Description

[0002] This utility model relates to the field of trailer equipment technology, and in particular to a connecting bracket, trailer and installation system. Background Technology

[0003] A trailer is a structure that connects to a power unit via a connecting bracket, allowing it to move alongside the power unit. It possesses excellent load-bearing capacity, capable of carrying the power required for the power unit's operation, as well as a large amount of materials needed for the power unit's work. Currently, commonly used connecting brackets for trailers and power units often feature a pointed triangular structure to ensure stable transmission and flexible turning during the power unit's operation. However, during the installation of photovoltaic modules, which are often assembled in a regular array structure, the power unit needs to drive the trailer in a straight line as much as possible to avoid collisions with the photovoltaic modules. Current connecting brackets, due to their pointed design, can cause significant risk of skewing when the weight is asymmetrical at the dragging point, affecting the accuracy and safety of the assembly process.

[0004] Therefore, improving the safety and accuracy of photovoltaic module installation is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0034] The core of this utility model is to disclose a connecting bracket, trailer and installation system to realize the relative rotation and linear operation requirements of the equipment at both ends of the connecting bracket. When used in the photovoltaic module installation process, it can improve the safety of the photovoltaic module installation process and improve the accuracy of the installation position.

[0035] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0036] like Figure 1As shown, the connecting bracket provided in this disclosure is used to connect a first device and a second device to achieve power transmission between the two devices. Specifically, the connecting bracket mainly includes a first connecting part 10, a second connecting part 20, a first limiting component 30, and a second limiting component 40. The first connecting part 10 and the second connecting part 20 are hinged together to enable force transmission, allowing the connecting bracket to have sufficient extension distance to connect with the devices on both sides. At the same time, the hinged cooperation of the first connecting part 10 and the second connecting part 20 is used to adjust the relative height of the first connecting part 10 and the second connecting part 20 in the vertical direction, so that the first connecting part 10 and the second connecting part 20 are coplanar or have a certain included angle, and can also be used for first devices and second devices with different connection heights.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the first connecting part 10 is provided with a connecting end 110 for hinged connection with the first device. It should be noted that the connecting end 110 can be a shaft or a connecting ring structure, depending on the connection requirements with the first device, to achieve a hinged fit. The second connecting part 20 is provided with a rotary table 210, and the second device is provided with a rotary table fitting sleeve to achieve a rotatable connection with the second connecting part 20. In the above structure, at least one of the first and second devices is a power-driven device. If the first device is a power-driven device, then the first device can drive the second device to perform linear and turning movements through the connecting bracket.

[0038] Based on this, a first limiting component 30 is also provided on the first connecting part 10, such as Figure 1 and Figure 3 As shown, the first limiting component 30 specifically includes at least two limiting legs 310, and the two limiting legs 310 have the same extension length on the side facing the first device. The first limiting component 30 is rotatably mounted on the first connecting portion 10, and the first limiting component 30 passes through at least a first position and a second position during its rotation relative to the first connecting portion 10. Specifically, as shown... Figure 1 and Figure 7As shown, when the first limiting component 30 rotates to the first position, one end of each limiting leg 310 abuts against the same wall surface of the first device to limit the first connecting part 10 and the first device. It should be noted that when the first connecting part 10 and the first device are about to rotate relative to each other, the abutting action of the limiting leg 310 will generate rotational resistance and prevent the relative rotation of the first connecting part 10 and the first device. The abutting action of the limiting leg 310 exists until its structure is damaged, thus achieving its limiting effect. It should also be noted that, preferably, when the first limiting component 30 is in the first position, there is at least one limiting leg 310 on each side of the connecting end 110, so as to effectively limit the turning of the first connecting part 10 and the first device in two directions.

[0039] Furthermore, such as Figure 1 , Figure 8 and Figure 9 As shown, when the first limiting component 30 rotates to the second position, it separates from the first device. At this time, the connecting bracket is hinged to the first device only through the connecting end 110 on the first connecting part 10, and can rotate relative to the first device. By adjusting the relative position of the first limiting component 30 and the first connecting part 10, the limiting state of the first connecting part 10 and the first device can be adjusted. That is, when the two need to rotate relative to each other to achieve a turn, the first limiting component 30 is rotated to the second position, and when the two need to achieve linear drive, the first limiting component 30 is rotated to the first position to meet different operating conditions.

[0040] And such Figure 1 , Figure 5 and Figure 9 As shown, the second limiting component 40 provided in this disclosure specifically includes a limiting sleeve 410 and a limiting pin 420. The limiting sleeve 410 is fixedly disposed on the second connecting part 20. It is a rigid structure with an opening so that the limiting pin 420 can pass through. It should be noted that the second limiting component 40 is used to limit the second connecting part 20 and the second device. With the limiting sleeve 410 fixedly disposed on the second connecting part 20, the second device only needs to have a corresponding opening or a collar structure for the limiting pin 420 to pass through, and rotational locking can be achieved by the limiting pin 420. When the limiting pin 420 is inserted into the corresponding hole on the limiting sleeve 410 and the second device, the second connecting part 20 and the second device have no other connection points except for the rotary table 210, and can no longer rotate around the rotary table 210 as the rotation center, thus meeting the requirements of linear transmission.

[0041] It should be noted that the structure of the limiting sleeve 410 and the limiting pin 420 allows for convenient assembly and disassembly. When rotational limiting of the second connecting part 20 and the second device is required, the limiting pin 420 is inserted to achieve rotational limiting; and when turning is required, the limiting pin 420 is removed to restore the rotational connection between the two. In this disclosure, the limiting pin 420 only needs to have a certain angle with the rotation plane where the rotary table 210 is located to achieve rotational limiting of the second connecting part 20 and the second device; in a specific embodiment, the limiting pin 420 is set perpendicular to the rotation plane where the rotary table 210 is located, that is, when the second device is driven in the horizontal plane, the limiting pin 420 can pass through the hole structure on the limiting sleeve 410 and the second device in the vertical direction to achieve the limiting effect.

[0042] The above embodiments, through the first limiting component 30 and the second limiting component 40, can respectively limit the first connecting part 10 and the second connecting part 20 on the connecting bracket, thereby satisfying various operating conditions. That is, since the first limiting component 30 and the second limiting component 40 can be set independently, when it is necessary to limit the relative rotation of the first connecting part 10 and the first device, the first limiting component 30 can be rotated to the first position independently; and when it is necessary to limit the relative rotation of the second connecting part 20 and the second device, the first limiting component 30 can be rotated to the second position, and the limiting sleeve 410 and the limiting pin 420 can be inserted to satisfy the limiting. At the same time, the two limiting components can also be used simultaneously. In this case, when the second device moves in a straight line, the first device can move synchronously along a straight line under the limiting action of the connecting bracket without the risk of deflection.

[0043] Furthermore, the limiting leg 310 only needs to abut against the same wall surface of the first device at its end to achieve rotational limiting of the first device and the first connecting part 10 by the first limiting component 30. Adjacent limiting legs 310 can be arranged in a contracting structure, an opening structure, or a parallel structure towards the first device. To improve the uniformity and stability of the limiting effect, in some embodiments of this disclosure, adjacent limiting legs 310 are arranged in parallel; simultaneously, to reduce the damage to the rigid contact surface of the limiting leg 310 to the first device when it abuts against the first device, such as... Figure 3As shown, each limiting leg 310 in this disclosure has a roller 320 rotatably mounted at one end. When the first limiting component 30 is in the first position, the roller 320's wheel surface area abuts against the same wall surface of the first device. It should be noted that the wheel surface area of ​​the roller 320 is the wall surface area of ​​the arc-shaped annular structure. The limiting leg 310 abutting against the first device via the roller 320 also achieves the effect of limiting and locking the rotation of the first connecting part 10 and the first device. Simultaneously, the rotation of the roller 320 maintains an arc-shaped contact structure of the same area when the first device tends to deviate, reducing the risk of stress concentration. Furthermore, the rotating roller 320 provides a certain offset range, allowing the first device to have an error adjustment range while maintaining safe operation, thus avoiding damage to the connecting structure under rigid limiting.

[0044] Furthermore, the first limiting component 30 needs to be rotatably mounted on the first connecting portion 10 to achieve position switching and maintain limiting stability in the first position. Therefore, in some embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, the first connecting part 10 extends outwards on both sides with mounting shafts 120. Specifically, during the use of the connecting bracket, the first connecting part 10 extends outwards on both sides along its direction of movement with mounting shafts 120. Correspondingly, the limiting leg 310 has a connecting hole 3110. The limiting leg 310 can be a structurally stable square tube, and the connecting hole 3110 penetrates the opposite side walls of the limiting leg 310 and is parallel to the axis of the mounting shaft 120. On this basis, the two limiting legs 310 are respectively sleeved on the two mounting shafts 120 from both sides of the first connecting part 10, and rotate relative to the first connecting part 10 with the axis of the mounting shaft 120 as the rotation center. The rotating structure sleeved on both sides can reduce the risk of skew during the overall rotation of the first limiting component 30, and the rotation process can be driven by a motor or manually driven by an operator.

[0045] Based on the above embodiments, when the first limiting component 30 rotates to the first position with the mounting shaft 120 as the rotation center, it abuts against the first device through the limiting leg 310. At this time, the first connecting part 10 needs to maintain rotational lock with the first limiting part on its setting plane in order to achieve rotational limiting between the first device and the first connecting part 10. Regarding the locking of the first connecting part 10 with the first limiting part on its setting plane, since the rotation plane of the first limiting component 30 is perpendicular to the setting plane of the first connecting part 10, the rotational locking of the two can be achieved by means of the support shaft 130. To avoid damage to the mounting shaft 120 when the limiting force is large, in some embodiments of this disclosure, the first connecting part 10 is also provided with a support shaft 130, which is arranged parallel to the mounting shaft 120; and as... Figure 3and Figure 4 As shown, a limiting groove 3120 is also provided on one side of the limiting leg 310. The limiting groove 3120 can be configured as a U-shaped structure to achieve quick engagement with the support shaft 130 through the opening area. The support shaft 130 is preferably configured in a one-to-one correspondence with the limiting leg 310. When the first limiting component 30 is in the first position, the support shaft 130 is engaged with the limiting groove 3120 to effectively support the limiting leg 310. It should also be noted that when the support shaft 130 and the limiting groove 3120 are engaged, the limiting leg 310 and the first connecting part 10 are coplanar. This ensures that when the limiting leg 310 rotates and limits the first connecting part 10 and the first device, the limiting force is located on the plane of the first connecting part 10. The stability of the force of the first limiting component 30 is improved by the coplanar action.

[0046] It should be noted that a reinforcing plate can also be welded and fixed at the location where the limiting groove 3120 is provided on the side wall of the limiting leg 310, so as to reduce the destructive effect of the setting of the limiting groove 3120 on the structure of the limiting leg 310 and improve the structural stability of the limiting leg 310 when performing the limiting function.

[0047] Furthermore, the limiting leg 310 in the first limiting component 30 only needs to be separated from the first device to achieve rotational limiting and unlocking of the first connecting part 10 and the first device. In order to avoid abnormal rotation of the limiting leg 310 and affect the working process, in some embodiments of this disclosure, the first connecting part 10 is also provided with a connecting hook 140, so as to lock the first limiting component 30 when it is in the second position by the hooking action of the connecting hook 140. Correspondingly, the first limiting component 30 includes a support beam 330 for connecting two adjacent limiting legs 310. The support beam 330 is arranged perpendicular to the limiting leg 310 to form an "I" structure with the two adjacent limiting legs 310. The support beam 330 can be a pipe beam or a U-shaped beam, and the support beam 330 has a locking hole 3310 at the midpoint of its length direction, that is, the locking hole 3310 is located at the symmetrical line position of the two adjacent limiting legs 310. Based on this, when the first limiting component 30 is in the second position, the connecting hook 140 locks into the locking hole 3310 to achieve a stable setting of the first limiting component 30. The setting of the support beam 330 not only maintains the integrity of the structure of the first limiting component 30, but also avoids further damage to the limiting leg 310 caused by opening the locking hole 3310 on the limiting leg 310.

[0048] It should be noted that in some embodiments, the support beam 330 can be raised in the middle region along its length, and the locking hole 3310 is located in the raised region so that when the first limiting component 30 is in the second position, the locking hole 3310 can be located closer to the connecting hook 140, thereby improving the convenience of locking the connecting hook 140 to the limiting leg 310.

[0049] Furthermore, to improve the versatility of the connecting bracket, in some embodiments of this disclosure, at least two connecting holes 3110 are provided at intervals along the length direction of the limiting leg 310, so that for a single mounting shaft 120, the limiting leg 310 has at least two different mounting positions. Different mounting positions allow the limiting leg 310 to correspond to different extension lengths. That is, when the connecting end 110 on the first connecting part 10 is connected to the first device, the limiting leg 310 can contact and abut against the wall surface of different first devices by changing the mounting position of different connecting holes 3110. By setting multiple sets of connecting holes 3110 according to the commonly used first devices and the structural length of the limiting leg 310, the connection of different first devices can be realized through a single set of connecting brackets, and all of them can meet their rotation limiting effect, thereby improving the versatility of the connecting bracket and reducing production costs.

[0050] Based on currently used connection structures, in connection brackets, such as Figure 2 As shown, the first connecting part 10 is an isosceles triangle structure, and the connecting end 110 is located at the vertex of the triangle. The second connecting part 20 is hinged to the base of the triangle. In order to maintain the stability of the connection, the connecting end 110 is located on the perpendicular bisector of the base of the triangle structure, so that the first connecting part 10 is evenly subjected to tension from both sides of the connecting end 110.

[0051] In addition, it should be noted that, as Figure 1 , Figure 5 and Figure 6As shown, the second connecting part 20 needs to achieve linear force transmission with the first connecting part 10. Therefore, it is hinged to the first connecting part 10 through at least two spaced hinge points to improve connection stability and reduce the risk of skewing. It should be noted that the rotation direction of the first connecting part 10 relative to the second connecting part 20 is vertical, causing the connecting end 110 to rotate towards and away from the second device. This is to change the relative height of the first connecting part 10 and the second connecting part 20, thus adapting to devices with different connection heights. Furthermore, the bottom of the second connecting part 20 is also equipped with a pair of wheels 220. When the second device is an independent vehicle structure, these wheels can engage with the rear wheels of the second device to contact the working surface for smooth towing. When the second device is a combination structure such as a motor, it can also be equipped with only a single wheel system to combine with the wheels 220 on the second connecting part 20 for driving motion, thus improving the versatility of the connecting bracket.

[0052] Furthermore, such as Figure 7 , Figure 8 and Figure 9 As shown, this disclosure also provides a trailer 50, which has a connecting bracket 60 provided in any of the above embodiments installed at its head in the direction of travel. Specifically, the trailer 50 includes a chassis bracket 510 that supports other assemblies. The chassis bracket 510 is connected to a turntable 210 to achieve a rotatable connection with the second connecting portion 20 on the connecting bracket 60. Meanwhile, the chassis bracket 510 overlaps with the second connecting portion 20 in the vertical direction. Based on this, a locking sleeve 520 is provided on the chassis bracket 510. The locking sleeve 520 also has a through hole and is coaxially arranged with the limiting sleeve 410 in the vertical direction. The L-shaped limiting pin 420 can pass through both the locking sleeve 520 and the limiting sleeve 410 simultaneously to achieve rotational limitation between the second connecting portion 20 and the chassis bracket 510. When linear drive is required, inserting the limiting pin 420 into the locking sleeve 520 and the limiting sleeve 410 achieves rotational locking between the connecting bracket 60 and the trailer 50. When rotation is required, the limiting pin 420 can be removed to meet the relative rotation requirements between the connecting bracket 60 and the trailer 50. It should also be noted that since the connecting bracket 60 has the technical effects provided by any of the above embodiments, the trailer 50 also has the above technical effects, which will not be repeated here.

[0053] In addition, such as Figure 10 and Figure 11As shown, this disclosure also provides an installation system for installing photovoltaic modules. Specifically, the installation system includes an installation robot 70 and a trailer 50 as described in the above embodiments. The installation robot 70 performs the installation action of the photovoltaic modules and provides driving force to drive the trailer 50 to move through the connecting bracket 60 and perform the operation at the target position. A hook is provided on one side of the installation robot 70 to engage with the connecting end 110, which is a connecting ring structure on the connecting bracket 60. Due to the first limiting component 30 and the second limiting component 40 on the connecting bracket 60, the installation robot 70 can achieve stable linear drive of the trailer 50, thereby reducing the risk of the trailer 50 deviating and damaging the photovoltaic modules during operation. At the same time, for photovoltaic modules arranged in an array, it can also improve the accuracy of the operation and installation position of the installation robot 70 and the trailer 50.
