Description

Technical Field

[0001] The utility model relates to the technical field of sleeve tools, in particular to a sleeve tool for subway vehicle maintenance. Background Art

[0002] When a subway vehicle is overhauled, it is necessary to inspect and repair the brake system components, and normal debugging is required after the inspection is completed and the vehicle is loaded. During the debugging process, the valve pressure design value needs to be reset. Among them, when the empty weight valve adjusts the pressure under the vehicle, it is not restricted by space, and the debugging pressure setting is relatively convenient. At present, the empty weight valve setting value adjustment tool of the brake system is a common tool on the market. When the empty weight valve setting value is adjusted, it is adjusted by using a wrench, but the wrench is too long and cannot be operated at a normal operating angle, resulting in it slipping out of the hand during operation. For this purpose, the application number: 202120266803.7 discloses a sleeve tool for subway vehicle maintenance, including an upper and lower detachable part The sleeve body is divided into two parts, the upper part is a sleeve connector, the lower part is a sleeve body, the sleeve connector and the sleeve body are connected through a hexagonal mating surface, the sleeve connector drives the sleeve body to rotate, the upper part of the sleeve connector is a ratchet wrench interface, the lower part is a second inner hexagonal hole, the upper part of the sleeve body is an outer hexagonal connector, the inside of the sleeve body is processed from top to bottom into a section of circular hole, the lower part of the sleeve body is a first inner hexagonal hole, the size of the first inner hexagonal hole is adapted to the size of the locking nut; the sleeve tool has a simple structure, is easy to process, and is convenient and reliable to operate, avoiding the operator's hand bumping, and solving the problem of tightening or loosening fasteners with special installation methods in a narrow space;

[0003] The socket tool for subway vehicle maintenance disclosed in the above patent requires the use of an external ratchet wrench to rotate the socket tool to tighten or loosen the fastener during operation. This operation method still has some shortcomings when used: 1. When the locking force is large, manual rotation is more laborious and there is a situation where the tool cannot rotate; 2. The socket connector cannot be directly rotated for operation. The ratchet wrench is inserted into the socket connector for rotation. During the rotation process, there is a risk of slipping and loosening, which still causes the risk of injuring people's hands and cannot meet the use requirements. Based on the above situation, we propose a socket tool for subway vehicle maintenance. Utility Model Content

In addition, when the locking force is large, it can be adjusted through electric drive rotation, and the manual rotation and electric drive rotation can be switched according to the needs of use, thereby improving the flexibility of use.

[0027] Working principle: Before maintenance, the sleeve connector 101 is separated from the hexagonal connector 102 and the connecting sleeve 7. When the subway vehicle is being repaired and the empty weight valve setting value needs to be adjusted, the sleeve body 100 is sleeved on the fastening bolt, and then the sleeve connector 101 is sleeved on the hexagonal connector 102. The sleeve connector 101 drives the two positioning grooves 1 to be sleeved on the corresponding first magnets 3 respectively, and the first magnets 3 are attracted to the corresponding second magnets 2, so that the sleeve connector 101 and the hexagonal connector are connected. The connection between the angle connectors 102 is that after the socket connection, the handle rod 4 is located above the equipment, with a large space for convenient rotation. When only manual rotation is required, the total length of the retractable handle mechanism can be adjusted according to the use needs. When adjusting, the rubber sleeve 6 is held and rotated, and the rubber sleeve 6 drives the screw 5 to rotate. Under the action of the threaded hole opened on the handle rod 4, the screw 5 rotates and moves at the same time. When the screw 5 moves outward, the total length of the retractable handle mechanism increases. The required length can be adjusted according to the rotation needs. When the desired length is reached, the rubber sleeve 6 can be stopped from rotating, and by increasing the total length of the retractable handle mechanism, the force during rotation can be reduced. During rotation, the rubber sleeve 6 can be rotated around the sleeve connector 101, and the rubber sleeve 6 drives the handle rod 4 to rotate through the corresponding screw 5, and the handle rod 4 drives the sleeve connector 101 to rotate, and the sleeve connector 101 drives the sleeve body 100 to rotate through the outer hexagonal connector 102, the first magnet 3 and the second magnet 2. The sleeve body 100 rotates while driving the fastening bolt to rotate, so that the fastening bolt can be tightened or loosened, and the sleeve connector 101 and the outer hexagonal connector 102 are magnetically fixed by the first magnet 3 and the second magnet 2 during the rotation process, which can effectively reduce the slippage and loosening between the sleeve connector 101 and the outer hexagonal connector 102 during the rotation process, and the sleeve connector 101 is directly rotated by the handle rod 4, without inserting an external ratchet wrench, thereby further reducing the risk of slippage and loosening, and thus effectively reducing the risk of hurting hands;

[0028] When the locking force of the fastening bolt is large, the connecting sleeve 7 can be sleeved on the sleeve connector 101, and the connecting sleeve 7 drives the two card slots 13 to be movably sleeved on the corresponding fourth magnet 15, and the fourth magnet 15 is attracted to the corresponding third magnet 14, and then the drive motor 10 can be turned on. When the drive motor 10 is turned on, the drive motor 10 can be fixed by hand so that it does not rotate. When the drive motor 10 is turned on, its output shaft drives the gear 9 to rotate, the gear 9 drives the outer gear ring 8 meshing with it to rotate, the outer gear ring 8 drives the connecting sleeve 7 to rotate, and the connecting sleeve 7 drives the corresponding handle rod 4 to rotate through the rectangular groove 12. The handle rod 4 drives the sleeve connector 101 to rotate, and the sleeve connector 101 rotates the fastening bolt through the external hexagonal connector 102 and the sleeve body 100 in turn to tighten or loosen the fastening bolt. The driving motor 10 is driven to easily rotate the fastening bolt when the locking force is large, thereby effectively reducing the labor intensity. The manual rotation and the electric drive rotation can be switched according to the locking force to improve the flexibility of use. In addition, the handle rod 4 and the connecting sleeve 7 are magnetically fixed by the third magnet 14 and the fourth magnet 15, which can effectively improve the stability during the rotation process.
