Description

Technical Field

[0001] The present application relates to the technical field of circuit construction, and in particular to a rope slide for assembling a transmission line tower and a working method thereof. Background Art

[0002] During the construction of the transmission line tower, precise control is required when hoisting tower pieces or tower materials to ensure construction safety and quality. The traditional rope slipping operation method mainly relies on manual operation, that is, the position and direction of the hanging object are controlled by pulling the rope manually. This method has many disadvantages. First, manual rope slipping operation requires construction workers to continuously apply a large back pulling force, which is extremely labor-intensive. Long-term operation can easily cause fatigue of construction workers and affect construction efficiency. Secondly, due to the limited strength and operational stability of humans, it is difficult to accurately adjust the tension of the rope and the position of the hanging object during the control of the rope slipping, which can easily cause the hanging object to shake, increase the risk of collision with surrounding objects, and greatly increase the safety risk factor. In addition, the traditional manual rope slipping operation can only realize the slipping function, and cannot effectively retract the rope. It is very inconvenient when the rope length needs to be adjusted or the rope needs to be retracted, which limits the operational flexibility during the construction process. Therefore, there is an urgent need for a rope slipping control device that can replace manual labor, realize two-way operation, is easy to operate, and is safe and reliable to improve the efficiency and safety of the transmission line tower assembly construction.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] The rope slide in this application document realizes the automatic retraction and extension of the rope, without the need for manpower to directly pull the rope, effectively reducing the labor burden of construction workers and improving the overall construction efficiency.

[0016] The setting of the direction adjustment mechanism ensures smooth guidance of the rope, reasonable force transmission of the load-bearing structure, precise control of the movement of the rope by the transmission and braking mechanism, and effective coordination of the entry and exit and tensioning of the rope by the working mechanism, making the rope sliding operation more stable and controllable, reducing the safety risks caused by human operating errors, ensuring construction safety, and reducing the possibility of accidents.

[0017] It provides two-way operation function and improved operation flexibility. Traditional rope slipping operation can only release the rope but not retract it, which limits the construction operation. The transmission brake mechanism of the rope slipper in this application document has the ability to operate in both directions of releasing and retracting the rope. The electric wrench rotates forward to tighten the rope, and rotates in the reverse direction to release the rope. When the operation is stopped, double braking can be performed to keep the rope stably tensioned. This meets the diverse needs of rope slipping operations at different stages of construction. For example, when hoisting tower pieces, the length and tension of the rope can be accurately adjusted at any time to keep the tower pieces in a stable posture, improving the accuracy and quality of tower assembly construction.

[0018] The setting of the rope entry and rope exit guides ensures that the rope can accurately enter and exit the wheel body. The rope pressing wheel and rope pressing lever can adjust the tension, which helps to improve the overall quality and stability of the tower assembly construction and reduce construction errors and rework caused by improper rope control.

[0019] The reasonable connection and coordination of various components in the transmission braking mechanism, such as the drive shaft, drive gear ring, ratchet pawl, locking plate, etc., realize the power transmission, backstop and braking functions. These structural design optimizations jointly improve the overall performance of the rope slide. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] As a preferred embodiment, the steering mechanism 10 includes: a steering pulley 11 and a steering pulley bracket 12, the steering pulley 11 is connected to the steering pulley bracket 12 through an axis, the axis is specifically a steering pulley shaft 13, and the outer wall of the steering pulley shaft 13 is covered with a steering pulley bearing 14 to ensure the stable connection of the steering pulley 11 relative to the steering pulley bracket 12, the steering pulley bracket 12 is connected to the load-bearing frame mechanism 20 through a slewing bolt 15, the slip rope 3 is wound out by the working mechanism 40, and is smoothly connected to the steering pulley 11, and then the steering mechanism 10 can perform free rotation relative to the load-bearing frame mechanism 20 to guide the slip rope 3.

[0035] As another preferred embodiment, the load-bearing frame mechanism 20 includes: a rope slip base plate 21 and a rope slip hanging plate 22, one end of the rope slip base plate 21 is connected to the adjustment mechanism 10, and the other end is connected to the anchor pile 2, the rope slip hanging plate 22 is protruded relative to the rope slip base plate 21, and the rope slip base plate 21 and the rope slip hanging plate 22 are connected by a spline shaft 43, a working mechanism 40 is provided on the rope slip base plate 21, and a transmission brake mechanism 30 is attached to the rope slip hanging plate 22.

[0036] Further preferably, the load-bearing frame mechanism 20 further includes: a traction plate 24 and a rope slide plate buckle 25, the rope slide base plate 21 is protrudingly provided with a hanging pin 23, one end of the traction plate 24 is fixed to the hanging pin 23, and the other end is used to connect with the anchor pile 2, and preferably, the traction plate 24 is fixedly connected to the anchor pile 2 through a jack rope, the rope slide plate buckle 25 is arranged on the rope slide plate 22, the rope slide plate 22 is clamped with the hanging pin 23, and the rope slide plate buckle 25 cooperates with the hanging pin 23 to fix the rope slide plate 22. Among them, after the rope slide plate buckle 25 is buckled, the rope slide base plate 21 and the rope slide plate 22 form an integral load. The rope 3 force carried by the rope wheel 41 can be transmitted to the anchor pile 2 through the spline shaft 43, the base plate and the hanging plate combination, the hanging pin 23, and the traction plate 24.

[0037] Further preferably, the working mechanism 40 comprises: an in-rope wheel 41 and an out-rope wheel 42, the in-rope wheel 41 and the out-rope wheel 42 are mounted on the rope slide base plate 21 through a spline shaft 43, and the in-rope wheel 41 and the out-rope wheel 42 are placed on both sides of the rope slide base plate 21; wherein the rope 3 is rotated into the in-rope wheel 41, turned over the turning pulley 11, and then rotated into the out-rope wheel 42, and see Figure 6 An offset angle α is set between the incoming rope pulley 41 and the outgoing rope pulley 42. Too large or too small an offset angle α will cause the stability of the slip rope 3 around the incoming rope pulley 41 and the outgoing rope pulley 42 to be low. Therefore, the offset angle α between the incoming rope pulley 41 and the outgoing rope pulley 42 is preferably 31 degrees to ensure the stability of the winding of the slip rope 3.

[0038] Further preferably, the working mechanism 40 also includes: a rope entry guide 44 and a rope exit guide 45. The rope entry guide 44 is located on the rope entry side of the rope entry wheel 41, and is fixedly connected to the rope slip base plate 21, guiding the rope 3 to accurately enter the rope entry wheel 41. The rope exit guide 45 is located on the rope exit side of the rope exit wheel 42, and is fixedly connected to the rope slip base plate 21, guiding the rope 3 to be smoothly led out from the rope exit wheel 42. The positions of the rope entry guide 44 and the rope exit guide 45 correspond to each other.

[0039] Further preferably, the working mechanism 40 also includes: a rope pressing wheel 46 and a rope pressing lever 47. The rope pressing wheel 46 is connected to the rope slip base plate 21 through the rope pressing lever 47. The rope pressing lever 47 can rotate around a fulcrum. The rope pressing wheel 46 is located on the outlet side of the rope guide 45. The rope pressing wheel 46 can be pressed against the rope slip 3 by operating the rope pressing lever 47 to adjust and maintain the tension of the rope slip 3.

[0040] Specifically, see Figure 1 When assembling the rope 3, it is only necessary to open the rope sling hanging plate buckle 25, and then the rope sling hanging plate 22 can be rotated, and any position of the rope sling 3 is screwed into the rope inlet wheel 41 through the rope inlet guide 44, and then the rope sling 3 is screwed into the rope outlet wheel 42 through the rope outlet guide 45 over the turning pulley 11, and the rope pressing bolt hook 461 is unlocked, and then the rope pressing wheel 46 is driven to press the rope pressing lever 47, and the rope is manually tensioned, and then the rope sling hanging plate 22 is reversed and buckled into the hanging pin 23, and the rope sling hanging plate buckle 25 is locked to complete the assembly of the rope sling 3. Figure 1 Taking the perspective as an example, at this time, the engagement of the rope slide hanging plate buckle 25 stops the rope slide hanging plate 22 from rotating counterclockwise, and at the same time, the engagement between the rope slide hanging plate 22 and the hanging pin 23 stops the rope slide 1 from rotating clockwise, thereby fixing the rope slide hanging plate 22 relative to the rope slide base plate 21.

[0041] Further preferably, the transmission brake mechanism 30 includes: a reduction mechanism, a check mechanism and a tooth brake mechanism. The reduction mechanism is connected to an external power source, and its output end is connected to the working mechanism 40. On the power transmission path, the driving component of the reduction mechanism and the check mechanism are interconnected, so that when the reduction mechanism transmits power, the check mechanism can control its power transmission direction, and the tooth brake mechanism is associated with the drive shaft 31 of the reduction mechanism.

[0042] Preferably, see Figure 2 and Figure 3 The reduction mechanism includes a drive shaft 31 and a drive gear ring 36. The drive shaft 31 is connected to an external power source, and a drive shaft bearing 311 is placed on the outer sleeve of the drive shaft 31. The drive gear ring 36 rotates under the drive shaft 31 and causes the spline shaft 43 to move axially by threading with the spline shaft 43. A shell cover of the rope slipper 1 is arranged outside the drive gear ring 36 to protect the transmission brake mechanism 30 to a certain extent. The check mechanism includes a ratchet 381 and a pawl 382. The ratchet 381 is associated with the spline shaft 43, and the pawl 382 cooperates with the ratchet 381. When the power is transmitted in the forward direction, the ratchet 381 It can rotate smoothly. When there is a tendency of reverse movement, the pawl 382 prevents the ratchet 381 from reversing, thereby achieving reverse stopping. The toothed braking mechanism includes a locking plate 32, a drive shaft end cover 33 and a locking spring 34. The end of the locking spring 34 is embedded in a retaining ring 341 opened on the drive shaft 31 for fixation. The locking plate 32 is coaxially mounted on the drive shaft 31 and can move axially. The edge of the locking plate 32 is provided with an embedding structure adapted to the column pin 331 on the drive shaft end cover 33. The drive shaft end cover 33 is fixed to one end of the drive shaft 31. The locking plate 32 and the column pin 331 are embedded through spring tension to achieve braking.

[0043] Specifically, the direction adjustment mechanism 10 is connected to the rope slide base plate 21 through the slewing bolt 15, so that the direction adjustment mechanism 10 can perform free rotation, smoothly connecting the rope 3 that passes over the rope inlet pulley 41 and the rope outlet pulley 42 arranged on both sides of the rope slide base plate 21, and conveniently guides the rope 3.

[0044] The transmission brake mechanism 30 is attached to the rope slide hanging plate 22, and the transmission brake mechanism 30 is equipped with a speed reduction mechanism, a check mechanism and a tooth brake mechanism. Under the external force of an external power source (specifically an electric wrench), the driving shaft 31 of the speed reduction mechanism drives the driving ring gear 36 to rotate, and the driving ring gear 36 and the spline shaft 43 are screwed in with a six-head thread connection, and the friction plate 37, the ratchet 381, and the thrust plate 39 are screwed into one. After the screwing process is completed, the spline shaft 43 is driven to rotate, and the power is transmitted to the rope inlet wheel 41 and the rope outlet wheel 42, and the rope slide 3 is pulled to achieve the function of tightening the rope slide 3.

[0045] When the electric wrench rotates in the reverse direction, the driving gear ring 36 will be unscrewed from the six-threaded spline shaft 43, releasing the locking state of the friction plate 37, the ratchet 381 and the thrust plate 39. At this time, the locking effect of the ratchet 381 pawl 382 is released, and under the action of the tension of the slip rope 3, the slip rope 3 realizes the rope-releasing effect, realizing the rope-releasing operation of the slip rope 3. The check mechanism is the ratchet 381 pawl 382 mechanism in the above operation process.

[0046] The toothed brake mechanism is installed on the drive shaft 31: the locking piece 32 is a hexagonal hole coaxially following the drive shaft 31, and can move axially. Its edge is opened and can be engaged with the two pins 331 on the drive shaft end cover 33 to achieve the stopping operation. The engagement is achieved under the tension of the locking spring 34. To release the locking stop, just operate the electric wrench to press down, compress the spring, and release the engagement between the locking piece 32 and the pins 331 on the end cover.

[0047] The rope pulley 41 and the rope pulley 42 of the working mechanism 40 are supported on the rope slide base plate 21 through the spline shaft 43, the spline shaft bearing 49 and the spline shaft end cover 48. One end of the spline shaft 43 is locked by the end cover, and the other end is locked by the shaft shoulder. The inner side of the shaft shoulder lock is also equipped with a rope slide hanging plate 22. The axial direction of the rope pulley 41 and the rope pulley 42 is fixed and locked, and the circumferential rotation can only be rotated by the spline shaft 43 or the rope 3. The rope guide 44 ensures that the rope enters the rope pulley 41 accurately, and the rope guide 45 cooperates with the rope pressure bolt hook 461 to guide the rope 3.

[0048] Therefore, see Figure 7 In the traditional rope slip 3 operation of the related technology, the lifting object is controlled by pulling the rope slip 3 manually. The force represented by F2 is the tension borne by the rope slip 3 itself. F2 is the force along the rope slip 3 generated in the process of controlling the lifting object. This force plays a key role in maintaining the stability of the lifting object and achieving the adjustment in place. F1 is the back pulling force provided by manpower. F1 and F2 work together to ensure that the position and posture of the lifting object during the lifting process meet the construction requirements.

[0049] For details, see Figure 8 When the rope slip device 1 in the present application document is used for rope slipping 3, manpower is liberated, and the use of the rope slip device 1 can realize two-way operations of rope slipping and rope retracting, and the back pulling force F1 is provided by the rope slip device 1 without the need for manpower.

[0050] Preferably, the present application also provides a working method of a rope slipper 1, which is applicable to any one of the rope slipper 1s mentioned above, and the working method comprises: connecting the load-bearing frame mechanism 20 of the rope slipper 1 with the anchor pile 2 by a connecting component; opening the rope slipper hanging plate buckle 25, rotating the rope slipper hanging plate 22, introducing the rope 3 from the rope inlet guide 44 of the working mechanism 40, passing through the rope inlet wheel 41, bypassing the turning pulley 11, and then passing through the rope outlet wheel 42, leading out from the rope outlet guide 45, manually tensioning the rope 3 after crimping it through the rope pressing wheel 46 and the rope pressing lever 47, and buckling the rope slipper hanging plate buckle 25; The power source is inserted into the drive shaft 31 and pressed down to release the engagement between the locking plate 32 and the drive shaft end cover 33, and the external power source is started to drive the ring gear 36 and the spline shaft 43 to drive the rope inlet wheel 41 and the rope outlet wheel 42 to rotate to achieve rope collection; when it is necessary to release the rope, the external power source is operated to reverse, and the check effect of the ratchet 381 and the pawl 382 is released, so that the rope can be released under the tension of the rope 3; when it is necessary to adjust the length of the rope 3, the external power source is started to rotate forward or reversely according to the needs to achieve rope collection or rope release; when the operation is stopped, the ratchet 381, the pawl 382 check system and the locking plate 32 tooth system are relied on to keep the rope 3 in a stable tensioned state.

[0051] When a specific electric line tower is being assembled and constructed, it is necessary to carry out a tower segment hoisting operation. At this time, the rope slide 1 in the present application document is used to control the position and direction of the tower segment.

[0052] In the preparation stage, the construction personnel first firmly tie one end of the lifting rope to the corresponding position of the rope slide 1 (such as the traction plate 24 designed for connecting the lifting rope on the rope slide base plate 21), and the other end is tightly connected to the pre-set anchor pile 2. Ensure that the connection between the rope slide 1 and the anchor pile 2 is firm and reliable, and can withstand various forces generated during the subsequent rope slide 3 operation.

[0053] During the installation and initial tensioning of the rope 3, the rope hook 25 is opened and the hook is rotated to a suitable position for easy operation. One end of the rope 3 is accurately screwed into the rope entry wheel 41 through the rope entry guide 44 from any suitable position. At this time, the rope entry guide 44 plays a guiding role to ensure that the rope 3 smoothly enters the rope groove of the rope entry wheel 41, avoiding the rope 3 from getting stuck or misaligned during the entry process.

[0054] Next, the rope 3 is led out from the rope inlet pulley 41 and made to pass around the turning pulley 11. The turning pulley 11 can rotate freely and smoothly change the direction of the rope 3 so that the rope 3 goes to the rope outlet pulley 42 according to the predetermined path. After the rope 3 passes around the turning pulley 11, it is screwed into the rope outlet pulley 42. Similarly, it is necessary to ensure that the rope 3 is correctly positioned in the rope groove of the rope outlet pulley 42, and the rope 3 passes through the rope outlet guide 45 to further regulate the direction of the rope 3 so that it can be smoothly led out of the rope slide 1. After that, the rope pressing wheel 46 is pressed on the rope 3, and a certain pressure is applied to the rope 3 through the rope pressing wheel 46, so that the rope 3 maintains a certain tension in the initial state. Finally, the rope slide hanging plate 22 is reversed to accurately buckle it into the hanging pin 23, and the hanging plate ring buckle is locked, so that the load-bearing frame system of the rope slide 1 forms a stable integral load-bearing structure.

[0055] During the start-up and rope-collecting operation, the construction personnel insert the electric wrench into the drive shaft 31 of the transmission brake mechanism 30 of the rope slide 1 and press the electric wrench to release the tooth connection between the locking plate 32 and the drive shaft end cover 33, thereby eliminating the brake.

[0056] The electric wrench is started, and the pile-turning power of the electric wrench is transmitted to the spline shaft 43 through the driving gear ring 36. Since the driving gear ring 36 is connected to the spline shaft 43 by a six-head thread, the power can be effectively transmitted, thereby driving the in-rope pulley 41 and the out-rope pulley 42 to rotate. In this process, the rotation of the in-rope pulley 41 and the out-rope pulley 42 realizes the traction of the slip rope 3, so that the slip rope 3 is gradually tightened. As the electric wrench continues to operate, the slip rope 3 is continuously tightened until the tension required for construction is reached, thereby preparing for the subsequent tower piece hoisting operation.

[0057] During the rope-releasing operation, after the tower is lifted, during the lifting operation, if it is necessary to loosen the rope 3 to adjust the position or direction of the tower, the construction personnel operate the electric wrench to reverse. At this time, the driving gear ring 36 rotates in the opposite direction and unscrews from the six-threaded spline shaft 43, releasing the locking state of the friction plate 37, the ratchet 381, and the thrust plate 39, and at the same time, the locking effect of the ratchet 381 pawl 382 is also released. Under the action of the tension of the rope 3 itself, the rope 3 can be smoothly released from the rope pulley 42, realizing the controlled rope-releasing operation. In this way, the construction personnel can accurately control the release length and speed of the rope 3 according to the actual position of the tower and the construction requirements, ensuring that the tower always maintains a stable and correct posture during the lifting process.

[0058] In the rope adjustment stage, during the construction process, if it is found that the slip rope 3 is released too much and needs to be collected, or if the slip rope 3 needs to be further tightened due to the adjustment of the tower piece, the construction personnel will start the electric wrench to rotate forward again. The power of the electric wrench is again transmitted to the rope input wheel 41 and the rope output wheel 42 through the driving gear ring 36 and the spline shaft 43, so that the rope input wheel 41 and the rope output wheel 42 rotate and drag the slip rope 3 to realize the rope collection operation. The construction personnel can flexibly control the operation time and force of the electric wrench according to the actual situation, so as to accurately adjust the length and tension of the slip rope 3 to meet the requirements of the tower piece position and posture control at different construction stages.

[0059] In the stop operation stage, when the tower piece hoisting operation is completed or needs to be suspended, the rope jack 1 is in a stop operation state. At this time, the check mechanism composed of the ratchet 381 and the pawl 382 in the transmission brake mechanism 30 plays a role to prevent the rope jack 3 from loosening or moving in the opposite direction without control. At the same time, under the action of the locking spring 34, the locking plate 32 resumes the engagement with the pin 331 of the drive shaft end cover 33 to achieve the stopping operation. The two sets of braking systems cooperate with each other and perform double braking to ensure that the rope jack 3 can stably maintain the current tension state, prevent the tower piece from being displaced or shaken due to the loosening of the rope jack 3, and provide reliable protection for temporary pauses during construction or safety after the operation is completed.
