[0024] like Figure 1-Figure 3 As shown, the utility model provides a ratchet brake device, which is used on a winch; it includes a support frame 1, a pawl drive assembly 6, a pawl transmission assembly, and a pawl 5, the pawl drive assembly 6 is fixed on the support frame 1, the pawl 5 is swingably installed on the support frame 1, and the pawl 5 is connected to the pawl drive assembly 6 through the pawl transmission assembly; a ratchet 12 is also provided on the drum 11 of the winch, and the pawl 5 engages with the ratchet 12 under the action of the pawl drive assembly 6 to block the rotation of the drum 11.

[0025] The ratchet brake device of the utility model is provided with a ratchet 12 on the drum 11, and the ratchet driving assembly 6 drives the ratchet 5 to engage with the ratchet 12 to limit the rotation of the drum 11. When the winch has an equipment failure causing the drum 11 to rotate rapidly, it can be quickly limited to avoid mechanical damage and safety problems.

[0026] Preferably, Figure 1As shown, the support frame 1 includes four columns, a drive frame 2, an adjusting rod 3, and a spring 4. The four columns are divided into a front support frame 101 and a rear support frame 102 in groups of two. The bottom ends of the front support frame 101 and the rear support frame 102 are fixed on the winch; the drive frame 2 includes two drive frame outer frames, a first drive frame connecting rod, and a second drive frame connecting rod. The two drive frame outer frames are connected by the first drive frame connecting rod and the second drive frame connecting rod. The drive frame outer frame is hinged at the top end of the front support frame 101, the first drive frame connecting rod is hinged to the pawl drive assembly 6, and the second drive frame connecting rod is hinged to the left end of the adjusting rod 3; the pawl 5 is swingably installed in the rear support frame 102, and the left end of the pawl 5 is connected to the right end of the adjusting rod 3; a fixing plate 1021 is also provided on the top of the rear support frame 102, the top of the spring 4 is connected to the bottom surface of the fixing plate 1021, and the bottom end of the spring 4 is connected to the top surface of the left end of the pawl 5.

[0027] Further, in the present embodiment, the shape of the drive frame outer frame is roughly L-shaped, and there are three through holes on the drive frame outer frame, namely, a first through hole, a second through hole, and a third through hole, wherein the first through hole is arranged at the left end of the drive frame outer frame, the second through hole is arranged at the upper right end of the drive frame outer frame, and the third through hole is arranged at the lower right end of the drive frame outer frame. The first drive frame connecting rod is penetrated in the first through hole, the second drive frame connecting rod is penetrated in the second through hole, a drive frame outer frame through hole is opened on the drive frame outer frame, the third through hole is aligned with the drive frame outer frame through hole, and a pin is penetrated between the two. The two drive frame outer frames are arranged parallel to each other in the front-to-back direction. A ratchet through hole is opened on the ratchet 5 in the front and back, and a fourth through hole is opened on the rear support frame 102, the ratchet through hole is aligned with the fourth through hole, and a pin is penetrated between the two, so that the ratchet 5 can swing in the rear support frame 102.

[0028] Further, in this embodiment, the connection point between the first drive frame connecting rod and the pawl driving assembly 6 is the first hinge point, the connection point between the second drive frame connecting rod and the adjustment rod 3 is the second hinge point, the connection point between the drive frame outer frame and the front support frame 101 is the third hinge point, and the connection point between the pawl 5 and the rear support frame 102 is the fourth hinge point. The first drive frame connecting rod and the second drive frame connecting rod can both adopt pins.

[0029] In this embodiment, the driving frame 2 is a curved arm, and the adjusting rod 3 is a straight arm.

[0030] Preferably, in this embodiment, the pawl drive assembly 6 adopts an electric hydraulic pusher; the push rod in the electric hydraulic pusher is hinged with the first drive frame connecting rod. The electric hydraulic pusher includes a hydraulic cylinder, an impeller, an impeller drive motor, a piston, and a push rod. The impeller drive motor is arranged below the hydraulic cylinder. The hydraulic cylinder is divided into a lower impeller compartment and an upper working compartment. The impeller is arranged in the impeller compartment and the impeller is connected to the rotor of the impeller drive motor. The bottom end of the push rod is fixedly connected to the piston, and the piston is arranged in the working compartment. A cylinder sleeve is also arranged outside the piston, and the cylinder sleeve is combined with the hydraulic cylinder body as a whole. When the impeller drive motor drives the impeller to rotate, the rotation of the impeller will generate pressure in the hydraulic cylinder. Under the influence of the pressure, the hydraulic oil is sucked from the upper part of the piston to the lower part of the piston, thereby forcing the piston to move upward, and the movement of the piston drives the push rod to move upward. When the impeller drive motor stops, the impeller stops rotating, and the piston rapidly drops under the action of the reset assembly and its own gravity. The hydraulic oil flows back from the lower part of the piston to the upper part of the piston, and the electric hydraulic pusher is reset.

[0031] Further, such as Figure 2 , Figure 3 As shown, in this embodiment, the clockwise rotation of the drum 11 is set as the lifting process, and the counterclockwise rotation is set as the descending process. When the drum 11 rotates clockwise and counterclockwise, the operator starts the electric hydraulic pusher, the left end of the drive frame 2 moves upward, the lower right end of the drive frame 2 rotates clockwise around the third hinge point, and the upper right end of the drive frame 2 moves downward, thereby driving the adjustment rod 3 to move downward, the pawl 5 swings counterclockwise around the fourth hinge point, and the right end of the pawl 5 moves away from the ratchet 12, so as not to block the rotation of the drum 11; at this time, the spring 4 is in a stretched state. When the winch fails or needs to stop after being lifted to the expected position, the operator turns off the electric hydraulic pusher, and the spring 4 recovers from the stretched state to the normal state. The spring 4 provides an upward pulling force to the left end of the pawl 5, and the pawl 5 will swing clockwise around the fourth hinge point. The right end of the pawl 5 will be close to the ratchet 12 to block the rotation of the drum 11. At the same time, the push rod of the electric hydraulic pusher moves downward under the action of gravity, and the left end of the drive frame 2 moves downward. The lower right end of the drive frame 2 will rotate counterclockwise around the third hinge point, and the upper right end of the drive frame 2 will move upward, thereby driving the adjusting rod 3 to move upward, completing the reset of the pawl drive assembly 6 and the pawl transmission assembly.

[0032] Preferably, Figure 1 As shown, a plurality of reinforcing rods 103 are provided between the front support frame 101 and the rear support frame 102; a plurality of reinforcing rods 103 are provided between the two upright posts of the front support frame 101 and between the two upright posts of the rear support frame 102. In this embodiment, the purpose of the reinforcing rods 103 is to ensure the strength of the support frame 1.

[0033] To achieve the above purposes or other purposes, such as Figure 2 , Figure 3 As shown, the utility model also discloses a winch, having the above-mentioned ratchet brake device, including a base plate bracket 7, a drive motor 8, a clamping brake 9, a gearbox 10, a transmission shaft 14, a drum 11, a drum support frame 13, and a controller (the controller is not drawn), the drive motor 8, the gearbox 10, and the drum support frame 13 are all welded and fixed on the base plate bracket 7; the motor shaft of the drive motor 8 is connected to the input end of the gearbox 10, the transmission shaft 14 is connected to the output end of the gearbox 10, and the front end end of the transmission shaft 14 is installed on the drum support frame 13 through a bearing; the drum 11 is sleeved on the outer circumferential surface of the transmission shaft 14, and the drum 11 and the transmission shaft 14 move synchronously; the clamping brake 9 is arranged on the outer circumferential surface of the motor shaft; the controller is electrically connected to the drive motor 8, the clamping brake 9, and the ratchet drive assembly 6.

[0034] Preferably, in the present embodiment, the clamp type brake 9 includes a clamp support frame, a clamp drive assembly, a clamp transmission assembly, and a clamp, the clamp drive assembly is arranged on the clamp support frame, the clamp can be tensioned and arranged in the clamp support frame, and the clamp is connected to the clamp drive assembly through the clamp transmission assembly. In the present embodiment, the clamp type brake 9 is a prior art, such as an electric hydraulic brake with a bulletin number of CN217081183U, which will not be repeated here. When the winch is working normally, the clamp type brake 9 is in a powered working state, and the clamp will not clamp the motor shaft. When the clamp type brake 9 is in a powered-off state, the reset member in the clamp type brake 9 will drive the clamp to clamp the motor shaft.

[0035] Preferably, in this embodiment, the drum 11 includes a rope winding area and two baffles, which are arranged at both ends of the rope winding area, and the sling rope is wound in the rope winding area. The ratchet 12 is arranged on the transmission shaft 14, or the ratchet 12 is arranged on the baffles at both ends of the drum 11. In this embodiment, the ratchet 12 is arranged on the baffle at the front end of the rope winding area. The ratchet brake device is arranged between the drive motor 8 and the drum 11.

[0036] Preferably, in this embodiment, the parameters of the clamp driving assembly are the same as those of the pawl driving assembly 6. The purpose of setting the parameters of the clamp driving assembly and the pawl driving assembly 6 to be the same is that when the controller issues a control command, the clamp driving assembly and the pawl driving assembly 6 can act at the same time, the clamp driving assembly drives the clamp to clamp the motor shaft of the drive motor 8, and the pawl driving assembly 6 drives the pawl 5 to limit the rotation of the reel 11, providing double protection and effectively avoiding safety hazards.

[0037] Preferably, in the present embodiment, the controller adopts a cam type controller, which is a prior art, for example, a cam controller for a single-pole crane with announcement number CN206947193U, which will not be repeated here.

[0038] The ratchet brake device involved in the utility model has the following working principles and steps:

[0039] S1: According to the attached Figure 1-Figure 3 , and the description of the above components, install each component;

[0040] S2: When the reel 11 needs to lift a heavy object, the operator starts the drive motor 8 through the controller. The motor shaft of the drive motor 8 drives the transmission shaft 14 to rotate through the gearbox 10. The rotation of the transmission shaft 14 drives the reel 11 to rotate. The reel 11 rotates clockwise to lift the heavy object. At this time, the controller starts the clamp drive assembly and the ratchet drive assembly 6. The clamp drive assembly drives the clamp away from the motor shaft through the clamp transmission assembly; the push rod of the ratchet drive assembly 6 moves upward, driving the left end of the drive frame 2 to move upward, the lower right end of the drive frame 2 will rotate clockwise around the third hinge point, and the upper right end of the drive frame 2 will move downward, thereby driving the adjustment rod 3 to move downward, the ratchet 5 will rotate counterclockwise around the fourth hinge point, and the right end of the ratchet 5 will be away from the ratchet wheel 12, which will not block the rotation of the reel 11. At this time, the spring 4 is in a stretched state.

[0041] S3: When the reel 11 needs to lower the heavy object, the operator starts the drive motor 8 in reverse through the controller, and the motor shaft of the drive motor 8 drives the transmission shaft 14 to rotate through the gearbox 10. The rotation of the transmission shaft 14 drives the reel 11 to rotate, and the reel 11 rotates counterclockwise to lift the heavy object. At this time, the hoop drive assembly and the pawl drive assembly 6 are both in a working state, and the working state is the same as the working process in S2, which will not be repeated here.

[0042] S4: When the weight in steps S1 and S2 moves to the expected position, the operator adjusts the controller to the static position, at which time the drive motor 8, the clamp drive assembly, and the ratchet drive assembly 6 are all powered off. After the clamp drive assembly is powered off, the reset member in the clamp brake 9 will drive the clamp to clamp the motor shaft. When the ratchet drive assembly 6 is powered off, the spring 4 recovers from the stretched state to the normal state, and the spring 4 provides an upward pulling force to the left end of the ratchet 5. The ratchet 5 will rotate clockwise around the fourth hinge point, and the right end of the ratchet 5 will be close to the ratchet 12 to block the rotation of the reel 11. At the same time, the push rod of the ratchet drive assembly 6 moves downward under the action of gravity, the left end of the drive frame 2 moves downward, the lower right end of the drive frame 2 will rotate counterclockwise around the third hinge point, and the upper right end of the drive frame 2 will move upward, thereby driving the adjustment rod 3 to move upward, completing the reset of the ratchet drive assembly 6 and the ratchet transmission assembly.

[0043] S5: When the winch fails during operation (gear breakage of the gearbox 10, breakage of the transmission shaft 14, etc.), the operator observes the working state of the winch and uses the controller to cut off the power of the drive motor 8, the clamp drive assembly, and the ratchet drive assembly 6. At this time, the clamp brake 9 and the ratchet brake device both block the winch, and the working process is the same as in step S4, which will not be repeated here.

[0044] S6: When the winch is suddenly powered off during operation, the clamp brake 9 and the ratchet brake device both block the winch. The working process is the same as the process of the operator actively cutting off the power in step S4, and will not be repeated here.

[0045] The ratchet brake device and winch involved in the utility model have the following beneficial effects:

[0046] 1. A spring 4 is provided in the ratchet brake device of the utility model. When the ratchet drive assembly 6 works normally, the left end of the ratchet 5 always has an upward pulling force. When the ratchet drive assembly 6 fails and cannot apply a force to the ratchet 5 through the drive frame 2 and the adjustment rod 3, the ratchet 5 will be stuck on the ratchet 12 clockwise, making the ratchet brake device a normally closed brake to avoid the existence of hidden dangers.

[0047] 2. In the present invention, the pawl driving assembly 6 drives the driving frame 2 and the adjusting rod 3 to apply force to the pawl 5, so that the pawl 5 and the ratchet wheel 12 can be quickly separated, so that the drum 11 of the winch is quickly released from the brake and becomes a free rotation state.

[0048] 3. In the utility model, the push rod, the drive frame 2 and the adjusting rod 3 of the ratchet driving assembly 6 are all connected by pins, so they can rotate flexibly and transmit force clearly.

[0049] 4. The ratchet drive assembly 6 and the clamp drive assembly in the utility model have the same model and performance parameters, which can ensure the synchronization of the two braking functions.

[0050] 5. The utility model solves the problem of the hoist rope falling down due to the abnormality between the motor shaft and the gearbox 10, between the gears in the gearbox 10, and between the gearbox 10 and the transmission shaft 14, so that the drum 11 body has braking performance, establishes a double braking function, increases the braking reliability of the hoist, and adds a barrier to construction safety. It is easy to install, easy to operate and maintain, low cost, safe and reliable.

[0051] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
