[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] In order to solve the problem that when the mobile placement rack is fixed in position, multiple universal wheels need to be fixed in sequence, which is a cumbersome operation;

[0025] like Figure 1-4 As shown, the utility model provides a liftable mobile engine placement rack, which specifically comprises an inner frame 1, a moving wheel 4 and a main support shaft 14, a bottom frame 2 is welded below the inner frame 1, the moving wheel 4 is arranged below the bottom frame 2, a side frame 9 is welded outside the inner frame 1, a main support shaft 14 is arranged on one side of the side frame 9, a handle 3 is fixedly connected to the outer wall of the main support shaft 14, mounting blocks 5 are arranged on both sides of the main support shaft 14, connecting blocks 6 are arranged on both sides of the mounting block 5, the outer wall of the side frame 9 is rotatably connected to the limited block 12 through the rotating shaft 13, and supporting steel 16 is welded on both sides below the bottom frame 2;

[0026] Ordinary moving wheels 4 are used to make the device itself movable. When its position needs to be fixed, personnel only need to adjust the position of the handle 3 to change the overall height of the placement frame, and then the support steel 16 contacts the ground to fix itself. The fixing work can be completed without manually adjusting multiple wheels. The operation is simple and quick, and the transfer work can also be achieved by placing the engine on the bottom side frame 2.

[0027] As an implementation manner, the connection block 6 is fixedly connected to the main support shaft 14 , and the connection block 6 is rotatably connected to the mounting block 5 .

[0028] As an embodiment, the mounting block 5 is connected to a support shaft 7 via a connecting block 6 on the side away from the main support shaft 14 . The support shaft 7 is rotatably connected to the bottom side frame 2 via a bearing. The connecting blocks 6 on both sides of the mounting block 5 are used to drive the position of the mounting block 5 .

[0029] As an implementation mode, a support member 15 is provided on the outer wall of the main support shaft 14, the middle part of the support member 15 is a bearing, the support member 15 is fixedly connected to the bottom side frame 2, the support member 15 is rotatably connected to the main support shaft 14, and the support member 15 enables the main support shaft 14 to maintain a rotating state.

[0030] As an implementation mode, a connecting plate 8 is provided at the connection between the mounting block 5 and the moving wheel 4. The connecting plate 8 is rotatably connected to the moving wheel 4. The connecting plate 8 is a mounting part of the moving wheel 4 and is used to support the moving wheel 4 for rotation.

[0031] As an implementation mode, a connecting frame 11 is provided at the connection of two mounting blocks 5 , both ends of the connecting frame 11 are fixedly connected, and the connecting frame 11 enables all the mounting blocks 5 to be lifted or lowered together.

[0033] As an implementation mode, the outer wall of the handle 3 is fixedly connected to the limit plate 10. When the handle 3 is adjusted, the limit plate 10 and the limit block 12 limit their own positions.

[0034] Working principle:

[0035] The engine is placed above the bottom side frame 2 in the middle of the inner frame 1, and the inner frame 1 limits the engine on the left and right sides. At this time, the supporting steel 16 under the bottom side frame 2 is in contact with the ground, and the moving wheel 4 itself cannot move. When it needs to move, the limit block 12 is manually turned, and the limit block 12 is rotated to the left through the rotating shaft 13, and then the rear end of the handle 3 can be pushed downward. At this time, the front end of the handle 3 drives the main support shaft 14 to rotate, and the main support shaft 14 moves the mounting blocks 5 on both sides downward through the connecting block 6, thereby increasing the overall height of the frame. Then the limit block 12 is reset to further limit the limit plate 10 of the handle 3, so that the frame itself remains in a lifted state, and the supporting steel 16 is not in contact with the ground at this time, and the moving wheel 4 is in contact with the ground, and the frame can be moved using the moving wheel 4.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
