DETAILED DESCRIPTION

[0024] In order to make the purpose, method scheme and advantages of the embodiments of the utility model more clear, the method scheme in the embodiments of the utility model is clearly and completely described, and obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0025] Embodiment 1: as Figures 1-3As shown, a hydrological trolley shore-side traction system includes: a trolley 1, a first pulley 2, a second pulley 3, a first rope 4, and a movable pulley 5; the first pulley 2 is connected to the trolley 1; the second pulley 3 is connected to the trolley 1; the first rope 4 is wound around the first pulley 2 and the second pulley 3; the movable pulley 5 is located below the first pulley 2 and / or the second pulley 3, and the first rope 4 between the first pulley 2 and the second pulley 3 is wound around the movable pulley 5; the movable pulley 5 is used to connect a lead weight 6.

[0026] In specific implementation, this embodiment mainly improves the traction system of the lead weight 6. The movement of the trolley 1 can be self-driven or traction-driven. A device for driving the release and retraction of the first rope 4, such as a winch, can be located on the shore. One end of the first rope 4 is connected to the winch. The other end of the first rope 4 is fixedly connected, either to the trolley 1 or to the tower 20 on the shore. The first pulley 2 and the second pulley 3 can be... Figure 2 As shown, it is located below the traveling crane 1. The movable pulley 5 can be located at... Figure 2 Inside the inverted triangular shell below.

[0027] In this embodiment, the first pulley 2 and the second pulley 3 are mounted on the traveling crane 1, so that when the traveling crane 1 moves, it can drive the first pulley 2 and the second pulley 3 to move, and then drive the lead weight 6 to move through the movable pulley 5. After the first rope 4 is arranged according to the winding relationship in this embodiment, during the movement of the traveling crane 1, one side of the vertical first rope 4 on both sides of the movable pulley 5 is lowered and the other side is raised, so that the total length of the vertical first rope 4 on both sides of the movable pulley 5 remains unchanged, and thus the height of the lead weight 6 remains unchanged. For example, Figure 2 As shown, when the crane 1 moves to the right, the first rope 4 on the left is raised, and the first rope 4 on the right is lowered. When it is necessary to adjust the height of the lead weight 6, the total length of the released first rope 4 can be adjusted by winding and releasing the winch. When the connection position of the end of the first rope 4 away from the winch is fixed, the change in the total length of the first rope 4 will cause the vertical first rope 4 on both sides of the movable pulley 5 to change, thereby changing the height of the lead weight 6. Under the action of the gravity of the lead weight 6, the movable pulley 5 always keeps the first rope 4 in a taut state.

[0028] Example 2: To maintain the relative position of the lead weight 6 to the direction of the water flow, improvements were made based on Example 1, such as... Figure 2 As shown, in this embodiment, the plane containing the first rope 4 on the side of the first pulley 2 and the first rope 4 on the side of the second pulley 3 is perpendicular to the movement path of the traveling vehicle 1; the radial direction of the movable pulley 5 is perpendicular to the radial direction of the first pulley 2 or the second pulley 3.

[0029] In the specific implementation process, such as Figure 2As shown, the height of the first pulley 2 and the second pulley 3 can be consistent, the side of the first pulley 2 refers to the right side of the first pulley 2, and the side of the second pulley 3 refers to the left side of the second pulley 3. The first pulley 2 and the second pulley 3 are arranged in a staggered manner in the width direction of the winch 1, and the staggered distance can be set according to the diameter of the movable pulley 5. The radial direction of the movable pulley 5 or the second pulley 3 refers to the horizontal diameter direction of the pulley. From the perspective of the movable pulley 5, the first pulley 2 is located on the left side of the movable pulley 5, and the second pulley 3 is located on the right side of the movable pulley 5. Figure 2 As can be seen, the movable pulley 5 is perpendicular to the first pulley 2, which can ensure that the relative relationship between the lead fish 6 and the water flow direction meets the test requirements.

[0030] In order to better realize the limiting of the first rope 4 and ensure the straightness of the first rope 4, the embodiment 1 is improved as shown in the embodiment 3. Figure 2 As shown, in this embodiment, the traction system further comprises a mounting frame 7, a main limiting wheel 8 and a secondary limiting wheel 9; the mounting frame 7 is connected with the winch 1; the main limiting wheel 8 is installed on the mounting frame 7; in the longitudinal direction, the main limiting wheel 8 is located between the first pulley 2 and the movable pulley 5; the secondary limiting wheel 9 is at least two, and the two secondary limiting wheels 9 are located on both sides of the main limiting wheel 8 and are installed on the mounting frame 7; the first rope 4 between the first pulley 2 and / or the second pulley 3 and the movable pulley 5 is located between the secondary limiting wheel 9 and the main limiting wheel 8.

[0031] In the specific implementation process, the mounting frame 7 can be arranged at the bottom of the winch 1. The circumferential direction of the main limiting wheel 8 can be provided with an annular anti-falling groove, and the first rope 4 is located in the anti-falling groove. The circumferential direction of the secondary limiting wheel 9 can adopt a smooth arc surface, and the first rope 4 is limited in the anti-falling groove by the secondary limiting wheel 9. The movement of the first rope 4 in the horizontal four directions will be limited by the first pulley 2, the second pulley 3, the main limiting wheel 8 and the secondary limiting wheel 9, so as to avoid the first rope 4 from being separated from the first pulley 2 or the second pulley 3 or the main limiting wheel 8 when swinging. In addition, it can also avoid the winding phenomenon of the first rope 4.

[0032] The embodiment 4 provides a structure and arrangement of the mounting frame 7, as shown in the embodiment 4. Figure 2 As shown, the mounting frame 7 comprises a longitudinal mounting plate 71 and a transverse mounting plate 72, the longitudinal mounting plate 71 is at least two, the two longitudinal mounting plates 71 are connected with the winch 1, and the main limiting wheel 8 is installed between the two longitudinal mounting plates 71 through a first rotating shaft; the transverse mounting plate 72 is at least two, and the two transverse mounting plates 72 are connected with one of the longitudinal mounting plates 71 respectively, and the two ends of the transverse mounting plate 72 are arranged on both sides of the longitudinal mounting plate 71 respectively; the secondary limiting wheel 9 is installed between the two transverse mounting plates 72 through a second rotating shaft.

[0033] In the implementation, the direction of the transverse mounting plate 72 can be perpendicular to the length direction of the longitudinal mounting plate 71, and the distance between the two ends of the transverse mounting plate 72 and the longitudinal mounting plate 71 can be equal. The longitudinal mounting plate 71, the first pulley 2 and the second pulley 3 can be integrally mounted on the horizontal plate, and then connected with the travelling crane 1 through the horizontal plate. Figure 2

[0034] In order to reduce the difficulty of the layout of the traction system, the embodiment 1-4 is improved, as shown in the embodiment 5, the traction system further comprises a lifting winch 10, a second rope 11, a counterweight 12, a third pulley 13, a fourth pulley 14 and a fifth pulley 15; one end of the second rope 11 is connected with the lifting winch 10; the third pulley 13 is arranged below the counterweight 12, and the fourth pulley 14 is arranged above the counterweight 12; the first rope 4 is arranged around the fourth pulley 14; the fifth pulley 15 is located below the third pulley 13, and the other end of the second rope 11 is sequentially arranged around the fifth pulley 15 and the third pulley 13, and the other end of the second rope 11 is fixedly connected. Figure 5

[0035] In the implementation, the traction system for moving the travelling crane 1 and the traction system for lifting the lead fish 6 can be independent of each other or can be associated with each other.

[0036] For example, when the two traction systems are independent of each other, the travelling crane 1 can be moved through the traction system by referring to the embodiments shown in Figs. 1-4, and the lead fish 6 can be lifted through the traction system by referring to the embodiments shown in Figs. 5-8. Figure 1 Figures 3-4 For example, when the two traction systems are independent of each other, the travelling crane 1 can be moved through the traction system by referring to the embodiments shown in Figs. 1-4, and the lead fish 6 can be lifted through the traction system by referring to the embodiments shown in Figs. 5-8.

[0037] For example, when the two traction systems are independent of each other, the travelling crane 1 can be moved through the traction system by referring to the embodiments shown in Figs. 1-4, and the lead fish 6 can be lifted through the traction system by referring to the embodiments shown in Figs. 5-8. Figure 5 ​​​As shown, one end of the second rope 11 is connected with the lifting winch 10, and the other end of the second rope 11 can be connected with the ground or the tower 20. When the position of the counterweight 12 is unchanged, the first rope 4 drives the trolley 1 to move, and since the total length of the first rope 4 is unchanged, the height of the lead fish 6 is unchanged. When it is necessary to change the height of the lead fish 6, the second rope 11 is moved by the lifting winch 10, thereby changing the height of the counterweight 12. Since the total length of the first rope 4 is unchanged, the height of the lead fish 6 is changed. At this time, the lifting of the lead fish 6 is the result of the cooperation of the first rope 4 and the second rope 11. One end of the first rope 4 can be connected with the outer wall of the trolley 1, and the other end of the first rope 4 can be connected with the inner wall of the trolley 1 after passing through the movable pulley 5 and the first pulley 2. As can be seen from the foregoing, the rope directly connected with the lead fish 6 is the first rope 4, and the rope driving the trolley 1 to move is also the first rope 4. However, as Figure 5 As shown, the second rope 11 can be arranged on the shore, that is, the number of ropes arranged across the water flow is reduced, and the arrangement operation is simpler.

[0038] The arrangement of the counterweight 12 not only provides stability for the lifting of the lead fish 6, but also reduces the pulling force applied by the lifting winch 10 and reduces the load of the motor. The circulating cable track formed by the first rope 4 is taut by the weight of the lead fish 6. The first rope 4 is wound around two groove wheels of the circulating winch, and the forward and backward movement of the trolley 1 is realized by the forward and reverse rotation of the winch groove wheels. The mutual friction between the circulating winch and the first rope 4 can be less than the weight of the lead fish 6. When the trolley 1 needs to move towards the lifting winch 10, since the weight of the lead fish 6 is greater than the circulating friction of the steel wire rope, the first rope 4 suspending the lead fish 6 can be regarded as being fixed on the trolley 1, thereby realizing the movement.

[0039] In order to realize the horizontal movement of the trolley 1, the embodiment 6 is improved on the basis of the embodiment 5, as shown in the figure. Figure 3 Or Figure 5 As shown, in this embodiment, the traction system further comprises a first steering wheel 16, a circulating winch 17 and a second steering wheel 18. One end of the first rope 4 is sequentially wound around the fourth pulley 14 and the first steering wheel 16 after extending to the shore, and the first steering wheel 16 is located above the fourth pulley 14. The other end of the first rope 4 is connected with the trolley 1. After being wound around the first steering wheel 16, one end of the first rope 4 continues to extend to be drivingly connected with the circulating winch 17. The second steering wheel 18 is separately arranged with the first steering wheel 16 at both ends of the moving path of the trolley 1. One end of the first rope 4 is wound around the second steering wheel 18 and connected with the trolley 1.

[0040] In the specific implementation process, the first rope 4 is wound around the first steering wheel 16 and the second steering wheel 18, and the first rope 4 is connected with the trolley 1. Figure 5The first rope 4 is wound on the first pulley 2, the fixed pulley, the second pulley 3, the fourth pulley 14, the first reversing pulley 16, the loop winch 17 and the second reversing pulley 18 in sequence in the counterclockwise winding mode. After passing through the first reversing pulley 16, the first rope 4 extends to the left. After passing through the second reversing pulley 18, the first rope 4 extends to the right until it is connected with the crab 1. The first rope 4 above the water flow is as straight as possible and remains horizontal.

[0041] In order to ensure the horizontal degree of the extension direction of the first rope 4 above the water flow as much as possible, the embodiment 6 is improved as shown in the embodiment 7. Figure 5 As shown in the embodiment 7, the traction system further comprises a guide pulley 19, which is located above the fourth pulley 14. During the extension of the first rope 4 from the sinker 6 to the shore, the first rope 4 is wound on the guide pulley 19, the fourth pulley 14 and the first reversing pulley 16 in sequence.

[0042] In the specific implementation process, if the guide pulley 19 does not exist, the first rope 4 between the fourth pulley 14 and the crab 1 is inclined, and the inclination degree changes with the change of the height of the weight block 12. Therefore, the guide pulley 19 is arranged in the embodiment. The guide pulley 19 can be arranged on the tower 20 on the shore, and the height of the guide pulley 19 can be consistent with the height of the second pulley 3.

[0043] In order to increase the lifting stroke of the sinker 6 and save the space in the height direction of the tower 20, and effectively cover the lifting height of the sinker 6 in the river, the embodiment 7 is improved as shown in the embodiment 8. Figure 5 As shown in the embodiment 8, the fourth pulley 14 and the guide pulley 19 are multiple, and the multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged horizontally along the extension direction of the first rope 4. The multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged staggered in the horizontal direction.

[0044] As shown in the embodiment 8, the fourth pulley 14 and the guide pulley 19 are multiple, and the multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged horizontally along the extension direction of the first rope 4. The multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged staggered in the horizontal direction. Figure 5 As shown in the embodiment 8, the fourth pulley 14 and the guide pulley 19 are multiple, and the multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged horizontally along the extension direction of the first rope 4. The multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged staggered in the horizontal direction.

[0045] As shown in the embodiment 8, the fourth pulley 14 and the guide pulley 19 are multiple, and the multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged horizontally along the extension direction of the first rope 4. The multiple fourth pulleys 14 and the multiple guide pulleys 19 are arranged staggered in the horizontal direction.

[0046] In the implementation process, the track 21 can adopt the form of main cable or the form of rigid guide rail. The lifting winch 10, the circulating winch 17 and the counterweight 12 can be arranged on the same tower 20 as shown. Figure 5

[0047] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
