Description
Technical Field
[0001] The present invention relates to the field of devices for electric power construction, and in particular to a multifunctional protection device and method for electric power construction. Background Art
[0002] Power construction is a crucial component of power system construction and maintenance, involving numerous high-altitude operations, such as transmission line installation and substation equipment installation and maintenance. Therefore, in these operations, lifting devices (such as aerial work vehicles and lifting platforms) serve as key maintenance equipment, transporting construction personnel and tools to the designated heights to improve operational efficiency and safety. However, the functionality of a lifting device must not only be reflected in its lifting capacity, but also in its stability, ease of operation, and safety features to ensure a smooth construction process.
[0003] At present, the safety protection of lifting devices mainly relies on workers wearing safety ropes and connecting them to the equipment to prevent high-altitude fall accidents. Although this method can prevent workers from falling directly to a certain extent, once an accident occurs and the workers are left hanging in the air, rescue must be carried out immediately, which not only wastes time and affects the construction progress, but may also cause secondary injuries due to untimely rescue. In addition, the safety rope restricts the workers' range of movement, and prolonged hanging state will cause great discomfort and may even cause health risks due to poor blood circulation. In other words, traditional safety protection methods lack active protection mechanisms and cannot provide more comprehensive safety guarantees in the event of equipment failure or emergencies.

Through the synergistic effects of real-time monitoring, rapid response, and intelligent adjustment, it provides a more reliable safety measure for high-altitude electrical construction, thereby improving construction safety and work efficiency. The present invention utilizes a buffer frame to prevent workers from climbing over the fence due to inertia, further enhancing the anti-tip protection for workers and providing a more reliable safety measure for high-altitude electrical work. The buffer frame relies on the automatic response of its mechanical structure to achieve its function, offering the technical advantages of rapid response and stable performance. The present invention utilizes a locking assembly and a first transmission assembly that automatically releases the locking assembly's restraining state in critical situations. This structural stability during daily use provides the buffer frame with the necessary structural freedom in emergency situations, achieving an organic combination of stability and safety. The first transmission assembly automatically coordinates the operating state of the fence and buffer frame with the safety lock state, ensuring that the present invention can automatically and quickly respond when performing safety protection actions and automatically lock when returning to normal, thereby improving the ease of use of the present invention. The present invention uses a controller, a top foot and a stabilizing component to enhance the stability of the present invention, reduce the risk of tipping due to uneven ground, load changes and increased center of gravity, and further improve the safety of the present invention.

DETAILED DESCRIPTION
[0030] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.
[0031] Embodiment: A multifunctional protection device for electric power construction, as shown in Figure 1, includes: a power support base 101, a lifting frame 102 fixedly mounted on the power support base 101, a base plate 103 fixedly mounted on the top of the lifting frame 102, and a fence 104 set on the base plate 103; the power support base 101 is composed of a control system, a drive system and a mobile system, and the drive system and the mobile system realize the free displacement of the power support base 101; the height of the base plate 103 is controlled by the telescopic movement of the lifting frame 102; the fence 104 maintains the surroundings of the base plate 103, and workers will safely carry out electric power construction within the fence 104.
[0032] Combine Figure 2 As shown, the lifting frame 102 includes: scissor plates 1021, connecting shafts 1022 rotatably mounted between the scissor plates 1021, a first fixed support plate 1023 fixedly mounted on the base plate 103 and the power bearing seat 101, a guide rod 1024 fixedly mounted on the base plate 103 and the power bearing seat 101, a servo motor 1025 fixedly mounted on one of the connecting shafts 1022, and a control rod 1026 disposed between the connecting shafts 1022; Among them, the scissor plate 1021 is composed of two cross-hinged long plates, and the front and rear scissor plates 1021 form a scissor unit; the lifting frame 102 is composed of symmetrically arranged left and right vertical columns of scissor units, and two groups of scissor units in each vertical column, totaling four groups of scissor units. The two adjacent groups of scissor units in the same vertical column are linked by end hinges. Specifically, for example, the lower left end of the scissor unit above the left vertical column is hinged to the upper left end of the scissor unit below the left vertical column, and the lower right end of the scissor unit above the left vertical column is hinged to the upper right end of the scissor unit below the left vertical column. Each scissor unit is equipped with four connecting shafts 1022, which are located at the four rotational connections of the front and rear scissor plates 1021. The hinged ends of adjacent scissor units share the connecting shaft 1022. For example, in the four scissor units in the left and right vertical columns, the eight ends between the two lower scissor units and the two upper scissor units will share four connecting shafts 1022. The first fixed support plate 1023 is arranged at the bottom of the base plate 103 and the top of the power support base 101. In the two vertical rows of scissor lift units, the ends located at the outermost four corners are rotatably connected to the first fixed support plate 1023. Specifically, the upper left end of the scissor lift unit above the left vertical row and the upper right end of the scissor lift unit above the right vertical row are rotatably connected to the first fixed support plate 1023 at the bottom of the base plate 103, and the lower left end of the scissor lift unit below the left vertical row and the lower right end of the scissor lift unit below the right vertical row are rotatably connected to the first fixed support plate 1023 at the top of the power support base 101. The guide rod 1024 is provided at the bottom of the base plate 103 and the top of the power bearing seat 101, wherein the connecting shaft 1022 at the uppermost layer is slidably connected to the guide rod 1024 at the bottom of the base plate 103, and the connecting shaft 1022 at the lowermost layer is slidably connected to the guide rod 1024 at the top of the power bearing seat 101. In this embodiment, in order to avoid interference between the arrangement positions of the connecting shaft 1022 and the guide rod 1024, the end of the scissor unit connected to the first fixed support plate 1023 is not provided with a connecting shaft 1022, that is, only two connecting shafts 1022 are provided on the uppermost layer and the lowermost layer. The control rod 1026 is arranged between the four connecting shafts 1022 on the same layer. The control rod 1026 is provided with two sections of threads with opposite rotation directions (not shown in the drawings). The control rod 1026 is rotatably connected to the two connecting shafts 1022 on the outside of the four connecting shafts 1022 on this layer, and forms a threaded matching relationship with the two connecting shafts 1022 in the middle position through the above two sections of threads. When the control rod 1026 rotates, it will be able to control the two connecting shafts 1022 in the middle position to achieve synchronous and reverse movement, thereby controlling the two vertical rows of scissors fork units to extend or retract; the servo motor 1025 is fixedly installed on one of the connecting shafts 1022 in the outer position of a layer of connecting shafts 1022 connected to the control rod 1026, specifically on the connecting shaft 1022 on the left side. The output end of the servo motor 1025 is fixedly connected to the control rod 1026 through a coupling, thereby driving the control rod 1026 to rotate.
[0033] Start the servo motor 1025 and drive the joystick 1026 to rotate, thereby controlling the movement of the two connecting shafts 1022 in the middle position connected to it. The relative displacement of the connecting shafts 1022 will control the left and right vertical scissor units to extend or retract synchronously, thereby realizing the vertical displacement of the base plate 103, so that the device can meet different construction height requirements.
[0034] Combine Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the device further includes: a protection assembly disposed between the base plate 103 and the fence 104, the protection assembly being used to provide safety for workers, and the protection assembly including: a sensor 201 fixedly mounted on the fence 104, a support plate 202 rotatably mounted at the lower portion of the fence 104, an electric push rod 203 disposed on the base plate 103, a control block 204 fixedly mounted on the telescopic end of the electric push rod 203, a sliding block 205 slidably mounted on the control block 204, and a hinge rod 206 fixedly mounted on the support plate 202; Since there is a clear difference between the force exerted when a person actively leans against the fence 104 and the force exerted when accidentally falling on the fence 104, which is reflected in the rate of change of force and the peak force, when actively leaning, the rate of change of force is low, and when accidentally falling and colliding, the rate of change of force is high; when actively leaning, the peak force accounts for about 30% of the body weight, and the force exerted when accidentally falling also includes the kinetic energy conversion of the body falling, so the peak force may reach several times the body weight. Therefore, the sensor 201 is used to sense the magnitude of the force exerted on the fence 104. The sensor 201 is connected to the control system in the power support seat 101 through an electrical signal. The control system determines whether the worker has a gravity imbalance condition based on the feedback data. If the rate of change of the force is low and the peak value is low, it can be determined as a normal leaning condition. If the rate of change of the force is high and the peak value is high, it can be determined as an accidental fall condition; support plate 2 02 is provided with four pieces. When the four support plates 202 are in a horizontal state, they can jointly form a stable working support surface for use. When the four support plates 202 rotate downward, the height of the support surface will decrease accordingly; there are four sliding blocks 205, which are respectively corresponding to the four support plates 202; one side of the support plate 202 is rotatably connected to the fence 104, and the other side of each support plate 202 is fixedly connected to a hinge rod 206; the four hinge rods 206 are rotatably connected to the four sliding blocks 205 respectively, thereby realizing the movable connection between the four support plates 202 and the control block 204. When the electric push rod 203 drives the control block 204 to move up and down, it can control the four support plates 202 to rotate synchronously in the upward and downward directions, that is, to realize the switching of the height position of the support surface constituted by the support plates 202; the electric push rod 203 is connected to the control system through electrical signals.
[0035] When a worker accidentally hits the fence 104 during construction and is in danger of falling, the sensor 201 detects the force and immediately transmits an electrical signal to the control system. Based on a preset judgment standard, if the control system determines that the situation has reached the accident standard, it immediately drives the electric push rod 203 to operate. The operation of the electric push rod 203 drives the control block 204 to move, causing the support surface height of the support plate 202 to rapidly decrease, thereby effectively lowering the worker's support center of gravity. At the same time, the inclined surface created by the lowering height of the support plate 202 can guide the worker's body diagonally, helping him to better return to the interior space of the fence 104, effectively preventing the worker from falling from the device. When the danger is eliminated, the electric push rod 203 is manipulated to move the control block 204 upward to restore the support surface to its original height, allowing the worker to quickly return to normal working conditions and continue electrical construction. Compared with existing technologies, the present device provides a more reliable safety guarantee through the synergistic effect of real-time monitoring, rapid response, and intelligent adjustment, thereby improving the safety and work efficiency of the device during high-altitude electrical construction.
[0036] Combine Figure 6 and Figure 7 As shown, the device also includes: a mounting platform 301 fixedly mounted on the base plate 103, and a buffer rack 302 arranged on the mounting platform 301; the middle part of the mounting platform 301 is hollow, and the electric push rod 203 is arranged in the middle part of the mounting platform 301; the buffer rack 302 is arranged between the mounting platform 301 and the electric push rod 203, and between the fence 104 and the mounting platform 301, so that the electric push rod 203 can be movably mounted on the mounting platform 301 through the buffer rack 302, and the fence 104 can be movably mounted on the base plate 103, four groups of buffer racks 302 are provided between the mounting platform 301 and the fence 104 on each side, and two groups of buffer racks 302 are provided on each side of the mounting platform 301 and the electric push rod 203.
[0037] The buffer frame 302 includes: a second fixed support plate 3021, a first telescopic branch rod 3022 and a second telescopic branch rod 3023 rotatably mounted between the second fixed support plate 3021, and a first return spring 3024 fixedly mounted between the first telescopic branch rod 3022 and the second telescopic branch rod 3023; the second fixed support plate 3021 is fixedly mounted on the mounting platform 301, on the inner wall of the fence 104 and on the outer wall of the electric push rod 203; the first telescopic branch rod 3022 and the second telescopic branch rod 3023 are slidably matched, the first telescopic branch rod 3022 is rotatably connected to the second fixed support plate 3021 on the mounting platform 301, and the second telescopic branch rod 3023 is rotatably connected to the second fixed support plate 3021 on the fence 104 or the electric push rod 203.
[0038] When a worker collides with the fence 104, the fence 104 and the protective components thereon will be displaced relative to the base plate 103. Specifically, the fence 104 and the electric push rod 203 connected thereto will cause each buffer frame 302 to deform, the first telescopic branch rod 3022 and the second telescopic branch rod 3023 to slide relative to each other, and the first return spring 3024 will be deformed accordingly. Based on the elastic recovery characteristics of the first return spring 3024, the recovery trend of the first return spring 3024 will apply a force opposite to the direction of impact to the worker through the fence 104. The reverse force can effectively offset the instantaneous impact force received by the worker, preventing the worker from climbing over the fence 104 under the action of inertia, further improving the anti-rollover protection effect of the device on the worker, and providing more reliable safety protection for high-altitude power operations. The use of the buffer frame 302 relies on the automatic response of the mechanical structure, and has the technical advantages of rapid response and stable effect.

[0041] When the sensor 201 detects an abnormal impact and triggers the support plate 202 to rotate downward to achieve real-time protection for the worker, the support plate 202 rotates and drives the third fixed support plate 408 to move downward, and the rotating frame 405 is controlled to rotate. The connecting rod 406 connected to its end then lifts the plug block 403, and the plug block 403 is quickly pulled out of the socket 401, immediately releasing the fixed connection between the fence 104 and the bottom plate 103, so that the buffer frame 302 immediately enters the working state; when the dangerous state is lifted and the worker resumes work after confirming his own state, the buffer frame 302 restores the normal relative position between the fence 104 and the bottom plate 103, and then controls the support plate 202 to rotate upward and return to its original position. At this time, the third fixed support plate 408 is driven to move upward, and with the restoring effect of the second return spring 407, the rotating frame 405 will be reversed and returned to its original position, and the plug block 403 is reinserted into the socket 401 to achieve automatic locking of the fence 104.

[0044] After the device is moved to the construction area, the controller 501 is started to control the top foot 502 to extend; when a top foot 502 contacts the ground and reaches the preset pressure threshold, the pressure sensor on it immediately feeds back a signal to the controller 501, and controls the top foot 502 to stop extending, while the other top feet 502 continue to extend until all top feet 502 maintain stable contact with the ground. In this way, the device can automatically adapt to different terrain conditions, ensure that the best and most stable support contact area can be obtained under various complex ground conditions, effectively maintain the stability of the overall center of gravity of the device, reduce the risk of tipping due to uneven ground or load changes, and provide a reliable basic guarantee for the high-altitude power construction of the device; finally, the controller 501 can retract each top foot 502 synchronously, and the device can be easily transferred to a new working position or finish work.
[0045] Combine Figure 1 、 Figure 12 and Figure 13 As shown, the device also includes: a stabilization component arranged on the mounting shell 1011 of the power bearing seat 101, the stabilization component is used to increase the stability of the device, and a group of stabilization components are arranged on the left and right sides of the mounting shell 1011, and each group of stabilization components includes: an expansion rack 601 slidably mounted on the front and rear sides of the mounting shell 1011, an extension leg 602 slidably mounted on the front and rear sides of the mounting shell 1011, and a contact wheel 603 rotatably mounted on the bottom of the extension leg 602; each extension leg 602 is slidably mounted corresponding to each expansion rack 601, and the displacement direction of the extension leg 602 relative to the expansion rack 601 is perpendicular to the displacement direction of the expansion rack 601 relative to the mounting shell 1011; the contact wheel 603 enables the extension leg 602 to smoothly perform horizontal displacement.
[0046] Combine Figure 1 、 Figure 12 and Figure 13As shown, the device also includes: a second transmission assembly arranged between the stabilization assembly and the lifting frame 102, the second transmission assembly realizes the linkage extension function of the stabilization assembly during the operation of the lifting frame 102, each group of stabilization assemblies is correspondingly connected to a group of second transmission assemblies, the second transmission assembly includes: a convex shaft 604 fixedly mounted on the extension leg 602, a connecting block 606 slidably mounted on the mounting shell 1011, and a transmission rod 607 rotatably mounted between the connecting block 606 and the unfolding frame 601; a guide groove 605 is provided in the mounting shell 1011, and the guide groove 605 is symmetrically distributed on the front and rear sides of the mounting shell 1011, wherein the guide groove 605 consists of an inclined section and a straight section, the inclined section is in the middle, and the straight section is on the outside, and the two sections are smoothly docked, and the convex shaft 604 will slide with the guide groove 605 so that the position of the extended leg 602 will be precisely guided; the connecting blocks 606 of the two groups of stabilizing components are respectively fixed to the two connecting shafts 1022 at the bottom position, and the two connecting blocks 606 move together with the two connecting shafts 1022, and the transmission rod 607 converts the displacement of the connecting block 606 into the displacement of the unfolding frame 601.
[0047] When the lifting frame 102 is extended and lifts the bottom plate 103 upward, the two connecting shafts 1022 at the bottom position will separate from each other under the action of the two vertical scissor units, driving the connecting blocks 606 in the two groups of stabilizing components to move toward the unfolding frame 601 in the group, and the transmission rod 607 drives the unfolding frames 601 on the front and rear sides to move outward synchronously, driving the extended legs 602 to extend from the mounting shell 1011 together. During the process, the extended legs 602 slide downward along the inclined section of the guide groove 605. When the convex shaft 604 moves to the straight section of the guide groove 605, the contact wheel 603 at the bottom of the extended legs 602 forms a stable contact with the ground; as the lifting frame 102 continues to extend and the height of the bottom plate 103 rises, the extended legs 602 continue to expand outward. At this time, the extended legs 602 The extended legs 602 only move horizontally. By using the stabilization component, a positive proportional relationship between the height and the support area is formed - the higher the base plate 103 is lifted, the greater the extension range of the extended legs 602, so that the total footprint of the device increases accordingly, and the stability of the device is automatically enhanced with the working height, thereby effectively reducing the risk of tipping over caused by the upward shift of the center of gravity of the device during high-altitude operations. In addition, the operation process of the stabilization component is automatically realized by the synchronous transmission of the telescopic movement of the lifting frame 102, thereby simplifying the operation process of the device; when the lifting frame 102 retracts, the connecting shaft 1022 is controlled to move toward each other, and the expansion frame 601 is pulled inward by the transmission rod 607, and the extended legs 602 are automatically retracted into the mounting shell 1011 along the trajectory of the guide groove 605 to achieve automatic storage.

At the same time, the unfolding frame 601 and the extension legs 602 are unfolded to expand the floor area of the device; after the bottom plate 103 is lifted to the working position, turn off the servo motor 1025, and the worker performs electrical construction work.
[0049] S2. When a dangerous situation occurs, the worker's center of gravity shifts and contacts the sensor 201. The sensor 201 senses the force and transmits a signal to the control system. The control system determines that an unexpected situation has occurred, and then controls the support plate 202 to rotate and fold down to lower the height of its support surface, thereby changing the worker's center of gravity. At the same time, the plug 403 disengages from the socket 401, unlocking the lock between the fence 104 and the bottom plate 103. The buffer frame 302 applies a force opposite to the impact direction to the worker through the fence 104, so that the buffer frame 302 and the support plate 202 work together to provide double protection for the worker.
[0050] S3. After the crisis is resolved, the buffer frame 302 resets the relative position relationship between the fence 104 and the bottom plate 103. At this time, the support plate 202 is manipulated to reverse and restore its support surface height; during the reset process, the plug block 403 is inserted into the socket 401 to re-lock the fence 104 and the bottom plate 103.
