Description

Technical Field

[0001] This application relates to the field of power pole transfer technology, and more specifically, to an integrated transfer and protection device for annular concrete power poles. Background Technology

[0002] Ring-shaped concrete poles are widely used support components in power transmission and distribution lines. They are centrifugally cast and are hollow conical poles, thicker at one end and thinner at the other. They are heavy and long, and need to be transported from the stacking point to the pole pit at the construction site. Currently, short-distance transportation of poles usually uses flatbed trailers or simple two-wheeled transport frames. The poles are laid flat on the frame and simply tied with ropes or wires before being dragged or pushed.

[0003] However, existing pole transport equipment has the following shortcomings in practical use: First, the poles are simply tied with ropes, lacking a circumferential clamping structure adapted to the outer wall of the pole. When encountering bumpy roads or sloping terrain during transport, the poles are prone to rolling, shifting, or even falling off the frame, causing damage or safety accidents. Second, the thick end of the ring-shaped concrete pole is an open hollow structure, and existing transport equipment does not provide axial restraint for this open end. When the transport frame tilts forward on uphill or downhill sections, the pole will sag under its own weight. Under force, it is very easy to slide out from the front end of the frame along the axis, especially when the pole surface is covered with mud, water or oil, the friction is further reduced, and the risk of sliding out is even higher; third, circumferential tightening and axial anti-derailment often require separate operation and locking, and the operator needs to go around to different parts of the pole multiple times to tighten, the operation process is cumbersome and inefficient, and the tightness between each locking point is difficult to coordinate; fourth, the lead screw or screw used for tightening is prone to self-rotation and loosening under vibration environment, which leads to the gradual decay of pre-tightening force, and the existing equipment lacks an effective anti-reverse retention mechanism.

[0004] Therefore, there is an urgent need to develop an integrated transfer and protection device for ring-shaped concrete poles that can simultaneously achieve circumferential clamping and axial anti-detachment limiting, and is easy to operate and has reliable locking. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an integrated transfer and protection device for ring-shaped concrete poles.

[0006] The integrated transfer and protection device for ring-shaped concrete poles provided in this application adopts the following technical solution: An integrated transport and protection device for a ring-shaped concrete utility pole includes wheels, a support frame, a protective hoop, a tightening assembly, an anti-derailment assembly, and an anti-derailment rope. The support frame is mounted on the axle of the wheel, and the protective hoop is mounted on the support frame. The protective hoop includes an upper hoop body and a lower hoop body hinged together. The upper hoop body has a locking element for locking the upper and lower hoop bodies together, and the lower hoop body is welded to the support frame. The anti-derailment assembly includes a baffle plate with a limiting protrusion on its inner side and supports on both sides of the baffle plate. Each support has a rope hole for the anti-derailment rope to pass through, and a locking element for locking the anti-derailment rope. The anti-derailment rope passes through both supports. The tightening assembly includes a tightening strap and a locking mechanism for... A connecting piece forming a closed loop with a tightening strap is provided, and a support is connected below the tightening strap. Two base plates are provided on the front side of the support frame, and a bidirectional lead screw is rotatably connected between the two base plates. The bidirectional lead screw passes through the two supports and is threadedly connected to them. Positioning blocks are fixed on the front side of each of the two supports. The two ends of the anti-detachment rope pass through the two positioning blocks respectively and are provided with stop heads. The anti-detachment rope is wound around a reversing structure and then connected to the positioning blocks. A crank and ratchet are provided on the outer side of one of the base plates. The crank and ratchet are fixedly sleeved on the end of the bidirectional lead screw. A ratchet block that engages with the ratchet is hinged to the outer side of the base plate. The ratchet block is connected to a protrusion fixed to the base plate via an elastic element, used to keep the ratchet block engaged with the ratchet to limit the reversal of the bidirectional lead screw.

[0007] Furthermore, at least two sets of protective hoops are arranged at longitudinal intervals along the support frame. The upper hoop of each set of protective hoops is connected to a crossbeam on the side away from the hinge axis. The crossbeam connects all the upper hoops into one unit and makes all the upper hoops open or close synchronously.

[0008] Through the above technical solution, multiple sets of protective hoops are arranged longitudinally and spaced along the support frame, which can form multi-point support and restraint along the length of the pole, disperse the self-weight load of the concrete pole, avoid local stress concentration caused by single-point force, reduce the risk of pole collision and cracking under bumpy transportation conditions, and improve the support stability. The crossbeam integrates all the upper hoop bodies into a linkage whole, so that all the upper hoop bodies can be opened and closed synchronously. During operation, only a single operation of the crossbeam is needed to complete the opening and closing of all protective hoops, without the need to flip each set of protective hoops one by one. This greatly simplifies the operation steps before hoisting and unloading, shortens the operation time, and improves the efficiency of construction site operation.

[0009] Furthermore, the limiting protrusions are provided in pairs and are distributed in parallel. Both limiting protrusions are perpendicular to the inner side of the baffle, and the distance between the two limiting protrusions is adapted to the opening of the concrete pole.

[0010] The above technical solution employs a slot-type limiting structure formed by double parallel limiting protrusions and a baffle end face. The limiting protrusions can precisely extend into the open cavity of the concrete pole, locking the pole's open wall thickness between the limiting protrusions and the baffle, achieving axial bidirectional limiting of the pole end. This firmly locks the pole's open edge, effectively preventing the pole from shifting forward or slipping during transport downhill or bumpy conditions. Simultaneously, the vertical arrangement and spacing of the protrusions, adapted to the standard open wall thickness of the pole, ensures uniform contact and stable stress between the limiting structure and the pole end, preventing single-point compressive stress on the concrete open edge and avoiding edge chipping or damage to the pole end, thus providing effective protection for the open end of hollow poles.

[0011] Furthermore, the connector includes two annular sleeves and a U-shaped insert rod. The two annular sleeves are respectively connected to both ends of the tightening band, and both ends of the U-shaped insert rod can be inserted into the two annular sleeves simultaneously to form a closed loop of the tightening band.

[0012] The above technical solution employs a plug-in closed-loop structure using a ring sleeve and a U-shaped insert rod to achieve rapid opening and closing and locking of the tensioning band. Compared to sewn or snap-fit ​​tensioning structures, this structure is easier to assemble and disassemble. During operation, simply align the two ring sleeves and insert them into the U-shaped insert rod to quickly form a complete ring around the pole, significantly reducing the pole covering assembly time. Simultaneously, the U-shaped insert rod's synchronous insertion and limiting at both ends ensures symmetrical and uniform force distribution, preventing the tensioning band from shifting or loosening at both ends, guaranteeing the integrity and uniformity of the circumferential wrapping, and providing a stable force base for subsequent screw tightening. Furthermore, this plug-in structure is easy to assemble and disassemble without jamming or hard wear, can be repeatedly used, is simple and reliable, and is easy to maintain, making it suitable for frequent clamping and transport operations on construction sites.

[0013] Furthermore, the two ends of the bidirectional lead screw have opposite thread directions, and the two supports respectively engage with the positive and negative thread sections of the bidirectional lead screw.

[0014] The above technical solution adopts a bidirectional screw structure with positive and negative teeth. Only one-way rotation of the screw is needed to drive the two supports to move synchronously and symmetrically in opposite directions. Compared with the locking structure with single-sided pulling and single-end driving, this structure can achieve synchronous tightening under force on both sides, so that the clamping force of the fastening component and the tension force of the anti-derailment rope are symmetrical and evenly distributed from left to right, avoiding the pole from shifting to one side and being subjected to uneven load.

[0015] Furthermore, the outer dimensions of the stop head are larger than the diameter of the through hole on the positioning block through which the anti-detachment rope passes.

[0016] Through the above technical solution, the stop head uses the size difference to form a mechanical limit. When the positioning block moves in the opposite direction with the support to perform the tensioning operation, it can reliably block on the outside of the positioning block, realize the tension transmission of the positioning block to the end of the anti-derailment rope, ensure that the driving force of the bidirectional screw can be completely converted into the tension force of the anti-derailment rope, and avoid the end of the anti-derailment rope from slipping directly out of the through hole of the positioning block when it is under tension.

[0017] Furthermore, the ratchet block is provided with a positioning pin, and a positioning hole is provided on the outer side of the base plate. The positioning pin can be inserted into the positioning hole to keep the ratchet block detached from the ratchet wheel.

[0018] With the above technical solution, when it is necessary to loosen the workpiece for unloading, the ratchet block is moved to overcome the force of the elastic element, so that the ratchet block and the ratchet wheel are separated. Then, the positioning pin is inserted into the positioning hole to lock the position of the ratchet block, so that the ratchet block is kept separated from the ratchet wheel, without the need for the operator to continuously hold the ratchet block with external force.

[0019] Furthermore, the reversing structure includes a pulley and a guide rod. A reserved groove is provided on the front side of the support frame, and the pulley is rotatably connected in the reserved groove. A guide groove is provided on the front side of the base plate at an incline. Two guide rods are provided and rotatably connected in the guide groove. The anti-detachment rope extends backward around the positioning block between the pulley and the two guide rods in sequence.

[0020] The above technical solution employs a rotating reversing structure composed of pulleys and guide rods. During the tightening process of the anti-slip rope, rolling friction occurs between the rope and the pulleys and guide rods, significantly reducing frictional resistance during rope pulling, minimizing wear, and extending rope lifespan. The pre-reserved groove provides installation space for the pulley and offers some protection, preventing collisions and interference. The inclined guide groove and guide rod match the routing angle of the anti-slip rope, providing a limiting and guiding function, constraining its movement trajectory, and preventing rope deviation, derailment, or twisting.

[0021] Furthermore, an auxiliary rod is provided between the two base plates. The auxiliary rod passes through the two supports and slides with the supports. There are two auxiliary rods, which are symmetrically distributed about the bidirectional lead screw.

[0022] Through the above technical solution, the two auxiliary rods are symmetrically arranged and together with the bidirectional screw rod form a guide support pair, which plays a role in radial limiting and sliding guidance of the support, constraining the support to only move in a straight line along the axial direction, effectively preventing the support from deflection or jamming when rotating with the bidirectional screw rod, and ensuring that the movement of the two supports is smooth and stable.

[0023] Furthermore, the locking component is a threaded knob, the end of which is threadedly connected to the lower hoop to lock the upper and lower hoops; the tightening component is a locking bolt, the end of which can extend into the rope hole to tighten the anti-slip rope.

[0024] The above technical solution uses a threaded knob as the locking component for the hoop. The upper and lower hoops are locked by screwing in the thread, eliminating the need for additional tools. Operators can lock and unlock the hoop by hand, making the operation simple and quick, and suitable for field construction site conditions. The locking bolts press the anti-derailment rope by directly pressing the end, fixing the position of the anti-derailment rope by the squeezing force. After the bidirectional screw is tensioned, the extension length of the anti-derailment rope can be locked, and the working position of the anti-derailment component can be fixed to prevent the anti-derailment rope from slipping and loosening during transportation. This continuously maintains the axial limiting ability of the open end of the pole and improves the overall vibration resistance of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects: (1) This application realizes the integrated linkage of circumferential clamping and axial anti-derailment. By turning the crank, the bidirectional screw is driven to rotate. While the two supports move towards each other, on the one hand, the supports pull the tensioning strap to form a circumferential clamping and pull down on the outer wall of the pole. On the other hand, the positioning block pulls the two ends of the anti-derailment rope at the same time, so that the anti-derailment rope drives the anti-derailment component to form an axial tension limit on the open end of the pole. A single rotation operation can complete the circumferential clamping and axial anti-derailment at the same time, which is highly efficient. Moreover, the pre-tightening force at both places is output from the same drive source, and the tension is coordinated and consistent.

[0026] (2) The anti-detachment component of this application is adapted to the open structure. The anti-detachment component adopts a U-shaped baffle with a pair of limiting protrusions. When in use, the limiting protrusions are inserted into the open end of the pole and the edge of the open is locked between the two limiting protrusions. This not only prevents the pole from sliding forward along the axis, but also avoids the baffle directly pressing the edge of the open and causing the concrete to collapse, thus forming an effective protection for the end of the pole.

[0027] (3) The anti-slip rope of this application passes through the pulley on the support frame and the two guide rods in the guide groove of the bottom plate in sequence, converting the horizontal tension of the positioning block into the tension force along the direction of the anti-slip rope. At the same time, the pulley and the guide rod are rotatably connected, which greatly reduces the wear of the anti-slip rope during repeated tightening and loosening, and extends its service life.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0034] This application discloses an integrated transfer and protection device for a ring-shaped concrete pole. Please refer to [link / reference]. Figure 1 It includes wheels 1, support frame 2, protective hoop 3, fastening assembly 4, anti-detachment assembly 5, and anti-detachment rope 6.

[0035] Combination Figure 1 and Figure 7 As shown, there are two wheels 1, which are installed at both ends of the same axle. A support frame 2 is fixedly installed on the axle. The support frame 2 is a frame-type welded structure, including two longitudinally extending triangular side beams and a transverse support beam connecting the two side beams, forming a frame for the power pole to be laid flat and supported. The support frame 2 is equipped with protective hoops 3. In this embodiment, three sets of protective hoops 3 are arranged at intervals along the longitudinal direction of the support frame 2. Each set of protective hoops 3 includes an upper hoop 31 and a lower hoop 32. Both the upper hoop 31 and the lower hoop 32 are semi-circular ring structures. They are hinged to each other on one side by a hinge shaft. After hinge, they enclose a circular cavity that fits the outer wall of the concrete power pole. The lower hoop 32 is fixedly installed on the inner side of the support frame 2 and rests on the two triangular side beams of the support frame 2. The inner arc surface of the lower hoop 32 is used to support the concrete power pole.

[0036] It should be noted that a crossbeam 33 is provided on the side of the upper hoop 31 away from the hinge axis. The crossbeam 33 extends longitudinally along the support frame 2, connecting the upper hoop 31 of the three sets of protective hoops 3 into one unit, so that the three sets of upper hoop 31 can be opened or closed synchronously around the hinge axis. During operation, it is only necessary to flip the crossbeam 33 to control the opening and closing of all upper hoop 31 at the same time.

[0037] It should be further noted that each set of upper hoop 31 is also equipped with a knob 34. The knob 34 is a threaded hand-tightening part. When the upper hoop 31 is covered by the lower hoop 32, tightening the knob 34 so that its end is pressed against the corresponding part of the lower hoop 32 can lock the upper hoop 31 and the lower hoop 32, preventing the upper hoop 31 from flipping open on its own during transportation.

[0038] Please see Figure 1 , Figure 5 and Figure 9 The anti-detachment component 5 is used to axially limit the opening at the tip of the concrete utility pole. More specifically, the anti-detachment component 5 includes a U-shaped baffle 51. The inner side of the baffle 51, i.e. the side facing the end face of the pole, is provided with a pair of limiting protrusions 52. The two limiting protrusions 52 are arranged in parallel and are both perpendicular to the inner side of the baffle 51. The distance between the two limiting protrusions 52 is adapted to the wall thickness of the opening at the tip of the concrete utility pole. In some embodiments, the distance may also be slightly greater than the wall thickness to transport concrete utility poles of different sizes.

[0039] In use, the anti-detachment component 5 is pushed in from the tip of the pole, so that both limiting protrusions 52 are located inside the open wall and both ends of the baffle 51 are located outside the open wall, thereby locking the open edge of the pole between the end of the baffle 51 and the limiting protrusions 52, thus restricting the pole from sliding forward axially.

[0040] It should be noted that each side of the baffle 51 is provided with a support 53. The support 53 has a rope hole for the anti-derailment rope 6 to pass through. A locking bolt 54 is provided on the side of the support 53 away from the baffle 51. The end of the locking bolt 54 can extend into the rope hole and press against the anti-derailment rope 6, thereby locking and fixing the passed-through anti-derailment rope 6. It can be understood that the anti-derailment rope 6 is a flexible steel wire rope or a high-strength braided rope, which passes through the rope holes of both supports 53 simultaneously.

[0041] Please see Figure 1 , Figure 3 and Figure 5 The tightening assembly 4 is used to form a circumferential clamping around the outer wall of the pole. Specifically, the tightening assembly 4 includes two integrally set annular sleeves 41 and a tightening band 42. The tightening band 42 is a flexible strip, which can be made of nylon webbing or thin steel strip, and each end of it is connected to an annular sleeve 41. The same insertion rod 43 can be inserted between the two annular sleeves 41. The insertion rod 43 is U-shaped. When in use, after the tightening band 42 is wrapped around the outer wall of the pole, the two annular sleeves 41 are aligned vertically, and the two ends of the U-shaped insertion rod 43 are simultaneously inserted into the two annular sleeves 41, so that the tightening band 42 forms a closed loop. A support 20 is fixedly connected to the lower middle position of the tightening band 42.

[0042] In this embodiment, base plates 7 are fixedly installed on the front sides of the two triangular side beams of the support frame 2. The two base plates 7 are parallel and opposite to each other. A bidirectional lead screw 8 and two auxiliary rods 9 are threaded between the two base plates 7. The bidirectional lead screw 8 and the auxiliary rods 9 are parallel to each other and horizontally arranged. The two auxiliary rods 9 are symmetrically distributed about the bidirectional lead screw 8. The two ends of the bidirectional lead screw 8 have opposite thread directions, and both ends of the bidirectional lead screw 8 are rotatably connected to the two base plates 7 through bearings. Two supports 20 are respectively sleeved on the bidirectional lead screw 8 and the auxiliary rods 9, wherein the bidirectional lead screw 8 and the supports 20 form a threaded transmission engagement, and the auxiliary rods 9 and the supports 20 form a sliding guide engagement. Therefore, when the bidirectional lead screw 8 rotates, the two supports 20 move towards each other or away from each other along the axial direction of the bidirectional lead screw 8 under the guidance of the auxiliary rods 9.

[0043] In this embodiment, a positioning block 21 is fixed to the front side of each of the two supports 20. The positioning block 21 has a through hole for the anti-detachment rope 6 to pass through. The two ends of the anti-detachment rope 6 pass through the through holes of the two positioning blocks 21 respectively, and both ends of the anti-detachment rope 6 are fixedly connected to a stop head 22. The outer dimensions of the stop head 22 are larger than the diameter of the through hole on the positioning block 21, which is used to prevent the end of the anti-detachment rope 6 from coming out of the positioning block 21, so as to ensure that when the positioning blocks 21 move towards each other, the two ends of the anti-detachment rope 6 can be pulled by the stop head 22.

[0044] Combination Figure 4 As shown, the front ends of the two triangular side beams of the support frame 2 are provided with reserved slots 18. A pulley 19 is rotatably connected between the inner walls of the two sides of the reserved slot 18. The axis of the pulley 19 is perpendicular to the longitudinal direction of the support frame 2. The front section of the anti-detachment rope 6 passes through the reserved slot 18 and around the pulley 19, and then extends downward at an angle towards the front bottom plate 7.

[0045] Further integration Figure 6 As shown, a guide groove 14 is inclinedly formed on the front side of the base plate 7. The inclination direction of the guide groove 14 matches the direction in which the anti-slip rope 6 extends from the pulley 19 to the positioning block 21. Two guide rods 15 are rotatably connected between the upper and lower inner walls of the guide groove 14. The two guide rods 15 are parallel to each other and have a gap for the anti-slip rope 6 to pass through. The anti-slip rope 6 extends towards the positioning block 21 after passing between the two guide rods 15. Both the pulley 19 and the guide rods 15 are rotatable roller structures. Their function is to provide low-friction reversing support for the anti-slip rope 6, smoothly converting the horizontal tension of the positioning block 21 into tension along the entire length of the anti-slip rope 6, while preventing the anti-slip rope 6 from directly contacting the sharp edges of the support frame 2 and the base plate 7 and being worn off.

[0046] Further integration Figure 2As shown, a crank 10 and a ratchet 11 are provided on the outer side of one of the base plates 7. Both the crank 10 and the ratchet 11 are fixedly sleeved on the extended end of the bidirectional lead screw 8. The crank 10 is used to manually drive the bidirectional lead screw 8 to rotate, and the ratchet 11 rotates synchronously with the bidirectional lead screw 8. An arc-shaped ratchet block 12 is also hinged on the outer side of the base plate 7 near the ratchet 11. The inner side of the ratchet block 12 is provided with several pawls that are adapted to the tooth shape of the ratchet 11. A protrusion 13 is fixedly connected to the outer side of the ratchet block 12 by a spring. The protrusion 13 is fixedly installed on the base plate 7. The spring applies an elastic thrust to the ratchet block 12 in the direction of the ratchet 11, so that the pawls of the ratchet block 12 are engaged with the ratchet 11. In this engaged state, the ratchet 11 can only rotate in the clockwise direction, i.e., the tightening direction. The counterclockwise direction is blocked by the pawl, thereby realizing the anti-reverse function of the bidirectional lead screw 8. The ratchet block 12 is also provided with a positioning pin 17. A positioning hole 16 is provided on the outer side of the base plate 7 and away from the ratchet wheel 11. When it is necessary to loosen the tightening, the ratchet block 12 is pushed outward to overcome the spring force so that the pawl is disengaged from the ratchet wheel 11, and the positioning pin 17 is inserted into the positioning hole 16 to keep it in a disengaged state. At this time, the bidirectional screw 8 can rotate in the opposite direction, the two supports 20 move in opposite directions, and the tightening belt 42 and the anti-slip rope 6 are released simultaneously.

[0047] The implementation principle of the integrated transfer and protection device for a ring-shaped concrete pole in this application embodiment is as follows: Step 1: Pole positioning and protective hoop closure: Push the transfer equipment to the pole stacking area, loosen knob 34, and simultaneously flip the three sets of upper hoop bodies 31 upwards around the hinge axis via the crossbeam 33, opening the upper part of the protective hoop 3. The concrete pole is then horizontally lifted by a crane and slowly lowered from above onto the inner arc surface of the lower hoop body 32, with the base end (the thicker end) facing the front of the support frame 2 and the tip end (the thinner end) facing the rear. After the pole is in place, flip the crossbeam 33 downwards so that the three sets of upper hoop bodies 31 simultaneously cover the lower hoop body 32. Tighten each knob 34 to lock the upper hoop body 31 and lower hoop body 32 together, thus forming the initial circumferential limit for the pole.

[0048] The second step is the installation of the anti-derailment component and the pre-tensioning of the anti-derailment rope: Unfold the anti-derailment rope 6, and push the anti-derailment component 5 from the base of the pole, so that the pair of limiting protrusions 52 on the inner side of the baffle 51 are inserted into the opening at the base of the pole. The edge of the opening of the pole is locked between the end of the baffle 51 and the limiting protrusions 52. At this time, the anti-derailment rope 6 is in a loose state. The operator holds the baffle 51 with one hand to make it fit tightly against the end face of the pole, and pulls the middle section of the anti-derailment rope 6 with the other hand to keep the anti-derailment rope 6 as taut as possible, reserving a suitable initial tension for subsequent linkage tightening.

[0049] The third step is to insert the tightening assembly around the pole: wrap the tightening band 42 around the pole from below, so that the tightening band 42 covers the circumference of the pole's outer wall. Align the two annular sleeves 41 at both ends of the tightening band 42 above the pole, and insert the two ends of the U-shaped insert 43 into the two annular sleeves 41 simultaneously, so that the tightening band 42 forms a closed loop and is fitted onto the pole's outer wall.

[0050] Step 4: Linkage tightening and anti-derailment tensioning: The operator turns the crank handle 10 clockwise, causing the double-acting screw 8 and ratchet 11 to rotate synchronously. Since the threads at both ends of the double-acting screw 8 rotate in opposite directions, the two supports 20 move towards each other along the axial direction of the double-acting screw 8 under the guidance of the auxiliary rod 9. During this process, the supports 20 exert a downward pulling force on the tightening band 42, causing the tightening band 42 to tightly wrap around the outer wall of the pole and pull it downwards. The pole is firmly fixed inside the protective hoop 3, preventing circumferential rotation or vertical jumping of the pole during transport. Simultaneously, the positioning block 21 fixed to the front of the support 20 moves synchronously towards the opposite side, and the positioning block 21 exerts synchronous tension on both ends of the anti-derailment rope 6 through the stop head 22. Under tension, the anti-slip rope 6 moves sequentially through the pulley 19 and between the two guide rods 15 towards the positioning block 21, further tautening the anti-slip rope 6. The tension of the anti-slip rope 6 is transmitted to the baffle 51 through the support 53, causing the baffle 51 to press tightly against the end face of the pole tip, and the limiting protrusion 52 firmly holds the edge of the opening. It is understood that after the anti-slip rope 6 is taut, it will not hinder the further relative movement of the two supports 20. When the supports 20 continue to move relative to each other, they will only further pull and move the middle section of the anti-slip rope 6, causing the tension of the anti-slip rope 6 to continue to increase until both the tightening strap 42 and the anti-slip rope 6 reach the required pre-tension.

[0051] Step 5: Locking the anti-derailment rope end: After turning the crank 10 until both the tensioning strap 42 and the anti-derailment rope 6 are fully tensioned, tighten the locking bolts 54 on the two supports 53, so that the ends of the locking bolts 54 press against the anti-derailment rope 6, completely locking the relative position of the anti-derailment rope 6 and the support 53. At this point, the circumferential tightening and axial anti-derailment of the pole are complete.

[0052] Anti-loosening during transport: During transport, the ratchet 11 and the ratchet block 12 remain engaged, and the double-acting screw 8 cannot rotate in the opposite direction. Therefore, even if the vehicle bumps or the pole vibrates, the support 20 will not move in opposite directions, and the clamping force of the tensioning strap 42 and the tension of the anti-loosening rope 6 can be maintained continuously without loosening. When the entire transport frame tilts downwards, i.e., downhill, the pole tends to slide forward under the force of its own gravity. However, the baffle 51 and the limiting protrusion 52 of the anti-loosening component 5 are firmly held in front of the support frame 2 by the tensioned anti-loosening rope 6, effectively preventing the pole from sliding forward from inside the protective hoop 3.

[0053] Unloading and loosening process: After the pole is transferred to the pole pit, first loosen the locking bolt 54, then push the ratchet block 12 outward to insert the positioning pin 17 into the positioning hole 16. The ratchet block 12 disengages from the ratchet wheel 11. At this time, turn the crank handle 10 counterclockwise, the double-acting screw 8 rotates in the opposite direction, the two supports 20 move in opposite directions, and the tension strap 42 and the anti-derailment rope 6 are released simultaneously. Pull out the insertion rod 43, unfold the tension strap 42, remove the anti-derailment component 5 from the pole tip, loosen the knob 34 and flip open the upper hoop 31, and the pole can then be lifted away from the transfer equipment by the crane.

[0054] In summary, this invention achieves initial circumferential positioning of the pole through the protective hoop 3, and realizes integrated synchronous tightening of circumferential clamping and axial anti-detachment by driving the tightening assembly 4 and the anti-detachment rope 6 through the linkage of the bidirectional screw 8. The ratchet 11 and ratchet block 12 anti-reverse mechanism maintain the locking force, effectively solving the technical problems of existing pole transfer equipment such as unstable fixing, easy slippage, cumbersome operation, and easy loosening. It has significant advantages such as compact structure, convenient operation, reliable fixing, and high safety.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
