Abstract
Description
Technical Field
[0001] This invention relates to the field of cranes, and more particularly to a universal structure for a winch mounting turntable and a crane. Background Technology
[0002] The turntable serves as a platform structure for mounting components such as winches, power systems, hydraulic systems, and electrical systems on crawler cranes. For products of the same tonnage, the structure varies due to differences in the installation and connection points of different winch systems and other components. This results in a wide variety of materials being handled, making data maintenance and manufacturing processes time-consuming and labor-intensive throughout the entire chain. Furthermore, due to urgent market and customer needs, temporary replacements or modifications are difficult to implement. The existing structure cannot quickly meet the diverse needs of different customers for different configurations of winch systems and other components for the same tonnage product, and cannot rapidly produce products with different configurations.
[0003] In the existing technology, because different types of hoisting systems have different hoisting support structures, the structure of the hoist installed on the turntable is also different in order to match different hoisting support structures. That is, the hoist and the turntable are matched one by one, which makes the turntable structure very diverse.
[0004] like Figure 1 , Figure 2 As shown, different lifting winch systems for products of the same tonnage use different installation methods, including bolted connections or pin connections. Figure 1 It is a bolted connection type, with a bolted connection plate 2a fixed on the turntable structure 1a; Figure 2 It is a pin-connected type, with a pin-connecting plate 2b fixed on the turntable structure 1a. Correspondingly, there are two types of turntable structures, that is, two different types of mounting seats are welded on the same turntable main structure, thus forming two parallel turntable materials, two products, two hoisting systems, two turntable structures, and two completely independent sets of products.
[0005] Due to the ever-changing nature of market demand, situations often arise where inventory vehicles are no longer needed. For example, the inventory might consist of commonly used pin-connected winch system vehicles, while the user urgently needs bolt-connected winch system vehicles. Starting production from scratch for one unit would take approximately three months, and the existing inventory would remain unsold, increasing both time and inventory costs. To utilize the inventory, it's necessary to temporarily cut off the pin-connected winch mounting plates and weld on bolt-connected winch mounting plates. This modification requires on-site cutting and welding, which is time-consuming and labor-intensive. Summary of the Invention
[0006] Purpose of the invention: To address the above-mentioned shortcomings, this invention provides a universal structure for a winch installation turntable and a crane that can quickly meet market demands.

The hoisting mechanism is connected to the turntable structure via a first mounting connection portion of the first mounting lug or a second mounting connection portion of the second mounting lug. When the hoisting mechanism is connected to the turntable structure via the first mounting connection portion of the first mounting lug, the second mounting lug is not mounted on the first mounting lug; when the hoisting mechanism is connected to the turntable structure via the second mounting connection portion of the second mounting lug, the second mounting lug is mounted on the first mounting lug.
[0014] Furthermore, two symmetrically arranged first mounting ears are welded onto the turntable structure.

[0022] like Figure 3 As shown, this embodiment of a hoist mounting turntable universal structure includes a first mounting ear plate 1 and / or a second mounting ear plate 2. The first mounting ear plate 1 is provided with a first mounting method connection part 11 and a first universal connection part 12 for mounting the second mounting ear plate 2. The second mounting ear plate 2 is provided with a second mounting method connection part 21 and a second universal connection part 22 for mounting on the first mounting ear plate 1. The first universal connection part 12 and the second universal connection part 22 are matched and connected. The second mounting ear plate 2 is mounted on the first mounting ear plate 1 by connecting the first universal connection part 12 through the second universal connection part 22. The first mounting method of the first mounting method connection part 11 of the first mounting ear plate 1 is switched to the second mounting method of the second mounting method connection part 21 of the second mounting ear plate 2.
[0023] In this embodiment, the first mounting ear plate 1 is a bolt-connected ear plate, and the second mounting ear plate 2 is a pin-connected ear plate. The second mounting ear plate 2 can also be a snap-fit type or other connection method, which can be set according to the actual product requirements.
[0024] like Figure 4 and Figure 5 The first mounting method connection part 11 and the first universal connection part 12 provided on the first mounting ear plate 1 are bolt holes of different or the same size provided on the ear plate. In this embodiment, the first mounting method connection part 11 has two first bolt holes and the first universal connection part 12 has four second bolt holes. The first bolt holes are used to bolt to the hoisting system with bolt connection, and the second bolt holes are used to connect the ear plate with the pin shaft.
[0025] The second mounting method connection part 21 on the second mounting ear plate 2 is a pin bracket with pin holes. There are two symmetrical pin brackets on one ear plate. The pin holes of the hoisting system are located between the two pin brackets and are connected by pins. The second general connection part 22 on the second mounting ear plate 2 for mounting on the first mounting ear plate 1 is a mounting base with four third bolt holes. The third bolt holes on the mounting base correspond to the positions and sizes of the four second bolt holes on the bolt connection ear plate.

The pin connection ear plate is installed on the bolt connection ear plate, and the bolt connection is switched to the pin connection.
[0026] The modular, compatible installation structure accommodates various winch systems and installation locations. Based on sales volume, a pin-connected winch system is selected as the standard configuration, with the pin-connecting lugs being modular. In this case, the pin-connected winch system is installed. For vehicles requiring an emergency connection, a bolt-connected winch system is used; simply remove the connecting bolts, gaskets, and pin-connecting lugs from the turntable structure to convert it to a bolt-connected system. Figure 4 As shown in the diagram, the bolted connection allows for the simple and quick installation of the bolt-connected winch system. Specifically, the bolt-connected lugs include threaded holes for the bolt-connected winch system and threaded holes for the pin connection lugs. Figure 5 As shown. This universal turntable structure can accommodate both bolt-connected and pin-connected winch systems, allowing for quick switching between two different vehicle configurations to meet specific market demands.
