Description

Technical Field

[0001] The invention belongs to the technical field of wind resistance of tower power generation equipment, and particularly relates to a steel strand cable guy wire tensioning tooling which is convenient for replacement. Background Art

[0002] The molten salt tower-type solar thermal power generation technology uses salt as the heat absorption and heat storage medium, and utilizes the solar energy collected by a large-scale heliostat field to heat and store the molten salt. Then, according to the dispatching instructions of the power grid, the high-temperature and high-pressure steam generated by the heat exchange between the molten salt and water is used to drive a steam turbine generator set to generate electricity. This technology mainly installs multiple reflecting mirrors around the heat collection device, and reflects and converges the sun's rays to the top of the heat collection device on the tower to heat the molten salt, so as to achieve the purpose of power generation. In this power generation technology, the equipment for solar energy collection is mainly the secondary emission tower module. During the construction and use of the secondary emission tower, a tensioning tooling will be built around the tower body, and together with the steel strand cable guy wire, the overall wind resistance of the tower body can be improved. However, the existing tensioning tooling has the following deficiencies in actual use:

[0003] 1. The overall connection between the existing tensioning tooling and the steel strand cable guy wire is complex. When the tensioning tooling is damaged, it is inconvenient for the staff to replace it, which greatly increases the labor intensity of the staff.

[0004] 2. The existing tensioning tooling cannot adjust the tension of the steel strand cable guy wire according to needs during the construction of the tower body and the change of wind force, resulting in poor overall wind resistance efficiency and low practicability.

[0005] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the Invention

[0006] The purpose of the invention is to provide a steel strand cable guy wire tensioning tooling which is convenient for replacement and can effectively adjust the tension, and solves the problems of inconvenient overall replacement and inconvenient tension adjustment existing in the actual use of the existing steel strand cable guy wire tensioning tooling.

[0007] To solve the above technical problems, the invention is realized through the following technical solutions:

[0008] The invention provides a steel strand cable guy wire tensioning tooling which is convenient for replacement, including a rectangular connection frame, a base, a hydraulic cylinder and a steel wire rope. The hydraulic cylinder is arranged vertically inside the rectangular connection frame, and the base is arranged below the rectangular connection frame. The upper and lower ends of the hydraulic cylinder are respectively fixedly connected with a first convex cover and a second convex cover by bolts.

[0009] Above the first convex cover, there is a gear column meshed with the gear bar on the inner wall of the top surface of the rectangular connection frame. The gear column is connected to the first bevel gear through the first rotating shaft, and the first rotating shaft is rotatably connected to the top surface of the first convex cover. The first bevel gear is meshed with the second bevel gear. The second bevel gear is fixedly sleeved on the second rotating shaft, and the second rotating shaft is rotatably connected to the top surface of the first convex cover. At both ends of the second rotating shaft, internal hexagonal sleeves are symmetrically arranged. The gear bar is arranged parallel to the second rotating shaft, and both ends of the gear bar extend towards the open end of the rectangular connection frame;

[0010] On the side surfaces of the second convex covers on both sides of the gear bar, T-shaped plates are arranged. The T-shaped plates are in clearance fit with the T-shaped grooves with open ends at both ends on the inner part of the top surface of the rectangular connection frame. In the rectangular connection frame above the gear bar, a first through groove parallel to the gear bar is arranged;

[0011] At a position where the bottom area of the rectangular connection frame is not greater than 1 / 2, a rotating block is arranged. Below the remaining area part, a rotating pin is arranged. One end of the rotating pin is fixedly connected to one side surface of the rotating block, and in the connection body of the rotating pin and the rotating block, a second through groove is coaxially arranged with the rotating pin;

[0012] When two rectangular connection frames need to be symmetrically spliced, the two first through grooves are fixed by the same first connecting column and the first nut, and at the same time, the two second through grooves are fixed by the same second connecting column and the second nut.

[0013] Further, in the middle of the top surface of the T-shaped plate, a locking screw pin is in screw fit, and the upper end of the locking screw pin slides through the top plate of the rectangular connection frame and extends above the rectangular connection frame.

[0014] Further, on the top plates of the rectangular connection frames on both sides of the gear bar, strip-shaped wire grooves with one end open are symmetrically arranged. When the two rectangular connection frames are spliced, the open ends of the strip-shaped wire grooves are arranged close to each other.

[0015] Further, at the four corner positions of the outer extension part of the second convex cover, steel wire ropes are fixedly connected. The other ends of the steel wire ropes pass through the outer extension part of the first convex cover movably, and taking the two steel wire ropes on the same side of the gear bar as a group, each group of steel wire ropes is in clearance fit in the same strip-shaped wire groove.

[0016] Further, a clamping plate is slidably sleeved on the steel wire rope. At the four corner positions of the bottom surface of the clamping plate, positioning columns for being in clearance fit with the positioning grooves on the top surface of the rectangular connection frame are arranged.

[0017] Further, an inclined plate is integrally formed on the top surface of the base. The upper end of the inclined plate is used for the clearance fit of the rotating pin. One end of the rotating pin passing through the inclined plate is also fixedly connected with a limiting sleeve by a bolt.

[0018] Further, a trapezoidal platform is arranged on the inner bottom surface of the rectangular connecting frame. An installation groove for the sliding fit of the roller is arranged in the trapezoidal platform, and a wire passing groove communicating with the installation groove is arranged in the middle of the top surface of the trapezoidal platform;

[0019] A traction rope is wound around the roller. A hook is arranged at one end of the traction rope, and the end with the hook passes through the wire passing groove and is hung with the first hanging ring on the bottom surface of the second convex cover; Limiting rings are also arranged on the rollers on both sides of the traction rope;

[0020] Both ends of the roller are rotatably connected to the trapezoidal platform through rolling bearings, and a hexagonal block is arranged on the end surface of the roller far from the opening end of the strip-shaped wire passing groove.

[0021] Further, first through holes are arranged on the rollers outside the two limiting rings. Second through holes are arranged on the trapezoidal platform above the first through holes. The first through hole and the second through hole on the same vertical plane are positioned by a pin.

[0022] Further, a tension detection mechanism is also arranged above the rectangular connecting frame. The tension detection mechanism includes a positioning sleeve, a spring, a connecting block and a tension sensor. The two ends of the spring are respectively hung with the second hanging ring on the side wall of the positioning sleeve and the third hanging ring on the top surface of the connecting block. The bottom surface of the connecting block is connected with the input end of the tension detection mechanism through a pull rope. Insertion plates are arranged on the two symmetrical side surfaces of the tension detection mechanism. The insertion plates are used for sliding and inserting into the U-shaped insertion strips on the top surface of the rectangular connecting frame.

[0023] Further, the number of the positioning sleeves is equal to the number of the steel wire ropes. Each steel wire rope is slidably sleeved with a positioning sleeve, and the positioning sleeve is locked with the steel wire rope by a screw on its side wall. One ends of multiple springs are fitted on the same connecting block.

[0024] The present invention has the following beneficial effects:

[0025] 1. When replacing the rectangular connection frame in the present invention, only the limit sleeve needs to be removed, then the two rectangular connection frames are aligned, and the two rectangular connection frames are connected through the first connecting column and the second connecting column. Then, the staff cooperates a tool with any one of the internal hexagonal sleeves and rotates it. Under this rotation action, the second rotating shaft drives the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear to realize the rotation of the gear column. By moving the gear column on the gear strips where the two rectangular connection frames are aligned, the original rectangular connection frame can be disengaged from its original working position, and the replaced rectangular connection frame can be moved to the original working position, thus realizing the quick and convenient replacement of the whole rectangular connection frame.

[0026] 2. In the present invention, through the detachable installation between the first convex cover and the second convex cover and the hydraulic cylinder, when the hydraulic cylinder needs to be replaced, the staff only needs to first hook the hook on the first hanging ring, and cooperate the tool with the hexagonal block to realize that the roller drives the traction rope to wind to the designated position, and use the pin to realize the positioning of the roller. After that, the staff can replace the hydraulic cylinder by removing the bolts on the first convex cover and the second convex cover. This setting can realize the quick and convenient replacement of the hydraulic cylinder in case of cylinder explosion.

[0027] 3. In the present invention, through the setting of the tension detection mechanism, when the tension change of the spring exceeds the predetermined value or the vibration of the spring exceeds the predetermined value, the pull rope will transmit this information to the tension sensor. At this time, the tension sensor will transmit this information to the PLC controller, and the PLC controller will control the telescopic movement of the hydraulic cylinder to drive the steel wire rope to be adjusted, so as to realize the quick adjustment of the tension of the steel wire rope.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] Please refer to Figures 1-5 As shown in the figure, the present invention is a steel strand cable wind rope tensioning tooling that is convenient for replacement, including a rectangular connection frame 1, a base 2, a hydraulic cylinder 5, and a steel wire rope 7. The hydraulic cylinder 5 is arranged vertically inside the rectangular connection frame 1. At the same time, the base 2 is arranged below the rectangular connection frame 1. The upper and lower ends of the hydraulic cylinder 5 are respectively fixedly connected with a first convex cover 6 and a second convex cover 4 by bolts. This setting facilitates the disassembly and installation between the first convex cover 6 and the second convex cover 4 and the hydraulic cylinder 5. The first convex cover 6 realizes the fixed connection between the hydraulic cylinder 5 and the rectangular connection frame 1, and the second convex cover 4 is used to drive the movement of the steel wire rope 7 under the telescopic action of the hydraulic cylinder 5;

[0047] A rotating block 1013 is arranged at a position where the bottom area of the rectangular connection frame 1 is not greater than 1 / 2, and a rotating pin 101 is arranged below the remaining area part. One end of the rotating pin 101 is fixedly connected to one side surface of the rotating block 1013. This setting can realize the rotation of the rectangular connection frame 1 relative to the inclined plate 201 with the rotating pin 101 as the axis during tension adjustment, and a second through groove 1012 coaxial with the rotating pin 101 is arranged in the connection body of the rotating pin 101 and the rotating block 1013;

[0048] The top surface of the base 2 is integrally formed with an inclined plate 201. The upper end position of the inclined plate 201 is used for the clearance fit of the rotating pin 101. One end of the rotating pin 101 passing through the inclined plate 201 is also fixedly connected with a limit sleeve 1011 by a bolt. The setting of the limit sleeve 1011 facilitates the limitation of one end of the rotating pin 101, realizing the disassembly and assembly of the connection between the rotating pin 101 and the inclined plate 201.

[0049] During the actual use process, the base 2 is fixedly connected to the bottom surface to play a positioning role. At the same time, the electrical components of the device are connected to the PLC controller through transmission wires, so as to realize the automatic control of the PLC controller over each electrical component.

[0050] Please refer to Figure 4 、 7 As shown in and Figure 9, above the first convex cover 6, there is a gear column 601 meshing with the gear rack 106 on the inner wall of the top surface of the rectangular connection frame 1. The gear column 601 is connected to the first bevel gear 6012 through the first rotating shaft 6011, and the first rotating shaft 6011 is rotatably connected to the top surface of the first convex cover 6. The first bevel gear 6012 meshes with the second bevel gear 602. The second bevel gear 602 is fixedly sleeved on the second rotating shaft 6021, and the second rotating shaft 6021 is rotatably connected to the top surface of the first convex cover 6. At both ends of the second rotating shaft 6021, internal hexagonal sleeves 6022 are symmetrically arranged. The internal hexagonal sleeves 6022 are convenient for the cooperation with tools. The gear rack 106 is arranged parallel to the second rotating shaft 6021, and both ends of the gear rack 106 extend towards the open end of the rectangular connection frame 1.

[0051] On the side surfaces of the second convex covers 4 on both sides of the gear rack 106, T-shaped plates 603 are arranged. The T-shaped plates 603 are in clearance fit with the T-shaped grooves 105 with open ends at both ends on the inner part of the top surface of the rectangular connection frame 1. The setting of the T-shaped grooves 105 can play a role in limiting and guiding the movement of the second convex covers 4. In the rectangular connection frame 1 above the gear rack 106, a first through groove 103 parallel to the gear rack 106 is arranged. In the middle of the top surface of the T-shaped plate 603, a locking screw pin 6031 is in screw fit. And the upper end of the locking screw pin 6031 slides through the top plate of the rectangular connection frame 1 and extends above the rectangular connection frame 1. The setting of the locking screw pin 6031 can play a role in positioning and fixing the T-shaped plate 603 during use, avoiding the movement of the T-shaped plate 603 relative to the rectangular connection frame 1 during use.

[0052] When the above settings are in use, the staff cooperate the tool with the hexagon socket 6022. When the tool drives the hexagon socket 6022 to rotate, the second rotating shaft 6021 can drive the second bevel gear 602 to rotate. Due to the meshing setting between the second bevel gear 602 and the first bevel gear 6012, the first rotating shaft 6011 can drive the gear column 601 to rotate. Then, through the meshing setting between the gear column 601 and the gear rack 106, the relative movement of the rectangular connecting frame 1 with respect to the gear column 601 can be realized.

[0053] Please refer to Figures 5-8 As shown in FIGS. 5 and 11, strip-shaped wire grooves 104 with one end open are symmetrically arranged on the top plates of the rectangular connecting frames 1 on both sides of the gear rack 106. The arrangement of the strip-shaped wire grooves 104 facilitates the transition of the steel wire rope 7 from one rectangular connecting frame 1 to another when the two rectangular connecting frames 1 are replaced;

[0054] Four corner positions of the outer extension of the second convex cover 4 are fixedly connected with the steel wire ropes 7. The other ends of the steel wire ropes 7 pass through the outer extension of the first convex cover 6 movably. Taking two steel wire ropes 7 on the same side of the gear rack 106 as a group, each group of steel wire ropes 7 is in clearance fit in the same strip-shaped wire groove 104;

[0055] A clamping plate 9 is slidably sleeved on the steel wire rope 7. Four corner positions of the bottom surface of the clamping plate 9 are provided with positioning posts 901 for clearance fit with the positioning grooves 108 on the top surface of the rectangular connecting frame 1. The setting of the clamping plate 9 can limit the steel wire rope 7 during use, avoiding the sliding of the steel wire rope 7 on the strip-shaped wire groove 104 during use;

[0056] When the above settings are in use, the telescopic movement of the hydraulic cylinder 5 can drive the steel wire rope 7 to adjust the tension through the second convex cover 4. When the rectangular connecting frame 1 needs to be replaced, the staff only needs to disengage the positioning post 901 from the positioning groove 108, and then realize the replacement through the relative movement between the gear column 601 and the gear rack 106. During the replacement process, the steel wire rope 7 can automatically transfer on the strip-shaped wire groove 104.

[0057] Please refer to Figures 13-14 As shown in the figure, when the two rectangular connecting frames 1 need to be symmetrically spliced, the two first through grooves 103 are fixed by the same first connecting column 11 and the first nut 1101 to realize the fixation of the two rectangular connecting frames 1. At the same time, the two second through grooves 1012 are fixed by the same second connecting column 10 and the second nut 1001 to realize the fixation of the two rectangular connecting frames 1. When the two rectangular connecting frames 1 are spliced, the open ends of the strip-shaped wire grooves 104 are arranged close to each other;

[0058] When in use, the above settings can achieve the splicing and fixing of two rectangular connection frames 1 through the first connection post 11 and the second connection post 10. In this case, the gear racks 106 on the two rectangular connection frames 1 are aligned and spliced, facilitating the movement of the gear column 601 on the two gear racks 106.

[0059] Please refer to Figures 6-8 As shown in FIGS. 5 and 12, a trapezoidal platform 102 is provided on the inner bottom surface of the rectangular connection frame 1. An installation groove for the sliding fit of the roller column 3 is provided in the trapezoidal platform 102, and a wire passing groove 1021 communicating with the installation groove is provided in the middle of the top surface of the trapezoidal platform 102. The wire passing groove 1021 facilitates the passing of the traction rope 301.

[0060] A traction rope 301 is wound around the roller column 3. A hook 306 is provided at one end of the traction rope 301, and the end provided with the hook 306 passes through the wire passing groove 1021 and is hooked to the first hanging ring 401 on the bottom surface of the second convex cover 4. Limiting rings 302 are also provided on the roller column 3 on both sides of the traction rope 301. The setting of the limiting rings 302 can limit the traction rope 301 on the roller column 3 from both ends of the traction rope 301.

[0061] Both ends of the roller column 3 are rotatably connected to the trapezoidal platform 102 through rolling bearings, and a hexagonal block 303 is provided on the end surface of the roller column 3 away from the opening end of the strip-shaped wire passing groove 104. The setting of the hexagonal block 303 can achieve the rotation of the roller column 3 in cooperation with a tool.

[0062] First through holes 304 are provided on the roller column 3 on the outer sides of the two limiting rings 302, and second through holes 1022 are provided on the trapezoidal platform 102 above the first through holes 304. The first through holes 304 and the second through holes 1022 on the same vertical plane are positioned by a pin 305. This setting can achieve the positioning and fixing of the roller column 3.

[0063] When in use, in the above settings, when the hydraulic cylinder 5 bursts, the staff only needs to hook the hook 306 on the first hanging ring 401, and then drive the roller column 3 to rotate by cooperating a tool with the hexagonal block 303 to wind the traction rope 301 around the roller column 3. When winding to a specified position, the positioning of the roller column 3 after the specified position is achieved through the cooperation of the pin 305 with the first through hole 304 and the second through hole 1022. In this state, the traction rope 301 can achieve the positioning of the steel wire rope 7. Finally, the staff can replace the hydraulic cylinder 5 by removing the bolts on the first convex cover 6 and the second convex cover 4.

[0064] Please refer to Figure 2 、 6As shown in FIGS. 9 and 10, a tension detection mechanism 8 is further provided above the rectangular connection frame 1. The tension detection mechanism 8 includes a positioning sleeve 801, a spring 802, a connection block 803 and a tension sensor 805. The two ends of the spring 802 are respectively hooked to the second hanging ring 8011 on the side wall of the positioning sleeve 801 and the third hanging ring 8031 on the top surface of the connection block 803. The bottom surface of the connection block 803 is connected to the input end of the tension detection mechanism 8 through a pull rope 804. Plug plates 8051 are provided on both symmetric side surfaces of the tension detection mechanism 8. The plug plates 8051 are used for sliding and fitting into the U-shaped inserts 107 on the top surface of the rectangular connection frame 1. The setting of the U-shaped inserts 107 facilitates the disassembly and installation of the tension detection mechanism 8. When the rectangular connection frame 1 is replaced, it also facilitates the transfer of the tension detection mechanism 8;

[0065] The number of positioning sleeves 801 is equal to the number of steel wire ropes 7. A positioning sleeve 801 is slidably sleeved on each steel wire rope 7, and the positioning sleeve 801 is locked to the steel wire rope 7 through a screw 8012 on its side wall. One ends of multiple springs 802 are fitted on the same connection block 803;

[0066] When in use with the above settings, when the tension of the steel wire rope 7 is low, the spring 802 is in a relaxed state. When the wind force is large, the spring 802 is in a jitter state. When the above situations occur, the spring 802 will transmit the change to the connection block 803, and finally transmit it to the tension sensor 805 through the pull rope 804. The tension sensor 805 transmits this information to the PLC controller so that the hydraulic cylinder 5 can make corresponding adjustments.

[0067] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
