[0023] The specific structure of the rotation support device is as follows: the structure of the rotation support device includes a fixed sleeve 2, a handle shaft 3 and a handle 4. The side walls of the lower ends of the columns on both sides of the bracket 1 are provided with mounting holes, and the fixed sleeve 2 that passes through the mounting holes at the lower ends of the columns is fixedly connected to the columns. The fixed sleeve 2 is provided with a handle shaft 3, and the outer end of the handle shaft 3 is fixedly connected to the handle 4. By pulling the handle 4 outward or pushing it inward, the inner end of the handle shaft 3 is separated from or connected to the connecting hole on the corresponding side wall of the cylinder cover. The fixed sleeve 2 is provided with a limiting device for limiting the handle shaft 3 that is positioned in the plug-in position or separation position with the cylinder cover.
[0024] The specific structure of the limiting device is as follows: the limiting device includes a limiting screw 5, and the outer wall of the fixing sleeve 2 is threadedly connected with a limiting screw 5 set on the same side as the handle 4. Figure 3 As shown, a connection position limiting ring groove 6 and a separation position limiting ring groove 7 are formed on the outer circumferential wall of the handle shaft 3, and the connection position limiting ring groove 6 and the separation position limiting ring groove 7 are connected through a guide groove 9 provided on the outer circumferential wall of the handle shaft 3, and the handle shaft 3 is moved by the handle 4 so that the inner end of the limiting screw 5 is adapted to the connection position limiting ring groove 6 or the separation position limiting ring groove 7, thereby realizing the limitation of the handle shaft 3 in the connection position or the separation position; specifically, the end of the handle 4 is fixed to the outer end of the handle shaft 3 by a screw; specifically, the diameter of the inner end of the handle shaft 3 is smaller than the diameter of the adaptation section of the fixed sleeve 2, and when in use, the inner end of the handle shaft 3 is connected to the connecting hole on the corresponding side wall of the cylinder cover; wherein, the structure of the positioning support device is the same as that of the rotation support device.
[0025] The specific structure of the bracket 1 is as follows: the bracket 1 adopts a door-shaped frame composed of columns on both sides and beams fixedly connected to the upper ends of the columns, and a reinforcing rib plate 10 is provided on the inner side of the connection position between the columns and the beams, and a lifting ear plate 8 for connecting to the lifting equipment is fixed in the middle of the beam of the bracket 1.
[0026] like Figure 1-2 As shown, the bracket 1 is mainly welded by channel steel 80×43×5 and steel pipe Q345B-35×6.0. The channel steel is the main frame of the bracket, and the fixing sleeve 2 welded on the bracket 1 is to ensure the installation and use of the handle shaft 3. The outer wall of the outer end of the fixing sleeve 2 is processed with an M6 threaded hole for installing the limit screw 5; Figure 3 As shown, the handle shaft 3 is designed with a plug-in position limit ring groove 6, a separation position limit ring groove 7 and a guide groove 9, which control the cylinder cover by cooperating with the limit screw 5. When the handle 4 is in the locked position, that is, when the handle 4 is in the vertical state: since the guide groove 9 and the limit screw 5 are staggered and not on the same straight line, the handle shaft 3 cannot move axially in the fixing sleeve 2, thereby playing the role of fixing the cylinder cover; when the handle 4 is in the open position, that is, Figure 2When the handle 4 is in a horizontal state, the guide groove 9 and the limit screw 5 are located on the same straight line: the handle shaft 3 can move axially in the fixed sleeve 2, and the handle 2 is pulled outward. At this time, the handle shaft 3 is separated from the cylinder head connecting hole, and the cylinder head can be flipped. After the flipping is completed, the handle shaft 3 is re-inserted into the cylinder head connecting hole and the handle 4 is rotated to the locked position. At this time, the cylinder head is fixed on the bracket 1.
[0027] This technical solution utilizes the mutual cooperation of the handle 4 and the limit screw 5 to fix the cylinder head on the bracket, thereby realizing the lifting and flipping of the cylinder head. It has a simple structure, novel design, easy operation, low cost, wide range of use, and can be promoted for use in other models.
