[0027] The other end of the flip shaft 8 passes through the adjustment seat 7 and is fixedly connected to a gear ring 11 . A fixed shell 12 is movably sleeved on the outer side of the gear ring 11 . The fixed shell 12 is movably connected to the flip shaft 8 .
[0028] In this embodiment, when it is necessary to use a bracket to assemble the engine, the engine frame is fixed to the corresponding mounting holes 10 on the mounting plate 9 by bolts and nuts. During the engine assembly process, when it is necessary to adjust the height of the installed engine frame, the motor 5 is started, and the motor 5 drives one of the screws 3 to rotate. The screw 3 drives the other screw 3 to rotate simultaneously through the transmission belt structure 4, so that the two lifting seats 6 move upward along the limit shell 2 at the same time, and the lifting seat 6 drives the adjustment seat 7 to move upward, and the adjustment seat 7 drives the flip shaft 8 and the mounting plate 9 to move upward, and the mounting plate 9 drives the installed engine frame to move upward. On the contrary, when the motor 5 is reversed, the engine frame moves downward, so that the height of the engine frame can be adjusted according to the height of the staff.
[0029] More specifically, the moving direction of the adjustment seat 7 can be controlled by controlling the forward and reverse rotation of the motor 5, thereby adjusting the height of the engine frame mounted on the mounting plate 9. The fixed shell 12 is separated from the gear ring 11, and the flip shaft 8 is rotated. The flip shaft 8 drives the mounting plate 9 and the engine frame to rotate, thereby flipping the engine frame. When the flip shaft 8 rotates, the gear ring 11 is driven to rotate. When the flip is completed, the fixed shell 12 is sleeved on the outside of the gear ring 11 to fix the gear ring 11, and the engine frame can be fixed by the flip shaft 8 and the mounting plate 9.
[0030] See also Figure 1-5 , as an implementation method for fixing the flip shaft 8: two limit rods 13 are symmetrically fixed on one side of the adjustment seat 7, and a pushing seat 14 is movably provided on each of the limit rods 13. The two pushing seats 14 are fixedly connected to the fixed shell 12, and a first spring 15 is movably sleeved on the outer side of each limit rod 13. The first spring 15 is arranged between the pushing seat 14 and the adjustment seat 7, and one end of each limit rod 13 passes through the pushing seat 14 and is fixedly connected to the limit plate 16, and the end of the flip shaft 8 close to the gear ring 11 is fixedly connected to the turning handle 17.
[0031] Specifically, when it is necessary to rotate the flip shaft 8, the fixed shell 12 is pushed to separate the fixed shell 12 from the gear ring 11, and the fixed shell 12 drives the pushing seat 14 to move along the limiting rod 13, and the first spring 15 is compressed. At this time, the turning handle 17 is turned, and the turning handle 17 drives the flip shaft 8 to rotate, and the flip shaft 8 drives the mounting plate 9 and the engine frame to rotate, so as to flip the engine frame. The rotation of the flip shaft 8 will also drive the gear ring 11 to rotate. When the flipping is completed, the fixed shell 12 is released. Under the action of the first spring 15, the fixed shell 12 is sleeved on the outside of the gear ring 11 to fix the gear ring 11. The limiting plate 16 limits it, and the engine frame can be fixed by the flip shaft 8 and the mounting plate 9.
[0032] See also Figure 1-5 , as an implementation method for installing the docking oil box 19: a placement groove 18 is provided on the base 1, and the oil receiving box 19 is slidably connected to the placement groove 18 through a track structure. One side of the base 1 is recessed inward to form a fixed chamber 20, and an L-shaped fixed block 21 is slidably connected to the fixed chamber 20 through a track structure. Both ends of the fixed block 21 respectively pass through the fixed chamber 20 and extend to the outside of the fixed chamber 20, and a plurality of second springs 22 are fixedly connected between the lower end of the fixed block 21 and the fixed chamber 20.
[0033] Specifically, the fixing block 21 is pressed downward, and the fixing block 21 moves downward along the sliding connection with the fixing chamber 20. The second spring 22 is compressed. At this time, the upper end of the fixing block 21 moves into the fixing chamber 20, and the oil collecting box 19 is moved along the sliding connection with the placement groove 18 and placed in the placement groove 18. The fixing block 21 is released, and under the action of the second spring 22, the fixing block 21 moves back to its original position along the sliding connection with the fixing chamber 20. The upper end of the fixing block 21 will extend out of the fixing chamber 20 and cover the oil collecting box 19, thereby fixing the oil collecting box 19 to the installation groove.
[0034] Working principle:
[0035] When the oil collecting box 19 needs to be installed on the base 1, the fixing block 21 is pressed downward, and the fixing block 21 moves downward along the sliding connection with the fixing chamber 20. The second spring 22 is compressed. At this time, the upper end of the fixing block 21 moves into the fixing chamber 20, and the oil collecting box 19 is moved along the sliding connection with the placement groove 18 and placed in the placement groove 18. The fixing block 21 is released, and under the action of the second spring 22, the fixing block 21 moves back to its original position along the sliding connection with the fixing chamber 20. The upper end of the fixing block 21 will extend out of the fixing chamber 20 and cover the oil collecting box 19, thereby fixing the oil collecting box 19 to the installation groove.
[0036] When the engine needs to be assembled, the engine frame is fixed to the corresponding mounting holes 10 on the mounting plate 9 by bolts and nuts. During the engine assembly process, when the installed engine frame needs to be adjusted in height, the motor 5 is started, and the motor 5 drives one of the screws 3 to rotate, and the screw 3 drives the other screw 3 to rotate simultaneously through the transmission belt structure 4, so that the two lifting seats 6 move upward along the limit shell 2 at the same time, the lifting seat 6 drives the adjustment seat 7 to move upward, the adjustment seat 7 drives the flip shaft 8 and the mounting plate 9 to move upward, and the mounting plate 9 drives the installed engine frame to move upward; when the motor 5 is reversed, the engine frame moves downward, so that the height of the engine frame can be adjusted according to the height of the staff.
[0037] When the installed engine frame needs to be flipped during the assembly process, the fixed shell 12 is pushed to separate the fixed shell 12 from the gear ring 11, and the fixed shell 12 drives the pushing seat 14 to move along the limiting rod 13, and the first spring 15 is compressed. At this time, the turning handle 17 is turned, and the turning handle 17 drives the flip shaft 8 to rotate, and the flip shaft 8 drives the mounting plate 9 and the engine frame to rotate, so as to flip the engine frame. The rotation of the flip shaft 8 will also drive the gear ring 11 to rotate. When the flipping is completed, the fixed shell 12 is released, and under the action of the first spring 15, the fixed shell 12 is sleeved on the outside of the gear ring 11 to fix the gear ring 11, and the limiting plate 16 limits it, so that the engine frame can be fixed by the flip shaft 8 and the mounting plate 9.
[0038] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
