Description

Technical Field

[0001] This application relates to the field of photovoltaic installation technology, and in particular to a concrete counterweight lifting device based on photovoltaic installation. Background Technology

[0002] A concrete counterweight lifting device for photovoltaic (PV) systems is a piece of equipment used for installing PV power plants. It typically consists of a hydraulic system, a support frame, and counterweights. Its function is to use the hydraulic system to lift the concrete counterweights to the required height, and then install the counterweights onto the PV support frame to increase the frame's stability and load-bearing capacity. This device helps PV power plants complete installation quickly and safely, improving the stability and safety of the PV system.

[0003] A published patent document with announcement number CN214900734U discloses a photovoltaic support lifting mechanism, including a support lifting machine mounted on a support base. The top of the support lifting machine is detachably connected to the photovoltaic support. The support lifting machine includes a transmission mechanism with a self-locking function and a stroke mechanism connected to the transmission mechanism. When the transmission mechanism is activated, the support lifting machine is used to lift the photovoltaic support to a predetermined height. However, this structure is not easy to adjust the angle of the workpiece during the lifting process, making it inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a concrete counterweight lifting device based on photovoltaic technology, which overcomes the deficiencies of existing technologies and aims to solve the problem that existing photovoltaic lifting devices are not easy to adjust the angle of the workpiece during the lifting process, resulting in inconvenience in use.

[0005] To achieve the above objectives, this application provides the following technical solution: a concrete counterweight lifting device based on photovoltaic construction, comprising a base, a gantry frame fixedly installed on one side of the upper surface of the base, a vertical rod fixedly installed inside the gantry frame, a lifting plate slidably sleeved on the outer surface of the vertical rod, an electric hydraulic push rod fixedly connected to the bottom of the lifting plate, the electric hydraulic push rod fixedly installed on the top of the base, a movable groove penetrating the upper surface of the lifting plate away from the gantry frame, a hopper provided inside the movable groove, rotating shafts symmetrically connected to the outer walls of the hopper on both sides, the rotating shafts rotatably installed inside the lifting plate, the hopper being movably connected to the lifting plate through the rotating shafts, a toothed ring fixedly connected to the outer wall of the hopper on one side of the rotating shaft, and a drive unit for driving the toothed ring to rotate fixedly installed on the side wall of the lifting plate.

[0006] By adopting the above technical solution, the lifting plate is driven to slide up and down along the vertical rod by an electro-hydraulic push rod to complete the vertical lifting action. The gantry frame and the vertical rod cooperate to provide rigid support and ensure the movement stability of the lifting plate. The hopper is rotatably connected to the lifting plate through a rotating shaft to achieve free rotation. The drive unit controls the rotation angle of the hopper by driving the meshing gear ring to rotate and adjust the tilt angle of the hopper to facilitate the workers to pick up the material. In other words, this lifting device can adjust the lifting height and tilt angle of the hopper synchronously by working in conjunction with the electro-hydraulic push rod and the drive unit to adapt to different working conditions.

[0007] As a preferred technical solution of this application, the drive unit includes a drive motor fixedly installed on the side wall of the lifting plate, and a gear is fixedly connected to the output end of the drive motor. The gear and the gear ring are on the same vertical plane and mesh with each other.

[0008] By adopting the above technical solution, the gear is driven to rotate by the drive motor. Since the gear meshes with the gear ring, the gear ring can rotate under the driving action of the drive motor.

[0009] As a preferred technical solution of this application, the side wall of the lifting plate is provided with an arc-shaped groove on the outer side of the toothed ring, and a limiting block is slidably connected inside the arc-shaped groove, and the limiting block is fixedly installed on the outer wall of the toothed ring.

[0010] By adopting the above technical solution, the limiting block slides along the arc groove, restricting the rotational movement of the toothed ring within the preset arc path, preventing the hopper from rotating beyond its range. When the limiting block slides to both ends of the arc groove, it forms a rigid limit by contacting the groove wall, thus avoiding overload operation of the drive unit and structural damage.

[0011] As a preferred technical solution of this application, the center of the toothed ring and the center of the arc groove are on the same central axis, and the outer diameter of the limiting block is adapted to the inner diameter of the arc groove.

[0012] By adopting the above technical solution, the trajectory of the arc groove is matched with the motion trajectory of the toothed ring, ensuring that the tilt angle of the hopper and the output of the drive motor maintain a precise correspondence. The outer diameter of the limit block and the inner diameter of the arc groove are matched to form a constraint relationship, preventing the limit block from shifting position during movement.

[0013] As a preferred technical solution of this application, a sleeve is fixedly connected to the lower surface of the lifting plate, the sleeve is slidably sleeved on the outer wall of the vertical rod, and a support rod is fixedly connected between the sleeve and the lifting plate.

[0014] By adopting the above technical solution, the sleeve and the vertical rod slide together to form a precision guide, which can reduce the radial offset when the lifting plate moves vertically and ensure the accuracy of the lifting trajectory. The support rod connects the sleeve and the lifting plate at an inclined angle to form a triangular stable structure, which supports and reinforces the lifting plate and prevents the lifting plate from bending and deforming due to eccentric load.

[0015] As a preferred technical solution of this application, the bottom of the base is fixedly equipped with four locking casters that are evenly distributed in a linear array.

[0016] By adopting the above technical solution and setting locking casters to allow the device to move in any direction, the position of the device can be quickly adjusted to adapt to the complex terrain of the photovoltaic construction site.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, an electric hydraulic push rod drives a lifting plate to slide up and down along a vertical rod, completing the vertical lifting action. The gantry frame and the vertical rod work together to provide rigid support, ensuring the stability of the lifting plate's movement. The hopper is rotatably connected to the lifting plate via a rotating shaft, allowing for free rotation. The drive unit controls the hopper's rotation angle by driving the meshing gear ring to rotate, adjusting the hopper's tilt angle to facilitate material retrieval by workers. In other words, this lifting device, through the coordinated work of the electric hydraulic push rod and the drive unit, can synchronously adjust the hopper's lifting height and tilt angle to adapt to different working conditions.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a photovoltaic-based concrete counterweight lifting device, including a base 1. A gantry frame 5 is fixedly installed on one side of the upper surface of the base 1. A vertical rod 4 is fixedly installed inside the gantry frame 5. A lifting plate 3 is slidably sleeved on the outer surface of the vertical rod 4. An electric hydraulic push rod 2 is fixedly connected to the bottom of the lifting plate 3. The electric hydraulic push rod 2 is fixedly installed on the top of the base 1. A movable groove 6 is opened through the upper surface of the lifting plate 3 on the side away from the gantry frame 5. A hopper 7 is arranged inside the movable groove 6. Rotating shafts 8 are symmetrically connected to the outer walls of both sides of the hopper 7. The rotating shafts 8 are rotatably installed inside the lifting plate 3. The hopper 7 is movably connected to the lifting plate 3 through the rotating shafts 8. The outer wall of the hopper 7 is located on one side of the rotating shaft 8. A gear ring 9 is fixedly connected, and a drive unit 12 for driving the gear ring 9 to rotate is fixedly installed on the side wall of the lifting plate 3. In use, the lifting plate 3 is driven to slide up and down along the vertical rod 4 by the electric hydraulic push rod 2 to complete the vertical lifting action. The gantry frame 5 and the vertical rod 4 cooperate to provide rigid support to ensure the movement stability of the lifting plate 3. The hopper 7 is rotatably connected to the lifting plate 3 through the rotating shaft 8 to achieve free rotation. The drive unit 12 controls the rotation angle of the hopper 7 by driving the meshing gear ring 9 to rotate, and adjusts the tilt angle of the hopper 7 to facilitate the workers to pick up materials. That is, the lifting device can adjust the lifting height and tilt angle of the hopper 7 synchronously by working in conjunction with the electric hydraulic push rod 2 and the drive unit 12 to adapt to different working conditions.

[0028] In this embodiment, as Figure 3 and 4 As shown, the drive unit 12 includes a drive motor 121 fixedly installed on the side wall of the lifting plate 3. A gear 122 is fixedly connected to the output end of the drive motor 121. The gear 122 and the gear ring 9 are on the same vertical plane and mesh with each other. In use, the drive motor 121 drives the gear 122 to rotate. Since the gear 122 meshes with the gear ring 9, the gear ring 9 can rotate under the driving action of the drive motor 121.

[0029] In this embodiment, as Figure 2 and 3 As shown, the side wall of the lifting plate 3 is provided with an arc-shaped groove 11 on the outside of the toothed ring 9. The inside of the arc-shaped groove 11 is slidably connected to a limiting block 10. The limiting block 10 is fixedly installed on the outer wall of the toothed ring 9. In use, the limiting block 10 slides along the arc-shaped groove 11 to limit the rotational movement of the toothed ring 9 within a preset arc-shaped path, preventing the hopper 7 from rotating beyond its range. When the limiting block 10 slides to both ends of the arc-shaped groove 11, it forms a rigid limit by contacting the groove wall, thus avoiding overload operation of the drive unit 12 and structural damage.

[0030] In this embodiment, as Figure 2 and 3 As shown, the center of the toothed ring 9 and the center of the arc groove 11 are on the same central axis, and the outer diameter of the limiting block 10 is adapted to the inner diameter of the arc groove 11. In use, the trajectory of the arc groove 11 matches the movement trajectory of the toothed ring 9, ensuring that the tilt angle of the hopper 7 and the output of the drive motor 121 maintain a precise correspondence. The outer diameter of the limiting block 10 and the inner diameter of the arc groove 11 are adapted to form a constraint relationship, preventing the limiting block 10 from shifting position during movement.

[0031] In this embodiment, as Figure 1 and 3 As shown, a sleeve 13 is fixedly connected to the lower surface of the lifting plate 3. The sleeve 13 is slidably sleeved on the outer wall of the vertical rod 4, and a support rod 14 is fixedly connected between the sleeve 13 and the lifting plate 3. In use, the sleeve 13 and the vertical rod 4 slide together to form a precision guide, which can reduce the radial offset when the lifting plate 3 moves vertically and ensure the accuracy of the lifting trajectory. The support rod 14 connects the sleeve 13 and the lifting plate 3 at an inclined angle to form a triangular stable structure, which supports and reinforces the lifting plate 3 and prevents the lifting plate 3 from bending and deforming due to eccentric load.

[0032] In this embodiment, as Figure 1 As shown, four locking casters 15 are fixedly installed at the bottom of the base 1 in a linear array. In use, the locking casters 15 allow the device to move in any direction, and the position of the device can be quickly adjusted to adapt to the complex terrain of the photovoltaic construction site.

[0033] The working principle of this utility model is as follows: When using the concrete counterweight lifting device based on photovoltaic construction according to this application, the worker first places the concrete counterweight inside the hopper 7, and drives the lifting plate 3 to slide up and down along the vertical rod 4 through the electric hydraulic push rod 2 to complete the vertical lifting action and raise the hopper 7 to the designated position. Then, the drive motor 121 drives the gear 122 to rotate and drive the gear ring 9 to rotate, so that the hopper 7 rotates around the rotating shaft 8, which can adjust the tilt angle of the hopper 7, making it convenient for the worker to pick up the material.
