Description

Technical Field

[0001] The invention relates to the field of tension wire construction, in particular to a wire laying pulley and a method for facilitating the passage of a pulling walking board during wire construction. Background Art

[0002] The tension wire laying method is a wire laying method widely used in wire laying construction. It uses construction machinery such as traction machines and tension machines to lay out the guide wires and ground wires, so that they are off the ground and obstacles during the laying process and are in an overhead state. In general, it is necessary to use a traction board to pull the conductor through the wire laying pulley to complete the conductor laying work, and it is necessary to comply with relevant regulations. However, when the traction board passes through the wire laying pulley, it will encounter greater resistance, resulting in a lack of stability in the working process. The traction board will swing to a large extent, which is prone to construction accidents such as wire jumping and traction board flipping, and even wire breakage, endangering the safety of construction personnel, reducing construction efficiency, and causing the line erection work to be unable to proceed normally.

[0003] When using the current tension stringing method for stringing construction, it is rarely considered to change the positional relationship between the traction board and the wire pulley to facilitate the passage of the traction board. During the tension stringing construction process, visual observation by construction workers alone is not enough to reduce the risk of accidents. Secondly, when the traction board flips over, the conductor jumps, and other construction accidents occur, it will also affect the already erected lines, resulting in the inability to ensure the safety of the stringing construction workers and affecting work efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a wire-laying pulley and method that facilitates the passage of a traction board during wire-laying construction. When the traction board passes through the wire-laying pulley, the pulley diameter and bracket length of the wire-laying pulley can be changed to reduce the resistance of the traction board passing through the wire-laying pulley, thereby ensuring the safety of construction personnel and the efficiency of wire-laying construction. At the same time, by real-time monitoring of the position of the traction board, the number of manual observations under the tower is reduced, manpower and material resources are saved, and the accuracy and economy of construction are improved.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A wire laying pulley for facilitating the passage of a walking board during wire laying construction, comprising a pulley assembly and a bracket assembly; The pulley assembly includes a reducing pulley, a driving wheel is provided on one side of the reducing pulley, and a driven wheel is provided on the other side of the reducing pulley; the driving wheel includes a first connecting disk, and a plurality of linear grooves are provided on the circumferential direction of the first connecting disk; the reducing pulley includes a second connecting disk, and a plurality of arc grooves are provided on the circumferential direction of the second connecting disk, and the number and position of the linear grooves and the arc grooves correspond and partially overlap; a plurality of pulley blocks matching the arc grooves are provided on the outer side of the second connecting disk, and the inner side of each pulley block is connected to one end of a support rod, and the other end of the support rod is connected to a sliding rod, and one end of the sliding rod is freely inserted into the arc groove, and the other end is freely inserted into the linear groove; The variable diameter pulley and the driving wheel are driven by independent motors to rotate at differential speed or at the same speed; The support assembly includes a top plate and side rods, wherein the top plate is fixed to the upper ends of the side rods on the left and right sides; the side rods include telescopic rods, wherein the lower ends of the telescopic rods are slidably matched with the supports and driven to move up and down by electric push rods in the supports.

[0006] The reducing pulley is installed on the reducing pulley connecting rod, the driving wheel is installed on the driving wheel connecting rod, and the driven wheel is installed on the driven wheel connecting rod; wherein the reducing pulley connecting rod passes through the driving wheel connecting rod and the driven wheel connecting rod, and the driving wheel connecting rod, the reducing pulley connecting rod, and the driven wheel connecting rod and the reducing pulley connecting rod are all connected through bearings; the driving wheel connecting rod is connected to the output end of the driving wheel motor; the reducing pulley connecting rod passes through the driven wheel connecting rod and is connected to the output end of the reducing pulley motor.

[0007] The arc groove is arc-shaped, and one end of the arc groove close to the center overlaps with the linear groove in the initial state, and one end of the arc groove close to the edge of the second connecting disk points in the opposite direction to the rotation direction.

[0008] The linear groove is straight, and an extension line of one end of the linear groove passes through the center, and the other end extends radially outward.

[0009] An information processing module and a battery module are installed in the support of the side rod. The information processing module includes a microcontroller and a wireless signal transmitter. The microcontroller is used to issue instructions to the electric push rod, the driving wheel motor and the variable diameter pulley motor.

[0010] A solar charging panel, a camera and an infrared ranging module are installed on the top plate.

[0011] A method for preventing a traction walking board from over-laying a line pulley accident comprises the following steps: Step 1: Equipment installation and threshold setting: The wire-laying pulley is connected to the pole tower through the connection hole, the battery module is charged before construction, and the diameter of the variable pulley of the wire-laying pulley and the telescopic length of the side rod are preset through the handheld terminal to adapt them to the actual project; Step 2: According to the actual situation on site, the construction personnel can use the threshold set in advance to enable the wire-laying pulley to complete the operation autonomously; at the same time, in order to complete the wiring construction work more accurately, the spatial position information between the traction board and the wire-laying pulley can be monitored in real time through the camera and the infrared ranging module, and the signal is sent to the handheld terminal signal receiver through the built-in wireless signal transmitter, and monitored on the handheld terminal, and the action signal is sent to the microcontroller in the wire-laying pulley through the handheld terminal signal transmitter; Step three, when the microcontroller receives the action signal, it sends action instructions to the driving wheel motor, the variable diameter motor and the electric push rod; the driving wheel motor drives the driving wheel to rotate, and the variable diameter motor drives the variable diameter pulley to rotate, so that a speed difference is generated between the driving wheel and the variable diameter pulley; the pulley block moves, and the diameter of the variable diameter pulley changes; the electric push rod drives the telescopic rod to move, and changes the length of the telescopic rod; by changing the diameter of the variable diameter pulley and the length of the telescopic rod, the resistance when the walking plate is pulled over the line-paying pulley is reduced.

[0012] The wire-paying pulley monitors the spatial position information between the traction walkway and the wire-paying pulley in real time through the camera and the infrared ranging module. When the traction walkway contacts the wire-paying pulley, the diameter of the reducing pulley increases; when the sub-conductor connected to the traction walkway enters the driving wheel and the driven wheel, the diameter of the reducing pulley decreases; and when the diameter of the reducing pulley increases, the speed of the driving wheel is faster; when the diameter of the reducing pulley decreases, the speed of the reducing pulley is faster; the telescopic rod extends when the diameter of the reducing pulley increases, and retracts when the diameter of the reducing pulley decreases.

[0013] The present invention provides a wire laying pulley and method for facilitating the passage of a pulling walking board during wire laying construction, which has the following technical effects: 1) By changing the positional relationship between the traction board and the wire-laying pulley, the resistance of the traction board passing through the wire-laying pulley is reduced to facilitate the passage of the traction board, avoid construction accidents such as flipping of the traction board and wire jumping, and also improve work efficiency and safety.

[0014] 2) By installing the wire-laying pulley on the pole tower, the stability of the wire-laying pulley can be further ensured, and accidents such as overturning and large-scale transmission line movement caused by the traction board passing through the wire-laying pulley can be avoided, thereby further improving construction efficiency.

[0015] 3) Since the cable construction often takes some time to complete, this device uses solar charging panels to charge the battery pack to avoid frequently removing the cable pulley for charging.

[0016] 4) This device adjusts the pulley diameter by changing the relative rotation speed between the pulleys, which will not affect the wiring construction process, and the data can be monitored in real time to prevent accidents.

[0017] 5) The first traction end of the traction board is connected to the traction line, and the second traction end of the traction board is connected to the sub-conductor. The traction line passes through the wheel groove of the variable diameter pulley, and the two sub-conductors pass through the wheel grooves of the driving wheel and the driven wheel respectively. By utilizing the speed difference between the variable diameter pulley and the driving wheel, the variable diameter pulley changes its diameter when the traction board passes, which facilitates the traction board to pass and reduces the possibility of accidents.

DETAILED DESCRIPTION

[0032] like Figure 1 As shown, a wire laying pulley for facilitating the passage of a walking board during wire laying construction comprises a pulley assembly and a bracket assembly.

[0033] The pulley assembly consists of two parts: a pulley block and a differential drive rod.

[0034] like Figure 1 As shown, the pulley block includes a sizing pulley 1 located on both sides and a reducing pulley 2 in the middle. The sizing pulley is further divided into a driving wheel 3 and a driven wheel 4.

[0035] like Figure 8 As shown, the driving wheel 3 includes a first connecting disk 6 , and a plurality of linear grooves 5 are circumferentially arranged on the first connecting disk 6 .

[0036] like Figure 6-7 As shown, the variable diameter pulley 2 includes an inner plate 7, the inner plate 7 includes a second connecting plate 9, and the second connecting plate 9 is circumferentially provided with a plurality of arc grooves 10; a plurality of pulley blocks 8 are provided on the outer side of the inner plate 7, the number of which matches the arc grooves 10, and the inner side of each pulley block 8 is connected to one end of a support rod 11, and the other end of the support rod 11 is connected to a sliding rod 12, and one end of the sliding rod 12 is freely inserted into the arc groove 10, and the other end is freely inserted into the linear groove 5.

[0037] By locating one end of the slide bar 12 in the arc groove 10 and the other end in the linear groove 5, when the driving wheel 3 and the reducing pulley 2 rotate at the same speed, the slide bar 12 is limited by the linear groove 5 and the arc groove 10 and remains stationary; when a speed difference occurs between the driving wheel 3 and the reducing pulley 2, the arc groove 10 pushes the slide bar 12 to move upward or downward along the linear groove 5, thereby causing the pulley block 8 to move and the diameter of the reducing pulley 2 to change.

[0038] The differential drive rod comprises two parts: a motor and a connecting rod.

[0039] like Fig. 9 As shown, the electric motor includes a driving wheel motor 13 and a variable diameter pulley motor 14 .

[0040] like Fig. 9 As shown, the connecting rod includes a driving wheel connecting rod 15, a reducing pulley connecting rod 16 and a driven wheel connecting rod 17. The reducing pulley connecting rod 16 passes through the driving wheel connecting rod 15 and the driven wheel connecting rod 17; the driving wheel connecting rod 15, the reducing pulley connecting rod 16, and the driven wheel connecting rod 17 and the reducing pulley connecting rod 16 are all connected through bearings 18.

[0041] like Figure 9-10 As shown, the driving wheel connecting rod 15 is directly connected to the driving wheel motor 13, and the reducing pulley connecting rod 16 is connected to the reducing pulley motor 14 after passing through the interior of the driven wheel connecting rod 17.

[0042] The driving wheel connecting rod 15 and the reducing pulley connecting rod 16 are connected by a bearing 18, which reduces the friction between the driving wheel connecting rod 15 and the reducing pulley connecting rod 16, making it easier for the driving wheel motor 13 and the reducing pulley motor 14 to control the speed of the driving wheel 3 and the reducing pulley 2.

[0043] like Figure 1-3 As shown, the bracket assembly includes a top plate 19 and a side rod 20 , and the top plate 19 is fixed to the upper part of the side rod 20 by screws 24 .

[0044] like Figure 3 As shown, a solar charging panel 21 and a video monitoring module are installed on the top plate 19. The video monitoring module includes a camera 22 and an infrared ranging module 23.

[0045] The wire-releasing pulley monitors the positional relationship between the traction board and the wire-releasing pulley in real time through the camera 22 , and measures the distance between the traction board and the wire-releasing pulley through the infrared distance measuring module 23 .

[0046] like Figure 5 As shown, the side rod 20 includes a telescopic rod 25, an electric push rod 26, a battery module 27 and an information processing module 28. The end of the telescopic rod 25 is directly connected to the electric push rod 26, the electric push rod 26 is fixed above the information processing module 28, and the battery module 27 is located below the information processing module 28.

[0047] like Fig.12 As shown, the information processing module 28 contains a microcontroller 33 and a built-in wireless signal transmitter 34. The microcontroller 33 directly issues action instructions to the electric push rod 26, the driving wheel motor 13 and the variable diameter pulley motor 14 through preset values, and can also be used to receive action signals issued by the handheld signal transmitter 36.

[0048] The cameras 22 and the infrared distance measuring modules 23 are arranged in a group on both sides of the line-laying pulley. The cameras 22 are respectively the first monitoring camera 32 and the second monitoring camera 30 , and the infrared distance measuring modules 23 are respectively the first infrared distance measuring device 31 and the second infrared distance measuring device 29 .

[0049] The battery module 27 can be charged by the solar charging panel 21, or can be directly charged by wire before construction.

[0050] The microcontroller 33 exchanges information with the construction personnel through the ground handheld terminal 37. The handheld terminal 37 controls the first monitoring camera 32, the second monitoring camera 30, the first infrared rangefinder 31, and the second infrared rangefinder 29 respectively through the perspective switching key 38, and controls the speed of the driving wheel motor 13 and the variable diameter pulley motor 14 through the speed control key 39.

[0051] A method for preventing an accident in which a traction board passes through a wire-laying pulley during a wire-laying construction, comprising the following steps: Step 1: Install the device and set the threshold: Figure 1 As shown, the wire-laying pulley is connected to the pole tower via a connecting hole 37, the battery module 27 is charged before construction, and the diameter of the variable pulley 2 and the telescopic length of the side rod 20 are preset via a handheld terminal 37 so that they can adapt to the actual project.

[0052] Step 2. According to the actual situation on site, the construction personnel can use the threshold set in advance to enable the wire-laying pulley to complete the operation autonomously; at the same time, in order to complete the wiring construction work more accurately, the spatial position information between the traction walkway and the wire-laying pulley can be monitored in real time through the camera 22 and the infrared ranging module 23, and the signal is sent to the handheld terminal signal receiver 35 through the built-in wireless signal transmitter 34, monitored on the handheld terminal 37, and the action signal is sent to the microcontroller 33 in the wire-laying pulley through the handheld terminal signal transmitter 36.

[0053] Step 3: After receiving the action signal, the microcontroller 33 issues an action command to the driving wheel motor 13, the variable diameter motor 14 and the electric push rod 26. The driving wheel motor 13 drives the driving wheel 3 to rotate, and the variable diameter motor 14 drives the variable diameter pulley 2 to rotate, so that the driving wheel 3 and the variable diameter pulley 2 have a speed difference, the pulley block 8 moves, and the diameter of the variable diameter pulley 2 changes; the electric push rod 26 drives the telescopic rod 25 to move and change the length of the telescopic rod 25; by changing the diameter of the variable diameter pulley 2 and the length of the telescopic rod 25, the resistance when the walking board is pulled over the wire pulley is reduced, thereby improving the safety and efficiency of the wire stringing construction.

[0054] During specific adjustments, the wire-paying pulley monitors the spatial position information between the traction walking plate and the wire-paying pulley in real time through the camera 22 and the infrared ranging module 23. When the traction walking plate contacts the wire-paying pulley, the diameter of the reducing pulley 2 increases; when the sub-conductor connected to the traction walking plate enters the driving wheel 3 and the driven wheel 4, the diameter of the reducing pulley 2 decreases.

[0055] When the diameter of the reducing pulley 2 increases, the speed of the driving wheel 3 increases; when the diameter of the reducing pulley 2 decreases, the speed of the reducing pulley 2 increases.

[0056] When the diameter of the reducing pulley 2 increases, the telescopic rod 25 extends, and when the diameter of the reducing pulley 2 decreases, the telescopic rod 25 retracts.
