[0032] Embodiment 1

[0033] As shown in the attached Figure 1 description of the specification, this utility model describes a heliostat transport flatbed truck, which includes a connection seat 1, a traction frame 2, a flatbed truck frame 3, and a plurality of heliostat fixing seats 4 arranged in a staggered order on the flatbed truck frame 3; one end of the traction frame 2 is connected to the flatbed truck frame 3, and the other end is rotatably connected to the connection seat 1, and the connection seat 1 is connected to the head of the heliostat transport flatbed truck.

[0034] The heliostat transport flatbed truck further includes leaf springs, axles and wheels arranged at the bottom of the flatbed truck frame 3.

[0035] Specifically, the rear end of the traction frame 2 is connected to the front bottom of the flatbed truck frame 3 by welding or bolts. It should be noted that the front and rear are referenced based on the head and tail directions of the whole heliostat transport flatbed truck, with the head being the front and the tail being the rear.

[0036] The traction frame 2 is hinged to the connection seat 1, and the rotation direction of the hinge is axial rotation around the vertical direction, and the rotation angle range of the hinge is adjustable.

[0037] The heliostat is installed on the top of the heliostat fixing seat 4. The number of heliostat fixing seats 4 is n + 2, where n is a natural number. The heliostat fixing seats 4 have at least two types: the first height and the second height. Each heliostat fixing seat is arranged in a staggered order of high and low, or increasing, or decreasing. The horizontal distance between two adjacent heliostat fixing seats 4 is greater than 1 / 2 of the heliostat length, and the longitudinal distance between the heliostat installation surfaces at the tops of two adjacent heliostat fixing seats 4 is greater than the thickness of the heliostat. Preferably, the horizontal distance between two adjacent heliostat fixing seats 4 is greater than 1 / 2 of the heliostat length and less than the heliostat length.

[0038] It should be noted that in this embodiment, the heliostat is equipped with a heliostat support structure, and the bottom of the heliostat support structure is connected to the top of the heliostat fixing seat 4. Therefore, the thickness of the heliostat in this embodiment includes the thickness of the heliostat support structure.

[0039] As shown in the attached Figure 2 , Figure 2 in the manual, L1 represents the lateral distance between two adjacent heliostat fixing seats 4, L2 represents the length of the heliostat, and H represents the longitudinal distance between the heliostat mounting surfaces at the tops of two adjacent heliostat fixing seats 4.

[0040] At least two heliostat fixing seats 4 are provided on the flatbed vehicle frame 3.

[0041] In this embodiment, as shown in the attached Figure 3 in the manual, on the flatbed vehicle frame 3 with a length of 7280 mm, three heliostat fixing seats 4 are provided. The three heliostat fixing seats 4 are arranged at intervals in a single row along the front-back direction of the flatbed vehicle frame 3. The three heliostat fixing seats 4 have a first height and a second height. The heliostat fixing seats 4 with the first height and the heliostat fixing seats 4 with the second height are arranged at intervals and alternately in a single row along the length direction of the flatbed vehicle frame 3. The heights of the heliostat fixing seats 4 at the front and rear ends of the flatbed vehicle frame 3 are higher than the height of the heliostat fixing seat 4 in the middle. The heliostat in the middle is located below two adjacent heliostats. The heliostats at the front and rear ends respectively extend beyond the front and rear ends of the flatbed vehicle frame 3. The overall structure of the heliostat installation layout is compact.

[0042] In another implementation, the three heliostat fixing seats 4 have three heights, and the heights of the three heliostat fixing seats 4 can be arranged at intervals in a single row along the front-back direction of the flatbed vehicle frame 3 in an increasing, decreasing, or alternating high-low manner according to the needs of the transportation road conditions.

[0043] The heliostat fixing seats 4 with two heights are arranged in a staggered high-low pattern. In the case of limited vehicle loading space, the heliostats can be arranged more compactly, reducing the gaps and improving the loading efficiency. The relatively higher heliostats at the front and rear can make full use of the height space of the carriage, while the relatively lower heliostat in the middle can be placed in a relatively low position, avoiding wasting the vertical space of the flatbed truck. During transportation, it is crucial to keep the center of gravity of the vehicle frame stable. By setting the heliostat fixing seats at the front and rear ends higher and the heliostat fixing seat in the middle lower, the center of gravity distribution of the whole vehicle can be optimized, reducing the sway of the vehicle during transportation and ensuring the stability of transportation. This structural distribution is applicable to scenarios that require long-distance transportation and relatively complex road conditions, especially in situations where it is necessary to control the vehicle's center of gravity to maintain stability, such as transportation on mountain roads or roads with a certain slope.

[0044] The heliostat fixing seats 4 with two or more heights are arranged in a staggered manner with increasing heights. This can not only increase the loading capacity, unload in sequence, and simplify the unloading process, but also make the transportation of the heliostats more aerodynamic and reduce the wind resistance during driving. In addition, when the vehicle is going uphill, the arrangement with increasing heights can keep the higher heliostats at the rear of the vehicle at a higher position, effectively avoiding the risk of the heliostats contacting the road surface due to the road slope. It is applicable to the scenario of transporting heliostats under road conditions with uphill slopes or large wind resistance.

[0045] The heliostat fixing seats 4 with two or more heights are arranged in a staggered manner with decreasing heights. Similar to the arrangement with increasing heights, it can increase the loading capacity, unload in sequence, and simplify the unloading process. In addition, the heliostats located in the front, due to being at a higher position, contribute to maintaining the balance and stability of the vehicle body when going downhill, enhancing driving safety. It is applicable to the transportation scenario with more downhill sections.

[0046] The heliostat fixing seats 4 with two or more heights are arranged in a staggered high-low pattern. The applicable transportation scenarios are the same as those for the heliostat fixing seats 4 with two heights arranged in a staggered high-low pattern. It can optimize the center-of-gravity distribution of the entire vehicle, reduce the swaying of the vehicle during transportation, and ensure the stability of transportation. It is applicable to the transportation environment with complex terrains, frequent turning requirements, or uneven road surfaces.

[0047] With the structure of this embodiment, multiple heliostat fixing seats 4 are arranged in a staggered pattern of high-low, increasing heights, or decreasing heights on the top surface of the flatbed frame 3, so that the heliostats are fixed to the heliostat fixing seats 4 in a staggered manner, saving transportation space, improving the transportation efficiency of the heliostat transport flatbed vehicle, and meeting the requirements of different transportation scenarios.

[0048] Embodiment 2

[0049] Referring to the attached drawings of the specification Figure 4 This embodiment includes all the structures of Embodiment 1. The connecting seat 1 includes a first connecting bracket 10, a second connecting plate 11, and bolts 12.

[0050] The second connecting plate 11 includes two arc plates arranged parallel up and down. A plurality of vertically communicating adjustment holes are spaced apart on the inner side of the arc surfaces of the two arc plates. An articulated shaft is arranged between the two arc plates. The front end of the towing frame 2 is located between the two arc plates and is hinged to the second connecting plate 11 through the articulated shaft, enabling the towing frame 2 to rotate around the articulated shaft.

[0051] There are 2 bolts 12. The 2 bolts 12 pass through the adjustment holes of the two arc plates and are locked by corresponding nuts. The bolts 12 are hexagon flange face bolts. The 2 bolts are located on both sides of the towing frame 2.

[0052] The second connecting plate 11 further includes side plates connected to the two arc plates. The second connecting plate 11 is connected to the first connecting bracket 10 through the side plates, and the connection method can be welding. The first connecting bracket 10 is connected to the head of the heliostat transport flatbed truck.

[0053] With the structure of this embodiment, by adjusting the relative distances between the two bolts 12 and both sides of the towing frame 2, the turning angle of the heliostat transport flatbed truck can be limited, that is, the rotation angle of the head relative to the flatbed frame 3 is limited, avoiding interference between the head and the heliostat.

[0054] Embodiment 3

[0055] Refer to the attached drawings of the specification Figure 5 , on the basis of Embodiment 1, the heliostat transport flatbed truck further includes shock-absorbing pads 5. The number of shock-absorbing pads 5 corresponds to the number of heliostat fixing seats 4. The shock-absorbing pads 5 are arranged between the bottom of the heliostat fixing seats 4 and the top surface of the flatbed frame 3.

[0056] The shock-absorbing pads 5 are made of rubber material.

[0057] Specifically, mounting holes are provided around the bottom of the heliostat fixing seat 4, and the shock-absorbing pads 5 are matched with the bottom surface of the heliostat fixing seat 4. The heliostat fixing seat 4 and the shock-absorbing pads 5 are installed on the flatbed frame 3 through fasteners.

[0058] With the structure of this embodiment, the shock absorption and buffering during the transportation of the heliostat are realized through the shock-absorbing pads 5.

[0059] For the heliostat transport flatbed truck of the present utility model, through the staggered arrangement of the heliostat fixing seats, the space utilization rate of the flatbed frame is improved, and the transportation efficiency of the heliostat is improved. Through the connecting seat, the rotation angle limitation adjustment between the head and the flatbed frame is realized, avoiding interference between the head and the foremost heliostat when the head turns.
