[0002] During the maintenance process of mechanical equipment, the disassembly and assembly of sprockets, couplings, torque limiters, couplings, and gears are the most common maintenance items. Currently, a 300T hydraulic stretcher is usually used for disassembly. However, due to the relatively large three-jaw gripper of the hydraulic stretcher, when disassembling equipment such as sprockets, it is impossible to directly disassemble due to the small gap at the disassembled part. Each disassembly requires welding a positioning tooling on the body of the equipment to be disassembled. This not only makes the process troublesome but also causes an eccentric phenomenon between the disassembled equipment and the hydraulic cylinder when the positioning tooling is welded non-coaxially, resulting in damage to the disassembled equipment during the disassembly process. In severe cases, the parts may be directly scrapped, and there is an urgent need for improvement. Content of the Utility Model:

[0003] The purpose of the utility model is to provide a multifunctional disassembly and assembly device to solve the technical problems of difficult disassembly and assembly of sprockets, time-consuming and laborious disassembly and assembly, and easy damage to parts in the prior art.

[0006] Further, sliding through grooves are opened on the inner walls at both ends of the power chamber, and the connecting rod and the piston rod of the hydraulic cylinder are respectively slidably connected up and down with the sliding through grooves, and the piston rod of the hydraulic cylinder extends into the disassembly and assembly chamber.

[0007] Further, a plurality of triangular gusset plates are horizontally welded in the equipment box body, and the gusset plates are located at the corners of the equipment box body.

[0008] Further, a mesh cover plate is fixedly installed at the top of the disassembly and assembly chamber.

[0010] Further, the limiting plate is fixedly installed on the cross beam, and U-shaped slots are installed at both ends of the cross beam, and the slots are inserted into the equipment box body.

[0011] The beneficial effects of the present utility model: The structure of the present utility model is simple, and a box-type disassembly and assembly device is designed. The V-shaped positioning through groove is used for radial positioning of sprockets, etc., which can adapt to the disassembly and assembly of sprockets with different diameters.

[0016] Embodiment 1:

[0017] As Figure 1 and 3 shown, a multifunctional disassembly and assembly device includes an equipment box body 1 with an open top. A partition board 2 is vertically installed in the equipment box body 1. The partition board 2 divides the inner cavity of the equipment box body 1 into a power cavity and a disassembly and assembly cavity. A hydraulic cylinder 5 is slidably connected up and down in the power cavity. A height adjustment component is installed on the hydraulic cylinder 5. A V-shaped positioning through groove 4 is opened on the equipment box body 1, and the positioning through groove 4 is communicated with the disassembly and assembly cavity.

[0018] As Figure 3 shown, the height adjustment component includes a buckle 6. The buckle 6 is fixedly installed on the hydraulic cylinder 5. A screw rod 7 is rotatably connected to the buckle 6. The screw rod 7 is screwed to a sealing cover 3. The sealing cover 3 is fixedly installed on the equipment box body 1. Sliding through grooves 10 are opened on the inner walls at both ends of the power cavity. The connecting rod of the hydraulic cylinder 5 and the piston rod of the hydraulic cylinder 5 are respectively slidably connected up and down with the sliding through grooves 10. The piston rod of the hydraulic cylinder 5 extends into the disassembly and assembly cavity.

[0019] In order to improve the strength of the equipment box body 1, as Figure 2and Figure 3 As shown, several triangular gusset plates 11 are horizontally welded inside the equipment box body 1, and the gusset plates 11 are located at the corners of the equipment box body 1; for facilitating the observation of the operation condition, such as Figure 1 As shown, a mesh cover plate 13 is fixedly installed at the top end of the disassembly and assembly cavity.

[0020] When performing the sprocket wheel pulling operation, place the sprocket shaft on the positioning through groove 4 for radial positioning, and make the sprocket wheel located in the disassembly and assembly cavity. Then adjust the height adjustment assembly to make the hydraulic cylinder 5 basically coaxial with the sprocket wheel. Start the hydraulic cylinder 5 to extend the piston rod to push out the sprocket shaft, while the sprocket wheel remains in the disassembly and assembly cavity, thus completing the disassembly; when installing the wheel, use the same operation. First, pre-install the sprocket shaft, and then use the hydraulic cylinder 5 to push the sprocket shaft into the sprocket wheel to complete the installation.
