Description

Technical Field

[0001] This invention relates to the field of construction and maintenance equipment technology, and in particular to a multi-source sensing dynamic protection electric conveyor system for all-terrain mechanized construction and maintenance. Background Technology

[0002] In scenarios such as high-altitude construction, maintenance, evacuation, and emergency rescue in power distribution networks, electric conveyor systems have become key equipment. Their basic principle is to use a built-in power mechanism to drive friction wheels to clamp ropes, enabling the device to autonomously crawl along the ropes, thus carrying personnel or heavy objects quickly to high-altitude work sites. These devices are typically used in conjunction with drones to drop traction ropes. By setting fixed anchor points on the ground and attaching points on high-altitude towers, a vertical or inclined transport channel is constructed, greatly improving the efficiency of power grid construction and rescue.

[0003] Specifically, existing technologies, such as the rope-climbing robot disclosed in Chinese Patent Publication No. CN108217544A, include a battery pack, motor, reducer, drive wheel, main frame, and tension chain. The battery pack, motor, reducer, and drive wheel are sequentially connected to provide driving force. The tension chain is mounted on the main frame and partially surrounds the drive wheel, using pins on the drive wheel to clamp the lifting rope. The combined friction between the two enables load-bearing climbing, theoretically capable of lifting 250-300 kg. However, while this type of device provides a feasible solution in terms of power transmission and overall frame, it still has significant shortcomings in specific safety protection and adaptability design.

[0004] In summary, existing rope climbing devices generally suffer from three significant defects: First, they mostly use smooth-surfaced drive wheels or simple pin structures, resulting in insufficient engagement between the wheel and the rope, making them prone to slippage and loosening under high loads or when the rope surface is wet. Second, they lack effective anti-reverse mechanisms, failing to effectively lock the rope when the device stops operating or encounters a sudden power outage, easily leading to backward slippage under heavy loads and posing a serious safety hazard. Third, they lack emergency unlocking mechanisms; if the rope becomes worn, punctured, or has foreign objects stuck, causing the mechanism to lock, workers at height will face the risk of being unable to descend or evacuate, making it difficult to meet the requirements of mechanized construction in complex power grid environments. Summary of the Invention

[0005] In order to address the technical deficiencies mentioned in the background section, the present invention aims to provide a multi-source sensing dynamic protection electric conveyor system for all-terrain mechanized construction and maintenance, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-source sensing dynamic protection electric conveyor system for all-terrain mechanized construction and maintenance includes: A housing, wherein the housing is provided with a rope inlet and a rope outlet; The driving mechanism includes a driver fixed on the housing and a drive rope wheel connected to the output shaft of the driver. The drive rope wheel has a number of protruding teeth spaced apart on its outer circumference. The anti-reverse mechanism includes a lower support block that can be movably disposed within the housing, a support plate disposed within the housing, and an elastic element connecting the support plate and the lower support block. A lower compression channel is formed between the lower support block and the drive rope wheel. The top surface of the lower support block is inclined upward from left to right and has a ratchet at its end. The ratchet is located on the side of the rope outlet. An emergency unlocking mechanism includes a threaded sleeve fixed to the plate and a screw threadedly connected to the threaded sleeve. The lower end of the screw extends out of the housing and is connected to a rotating handle. A rope is threaded inside the housing, entering through the rope inlet, passing through the lower compression channel, and exiting through the rope outlet.

[0007] Specifically, it also includes a locking clamping mechanism, which includes: A left limiting block and a right limiting block are provided. The left limiting block and the drive rope wheel form a left limiting channel, and the right limiting block and the drive rope wheel form a right limiting channel. The upper end of the left limiting block is rotatably engaged with the housing through a left rotating shaft, and the lower end is provided with a left arc-shaped groove. The upper end of the right limiting block is rotatably engaged with the housing through a right rotating shaft, and the lower end is provided with a right arc-shaped groove. The left and right pushers are fixed inside the housing and are used to push the lower ends of the left and right limit blocks respectively to adjust the gap between the lower parts of the left and right limit channels.

[0008] Specifically, guide slopes are formed on the two inner sides of the left limiting block and the right limiting block, and the two guide slopes form a figure-eight structure; The left and right sides of the lower support block are respectively formed with matching inclined surfaces that slide with the guide inclined surface; When the left and right limiting blocks swing inward and clamp together, the lower support block is driven to retract downward through the cooperation of the guide ramp.

[0009] Specifically, a left limiting post and a right limiting post are fixed inside the housing. The left limiting post extends into the left arc-shaped groove, and the right limiting post extends into the right arc-shaped groove.

[0010] Specifically, both the left pusher and the right pusher are electric push rods.

[0011] Specifically, a guide channel is provided on the inner side of the housing, and the guide channel is located between the rope inlet and the left limiting channel; A speed sensor for detecting rope speed is provided on one side of the guide channel; When the speed sensor detects that the rope speed exceeds a preset threshold, the left and right pushers of the locking clamping mechanism are activated, driving the left and right limit blocks to swing inward to lock the rope.

[0012] Specifically, it also includes a rope-feeding mechanism, which includes two fixed shafts, bearings sleeved on the fixed shafts, and guide wheels sleeved on the outside of the bearings, with a rope-feeding gap formed between the two guide wheels for the rope to pass through.

[0013] Specifically, the outer surface of the housing is provided with a hook, a handle, and a display panel, and the handle is provided with control buttons.

[0014] Specifically, the housing contains a battery and a control circuit board, and the driver, left pusher, right pusher, speed sensor and control button are all electrically connected to the control circuit board.

[0015] Specifically, the elastic element is a spring, a sheet, or a rubber pad.

[0016] Beneficial effects: This application achieves mechanization and intelligence in high-altitude power grid operations by integrating a drive mechanism, an anti-reverse mechanism, an emergency unlocking mechanism, and a locking clamping mechanism. The convex teeth on the outer circumference of the drive rope wheel compress the rope, significantly improving grip and anti-slip performance. The anti-reverse mechanism uses ratchet unidirectional locking to effectively prevent retraction during power outages. The emergency unlocking mechanism forcibly releases the ratchet lock through helical transmission, ensuring safe evacuation under extreme conditions. The locking clamping mechanism monitors speed and triggers locking within milliseconds in case of overspeed, creating multiple safety barriers. The coordinated operation of these mechanisms solves the problems of existing devices, such as easy slippage, lack of anti-reverse mechanisms, and difficulty in emergency response, and provides high load capacity, high safety, and all-terrain adaptability.

[0022] Please refer to the attached document. Figures 1-13 : This embodiment discloses a multi-source sensing dynamic protection electric conveyor system for all-terrain mechanized construction and maintenance, including a housing 10, a drive mechanism 20, an anti-retreat mechanism 30, an emergency unlocking mechanism 40, and a rope 50 passing through the housing 10. The housing 10 has a rope inlet 11 and a rope outlet 12. The rope 50 enters through the rope inlet 11, passes through a lower compression channel, and extends out through the rope outlet 12. This embodiment, through an integrated housing design, modularly integrates core functions such as drive, anti-retreat, emergency unlocking, and locking clamping, making the overall structure of the device compact and the center of gravity stable. It can adapt to the needs of high-altitude construction, maintenance, and rescue in various complex terrains such as iron towers, deep wells, and crossings, realizing the mechanization and intelligent upgrading of power grid construction.

[0023] like Figure 3 As shown, the drive mechanism 20 includes a driver 21 fixed on the housing 10 and a drive rope wheel 22 connected to the output shaft of the driver 21. The drive rope wheel 22 has several teeth 221 spaced apart on its outer circumference. The driver 21 is preferably a high-torque geared motor, capable of providing continuous and stable output power to meet the needs of heavy-load lifting. When the drive rope wheel 22 rotates and compresses the rope 50, the teeth 221 compress the rope 50, forcing it to undergo local deformation. This significantly increases the interlocking force and friction between the wheel and the rope, effectively preventing slippage and loosening caused by load changes or wet rope surfaces during high-altitude construction and maintenance, greatly improving the safety and reliability of climbing.

[0024] like Figure 3As shown, the anti-reverse mechanism 30 includes a lower support block 31 movably disposed within the housing 10, a support plate 32 disposed within the housing 10, and an elastic member 33 connecting the support plate 32 and the lower support block 31. A lower compression channel is formed between the lower support block 31 and the drive rope wheel 22. The top surface of the lower support block 31 slopes upward from left to right. Figure 6 As shown, a height difference h is formed between the lower left side and the higher right side, where h > 0. The lower support block 31 has a ratchet 311 at its upward-sloping end, located on the side of the rope outlet 12. This anti-reverse mechanism 30 utilizes the inclined plane self-locking principle. Under normal operating conditions, the elastic element 33 pushes the support plate 32 and the lower support block 31 upwards, causing the ratchet 311 to tightly fit the rope 50. Due to the unidirectional guiding effect of the ratchet 311, the rope 50 can smoothly pass from left to right (i.e., from the rope inlet 11 to the rope outlet 12), but otherwise it will be jammed by the ratchet 311. Thus, when the driver 21 stops working or encounters a power outage, it can effectively lock the position of the rope 50, preventing the device from sliding back along the rope 50 and eliminating the safety hazards of high-altitude construction and maintenance.

[0025] like Figure 3 As shown, the emergency unlocking mechanism 40 includes a threaded sleeve 41 fixed to the support plate 32 and a screw 42 threadedly connected to the threaded sleeve 41. The lower end of the screw 42 extends out of the housing 10 and is connected to a rotating handle 43. When the rope 50 is worn, punctured, or jammed by foreign objects, preventing the ratchet 311 from releasing normally, or when the device needs to be lowered urgently, the operator can manually rotate the rotating handle 43. Through the helical transmission between the screw 42 and the threaded sleeve 41, the support plate 32 and the lower support block 31 of the entire anti-reverse mechanism 30 are forced to move downward as a whole. This instantly increases the vertical space of the lower compression channel and disengages the ratchet 311 from the rope 50, releasing the locked state and ensuring that construction personnel can safely evacuate or be lowered in any emergency.

[0026] like Figure 4As shown, the multi-source sensing dynamic protection electric conveying system 1 of this embodiment also includes a locking clamping mechanism 60, which includes a left limiting block 61, a right limiting block 62, a left rotating shaft 63, a right rotating shaft 64, a left pusher 65, and a right pusher 66; a left limiting channel is formed between the left limiting block 61 and the drive rope wheel 22, and a right limiting channel is formed between the right limiting block 62 and the drive rope wheel 22; the upper end of the left limiting block 61 is rotatably engaged with the housing 10 through the left rotating shaft 63, and the lower end is provided with a left arc-shaped groove 611; the upper end of the right limiting block 62 is rotatably engaged with the housing 10 through the right rotating shaft 64, and the lower end is provided with a right arc-shaped groove 621; a left limiting post 67 and a right limiting post 68 are also fixed inside the housing 10, with the left limiting post 67 extending into the left arc-shaped groove 611 and the right limiting post 68 extending into the right arc-shaped groove 621. The locking clamping mechanism 60 forms the last line of defense for the device, and its dual-block symmetrical design can apply force evenly. The left limit block 61 and the right limit block 62 adopt a lever structure with the upper end rotating and the lower end swinging. Compared with the linear translation structure, it can obtain a larger clamping stroke and clamping force with less driving force, ensuring rapid stopping in emergency situations.

[0027] like Figure 7 As shown, the left pusher 65 and the right pusher 66 are fixed inside the housing 10, respectively, and are used to push the lower ends of the left limiting block 61 and the right limiting block 62 to adjust the gap between the lower parts of the left limiting channel and the right limiting channel. During operation, the left pusher 65 and the right pusher 66 extend outward synchronously, pushing the lower ends of the left limiting block 61 and the right limiting block 62 to swing inward around their respective axes of rotation, thereby reducing the channel spacing and achieving a rigid lock on the rope 50.

[0028] In a preferred embodiment, both the left pusher 65 and the right pusher 66 are electric actuators. Using electric actuators as a power source has the advantages of simple structure, controllable thrust, and easy integration with the control system. It can precisely control the extension and speed of the actuators through circuitry, thereby achieving accurate triggering and smooth transition of the locking action.

[0029] like Figure 7As shown, guide ramps 612 are formed on the two inner surfaces of the left limiting block 61 and the right limiting block 62, forming a figure-eight structure. The left and right sides of the lower support block 31 have corresponding mating ramps 312 that slide in conjunction with the guide ramps 612. When the left limiting block 61 and the right limiting block 62 swing inwards to clamp, the lower support block 31 is driven to retract downwards through the cooperation of the guide ramps 612. The figure-eight guide structure solves the interference problem between the locking action and the anti-retraction function. When the locking clamping mechanism 60 is activated, the guide ramps 612 forcefully press down on the mating ramps 312, causing the lower support block 31 to overcome the elastic force of the elastic element 33 and retract downwards, automatically creating the space required for locking and preventing mechanical jamming. Conversely, when the lower support block 31 is forced to move downwards during emergency unlocking, it will not hinder the normal reset of the left limiting block 61 and the right limiting block 62, ensuring the spatial independence and operational coordination of the two mechanisms.

[0030] like Figure 4 As shown, a left limiting post 67 and a right limiting post 68 are also fixed inside the housing 10. The left limiting post 67 extends into the left arc-shaped groove 611, and the right limiting post 68 extends into the right arc-shaped groove 621. The cooperation of the left limiting post 67 and the left arc-shaped groove 611, and the right limiting post 68 and the right arc-shaped groove 621, constitutes a mechanical hard limiting structure, which can precisely limit the swing angle range of the left limiting block 61 and the right limiting block 62, preventing them from swinging excessively under the action of the return spring or inertial force, and ensuring the stability of the structure and the consistency of the action of the device under repeated start-stop and long-term vibration environment.

[0031] like Figure 4 As shown, a guide channel 13 is provided inside the housing 10, located between the rope inlet 11 and the left limiting channel. A speed sensor 19 for detecting the speed of the rope 50 is provided on one side of the guide channel 13. When the speed sensor 19 detects that the speed of the rope 50 exceeds a preset threshold, the left pusher 65 and the right pusher 66 of the clamping mechanism 60 are activated, driving the left limiting block 61 and the right limiting block 62 to swing inward to clamp the rope 50. The guide channel 13 plays a role in regulating the direction of rope entry, preventing the rope 50 from swaying and tangling before entering the complex mechanism. The speed sensor 19 is preferably a Hall sensor or a photoelectric encoder. Its detection principle is to calculate the real-time linear speed of the rope 50 by sensing the pulse signal generated by the braided texture or preset magnetic mark on the surface of the rope 50 and calculating the rate of change of pulse frequency per unit time. For example, when the device is operating normally, the speed of the rope 50 is maintained at 0.5m / s. If the speed suddenly rises to 2m / s (exceeding the preset threshold) due to rope 50 breakage or drive failure, the control system will determine that it is in a stall state within milliseconds and immediately trigger the locking clamping mechanism 60 to achieve passive safety protection of locking upon stall, effectively avoiding high-altitude fall accidents.

[0032] like Figure 4 As shown, the multi-source sensing dynamic protection electric conveying system 1 of this embodiment also includes a rope-feeding mechanism 70. The rope-feeding mechanism includes two fixed shafts 71, bearings 72 sleeved on the fixed shafts 71, and guide wheels 73 sleeved on the outside of the bearings 72. A rope-feeding gap is formed between the two guide wheels 73 for the rope 50 to pass through. The rope 50 first enters the housing 10 through the rope-feeding gap, then enters the left limiting channel along the guide channel 13, and then passes through the lower compression channel and the right limiting channel before extending out from the rope outlet 12. By setting the freely rotatable guide wheels 73, the rope-feeding mechanism 70 transforms the sliding friction between the rope 50 and the fixed components into rolling friction, which greatly reduces the rope-feeding resistance and the wear rate of the rope 50. At the same time, the V-shaped or parallel gap formed by the two guide wheels 73 can adaptively center ropes 50 of different diameters, ensuring the smoothness of rope feeding and the reliability of long-term use.

[0033] like Figure 1 As shown, the exterior of the housing 10 is equipped with a hook 14, a handle 15, and a display panel 16. The handle 15 has a control button 17, which is used to control the start and stop of the driver 21. The hook 14 is used to connect the operator's safety harness or fixing device, and its exposed design facilitates quick hooking and unhooking. The handle 15 is ergonomically designed, allowing the operator to hold it firmly while working at heights and assisting in maintaining balance. The display panel 16 is used to display the power level, operating status, and fault codes in real time, giving the operator a clear understanding of the device's operating condition. The control button 17 provides an intuitive local control interface, enabling convenient one-button start and stop operation.

[0034] like Figure 4 As shown, the housing 10 houses a battery 18 and a control circuit board. The driver 21, left actuator 65, right actuator 66, speed sensor 19, and control button 17 are all electrically connected to the control circuit board. The battery 18 provides an independent DC power supply for the entire device, eliminating reliance on external cables and giving the device strong mobility and all-terrain adaptability. The control circuit board is responsible for receiving signals from the speed sensor 19, processing commands from the control button 17, and coordinating the collaborative work of the driver 21 and the locking clamping mechanism 60, realizing mechatronic intelligent control.

[0035] In a preferred embodiment, the elastic element 33 is a spring. In other embodiments, the elastic element 33 can also be a sheet, a rubber pad, etc. Using a spring as the elastic element 33 has the characteristics of good linear stiffness, long fatigue life, and strong environmental adaptability. It can maintain a stable elastic restoring force in a wide temperature range and high humidity environment, ensuring that the anti-recoil mechanism 30 can operate reliably under various harsh climatic conditions.

[0036] like Figure 9As shown, the multi-source sensing dynamic protection electric conveyor system 1 of this embodiment can be applied to high-altitude operations on iron towers. The figure shows two ways to lift workers using the multi-source sensing dynamic protection electric conveyor system 1. In the lifting method on the left, a hanging point 82 is first set on the iron tower 81. The upper end of the rope 50 is connected to the hanging point 82, and the lower end of the rope 50 hangs down to the ground. The lower end of the rope 50 enters from the rope inlet 11, passes through the lower compression channel, and extends out from the rope outlet 12. The multi-source sensing dynamic protection electric conveyor system 1 is connected to the hook of the operator's high-altitude work safety suit through the hook 14 on the surface of its shell 10. When the multi-source sensing dynamic protection electric conveyor system 1 is started, it crawls along the rope 50, thereby lifting the worker from the ground to the high altitude. In addition, to improve safety, a hanging point 82 can be added to the iron tower 81. This hanging point 82 is used to attach a safety rope 89. The safety rope 89 is also connected to the hook on the back of the operator's high-altitude work safety suit, forming a "main and backup double insurance" fall prevention system. This method is suitable for vertical tower climbing operations on newly built lines or towers without elevators. Compared with traditional manual climbing, it is several times more efficient and greatly reduces labor intensity.

[0037] The lifting method shown on the right side of the diagram involves setting up an attachment point 82 on the tower 81, with a pulley 83 at the attachment point 82. A rope 50 is looped around the pulley 83, with one end of the rope 50 connected to the worker's high-altitude work safety suit. The other end of the rope 50 enters through the rope inlet 11, passes through the lower compression channel, and extends from the rope outlet 12. The multi-source sensing dynamic protection electric conveyor system 1 is fixed to the bottom of the tower 81 via hooks 14 on its housing 10. Activating the multi-source sensing dynamic protection electric conveyor system 1 raises the worker's height by pulling the rope 50. This winch-type application utilizes the device's strong pulling force, changing the direction of the force through the fixed pulley 83. It is particularly suitable for single-person lifting operations in special conditions where the tower is narrow or where fixed guide rails cannot be installed.

[0038] like Figure 10As shown, the multi-source sensing dynamic protective electric conveyor system 1 in this embodiment is also applied to high-altitude tower operations. First, a hanging point 82 is set on the tower 81. The upper end of the rope 50 is connected to the hanging point 82, and the lower end of the rope 50 hangs down to the ground. The lower end of the rope 50 enters from the rope inlet 11, passes through the lower compression channel, and extends from the rope outlet 12. Then, the lower end of the rope 50 is connected to the fixed anchor point 84 on the ground, forming an inclined structure. The multi-source sensing dynamic protective electric conveyor system 1 is connected to the hook of the operator's high-altitude work safety suit through the hook 14 on the surface of its shell 10. When the multi-source sensing dynamic protective electric conveyor system 1 is started, it crawls along the inclined rope 50, thereby lifting the operator from the ground to the high altitude. In addition, to improve safety, a hanging point 82 can be added to the tower 81. This hanging point 82 is used to attach a safety rope 89, which is also connected to the hook on the back of the operator's high-altitude work safety suit to improve safety. This application scenario demonstrates the device's all-terrain adaptability. In inclined span construction across valleys or rivers, the device can overcome the component of gravity and climb stably along the cableway, solving the problem that traditional lifting equipment cannot work on inclined ropes.

[0039] like Figure 11 As shown, the multi-source sensing dynamic protective electric conveyor system 1 of this embodiment can be applied in a lateral conveying scenario. First, hangers 82 are set on two iron towers 81 respectively. One end of the rope 50 enters from the rope inlet 11, passes through the lower compression channel, and extends from the rope outlet 12. One end of the rope 50 is connected to the hanger 82 on the left iron tower 81, and the other end of the rope 50 is connected to the hanger 82 on the right iron tower 81. The ropes 50 form a parallel structure. The multi-source sensing dynamic protective electric conveyor system 1 is connected to the hook of the operator's high-altitude work safety suit through the hook 14 on the surface of its shell 10. When the multi-source sensing dynamic protective electric conveyor system 1 is started, it crawls along the parallel ropes 50, thereby transporting the operator from one side to the other. In addition, to improve safety, hangers 82 can be added on the two iron towers 81. These hangers 82 are used to attach safety ropes 89, which are also connected to the hooks on the back of the operator's high-altitude work safety suit to improve safety. This horizontal crossing function is particularly important in the maintenance of transmission lines. When workers need to move from one tower to another and there is no foothold in between, this device provides a safe and quick aerial transfer route.

[0040] like Figure 12As shown, the multi-source sensing dynamic protection electric conveying system 1 of this embodiment can be applied in heavy object lifting scenarios. First, a pulley 83 is installed on the suspension 86 of the upright 85. A rope 50 is then passed around the pulley 83, with one end of the rope 50 connected to the heavy object 87. The other end of the rope 50 enters through the rope inlet 11, passes through the lower compression channel, and extends from the rope outlet 12. The multi-source sensing dynamic protection electric conveying system 1 is fixed to the bottom of the upright 85 via hooks 14 on the surface of its housing 10. After starting the multi-source sensing dynamic protection electric conveying system 1, the height of the heavy object 87 is raised by pulling the rope 50. This indicates that the device can not only be used for carrying people but also as a light lifting device, easily lifting insulator strings, hardware, and other construction materials, achieving multi-purpose functionality and significantly reducing the investment in lifting equipment at the construction site.

[0041] like Figure 13 As shown, the multi-source sensing dynamic protective electric conveyor system 1 of this embodiment can be applied in deep well rescue scenarios. First, an attachment point 82 is set on the crossbar 88. The upper end of the rope 50 is connected to the attachment point 82, and the lower end of the rope 50 hangs down to the bottom of the deep well. Rescuers, carrying the multi-source sensing dynamic protective electric conveyor system 1, descend to the bottom of the deep well via a safety rope 89. The lower end of the rope 50 enters through the rope inlet 11, passes through the lower compression channel, and extends out through the rope outlet 12. The multi-source sensing dynamic protective electric conveyor system 1 is connected to the hook 14 on the surface of its shell 10 to the hook of the operator's high-altitude work safety suit. When the multi-source sensing dynamic protective electric conveyor system 1 is activated, it crawls along the rope 50, thereby lifting the rescuer and the trapped person to the ground. In rescue operations in confined spaces such as deep wells and vertical shafts, this device demonstrates extremely high practical value. Its self-powered and fall-prevention protection functions allow rescuers to autonomously complete the weighted ascent without relying on an external winch, greatly shortening the golden rescue time.
