of the gear 2 has an elongated hole (not shown) for the handle 71 to move parallel to the axial direction of the gear 2. Therefore, pushing the handle 71 along the axial direction of the gear 2 can drive the gear 2 to move axially, thereby realizing the engagement and disengagement of the gear 2 and the gear sleeve 3, and further realizing the engagement and disengagement of the first drive shaft 5 and the second drive shaft 6.

[0032] Furthermore, the clutch box 1 is provided with a guide rail 13 parallel to the axis of the gear 2, and the handle 71 and the guide rail 13 form a sliding pair.

[0033] In a preferred embodiment, the first drive shaft 5 includes a first shaft 5a and a second shaft 5b coaxially aligned, and a coupling 53 for connecting the first shaft 5a and the second shaft 5b to each other. A first pulley 51 and a second pulley 52 are disposed on the first shaft 5a, and the second end of the first drive shaft 5 is disposed on the second shaft 5b. The first shaft 5a and the second shaft 5b are connected by the coupling 53, giving the first drive shaft 5 a detachable split structure, which facilitates assembly and maintenance.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
