Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction tools, in particular to an electrically controlled bidirectional braking wire-paying pulley. Background Art

[0002] During transmission line construction, the safety of the cable-laying trolley, a core device for tensioning and stringing cables, is directly linked to the safety of both operators and equipment. Existing technologies primarily use pulley blocks to guide cables. However, under abnormal operating conditions such as a broken traction rope, a malfunctioning winch, or an operator error, the cable can slip forward at excessive speed or retract in the reverse direction due to inertia, potentially causing it to fall, damage equipment, or even casualties. Existing solutions often utilize mechanical one-way brakes, such as those that use gravity or spring force to drive brake blocks to clamp the cable. However, these solutions rely on mechanical transmission control, resulting in response lag. Mechanical brakes rely on physical contact triggering, making it difficult to respond to overspeed or reverse motion within milliseconds. Summary of the Invention

[0013] Preferably, a protective cover is provided outside the electronically controlled forward overspeed braking assembly and the electronically controlled reverse overspeed braking assembly.

[0014] The technical solution adopted by the present invention can achieve the following beneficial effects: 1. The present invention provides an electrically controlled bidirectional braking wire-laying pulley, comprising a wire-laying pulley body, an electrically controlled forward overspeed braking assembly, and an electrically controlled reverse overspeed braking assembly, wherein the electrically controlled forward overspeed braking assembly and the electrically controlled reverse overspeed braking assembly are respectively arranged on opposite sides of the wire-laying pulley body along the direction of the cable; a braking module and a reset assembly are both provided in the electrically controlled forward overspeed braking assembly and the electrically controlled reverse overspeed braking assembly, the braking module being connected to the reset assembly, and the braking module realizes forward and / or reverse braking by clamping the cable; the electrically controlled forward overspeed braking assembly and the electrically controlled reverse overspeed braking assembly are both provided with a laser speed sensor and a pressure feedback module, and the reset assembly receives the signal of the laser speed sensor To realize the braking operation of the brake module, the pressure feedback module is set on the brake module and contacts the cable when braking is realized; this solution can realize intelligent overspeed protection in the bidirectional movement of the cable, and solve the risk of unidirectional braking failure of the traditional pulley through the symmetrically arranged bidirectional brake components; the laser speed sensor monitors the cable speed in real time. When the cable transmission speed exceeds the set threshold, the laser speed sensor immediately transmits a signal to the reset component, and the reset component triggers the brake module to brake, thereby improving the response accuracy and solving the problem of delayed response of the traditional wire-laying pulley with braking function during braking. The pressure feedback module dynamically monitors the clamping force during braking to avoid overload damage to the cable, doubly ensuring construction safety.

[0015] 2. The electronically controlled forward overspeed braking assembly and the electronically controlled reverse overspeed braking assembly are also equipped with a wireless communication module, which transmits data from the laser speed sensor and the pressure feedback module to a remote monitoring terminal. Through the wireless communication module, remote monitoring of braking data is achieved, and construction personnel can obtain parameters such as speed and pressure in real time, facilitating rapid identification of abnormalities (such as overspeeding without triggering braking).

Through the coil spring drive and the curved motion trajectory, the passability of the middle cable is ensured while the overall device size is small.

[0017] 4.

[0018] 5. Through the setting of the coil spring group and the reset assembly in the lower component, when braking is required, the electric-controlled ratchet assembly in the reset assembly receives the electrical signal from the laser speed sensor, automatically releases the ratchet to loosen the traction rope, and the lower brake slider moves to the braking position on the lower rail under the tension of the coil spring group. The entire braking process is fully automatic and does not require human intervention, reducing the response lag between traditional mechanical structures, making braking more timely, and significantly reducing the occurrence of safety accidents in tension line operations.

[0019] 6. Through the coordinated control of the safety interlock device and the position detection sensor, when it is detected that the lower brake slider has not been fully reset, the pulley is prohibited from entering the next working cycle, effectively preventing the risk of misoperation caused by incomplete reset, improving system safety, and abnormal status alarms are issued through the wireless module, complying with safety construction specifications.

[0020] 7.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0025] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0026] Existing pay-off pulleys with automatic braking functions mostly use mechanical one-way braking devices, such as those that drive brake blocks to clamp the cable using gravity or spring force. However, such solutions have the following drawbacks: Response lag: Mechanical brakes rely on physical contact triggering and are unable to respond to overspeed or reverse motion within milliseconds. Lack of bidirectional control: It can only respond to abnormal movement in one direction and cannot simultaneously prevent the risks of forward overspeed and reverse retraction; Lack of intelligence: lack of real-time monitoring and remote control functions, unable to adapt to dynamic adjustment requirements under complex working conditions; High maintenance cost: Traditional brake components are subject to severe wear and tear, require frequent replacement, and are prone to damage to the cable surface.

[0027] In response to the above problems, there is an urgent need for a wire-laying pulley device that integrates intelligent sensing, two-way braking and remote monitoring functions to improve the safety and reliability of tension wire stringing operations.

[0028] The following is combined with Figures 1 to 8 , an electrically controlled bidirectional braking wire-paying pulley 1 provided in this application is described in detail through specific embodiments and application scenarios.

[0029] Please refer to Figure 1 and Figure 4An embodiment of the present invention provides an electrically controlled bidirectional braking wire-paying pulley 1, comprising a wire-paying pulley body 10, an electrically controlled forward overspeed braking assembly 11, and an electrically controlled reverse overspeed braking assembly 12. The electrically controlled forward overspeed braking assembly 11 and the electrically controlled reverse overspeed braking assembly 12 are respectively arranged on opposite sides of the wire-paying pulley body 10 along the direction of the cable 2; a braking module 13 and a reset assembly 14 are both provided in the electrically controlled forward overspeed braking assembly 11 and the electrically controlled reverse overspeed braking assembly 12, and the braking module 13 is connected to the reset assembly 14. The braking module 13 achieves forward and / or reverse braking of the cable 2 (conductor or ground wire) by clamping the cable 2; the electrically controlled forward overspeed braking assembly 11 and the electrically controlled reverse overspeed braking assembly 12 are both provided with a laser speed sensor 150 and a pressure feedback module 151. The reset assembly 14 receives a signal from the laser speed sensor 150 to trigger the braking operation of the braking module 13. The pressure feedback module 151 is arranged on the braking module 13 and contacts the cable 2 when braking is achieved.

[0030] Specifically, when the laser speed sensor 150 senses an overspeed condition, it immediately sends an electrical signal to the reset component 14 , and the reset component 14 receives the overspeed signal to control the brake module 13 to brake the cable 2 .

[0031] It can be understood that this embodiment can realize intelligent overspeed protection in the bidirectional movement of cable 2, and solve the risk of unidirectional braking failure of traditional pulleys through symmetrically arranged bidirectional braking components; the laser speed sensor 150 monitors the speed of cable 2 in real time. When the transmission speed of cable 2 exceeds the set threshold, the laser speed sensor 150 immediately transmits a signal to the reset component 14, and the reset component 14 triggers the braking module 13 to brake, thereby improving the response accuracy and solving the problem of delayed response of traditional wire-laying pulleys with braking function during braking. The pressure feedback module 151 dynamically monitors the clamping force during braking to avoid overload damage to cable 2, thereby doubly ensuring construction safety.

[0032] Furthermore, a protective cover 110 is provided outside the electronically controlled forward overspeed braking assembly 11 and the electronically controlled reverse braking assembly to protect the internal structure thereof.

[0033] As an optional implementation, in this embodiment, a speed measuring wheel 1112 is further provided in the upper component 111. The speed measuring wheel 1112 abuts against the cable 2 and serves as a compensation device for measuring the speed of the cable 2, thereby further improving the accuracy of the speed measurement.

[0034] Furthermore, a wireless communication module 16 is also provided in the electronically controlled forward overspeed braking component 11 and the electronically controlled reverse overspeed braking component 12. The laser speed sensor 150 and the pressure feedback module 151 are electrically connected to the wireless communication module 16 and the data of the laser speed sensor 150 and the pressure feedback module 151 are transmitted to a remote monitoring terminal (not shown in the figure) through the wireless communication module 16.

[0035] Specifically, the laser speed sensor 150 adopts Doppler laser speed measurement technology, with a sampling frequency of ≥1kHz, and the speed measurement is accurate and stable. Before performing the wire pulling operation, according to the type of cable 2 (conductor wire, ground wire or fiber optic composite ground wire), the adjustment signal is output in reverse through the remote monitoring terminal to set the braking trigger speed threshold.

[0036] It can be understood that by remotely monitoring the braking data through the wireless communication module 16, construction personnel can obtain parameters such as speed and pressure in real time, which facilitates rapid judgment of abnormalities (such as overspeed without triggering braking), greatly reduces the risk of high-altitude inspections, improves fault response efficiency, and significantly improves the real-time and safety of tension line operations.

[0037] Specifically, the operator receives the working data signal of the wireless communication module 16 through the industrial computer on the ground, and obtains parameters such as the cable 2 speed and the brake slider pressure in real time. The working status operation curve can be generated in the industrial computer, and a fault report can be output for possible abnormal working conditions during the wire pulling process, reducing manual troubleshooting work and greatly reducing the risk of high-altitude operation inspections.

[0038] For further information, please refer to Figures 3 to 7 The electric-controlled forward overspeed brake component 11 and the electric-controlled reverse overspeed brake component 12 respectively include a detachably connected upper component 111 and a lower component 112, and the brake module 13 includes an upper brake slider 130 and a lower brake slider 131 respectively arranged on the upper component 111 and the lower component 112, and the upper component 111 and the lower component 112 are also respectively provided with an upper slide rail 1110 and a lower slide rail 1120, and the distance between the upper slide rail 1110 and the lower slide rail 1120 gradually decreases in the direction away from the line-paying pulley body 10, the upper brake slider 130 and the lower brake slider 131 are respectively slidably arranged on the upper slide rail 1110 and the lower rail 1120, and the cable 2 is located between the upper brake slider 130 and the lower brake slider 131.

[0039] It can be understood that the upper / lower split slider design is combined with the gradually narrowing slide rail, so that the slider automatically wedges the cable 2 along the track during braking, producing a self-enhancing effect, significantly improving the braking force reliability; at the same time, the detachable structure facilitates the replacement of worn parts and reduces maintenance costs.

[0040] As an optional embodiment, an elastic clamping layer can be provided on the side of the upper / lower brake slider 131 close to the cable 2 to achieve buffered contact between the brake slider and the cable 2 during braking, thereby protecting the cable 2 from being damaged by friction while ensuring the clamping force of the brake slider on the cable 2.

[0041] Specifically, the upper component 111 and the lower component 112 are installed and fixed by a fixing buckle 113, and the fixing buckle 113 is convenient for disassembly and operation.

[0042] For further information, please refer to Figure 1 and Figure 2 A fixed triangle plate 100 is provided on the main body 10 of the line-paying pulley, and pluggable fixed ear seats 1000 are respectively provided at the opposite ends of the fixed triangle plate 100 to connect the electric-controlled forward overspeed brake component 11 and the electric-controlled reverse overspeed brake component 12.

[0043] It can be understood that the fixed triangle plate 100 and the pluggable ear seat realize modular and rapid disassembly and assembly of the brake assembly, adapt to the replacement needs of different wire diameter working conditions, reduce the equipment idle rate, and significantly improve the adaptability of field construction.

[0044] Specifically, if it is an aerial operation, the line-laying pulley body 10, the electric forward overspeed brake assembly 11 and the electric reverse overspeed brake assembly 12 can be disassembled and transported to the designated work station by aerial operation drones respectively. The installer only needs to install and fasten the corresponding pluggable fixed ear seat 1000 to complete the installation and positioning of the entire system, reducing the transportation weight and transportation volume of a single drone and improving the safety of the overall work.

[0045] Optionally, during ordinary ground wire payout operations, while ensuring safety, the electrically controlled forward overspeed brake assembly 11 and the electrically controlled reverse overspeed brake assembly 12 can be disassembled, and the payout pulley body 10 can be used as an ordinary payout pulley.

[0046] Furthermore, a return coil spring 1111 is provided in the upper component 111, and the return coil spring 1111 is connected to the upper brake slider 130. When braking, the return coil spring 1111 is in a stretched state; after braking, the return coil spring 1111 pulls the upper brake slider 130 to automatically return to the initial position.

[0047] Furthermore, a coil spring group 1121 is also provided in the lower component 112, and the lower brake slider 131 is provided with a connecting plate 1310. The coil spring group 1121 is connected to the connecting plate 1310. When the electrically controlled bidirectional brake line-paying pulley 1 is in the initial state, the coil spring group 1121 is in a stretched state; the lower component 112 is provided with a reset component 14, the reset component 14 includes an electrically controlled ratchet component 140 and a traction rope 141, the electrically controlled ratchet component 140 includes a drive motor 1400 and a ratchet mechanism 1401, the ratchet mechanism 1401 includes a pawl 1402 and a ratchet 1403, the drive motor 1400 controls the pawl 1402 and the drive motor 1400 is electrically connected to the laser speed sensor 150, the electrically controlled ratchet component 140 is coaxially connected to a roller 142, one end of the traction rope 141 is wound around the roller 142, and the other end is connected to the connecting plate 1310.

[0048] It can be understood that through the setting of the spring group 1121 and the reset component 14 in the lower component 112, when braking is required, the electric ratchet component 140 in the reset component 14 receives the electrical signal of the laser speed sensor 150, automatically releases the ratchet to loosen the traction rope 141, and the lower brake slider 131 moves to the braking position on the lower rail 1120 under the tension of the spring group 1121. The entire braking process is fully automatic and does not require human intervention, which reduces the response lag between traditional mechanical structures, makes braking more timely, and significantly reduces the occurrence of safety accidents in tension line operations.

[0049] Specifically, in order to uniformly control and process the data of the laser speed sensor 150, the pressure feedback module 151, the automated operation of the electric-controlled ratchet assembly 140 in the reset assembly 14, and the signal transmission of the wireless communication module 16, the electric-controlled bidirectional braking and line-paying pulley 1 of this embodiment is also integrated with a control assembly (not shown in the figure), and a programmable control board (PLC board) can be provided in the control assembly to realize automated control of the overall system.

[0050] It can be understood that various speed measurement threshold standards are established according to the type of cable 2 and relevant cable operation safety standards, and the cable-speed model is entered into the programmable control board in advance. Before the cable pulling work, the corresponding model is selected on the remote monitoring terminal and then the cable 2 pulling work is started.

[0051] Specifically, according to industry production standards, the embodiment defines a cable speed of >1 km / min as an overspeed and out-of-control speed threshold for all cable types.

[0052] Furthermore, the electric ratchet assembly 140 is also provided with a safety interlock device 143 and a position detection sensor 144. The safety interlock device 143 is connected to the wireless communication module 16 signal. The safety interlock device 143 receives the position detection sensor 144 signal to control the drive motor 1400. When it is detected that the lower brake slider 131 is not fully reset, the pulley is prohibited from entering the next working cycle.

[0053] It can be understood that through the coordinated control of the safety interlock device 143 and the position detection sensor 144, when it is detected that the lower brake slider 131 is not fully reset, the pulley is prohibited from entering the next working cycle, which effectively prevents the risk of misoperation caused by incomplete reset, improves the system safety, and alarms the abnormal state through the wireless module, which complies with safety construction specifications.

[0054] Specifically, the roller 142 is also provided with a rotating motor (not shown in the figure), which receives the electrical signal of the position detection sensor 144 and can rotate the motor to work after braking is completed to control the winding of the traction rope 141, so that the lower brake slider 131 is automatically reset. Optionally, in order to prevent the electronic system from malfunctioning and unable to be completely reset, the electric control ratchet assembly 140 is also installed with a rocker 1404 for manual reset to improve overall stability.

[0055] Furthermore, the lower component 112 is also provided with a synchronous push plate 1311, which is connected and fixed to the lower brake slider 131. A protruding plate 1300 is provided on the side of the upper brake slider 130 close to the lower component 112. When braking, the lower brake slider 131 drives the synchronous push plate 1311 to move, and the synchronous push plate 1311 abuts against the protruding plate 1300 and drives the upper brake slider 130 to move, thereby realizing the coordinated clamping of the upper and lower brake sliders 131 through mechanical linkage.

[0056] It can be understood that the mechanical linkage between the synchronous push plate 1311 and the raised plate 1300 ensures that a single power source drives the dual sliders to move synchronously, eliminating the problem of eccentric wear of the cable 2 caused by asynchronous movement, thereby improving the consistency of the braking effect and extending the service life of the cable 2.

[0057] Specifically, the upper component 111 is further provided with a handle 1113 to facilitate the transportation, disassembly and installation of the electric-controlled forward overspeed brake component 11 or the electric-controlled reverse overspeed brake component 12 .

[0058] It can be understood that the mechanical structure components in the electronically controlled forward overspeed brake component 11 and the electronically controlled reverse overspeed brake component 12 are exactly the same. The difference is that the detection direction of the cable 2 speed is opposite, and the corresponding software of the programmable control board in the control component is different.

When the cable transmission speed exceeds the set threshold, the laser speed sensor immediately transmits a signal to the reset component, and the reset component triggers the brake module to brake, improving the response accuracy and solving the problem of delayed response of the traditional wire-paying pulley with braking function during braking. The pressure feedback module dynamically monitors the clamping force during braking to avoid overload damage to the cable, doubly ensuring construction safety.
