Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a rooftop photovoltaic support mobile trolley. Background Technology

[0002] Photovoltaic power generation refers to a power generation method that directly converts solar radiation into electrical energy. Photovoltaic power generation is based on the photovoltaic effect principle, using solar cells to directly convert solar energy into electrical energy. A photovoltaic cell is a semiconductor device with light-to-electricity conversion characteristics, which directly converts solar radiation energy into direct current.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: When photovoltaic panels need to be installed, they are installed on the roof to increase illuminance. During installation, supports are needed to support the photovoltaic brackets. Since traditional supports lack specialized installation tools, the supports hoisted to the roof need to be manually carried to the positioning point. Manual carrying is laborious and can easily damage the cement supports. Therefore, to address the above problems, a roof photovoltaic support moving trolley is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The roof photovoltaic support trolley of this utility model includes a support frame and a lifting device. Support wheels are rotatably connected to both sides of the support frame. A support rod is fixedly connected to the upper surface of the support frame. A lifting device is fixedly connected to the bottom end of the support rod. A hook is fixedly connected to the bottom end of the lifting device. Pressing down the support rod causes the support rod to drive the lifting device and the hook to rise. The hook drives the support trolley to move. Then, pushing the support rod causes the support rod to drive the support wheels to roll. By setting up the support frame, support wheels, support rod, lifting device and hook, the support trolley can be moved easily, thereby facilitating the installation of the support trolley.

[0006] Preferably, the support frame has two support rods fixedly connected to its surface, and the two support rods are symmetrically distributed with respect to the central axis of the support frame. When the support frame is under force, the support frame will transmit the force to the support rods, and the support rods can increase the strength of the support frame.

[0007] Preferably, a fixing rod is fixedly connected to the surface of the support rod and the support frame. When the support frame and the support rod are subjected to force, the force will be transmitted to the fixing rod, which can increase the strength of the support rod and the support frame.

[0008] Preferably, a storage block is fixedly connected to the upper surface of the support frame, and the inner wall of the storage block is slidably connected to the surface of the support rod. When the support rod is installed, the support rod slides on the inner wall of the storage block. The storage block is designed to bear the pressure at the connection between the support frame and the support rod.

[0009] Preferably, the bottom end of the support rod is provided with multiple adapter holes, the inner wall of the adapter holes of the support frame and the support rod is provided with bolts, the inner wall of the adapter hole of the support rod and the inner wall of the lifting device are provided with two positioning pins, and the inner wall of the adapter hole of the support rod, the inner wall of the support frame and the inner wall of the fixing rod are all provided with limit pins. By opening the adapter holes, the support rod can be fixed at different positions on the support frame, and the lifting device and the fixing rod can also be installed on the support rod.

[0010] Preferably, the surface of the support rod is provided with a limiting device, which includes a placement plate. The side wall of the placement plate is fixedly connected to the surface of the support rod. A threaded rod is rotatably connected to the inner surface of the placement plate. The surface of the threaded rod is provided with two opposite thread lines. Two moving blocks are threadedly connected to the surface of the threaded rod. A brake pad is fixedly connected to the side wall of the moving block. The brake pad is located on one side of the support wheel. The moving block drives the brake pad to move, and the brake pad presses against the surface of the support wheel. By setting the placement plate, the threaded rod, the moving blocks, and the brake pad, the rotation of the support wheel can be restricted, thereby achieving a braking effect.

[0011] Preferably, two support bars are fixedly connected to the side wall of the placement plate and the surface of the support rod. The surface of the movable block is provided with a threaded hole. The inner wall of the threaded hole of the movable block is threadedly connected to the surface of the threaded rod. When the threaded rod rotates, the threaded rod rotates on the inner wall of the threaded hole. The opening of the threaded hole facilitates the rotation of the threaded rod on the inner wall of the movable block.

[0012] The advantages of this utility model are:

[0013] 1. When the support pier needs to be installed, this utility model pushes the support rod to move the support frame and lifting device. When the support frame moves, it will cause the support wheels to roll on the roof. After the lifting device moves to the appropriate position, the support pier is hung on the hook. Then, the support rod is pressed down to make the support rod move the lifting device, hook and support pier to rise. Then, the support rod is pushed to move the support pier to the installation position. When the support rod is under force, it will transmit the force to the storage block, the fixing rod and the support rod. When installing the support rod, the bolt is rotated into the inner wall of the support frame and the adapter hole. When installing the lifting device, the positioning pin is rotated into the lifting device and the adapter hole. At the same time, when installing the fixing rod, the limit pin is rotated into the fixing rod and the adapter hole. By setting the entire device, the support pier can be easily lifted and transported, reducing the waste of manpower and avoiding the situation of the support pier being dropped and damaged.

[0014] 2. When the entire device does not need to be moved, this utility model rotates the threaded rod, causing it to rotate on the inner surface of the placement plate and the inner wall of the threaded hole of the moving block. The threaded rod drives the moving block to move, and the moving block drives the brake pad to move. The brake pad presses against the surface of the support wheel, and when the placement plate is under force, the force is distributed to the support bar. By setting up the entire device, the entire device can be stopped, reducing the situation where the device moves randomly on the roof and affects construction, and also reducing the possibility of the device moving randomly and endangering construction personnel.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, a rooftop photovoltaic support trolley includes a support frame 1 and a lifting device 4. Support wheels 2 are rotatably connected to both sides of the support frame 1. A support rod 3 is fixedly connected to the upper surface of the support frame 1, and the lifting device 4 is fixedly connected to the bottom end of the support rod 3. A hook 5 is fixedly connected to the bottom end of the lifting device 4. During operation, pushing the support rod 3 causes the support frame 1 to move, which in turn causes the support wheels 2 to roll on the roof. The support trolley is then hung on the hook 5. Pressing down the support rod 3 causes the lifting device 4 and hook 5 to rise, which in turn causes the support trolley to move. Pushing the support rod 3 again causes the support wheels 2 to roll. By using the support frame 1, support wheels 2, support rod 3, lifting device 4, and hook 5, the support trolley can be easily moved, thus facilitating its installation.

[0024] Two support rods 6 are fixedly connected to the surface of the support frame 1, and the two support rods 6 are symmetrically distributed with respect to the central axis of the support frame 1. During operation, the support frame 1 will transmit force to the support rods 6, and the support rods 6 can increase the strength of the support frame 1.

[0025] The support rod 3 and the support frame 1 are fixedly connected to the surface of the fixed rod 7; during operation, the force is transmitted to the fixed rod 7, which can increase the strength of the support rod 3 and the support frame 1.

[0026] A storage block 8 is fixedly connected to the upper surface of the support frame 1, and the inner wall of the storage block 8 is slidably connected to the surface of the support rod 3. During operation, the support rod 3 slides on the inner wall of the storage block 8, and the storage block 8 can bear the pressure at the connection between the support frame 1 and the support rod 3.

[0027] The bottom end of the support rod 3 is provided with multiple adapter holes 9. Bolts are provided on the inner walls of the adapter holes 9 of the support frame 1 and the support rod 3. Two positioning pins are provided on the inner walls of the adapter holes 9 of the support rod 3 and the inner walls of the lifting device 4. Limiting pins are provided on the inner walls of the adapter holes 9 of the support rod 3, the inner walls of the support frame 1 and the inner walls of the fixing rod 7. During operation, the adapter holes 9 allow the support rod 3 to be fixed at different positions on the support frame 1, and the lifting device 4 and the fixing rod 7 can also be installed on the support rod 3.

[0028] The support rod 6 is provided with a limiting device 10, which includes a placement plate 101. The side wall of the placement plate 101 is fixedly connected to the surface of the support rod 6. A threaded rod 102 is rotatably connected to the inner surface of the placement plate 101. The surface of the threaded rod 102 is provided with two opposite thread lines. Two moving blocks 103 are threadedly connected to the surface of the threaded rod 102. A brake pad 104 is fixedly connected to the side wall of the moving block 103. The brake pad 104 is located on one side of the support wheel 2. During operation, rotating the threaded rod 102 causes it to rotate on the inner surface of the placement plate 101 and the inner walls of the two moving blocks 103. The moving blocks 103 drive the brake pad 104 to move, and the brake pad 104 presses against the surface of the support wheel 2. By setting up the placement plate 101, the threaded rod 102, the moving blocks 103, and the brake pad 104, the rotation of the support wheel 2 can be restricted, thereby achieving a braking effect.

[0029] Two support bars 105 are fixedly connected to the side wall of the placement plate 101 and the surface of the support rod 6. The surface of the moving block 103 is provided with a threaded hole 106. The inner wall of the threaded hole 106 of the moving block 103 is threadedly connected to the surface of the threaded rod 102. During operation, the placement plate 101 transmits force to the support bars 105. When the threaded rod 102 rotates, the threaded rod 102 rotates on the inner wall of the threaded hole 106. The opening of the threaded hole 106 facilitates the rotation of the threaded rod 102 on the inner wall of the moving block 103.

[0030] Working principle: When the support pier needs to be installed, push the support rod 3 to move the support frame 1 and the lifting device 4. When the support frame 1 moves, it will cause the support wheel 2 to roll on the roof. After the lifting device 4 moves to the appropriate position, hang the support pier on the hook 5. Then press down the support rod 3 to lift the lifting device 4, hook 5 and support pier. Then push the support rod 3 to move the support pier to the installation position. When the support rod 3 is under force, it will transmit the force to the storage block 8, the fixing rod 7 and the support rod 6. When installing the support rod 3, rotate the bolt into the inner wall of the support frame 1 and the adapter hole 9. When installing the lifting device 4, rotate the positioning pin into the lifting device 4 and the adapter hole 9. At the same time, when installing the fixing rod 7, rotate the limit pin into the fixing rod. Within holes 7 and 9, the entire device facilitates the hoisting of the support piers, reducing manpower waste and preventing them from slipping and breaking. When the entire device does not need to be moved, rotating the threaded rod 102 causes it to rotate on the inner surface of the placement plate 101 and the inner wall of the threaded hole 106 of the moving block 103. The threaded rod 102 drives the moving block 103 to move, which in turn moves the brake pad 104. The brake pad 104 presses against the surface of the support wheel 2, distributing the force to the support bar 105 when the placement plate 101 is under stress. By setting up the entire device, the entire device can be stopped, reducing the possibility of the device moving around on the roof and affecting construction, as well as reducing the possibility of the device moving around and endangering construction workers.
