Problems solved by technology
At present, because the winch needs a large torque when lifting the hook to lift the tamper, the general operator will increase the accelerator to increase the engine speed to increase the drive winch torque. After the engine speed increases, then manipulate the winch handle to make the winch clutch Engagement, this operation mode will make the speed difference between the drive gear of the winch and the reel larger, and the internal dynamic friction of the winch clutch will increase, resulting in premature damage to the winch clutch and a decrease in safety

Embodiment Construction
[0018] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0019] Such as figure 1 As shown, the present invention provides a hoist clutch slipping alarm system according to the first embodiment, which includes a hoist 10, a controller, an engine speed transmission, and a hoist handle 18, and a hoist clutch 104 is installed on the hoist 10 , the winch handle 18 is used to control the engagement and separation of the winch clutch 104, the controller collects the actual engine speed through the engine speed transmitter in real time, the engine speed threshold is preset in the controller, when the actual engine speed is lower than the When the engine speed threshold is reached, the winch handle 18 can manipulate the winch clutch 104 to engage to prevent th...

The invention discloses a winch clutch slipping alarm system and a dynamic compaction machine. The system comprises a controller, a first rotating speed sensor, a second rotating speed sensor and an alarm device. The first rotating speed sensor detects the rotating speed of a driving gear, the second rotating speed sensor detects the rotating speed of a winding cylinder, when a winch clutch is inthe engaging state, the controller obtains signals of the first rotating speed sensor and the second rotating speed sensor, the rotating speed difference of the driving gear and the winding cylinder is judged, and when the rotating speed difference reaches the preset value, the controller sends out an alarm signal to the alarm device. The winch clutch is protected, the service life of the winch clutch is prolonged, and the use safety of the winch clutch is improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a winch clutch slipping alarm system and a dynamic compaction machine. Background technique [0002] The dynamic tamping machine is a machine that needs to compact loose soil in construction projects. The working principle is to repeatedly lift the rammer to a certain height, then lower the rammer, and the free-falling rammer compacts the loose soil. The winch drive generally adopts mechanical drive or hydraulic drive. At present, because the winch needs a large torque when lifting the hook to lift the tamper, the general operator will increase the throttle to increase the engine speed to increase the driving torque of the winch. After the engine speed increases, then manipulate the winch handle to make the winch clutch Engaging, this operation mode will make the speed difference between the driving gear of the winch and the reel larger, and the internal dynamic friction of ...
