Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, and more specifically, to a slewing frame for gantry cranes. Background Technology

[0002] In the field of gantry cranes, a slewing frame is connected to the gantry crane for transition, and then different lifting devices are connected to lift the corresponding products.

[0003] The gantry crane is generally connected to the slewing frame by steel wire rope. The traditional structure is a fixed structure, which cannot be compatible with both pulley and spreader beam connection methods. The cable routing is messy and prone to entanglement and interference, resulting in low space utilization. In addition, a separate electrical control cabinet is required, which increases the manufacturing cost.

[0004] With the continuous development of the economy, there are higher requirements for the adaptability, cost and maintenance of the slewing frame connected to the gantry crane. It is required that the connection method of the slewing frame connected to the gantry crane be universal and adaptable to different connection methods. At the same time, the design of electrical control and other components should be intensively modified, the wiring should be simpler, and an integrated device should be formed. Ultimately, the slewing frame should have better mechanical protection performance and versatility, and be more durable. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a slewing frame for gantry cranes that is compatible with both spreader beam and pulley box connection methods, optimizes the electrical structure to ensure the safety of electrical facilities, and extends the service life of electrical components.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0027] like Figures 1-6 As shown, a slewing frame for a gantry crane includes a slewing frame body 1, a connecting pin 2, an integrated housing 3, and a cover plate 4.

[0028] In this embodiment, the upper two ends of the main body 1 of the rotating frame rise upwards, forming two triangular shoulder structures, each equipped with a connecting pin 2. The axial direction of the connecting pin 2 is the same as the length direction of the main body 1 of the rotating frame, and is used to connect the pulley box 7 and the spreader beam 8, such as... Figure 5 The diagram shows the assembly of the main body 1 of the slewing frame with the pulley box via the connecting pin 2. Figure 6 The diagram shown is a schematic of the assembly of the main body 1 of the slewing frame with the spreader beam 8 via the connecting pin 2.

[0029] The main body 1 of the rotating frame is provided with an integrated box 3, which is equipped with an openable and closable cover 4. The space inside the integrated box 3 is used for installing electrical components and wiring.

[0030] Specifically, in this embodiment, the front, rear, and upper sides of the rotary frame body 1 are provided with sealing plates, which, together with the shoulders and bottom plates at both ends of the rotary frame body 1, form the integrated box 3, as shown below. Figure 4 As shown, the integrated housing 3 is located in the space below the shoulders at both ends of the entire rotating frame.

[0031] Since the main body 1 of the rotary frame is made of metal, there is a certain risk of electrical conductivity. In order to ensure the safety of the installation of electrical components, a special base 5 is provided on the bottom plate of the main body 1 of the rotary frame. The special base 5 is equipped with an insulation structure, such as an insulation layer, an insulating varnish, or the special base 5 is designed to be made of insulating material. The special base 5 is used to install electrical components.

[0032] Meanwhile, to ensure the orderly routing of cables, a cable conduit 6 is installed in the integrated enclosure 3, which is dedicated to cable routing. The cable conduit 6 is made of metal steel pipe or rubber pipe.

[0033] To facilitate wiring and maintenance, a cover plate 4 is provided. This cover plate is located at one end of the main body of the rotary frame, typically on one side of the integrated housing 3 structure. Figure 3 As shown, cover plate 4 is located at the left end.

[0034] In other embodiments, the integrated housing may also be designed at the right end or the middle part of the entire rotary frame, and the cover plate may also be set on the sealing plate on the front or rear side of the rotary frame body accordingly.

[0035] To ensure the impact resistance of the integrated enclosure 3, the side panels and covers of the integrated enclosure are all made of metal plates. Of course, in some designs with requirements for the power environment, the side panels and covers can also be designed as plastic plates.

[0036] Overall, the slewing frame body 1 can be connected to the main machine in different ways through the connecting pin 2. It can be connected to the gantry crane wire rope shackle through the spreader beam, or it can be connected to the gantry crane wire rope pulley through the pulley box, which improves the adaptability of the slewing frame and makes it easy to replace.

[0037] The main design of the slewing frame includes a pre-installed integrated box 3 for installing electrical components. The box is covered by a cover plate 4, and the electrical components are installed on a dedicated base 5 inside the integrated box. The box can be used as an electrical box, eliminating the need for an external electrical box, reducing the manufacturing cost of purchasing electrical boxes, and providing mechanical protection for the electrical components, thus reducing the risk of collisions with the electrical components during use.

[0038] Inside the main body of the slewing frame, there is a cable conduit 6. Electrical wiring can be routed inside the structure through the cable conduit 6, which is a standardized layout, improves space utilization, facilitates maintenance, and avoids long-term exposure of cables to the external space, providing a kind of mechanical protection for the cables and extending their service life.

[0039] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
