[0004] To achieve the above objectives, this utility model provides a boom support structure, including a support beam plate, a reinforcing support and a boom support, wherein the reinforcing support is generally in the shape of an inverted trapezoid and is fixedly mounted on the support beam plate.

[0005] The number of boom supports is two, and the two boom supports are symmetrically arranged on the top of the reinforcing support. The boom support is provided with a boom assembly station.

[0006] In one embodiment, the reinforcing support includes a cover plate and a web plate, a first transverse stiffener, a second transverse stiffener, a first longitudinal stiffener, and a second longitudinal stiffener fixedly disposed at the bottom of the cover plate.

[0007] The number of webs is two and they are symmetrical to each other. The bottom end of the webs is inclined inward. The two ends of the first transverse stiffener and the second transverse stiffener are connected to the two webs. The first longitudinal stiffener is connected to the second transverse stiffener, and the second longitudinal stiffener is connected to the first transverse stiffener and the second transverse stiffener.

[0008] The two boom supports are symmetrically arranged on the top of the cover plate, and the web plate, the first transverse stiffener, the second transverse stiffener are connected to the support beam plate.

[0009] In one embodiment, there are multiple first longitudinal stiffeners and multiple corresponding second longitudinal stiffeners, and the first longitudinal stiffeners and the corresponding second longitudinal stiffeners are located in the same plane.

[0010] In one embodiment, both the first transverse stiffener and the second transverse stiffener have notches at their bottom ends, and bottom stiffeners are fixedly provided at the notches at the bottom ends of the first transverse stiffener and the second transverse stiffener.

[0011] In one embodiment, the boom support includes a back plate, a vertical plate, a first side plate, a second side plate, a first ear plate, and a second ear plate;

[0012] The first ear plate, the first side plate, and the second side plate are connected to the back plate, and the first ear plate is connected to the top of the first side plate and the top of the second side plate.

[0013] The upright plate and the second ear plate are both connected between the first side plate and the second side plate. The bottom of the upright plate is connected to the first ear plate, and the second ear plate is connected to the outer wall of the upright plate. The first ear plate and the second ear plate are provided with coaxial pin holes.

[0041] Example 1

[0042] like Figure 1 The diagram shows a boom support structure disclosed in this embodiment, which mainly includes a support beam plate 1, a reinforcing support 2, and a boom support 3. The reinforcing support 2 has an overall inverted trapezoidal structure and is fixedly mounted on the support beam plate 1. There are two boom supports 3, symmetrically arranged on the top of the reinforcing support 2. Each boom support 3 has a boom assembly station for supporting the boom 4 to complete operations. By fixing the reinforcing support 2 to the support beam plate 1, the support beam plate 1 can be directly welded to the vehicle frame beam during application. This eliminates the need for additional complex crossbeams and other force-transmitting components, reducing redundant structural parts and effectively lowering the weight of the boom support structure and the overall vehicle, thus reducing costs.

[0043] refer to Figures 2 to 5 The reinforced support 2 includes a cover plate 201 and web plates 202, a first transverse stiffener 203, a second transverse stiffener 204, a first longitudinal stiffener 205, and a second longitudinal stiffener 206, which are fixedly welded to the bottom of the cover plate 201. There are two web plates 202, which are symmetrical to each other, and the bottom ends of the web plates 202 are inclined inwards, thus making the reinforced support 2 have an overall inverted trapezoidal structure. The two ends of the first transverse stiffener 203 and the second transverse stiffener 204 are welded and fixed to the two web plates 202. The first transverse stiffener 203 is located near the rear end of the overall boom support structure, and the second transverse stiffener 204 is located near the front end of the overall boom support structure, with the bottom end of the second transverse stiffener 204 inclined towards the front end of the overall boom support structure. The first longitudinal stiffener 205 is welded and fixed to the second transverse stiffener 204, meaning the first longitudinal stiffener 205 has a triangular shape. The second longitudinal stiffener 206 is connected to the first transverse stiffener 203 and the second transverse stiffener 204, meaning the second longitudinal stiffener 206 is located inside the reinforcing support 2 and has a quadrilateral shape. Two boom supports 3 are symmetrically welded to the top of the cover plate 201, respectively located above the two web plates 202. The bottom ends of the web plates 202, the first transverse stiffener 203, and the second transverse stiffener 204 are welded and fixed to the supporting beam plate 1. The first transverse stiffener 203 has plug weld holes to enhance the connection strength.

[0044] In a preferred embodiment, there are multiple first longitudinal stiffeners 205 and second longitudinal stiffeners 206, and they correspond one-to-one. At the same time, the first longitudinal stiffeners 205 and the corresponding second longitudinal stiffeners 206 are located in the same plane, thereby improving the structural stability of the reinforced support 2.

[0045] refer to Figure 6 The boom support 3 includes a back plate 301, a vertical plate 302, a first side plate 303, a second side plate 304, a first ear plate 305, and a second ear plate 306. The back plate 301 is located near the rear end of the overall boom support structure, and the vertical plate 302 is located near the front end of the overall boom support structure. The first ear plate 305, the first side plate 303, and the second side plate 304 are all welded to the back plate 301, and the first ear plate 305 is welded to the top of the first side plate 303 and the top of the second side plate 304, respectively. The vertical plate 302 and the second ear plate 306 are welded between the first side plate 303 and the second side plate 304. At the same time, the top of the vertical plate 302 is welded to the bottom of the first ear plate 305, and the second ear plate 306 is welded to the outer wall of the vertical plate 302. The bottom ends of the back plate 301, the vertical plate 302, the first side plate 303, and the second side plate 304 are welded to the top of the cover plate 201. The first ear plate 305 and the second ear plate 306 are provided with coaxial pin holes for mounting the boom 4 with a pin.

[0046] More specifically, a hinge seat 307 is provided on the outer wall of the first side plate 303 for mounting the side swing cylinder 5 of the boom 4, so as to meet the necessary left and right swing requirements of the boom 4 during operation. Figure 7 Preferably, a limiting block 308 is provided on the outer wall of the upright plate 302 at a position corresponding to the pin hole and the second side plate 304, to limit the inward swing angle of the boom 4, so as to ensure that the boom 4 operates within a safe range.

[0047] In a preferred embodiment, the welding edge of the back plate 301 on the cover plate 201 and the welding edge of the first transverse stiffener 203 on the cover plate 201 are located in the same vertical plane; the welding edge of the upright plate 302 on the cover plate 201 and the welding edge of the second transverse stiffener 204 on the cover plate 201 are located in the same vertical plane; the welding edge of the first side plate 303 on the cover plate 201 and the welding edge of the web plate 202 on the cover plate 201 are located in the same vertical plane; and the welding edge of the second side plate 304 on the cover plate 201 and the welding edges of the first longitudinal stiffener 205 and / or the second longitudinal stiffener 206 on the cover plate 201 are located in the same vertical plane. Through the precise alignment and positioning design of the structural components on the boom support 3 and the reinforcing support 2, the support effect of the boom support structure on the boom can be significantly enhanced. Simultaneously, the support reaction force can be directly and efficiently transmitted back to the support beam plate 1 along the stiffeners, upright plates 302, and other components, and then transmitted to the frame beam, resulting in clear force flow and high reliability.

[0048] In the specific forming process of the boom support structure in this embodiment, a separate welding and overall integration strategy can be adopted. That is, after the two boom supports 3 and the reinforcing support 2 are welded separately, the two boom supports 3 are then precisely welded to the reinforcing support 2, thereby ensuring that the two boom supports 3 and the reinforcing support 2 form a highly unified rigid whole, which significantly improves the rigidity and stability of the entire boom support structure.

[0049] Example 2

[0050] like Figures 8 to 10 The diagram shows a boom support structure disclosed in this embodiment. Its implementation is basically the same as that of Embodiment 1, except that: in this embodiment, both the bottom ends of the first transverse stiffener 203 and the second transverse stiffener 204 are provided with notches, and bottom stiffeners 207 are fixedly provided at the bottom notches of the first transverse stiffener 203 and the second transverse stiffener 204. Furthermore, the support beam 1 in this embodiment is divided into two parts, respectively supporting two web plates 202 and the two ends of the first transverse stiffener 203 and the second transverse stiffener 204.

[0051] In this embodiment, the boom support structure provides notches at the bottom ends of the first transverse stiffener 203 and the second transverse stiffener 204, thereby freeing up the bottom space of the reinforcing support 2 and making the trolley chassis easier to lay out.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
