Description

Technical Field

[0001] This utility model relates to the field of clutch device technology, specifically a new type of clutch device for a calcium carbide furnace discharge winch. Background Technology

[0002] The discharge winch of a calcium carbide furnace plays a crucial role in chemical production. Its clutch device directly affects the discharge efficiency and safety. Currently, the clutch device of the calcium carbide furnace winch uses an electro-hydraulic actuator. When the clutch is engaged, the electro-hydraulic actuator is energized, pushing the clutch drive wheel ratchet slider forward to engage with the driven wheel ratchet, driving the wire rope drum to rotate and pull back the wire rope. When the clutch is disengaged, the electro-hydraulic actuator is de-energized, and the clutch drive wheel ratchet slider is returned by the spring return force, and the clutch ratchet is disengaged.

[0003] The return spring in the existing clutch is easily damaged due to frequent clutch engagement and disengagement, requiring frequent repairs and replacements. The spring force decays rapidly, and when the spring force is insufficient, the clutch often fails to disengage automatically. This necessitates an employee to pry the clutch intermittently, increasing the workload of the furnace operator and posing risks of calcium carbide spillage and mechanical injury.

[0004] Therefore, a new type of clutch device for the discharge winch of a calcium carbide furnace is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of clutch device for a calcium carbide furnace discharge winch.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel clutch device for a calcium carbide furnace discharge winch includes: a base, a take-up roller rotatably mounted on the top of the base for winding a steel wire rope; a transmission assembly comprising a fixed ratchet gear rotatably mounted on the base, a first spur gear fixedly connected to the central shaft of the fixed ratchet gear, a second spur gear meshing with the first spur gear fixedly mounted on the central shaft of the take-up roller; a sleeve fixedly mounted on the base, a sliding ratchet gear meshing with the fixed ratchet gear slidably mounted on the sleeve; and a clutch assembly comprising a cylinder fixedly mounted on the top of the base, a remote control start device mounted on the cylinder, and an extended end of the cylinder movably connected to the side wall of the sliding ratchet gear.

[0008] Preferably, a through hole is provided at the center of the first spur gear and the fixed ratchet gear, and a bearing body is fixedly installed in the through hole.

[0009] Preferably, a third spur gear is rotatably mounted on the inner side of the bearing body, and the third spur gear is located inside the fixed ratchet.

[0010] Preferably, the sliding ratchet has an internal tooth groove at its center that meshes with the third spur gear.

[0011] Preferably, a motor is also fixedly installed on the base, and the output end of the motor is fixedly connected to the central shaft of the third spur gear.

[0012] Preferably, the sleeve has a movable hole at its center that matches the central shaft of the sliding ratchet, and a shift fork body is sleeved on the outer side of the central shaft of the sliding ratchet, with connecting rods sleeved on both sides of the shift fork body.

[0013] Preferably, the bottom ends of the two connecting rods are fixedly connected to a connecting shaft, and the connecting shaft is rotatably mounted on the base. A crank is fixedly connected to one side of the connecting shaft, and the top end of the crank is rotatably mounted on the output end of the cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a transmission component, when the fixed ratchet and the sliding ratchet mesh, the motor is energized. The motor drives the third spur gear inside the fixed ratchet to rotate within the bearing body. Since the third spur gear meshes with the internal tooth groove, it drives the sliding ratchet to rotate, and the sliding ratchet drives the fixed ratchet to rotate. At this time, the first spur gear rotates synchronously and drives the second spur gear to rotate, further enabling the take-up roller to rotate and wind up the wire rope, facilitating the winding of the output material. When the fixed ratchet and the sliding ratchet separate, the motor drives the third spur gear to idle within the bearing body in the through hole. At this time, the take-up roller does not rotate, facilitating the control of the take-up roller.

[0016] 2. By setting up a clutch assembly, when the operator remotely controls the cylinder to retract, the cylinder can pull the crank to rotate backward. At this time, the connecting shaft at the bottom of the crank can drive the shift fork body to slide away from the fixed ratchet through the connecting rod, which can quickly separate the sliding ratchet from the fixed ratchet. Compared with automatic separation by the return spring, it can avoid the problem of the fixed ratchet and sliding ratchet not being able to separate automatically due to damage to the return spring or the weakening of the elasticity, which can ensure the separation effect. Moreover, remote control can reduce the labor intensity of the operator and eliminate safety hazards. When the operator remotely starts the cylinder to extend, the sliding ratchet on the inner side of the shift fork body can mesh with the fixed ratchet, and the third spur gear can be embedded in the internal tooth groove, which can quickly achieve the transmission effect and ensure the winding effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] Please see Figures 1 to 3 A clutch device includes: a base 1, a take-up roller 10 rotatably mounted on the top of the base 1 for taking up a steel wire rope; the base 1 also includes a transmission assembly, which includes a fixed ratchet 4 rotatably fixedly mounted on the base 1; a first spur gear 5 fixedly connected to the central shaft of the fixed ratchet 4; a second spur gear 7 meshing with the first spur gear 5 fixedly mounted on the central shaft of the take-up roller 10; a sleeve 9 fixedly mounted on the base 1; a sliding ratchet 8 meshing with the fixed ratchet 4 slidably mounted on the sleeve 9; and a clutch assembly, which includes a cylinder 3 fixedly mounted on the top of the base 1; a remote control start device is also provided on the cylinder 3; and the extended end of the cylinder 3 is movably connected to the side wall of the sliding ratchet 8.

[0026] Please see Figure 3 The first spur gear 5 and the fixed ratchet gear 4 have a through hole 17 at their center, and a bearing body 16 is fixedly installed in the through hole 17.

[0027] Please see Figure 3 A third spur gear 15 is rotatably mounted on the inner side of the bearing body 16, and the third spur gear 15 is located inside the fixed ratchet 4.

[0028] Please see Figure 2 The sliding ratchet 8 has an internal tooth groove 12 at its center that meshes with the third spur gear 15.

[0029] Please see Figure 1 A motor 6 is also fixedly installed on the base 1, and the output end of the motor 6 is fixedly connected to the central shaft of the third spur gear 15.

[0030] In this embodiment, during use, when the fixed ratchet 4 and the sliding ratchet 8 are engaged, the motor 6 is energized. The motor 6 drives the third spur gear 15 inside the fixed ratchet 4 to rotate within the bearing body 16. Since the third spur gear 15 is engaged with the internal tooth groove 12, the third spur gear 15 drives the sliding ratchet 8 to rotate, and the sliding ratchet 8 drives the fixed ratchet 4 to rotate. At this time, the first spur gear 5 can rotate synchronously, and the first spur gear 5 can drive the second spur gear 7 to rotate, further enabling the take-up roller 10 to rotate, thus winding the wire rope and facilitating the hoisting of the output material. When the fixed ratchet 4 and the sliding ratchet 8 are separated, the motor 6 drives the third spur gear 15 to idle within the bearing body 16 in the through hole 17. At this time, the take-up roller 10 does not rotate, facilitating the control of the take-up roller 10.

[0031] Example 2:

[0032] Please see Figures 1 to 4 A new type of clutch device for a calcium carbide furnace discharge winch further includes: a movable hole 18 adapted to the central shaft of a sliding ratchet 8 is provided at the center of a sleeve 9, and a shift fork body 11 is also sleeved on the outer side of the central shaft of the sliding ratchet 8, with connecting rods 14 sleeved on both sides of the shift fork body 11.

[0033] Please see Figure 4 The bottom ends of the two connecting rods 14 are fixedly connected to the connecting shaft 13, and the connecting shaft 13 is rotatably mounted on the base 1. A crank 2 is fixedly connected to one side of the connecting shaft 13, and the top end of the crank 2 is rotatably mounted on the output end of the cylinder 3.

[0034] In this embodiment, during use, when the operator remotely controls the cylinder 3 to retract, the cylinder 3 can pull the crank 2 to flip backward. At this time, the connecting shaft 13 at the bottom of the crank 2 can drive the shift fork body 11 to slide away from the fixed ratchet 4 through the connecting rod 14, which can quickly separate the sliding ratchet 8 from the fixed ratchet 4. Compared with automatic separation by the return spring, it can avoid the problem that the fixed ratchet 4 and the sliding ratchet 8 cannot be automatically separated due to damage to the return spring or the loss of elasticity, thus ensuring the separation effect. Moreover, remote control can reduce the labor intensity of the operator and eliminate safety hazards. When the operator remotely starts the cylinder 3 to extend, the sliding ratchet 8 on the inner side of the shift fork body 11 can mesh with the fixed ratchet 4, and the third spur gear 15 can be embedded in the inner tooth groove 12, which can quickly achieve the transmission effect and ensure the winding effect.

[0035] Working principle: First, when the fixed ratchet 4 and the sliding ratchet 8 mesh, the motor 6 on the base 1 is energized. The motor 6 drives the third spur gear 15 inside the fixed ratchet 4 to rotate within the bearing body 16. Since the third spur gear 15 meshes with the internal tooth groove 12, it drives the sliding ratchet 8 to rotate, and the sliding ratchet 8 drives the fixed ratchet 4 to rotate. At this time, the first spur gear 5 rotates synchronously and drives the second spur gear 7 to rotate, further enabling the winding roller 10 to rotate and wind up the wire rope, facilitating the winding of the output material. When the operator remotely controls the cylinder 3 to retract, the cylinder 3 pulls the crank 2 to rotate backward. At this time, the connecting shaft 13 at the bottom of the crank 2, through the connecting rod 14, drives the fork body 11 away from the fixed ratchet 4. The sliding of one side of the fixed ratchet 4 allows the sliding ratchet 8 to quickly separate from the fixed ratchet 4. At this time, the motor 6 drives the third spur gear 15 to idle in the bearing body 16 within the through hole 17. The take-up roller 10 does not rotate, making it easier to control. Compared to automatic separation via a return spring, this avoids the problem of the fixed ratchet 4 and sliding ratchet 8 failing to separate automatically due to damage to the return spring or weakening of its elasticity, ensuring the separation effect. Furthermore, remote control reduces the labor intensity of workers and eliminates safety hazards. When the operator remotely starts the cylinder 3 to extend, the sliding ratchet 8 on the inner side of the shift fork body 11 can mesh with the fixed ratchet 4, and the third spur gear 15 can be embedded in the inner tooth groove 12, enabling rapid transmission and ensuring the winding effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
