Description

Technical Field

[0001] The utility model relates to the technical field of copper bar processing, and more specifically to a device for sleeving heat shrinkable tubes on copper bars. Background Technique

[0002] Copper bars undertake important conductive tasks in high and low voltage switchgears. During the production process of high and low voltage switchgears, there is a process of sleeving heat shrinkable tubes on copper bars. The heat shrinkable tube is a special polyolefin material heat shrinkable sleeve, which has the functions of high temperature shrinkage, soft flame retardancy, and insulation and corrosion prevention. After the copper bar is sleeved with the heat shrinkable tube, it can play a role in insulation protection and prevent the risk of short circuit tripping caused by burrs, sharp corners, etc. on the surface of the copper bar.

[0003] However, since the main busbars of switchgears generally use copper bars with a width of 100 - 150 mm and a thickness of 10 - 12 mm, the longest of these copper bars is 6 meters and the maximum weight is over 90 kg. Therefore, the work of manually sleeving heat shrinkable tubes on copper bars not only has a high labor intensity but also has a low work efficiency. Based on this, the utility model provides a device for sleeving heat shrinkable tubes on copper bars. Summary of the Utility Model

A detachable length adjuster 4 is sleeved on the erection bracket 2, and a gripper 6 for placing the copper busbar 5 is fixedly provided at the bottom end of the length adjuster 4;

[0023] A coiling reel 7 is provided at the top of the base 1. A heat-shrinkable tube 8 is wound around the coiling reel 7. A limiting roller 18 is fixedly provided on one side of the top of the base 1. The limiting roller 18 is arranged between the coiling reel 7 and the base 1. The limiting roller 18 can play a role in limiting the heat-shrinkable tube 8, so as to avoid the deviation of the heat-shrinkable tube 8 and affect the installation efficiency. A hoist 9 is fixedly provided at the top end of the erection support 2. A towing rope 10 is wound around the hoist 9. The bottom end of the towing rope 10 is connected to the top of the heat-shrinkable tube 8. A support plate 11 is hinged to the side of the erection support 2 away from the copper busbar 5. The support plate 11 is slidably connected to the base 1. A feeding component 12 is provided on the erection support 2. The feeding component 12 is arranged outside the copper busbar 5 and the heat-shrinkable tube 8;

[0024] A chute 13 is formed at the top of the base 1. A slider 14 is slidably arranged in the chute 13. The top end of the slider 14 is movably connected to a reinforcing rod 15. The top end of the reinforcing rod 15 is movably connected to the erection support 2, which is used to improve the stability of the erection support 2 when it is erected;

[0025] To improve safety, a safety guardrail 16 is hinged to one side of the erection support 2. The safety guardrail 16 is arranged on one side of the copper busbar 5, and the safety guardrail 16 is detachably fixed to the erection support 2 to ensure that in case the copper busbar 5 falls off, it will not fall down and cause danger.

[0026] During use, the staff first lays the erection support 2 flat, then fixes the copper busbar 5 with the heat-shrinkable tube 8 to be installed on the gripper 6, relaxes the towing rope 10 on the hoist 9, connects one end of the towing rope 10 to the heat-shrinkable tube 8 on the coiling reel 7, and puts the head of the heat-shrinkable tube 8 into the tail of the copper busbar 5. Then, the reduction motor 17 is used to drive the rotating shaft 3 to drive the erection support 2 to rotate and stand up, so that the copper busbar 5 is suspended. Then, the hoist 9 is used to wind up the towing rope 10, and the towing rope 10 is used to drag the heat-shrinkable tube 8 to be sleeved on the copper busbar 5. When the head of the heat-shrinkable tube 8 reaches the top, the hoist 9 is stopped. Finally, the erection support 2 is laid flat and the gripper 6 is loosened, and the copper busbar 5 sleeved with the heat-shrinkable tube 8 is removed by using the feeding component 12. By using the above structure to install the heat-shrinkable tube 8, the labor intensity is greatly reduced and the work efficiency is improved compared with manual operation.
