Abstract
Description
Technical Field
[0001] This utility model belongs to the field of support device technology, specifically relating to a multi-degree-of-freedom support leg suitable for lifting and lateral movement of large trolleys. Background Technology
[0002] Traditional support leg technology focuses on lifting in a single vertical direction. Its core function relies on hydraulic cylinders, electric push rods, or mechanical screw structures to achieve height adjustment. Lateral position adjustment usually depends on the overall trolley movement drive system, resulting in low efficiency, poor flexibility, and large space occupation. If an auxiliary lateral movement device is used, it needs to be installed separately, increasing structural complexity and maintenance costs. Due to the rapid development of intelligent technology, the demand for intelligent systems in large construction machinery trolleys is increasing. In intelligent control, the requirements for overall position control are very strict. Only by ensuring that the trolley is in the set position can the subsequent functions be fully automated. Therefore, the trolley needs to be able to achieve precise lateral movement to adjust its precise position. Based on this, we propose a support leg that integrates lifting and lateral movement functions. Utility Model Content
[0003] The purpose of this invention is to provide a multi-degree-of-freedom support leg for lifting and lateral movement of large trolleys, aiming to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-degree-of-freedom support leg for lifting and lateral movement of a large trolley, comprising a support foot, a slide rail fixedly installed at the top of the support foot, a lateral moving device slidably installed on the surface of the slide rail, a lifting device installed at the top of the lateral moving device, and a vertical plate provided at one end of the top of the support foot.
[0005] The lateral movement device includes a slider that is slidably connected to a slide rail. A support plate is installed at the top of the slider, a mounting cover is installed at the top of the support plate, and a first connecting plate is installed at the top of the mounting cover. First fixing holes are provided at the four corners of the first connecting plate. A first mounting seat is installed at one end inside the mounting cover.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figures 1-5 The present invention provides the following technical solution: a multi-degree-of-freedom support leg for lifting and lateral movement of a large trolley, including a support foot 1, a slide rail 2 fixedly installed at the top of the support foot 1, a lateral moving device 3 slidably installed on the surface of the slide rail 2, a lifting device 4 installed at the top of the lateral moving device 3, and a vertical plate 5 provided at one end of the top of the support foot 1.
[0019] In this embodiment, the lateral moving device 3 includes a slider 31 that is slidably connected to the slide rail 2. A support plate 32 is installed at the top of the slider 31. A mounting cover 33 is installed at the top of the support plate 32. A first connecting plate 34 is installed at the top of the mounting cover 33. First fixing holes 35 are provided at the four corners of the first connecting plate 34. A first mounting seat 36 is installed at one end inside the mounting cover 33. The first mounting seat 36 is connected to the fixed end of the lateral moving cylinder 37 by bolts. A second mounting seat 38 is installed on the side of the vertical plate 5. The telescopic end of the lateral moving cylinder 37 is connected to the second mounting seat 38 by bolts.
[0020] Specifically, the lifting device 4, in conjunction with the support foot 1, can lift the trolley to achieve a supporting effect. If the position of the trolley needs to be moved laterally during operation, the lateral movement cylinder 37 causes the support plate 32 to move the slider 31 along the slide rail 2. The lifting device 4 is fixed to the top of the first connecting plate 34. In this way, the lifting device 4 can drive the entire machine to adjust its lateral position along the slide rail 2. This adjustment method is simple, convenient, and responsive, effectively improving construction efficiency. Moreover, the telescopic end of the lateral movement cylinder 37 is connected to the second mounting base 38 by bolts. Therefore, after removing the bolts, the slider 31 can be slid along the slide rail 2 and disengaged from the slide rail 2, thus allowing the lateral movement device 3 to be easily disassembled and maintained.
[0021] In this embodiment, the lifting device 4 includes a second connecting plate 41, a support cylinder 42 is installed at the top of the second connecting plate 41, and second fixing holes 43 are provided at the four corners of the second connecting plate 41. The first connecting plate 34 and the second connecting plate 41 are connected and fixed to each other by bolts installed in the first fixing holes 35 and the second fixing holes 43. A third mounting seat 44 is installed at the bottom of the support cylinder 42. The third mounting seat 44 is connected to the fixed end of the lifting cylinder 45 by bolts. The lifting cylinder 45 is installed inside the support cylinder 42. A sleeve 46 is sleeved on the outside of the support cylinder 42. A fourth mounting seat 49 is installed at the top of the sleeve 46. The fourth mounting seat 49 is connected to the telescopic end of the lifting cylinder 45 by bolts. A third connecting plate 47 is installed at the top of the sleeve 46. A connecting hole 48 is provided at the four corners of the third connecting plate 47. The third connecting plate 47 is connected to the trolley by bolts installed in the connecting holes 48.
[0022] Specifically, the third connecting plate 47 is fixed to the trolley via the connecting hole 48 and bolts, thereby fixing the support leg to the trolley. When the support leg is working, the lifting cylinder 45 works to make the support cylinder 42 descend along the sleeve 46 and make the support foot 1 contact the ground. The continuous operation of the lifting cylinder 45 can lift the trolley to achieve the support effect. Since the first connecting plate 34 and the second connecting plate 41 are fixed by bolts installed in the first fixing hole 35 and the second fixing hole 43, the lifting device 4 and the lateral moving device 3 can be disassembled, which makes it easier for the staff to maintain.
[0023] In this embodiment, a plurality of first stiffening plates 6 are connected between the support plate 32 and the side wall of the first connecting plate 34 and the mounting cover 33, and a plurality of second stiffening plates 7 are installed on the side of the support foot 1.
[0024] Specifically, the first stiffener 6 can enhance the strength of the mounting cover 33, thereby increasing the service life of the transverse hydraulic cylinder 37, while the second stiffener 7 can enhance the strength of the support leg 1, thereby improving the support stability of the support leg.
[0025] In this embodiment, several anti-slip pads 8 are installed at the bottom of the support foot 1.
[0026] Specifically, the anti-slip pad 8 can improve the anti-slip properties of the support leg 1, thereby enhancing the support stability of the support leg.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
