[0041] A fixing plate 134, which is disposed at the lower end of the telescopic cylinder 132, and a telescopic rod 133 passes through the fixing plate 134 and is located below the fixing plate 134;

[0042] A support plate 14, which is arranged at the lower end of the telescopic rod 133; mounting grooves 141 are provided on both sides of the support plate 14; a rotating column 142 is rotatably connected in the mounting groove 141; driving grooves 143 are provided on both sides of the support plate 14, the driving grooves 143 are located on both sides of the mounting groove 141, and both ends of the rotating column 142 extend into the driving grooves 143 on both sides;

[0043] The outer side of each rotating column 142 is rotatably connected with a plurality of gear rings 144, and the plurality of gear rings 144 are all located inside the corresponding mounting groove 141; a driving ring 145 is arranged inside each driving groove 143, and the shape of the driving ring 145 is the same as that of the gear ring 144; an L-shaped clamping block 146 is fixedly connected to the outer side of each gear ring 144, and in an initial state, the plurality of clamping blocks 146 are in an overlapping state; a clamping strip 147 is detachably installed between the two driving rings 145, and in an initial state, the clamping strip 147 is embedded in the tooth groove on the driving ring 145; the clamping strip 147 is located between the two driving rings 145 and is embedded in the tooth groove on each gear ring 144;

[0044] A driving plate 148 is fixedly connected to the inner side of each driving ring 145. In the initial state, the driving plate 148 is parallel to the supporting plate 14. A first hinge rod 135 is hinged at each of the four corners of the fixed plate 134. The lower end of the first hinge rod 135 is rotatably connected to one end of the corresponding driving plate 148 away from the driving ring 145.

[0045] The support plate 14 is composed of two slide plates 15 and a connecting plate 16, and the upper end of the connecting plate 16 is connected to the lower end of the telescopic rod 133;

[0046] The two slide plates 15 are slidably connected to the two sides of the connecting plate 16 respectively;

[0047] The specific workflow is as follows;

[0048] When assembling the cylinder block in the engine, the staff can control the rotating plate 11 to move at the upper end of the hanging frame body 1. During the movement of the rotating plate 11, the winder 12 at the upper end of the rotating plate 11 moves synchronously with it. During the process, the cable 13, the mounting block 131, the telescopic cylinder 132, the telescopic rod 133, the fixed plate 134 and the supporting plate 14 at the lower end of the winder 12 move synchronously until the fixed plate 134 and the supporting plate 14 move to the upper end of the cylinder block. At this time, the staff controls the rotating plate 11 to stop rotating. The power source for the rotating plate 11 to rotate is the motor arranged on the rotating plate 11.

[0049] When the support plate 14 and the fixing plate 134 move to the upper end of the cylinder body, the staff controls the winder 12 to unwind, and the cable 13 wound inside the unwinder is unwound, so that the mounting block 131, the fixing plate 134 and the support plate 14 move downward; in the process of the support plate 14 moving downward, until the upper end of the support plate 14 contacts the cylinder mouth at the upper end of the cylinder body, the support plate 14 remains stationary at the upper end of the cylinder body; the L-shaped block 146 is located at the edges on both sides of the cylinder body; at this time, the telescopic rod 133 inside the telescopic cylinder 132 is extended, and the specific action is that the support plate 14 remains stationary, the fixing plate 134 moves upward, and the fixing plate 134 moves upward. The gap between the fixed plate 134 and the support plate 14 becomes larger; during this process, the first hinge rod 135 will pull the driving plate 148, and the end of the driving plate 148 away from the driving ring 145 will be pulled by the first hinge plate, and the driving plate 148 will rotate, which is specifically manifested in that the driving plate 148 and the first hinge plate tend to be parallel to each other; during this process, the driving plate 148 will drive the driving ring 145, so that the driving ring 145 rotates; because the tooth grooves on the two driving rings 145 are embedded with the clamping strip 147, and the middle part of the clamping strip 147 is embedded in the tooth groove on the gear ring 144 sleeved on the middle outer side of the rotating column 142, when the driving plate 1 During the rotation of the gear ring 144, the driving plate 148 drives the driving ring 145 to rotate, and the driving ring 145 drives the rotating column 142 to rotate during the rotation. In addition, since the two driving rings 145 drive the clamping strip 147 to rotate during the rotation, and the middle part of the clamping strip 147 is embedded in the tooth groove of the gear ring 144, the driving ring 145 drives the gear ring 144 to rotate through the rack. During the rotation of the gear ring 144, the clamping block 146 is driven to rotate, and the lower end of the clamping block 146 rotates toward the side edge of the cylinder on the cylinder body until the bent section at the lower end of the clamping block 146 is embedded in the lower end of the edge of the cylinder body. At this time, the telescopic cylinder 132 and the The telescopic rods 133 stop extending, and the distance between the support plate 14 and the fixed plate 134 remains unchanged. The cooperation between the telescopic cylinder 132 and the telescopic rod 133 is a hydraulic telescopic cylinder 132 structure; then the winder 12 is wound, the winder 12 winds up the cable 13, the cable 13 pulls the mounting block 131, the mounting block 131 drives the telescopic cylinder 132, the fixed plate 134 and the support plate 14 to move upward, and the support plate 14 drives the cylinder body to move upward through the clamping block 146; the cylinder body is lifted, and then the working rotation controls the rotating plate 11 to rotate, and the rotating plate 11 brings the cylinder body to the position where it needs to be installed, and the cylinder body is installed;

[0050] In the above process, if it is necessary to replace a cylinder body of a different model, the staff will remove the card strip 147 from the gear ring 144 and the drive ring 145. After removing it, the staff will move the support plate 14 to the upper end of the replaced cylinder body, and then increase the gap between the fixed plate 134 and the support plate 14. During the process, the drive plate 148 drives the drive ring 145 to rotate, the drive ring 145 drives the rotating column 142 to rotate, and the rotating column 142 drives the gear ring 144 to rotate. At this time, there is no limit between the gear ring 144 and the rotating column 142; if there is a connecting block or a supporting block between the cylinders on the replaced cylinder body; at this time, the connecting card block 146 or the support block will block the card block 146 that contacts it. , the blocked block 146 rotates on the rotating column 142, so that the blocked block 146 does not enter under the edge of the cylinder body, while the unblocked block 146 enters under the edge of the replaced cylinder body; then, keeping this state, the staff reinstalls the clamping strip 147 in the tooth grooves on the drive ring 145 and the gear ring 144, so that the clamping strip 147 limits the drive ring 145; and synchronously limits the non-rotating gear ring 144 and the rotating gear ring 144; so that the gear ring 144 is driven again during the rotation of the drive ring 145; thereby achieving the ability to clamp and install cylinder bodies of different sizes and models; improving the assembly efficiency of the cylinder body;

[0051] The support plate 14 is composed of two slides 15 and a connecting plate 16, and the two slides 15 are respectively slidably connected on both sides of the connecting plate 16, so that when a cylinder body with a larger width is clamped, the staff adjusts the two slides 15, and the two slides 15 slide from the connecting plate 16 into the groove 163. During this process, the distance between the block 146 on the two slides 15 and the driving plate 148 becomes larger, and the angle between the No. 1 hinge rod 135 and the driving plate 148 becomes larger, so that the No. 1 hinge rod 135 can adapt to the size changes of the two slides 15; thereby, the cylinder bodies of different widths can be clamped and assembled.

[0052] Embodiment 2:

[0053] like Figures 2 to 9 As shown; a plurality of No. 1 columns 161 are evenly arranged at the lower end of the connecting plate 16, a No. 2 column 162 is arranged at the lower end of each No. 1 column 161, a slide groove 163 is provided at the lower end of the No. 1 column 161, and the No. 2 column 162 is slidably connected inside the slide groove 163, and a No. 3 column 164 is arranged at the lower end of the No. 1 column 161; a plurality of No. 2 hinged rods 165 are evenly arranged at the lower end of the No. 1 column 161, and a plurality of No. 3 hinged rods 166 are evenly arranged at the upper end of the No. 3 column 164, and the number of the No. 3 hinged rods 166 is the same as the number of the No. 2 hinged rods 165;

[0054] Each of the second hinged rods 165 and the first hinged rod 135 is hinged together at a section close to each other through a hinged column 167; the outer side of each of the second hinged rods 165 and the first hinged rod 135 is paved with a rubber layer;

[0055] The specific workflow is as follows;

[0056] A No. 1 column 161 is provided at the lower end of the connecting plate 16, and a No. 2 column 162 is provided at the lower end of each No. 1 column 161, and the No. 2 column 162 is slidably connected to the inside of a slide groove 163 opened at the lower end of the No. 1 column 161; and the No. 2 column 162 is slidably connected to the inside of the slide groove 163 at the lower end of the No. 1 column 161 through a sliding connection of the electric telescopic rod 133; when the cylinder body is lifted, the support plate 14 contacts the upper end of the cylinder body, and the No. 1 column 161, the No. 2 column 162 and the No. 3 column 164 enter the cylinder on the cylinder body, and then the electric telescopic rod 133 in the slide groove 163 contracts, and at this time the No. 2 column 162 slides into the No. 1 column 161, and the No. 2 column 162 drives the No. 3 column 164 to approach the direction of the No. 1 column 161, and the distance between the No. 3 column 164 and the No. 1 column 161 The gap becomes smaller, and the second hinge plate and the third hinge plate arranged between the third column 164 and the first column 161 rotate; the specific rotation action is: the angle between the first hinge plate and the second hinge plate gradually becomes smaller, and at the same time, the hinge column 167 is pushed away from the second column 162, so that the rubber layer on the outside of the first hinge rod 135 and the second hinge rod 165 squeezes the inner wall of the cylinder on the cylinder body, and when the outer wall of the second hinge rod 165 and the third hinge rod 166 squeezes the outer wall of the cylinder on the cylinder body, the electric telescopic rod 133 in the slide groove 163 stops working and maintains the current state; when the cylinder body is lifted, the rubber layer on the outside of the second hinge rod 165 and the third hinge rod 166 squeezes the inner wall of the cylinder of the cylinder body, thereby increasing the efficiency of lifting the cylinder body.

[0062] The arc plate 168 is an elastic plate, and the material of the arc plate 168 is an arc steel plate. When the first column 161, the second column 162 and the third column 164 enter the interior of the cylinder on the cylinder body, the arc plate 168 does not contact the interior of the cylinder on the cylinder body until the arc plate 168 moves away from the second column 162, and then the arc plate 168 contacts the inner wall of the cylinder on the cylinder body. During the process, if the diameter of the cylinder on the cylinder body is small, the arc plate 168 will undergo elastic deformation, so that the arc plate 168 can adapt to the cylinder on the small-sized cylinder body; thereby improving the lifting effect of the cylinder body, and thereby improving the assembly efficiency of the cylinder body.

[0067] The specific workflow is as follows;

[0068] By arranging a driving motor 17 at the upper end of the No. 1 column 161, the output shaft of the driving motor 17 is connected to the upper end of the No. 1 column 161; on the basis of the above-mentioned embodiment 3, after the cylinder body is lifted, the cylinder body is then moved to the position where it needs to be assembled, and then the clamping block 146 is no longer hooked on the edge of the cylinder body, and then the driving motor 17 is started, and the driving motor 17 drives the No. 1 column 161 to rotate, and the No. 1 column 161 drives the No. 2 column 162, the No. 3 column 164, the No. 2 hinge rod 165 and the No. 3 hinge rod 166 to rotate; during the process, when the hinge column 167 drives the arc plate 168 to rotate, the arc During the rotation of the plate 168, the inner wall of the cylinder on the cylinder body is scraped; and as the winder 12 shrinks upward, the fixed plate 134 and the support plate 14 move upward synchronously, so that the second column 162, the third column 164 and the first column 161 move upward, and the arc plate 168 moves upward synchronously, so that the arc plate 168 cleans the inner wall of the cylinder from the inside to the outside on the cylinder, avoiding the problem of processing residues inside the cylinder body; when the arc plate 168 moves to the inside of the cylinder on the cylinder body, the electric telescopic rod 133 inside the slide 163 extends, and the second hinge rod 165 and the third hinge rod 166 are reset;

[0069] The upper end of the drive motor 17 is slidably connected to the lower end of the connecting plate 16, and the drive motor 17 can only be slidably connected left and right at the lower end of the connecting plate 16 and cannot rotate; and the drive motor 17, column 161, column 2, column 162 and column 3 can be disassembled from the lower end of the connecting plate 16; after replacing the cylinder body, if the distance between the cylinders on the cylinder body changes, it is only necessary to move the drive motor 17 at the lower end of the connecting plate 16 to adapt to the distance between the cylinders on the replaced cylinder body; if there are fewer or more cylinders on the replaced cylinder body, the redundant drive motor 17 is immediately disassembled at the lower end of the connecting plate 16, and if there are more cylinders on the cylinder body, it is only necessary to install the missing drive motor 17, column 161, column 2, column 162 and column 3, thereby improving the applicability to different cylinder bodies and improving the assembly efficiency of the cylinder body.
