Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and more specifically, to a fixed winch-type gate hoist. Background Technology

[0002] A fixed winch-type gate hoist is a device used in water conservancy and hydropower projects to lift gates.

[0003] In related technologies, fixed winch-type gate hoists mainly include a frame, a drive unit, a drum unit, a wire rope, a movable pulley device, and a hanger. The drive unit and the drum unit are both located at the top of the frame. The wire rope is wound around the drum body of the drum unit and passes through the movable pulley device. The hanger is located at the lower end of the movable pulley device and is used to connect the gate. The drive unit is connected to the drum body and is used to drive the drum body to rotate, thereby driving the gate to perform vertical lifting and lowering movements between the orifice and the dam surface, realizing the opening or closing of the orifice.

[0004] When the gate is lifted onto the dam surface, the movable pulley device moves to its upper limit position. At this time, the movable pulley device is close to the drum device, which causes the wire rope to deflect too much off the drum device. This will cause excessive bending of the wire rope, accelerate fatigue fracture damage of the wire rope, and thus affect the service life of the wire rope and the safe lifting operation of the gate. Utility Model Content

[0005] The problem this invention addresses is how to extend the service life of the wire rope in a fixed winch-type gate hoist.

[0006] To solve the above problems, this utility model provides a fixed winch type gate opener.

[0007] In a first aspect, this utility model provides a fixed winch-type gate opener, including a mounting frame, a drum device, a pulley system, and a wire rope. The mounting frame includes a frame, the drum device includes a drum body and a support, the support and the frame are spaced apart on a support surface along a first direction, the drum body is disposed on the support, and the wire rope is wound around the drum body; wherein, the first direction is perpendicular to the extension direction of the drum body.

[0008] The pulley system includes a movable pulley device and a fixed pulley structure. The fixed pulley structure is located on the top of the frame. The portion of the wire rope that extends out of the drum body is sequentially wound around the fixed pulley structure and the movable pulley device. The movable pulley device is used to connect to the gate.

[0009] Optionally, the mounting frame further includes a frame, the frame and the rack are used to be installed at intervals along the first direction on the support surface, and the support is fixedly disposed on the frame.

[0010] Optionally, the device further includes a drive unit mounted on the frame. The drive unit includes a drive component and a reduction mechanism. The reduction mechanism has a reduction input shaft and a reduction output shaft. The drive component is driven to the reduction input shaft, and the reduction output shaft is connected to the drum body.

[0011] Optionally, the frame includes a crossbeam and multiple legs, the multiple legs being spaced apart on the support surface, the crossbeam being disposed at the top of the legs; and the fixed pulley structure being disposed on the crossbeam.

[0012] Optionally, the pulley system includes two fixed pulley structures, which are spaced apart on the crossbeam along the extension direction of the crossbeam;

[0013] The movable pulley device includes a connecting assembly and a movable pulley structure. The movable pulley structure includes a movable pulley housing, a movable pulley shaft disposed within the movable pulley housing, and two movable pulley portions. The two movable pulley portions are spaced apart from the movable pulley shaft. The connecting assembly is used to connect the movable pulley shaft and the gate.

[0014] The drum body has two drum walls spaced apart along its axial direction. One end of the wire rope is wound around one of the drum walls, and the other end of the wire rope is wound around the fixed pulley structure and the movable pulley portion to connect to the other drum wall. The winding directions of the wire rope on the two drum walls are opposite.

[0015] Optionally, the pulley system further includes a balance wheel structure, which is disposed on the crossbeam and located between the two fixed pulley structures. The fixed pulley structure, the movable pulley section, and the balance wheel structure are connected by the wire rope.

[0016] Optionally, the axial direction of the balance wheel structure is perpendicular to the axial direction of the fixed pulley structure.

[0017] Optionally, the connecting assembly includes multiple connecting plates and a shifting shaft structure. The multiple connecting plates are spaced apart along the extension direction of the movable pulley shaft, and one end of each connecting plate is connected to the movable pulley shaft, while the end of each connecting plate away from the movable pulley shaft is connected to the shifting shaft structure. The shifting shaft structure is used to connect the lifting lug of the gate.

[0018] Optionally, the fixed pulley structure includes a fixed pulley bracket, a fixed pulley shaft, multiple fixed pulley bodies, and an anti-deviation cover. Two fixed pulley brackets are spaced apart on the frame. The two ends of the fixed pulley shaft are respectively connected to the corresponding fixed pulley brackets. Multiple fixed pulley bodies are sleeved on the fixed pulley shaft along the extension direction of the fixed pulley shaft. The anti-deviation cover is disposed on the fixed pulley bracket.

[0019] Optionally, the mounting frame further includes a plurality of anchor bolts, which are respectively provided at the four corners of the frame and pass through the bottom of the frame and the support surface.

[0020] The beneficial effects of this utility model of a fixed winch-type gate opener are:

[0021] The mounting frame and supports can be fixedly installed at intervals along the first direction on the supporting surface, such as the dam surface. The drum body can be rotatably installed on the supports. The fixed pulley structure can be fixedly installed on the top of the frame. The steel wire rope wound on the drum body can pass through the fixed pulley structure and the movable pulley device in sequence to connect the drum body, the fixed pulley structure and the movable pulley device through the steel wire rope. The movable pulley device can be connected to the gate of the water conservancy project.

[0022] When it is necessary to open the orifice of a water conservancy project, the drum body rotates relative to the support, and through the transmission of the wire rope and the moving pulley device, drives the gate to move vertically upward to open the orifice. When the moving pulley device moves to the upper limit position, the distance between the upper limit position of the moving pulley device and the top of the mounting frame is small. Since the height of the frame is positively correlated with the distance between the upper limit position of the moving pulley device and the top of the mounting frame, the design height of the frame can be reduced. Moreover, compared with the prior art where the loads of the drum device, the moving pulley device, and the gate all act on the frame, resulting in a large load on the frame, in this utility model, only the fixed pulley structure is arranged on the frame, while the drum device is arranged on the support surface. A frame with a relatively small load can be selected. In short, by selecting a frame with a relatively small design height and load, the cost of the frame and the fixed winch hoist can be effectively reduced.

[0023] In addition, since the drum device set on the support surface and the fixed pulley structure set on the top of the frame are arranged separately and the two are far apart, the skew angle of the wire rope when it comes out of the drum body is always kept small, which effectively avoids excessive bending of the wire rope, improves the safety and durability of the wire rope, and extends the service life of the wire rope, which is beneficial to the safe lifting operation of the gate.

[0041] To address the problems existing in the aforementioned related technologies, this embodiment provides a fixed winch-type gate hoist.

[0042] like Figure 1As shown in the figure, a fixed winch-type gate hoist provided by this utility model includes a mounting frame 3, a drum device 4, a pulley system 5, and a wire rope 2. The mounting frame 3 includes a frame 32, and the drum device 4 includes a drum body 41 and a support 42. The support 42 and the frame 32 are spaced apart on a support surface along a first direction. The drum body 41 is disposed on the support 42, and the wire rope 2 is wound around the drum body 41. The first direction is perpendicular to the extension direction of the drum body 41.

[0043] The pulley system 5 includes a movable pulley device 51 and a fixed pulley structure 52. The fixed pulley structure 52 is located on the top of the frame 32. The portion of the wire rope 2 that extends out of the drum body 41 is sequentially wound around the fixed pulley structure 52 and the movable pulley device 51. The movable pulley device 51 is used to connect the gate.

[0044] Specifically, the extending direction of the roll body 41 can be parallel to... Figure 1 The X-axis is parallel to the coordinate system, while the first direction can be parallel to... Figure 3 Since the Y-axis is parallel in the coordinate system, the first direction can be perpendicular to the extension direction of the drum body 41.

[0045] The drum body 41 is rotatably mounted on the support 42, so that the drum body 41 can rotate relative to the support 42 or the axis of the drum body 41.

[0046] The fixed pulley structure 52 can be fixedly installed on the top of the frame 32. Part of the wire rope 2 is wound around the drum body 41, and the other part can be wound through the movable pulley device 51 and the fixed pulley structure 52 of the pulley system 5.

[0047] Figure 1 When the movable pulley device 51 is in the upper limit position (the position of the movable pulley device 51 is closest to the top of the frame 32), the gate is lifted to the highest position by the pulley system 5, and the orifice of the water conservancy project is in the open state. Figure 2 When the movable pulley is in its lower limit position (the position of the movable pulley device 51 is farthest from the top of the frame 32), the gate is lowered to its lowest position by the pulley system 5, and the orifice of the water conservancy project is closed.

[0048] In this embodiment, the frame 32 and the support 42 of the mounting frame 3 can be fixedly installed at intervals along the first direction on the supporting surface, such as the dam surface. The drum body 41 can be rotatably installed on the support 42. The fixed pulley structure 52 can be fixedly installed on the top of the frame 32. The steel wire rope 2 wound on the drum body 41 can be wound around the fixed pulley structure 52 and the movable pulley device 51 in sequence, so as to realize the connection of the drum body 41, the fixed pulley structure 52 and the movable pulley device 51 through the steel wire rope 2. The movable pulley device can be connected to the gate of the water conservancy project.

[0049] When it is necessary to open the orifice of the water conservancy project, the drum body 41 rotates relative to the support 42, so as to drive the gate to move vertically upward through the transmission of the wire rope 2 and the moving pulley device 51 to open the orifice. When the moving pulley device 51 moves to the upper limit position, the distance between the upper limit position of the moving pulley device 51 and the top of the mounting frame 3 is small. Since the height of the frame 32 is positively correlated with the distance between the upper limit position of the moving pulley device 51 and the top of the mounting frame 3, the design height of the frame 32 can be reduced. Moreover, compared with the prior art, where the loads of the drum device 4, the moving pulley device 51 and the gate are all applied to the frame 32, resulting in a large load on the frame 32, in this utility model, only the fixed pulley structure 52 is arranged on the frame 32, while the drum device 4 is arranged on the support surface. The frame 32 with a relatively small load can be selected. In short, by selecting the frame 32 with a relatively small design height and load, the cost of the frame 32 and the fixed winch hoist can be effectively reduced.

[0050] Furthermore, because the drum device 4, located on the support surface, and the fixed pulley structure 52, located at the top of the frame 32, are arranged separately and at a considerable distance, the skew angle of the wire rope 2 as it exits the drum body 41 remains small. This effectively prevents excessive bending of the wire rope 2, thereby improving its safety and durability, and extending its service life. This is beneficial for the safe lifting operation of the gate. The skew angle refers to the angle between the wire rope 2 exiting the drum body 41 and the vertical plane, which can be perpendicular to the vertical plane. Figure 3 The planes formed by the X-axis and Z-axis in the coordinate system are parallel.

[0051] The water conservancy project may be a hydropower station or a dam, without specific limitations.

[0052] Optionally, combined Figure 1 and Figure 2 As shown, the mounting frame 3 also includes a frame 31, the frame 31 and the rack 32 are used to be installed at intervals along the first direction on the support surface, and the support 42 is fixedly disposed on the frame 31.

[0053] Specifically, the support 42 of the winding device 4 can be directly installed on the support surface; or, the support 42 of the winding device 4 can be installed on the support surface through a frame, and the frame 31 can serve as the mounting base of the winding device 4. The frame 31 is fixedly installed on the support surface. For example, the winding device 4 includes a winding body 41 and two supports 42. The two supports 42 are spaced apart on the frame 31, and the two ends of the winding body 41 are respectively connected to the corresponding supports 42.

[0054] In this optional embodiment, by arranging the fixed pulley structure 52 on the frame 32 and the drum device 4 on the support surface such as the dam surface via the frame 31, not only is the load on the frame 32 relatively reduced, in other words, the frame 31 with a smaller load can be selected, reducing the cost of the frame 32, but also, since the drum device 4 is set on the frame 31, it is convenient to install, maintain and repair the drum device 4.

[0055] Furthermore, when lifting the gate, the tension of the wire rope 2 on the drum device is upward, which can offset part of the weight of the drum device 4, reduce the load on the drum device 4 and the frame 31, and reduce the overall equipment cost.

[0056] Optionally, combined Figure 3 As shown, the fixed winch-type gate hoist also includes a drive device 6 mounted on the frame 31. The drive device 6 includes a drive component 61 and a reduction mechanism 62. The reduction mechanism 62 has a reduction input shaft and a reduction output shaft. The drive component 61 is drivenly connected to the reduction input shaft, and the reduction output shaft is connected to the drum body 41.

[0057] Specifically, both the drive unit 61 and the reduction mechanism 62 are mounted on the frame 31, so that the frame 31 supports the drive unit 61 and the reduction mechanism 62. The drive unit 61 may be a rotary motor; the reduction mechanism 62 may be a reduction gearbox structure.

[0058] In this optional embodiment, the reduction input shaft and reduction output shaft of the reduction mechanism 62 are respectively connected to the driving device 61 and the drum body 41, so as to transmit the rotational force of the motor shaft of the driving device 61 to the drum body 41 through the reduction mechanism 62, so as to drive the drum body 41 to rotate.

[0059] In addition, since the drum device 4, the drive unit 61 and the deceleration mechanism 62 are all mounted on a support surface, such as a dam surface, via the frame 31, it is convenient to install, maintain and repair the drum device 4, the drive unit 61 and the deceleration mechanism 62.

[0060] Optionally, combined Figure 4 As shown, the frame 32 includes a crossbeam 321 and a plurality of support legs 322, the plurality of support legs 322 being spaced apart on the support surface, the crossbeam 321 being disposed at the top of the support legs 322; the fixed pulley structure 52 being disposed on the crossbeam 321.

[0061] Specifically, multiple support legs 322 are fixedly installed on the support surface, and a crossbeam 321 is set on the upper part of the support legs 322. The top of the support legs 322 is fixedly connected to the crossbeam 321, thereby forming a frame 32 with a structure similar to a gantry.

[0062] In this optional embodiment, the fixed pulley structure 52 can be fixedly installed on the crossbeam 321, while the drum device 4 is installed on the frame 31, so that the fixed pulley structure 52 and the drum device 4 adopt a separate design, which ensures that the two always maintain a large distance, and can ensure that the wire rope 2 wound from the drum body 41 always maintains a small deflection angle, which is beneficial to the safety and durability of the wire rope 2.

[0063] Optionally, combined Figures 3 to 6 As shown, the pulley system 5 includes two fixed pulley structures 52, which are spaced apart on the crossbeam 321 along the extension direction of the crossbeam 321.

[0064] The movable pulley device 51 includes a connecting assembly 514 and a movable pulley structure. The movable pulley structure includes a movable pulley housing 511, a movable pulley shaft 512 disposed within the movable pulley housing 511, and two movable pulley portions 513. The two movable pulley portions 513 are spaced apart from the movable pulley shaft 512. The connecting assembly 514 is used to connect the movable pulley shaft 512 and the gate.

[0065] The drum body 41 has two drum walls 411 spaced apart along its axial direction. One end of the wire rope 2 is wound around one of the drum walls 411, and the other end of the wire rope 2 is wound around the fixed pulley structure 52 and the movable pulley part 513 to connect to the other drum wall 411. The winding directions of the wire rope 2 on the two drum walls 411 are opposite.

[0066] Specifically, in combination Figure 3 and Figure 4 As shown, the two fixed pulley structures 52 of the pulley system 5 are installed at intervals on the upper part of the crossbeam 321 along the extension direction of the crossbeam 321.

[0067] Combination Figure 6 As shown, the extension direction of the movable pulley shaft 512 is parallel to the extension direction of the crossbeam 321, and both ends of the movable pulley shaft 512 pass through the end faces of the movable pulley housing 511. Two movable pulley parts 513 are spaced apart and sleeved on the movable pulley shaft 512. The movable pulley housing 511 can adopt a multi-segment housing structure to improve the ease of disassembly and assembly of the various components in the movable pulley structure and the ease of connection with the connecting assembly 514. The connecting assembly 514 can be connected and fixed to the movable pulley shaft 512 by sleeve.

[0068] The drum body 41 may have two drum walls 411, which can be understood as the part on the drum body 41 where the wire rope 2 is wound, and at least one wire rope 2 can be wound on the drum body 41.

[0069] The wire rope 2 is wound in opposite directions on the two drum walls 411. For example, a portion of the wire rope 2 can be wound clockwise on one drum wall 411, while the other portion can be wound counterclockwise on the other drum wall 411. For example, when the drive device 6 drives the drum body 41 to rotate clockwise relative to the support 42, both drum walls 411 perform a rope winding action, at which time the gate rises. When the drive device 6 drives the drum body 41 to rotate counterclockwise relative to the support 42, both drum walls 411 perform a rope unwinding action, at which time the gate descends.

[0070] In this configuration, a portion of the wire rope 2 is wound around one drum wall 411 of the drum body 41. The part of the wire rope 2 that exits the drum wall 411 passes through different fixed pulley structures 52 and movable pulley parts 513 respectively, and then wound around another drum wall 411. Therefore, the two fixed pulley structures 52, the two movable pulley parts 513 and the two drum walls 411 of the drum body 41 can be connected by the wire rope 2, so that the tension of the wire rope 2 on the gate can be distributed by the two fixed pulley structures 52, reducing the risk of failure of a single fixed pulley structure 52 and improving the stability of the gate lifting.

[0071] Optionally, combined Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, the pulley system 5 also includes a balance wheel structure 53, which is disposed on the crossbeam 321 and located between the two fixed pulley structures 52. The fixed pulley structure 52, the movable pulley part 513 and the balance wheel structure 53 are connected by the steel wire rope 2.

[0072] Specifically, the balance wheel structure 53 can be set on the crossbeam 321, and the balance wheel structure 53 is located between the two fixed pulley structures 52.

[0073] The balance wheel structure 53 can be fixed to the crossbeam 321 by means of bolt fasteners.

[0074] In this optional embodiment, a balance wheel structure 53 located between the two fixed pulley structures 52 can be used to ensure that the length and tension of the steel wire ropes 2 on both sides are kept consistent, thereby achieving a smooth lifting and lowering process of the gate.

[0075] Optionally, combined Figure 7 As shown, the axial direction of the balance wheel structure 53 is perpendicular to the axial direction of the fixed pulley structure 52.

[0076] Specifically, the axial direction of the balance wheel structure 53 can be adopted as follows: Figure 7 The letter 'e' in the text indicates that it can be used with... Figure 7The Y-axis of the coordinate system is parallel; the axial direction of the fixed pulley structure 52 can be adopted. Figure 7 The letter 'd' in the text indicates that it can be used with... Figure 7 The X-axis of the coordinate system is parallel.

[0077] In this optional embodiment, since the axial direction of the balance wheel structure 53 is perpendicular to the axial direction of the fixed pulley structure 52, the direction of the wire rope 2 when it passes through the balance wheel structure 53 is perpendicular to the direction when it passes through the fixed pulley structure 52, which can improve the stability of the gate lifting operation.

[0078] See Figure 9 As shown, after the wire rope 2 is wound out of the drum device 4, it first winds through the fixed pulley structure 51, then through the movable pulley device 52, and after winding through several fixed pulley bodies and several movable pulley bodies in sequence, it finally winds through the balance wheel structure 53.

[0079] Optionally, combined Figure 5 and Figure 6 As shown, the connecting assembly 514 includes a plurality of connecting plates 5141 and a shifting shaft structure. The plurality of connecting plates 5141 are spaced apart along the extending direction of the movable pulley shaft 512, and one end of each connecting plate 5141 is connected to the movable pulley shaft 512, and the end of each connecting plate 5141 away from the movable pulley shaft 512 is connected to the shifting shaft structure. The shifting shaft structure is used to connect the lifting lug 7 of the gate.

[0080] Specifically, the extension direction of the movable pulley shaft 512 can be parallel to... Figure 6 In the coordinate system, the X-axis is parallel, and each connecting plate 11 can be along... Figure 6 The X-axis is arranged at intervals in the coordinate system. Each connecting plate 11 extends vertically. The top of each connecting plate 11 is fitted onto the movable pulley shaft 512, and the bottom of each connecting plate 11 is fitted onto the shifting shaft structure.

[0081] The connection between the shifting shaft structure and the gate can be achieved in the following ways, combined with... Figure 6 , Figure 10 and Figure 11As shown, for example, the shifting shaft structure includes a handwheel 5142, a screw 5143, a sleeve 5144, a lifting shaft 5145, a lifting plate 5146, and a counterweight 5147. The lifting shaft 5145 passes through the ends of the two connecting plates 5141 away from the movable pulley shaft 512. The two lifting plates 5146 can be sleeved on the lifting shaft 5145 and are located between the two connecting plates 5141. The two lifting lugs 7 of the gate are sleeved on the lifting shaft 5145 and are located between the two lifting plates 5146. One axial end of the lifting shaft 5145 is provided with a first mounting groove. The end of the screw 5143 is engaged in the first mounting groove, and the end of the screw 5143 can rotate relative to the lifting shaft 5145 in the first mounting groove to realize the movement of the screw 5143 and the lifting shaft 5145. The sleeve 5144 is fitted around the lifting shaft 5145, and its axial end can be fixedly connected to the connecting plate 5141 via a flange. The other axial end of the screw 5143 passes through the sleeve 5144 and is connected to the handwheel 5142. The end of the sleeve 5144 away from the lifting shaft 5145 has a threaded hole, and the screw 5143 is threadedly connected to the threaded hole of the sleeve 5144. The counterweight 5147 can be a cylindrical structure, with a mounting groove at its axial end. The end of the lifting shaft 5145 away from the sleeve 5144 is embedded in the mounting groove of the counterweight 5147. The axial end of the counterweight 5147 connected to the lifting shaft 5145 can be fixedly connected to the connecting plate 5141 via fasteners. The two lifting plates 5146 serve as a protective space between the gate's lifting lugs 7 and the connecting plate 5141.

[0082] The connection between the gate's lifting lug 7 and the lifting shaft 5145 of the connecting assembly 514 can be achieved in the following manner: for example, by rotating the handwheel 5142 in a first rotational direction (e.g., clockwise) to drive the screw 5143 to rotate. One end of the screw 5143 is threadedly connected to the sleeve 5144, and the other end of the screw 5143 is movably connected to the lifting shaft 5145. This allows the sleeve 5144 to convert the rotational motion of the screw 5143 into the horizontal linear movement of the lifting shaft 5145. During the rotation of the screw 5143, the lifting shaft 5145 can move linearly within the sleeve 5144, allowing one end of the lifting shaft 5145 to disengage from a connecting plate 51. 41. The two lifting lugs 7 of the gate are fitted onto the outside of the lifting shaft 5145, and two lifting plates 5146 are fitted onto the lifting shaft 5145. Then, by rotating the handwheel 5142 in the second rotation direction (e.g., counterclockwise), the screw 5143 is rotated, which causes the lifting shaft 5145 to gradually extend out of the sleeve 5144 until the lifting shaft 5145 passes through the connecting plate 5141 again. At this time, the components fitted onto the lifting shaft 5145 from the vertical center line of the lifting shaft 5145 to both ends are the lifting lugs 7, the lifting plates 5146, and the connecting plate 5141 of the gate, respectively, thereby realizing the connection operation between the lifting lugs 7 of the gate and the lifting shaft 5145 in the connecting assembly 514.

[0083] Figure 6In the middle, there are two connecting plates 11.

[0084] In this optional embodiment, since multiple connecting plates 5141 are spaced apart along the extension direction of the movable pulley shaft 512, and the top and bottom ends of each connecting plate 5141 are respectively connected to the movable pulley shaft 512 and the lifting shaft 5145 of the shifting shaft structure, the connection stability of the shifting shaft structure to the movable pulley shaft 512 in the movable pulley structure through the connecting plates 5141 can be improved by increasing the number of connection points between the shifting shaft structure and the movable pulley shaft 512, thereby improving the lifting stability of the gate.

[0085] Optionally, combined Figure 8 As shown, the fixed pulley structure 52 includes a fixed pulley bracket 521, a fixed pulley shaft 522, multiple fixed pulley bodies 523, and an anti-deviation cover 524. Two fixed pulley brackets 521 are spaced apart on the frame 32. The two ends of the fixed pulley shaft 522 are respectively connected to the corresponding fixed pulley bracket 521. Multiple fixed pulley bodies 523 are sleeved on the fixed pulley shaft 522 along the extension direction of the fixed pulley shaft 522. The anti-deviation cover 524 is disposed on the fixed pulley bracket 521.

[0086] Specifically, the two ends of the fixed pulley shaft 522 are respectively connected to the corresponding fixed pulley brackets 521, and multiple fixed pulley bodies 523 can be arranged and sleeved on the fixed pulley shaft 522 along the extension direction of the fixed pulley shaft 522. The anti-deviation cover 524 can be fixed to the fixed pulley bracket 521 by bolt fasteners or welding.

[0087] The anti-deviation shield 524 can adopt an arc-shaped shield structure.

[0088] In this optional embodiment, multiple fixed pulley bodies 523 can be mounted on two fixed pulley supports 521 via fixed pulley shafts 522, and the wire rope 2 can be wound around the multiple fixed pulley bodies 523. The anti-deviation cover 524 is provided on the fixed pulley support 521 to effectively prevent the wire rope 2 from detaching from the corresponding fixed pulley body 523, thereby ensuring the smooth transmission of the wire rope 2 on the fixed pulley body 523.

[0089] In addition, each movable pulley section 513 may include multiple movable pulley bodies, each fixed pulley structure 52 may include multiple fixed pulley bodies 523, and each balance wheel structure 53 may have at least one balance pulley.

[0090] Optionally, combined Figure 1 As shown, the mounting frame 3 also includes a plurality of anchor bolt fasteners 33, which are respectively provided at the four corners of the frame 31. The anchor bolt fasteners 33 pass through the bottom of the frame 31 and the support surface.

[0091] Specifically, the anchor fastener 33 may include the anchor body and the nut; the frame 31 may be fixedly installed on the support surface in the following manner: part of the anchor body may be pre-embedded in the support surface, such as the dam surface; multiple bolt holes are provided at the four corners of the frame 31; the frame 31 is placed on the support surface, and the anchor body passes through the bolt holes of the frame 31; the nut is put on the anchor body and tightened, so as to fix the frame 31 on the support surface.

[0092] In this optional embodiment, since the four corners of the frame 31 are connected to the support surface by anchor bolts 33, multiple anchor bolts 33 can be fixed from the four corners of the frame 31 to improve the stability of the frame 31 installed on the support surface.

[0093] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
