Description

Technical Field

[0001] This utility model relates to the field of photovoltaic grid transportation technology, and in particular to a truss unit transfer tool. Background Technology

[0002] Truss units are part of the photovoltaic steel structure grid. Multiple truss units are welded and fixed together to form the photovoltaic steel structure grid. After manufacturing, multiple truss units are transported to the construction site for welding and assembly before use. Currently, most truss units are long, strip-shaped lattice steel structures with thin members, large spans, and weak bending and torsional resistance. They are easily damaged and have their paint chipped during transportation. The lattice structure of the trusses makes it impossible to stack or nest them tightly during transportation, and the transport capacity of a single vehicle is limited. Currently, truss units are often stacked in multiple layers during transportation, which can easily cause the members of the lower-layer truss units to bend, affecting subsequent use. Utility Model Content

[0003] To address the problem that current methods of directly stacking multiple truss units during transportation can easily lead to bending of the members in the lower truss units, this invention proposes a truss unit transfer fixture that can arrange multiple truss units longitudinally on the transfer fixture, increasing the loading capacity of a single transport while preventing the truss units from being bent.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A truss unit transfer fixture includes a connecting bracket and two fixed brackets fixed on both sides of the connecting bracket. The fixed brackets are used to place multiple truss units. The fixture is characterized in that the fixed bracket includes two opposing fixed plates and a support plate connecting the two fixed plates. The upper sides of the two fixed plates are respectively provided with placement plates. The placement plates extend longitudinally and have multiple first placement slots and second placement slots. The first placement slots and second placement slots are spaced apart, and the bottom surface of the first placement slot is higher than the bottom surface of the second placement slot, so that two adjacent truss units placed on the placement plate are staggered in height.

[0006] Preferably, the longitudinal sections of the first and second placement slots are both U-shaped, and when the truss unit is placed on the placement plate, it contacts the inner surfaces of the first and second placement slots.

[0007] Preferably, the inner surfaces of the first and second placement grooves are fixed with a layer structure made of rubber.

[0008] Preferably, the fixing bracket is I-shaped.

[0009] Preferably, the connecting bracket includes two opposing horizontal first connecting rods and a second connecting rod connecting the two first connecting rods, with the end of the second connecting rod fixedly connected to the fixed bracket.

[0010] Preferably, the truss unit includes two opposing first trusses and a second truss connecting the two first trusses, with the upper first truss and the lower first truss respectively placed on corresponding placement plates of the upper and lower fixed plates.

[0011] Through the above technical solution, the beneficial effects of this utility model are as follows: In this utility model, the longitudinally extending placement plate is provided with a plurality of first placement slots and second placement slots. The first placement slots and second placement slots are spaced apart, and the bottom surface of the first placement slot is higher than the bottom surface of the second placement slot. This causes the adjacent two truss units placed on the placement plate to be staggered in height, increasing the loading capacity of a single vehicle transport. At the same time, the truss units can extend longitudinally on the placement plate, and the lower truss unit will not be bent, reducing the loss rate during the transfer process.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1-3 As shown, this embodiment provides a truss unit transfer fixture, including a connecting bracket 1. The connecting bracket 1 includes two opposing horizontal first connecting rods 11 and a plurality of second connecting rods 12 connecting the two first connecting rods 11. The second connecting rods 12 can be vertical or inclined, and are used to improve the structural strength of the connecting bracket 1. Each first connecting rod 11 has a flange plate 13 at both ends.

[0018] Fixed brackets 2 are provided on both the left and right sides of the connecting bracket 1. The sum of the lengths of the connecting bracket 1 and the two fixed brackets 2 is the length of the transfer fixture, which is 7.68m. The fixed bracket 2 includes two vertically opposite fixed plates 21 and a vertical support plate 22 connecting the two fixed plates 21. The two fixed plates 21 and the support plate 22 are connected to form an I-shape. The lower side of the fixed plate 21 is the placement surface, which is placed on the bottom of the transfer vehicle or on the ground. In this embodiment, the transfer vehicle is a flatbed car with a minimum length of 21m.

[0019] Furthermore, each of the two fixing plates 21 is provided with a connecting seat 24 on the side near the connecting bracket 1. The connecting seat 24 is located in the middle of the fixing plate 21. The side of the connecting seat 24 near the connecting bracket 1 is also provided with a flange plate 13, which is bolted to the flange plate 13 at the end of the first connecting rod 11 to realize the connection and fixation between the fixing bracket 2 and the connecting bracket 1.

[0020] The upper sides of both fixed plates 21 are provided with placement plates 23. The height of the fixed bracket 2 plus the height of the placement plate 23 is the height of the transfer fixture, which is 3.3m. The placement plate 23 extends longitudinally, and the placement plates 23 on the upper and lower fixed plates 21 are correspondingly set. Multiple first placement slots 231 and second placement slots 232 are opened on the placement plate 23. The first placement slots 231 and second placement slots 232 are spaced apart, and the bottom surface of the first placement slot 231 is higher than the bottom surface of the second placement slot 232, so that the heights of two adjacent truss units 3 placed on the placement plate 23 are staggered, thereby increasing the number of truss units 3 that can be placed in this device.

[0021] In this embodiment, the connecting bracket 1 and the fixed bracket 2 are made of Q235B structural steel.

[0022] Furthermore, the longitudinal sections of the first placement groove 231 and the second placement groove 232 are both U-shaped and the same size. The distance between the two sides of the groove surface of the first placement groove 231 is greater than 190mm, so that when the truss unit 3 is placed in the placement groove, its side can contact the groove surface, ensuring the stability of the placement of the truss unit 3. At the same time, a rubber layer structure (not shown in the figure) can be added to the inner side of the first placement groove 231 and the second placement groove 232 to provide cushioning for the truss unit 3 and prevent the truss unit 3 from being bumped during transportation or placement.

[0023] refer to Figure 3The truss unit 3 includes two opposing first trusses 31 and multiple second trusses 32 connecting the two first trusses 31. The first trusses 31 are arranged horizontally, and the second trusses 32 can be arranged vertically or diagonally. Both first trusses 31 are placed in corresponding placement slots opened on the placement plate 23. Specifically, the multiple first placement slots 231 and second placement slots 232 opened on the upper and lower placement plates 23 are vertically corresponding. When the first truss 31 on the upper side of the truss unit 3 is placed in the first placement slot 231 on the upper placement plate 23, the first truss 31 on the lower side is also placed in the first placement slot 231 on the lower placement plate 23.

[0024] In this embodiment, the truss unit 3 is 20m long and 2.5m high, and is made of Q355C structural steel. The first truss 31 is a round bar with a diameter ranging from 120 to 190mm. In other embodiments, the first truss 31 may also be a square bar, so that the first truss 31 can be placed in the first placement slot 231 or the second placement slot 232. The weight of a single truss unit 3 is about 1.5 tons. In this embodiment, the transfer fixture can transfer 14 truss units 3 at a time.

[0025] When it is necessary to transfer the truss unit 3, first place the device on the bottom surface of the transport vehicle. The transfer tool is located in the middle of the vehicle. The device is tied and fixed in the vehicle by ropes. Then, multiple truss units 3 are hoisted into the first placement slot 231 and the second placement slot 232 of the placement plate 23 in sequence. The upper and lower first trusses 31 of the truss unit 3 are placed in the corresponding positions of the first placement slot 231 or the second placement slot 232 on the two fixed supports 2. First, place them in the first placement slot 231 closest to the side of the support plate 22, and then place them in sequence. When the placement limit of the device is reached, the truss unit 3 is fixedly connected to the vehicle by ropes. At this time, the truss unit 3 can be transported to the designated location by the transport vehicle.
