Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket correction, in particular to a photovoltaic bracket correction device. Background Art

[0002] The purlin is a component of the photovoltaic support system and is used to directly support photovoltaic panels. During the production of purlins, due to factors such as the temperature difference of the heated raw materials during the hot rolling process of steel and the uneven cooling during the rolling process, the rolled pieces will extend unevenly, resulting in the bending of the purlin shape after hot rolling. Therefore, a correction device is needed to straighten and shape it to ensure its accuracy and stability during the installation process.

[0003] After searching, the Chinese patent publication number CN205945602U discloses a photovoltaic bracket purlin correction frame, including a plurality of pillars, the pillars are fixedly connected to the bottom bracket, the middle bracket and the top bracket arranged from bottom to top, the bottom bracket is fixedly provided with a base plate, the base plate is fixedly installed with a jack, and the top supporting part of the jack is fixedly connected with a correction cross bar; the middle bracket is a square frame bracket formed by four square steels, and two spaced supporting cross bars are arranged in the middle of the square frame bracket; the top bracket is a square frame bracket formed by four square steels; the distance between the top bracket and the middle bracket is 1.5-2 times the width of the purlin.

[0004] The above patent has the following shortcomings: it uses a jack to drive the correction cross bar upward, thereby pressing the purlin to achieve a straightening effect, but the purlin is blocked by the bracket above, so that the degree of bending during correction is limited. Since the purlin has toughness and elasticity, when it bends within the elastic deformation range, it will bend and rebound due to the elastic action when the external force is removed, resulting in poor straightening effect on the purlin.

[0005] To this end, a photovoltaic support correction device is proposed. Utility Model Content

[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] like Figure 1-3 As shown, a photovoltaic support correction device includes a body 1 and a material receiving mechanism 2 arranged on one side of the body 1.

[0035] A correction component 3 for correcting purlins and a defect detection component 4 for detecting defects in purlins are arranged inside the machine body 1. The correction component 3 includes two mounting frames 7 and two correction rollers 11 rotatably connected to the inner wall of the machine body 1 through a rotating shaft 10. The inner wall of the mounting frame 7 is rotatably connected to a correction roller 9 through a rotating shaft 6. The two correction rollers 9 and the correction rollers 11 are staggered. The outer wall of the mounting frame 7 is fixedly connected to a hydraulic rod 8. The fixed ends of the two hydraulic rods 8 are respectively fixed to the top lower surface and the bottom upper surface of the machine body 1.

[0036] Insert the purlin from the end of the machine body 1 away from the material receiving mechanism 2. After the purlin enters the machine body 1, it first passes through the defect detection component 4. During this period, the defect detection component 4 performs defect detection on the purlin. Then, after the purlin passes between one set of correction rollers 1 9 and 11, the motor 5 is started to drive the rotating shaft 1 6 to drive the correction roller 1 9 to rotate, and the purlin is driven to move to the other end of the machine body 1 with the cooperation of the correction roller 1 9 and the correction roller 2 11. When the defect detection component 4 detects that the purlin has a bend, the corresponding hydraulic rod 8 is started to drive the correction roller 1 9 to descend or rise, and the purlin is over-bent, and the desired bending angle is achieved by the elastic rebound of the purlin itself.

[0037] The device is provided with two offset correction rollers 9, which can perform correction according to the different bending directions of the purlins, and the cooperation of the hydraulic rod 8 and the correction roller 9 can be used to over-bend the purlins, and the elastic rebound of the purlins themselves can be used to achieve the required bending angle, thereby avoiding the rebound of the purlins after correction, resulting in poor correction effect.

[0038] like Figure 3 As shown, one of the rotating shafts 6 is fixedly connected to a motor 5 via a coupling, and the motor 5 is fixed to the outer wall of the mounting frame 7 via bolts.

[0039] The starting motor 5 drives one of the rotating shafts 1 6 to drive the correction roller 1 9 to rotate, and the correction roller 1 9 and the correction roller 2 11 cooperate to drive the purlin to move to the other end of the machine body 1, thereby realizing the transmission of the purlin.

[0040] like Figure 2 , 4 As shown in , 5, the defect detection component 4 includes a plurality of staggered auxiliary rollers 13, and the inner wall keys of the auxiliary rollers 13 are connected to the rotating shaft 3 12.

[0041] The inner wall of the body 1 is symmetrically provided with slide grooves 16, and the inner wall of the slide groove 16 is slidably matched with a slider 14, and the rotating shaft 12 is rotatably connected to the opposite side of the two sliders 14, and the opposite side of the slider 14 and the slide groove 16 is buckled with a spring 15, and the opposite side of the slider 14 and the slide groove 16 is installed with an infrared rangefinder 17.

[0042] A circuit board is installed in the machine body 1, and the motor 5, the hydraulic rod 8 and the infrared rangefinder 17 are all connected to the circuit board through an integrated wiring harness.

[0043] The auxiliary rollers 13 are staggered, and the purlin is passed horizontally between all the auxiliary rollers 13 and continues to be pushed for a distance until the purlin crosses between one set of correction rollers 19 and correction roller 2 11 and stops. When the purlin crosses between the auxiliary rollers 13, its bending part will push up or down the auxiliary roller 13. The infrared rangefinder 17 detects the change in the distance between the slider 14 and transmits the signal to the circuit board. After receiving and analyzing the signal, the circuit board starts the corresponding hydraulic rod 8 to drive the mounting frame 7 and the correction roller 19 to rise or fall according to the degree of bending of the purlin, thereby correcting the purlin.

[0044] By providing a plurality of staggered auxiliary rollers 13, the device can detect the bending position and bending degree of the purlin in real time with the cooperation of the infrared rangefinder 17, thereby achieving real-time targeted correction and improving the accuracy of correction.

[0045] In this embodiment: when in use, the purlin is first inserted from the end of the machine body 1 away from the material receiving mechanism 2, and passed horizontally between all the auxiliary rollers 13, and then the purlin is pushed until it crosses between one group of correction rollers 19 and correction rollers 2 11 and then stops. When the purlin crosses between the auxiliary rollers 13, its bending part will push up or down the auxiliary rollers 13, and the infrared rangefinder 17 detects that the distance between it and the slider 14 changes, and transmits the signal to the circuit board. After receiving and analyzing the signal, the circuit board starts the corresponding hydraulic rod 8 to drive the mounting frame 7 and the correction roller 19 to rise or fall according to the degree of bending of the purlin, and then starts the motor 5 to drive the rotating shaft 6 to drive the correction roller 19 to rotate, and uses the cooperation of the correction roller 19 and the correction roller 2 11 to transport the purlin until the purlin is corrected and reaches the material receiving mechanism 2 for unified collection.

[0046] Embodiment 2:

[0047] A photovoltaic support correction device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1 , 6 、7 as shown:

[0049] A limit block 20 is fixed to the outer wall of the material receiving box 18, and two guide blocks 24 are fixed to the outer wall of the door panel 19. The same locking pin 23 is movably fitted inside the two guide blocks 24. The locking pin 23 is limitedly fitted with the limit block 20, and a handle 21 is fixed to the outer wall between the two guide blocks 24. A locking plate 22 that is limitedly fitted with the handle 21 is fixed to the outer wall of the door panel 19 by bolts.

[0050] In this embodiment: the corrected purlins are uniformly transported to the receiving box 18. When the purlins need to be taken out, the handle 21 is held and rotated along the axis of the locking pin 23, so that the handle 21 is disengaged from the locking plate 22. At this time, the handle 21 is used to drive the locking pin 23 to move to the side away from the limit block 20, so that the locking pin 23 is disengaged from the limit block 20. At this time, the door panel 19 can be rotated open without restriction. Conversely, the locking pin 23 can be inserted into the limit block 20 to achieve the locking of the door panel 19.

[0051] The device is provided with a material collecting box 18 and a door panel 19, and the corrected purlins can be collected in a unified manner by utilizing the material collecting box 18, thereby reducing the number of manpower and operation steps.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
