Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 2 In this embodiment, an excavation device for foundation pit construction includes a universal wheel 1, and an adjustable telescopic mechanism is provided on the top of the universal wheel 1.

[0020] In this embodiment, the adjustable telescopic mechanism includes a supporting base 2 fixedly installed on the top of the universal wheel 1, a first motor 3 fixedly installed inside the supporting base 2, a first screw 4 rotatably connected to the supporting base 2 fixedly installed on the output shaft of the first motor 3, a threaded block 5 is threadedly connected to the outer side of the first screw 4, a threaded groove is provided inside the threaded block 5, and the threaded block 5 is threadedly connected to the first screw 4 through the threaded groove, which helps the threaded block 5 to move outside the first screw 4.

[0021] Among them, a limiting groove is opened on the top of the supporting seat 2, and the threaded block 5 is slidably connected to the supporting seat 2 through the limiting groove, which helps the supporting seat 2 to limit the threaded block 5. A support plate 6 is fixedly installed on the top of the threaded block 5, and a support plate 7 is fixedly installed on the right side of the support plate 6.

[0022] In this embodiment, a reinforcement column 8 is fixedly installed between the support plate 6 and the support plate 7, a mounting box 9 is fixedly installed on the bottom of the support plate 7, a second motor 10 is fixedly installed on the top of the support plate 7, and a second screw 11 rotatably connected to the mounting box 9 is fixedly installed on the output shaft of the second motor 10. A bearing groove is opened inside the support plate 7, and the second screw 11 is rotatably connected to the support plate 7 through the bearing groove, which helps the second screw 11 to rotate.
