Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel frame conveying, and more specifically, to a loading and conveying device applied to photovoltaic panel frames. Background Art

[0002] In the current photovoltaic industry, the loading and transportation of photovoltaic panel frames is an important link. However, the existing photovoltaic panel frame loading and transportation devices have some obvious limitations. The most prominent problem is that during use, the operator needs to firmly fix the frame on the conveying device to ensure the safety and stability of the transportation process. However, most of the conveying devices on the market currently adopt a fixed angle design. This structure increases the difficulty of fixing the frame. Operators often need to spend more time and energy to adjust the position of the frame so that it can match the fixed angle of the conveying device. This not only reduces work efficiency, but may also bring safety hazards due to improper fixation.

[0003] In addition to the problems caused by angle fixation, the existing photovoltaic panel frame loading and conveying equipment also has deficiencies in the fixing method. Most equipment lacks a flexible and fast fixing mechanism, which makes it inconvenient for operators to fix the frame. This design defect not only increases the labor intensity of workers, but also prolongs the time required for the entire loading process. In addition, due to the inconvenience of fixing, the frame may become loose or shifted during the transportation process, affecting the safety of transportation. Summary of the invention

[0038] Working principle: When installing the frame body 28, it is necessary to rotate the flip plate 5 along the rotating sleeve 4 according to the installation situation so that the frame body 28 can slide conveniently on the flip plate 5. When sliding downward, the inner magnetic block 12 is away from the magnetic suction block 9, and the thrust of the push spring 18 is greater than the thrust of the return spring 13. The push spring 18 drives the expansion rod 19 to contact the outer expansion rod 14, and then drives the outer expansion rod 14 to expand outward along the telescopic hole 16, and then makes the inner magnetic block 12 move outward accordingly. After the installation of the frame body 28 is completed, the handle 17 is driven to pull upward. At this time, do not pinch on the expansion rod 19. When the telescopic hole 16 and the transverse hole 15 are rotated to be coaxial, the magnetic force of the inner magnetic block 12 on the magnetic suction block 9 at this distance is greater than the magnetic force of the outer magnetic block 7 on the magnetic suction block 9. Therefore, it will drive the stop rod 10 to slide toward the telescopic hole 16. As long as the magnetic force of the inner magnetic block 12 is greater than the magnetic force of the outer magnetic block 7 The more it contacts the inner magnetic block 12, the greater the adsorption force will be, and then the stop rod 10 will be inserted into the telescopic hole 16, limiting the follower rod 3 and the vertical rod 2. At this time, the magnetic block 9 contacts the stop ring 11, thereby ensuring the fixing effect. When the connection between the stop rod 10 and the telescopic hole 16 is required, it is pinched on the expansion rod 19, and then the push spring 18 is compressed. At this time, the thrust of the return spring 13 is greater than the suction force between the magnetic block 9 and the inner magnetic block 12, and then the expansion rod 14 shrinks inward, and the inner magnetic block 12 shrinks inward synchronously. When the distance increases, the suction force between the inner magnetic block 12 and the magnetic block 9 decreases. When the suction force between the inner magnetic block 12 and the magnetic block 9 is less than the suction force between the outer magnetic block 7 and the magnetic block 9, the suction force of the outer magnetic block 7 on the magnetic block 9 will pull the magnetic block 9 to move backward. Since the distance between the outer magnetic block 7 and the magnetic block 9 is reduced, the suction force increases, and then it is ensured that the magnetic block 9 is in a stable and fixed state in the transverse hole 15.

[0039] When it is necessary to adjust the initial distance between the outer magnetic block 7 and the magnetic block 9, the distance between the screw 8 and the outer magnetic block 7 can be changed by rotating the screw 8. Each time the magnetic block 9 returns, the magnetic block 9 will contact the screw 8, thereby ensuring the initial position of the magnetic block 9. If the initial position distance between the magnetic block 9 and the outer magnetic block 7 is too close, the suction force between the inner magnetic block 12 and the magnetic block 9 will be too small, thereby affecting the disengagement process. Therefore, the initial position of the magnetic block 9 can be adjusted by the screw 8, thereby ensuring the convenience of disengagement. By moving the two ends of the magnetic block 9, the convenience of adjusting the flip plate 5 up and down each time can be conveniently guaranteed, thereby ensuring the effect of use.

[0040] In order to fix the frame, add a fixing mechanism, please refer to Figure 7-9The fixing mechanism includes a fixing seat 22, an inclined plate 23, a follower block 24, a lower pressure spring 25 and a lower pressure plate 26. The fixing seat 22 is installed on the flip plate 5. An inclined groove 27 is provided on the fixing seat 22. The inclined plate 23 is slidably connected in the inclined groove 27. The follower block 24 is installed on the inclined plate 23, and the upper end surface of the follower block 24 and the flip plate 5 are arranged in parallel. There are two lower pressure springs 25, and the two ends of the two lower pressure springs 25 are respectively connected to the follower block 24 and the lower pressure plate 26. A frame body 28 is provided on the flip plate 5. The side wall of the follower block 24 abuts against the side wall of the frame body 28, and the lower pressure plate 26 is pressed on the frame body 28. A fixing sleeve 29 is provided on the fixing seat 22. A protruding rod 30 is slidably provided in the fixing sleeve 29. The protruding rod 30 is provided with a connecting spring 31. The connecting spring 31 is connected to the follower block 24, and the protruding rod 30 and the inclined groove 27 are arranged in parallel. A plurality of contraction grooves 32 are provided on the inner wall of 9, and a contraction block 33 is slidably provided on each contraction groove 32, and two guide rods 34 are slidably provided on each contraction block 33, and a fitting plate 35 is provided on the two guide rods 34, and a spring 36 is provided on the fitting plate 35, and the other end of the spring 36 is connected to the contraction block 33, and a plurality of one-way blocks 37 are evenly spaced on the fitting plate 35, and a spiral groove 38 is provided on the side wall of the extension rod 30, and the plurality of one-way blocks 37 are respectively stuck in the spiral groove 38, and a top spring 39 and an external plate 40 are respectively provided on each contraction block 33, and the plurality of top springs 39 are respectively abutted in the fixed sleeve 29, and each external plate 40 is respectively provided with a receiving spring 41, and the plurality of receiving springs 41 are respectively connected with a synchronous sleeve 42, and the synchronous sleeve 42 is slidably connected to the fixed sleeve 29, and a push plate 43 is coaxially provided on the extension rod 30, and a rotating block 44 is provided on the push plate 43.

[0041] Working principle: After the frame body 28 is placed on the flip plate 5, it needs to be fixed. The connecting spring 31 applies a thrust to the follower block 24, and then the inclined plate 23 on the follower block 24 will slide along the inclined groove 27, and then the follower block 24 moves downward. At this time, the follower block 24 is in the process of sliding downward and extending outward. At this time, the lower pressure plate 26 is first pressed on the frame body 28, and a certain fixing force is applied by the lower pressure spring 25. At this time, the lower pressure plate 26 is in a fixed state, and the lower pressure spring 25 is in a continuous compression state. Then the follower block 24 continues to slide downward and contacts the side wall of the frame body 28, thereby fixing the frame body 28. At this time, the frame is not only fixed horizontally but also fixed in the vertical direction, thereby ensuring the stability of the fixation, and then ensuring the safety of the frame transportation.

[0042] When the position of the connecting spring 31 needs to be adjusted, the extending rod 30 is first slidably connected to the fixing sleeve 29 and then pressed downward. At this time, the contraction block 33 will slide and contract along the contraction groove 32 under the action of the top spring 39. Then, after pressing downward to the corresponding position, the synchronous sleeve 42 is pulled upward. Under the action of the receiving spring 41, the multiple contraction blocks 33 will be pulled upward, and then the multiple one-way blocks 37 are respectively inserted into the spiral groove 38, thereby ensuring the threaded connection of the multiple one-way blocks 37 and the spiral groove 38. At this time, the fitting plate 35 also contacts the side wall of the extending rod 30, thereby ensuring the convenience of insertion and fixing. Because the extending rod 30 is pushed back under the action of the connecting spring 31, the contraction block 33 and the contraction groove 32 are in a contracted state, so the reverse stop is guaranteed, thereby ensuring unidirectional movement. When a small force fixation is required, only these two steps are needed. Pressing down and pulling the synchronous sleeve 42 can complete the clamping process.

[0043] When strong fixing is required, the one-way block 37 and the spiral groove 38 are threadedly connected, and it is only necessary to drive the rotating block 44 to rotate with a wrench, so that multiple extension rods 30 can continue to press downward, thereby ensuring the continuous generation of pressure, and then ensuring the fixing effect. When it is necessary to unlock, the push plate 43 and the synchronous sleeve 42 are pressed simultaneously, which will cause the one-way block 37 to unlock the connection with the spiral groove 38. At this time, the synchronous sleeve 42 should not be loosened. The push plate 43 should be loosened first, the extension rod 30 can be pulled out, and then the synchronous sleeve 42 is loosened to complete the adjustment process.

[0044] See also Figure 6 and Figure 10-11 In order to realize multiple fixation of the frame, a pressing mechanism is added, which includes a clamping sleeve 45, a two-way rod 46 and a two-way spring 47. A plurality of adjustment holes 48 are evenly spaced on the flip plate 5. The clamping sleeve 45 is slidably connected in the adjustment hole 48. A plurality of two-way holes 49 are symmetrically opened at the upper and lower ends of the clamping sleeve 45. A two-way rod 46 is slidably connected in each two-way hole 49. A two-way spring 47 is sleeved in each two-way rod 46. A plurality of middle grooves 50 are evenly spaced in the clamping sleeve 45. The two ends of the two-way spring 47 are respectively against the two sides of the middle groove 50. The rods 46 are respectively clamped on both sides of the flip plate 5, and a plurality of connecting rods 51 are evenly spaced on the upper end surface of the clamping sleeve 45. A pressure plate 52 is provided on the plurality of connecting rods 51. The pressure plate 52 is pressed on the upper end surface of the frame body 28. An intermediate rod 53 is coaxially slidably provided on the pressure plate 52. A contact head 54 is respectively provided on each bidirectional rod 46, and two expansion sleeves 55 are provided on the intermediate rod 53. The two expansion sleeves 55 respectively abut against the plurality of contact heads 54, and an annular groove 56 is opened on the side walls of the two expansion sleeves 55. A stop plate 57 is coaxially provided on the intermediate rod 53, and a grip is provided on the stop plate 57.

[0045] Working principle: When it is necessary to fix the pressure plate 52 on the frame body 28, first press the pressure plate 52 on the frame body 28, and then insert the clamping sleeve 45 into the most suitable adjustment hole 48, then press the holding plate 58, the expansion sleeve 55 will make it slide downward, and then the contact head 54 will press on the expansion sleeve 55, and then make multiple two-way rods 46 expand outward, thereby ensuring that the two-way rods 46 on both sides are respectively stuck on both sides of the flip plate 5, and then make the contact head 54 press on the annular groove 56, thereby completing the fixation of the two-way rod 46, and then ensuring the fixation of the frame body 28, when it is necessary to release the connection, just pull the holding plate 58 upwards to release the connection between the annular groove 56 and the contact head 54, thereby completing the release process.
