[0002] The ship unloader is a new type of continuous ship unloading equipment with the characteristics of energy saving, high efficiency and environmental protection, which fully meets the development requirements of low-carbon economy.

[0003] The chain bucket ship unloader of the prior art generally realizes the lifting of the material taking mechanism through the luffing movement of the girder assembly, so as to dig different height materials, but due to the limited luffing height of the girder assembly, the working efficiency of the ship unloader is low. Further, due to the large weight of the girder assembly, and the material carried during the lifting of the girder, the driving mechanism for driving the girder assembly to move up and down needs to provide a large power, resulting in the increase of the use cost of the driving mechanism. In addition, due to the uneven weight distribution of the structure on the girder assembly, the ship unloader is prone to have a high overturning risk, and in the process of conveying the material, the ship unloader is usually impacted by the surge, which further causes the collision between the material taking mechanism and other mechanisms, thereby affecting the normal operation of the ship unloader.

DETAILED DESCRIPTION

[0047] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts should fall into the scope of the present application.

[0048] In view of the problems of high use cost of the driving mechanism, low material taking efficiency caused by the adjustment of the pitch mechanism, large overturning moment caused by uneven weight distribution of the beam assembly structure, and damage of the material taking mechanism caused by sea waves, the present application provides a ship unloader.

[0049] The embodiments of the present application will be described below in combination with Figures 1 to 10 .

[0050] According to the embodiments of the present application, as shown in Figure 1 and Figure 3 , a ship unloader is provided, comprising a tower support 1, a sleeve support 2, a beam support assembly, a first driving mechanism 4, a counterweight mechanism 5, a material taking mechanism 6 and a first conveying mechanism.

[0051] Specifically, the tower support 1 is provided with a central through hole in the height direction thereof, and the tower support 1 is adapted to be installed on the ground; the sleeve support 2 is sleeved on the tower support 1 and is in sliding connection with the tower support 1; the beam support assembly is arranged on the sleeve support 2 and extends away from the sleeve support 2; the first driving mechanism 4 is arranged on the beam support assembly and is adapted to drive the sleeve support 2 to slide on the tower support 1; the counterweight mechanism 5 is arranged in the central through hole and is connected with the sleeve support 2 through a flexible cable; the material taking mechanism 6 is arranged on the beam support assembly through a slewing device and is provided with a material taking port and a material discharging port, and a first oil cylinder 601 arranged horizontally and a second oil cylinder 602 arranged vertically are arranged on one end of the material taking port of the material taking mechanism 6; the first conveying mechanism is arranged on the beam support assembly and is provided with a material feeding end and a material discharging end, and the material feeding end of the first conveying mechanism is connected with the material discharging port of the material taking mechanism 6.

[0052] The embodiment of the present application can drive the sleeve frame 2 to slide by connecting the sleeve frame 2 with the tower frame 1 and driving the sleeve frame 2 to slide by the first driving mechanism 4, so that the sleeve frame 2 can drive the beam frame assembly and the material taking mechanism 6 to lift, thereby enabling the material taking mechanism 6 to take materials at different heights and improving the working efficiency of the material taking mechanism 6; the counterweight mechanism 5 is arranged to balance the weight of the beam frame assembly and the structure arranged on the beam frame assembly, thereby reducing the power required for the first driving mechanism 4 to drive the sleeve frame 2 to slide on the tower frame 1, reducing the use cost of the first driving mechanism 4, and reducing the overturning moment of the beam frame assembly acting on the sleeve frame 2, thereby improving the reliability. Further, the first oil cylinder 601 arranged horizontally and the second oil cylinder 602 arranged vertically at one end of the material taking port of the material taking mechanism 6 can absorb the horizontal or vertical force generated by the surge on the material taking mechanism 6, thereby reducing the influence on the material taking mechanism 6. In addition, the rotary device is arranged to enable the material taking mechanism 6 to rotate freely in the horizontal direction relative to the beam frame assembly, thereby enabling the material taking port of the material taking mechanism 6 to always face the material to be taken, improving the filling rate of the material taking port of the material taking mechanism 6 during the material taking process, and improving the working efficiency of the ship unloader as a whole.

[0053] It should be noted that when the material taking mechanism 6 normally takes materials, the first oil cylinder 601 and the second oil cylinder 602 at the material taking port of the material taking mechanism 6 are in an extended state, at this time the counterweight mechanism 5 gives the beam frame assembly an upward lifting force, which can offset part of the gravity of the beam frame assembly and the material taking mechanism 6. If a surge impact is encountered, the material taking port of the material taking mechanism 6 will first be impacted, after the material taking port of the material taking mechanism 6 is impacted, if the impact force exceeds the pressure setting value of the first oil cylinder 601 and the second oil cylinder 602, the oil cylinder in the corresponding direction will be retracted, thereby reducing the surge impact on the material taking mechanism 6.

[0054] In one example, as shown in Figure 7 The column of the tower frame 1 is provided with a sliding track arranged in the height direction of the tower frame 1, and the sleeve frame 2 is provided with a roller 201 adapted to slide on the sliding track. In the present embodiment, the tower frame 1 has a cuboid shape, the sliding track is arranged on the columns of the tower frame 1 which are opposite to each other, the sleeve frame 2 also has a cuboid shape, a through hole adapted to the tower frame 1 is formed in the sleeve frame 2, and the roller 201 corresponding to the sliding track is arranged in the sleeve frame 2. It can be understood that the height of the sleeve frame 2 needs to be less than the height of the tower frame 1.

[0055] According to one embodiment of the present application, as shown in Figure 1As shown, the cross beam support assembly comprises a first cross beam 301 and a second cross beam 302 arranged on opposite sides of the sleeve support 2; the first cross beam 301 is provided with a first conveying mechanism, a material taking mechanism 6 and a rotating device, and the second cross beam 302 is provided with a first driving mechanism 4. It can be understood that in the present embodiment, the sleeve support 2 is driven to slide up and down on the tower support 1 by the first driving mechanism 4 arranged on the second cross beam 302, so that the discharge end of the first conveying mechanism can move up and down along the height direction of the tower support 1, thereby realizing material taking operation at different heights.

[0056] In the present embodiment, the material taking mechanism 6 and the rotating device are arranged on the first cross beam 301 through a material taking head trolley 603, wherein the material taking head trolley 603 can drive the material taking mechanism 6 to make rapid linear reciprocating motion in the length direction of the first cross beam 301, thereby increasing the working range of the material taking mechanism 6 to adapt to the needs of different working conditions and improve the working efficiency of the ship unloader.

[0057] In one example, as shown in Figure 9 The first conveying mechanism comprises a scraper 701 and a belt conveyor 702; one end of the scraper 701 is located below the discharge port of the material taking mechanism 6, one end of the scraper 701 is located above the belt conveyor 702, and the conveying direction of the scraper 701 is perpendicular to the extension direction of the belt conveyor 702. In the present embodiment, the scraper 701 is arranged to effectively connect the discharge port of the material taking mechanism 6 with the belt conveyor 702, thereby ensuring the continuity of material transportation.

[0058] According to one embodiment of the present application, as shown in Figure 2 The end surface of the sleeve support 2 facing the first cross beam 301 is provided with a pair of oppositely arranged first pulley sets 202; the end surface of the sleeve support 2 facing the second cross beam 302 is provided with a pair of oppositely arranged second pulley sets 203; the upper end surface of the tower support 1 is provided with a pair of oppositely arranged third pulley sets 101 near one side of the first pulley sets 202 and a pair of oppositely arranged fourth pulley sets 102 near the other side of the second pulley sets 203; the first driving mechanism 4 is connected to one of the second pulley sets 203, one of the fourth pulley sets 102, one of the third pulley sets 101 and one of the first pulley sets 202 through a flexible cable, and is connected to the other first pulley set 202, the other third pulley set 101, the other fourth pulley set 102 and the other second pulley set 203, and is connected back to the first driving mechanism 4. In the present embodiment, the pulleys on the tower support 1 and the sleeve support 2 are connected by the flexible cable, so that the power of the first driving mechanism 4 can be effectively transmitted to each pulley, thereby driving the sleeve support 2 to reciprocate on the tower support 1.

[0059] It should be noted that the first driving mechanism 4 can be one or two winding drums. As shown in Figure 4As shown, taking the connection relationship of the flexible cable of two winding drums as an example, the two winding drums are arranged at the end of the second cross beam 302 away from the sleeve support 2, one of the winding drums is connected to one of the second pulley sets 203, one of the fourth pulley sets 102, one of the third pulley sets 101 and one of the first pulley sets 202 through the flexible cable in sequence, and is connected to the other first pulley set 202, the other third pulley set 101, the other fourth pulley set 102 and the other second pulley set 203, and is connected back to the other winding drum. It can be understood that when the two winding drums simultaneously wind the flexible cable, the sleeve support 2 drives the cross beam support assembly to ascend along the height direction of the tower support 1; when the two winding drums simultaneously release the flexible cable, the sleeve support 2 drives the cross beam support assembly to descend along the height direction of the tower support 1.

[0060] According to an embodiment of the present application, as shown in Figure 1 and Figure 7 The counterweight mechanism 5 includes a first counterweight assembly and a second counterweight assembly; the first counterweight assembly includes a first counterweight 501 and a first counterweight pulley assembly; the first counterweight pulley assembly is connected to the sleeve support 2 and the first counterweight 501 through the flexible cable respectively; the second counterweight assembly includes a second counterweight 502 and a second counterweight pulley assembly; the second counterweight pulley assembly is connected to the sleeve support 2 and the second counterweight 502 through the flexible cable respectively. In this embodiment, the first counterweight assembly balances the weight of the first cross beam 301, the material taking mechanism 6 and the first conveying mechanism, and the second counterweight assembly balances the weight of the second cross beam 302 and the first driving mechanism 4, which can reduce the power required by the first driving mechanism 4 to drive the sleeve support 2 to slide on the tower support 1, and reduces the use cost of the first driving mechanism.

[0061] According to an embodiment of the present application, as shown in Figure 2 , Figure 5 and Figure 6As shown, the third pulley set 101 is arranged on the upper end of the tower support 1 near the first cross beam 301 through the first support column 1011, and the fourth pulley set 102 is arranged on the upper end of the tower support 1 near the second cross beam 302 through the second support column 1021; the first counterweight pulley assembly includes a first sub-counterweight pulley set 503, a second sub-counterweight pulley set 504, and a third sub-counterweight pulley set 505; the first sub-counterweight pulley set 503 is arranged on the upper end of the sleeve support 2 near the first cross beam 301, the second sub-counterweight pulley set 504 is arranged on the upper surface of the tower support 1 through the third support column 5041, and the third sub-counterweight pulley set 505 is arranged on the upper end of the first counterweight 501; the first support column 1011 is sequentially connected with the first sub-counterweight pulley set 503, the third pulley set 101, the second sub-counterweight pulley set 504, and the third sub-counterweight pulley set 505 through the flexible cable, and then the flexible cable is fixed to the third support column 5041. Through the position layout of the first sub-counterweight pulley set 503, the second sub-counterweight pulley set 504, the third sub-counterweight pulley set 505, and the third pulley set 101, the flexible cable can act on the side of the sleeve support 2 provided with the first cross beam 301, the layout is reasonable, and the installation difficulty of the first counterweight 501 is reduced.

[0062] In addition, the second counterweight pulley assembly includes a fourth sub-counterweight pulley set 506 and a fifth sub-counterweight pulley set 507; the fourth sub-counterweight pulley set 506 is arranged on the upper end of the sleeve support 2 near the second cross beam 302, and the fifth sub-counterweight pulley set 507 is arranged on the upper end of the second counterweight 502; the second support column 1021 is sequentially connected with the fourth sub-counterweight pulley set 506, the fourth pulley set 102, the second sub-counterweight pulley set 504, and the fifth sub-counterweight pulley set 507 through the flexible cable, and then the flexible cable is fixed to the third support column 5041. In this embodiment, through the position layout of the fourth sub-counterweight pulley set 506, the fifth sub-counterweight pulley set 507, and the fourth pulley set 102, the flexible cable can act on the side of the sleeve support 2 provided with the second cross beam 302, the layout is reasonable, and the installation difficulty of the second counterweight 502 is reduced. It can be understood that the first counterweight 501 and the second counterweight 502 jointly use the second sub-counterweight pulley set 504 and the third support column 5041, which can reduce the use cost of the set pulley, and is conducive to popularization.

[0063] It can be understood that when the sleeve support 2 rises relative to the tower support 1, the first counterweight 501 and the second counterweight 502 can descend under the action of their own gravity and the flexible cable, so as to balance the weight of the first cross beam 301, the weight of the second cross beam 302, the weight of the first conveying mechanism, the weight of the material taking mechanism 6, and the weight of the material on the material taking mechanism 6, thereby reducing the required power when the first driving mechanism 4 is driven, and reducing the use cost of the first driving mechanism 4.

[0064] It should be noted that the first pulley set 202, the second pulley set 203, the third pulley set 101, the fourth pulley set 102, the first sub-counterweight pulley set 503, the second sub-counterweight pulley set 504, the third sub-counterweight pulley set 505, the fourth sub-counterweight pulley set 506, and the fifth sub-counterweight pulley set 507 are all composed of multiple pulleys. The first counterweight 501 and the second counterweight 502 share the second sub-counterweight pulley set 504, which means that different pulleys in the second sub-counterweight pulley set 504 are connected to the first counterweight 501 and the first counterweight 501 respectively, rather than the same pulley connecting the first counterweight 501 and the second counterweight 502 simultaneously. Similarly, when the first counterweight 501 and the first driving mechanism 4 share the third pulley set 101, different pulleys on the third pulley set 101 are connected to the first counterweight 501 and the first driving mechanism 4 respectively; when the second counterweight 502 and the first driving mechanism 4 share the fourth pulley set 102, different pulleys on the fourth pulley set 102 are connected to the second counterweight 502 and the first driving mechanism 4 respectively.

[0065] In addition, the number of pulleys in each pulley set needs to be calculated according to factors such as the height of the tower support 1, the weight of the first cross beam 301, the weight of the second cross beam 302, and the weight of the material taking mechanism 6, so as to ensure that the first counterweight 501 and the second counterweight 502 can effectively balance the weight of the first cross beam 301, the weight of the second cross beam 302, and the weight of the first conveying mechanism and the material taking mechanism 6. In addition, by setting the number of pulleys in each pulley set and the winding method of the flexible cable, it can also prevent the stroke of the first counterweight 501 and the second counterweight 502 from being too long, causing the first counterweight 501 and the second counterweight 502 to touch the bottom of the tower support 1 and cause damage. It should be noted that the flexible cable in the embodiment of the present application can be a steel wire rope.

[0066] According to one embodiment of the present application, two groups of first counterweight assemblies are symmetrically installed on both sides of the tower support 2 along the length direction of the first cross beam 301, which can evenly share the weight of the first cross beam 301, the material taking mechanism 6, and the first conveying mechanism, avoiding excessive stress on the flexible cable and causing the risk of breakage. Two groups of second counterweight assemblies are symmetrically installed on both sides of the tower support 2 along the length direction of the second cross beam 302, which can evenly share the weight of the second cross beam 302 and the first driving mechanism 4, avoiding excessive stress on the flexible cable and causing the risk of breakage.

[0067] According to one embodiment of the present application, as shown in Figure 7 The two groups of first counterweights 501 and the two groups of second counterweights 502 are diagonally distributed in the center through hole, and the weight distribution is uniform, which can reduce the overturning moment of the weight of the first counterweight 501 and the weight of the second counterweight 502 to the tower support 2, and improve the overall structural stability.

[0068] Considering that the material taking mechanism 6 is installed on the first cross beam 301, the overturning moment of the tower support near the side of the first cross beam 301 is greater than that of the second cross beam 302, in order to better reduce the overturning moment of the tower support 1, the weight of the first counterweight 501 is adapted to the weight of the first cross beam 301 and the weight of the material taking mechanism 6, and the weight of the second counterweight 502 is adapted to the weight of the second cross beam 302. The weight of the first counterweight 501 is greater than the weight of the second counterweight 502.

[0069] According to one embodiment of the present application, as shown in Figure 1 and Figure 8 The ship unloader further comprises a chute guide mechanism 8 connected with the first conveying mechanism, and the chute guide mechanism 8 comprises a chute body and a feeding port assembly; the chute body is internally provided with a guide channel 801; the feeding port assembly is arranged on the side wall of the chute body and is connected with the guide channel 801, and the feeding port assembly comprises a first end face 802 and a second end face 803 arranged opposite along the height direction of the chute body, and a plurality of elastic baffle 804 assemblies are arranged between the first end face 802 and the second end face 803; the plurality of elastic baffle 804 assemblies can close the feeding port assembly, and each elastic baffle 804 assembly comprises a pair of elastic baffles 804 arranged opposite on the first end face 802 and the second end face 803 and lapped with each other; the discharge end of the first conveying mechanism is movably arranged between the pair of elastic baffles 804, and is adapted to open the feeding port assembly, so that the discharge end of the first conveying mechanism is connected with the guide channel 801.

[0070] The embodiment of the present application can block the connection between the guide channel 801 and the feeding port assembly by arranging a plurality of elastic baffle 804 assemblies on the side wall of the chute body, thereby reducing the leakage of materials during the conveying process. Furthermore, by utilizing the collapsible characteristics of the elastic baffle 804 assembly, the relative position of the discharge end of the first conveying mechanism between the first end face 802 and the second end face 803 can be adjusted according to the requirements under different working conditions, so as to realize the opening and closing of the feeding port assembly locally.

[0071] It can be understood that when it is required to make a certain position of the feeding port assembly communicate with the material guiding channel 801, the discharge end of the first conveying mechanism is only required to be moved to the position, and the elastic baffle 804 in contact with the discharge end of the first conveying mechanism and located on both sides of the discharge end of the first conveying mechanism is moved towards the first end surface 802 or the second end surface 803 connected therewith, further, the acting force between the discharge end of the first conveying mechanism and the elastic baffle 804 can also fix the discharge end of the first conveying mechanism, which helps to avoid the shaking or mispositioning of the discharge end of the first conveying mechanism in the material conveying process, and ensures the stable transportation of the material. When it is required to disconnect the communication between a certain position of the feeding port assembly and the material guiding channel 801, the discharge end of the first conveying mechanism is only required to be moved away from the position, and the compressed elastic baffle 804 is gradually restored to the original state by using the collapsible property of the elastic baffle 804 assembly, so as to re-close the communication passage between the feeding port assembly and the material guiding channel 801.

[0072] In a specific embodiment, as shown in Figure 8 the elastic baffle 804 comprises an elastic piece 8041 and an arc-shaped plate 8042, one end of the elastic piece 8041 is arranged on the first end surface 802 or the second end surface 803, and the other end is connected with the arc-shaped plate 8042, and the end away from the elastic piece 8041 of the arc-shaped plate 8042 is an arc-shaped end surface, that is, the arc-shaped end surface of the arc-shaped plate 8042 is in contact with the outer wall of the discharge end of the first conveying mechanism. In the present embodiment, the elastic baffle 804 can make the movement of the discharge end of the first conveying mechanism between the first end surface 802 and the second end surface 803 more smooth by using the arc-shaped plate 8042, and avoid the jamming situation that the discharge end of the first conveying mechanism cannot compress the elastic baffle 804. It should be noted that the elastic piece 8041 can be a spring in the present embodiment.

[0073] According to an embodiment of the present application, as shown in Figure 9 the ship unloader further comprises a material buffer pool 901, one end of the material buffer pool 901 is in communication with the material guiding channel 801 of the chute main body arranged along the height direction of the tower support 1, and the other end is arranged inclined towards the ground. It can be understood that in the present embodiment, since the chute main body is arranged along the height direction of the tower support 1, the material located in the chute main body has a high falling speed, and therefore the material buffer pool 901 arranged inclined can slow down the speed of the material in the material guiding channel 801, reduce the impact of the material on the subsequent equipment, and improve the continuity of the material conveying.

[0074] According to one embodiment of the present application, the second conveying mechanism is arranged at one end of the material buffer pool 901 away from the chute main body. In this embodiment, the second conveying mechanism comprises a wave baffle belt conveyor 902, a funnel head 903 and a wharf belt conveyor 904. The wave baffle belt conveyor 902 is connected to the chute main body at one end and to the funnel head 903 at the other end, and the material guiding opening of the funnel head 903 is connected to the wharf belt conveyor 904. It should be noted that the position of the wave baffle belt conveyor 902, for example, the inclination angle, can be adjusted according to the positions of the funnel head 903 and the wharf belt conveyor to deliver the material in the material buffer pool 901 to the designated position of the wharf, to ensure the continuity of the material delivery and to avoid material accumulation. In addition, the funnel head 903 can be provided with multiple material guiding openings to match more wharf belt conveyors 904 to improve the material delivery efficiency.

[0075] According to one embodiment of the present application, as shown in Figure 9 The first cross beam 301 comprises a first sub-cross beam 3011 and a second sub-cross beam 3012, the first sub-cross beam 3011 is hinged to the second sub-cross beam 3012, and the second sub-cross beam 3012 is connected to the sleeve frame support 2; the second cross beam 302 is further provided with a second driving mechanism 3021 at one end away from the sleeve frame support 2, and the second driving mechanism 3021 is adapted to drive the first sub-cross beam 3011 to reciprocate in the direction of the sleeve frame support 2. In this embodiment, the second driving mechanism 3021 drives the first sub-cross beam 3011 to reciprocate in the direction of the sleeve frame support 2, so that the inclination angle of the first sub-cross beam 3011 can be adjusted according to different situations, the center of gravity of the whole machine is balanced, and the risk of overturning of the ship unloader during operation is reduced.

[0076] According to one embodiment of the present application, as shown in Figure 9 and Figure 11As shown, a pair of fifth pulley sets 204 are arranged on the upper end surface between the sleeve frame supports 2, a pair of sixth pulley sets 30111 are arranged on the first sub-beam 3011, a pair of seventh pulley sets 3022 are arranged on the two sides of the end of the second beam 302 away from the sleeve frame supports 2 and inclined towards the direction away from the ground, and a third counterweight assembly 3023 is arranged on the second beam 302 and slidably connected with the lower end surface of the second beam 302; one end of the third counterweight assembly 3023 is connected with one of the seventh pulley sets 3022, one of the fifth pulley sets 204 and one of the first sub-beams 3011 through flexible ropes in sequence, and the other end is connected with the other seventh pulley set 3022, the other fifth pulley set 204 and the first sub-beam 3011 through flexible ropes in sequence; the second driving mechanism 3021 is connected with one of the fifth pulley sets 204, one of the first pulley sets 202 and the sixth pulley set 30111 through flexible ropes, and connected with the other sixth pulley set 30111, one of the first pulley sets 202 and the other fifth pulley set 204, and connected back to the second driving mechanism 3021. It should be noted that in this embodiment, the connection point of the third counterweight assembly 3023 on the first sub-beam 3011 through the flexible rope can be one or two, as long as the synchronism of the third counterweight assembly 3023 and the first sub-beam 3011 can be ensured.

[0077] In addition, in one example, as Figure 11 shown, the sixth pulley set 30111 is arranged on the first sub-beam 3011 through the fourth support column 30112, one end of the third counterweight assembly 3023 is connected with one of the seventh pulley sets 3022, one of the fifth pulley sets 204 and one end of the fourth support column 30112 through flexible ropes in sequence, and the other end is connected with the other seventh pulley set 3022, the other fifth pulley set 204 and the other end of the fourth support column 30112 through flexible ropes in sequence.

[0078] It can be understood that when the first cross beam 301 is flat, the cable has a long stroke from the pulling point of the first cross beam 301 to the second cross beam 302, and the cable can pull the third counterweight assembly 3023 to the rear end of the second cross beam 302. Due to the presence of the third counterweight assembly 3023, a backward overturning moment can be generated on the tower support 1, so as to balance the overturning moment of the first cross beam 301 on the tower support 1, improve the stability of the whole machine, reduce the pressure of the roller 201 on the sleeve support 2, and reduce the load on the tower support 1. When the ship unloader needs to enter the non-working state to resist bad weather or avoid the wharf ship, the first cross beam 301 needs to enter the pitch state, at this time the reclaimer trolley 603 overcomes the hinge point of the first cross beam 301 and stops on the parking position on the sleeve support 2, the second driving mechanism 3021 retracts the cable, and the first sub-cross beam 3011 starts to pitch. When the first sub-cross beam 3011 pitches, the stroke of the cable from the pulling point of the first cross beam 301 to the second cross beam 302 becomes shorter, the cable starts to relax, and the third counterweight assembly 3023 will slide to the front end of the second cross beam 302 under the action of its own gravity. At this time, the center of gravity is close to the tower support 1, the force arm of the overturning moment is reduced, and the overall overturning moment is also reduced.

[0079] It should be noted that the fifth pulley set 204, the sixth pulley set 30111 and the seventh pulley set 3022 can each be composed of a plurality of pulleys. The second driving mechanism 3021 can also be one or more winding drums.

[0080] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
