Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0023] like Figure 1 and Figure 2As shown, a lifting device for transporting photovoltaic brackets includes a crossbar 1, a first clamping unit 2, and a second clamping unit 3. The top of the crossbar 1 is provided with a lifting lug 11; The first clamping unit 2 includes a movable support rod 21 and two clamping parts 22. A slot is provided in the middle of the movable support rod 21, and the movable support rod 21 is clamped on the crossbar 1 through the slot, so that the movable support rod 21 can slide along the long axis of the crossbar 1. The long axis of the movable support rod 21 is perpendicular to the long axis of the crossbar 1. The two clamping parts 22 are movably arranged at both ends of the movable support rod 21 along the length direction of the movable support rod 21, so as to adjust the distance between the two clamping parts 22. The second clamping unit 3 has the same structure as the first clamping unit 2. The movable support rod 21 of the second clamping unit 3 is clamped on the crossbar 1 through a slot, and the movable support rod 21 of the second clamping unit 3 can slide along the long axis of the crossbar 1. The clamping parts 22 of the first clamping unit 2 and the second clamping unit 3 are used to clamp the four corners of the photovoltaic bracket respectively.

[0024] When using this device (a lifting device for transporting photovoltaic brackets), the device is installed on the lifting device via the lifting lugs 11. When clamping the photovoltaic bracket, the movable support rod 21 is adjusted along the length of the crossbar 1. The position of the movable support rod 21 in the first clamping unit 2 and the second clamping unit 3 is determined according to the length of the photovoltaic bracket. Since both clamping parts 22 are connected to the movable support rod 21, the position of the clamping parts 22 changes during the movement of the movable support rod 21. The positions of the two clamping parts 22 in the first clamping unit 2 and the two clamping parts 22 in the second clamping unit 3 are determined according to the width of the photovoltaic bracket. After the clamping parts 22 of the first clamping unit 2 and the second clamping unit 3 change position, they can correspond to the four corners of the photovoltaic bracket and clamp and fix it, so as to make the transport of the photovoltaic bracket more convenient. When hoisting photovoltaic brackets of various sizes, it is only necessary to adjust the distance between the first clamping unit 2 and the second clamping unit 3, as well as the distance between the two clamping parts 22 in the first clamping unit 2 and the second clamping unit 3, thereby improving the transfer efficiency of the photovoltaic brackets.

[0025] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the movable support rod 21 is provided with a locking plate 4, and the locking plate 4 is provided with a locking groove corresponding to the position of the crossbar 1. In this embodiment, the cross-sectional shape of the crossbar 1 is "convex", and the cross-sectional shape of the locking groove matches the cross-sectional shape of the crossbar 1, so that the movable support rod 21 can be locked on the crossbar 1 through the locking groove and slide along the length direction of the crossbar 1.

[0026] Preferably, the crossbar 1 is provided with a plurality of connecting holes 12, specifically: the connecting holes 12 are provided at the steps on both sides of the crossbar 1, and the plurality of connecting holes 12 are arranged along the length direction of the crossbar 1; The card plate 4 has a through hole on the side of the crossbar 1 where the connecting hole 12 is provided. When the movable support rod 21 slides to the designated position on the crossbar 1, a bolt is used to pass through the through hole and insert into the connecting hole 12 to fix the movable support rod 21 relative to the crossbar 1. This prevents the position of the movable support rod 21 from changing after hoisting, and eliminates the need to adjust the position of the movable support rod 21 again. This makes the use of the device more convenient and improves the stability of the device.

[0027] like Figure 1 and Figure 4 As shown, in a preferred embodiment, limiting blocks 5 are provided at both ends of the crossbar 1. In this embodiment, the movable support rod 21 needs to move along the length direction of the crossbar 1. At this time, limiting blocks 5 are added at both ends of the crossbar 1 to prevent the movable support rod 21 from sliding off from both sides of the crossbar 1.

[0028] like Figure 3 As shown, in a preferred embodiment, the clamping part 22 includes a slide bar 221, a first clamping plate 222, and a second clamping plate 223; The movable support rod 21 is a tubular structure, and the inner cavity of the movable support rod 21 is a through hole 211; One end of the slide rod 221 is slidably disposed in the through hole 211, and the other end is provided with a fixed support rod 224 perpendicular to the slide rod 221; the first clamping plate 222 is vertically disposed on one side of the fixed support rod 224, and the second clamping plate 223 has the same structure as the first clamping plate 222 and is vertically disposed on the other side of the fixed support rod 224; the first clamping plate 222 and the second clamping plate 223 move toward the middle of the fixed support rod 224 to clamp the photovoltaic bracket.

[0029] In this embodiment, the relative position of the two clamping parts 22 can be adjusted by pulling or pushing the slide bar 221 to adapt to photovoltaic brackets of different widths.

[0030] like Figure 3 As shown, in a preferred embodiment, the side wall of the slide rod 221 is further provided with a pulley 6, and the slide rod 221 slides within the through hole 211 via the pulley 6. In this embodiment, the pulley 6 is provided on the side wall of the slide rod 221 to reduce the friction between the slide rod 221 and the movable support rod 21 by converting sliding friction into rolling friction, thereby making the sliding of the slide rod 221 smoother.

[0031] like Figure 3As shown, in a preferred embodiment, the bottom of the fixed support rod 224 is provided with a groove 225, the long axis of the groove 225 is parallel to the long axis of the fixed support rod 224, and a movable bolt 226 is rotatably arranged in the groove 225. The two ends of the movable bolt 226 protrude from the two ends of the fixed support rod 224 respectively. The threads on the portions of the movable bolt 226 corresponding to the two sides of the slide rod 221 have opposite directions. The top of the first clamping plate 222 and the second clamping plate 223 are each provided with a slider 227. The two sliders 227 are respectively screwed to the two sides of the movable bolt 226 corresponding to the slide rod 221. By rotating the movable bolt 226, the first clamping plate 222 and the second clamping plate 223 can move towards the middle of the movable bolt 226 simultaneously to clamp the photovoltaic bracket; or they can move away from the two sides of the movable bolt 226 corresponding to the slide rod 221 simultaneously to release the photovoltaic bracket.

[0032] In this embodiment, when adjusting the first clamping plate 222 and the second clamping plate 223, the operator rotates the movable bolt 226; since the slider 227 is screwed to the movable bolt 226, the two sliders 227 move along the axis of the movable bolt 226 towards the midpoint of the movable bolt 226 in the groove 225, and the first clamping plate 222 and the second clamping plate 223 come together to clamp the photovoltaic bracket.

[0033] like Figure 2 As shown in the preferred embodiment, the side wall of the slide rod 221 is provided with a plurality of limiting holes 228 along the length direction; it also includes a pin 229, the insertion end of which can extend into the through hole 221 and be inserted into the corresponding limiting hole 228, so as to realize the relative fixation of the slide rod 221 and the movable support rod 21, and prevent the position of the slide rod 221 from changing during the clamping process.

[0034] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a spring 230 is provided inside the through hole 211. The spring 230 is sleeved on the pin 229, and both ends of the spring 230 are connected to the side wall of the through hole 211 and the side wall of the pin 229, respectively. In this embodiment, when the slide rod 221 needs to move, the operator pulls the pin 229 outward. At this time, the pin 229 disengages from the limiting hole 228, and the spring 230 is compressed. After the position of the slide rod 221 is adjusted, the operator releases the pin 229, and the spring 230 returns to its initial state. The deformation of the spring 230 causes the pin 229 to insert into the limiting hole 228, thereby fixing the slide rod 221 and the movable support rod 21 relatively.

[0035] like Figure 3 As shown, in a preferred embodiment, the end of the pin 229 is provided with a handle 231. In this embodiment, the handle 231 at the end of the pin 229 facilitates the movement of the pin 229 by the operator.

[0036] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.

[0037] In the description of this utility model, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., are used only to indicate the orientation or positional relationship for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.
