[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1-3 As shown, an anti-tilting device for lifting equipment includes a drive motor 3 and an adjusting screw 4 supported by a support frame 2 within a storage slot in the main body 1 of the anti-tilting device. The adjusting screw 4, in conjunction with a slider 5, supports a first connector 6 within the support frame 2. The first connector 6, in conjunction with a connecting rod 7 and a second connector 8, supports one side of the lifting arm 9 to prevent the lifting arm 9 from rotating and tilting backward on the main body 1 of the anti-tilting device. When the lifting arm 9 tilts backward, the lifting arm 9 pushes the second connector 8, the connecting rod 7, and the first connector 6. The first connector 6 then pushes the slider 5. Block 5 drives the adjusting screw 4 to drive the support frame 2. The support frame 2 is supported by the bottom anti-tilting device body 1, the side movable sleeve 10, and the support screw 11. Thus, the support frame 2, the anti-tilting device body 1, the movable sleeve 10, and the support screw 11 form a support triangle to fix the support frame 2 on the anti-tilting device body 1. The first connector 6, the connecting rod 7, and the second connector 8 support the lifting arm 9 on the fixed support frame 2 through the adjusting screw 4 and the slider 5, thereby stabilizing the lifting arm 9 and preventing it from tilting backward.

[0023] When the first connector 6, connecting rod 7, and second connector 8 support the lifting arm 9 on the support frame 2 through the adjustment screw 4 and slider 5, the drive motor 3 is started. The output end of the drive motor 3 drives the adjustment screw 4 to rotate. The rotation of the adjustment screw 4 drives the slider 5 to slide within the support frame 2 through the thread, thereby causing the first connector 6 to rise and fall within the support frame 2. The support angle of the first connector 6, connecting rod 7, and second connector 8 on the lifting arm 9 is adjusted according to the rotation angle of the lifting arm 9 on the anti-tilting device body 1. This can meet the support of the lifting arm 9 at different angles, thereby flexibly moving and supporting the lifting arm 9 and preventing the angle from being too large or too small, which would affect the support effect.

[0024] Example 2, as Figure 4 and Figure 5 As shown, an anti-tilting device for lifting equipment involves a movable sleeve 10 rotating within a groove in the main body 1 of the anti-tilting device. During transportation, the support screw 11 is unscrewed from one side of the support frame 2, causing the movable sleeve 10 to fall into the groove in the main body 1 of the anti-tilting device for storage. Inside the support frame 2, the drive motor 3 drives the adjusting screw 4, which in turn drives the slider 5, which in turn drives the first connector 6 to be stored inside the support frame 2. Pulling the support frame 2 down allows it to be stored in the storage slot in the main body 1 of the anti-tilting device, thus conveniently storing the support frame 2, the support screw 11, and the movable sleeve 10, reducing the overall footprint and facilitating subsequent storage and transportation.

[0025] It needs to be explained that the utility model is a kind of anti-back tilting device for hoisting equipment, when using, through movable sleeve 10 cooperation support screw rod 11 support fixed support frame 2 on anti-back tilting device main part 1, support frame 2 cooperation adjusting screw rod 4 and sliding block 5 support first connecting head 6, connecting rod 7 and second connecting head 8 in hoist arm 9 rear side, also utilize drive motor 3 drive adjusting screw rod 4 drive lifting adjustment first connecting head 6 height control first connecting head 6, connecting rod 7 and second connecting head 8 in hoist arm 9 rear side support angle of inclination, guarantee effective support, also through the storage groove of anti-back tilting device main part 1 set up and store support frame 2, reduce overall floor area and facilitate subsequent storage and transportation.

[0026] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
