Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Combine the following Figure 1 to Figure 2 A sleeve assembly device provided in an embodiment of the utility model is described.

[0028] The present embodiment provides a casing assembly device, which includes: a pit, a workpiece lifting platform 1 , a casing fixing structure 11 and an operation lifting platform 2 .

[0029] Among them, the workpiece lifting platform 1 is arranged in the pit, and the workpiece lifting platform 1 can move along the height direction of the pit; the sleeve fixing structure 11 is arranged on the workpiece lifting platform 1, which can be a fixed rod, a fixed pin or a fixed shaft or other structures. By sleeve-mounting the bottom of the sleeve on the sleeve fixing structure 11, the bottom of the sleeve is fixed on the workpiece lifting platform 1; the working lifting platform 2 is arranged in the pit, and the working lifting platform 2 can carry the staff and move along the height direction of the pit. The working lifting platform 2 is located above the workpiece lifting platform 1, and the working lifting platform 2 is provided with a working opening for the sleeve to pass through.

The closing mechanism may include multiple bearing plates, which are evenly distributed around the casing, and the multiple bearing plates are driven by multiple driving devices respectively. One side of the bearing plate corresponding to the casing may be arc-shaped, and the multiple bearing plates are moved toward the center of the working opening to change the size of the working opening and clamp the casing.

[0033] With such an arrangement, the diameter of the working opening is adjusted through the closing mechanism so that the working opening is adapted to the outer diameter of the casing to accommodate casings of different diameters, thereby facilitating the fixing of the casing in the working opening to prevent shaking. It is also convenient for workers to work close to the casing to avoid accidents of workers accidentally falling from the working opening, thereby improving safety.

[0034] In this embodiment, a pressing device 3 is also included. The pressing device 3 is arranged on the ground and is used to press the top of the casing. Figure 1 As shown, the clamping device 3 is a flip-type press machine, including a first column 31, a second column 32 and a flip frame 33. The first column 31 and the second column 32 are supported on the ground on both sides of the pit opening respectively. A clamping mechanism is arranged on the flip frame 33, and the clamping mechanism faces the pit opening. The top of the first column 31 is hinged with the flip frame 33. A cylinder, an electric cylinder or a hydraulic cylinder is arranged on the first column 31 or the ground. For example, the driving end of the hydraulic cylinder is connected to the first end of the flip frame 33. The second end of the flip frame 33 is a free end. The flip frame 33 is driven by the hydraulic cylinder to flip around the hinge point, and the clamping device 3 is opened to facilitate the installation of the casing into the pit. In addition, the top of the second column 32 is used to support the second end of the flip frame 33. A locking mechanism can be arranged on the top of the second column 32 to connect the second end of the flip frame 33 with the second column 32, so as to facilitate the clamping operation on the top of the casing.

[0035] When the utility model is used for the assembly of the sleeve, first the workers on the ground complete the assembly of the base, the lower porcelain part and the core of the sleeve, then put the sleeve into the pit through the lifting equipment, and insert the bottom of the sleeve on the sleeve fixing structure 11, adjust the height of the workpiece lifting platform 1 in the pit, manually enter the working lifting platform 2 through the ladder 7, and then control the working lifting platform 2 to stop at a suitable position, the closing mechanism narrows the working opening to clamp the sleeve, and the workers approach the sleeve to perform the assembly operation. At the same time, the sleeve on the ground is manually installed with an oil collecting box, a spring and a spring pressure plate, and the spring is automatically pressed and installed using the clamping device 3, and finally the special nut is manually installed to complete the assembly of the sleeve.
