Abstract
Description
Technical Field
[0001] This utility model relates to the field of cranes, and in particular to a partitioned turntable enclosure structure and a crawler crane. Background Technology
[0002] Due to differences in tonnage, crawler cranes have different turntable structures. The main structure in the middle plus the side enclosures is a common structure for small-tonnage models from various manufacturers. With rapid product updates and iterations and high manufacturing quality requirements, each production stage affects the product's manufacturing cost, market promotion, and reputation.
[0003] As an exposed component, the flatness of the turntable enclosure structure has a significant impact on the overall appearance quality of the machine. Therefore, ensuring the appearance quality of the turntable enclosure structure is of paramount importance.
[0004] The existing turntable enclosure structure consists of a large frame structure composed of a front three-way bending component and a vertical long bending plate. The frame structure is internally welded with stiffening plates. Due to the weight and cost limitations of the main unit, the thickness of the bending plates used in the turntable enclosure structure is generally 5mm. The welding of the internal stiffening plates causes large local deformation of the large frame structure, resulting in obvious weld marks after painting, which affects the appearance quality. To solve this problem, putty needs to be applied before painting. However, applying putty makes the topcoat prone to peeling off, affecting the quality of the subsequent paint film.
[0005] Therefore, it is necessary to develop a new type of turntable enclosure structure to avoid the above problems. Utility Model Content
[0006] Purpose of the utility model: To address the shortcomings and defects of the existing technology, this utility model provides a partitioned turntable enclosure structure and a crawler crane, avoiding the problems of obvious weld marks and poor appearance quality caused by the weld seams of the internal welded stiffeners, and eliminating the need for puttying before painting; thus improving appearance quality and simplifying operation.
[0007] Technical solution: The present invention provides a partitioned turntable enclosure structure, characterized in that it includes a horizontal curved plate, a vertical curved plate and a partition, wherein the two ends of the horizontal curved plate are located in the upper and lower planes of the vertical curved plate; and the partition is located in the upper and lower planes of the vertical curved plate.
[0008] The partition is connected to the mounting stiffeners inside the turntable enclosure.
[0009] The two ends of the horizontal bending plate are fixedly connected to the vertical bending plate.
[0010] The partition plate is fixedly connected to the vertical curved plate.
[0011] The partition plate is fixedly connected to the mounting stiffener plate.
[0012] A crawler crane, characterized in that it uses the partitioned turntable enclosure structure of this utility model.
[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention avoids the problem of obvious weld marks and poor appearance quality caused by the weld seam of the internal welded stiffener plate, and no putty is required before painting; it improves the appearance quality and simplifies the operation. Attached Figure Description
[0014] Figure 1 This is a structural diagram of a turntable enclosure structure in the prior art.
[0015] Figure 2 This is a schematic diagram of the structure of this utility model;
[0016] In the diagram, 1 is a horizontal curved plate; 2 is a vertical curved plate; and 3 is a partition. Detailed Implementation
[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] This utility model relates to a crawler crane: a mobile crane using a crawler chassis. Turntable: a platform structure on the crane used to mount components such as the hoisting mechanism, luffing mechanism, A-frame, and engine system.
[0019] This utility model discloses a partitioned turntable enclosure structure, comprising a horizontal curved plate 1, a vertical curved plate 2, and a partition plate 3. The two ends of the horizontal curved plate 1 lie within the upper and lower planes of the vertical curved plate 2; the partition plate 3 also lies within the upper and lower planes of the vertical curved plate 2. The partition plate 3 is connected to the mounting stiffeners inside the turntable enclosure panel. The two ends of the horizontal curved plate 1 are fixedly connected to the vertical curved plate 2. The partition plate 3 is fixedly connected to the vertical curved plate 2. The partition plate 3 is fixedly connected to the mounting stiffeners.
[0020] This utility model proposes a partition-type enclosure structure. The large frame structure consists of horizontal curved plates, vertical curved plates, and partitions. The internal stiffeners of the enclosure are welded to the partitions, and the partitions are welded to the upper and lower inner planes of the vertical curved plates. The exposed exterior facade has no weld seams or weld marks, and the appearance is smooth and flat, ensuring aesthetic appeal.
[0021] like Figure 2 As shown, the perimeter panel structure frame consists of horizontal curved plates, vertical curved plates, and partitions. To avoid the impact of welding deformation on the exterior facade, the connection between the internal installation stiffeners and the inner facade of the vertical curved plates is transferred to the partitions and the upper and lower surfaces of the partitions and vertical curved plates. Specifically, the internal installation stiffeners are welded to the partitions, and the partitions are welded to the upper and lower inner surfaces of the vertical curved plates. By adding partitions and transferring the weld seams, the exterior facade of the vertical curved plates is free of weld seams and weld marks.
[0022] This invention avoids the problems of obvious weld marks and poor appearance quality caused by the weld seams of the internal welded stiffeners, and eliminates the need for puttying before painting; thus improving appearance quality and simplifying operation.
