[0021] Referring to Figure 1-Figure 2 , a mobile lifting device of this embodiment includes a base 1 and a driving mechanism 2 and a bracket 3 arranged thereon. There are two brackets 3, which are fixedly arranged on the base 1 in parallel. A transmission mechanism is arranged between the two brackets 3. The transmission mechanism includes a chain 4 and two sprockets 5. The two sprockets 5 are respectively mounted on the top of the bracket 3 and the base 1 through support shaft seats, and the chain 4 is sleeved on the two sprockets 5. The driving mechanism 2 includes a stepping motor, a speed reducer and a transmission shaft. The output shaft of the stepping motor is connected to the input shaft of the speed reducer, and the output shaft of the speed reducer is connected to the sprocket 5 located on the base 1 through the transmission shaft. Then, the driving mechanism 2 drives the chain 4 to transmit. A loading platform 6 is arranged on the chain 4 and moves up and down on one side of the bracket 3 along with the chain 4. The loading platform 6 is of a folding structure, and an auxiliary mechanism 7 is arranged on the side of the bracket 3 opposite to the loading platform 6.

[0022] In addition, a guide wheel 8 is also arranged on the base 1, which is on the same side of the bracket 3 as the auxiliary mechanism 7. The auxiliary mechanism 7 includes a mounting seat 71, an auxiliary wheel 72 and an auxiliary rod 73. The mounting seat 71 is detachably arranged on the side of the bracket 3. A row of mounting holes 31 are opened on the side of the bracket 3. The mounting seat 71 is connected to the mounting holes 31 by bolts, and the mounting seat 71 can be removed and fixed to another mounting hole 31 according to the use to adjust the position of the auxiliary mechanism 7. The auxiliary wheel 72 is rotatably arranged in the inner groove of the mounting seat 71 through a rotating shaft, and the auxiliary rod 73 is rotatably arranged on the mounting seat 71 through a pin shaft.

[0023] Referring to Figure 3-4, the load platform 6 includes a back panel 61, a back frame 62, a load board 63 and rollers 64. The back panel 61 is rotatably connected to the load board 63 through a pin shaft 65. The back frame 62 is fixed to the back of the back panel 61. The back frame 62 is fixedly arranged on the chain 4 through a connecting rod 66. The rollers 64 are arranged on the back frame 62 through a support shaft 67. The rollers 64 are embedded in the inner sandwich layer 32 of the bracket 3. The rollers 64 play a role in stabilizing the movement when the load platform 6 moves up and down with the chain 4.

When in use, the load board 63 can be rotated back to the horizontal position, which is convenient to operate. At the same time, the setting of the first rotating rods 68 and the second rotating rods 69 limits the rotation of the load board 63 to 0° - 90°, avoiding the situation that the load board 63 rotates at too large an inclination angle and cannot support the materials.

[0025] When the mobile lifting device of the present application is used in cooperation with a high machine platform or a high shelf, it can be connected to the fixed part of the machine platform or the shelf through the auxiliary rod 73 to improve the overall stability and avoid the device from tilting or being inverted. The detachable design of the mounting seat 71 also facilitates adjusting the position of the auxiliary mechanism 7 on the bracket 3 to adapt to the reinforcement height of the specific working occasion. At the same time, the setting of the auxiliary wheels 72 in the auxiliary mechanism 7, combined with the guide wheels 8, can lay the mobile lifting device flat, which is convenient for the movement of the device. Moreover, it can carry materials vertically up and down in the vertical state and also realize the horizontal lateral handling of materials in the horizontal state, with strong adaptability and labor saving.
