[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figures 1-4The illustrated lifting outrigger with an auxiliary support structure includes a telescopic outrigger 1, an auxiliary outrigger 2, and a base plate 3. Both the telescopic outrigger 1 and the auxiliary outrigger 2 are hinged to the base plate 3, which increases the contact area with the ground, ensuring the stability of the lifting device. The telescopic outrigger 1 is driven by a hydraulic cylinder and can extend and retract vertically to lift or lower the lifting platform (not shown). The telescopic outrigger 1 can also be driven by a heavy-duty screw module. The auxiliary outrigger 2 is shorter than the telescopic outrigger 1. The upper end of the auxiliary outrigger 2 is hinged to one side of the upper end of the telescopic outrigger 1. The upper end of the auxiliary outrigger 2 can be directly hinged to the side of the telescopic outrigger 1 or hinged to the lower end face of the lifting platform. When the telescopic outrigger 1 is in the extended state, the auxiliary outrigger 2 is vertical relative to the ground.

[0019] like Figures 1-4 As shown, the auxiliary support leg 2 includes a first support leg 21 and a second support leg 22. An elongated oval connecting groove 211 is fixed on the side of the first support leg 21. The length direction of the connecting groove 211 is parallel to the length direction of the first support leg 21, and the connecting groove 211 is located on the side of the first support leg 211 close to the telescopic support leg 1.

[0020] A connecting shaft 221 is fixed to the side of the second leg 22, and the connecting shaft 221 is located on the side of the second leg 22 closer to the telescopic leg 1. The connecting shaft 221 is inserted into the connecting groove 211, so that the first leg 21 and the second leg 22 can be flipped and folded away from the telescopic leg 1 around the connecting shaft 221.

[0021] like Figures 1-4 As shown, a snap-fit ​​block 212 is fixed to the upper end of the first leg 21. The snap-fit ​​block 212 protrudes from the connecting groove 211 and the end of the snap-fit ​​block 212 is arc-shaped. An elongated guide groove 213 is provided on the side of the snap-fit ​​block 212, and the length direction of the guide groove 213 is parallel to the length direction of the first leg 21.

[0022] The lower end of the second leg 22 is provided with a snap-fit ​​groove 222 that mates with the snap-fit ​​block 212. A limiting hole 223 is provided on the side wall of the snap-fit ​​groove 222. The position of the limiting hole 223 mates with the position of the guide groove 213. A pin 4 is detachably installed in the limiting hole 223. A guide hole 224 is also provided on the side wall of the snap-fit ​​groove 222. The guide hole 224 is located on the side of the second leg 22 near the connecting shaft 221.

[0023] The working principle of this application embodiment is as follows:

[0024] When the telescopic outrigger 1 is in operation, it is first extended to its maximum length. At this time, the first outrigger 21 and the second outrigger 22 are on the same vertical line, and the limiting hole 223 coincides with the guide groove 213. The pin 4 is inserted into the limiting hole 223, and the telescopic outrigger 1 is driven to descend slowly. At this time, under the action of the pin 4 and the guide groove 213, the locking block 212 is inserted into the locking groove 222, so that the first outrigger 21 supports the second outrigger 22, preventing the first outrigger 21 and the second outrigger 22 from flipping over, thereby providing stable auxiliary support for the telescopic outrigger 1.

[0025] When the telescopic outrigger 1 is retracted, the telescopic outrigger 1 is first extended to its maximum length. Then, the pin 4 is pulled out from the limiting hole 223 and inserted into the guide hole 224. Then, the telescopic outrigger 1 is driven to descend slowly. When the top of the locking block 212 contacts the pin 4 in the guide hole 224, the pin 4 pushes the locking block 212 to the side into the locking groove 222, thereby preventing the auxiliary outrigger 2 from getting stuck during descent.

[0026] The technical solutions provided in this application have at least the following technical effects or advantages:

[0027] 1. By installing foldable auxiliary legs on the sides of the telescopic outriggers, the auxiliary outriggers can provide additional support for the telescopic outriggers during operation, reducing the pressure of the equipment on the telescopic outriggers, extending the service life of the telescopic outriggers, and ensuring the safety of equipment use.

[0028] 2. By opening guide holes on the auxiliary outriggers and installing pins in the guide holes, the folding of the telescopic outriggers can be guided by the pins when the auxiliary outriggers are retracted, so as to avoid the auxiliary outriggers getting stuck and ensure the safe use of the equipment.

[0029] 3. By using auxiliary outriggers to provide auxiliary support for the lifting platform, the conflict between personnel and equipment safety and operating procedures under heavy equipment that achieves lifting, working, and other objectives through hydraulic cylinder lifting and gravity pressing can be resolved.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
