Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic assembly installation, and in particular relates to an installation platform for photovoltaic assemblies. Background Art

[0002] When installing photovoltaic panels, the photovoltaic panels in an inclined state need to be fixed on the upper ends of two photovoltaic mounting columns. When the photovoltaic modules on the photovoltaic panels need to be installed, the operator needs to stand on a high scaffolding to install them. Since the photovoltaic panels are in an inclined state and the installation plane of the scaffolding is in a flat state, the operator cannot reach the photovoltaic modules at a high position and cannot install them. At this time, the scaffolding needs to be moved, which leads to a large installation workload and affects the installation efficiency. At the same time, the operator needs to bend over to operate the photovoltaic modules at a low position, which not only causes discomfort to the operator, but also affects the installation efficiency.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The present invention provides an installation platform for photovoltaic modules. When installing photovoltaic modules on an inclined photovoltaic panel, the support frame of the installation platform can adjust the inclination angle to match the photovoltaic panel. When the support frame is tilted and rotated, all the step plates are always in a horizontal state. At the same time, the arrangement angle of a row of step plates corresponds to the inclination angle of the support frame, thereby forming a stepped operating platform. In this way, when installing photovoltaic modules at a high place, the operator can directly step on the high step plate, and when installing photovoltaic modules at a low place, the operator can directly step on the low step plate. There is no need to stand on tiptoe to force the installation, nor is there any need to bend over to install. In this way, the installation of the entire photovoltaic panel can be completed by adjusting the installation platform only once, and there is no need to adjust the scaffolding multiple times. This not only greatly improves the installation efficiency of photovoltaic modules, but also ensures the safety and comfort of operators.

[0016] (2) The present invention provides a mounting platform for photovoltaic modules, wherein a support frame is fixedly connected to photovoltaic mounting columns on both sides by means of fixing clamps, which not only improves the overall mounting firmness of the mounting platform but also facilitates the adjustment of the tilt angle of the support frame; the first rotating shafts on both sides of the middle step plate are connected to the fixing clamps on both sides by means of polygonal columns, so that the support frame can adjust the tilt angle while ensuring that the middle step plate always remains horizontal, and all step plates are connected to the support frame by means of first connecting rods parallel to each other, so that all step plates always remain horizontal during the adjustment process, thereby realizing the process of adjusting all step plates from a horizontal operating platform to a stepped operating platform.

[0017] (3) The present invention provides a mounting platform for photovoltaic modules, wherein the second connecting rods of the left side guardrail and the right side guardrail are connected to the first connecting rod on the same side through the second transmission assembly. The second transmission assembly can ensure that the second connecting rod always remains parallel to the first connecting rod. Since the first connecting rod always remains parallel to the support frame during the adjustment process, the second connecting rod also always remains parallel to the support frame during the adjustment process. The front guardrail, the rear guardrail, and the plurality of second connecting rods form a parallelogram structure, so that the front guardrail and the rear guardrail always remain vertical during the adjustment process. When the support frame is transformed into an inclined state, the vertical front guardrail and the rear guardrail can provide sufficient protection for the operator, while also preventing the front guardrail and the rear guardrail from tilting and affecting the operator's operation.

[0018] (4) The present invention provides an installation platform for photovoltaic modules, wherein the length of the support legs can be adjusted individually. Thus, when encountering uneven ground, the length of each support leg can be adjusted individually, thereby ensuring that each support leg provides stable support for the support frame. A ground nail and a universal wheel are provided on the abutment seat at the lower end of each support leg. When the support leg needs to be fixed, the abutment plate is rotated until it contacts the ground and the ground nail is inserted to fix the lower end of the support leg. When the installation platform needs to be moved, the universal wheel is rotated until it contacts the ground and the first locking rod is inserted to move the installation platform. No manual handling is required, which is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Fig.11 As shown, the step plate 3 is a horizontally arranged square plate-shaped structure, and all the step plates 3 have the same shape and structure. A first rotating shaft 18 is fixedly arranged in the middle of the left and right end faces of the step plate 3, respectively. The first rotating shafts 18 on the left and right sides of the step plate 3 are rotatably connected to the left and right inner walls of the support frame 1, respectively. The first rotating shafts 18 on the same side of all the step plates 3 are arranged in a front-to-back horizontal direction. A third hinge seat 19 is fixedly arranged at the left and right ends of the front side edge of the upper end face of each step plate 3, and the hinge axis of the third hinge seat 19 is horizontally arranged along the left-right direction.

[0029] like Fig.12 , 13 As shown, the fixing clamp 4 includes a fixing seat 22 and two clamping claws 23. The fixing seat 22 is a cubic structure, and the two fixing seats 22 are respectively located on the left and right sides of the supporting frame 1.

[0030] A rotating hole is provided at the center of one end face of the fixed seat 22 close to the supporting frame 1, and a polygonal groove is provided at the inner center of the rotating hole. The second rotating shafts 20 on both sides of the supporting frame 1 are respectively rotated and inserted into the two rotating holes, and the polygonal columns 21 at the ends of the first rotating shafts 18 on both sides of the central step plate 3 are inserted into the polygonal grooves of the fixed seat 22 on the same side.

[0031] Two clamping jaws 23 are rotatably arranged on the end face of one side of the fixing seat 22 away from the supporting frame 1, and a semicircular clamping groove is respectively arranged at the end faces of the two clamping jaws 23 close to each other, and two bolt holes are respectively arranged at the ends of the two clamping jaws 23 away from the fixing seat 22; when the two clamping jaws 23 contact each other, the bolt holes on the two clamping jaws 23 correspond to each other, and after the fixing bolts 24 are inserted into the corresponding two bolt holes and the fixing nuts are screwed, the two clamping jaws 23 are fixed. A locking plate 25 is respectively fixed on the front and rear sides of the fixing seat 22, and an outer locking hole 26 is arranged on the locking plate 25, and the outer locking hole 26 is an internal threaded hole.

[0032] Two inner locking holes 27 are respectively arranged on the outer sides of the left and right sides of the support frame 1, and the two inner locking holes 27 are respectively located on both sides of the second rotating shaft 20. When the support frame 1 is in a horizontal state, the two inner locking holes 27 correspond to the two outer locking holes 26 on the fixing seat 22 on the same side. The same third locking rod 28 is inserted into the corresponding outer locking holes 26 and the inner locking holes 27, and the third locking rod 28 is screwed with the outer locking holes 26, so as to fix the angle of the support frame 1 and keep the support frame 1 in a horizontal state.

[0033] like Figure 5 , 6 As shown, the first transmission assembly includes a first connecting rod 29, which is hinged to the third hinge seat 19 on the same side of all the step plates 3, and the first connecting rod 29 is extended along the front-rear horizontal direction.

[0034] When the support frame 1 is in a horizontal state, the first rotating shafts 18 on the same side of all the step plates 3 are arranged along the front-to-back horizontal direction, and the first connecting rod 29 is also in a front-to-back horizontal state. At this time, all the step plates 3 are in a horizontal state and are at the same height, that is, all the step plates 3 are spliced ​​into a complete horizontal operating platform, and the operator can stand on the step plates 3 to operate.

[0035] like Figure 5 As shown, two symmetrical front side guardrails 30 are rotatably arranged at the front side edge of the upper end surface of the support frame 1, and the hinge axis between the front side guardrail 30 and the support frame 1 is arranged horizontally along the left-right direction. A guardrail door 31 is slidably arranged on the right side front side guardrail 30, and an unlockable lock is arranged between the guardrail door 31 and the left side front side guardrail 30.

[0036] like Figure 5 As shown, two symmetrical rear guardrails 32 are rotatably arranged at the rear edge of the upper end surface of the support frame 1, and the hinge axis between the rear guardrail 32 and the support frame 1 is arranged horizontally along the left-right direction. A guardrail door 31 is slidably arranged on the right rear guardrail 32, and an unlockable lock is arranged between the guardrail door 31 and the left rear guardrail 32.

[0037] The front side guardrail 30 and the rear side guardrail 32 are kept parallel.

[0038] like Figure 5 As shown, a left side guardrail is arranged between the left end face of the left front side guardrail 30 and the left end face of the left rear side guardrail 32, and a right side guardrail is arranged between the right end face of the right front side guardrail 30 and the right end face of the right rear side guardrail 32. The left side guardrail and the right side guardrail are both composed of a plurality of second connecting rods 33 parallel to each other, the second connecting rod 33 is parallel to the first connecting rod 29, and the front and rear ends of the second connecting rod 33 are respectively hinged to the front side guardrail 30 and the rear side guardrail 32 on the same side.

[0039] like Figure 7 , 22 As shown in Figures 23, the left guardrail and the right guardrail are connected to the first connecting rod 29 on the same side through a set of second transmission components. The second transmission component includes a transverse slide frame 34, a longitudinal slide frame 35, and a slider 36. A transverse slide frame 34 is fixedly arranged at the front and rear ends of the end face of the first connecting rod 29 away from the step plate 3. The transverse slide frame 34 is perpendicular to the first connecting rod 29, and the end of the transverse slide frame 34 away from the first connecting rod 29 extends upward; a transverse slide is arranged on the end face of the side of the transverse slide frame 34 close to the step plate 3, and the transverse slide is a T-slot structure. A longitudinal slide frame 35 is fixedly arranged on the outer side of the second connecting rod 33 at the bottom, and the extension direction of the longitudinal slide frame 35 is parallel to the extension direction of the second connecting rod 33. A longitudinal slide is arranged on the end face of the side of the longitudinal slide frame 35 close to the transverse slide frame 34, and the longitudinal slide is a T-slot structure. The slider 36 includes two fixedly connected T-blocks, one of which is slidably connected to the inside of the transverse slide groove, and the other T-block is slidably connected to the inside of the longitudinal slide groove.

[0040] Through the cooperation of the transverse slide frame 34, the longitudinal slide frame 35 and the slider 36, the second connecting rod 33 and the first connecting rod 29 always remain parallel. When the angle of the first connecting rod 29 changes, the angle of the second connecting rod 33 also changes accordingly.

[0041] The working principle of the present invention is: When the installation platform is in the initial state, the four support legs 2 are in a vertical state, the abutment seats 9 at the lower ends of the support legs 2 are in a locked state, the universal wheels 13 are in contact with the ground, and the two support legs 2 on the same side are locked by the second locking rod 17. At this time, the support frame 1 is in a horizontal state, all the step plates 3 are on the same horizontal plane, and the front guardrail 30 and the rear guardrail 32 are in a vertical state.

[0042] When the photovoltaic module needs to be installed, the installation platform is pushed, and the installation platform moves through the four universal wheels 13 until the installation platform moves between the two photovoltaic installation columns 37, ensuring that the fixing clips 4 on the left and right sides correspond to the two photovoltaic installation columns 37. Then the four universal wheels 13 are locked.

[0043] Next, start controlling the outer rods 6 of the four supporting legs 2 to rotate. Since the outer rods 6 are screwed to the inner rods 5, the inner rods 5 slide upward, and the inner rods 5 drive the supporting frame 1 to start rising until the fixing clips 4 on both sides of the supporting frame 1 correspond to the supporting grooves on the photovoltaic mounting columns 37 on both sides.

[0044] Then, the two clamping claws 23 on the fixing seat 22 are brought closer to each other until the two clamping claws 23 clamp the support grooves on the photovoltaic mounting column 37, and then the two clamping claws 23 are fixed by the fixing bolts 24 and the fixing nuts, so that the fixing clamp 4 is fixedly connected to the photovoltaic mounting column 37, so that the support frame 1 is fixed to the photovoltaic mounting columns 37 on both sides. By connecting the fixing clamp 4 with the support grooves of different heights on the photovoltaic mounting column 37, the height of the support frame 1 can be adjusted. The third locking rod 28 is rotated outward, and the support frame 1 can be rotated relative to the fixing clamps 4 on both sides.

[0045] Then, pull out the second locking rod 17 and the first locking rod 15, so that the support leg 2 and the abutment seat 9 can start to rotate. The support frame 1 is controlled to rotate by the support leg 2 so that the inclination angle of the support frame 1 is adapted to the inclination angle of the photovoltaic panel above it. Then the support leg 2 is placed at an angle, and the outer rod 6 is rotated so that the outer rod 6 can slide on the outside of the inner rod 5, and the outer rod 6 is slid downward until the lower end surface of the abutment plate 10 is in contact with the ground, and the length adjustment of the support leg 2 is completed. At this time, the abutment plate 10 is in a horizontal state, the support plate 11 is in an inclined state, and the universal wheel 13 is out of contact with the ground. Then the ground nail 12 is inserted into the ground after passing through the fixing hole, so as to fix the abutment plate 10 to the ground, so that the support leg 2 can play a stable supporting role for the installation platform, ensuring that the support frame 1 can be stably maintained at the current inclination angle.

[0046] During the rotation of the support frame 1, since the polygonal columns 21 at the ends of the first rotating shaft 18 on both sides of the middle step plate 3 are inserted into the polygonal grooves of the fixing seats 22 on the same side, the fixing seats 22 on both sides cannot rotate, so that the middle step plate 3 cannot rotate either. As the support frame 1 continues to tilt and rotate, the heights of the step plates 3 on the front and rear sides begin to change, and the first connecting rod 29 also begins to tilt and rotate. The inclination angle of the first connecting rod 29 always remains the same as the inclination angle of the support frame 1. Since all the step plates 3 are hinged to the support frame 1 and all the step plates 3 are connected by the first connecting rod 29, all the step plates 3 are kept at the same angle; the middle step plate 3 cannot rotate and always remains horizontal, so that all the step plates 3 remain horizontal. In this way, all the step plates 3 gradually transform into a stepped operating platform.

[0047] During the tilting and rotating process of the first connecting rod 29, the first connecting rod 29 drives the horizontal slide frame 34 to move synchronously. Since the slider 36 is slidably connected to the inside of the horizontal slide and the inside of the longitudinal slide at the same time, it is ensured that the longitudinal slide frame 35 is always in a vertical state with the horizontal slide frame 34, so that the second connecting rod 33 and the first connecting rod 29 are always kept in a parallel state. During the tilting and rotating process of the first connecting rod 29, the second connecting rod 33 also gradually changes from a horizontal state to an inclined state. Since the front guardrail 30, the rear guardrail 32, and the plurality of second connecting rods 33 form a parallelogram structure, the front guardrail 30 and the rear guardrail 32 are always in a vertical state.

[0048] When the angle of the support frame 1 is fixed, the ladder is placed on the support frame 1 corresponding to the guardrail door 31 on the lower side. The operator climbs up the ladder, unlocks the lock on the guardrail door 31 and pushes the guardrail door 31 open. The operator can enter the interior of the installation platform and then close the guardrail door 31 again. After the operator enters the installation platform, he can stand on the step boards 3 of different heights to operate. When the photovoltaic panel needs to be installed at a high position, the operator only needs to step on the high step board 3. When the photovoltaic panel needs to be installed at a low position, the operator only needs to step on the low step board 3, ensuring that the photovoltaic components of different heights of the photovoltaic panel can be installed conveniently. When the support frame 1 is transformed into an inclined state, the vertical front guardrail 30 and the rear guardrail 32 can provide sufficient protection for the operator, and also prevent the front guardrail 30 and the rear guardrail 32 from tilting and affecting the operator's operation.

[0049] When the installation platform needs to be moved, the ground nail 12 on the abutment plate 10 is pulled out, and then the outer rod 6 is rotated again to make the outer rod 6 slide upward. After the outer rod 6 slides upward for a distance, the abutment seat 9 is rotated so that the support plate 11 remains perpendicular to the axis of the outer rod 6. At this time, the first plug hole corresponds to the second plug hole, and the first locking rod 15 is inserted into the corresponding first plug hole and second plug hole, so that the angle of the abutment seat 9 is fixed and cannot continue to rotate. Then continue to slide the outer rod 6 upward and rotate the support leg 2 until the outer rod 6 is in a vertical state and the universal wheel 13 contacts the ground, and the length adjustment of the support leg 2 is completed. At this time, all the support legs 2 remain vertical, and the angle of the abutment seat 9 at the lower end of the support leg 2 is fixed, and the universal wheel 13 at the lower end of the support leg 2 contacts the ground; then the second locking rod 17 is inserted into the locking seat 16 on the two support legs 2 on the same side, so that the support leg 2 cannot rotate and remains in a vertical state, and the installation platform returns to the initial state. Then, the fixing clips 4 on both sides are disconnected from the first photovoltaic installation column 37 and the second photovoltaic installation column 37 respectively, so that the installation platform can be moved by the universal wheels 13 to carry out the installation of the next photovoltaic panel.
