Description

TECHNICAL FIELD

[0001] The application relates to the technical field of circuit construction, in particular to a rope sliding device for power transmission line tower erection. BACKGROUND

[0002] In the process of power transmission line tower erection construction, the tower pieces or tower materials need to be accurately controlled during hoisting to ensure construction safety and quality. The traditional rope sliding operation mode mainly relies on manual operation, that is, the position and direction of the hoisted object are controlled by manually pulling the rope. This mode has many disadvantages. First, manual rope sliding operation requires the construction personnel to continuously exert a large back pulling force, which is extremely labor-intensive, and long-time operation can easily cause the construction personnel to be tired, affecting the construction efficiency. Secondly, due to the limited strength and operation stability of the human body, it is difficult to accurately adjust the tension of the rope and the position of the hoisted object during the control of the rope, which can easily cause the hoisted object to sway and increase the risk of collision with surrounding objects, greatly increasing the safety risk coefficient. In addition, the traditional manual rope sliding operation can only realize the rope sliding function, and cannot effectively perform the rope winding operation. When it is necessary to adjust the length of the rope or wind up the rope, it is very inconvenient, which limits the operation flexibility in the construction process. Therefore, there is an urgent need for a rope control device that can replace manual operation, realize bidirectional operation, and is convenient, safe and reliable, so as to improve the efficiency and safety of power transmission line tower erection construction.

[0017] This invention provides a two-way operation function and enhances operational flexibility. Traditional rope guides can only lower the rope, not retract it, which limits construction operations. The transmission and braking mechanism of the rope guide in this application has the ability to operate in both directions, lowering and retracting the rope. The electric wrench rotates forward to tighten the rope and rotates in the reverse direction to lower it. When operation stops, it can provide double braking to maintain stable tension of the rope. This meets the diverse needs of rope guide operation at different stages of construction. For example, during tower segment hoisting, the length and tension of the rope can be precisely adjusted at any time to maintain the stable posture of the tower segments, improving the accuracy and quality of tower erection.

[0018] The installation of the rope inlet guide and the rope outlet guide ensures that the guide rope accurately enters and exits the pulley. The tension can be adjusted by the rope pressing pulley and the rope pressing lever, which helps to improve the overall quality and stability of the tower erection construction and reduce construction errors and rework caused by improper control of the guide rope.

[0019] The rational connection and cooperation of various components in the transmission and braking mechanism, such as the drive shaft, drive gear ring, ratchet pawl, and locking plate, realizes the functions of power transmission, backstop, and braking. These structural design optimizations have jointly improved the overall performance of the rope guide. Attached Figure Description

[0041] Further preferably, the transmission brake mechanism 30 comprises a speed reduction mechanism, a freewheel mechanism and a dog brake mechanism, the speed reduction mechanism is connected with an external power source, and an output end of the speed reduction mechanism is connected with the working mechanism 40, in the power transmission path, a driving part of the speed reduction mechanism is associated with the freewheel mechanism, so that the freewheel mechanism can control the power transmission direction of the speed reduction mechanism when the speed reduction mechanism transmits power, and the dog brake mechanism is associated with the driving shaft 31 of the speed reduction mechanism.

[0042] Preferably, referring to Figure 2 With Figure 3 , the speed reduction mechanism comprises a driving shaft 31 and a driving gear ring 36, the driving shaft 31 is connected with an external power source, and the driving shaft 31 is sleeved with a driving shaft bearing 311, the driving gear ring 36 is rotated by threadedly cooperating with the spline shaft 43 under the driving of the driving shaft 31 and makes the spline shaft 43 axially move, and the driving gear ring 36 is provided with a rope guide 1 shell cover to protect the transmission brake mechanism 30 to a certain extent; the freewheel mechanism comprises a ratchet wheel 381 and a pawl 382, the ratchet wheel 381 is associated with the spline shaft 43, and the pawl 382 cooperates with the ratchet wheel 381, when the power is transmitted in the forward direction, the ratchet wheel 381 can rotate smoothly, when there is a reverse motion trend, the pawl 382 prevents the ratchet wheel 381 from reversing, and the freewheel is realized; the dog brake mechanism comprises a locking piece 32, a driving shaft end cover 33 and a locking spring 34, the end of the locking spring 34 is embedded into the clasp ring 341 provided in the driving shaft 31 to be fixed, the locking piece 32 is coaxially sleeved on the driving shaft 31 and can move axially, the edge of the locking piece 32 is provided with an embedded structure matched with the column pin 331 on the driving shaft end cover 33, the driving shaft end cover 33 is fixed at one end of the driving shaft 31, and the locking piece 32 and the column pin 331 are embedded to realize braking through the spring tension.

[0043] Specifically, the direction adjusting mechanism 10 is connected with the rope guide base plate 21 through a swivel bolt 15, and then the direction adjusting mechanism 10 can perform free swivel action, and the rope guide 3 is connected around the entry rope wheel 41 and the exit rope wheel 42 arranged on both sides of the rope guide base plate 21, so as to conveniently play a role of guiding the rope guide 3.

[0044] The transmission brake mechanism 30 is attached to the rope guide hanging plate 22, and the transmission brake mechanism 30 is provided with a speed reduction mechanism, a freewheel mechanism and a dog brake mechanism. The driving shaft 31 of the speed reduction mechanism drives the driving gear ring 36 to rotate under the action of external force of an external power source (specifically an electric wrench), the driving gear ring 36 is connected with the spline shaft 43 through six-thread connection, the friction plate 37, the ratchet wheel 381 and the thrust disc 39 are rotated and tightened as a whole, after the end of the rotating-in process, the spline shaft 43 is rotated, the power is transmitted to the entry rope wheel 41 and the exit rope wheel 42, the rope guide 3 is pulled, and the function of tightening the rope guide 3 is realized.

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

[0046] The pawl 32 is a coaxial follower of the driving shaft 31 with an internal hexagonal hole, which can move axially and has an open edge. It can be embedded with two column pins 331 on the driving shaft end cover 33 to realize the stop operation. The embedding is realized under the tension of the locking spring 34, and the embedding stop effect is released only by operating the electric wrench to compress the spring and release the embedding of the pawl 32 and the column pin 331 on the end cover.

The axial direction of the in-rope wheel 41 and the out-rope wheel 42 is fixed and locked, and the circumferential direction can rotate only through the driving of the spline shaft 43 or the traction of the rope 3. The in-rope guide 44 ensures that the rope 3 enters the in-rope wheel 41 accurately, and the out-rope guide 45 cooperates with the rope pressing bolt hook 461 to guide the rope 3.

[0048] Therefore, referring to Figure 7 , in the traditional rope 3 operation of the related art, the hoisted object is controlled by manually pulling the rope 3, F2 represents the tension of the rope 3 itself, and F2 is the force generated by the rope 3 in the process of controlling the hoisted object, which plays a key role in maintaining the stability of the hoisted object and achieving the adjustment of the position. F1 is the back-pulling force provided by the human force, and F1 and F2 work together to ensure that the position and posture of the hoisted object in the hoisting process meet the construction requirements.

[0049] And referring to Figure 8 , when the rope glider 1 in the present application is used for rope 3 operation, the human force is released, and the rope glider 1 can be used to realize the bidirectional operation of releasing and collecting the rope, and the back-pulling force F1 is provided by the rope glider 1, without the need for human force.

[0050] Preferably, the application also provides a working method of the rope runner 1, which is applicable to any of the above-mentioned rope runner 1, and the working method comprises the following steps: connecting the load-bearing frame mechanism 20 of the rope runner 1 with the anchor pile 2 by the connecting component; opening the rope runner hanging plate ring buckle 25, rotating the rope runner hanging plate 22, introducing the rope 3 from the rope-in guide 44 of the working mechanism 40, passing through the rope-in wheel 41, bypassing the direction-changing pulley 11, then passing through the rope-out wheel 42, leading out from the rope-out guide 45, and manually tensioning the rope 3 after pressing the rope 3 by the rope pressing wheel 46 and the rope pressing lever 47, and then buckling the rope runner hanging plate ring buckle 25; inserting the external power source into the drive shaft 31 and pressing the unlocking piece 32 to disengage from the drive shaft end cover 33, starting the external power source, rotating the rope-in wheel 41 and the rope-out wheel 42 by the drive gear ring 36 and the spline shaft 43 to realize rope winding; when the rope needs to be unwound, the external power source is operated in reverse to release the reverse stopping effect of the ratchet wheel 381 and the pawl 382, and the rope 3 is unwound under the tension of the rope 3; when the length of the rope 3 needs to be adjusted, the external power source is started in forward or reverse rotation to realize rope winding or unwinding; when the work is stopped, the ratchet wheel 381 and the pawl 382 reverse stopping system and the locking piece 32 tooth engagement system are used to keep the rope 3 in a stable tension state.

[0051] In a specific electric line tower erection construction, tower piece hoisting operation is needed, at this time, the rope runner 1 in the present application is used to control the position and direction of the tower piece.

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

[0053] In the rope 3 installation and initial tensioning stage, the rope runner hanging plate ring buckle 25 is opened, and the hanging plate is rotated to the appropriate position for easy operation. One end of the rope 3 is accurately rotated into the rope-in wheel 41 from any suitable position through the rope-in guide 44. At this time, the rope-in guide 44 plays a guiding role to ensure that the rope 3 smoothly enters the rope groove of the rope-in wheel 41, avoiding jamming or misalignment of the rope 3 during the entering process.

[0054] Then, the rope 3 is led out from the entry sheave 41 and passes around the deflection sheave 11. The deflection sheave 11 can rotate freely and smoothly changes the direction of the rope 3, causing the rope 3 to follow the predetermined path to the exit sheave 42. After the rope 3 passes around the deflection sheave 11, it is again wound into the exit sheave 42. Similarly, the rope 3 must be correctly positioned in the rope groove of the exit sheave 42, and the rope 3 is passed through the exit sheave guide 45 to further regulate the path of the rope 3, allowing it to be smoothly led out of the rope guide 1. Then, the rope pressing wheel 46 is pressed onto the rope 3, and the rope 3 is kept under a certain tension in the initial state by applying a certain pressure to the rope 3 through the rope pressing wheel 46. Finally, the rope guide hanging plate 22 is reversed so that it is accurately buckled into the hanging pin 23, and the hanging plate ring buckle is locked, forming a stable overall load-bearing structure of the load-bearing frame system of the rope guide 1.

[0055] During the start-up and rope winding operation phase, the construction personnel insert the electric wrench into the drive shaft 31 of the transmission brake mechanism 30 of the rope guide 1 and press the electric wrench, causing the locking piece 32 to disengage from the toothed engagement of the drive shaft end cover 33, thereby eliminating the brake.

[0056] The electric wrench is started, and the rotating power of the electric wrench is transmitted to the spline shaft 43 through the drive gear ring 36. Due to the six-thread connection between the drive gear ring 36 and the spline shaft 43, the power is effectively transmitted, thereby driving the entry sheave 41 and the exit sheave 42 to rotate. In this process, the rotation of the entry sheave 41 and the exit sheave 42 achieves the traction of the rope 3, causing the rope 3 to gradually tighten. As the electric wrench continues to operate, the rope 3 is continuously tightened until it reaches the required tension for the construction, thereby preparing for the subsequent tower piece hoisting operation.

[0057] During the rope unwinding operation phase, when the tower piece is lifted, if it is necessary to loosen the rope 3 to adjust the position or direction of the tower piece during the hoisting operation, the construction personnel operate the electric wrench in reverse. At this time, the drive gear ring 36 rotates in reverse, disengaging from the six-thread of the spline shaft 43, thereby releasing the locking state of the friction plate 37, the ratchet wheel 381, and the thrust disc 39, and the locking action of the ratchet wheel 381 pawl 382 is also released. Under the action of the self-tension of the rope 3, the rope 3 can be smoothly unwound from the exit sheave 42, achieving controlled unwinding operation. In this way, the construction personnel can accurately control the length and speed of the unwinding of the rope 3 according to the actual position of the tower piece and the construction requirements, ensuring that the tower piece always maintains a stable and correct posture during hoisting.

[0058] In the rope adjusting stage, if it is found that the rope 3 is released too much and needs to be collected a little bit, or the rope 3 needs to be further tightened due to the adjustment of the tower blade in position, the construction personnel starts the electric wrench to rotate in the positive direction again. The power of the electric wrench is transmitted to the in- rope wheel 41 and the out- rope wheel 42 through the driving gear ring 36 and the spline shaft 43, so that the in- rope wheel 41 and the out- rope wheel 42 rotate and drag the rope 3, realizing the rope collecting operation. The construction personnel can flexibly control the running time and strength of the electric wrench according to the actual situation, so as to accurately adjust the length and tension of the rope 3, so as to meet the requirements of the tower blade position and posture control in different construction stages.

[0059] In the stop operation stage, when the tower blade hoisting operation is completed or needs to be paused, the rope collector 1 is in the stop operation state. At this time, the reverse stop mechanism composed of the ratchet 381 and the pawl 382 in the transmission brake mechanism 30 plays a role, preventing the rope 3 from relaxing or moving in the opposite direction without control. At the same time, the locking piece 32 recovers the embedding with the column pin 331 of the driving shaft end cover 33 under the action of the locking spring 34, realizing the stop operation. The two sets of brake systems cooperate with each other, double brake, to ensure that the rope 3 can stably maintain the current tension state, prevent the tower blade from moving or shaking due to the loosening of the rope 3, and provide reliable guarantee for the temporary pause in the construction process or the safe state after the operation is completed.
