[0063] The driving assembly 20 is arranged in the containing cavity 11, and the driving assembly 20 comprises a driving part 21 and a winch mechanism 22.

The driving part 21 can be a motor, which is used to generate driving force. The motor can be a three-phase asynchronous motor or a servo motor, and the motor can select different power and speed according to needs. A speed reducer can also be connected to the motor, which is used to reduce the speed and increase the torque, so that the power is more suitable for driving the winch mechanism 22 to work.

[0064] When the operator presses the start button, the power supply is sent to the motor, and the motor starts to rotate. The motor transmits power to the reducer through the shaft coupling. The reducer reduces the speed of the motor with low torque and converts it into high torque suitable for the use of the hoisting mechanism 22.

The main control unit can also be connected with a communication module, which is used for realizing data exchange with a superior system, such as an ERP and a SCADA.

[0066] The various components in the control assembly 30 are connected with each other through hardwiring, data lines or wireless means to form a unified electrical control system. The main control unit, as the core component, collects data from the sensors, analyzes the instructions of the operator, adjusts the speed and torque of the motor through the frequency converter, and monitors the state of the safety device at the same time, so as to ensure that the whole material lifting process is carried out according to the established procedure, while keeping a timely response to unexpected situations.

[0078] Figure 8 is a partial structure schematic view of another embodiment of the locking mechanism provided in the embodiment of the utility model. Figure 9 is Figure 8 is a sectional view of the locking mechanism.

[0079] Referring to Figure 8 and Figure 9 In some embodiments of the utility model, the locking mechanism 15 comprises a locking hook 154, a second elastic member 155 and a second unlocking member 156.

[0080] The locking portion 121 is provided with a handle slot 1212, that is, the locking portion 121 in the embodiment is not provided with a locking notch 1211. The locking hook 154 and the second unlocking member 156 are both arranged on the locking portion 121 through corresponding rotating shafts. The second unlocking member 156 is a plate-shaped member, and the second unlocking member 156 is located above the handle slot 1212. One end of the second unlocking member 156 forms a locking end, and the other end of the second unlocking member 156 forms an unlocking end.

[0082] The locking mechanism 15 provided in the embodiment is in the unlocking state, the second unlocking member 156 is away from the rotating path of the locking hook 154, and the second elastic member 155 is in the deformed state.

[0083] It should be noted that the locking hook 154 provided in the embodiment has an opening side and a counterweight side. When in the unlocking state, the opening side of the locking hook 154 faces downward, but when locking is needed, the counterweight side needs to be pressed, so that the opening side of the locking hook 154 overcomes the gravity and is opened. When the locking hook 154 is hung on the support carrier (such as a support pipe or a step roller 101 on the ladder 100), the locking hook 154 naturally faces downward due to the gravity, and the opening is in the most difficult-to-open position.

[0086] When the locking mechanism 15 is hung on the support pipe or the step roller 101 on the ladder 100, external force needs to be used, such as manual operation, to overcome the elastic force of the third elastic member 157 and the gravity of the opening side of the locking hook 154, so that the opening is temporarily enlarged to be clamped into the support pipe or the step roller 101 on the ladder 100. When the locking mechanism 15 is locked in place, the locking hook 154 naturally falls back to the locking state due to the gravity, the opening is resealed, and a firm locking effect is formed. At the same time, the third elastic member 157 provides a certain action for locking, so that the locking effect of the locking mechanism 15 is better.

[0087] The locking mechanism 15 provided by the embodiment of the utility model will not open automatically unless it is intentionally unlocked, and can provide continuous security. Even in the case of power or other energy interruption, the gravity locking is still effective, does not depend on the electronic system, the structure is relatively simple, easy to maintain, can maintain high performance in harsh environments, uses the earth's gravity to make the locking mechanism 15 realize the efficient and low-cost automatic locking mode.

The rope detection component 62 is arranged in the shell assembly 10 and is located on the rotating path of the rope protection component 61, and the rope detection component 62 is connected in the control loop of the control assembly 30.

[0091] Further, the rope protection component 61 includes a mounting frame body 611, a first shaft body 612, a second shaft body 613, a reset member 614 and a trigger member 615, the first shaft body 612 is fixedly connected to one end of the mounting frame body 611, the second shaft body 613 is fixedly connected to the other end of the mounting frame body 611, and the first shaft body 612 and the second shaft body 613 are rotatably connected with the shell assembly 10.

[0093] The trigger member 615 is arranged on the first shaft body 612 or the second shaft body 613 and is adapted to rotate with the corresponding shaft body to trigger the loose rope detection component 62. The arrangement position of the trigger member 615 is determined according to the installation position of the loose rope detection component 62. For example, when the loose rope detection component 62 is installed on the rotation path of the first shaft body 612, the trigger member 615 is installed on the first shaft body 612.

[0094] Two rollers 616 are arranged on the mounting frame body 611 at intervals, the traction rope is arranged between the two rollers 616, the rollers 616 are tensioned by the tension of the traction rope, the mounting frame body 611 and the first shaft body 612 and the second shaft body 613 fixedly connected to the mounting frame body 611 are driven to rotate by the rollers 616, the reset member 614 is in an elastic deformation state, that is, the reset member 614 has the capability of restoring the elastic deformation, and at this time, the trigger member 615 does not trigger the loose rope detection component 62.

[0095] When the traction rope 201 loses the tension due to various reasons (such as breakage, wear, improper operation, etc.), the reset member 614 restores the elastic deformation to drive the first shaft body 612, the second shaft body 613 and the mounting frame body 611 to rotate as a whole, so that the trigger member 615 triggers the loose rope detection component 62 to act, the loose rope detection component 62 cuts off the circuit to prevent the traction device 200 from descending, thereby providing safety protection for the traction device 200.

[0096] When the traction rope 201 is in a taut state, the mounting frame body 611 and the rollers 616 are driven away from the shell assembly 10 by the traction rope 201 and simultaneously drive the trigger member 615 away from the loose rope detection component 62. At this time, the moment of force of the traction rope 201 on the rollers 616 and the moment of force of the reset member 614 on the rollers 616 reach a dynamic balance, and the rollers 616 guide the traction rope 201 to be normally wound and unwound.
