Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a transportation device for transferring photovoltaic modules on a roof. Background Technology

[0002] Photovoltaic power generation, with its significant advantages such as being green and low-carbon, economical and efficient, and flexible in its application, is becoming an important technological path for promoting the clean energy transition. To improve the efficiency of solar energy absorption, photovoltaic modules are generally installed on rooftops. However, due to the large size and weight of common photovoltaic modules, coupled with their brittle and hard materials, rooftop installation typically involves hoisting the panels to the designated location on the roof, followed by manual disassembly and relocation, and finally installation. This transportation method is time-consuming, labor-intensive, inefficient, and prone to damaging the photovoltaic panels.

[0003] In existing technologies, although photovoltaic panels can be transported by setting up sliding rails and railcars on the roof structure, setting up sliding rails separately on the roof increases the construction period and difficulty. At the same time, the roof is generally a sloping surface, and the existing railcars lack consideration for limiting and guiding the photovoltaic panels during the sliding process, which poses a safety hazard of the photovoltaic panels slipping off the railcar or the railcar derailing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a transportation device for transferring photovoltaic modules on a roof. By designing a sliding trolley and using the purlins conventionally installed on the roof steel structure as slide rails, the photovoltaic panels can be transferred. At the same time, the sliding trolley is also equipped with a first limiting structure for sliding and guiding and a second limiting structure for limiting the photovoltaic panels, which helps to improve construction efficiency, ensure construction quality and guarantee construction safety.

[0005] This utility model provides a transportation device for transferring photovoltaic modules on a roof, including a device body that is slidably mounted on a steel purlin of the roof structure. The bottom surface of the device body is provided with a first limiting structure at both ends perpendicular to the sliding direction for sliding and limiting guidance in cooperation with the purlin.

[0006] Furthermore, the top surface of the device body is provided with a second limiting structure at the end located at the lowest position in the vertical direction for limiting the position of the photovoltaic module.

[0007] Furthermore, it also includes a sliding member disposed on the bottom surface of the device body and slidingly engaged with the purlin, wherein at least two sets of the sliding member are disposed at both ends of the bottom surface of the device body perpendicular to the sliding direction.

[0008] Furthermore, the first limiting structure is respectively disposed on the outside of the slider and cooperates with the purlin in a limiting manner perpendicular to the sliding direction.

[0009] Furthermore, the device body is provided with traction parts for sliding traction at both the front and rear ends located in the sliding direction.

[0010] Furthermore, the device body includes at least two sets of horizontal bar assemblies arranged perpendicular to the sliding direction and at least two sets of vertical bar assemblies arranged parallel to the sliding direction. The horizontal bar assemblies and the vertical bar assemblies are interlocked and fixed to form a frame structure.

[0011] The present invention has the following beneficial effects: The transportation device of the present invention effectively avoids the risks of high-altitude operations on rooftops and reduces construction safety hazards by using mechanical transportation to replace traditional manual handling of photovoltaic modules, thus ensuring the safety of workers; it makes full use of the purlins on the fixed brackets of the rooftop photovoltaic modules as running tracks, eliminating the need to lay separate construction and transportation channels and saving templates; at the same time, the sliding trolley is also equipped with a first limiting structure for sliding and guiding and a second limiting structure for limiting the photovoltaic panels, which helps to improve construction efficiency, ensure construction quality, and guarantee construction safety.

[0015] This application proposes a transportation device for transporting photovoltaic modules on a roof, comprising a device body slidably mounted on the purlins of the roof steel structure. The bottom surface of the device body has first limiting structures at both ends perpendicular to the sliding direction for sliding and guiding in conjunction with the purlins. When photovoltaic modules are installed on a roof, a steel structure is typically installed for support. This steel structure generally includes fixed supports and purlins horizontally mounted on the fixed supports; this is prior art and will not be elaborated upon here. However, in this application, the device body utilizes the purlins as sliding tracks to transport photovoltaic modules on the roof, eliminating the need for additional construction work. The device saves templates by using a conveying channel. The sliding direction specifically refers to the horizontal direction on the sloping roof. Since the roof is sloping, the device body is prone to slippage due to gravity during sliding. To ensure the stability and safety of the device body during transport on the purlins, the bottom surface of the device body is equipped with a first limiting structure at both ends perpendicular to the sliding direction. This first limiting structure cooperates with the purlins to limit and guide the sliding movement. Through the cooperation of the first limiting structure and the sliding limiting and guiding of the purlins, the device body will not derail or overturn in the direction perpendicular to the sliding direction. The first limiting structure can be a limiting ring or a limiting rod, depending on the practical application.

[0016] In this embodiment, the top surface of the device body is provided with a second limiting structure for limiting the position of the photovoltaic module at the end located at the lowest position in the vertical direction; combined with Figure 1 As shown, the top surface of the second limiting structure setting device body is located at the lowest vertical position. Since the roof is an inclined surface, the photovoltaic modules loaded on the device body are prone to slip off the device body due to gravity during transportation. Therefore, a second limiting structure is set at the lowest vertical position on the top surface of the device body to ensure the limiting of the photovoltaic modules on the device body. In this solution, the second limiting structure is the third limiting component 5, specifically a limiting rod structure.

[0017] In this embodiment, a sliding member is also included, which is disposed on the bottom surface of the device body and slides in cooperation with the purlin. At least two sets of the sliding member are provided at both ends of the bottom surface of the device body perpendicular to the sliding direction. Figure 1 As shown, the sliding component is a sliding wheel 4, and the sliding wheel 4 in this solution has a built-in braking function so that the device body can be parked at the target position on the roof. This is existing technology and will not be described in detail here. Since the roof is a sloping surface, at least two sets of sliding wheels 4 need to be arranged opposite each other at both ends of the bottom surface of the device body perpendicular to the sliding direction to ensure the sliding stability of the device body. At the same time, when arranging the two sets of sliding wheels 4 on the bottom surface of the device body, the spacing between adjacent purlins of the roof needs to be considered to ensure the sliding cooperation between the sliding wheel 4 and the purlin.

[0018] In this embodiment, the first limiting structure is respectively disposed on the outside of the sliding member and cooperates with the purlin in a limiting manner perpendicular to the sliding direction; combined with Figure 1 As shown, the first limiting structure includes a first limiting member 6 and a second limiting member 7. Both the first limiting member 6 and the second limiting member 7 are connected and fixed to the device body and act downward on the side wall of the purlin. The first limiting member 6 and the second limiting member 7 are respectively located on the outer side of the sliding member, so that when the device body slides on the roof, it can limit the device body to the adjacent purlin. At the same time, it also has the function of guiding the sliding of the device body. In this solution, the first limiting member 6 is specifically a limiting rod and the second limiting member 7 is a limiting ring.

[0019] In this embodiment, the device body is further provided with traction parts 8 for sliding traction at both the front and rear ends located in the sliding direction; combined with Figure 1 As shown, traction units 8 for sliding traction are respectively provided at the front and rear ends of the device body in the sliding direction. The traction units 8 can be connected to traction ropes, which can be manually pulled or mechanically pulled by an electric motor to provide sliding traction force for the device body.

[0020] In this embodiment, the device body includes at least two sets of horizontal bar assemblies 1 arranged perpendicular to the sliding direction and at least two sets of vertical bar assemblies 2 arranged parallel to the sliding direction. The horizontal bar assemblies 1 and the vertical bar assemblies 2 are interlocked and fixed to form a frame structure. Figure 1 As shown, the main body of the device is formed by the overlapping and fixing of horizontal bar assembly 1 and vertical bar assembly 2 to form a frame structure. The specific structural shape of the main body of the device is determined according to the application. In this scheme, there are two sets of horizontal bar assembly 1 and three sets of vertical bar assembly 2. After overlapping, they form a H-shaped frame structure. Two sets of vertical bar assembly 2 use hot-dip galvanized rectangular tubes, and one set uses L-shaped angle steel 3. Both sets of horizontal bar assembly 1 use hot-dip galvanized rectangular tubes. Due to the influence of the roof steel structure purlins, sliding wheels 4 are respectively set on the vertical bar assembly 2 of the hot-dip galvanized rectangular tubes to ensure connection stability. At the same time, the first limiting piece 6 and the second limiting piece 7 are welded to the sides of the vertical bar assembly 2 of the two sets of hot-dip galvanized rectangular tubes. The vertical bar assembly 2 of L-shaped angle steel 3 is set at the end of the main body of the device at the lowest position in the vertical direction, and the third limiting piece is arranged on the vertical bar assembly 2 of L-shaped angle steel 3 to limit the photovoltaic module.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
