Description

Technical Field

[0001] This utility model relates to the technical field of dynamic compaction machine devices, and in particular to a dynamic compaction machine winch mechanism driven by an electric motor. Background Technology

[0002] The power source for the hoisting mechanism of traditional dynamic compaction machines is mainly a diesel engine or a hydraulic motor.

[0003] While winch mechanisms that use hydraulic motors as the torque source can transmit torque to a certain extent, they also have certain shortcomings. The hydraulic system itself has a complex structure, containing a large number of hydraulic pipelines, hydraulic valves and other components. This not only increases the difficulty of equipment installation and maintenance, but also makes the hydraulic system prone to failures such as oil leaks, affecting the reliability and stability of the equipment.

[0004] Therefore, a hoisting mechanism for a dynamic compaction machine driven by an electric motor is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a hoisting mechanism for a dynamic compaction machine driven by an electric motor.

[0012] Preferably, a normally closed brake is installed on the drum.

[0013] Preferably, a caliper disc brake is installed on the drum.

[0014] Preferably, a hydraulic control system is also provided, wherein the normally open internal expansion clutch, caliper disc brake, and normally closed brake are all controlled by the hydraulic system.

[0015] Compared with the prior art, this utility model provides a hoisting mechanism for a dynamic compaction machine driven by an electric motor, which has the following advantages:

[0016] This invention utilizes a combination of a motor and a torque converter for drive, resulting in higher working efficiency.

[0017] Electric motors are easier to control precisely, which is conducive to the intelligent development of dynamic compaction machines;

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example:

[0026] Reference Figure 1-3 A hoisting mechanism for a dynamic compaction machine driven by an electric motor includes a drum 5, and further includes: an electric motor 1, with a torque converter 2 fixedly connected to the output end of the electric motor 1; a planetary reducer 4, fixedly connected to the output end of the torque converter 2, and the planetary reducer 4 is installed inside the drum 5; a normally open internal expansion clutch 7, installed on the output end of the planetary reducer 4; a universal joint 3, fixedly connected to the output end of the torque converter 2, with the other end of the universal joint 3 fixedly connected to the input end of the planetary reducer 4; a normally closed brake 6, and a caliper disc brake 8 are installed on the drum 5; and a hydraulic control system, wherein the normally open internal expansion clutch 7, the caliper disc brake 8, and the normally closed brake 6 are all controlled by a hydraulic system.

[0027] Torque converter 2 is also controlled hydraulically.

[0028] Before using this device, the power supply is turned on, the hydraulic system oil pump is started, the normally closed brake 6 is kept in a braking state by spring force because the hydraulic system does not supply oil, the drum 5 is locked and cannot rotate; the normally open internal expansion clutch 7 is in a disengaged state, and the output shaft of the planetary reducer 4 is not powered to the drum 5.

[0029] Then the ram is connected to the hook on the drum 5 via a wire rope. The wire rope is neatly wound in the spiral groove of the drum 5 to ensure that the force is evenly distributed during lifting.

[0030] The operator starts the motor 1 via the control panel. The motor 1 outputs power at the rated speed, driving the pump wheel of the hydraulic torque converter 2 to rotate. At this time, if the rammer is on the ground and the load is small, the turbine of the hydraulic torque converter outputs torque at a higher speed, which is transmitted to the planetary reducer 4 through the universal joint 3. The operator issues a lifting command via the control panel. The hydraulic oil enters the hydraulic cylinder of the normally open internal expansion clutch 7 through the pipeline, pushing the piston to close the clutch driving end and driven end. The power is transmitted to the drum 5, which begins to rotate forward. The wire rope gradually tightens, driving the rammer to rise at a uniform speed.

[0031] If an obstacle is encountered during the lifting of the ram, causing a sudden increase in load, the flow state of the oil inside the hydraulic torque converter 2 changes, and the output torque of the turbine automatically increases to adapt to the load change and prevent the motor 1 from overloaded and shutting down. At the same time, the planetary reducer 4 further amplifies the torque through gear transmission to ensure a smooth lifting process.

[0032] When the ram is lifted to a set height, such as 20m, the operator issues a hook-drop command through the control panel. The electromagnetic reversing valve reverses, the hydraulic system stops supplying oil to the normally open internal expansion clutch 7, the clutch disengages under the action of the reset spring, the planetary reducer 4 and the drum 5 are disconnected from power. At this time, the ram pulls the wire rope under its own weight, causing the drum 5 to rotate in the opposite direction, thus achieving free hook drop.

[0033] During the lowering process, the operator can adjust the hydraulic braking pressure of the caliper disc brake 8 via the control panel as needed. When it is necessary to decelerate or stop the lowering, the electromagnetic reversing valve supplies oil to the caliper disc brake 8, the brake caliper clamps the brake disc, generates braking torque, reduces the reverse speed of the drum 5 or stops it from rotating, thereby precisely controlling the lowering height of the hammer.

[0034] When the dynamic compaction machine completes a compaction operation or needs to be stopped:

[0035] Clutch kept disengaged: The hydraulic system stops supplying oil to the normally open internal expansion clutch 7, and the clutch remains disengaged to prevent the drum 5 from being accidentally connected to the power source.

[0036] Normally closed brake 6 braking: The hydraulic system simultaneously cuts off the oil supply to the normally closed brake 6. Under the action of the spring force, the brake clamps the brake disc and firmly locks the drum 5 to prevent the drum 5 from rotating due to unexpected factors, thus ensuring equipment safety.

[0037] In operation, the motor 1 outputs power, and the torque converter 2 connected to it adjusts the output torque in real time according to the load changes. The universal joint 3 is connected to the planetary reducer 4 inside the drum. The output shaft of the planetary reducer drives the normally open clutch 7. After the normally open clutch is closed, it drives the drum 5 to rotate to lift the hammer. When the normally open clutch releases pressure, the drum reverses under the weight of the hook, achieving free-fall of the hook. The caliper brake 8 brakes in time to control the lowering height of the hook. In non-operating state, the normally open clutch is open and the normally closed brake 6 is closed to prevent the drum from rotating. The normally open clutch 7, the caliper brake 8, and the normally closed brake 6 are controlled by a hydraulic system.

[0038] This invention utilizes a combination of electric motor 1 and torque converter 2 for drive, resulting in higher working efficiency.

[0039] Electric motor 1 is easier to control precisely, which is conducive to the intelligent development of dynamic compaction machines;

[0040] Energy conservation, emission reduction, and environmental protection;

[0041] The electric motor 1 has a simple structure and is easy to install and modify.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
