Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical design technology, specifically relating to a quick replacement tool for tail-end hot chamber wire lighting fixtures. Background Technology
[0002] In the nuclear chemical reprocessing field, fixed lighting fixtures are widely used to illuminate the chambers within equipment rooms. Because these fixed fixtures are installed inside the upper chamber, far from the entrance, personnel wearing full-body air-cushioned suits must enter the upper chamber through an opening to retrieve the fixed fixtures from a pre-drilled transparent hole for replacement. After replacement, personnel, still wearing air-cushioned suits, must exit the upper chamber through the opening. However, during maintenance rehearsals, the numerous equipment and pipes within the upper chamber pose a significant risk of injury to personnel wearing air-cushioned suits, such as scratches or tears. Furthermore, this process is hampered by inconvenience, slow movement, and prolonged operation time. These factors combined result in low feasibility and safety for personnel entering the upper chamber to replace lighting fixtures.
[0003] Since the installation location of the lighting fixtures could not be changed on site, and to avoid insufficient cable length after multiple cable connector replacements before putting them into use, a certain length of cable was reserved for the lighting fixtures on site. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a quick replacement tool for the lighting fixtures in the tail end hot chamber, which enables maintenance personnel to complete the replacement and maintenance of fixed lighting fixtures in the hot chamber without entering the upper housing of the hot chamber.

[0011] A second handle is set at the center of the side of the wire winch. The wire cable is wound on the wire winch. The wire winch rotates as the second handle rotates, which is used to retract the wire cable.
[0012] One end of the telescopic rod is a telescopic structure for extending the telescopic rod, and the other end is provided with a second internal threaded hole for connecting with the rod body.
[0013] The telescopic rod has a hook welded to its front end. The hook has a C-shaped structure and is connected to the other end of a steel wire cable.
[0014] Connect the external thread structure at the first handle to the first internal thread hole at the rod body, connect the external thread post at the rod body to the second internal thread hole at the telescopic rod, tilt the C-hook downwards, and use gravity and the loosening of the wire winch to cooperate, the telescopic rod extends forward, and when the C-hook is hooked onto the housing of the lighting fixture, manually rotate the wire winch to retract the wire cable, shorten the telescopic rod, and move the lighting fixture to the upper box station.

The wire winch 4 is installed on the side of the rod and has a disc structure connected in parallel with the rod. One end of the rod is provided with a first internal threaded hole 2 for connecting with a first handle 1, and the other end is provided with an external threaded post 5 for connecting with a telescopic rod 8. A second handle 3 is set at the center of the side of the wire winch 4. The wire cable is wound on the wire winch 4. The wire winch 4 rotates with the second handle 3 to retract the wire cable.
[0032] like Figure 4 As shown, one end of the telescopic rod 8 is a telescopic structure for extending the telescopic rod 8, and the other end is provided with a second internal threaded hole 6 for connecting with the rod body. The front end of the telescopic rod 8 is welded with a hook 7, which is a C-shaped structure and is connected to the other end of a steel wire cable for continued contact and connection with the maintenance equipment.
[0033] When the lighting fixture in the heated room is damaged, connect the external threaded structure at the first handle 1 to the first internal threaded hole 2 at the rod body, and connect the external threaded post 5 at the rod body to the second internal threaded hole 6 at the telescopic rod 8, ensuring a secure connection. Tilt the C-hook 7 downwards, using gravity to loosen and engage with the wire winch 4, causing the telescopic rod 8 to extend forward. When the C-hook 7 is hooked onto the lighting fixture housing, manually rotate the wire winch 4 to retract the wire cable, shorten the telescopic rod 8, and move the lighting fixture to the upper housing opening. Release the C-hook 7 from the lighting fixture, connect the new lighting fixture to the C-hook 7, and use a quick-change tool to place the new lighting fixture back into the transparent pre-drilled pit.
