Description

Technical field:

[0002] The present invention relates to the technical field of capstan grinders, and in particular to a capstan grinder servo motor drive transmission mechanism and a working method thereof. Background technology:

[0004] At present, during the construction of power transmission projects in my country, most of the heavy objects and tools used for lifting are capstans. Capstans are essential construction equipment for tower assembly process and can provide necessary power for tower assembly construction smoothly and conveniently in various complex plateau and mountainous terrains. Existing capstans are generally driven by oil extraction machines, which cause serious pollution. The gearboxes are mostly manually operated for speed shifting, which has low maneuverability. Double-drum capstans generally have two transmission mechanisms, a gearbox and a bridge box. The overall size is relatively large, the integration is not high, and it is not convenient for transportation.

[0005] Therefore, it is necessary to develop a reasonable servo motor drive transmission mechanism for the capstan grinder to solve the above problems.

[0006] The defects of existing motorized capstans are:

[0007] Patent document CN105564444A discloses a double-drum capstan, including a base, on which an engine, a speed change device, an emergency external brake device and a transmission system are sequentially connected. A forward and reverse gear mechanism is provided on the base between the engine and the speed change device, and a torque limiter is provided on the base between the speed change device and the emergency external brake device. The power output ends of the transmission system are respectively connected to the first drum and the second drum. Although the capstan is reliable in operation, easy to operate, highly safe, has good braking performance and a wide range of applications, the forward and reverse gear mechanism is provided to facilitate reversing and ensure that the traction force for forward and reverse rotation is the same. When reversing, no matter forward rotation, idling or reverse rotation, only the reversing rod needs to be operated, and the operation is very simple. The torque limiter can effectively control overload operation to avoid overload accidents; however, the device is bulky, has a low degree of integration and is not easy to transport.

[0008] Patent document CN220642368U discloses a convenient double-drum capstan, including an operating table, the top of which is fixedly connected to a first motor, one side of the first motor is rotatably connected to a gearbox, and the side of the gearbox away from the first motor is fixedly connected to a capstan roller; through the structural design of the lifting assembly, although the capstan realizes different functions of the capstan in different working fields, the device is bulky, has low integration, and is not easy to transport.

[0039] First, the servo motor 111 on the first box wall 31 is connected to the motor connecting bolt group 112 to rotate, and the servo motor 111 drives the drive shaft 116 placed inside it to rotate, and then the two drive shafts 116 drive the two drive gears 114 to rotate through the flat key 115, and the drive gear 114 is transmitted to the first-stage driving gear 214, and then the first-stage transmission shaft 213 and the first-stage driven gear 215 are driven to rotate synchronously through the flat key, and then transmitted to the second-stage driving gear 225, and then the second-stage transmission shaft 223 and the second-stage driven gear 224 are driven to rotate synchronously through the flat key, and then transmitted to the third-stage driving gear 234, and then the third-stage driven gear 235 is driven by the flat key.

At this point, the servo motor transmits power to the output shaft. At the same time, the speed and direction of the output shaft transmitted by the multi-stage reduction transmission assembly can be controlled by controlling the speed and direction of the servo motor.

[0040] In one embodiment, the gears are all spur gears. It will be understood by those skilled in the art that the type of gears used in the device will vary with the needs of different deceleration requirements.
