[0035] Please see Figure 1-3 The present invention provides a lower crossbeam mounting device for a stacker crane, comprising at least two sets of leg assemblies 1. Each leg assembly 1 includes a mounting crossbeam 11 and support rods 12 disposed at both ends of the mounting crossbeam 11. Roller assemblies 2 are disposed at the bottom of the support rods 12. A flange plate 3 connected to the lower crossbeam 6 is disposed on the mounting crossbeam 11.

[0036] like Figure 1 As shown, Figure 1 This is a schematic diagram illustrating an application scenario of the lower crossbeam installation device for a stacker crane according to this embodiment. In this embodiment, the lower crossbeam 6 of the stacker crane is fixed to the flange plate 3, thereby fixing the lower crossbeam 6 and two sets of support bracket assemblies 1 together. Each set of support bracket assemblies 1 has a support rod 12 at its bottom, and each support rod 12 has a roller assembly 2 at its bottom. Thus, with the cooperation of the four support rods 12 and the roller assembly 2, the lower crossbeam 6, fixedly connected to the two sets of support bracket assemblies 1, essentially forms a crossbeam trolley. By pushing this crossbeam trolley, the lower crossbeam 6 can be moved freely. Therefore, when installing the lower crossbeam 6 on the ground rail, it is only necessary to push the crossbeam trolley to engage the lower crossbeam 6 with the ground rail. After the lower crossbeam 6 is engaged with the ground rail, the two sets of support bracket assemblies 11 can be disassembled sequentially. It should be noted that in this embodiment, a crossbeam flange plate is welded onto the lower crossbeam 6 to mate with the flange plate 3, facilitating the fixing of the lower crossbeam 6 and the mounting crossbeam 11 together.

[0037] In this embodiment, the lower crossbeam 6 is moved by cooperating with the leg assembly 1, which is convenient for installation and improves the installation efficiency of the lower crossbeam 6. At the same time, it avoids a series of problems that would occur if the lower crossbeam 6 were moved by hoisting equipment, making it safer and more reliable to use.

[0038] In a further embodiment, the flange plate 3 is fixedly disposed at the middle position of the mounting beam 11, and the flange plate 3 is provided with a plurality of flange holes 31 on both sides of the mounting beam 11.

[0039] In this embodiment, the flange plate 3 is fixedly installed in the middle position of the mounting beam 11, so that when the lower beam 6 is fixedly connected to the flange plate 3, the lower beam 6 can be fixedly installed in the middle position of the mounting beam 11, making the overall structure more stable when the lower beam 6 is transported.

[0040] In one embodiment, the mounting beam 11 includes a beam rod 111 and beam plates 112 disposed on both sides of the beam rod 111 in the width direction.

[0041] The mounting beam 11 includes a beam rod 111 and a beam plate 112. The beam plate 112 is disposed on both sides of the beam rod 111 in the width direction. The beam plate 112 can increase the strength of the beam rod 111, making the overall structure of the mounting beam 11 more robust.

[0042] In order to further improve the overall strength of tripod assembly 1, such as Figure 2 As shown, in this embodiment, a diagonal brace 13 is fixedly connected between the mounting beam 11 and the support rod 12. The two ends of the diagonal brace 13 are fixedly connected to the mounting beam 11 and the support rod 12 respectively, which can further improve the overall strength of the bracket assembly 1 and make the overall structure more stable.

[0043] In a further embodiment, the crossbeam 111 is provided with a crossbeam through hole, and the flange plate 3 is provided with a flange through hole that mates with the crossbeam through hole. The crossbeam through hole and the flange through hole are fixedly connected by bolts.

[0044] In this embodiment, the crossbeam perforation is used to mate with the flange perforation on the flange plate 3, so that the flange plate 3 and the mounting crossbeam 11 can be fixedly connected together by bolts, which facilitates the disassembly and assembly of the overall structure.

[0045] In one embodiment, such as Figure 3 As shown, the roller assembly 2 includes a roller shaft 21 that is rotatably connected to the bottom of the support rod 12. A roller bracket 22 is fixedly provided at the bottom end of the roller shaft 21, and a roller 23 is provided on the roller bracket 22.

[0046] In this embodiment, the roller assembly 2 is rotatably connected to the bottom of the support rod 12 via the roller shaft 21, so that a universal wheel structure is formed at the bottom of the support rod 12. Thus, when the bracket assembly 1 is fixedly installed with the lower crossbeam 6, the lower crossbeam 6 can be pushed to move in any direction, making it easier to install the lower crossbeam 6.

[0047] In another embodiment, such as Figure 4 and Figure 5 As shown, the support rod 12 includes a fixed sleeve rod 121 and a telescopic slide rod 122. The telescopic slide rod 122 slides along the inner wall of the fixed sleeve rod 121. The fixed sleeve rod 121 is fixedly connected to the mounting beam 11. An operating rod 4 is rotatably arranged inside the fixed sleeve rod 121. A threaded hole 1221 is fixedly arranged on the telescopic slide rod 122, and the operating rod 4 is threadedly engaged with the threaded hole 1221.

[0048] In this embodiment, to facilitate the installation between the lower crossbeam 6 and the ground rail, the support rod 12 is configured as a telescopic structure. To facilitate the extension and retraction of the support rod 12, in this embodiment, the support rod 12 is configured as a fixed sleeve rod 121 and a telescopic slide rod 122. The fixed sleeve rod 121 is hollow, and the top of the fixed sleeve rod 121 is welded to the crossbeam rod 111. The telescopic slide rod 122 slides from the fixed sleeve rod 121 at the lower end of the fixed sleeve rod 121.

[0049] Specifically, a top hole 1211 is provided through the top of the fixed sleeve rod 121. The operating rod 4 passes through the top hole 1211 into the fixed sleeve rod 121. Two limiting rings 41 are fixedly provided around the operating rod 4, clamping the two sides of the top of the fixed sleeve rod 121, allowing the operating rod 4 to rotate within the top hole 1211, but preventing it from moving axially. A threaded hole 1221 is provided at the top of the telescopic slide rod 122, and the operating rod 4 is threaded into the threaded hole 1221. Thus, by rotating the operating rod 4, the operating rod 4 can drive the telescopic slide rod 122 to move up and down along the fixed sleeve rod 121, allowing the telescopic slide rod 122 to slide inside the fixed sleeve rod 121, thereby realizing the function of adjusting the overall length of the support rod 12.

[0050] Therefore, before use, the operating lever 4 can be rotated to adjust the support rod 12 to a suitable length, so that after the lower crossbeam 6 is fixedly connected to the mounting crossbeam 11, the lower crossbeam 6 can be directly fitted to the ground rail. Alternatively, the lower crossbeam 6 can be fixed to the mounting crossbeam 11 first, and then the operating lever 4 can be rotated to adjust the support rod 12 to a suitable height, so that the lower crossbeam 6 can be smoothly installed on the ground rail.

[0051] To facilitate the rotation of the operating lever 4, an operating handwheel 42 is provided at the end of the operating lever 4 away from the fixed sleeve 121.

[0052] The handwheel 42 is designed to make it easier to rotate the lever 4 and adjust the height of the support rod 12.

[0053] In a further embodiment, a fixing plate 1222 is fixedly installed inside the telescopic slide rod 122. A fixing hole is provided through the fixing plate 1222. A nut 1223 is welded to the fixing plate 1222 at the position corresponding to the fixing hole. The fixing hole and the nut 1223 cooperate to form a threaded hole 1221.

[0054] The engagement of the fixing hole and the nut 1223 increases the length of the threaded hole 1221, thereby increasing the stability of the engagement between the operating rod 4 and the threaded hole 1221 and extending the service life of the engagement between the operating rod 4 and the threaded hole 1221.

[0055] In another embodiment, such as Figure 6As shown, the two sets of tripod assemblies 1 are fixedly connected by several connecting rods 5.

[0056] In this embodiment, two leg assemblies 1 can be fixedly connected by connecting rods 5 to form a mobile trolley. Specifically, the two leg assemblies 1 are fixedly connected by two connecting rods 5. A mounting groove 1111 is provided on the top of the mounting beam 11, and connecting rod grooves 51 that mate with the mounting grooves 1111 are provided at both ends of the connecting rods 5. After the connecting rod grooves 51 and the mounting grooves 1111 are engaged, they are fixedly connected by bolts. This forms a mobile trolley, which facilitates the movement of other devices.

[0057] This utility model mainly includes a support frame assembly 1, which consists of a mounting beam 11 and support rods 12 at both ends. Roller assemblies 2 are mounted on the bottom of the support rods 12, and flange plates 3 are provided on the mounting beam 11 for connecting to the lower beam 6. The lower beam 6 is fixed to the two sets of support frame assemblies 1 via the flange plates 3, forming a "beam trolley" with rollers. The lower beam 6 can be easily moved to engage with the ground rail. After installation, the support frame assembly 1 can be disassembled. This device is easy to install, highly efficient, avoids hoisting risks, and is safe and reliable. Furthermore, the support rods 12 can be designed as an adjustable structure including a fixed sleeve rod 121 and a telescopic slide rod 122. The height can be adjusted by rotating the operating rod 4, further improving installation adaptability. The two sets of support frame assemblies 1 can also be connected to form a universal mobile trolley via connecting rods 5, expanding its applications.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
