DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] A hydraulic lifting platform includes a base plate 10, a lifting frame 20 is arranged on the top of the base plate 10, a platform 30 is arranged on the top of the lifting frame 20, a control box 11 is fixed to the bottom of the base plate 10, the control box 11 and the lifting frame 20 are structures used in existing hydraulic lifting platforms, so they are not described in detail. At the same time, a movable groove 22 is opened on the top of the base plate 10 for the movement of the lifting frame 20, and a first hydraulic cylinder 21 is arranged inside the lifting frame 20, wherein the first hydraulic cylinder 21 is a hydraulic cylinder used for lifting of existing hydraulic lifting platforms, and is connected and controlled in an existing manner.

[0033] In the examples of this application, please refer to Figure 1 The side of the bottom plate 10 is rotatably provided with a plurality of supporting legs 50, and the bottom of the bottom plate 10 is hinged with one end of a plurality of second hydraulic cylinders 60. The control structure and external connection structure of the second hydraulic cylinders 60 are similar to the connection control structure of the hydraulic cylinders provided with the existing hydraulic lifting platform. The other ends of the plurality of second hydraulic cylinders 60 are respectively hinged with different supporting legs 50. When the position of the hydraulic lifting platform needs to be fixed, the second hydraulic cylinders 60 are started to pull the supporting legs 50, which can drive the supporting legs 50 to move downward, so as to form a structure as shown in FIG. Figure 1 The bottom of the supporting leg 50 can be simply placed against the ground to stabilize the position, which is easy to operate and does not require the user to adjust and fix the supporting legs 50 one by one, thereby increasing the fixing efficiency, making the operation simpler and providing better stability.

[0034] Furthermore, a plurality of wheel frames 41 are fixed to the bottom of the base plate 10 , and rollers 42 are rotatably provided at the bottom of the wheel frames 41 for movement of the hydraulic lifting platform.

[0035] Furthermore, an anti-skid pad 51 is fixed to the bottom of the support leg 50 to increase the stability of the support leg 50 when it is supported on the ground.

[0036] For further examples, see Figure 1 and 2A plurality of adjustment frames 70 are also provided at the bottom of the bottom plate 10, and the support leg 50 and the second hydraulic cylinder 60 are both connected to the adjustment frame 70, wherein the adjustment frame 70 includes a slide groove 71 provided at the bottom of the bottom plate 10, and two guide grooves 72 are provided inside the bottom plate 10, which are respectively located at the front and rear sides of the slide groove 71, and a movable seat 73 is slidably provided inside the slide groove 71, and guide rails 74 are fixed on the front and rear sides of the slide groove 71, and the guide rails 74 are slidably provided inside the guide groove 72, and a fixed plate 75 hinged to the top of the support leg 50 through the hinge shaft 52 is fixed on the side of the movable seat 73, and a motor 76 is fixed inside the bottom plate 10, and the motor 76 is preferably a stepping motor or A servo motor, the output shaft of the motor 76 is fixed with a threaded rod 77 that extends threadedly into the interior of the movable seat 73. Connecting plates 62 are fixed to the sides of the support leg 50 and the bottom of the movable seat 73. The two connecting plates 62 are respectively hinged to the two ends of the second hydraulic cylinder 60 through a connecting shaft 61. When in use, the threaded rod 77 is driven to rotate by starting the motor 76, thereby driving the movable seat 73 to slide, thereby driving the support leg 50 to slide relative to the base plate 10 to change the position of the support leg 50. When the support leg 50 is farther away from the base plate 10, the supporting surface can be increased, thereby increasing the stability of the support, and when it is closer, it can be easily stored. The operation is simple and the adaptability is better.
