Description

Technical Field

[0001] The invention belongs to the technical field of winches, and in particular relates to a reliable clutch brake winch. Background Art

[0002] In existing winches, the principle of power connection or clutch achieved by the reduction assembly and the intermediate transmission shaft in the winch is: clutching is achieved by changing the meshing relationship between the sun gear and the planetary carrier or using a locating pin to fix the planetary gear ring. When switching from the disengaged state to the engaged state, the sun gear and the planetary carrier tooth side surfaces may contact and fail to engage or the locating pin may not enter the pin hole. In this case, the drum needs to be manually rotated and rotated to a certain angle to enter the meshing or positioning state, and a compression spring clutch state is used. When the elastic recovery force of the compression spring becomes smaller after long-term use, the sun gear and the planetary carrier may not be fully engaged, and the locating pin may not fully enter the pin hole, resulting in an incomplete clutch state or even disengagement. If this state is used for a long time, the meshing teeth or locating pins will inevitably be damaged, resulting in the winch being unable to be used normally. There are many types of brake devices for winches at present, including mechanical handbrake, hydraulic brake, electromagnetic brake, mechanical automatic brake, etc. The mechanical handbrake is not safe enough and is prone to accidents, while the hydraulic and electromagnetic brakes are expensive. The mechanical automatic brake is divided into spring type, star wheel needle roller type, cam type, and spring type mechanical automatic brake. The bearing capacity is not high, while the star wheel needle roller type and cam type mechanical automatic brake are not only complex in structure, but also unreliable. Therefore, it is necessary to design a reliable clutch brake winch to overcome the above difficulties. Summary of the Invention

[0003] In response to the problems in the prior art, the present invention designs a reliable clutch brake winch. The present invention drives the clutch lock module to move axially through the clutch drive module, facilitating the mutual engagement of the external spline and the second internal spline on the clutch lock module, thereby enabling the automatic control deceleration component of the clutch assembly to be connected or disconnected from the drive shaft. The clutch assembly control process is reliable and the clutch state is stable.

[0004] The invention object of the present invention is achieved through the following technical solutions: a reliable clutch brake winch, comprising a shell, a motor and a reducer assembly are respectively provided on both sides of the shell, a drum body is provided in the middle of the shell, a brake assembly is provided in the drum body, a transmission shaft is provided between the brake assembly and the reducer assembly, the reducer assembly and the drum body are meshed with each other, and when the motor drives the transmission shaft to rotate, the reducer assembly drives the drum body to rotate; a clutch assembly is provided on the side of the reducer assembly, an end cover is provided on the side of the shell, a first internal spline is provided on the end cover, and the end cover is provided with a first internal spline. A gear ring connecting plate is provided inside the cover, and a second internal spline is provided inside the gear ring connecting plate; the clutch assembly includes a clutch drive module and a clutch lock module, the clutch drive module includes a clutch drive motor, and the clutch lock module includes a clutch connecting sleeve, an external spline is provided at the end of the clutch connecting sleeve, and a clutch latch that can be radially extended and retracted relative to the clutch connecting sleeve is provided inside the clutch connecting sleeve, and the clutch latch includes latch teeth with an inclined surface; when the clutch drive motor is working, it drives the clutch connecting sleeve to move axially along the transmission shaft, and when the clutch connecting sleeve moves, the external spline and the second internal spline engage or disengage with each other.

[0005] Preferably, the clutch assembly is mounted on the end cover, and the clutch assembly also includes a clutch housing and a ring gear connecting plate. When the clutch drive motor in the clutch drive module is working, it drives the clutch lock module to move axially along the transmission shaft; the reducer assembly includes a first-stage ring gear, and the ring gear connecting plate is fixedly connected to the first-stage ring gear; a second internal spline is provided in the ring gear connecting plate, and the first internal spline and the second internal spline have the same shape and can both engage with the external spline; a bevel is provided on the side of the second internal spline close to the external spline; an annular limit groove is provided in the ring gear connecting plate, which is adjacent to the second internal spline, and the annular limit groove is provided with the back facing the external spline.

[0006] When the clutch drive motor is in operation, it drives the clutch lock module along the axial direction of the drive shaft toward the ring gear connecting plate. This causes the external splines on the clutch lock module to mesh with the second internal splines on the ring gear connecting plate, allowing the reducer assembly to drive the drum body to rotate. At the same time, the latch teeth are locked in the annular retaining groove, ensuring that the clutch assembly remains stably engaged. When the external splines and the second internal splines disengage, the clutch assembly automatically disengages.

[0007] Preferably, the clutch drive module also includes a clutch drive driving wheel, a clutch drive driven wheel, a motor mounting seat, an elastic member and a clutch drive pin; the clutch drive motor is fixed to the side of the end cover through the motor mounting seat, the output shaft of the clutch drive motor is transmission-connected to the clutch drive driving wheel, the clutch drive driving wheel and the clutch drive driven wheel are engaged with each other; the clutch housing is connected to the end cover, a boss is provided in the clutch housing, a first bearing is sleeved on the boss, and the clutch drive driven wheel is rotationally connected to the clutch housing through the first bearing.

[0008] When the clutch drive motor is working, it drives the clutch drive driving wheel to rotate. When the clutch drive driving wheel rotates, it drives the clutch drive driven wheel to engage and rotate. When the clutch drive driven wheel rotates, it drives the clutch lock module to move along the axial direction of the transmission shaft.

[0009] Preferably, the clutch lock module also includes a clutch center shaft, a clutch cam, a latch fixing sleeve, a clutch lock spring, a center bearing and a bearing retaining ring; the clutch latch and the clutch lock spring are arranged in pairs on both sides of the clutch cam, the two clutch latches are symmetrically arranged up and down, and the two clutch lock springs are symmetrically arranged up and down; the clutch center shaft is installed in the clutch connecting sleeve through the center bearing, the latch fixing sleeve is installed in the clutch connecting sleeve, a clutch cam is provided in the latch fixing sleeve, the clutch cam sleeve is installed on the clutch center shaft, and the clutch lock spring sleeve is installed on the clutch latch; when the clutch cam rotates, it drives the clutch latch to move radially along the clutch connecting sleeve.

[0010] When the clutch center shaft rotates, it drives the clutch cam to rotate. When the clutch cam rotates, it drives the clutch latch to move along the radial direction of the clutch connecting sleeve. The two clutch latches approach each other. At this time, the clutch lock spring is in a compressed state; when the clutch center shaft disengages from the inner wall of the clutch drive driven wheel, the clutch lock spring automatically resets, so that the clutch latches move away from each other.

[0011] Preferably, the end of the clutch connecting sleeve facing the ring gear connecting plate is provided with an external spline, and a first cylindrical cylinder and a second cylindrical cylinder are respectively provided on both sides of the external spline of the clutch connecting sleeve; a spiral groove is provided on the outer layer of the first cylindrical cylinder, and the spiral groove includes a slope section and a flat slope section, and the flat slope section is arranged away from the external spline; a limit strip is provided on the inner wall of the first cylindrical cylinder along the axial direction of the clutch connecting sleeve, and the limit strip is close to the end face of the first cylindrical cylinder; a latch guide hole for inserting the clutch latch is provided on the second cylindrical cylinder, and the latch guide holes are arranged in pairs and correspond one to one with the clutch latch; a latch limiting column is provided in the second cylindrical cylinder extending axially therefrom, and the latch fixing sleeve is installed on the latch limiting column; a ratchet is provided at the end of the clutch center shaft, and the ratchet is connected to the inner wall of the clutch drive driven wheel by an elastic member.

[0012] When the clutch drive pin on the clutch drive driven wheel is within the flat slope section, the ratchet is connected to the clutch drive driven wheel via the elastic member, preventing the clutch connecting sleeve from moving axially. At this point, the external spline and the first internal spline engage with each other, preventing the clutch connecting sleeve from rotating. Because the ratchet is connected to the clutch drive driven wheel, the clutch center shaft rotates, the latch teeth disengage the annular limit groove, and the clutch lock spring is compressed. The clutch drive driven wheel continues to rotate, and the clutch drive pin slides within the slope section, driving the clutch connecting sleeve toward the ring gear connecting plate. The clutch lock module then moves as a whole toward the ring gear connecting plate, causing the ratchet to disengage from the elastic member. Under the action of the clutch spring lock force, the two clutch latches automatically reset. When the clutch drive pin reaches the end of the slope section, the external spline on the clutch connecting sleeve disengages from the second internal spline on the ring gear connecting plate, disengaging the clutch assembly.

[0013] Preferably, the clutch central shaft is provided with a ratchet, a limit plate, a first slot and a driving end in sequence along its axial direction; the clutch cam is provided with a first cam, a second cam and an intermediate cam arranged in pairs, the first cam and the second cam being arranged on both sides of the intermediate cam; the two intermediate cams are symmetrically arranged and both are arranged on the same axis, the first cam and the second cam are set at a distance and are respectively set at the same angle as the intermediate cam; a first latch limit groove is provided between the first cam and the intermediate cam, and a second latch limit groove is provided between the second cam and the intermediate cam; a polygonal through hole for inserting the driving end is provided on the central axis of the clutch cam; two central bearings arranged side by side are provided on the clutch central shaft, and the first slot is provided with a bearing retaining ring for limiting the axial movement of the central bearing; the clutch central shaft is installed in the clutch connecting sleeve through the central bearing and is coaxially arranged therewith; the limit plate is disc-shaped and has a fan-shaped notch on the limit plate. When the clutch central shaft drives the limit plate to rotate, the fan-shaped notch on the limit plate rotates relative to the limit bar in the clutch connecting sleeve; the clutch cam sleeve is mounted on the driving end.

[0014] When the clutch center shaft rotates, it drives the clutch cam. Clutch latches are located in both the first and second latch-limiting grooves of the clutch cam, and clutch lock springs are mounted on the clutch latches. When the clutch cam rotates, the intermediate cam and the first cam drive one clutch latch to move radially along the clutch connecting sleeve. When the clutch cam rotates, the intermediate cam and the second cam drive the other clutch latch to move radially along the clutch connecting sleeve. This facilitates the clutch cam's control of the clutch latch's relative movement to the clutch connecting sleeve, allowing the clutch latch to disengage from the annular limit groove. The sector-shaped notch on the limit plate interacts with the limit bar, limiting the clutch center shaft's rotation around its axis to within a certain angular range.

[0015] As preferably, the clutch cam is provided with a pair of clutch latches, the clutch latch comprising latch teeth, latch limit blocks, latch plates and latch protrusions, the clutch latch being mounted on the latch fixing sleeve, and baffles being provided at both ends of the latch fixing sleeve; each of the latch teeth passes through the latch guide hole and is located on the outside of the second cylindrical cylinder, the end face of the latch tooth facing the ratchet wheel is in contact with the side face of the external spline, and the side of the latch tooth away from the external spline is an inclined surface; a clutch lock spring is sleeved on the outer side of the latch plate, and the clutch lock spring is a compression spring; one end of the clutch lock spring abuts against the baffle plate, and the other end abuts against the latch limit block; each When the latch limit block and the inner wall of the clutch connecting sleeve are in contact with each other, the top of the latch tooth is higher than the external spline setting; the clutch cam is installed in the latch fixing sleeve, and the latch plate passes through the baffle so that the latch protrusion is in the latch fixing sleeve; the latch plate close to the end cover is clamped in the first latch limit groove, and one of the intermediate cam and the first cam simultaneously cooperates with the latch protrusion close to the end cover; the latch plate away from the end cover is clamped in the second latch limit groove, and the other intermediate cam and the second cam simultaneously cooperate with the latch protrusion away from the end cover; when the clutch center shaft drives the clutch cam to rotate, each of the clutch latches synchronously moves closer to each other along the radial direction of the clutch connecting sleeve.

[0016] The first latch plate is retained within the first latch stop groove, and the first latch protrusion engages with the intermediate protrusion and the first cam. Rotation of the clutch cam drives the first clutch latch radially along the clutch sleeve. Similarly, the second latch plate is retained within the second latch stop groove, and the second latch protrusion engages with the intermediate protrusion and the second cam. Rotation of the clutch cam drives the second clutch latch radially along the clutch sleeve. Initially, the clutch spring is compressed, and the latch stop engages the inner wall of the clutch sleeve, causing the highest point of the latch teeth to be higher than the external spline arrangement. When the external spline engages the second internal spline, the latch teeth automatically engage within the annular stop groove. When the clutch center shaft drives the clutch cam to rotate, the clutch cam simultaneously drives the two clutch latches radially toward each other, causing the latch teeth to be lower than the external spline arrangement on the clutch sleeve, facilitating automatic disengagement of the clutch assembly.

[0017] Preferably, the clutch drive driven wheel is coaxially sleeved on the clutch connecting sleeve and arranged close to the first cylindrical tube, and the hollow cylinder of the clutch drive driven wheel is provided with clutch drive pins arranged in pairs; the clutch drive pins are arranged higher than the outer wall of the hollow cylinder of the clutch drive driven wheel, and are symmetrically distributed on the hollow cylinder of the clutch drive driven wheel; the clutch drive pins are clearance-matched with the spiral groove, and the clutch drive pins slide along the spiral groove when the clutch drive driven wheel rotates; one end of the elastic member is fixedly mounted on the inner wall of the clutch drive driven wheel, and the other end of the elastic member is stuck on the contact surface of the ratchet when the clutch connecting sleeve is close to the clutch drive driven wheel; the end face of the elastic member facing away from the ratchet is set to an inclined arc surface, and the elastic members are arranged in pairs and are symmetrical relative to the center of the clutch drive driven wheel.

[0018] When the clutch driven wheel rotates, it drives the clutch drive pin to slide within the spiral groove, thereby pushing the clutch coupling sleeve to move axially. An elastic member is fixedly mounted on the inner wall of the clutch driven wheel. When the clutch coupling sleeve and clutch driven wheel are positioned adjacent to each other, the clutch drive pin is stuck in the flat slope of the spiral groove, and the elastic member contacts the surface of the ratchet wheel. When the clutch drive pin is in the slope of the spiral groove, the elastic member disengages from the surface of the ratchet wheel.

[0019] Preferably, the reducer assembly includes a first-stage planetary reduction mechanism consisting of a first-stage sun gear, a first-stage ring gear, a first-stage planetary gear and a first-stage planetary carrier, and also includes a second-stage planetary reduction mechanism consisting of a second-stage sun gear, a second-stage ring gear, a second-stage planetary gear, a second-stage planetary carrier and a reduction output gear; the first-stage sun gear is located at the end of the transmission shaft away from the motor, the second-stage sun gear and the second-stage planetary carrier are sleeved on the transmission shaft and can rotate relative to the transmission shaft; the first-stage planetary carrier is transmission-connected to the second-stage sun gear, the second-stage planetary carrier is fixedly connected to the reducer output gear, the side of the drum body is provided with drum internal teeth, the reducer output gear is transmission-connected to the drum internal teeth, and the second-stage ring gear is fixedly connected to the outer casing.

[0020] When the motor is working, it drives the transmission shaft to rotate, and the transmission shaft is respectively connected to the first-stage planetary reduction mechanism and the second-stage planetary reduction mechanism, thereby facilitating the conversion of the motor's rotation ratio and making the rotation speed of the drum body more stable and reliable.

[0021] Preferably, the brake assembly includes a brake seat, a locking bolt, a main brake disc, a secondary brake disc, a main brake sleeve, a secondary brake sleeve, a brake shaft, a coupling and brake pads arranged in pairs; the output shaft of the motor is connected to the brake shaft by a coupling, the delivery shaft of the motor is splined to one end of the coupling, and the other end of the coupling is splined to one end of the brake shaft; the other end of the brake shaft is connected to the main brake sleeve, and the main brake sleeve is provided with an external thread; the inner wall of one end of the main brake disc close to the main brake sleeve is provided with an internal thread that engages with the external thread on the main brake sleeve, and the main brake sleeve is threadedly connected to the main brake disc; a brake seat and brake pads arranged in pairs are provided on the cylinder of the main brake disc, and the brake seat is provided between the two brake pads, and a locking bolt is provided to fix the two between the brake seat and the drum body; an internal thread is also provided on the inner wall of one end of the main brake disc close to the secondary brake disc, and the thread specifications of the internal threads at both ends of the main brake disc are the same and the thread directions are opposite; the outer wall of the secondary brake sleeve is provided with an internal thread that engages with the internal thread on the main brake disc The auxiliary brake sleeve is threadedly connected to the main brake disc, and the through hole in the center of the auxiliary brake sleeve is a regular inner hexagon; a first step is provided in the center of the auxiliary brake disc, one end of the auxiliary brake disc is sleeved on the outer layer of the main brake disc, and the other end is sleeved on the outer layer of the auxiliary brake sleeve.

[0022] When the winch needs to stop working and the motor stops rotating or the winch stops rotating due to an abnormal situation, the winch rope drives the drum to rotate in the opposite direction under stress. The power is transmitted in the opposite direction, the drive shaft reverses, and drives the auxiliary brake sleeve to rotate in the opposite direction, thereby tightening the thread, so that the main brake disc and the auxiliary brake disc approach the brake seat at the same time, clamping the brake pads and the brake seat to generate friction. The greater the traction load, the tighter the thread and the greater the friction, thus achieving anti-retraction braking. Using double brake pads to clamp the brake seat from both sides at the same time can respond to braking faster and further increase the braking friction to achieve better braking effect.

When the clutch assembly needs to be disengaged, the drive motor is rotated in the reverse direction, so that the outer spline automatically disengages from the second inner spline. The disengagement process is fast and reliable. Secondly, the brake assembly makes the braking state of the winch more stable and reliable, making the user safer when using the winch.

[0063] The specific operation process of this embodiment is as follows: when the winch clutch is in the engaged state, Figure 25As shown, the clutch connecting sleeve 92 is farthest from the clutch driven wheel 83, and the external spline 921 of the clutch connecting sleeve 92 is engaged with the second internal spline 521 on the ring gear connecting plate 52 and the first internal spline 111 on the end cover 11 at the same time. The ring gear connecting plate 52 is stuck by the external spline 921 on the clutch connecting sleeve 92 and cannot rotate. Since the first-stage ring gear 41 is fixedly connected to the ring gear connecting plate 52, the first-stage ring gear 41 cannot rotate either. The first-stage planetary reduction mechanism and the second-stage planetary reduction mechanism on the reducer assembly 4 can realize power transmission; the top of the latch tooth 951 is located in the annular limit groove 522, so that the clutch lock module 9 is stuck to form a stop effect to prevent the clutch from disengaging.

[0064] When the rope needs to be released manually, the clutch drive motor 81 is started, and the clutch drive active wheel 82 drives the clutch drive driven wheel 83 to rotate, and the clutch drive pin 86 begins to slide in the spiral groove 922; the clutch drive pin 86 first slides in the flat slope section 9222, at which time the clutch drive driven wheel 83 will not drive the clutch connecting sleeve 92 to move axially; because the outer spline 921 of the clutch connecting sleeve 92 is engaged with the second inner spline 521, the clutch connecting sleeve 92 will not rotate either; at this time, the elastic member 85 drives the ratchet 911 on the clutch center shaft 91 to rotate, and the clutch center shaft 91 rotates relative to the clutch connecting sleeve 92, then the clutch cam 93 will drive the two clutch latches 95 to approach each other along the radial direction of the clutch connecting sleeve 92, then the latch teeth 951 will disengage from the annular limit groove 522, and the clutch lock spring 97 will be further compressed. Figure 26 As shown, the clutch drive driven wheel 83 continues to rotate, and the clutch drive pin 86 will slide in the slope section 9221, thereby driving the clutch connecting sleeve 92 to move axially toward the clutch drive driven wheel 83. Then the clutch lock module 9 as a whole moves axially toward the clutch drive driven wheel 83, and the ratchet 911 disengages from the elastic member 85. After the ratchet 911 loses the limit of the elastic member 85, under the elastic force of the clutch lock spring 97, the two clutch latches 95 move away from each other and automatically reset; when the clutch latch 95 automatically resets, it will drive the clutch cam 93 and the clutch center shaft 91 to reverse synchronously; when the clutch drive pin 86 reaches the end of the ramp section 9221, the outer spline 921 of the clutch connecting sleeve 92 is disengaged from the second inner spline 521 of the ring gear connecting plate 52, and the two latch teeth 951 will contact each other with the bottom of the first inner spline 111; at this time, the ring gear connecting plate 52 and the first-stage ring gear 41 can rotate freely around the axis, and power transmission cannot be performed. The drum body 3 can be manually rotated to release the rope.

[0065] like Figure 27As shown, when it is necessary to rewind the rope or pull the load, the clutch drive motor 81 is started, the clutch drive motor 81 is reversed, and the clutch drive driven wheel 82 drives the clutch drive driven wheel 83 to rotate in the opposite direction. The clutch drive pin 86 first slides on the slope section 9221, driving the clutch connecting sleeve 92 to move axially, and the clutch lock module 9 as a whole moves axially toward the ring gear connecting plate 52. Because the surfaces opposite to the second internal spline 521 of the latch tooth 951 are both inclined surfaces, no matter what angle the ring gear connecting plate 52 rotates to, the guiding effect of the inclined surface will automatically align the external spline 921 with the second internal spline to complete the engagement, and there is no need to manually rotate the drum body 3 to adjust the angle; during the axial movement of the clutch lock module 9, the clutch drive driven wheel 83 drives the elastic member 85 to rotate in the opposite direction relative to the ratchet 911, so the clutch center shaft 91 will not rotate relative to the clutch connecting sleeve 92. 1. The elastic member 85 and the ratchet 911 are more likely to return to the transmission contact state; when the clutch driving pin 86 reaches the flat slope section 9222, the clutch lock module 9 ends axial movement, and the top of the latch tooth 951 is automatically inserted into the annular limit groove 522 to lock the clutch lock module 9. The clutch drives the driven wheel 83 to continue rotating until the clutch driving pin 86 reaches the end of the flat slope section 9222, at which time it returns to the engaged state of the clutch assembly 5; start the motor 2, and drive the main brake sleeve 65 to rotate through the coupling 68 and the brake shaft 67. The main brake sleeve 65 drives the main brake disc 63 away from the brake seat 61 through the thread and then starts to rotate. Since the threads connecting the other end of the main brake disc 63 to the auxiliary brake sleeve 66 are in opposite directions, the main brake disc 63 drives the auxiliary brake sleeve 66 away from the brake seat 61 when it rotates. The main brake disc 63 and the auxiliary brake disc 64 release the brake pad 62, and the auxiliary brake sleeve 66 drives the transmission shaft 7 to rotate, and drives the drum body 3 to rotate through the reducer assembly 4.

[0066] When the winch needs to stop working and the motor 2 stops rotating or the winch stops rotating due to an abnormal situation, the rope drives the drum body 3 to rotate in the opposite direction under the stress state, and the power is transmitted in the opposite direction, the transmission shaft 7 reverses, and drives the auxiliary brake sleeve 66 to rotate in the opposite direction, thereby tightening the thread, so that the main brake disc 63 and the auxiliary brake disc 64 approach the brake seat 61 at the same time, clamping the brake pad 62 and the brake seat 61, generating friction. The greater the traction load and the tighter the thread, the greater the friction, thereby achieving anti-retraction braking. Using double brake pads 62 to clamp the brake seat 61 from both sides at the same time can respond to braking faster and further increase the braking friction to achieve better braking effect.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
