Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1-5 The present invention provides a folding boom hydraulic crane, including a hydraulic crane structure;
[0036] Mounting structure: The mounting structure is coaxially mounted at the rear of the hydraulic crane structure;
[0037] Hydraulic crane structure: The hydraulic crane structure includes outriggers 11, folding boom 12 and hydraulic pump 13;

[0041] Among them, the folding boom 12 is mostly made of high-strength steel, which determines the maximum lifting height and working radius of the equipment. The hydraulic pump 13 is responsible for transmitting power and controlling the boom extension, rotation and hook lifting. The outriggers 11 contact the ground and support the whole machine, improving the stability during lifting and preventing the equipment from tipping over.
[0042] Installation structure: The installation structure includes a limiting frame 21, a limiting hole 22, a pin 23, a through groove 24, a turntable 25, and a guide groove 26;

[0044] The mounting structure also includes a threaded rod 27, a screw block 28, and a socket 29;
[0045] The threaded rod 27 is fixedly connected to both ends of the turntable 25, the screw block 28 is threadedly connected to one end of the threaded rod 27, and the insertion hole 29 is opened inside the turntable 25;
[0046] The pin 23 is inserted through the inside of the socket 29. There are multiple sets of sockets 29, which are equally spaced inside the turntable 25 with the center of the turntable 25 as the center. The screw block 28 is slidably connected to the inside of the guide groove 26. One end of the turntable 25 is inserted through the through groove 24 and is set outside the top of the support leg 11. There are two sets of threaded rods 27, and the threads on the outside of the two sets of threaded rods 27 are oriented in opposite directions.
[0047] With the auxiliary cooperation between the limiting frame 21 and the limiting hole 22, when the turntable 25 is rotated, the screw block 28 can slide along the thread track outside the threaded rod 27 inside the guide groove 26, thereby adjusting the installation position of the mounting block 31.
[0048] Working principle: Before installing the articulated boom hydraulic crane;
[0049] First, depending on the location of the installation environment, pull out the pin 23 inside the limiting hole 22 to release the limitation formed by the pin 23 on the turntable 25. By rotating the turntable 25 clockwise, the threaded rod 27 fixedly connected at both ends can be rotated, and the screw block 28 can slide along the threaded track outside the threaded rod 27 inside the guide groove 26.
[0050] Next, the installation position of the mounting block 31 can be adjusted. After the mounting block 31 is slid to a suitable installation position, the pin 23 can be inserted into the limiting hole 22 again through the insertion hole 29 for limiting.
[0051] This step helps workers install the articulated boom hydraulic crane to suit different construction environments, increasing the applicability of the articulated boom hydraulic crane.
[0052] Please see Figure 4-5 As shown, this embodiment, based on the above embodiment, also includes an adjustment structure;
[0053] The adjustment structure includes a mounting block 31, a fixing hole 32, a slide groove 33, and a slider 34;
[0054] Mounting block 31 is fixedly connected to one end of screw block 28, fixing hole 32 is opened at one end of mounting block 31, sliding groove 33 is opened on the outside of mounting block 31, and slider 34 is slidably connected to the inside of sliding groove 33.
[0055] The adjustment structure also includes a connecting groove 35, a connecting plate 36, a spring mounting plate 37, a mounting hole 38, a spring buckle 39, an auxiliary plate 310, and a locking hole 311;
[0056] A connecting groove 35 is formed on the outer middle of the mounting block 31, a connecting plate 36 is slidably connected to the inside of the connecting groove 35, a spring mounting piece 37 is fixedly connected to one end of the slider 34, a mounting hole 38 is formed on one end of the spring mounting piece 37, a spring buckle 39 is fixedly connected to one end of the spring mounting piece 37, an auxiliary plate 310 is fixedly connected to the inner middle of the mounting block 31, and a locking hole 311 is formed on one end of the auxiliary plate 310.
[0057] Mounting block 31 is used to open the fixing hole 32, slide groove 33 and connecting groove 35, spring mounting plate 37 is used to open the mounting hole 38, auxiliary plate 310 is used to open the snap hole 311, slide groove 33 is used to provide space for guiding sliding of slider 34, there are two sets of spring mounting plates 37, and the mounting holes 38 opened inside the two sets of spring mounting plates 37 are different in size;
[0058] By cooperating with the mounting block 31 and the fixing hole 32, when the slider 34 inside the sliding groove 33 is slidable, the spring mounting piece 37 can be guided to slide inside the mounting block 31, thereby aligning the mounting hole 38 and the fixing hole 32.
[0059] Working principle: When faced with mounting slots of different specifications;
[0060] First, by observing the size of the mounting groove, two sets of spring mounting pieces 37 are selected. By sliding the slider 34 inside the sliding groove 33, the spring mounting piece 37, which is fixedly connected to one end of the slider 34, can be guided and slid inside the mounting block 31. At the same time, the mounting hole 38 and the fixing hole 32 at one end of the spring mounting piece 37 are aligned, and the spring buckle 39, which is fixedly connected to one end of the spring mounting piece 37, is engaged inside the buckle hole 311. This limits the position of the spring mounting piece 37 and assists in the installation of the mounting part through the fixing hole 32 and the mounting hole 38 and the mounting groove.
[0061] Next, when the articulated boom hydraulic crane is installed in different mounting slots, the connecting plate 36 inside the sliding connecting slot 35 can be used to press the spring buckle 39 that is engaged in the buckle hole 311, thereby releasing the limit formed between the spring mounting piece 37 and the auxiliary plate 310, and allowing the spring mounting piece 37 to reset under the influence of the elastic force.
[0062] This step helps workers to flexibly install the articulated boom hydraulic crane.
[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
