Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket processing technology, and in particular to a structural lifting tool for photovoltaic brackets. Background Technology

[0002] Common structural components used in photovoltaic (PV) mounting systems include rectangular tubes, C-shaped tubes, and other pipe fittings. These fittings are typically cut into sections using punching or sawing methods, and then bundled for transfer, loading, or stacking. Existing transfer lifting equipment is relatively simple, using a pair of straps attached to both ends of the bundled fittings. The straps are connected to a crossbar, which is then hooked onto a crane hook. This type of lifting equipment is inconvenient for attaching the straps, the straps are prone to breakage, and the straps cannot secure the upper-level fittings during transfer. Therefore, if the crossbar tilts slightly during transfer, the fittings can easily slip off. Utility Model Content

[0003] This utility model provides a structural component lifting tool for photovoltaic brackets to overcome the shortcomings of the prior art, facilitate the transfer and transportation of pipe components, and ensure safety during the transfer and transportation process, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A lifting device for photovoltaic support structures includes a channel-shaped crossbar with end rods installed at both ends. A concave plate is provided on each end rod, and a vertical rod is installed at the lower end of the concave plate. An upper pull seat is installed at the lower end of the vertical rod, and multiple connecting rods pass through the upper pull seat. An end cap is provided at the upper end of each connecting rod. An upper pull horizontal plate is installed at the lower end of each connecting rod at the same end. Vertical plates are provided at both ends of the upper pull horizontal plate, and a folded plate is formed at the lower end of each vertical plate. An L-shaped insert plate is provided on the inner wall of the lower end of the folded plate, and a sleeve is fitted onto the L-shaped insert plate. A concave bottom plate is installed between the sleeves at the same end. When placing pipe fittings, the fittings can be placed directly on the concave bottom plate, provided that the concave bottom plate is positioned according to predetermined requirements beforehand. After the fittings are stacked, the L-shaped insert plate can be inserted into the sleeve, and then the fittings can be transferred by lifting.

[0006] Furthermore, the two ends of the end rod are fixed to the grooved crossbar with nuts, and the concave plate can also be limited by the outer nuts to prevent the concave plate from falling off.

[0007] Furthermore, a hanging rod is provided at the middle position along the length of the channel-shaped crossbar, which facilitates the fixing of the traction rope on the vehicle to the channel-shaped crossbar.

[0008] Furthermore, in order to ensure the stability of the L-shaped insert after insertion and the safety during transfer, capped pins are installed on both sides of the L-shaped insert. A spring is fitted on the outer end of the capped pin, and an inner top plate is fitted on the inner end of the spring. The inner top plate is fitted on the capped pin, and a pin is provided at the upper end of the inner top plate. The inner end of the pin is located on the side wall of the insert.

[0009] Furthermore, in order to limit and constrain the upper pipe fittings, an action rod is provided at each end of the upper pull seat, and a hinge seat is installed at each end of the upper pull horizontal plate. A rotating plate is rotatably provided on the hinge seat, and a hinge shaft is provided at the upper end of the hinge seat. The rotating plate is rotatably mounted on the hinge shaft. An oblong hole is opened at the inner end of the rotating plate, and an end elongated hole is opened at the inner end of the rotating plate. A through rod is passed through the end elongated hole, and a pair of upper pull plates are provided on the through rod. The upper pull plates are passed through the upper pull horizontal plate, and a lower pressure plate is installed at the lower end of the upper pull plate. A pair of connecting screws are provided at the outer end of the lower pressure plate. A pair of guide elongated holes are opened on the vertical plate, and the connecting screws are passed through the guide elongated holes. A limiting outer plate is provided at the outer end of each pair of connecting screws, and the limiting outer plate is located outside the vertical plate.

[0010] Furthermore, to prevent the pipe fittings from slipping off from both ends, a hanging plate is provided on the outer wall of the vertical plate. A limiting end plate is provided on the outer end of the hanging plate, and a connecting arm is provided on the hanging plate. An end baffle is provided on the outer end of the connecting arm, and the lower wall of the limiting outer plate acts on the upper side of the connecting arm.

[0011] Furthermore, in order to reduce the weight of the lifting device, multiple holes are provided on the end baffle.

[0012] The advantages of the above technical solution are:

[0013] This invention facilitates the transfer of multiple neatly stacked pipe fittings and ensures safety during the transfer to prevent them from falling. Attached Figure Description

[0019] A concave plate 2 is provided on the end rod 10. A vertical rod 200 is installed at the lower end of the concave plate 2. An upper pull seat 20 is installed at the lower end of the vertical rod 200. Multiple connecting rods 21 are passed through the upper pull seat 20. An end cap is provided at the upper end of the connecting rod 21. An upper pull horizontal plate 29 is installed at the lower end of the connecting rod 21 located at the same end. Vertical plates 30 are provided at both ends of the upper pull horizontal plate 29. A folded plate 38 is formed at the lower end of the vertical plate 30. An L-shaped insert plate 39 is provided on the inner wall of the lower end of the folded plate 38. An insert sleeve 40 is fitted on the L-shaped insert plate 39. A concave bottom plate 42 is installed between the insert sleeves 40 located at the same end. The L-shaped insert plate 39 is equipped with capped pins 43 on both sides. A spring 44 is sleeved on the outer end of the capped pin 43. An inner top plate 7 is provided on the inner end of the spring 44. The inner top plate 7 is sleeved on the capped pin 43. A pin 41 is provided at the upper end of the inner top plate 7. The inner end of the pin 41 is located on the side wall of the insert sleeve 40.

[0020] Each end of the upper pull seat 20 is provided with an actuating rod 210. Each end of the upper pull horizontal plate 29 is provided with a hinge seat 24. A rotating plate 22 is rotatably provided on the hinge seat 24. A hinge shaft 26 is provided at the upper end of the hinge seat 24. The rotating plate 22 is rotatably provided on the hinge shaft 26. An oblong hole 23 is opened at the inner end of the rotating plate 22. An elongated hole 25 is opened at the inner end of the rotating plate 22. A through rod 27 is passed through the elongated hole 25. A pair of upper pull plates 28 are provided on the through rod 27. The upper pull plates 28 are passed through the upper pull horizontal plate 29. A lower pressure plate 34 is installed at the lower end of the upper pull plate 28. A pair of connecting screws 32 are provided at the outer end of the lower pressure plate 34. A pair of guide holes 31 are opened on the vertical plate 30. The connecting screws 32 are passed through the guide holes 31. A limiting outer plate 33 is provided at the outer end of each pair of connecting screws 32. The limiting outer plate 33 is located outside the vertical plate 30. A hanging plate is provided on the outer wall of the vertical plate 30. A limiting end plate 35 is provided on the outer end of the hanging plate. A connecting arm 36 is provided on the hanging plate.

[0021] In this embodiment, the operator places the concave base plate 42 according to the predetermined width. If necessary, a pair of limiting parts made of channel steel can be fixed at the material placement area. When placing the pipe fittings, the concave base plate 42 can be placed inside the channel steel first.

[0022] Next, the operator moves the trough-shaped crossbar 1 above the pipe stack using a crane, so that the L-shaped insert plate 39 is located on the side below the insert sleeve 40.

[0023] Then, the L-shaped insert 39 is moved by the crane so that it is positioned directly below the insert 40.

[0024] The operator then hooks the inner end of the connecting arm 36 onto the hanging plate.

[0025] Finally, the tractor pulls the slotted crossbar 1 and the upper pull seat 20 upward again. When the upper pull seat 20 moves upward, the rotating plate 22 will rotate through the action of the action rod 210. As the rotating plate 22 rotates, it will act on the through rod 27 through the end elongated hole 25, thereby causing the upper pull plate 28 and the lower pressure plate 34 to move downward. Finally, the lower pressure plate 34 acts on the upper layer of the pipe fitting. At the same time, as the lower pressure plate 34 moves, the lower wall of the limiting outer plate 33 will act on the upper side of the connecting arm 36.

[0026] Then continue to pull the upper pull seat 20 upwards until it can no longer move. After that, the operator will put the inner top plate 7 on the pin 41 and carry out the pipe transfer operation.
