Description

Technical Field

[0001] The invention belongs to the technical field of machinery, and in particular relates to a motor disassembly and assembly tool for post-processing tail-end special equipment. Background Art

[0002] In the field of spent fuel reprocessing, the most important process of the P-end hot cell line is the circulation and transportation of products. The core equipment of this process is the hot cell line conveyor, which is used to complete the transfer of filter cups between hot cells. Its channel is a high-dose closed and narrow space. The hot cell line conveyor is installed in the lower box of the hot cell. When it runs horizontally to each hot cell station, it relies on the built-in motor to drive the hollow turntable, drive the lead screw nut, complete the lifting of the platform, and realize the transfer of products. However, the motor is a consumable part, and the replacement of the motor will be involved in the equipment maintenance process.

[0003] Since the tail-end process path in the post-processing field requires the use of a hot chamber line conveyor to participate in the transportation links such as cleaning the hot chamber, filtering the hot chamber, roasting the hot chamber, and unloading the hot chamber, when the production line is officially put into operation, if a failure occurs, it is necessary to arrange for inspection and maintenance staff to be replaced at irregular intervals. Because the lifting motor of the hot cell line conveyor is installed in the maintenance channel of the lower box of the hot cell, and the installation location is a highly radioactive place, the inspection and maintenance personnel need to wear full-body gas suits throughout the entire process when entering the area for inspection and maintenance work. However, the inspection channel is a closed and narrow space. When inspecting the built-in motor of the hot cell line conveyor in the early stage, the inspection cover of the inspection channel needs to be removed first. It was found that the motor and the commutator were connected with a plum blossom coupling, and the motor was installed and fixed to the bottom of the trolley with 4 sets of hexagonal bolts. The height distance of the bolts at the bottom of the trolley from the inspection window is about 300mm, and the length distance is about 430mm. In addition, the installed motor, motor power and encoder connector, cable, coupling, hollow turntable, and installation position are too close. The manufacturer has design defects in the layout of the motor position and has not considered the convenience of inspection and maintenance in radioactive places.

[0004] If a fault occurs, the maintenance personnel need to use the corresponding type of hexagon socket tools to repair or replace the motor. Due to the limitation of wearing air suits and the confined and narrow space, the maintenance personnel's arms interfere with other parts of the motor, making it impossible to remove the built-in motor, or the motor removal process takes a long time, is inefficient, and the personnel are exposed to a high dose of radiation. The corresponding type of hexagon socket length in the existing technology is much less than 440mm. When replacing the motor, the maintenance personnel are also unable to determine whether the hexagon socket bolts are firmly connected. If there is a gap at the connection, the bolts are prone to loosening after the motor has been running for a long time, causing the motor to shake, which may cause the hot chamber line conveyor to have a major fault again.

[0005] When the inspection and maintenance personnel simulated radioactive conditions and wore full-body gas suits to inspect the built-in motor of the hot cell line conveyor, it was extremely difficult to remove the hexagon socket bolts fixed on the bottom of the motor box with a handheld hexagonal tool due to the gas suit and limited space. They had to stay in a highly radioactive place for a long time. There was also the possibility that the tools would fall into the inside of the motor box during disassembly, making the inspection and maintenance unreachable.

[0006] By searching relevant domestic and foreign literature, it is found that there is no multifunctional tool designed for the rapid disassembly and assembly of rotating motors in confined and narrow spaces, which does not meet the needs of the diversity and complex working conditions of tail-end special equipment in the domestic post-processing field. It is necessary to design a tool for high-radioactive places that can quickly disassemble and assemble horizontal motors in most confined spaces. Summary of the invention

[0007] The technical problem solved by the present invention is: to provide a motor disassembly and assembly tool for post-processing tail-end special equipment, which can be used for rapid disassembly and assembly by inspection and maintenance personnel, avoiding the personnel from putting their arms into the box to disassemble and assemble the motor. While ensuring the inspection and maintenance efficiency of the inspection and maintenance personnel, it also shortens the inspection and maintenance time, reduces the work intensity of the personnel, and significantly improves work efficiency.

[0008] The technical solution adopted by the present invention is:

[0009] A tool for disassembling and assembling motors of post-processing tail-end special equipment, comprising a connecting seat, a motor connecting seat, a reducer plum blossom coupling, and a motor plum blossom coupling. The connecting seat is used to cooperate with the reducer, and the motor connecting seat is used to cooperate with the motor. The connecting seat is a square structure with a central through hole on the front end surface. One end of the reducer plum blossom coupling is a stepped shaft mechanism, and the other end is a plum blossom connection structure. The stepped shaft is inserted into the through hole and limited by the through hole, and the front end of the stepped shaft is connected to the reducer; the motor connecting seat is a T-shaped structure with a through hole in the center. One end of the motor plum blossom coupling is a plum blossom connection structure, and the other end is connected to the motor output shaft inserted into the through hole, and the two plum blossom connection structures are connected in a cooperative manner.

[0010] A boss is provided on the front end surface corresponding to the through hole on the front end surface of the connection seat, and the boss is used to correspond to the position of the reducer.

[0011] The four corners of the front end surface are respectively provided with threaded holes, and after the connecting seat and the reducer are butt-jointed, they are connected via hexagonal threads.

[0012] The upper and lower side walls of the connection seat are provided with grooves, and the motor connection seat is provided with through grooves at corresponding positions. After the connection seat and the motor connection seat are docked, the fixed guide plate falls into the groove, and the connection seat and the motor connection seat are fixedly connected by screws.

[0013] It also includes a locking mechanism, which includes a locking handle, a locking block, and a locking shaft. The locking shaft is a stepped shaft structure, one end of the locking shaft is connected to the locking handle, and the other end of the locking shaft is locked by the locking block.

[0014] Through holes are formed on both sides of the upper end of the motor connection seat, and one end of the locking shaft passes through the through hole and is connected to a locking handle.

[0015] A washer is provided at the front end of the locking handle.

[0016] The connection seat and the locking block are provided with grooves at positions corresponding to the positions. When the locking handle is rotated, the locking shaft is driven to rotate, so that the locking block is connected with the groove of the connection seat after rotation, thereby ensuring that the connection seat is connected with the motor connection seat.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 and Figure 2As shown, the present invention provides a motor disassembly and assembly tool for post-processing tail-end special equipment, including a connecting seat 1, a motor connecting seat 2, a reducer plum blossom coupling 3, a motor plum blossom coupling 4, a locking handle 6, a locking block 7, and a locking shaft 8. The connecting seat 1 is used to cooperate with the reducer for connection, and the motor connecting seat 2 is used to cooperate with the motor for connection. The connecting seat 1 is a square structure, and a central through hole is opened on the front end surface. A boss is provided on the front end surface corresponding to the through hole, and the boss is used to correspond to the position of the reducer. Threaded holes are respectively opened at the four corners of the front end surface. After the connecting seat 1 is docked with the reducer, it is connected through a hexagonal inner thread; one end of the reducer plum blossom coupling 3 is a stepped shaft mechanism, and the other end is a plum blossom connection structure. The stepped shaft is inserted into the through hole and limited by the through hole, and the front end of the stepped shaft is connected to the reducer; the motor connecting seat 2 It is a T-shaped structure with a through hole in the center. One end of the motor plum blossom coupling 4 is a plum blossom connection structure, and the other end is inserted into the through hole and connected to the motor output shaft, and the two plum blossom connection structures are matched and connected; the upper and lower side walls of the connecting seat 1 are provided with grooves, and the motor connecting seat 2 is provided with through grooves at corresponding positions. After the connecting seat 1 and the motor connecting seat 2 are docked, the fixed guide plate 5 falls into the groove, and the connecting seat 1 and the motor connecting seat 2 are fixedly connected by screws; the locking shaft 8 is a stepped shaft structure, and through holes are provided on both sides of the upper end of the motor connecting seat 2. One end of the locking shaft 8 is connected to a locking handle 6 after passing through the through hole, and a washer 9 is provided at the front end of the locking handle 6; the other end of the locking shaft 8 is locked by a locking block 7; grooves are provided at the corresponding positions of the connecting seat 1 and the locking block 7 to facilitate the rotation of the locking block 7 without interference.

[0029] The working principle of the present invention is:

[0030] When disassembling the motor, rotate the locking handle 6 upward to ensure that the ends of the locking shafts 8 on both sides are rotated outward, and the locking handles 6 on both sides are in a vertical state. Separate the motor and the reducer from each other, and the built-in motor can be removed by simply dragging the motor backwards.

[0031] When reinstalling, the motor and the reducer are first aligned according to the thread of the plum blossom coupling. After the alignment is completed, the locking handle 6 is turned. When the locking handle is turned 6 to a parallel state, the internal locking shaft mechanism 8 locks the motor and the reducer.

[0032] Combined with the on-site environment and usage requirements of the hot chamber, alloy materials with higher tensile strength are used instead of ordinary carbon steel and aluminum for prefabrication to prevent rust or oxidation crystals on the tool surface due to the working environment. The connecting seat 1 is consistent with the size of the coupling and is used to install the coupling on the connecting seat. One end of the locking shaft 8 is designed to be an angular quadrilateral for connection with the locking handle 6. The locking handle 6 is designed to rotate in two directions, left and right, in order to facilitate the disassembly and reinstallation of the motor. When disassembling the motor, you only need to turn the locking handle 6. Since the locking handle 6 is fixedly connected to the locking shaft 8, the locking shaft 8 will rotate a certain angle, thereby realizing the separation of the motor and the reducer.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
