Description

Technical Field

[0001] This invention belongs to the field of photovoltaic construction technology, specifically relating to a mobile and positioning elevated construction frame for photovoltaic installation. Background Technology

[0002] With the continuous development and expansion of the photovoltaic industry in China, more and more distributed photovoltaic power stations in mountainous areas are being built. During the construction of photovoltaic power stations, it is generally required that the lowest point of the photovoltaic modules be about 1.5m above the ground. Therefore, construction workers usually use scaffolding (mobile scaffolding, frame scaffolding) or ladders to install photovoltaic brackets and photovoltaic modules. However, due to the influence of terrain, when workers are on uneven installation ground such as mountain slopes, scaffolding is not only heavy and inconvenient to move, affecting construction efficiency, but also difficult to place stably, which can easily lead to tipping over and poses a significant safety hazard. Ladders are placed at an angle on the pile foundation. Without the assistance of construction workers, the ladders are also prone to slippage and tipping over. In addition, the limited operating space during construction seriously affects the construction progress, increases the construction difficulty, and reduces the installation efficiency of photovoltaic modules.

[0003] Chinese invention patent application CN116591448A discloses a novel construction platform for a distributed photovoltaic power station, comprising two photovoltaic columns, platform supports respectively connected to the two photovoltaic columns, and a slidable step on top of the platform support. The platform support includes a base, a lifting seat connected to the base via a linkage assembly, a foot pedal mechanism disposed on the lower end face of the lifting seat and capable of driving the linkage assembly to rise and fall, a fixed clamp connected to the base, a movable clamp connected to the lifting seat, and a bracket disposed on the movable clamp for slidably supporting the step. The construction platform provided by this invention is applicable to photovoltaic module supports and elevated construction of photovoltaic modules on different terrains, enabling rapid installation of the construction platform, ensuring the safety of construction operations, effectively reducing the labor intensity and difficulty of construction personnel, and improving construction efficiency.

[0004] Although the above-mentioned device can achieve rapid installation of the construction platform, the lifting of its lifting seat requires manual stepping, which is not only labor-intensive for construction workers, but also has low lifting efficiency. Moreover, the lifting seat of the construction platform is only positioned by ratchet and pawl after reaching the designated height, and its positioning strength is limited. Under excessive load on the lifting plate, positioning failure may occur. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide a movable and positioning aerial construction frame for photovoltaic installation, which can efficiently and labor-savingly raise and lower the construction frame and effectively ensure the positioning of the construction frame after raising and lowering.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A mobile positioning aerial work platform for photovoltaic installation includes two fixed columns, two bases, two sets of lifting mechanisms and a support mechanism. The bottom ends of the fixed columns are connected to the bases. The lifting mechanisms are located on the top of the bases and the support mechanism is located on the top of the lifting mechanisms.

Two sliders are slidably connected in the first sliding groove, and each slider is connected to a drive plate. The two drive plates are spaced apart, and teeth are provided on the opposite surfaces of the drive plates.

[0009] Preferably, a reinforcing mechanism is provided between the support plate and the drive mechanism. The reinforcing mechanism includes a working box, a fixing plate connected to the bottom of the working box, and a drive motor connected to the working box. The front of the work box is equipped with a clamping mechanism, which includes a housing.

A turntable is rotatably connected to the top of the housing. A fixed rod is eccentrically positioned on the top of the turntable. A hollow sleeve is fitted onto the fixed rod, and the hollow sleeve has a rounded rectangular through-slot that matches the fixed rod. A connecting rod is located at the middle of the front end of the hollow sleeve, and the length direction of the rounded rectangular through-slot is perpendicular to the axis of the connecting rod. The connecting rod extends through the front of the work box, and a sliding plate is located at the front end of the connecting rod. A sliding rod is located at the bottom of the sliding plate. The clamping claws have irregularly shaped through-slots that match the sliding rod. When the sliding rod moves forward within the irregularly shaped through-slots, the clamping claws gradually close; when the sliding rod moves backward within the irregularly shaped through-slots, the clamping claws gradually separate. The turntable is connected to a rotating mechanism for driving the turntable to rotate.

[0010] Preferably, the rotating mechanism includes a second drive shaft that extends through the left and right sides of the housing. The second drive shaft has a first bevel gear inside the housing, and a rotating shaft is provided at the bottom of the turntable. The rotating shaft extends through the housing and into its interior, and a second bevel gear that meshes with the first bevel gear is provided at the end of the rotating shaft. A ratchet is provided on each of the left and right sides of the second drive shaft on the outside of the housing. The sidewalls at both ends of the second drive shaft are provided with teeth, and the teeth at both ends of the second drive shaft mesh with the toothed plates of the pedal mechanism. The pedal mechanism is used to drive the second drive shaft to rotate.

[0011] Preferably, there are two pedal mechanisms, each comprising a pedal box, an arc-shaped plate, a pedal, and a toothed plate. The two pedal boxes are located inside the working box on the left and right sides of the housing. Each pedal box has a first groove, and the two ends of the arc-shaped plate are slidably connected within the first groove. A spring connects the arc-shaped plate to the bottom of the first groove. Vertical plates are provided on both the left and right sides of the rear side of the pedal box. The pedal is rotatably connected between the two vertical plates. A toothed plate, which is an arc-shaped plate, is provided at the front end of the pedal. The pivot shaft connecting the toothed plate and the pedal to the vertical plates is coaxial. The top of the working box is open, and the support plate has an opening that matches the pedal.

[0012] Preferably, slider one and slider two are slidably connected to the front and rear sides of the first groove of the pedal box, and the two ends of the arc plate are respectively connected to the two sliders; slider one is connected to a connecting plate through the side wall of the first groove near the shell, and the connecting plate is rotatably connected to a pawl that matches the ratchet, and a spring is connected between the pawl and slider one.

[0014] Preferably, the limiting mechanism further includes a card box and a pressing rod. The card slot allows the card box to enter and exit. The side wall of the card slot is also provided with a hemispherical groove that matches the card-attaching post. The front end of the card-attaching post is hemispherical. The pedal box has a second groove that matches the card box and the pressing rod. A toothed cylinder is rotatably connected inside the card box, and a locking post is threaded into the toothed cylinder. The card box has a through hole that matches the locking post. A first lifting plate is slidably connected inside the card box. The first lifting plate has a rack that meshes with the toothed cylinder. A vertical rod is provided at the bottom of the first lifting plate. The bottom of the vertical rod passes through the bottom of the card box and is connected to a base plate. A spring is fitted on the outside of the vertical rod. The two ends of the spring are respectively connected to the bottom of the card box and the base plate. A swing plate is hinged to the bottom end of the pressing rod. The swing plate is also hinged to the base plate. A second rotating rod is provided in the second groove. The second rotating rod passes through the middle of the swing plate. When the pressing rod is pressed down, the side of the swing plate connected to it moves down, and the other side connected to the base plate will lift up. The rack drives the toothed cylinder to rotate, causing the locking post to retract into the toothed cylinder.

[0015] Preferably, the top of the work box is provided with a connecting frame, the support plate is slidably connected in the connecting frame, the front end of the connecting frame is provided with a movable clamp, and the inner wall of the movable clamp is provided with a number of ball bearings.

[0017] The beneficial effects of this invention are: 1. The drive motor drives the drive shaft to rotate, causing the drive plates to move closer or separate, which in turn causes the sliders to move closer or separate, thereby causing the X-shaped telescopic parts to open and close. This allows the lifting mechanism to lift the support plate, eliminating the need for manual operation of the support plate and making it more labor-saving and efficient.

[0018] 2. In the preferred embodiment, the construction frame is also equipped with a clamping mechanism to clamp the fixed column after the support plate reaches the specified height, and to complete the positioning of the construction frame in conjunction with the drive motor (the drive motor stops rotating after reaching the specified height, and the drive shaft stops rotating, which can limit the movement of the drive plate and thus complete the positioning, but the positioning capability is relatively limited); the clamping mechanism is driven to rotate by a stepping mechanism, and there are matching ratchet and pawl between the stepping mechanism and the clamping mechanism to prevent the second drive shaft from reversing and causing the clamping pawl to loosen; in addition, there is a locking mechanism to further limit the rotation of the second drive shaft, and together with the ratchet and pawl, it can more reliably ensure that the clamping pawl can stably clamp the fixed column, and achieve reliable positioning of the support plate.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] It should be noted that the terms such as "upper", "lower", "left", "right", "front", and "back" used in the invention are only for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0023] First, let's introduce some of the accompanying drawings. To more clearly and intuitively demonstrate the specific structure of this application, some of the drawings have removed the obscured structures to better show their internal details. However, these structures actually exist; they are simply omitted from the drawings. Specifically: Figure 6 Work box 301 in Figure 6 The left lateral wall was removed; Figure 8 The lower left corner of the toothed plate 514 was cut off to better show the connecting plate 512 and the pawl 513. Part of the right side wall of the pedal box 501 was cut off to show its internal limiting mechanism. Figure 13 :exist Figure 13 In terms of orientation, the front side wall of the pedal box 501 has been partially cut away, mainly the front vertical plate 505 and part of the front structure of the limiting mechanism, in order to better expose its internal structure.

[0024] like Figure 1-15As shown, this application provides a movable positioning climbing construction frame for photovoltaic installation, including two fixed columns 1, two bases 102, two sets of lifting mechanisms 8 and a support mechanism 4. The bottom end of the fixed column 1 is connected to the base 102. The base 102 is provided with a fixing clamp 101 on its side. The bottom end of the fixed column 1 is connected to the fixing clamp 101. The fixing clamp 101 can be formed by bolting two mirror-arranged semi-circular clamps together to form a whole circular clamp.

[0025] The lifting mechanism 8 is located on the top of the base 102, and the support mechanism 4 is located on the top of the lifting mechanism 8. The lifting mechanism 8 includes several sets of X-shaped telescopic members, the ends of each set of X-shaped telescopic members are hinged to each other, and the bottom two ends of the lowest X-shaped telescopic member are hinged to the base 102. The X-shaped telescopic component includes two sets of components arranged symmetrically front and rear. Each set of components includes two intersecting second lifting plates 801, meaning each set of components consists of two second lifting plates 801 forming an X shape. Each second lifting plate 801 has a through groove in the middle, and a sliding post 803 is slidably connected in the through groove of the four second lifting plates 801. That is, the sliding post 803 passes through the through groove of the four second lifting plates 801 sequentially from front to back, connecting them into a whole. The ends of corresponding second lifting plates 801 in the two sets of components are connected by connecting posts 802. The connecting posts 802 hinge the corresponding ends of the upper and lower X-shaped telescopic components. For details, please refer to [reference needed]. Figure 2 In this context, for example, the bottommost and second-to-last X-shaped telescopic components are referred to as the first and second layer X-shaped telescopic components, respectively. The two sets of components of the same layer X-shaped telescopic component are referred to as the front component and the rear component, respectively. Then, the connecting column 802 connects the corresponding upper ends of the front and rear components of the first layer X-shaped telescopic component (the upper end of the second lifting plate 801) and the corresponding lower ends of the front and rear components of the second layer X-shaped telescopic component (the lower end of the second lifting plate 801).

[0026] like Figure 1 , 3 As shown in Figures 6 and 7, the support mechanism 4 includes a support plate 404. Two drive mechanisms 2 are connected below the support plate 404. A reinforcing mechanism 3 is also provided between the support plate 404 and the drive mechanism 2. The reinforcing mechanism 3 includes a working box 301. A fixing plate 205 is connected to the bottom of the working box 301, and a drive motor 303 is connected to the working box 301. A connecting frame 403 is provided at the top of the working box 301. The support plate 404 is slidably connected in the connecting frame 403. A movable clamp 401 is provided at the front end of the connecting frame 403. A plurality of ball bearings 402 are provided on the inner wall of the movable clamp 401.

[0027] The driving mechanism 2 includes a fixed plate 205. The fixed plate 205 has a first sliding groove 204 on its front and rear sides. Two sliders 203 are slidably connected in the first sliding groove 204. Each slider 203 is connected to a driving plate 202. The two driving plates 202 are spaced apart. The opposite surfaces of the driving plates 202 are provided with teeth. A first driving shaft 207 is provided between the driving plates 202. The bottom end of the first driving shaft 207 is provided with teeth that mesh with the teeth of the driving plates 202. The first driving shaft 207 is connected to the output shaft of the driving motor 303. The top two ends of the uppermost X-shaped telescopic member are respectively hinged to the two sliders 203.

[0028] like Figure 3 , 4 As shown in Figure 6, a first mounting plate 302 is provided on the rear side of the working box 301, and a drive motor 303 is mounted on the first mounting plate 302. The output shaft of the drive motor 303 is provided with a third bevel gear 304. A second mounting plate 206 is provided on the rear side of the fixed plate 205, and a first drive shaft 207 is rotatably connected to the second mounting plate 206. A fourth bevel gear 201 that meshes with the third bevel gear 304 is provided on the top of the first drive shaft 207.

[0029] During use, the drive motor 303 sequentially drives the third bevel gear 302, the fourth bevel gear 201 and the first drive shaft 207 to rotate. Different rotation directions of the first drive shaft 207 will cause the two drive plates 202 to move closer to each other or further away, thereby driving the X-shaped telescopic component to open and close, completing the lifting mechanism 8 driving the support mechanism 4 to lift.

[0030] In this embodiment, the drive plate 202 is an L-shaped plate, with its shorter plate connected to the slider 203 and its longer plate extending rearward (specifically as shown in the figure). Figure 3 and 5 As shown), the two long plates are arranged at intervals relative to each other, and the opposite surfaces of the long plates are toothed. This allows the drive motor 303 to be located on the rear side of the work box 301 (or, if the fixing plate 205 is thick enough, it can be directly located on the rear side of the fixing plate 205). Of course, the drive plate 202 does not have to be L-shaped. For example, it can be a regular rectangular plate, with one in front of the other on the two sliders 202. The two rectangular plates can be arranged at intervals relative to each other. However, in this case, the drive motor 303 must be located at the bottom of the fixing plate 205, with the output shaft vertically downward and connected to the first drive shaft 207. This is how the first drive shaft 207 can be connected between the two rectangular plates.

[0031] like Figure 6 , 11As shown in Figure 12, the front side of the work box 301 is provided with a clamping mechanism 6. The clamping mechanism 6 includes a housing 601. The front side of the housing 601 is symmetrically hinged with clamping claws 610. The clamping claws 610 extend through the front side of the work box 301. That is, the front side of the work box 301 is provided with a through groove that matches the clamping claws 610, allowing the clamping claws 610 to rotate around their hinge points.

[0032] A turntable 604 is rotatably connected to the top of the housing 601. A fixing rod 605 is eccentrically mounted on the top of the turntable 604. A hollow sleeve 606 is fitted onto the fixing rod 605. The hollow sleeve 606 has a rounded rectangular through groove that matches the fixing rod 605. A connecting rod 607 is located in the middle of the front end of the hollow sleeve 606. The length direction of the rounded rectangular through groove is perpendicular to the axis of the connecting rod 607. In this way, the left and right deflection of the fixing rod 605 can be offset by moving left and right within the hollow sleeve 606. The hollow sleeve 606 will only move back and forth with the connecting rod 607.

[0033] The connecting rod 607 extends through the front of the work box 301 (the front of the work box 301 also has a through groove that matches the connecting rod 607, allowing the connecting rod 607 to swing left and right within a certain range). A sliding plate 608 is provided at the front end of the connecting rod 607, and a sliding rod 609 is provided at the bottom of the sliding plate 608. The clamping claw 610 has a shaped through groove that matches the sliding rod 609. When the sliding rod 609 is in the shaped through groove (the specific structure of the shaped through groove can be found in...), the connecting rod 607... Figure 11 When the sliding rod 609 moves forward in the groove, the gripping claw 610 gradually closes; when the sliding rod 609 moves backward in the groove, the gripping claw 610 gradually separates; the turntable 604 is connected to a rotating mechanism for driving the turntable 604 to rotate.

[0034] The rotating mechanism includes a second drive shaft 602, which passes through the left and right sides of the housing 601. The second drive shaft 602 has a first bevel gear inside the housing 601. The bottom of the turntable 604 has a rotating shaft that passes through the housing 601 and extends into it. The end of the rotating shaft has a second bevel gear that meshes with the first bevel gear. A ratchet 603 is provided on each of the left and right sides of the second drive shaft 602 on the outside of the housing 601. The sidewalls at both ends of the second drive shaft 602 are provided with teeth, and the teeth at both ends of the second drive shaft 602 mesh with the toothed plates 514 of the pedal mechanism 5. The pedal mechanism 5 is used to drive the second drive shaft 602 to rotate.

[0035] like Figure 6 , 8As shown in Figures 9, 10, 13, 14, and 15, there are two pedal mechanisms 5. Each pedal mechanism 5 includes a pedal box 501, an arc-shaped plate 502, a pedal 507, and a toothed plate 514. The two pedal boxes 501 are located inside the work box 301 on the left and right sides of the housing 601. The pedal box 501 has a first groove, and the two ends of the arc-shaped plate 502 are slidably connected to the first groove. A spring connects the arc-shaped plate 502 to the bottom of the first groove. The pedal box 501 has vertical plates 505 on both the left and right sides of its rear side. The pedal 507 is rotatably connected between the two vertical plates 505. When the pedal 507 is pressed down, it will compress the two ends of the arc-shaped plate 502 to slide towards both ends in the first groove. The arc-shaped plate 502 gradually flattens out. The sliding of the two ends of the arc-shaped plate 502 towards both ends will drive the corresponding mechanism to perform the corresponding function, which will be described in detail below.

[0036] The pedal 507 has a toothed plate 514 at its front end. The toothed plate 514 is an arc-shaped plate. The toothed plate 514 and the rotating shaft connecting the pedal 507 and the vertical plate 505 are coaxial. In this way, during the pressing and lifting process of the pedal 507, the toothed plate 514 can always maintain engagement with the end teeth of the second drive shaft 602, thereby effectively driving the second drive shaft 602 to rotate. If the toothed plate 514 and the rotating shaft connecting the pedal 507 and the vertical plate 505 are not coaxial, then during the pressing and lifting process of the pedal 507, in addition to the up-and-down movement, there is also the forward-and-backward movement, which will cause the toothed plate 514 and the second drive shaft 602 to have relative displacement in the forward-and-backward direction, so that the two cannot maintain a constant engagement state and cannot effectively drive the second drive shaft 602 to rotate.

[0037] The top of the work box 301 is open, and the support plate 404 is provided with an opening that matches the foot pedal 507. During use, the construction worker sits on the support plate 404, and his legs are inserted into the work box 301 through the opening on the support plate 404. His feet are in contact with the foot pedal 507. The top of the foot pedal 507 is provided with several protrusions to increase the friction between the feet and the foot pedal 507.

[0038] Sliding slider 503 and sliding slider 504 are slidably connected to the front and rear sides of the first groove of the pedal box 501, respectively. The two ends of the arc-shaped plate 502 are connected to the two sliding sliders. A connecting plate 512 is connected to the sliding slider 503 near the side wall of the first groove, and the connecting plate 512 is rotatably connected to a pawl 513 that matches the ratchet 603. A spring connects the pawl 513 and the sliding slider 503 to maintain contact between the pawl 513 and the ratchet 603. (That is, the pawl 513 is pushed towards the ratchet 603). During the process of the arc plate 502 being pressed down and flattened, the slider 503 will gradually move towards the second drive shaft 602. When the arc plate 502 is pressed down to the maximum extent, the ratchet 603 and the pawl 513 come into contact (there may have been contact before this, but the pawl 513 may not be able to completely restrict the ratchet 603 from reversing). At this time, the pawl 513 can prevent the ratchet 603 from reversing, thereby preventing the clamping pawl 610 from being released from the fixed post 1.

[0039] The stepping mechanism 5 is also equipped with a locking mechanism that can prevent the arc plate 502 (or stepping pedal 507) from lifting itself after it is pressed down to the maximum extent. In this way, after the clamping mechanism clamps the fixed column 1, the construction personnel do not need to continuously step on the stepping pedal 507 and can carry out other operations.

[0040] The locking mechanism includes a movable plate 510 and a limiting mechanism; the pedal 507 is provided with a second sliding groove 521 that matches the movable plate 510; a support rod 506 is rotatably connected between the two vertical plates 505, and a first rotating rod 508 is rotatably connected to each of the left and right sides of the support rod 506; the bottom end of the first rotating rod 508 abuts against the second slider 504, and the top end of the first rotating rod 508 is hinged to the movable plate 510; there can be only one movable plate 510, in which case the second sliding groove 521 must pass through the left and right sides of the pedal 507; there can also be two movable plates 510, in which case a second sliding groove 521 is provided on each of the left and right sides of the pedal 507, and a movable plate 510 is slidably connected in each second sliding groove 521; in either case, the length of the second sliding groove 521 must be greater than the length of the movable plate 510, so that the movable plate 510 can slide back and forth in the second sliding groove 521.

[0041] The bottom of the second slide groove 521 is provided with a through groove that matches the first rotating rod 508 and the slot 522, so that the first rotating rod 508 can rotate normally and the limiting mechanism can also enter and exit the second slide groove 521 to limit the moving plate 510.

[0042] The bottom of the movable plate 510 is provided with a slot 522 that matches the limiting mechanism; the limiting mechanism is provided with a locking post 523 that matches the slot 522 to control whether the movable plate 510 can disengage from the limiting mechanism.

[0043] The limiting mechanism also includes a card box 511 and a pressing rod 520. The pedal box 501 is provided with a second groove that matches the card box 511 and the pressing rod 520. The second groove is provided on the side of the pedal box 501. The card box 511 and the pressing rod 520 are disposed in the second groove, and their tops extend out of the second groove (see details). Figure 8 ).

[0044] A gear cylinder 515 is rotatably connected inside the card box 511, and a snap-fit ​​post 523 is threadedly connected inside the gear cylinder 515. Because the two are threadedly connected, the clockwise or counterclockwise rotation of the gear cylinder 515 will cause the snap-fit ​​post 523 to extend and retract inside the gear cylinder 515, thereby completing the control of the moving plate 510. The card slot 522 allows the card box 511 to enter and exit. A hemispherical groove matching the snap-fit ​​post 523 is also provided on the side wall of the card slot 522. The front end of the snap-fit ​​post 523 is hemispherical.

[0045] Card box 511 is provided with a through hole that matches the snap-fit ​​post 523, and the snap-fit ​​post 523 extends out of card box 511 through the through hole; a first lifting plate 516 is slidably connected inside card box 511, and a rack 524 that meshes with rack 515 is provided on the first lifting plate 516; a vertical rod 509 is provided at the bottom of the first lifting plate 516, and the bottom of the vertical rod 509 extends out of the bottom of card box 511 and is connected to a base plate 526; a spring is fitted on the outside of the vertical rod 509, and the two ends of the spring are respectively Connected to the bottom of the card box 511 and the base plate 526, this spring can keep the first lifting plate 516 at a stable height when it is not subjected to external force. At this height, the hemispherical front end of the locking post 523 just extends out of the card box 511. When the locking post 523 is subjected to external force and retracts into the gear cylinder 515, the spring will restore the first lifting plate 516 to its original position after the external force disappears, thereby driving the rack 524 to move, causing the gear cylinder 515 to rotate, and finally restoring the locking post 523 to its original position.

[0046] like Figure 10 As shown, a swing plate 519 is hinged to the bottom end of the pressing rod 520, and the swing plate 519 is also hinged to the base plate 526; a second rotating rod 518 is provided in the second groove, and the second rotating rod 518 passes through the middle of the swing plate 519; in this embodiment, a rectangular sleeve is also provided outside the pressing rod 520, and the rectangular sleeve is connected to the foot pedal box 501. The pressing rod 520 is slidably connected in the rectangular sleeve. The rectangular sleeve is provided to guide the pressing rod 520, but it is also acceptable not to provide the rectangular sleeve.

[0047] When the pressing rod 520 is pressed down, the side of the swing plate 519 connected to it moves down ( Figure 10 For ease of description, the direction in this paragraph is always indicated by the right side. Figure 10(Using the center direction as a reference), the left side of the swing plate 519 will tilt up and the top 517 will rise, thereby driving the first lifting plate 516 and the rack 524 to move upward. The rack 524 will drive the gear cylinder 515 to rotate, causing the locking post 523 to retract into the gear cylinder 515. Conversely, when the pressing rod 520 is lifted, the right side of the swing plate 519 tilts up and the left side descends. The rack 524 moves downward, which will drive the gear cylinder 515 to rotate in the opposite direction, causing the locking post 523 to extend out of the gear cylinder 515. The extension and retraction of the locking post 523 can be controlled by the pressing rod 520, thereby controlling whether the locking post 523 locks the moving plate 510. Locking the moving plate 510 will actually lock the pedal 507 and the rack 514, keeping them in a fixed position (that is, the pedal 507 is pressed down to the maximum extent, which can ensure that the clamping device 6 clamps the fixed post 1).

[0048] The locking mechanism works as follows: During the pressing of the pedal 507, the slider 504 moves backward, squeezing the bottom of the first rotating rod 508 to make it rotate. This causes the first rotating rod 508 to drive the moving plate 510 at its top to slide forward in the second slide groove 521. When the pedal 507 is pressed down to its maximum extent, the card box 511 enters the card groove 522 at the bottom of the moving plate 510. Because the front end of the locking post 523 is hemispherical, it can gradually retract into the toothed cylinder 515 during the downward movement of the moving plate 510, until the front end of the locking post 523 is engaged in the matching hemispherical groove on the side wall of the card groove 522. Without external force to continue squeezing the locking post 523, the locking post 523 will return to its initial state and be engaged in the spherical groove, restricting the movement of the moving plate 510. This completes the locking of the pedal 507 and the toothed plate 514, and thus completes the locking of the clamping mechanism 6.

[0049] When it is necessary to release the locked state, simply press down on the pressing rod 520, which will cause the locking post 523 to retract into the toothed cylinder 515, thereby causing the moving plate 510 to disengage from the limiting mechanism. If no external force continues to press down, the arc plate 502 will rise under the action of its bottom spring, thereby driving the pedal 507 and the toothed plate 514 to rise. The upward movement of the toothed plate 514 will cause the second drive shaft 602 to rotate in the opposite direction, causing the clamping claw 610 to release the fixing post 1. At this time, the height of the support mechanism 4 can be adjusted again.

[0050] The working principle of the movable positioning aerial work platform for photovoltaic installation provided in this application is as follows: First, fix the fixing column 1 and the base 102, then start the drive motor 303 to raise the support plate 404 to the specified height and then stop the drive motor 303 from rotating.

[0051] Afterwards, the construction worker steps on the pedal 507, causing the toothed plate 514 to move down and drive the second drive shaft 602 to rotate, which in turn drives the turntable 604 to rotate. The rotation of the turntable 604 causes the connecting rod 607 to move forward. During the forward movement of the sliding plate 608, the sliding rod 609 moves in the irregular groove of the clamping claw 610, so that the two clamping claws 610 come closer to each other and clamp the fixed column 1. When the pedal 507 is pressed down to the maximum extent, the clamping claws 610 completely clamp the fixed column 1, and the pedal 507 maintains this state under the action of the limiting mechanism until the pressing rod 520 is pressed down to release the locked state.
