Description

Technical Field

[0001] The utility model relates to the technical field of crane floodlight equipment, in particular to a mounting frame for a crane floodlight. Background Art

[0002] With the continuous development of social economy, crane equipment has been used in many industries such as construction, manufacturing, and transportation. When using cranes for night operations, floodlights are usually installed on the boom for lighting to assist the crane in night operations and improve the surrounding brightness. In order to ensure the normal operation of the floodlights, it is necessary to regularly maintain and inspect the floodlights. In order not to affect the operation of the equipment on the boom, the floodlights are generally fixed on the outside of the boom, making it difficult for maintenance personnel to inspect the floodlights. Therefore, it is necessary to ensure that the floodlights do not affect the operation of the boom when in use, and that the maintenance personnel can easily access the floodlights during maintenance.

[0003] For example, the patent application number is 202321481603.9, and the announcement date is 2023.10.31. The patent document discloses a support bracket for a floodlight of an offshore crane and an offshore crane, which solves the problem in the prior art that the bracket of the floodlight cannot adjust the illumination angle of the floodlight in real time as the angle of the boom changes, and has the beneficial effect of avoiding large shaking of the floodlight. The specific scheme is as follows: A support bracket for a floodlight of an offshore crane, comprising a fixed bracket and a flip bracket, the fixed bracket is Z-shaped, one side of the fixed bracket is fixed to the boom of the offshore crane, and the other side of the fixed bracket is connected to one end of the flip bracket, and the flip bracket can be flipped to a set angle relative to the fixed bracket, and a damper is connected between the fixed bracket and the flip bracket, and the damper is tilted downward relative to the vertical section of the fixed bracket.

[0004] In the above documents, the fixed bracket is Z-shaped, and a damper is provided between the fixed bracket and the flip bracket. When the floodlight needs to be installed or removed, the damper is removed and the flip bracket is flipped clockwise relative to the fixed bracket to install or remove the floodlight. After the floodlight is installed or removed, it is flipped counterclockwise and the damper is installed. In the process of rotating the flip bracket, it is necessary to start from the installation position of the floodlight. When the fixed bracket is set on the outside of the boom, the floodlight is far away from the boom, and it is difficult for maintenance personnel to contact the floodlight, and it is even more difficult to rotate the flip bracket, which makes it inconvenient to carry out maintenance. At the same time, the above structure adjusts the angle of the floodlight by rotating the flip bracket so that the flip bracket rotates up and down around the fixed bracket. The angle of the floodlight cannot be adjusted left and right within the plane where the fixed bracket is located, so as to adapt to the lighting requirements of different positions. Summary of the Invention

[0005] The utility model provides a mounting bracket for a crane floodlight, which is convenient for maintenance and replacement and can be used for angle adjustment within the plane where a fixing plate is located.

One end of the support plate 12 is connected to the fixing plate 11, and one end of the connecting plate 13 is connected to the fixing plate 11. The fixing plate 11 and the mobile frame 2 are rotatably connected. One end of the support plate 12 and the connecting plate 13 are respectively connected to one side of the fixing plate 11, and the other end of the support plate 12 and the connecting plate 13 are respectively detachably connected to the boom 5. The support plate 12 and the connecting plate 1 3 provides support for the fixed plate 11, which is connected to the boom 5 through the support plate 12 and the connecting plate 13. The other side of the fixed plate 11 is rotatably connected to the mobile frame 2, and the mobile frame 2 is rotatably arranged within the other side of the fixed plate 11. The mobile frame 2 is provided with a floodlight 4. When the floodlight 4 needs to be replaced or repaired, it is only necessary to remove the connection between the connecting plate 13 and the boom 5 and rotate the support plate 12 so that the support plate 12 drives the fixed plate 11 closer to the boom 5, thereby bringing the floodlight 4 closer to the boom 5, making it easier to repair and replace the floodlight 4.

[0033] like Figure 1-3 As shown, the fixed plate 11 is provided with a first ear plate 111 and a second ear plate 112. The fixed plate 11 is provided with the first ear plate 111 to provide a connection position for the support plate 12, so that the support plate 12 can be fixedly connected to the fixed plate 11, thereby enhancing the stability between the fixed plate 11 and the support plate 12 and the convenience of connection. The fixed plate 11 is provided with the second ear plate 112 to provide a connection position for the connecting plate 13, so that the connecting plate 13 can be hinged to the fixed plate 11, thereby enhancing the stability between the connecting plate 13 and the fixed plate 11 and the convenience of connection.

[0034] A first connecting member 121 is provided on one side of the support plate 12. Since the support plate 12 plays a major supporting role for the fixed plate 11, two first connecting members 121 are provided at the position of the boom 5 corresponding to the support plate 12. The two first connecting members 121 are respectively arranged along the width direction of the support plate 12, that is, the two first connecting members 121 are respectively located on both sides of the support plate 12, which can effectively increase the stability of the first connecting member 121 to the support plate 12. Before the support plate 12 is connected to the boom 5, the first connecting member 121 is welded to the corresponding position of the boom 5, and then the first connecting member 121 is connected to the support plate 12.

[0035] A second connecting member 131 is provided on one side of the connecting plate 13. Since the connecting plate 13 plays an auxiliary supporting role for the movable frame 2, two second connecting members 131 are provided at the position of the boom 5 corresponding to the connecting plate 13. Before the connecting plate 13 is connected to the boom 5, the second connecting member 131 is welded to the corresponding position of the boom 5, and then the second connecting member 131 is connected to the connecting plate 13. Under the action of the support plate 12 and the connecting plate 13, the fixed plate 11 can be connected to the boom 5.

[0041] When it is necessary to inspect and repair the floodlight 4, the connection between the connecting plate 13 and the second connecting member 131 is removed, and the support plate 12 is rotated so that the support plate 12 drives the fixing plate 11 closer to the boom 5, thereby bringing the floodlight 4 closer to the boom 5, making it easier to inspect and replace the floodlight 4. After the inspection is completed, the second connecting member 131 is connected to the connecting plate 13;

[0042] When the movable frame 2 needs to be rotated, the first bolt 25 and the second bolt 27 are loosened and the movable frame 2 is rotated. At this time, the movable frame 2 rotates along the groove 30. When the designated position is reached, the first bolt 25 and the second bolt 27 are tightened to complete the angle adjustment of the movable frame 2.
