Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

referring to fig. 1 to 4, the utility model discloses a lifting operation platform, which comprises a bracket 1, an operation platform 2 and a lifting mechanism, wherein the lifting mechanism comprises a plurality of rotating sheets 4 and a push rod 3, one end of each rotating sheet is hinged on the bracket 1; the free ends of the rotating pieces 4 are further connected with the operating platform 2 through a connecting plate 10, one end of the connecting plate 10 is hinged with the rotating pieces 4, the free ends of all the rotating pieces 4 are further hinged with a horizontal pushing frame, one end of the push rod 3 is hinged on the support 1 or the operating platform 2, the other end of the push rod 3 is hinged on the horizontal pushing frame, when the front end of the push rod 3 is located at one end of a working path, the front end of the push rod is just parallel to the ground, and the operating platform 2 is in the highest state; when the front end of the push rod 3 is positioned at the other end of the working path, the front end is just parallel to the ground, and the operating platform 2 is in the lowest state. When the operation table 2 is at the lowest position, a large starting force is needed for lifting; in the highest position, the operator station 2 is often subjected to some force, requiring a greater holding force. If the push rod 3 is not horizontal at this time, and has a component force in the vertical direction, a certain waste of the pushing force is caused, which is why the push rod 3 is selected to have a larger pushing force than the theoretical pushing force. When the push rod 3 is kept horizontal in these two states, the difference between the thrust force calculated by the angle of the rotary piece and the hinge position and the actually required thrust force is not large, and the push rod 3 with the slightly larger thrust force is selected. The main reason for this problem, which has not been solved by the person skilled in the art, is that it is not intuitive whether these two states can be simultaneously leveled, in conventional designs the angle of the push rod 3 always increasing or decreasing. In the specific installation, in order to have enough installation position, be equipped with first connecting plate 7 on operation panel 2, push rod 3 front end articulates on first connecting plate 7, be equipped with second connecting plate 8 on rotor plate 4, the flat push frame with second connecting plate 8 is articulated. First connecting plate 7 and second connecting plate 8 draw push rod 3 one end down, and the other end draws high, guarantees that push rod 3 can realize the level at least in certain angle, and the one end that is connected to the flat push frame even can be higher than the one end of connecting on operation panel 2. Of course, the first connecting rod and the second connecting rod can also be obtained by deforming the corresponding positions. The two opposite rotating sheets 4 are fixed through the connecting shaft 9, and the rotation of the rotating sheets 4 can be realized by controlling the movement of the connecting shaft 9. In the ascending process, the free end of the rotating sheet 4 always ascends, the operation table 2 ascends the same as the free end, the push rod 3 is supposed to be horizontal in the highest state and the lowest state, the second connecting plate 8 and the rotating sheet 4 form a certain angle, the highest point of the second connecting plate 8 changes from low to high and low relative to the rotating sheet 4, before and after the rotating sheet 4 rotates, the position of the hinge joint of the second connecting plate 8 and the horizontal rod 5 and the position of the hinge joint of the push rod 3 and the first connecting plate 7 change as shown in fig. 5, wherein arrows indicate the relative moving track of the horizontal frame, and the relative horizontal position is unchanged before and after the moving. If the position where the push rod 3 is hinged to the first link plate 7 is the same as the height of the two points, the push rod 3 is in a horizontal state at the highest and lowest positions of the elevating platform. In the process, after the rotation angle of the second connecting plate 8 in the lifting process is determined, the included angle formed by the free end of the second connecting plate 8 and the vertical direction is selected to be half of the rotation angle, and then the operation can be realized.

The horizontal push frame comprises two parallel horizontal rods 5 and a horizontal push rod 63 fixedly connected with the two horizontal rods 5, wherein two ends of each horizontal rod 5 are hinged to the two rotating sheets 4 respectively, and the hinged shafts are parallel to the width direction of the operating platform 2. During actual installation, the four rotating pieces 4 are arranged, the positions are stable and not wasted, the four rotating pieces 4 are controlled to move simultaneously by the aid of the horizontal pushing frame, the four rotating pieces move simultaneously under the condition that the initial angles are consistent, and the horizontal pushing frame is always kept horizontal. Other connection means may be used to achieve this effect, keeping the movement of the rotating blades 4 consistent.

The push rod 3 is driven by a motor. The electric push rod 3 has higher precision and is convenient to set and control. The bottom of the support 1 is provided with a plurality of trundles 11, so that the movable support is convenient to move and use. The support 1 is provided with a buffer piece, and the lifting platform can be partially supported through the buffer piece after falling.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
