Technical Field

[0001] The utility model relates to the technical field of photovoltaic construction, in particular to a hoisting device for photovoltaic construction. Background Art

[0002] To ensure the best lighting effect, photovoltaic panels are usually installed at high places on buildings and need to be lifted by hoisting equipment during construction.

[0003] The current traditional lifting device, such as the announcement number CN215942968U, is named a multifunctional suction cup robot arm, which relates to the field of robot arm technology and includes a shell. The shell is a hollow rectangular structure. A clamping mechanism is installed inside the shell. The top of the shell is connected to the robot arm through a connecting frame. The bottom of the shell is fixed with a support plate. Both ends of the support plate are equipped with a second hydraulic cylinder. The piston rod of the second hydraulic cylinder passes through the support plate and is connected to a mounting plate. A vacuum suction cup is installed on the mounting plate. Compared with the existing technology, the utility model drives the mounting plate and the vacuum suction cup to rise and fall by setting a second hydraulic cylinder, which makes it easier for the vacuum suction cup to grab materials and improves the convenience of grabbing. At the same time, a clamping mechanism is used to assist the vacuum suction cup in picking up materials.

[0004] However, in order to ensure the stability of lifting, the existing lifting device has a relatively complicated structural design and high energy consumption; therefore, we propose a lifting device for photovoltaic construction to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a hoisting device for photovoltaic construction, so as to solve the problems of the existing hoisting device proposed in the above background technology that the structural design is relatively complicated and the energy consumption is high in order to ensure the stability of hoisting.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting device for photovoltaic construction, comprising a base, a column is installed on the upper end of the base, a balancing lifting mechanism is installed on the upper end of the column, a lifting arm is installed at the front end of the balancing lifting mechanism, a connecting arm is installed at the front end of the lifting arm, a lifting arm is installed at the front end of the connecting arm, a lifting ring is installed at one end of the lifting arm, a scissors-type clamping mechanism is installed below the lifting ring, the lifting ring is connected to the four corners of the scissors-type clamping mechanism through a lifting rope, a support platform is installed inside the lifting ring, hydraulic cylinders are installed inside both sides of the support platform, an auxiliary stabilizing block is installed on the output end of the hydraulic cylinder, an auxiliary positioning structure is provided on the lower surface of the auxiliary stabilizing block, and a triangular reinforcement plate is welded at the connection between the column and the base, and four triangular reinforcement plates are provided.

[0007] Preferably, the auxiliary positioning structure on the lower surface of the auxiliary stabilizing block is a rubber pressure pad.

[0008] Preferably, the auxiliary positioning structure on the lower surface of the auxiliary stabilizing block is a vacuum suction cup, a plurality of vacuum suction cups are provided, and a vacuum joint is provided at the front end of the auxiliary stabilizing block.

[0009] Preferably, the scissors-type clamping mechanism includes a first scissors arm and a second scissors arm, two of each of the first scissors arm and the second scissors arm are provided, the two second scissors arms are respectively provided on the inner sides of the two first scissors arms, and the first scissors arm and the second scissors arm are provided opposite to each other, the first scissors arm and the second scissors arm are rotatably connected at the middle position through a central rotating shaft, and the two first scissors arms and the second scissors arms are connected by a reinforcing connecting rod.

[0010] Preferably, an L-shaped clamping block is installed on the inner side of one end of the first scissor arm and the second scissor arm, a rubber block is installed on the inner wall of the L-shaped clamping block, and an anti-slip pattern is provided on the outer wall of the rubber block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adopts a scissor-type clamping mechanism to clamp and lift the photovoltaic panel. The scissor-type clamping mechanism includes a first scissor arm and a second scissor arm. Two of the first scissor arm and the second scissor arm are provided. The two second scissor arms are respectively provided on the inner sides of the two first scissor arms, and the first scissor arm and the second scissor arm are provided opposite to each other. The middle position of the first scissor arm and the second scissor arm is rotatably connected by a central rotating shaft. The two first scissor arms and the second scissor arms are connected by a reinforced connecting rod. The other ends of the first scissor arm and the second scissor arm are connected to the lifting ring by a lifting rope. When the boom is raised, it can pull The lifting rope drives the first scissor arm and the second scissor arm to rotate along the central axis, and the scissor motion of the first scissor arm and the second scissor arm is used to clamp the photovoltaic panel. After the scissor-type clamping mechanism clamps and positions the photovoltaic panel, the hydraulic cylinder can drive the auxiliary stabilizing block to move downward, applying a certain top-down pressure on the photovoltaic panel, so that it can be more tightly connected with the scissor-type clamping mechanism, thereby improving the subsequent lifting stability. To a minimum, only the auxiliary stabilizing block of the entire lifting system requires hydraulic control, and the energy consumption is low, which solves the problem that the existing lifting device has a relatively cumbersome structural design and high energy consumption in order to ensure lifting stability.

[0013] When lifting lightweight photovoltaic panels that are small in size and made of light material, the auxiliary stabilizing block can ensure stability by relying on downward pressure in conjunction with the L-shaped clamping block. The bottom surface can be directly set as a rubber pressure pad to avoid wear on the photovoltaic panel surface during pressing.

[0014] When lifting large-sized and heavy photovoltaic panels, the lifting mechanism can be equipped with vacuum equipment and use auxiliary stabilizing blocks with vacuum suction cups. After the scissor-type clamping mechanism clamps the photovoltaic panel, the hydraulic cylinder drives the auxiliary stabilizing block downward, applying a certain top-down pressure on the photovoltaic panel while using the vacuum suction cup to adsorb and reinforce the photovoltaic panel. This structure has a strong windproof function and significantly improves the safety of lifting. BRIEF DESCRIPTION OF THE DRAWINGS
