The brake system is used to control the operation of the gearbox 3. The hydraulic system includes: a hydraulic gear pump 6, which is arranged in the gearbox 3 and driven by the gearbox 3; a hydraulic motor 7, which is arranged on the take-up device and drives the winding of the auxiliary steel wire rope; a throttle valve 8, which connects the output end of the hydraulic gear pump 6 and the input end of the hydraulic motor 7; a tension sensor 9, which detects the tension of the auxiliary steel wire rope in real time; and a controller 10, which receives the signal from the tension sensor 9 and dynamically adjusts the opening of the throttle valve 8 by calculating the tension deviation to keep the tension of the auxiliary steel wire rope at the set value. Furthermore, the tension deviation calculation method of the controller 10 includes the following steps: S1. Obtain the auxiliary wire rope tension value F in real time through the tension sensor 9; S2. The controller 10 calculates the tension deviation ; S3. If |ΔF|> threshold, then output control signal to throttle valve 8 according to PID algorithm; S4. Throttle valve 8 adjusts the flow of hydraulic motor 7 so that ΔF approaches 0; When the auxiliary rope tension increases → tension sensor 9 detects F> → Controller 10 increases the opening of throttle valve 8 → Hydraulic motor 7 accelerates → Reel 17 reels faster → Auxiliary rope tension is restored to If the tail rope is loose (F< ), the hydraulic motor 7 slows down to avoid the auxiliary wire rope from accumulating and jumping out of the groove, thus improving the safety during the reeling; Furthermore, a threaded gear 11, a ratchet gear 12, a pawl plate 13, and a ratchet plate 15 are provided on the frame 1.

The ratchet disc 15 drives the pawl disc 13 to achieve unidirectional rotation, preventing the hydraulic gear pump 6 from sucking back. After the hydraulic gear pump 6 is running, it drives the hydraulic motor 7 through the throttle valve 8 to start working. During this process, the tension sensor 9 detects the tension of the auxiliary steel wire rope in real time.

The driving wheel 20 and the driven wheel 19 are engaged with each other. After the output shaft of the gearbox 3 rotates, the driving wheel 20 drives the driven wheel 19 to rotate together, thereby driving the rotating shaft 18 to rotate, and then driving the reel 2 to rotate, so as to achieve the winding of the main wire rope and the auxiliary wire rope; Furthermore, the clutch 4 includes a main shaft 21, a clutch plate 22, an opening and closing nut 23, a fixing seat 24, a connecting piece 1 25, a connecting piece 2 26, a connecting piece 3 27, and an anti-slip ring 28. The anti-slip ring 28, the connecting piece 1 25, the connecting piece 2 26, the connecting piece 3 27, and the fixing seat 24 are all sleeved on the main shaft 21 and have mounting holes 14 on their surfaces and are connected in sequence by bolts. One side of the connecting piece 26 is fixedly connected to a connecting shaft 29 connected to the output end of the engine 5. The clutch plate 22 is slidably connected to the main shaft 2 1, a slot 30 is provided on the fixing seat 24 for the clutch disc 22 to be inserted into, the main shaft 21 is rotatably connected to the connecting seat 31 and one end is connected to the input end of the gearbox 3, the opening and closing nut 23 is threadedly connected to the outer wall of the connecting seat 31 and is rotatably connected to the clutch disc 22 on the side away from the connecting seat 31, and the gearbox 3 is provided with a handle 32, the handle 32 is fixedly connected to the sector gear 33, and the outer wall of the opening and closing nut 23 is fixedly connected to a gear 34 that meshes with the sector gear 33. After the engine 5 is started, its output The end drives the connecting shaft 29 to rotate, and the connecting shaft 29 drives the connecting piece 2 26 to rotate. Since the anti-slip ring 28, the connecting piece 1 25, the connecting piece 2 26, the connecting piece 3 27, and the fixing seat 24 are all sleeved on the main shaft 21 and the surfaces are provided with mounting holes 14 and are connected in sequence by bolts, as the connecting piece 2 26 rotates, the anti-slip ring 28, the connecting piece 1 25, the connecting piece 3 27, and the fixing seat 24 all rotate together, and then the handle 32 is turned to drive the sector gear 33 to rotate, thereby driving the gear 1 engaged therewith. 34 rotates, and after the gear 1 34 rotates, the engaging nut 23 also rotates accordingly. Since the engaging nut 23 is threadedly connected to the outer wall of the connecting seat 31, the engaging nut 23 moves along the outer wall of the connecting seat 31, thereby driving the clutch plate 22 to move. When the clutch plate 22 moves to engage with the engaging groove 30 on the fixing seat 24, the main shaft 21 starts to rotate, thereby driving the transmission 3 to start. The clutch plate 22 can be separated from the fixing seat 24 by bending the handle 32 in the opposite direction, thereby disconnecting the power of the engine 5. Furthermore, a plurality of placement grooves 35 are provided on the connecting piece 3 27 , and a spring 36 is fixedly connected in the placement groove 35 . When the clutch disc 22 is inserted into the slot 30 , the engine 5 is started to drive the connecting shaft 29 to rotate and drive the connecting piece 3 27 to rotate. At this time, the spring 36 is affected and deformed to a certain extent, thereby generating elastic force, thereby playing a certain buffering role, avoiding direct action on the clutch disc 22 , achieving the purpose of soft starting, and reducing the wear of the clutch disc 22 . At the same time, the mounting hole 14 on the connecting piece 1 25 is a waist-shaped hole for adjusting the compressible stroke of the spring 36 . In order to reduce the friction loss generated when the opening and closing nut 23 and the clutch disc 22 rotate with each other, the opening and closing nut 23 and the clutch disc 22 are connected to each other in rotation via a bearing 1 . Furthermore, the brake system includes a gear shaft 37 driven by the gearbox 3, both ends of the gear shaft 37 are rotatably connected to the gearbox 3 through bearing 2, the threaded gear 11 is sleeved on the gear shaft 37 and threadedly connected to the gear shaft 37, a constellation 38 is fixedly connected to the gear shaft 37, a brake seat 39 is rotatably connected on the outer wall of the constellation 38, a plurality of needle rollers 40 are rotatably connected between the brake seat 39 and the constellation 38, one side of the brake seat 39 is rotatably connected to two brake pads 41, a star wheel 42 is provided between the two brake pads 41, a plurality of rotating grooves 43 are provided on the side wall of the star wheel 42, and brake rollers 44 are provided in the rotating grooves 43. When the two brake pads 41 abut against the two sides of the star wheel 42, the brake pads 41 restrict the brake rollers 44 in the rotating grooves 43, and the engine 5 is started to rotate forward to drive the clutch 4 to drive the gearbox 3 to work. Under the action of the thread, the threaded gear 11 moves tightly to press the brake. The wheel plate 41 is transmitted to the constellation 38 by the threaded gear 11 through the transmission torque, and then guided to the gear shaft 37 by the constellation 38 for power output. When the engine 5 is running in reverse, the threaded gear 11 moves to the other side under the action of the thread to loosen the brake plate 41. At this time, the brake roller 44 is in a free state and automatically falls into the running state. The power torque is transmitted to the gear shaft 37 by the threaded gear 11. When braking, the clutch 4 is disconnected from the gearbox 3. The lifted weight provides a reverse torque. The gear shaft 37 is passively reversed. Under the action of the thread, the threaded gear 11 moves to drive the brake plate 41 to be pressed tightly. The brake roller 44 is thrown outward at a high speed under the action of centrifugal force. The brake roller 44 is in a braking state. The reverse weight torque is transmitted to the brake seat 39 by the brake roller 44. The brake seat 39 is fixed to the housing of the gearbox 3. Finally, the braking is completed, ensuring the reliability of the brake and improving the response time of the brake. Furthermore, a holder 45 is fixedly connected to the housing of the gearbox 3. The holder 45 is provided with a plurality of positioning grooves 46 for the shift handle on the gearbox 3 to be inserted into. The shift handle is also provided with a torsion spring 47. The elastic force of the torsion spring 47 improves the stability of the shift handle when it is inserted into the positioning groove 46, thereby preventing the shift handle from being shifted. Furthermore, the gearbox 3 is driven by a planetary gear assembly, and the gear shaft 37 is engaged in the planetary gear assembly. The planetary gear assembly has the advantages of small size, strong load-bearing capacity, high efficiency, and can realize multi-gear switching.

[0021] The working principle of the present invention is as follows: The main steel wire rope and the auxiliary steel wire rope are wound on the drum 2 in sequence, and then one end of the auxiliary steel wire rope is wound on the reel 17. Then, the engine 5 is started to rotate the output end of the engine 5, and the output end of the engine 5 drives the connecting shaft 29 to rotate. At this time, the connecting piece 26 connected to the connecting shaft 29 drives the anti-slip ring 28, the connecting piece 1 25, the connecting piece 3 27, and the fixing seat 24 to rotate together. When the connecting piece 3 27 rotates, the spring 36 in the placement groove 35 is affected and deformed to a certain extent, thereby generating elastic force, thereby playing a certain buffering role, avoiding direct action on the clutch disc 22, achieving the purpose of soft starting, and reducing the wear of the clutch disc 22; Then, the handle 32 is used to control the opening and closing nut 23 to move along the outer wall of the connecting seat 31, thereby driving the clutch plate 22 to move. When the clutch plate 22 moves to engage with the clamping groove 30 on the fixing seat 24, the main shaft 21 starts to rotate, thereby driving the output shaft of the gearbox 3 to rotate. After the output shaft of the gearbox 3 rotates, the driving wheel 20 drives the driven wheel 19 to rotate together, thereby driving the rotating shaft 18 to rotate, and then driving the drum 2 to rotate, thereby achieving the winding of the main wire rope and the auxiliary wire rope. When it is necessary to release the rope, the handle 32 can be used to disconnect the clutch 4 from the engine 5. After losing power, the drum 2 will reverse under the influence of the heavy object being lifted, thereby achieving the effect of releasing the rope; During the reel 2 is being wound, the gear position can be adjusted using the shift handle on the gearbox 3 to change the output power of the gearbox 3 and thereby adjust the reeling speed of the reel 2. Furthermore, the elastic force of the torsion spring 47 improves the stability of the shift handle when it is engaged in the positioning groove 46, thereby preventing the shift handle from being misaligned and thus improving safety during operation. After the gearbox 3 is started, the threaded gear 11 will start to rotate, and the ratchet gear 12 engaged with it will start to rotate, thereby driving the ratchet disc 15 to rotate. At the same time, after the ratchet disc 15 rotates, the pawl disc 13 also starts to rotate and drives the hydraulic gear pump 6 to start running. After the hydraulic gear pump 6 is running, it drives the hydraulic motor 7 to start working through the conduit and the throttle valve 8, thereby driving the wire drum 17 to rotate, thereby starting the wire winding work. During this period, the tension sensor 9 will capture the tension of the auxiliary wire rope in real time. At the same time, the controller 10 calculates the tension deviation according to the tension deviation calculation method, thereby adjusting the opening of the throttle valve 8, thereby adjusting the output power of the hydraulic motor 7, and controlling the rotation speed of the wire drum 17 to keep the tension of the auxiliary wire rope at the set value, thereby improving the safety during wire winding.
