Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a bridge double-beam crane. Background Technique

[0002] For example, a bridge double-beam crane with the patent publication number CN217996582U includes two support beams. The upper surface of the support beam is slidably connected with a first moving block through a slide rail. Two connecting plates are fixed between the two first moving blocks. The upper surface of the two connecting plates is slidably connected with a moving plate through a slide rail. An electric hoist is fixed inside the moving plate, and a hook mechanism is arranged on the lower surface of the electric hoist. In this bridge double-beam crane, through the arranged buffer mechanism, after an obstacle collides with the second baffle, it drives the second fixed block and the hinged rod to move together, and compresses the first spring and pushes the second moving block to move. The second moving block compresses the rubber block. At this time, the second fixed block will reset under the dual action of the first spring and the rubber block, so that the second baffle resets. The buffering effect is good, which can effectively prevent the crane from being damaged due to colliding with obstacles such as walls during movement, and improves the protection effect.

[0003] However, during the use of the above equipment, due to the setting of the internal support beam, it is easy to generate vibration during operation, and it is easy to tilt or be unstable, reducing the safety of the equipment under heavy load. Therefore, in view of this situation, we propose a more convenient and practical crane to meet the use requirements. Content of the Utility Model

A sliding block is slidably connected to the top of the sliding bar. A lifting mechanism is arranged on the top of the anti-tilting mechanism. The lifting mechanism includes two crossbeams, and an electric hoist is installed on the top of the crossbeams.

[0006] Furthermore, a driving gear is rotatably connected to one side of the top of the sliding block, and a driven gear is rotatably connected to the other side.

[0019] During the logistics transportation process, a crane needs to be used. The crane provided by the present invention is specifically used for the cargo lifting operation during the logistics transportation process. During the process of using this equipment for lifting operations, it should be noted that the rated load of the crane must be strictly observed, and overloading operations are not allowed to avoid causing equipment failures or accidents. Carefully check the items to be lifted, confirm their weight, shape, and stability to ensure safety during the lifting process. During the lifting operation, other staff should stay away from the lifting area to ensure a safe distance and avoid accidents. Ensure that the center of gravity position of the lifted item is reasonable to avoid tilting or losing balance, which may affect safety.

[0020] As Figures 1-3 shown, the present invention provides a technical solution: a bridge double-girder crane, including an anti-tipping mechanism 1. The anti-tipping mechanism 1 includes a fixed frame 101. Both sides of the top of the fixed frame 101 are fixedly connected with anti-tipping plates 102. The inner wall of the bottom of the fixed frame 101 is fixedly connected with a tooth plate 103. The center of the top of the tooth plate 103 is fixedly connected with a sliding bar 104. The top of the sliding bar 104 is slidably connected with a sliding block 105. A lifting mechanism 2 is arranged on the top of the anti-tipping mechanism 1. The lifting mechanism 2 includes two cross beams 203. An electric hoist 204 is installed on the top of the cross beam 203.

[0021] As Figure 2As shown in the figure, on one side of the top of the sliding block 105, a driving gear 106 is rotatably connected, and on the other side, a driven gear 108 is rotatably connected. The teeth of the driving gear 106, the driven gear 108 and the toothed plate 103 are engaged with each other. On one side of the top of the sliding block 105, a servo motor 107 is installed, and the output end of the servo motor 107 is connected to the driving gear 106. On both sides of the top of the sliding block 105, anti-tilting rods 109 are fixedly connected. Grooves are provided on the inner walls of both sides of the fixed frame 101, and guide wheels 110 are rotatably connected in the grooves. The guide wheels 110 are rotatably connected to the anti-tilting rods 109. A groove is provided on the top of the fixed frame 101, and a support plate 111 is slidably connected in the groove. The support plate 111 is connected to the sliding block 105. On the top of the support plate 111, a connecting plate 112 is fixedly connected. Threaded columns 113 are fixedly connected to the four corners of the top of the connecting plate 112.

[0022] It should be noted that during the use process, first, the lifting mechanism 2 and the anti-tilting mechanism 1 are connected through the threaded columns 113 at the four corners of the connecting plate 112. Then, the servo motor 107 in the fixed frame 101 drives the driving gear 106 and the driven gear 108 to cooperate with the toothed plate 103, and under the action of the sliding strip 104, the sliding block 105 and the support plate 111 are driven to move. During this process, the anti-tilting rods 109 and the guide wheels 110 support the crane to prevent tilting, and the anti-tilting plate 102 supports the equipment from the outside. The anti-tilting mechanism 1 can effectively absorb the vibration during the operation process, reduce the swing generated by the lifted object, and improve the lifting accuracy, which is suitable for fine operation occasions.

[0023] As Figure 3 shown in the figure, the lifting mechanism 2 further includes two support beams 201.

[0024] It should be noted that during the use process, first, the support beam 201 and the base 202 are connected to the threaded columns 113. Then, the electric hoist 204 moves above the goods on the cross beam 203, and the electric hoist 204 hoists the goods through the steel wire rope 205 and the hook 206. By cooperating with the anti-tilting mechanism 1, the lifting mechanism 2 can achieve precise positioning of heavy objects, which is suitable for lifting operations that require high precision.

[0025] Working principle: During use, first connect the support beam 201 and the base 202 to the threaded column 113. Then, the servo motor 107 in the fixed frame 101 drives the driving gear 106 and the driven gear 108 to cooperate with the toothed plate 103, and under the action of the sliding bar 104, drives the sliding block 105 and the support plate 111 to move. During this process, the anti-tilting rod 109 and the guide wheel 110 support the crane to prevent tilting, and the anti-tilting plate 102 supports the equipment from the outside. Finally, the electric hoist 204 moves on the cross beam 203 to above the goods, and the electric hoist 204 hoists the goods through the steel wire rope 205 and the hook 206. This device can effectively prevent the crane from tilting or becoming unstable during operation, increasing the safety of the equipment under heavy load conditions.
