[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0023] See also Figure 1-4 The utility model provides a technical solution: a mobile device for elevator installation, comprising a base 1, a driving mechanism 2 is installed in the inner cavity of the base 1, a plurality of support mechanisms 3 are provided on the lower surface of the base 1, and the plurality of support mechanisms 3 are driven by the driving mechanism 2, a mounting mechanism 5 is provided on the upper surface of the base 1, and a plurality of universal moving wheels 4 are installed on the lower surface of the base 1;

[0024] The driving mechanism 2 includes a motor 21, a driving gear 23 and a transmission gear disc 25. The transmission gear disc 25 is fixedly connected to a fixed shaft 24 rotatably mounted in the middle of the inner cavity of the base 1. The output shaft of the motor 21 is drivingly connected to the rotating shaft 22. The driving gear 23 is mounted at one end of the rotating shaft 22 and meshes with the transmission gear disc 25.

[0025] The support mechanism 3 includes a column 31 and a threaded sleeve 35. The outer lower end of the column 31 is provided with an external thread 32 threadedly connected to the threaded sleeve. The upper end of the column 31 is rotatably connected to the top of the inner cavity of the base 1. The outer upper end of the column 31 is fixedly connected to a driven gear 33 meshing with the transmission gear disc 25.

[0026] The lower surface of the base 1 is provided with through holes for multiple groups of columns 31 to pass through, and a bearing sleeve 34 for the rotational connection of the column 31 is installed in each group of through holes. The bearing sleeve 34 improves the stability of the rotation of the column 31, thereby ensuring the stability of the column 31 driving the threaded sleeve 35 to rise and fall.

[0027] The outer lower end of the threaded sleeve 35 is fixedly connected to two groups of support blocks 36, the upper surfaces of the two groups of support blocks 36 are fixedly connected to guide rods 37, the upper ends of the two groups of guide rods 37 are plugged with guide cylinders 38, and the guide cylinders 38 are fixedly connected to the lower surface of the base 1. The guide rods 37 and the guide cylinders 38 limit the rotation of the threaded sleeve 35 to prevent the threaded sleeve 35 from rotating with the column 31, thereby improving the stability of the threaded sleeve 35 when it is lifted and lowered, and improving the stability of the base 1 when it is lifted and lowered.

[0028] The lower surface of the threaded sleeve 35 is fixedly connected to a non-slip base plate 39, and multiple groups of columns 31 are arranged in a rectangular array. The length of the threaded sleeve 35 is less than the height of the universal movable wheel 4. The non-slip base plate 39 can improve the anti-slip effect, increase the ground contact area, and improve the stability of the supporting base 1. At the same time, it can prevent the non-slip base plate 39 from contacting the ground and affecting the movement when the universal movable wheel 4 moves the base 1.

[0029] The mounting mechanism 5 includes a cross guide rail 51 fixedly connected to the upper surface of the base 1. The four ends of the cross guide rail 51 are slidably connected to mounting seats 53. The upper surface of the mounting seat 53 is provided with a mounting bottom groove 54. The cross guide rail 51 is used to facilitate adjustment of the position of each mounting seat 53, thereby facilitating the installation of the base 1 to support the legs of the scaffolding, thereby improving convenience.

[0030] One side of each set of mounting seats 53 is fixedly connected to a side block 55, and the upper surface of the side block 55 is threadedly connected to a locking bolt 56. The upper surface of the cross guide rail 51 is provided with multiple groups of positioning holes 57 for the locking bolts 56 to be inserted into. By inserting the locking bolts 56 into the positioning holes 57, it is convenient to fix the position of the mounting seat 53, prevent the mounting seat 53 from sliding, and improve the stability of the supporting scaffolding.

[0031] The four ends of the cross guide rail 51 are fixedly connected to the limit blocks 52, and the transmission gear plate 25 and the multiple sets of driven gears 33 are all arranged on the same plane. The limit blocks 52 are used to prevent the mounting seat 53 from sliding out of the cross guide rail 51, thereby improving the service life of the mounting mechanism 5.

[0032] When in use, the base 1 can be quickly moved to the specified position through the universal moving wheel 4, and the starting motor 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the driving gear 23 to engage the transmission gear plate 25 to rotate, and the transmission gear plate 25 is synchronously engaged with the driven gear 33 of the multiple groups of support mechanisms 3. The driven gear 33 drives the column 31 to rotate while being threadedly connected with the threaded sleeve 35. Under the limiting action of the guide rod 37 and the guide cylinder 38, the threaded sleeve 35 moves downward along the guide rod 37, so that the universal moving wheel 4 is separated from the ground and the anti-slip bottom plate 39 contacts the ground, thereby supporting the base 1, improving the stability of the base 1, reducing the use of driving equipment, and reducing the production cost of the mobile device. The position of the mounting seat 53 is adjusted according to the spacing between the legs of the scaffold, thereby facilitating the support of the scaffold during elevator installation and improving the safety of elevator installation.
