Description

Technical Field

[0001] The utility model relates to the technical field of lifting belt production, in particular to a tensioning coil pulling device for lifting belt production. Background Art

[0002] With the needs of social development, lifting belts are widely used in various fields, such as shipping, petroleum, transportation, chemical industry and other fields. There are many types of lifting belts. According to the appearance of the lifting belts, they are divided into four categories: annular core-through, annular flat, double-eye core-through, and double-eye flat; according to the maximum load that can be safely tolerated, they can be divided into 1T load lifting belts, 2T load lifting belts and 3T load lifting belts, etc. When producing lifting belts, the manual pulling force is small and unstable, so a tensioning coil pulling device is required.

The utility model utilizes the input roller, the first tensioning roller and the second tensioning roller arranged in a triangle to achieve the pulling of the prefabricated lifting belt, which is efficient, time-saving and labor-saving; at the same time, the first tensioning gear and the second tensioning gear of different diameters are used to increase the pulling force on the prefabricated lifting belt, so as to reduce or eliminate wrinkles on the prefabricated lifting belt.

Two sections of threaded wires with opposite rotation directions are fixed on the outer side of the rotating rod 3, and the movable block 4 is threadedly connected to the rotating rod 3.

[0023] It can be understood that the setting of opposite thread lines is conducive to the relative or opposite movement of the connecting seat 6, thereby facilitating the adjustment of the tensioning function and improving the use effect of the entire device.

[0024] It can also be understood that the bottom of the two movable blocks 4 is fixed with a sliding block 5 movably connected to the top of the base plate 1. A sliding channel is opened on the top of the base plate 1, and the sliding block 5 is slidably connected to the base plate 1 through the sliding channel.

[0025] It can be found that the provision of the sliding channel is conducive to the stable sliding of the sliding block 5, thereby facilitating the stable use of the entire device and improving the use effect of the device.

[0026] A movable component is provided on the top of the two movable blocks 4. A detector 7 is fixed on the top of the left movable component, and a receiving plate 8 is fixed on the top of the right movable component. A lifting cylinder 9 is fixed on the movable component.

[0027] It can also be found that the setting of the detector 7 and the receiving plate 8 is conducive to controlling the distance between the connecting seats 6 of the two, thereby facilitating the control of the tensioning state of the device. The servo motor 2 supplies energy to drive the movement of the movable component, thereby facilitating the adjustment of the tensioning state and improving the use effect of the device.

[0028] It should be explained that the movable component includes a connecting seat 6 fixed to the top of the movable block 4, and the inner side of the connecting seat 6 is movably connected to a connecting plate 10. The top of the connecting seat 6 is provided with a movable opening extending to the inner side of the connecting seat 6, and the connecting plate 10 is slidably connected to the connecting seat 6 through the movable opening.

[0030] A limiting opening communicating with the movable opening is provided on the top of the connecting seat 6 , and limiting strips are fixed on both the front and rear sides of the connecting plate 10 , and the limiting strips are slidably connected to the connecting seat 6 through the limiting opening.

[0031] The setting of the limiting opening is conducive to the sliding of the limiting bar, thereby further improving the stable use of the entire movable component.

[0032] It is not difficult to understand that a support spring located in the limit opening is fixed between the bottom of the connecting plate 10 and the connecting seat 6, a connecting plate 11 is fixed on the right side of the connecting plate 10, a movable cylinder 12 is fixed on the top of the connecting plate 11, and the movable axis of the lifting cylinder 9 is fixed to the bottom of the connecting plate 10.

The tensioning component 13 is controlled by the lifting cylinder 9, thereby further improving the tensioning state of the device. The tensioning component 13 is driven to operate by the movable cylinder 12, thereby further improving the tension adjustment capability of the device.

[0034] See also Figure 3 In order to improve the ability to adjust the tensioning state, the tensioning assembly 13 in this embodiment includes a fixed block 1301 fixed to the top of the connecting plate 11, a fixed cylinder 1302 is fixed to the back of the fixed block 1301, and a movable column 1303 movably connected to the fixed cylinder 1302 is fixed to the movable shaft of the movable cylinder 12. A movable opening that penetrates into the inner side of the fixed cylinder 1302 is opened on the left side of the fixed block 1301, and the movable column 1303 is slidably connected to the fixed cylinder 1302 through the movable opening.

[0035] It is also easy to understand that the setting of the sliding opening facilitates the adjustment of the movable column 1303 through the movable cylinder 12, thereby facilitating the movement of the movable plate 1306, and further facilitating the operation of the component, thereby facilitating the improvement of the overall stability of use.

[0037] The setting of the movable channel is conducive to the sliding of the ring plate 1304, which is conducive to adjusting the tension state of the lifting belt, improving the stability of the component movement, and thus facilitating the stable use of the entire device, and further improving the adjustment ability of the tension state.

[0038] The inner side of the ring plate 1304 is hinged with a hinge rod 1305, and the outer side of the movable column 1303 is fixed with a movable plate 1306.

The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0041] The working principle of the above embodiment is:

[0042] The lifting belt is wrapped and connected through the outer side of the ring plate 1304 in different tensioning assemblies 13, and the servo motor 2 is started to drive the rotating rod 3 to rotate, and the movable block 4 is driven to move through the threaded connection, driving the connecting seats 6 on both sides to slide relative to or away from each other, and the receiving plate 8 is measured by the detector 7 to control the distance between the connecting seats 6, so that the tensioning state of the lifting belt between the two tensioning assemblies 13 is adjusted, and the lifting cylinder 9 is started to drive the connecting plate 10 to rise and fall, thereby realizing the height adjustment of the tensioning assembly 13, realizing further adjustment of the tensioning state of the lifting belt, and regulating the connection angle of the lifting belt at the same time.
