Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, and more specifically, to a rotating lifting device for a crane. Background Technology

[0002] In railway container yards where trains are the primary mode of freight transport, to prevent theft, trains typically place two 20-foot containers facing each other on a single train. Trains on the railway line come from different directions, and trains going either up or down can enter the station, resulting in the containers facing different directions upon arrival at the loading / unloading station. When cranes unload containers, some containers need to be rotated 180° to ensure the containers face the same direction on the truck for easier loading and unloading.

[0003] Currently, cranes typically use swivel spreaders to rotate containers. However, traditional swivel spreaders usually lack protective devices. If these spreaders are not regularly maintained, the spreader may fall from a height if the bolts connecting the upper and lower spreaders rust or loosen, posing a safety hazard.

[0004] Therefore, how to provide a rotating lifting device that can prevent the lifting frame or lifting device from falling and avoid safety accidents when the connection and locking device fails has become a technical problem that urgently needs to be solved by those skilled in the art.

[0045] The technical solution of this utility model will be specifically described below with reference to the embodiments:

[0046] Specifically, in an embodiment of this utility model, the hanger anti-fall mechanism 7 includes: a support horizontal plate 701 disposed on the top of the first flange 3; a fastening assembly 702 disposed on the support horizontal plate 701 and connecting the support horizontal plate 701 and the first flange 3; a support vertical plate 703 vertically disposed on the side wall of the support horizontal plate 701; a support flange 704 disposed at the lower end of the support vertical plate 703 and parallel to the support horizontal plate 701; one end of the support flange 704 is connected to the support vertical plate 703, and the other end is located below the second flange 5; and a reinforcing rib plate 705 connected to the support vertical plate 703 and the support flange 704.

[0047] like Figure 2 , 3As shown, in this embodiment of the present invention, the hanger anti-fall mechanism 7 is used to prevent the second hanger 4 from falling when the first hanger 1 and the second hanger 4 separate. In this embodiment, the main structure of the hanger anti-fall mechanism 7 consists of the supporting horizontal plate 701, the fastening assembly 702, the supporting vertical plate 703, the supporting flange 704, and the reinforcing rib plate 705. The supporting horizontal plate 701 is installed on the top of the first flange 3 and is detachably connected to the first flange 3 through the fastening assembly 702. A fastening assembly is provided on the outer wall of the supporting horizontal plate 701. The support vertical plate 703 is described above, and the support flange 704 is installed below the second flange 5. One end of the flange 704 is connected to the support vertical plate 703, and the other end is used to support the second flange 5 when the first hanger 1 and the second hanger 4 separate, that is, to lift the second hanger 4. The support vertical plate 703 and the support flange 704 together form an L-shaped assembly. When the device for connecting and locking the first hanger 1 and the second hanger 4 fails, the first hanger 1 and the second hanger 4 may separate. The L-shaped assembly can be used to firmly hook the second hanger 4 to prevent it from falling.

[0048] Specifically, in the embodiments of this utility model, the fastening component 702 is a bolt fastener, and the hanger anti-fall mechanism 7 is detachably connected to the first flange 3.

[0049] Specifically, in an embodiment of this utility model, the slewing mechanism 6 includes: a slewing drive assembly 601 disposed on the first hanger 1; a slewing bearing 602 connected to the slewing drive assembly 601; the outer ring of the slewing bearing 602 is connected to the first flange 3, and the inner ring of the slewing bearing 602 is connected to the second flange 5.

[0050] like Figure 4 As shown, in this embodiment of the invention, the slewing mechanism 6 drives the second lifting frame 4 to rotate around a fixed axis, thereby allowing the crane to reverse the direction of the container when lifting it. In this embodiment, the main structure of the slewing mechanism 6 consists of two parts: the slewing drive assembly 601 and the slewing support 602. The slewing drive assembly 601 is fixedly mounted on the first lifting frame 1, and it drives the slewing support 602 to rotate, thereby causing the second lifting frame 4 to rotate around the center of rotation.

[0051] Specifically, in an embodiment of this utility model, the rotating hoist frame further includes an oil receiving tray 11 disposed at the circumferential edge of the slewing bearing 602.

[0052] In this embodiment of the utility model, the slewing bearing 602 generally requires lubrication with lubricating oil during operation; however, the lubricating oil easily overflows and drips onto the lifting device during operation. To solve this problem, such as... Figure 4 As shown, in this embodiment, the rotating lifting device is also equipped with the oil receiving tray 11. The oil receiving tray 11 is installed at the circumferential edge of the slewing bearing 602. When the slewing mechanism 6 is working, it can catch the lubricating oil on the slewing bearing 602, so that it does not fall onto the lifting device and affect the environment.

[0053] Specifically, in an embodiment of this utility model, the pivot mechanism 8 includes: movable pivot pins 801 disposed at the four bottom corners of the second hanger 4 and connected to the lifting device; and pivot pin opening and closing assembly 802 disposed on the second hanger 4 and connected to the movable pivot pins 801.

[0054] like Figure 5 As shown in the embodiment of this utility model, the pivot mechanism 8 is composed of the movable pivot 801 and the pivot opening and closing assembly 802; wherein, the movable pivot 801 is installed at the four corners of the bottom of the second hanger 4 and is connected to the lifting device, while the pivot opening and closing assembly 802 is installed on the second hanger 4 and is connected to the movable pivot 801, and can control the opening and closing of the movable pivot 801.

[0055] Specifically, in an embodiment of this utility model, the anti-fall mechanism 9 of the lifting device includes: a mounting base 901 disposed at the bottom of the second lifting frame 4; an anti-fall connector for the lifting device with one end connected to the mounting base 901 and the other end connected to the anti-fall connector of the lifting device.

[0056] Specifically, in embodiments of this utility model, the fall arrestor includes: a fall arrestor chain or a fall arrestor shackle.

[0057] like Figure 5 As shown, the anti-fall mechanism 9 of the lifting device is installed at the bottom of the second lifting frame 4. When the pivot mechanism 8 fails, the anti-fall mechanism 9 can catch the lifting device and prevent it from falling to the ground and causing a safety accident. In this embodiment of the utility model, the anti-fall mechanism 9 of the lifting device consists of the mounting base 901 and the anti-fall connector. The mounting base 901 is located at the bottom of the second lifting frame 4, and the anti-fall connector is connected to the mounting base 901 at one end and to the lifting device at the other end. When the lifting device is detached from the second lifting frame 4, the anti-fall connector can lift the lifting device to prevent it from falling downwards.

[0058] Specifically, in an embodiment of this utility model, the rotating hoist frame further includes a cable storage basket 10 disposed on the first hoist 1.

[0059] Specifically, in the embodiments of this utility model, multiple anti-fall mechanisms 7 are provided, and the multiple anti-fall mechanisms 7 are evenly spaced on the first flange 3.

[0060] As described above, the rotating lifting frame provided by this utility model aims to solve the problem that traditional rotating lifting frames may experience the fall of the lifting frame or lifting device during operation, leading to safety accidents. To address the above problem, this utility model discloses a rotating lifting frame equipped with the aforementioned lifting frame anti-fall mechanism 7 and the lifting device anti-fall mechanism 9. When the connecting device on the frame fails, the lifting frame anti-fall mechanism 7 and the lifting device anti-fall mechanism 9 can respectively catch the corresponding lifting frame or lifting device, preventing it from falling and eliminating safety hazards. Specifically, the main structure of the rotating lifting device disclosed in this utility model consists of a first lifting frame 1, a pulley mechanism 2, a first flange 3, a second lifting frame 4, a second flange 5, a slewing mechanism 6, a lifting frame anti-fall mechanism 7, a pivot mechanism 8, and the lifting device anti-fall mechanism 9. The pulley mechanism 2 is installed on the top of the first lifting frame 1 and connected to the crane trolley to drive the entire device to move. The first flange 3 is installed at the bottom of the first lifting frame 1, and the second flange 5 is installed on the top of the second lifting frame 4. The slewing mechanism 6 is arranged between the first lifting frame 1 and the second lifting frame 4, connecting the first flange 3 and the second flange 5. It provides rotational driving force to drive the second lifting frame 4 to rotate. It consists of a slewing drive assembly 601 and a slewing bearing 602. The slewing drive assembly 601 is fixed on the first lifting frame 1 and drives the slewing bearing 602 to rotate, causing the second lifting frame 4 to rotate around the slewing center. The heart rotates, and several anti-fall mechanisms 7 are installed between the first hanger 1 and the second hanger 4. The upper end of the anti-fall mechanism 7 is connected to the first flange 3 by connecting bolts, and the lower end is provided with the support flange 704. The support flange 704 is located below the second flange 5. When the locking device connecting the first hanger 1 and the second hanger 4 fails, that is, when the first hanger 1 and the second hanger 4 separate, the anti-fall mechanism 7 can firmly hook the second flange 5 and prevent it from falling. Secondly, the pivot pin mechanism 8 is installed at the four corners of the bottom of the second hanger 4. It is used to connect and lock the lifting device. When the pivot pin mechanism 8 fails, in order to prevent the lifting device from falling, the device anti-fall mechanism 9 is provided at the bottom of the second hanger 4. The two ends of the device anti-fall mechanism 9 are respectively connected to the second hanger 4 and the lifting device, so that when the pivot pin mechanism 8 fails, the device anti-fall mechanism 9 can limit the lifting device from falling and avoid safety accidents. Therefore, it can be seen that the technical solution provided by this utility model, compared with the prior art, can ensure that the hanger or lifting device does not fall when the connection and locking device of the hanger or lifting device fails, thus avoiding safety accidents.
