Description

Technical Field

[0001] The invention relates to the field of transportation of roof photovoltaic components, and in particular to a transportation device and method for roof photovoltaic components. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the prior art, some photovoltaic modules are installed on the roof. During the installation process, the photovoltaic modules need to be transported on the roof. Currently, cranes are mostly used to transport the photovoltaic modules to the roof for centralized stacking. After stacking, the photovoltaic modules are manually transported to bulk materials. The inventors found that the existing methods have the following problems:

[0004] The weight of a single photovoltaic module is about 30kg, and the load-bearing design value does not take into account large concentrated loads, so photovoltaic modules are not allowed to be stacked on the roof. Most existing roofs are inclined structures, and photovoltaic modules are installed along the slope. Especially when the roof area is large, ground cranes or truck cranes are not suitable for long-distance transportation and it is difficult to transport the modules to the internal location.

[0005] Dispersed components require installers to frequently carry photovoltaic components back and forth on the roof, which may cause hidden cracks in the photovoltaic components due to stress during transportation, and deformation caused by stepping on the color steel tile roof. It is labor-intensive, dangerous, and has low construction efficiency, which is not conducive to organizing large-scale construction.

[0006] In addition, the flat transport equipment currently used for installing photovoltaic modules requires the laying of special tracks, which increases the difficulty of on-site construction.

[0007] When installing photovoltaic modules on industrial plants and rural roofs, in order to increase the usable area of ​​the roof, a full-paving solution is usually adopted, leaving no space for laying tracks. Summary of the invention

[0008] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a transportation device for roof photovoltaic components, which can adapt to site conditions, reduce work intensity, and facilitate construction.

The arrangement of the auxiliary support structure is beneficial to improving the structural strength of the H-shaped frame structure.

[0021] In a transport device for rooftop photovoltaic components as described above, pins are respectively provided on the outer sides of the longer sides of the two support members in the H-shaped frame structure, and the pins are fixed to the sides of the support members through supports. A second ring is provided at the pins, and the second ring is used to connect with the first steel wire rope or the second steel wire rope.

[0024] The longitudinal section of the support member is L-shaped to support the photovoltaic module.

[0025] In the above-mentioned transport device for roof photovoltaic components, the first guide mechanism and the third guide mechanism are arranged at a distance from one end of the track, and the second guide mechanism is arranged at a distance from the other end of the track;

[0026] The first guide mechanism, the second guide mechanism and the third guide mechanism are all guide wheels, and the guide wheels are arranged higher than the track, so that the first steel wire rope passing around the first guide mechanism and the second guide mechanism is arranged higher than the photovoltaic assembly at the bracket body;

[0034] The beneficial effects of the present invention are as follows:

[0035] 1) The structure of the transport device in the present invention is reasonably arranged. Driven by the traction mechanism and multiple guide mechanisms, the bracket body can reciprocate along the track direction under the traction of the first steel wire rope and the second steel wire rope. The bracket body is connected to the anti-falling mechanism, and the anti-falling mechanism can pull the bracket body to prevent the bracket body from sliding down from the track or the roof or turning over. In this way, even if the roof is inclined, the bracket body can be ensured to move forward stably on the roof, and the transportation of photovoltaic modules on the roof can be realized. After the lifting equipment transports the photovoltaic modules to the roof, the materials can be quickly dispersed to avoid the concentrated stacking of photovoltaic modules on the roof for a long time;

[0036] The transportation of photovoltaic modules by the bracket vehicle avoids the work of manual walking for long distances on the roof to carry photovoltaic modules, reduces labor intensity and the risk of working at heights; avoids the risk of improper force and trampling of photovoltaic modules due to manual handling, and has good application value.

[0037] 2) The bracket body of the present invention can be used to support multiple photovoltaic modules, effectively improving the transportation efficiency of photovoltaic modules, while reducing the requirements for the bearing capacity of the roof, avoiding problems such as local deformation and leakage of the roof caused by repeated trampling by workers, and also improving the installation efficiency of photovoltaic modules.

[0038] 3) In the present invention, a first guide mechanism and a third guide mechanism are arranged at one end of the track, and a second guide mechanism is arranged at the other end of the track. The first guide mechanism and the second guide mechanism are arranged opposite to each other. By changing the number of guide mechanisms, guide mechanisms of different combinations are connected with corresponding bracket bodies, so that different bracket bodies can be transported along the same track, and multiple rows of photovoltaic modules can be installed on the roof. In this way, continuous operation can be achieved, and the construction is quick, convenient, safe and stable.

[0039] 4) The anti-fall mechanism structure of the present invention is reasonably arranged. The safety anti-fall rope in the anti-fall mechanism is placed at the roof ridge, that is, at a relatively high position. One end of the anti-tipping steel wire rope is put on the safety anti-fall rope, and the other end is connected to the bracket body. During the movement of the bracket body, the anti-tipping steel wire rope tightens the bracket body to prevent the bracket body from sliding down or overturning.

[0040] 5) The present invention utilizes photovoltaic brackets as tracks, making full use of existing photovoltaic brackets for laying photovoltaic modules. The photovoltaic brackets have U-shaped grooves, so there is no need to fix the tracks on the roof, which facilitates construction and avoids damage to the roof caused by track laying and disassembly.

[0041] 6) The bracket body structure of the present invention is reasonably arranged. The two support members in the H-shaped frame structure can form an effective space for accommodating photovoltaic components. The spacing between the two support members is arranged to form gaps on both sides of the H-shaped frame structure to facilitate the staff to hold the photovoltaic components and put them into the bracket body or take them out from the bracket body.

[0042] 7) The auxiliary support structure of the present invention is reasonably arranged, which not only effectively enhances the structural strength of the H-shaped frame structure, but also the distance between the two vertical rods is sufficient to ensure the area of ​​the gap on both sides of the bracket body.

[0066] The traction mechanism 4 is wound with a first steel wire rope 41 and a second steel wire rope 42 having opposite moving directions. One side of the first steel wire rope 41 passes through the first guide mechanism and the second guide mechanism in sequence and is connected to one side of the bracket body. The second steel wire rope 42 passes through the third guide mechanism and is connected to the other side of the bracket body. The traction mechanism pulls the bracket body through the first steel wire rope or the second steel wire rope.

[0067] The guide mechanism 3 is arranged on the roof, the traction mechanism is installed on the ground at the side of the house, and the traction mechanism 4 is in the front direction relative to the photovoltaic module, the ridge direction is upward, and the opposite directions are respectively rearward and downward.

[0068] refer to Figure 2As shown, the bracket body includes an H-shaped frame structure 11, an auxiliary support structure 12, a universal wheel 15, a second set of rings 14, a pin shaft 13, and an anti-fall pull ring 16; the H-shaped frame structure 11 is used to support multiple stacked photovoltaic modules, and can support 3 to 5 groups of photovoltaic modules. Notches are respectively arranged on the opposite sides of the width direction of the H-shaped frame structure to facilitate the stacking and transportation of photovoltaic modules. In order to ensure the structural strength of the H-shaped frame structure, auxiliary support structures are respectively arranged on both sides of the bottom surface thereof; the auxiliary support structure is arranged on the bottom side of the H-shaped frame structure, and the auxiliary support structure is arranged at two locations, and the two auxiliary support structures are arranged in opposite directions.

[0069] Specifically, refer to Figure 3 As shown, the H-shaped frame structure includes two oppositely arranged support members, the two support members are connected by a first cross bar, the support member is U-shaped, and the distance between the support members on both sides is set to facilitate forming corresponding notches on both sides of the H-shaped frame structure, and the longitudinal section of the support member is L-shaped, which can be specifically assembled into a support member by angle steel;

[0070] In this embodiment, the auxiliary support structure is a π-shaped frame structure, and the open end of the π-shaped frame structure is arranged toward the notch direction of the H-shaped frame. The auxiliary support structure specifically includes a second cross bar, and two vertical bars are arranged on the side of the second cross bar toward the notch of the H-shaped frame structure. The length and width of the two vertical bars are the same, and the two vertical bars are set at a distance. The space between the two vertical bars is connected to the notch on the corresponding side to ensure the hollow area of ​​the bracket body at two places; one side of the π-shaped frame structure is arranged beyond the H-shaped frame structure, and the vertical bar in the π-shaped frame structure exceeds the side of the H-shaped frame structure and is connected to the anti-fall mechanism.

[0071] It is easy to understand that the H-shaped frame structure and the auxiliary support structure are both equipped with buffer rubber pads for placing and protecting photovoltaic modules. According to the roof bearing capacity, the bracket body can store and transport 3 to 5 photovoltaic modules at a time. Each photovoltaic module is separated by a rubber pad (or resin material) to facilitate unloading in pieces.

[0072] In order to further enhance the strength of the H-shaped frame structure, an oblique rod is cross-arranged at the center of the first cross rod, and both ends of the oblique rod are respectively connected to the support members on the same side.

[0073] In addition, ribs may be added around the support to increase the number of photovoltaic modules that can be transported, thereby further improving work efficiency.

[0074] It is easy to understand that reference Figure 3 As shown, the horizontal section of the longer side of the H-shaped frame structure support is provided with two groups of first long holes 111, which can adjust the spacing between the auxiliary support structures on both sides, thereby adjusting the track span of the bracket body to adapt to the design spacing of the roof photovoltaic bracket; the horizontal section of the shorter side of the H-shaped frame structure support is respectively provided with multiple second long holes 112.

[0075] Specifically, refer to Figure 4 As shown, first bolt holes 121 are respectively provided on both sides of the second cross bar in the auxiliary support structure for connection with the first long hole 111, and the second cross bar is also provided with a third long hole 123 on the inner side of the first bolt hole for connection with the universal wheel 15; a fourth long hole 122 is provided on the side of the vertical rod away from the second cross bar in the auxiliary support structure for connection with the second long hole 112 in the H-shaped frame structure.

[0076] It should be noted that a pin shaft 13 is respectively provided on the outer side of the longer side of the two support members in the H-shaped frame structure, and the pin shaft is fixed to the side of the support member through a support. A second ring 14 is provided at the pin shaft 13, and the second ring 14 is used to connect with the first steel wire rope or the second steel wire rope. The first steel wire rope and the second steel wire rope are fixed on the front and rear sides of the H-shaped frame structure to drag the bracket body from two directions.

[0077] In addition, two anti-fall pull rings 16 are provided on one side of the H-shaped frame structure facing the ridge and on the other side away from the ridge, and the two anti-fall pull rings 16 are located on both sides of the notch of the H-shaped frame structure; the vertical rod in the auxiliary supporting structure can be a U-shaped structural member, and a fixing plate is provided on its side, and the fixing plate is fixedly connected to the anti-fall pull ring 16; or in other examples, the vertical rod in the auxiliary supporting structure is a frame-type structural member, and the anti-fall pull ring 16 is fixed at the end of the frame-type structural member.

[0078] refer to Figure 5 As shown, the universal wheel 15 includes a mounting seat 151 , and the mounting seat 151 is provided with a fifth elongated hole 152 . The fifth elongated hole 152 is used to connect with the third elongated hole 123 . The mounting seat 151 supports a rotatable wheel 153 .

[0079] In this embodiment, the tread and rim of the universal wheel are made of nylon, which has the characteristics of high extrusion strength and good wear resistance. It can play a role in buffering and shock absorption and guiding along the track during the walking process. It is very safe and stable, and greatly reduces the risk of defects such as hidden cracks in photovoltaic modules caused by bumps during transportation. The universal wheel supported by nylon material can move along the curved track, which is particularly suitable for walking on the color steel tile roof of large industrial plants. It will not cause concentrated loads and can also smoothly transport photovoltaic modules to the installation location.

[0080] refer to Figure 6 As shown, the anti-fall mechanism includes a safety anti-fall rope 202, which is made of steel wire rope. The safety anti-fall rope is set at a distance from the track, and the setting direction of the safety anti-fall rope is parallel to the direction of the track. The ends of the safety anti-fall rope are fixed to the two ends of the ridge line on the inner side of the roof through a fixing rod 201. Specifically, the two ends of the safety anti-fall rope pass through the fixing rod 201 and are fixed by an existing knotting method or a mechanical fixing method or a steel sleeve, and the bottom of the fixing rod can be fixed to the roof.

[0081] One end of the anti-tipping wire rope 203 is sleeved on the safety anti-falling rope, and the other end is connected to the carriage body. During the movement of the carriage body, when the carriage body 1 is moving, the anti-tipping wire rope 203 follows the carriage body along the horizontal safety anti-falling rope 202. When the carriage body 1 tends to tilt or flip, the anti-tipping wire rope 203 tightens the carriage body 1 to prevent it from sliding down and flipping, ensuring that the carriage body moves along the track. With the protection of the anti-falling mechanism 2, the carriage body 1 can move along the track on a roof with a set inclination angle;

[0082] It is easy to understand that at least one anti-tipping wire rope is provided, and in the present embodiment, two are specifically provided, to ensure the stability of the anti-falling vehicle body during movement; a first ring is provided at one end of the anti-tipping wire rope away from the bracket body, and the first ring is sleeved on the safety anti-falling rope, so that the first ring can be conveniently moved along the safety anti-falling rope during the movement of the bracket body along the track.

[0083] refer to Figure 7 As shown, the first guide mechanism and the third guide mechanism are set at a distance from one end of the track, and the second guide mechanism is set at a distance from the other end of the track;

[0084] The first guide mechanism is a first guide wheel 31, the second guide mechanism is a second guide wheel 32, and the third guide mechanism is a third guide wheel 33. The first guide wheel 31 and the third guide wheel 33 are arranged at a distance from each other or supported by the same fixed seat (each guide wheel is rotatable relative to the corresponding fixed seat). The bottom side of each guide wheel is higher than the tread of the track, ensuring that the first steel wire rope and the second steel wire rope are suspended above the tread of the track, so that the first steel wire rope bypassing the first guide mechanism and the second guide mechanism is higher than the photovoltaic component setting at the bracket body;

[0085] It is easy to understand that by changing the number and position of the traction mechanism, the first guide mechanism, the second guide mechanism and the third guide mechanism, traction of different bracket bodies can be achieved.

[0086] In addition, it needs to be explained that if the track exceeds 50 meters, additional guide wheels are set in sections between the first guide wheel and the second guide wheel to prevent the traction wire rope from bending downward and wearing the photovoltaic bracket; when the height of the photovoltaic components supported by the bracket body is relatively high, another guide wheel can be added to the bracket body to raise the first traction rope.

[0087] Regarding the traction mechanism, the traction mechanism 4 is an existing winch, and the traction mechanism 4 includes a drum, and the drum is wound with a first steel wire rope 43 and a second steel wire rope 45, and the first steel wire rope and the second steel wire rope have opposite directions of coming out.

[0088] refer to Figure 8As shown, a first limit end 42 and a third limit end 46 are respectively provided at both ends of the drum 41, a second limit end 44 is provided in the middle section of the drum, a first steel wire rope 43 is provided between the first limit end and the second limit end, a second steel wire rope 45 is provided between the second limit end and the third limit end, one end of the first steel wire rope is fixed at the first limit end, one end of the second steel wire rope is fixed at the third limit end, the way the drum is fixed to the ground is the same as the prior art, one end of the drum at the first limit end is connected to the motor to realize the rotation of the drum, the first steel wire rope extends upward from the rear side of the drum, and the second steel wire rope extends upward from the front side of the drum.

[0089] It needs to be explained that Figure 7 and Figure 8 The outgoing direction of the first steel rope in the drum is opposite, and the outgoing direction of the second steel rope is opposite, which is all possible, as long as the outgoing directions of the first steel rope and the second steel rope in the drum are opposite.

[0090] The transportation device provided in this embodiment uses the photovoltaic bracket 6 as a track after it is installed on the roof, on which a photovoltaic component bracket body 1 is arranged, and an anti-fall mechanism 2 is installed at the ridge, and the bracket body is connected by an anti-tipping wire rope. The bracket body uses a traction mechanism 4 as power, and the traction wire rope is passed through the guide mechanism to drag the bracket body to move on the photovoltaic bracket to complete the horizontal transportation of the photovoltaic components. Even if the roof is inclined, the bracket body can be guaranteed to move forward stably on the roof, thereby realizing the transportation of photovoltaic components on the roof. After the photovoltaic components are transported to the roof by the lifting equipment, they can be quickly dispersed to avoid the concentrated stacking of photovoltaic components on the roof for a long time without manual handling.

[0091] Embodiment 2

[0092] The difference between this embodiment and the first embodiment is that:

[0093] When the roof structure is relatively large, the anti-fall mechanism of the first embodiment may be provided on both opposite sides of the bracket body to further improve the stability of the bracket body during operation.

[0094] Embodiment 3

[0095] The difference between this embodiment and the first embodiment is that:
