[0036] Due to the special use environment of cable cranes and the wide distance between the two spans of the main tower, it is inconvenient to power the trolley of the cable crane. With the development of the times, the safety regulations of relevant special equipment are becoming more and more stringent. In order to facilitate lifting, it is an inevitable trend to install travel encoders, position positioning sensors, wind speed detection, hook visualization, and speed sensors on the trolley of the cable crane. At the same time, for the sake of lifting safety, the requirements for adding some new safety monitoring equipment are becoming more and more urgent. Now the power distribution for the trolley of the cable crane is a problem that must be solved.

[0037] The market currently uses wind power and solar power to solve this problem, but the disadvantages are also obvious. It must be used according to the weather, and wind power generation is too easy to burn the generator, while the solar panels of solar power generation are too large.

[0038] The utility model provides a power generation device and a cable hanger, aiming to have a simple structure and strong adaptability, and can stably and reliably supply power to a trolley.

[0040] The technical solution of the utility model is to install the power generation device 100 on the trolley, so that when the trolley moves on the cable 200, the friction of the cable 200 drives the first friction wheel 3 to rotate, and through the setting of the transmission system 5, the rotation speed of the input shaft of the generator 4 is greater than the rotation speed of the first friction wheel 3, so as to achieve normal power generation. As long as the trolley is moving, the power generation device 100 can generate electricity independently of the weather conditions. The winch has overspeed protection, and the generator 4 will not be burned due to overspeed. There is no need for large solar panels, so the structure is simple and adaptable, and it can stably and reliably supply power to the trolley.

[0041] The utility model does not limit the specific form of the mounting frame 1. In one embodiment of the utility model, the mounting frame 1 includes a mounting plate 11 and a shield 12. The two mounting plates 11 are arranged opposite to each other and connected to each other. The first friction wheel 3, the generator 4 and the transmission system 5 are installed on the mounting plates 11. Two shields 12 are provided on the mounting plates 11 to protect the first friction wheel 3, the generator 4 and the transmission system 5.

[0042] In an embodiment of the utility model, the rotating shaft of the first friction wheel 3 and the rotating shaft of the generator 4 both extend longitudinally, the transmission system 5 includes a first synchronous pulley assembly 51, a gear transmission assembly 52, and a second synchronous pulley assembly 53, the first synchronous pulley assembly 51 includes a plurality of pulleys and a first synchronous belt 514 sleeved on the plurality of pulleys, the plurality of pulleys include a first driving wheel 511 and a first driven wheel 512, the number of teeth of the first driving wheel 511 is greater than the number of teeth of the first driven wheel 512, the first driving wheel 511 is coaxially connected to the first friction wheel 3; the gear transmission assembly 52 includes a driving gear 521 and a driven gear 522 meshing with each other, the number of teeth of the driving gear 521 is greater than the number of teeth of the driven gear 522, the driving gear 521 is coaxially connected to the first driven wheel 512; and the second synchronous pulley assembly 53 includes a second driving gear 521 and a driven gear 522 meshing with each other, the number of teeth of the driving gear 521 is greater than the number of teeth of the driven gear 522, the driving gear 521 is coaxially connected to the first driven wheel 512; The driven wheel 531, the second driven wheel 532, and the second synchronous belt 533 mounted on the second driving wheel 531 and the second driven wheel 532, the number of teeth of the second driving wheel 531 is greater than or equal to the number of teeth of the second driven wheel 532, the second driving wheel 531 is coaxially connected to the driven gear 522, and the second driven wheel 532 is coaxially connected to the input shaft of the generator 4. Through the arrangement of the first synchronous pulley assembly 51, the gear transmission assembly 52, and the second synchronous pulley assembly 53, not only can the motion be transmitted and the structural layout is convenient, but also the speed input of the generator 4 can be ensured through multi-stage acceleration. It can be understood that the normal driving speed of the trolley is generally 3M / min, and the normal lifting and lowering of the hook is also 3M / min. According to these parameters, the gear ratio is designed so that when the trolley is moving, the input shaft of the generator 4 can obtain a normal and effective speed, thereby generating electricity normally.

[0043] It should be noted that the transverse and longitudinal directions referred to in the present application do not specifically refer to two intersecting directions on the horizontal plane. The transverse direction refers to the approximate direction in which the cable 200 extends when the power generation device 100 is coordinated with the cable 200, and the longitudinal direction is a direction perpendicular to the transverse direction. When the posture of the power generation device 100 changes, the transverse and longitudinal directions also change accordingly.

[0044] In an embodiment of the utility model, two first friction wheels 3 are provided, and the two first friction wheels 3 are distributed at intervals in the lateral direction. Two first driving wheels 511 are provided, and are coaxially connected to the two first friction wheels 3. Two first friction wheels 3 are provided, and correspondingly, two first driving wheels 511 are provided, so that the friction force between the power generation device 100 and the cable 200 is more balanced, and the movement of the two first friction wheels 3 is better transmitted to the input shaft of the generator 4, so as to achieve more stable and reliable power generation.

[0045] In an embodiment of the utility model, the plurality of pulleys further include an additional pulley 513, the shaft of which is movably adjustable on the mounting frame 1 in a direction perpendicular to the extension direction of the shaft of which, that is, the distance between the additional pulley 513 and the first driving wheel 511 and / or the first driven wheel 512 is adjustable, and the tension of the first synchronous belt 514 can be adjusted by adjusting the shaft position of the additional pulley 513 to ensure the transmission effect of the first synchronous pulley assembly 51. Specifically, the shaft position of the additional pulley 513 can be adjusted by adjusting the first screw 9.

[0046] It can be understood that a groove can be provided on the outer circumference of the first friction wheel 3, and the cable 200 is inserted into the groove. Through reasonable position setting, the outer circumference of the first friction wheel 3 can be ensured to be in friction contact with the cable 200. In an embodiment of the utility model, the power generation device 100 also includes a second friction wheel 6 rotatably mounted on the mounting frame 1, and the second friction wheel 6 is correspondingly arranged with the first friction wheel 3, so that the first friction wheel 3 and the second friction wheel 6 are used to clamp the cable 200, and the outer circumference of the second friction wheel 6 is used to be in friction contact with the cable 200. In this way, through the setting of the second friction wheel 6, the cable 200 can be stably clamped between the first friction wheel 3 and the second friction wheel 6, ensuring the stable friction contact between the first friction wheel 3 and the cable 200, thereby improving the stable and reliable power generation of the power generation device 100.

[0047] In an embodiment of the utility model, the rotating shaft of the second friction wheel 6 extends longitudinally, and a plurality of second friction wheels 6 are provided, and the plurality of second friction wheels 6 are distributed at intervals in the transverse direction. It can be understood that the power generation device 100 moves with the trolley on the cable 200. The arrangement of the plurality of second friction wheels 6 can balance the force on the cable 200, reduce the influence of the arrangement of the power generation device 100 on the operation of the trolley, and achieve relatively stable and reliable power generation.

[0048] In an embodiment of the utility model, the rotating shaft of the second friction wheel 6 is movably adjustable and arranged on the mounting frame 1, so that the distance between the second friction wheel 6 and the first friction wheel 3 can be adjusted, so as to facilitate the adjustment of the distance between the second friction wheel 6 and the first friction wheel 3, thereby adjusting the friction between the first friction wheel 3 and the cable 200, thereby effectively converting mechanical energy into kinetic energy to ensure the power generation effect. Specifically, the position of the rotating shaft of the second friction wheel 6 is adjusted by adjusting the second screw 10.

[0049] In an embodiment of the utility model, the power generation device 100 also includes an energy storage battery (not shown in the figure), which is electrically connected to the output end of the generator 4. The energy storage battery can store excess electricity during low-peak power consumption of the vehicle and output it during peak power consumption. When the vehicle is not running, the energy storage battery can also continue to supply power to electrical devices on the vehicle to further ensure the reliability of power supply.

[0050] In an embodiment of the utility model, the mounting frame 1 has four first connecting parts respectively located at the four vertices of a quadrilateral (not shown in the figure, refer to the connection position of the connecting rope 8 for understanding), the power generation device 100 also includes an adapter frame 7 and four connecting ropes 8, the adapter frame 7 is used to be fixedly installed on the trolley, the adapter frame 7 is arranged around the periphery of the mounting frame 1, and the adapter frame 7 has four second connecting parts respectively located at the four vertices of another quadrilateral (not shown in the figure, refer to the connection position of the connecting rope 8 for understanding); one end of each of the connecting ropes 8 is connected to the first connecting part, and the other end of each of the connecting ropes 8 is connected to the corresponding second connecting part. The mounting frame 1 can be given a certain swing amplitude by being connected through the connecting ropes 8, and is then fixed to the trolley through the adapter frame 7, effectively preventing the cable 200 from jumping and damaging the first friction wheel 3 and the bearing in the first friction wheel 3 and / or the second friction wheel 6 and the bearing in the second friction wheel 6.

[0051] The utility model also proposes a cable crane, which includes a power generation device 100. The specific structure of the power generation device 100 refers to the above embodiment. Since the cable crane adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
