Description

Technical Field

[0001] This invention belongs to the field of power transmission tower construction technology, and more specifically, relates to an adaptive and safe power transmission tower assembly device. Background Technology

[0002] In the field of power transmission tower erection, the work scenarios are often characterized by complex terrain, high working heights, and variable construction environments, placing stringent requirements on the mobility, operational stability, and safety performance of the tower erection equipment. Among these, tracked power units combined with jibs and booms have become the mainstream equipment in power transmission tower erection due to the excellent adaptability of the tracked walking mechanism to complex terrains such as mountains and ravines, and the flexibility to adjust the working range according to hoisting needs. To further enhance structural stability and safety redundancy during operation, and to prevent the boom from swaying or falling due to accidental force imbalance during hoisting, the industry generally installs protective steel cables between the top of the jib and the end of the boom, forming a secondary safety protection through the tension constraint of the steel cables.

[0003] However, after the hoisting operation is completed, the crane boom needs to be retracted towards the pole to reduce the space occupied by the equipment and facilitate subsequent transportation or storage. During this process, the protective steel cable, which was originally taut, will lose its tension constraint as the crane boom is retracted. In addition, the steel cable itself has a certain degree of flexibility, so it will inevitably be in a loose, bent, drooping and swaying state. In this disordered state, the protective steel cable is very likely to get tangled and hooked with the device's cables, connecting bolts and other surrounding components, and may even collide with other structures due to swaying.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] An adaptive safety transmission tower assembly device includes a tracked power body, on which a mast is mounted, and a pair of lifting booms are rotatably mounted on the side wall of the mast. A protective steel cable is connected between the top of the mast and the end of the lifting boom.

[0007] The lifting arm is equipped with a lifting assembly, which is used to lift the workpiece.

[0008] The crane boom is also equipped with a storage component, which is used to limit and store the protective steel cable after the crane boom is retracted.

[0009] The storage assembly includes a positioning frame, which is installed on the side wall of the boom. A pair of positioning seats are installed on the side wall of the positioning frame, and the positioning seats are rotatably connected to the boom.

[0010] A pair of connecting arms are installed on the side wall of the lifting boom. Each connecting arm is equipped with a connecting frame and a plug rod is installed on the connecting frame. The end of the connecting arm is slidably connected to the side wall of the positioning seat. The side wall of the positioning seat is provided with a flipping guide rail and a downward guide rail. The connecting arm is in contact with a guide block in a fixed state, and the guide block is provided with a ramp. The flipping guide rail is used to drive the lifting boom to rotate and retract. The plug rods are guided to move closer to each other through the ramp and are inserted into the outside of the protective steel cable. The plug rods are driven to move down through the downward guide rail, so that the protective steel cable is in a taut state.

[0011] In a preferred embodiment of the present invention, the boom and the lifting arm are both assembled from several pairs of standard sections by bolts, and the positioning frame is installed between two adjacent standard sections.

[0012] In a preferred embodiment of the present invention, a retraction assembly is installed between the lifting boom and the boom. The retraction assembly includes a bracket, and a retraction winch is installed inside the bracket. A cable is installed at the output end of the retraction winch. The cable is sleeved with a guide universal wheel at the end of the lifting boom, and the end of the cable is connected to the side wall of the bracket. The protective steel cable is connected to the side wall of the bracket.

[0013] In a preferred embodiment of the present invention, the lifting assembly includes a lifting winch, which is installed inside the positioning frame. A lifting cable is installed at the output end of the lifting winch. The lifting cable is connected to the positioning frame and the reversing guide wheel provided on the lifting arm, respectively. A hook is installed at the end of the lifting cable.

[0014] In a preferred embodiment of the present invention, a connector is installed on the outer wall of the positioning frame. The connector is L-shaped and has a positioning hole. The bottom of the connector is fitted onto the support rod. The positioning hole is used to connect the connector and the support rod together by bolts.

[0015] In a preferred embodiment of the present invention, an mounting plate is installed on the side wall of the positioning seat, and the mounting plate is connected to the side wall of the positioning frame by bolts. A positioning shaft is installed between the positioning seats, and a fixing seat is also installed on the positioning shaft. The fixing seat is installed on the side wall of the positioning frame. A connecting plate is rotatably installed on the outer side wall of the positioning shaft. The connecting plate is triangular, and the end of the connecting plate is connected to the end of the lifting arm.

[0016] In a preferred embodiment of the present invention, a slide block is movably inserted into the connecting arm, and a sliding groove is provided at the end of the lifting arm. The sliding groove is slidably connected to the slide block, and a guide rod is installed through the sliding groove. The guide rod is movably inserted into the slide block, and a tension spring is sleeved on the outer wall of the guide rod. One end of the tension spring is engaged with the side wall of the sliding groove, and the other end of the tension spring is engaged with the side wall of the slide block. The tension spring is used to drive the connecting arm to fit against the outer wall of the guide block.

[0017] In a preferred embodiment of the present invention, a sliding rod is installed on the side wall of the connecting arm. The sliding rod is slidably mounted on the flipping guide rail. The flipping guide rail is an arc guide rail, and the downward guide rail is an inclined guide rail. The downward guide rail and the flipping guide rail are interconnected. The flipping guide rail includes a section a and a section b. The distance from section a to the downward guide rail is greater than the distance from section b to the downward guide rail. The central angle of section b corresponds to that of the slope.

[0018] In a preferred embodiment of the present invention, a push rod is installed at the end of the connecting arm, a ball is installed at the end of the push rod, the ball is in contact with the side wall of the guide block, and the guide block is installed on the side wall of the positioning shaft.

[0019] In a preferred embodiment of the present invention, the two insert rods located on the same lifting arm have different shapes. One insert rod is cylindrical, and the other is straight, with the outer diameter of the straight rod matching the inner diameter of the cylindrical rod. The present invention has the following advantages compared to the prior art:

[0020] During the slow retraction of the lifting boom towards the boom, the sliding rod in the storage assembly slides precisely along the arc trajectory of the flipping guide rail. Combined with the guiding effect of the ramp on the guide block, this smoothly drives the connecting arms on both sides and the insert rods on the connecting frame to move towards each other. This allows the insert rods to precisely fit onto the outside of the slack, drooping protective steel cable after storage, thus initially limiting the protective steel cable and preventing excessive swaying. Furthermore, the sliding rod continues to slide into the downward guide rail connected to it. The inclined trajectory of the downward guide rail drives the insert rods to move downwards as a whole, creating a continuous and stable downward force on the protective steel cable. This gradually straightens the slack and bent protective steel cable and maintains it in a slightly taut and stable state. This method improves upon the problems of swaying and entanglement of surrounding components caused by the slack and bent protective steel cable after storage, helping to ensure the structural neatness and overall stability of the device in its stored state. It also reduces the risk of collision damage caused by disorderly swaying of the protective steel cable during equipment transportation or idle periods, providing reliable protection for the safe storage and transportation of the equipment after storage.

[0021] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0033] Example 1:

[0034] like Figures 1 to 8 As shown, an adaptive safety transmission tower assembly device includes a tracked power body 1, on which a mast 2 is mounted. A pair of lifting booms 3 are rotatably mounted on the side wall of the mast 2, and a protective steel cable 7 is connected between the top of the mast 2 and the end of the lifting boom 3.

[0035] A lifting assembly is installed on the boom 3, and the lifting assembly is used to lift the workpiece;

[0036] The boom 3 is also equipped with a storage component, which is used to limit and store the protective steel cable 7 after the boom 3 is stored.

[0037] The storage assembly includes a positioning frame 10, which is installed on the side wall of the boom 2. A pair of positioning seats 15 are installed on the side wall of the positioning frame 10, and the positioning seats 15 are rotatably connected to the boom 3.

[0038] A pair of connecting arms 18 are installed on the side wall of the boom 3. Each connecting arm 18 is equipped with a connecting frame 19, and a rod 20 is installed on the connecting frame 19. The end of the connecting arm 18 is slidably connected to the side wall of the positioning seat 15. The side wall of the positioning seat 15 is provided with a flipping guide rail 27 and a downward guide rail 28. The connecting arm 18 is in contact with the guide block 29 in a fixed state, and the guide block 29 is provided with a ramp 30. The flipping guide rail 27 is used to drive the boom 3 to rotate and retract. The ramp 30 guides the rods 20 to approach each other and insert them into the outside of the protective steel cable 7. The downward guide rail 28 drives the rods 20 to move downward, so that the protective steel cable 7 is in a taut state.

[0039] like Figures 1 to 8 As shown, in a specific embodiment, both the boom 2 and the jib 3 are assembled from several pairs of standard sections using bolts, and the positioning frame 10 is installed between two adjacent standard sections. The standard section assembly of the boom 2 and jib 3 allows for flexible adjustment of height and length according to operational needs, adapting to different scales of tower erection operations. Simultaneously, installing the positioning frame 10 between adjacent standard sections enhances the connection stability between the positioning frame 10 and the boom 2, and also facilitates the disassembly, assembly, and maintenance of the positioning frame 10.

[0040] like Figures 1 to 8As shown, a retraction assembly is further installed between the boom 3 and the boom 2. The retraction assembly includes a bracket 4, inside which a retraction winch 5 is installed. A cable 6 is installed at the output end of the retraction winch 5. The cable 6 is connected to the guide caster at the end of the boom 3, and the end of the cable 6 is connected to the side wall of the bracket 4. A protective steel cable 7 is also connected to the side wall of the bracket 4. The bracket 4 ensures the stable installation of the retraction winch 5. With the cooperation of the retraction winch 5 and the cable 6, the extension and retraction of the boom 3 can be precisely controlled. The guide caster ensures the smooth transmission of the cable 6. At the same time, the connection between the protective steel cable 7 and the bracket 4 improves the installation stability of the protective steel cable 7, ensuring that the retraction assembly and the protective steel cable 7 work together to ensure the operational safety of the boom 3.

[0041] like Figures 1 to 8 As shown, the lifting assembly further includes a lifting winch 11, which is installed inside the positioning frame 10. A lifting cable 9 is installed at the output end of the lifting winch 11. The lifting cable 9 is connected to both the positioning frame 10 and the reversing guide wheels 12 on the lifting boom 3. A hook 8 is installed at the end of the lifting cable 9. Installing the lifting winch 11 inside the positioning frame 10 saves space and improves the safety of the lifting winch 11. The reversing guide wheels 12 provide precise guidance for the lifting cable 9, and the hook 8 enables stable lifting of the workpiece, improving the lifting accuracy and stability of the lifting assembly and ensuring efficient tower erection operations.

[0042] Example 2:

[0043] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a connector 13 is installed on the outer wall of the positioning frame 10. The connector 13 is L-shaped and has a positioning hole 14. The bottom of the connector 13 is fitted onto the support rod 2. The positioning hole 14 is used to connect the connector 13 and the support rod 2 through bolts. The L-shaped connector 13 increases the contact area with the support rod 2. Combined with the bolt connection through the positioning hole 14, it can significantly improve the connection stability between the positioning frame 10 and the support rod 2, prevent the positioning frame 10 from shaking during the operation of the device, and ensure the stable operation of the storage component and the lifting component.

[0044] like Figures 1 to 8As shown, in a specific embodiment, a mounting plate is installed on the side wall of the positioning seat 15, and the mounting plate is bolted to the side wall of the positioning frame 10. A positioning shaft 16 is installed between the positioning seats 15, and a fixing seat 26 is also installed on the positioning shaft 16. The fixing seat 26 is installed on the side wall of the positioning frame 10. A connecting plate 17 is rotatably installed on the outer side wall of the positioning shaft 16. The connecting plate 17 is triangular, and its end is connected to the end of the lifting arm 3. The bolted connection of the mounting plate enables a detachable connection between the positioning seat 15 and the positioning frame 10, facilitating maintenance and replacement. The positioning shaft 16, in conjunction with the fixing seat 26, improves the installation stability of the positioning seat 15. The triangular connecting plate 17, with its own structural characteristics, enhances the load-bearing strength of the connection between the lifting arm 3 and the positioning shaft 16, ensuring the structural stability of the lifting arm 3 during rotation.

[0045] like Figures 1 to 8 As shown, a slide block 21 is movably inserted into the connecting arm 18. A groove 22 is provided at the end of the lifting arm 3, and the groove 22 is slidably connected to the slide block 21. A guide rod 23 is installed through the groove 22, and the guide rod 23 is movably inserted into the slide block 21. A tension spring 24 is sleeved on the outer wall of the guide rod 23. One end of the tension spring 24 is engaged with the side wall of the groove 22, and the other end is engaged with the side wall of the slide block 21. The tension spring 24 is used to drive the connecting arm 18 to fit against the outer wall of the guide block 29. The cooperation between the groove 22 and the slide block 21 ensures the smooth sliding of the connecting arm 18. The guide rod 23 provides precise guidance for the sliding trajectory of the slide block 21. The tension spring 24 continuously drives the connecting arm 18 to fit against the guide block 29, ensuring the accuracy of the subsequent insertion rod 20 movement and improving the reliability of the linkage of the storage components.

[0046] Example 3:

[0047] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a slide rod 25 is installed on the side wall of the connecting arm 18. The slide rod 25 is slidably mounted on the flip guide rail 27. The flip guide rail 27 is an arc guide rail, and the downward guide rail 28 is an inclined guide rail. The downward guide rail 28 and the flip guide rail 27 are interconnected. The flip guide rail 27 includes a section guide rail 27a and a section guide rail 27b. The distance from section guide rail 27a to the downward guide rail 28 is greater than the distance from section guide rail 27b to the downward guide rail 28. The central angle of section guide rail 27b corresponds to that of the ramp 30. The sliding cooperation between the slide bar 25, the flip guide rail 27, and the downward guide rail 28 ensures the smooth movement of the connecting arm 18. The arc-shaped flip guide rail 27 is adapted to the rotation trajectory of the lifting arm 3, and the inclined downward guide rail 28 can accurately guide the insertion rod 20 to move downward. The distance design of the a-section guide rail 27a and the b-section guide rail 27b is matched with the central angle of the ramp 30 to ensure that the insertion rod 20 can accurately move towards each other and put on the protective steel cable 7, thus improving the accuracy of the storage component's movement.

[0048] like Figures 1 to 8 As shown, in a specific embodiment, a push rod 31 is installed at the end of the connecting arm 18, and a ball bearing 32 is installed at the end of the push rod 31. The ball bearing 32 fits against the side wall of the guide block 29, which is mounted on the side wall of the positioning shaft 16. The ball bearing 32 at the end of the push rod 31 converts sliding friction into rolling friction, reducing frictional loss between the connecting arm 18 and the guide block 29, extending the service life of the components, and ensuring the smoothness and stability of the sliding of the connecting arm 18 along the guide block 29, thus ensuring the precision and efficiency of the linkage action of the storage component.

[0049] like Figures 1 to 8 As shown, the two insertion rods 20 located on the same lifting arm 3 have different shapes. One insertion rod 20 is cylindrical, and the other is straight. The outer diameter of the straight rod is compatible with the inner diameter of the cylindrical rod. This compatible design of the cylindrical and straight insertion rods 20 enables precise insertion and connection, improves the limiting effect on the protective cable 7, prevents the protective cable 7 from slipping during the limiting process, and ensures the stability of the protective cable 7 after it is stored.

[0050] The implementation principle of the adaptive safe transmission tower device of the present invention is as follows:

[0051] The tracked power unit 1 serves as the core of the device's movement and power, specifically including a tracked walking mechanism, a diesel engine set, a hydraulic drive system, a central control console, and a load-bearing base. The tracked walking mechanism enables the entire device to move flexibly to the designated power transmission tower working position. The diesel engine set is the power output source for the entire device. The hydraulic drive system operates in conjunction with various functional components. The central control console is used for centralized control of the coordinated operation of various components. The load-bearing base is used to securely install the upper structure, such as the boom 2. The boom 2 is assembled from several pairs of standard sections using bolts. The positioning frame 10 is securely installed between two adjacent standard sections of the boom 2 using L-shaped connectors 13 on the outer wall and bolts passing through the positioning holes 14. The positioning seat 15 is bolted to the side wall of the positioning frame 10 via a mounting plate on the side wall. The positioning shaft 16 is mounted between two positioning seats 15 and connected to the side wall of the positioning frame 10 via a fixed seat 26. A triangular connecting plate 17 is rotatably mounted on the outer wall of the positioning shaft 16, with its end connected to the end of the boom 3, thereby enabling the boom 3 to be rotatably installed on the side wall of the boom 2.

[0052] When hoisting operations are required, the hoisting winch 5 of the hoisting assembly is started. The cable 6 at its output end is sleeved with the guide universal wheel at the end of the boom 3 and the end is connected to the side wall of the support 4. The hoisting winch 5 rewinds the cable 6, which allows the boom 3 to rotate outward around the positioning shaft 16 under the action of gravity. Then the hoisting winch 11 is started. The hoisting cable 9 at its output end is reversed and guided by the positioning frame 10 and the reversing guide wheel 12 on the boom 3. The workpiece is hoisted through the hook 8 at the end. During this process, the slide bar 25 on the connecting arm 18 is in the position of section a guide rail 27a of the flipping guide rail 27. The elastic force of the tension spring 24 pushes the slide block 21 to slide in the slide groove 22, thereby driving the top rod 31 and the ball 32 at the end of the connecting arm 18 to always be in contact with the outer wall of the guide block 29, ensuring the stability of the position of the connecting arm 18.

[0053] When the hoisting operation is completed and the boom 3 needs to be retracted, the winch 5 is controlled to rotate in reverse and retract the cable 6. The tension generated by the cable 6 pulls the boom 3, causing it to rotate around the positioning shaft 16 as the center of rotation. This drives the triangular connecting plate 17 to rotate synchronously and retract smoothly towards the boom 2. The protective steel cable 7, which was originally in a straight and taut state due to the tension of the boom 3, loses its tension constraint and immediately becomes relaxed and bent due to its own flexible nature. At this time, the protective steel cable 7 has no external force limit and is very prone to shaking and entanglement with surrounding parts.

[0054] Meanwhile, under the continuous elastic thrust of the tension spring 24, the slide block 21 remains in close contact with the side wall of the slide groove 22, thereby causing the ball bearing 32 on the end rod 31 of the connecting arm 18 to closely contact the outer side wall of the guide block 29. This ensures that the slide rod 25 on the connecting arm 18 slides precisely along the arc trajectory of the flipping guide rail 27 until it slides into the position of the b-section guide rail 27b, and the central angle of the b-section guide rail 27b corresponds exactly to the central angle of the ramp 30 on the guide block 29. The ball bearing 32 rolls along the inclined surface of the ramp 30. At this time, a guiding thrust will be generated on the connecting arm 18, causing the two connecting arms 18 to approach each other along a synchronous trajectory. The plug rod 20 installed on the connecting frame 19 on the connecting arm 18 will also move synchronously towards each other until the straight plug rod 20 whose outer diameter matches the inner diameter of the cylindrical plug rod 20 is precisely inserted into the inner cavity of the cylindrical plug rod 20. The two are then enclosed and fitted on the outside of the protective steel cable 7, completing the initial limiting of the protective steel cable 7 and effectively avoiding the problem of large-scale shaking and entanglement of the protective steel cable 7 due to excessive slack.

[0055] Subsequently, the slide rod 25 smoothly slides from the b-section guide rail 27b of the flipping guide rail 27 into the downward guide rail 28, which is connected to it. The downward guide rail 28 is an inclined guide rail, and its inclined trajectory guides the slide rod 25 to move downward, thereby driving the connecting arm 18 to move downward along the inclined direction. The connecting arm 18 then pulls the insert rod 20 sleeved on the outside of the protective steel cable 7 to move downward simultaneously. During the downward movement, the insert rod 20 forms a continuous and stable downward force on the protective steel cable 7, so that the originally loose and bent protective steel cable 7 is gradually straightened and finally in a slightly taut and stable state. This achieves the adaptive limit storage of the protective steel cable 7 after the crane arm 3 is stored, ensuring the structural neatness and safety of the device in the stored state.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
