Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic bracket installation, and in particular to a pushing mechanism and a flatbed trailer. Background Art

[0002] At present, photovoltaic arrays are generally built in the following order: first install the columns, then install the diagonal beams on the columns, then install the purlins on the diagonal beams, and then install the photovoltaic panels. In the above process, the diagonal beams and purlins are generally installed one by one, which has low installation efficiency, high labor intensity of manual installation, and requires a lot of manpower and high labor costs. In addition, the installation personnel need to work at high altitude for a long time, which increases the danger and is not conducive to the construction period and cost control of photovoltaic power station construction projects. Summary of the invention

[0003] In order to solve the above problems, the present application provides a pushing mechanism and a flatbed trailer, which are cleverly designed and simple in structure, can adjust the posture of the support frame relative to the column, and transport the support frame to the designated installation position, saving the cumbersome lifting process caused by lifting components one by one, reducing the labor intensity of workers, shortening the time for workers to work at high altitudes, reducing the danger of installation work, and improving the installation efficiency of the support frame. In addition, the present application does not require expensive mechanical components and devices, and the overall cost is low. The technical solutions adopted by the present application are as follows:

[0004] A pushing mechanism, used to assist the support frame to be installed on the top of the column, comprising:

[0005] A first platform, the first platform is used to place the support frame; a first translation module, the first translation module is installed at one side of the first platform, and is used to drive the support frame to translate on the first platform; an adjustment module, the adjustment module is arranged below the first platform, and is used to adjust the height and tilt angle of the first platform; a second translation module, the second translation module is arranged below the first platform, and is used to adjust the distance between the first platform and the column.

[0006] After the support frame is placed on the first platform, the push mechanism can adjust the posture of the support frame relative to the column, and can transport the support frame to the designated installation position, saving the cumbersome hoisting process caused by hoisting components one by one, reducing the labor intensity of workers, shortening the time of workers' high-altitude operations, reducing the danger of installation operations, and improving the installation efficiency of the support frame. In addition, the push mechanism does not require expensive mechanical components and devices, and the overall cost is low.

[0007] In some embodiments, the first stage includes a stage frame and a roller, the roller is mounted on the stage frame, and the support frame contacts the roller and translates on the plane of the roller.

[0008] By arranging rollers and placing the support frame on the rollers, the friction force of the support frame when moving on the first carrier can be reduced, the smoothness of the movement of the support frame can be improved, and the power requirement for the first translation module can be reduced.

[0009] In some embodiments, the first translation module includes a first push rod, which is installed at the other end of the first platform opposite to the column, and the telescopic end of the first push rod is suitable for pushing the support frame.

[0010] By providing the first push rod, the support frame can be pushed to a specified position by using the first push rod. Compared with using a slide rail or a conveyor belt, this has a simple structure and low manufacturing cost.

[0011] In some embodiments, the adjustment module includes a height adjustment module and a tilt adjustment module, the height adjustment module is used to adjust the height of the first carrier, and the tilt adjustment module is used to adjust the tilt angle of the first carrier.

[0012] In some embodiments, a support rod is provided on the upper portion of the height adjustment module, one end of the support rod is connected to the height adjustment module, and the other end is hinged to the first carrier; the inclination angle adjustment module includes a second push rod, one end of the second push rod is connected to the upper portion of the height adjustment module, and the other end is hinged to the first carrier, and the inclination angle of the first carrier can be adjusted by adjusting the telescopic length of the second push rod.

[0013] By providing a second push rod and combining the support rod with the hinged connection of the first platform, the inclination angle of the first platform can be adjusted. The mechanism for adjusting the inclination angle of the first platform is simple in composition and does not require complex mechanism design.

[0014] In some embodiments, the height adjustment module includes a scissor lift platform.

[0015] The overall height of the scissor lift platform is relatively low when it is in the retracted state, which can reduce the height space occupied by the push mechanism when it is not raised. At the same time, after the support frame is placed on the first platform, the center of gravity of the support frame can be lowered, reducing the amplitude or risk of shaking of the support frame during transportation with the push mechanism.

[0016] In some embodiments, the inclination adjustment module is disposed between the scissor-type lifting platform and the first carrier, and the scissor-type lifting platform is disposed on the second translation module.

[0017] By arranging the scissors-type lifting platform on the second translation module, compared to arranging the second translation module on the scissors-type lifting platform, it can avoid the relative change of the positions of the support frame and the scissors-type lifting platform when the support frame moves under the action of the second translation module, thereby improving the force eccentricity of the scissors-type lifting platform and allowing the scissors-type lifting platform to work stably.

[0018] In some embodiments, the second translation module includes a linear slide rail, and the adjustment module is installed on a slider of the linear slide rail.

[0019] In some embodiments, the first push rod is an electric push rod.

[0020] In some embodiments, along the arrangement direction of the columns, a plurality of the first translation modules, the adjustment modules, and the second translation modules are provided.

[0021] On the other hand, the present application provides a flatbed trailer, including a trailer body and the aforementioned pushing mechanism, wherein the pushing mechanism is installed on the trailer body.

[0022] By installing the pushing mechanism on the trailer body, after the support frame is placed on the pushing mechanism, the trailer body can be used to directly transport the support frame and the pushing mechanism as a whole to the installation site. Compared with transporting the pushing mechanism and the support frame to the installation site separately and then placing the support frame on the pushing mechanism, the time before installing the support frame can be reduced.

[0023] The push mechanism and flatbed trailer provided in the present application have at least one of the following beneficial effects:

[0024] 1. The application provides a push mechanism. After the support frame is placed on the first platform, the push mechanism can adjust the posture of the support frame relative to the column and transport the support frame to the designated installation position, saving the cumbersome hoisting process caused by hoisting components one by one, reducing the labor intensity of workers, shortening the time of workers' high-altitude operations, reducing the danger of installation operations, and improving the installation efficiency of the support frame. In addition, the push mechanism does not require expensive mechanical components and devices, and the overall cost is low.

[0025] 2. The present application provides a pushing mechanism, which, by setting rollers and placing a support frame on the rollers, can reduce the friction force of the support frame when it moves on the first carrier, improve the smoothness of the movement of the support frame, and at the same time reduce the power requirement for the first translation module.

[0026] 3. The present application provides a pushing mechanism, which can push the support frame to a specified position by setting a first pushing rod. Compared with the use of a slide rail or a conveyor belt, this has a simple structure and low manufacturing cost.

[0027] 4. The present application provides a pushing mechanism, which can adjust the inclination angle of the first carrier by setting a second push rod and combining the support rod with the hinge of the first carrier. The mechanism for adjusting the inclination angle of the first carrier is simple in composition and does not require complex mechanism design.

[0028] 5. The push mechanism provided in the present application has a relatively low overall height when the scissor-type lifting platform is in the retracted state, which can reduce the height space occupied by the push mechanism when it is not raised. At the same time, after the support frame is placed on the first platform, the center of gravity of the support frame can be lowered, reducing the amplitude or risk of shaking of the support frame during transportation with the push mechanism.

[0029] 6. The present application provides a pushing mechanism, which, compared with placing the second translation module on the scissors-type lifting platform, can avoid relative changes in the positions of the support frame and the scissors-type lifting platform when the support frame moves under the action of the second translation module, thereby improving the eccentricity of the force of the scissors-type lifting platform and enabling the scissors-type lifting platform to work stably.

[0030] 7. The present application provides a flatbed trailer, which installs a pushing mechanism on the trailer body. After the support frame is placed on the pushing mechanism, the trailer body can be used to directly transport the support frame and the pushing mechanism as a whole to the installation site. Compared with transporting the pushing mechanism and the support frame to the installation site separately and then placing the support frame on the pushing mechanism, the time spent before installing the support frame can be reduced.

DETAILED DESCRIPTION

[0039] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0040] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0041] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0042] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] refer to Figure 4 , Figure 5The present application provides a pushing mechanism, including: a first platform 1, a first translation module, a second translation module and an adjustment module; the first translation module includes a first push rod 4, which is installed at the other end of the first platform 1 opposite to the column 12, and the telescopic end of the first push rod 4 can push the bracket frame 8; the adjustment module includes a height adjustment module and an inclination adjustment module, the height adjustment module includes a scissors-type lifting platform 6, and a support rod 14 is provided on the upper part of the scissors-type lifting platform 6, one end of the support rod 14 is connected to the scissors-type lifting platform 6, and the other end is hinged to the first platform 1; the inclination adjustment module includes a second push rod 5, one end of the second push rod 5 is connected to the upper part of the scissors-type lifting platform 6, and the other end is hinged to the first platform 1, by adjusting the telescopic length of the second push rod 5, the first platform 1 is driven to rotate around the hinge point between the first platform 1 and the support rod 14, thereby realizing the adjustment of the inclination angle of the first platform 1. The second translation module includes a linear slide rail 7, and a scissor-type lifting platform 6 is installed on a slider of the linear slide rail 7. As the slider moves, the scissor-type lifting platform 6 can be driven to move, ultimately achieving the purpose of adjusting the distance between the first carrier 1 and the column 12.

[0045] Specifically, combined Figure 1-Figure 3 , the installation process of the auxiliary support frame 8 of the present application is introduced as an example. At present, when installing a single-column photovoltaic support, it is necessary to first lift the inclined beam 9 and the diagonal brace 10 with the help of a lifting device, and manually install the inclined beam 9 and the diagonal brace 10 on the column 12, and then use the lifting equipment to install the purlin 11 on the inclined beam 9, and finally form the following Figure 3 The single-column photovoltaic bracket shown. The above installation process requires the use of lifting equipment to lift the components one by one, which is time-consuming and labor-intensive. In addition, workers are required to work at high altitudes for a long time, which is very dangerous. The present application is designed for a bracket frame 8 pre-assembled from components such as purlins 11, diagonal beams 9, and diagonal braces 10. The bracket frame 8 can be pre-assembled at low altitudes. The diagonal braces 10 are hingedly connected to the diagonal beams 9 through connectors. The purlins 11 are installed on the diagonal beams 9 through connectors. When the bracket frame 8 is placed on the first carrier 1, the diagonal braces 10 and the diagonal beams 9 are in a position as shown in the figure. Figure 1The folded state shown, that is, the diagonal beam 9 and the diagonal brace 10 are not unfolded, and the two are basically parallel. When the pushing mechanism carries the support frame 8 to the vicinity of the column 12, by adjusting the pushing distance of the support frame 8 by the first push rod 4, the adjustment of the height and inclination angle of the support frame 8 by other modules, and the adjustment of the distance between the support frame 8 and the column 12 by the linear slide rail 7, the mounting hole of the diagonal beam 9 and the mounting hole of the column 12 are aligned, and then the diagonal beam 9 in the support frame 8 is connected to the column 12. It can be understood that when the diagonal beam 9 is connected to the column 12, a part of the diagonal beam 9 is cantilevered out of the first platform 1. After the diagonal beam 9 is connected to the column 12, by lowering the height of the first platform 1 and at the same time moving the first platform 1 away from the column 12, the length of the support frame 8 cantilevered out of the first platform 1 can be gradually lengthened while the inclination angle of the support frame 8 remains unchanged, that is, more part of the support frame 8 is exposed from the first platform 1, thereby providing space for the unfolding of the diagonal brace 10. Figure 2 The state of the diagonal brace 10 after being unfolded is shown, after which the diagonal brace 10 can be connected to the column 12, and the installation of the support frame 8 and the column 12 is completed.

[0046] It can be understood that the present application can adjust the posture of the support frame 8 relative to the column 12, and can transport the support frame 8 to the designated installation position, saving the cumbersome lifting process brought about by lifting components one by one, reducing the labor intensity of workers, shortening the time of workers' high-altitude operations, reducing the danger of installation operations, and improving the installation efficiency of the support frame 8.

[0047] It is easy to understand that the first carrier 1 can be a plate or a Figure 4 The combination of the platform frame 2 and the roller 3 is shown, the roller 3 is installed on the platform frame 2, and the support frame 8 can be placed on the roller 3. When the support frame 8 moves with the rotation of the roller 3, the resistance is small and the movement is smooth.

[0048] In this embodiment, the first push rod 4 and the second push rod 5 can be electric push rods, hydraulic push rods, or pneumatic push rods, preferably electric push rods. In other embodiments, the first translation module can be a slide rail or a conveyor belt instead of a push rod. For example, the slide rail or the conveyor belt can be installed on both sides or in the middle of the first platform 1, and the length direction of the slide rail or the conveyor belt is the same as the length direction of the inclined beam 9 when the support frame 8 is placed on the first platform 1.

[0049] It can be understood that the second translation module needs to be fixed on a planar structure. In the present embodiment, the second translation module is a linear slide rail 7, while in other embodiments, the second translation module can be a push rod, which pushes the scissors-type lifting platform 6 to move on the planar structure. It is worth noting that rollers can be provided at the bottom of the scissors-type lifting platform 6 to reduce the resistance when the push rod pushes the scissors-type lifting platform 6 to move.

[0050] It is worth noting that in other embodiments, the adjustment module is composed of at least three push rods, which are distributed at the three vertices of the triangle and are arranged vertically. The top ends of the three push rods are respectively connected to the first platform 1, and the bottom ends of the three push rods are respectively installed on the second translation module, which can drive the three push rods away from or close to the column 12 when the second translation module is working. It can be understood that by adjusting the telescopic length of the three push rods, not only the height of the first platform 1 can be adjusted, but also the inclination angle of the first platform 1 can be adjusted. Obviously, the number of push rods can also be four or five, or other numbers.

[0051] Another point that needs to be explained is that, in other embodiments, the height adjustment module may not be a scissor-type lifting platform 6, but other lifting devices, such as a lifting device composed of a push rod, a retractable sleeve and an upper and lower flat plate. The upper and lower ends of the push rod are respectively connected to the upper and lower flat plates, and the upper and lower ends of the sleeve are also respectively connected to the upper and lower flat plates. The sleeve plays a guiding role to prevent the push rod from being eccentrically stressed, and at the same time, it also keeps the upper and lower flat plates parallel. The lower plate is connected to the second translation module, and the upper plate is connected to the first carrier 1 through the second push rod 5 and the support rod 14.

[0052] It is worth noting that in the present embodiment, the inclination adjustment module is arranged between the scissor-type lifting platform 6 and the first carrier 1, and the scissor-type lifting platform 6 is arranged on the second translation module. In other embodiments, the second translation module can be arranged on the top of the height adjustment module, and the inclination adjustment module can be arranged on the upper part of the second translation module, or the second translation module can be arranged on the upper part of the adjustment module, or the inclination adjustment module can be arranged at the bottom of each module. It can be understood that, except for the first translation module, no matter how the other modules are arranged vertically, as long as the first carrier 1 is ensured to be at the top, the height of the first carrier 1, the inclination angle of the first carrier 1, and the distance between the first carrier 1 and the column 12 can be adjusted through reasonable settings.

[0053] In one embodiment, a plurality of first translation modules, adjustment modules, and second translation modules are provided along the arrangement direction of the columns 12. It is understandable that a plurality of first translation modules, adjustment modules, and second translation modules are provided, which can provide uniform support and push for the support frame 8, improve the stability of the support frame 8 during installation, and improve installation accuracy and efficiency.

[0054] refer to Figure 4 , Figure 5 The present application also provides a flatbed trailer, including: a trailer body 13 and the aforementioned pushing mechanism, the pushing mechanism is installed on the trailer body 13, that is, the trailer body 13 provides a mounting platform for the pushing mechanism, and the trailer body 13 functions relative to the planar structure mentioned above.

[0055] The specific structure of the pushing mechanism refers to the aforementioned embodiment. Since the flatbed trailer adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.

[0056] It can be understood that by installing the pushing mechanism on the trailer body 13, after the support frame 8 is placed on the pushing mechanism, the trailer body 13 can be used to directly transport the support frame 8 and the pushing mechanism as a whole to the installation site. Compared with transporting the pushing mechanism and the support frame 8 to the installation site separately and then placing the support frame 8 on the pushing mechanism, the time spent before installing the support frame 8 can be reduced.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
