[0023] The markings in the figure are as follows: 1-arc back plate 1, 2-long tapered pin 2, 3-push-type locking pin 3, 4-handle 4, 5-control button 5, 6-hanger flange connection surface 6.

[0024] Among them, 1 is an arc-shaped back plate, 2 is a long tapered pin, 3 is a push-type locking pin, 4 is a handle, 5 is a control button, 6 is a sling flange connection surface, 7 is a connecting plate, 10 is a sling, 11 is a back plate, 12 is a left top plate, 13 is an inverted L-shaped plate, 14 is a right top plate, 15 is a middle top plate, 20 is an end cover, and 21 is a small through hole. Specific implementation method:

[0025] A certain end cover is hemispherical and needs to be installed on the butt joint surface of the barrel end. The total weight of the end cover is 65kg, and there are 12 evenly distributed bolt connection holes with a diameter of 13mm and a positioning pin hole with a diameter of 8.1mm on the outer edge; a sealing ring needs to be installed on the contact surface between the end cover and the side of the barrel end. The assembly surface of the end cover is not allowed to be scratched. The end cover surface and the outer side of the outer edge are painted and are not allowed to be scratched. The end cover is transported through special tooling, and the butt joint surface is in a vertical state when the assembly is completed, and the corresponding bolt connection hole is in the highest position. The traditional installation process requires two skilled operators to work together to lift the end cover to a height of 1.5 meters from the ground, and then flip it, position it with the positioning pins, and complete 12 sets of bolt connections. This occupies too many human resources in the production process of the overall product, limiting the further increase of production capacity. The present invention provides a special clamp for the transportation and assembly of end covers. The device realizes the positioning and lifting of the end cover through a long tapered pin 2. The long tapered pin 2 passes through the bolt connection hole on the outer edge of the end cover, and the workpiece is locked and loosened by a push-type locking pin 3, thereby realizing the transportation of the end cover. The whole process can be completed by one person, and the device has strong practicality and good promotion.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1As shown, a special clamp for carrying end caps of the present invention is used in conjunction with a rigid intelligent lifting device to achieve the lifting, lifting and transportation of hemispherical end caps. The clamp material is made of cemented carbide and is manufactured using an electric spark process to ensure that the overall structure will not deform when bearing weight. The main structure of the clamp includes an arc-shaped back plate 1, a long taper pin 2, a push-type locking pin 3, a handle 4, a control button 5, and a flange connection surface 6 of the sling. The characteristics are as follows: the arc-shaped back plate 1 of the clamp fits tightly with the outer edge of the end cover, and the surface of the back plate is attached with hard plastic to protect the assembly surface of the end cover and prevent scratches; the long taper pin 2 is used to pass through the bolt connection hole on the outer edge, and the pin length is 150mm, ensuring that it completely passes through the outer edge of the end cover with a thickness of 25mm and the outer edge of the end cover assembly body with a thickness of 50mm; there is a push-type locking pin 3 on the clamp, which can lock the end cover after lifting to prevent it from falling off; the clamp is integrated with a handle 4, which is convenient for operators to grasp and drag with the rigid intelligent balancing sling; the handle 4 is integrated with a control button 5, which is used to switch the working mode of the intelligent balancing sling. The human hand relies on the sliding between the taper pin and the bolt connection hole of the end cover to push the end cover to the butt joint surface of the barrel end, thereby completing the bolt connection and realizing the fastening assembly.

[0028] 1. A clamp for lifting and installing large diameter end caps, the main features of which are:

[0029] (1) The fixture and the rigid balance hoist are coordinated so that the end cover presents a vertical assembly end surface after hoisting. During the transportation process, the fixture only requires three translational degrees of freedom and yaw rotational degrees of freedom in space, and does not require roll and pitch degrees of freedom;

[0030] (2) Installed on the flange end face of the rigid intelligent balancing sling, it is integrated with a button that can adjust the working mode of the balancing sling, which can realize power lifting and end cover installation when operated by one person;

[0031] (3) The fixture uses a specially made long tapered pin 2 to lift the end cover. There are 12 bolt connection holes on the outer edge of the end cover to be transported, which correspond to the threaded holes on the assembly surface of the barrel end. The long tapered pin 2 passes through a bolt connection hole on the outer edge of the end cover. The state of the end cover after lifting is the state when the assembly is completed. The long tapered pin 2 has a diameter of 10mm and can easily pass through the bolt connection hole with a diameter of 13mm on the outer edge of the end cover; the tapered pin is 150mm long to ensure that it can completely pass through the outer edge of the end cover with a thickness of 25mm and the outer edge of the end cover assembly body with a thickness of 50mm. After it is completely passed through, a locking pin can be installed to ensure that the end cover will not fall off;

[0032] (4) A locking pin is installed at the end of the long tapered pin 2. When the fixture completes the clamping of the end cover, the locking pin is manually pressed to lock it, which can prevent the end cover from falling off. When performing the end cover assembly operation, after the end of the tapered pin passes through the bolt connection hole of the assembly surface, the locking pin is manually released, so that the end cover and the assembly surface can be completely fitted together, which is convenient for subsequent bolt connection.

[0033] 2. The main structure of the fixture includes the following parts: an arc-shaped back plate 1 that fits the outer edge of the end cover, a flange connected to the rigid balance crane, a long taper pin 2 that passes through the bolt connection hole of the end cover, a push-type locking pin 3, a control button 5, and a handle 4. The arc-shaped back plate 1 and the long taper pin 2 are the main structure of the fixture. They are made of a whole piece of hard alloy steel and are formed by electric spark machining to ensure the rigidity of the overall structure and prevent deformation during the lifting process, thereby ensuring the stability of the posture of the end cover during transportation; there is a small through hole on the cylindrical surface of the long taper pin 2. After the end cover is clamped in place, press the The push-type locking pin, the pin of the locking pin is stuck in the through hole of the long cone pin 2, so as to ensure that the end cover will not fall off during transportation; when the end cover is fitted with the outer edge of the assembly, the long cone pin 2 is manually operated with the rigid balance crane to pass through the corresponding bolt connection hole on the outer edge of the assembly. At this time, the locking pin is released to push the end cover and the outer edge of the assembly to fit together, and other bolt connections except the connection hole through which the long cone pin 2 passes are completed to ensure the fastening of the end cover and the assembly. The clamp is manually removed, and the long cone pin 2 is pulled out of the connection hole to complete the bolt connection of the hole position, that is, the assembly of the end cover is completed. The main structure is fastened with the flange, handle 4, control button 5 unit, etc. through bolt connection. The handle 4 can facilitate the operator to cooperate with the rigid intelligent lifting device to operate, and the working mode of the intelligent lifting device can be adjusted through the control button 5.

[0034] 3. The end cover can be hoisted and transported with the help of rigid intelligent lifting equipment. The long taper pin 2 is passed through the bolt connection hole on the outer edge of the end cover to achieve hoisting. The overall rigidity of the equipment enables the end cover to always maintain a basic vertical state during transportation and assembly.

[0035] The present invention provides a special fixture for lifting, transporting and assembling a hemispherical end cap. The fixture is made of carbide material and processed by electric spark machining. The part that fits the end cap connection hole is surface treated to prevent deformation. Finite element analysis shows that the safety factor meets the requirements. The main structure of the fixture is a long taper pin 2, the bottom diameter of the taper pin is 10 mm, the top diameter is 8 mm, and the total length is 100 mm. It can easily pass through the bolt connection hole on the outer edge of the end cap, and the end cap can be in a vertical state with the rigid intelligent sling. There is a push-type locking mechanism on the top of the taper pin, which can be pressed and locked after the end cap is lifted, and the operation is simple and fast. There is a handle for the operator to hold on the fixture, and the control button 5 of the rigid intelligent sling is integrated on the handle, which can realize the switching of the sling between the no-load and loaded states, and facilitate the docking with the assembly surface and the connection of the bolts. The fixture can be integrated in the digital assembly production line, only requires single-person operation, fast response capability, strong practicality, and good promotion.
