Description

[0035] Combination Figure 1-5 As shown, this disclosure provides a winch tension, length measurement, and rope delivery device, comprising:

[0036] The main body 1-1 is the main structure, fixed to the left support plate 1-5 and the right support plate 1-2 by support rods 1-6. The left support plate 1-5 and the right support plate 1-2 have evenly distributed screw holes at their connection points with the winch drum, arranged in a circular pattern. Fasteners 1-3 pass through these screw holes to fix the left support plate 1-5 and the right support plate 1-2 to the winch drum respectively. By installing fasteners 1-3 on different screw holes, the rope exit angle can be changed (see details). Figure 5 (As shown).

[0037] Reference Figure 3 and Figure 4 As shown, the main body 1-1 of the device includes: a lower pulley 2-1, a cover 2-2, an upper pulley 2-3, a side plate 2-4; a wire rope 2-5, a side cover 2-6, a movable pulley mounting side plate 2-7, a force sensor mounting base 2-8, a force sensor 2-9, a force sensor mounting plate 2-10, a rope pressing wheel 2-11, a compression spring 2-12, a rope pressing wheel shaft 2-13, a fixing component 2-14, a movable pulley 2-15, a pulley shaft 2-16, a coupling 2-17, and a length measuring component 2-18;

[0038] Among them, cover 2-2 and side cover 2-6 are used for axial positioning during the installation of upper pulley 2-3, lower pulley 2-1 and movable pulley 2-15.

[0039] In this embodiment, the force sensor 2-9 is mounted on the force sensor mounting plate 2-10 by the fastener 2-14, and the force sensor mounting base 2-8 is connected to the force sensor mounting plate 2-10 by fasteners; the force sensor mounting base 2-8 is mounted on the two side plates 2-4.

[0040] The lower pulley 2-1 and upper pulley 2-3 are mounted on the side plate 2-4; the movable pulley 2-15 is mounted on the movable pulley mounting side plate 2-7 via the pulley shaft 2-16. The movable pulley mounting side plate 2-7 slides within the groove of the side plate 2-4, and the end face of the movable pulley mounting side plate 2-7 contacts the force sensor 2-9. The movable pulley mounting side plate 2-7 and the movable pulley 2-15 can move a small distance when the wire rope 2-5 is under force. The force on the movable pulley 2-15 is transmitted to the force sensor 2-9 through the pulley shaft 2-16, so that the force sensor 2-9 can collect the force information, thereby indirectly collecting the force information of the wire rope 2-5 exiting the rope. The force sensor 2-9 uploads the collected information to the controller for processing and calculation of the force information.

[0041] The movable pulley 2-15 is connected to the pulley shaft 2-16 via a key; the length measuring component 2-18 is connected to the pulley shaft 2-16 of the movable pulley 2-15 via a coupling 2-17. The movement of the wire rope 2-5 causes the movable pulley 2-15 to rotate. The length measuring component 2-18, connected to the movable pulley 2-15, can collect the rotation length information of the movable pulley, thereby indirectly collecting the information of the wire rope 2-5 exiting the drum. The length measuring component 2-18 is an encoder that rotates synchronously with the movable pulley 2-15, converting the rotation angle and number of turns into electrical pulse signals and outputting them to the controller. The controller calculates the rotation length of the pulley based on the number of pulses, the encoder resolution, and the pulley circumference.

[0042] The drive shaft 1-7 is fixed at both ends to the left support plate 1-5 and the right support plate 1-2 respectively, and is connected to the lower pulley 2-1 of the device body 1-1. The drive shaft 1-7 is equipped with a drive key and a one-way bearing, and is connected to the upper drive sprocket 1-4 of the drum. The sprocket of the drum is connected to the upper drive sprocket 1-4 through a chain, so that the rotation of the drum is transmitted to the drive shaft 1-7 and the lower pulley 2-1.

[0043] The transmission from the drum to the drive shaft 1-7 is based on the requirement that the linear speed of the wire rope 2-5 on the pulley is slightly faster than the speed at which the wire rope 2-5 exits the drum. This causes the wire rope 2-5 to exit under the frictional drive of the pulley and the pressure wheel 2-11. The pressure wheel 2-11 acts to pull the wire rope 2-5 out of the drum under a certain tension, thus achieving the function of rope exit. The pressure wheel 2-11 is mounted on the pressure wheel shaft 2-13, which is installed in a groove on the side plate 2-4. Under the action of the compression spring 2-12, it moves within the groove on the side plate 2-4. The pressure of the pressure wheel 2-11 on the wire rope 2-5 can be adjusted by adjusting the compression length of the compression spring 2-12.

[0044] The working principle of this device is as follows:

[0045] The main body 1-1 of the winch tension, length measurement and rope delivery device is installed on the upper or front side of the winch drum via the drive shaft 1-7, support rod 1-6, left support plate 1-5, and right support plate 1-2. By loosening the fasteners and adjusting the connection angle between the main body 1-1 and the drum, and then passing the fastener 1-3 through the screw hole at that angle, the rope delivery angle can be changed. After adjusting to the appropriate angle, tightening the fastener 1-3 will meet the requirements of the winch rope delivery angle from horizontal to vertical. The wire rope 2-5 on the drum passes through the lower pulley 2-1, the rope pressing pulley 2-11, the movable pulley 2-15, and the upper pulley 2-3 before exiting. When the wire rope 2-5 is subjected to tension, this force causes the movable pulley 2-15 to bear force. Since the movable pulley 2-15 is mounted on the pulley shaft 2-16, which in turn is mounted on the movable pulley mounting side plate 2-7, the movable pulley mounting side plate 2-7 can slide within the groove of the side plate 2-4. The force on the end face of the movable pulley mounting side plate 2-7 acts on the force sensor 2-9, allowing the force sensor 2-9 to collect force information, thereby indirectly collecting the force information of the wire rope 2-5 exiting the drum. Simultaneously, the movable pulley 2-15 rotates under the frictional force of the wire rope 2-5. This rotation enables real-time measurement of the winch wire rope length through the pulley shaft 2-16, the coupling 2-17, and the length measuring component 2-18. Meanwhile, the rope delivery device, consisting of drive shaft 1-7, lower pulley 2-1, rope pressing wheel 2-11, movable pulley 2-15, and upper pulley 2-3, ensures that the wire rope near the drum is delivered in a timely manner, preventing the drum from becoming tangled, which is beneficial to the safety of lifting heavy loads and can also protect the wire rope.
