The anti-skid pad 151 is made of rubber material, which can adapt to the smooth ground and improve the ground contact stability of the long ground contact board 15. The left and right sides of the long ground contact board 15 are fixedly installed with a stabilizing mechanism 16 with the same structure. The two telescopic mechanisms 14 each include a fixed cylinder 141. The two fixed cylinders 141 are fixedly installed on the top of the inner wall of the driving cabin 12. The inner walls of the two fixed cylinders 141 are slidably installed with a sliding chassis 142. The bottoms of the two sliding chassis 142 are fixedly installed with moving rods 143. The bottom ends of the two moving rods 143 respectively penetrate to the bottom of the two fixed cylinders 141 and are fixedly connected to the top of the long ground contact board 15.

[0022] The lifting platform 3 drives the scissor-type cross steel pipe 2 to lift and lower through the built-in motor in the mobile base 1. When lifting and lowering is required, the electric push rod 13 in the driving cabin 12 at the bottom of the mobile base 1 is started, thereby driving the long ground-touching board 15 to steadily descend until the wear-resistant and anti-skid pad 151 touches the ground and is slightly lifted, so that the driving wheel 11 is slightly off the ground, so that the entire mobile base 1 is stably placed. At the same time, when the long ground-touching board 15 descends, the moving rod 143 connected to its top slides in the fixed tube 141 to maintain the stability of the up and down movement of the long ground-touching board 15. When the mobile base 1 needs to be moved, it is only necessary to start the electric push rod 13 to drive the long ground-touching board 15 to move upward and retract until the driving wheel 11 touches the ground.

[0023] like Figure 4 As shown, the two stabilizing mechanisms 16 each include a ground contacting bottom plate 161, the tops of the two ground contacting bottom plates 161 are fixedly mounted with driving columns 162, the driving columns 162 are provided with a lifting chute 163 which passes through from left to right, a lifting motor 164 is fixedly mounted on the top of the driving columns 162, the output shaft of the lifting motor 164 passes through the inner cavity of the lifting chute 163 and is fixedly mounted with a lifting screw 165, a lifting block 166 is threadedly mounted on the outer wall of the lifting screw 165, the lifting block 166 is slidably connected with the lifting chute 163, a movable long rod 167 is fixedly mounted on one end of the lifting block 166 away from the movable base 1, an extending long plate 168 is movably mounted on one side of the movable long rod 167 away from the lifting block 166, and a stabilizing plate 169 is movably mounted on the bottom end of the extending long plate 168;

[0024] When the long ground contact plate 15 descends, it will drive the ground contact bottom plates 161 on the left and right sides to contact the ground at the same time, and simultaneously start the lifting motor 164 at the top of the driving column 162 on the top of the two ground contact bottom plates 161, so that the lifting screw 165 rotates in the lifting slide groove 163, and the lifting screw 165 is connected with the lifting block 166 by thread, so that the lifting block 166 can move downward stably in the lifting slide groove 163, and the movable long rod 167 and the extended long plate 168 are connected flexibly, so that the two extended long plates 168 are tilted and moved toward the two sides of the movable base 1, and the stabilizing plate 169 is driven to move out of the groove opened in the ground contact bottom plate 161, so as to increase the overall ground contact area of ​​the long ground contact plate 15 and further improve the stability.

[0025] like Figure 5 As shown, a stabilizing cabin 1611 is provided inside each of the two ground contacting bottom plates 161, and telescopic rods 1612 are fixedly installed at the front and rear of the inner wall of the stabilizing cabin 1611 close to the moving base 1, and a groove is provided on the side of the ground contacting bottom plate 161 away from the ground contacting long plate 15, and the telescopic output ends of the two telescopic rods 1612 are both penetrated into the groove provided in the ground contacting long plate 15 and are fixedly connected to the side of the stabilizing plate 169 close to the ground contacting bottom plate 161, and the stabilizing plate 169 is engaged with the groove provided in the ground contacting long plate 15, and a reset tension spring 1614 is fixedly connected to the middle part of the inner wall of the ground contacting bottom plate 161 close to the ground contacting long plate 15, and a tension spring hole 1613 penetrating to the groove is provided in the middle part of the inner wall of the stabilizing cabin 1611 away from the ground contacting long plate 15, and the other end of the reset tension spring 1614 penetrates the tension spring hole 1613 into the groove and is fixedly connected to the middle part of the stabilizing plate 169 close to the stabilizing cabin 1611;

[0026] When moving, the stabilizing plate 169 utilizes the telescopic rod 1612 in the stabilizing cabin 1611 to maintain the stability of translation, and at the same time pulls the reset spring 1614 to lengthen it, and then reverses the lifting motor 164 to drive the lifting screw rod 165 to reverse, so that when the lifting block 166 rises, the stabilizing plate 169 can be reset, and relies on the resilience of the reset spring 1614 to quickly and stably reset.

[0027] The following is a detailed description of the working principle of the mobile lifting platform.

[0028] like Figure 1-5As shown, the lifting platform 3 drives the scissor-type cross steel pipe 2 to lift and lower through the built-in motor in the mobile base 1. At the same time, when lifting and lowering is required, the electric push rod 13 in the driving cabin 12 at the bottom of the mobile base 1 is started, thereby driving the long ground-contacting board 15 to steadily descend until the wear-resistant and non-slip pad 151 touches the ground and is slightly lifted, so that the driving wheel 11 is slightly off the ground, so that the entire mobile base 1 is stably placed. At the same time, when the long ground-contacting board 15 descends, the moving rod 143 connected to its top slides in the fixed cylinder 141 to maintain the stability of the up and down movement of the long ground-contacting board 15. When the long ground-contacting board 15 descends, it will drive the ground-contacting bottom plates 161 on the left and right sides to contact the ground at the same time, and simultaneously start the lifting motor 164 at the top of the driving column 162 on the top of the two ground-contacting bottom plates 161, so that the lifting screw rod 165 is in the lifting slide groove 1 63, and the lifting screw rod 165 is connected with the lifting block 166 by thread, so that the lifting block 166 can move downward stably in the lifting slide groove 163, and the movable long rod 167 is connected with the extended long plate 168 by the movable connection, so that the two extended long plates 168 are tilted and moved to the two sides of the movable base 1, and the stabilizing plate 169 is driven to move out of the groove opened in the ground contact bottom plate 161, thereby increasing the overall ground contact area of ​​the ground contact long plate 15 and further improving the stability. When moving, the stabilizing plate 169 uses the telescopic rod 1612 in the stabilizing cabin 1611 to maintain the stability of translation, and at the same time pulls the reset spring 1614 to stretch it, and then drives the lifting screw rod 165 to reverse by reversing the lifting motor 164, so that when the lifting block 166 rises, the stabilizing plate 169 can be reset, and relies on the resilience of the reset spring 1614 to quickly and stably reset.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
