Description

Technical Field

[0001] The utility model relates to a lifting device, in particular to a device for preventing photovoltaic components from falling over and lifting them when unpacking. Background Art

[0002] The structure of photovoltaic modules mainly includes glass panels, back panels, frames, back panels, cells and connecting wires. The panels of photovoltaic modules are tempered glass, which is easy to break or crack. After the modules arrive, they need to be unpacked and visually inspected piece by piece. The module packaging is generally paper packaging. Taking the monocrystalline double-sided double-glass 550W battery module as an example, there are more than 30 pieces per box. The packaging size is generally about 2300mm long, 1100mm wide, and 1250mm high. The weight of a single box is about 1T. The size of a single module is 227mm8 long, 1134mm wide, and 30mm thick. The module is fixed on a wooden pallet like a book standing sideways.

[0003] Component manufacturers generally provide unpacking brackets and lifting devices, which are independent structures. Among them, the unpacking bracket is narrow in width, and the components fit tightly to the bracket after unpacking, without expanding the chassis space. When unpacking, 1~2 components at both ends need to be removed manually to have space to tilt the components and check whether there are any abnormalities on the front and back sides; the components can only be tilted to one side and can only be counted in one direction, which is inefficient. The lifting device is large in size and weight, not easy to carry, and has a single function. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a device for preventing photovoltaic components from falling over and lifting when unpacking, which can facilitate the early lifting and later counting of photovoltaic components.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A device for preventing photovoltaic components from falling over and for lifting when unpacking, comprising a left bracket and a right bracket, wherein the bottom ends of the left bracket and the right bracket are both hinged with a base with holes, and the left and right bases are connected by connecting rods to form a whole; the top ends of the left bracket and the right bracket are both hinged with lifting arms, and the left and right lifting arms are directly opposite and connected by pins to form a whole.

[0007] The left bracket and the right bracket both include supports, which are in an inverted V shape and are connected and reinforced by a cross brace in the middle.

[0008] A lifting ring is arranged on the lifting arm.

[0009] A rubber plate is fixed on one side of the upper end surface of the base close to the hinge point.

[0010] The pin is connected with the left bracket or the right bracket through an endless chain.

[0011] The utility model provides a device for preventing photovoltaic modules from falling over and lifting during unpacking, which has the following technical effects:

[0012] 1) By rotating the lifting arm, the lifting and unpacking anti-falling requirements are met at the same time, which is in line with the on-site installation process of photovoltaic modules. The left bracket and the right bracket can be used together or used separately as anti-falling brackets. When the two are used as anti-falling brackets, the components can be divided into two groups and fall onto the left bracket and the right bracket on both sides, so that both sides can be counted to improve efficiency.

[0013] 2) The base is made of welded steel plates, with a long contact surface with the ground and good stability. The contact surface with the bottom of the pallet is flat, which reduces the deformation of the bottom of the pallet during lifting.

[0014] 3) In addition, a 10mm thick rubber plate is added to the base. When unpacking, move the components on both sides to the rubber plate first, so that the components have space to tilt, which is efficient. There is no need to lift the components on both sides to the side first as in traditional operations.

[0015] 4) The latch fixing holes on the lifting arm can be positioned in multiple locations according to the size of the component packaging. The ring chain is both an anti-lost connector for the latch and a locking chain. When the bracket is used as an unpacking anti-fall bracket, the latch can be inserted into different holes on the lifting arm, and the inclination of the support can be adjusted to adapt to uneven stacking sites such as slopes.

[0021] like Figure 1-2As shown, a device for preventing photovoltaic modules from falling over and lifting during unpacking includes a left bracket and a right bracket. The left bracket and the right bracket have the same structure and both include a support 2. The support 2 is an inverted V-shaped support and is connected and reinforced in the middle by a cross brace 3. A base 5 is hinged on the two legs at the lower end of the support 2. A through hole is horizontally provided on the base 5. When the left bracket and the right bracket are arranged relative to each other on the left and right sides, the connecting rod 11 can pass through the through hole of the base 5 on the left bracket and the right bracket, so that the lower ends of the left bracket and the right bracket form a whole. A lifting arm 6 is hinged on the upper end of the support 2. A lifting ring is provided at a suitable position on the lifting arm 6. The lifting ring is used for the wire rope hook to pass through during lifting. In addition, each lifting arm 6 is provided with five groups of connecting holes. When the two lifting arms 6 of the left bracket and the right bracket are horizontal, the pin 9 (with an anti-falling plug-in at the front end) can be inserted into the connecting holes of the two lifting arms 6, so that the two can be horizontally connected, which is convenient for later lifting.

[0022] Preferably, a chain 10 is connected to the cross brace 3, and the chain 10 is connected to the pin 9. This can prevent the pin 9 from being lost, and the device can also be locked when it is deployed later.

[0023] Working principle and process:

[0024] 1) If Figure 1 As shown, when used for lifting, the component package 1 (the photovoltaic component has a paper packaging box outside) is located between the left bracket and the right bracket, and two universal scaffolding steel pipes with a diameter of 48 mm are passed through the through hole of the base 5 and the gap of the tray 4 (the component package 1 is placed on the tray 4).

[0025] 2) The lifting arms 6 of the left and right brackets are turned upward to a horizontal position, the connection holes on the two lifting arms 6 correspond, the pins 9 are inserted into the connection holes and locked, and the pins 9 are fixed to the cross brace 3 through the ring chain 10. The lifting wire rope and the hook 7 are connected to the lifting ring on the lifting arm 6 to complete the lifting operation. The base 5 of the device limits the support rotation angle to ensure that the component package 1 will not be squeezed during lifting.

[0026] 3) If Figure 2 As shown, when the component package 1 is lifted to the storage location on the construction site, the wire rope is removed, the pin 9 is pulled out, the lifting arm 6 is flipped over to form a tripod with the support 2, and the pin 9 connected to the ring chain 10 is inserted into the hole of the lifting arm 6 at an appropriate height to stabilize and fix the tripod.
