[0034] Next, reference is made to Figures 1 to 4 Describe the boom and the aerial work platform according to the embodiments of the present utility model.
[0035] Reference is made to Figures 1 to 4 As shown, the boom 10 according to the first aspect embodiment of the present utility model is for installation on the vehicle body 20. The boom 10 includes a boom body assembly 100 and a hinge seat 200.
[0036] Among them, the boom body assembly 100 includes a plurality of mutually sleeved boom bodies 101. For example, it may include a base boom and a plurality of telescopic booms. The base boom is located on the outermost side, and two adjacent boom bodies 101 are slidably connected. The hinge seat 200 is provided on the outermost base boom. The hinge seat 200 is used for rotatably connecting the vehicle body 20. The rotation axis of the hinge seat 200 can be perpendicular to the width direction and the length direction of the boom body 101. A driving oil cylinder may be provided between the boom body assembly 100 and the vehicle body 20 to control the rotation of the boom 10. The two ends of the boom body 101 in the length direction respectively form a head end 102 and a tail end 103. Specifically, after the boom body assembly 100 is rotatably installed on the vehicle body 20 through the hinge seat 200, the end of the boom body 101 of the boom body assembly 100 away from the vehicle body 20 is the head end 102, and the end of the boom body 101 close to the vehicle body 20 is the tail end 103. The two sides of the boom body 101 in the width direction respectively form a first side 104 and a second side 105. A first notch 106 is formed at the corner of the tail end 103 close to the first side 104. During the rotation of the boom 10, the first notch 106 is located on the side of the tail end 103 close to the vehicle body 20. Along the extension direction of the rotation axis of the hinge seat 200, the first notch 106 can penetrate the tail end 103.
[0037] According to the boom 10 of the first aspect embodiment of the present utility model, since a first notch 106 is provided at the corner of the tail end 103 close to the first side 104, not only is the boom 10 lighter. Moreover, referring to Figure 2 As shown, in the prior art, the first notch 106 is not provided. When the tail end 103 rotates around the rotation axis of the hinge seat 200, the maximum radius of the rotation path of the tail end 103 is R 1 In the present utility model, the first notch 106 is provided. When the tail end 103 rotates around the rotation axis of the hinge seat 200, the maximum radius of the rotation path of the tail end 103 is R 2 R 2 <R 1 In this way, it is not necessary to raise the hinge position of the boom 10 to avoid interference between the boom 10 and the vehicle body 20, making the overall height of the aerial work vehicle lower, more convenient to pass through the height limit area, and better stability during driving and operation.
[0038] Referring to Figure 3 As shown, in some embodiments of the present utility model, the surface of the first notch 106 includes a first plane 107 and a first inclined plane 108 arranged in sequence from the first side 104 to the second side 105. The first plane 107 is perpendicular to the length direction, and the first inclined plane 108 extends obliquely away from the first end 102 from the first side 104 to the second side 105. In this embodiment, the surface of the first notch 106 is arranged in this way, not only the anti-interference effect of the formed first notch 106 is better, but also it is more convenient to process the first notch 106.
[0039] Referring to Figure 3 As shown, in some embodiments of the present utility model, the end face of the tail end 103 forms a second plane 109. The second plane 109 is connected to one end of the first inclined plane 108 away from the first plane 107, and the second plane 109 is perpendicular to the length direction of the boom body 101. Referring to Figure 2 As shown, the initial overlap amount L between two adjacent boom bodies 101 is the minimum distance between the tail end 103 of the inner boom body 101 and the first end 102 of the outer boom body 101, that is, when the two adjacent boom bodies 101 do not relatively slide in the direction away from each other, the distance between the tail end 103 of the inner boom body 101 and the first end 102 of the outer boom body 101. The boom 10 needs to ensure a certain initial overlap amount L. In this embodiment, the end face of the tail end 103 is perpendicular to the length direction of the boom body 101. Arranged in this way, the initial overlap amount L of the boom 10 can be ensured, and the practicability is better.
[0040] Referring to Figure 3As shown, in some embodiments of the present utility model, first reinforcing ribs 110 are provided on one side of the tail end 103 with respect to both the first plane 107 and the second plane 109. The first reinforcing ribs 110 extend in the width direction. Second reinforcing ribs 111 are provided on one side of the tail end 103 with respect to the first inclined surface 108. The second reinforcing ribs 111 extend along the inclined direction of the first inclined surface 108. In this embodiment, by providing the first reinforcing ribs 110 and the second reinforcing ribs 111 at the tail end 103 of the arm body 101, the structural strength and stiffness of the tail end 103 of the arm body 101 can be effectively improved, making the boom 10 not easily damaged and having a longer service life.
[0041] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present utility model, a second notch 112 is formed at the corner of the head end 102 near the second side 105. Along the extension direction of the rotation axis of the hinge seat 200, the second notch 112 can penetrate through the head end 102. In this embodiment, by forming the second notch 112 at the head end 102 of the arm body 101, the boom 10 can be made lighter. In addition, the second notch 112 is located at the corner of the head end 102 of the arm body 101 near the second side 105, that is, the first notch 106 and the second notch 112 are respectively located on both sides in the width direction of the arm body 101. Thus, when two adjacent arm bodies 101 slide to the farthest distance in the direction away from each other, the overlapping effect between the two adjacent arm bodies 101 is better.
[0042] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present utility model, the surface of the second notch 112 includes a third plane 113 and a second inclined surface 114 arranged in sequence from the second side 105 to the first side 104. The third plane 113 is perpendicular to the length direction, and the second inclined surface 114 extends obliquely away from the tail end 103 from the second side 105 to the first side 104. In this embodiment, by setting the surface of the second notch 112 in this way, not only is it more convenient to process the second notch 112, but also the protruding part of the tail end 103 of the inner arm body 101 just fits with the second notch 112 of the head end 102 of the outer arm body 101 among two adjacent arm bodies 101, thereby making the overlapping effect better.
[0043] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present utility model, the end face of the head end 102 forms a fourth plane 115. The fourth plane 115 is connected to one end of the second inclined surface 114 away from the third plane 113, and the fourth plane 115 is perpendicular to the length direction. In this embodiment, the end face of the head end 102 is perpendicular to the length direction of the arm body 101. By setting it in this way, the initial overlapping amount L of the boom 10 can be further ensured, and the practicability is better.
[0044] Reference Figure 3 As shown, in some embodiments of the present utility model, third reinforcing ribs 116 are provided on both sides of the first end 102 with respect to the third plane 113 and the fourth plane 115. The third reinforcing ribs 116 extend in the width direction. Fourth reinforcing ribs 117 are provided on one side of the first end 102 with respect to the second inclined plane 114, and the fourth reinforcing ribs 117 extend along the inclined direction of the second inclined plane 114. In this embodiment, by providing the third reinforcing ribs 116 and the fourth reinforcing ribs 117 at the first end 102 of the arm body 101, the structural strength and stiffness of the first end 102 of the arm body 101 can be effectively improved, making the boom 10 less likely to be damaged and having a longer service life.
[0045] Reference Figure 2 As shown, in some embodiments of the present utility model, a telescopic oil cylinder 118 is provided between two adjacent arm bodies 101, and the telescopic oil cylinder 118 is used to drive two adjacent arm bodies 101 to slide relative to each other. By starting the telescopic oil cylinder 118, the relative sliding of two adjacent arm bodies 101 can be controlled, which is simple and convenient to operate, saving time and effort.
[0046] It should be noted that the width direction mentioned in the present utility model refers to the width direction of the arm body 101, and the length direction mentioned in the present utility model refers to the length direction of the arm body 101.
